Wherein, the base is provided with a passage; the capsule holder , at least partially received in the passage, is slidably mounted on the base , capable of directionally sliding along the passage. The injection module is movably connected with the base and can get close to or away from the capsule holder in a preset direction. The power module is connected with the injection module for driving the injection module to get close to or away from the capsule holder in the preset direction. One end of the sliding rail is carried at one end of the capsule holder proximate to the injection module and used for carrying a flange of a capsule ; the other end of the sliding rail is rotatably mounted on the capsule holder . The driving module is configured to drive the sliding rail to rotate when the injection module is getting away from the capsule holder in the preset direction, so that the end of the sliding rail carried on the capsule holder gets away from the capsule holder .With regard to the base , reference is made to which shows a perspective view of the base in combination with , the base includes two oppositely disposed side plates , and a connecting plate having both ends connected with the two side plates , respectively. Each side plate is vertically disposed, and the connecting plate is used for connecting the two side plates so that the two side plates are oppositely arranged and fixed relative to each other, thereby forming the above-mentioned passage .With regard to the capsule holder , reference is made to which shows a perspective view of the capsule holder in combination with , the capsule holder includes a cup holder , a slider , and a push plate . An accommodating cavity for accommodating the capsule is provided at the end, proximate to the injection module , of the cup holder (i.e., the top as shown). The slider is generally strip-shaped, the two sliders are arranged on two opposite sides of the cup holder in parallel, and the sliders extend in a direction extending parallel to the passage . The two side plates are respectively provided at one end facing the passage with guide grooves adapted to the sliders and extending in a direction extending parallel to the passage , and the pair of sliders are mated with the pair of guide grooves to ensure that the capsule holder can slide directionally in the passage . The push plate is fixedly connected with one end of the slider and facilitates pulling the capsule holder out of the accommodating cavity to the exterior of the passage for the capsule to fill in, as well as pushing the capsule holder into a set position to conduct the subsequent brewing process.With regard to the injection module described above, reference is made to which shows a perspective view of the injection module in combination with , the injection module includes an injection component and a connecting arm . The injection component is disposed in the passage and positioned on one side of the capsule holder where the accommodating cavity is provided, specifically, above the accommodating cavity . The injection component serves to pierce a sealing membrane of the capsule and inject boiled water into the capsule to complete the brewing process. One end of the connecting arm is fixedly connected with the injection component , and the other end of the connecting arm extends away from the push plate in a direction parallel to the passage and is rotatably mounted on the base ; that is, the direction in which the injection module rotates in the present embodiment is the preset direction described above. In the present embodiment, the number of the connecting arms is two, and the two connecting arms are respectively arranged on two sides of the injection component along the direction of width of the passage ; one end of each connecting arm distal to the injection component is connected with a rotating shaft , the side plate is provided with a rotating hole () matched with the rotating shaft , and the connecting arm and the side plate are rotatably connected through the matching of the rotating shaft and the rotating hole. At the brewing working position, the injection module is positioned close to an opening of the accommodating cavity , and generally, almost parallel to the capsule holder ; starting from such a position, the injection module reaches the sliding-down working position (shown in ) after being rotated by a preset angular displacement in a direction away from the accommodating cavity . It will be appreciated that in other embodiments of the present application, the connecting arm may be rotatably connected with the side plate in other ways. For example, in some embodiments of the present application, the rotating shaft is sleeved with a bearing, an inner race of which is in interference fit with the rotating shaft, and an outer race of which is fixed to the side plate , that is, the connecting arm is rotatably connected with the side plate through a bearing.With regard to the power module , reference is made to in combination with , the power module is connected with the injection module and configured to drive the injection module to reciprocate between the brewing working position and the sliding-down working position, and the power module includes a first link , a second link , and a rotation mechanism . One end of the first link is rotatably mounted on the injection component of the injection module, the other end of the first link is rotatably connected with the second link , an output end of the rotation mechanism is connected with the second link and configured to drive the second link to rotate; the base , the second link , the first link and the injection module together form a four bar linkage, so that regular movement of the injection module can be rendered by driving the second link by the rotation mechanism . In the present embodiment, the rotation mechanism is an electric motor, and it will be appreciated that in other embodiments of the present application, the rotation mechanism may be any mechanism that can achieve rotational output, such as a rotating cylinder.Further, the rotation mechanism further includes a worm gear and a worm, through which the rotation mechanism is connected with the second link to reduce the rotation speed of the injection module to a certain extent and avoid damage caused by strong impact between the injection module and the capsule holder due to too fast rotation of the motor. The worm gear is coaxially and fixedly connected with a worm gear shaft, the worm gear shaft is rotatably mounted on the base , and the second link is sleeved on and fixed with the worm gear shaft. And the worm is matched with the worm gear and connected with the output end of the rotation mechanism.With regard to the sliding rail , reference is made to which respectively show a perspective view of the sliding rail and a schematic view showing the connection of the sliding rail and the capsule holder in combination with , the sliding rail includes a sliding guide part , one end of which is carried at one end of the cup holder proximate to the injection component , the other end of which extends away from the push plate in a direction extending parallel to the passage and is rotatably mounted on the capsule holder . The end of the sliding rail carried on the cup holder is disposed at an edge of a profile of the accommodating cavity and used for carrying the flange of the capsule .Further, the sliding rail further includes a bent part having one end connected with one end of the sliding guide part distal to the accommodating cavity and the other end extending towards a bottom of the base . In the present embodiment, one end of the bent part distal to the cup holder extends towards the bottom of the base and gradually gets away from the cup holder . Actually, the bent part can be formed by bending a straight sliding rail, and on one hand, the distance between the two ends of the straight sliding rail can be reduced by the configuration of the bent part , so that the travel of the capsule is shortened; on the other hand, when the sliding rail is rotated by a certain angle, the capsule slides down, the bent part has a certain inclination angle relative to the sliding guide part , and the capsule slides on the bent part with less resistance, so that the bent part can accelerate the falling of the capsule when the capsule slides down to the bent part .In addition, the sliding rail having the bent part enables a greater inclined angle of the sliding guide part when the end of the sliding rail carried at one end of the cup holder rises by the same height as that of the straight sliding rail having the same total length does. To facilitate understanding, reference is made specifically to which is a schematic view showing a straight sliding rail and the sliding rail having the bent part being respectively rotated until their ends proximate to the cup holder reach the same height in combination with other drawings. As shown in the drawings, point O and point X respectively represent two ends of the straight sliding rail when the straight sliding rail is horizontal, point Y represents a position of the straight sliding rail after the end thereof proximate to the cup holder being rotated by angle α along a circle centered in point O, and circle P is a movement track of the end of the straight sliding rail proximate to the cup holder, that is, the end of the straight sliding rail proximate to the cup holder is rotated from a horizontal position at point X by angle α to point Y along a circle centered in point O. Similarly, points O′ and M represent both ends (O′M=OM) of the bent part of the sliding rail having the bent part, points M and X represent both ends of the sliding guide part of the sliding rail having the bent part, point Z represents the position of the sliding rail having the bent part after its end proximate to the cup holder being rotated by angle β along a circle centered in point O′, and points Z and Y are at the same height relative to the horizontal position, and circle Q is a movement track of the end, proximate to the cup base, of the sliding rail having the bent part, namely: the end of the sliding rail with the bent part proximate to the cup holder rotates from a horizontal position point X to point Z by angle β along a circle centered in point O′. The rotation angle of the sliding rail is generally less than 90 degrees, and within such a range, the track of the circle Q is always on the left side of the track of the circle P, then:Lxz>Lyz, wherein L represents chord length;and RO′Z<ROY, wherein R represents radius;In addition, a chord length formula can be combined: L=2R*sin (θ/2), wherein L represents chord length and θ represents radian;It can be inferred that β is greater than α, that is, the angle by which the sliding rail having the bent part rotates is greater than the angle by which the straight sliding rail rotates. A horizontal piece has an included angle γ with the horizontal direction after being rotated by angle γ along a circle centered in any point, regardless of the choice of the rotation center, so the angle between the sliding guide part and the horizontal direction is β, which is larger than the included angle α of the straight sliding rail with the horizontal direction. Therefore, the sliding rail having the bent part provided by the present embodiment is more favorable for the capsule to slide down.Furthermore, in order to render a more reliable process to bring the capsule out of the accommodating cavity by the sliding rail , the sliding guide part of the sliding rail is U-shaped. Reference is made to in combination with other drawings, the U-shaped structure of the sliding guide part is disposed around the edge of the accommodating cavity , and both ends of the U-shaped structure extend in a direction parallel to the passage . The two bent parts are respectively connected with two ends of the sliding guide part distal to the accommodating cavity . Each bent part is connected with a pin shaft arranged in parallel with the rotating shaft , the two pin shafts extend in opposite directions, in the present embodiment, one end of each pin shaft is connected with the bent part , the other end of each pin shaft extends away from the center of the passage , and the sliding rail is rotatably mounted on the slider of the capsule holder through the pin shaft . The sliding guide part is of a U-shaped structure, so that the area of the sliding rail for bearing the capsule is increased, and the process of bearing the capsule by the sliding rail is more reliable; moreover, the sliding rail is also U-shaped, and the structure cooperates with the pin shaft so that the sliding rail is not easily disengaged after being mounted on the capsule holder .With regard to the driving module, reference is made to in combination with and others, the driving module is used to drive the sliding rail to rotate when the injection module is getting away from the capsule holder in the preset direction, so that one end of the sliding rail carried on the capsule holder gets away from the capsule holder and brings the capsule out of the accommodating cavity . The driving module includes a clamping hook and a clamping strip , wherein the clamping hook is arranged on the sliding rail and includes a connecting part and a hooking part , one end of the connecting part is connected with the sliding guide part of the sliding rail , the other end of the connecting part extends to the connecting arm of the injection module , and the hooking part is arranged at one end, distal to the sliding rail , of the connecting part on a side of the connecting part proximate to the center of the passage . The clamping strip is provided at the connecting arm of the injection module , extends integrally in a direction parallel to the passage , and is located between the sliding rail and the hooking part . At the brewing working position, the clamping strip is positioned on a side of the hooking part proximate to the capsule holder. When the injection module is moving to the sliding-down working position under the drive of the power module , the clamping strip can abut against the hooking part of the clamping hook and drive the sliding rail to rotate along with the clamping hook , so that one end of the sliding rail gets away from the capsule holder and brings the capsule out of the accommodating cavity ; when the sliding rail is rotated by a certain angle, the capsule will slide down in the direction in which the sliding rail extends under the action of gravity and fall into a designated container. And after the capsule slides off, the sliding rail continues to rotate along with the injection module until the hooking part of the clamping hook moves to the end of the clamping strip with respect to the clamping strip and is disengaged with the clamping strip (shown in ), at which time, the sliding rail rotates towards the capsule holder under the action of gravity until the end proximate to the capsule holder is carried on the capsule holder . During the movement of the injection module from the sliding-down working position to the brewing working position under the drive of the power module , the clamping strip first abuts against the hooking part of the clamping hook , renders the clamping hook to be opened in a direction away from the center of the passage by the elasticity of the clamping hook , and then enables the return to the brewing working position by passing over the hooking part .Further, the distance between the two hooking parts becomes smaller in a direction from the hooking part to the sliding guide part to provide guide for the clamping strip to pass over the hooking part , thereby preventing the clamping strip from being directly pressed onto the hooking part to damage the clamping hook .It should be understood that even though the clamping hook in the above embodiment is provided on the sliding rail and the clamping strip is provided on the injection module , the present application is not limited thereto; for example, in other embodiments of the present application, the clamping hook may also be provided on the injection module and extend in a direction towards the sliding rail, and accordingly, the clamping strip may be provided on the sliding rail between the injection module and the hooking part of the clamping hook.Furthermore, in order to facilitate control of the power module that can be stopped in time when the injection module moves to the brewing working position, so that the injection module can conduct the subsequent brewing process, the brewing device further includes a first sensor and a controller (not shown), the first sensor and the rotation mechanism being both connected with the controller. Specifically, reference is made back to in combination with the other drawings, the first sensor is fixed to the side plate and corresponds to the position of the second link . When the injection module moves to the brewing working position, the second link moves to abut against the first sensor and triggers the first sensor ; the controller controls the rotation mechanism to stop operating in response to the trigger signal, and the injection module stays stably at the brewing working position.Similarly, in order to control the power module to stop operating as required when the injection module moves away from the capsule holder until the sliding rail disengages with the injection module , so as to ensure consistent displacements of the injection module each time it moves away from the capsule holder , the brewing device further includes a second sensor , which is also connected with the controller. The second sensor is fixed to the side plate and corresponds to the position of the connecting arm . The second sensor serves to abut against the connecting arm of the injection module and get triggered during rotation of the injection module in a direction away from the capsule holder , so that the controller controls the rotation mechanism to stop operating in response to the trigger signal, thereby stopping the movement of the injection module . It will be appreciated that the injection module triggers the second sensor after the sliding rail disengages with the injection module .It will be appreciated that the capsule may be a coffee capsule or other capsules such as a fruit tea capsule, and the working mechanism of the brewing device according to the present application will be briefly described with reference to the drawings, taking the coffee capsule as an example.In an initial state, the capsule holder is accommodated in the passage , the capsule is not provided in the accommodating cavity , and the injection module is at the sliding-down working position.When it is desired to brew coffee, at first, the push plate is pulled until the accommodating cavity is exposed out of the passage , the capsule is filled in the accommodating cavity , and the push plate is pushed until the position of the capsule corresponds to the brewing working position. The power module is then controlled to move the injection module from the sliding-down working position to the brewing working position. After this, the injection module is controlled to brew with the capsule . After the brewing is complete, the power module is controlled to drive the injection module to move from the brewing working position to the sliding-down working position; during the process, the sliding rail rotates along with the injection module under the drive of the driving module and brings the capsule out of the accommodating cavity ; when the sliding rail rotates by a certain angle, the capsule slides downwards along the extending direction of the sliding rail and falls into a designated container; after the capsule slides off, the sliding rail continues to rotate along with the injection module until the clamping hook arranged on the sliding rail is completely disengaged from the clamping strip arranged on the injection module , and then the sliding rail reversely rotates to the initial position under the action of gravity; injection module continues to move to the sliding-down working position under the drive of power module . Until then, one cycle of brewing process is complete.The brewing device provided by the present embodiment of the present application includes a base , a capsule holder , an injection module , a power module , a sliding rail and a driving module, compared with a brewing device in a beverage machine currently available on the market. Wherein, the capsule holder is provided with an accommodating cavity for accommodating the capsule ; one end of the sliding rail is used for bearing the capsule , the other end of the sliding rail is rotatably mounted on the capsule holder , and after the brewing process is complete, the driving module can drive the sliding rail to rotate along with the injection module when the injection module is getting away from the capsule holder in a preset direction, so that the sliding rail brings the capsule out of the accommodating cavity of the capsule holder , and the capsule slides down the sliding rail to a designated position. Therefore, the brewing device provided by the present embodiment of the present application can realize automatic recovery of the used capsule without manual operation by a user, and effectively improves the user experience.It should be understood that, in the above embodiment, the injection module is rotated to get away from the capsule holder , but the present application is not limited thereto; for example, in other embodiments of the present application, the injection module may be moved away from the capsule holder in a translational manner in a direction of a depth of the accommodating cavity , and it will be appreciated that it is still possible to move the sliding rail along with the injection module , and the preset direction mentioned above is the direction in which the injection module is translated.Reference is made to which shows a perspective view of a brewing device provided according to another embodiment of the present application in combination with , the brewing device differs from the brewing device in the first embodiment mainly in that:the driving module in the first embodiment includes a clamping hook and a clamping strip , and the sliding rail is driven by the cooperation of the clamping hook and the clamping strip to realize the recovery of the capsule ; anda driving module in the present embodiment is not provided with a clamping hook or a clamping strip, but includes a first magnetic piece and a second magnetic piece , and by means of mutual attraction of the first magnetic piece and the second magnetic piece , the sliding rail is driven to rotate during movement of the injection module in a direction away from the capsule holder, thereby realizing recovery of the capsule .Specifically, reference is made to which respectively show a perspective view of an injection module from one angle and a perspective view of a sliding rail from one angle according to the present embodiment in combination with , a first magnetic piece is provided on the connecting arm of the injection module , and a second magnetic piece is provided at the position of the sliding rail corresponding to the first magnetic piece . One of the first magnetic piece and the second magnetic piece is an electromagnet which generates a magnetic field in a specific direction when powered on, and when the electromagnet is powered off, the magnetic field disappears; the other of the first magnetic piece and the second magnetic piece is a magnetic plate made of a magnetic material such as iron, cobalt, nickel or an alloy thereof. In the present embodiment, the first magnetic piece is an electromagnet and the second magnetic piece is a magnetic plate, and the brewing device is briefly described with reference to .One end of the magnetic plate is connected with the sliding rail , and the other end of the magnetic plate extends towards the connecting arm of the injection module until corresponding to the electromagnet. When the injection module rotates away from the capsule holder, the electromagnet is powered on, the magnetic plate and the sliding rail rotate along with the injection module under the adsorption action of the electromagnet, so that the capsule is brought out of the accommodating cavity, and the capsule slides down the sliding rail to a designated position to realize the recovery of the capsule; when the sliding-down process is complete, the electromagnet is powered off, the gravitational field between the magnetic plate and the electromagnet disappears, and the sliding rail reversely rotates to the capsule holder and rests thereon under the action of gravity.Compared with the first embodiment, the capsule recovery and the resetting of the sliding rail are realized by controlling the power-on and power-off of the electromagnet, the electromagnet and the magnetic plate can be not contacted, and the failure caused by repeated contact friction of structures such as hooks, clamping strips and the like can be avoided. the present embodiment where the first magnetic piece is a magnetic plate and the second magnetic piece is an electromagnet is substantially the same as the above-described embodiment and will not be described in detail herein.It should be understood that, even though one of the first magnetic piece and the second magnetic piece is an electromagnet and the other is a magnetic plate in the above embodiment, the present application is not limited thereto; for example, in other embodiments of the present application, both the first magnetic piece and the second magnetic piece may be electromagnets. Specifically, during rotation of the injection module in a direction away from the capsule holder, the first magnetic piece and the second magnetic piece are powered on, so that the polarity of the ends of the first magnetic piece and the second magnetic piece in proximity is opposite, and then the sliding rail rotates along with the injection module and recovers the capsule to a specified position; after the capsule recovery is complete, the first magnetic piece and the second magnetic piece are powered on, so that the polarity of the ends of the first magnetic piece and the second magnetic piece in proximity is the same, the sliding rail is reset under the repelling action of the first magnetic piece, the first magnetic piece and the second magnetic piece can be powered off at the same time, and then the sliding rail is reset under the action of gravity. For another example, in still other embodiments of the present application, one of the first magnetic piece and the second magnetic piece is an electromagnet, and the other of the first magnetic piece and the second magnetic piece is a magnet. During the rotation of the injection module in a direction away from the capsule holder, since the iron core of the electromagnet itself is a soft magnetic material, the first magnetic piece and the second magnetic piece are attracted to each other (apart from this, the first magnetic piece may also be powered on, so that the polarity of the ends of the first magnetic piece and the second magnetic piece in proximity is opposite, and then the first magnetic piece and the second magnetic piece can be attracted to each other), and therefore the sliding rail rotates along with the injection module and realizes capsule recovery; when the capsule is recovered, the first magnetic piece may be powered on, so that the polarity of the ends of the first magnetic piece and the second magnetic piece in proximity is the same, and then the sliding rail is reset under the repelling action between the first magnetic piece and the second magnetic piece.Reference is made to which respectively show a perspective view of a brewing device , and a perspective view of the sliding rail provided in yet another embodiment of the present application from two angles, as well as an enlarged view at B, in combination with , the brewing device differs from the brewing device in the second embodiment mainly in that:the driving module of the brewing device in the second embodiment includes a first magnetic piece and a second magnetic piece, wherein the first magnetic piece is arranged on the injection module, the second magnetic piece is arranged on the sliding rail, one of the first magnetic piece and the second magnetic piece is an electromagnet, the other one of the first magnetic piece and the second magnetic piece is a magnetic plate, a magnet or an electromagnet which can be attracted by the electromagnet, and the recovery of the capsule is realized through the cooperation of the first magnetic piece and the second magnetic piece; andthe driving module of the brewing device in the third embodiment still includes a first magnetic piece and a second magnetic piece, wherein the first magnetic piece is arranged on the injection module, and the second magnetic piece is arranged on the sliding rail, one of the first magnetic piece and the second magnetic piece is a magnet and the other is a magnetic plate made of a magnetic material such as iron, cobalt, nickel and the like or an alloy thereof. Hereinafter, for example, the first magnetic piece is a magnet and the second magnetic piece is a magnetic plate, and the present embodiment will be briefly described with reference to the accompanying drawings.After the brewing is complete, when an injection module rotates in a direction away from the capsule holder, the first magnetic piece and the second magnetic piece are attracted to each other, and then the second magnetic piece and a sliding rail rotate along with the injection module under the attraction of the first magnetic piece, so that the capsule is brought out of the accommodating cavity and slides down the sliding rail to a designated position to realize the recovery of the capsule. When the capsule needs to be refilled, the user only needs to pull out the capsule holder by means of the push plate, the second magnetic piece is displaced along with the capsule holder until the second magnetic piece is disengaged from the attraction of the first magnetic piece, and the sliding rail is reset under the action of gravity.Compared with the second embodiment, the brewing device provided by the present embodiment does not use an electromagnet, so that the cost of circuitry is reduced, and the electric energy can be saved to a certain extent.Furthermore, the brewing device provided in the present embodiment can realize successfully capsule recovery through the cooperation of the first magnetic piece and the second magnetic piece, and the user experience is improved; however, after the capsule is recovered, the sliding rail cannot be automatically reset in time, but is passively reset in the process of pulling out the capsule holder. The reset process of the sliding rail is not stable because the force applied by the user each time can vary greatly, the sliding rail may damage the injection module and the capsule holder when the force applied by the user is too vigorous. In order to eliminate such a defect, the brewing device provided by the present embodiment further includes a limiting module used for preventing the sliding rail from continuing to rotate along with the injection module when the sliding rail rotates away from the capsule holder for a set angular displacement, so that the sliding rail is reset under the action of gravity. Notably, before the sliding rail rotates for the preset angular displacement, the capsule has been recovered.Specifically, reference is made to and in combination with , the limiting module includes a first limiting part disposed on the sliding rail and a second limiting part disposed on the base, the first limiting part and the second limiting part abut against each other while the injection module moves away from the capsule holder, so that the sliding rail stops following the rotation of the injection module and resets under the action of gravity. In the present embodiment, the first limiting part is a limiting column connected with the bent part of the sliding rail through a connecting column ; one end of the connecting column is connected with one end of the bent part distal to the sliding guide part, the other end of the connecting column extends away from the sliding guide part and simultaneously extends upwards, the limiting column is arranged at one end of the connecting column distal to the bent part and extends in parallel with the pin shaft; the second limiting part is a limiting plate horizontally fixed at one end, distal to the push plate of the capsule holder, of the side plate. When the injection module is in the brewing state, the limiting column is positioned above the limiting plate, and when the injection module moves to the sliding-down working position, the limiting column rotates to abut against the limiting plate with the pin shaft as a rotation center, so that the sliding rail does not move along with the injection module any longer, and the sliding rail can be reset under the action of gravity.It should be understood that, in other embodiments of the present application, the first limiting part and the second limiting part may be of other structures, for example, the first limiting part is a limiting plate, and correspondingly, the second limiting part is a limiting column, as long as the first limiting part and the second limiting part are used for cooperating together to prevent the sliding rail from continuing to rotate with the injection module when the sliding rail rotates a preset angular displacement in a direction away from the capsule holder; the limit module may also be applied to the second embodiment to prevent the sliding rail from continuing to rotate with the injection module when the slide rotates a preset angular displacement away from the capsule holder.It should also be understood that, in other embodiments of the present application, the first magnetic piece and the second magnetic piece may each be a magnet, and a substantially the same manner as the above embodiment by which capsule recovery and sliding rail resetting are accomplished is provided, and thus such an embodiment will not be described in detail herein. Moreover, it can be seen by referring to the above second embodiment that the combination of the first magnetic piece and the second magnetic piece is various, so long as it is ensured that the first magnetic piece and the second magnetic piece can be mutually attracted when the injection module is getting away from the capsule holder in the preset direction, and thus one end, proximate to the cup holder, of the sliding rail gets away from the capsule holder to complete the recovery of the capsule.Reference is made to which show a perspective view of a brewing device according to still another embodiment of the present application with the side plate not shown, and a partially enlarged view at C, in combination with , the brewing device differs from the brewing devices of the first, second and third embodiments in that:the driving module of the brewing device in the first embodiment includes a clamping hook and a clamping strip, and the driving module of the brewing devices in the second embodiment and the third embodiment include a first magnetic piece and a second magnetic piece;while a driving module in the present embodiment includes a rotation mechanism having an output connected with a sliding rail , for driving the sliding rail to rotate during the movement of the injection module away from the capsule holder so that the sliding rail brings the capsule out of the accommodating cavity and slides it to a designated position, the rotation mechanism is also used for driving the sliding rail to reset after the capsule is successfully recovered. In the present embodiment, the rotation mechanism is an electric motor, and it will be appreciated that in other embodiments of the present application, the rotation mechanism may also be a rotary cylinder or other mechanisms capable of rendering a rotational output, which is not limited herein.Furthermore, in order to avoid interference between the sliding rail and the injection module due to too high rotation speed of the output of the rotation mechanism , the driving module further includes a first gear and a second gear , wherein the first gear is fixedly connected with the output end of the rotation mechanism , and the second gear is coaxially sleeved on the pin shaft of the sliding rail , that is, the rotation mechanism changes speed by means of the first gear and the second gear , so that the sliding rail can have an appropriate rotation speed, capable of taking out the capsule and avoiding interference with the injection module .According to the brewing device provided by the present embodiment of the present application, the self-service recovery of the capsule can also be realized, and the user experience can be effectively improved.On the basis of the same concept, the present application also provides a beverage machine including a housing and the brewing device as provided in any of the above embodiments. By advantage of the brewing device, the beverage machine can realize self-service recovery of the capsule, and the user experience can be effectively improved.Finally, it should be noted that the above examples are intended only to illustrate the technical solutions of the present application, not to be limiting; the above embodiments or technical features in different embodiments may also be combined, the steps may be carried out in any order according to the idea of the present application, and many other variations in different aspects of the present application as described above exist, which are not provided in detail for the sake of brevity; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions of the above embodiments can still be modified, or some of the technical features thereof may found their equivalents; and these modifications and equivalents do not render departures from the scope of the present embodiments of the present application.
