Steam floor brush

The current floor cleaning mops are generally classified into two types: one is the traditional floor mop which can be used for the dry cleaning work, and is not suitable to realize a wet cleaning purpose; therefore, its application is limited; the other is the floor cleaning mop having a steam distributing function, with which the water is firstly heated vaporized to generate steam which is then distributed to the floor for the cleaning work so as to realize the effect of high-temperature disinfecting and sterilizing. However the current steam floor mop has the following drawbacks: when in use, the water needs to be provided firstly to the steam generator by powering on the water pump additionally, and then is heated vaporized to generate steam for the cleaning work, this process takes such a long time that its application is inconvenient; in addition, the cleaning work has to be performed repeatedly many times in order to obtain a thorough cleaning effect, it is time-consuming and tiring. The main reasons for the above problems are that:

most of the cleaning surface of the current mop is flat, which is bad for the steam distributing to the whole cleaning surface, and thus results in the consequence that the cleaning surface can not be wetted uniformly, some portion of the cleaning surface is too dry while some portion is too wet, and that, the effect of high-temperature disinfecting and sterilizing can not be realized; moreover, the cleaning cloth serves to cover the floor brush is too smooth without any pattern or stripe that the stains adhered to the floor cannot be cleaned easily.

SUMMARY OF THE INVENTION In view of the above-described problems, it is an objective of the present invention to provide a steam floor mop with which the steam can be distributed instantaneously to the floor brush so as to perform the cleaning work by only pushing the handle of the steam floor mop.

A water pump inlet mouth 42 and a water pump outlet mouth 43 are formed at the lower end of said manual water pump 4, wherein said water pump inlet mouth 42 is connected to the water tank 5 by means of a first pipe A; said water pump outlet mouth 43 is connected to a water inlet mouth 61 of the steam generator 6 by means of a second pipe B; a steam exit 62 of the steam generator 6 is connected to the floor brush 3 by means of a third pipe C. During performing the cleaning work using the steam floor mop, by only pushing the handle 1 of the steam floor mop, the piston rod 41 at the top end of the manual water pump 4 is pushed by the handle 1; water is fed into the steam generator 6 by means of the manual water pump 4, and then is heated vaporized to generate steam by the steam generator 6; the generated steam firstly flows into the floor brush 3 by the third pipe C, and then flows into the cleaning cloth 7 covered on the floor brush 3; the cleaning work having an effect of high temperature disinfecting and sterilizing can be realized by using the steam with the cleaning cloth 7. It is not needed to power on the water pump additionally so as to supply water to the steam generator to generate the steam.

A handle cover 11 that can socket with the handle 1 and serves to limit the moving range of the handle 1 is also located on a top end of the body 2, and the upper end of the handle cover 11 is fixed on the body 2.

As shown in FIGS. 3-7, the floor brush 3 is a fan-shaped brush, a steam inlet mouth 33 is further provided at the floor brush 3, and is connected to the water outlet mouth 62 of the steam generator 6 by means of the third pipe C. A buffer area 34 is provided around the center steam inlet mouth 33 of the floor brush 3 and serves mainly to buffer the pressure and speed of the steam in order to guide smoothly the flow of the steam. A plurality of rib strips 35 is extended from the center of the buffer area 34 and a plurality of steam distributing grooves 36 is formed between the rib stripes. In this way, the steam can be distributed uniformly to the whole cleaning surface of the floor brush, the excessive steam can be vented out and thus the excessive moisture of the cleaning cloth 7 can be avoided. Besides, a peripheral edge 37 is set around the rim of the floor brush 3, and is 0.5-2 mm higher than the rib stripes As shown in. FIGS. 9-10, the manual water pump 4 comprises a pump body 47, a piston rod 41, a water pump inlet mouth 42, a water pump outlet mouth 43, a one-way inlet pump core 44, and a one-way outlet pump core 45. A piston cavity 46 of said pump body 47 is a stepped cavity, where the upper cavity has a larger diameter than the lower cavity. The one-way inlet and outlet pump cores 44, 45 are made of elastic material and have a top structure that can be opened after an elastic deformation so as to form a two-layered antibackpressure apparatus, thereby to against the backpressure of the steam generator 6, and thus to prevent the pump cores from being broken down by the backpressure of the steam generator 6, as well as to control the one-way flow of the water. Namely, the manual water pump 4 can be regarded us a one-way automatic artificial intelligent feed pump, and by pushing the handle 1 of the steam floor mop, the piston rod 41 of the manual water pump 4 can be operated to push automatically the pump water to the steam generator 6.

As shown in FIG. tl, the steam generator 6 comprises a conical shell 63 and a heating core 64, wherein a water inlet mouth 61 is formed at the bottom end of the heating core 64, and a plurality of electrical heating bodies 65 is die cast and a handstand conical cavity 66 is formed inside the heating core 64; a steam collection room 67 is provided inside the conical shell 63 and is positioned opposite to the conical cavity 66; a slidable steam separating cover 68 is located between the steam collection room 67 and the heating core 64, a steam collecting mouth 69 for connecting the conical cavity 66 to the steam collection room 67 is provided at the center of the steam separating cover 68, and a steam exit 62 is provided on the top end of said steam collection room. In addition, a plurality of C-shaped guide rings 641 is set at the water inlet mouth 61 on a bottom end of the heating core 64, and is served to separate the flow of the water in order to distribute the water uniformly to the whole surface of the heating core.

As shown in FIG, 8, the cleaning cloth 7 is in a shape of vest, a pair of fixing straps 71 is extended from the upper portion of the cleaning cloth 7; a magic female tape 72 is affixed on each of said fixing straps 71, a pair of magic male tapes 73 that can be pasted fixed with the magic female tapes 72 is affixed on a lower portion of the cleaning cloth 7. The size of the cleaning cloth 7 that is matchable with the size of the floor brush is applied to cover the floor brush 3 tightly. A plurality of #-shaped grilles are formed on the surface of the cleaning cloth so that the stains adhered on the floor can be cleaned easily. The cleaning cloth 7 covered at the upper portion of the floor brush 3 is applied to encase the excessive steam and thusly two sides thereof are heated; the cleaning cloth that covered on the lower portion of the floor brush 3 is used for cleaning the floor.

As stated above, a plurality of rib strips 35 is provided at the floor brush and a plurality of steam distributing grooves 36 is formed between the rib stripes 35, so that the steam can be distributed uniformly to each corner of the floor brush, and the humidity can be balanced. As a result, by using the cleaning cloth formed with #-shaped grilles thereon and covering the floor brush 3 tightly, a cleaning work can be performed conveniently and is time and labor saving, and the effect of high temperature disinfecting and sterilizing can be realized.
