The chip (20) is mounted on the ink cartridge (10), and the ink cartridge (10) is mounted in a mounting portion (90) in a printer along a mounting direction. The chip (20) comprises a memory, first contact portions (201a, 204a, 205a, 209a) and second contact portions for mounting detection. At least one second contact portion is electrically connected to the memory. The first contact portions (201a, 204a, 205a, 209a) and the second contact portions are separately in contact with contact pins (91a) in the printer. The first contact portions (201a, 204a, 205a, 209a) are arranged in multiple rows in the mounting direction. In the mounting direction, one or more rows formed by the second contact portions is provided between the multiple rows formed by the first contact portions (201a, 204a, 205a, 209a); or the multiple rows formed by the first contact portions (201a, 204a, 205a, 209a) are provided between the multiple rows formed by the second ...

INK CARTRIDGE

Disclosed is an ink cartridge, which is detachably mounted to a mounting part (3) of a printing device. The ink cartridge comprises a housing (29) and a snapping joint (22) arranged on the housing. The snapping joint can be snapped to a force-applying component of the printing device so as to fix the ink cartridge to the mounting part, and the snapping joint can be separated from the force-applying component so as to release the ink cartridge from the fixation with the printing device. According to the ink cartridge, by means of snapping and separating the snap joint and the force-applying component, the fixing method of locating the ink cartridge with a handle can be dispensed with.

ADAPTER FOR INK TANK AND INK CARTRIDGE COMPRISING ADAPTER

Disclosed are an adapter for an ink tank and an ink cartridge comprising the adapter. The adapter (2) for an ink tank comprises a main body (4) capable of accommodating an ink tank (3), and the main body is provided with a limiting component (11) disenabling identification of whether the ink cartridge is normally installed when the ink tank is firstly installed into the adapter and then into a printer. When a user installs an ink tank firstly into the adapter and then into the printer, the printer is unable to identify whether the ink cartridge has been normally installed, thereby preventing the user from firstly assembling the adapter and the ink tank and then installing same into the printer. The technical problem of an existing adapter for an ink tank and an existing ink cartridge comprising the adapter being unable to prevent a user from firstly installing an ink tank into the adapter and then into the printer is solved, which otherwise results in an incorrect judgement of ink cartridge ...

Ink box

The ink box comprises an ink box body, a gas-liquid exchange cavity, a main ink storage cavity and a gas guide cavity are formed in the ink box body, the gas-liquid exchange cavity forms an outer connector on the outer wall face of the ink box body, and a gas inlet and a main liquid inlet are formed in the inner wall face of the gas-liquid exchange cavity; the sealing piece is arranged in the gas-liquid exchange cavity, the gas inlet and the main liquid inlet are located in the two opposite sides of the sealing piece, and the gas inlet is closer to the outer connector than the sealing piece; the outer connector is provided with a first end and a second end, the first end is farther away from the sealing piece than the second end, the air inlet is arranged close to the first end, and the projection of the air inlet in the second direction is staggered with the sealing piece or partially falls on the sealing piece. According to the ink box, the air inlet is formed in the first end portion ...

SNAP-FIT CARTRIDGE

Disclosed is a snap-fit cartridge which is removably mounted in a mounting part. The mounting part is provided with a mounting surface (39) inclined relative to a horizontal plane, the end of the mounting surface (39) which is close to the cartridge is a proximal end (393), while the end of the mounting surface (39) which is far away from the cartridge is a distal end (394), the mounting surface (39) extends from the proximal end (393) to the distal end (394) and the distal end (394) is higher than the proximal end (393) in the vertical direction. There is a mounting space (395) below the mounting surface (39) in the vertical direction, the cartridge is provided with an engagement portion (233), the engagement portion (233) is disposed opposite the mounting space (395), and the engagement portion (233) is snap-fit in the mounting space (395). The snap-fit cartridge can ensure the cartridge to still be able to be fixed stably in the mounting portion after use for a long time.

INK CARTRIDGE CHIP, INK CARTRIDGE AND INK-JET PRINTER

Disclosed are an ink cartridge chip, and an ink cartridge provided with the chip and an ink-jet printer. The ink cartridge chip (1) is used for being electrically connected to a plurality of contact probes (7) inside an ink-jet printer mounting part. The ink cartridge chip is provided with a receiving groove (2). At least two internal contact parts (201) for making contact with the contact probes are provided in the receiving groove. Providing the receiving groove that can receive the contact probes on the ink cartridge chip prevents the poor contact of the chip and the damage and bending of the contact probes caused by the probes failing to slide into a recess when the chip shifts during the mounting process of the ink cartridge chip, thus ensuring stable and effective contact between the ink cartridge chip and the contact probes, and thereby improving the stability and reliability of the use of the ink cartridge chip.

INK CARTRIDGE FOR INKJET PRINTER

Disclosed is an ink cartridge (1) for an inkjet printer that is detachably mounted in a cartridge mounting part (100) of the inkjet printer, a protruding part (104) being provided in the cartridge mounting part (100) of the inkjet printer. The ink cartridge (1) comprises an ink storage cavity (11); an ink supply port (14); a first detection mechanism (21), wherein when the ink cartridge (1) is loaded into the cartridge mounting part (100), the first detection mechanism (21) shields light emitted by a first sensor (101) of the inkjet printer or alters the path of the light emitted by the first sensor (101); a movable member (30) pushed and moved by the protruding part (104) of the inkjet printer in the process of mounting the ink cartridge (1) in the cartridge mounting part (100) of the inkjet printer; a second detection mechanism (40) linked with the movable member (30), optionally shielding light emitted by a second sensor (102) of the inkjet printer or altering the path of the light emitted ...
