Specifically, in the present embodiment, the lock structure 25 is a lock post 256 that protrudes in the + Z direction on the upper surface c of the cartridge body 21, the lock post 256 is provided at the intersection between the ink amount detection portion 23 and the light shielding portion 24, and a third protrusion 257 is provided at the upper end of the lock post 256, the third protrusion 257 is a protrusion that protrudes in the Y direction toward the left surface e or the right surface f of the cartridge body 21 on one side in the Y direction of the lock post 256, and two lock posts 256 are provided, the protrusions of the two lock posts 256 protrude toward both sides of the cartridge body 21, respectively, so that both sides above the cartridge body 21 have protrusions that can be engaged in the mounting chamber 11, and the slope at which the protrusion is connected to the lock post 256 is the first lock surface 253.

Further, the locking portion 13 is a position limiting plate provided in the mounting chamber 11 in the X direction, the upper surface of the position limiting plate in the Z direction is the second locking surface 131, when the ink cartridge 2 is mounted in the mounting chamber 11, the locking structure 25 slides above the position limiting plate by the protrusion, the first locking surface 253 is located above the second locking surface 131 in the Z direction, and the first locking surface 253 is attached to the second locking surface 131, the locking portion 13 limits the locking structure 25 in the Z direction, and the first locking surface 253 is attached to the second locking surface 131 in the Z direction, so that the position limiting plate can push against the locking structure 25, and the ink cartridge 2 can move again.

In this embodiment, other components and operation principles of the ink cartridge 2 are the same as those in the first embodiment, and will not be described here.

The utility model discloses ink horn through setting up ink horn locking structure at the ink horn upper surface, sets up between front surface and china ink volume detection portion on ink horn installation direction, and locking structure is when the installation of installation cavity is fixed, because locking structure and chip distance become nearly for the precision of chip fixed position improves, and still adopts the mode of pressing down and taking out, caters to user's use habit, ensures that the user uses the impression.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
