Detailed implementation manners

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] First Embodiment:

[0033] Refer to Figures 1 to 4 As shown, an ink cartridge includes a cartridge body 10, a handle 11, and an ink cartridge chip 12. The cartridge body 10 stores a developing medium. The handle 11 is provided on one side of the cartridge body 10 and can rotate relative to the cartridge body 10 about the X-axis. That is, when the handle 11 is pressed, it can rotate towards the direction close to the cartridge body 10 to reduce the pressure it receives, avoiding the problem of plastic deformation or even fracture of the handle 11 due to long-term pressure. The ink cartridge chip 12 is installed on the cartridge body 10 and is arranged on the same side as the handle 11. The ink cartridge chip 12 is located below the handle 11. After the ink cartridge is installed on the print carriage 20, the ink cartridge chip 12 is in contact connection with the contact pin 22 on the print carriage 20, so that the printing device can read the information of the ink cartridge. A first limiting structure 111 is provided on the handle 11, and a first limiting rib 24 extending in the Z direction is provided on the print carriage 20. The ink cartridge is installed on the print carriage 20 from top to bottom in the Z direction. After installation, the first limiting structure 111 is located on the side of the first limiting rib 24 away from the ink cartridge. That is, the first limiting rib 24 and the first limiting structure 111 cooperate to limit the ink cartridge from moving away from the print carriage 20 in the Y direction, thus avoiding the problem of poor contact between the ink cartridge chip 12 and the contact pin 22 of the print carriage 20.

[0034] In some possible ways, the handle 11 and the cartridge body 10 are integrally formed. The connection part 113 between the handle 11 and the cartridge body 10 can be in the shape of a sheet or the thickness dimension of the connection part 113 is smaller than the thickness dimension of the handle 11. It can also be that at least one crease line is formed on the connection part 113. When the handle 11 is pressed, it can rotate relative to the cartridge body 10 about the X-axis and retract towards the cartridge body 10 with the connection part 113 or the crease line on the connection part 113 as the rotation center, thus avoiding the problem of plastic deformation or fracture of the handle 11 due to long-term pressure. And the design of the connection part 113 can reduce the rigidity and the resistance to deformation at this part, avoiding the problem of fracture at this part when the handle 11 is pressed.

[0035] In some possible ways, a second limiting rib 101 extending in the Z direction is provided on the cartridge body 10. An activity space 102 is formed between the second limiting rib 101 and the side surface of the cartridge body 10, that is, the second limiting rib 101 extends a certain distance in the Y direction from the side surface of the cartridge body 10 to form the activity space 102. A second limiting structure 112 is provided on the handle 11. After the handle 11 is connected to the cartridge body 10, the second limiting structure 112 is located in the activity space 102, and the amplitude of the rotation of the handle 11 relative to the cartridge body 10 is the amplitude of the swing of the second limiting structure 112 in the activity space 102. In this application, the second limiting rib 101 is used to limit the second limiting structure 112 from moving in the Y direction towards the direction close to the printing carriage 20, so as to avoid the problem that the first limiting structure 111 and the first limiting rib 24 cannot be accurately aligned during the installation of the ink cartridge, and at the same time avoid the problem that the handle 11 and the cartridge body 10 are easily separated when they are of a split design.

[0036] Further, two connecting portions 103 both protruding in the X direction are formed on the side surface of the cartridge body 10. The second limiting rib 101 is formed at the front end of the connecting portion 103 and extends in the Y direction towards the inner side of the connecting portion 103. At this time, the above-mentioned activity space 102 is the area enclosed by the side surface of the cartridge body 10, the inner sides of the two connecting portions 103, and the two second limiting ribs 101. The height of the connecting portion 103 protruding from the side surface of the cartridge body 10 is related to the swing amplitude of the second limiting structure 112 in the activity space 102. When the handle 11 is pressed, it can rotate around the X axis until the second limiting structure 112 abuts against the side surface of the cartridge body 10. In the natural state, the handle 11 can also rotate around the X axis until the second limiting structure 112 abuts against the second limiting rib 101 but cannot make the second limiting structure 112 cross the second limiting rib 101, so as to ensure the correct connection between the handle 11 and the cartridge body 10 and facilitate the storage and packaging of the handle 11 with the cartridge body 10.

[0037] Furthermore, a first guiding inclined opening portion 104 is formed on the side of the second limiting rib 101 away from the cartridge body 10. The second limiting structure 112 is rod-shaped and the second limiting structure 112 extends in the X direction at the lower end of the handle 11. A second guiding inclined opening portion 114 is also provided on the side of the second limiting structure 112 close to the second limiting rib 101. The first guiding inclined opening portion 104 and the second guiding inclined opening portion 114 cooperate with each other, so that during assembly, the second limiting structure 112 can rotate relative to the cartridge body 10 along with the handle 11 and cross the second limiting rib 101, so that the second limiting structure 112 is restricted in the activity space 102.

[0038] In some possible ways, the first limiting structure 111 is arranged on opposite sides of the handle 11 and below the second limiting structure 112. The first limiting structure 111 can be in the shape of a sheet or a block, so that after the ink cartridge is installed on the print head carriage 20, the first limiting structure 111 is blocked by the first limiting rib 24, preventing the ink cartridge from moving away from the print head carriage 20 in the Y direction and causing poor contact between the ink cartridge chip 12 and the contact pin 22. Further, a first buckle protrusion 115 is provided on the outer side of the handle 11, and an installation groove 21 for placing the cartridge body 10 is provided on the print head carriage 20. A second buckle protrusion 25 that cooperates with the first buckle protrusion 115 is provided at the upper end of the installation groove 21. When the ink cartridge is inserted into the installation groove 21 in the Z direction, the first buckle protrusion 115 presses against the second buckle protrusion 25 and causes the handle 11 to rotate relative to the cartridge body 10, so that the first buckle protrusion 115 can cross over the second buckle protrusion 25 until the ink cartridge is installed in place. At this time, the second buckle protrusion 25 cooperates with the first buckle protrusion 115 to limit the movement of the ink cartridge in the Z direction, and in the X direction, the limiting is achieved by the cooperation of the groove wall 23 of the installation groove 21 and the side surface of the cartridge body 10 or the side surface of the first limiting structure 111. It should be noted that the first limiting rib 24 is formed on the groove wall 23 of the installation groove 21 in the Z direction. To facilitate packaging and transportation and avoid the problem of the first limiting structure 111 being broken under pressure, it is designed that the outer side surface of the first limiting structure 111 does not protrude beyond the outer side surface of the handle 11.

[0039] Second Embodiment:

[0040] Referring to Figures 5 to 8 As shown, compared with the first embodiment, the difference of the ink cartridge in this embodiment is that: a rotation opening groove 116 is provided at a position above the ink cartridge chip 12 on the side surface of the cartridge body 10, and a rotating shaft 117 is provided at the lower end of the handle 11. The rotating shaft 117 can be inserted into the rotation opening groove 116 in the Y direction, so that the handle 11 can rotate relative to the cartridge body 10 around the rotating shaft 117, that is, the handle 11 and the cartridge body 10 are designed as a split type in this embodiment.

[0041] In some possible ways, the first limiting structure 111 is in the shape of an inverted hook. When the ink cartridge is installed into the installation groove 21 of the print head carriage 20 from top to bottom in the Z direction, the inverted hook-shaped first limiting structure 111 can be hooked on the upper end of the first limiting rib 24.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
