In one possible embodiment, the positioning columns 31 and the positioning sleeves 32 each include two positioning columns 31 and 32, the two positioning columns 31 are disposed in the accommodating groove 21, the positioning columns 31 extend from the bottom wall of the accommodating groove 21 along the second direction D2, the two positioning columns 31 are disposed on opposite sides of the main body 1111 along the third direction D3, the main body 1111 includes a pipe member 11111 and a plate member 11112, the plate member 11112 includes two plate members 11112 disposed on opposite sides of the pipe member 11111 along the third direction D3, the two positioning sleeves 32 are respectively disposed on the two plate members 11112 in a penetrating manner, and positions of the two positioning columns 31 in the accommodating groove 21 correspond to the two positioning sleeves 32. When the connecting piece 20 is connected with the ink storage piece 10, the main body 1111 needs to be placed in the accommodating groove 21, so that the positioning sleeves 32 on the two plate members 11112 are sleeved on the corresponding positioning posts 31, and the positioning posts 31 and the corresponding positioning sleeves 32 form a limit fit, so that the joint 111 and the connecting piece 20 are limited to move relatively in the first direction D1. The tube member 11111 is further provided with a discharge passage 11114, and the discharge passage 11114 communicates with the ink bag 12, so that when the ink cartridge 100 is mounted on the mounting portion 60, ink in the ink bag 12 can flow from the discharge passage 11114 into the ink supply portion 61.
Further, in order to prevent the tube member 11111 from being deviated or deflected in the third direction D3, referring to fig. 4 and 7, the tube member 11111 includes a positioning protrusion 11113, the positioning protrusion 11113 is disposed on one side of the tube member 11111 near the accommodating groove 21, the positioning protrusion 11113 is a protrusion disposed on the opposite side of the tube member 11111 in the second direction D2 and extending along the first direction D1, a rotation stopping portion 211 is disposed in the accommodating groove 21, the rotation stopping portion 211 is a rib extending along the first direction D1, and the rotation stopping portion 211 abuts against opposite sides of the positioning protrusion 11113 in the third direction D3.

Since the material of the joint 111 is inferior in mechanical properties to the material of the connector 20, the joint 111 is more easily broken and deformed with respect to the connector 20 after the joint 111 is connected with the connector 20, and in order to enhance the strength of the joint 111, in the embodiment provided by the present application, referring to fig. 7, the outer support member 1112 further includes the reinforcing ribs 11123, the reinforcing ribs 11123 are connected with the support portions 11121, and since the outer support member 1112 includes two, both support portions 11121 have one reinforcing rib 11123 connected thereto, and two reinforcing ribs 11123 are provided on opposite sides of the pipe member 11111 in the third direction D3 and on opposite sides of the corresponding plate member 11112 in the second direction D2, respectively, to reinforce the corresponding support portions 11121, thereby enhancing the strength of the joint 111.
Referring to fig. 4 to 7, in the embodiment provided by the application, the second limiting structure 40 includes two first protrusions 41 and two second protrusions 42, the first protrusions 41 include two first protrusions 41 disposed on opposite sidewalls of the accommodating groove 21 in the third direction D3, each first protrusion 41 may abut against the corresponding side abutment 11122, when the engaging portion 111 receives an external force, the external force may be transferred to the first protrusions 41 through the side abutment 11122, and the first protrusions 41 may support the side abutment 11122 in the third direction D3 to overcome the action of the external force on the side abutment 11122, thereby avoiding the side abutment 11122 from being offset in the third direction D3.
The second protrusions 42 include two second protrusions 42, where the two second protrusions 42 are respectively disposed on one side of the side abutting portion 11122 facing the corresponding first protrusion 41, the first protrusion 41 is disposed on the second direction D2 side of the second protrusion 42, referring to fig. 5, the first protrusion 41 is located below the second protrusion 42, and in the second direction D2, the projection of the second protrusion 42 at least partially falls on the first protrusion 41, so that the second protrusion 42 can at least partially abut on the first protrusion 41, and further the relative movement between the joint portion 111 and the connecting piece 20 in the second direction D2 is limited.
In addition, the two side propping portions 11122 extend along the direction inclined relative to the second direction D2, so that the distance between the +d2 direction ends of the two side propping portions 11122 is larger than the distance between the-D2 direction ends of the two side propping portions 11122, and it can be ensured that the two side propping portions 11122 are propped against the corresponding first protrusions 41 in the third direction D3 in the non-mounting state, and meanwhile, the two second protrusions 42 are respectively propped against the corresponding first protrusions 41 in the second direction D2. In the mounted state, the two side abutting portions 11122 have larger deformation amounts relative to the non-mounted state, so that the guiding-out part 11 and the connecting piece 20 are more tightly matched in the third direction D3, and the deviation of the joint portion 111 in the third direction D3 is more favorably restrained.
Because the ink cartridge 100 of the present application has an ink bag type structure, as the ink cartridge 100 continuously supplies ink to the ink supply portion 61, the ink bag 12 is irregularly collapsed due to the reduced amount of ink, and a dead zone which is not communicated with the outlet channel 11114 occurs, so that ink cannot smoothly flow out from the outlet channel.
