Description

Technical Field

[0001] The utility model relates to the technical field of printing consumables, in particular to an ink cartridge. Background Art

[0002] There is a type of ink bag type ink cartridge, which comprises two parts, a detachably connected ink storage part and a connecting part, wherein the connecting part is reusable. This type of ink cartridge needs to be loaded into a top open supporting part and then loaded into the installation part of the printer together with the supporting part.

[0003] In order to reuse the connecting part, it is necessary to replace the ink cartridge in a mode of replacing only the ink storage part. The existing structure of such ink cartridges determines that in most cases the above mode involves taking out and putting back the connecting part from the supporting part. Since the structure for positioning and matching with the supporting part on such ink cartridges is set on the connecting part, the alignment between the connecting part and the supporting part must be ensured each time the connecting part is installed into the supporting part, and a high alignment accuracy is required, so it is inconvenient to replace the ink cartridge. Some existing ink cartridge structure solutions can theoretically realize the disassembly of the ink cartridge in the supporting part, so there is no need to take out and put back the connecting part from the supporting part, but the related disassembly operation is very inconvenient to perform.

[0039] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference Figure 1 As shown, the installation part 70 of the printer includes an ink supply part 71, a fixed bracket 72, a locking part 73 and two first positioning parts 74, the fixed bracket 72 includes an electrical connection part 75, the ink supply part 71 is arranged on the surface of the fixed bracket 72 in the direction opposite to the installation direction of the ink cartridge (i.e., the second direction D2), the electrical connection part 75 can be movably arranged on the surface of the fixed bracket 72 in the direction opposite to the installation direction of the ink cartridge (i.e., the second direction D2), and the electrical connection part 75 is located in the +D3 direction of the ink supply part 71.

[0041] Reference Figure 2 as well as Figure 3As shown, the utility model provides an ink cartridge, which can be detachably arranged in a supporting member 10 of a mounting portion 70, the supporting member 10 is open on the first direction D1 side, the supporting member 10 includes a accommodating chamber 11, and after the ink cartridge is installed on the supporting member 10, a combination is formed, and the combination is inserted into the mounting portion 70 in the opposite direction of the second direction D2, and the direction in which the combination is moved out of the mounting portion 70 is the second direction D2. The supporting member 10 is basically in the shape of a rectangular parallelepiped with an opening, and the supporting member 10 has a first wall 13, a second wall 14, a bottom wall 15, an opening 12, a first side wall 16 and a second side wall 17. The opening 12 is located on the first direction D1 side of the bottom wall 15, the second wall 14 is located on the second direction D2 side of the first wall 13, and the first side wall 16 and the second side wall 17 are arranged along the third direction D3. The first wall 13 is the surface on the front end side of the insertion direction.

[0042] The support member 10 further includes a fixing structure 18 and a second positioning portion 19. Two second positioning portions 19 are provided on the first surface 13. The second positioning portions 19 may be holes. The fixing structure 18 may be a slot structure. A meandering channel is formed in the slot structure. An entrance of the slot structure is provided on the first wall 13. The locking portion 73 enters from the entrance and moves along the meandering channel to a locking position. When the support member 10 is mounted on the mounting portion 70, the second positioning portion 19 is combined with the first positioning portion 74 to locate the approximate position of the support member 10 in a direction perpendicular to the insertion direction. The fixing structure 18 is combined with the locking portion 73 to prevent the support member 10 from being separated from the mounting portion 70.

[0043] Reference Figures 2 to 9 As shown, the ink cartridge of the present application includes a connecting member 20, an ink storage member 30, a first limiting structure 40, a second limiting structure 50 and an ejecting member 60, wherein:

[0044] The connecting member 20 and the ink storage member 30 are both installed in the supporting member 10. As the supporting member 10 is installed or removed from the mounting portion 70, the ink cartridge and the printer are installed and removed. The supporting member 10 can be installed in the mounting portion 70 in the opposite direction of the second direction D2. The direction in which the supporting member 10 is removed from the mounting portion 70 is the second direction D2.

[0045] The connector 20 is at least partially accommodated in the accommodating chamber 11. The connector 20 is located at the front end of the ink cartridge in the insertion direction. The connector 20 includes a front end face 22 located on the insertion direction side (a face facing the opposite direction of the second direction D2) and an upper end face 23 (a face facing the first direction D1) intersecting the front end face 22. The connector 20 also includes an ink outlet 24, which is connected to the ink storage member 30 and is used to combine with the ink supply portion 71 to supply the ink in the ink storage member 30 to the printer. The ink outlet 24 is set through the front end face 22 of the connector 20, and the ink outlet 24 is located at a substantially middle position of the connector 20 in the third direction D3. The connector 20 also includes a mounting groove 25 that penetrates the upper end face 23 and the front end face 22, and a chip 26 is arranged in the mounting groove 25. The mounting groove 25 is located on the -D3 direction side of the ink outlet 24. The chip 26 is obliquely arranged in the mounting groove 25, and the plane where the chip 26 is located intersects both the upper end face 23 and the front end face 22. The edge of the chip 26 in the insertion direction is the front edge, which is also the lower edge of the chip 26, that is, the position of the front edge of the chip 26 in the first direction D1 is lower than the rear edge of the chip 26 (the edge of the chip 26 in the opposite insertion direction is also the upper edge of the chip 26), and the front edge of the chip 26 does not protrude from the front end surface 22 of the connector 20 in the insertion direction. When the ink cartridge is installed in the installation portion 70, the chip can contact the electrical connection portion 75 to form an electrical connection.

[0046] The ink storage component 30 is at least partially accommodated in the accommodating cavity 11. The ink storage component 30 is installed in the supporting component 10 through the opening 12, and is detachably connected to the connecting component 20. When the ink storage component 30 needs to be replaced, the connection between the ink storage component 30 and the connecting component 20 is released, and the ink storage component 30 can be removed to achieve replacement, without separating the connecting component 20 from the supporting component 10 and then installing it.

[0047] Reference Figure 4 , Figure 5 , Figure 6 as well as Figure 8 As shown, the first limiting structure 40 is used to limit the relative movement of the ink storage member 30 and the connecting member 20 in the first direction D1. The first direction D1 is the direction of gravity upward. When the ink storage member 30 is connected to the connecting member 20, the first limiting structure 40 prevents the ink storage member 30 from moving upward, thereby ensuring the stability of the connection between the ink storage member 30 and the connecting member 20. When the ink storage member 30 needs to be replaced, the restriction of the first limiting structure 40 on the ink storage member 30 is released, so that it can move upward along the first direction D1 and separate from the connecting member 20.

[0048] The second limiting structure 50 is used to limit the relative movement of the ink storage member 30 and the connecting member 20 in the second direction D2. The second direction D2 is the opposite direction of the installation direction, that is, the direction in which the ink cartridge moves away from the installation portion 70. When the ink cartridge is installed in the installation portion 70, under the action of the second limiting structure 50, the ink storage member 30 can be prevented from moving in the direction away from the connecting member 20, that is, the separation of the ink storage member 30 and the connecting member 20 in the second direction D2 is prevented, which is beneficial to improving the connection strength between the ink storage member 30 and the connecting member 20, thereby ensuring the normal operation of the ink cartridge in the installation portion 70.

[0049] The ejector 60 can be elastically deformed along the first direction D1, and the opposite ends of the ejector 60 are respectively abutted against the connecting member 20 and the ink storage member 30. During the abutment process, the ejector 60 accumulates elastic force. When the first limiting structure 40 releases the restriction on the ink storage member 30, the elastic force accumulated by the ejector 60 acts on the ink storage member 30, so that the ink storage member 30 can be elastically moved along the first direction D1, thereby achieving separation from the connecting member 20.

[0050] In the present application, the first limiting structure 40 and the second limiting structure 50 work together to enable the connecting member 20 and the ink storage member 30 to be stably connected in the supporting member 10, and the connecting member 20 is always fixed in the supporting member 10, so that the connecting member 20 and the supporting member 10 form a transition body. When the ink in the ink storage member 30 is used up, it is only necessary to remove the old ink storage member 30 and replace it with a new ink storage member 30, without removing the connecting member 20 from the supporting member 10 and then installing it back. The operation is simple and the replacement efficiency of the ink cartridge is effectively improved.

[0051] In the embodiment provided in the present application, the first limiting structure 40 includes a first limiting member and a second limiting member. The first limiting member can move back and forth along a third direction D3. The third direction D3 is a horizontal direction that is orthogonal to the first direction D1 and the second direction D2, respectively. When the ink storage member 30 is connected to the connecting member 20, the first limiting member and the second limiting member are engaged to fix the position of the ink storage member 30 and the connecting member 20, thereby limiting the movement of the ink storage member 30 along the first direction D1.

[0052] In a feasible implementation mode, referring to Figure 8As shown, the first limiting member includes at least two elastic clips 41, preferably two elastic clips 41, the two elastic clips 41 are arranged opposite to each other along the third direction D3, and can move along the third direction D3 at the same time. When one of the elastic clips 41 moves along the +D3 direction, the other elastic clip 41 moves along the -D3 direction, so that the two elastic clips 41 are close to each other or away from each other. Each elastic clip 41 is provided with a limiting protrusion 42, and the second limiting member is a side abutment 43 that can cooperate with the limiting protrusion 42. The number and position of the side abutment 43 are adapted to the number and position of the limiting protrusion 42, preferably two, and the projection of each limiting protrusion 42 in the opposite direction of the first direction D1 at least partially falls on the corresponding side abutment 43, so that the limiting protrusion 42 and the corresponding side abutment 43 form a limiting match in the first direction D1, thereby limiting the ink storage member 30 from moving in the first direction D1. Through the cooperation of a plurality of elastic clips 41 and a corresponding number of side abutments 43, the limiting effect of the first limiting structure 40 on the ink storage member 30 can be improved, and the connection between the ink storage member 30 and the connecting member 20 can be made more stable.

[0053] The first limiting member can be arranged on the connecting member 20 or the ink storage member 30, and the second limiting member is correspondingly arranged on the ink storage member 30 or the connecting member 20. When the two elastic clips 41 are arranged on the connecting member 20, the side abutment 43 is arranged on the ink storage member 30, and the two elastic clips 41 are arranged opposite to each other. The opposite sides of the two elastic clips 41 are provided with limiting protrusions 42, and the two side abutment portions 43 correspond to the two limiting protrusions 42 respectively. When the ink storage member 30 is connected to the connecting member 20, the limiting The protrusion 42 abuts against the corresponding side abutment 43 to limit the separation of the ink storage component 30 and the connecting component 20. When the ink storage component 30 needs to be replaced, the two elastic clips 41 are moved in the +D3 direction and the -D3 direction respectively to move the two elastic clips 41 away from each other, thereby releasing the limiting cooperation between the limiting protrusion 42 and the corresponding side abutment 43, and under the action of the ejection component 60, the ink storage component 30 is prompted to move along the first direction D1, thereby realizing the separation of the ink storage component 30 and the connecting component 20.

[0054] When the two elastic clips 41 are arranged on the ink storage member 30, the two side abutments 43 are arranged on the connecting member 20, and the two opposite side surfaces of the two elastic clips 41 are provided with limiting protrusions 42, and the two side abutments 43 are respectively arranged at positions on the connecting member 20 corresponding to the two limiting protrusions 42. When the ink storage member 30 is connected to the connecting member 20, the limiting protrusions 42 abut against the corresponding side abutments 43. When the ink storage member 30 needs to be replaced, the two elastic clips 41 are moved along the +D3 direction and the -D3 direction respectively, so that the spacing between the two elastic clips 41 in the third direction D3 becomes larger, and the limiting protrusions 42 on the elastic clips 41 are respectively released from the limiting relationship with the corresponding side abutments 43, and the ink storage member 30 moves along the first direction D1 under the action of the ejection member 60, thereby realizing the separation of the ink storage member 30 and the connecting member 20. No matter whether the elastic clip 41 is arranged on the ink storage member 30 or the connecting member 20 , when separating the ink storage member 30 from the connecting member 20 , it can be realized by one-handed operation, which is convenient and quick.

[0055] Furthermore, in the first direction D1, the side abutment portion 43 is arranged in the middle section of the corresponding elastic clip 41, and the limiting protrusion 42 is arranged at the corresponding position of the middle section of the elastic clip 41. On the one hand, it is convenient to move the elastic clip 41, and on the other hand, it can enhance the limiting cooperation between the side abutment portion 43 and the limiting protrusion 42, which is beneficial to improve the effect of the first limiting structure 40 in limiting the movement of the ink storage member 30 along the first direction D1, thereby ensuring the stability and reliability of the connection between the ink storage member 30 and the connecting member 20, and further ensuring that the ink cartridge in the installation portion 70 can normally supply ink to the printer.

[0056] In order to more conveniently separate the elastic clip 41 from the side support portion 43, an extension portion 411 is provided at one end of the elastic clip 41 in the first direction D1, that is, the extension portion 411 is provided at the top of the elastic clip 41, and there is a preset angle between the extension direction of the extension portion 411 and the first direction D1, so that the extension portion 411 is provided at the top of the elastic clip 41 in an inclined state. In a feasible embodiment, the extension portion 411 includes a first end and a second end, and the first end is connected to the top of the elastic clip 41. In order to facilitate the operator to open the elastic clip 41 through the extension portion 411, the spacing between the first ends of the two extension portions 411 is smaller than the spacing between the second ends of the two extension portions 411, so that the second ends of the two extension portions 411 are inclinedly provided at the top of the corresponding elastic clip 41 in a state of being away from each other.

[0057] When separating the ink storage component 30 and the connecting component 20, the operator only needs to push the elastic clips 41 apart through the two extension parts 411 to move the two elastic clips 41 in opposite directions, specifically, move one of the two corresponding elastic clips 41 in the +D3 direction, and move the other in the -D3 direction, so that the distance between the two elastic clips 41 becomes larger, thereby separating the limiting protrusion 42 from the corresponding side abutment part 43, and releasing the limiting cooperation between the two.

[0058] Reference Figure 4 , Figure 5 , Figure 8 as well as Fig. 9 As shown, in the embodiment provided by the present application, the connecting member 20 includes a receiving portion 21, and the ink storage member 30 includes a lead-out portion 31, the lead-out portion 31 is at least partially located in the receiving portion 21, the lead-out portion 31 is connected to the ink outlet 24, and the ink in the ink storage member 30 enters the ink supply portion 71 from the ink outlet 24 through the lead-out portion 31, thereby providing ink for the printer. The fixed connection between the ink storage member 30 and the connecting member 20 can be achieved by the fixed connection between the lead-out portion 31 and the receiving portion 21, so that two elastic clips 41 are arranged on the opposite inner wall surfaces of the receiving portion 21, the limiting protrusions 42 are respectively arranged on the opposite sides of the two elastic clips 41, the lead-out portion 31 is located between the two elastic clips 41, and the two side abutments 43 are arranged on the opposite sides of the lead-out portion 31 in the third direction D3, and correspond to the positions of the two limiting protrusions 42. When the two limiting protrusions 42 are respectively abutted against the corresponding side abutment portions 43, the lead-out portion 31 is fixed in the accommodating portion 21. When the two elastic clips 41 are pushed away from each other along the third direction D3, the limiting protrusions 42 and the corresponding side abutment portions 43 are released from the abutment state. Under the action of the elastic force of the ejection member 60, the lead-out portion 31 is ejected out of the accommodating portion 21, thereby realizing the separation of the ink storage member 30 and the connecting member 20.

[0059] Preferably, the side abutment portion 43 includes a first protrusion, which is arranged on opposite sides of the lead-out portion 31 in the third direction D3. The two first protrusions 431 extend from the surface of the lead-out portion 31 along the +D3 direction and the -D3 direction respectively. In the first direction D1, there is an overlapping portion between each first protrusion 431 and the corresponding limiting protrusion 42, thereby ensuring that the limiting protrusion 42 can abut against the first protrusion 431 to form a limiting fit.

[0060] In other embodiments, the first limiting structure 40 may adopt other structures or components that can limit the movement of the ink storage portion in the first direction D1, which is not limited here.

[0061] After the ink storage member 30 and the connecting member 20 are fixedly connected under the action of the first limiting structure 40, in order to ensure that the ink storage member 30 can stably supply ink in the mounting portion 70, the movement of the ink storage member 30 in the second direction D2 should be limited to ensure that the ink storage member 30 cannot be separated from the connecting member 20 in the second direction D2. In the embodiment provided in the present application, the second limiting structure 50 includes a third limiting member and a fourth limiting member, and the projection of the third limiting member in the second direction D2 at least partially falls on the fourth limiting member, so that a limiting fit in the second direction D2 can be formed between the third limiting member and the fourth limiting member, so as to fix the positions of the ink storage member 30 and the connecting member 20 in the second direction D2, thereby ensuring the stability of the connection between the ink storage member 30 and the connecting member 20 in the second direction D2.

[0062] In a feasible implementation mode, referring to Figure 4 , Figure 5 as well as Figure 7 As shown, the third limiting member includes a second protrusion 51, and the second protrusion 51 is arranged on the opposite sides of the outlet portion 31 in the third direction D3. The two second protrusions 51 extend on the surface of the outlet portion 31 along the +D3 direction and the -D3 direction respectively. The fourth limiting member is a front abutment 52 that can abut against the second protrusion 51. The front abutment 52 is the side of the elastic clip 41 opposite to the second direction D2, and the second protrusion 51 is located at a position of the front abutment 52 in the opposite direction to the second direction D2. When the outlet portion 31 is installed in the accommodating portion 21, the front abutment 52 abuts against the second protrusion 51 to form a limiting fit to limit the movement of the ink storage component 30 in the second direction D2, thereby realizing the second limiting structure 50 to limit the separation of the ink storage component 30 and the connecting component 20 in the second direction D2.

[0063] In other embodiments, the second limiting structure 50 may adopt other structures or components that can limit the movement of the ink storage member 30 in the second direction D2, which is not limited here.

[0064] Reference Figure 8 as well as Fig. 9 As shown, the accommodating portion 21 further includes a positioning groove 211, which is used to accommodate the ejector 60. The positioning groove 211 is a groove formed by the surface of the accommodating portion 21 being recessed in the opposite direction of the first direction D1. One end of the ejector 60 abuts against the bottom wall of the positioning groove 211, and the other end abuts against the ink storage member 30. When the ink storage member 30 and the connecting member 20 are fixed in position, the ejector 60 accumulates elastic force. When the first limiting structure 40 releases the limiting effect on the movement of the ink storage member 30, the ejector 60 applies the accumulated elastic force to the ink storage member 30, and lifts the ink storage member 30 along the first direction D1, so as to separate the ink storage member 30 from the connecting member 20.

[0065] In a feasible embodiment, the ejector 60 is a spring, one end of the spring abuts against the bottom wall of the positioning groove 211, and the other end of the spring abuts against the lead-out portion 31. When the lead-out portion 31 is fixed in the accommodating portion 21, the spring is compressed and accumulates elastic force. When the limiting relationship between the lead-out portion 31 and the accommodating portion 21 is released, the spring elastically deforms and elongates along the first direction D1, and the accumulated elastic force acts on the lead-out portion 31, so that the lead-out portion 31 is ejected from the accommodating portion 21, thereby realizing the separation of the lead-out portion 31 from the accommodating portion 21.

[0066] In other embodiments, the ejector 60 may adopt other structures or components capable of elastic deformation, which is not limited here.

[0067] Based on the above embodiments, the process of replacing the ink storage member 30 of the ink cartridge of the present application and installing it on the installation portion 70 is as follows:

[0068] The two elastic clips 41 are pushed apart, so that the limiting protrusions 42 and the corresponding side abutment portions 43 are separated from each other, and the restriction of the first limiting structure 40 on the ink storage member 30 is released. Under the elastic force of the ejector 60, the ink storage member 30 is urged to move along the first direction D1, and then separated from the connecting member 20. Then, a new ink storage member 30 is installed in the supporting member 10, so that the limiting protrusions 42 on the elastic clips 41 and the corresponding side abutment portions 43 abut against each other to form a limiting fit in the first direction D1. At the same time, the second protrusions 51 and the front abutment portions 52 abut against each other to form a limiting fit in the second direction D2, so that the fixing of the ink storage member 30 and the connecting member 20 is completed. Then, the supporting member 10 is installed in the mounting portion 70 along the mounting direction, and the connecting member 20 and the ink storage member 30 are installed in the mounting portion 70 together with the supporting member 10, and the connection between the ink cartridge and the mounting portion 70 is completed. During the process of replacing the ink storage member 30 , the connecting member 20 is always located in the supporting member 10 , and there is no need to remove and then install the connecting member 20 .
