[0053] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0054] In the related art, in order to improve the scope of application of the recycling and reuse of original ink cartridges, the claws on the side of the original ink cartridges need to be reprocessed when the original ink cartridges are recycled and reused. Specifically, a part of the claws on the side of the original ink cartridges needs to be milled off. Because the claws play the role of positioning the ink cartridge installation, the dimensional accuracy of the claws is required to be high. In actual production, it is difficult to ensure the production accuracy of the claws, and it is difficult to ensure the consistency of the size of the claws on both sides. In addition, after a part of the claws is milled off, the strength becomes weaker and there is a problem of easy breakage, resulting in a high production defect rate.

[0055] In view of this, the present invention provides a recycled ink cartridge, wherein positioning structures are provided on the opposite side walls of the mounting plate, and the mounting plate is provided on the mounting surface of the cartridge body. The positioning structures are used to guide the recycled ink cartridge when it is installed in the mounting cavity, and to position the recycled ink cartridge after it is installed in place, thereby improving the installation accuracy of the recycled ink cartridge and helping to limit the movement of the recycled ink cartridge in the mounting cavity, thereby ensuring that after the recycled ink cartridge is installed in the printer, the ink outlet provided on the cartridge body can be accurately docked with the ink supply needle of the printer to ensure the ink supply effect. When the original ink cartridge is recycled and reused, the claws on the side of the original ink cartridge are completely cut off, thereby avoiding problems such as weakening of the claw strength and breakage caused by milling off a part of the claw.

[0056] The following describes the recycling ink cartridge provided by the embodiment of the present invention with reference to the accompanying drawings.

[0057] refer to Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a recycling ink cartridge, which can be detachably installed in the installation cavity of the printer. The recycling ink cartridge includes: a cartridge body 10, a mounting plate 20 and a chip assembly 30. The cartridge body 10 has a accommodating cavity 11 for accommodating ink, and the outer wall of the front end of the cartridge body 10 is a mounting surface 12; the mounting plate 20 is arranged on the mounting surface 12, and positioning structures 21 are provided on the opposite side walls of the mounting plate 20. The positioning structures 21 protrude from the outer side walls of the mounting plate 20, and are used to guide the recycling ink cartridge into the installation cavity of the printer and position the recycling ink cartridge in the installation cavity; the chip assembly 30 is arranged on the side of the mounting plate 20 facing away from the cartridge body 10.

[0058] The utility model provides a recycling ink cartridge, in which positioning structures 21 are provided on the opposite side walls of the mounting plate 20. The positioning structures 21 are used to play a guiding role when the recycling ink cartridge is installed in the mounting cavity, and to play a positioning role after the recycling ink cartridge is installed in place, thereby improving the installation accuracy of the recycling ink cartridge and helping to limit the movement of the recycling ink cartridge in the mounting cavity, thereby ensuring that after the recycling ink cartridge is installed in the printer, the ink outlet provided on the cartridge body 10 can be accurately docked with the ink supply needle of the printer, thereby ensuring the ink supply effect.

[0059] When converting the ink cartridge, the claws on the original ink cartridge are milled off and the mounting plate 20 is connected to the mounting surface 12 of the cartridge body 10 to facilitate the recovery of the ink cartridge for displacement. Figure 3 and Figure 4 As shown, after the ink cartridge is converted, the position of the nozzle 16 is aligned with the original ink cartridge. The positioning structure 21 provided on the opposite side walls of the mounting plate 20 is used to meet the positioning requirements of the ink cartridge after displacement.

[0060] The utility model provides a recycled ink cartridge. When converting the ink cartridge into production, the entire clamping claw on the original ink cartridge is milled off, which can solve the problem of high processing precision and difficult operation of the positioning structure 21 when converting the original ink cartridge across generations, reduce the problem of breakage of the positioning structure 21, and reduce the production defect rate.

[0061] The utility model provides a recycling ink cartridge. Since the positioning structure 21 is arranged on the opposite side walls of the mounting plate 20, the positioning structure 21 can be an integral structure formed integrally with the mounting plate 20, which simplifies the processing process and does not require milling processing on the positioning structure 21, preventing the operation of milling off the claws from weakening the strength of the positioning structure 21 itself, and helps to reduce the problem of breakage and damage of the positioning structure 21 affecting positioning.

[0062] In one possible implementation, reference Figure 3 and Figure 4 As shown, the box body 10 includes a bottom shell 17 and an upper cover 18, and the bottom shell 17 and the upper cover 18 surround a receiving chamber 11. A liquid absorber 19 is provided in the receiving chamber 11, and the liquid absorber 19 is used to absorb and store ink.

[0063] In one possible implementation, the height of the cartridge body 10 may be 37 mm to 45 mm. The cartridge body 10 having this height can be installed in printers with installation cavities of different sizes, thereby increasing the applicability of the recycled ink cartridge.

[0064] In one possible implementation, reference Figure 2 and Figure 3As shown, the upper cover 18 has a latching portion 181 on its side facing away from the bottom shell 17. This latching portion 181 is used to secure the top end of the recycled ink cartridge to the printer's mounting cavity. Positioning structures 21 are provided on opposing side walls of the mounting plate 20 to secure the side surfaces of the recycled ink cartridge to the printer's mounting cavity, improving the stability of the cartridge's mounting position.

[0065] In one possible implementation, the clamping portion 181 and the upper cover 18 can be integrally formed, that is, a unitary structure. The number of the clamping portions 181 can be one or two spaced apart. The lengths of the two clamping portions 181 can be the same or different.

[0066] In one possible implementation, the mounting plate 20 may be adhered to the mounting surface 12 of the cartridge body 10. Alternatively, the mounting plate 20 may be connected to the mounting surface 12 via a snap-fit ​​connection, or via fasteners such as screws. The connection method between the mounting plate 20 and the cartridge body 10 is not specifically limited herein, as long as the mounting plate 20 can be stably connected to the mounting surface 12 of the cartridge body 10. Furthermore, mounting plates 20 of varying thicknesses may be selected based on the size of the printer, thereby improving the compatibility of recycled ink cartridges with different printers and enhancing their recycling rate.

[0067] In one possible implementation, the printer includes a mounting portion, in which a mounting cavity for mounting an ink cartridge is formed. For mounting portions with different mounting cavity structures, the utility model provides a recycling ink cartridge that can be installed and matched with multiple or certain printers with different mounting portion structures by replacing a mounting plate 20 with a different positioning structure 21.

[0068] In this embodiment, the front end of the cartridge body 10 is oriented in the same direction as the installation direction of the recovery ink cartridge in the installation cavity.

[0069] In one possible implementation, chip assembly 30 includes chip 31, which has identification capabilities and communicates with the printer to transmit signals. Chip 31 is provided with a storage element that can store information such as manufacturer information, ink level information, consumable cartridge type information, and ink color. Because the ink level information is lost during the recycling process, it is not included.

[0070] In one possible implementation, the chip 31 may be rectangular or in other shapes, and the thickness of the chip 31 may be flexibly set according to usage requirements to meet the electrical connection requirements between the recycled ink cartridge and the printer.

[0071] In one possible implementation, the positioning structure 21 protrudes from the outer wall of the mounting plate 20 along a direction perpendicular to the central axis of the mounting plate 20. The central axis of the mounting plate 20 is a virtual axis passing through the center of the mounting plate 20 and perpendicular to the surface of the mounting plate 20.

[0072] In one possible implementation, the positioning structures 21 are located on two opposite side walls of the bottom end of the mounting plate 20. The positioning structures 21 provide a good positioning effect on the two sides of the recycling ink cartridge when the recycling ink cartridge is installed in the printer.

[0073] In a possible implementation, the positioning structure 21 may be a cylinder or a columnar structure having at least one flat surface 211 on its outer circumference. The axial direction of the positioning structure 21 is along a direction perpendicular to the central axis of the mounting plate 20 .

[0074] In this example, the axial direction of the positioning structure 21 is consistent with the width direction of the box body 10 .

[0075] In one possible implementation, a first fixing structure 22 is provided on a side of the mounting plate 20 facing away from the box body 10, and a second fixing structure is provided on a side of the chip assembly 30 facing the mounting plate 20. One of the first fixing structure 22 and the second fixing structure is a fixing column, and the other of the first fixing structure 22 and the second fixing structure is a fixing hole, and the fixing column extends into the fixing hole.

[0076] In a possible implementation, the first fixing structure 22 is a fixing column, and the second fixing structure is a fixing hole. The fixing column extends into the fixing hole to improve the stability of the installation and positioning of the chip assembly 30.

[0077] In a possible implementation, the first fixing structure 22 is a fixing hole, and the second fixing structure is a fixing column. The fixing column extends into the fixing hole to improve the stability of the installation and positioning of the chip assembly 30.

[0078] In a possible implementation, the number of the first fixing structures 22 may be two or three, and the number of the second fixing structures is the same as the number of the first fixing structures 22 .

[0079] In one possible implementation, a groove 23 is provided on the side of the mounting plate 20 facing away from the box body 10. The groove 23 is located above the first fixing structure 22. A wafer is provided on the side of the chip assembly 30 facing the mounting plate 20. The wafer is located in the groove 23. This structure provides a good avoidance effect for the wafer through the groove 23, thereby protecting the wafer.

[0080] In a possible implementation, the wafer is disposed on a side of the chip 31 facing the mounting board 20 .

[0081] In one possible implementation, reference Figure 1 、 Figure 5 and Figure 6 As shown, both sides of the mounting plate 20 have hooking portions 24, and both sides of the cartridge body 10 have locking protrusions 13, with the hooking portions 24 hooked on the locking protrusions 13. This improves the accuracy of the mounting position of the mounting plate 20 relative to the cartridge body 10, and provides good stability in the installation of the mounting plate 20 and the cartridge body 10, thereby ensuring the quality of the recycled ink cartridges.

[0082] In a possible implementation, the locking protrusion 13 is a protruding structure protruding from two side surfaces of the box body 10 , and the locking protrusion 13 may be located near the bottom end of the box body 10 .

[0083] In one possible implementation, reference Figure 1 and Figure 3 As shown, the hooking portion 24 includes a first section 241 and a second section 242 connected to each other. The first section 241 protrudes from the side of the mounting plate 20 facing away from the cartridge body 10 and extends obliquely toward the bottom of the cartridge body 10. Both sides of the cartridge body 10 also have a clearance groove 14, which is located below the protruding portion 13. The second section 242 extends into the clearance groove 14. The clearance groove 14 is used to avoid the second section 242, so that the two sides of the recovered ink cartridge are flat.

[0084] In one possible implementation, reference Figure 3 and Figure 5 As shown, the first end of the first section 241 is connected to the surface of the mounting plate 20, and the second end of the first section 241 is connected to the second section 242. From the first end of the first section 241 to the second end of the first section 241, the first section 241 gradually tilts away from the box body 10, that is, the height protruding from the surface of the mounting plate 20 gradually increases.

[0085] In one possible implementation, an angle is formed between the first section 241 and the second section 242, and the angle is acute. The end of the latching protrusion 13 facing the hooking portion 24 is shaped like a corner, so that the latching protrusion 13 extends toward the hooking portion 24 into the angle between the first section 241 and the second section 242, and the first section 241 and the second section 242 respectively abut against the side edges of the latching protrusion 13.

[0086] In a possible implementation, the angle between the first section 241 and the second section 242 may be, for example, 30°, 45°, or 60°.

This improves the accuracy of the mounting position of the mounting plate 20 relative to the cartridge body 10, and the mounting stability of the mounting plate 20 and the cartridge body 10 is good, thereby ensuring the quality of the recycled ink cartridges.

[0088] In a possible implementation, the positioning structure 21 is disposed on a surface of the second section 242 facing away from the extending portion 25 .

[0089] In one possible implementation, reference Figure 3 and Figure 5 As shown, the outer periphery of the positioning structure 21 has two planes 211 , one of which is located on the side of the positioning structure 21 facing away from the mounting plate 20 , and the other is located on the side of the positioning structure 21 facing the first section 241 .

[0090] In one possible implementation, reference Figure 4 As shown, the box body 10 may be in a cubic shape, and the box body 10 further includes other necessary conventional components, such as a nozzle 16, etc. These conventional components are connected with other components in a conventional manner in the art.
