[0001] This utility model claims the priority of a prior Chinese application with an application date of February 27, 2023, an invention name of “Regenerated Ink Cartridge” and application number of 202320349649.9, and all contents of the prior application are fully cited in this application. Technical Field

[0002] The utility model relates to the field of inkjet imaging, in particular to a regenerated ink cartridge which can be detachably installed in an inkjet imaging device. Background Art

[0003] Figure 1 It is a three-dimensional diagram of an existing ink cartridge, which includes a cover 1 and a shell 2 that are combined with each other. Ink is contained in an ink cavity between the cover 1 and the shell 2. The shell 2 is provided with an ink outlet 23, an air interface 24 and an ink inlet 25. Ink is injected into the ink cavity through the ink inlet 25. The air interface 24 is used to connect with an air pump in an inkjet imaging device. At the same time, the ink cartridge also includes an air bag that is arranged inside the ink cavity and connected to the air interface 24. During the operation of the ink cartridge, the air pump fills gas into the air bag through the air interface 24, causing the air bag to expand, thereby squeezing the ink in the ink cavity toward the ink outlet 23. Finally, the ink is supplied to the imaging device through the ink outlet 23.

[0004] Continue as Figure 1 As shown, an electric contact cavity 27 is formed between the cover 1 and the shell 2, and the original chip 4 is installed in the electric contact cavity 27. The contact pin in the imaging device enters the electric contact cavity 27 through the electrical interface 22 of the electric contact cavity 27, and realizes the electrical connection between the contact pin and the original chip 4; further, an installation identification portion 26 is also provided along the portion adjacent to the electric contact cavity 27, through which the ink cartridges containing different colors of ink can be installed to the correct position.

[0005] In order to reduce the pollution to the environment caused by ink cartridges that have consumed ink (empty ink cartridges / original ink cartridges, i.e. existing ink cartridges), regenerating the original ink cartridges is a common treatment method. During the regeneration process of the existing ink cartridges, it is necessary to install a replacement chip electrically connected to the original chip 4 in the original ink cartridge. However, due to the space limitation of the electrical contact cavity 27, it will be difficult for the replacement chip to achieve a good electrical connection with the original chip 4.

[0006] As described in Chinese patent CN202122993795.9, the replacement chip 5 is configured to be composed of two bendable parts, the part where the electronic device 51 is located is accommodated by the air-avoiding portion 11 arranged on the surface cover, and the part where the connecting contact 52 is located is electrically connected to the original chip 4.

[0007] In order to make the replacement chip 5 bendable, the substrate used to carry the electronic device 51 and the connecting contacts 52 needs to be made of a flexible circuit board. This solution not only increases the cost of the replacement chip 5, but more importantly, it is still difficult to achieve a good electrical connection between the part where the connecting contacts 52 are located and the original chip 4.

[0010] Furthermore, the regenerated ink cartridge has an installation identification portion cut out, and the electrical contact cavity has an entry port facing left or right, and when viewed in the left-right direction, at least the original contact is exposed through the entry port.

[0011] Furthermore, the regenerated ink cartridge further comprises a fitting member, which is installed toward the electrical contact cavity and is used to cover at least a portion of the inlet port.

[0012] Furthermore, when the regenerated toner cartridge is installed, the engaging portion abuts against and engages with the image forming device in the left-right direction.

[0013] Further, the matching piece is installed at the location of the installation identification portion.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Figure 2 It is a three-dimensional diagram of the existing ink cartridge involved in the utility model after being modified; Figure 3 It is a schematic diagram of the state where the replacement chip is installed toward the modified ink cartridge; Figure 4 It is a schematic diagram of the state where the matching parts are installed toward the modified ink cartridge; Figure 5This is a three-dimensional image of the ink cartridge after regeneration.

[0027] For ease of understanding, the same reference numerals are used for the same components as those in the background art hereinafter. Figure 2 In the figure, the length direction of the ink cartridge is defined as the front-to-back direction, the width direction of the ink cartridge is the left-to-right direction, the front-to-back direction and the left-to-right direction intersect, and the direction intersecting with both the front-to-back direction and the left-to-right direction is defined as the up-down direction, preferably, the front-to-back direction, the left-to-right direction and the up-down direction are orthogonal, wherein the face cover 1 and the shell 2 are combined with each other in the left-to-right direction, the ink cavity for storing ink is located between the face cover 1 and the shell 2, the face cover 1 and the shell 2 form the side wall of the ink cartridge, and the ink outlet 23 can be set on any side wall of the ink cartridge.

[0028] The following description will be given by taking the example that the ink outlet 23 is arranged on the front side wall of the ink cartridge, and the ink cartridge is installed forwardly to the imaging device along the front-to-back direction and taken out from the imaging device backwardly. The functions of the ink outlet 23, the air interface 24 and the ink inlet 25 can be referred to the background technology and the Chinese patent cited in the background technology, and will not be described again in the embodiments of the present utility model.

[0029] like Figure 2 As shown, the electrical contact cavity 27 arranged between the cover 1 and the shell 2 has an electrical interface 22 opening toward the front, and the original chip 4 is arranged in the electrical contact cavity 27. The original chip 4 is provided with at least one original contact 41 facing the electrical contact cavity 27, that is, the original contact 41 is located in the electrical contact cavity 27. Optionally, the original chip 4 can be arranged on the cover 1 or on the shell 2.

[0030] When the original ink cartridge is regenerated, at least the installation identification portion 26 is cut off. At this time, the original ink cartridge / existing ink cartridge is modified, and the electrical contact cavity 27 is formed as a cavity open on the left or right. Therefore, the electrical contact cavity 27 has an entrance port 28 facing the left or right, and when viewed in the left and right directions, at least the original contact 41 is exposed through the entrance port 28.

[0031] The replacement chip 5 includes a substrate 50 and connection contacts 52 and external contacts 57 located on opposite sides of the substrate 50, respectively. The connection contacts 52 and external contacts 57 are electrically connected, wherein the connection contacts 52 are used to electrically connect to the original contacts 41, and the external contacts 57 are used to electrically connect to the contact pins in the imaging device.

[0032] like Figure 3 As shown, the replacement chip 5 is electrically connected to the original chip 4 by using the connection tool 9 . At this time, the connection contacts 52 are in contact with the original contacts 41 , and the replacement chip 5 covers at least a portion of the original chip 4 .

[0033] Specifically, the connecting tool 9 can be a welding head, and the replacement chip 5 is combined with the original chip 4 by welding. At this time, the replacement chip 5 can be directly welded on the original chip 4 or welded on the cover 1 / shell 2, as long as the connecting contact 52 can be in contact with the original contact 41; the connecting tool 9 can also be an adhesive, and the replacement chip 5 is combined with the original chip 4 by bonding. Similarly, the replacement chip 5 can be bonded on the original chip 4 or bonded on the cover 1 / shell 2.

[0034] like Figure 4 As shown, after the replacement chip 5 is combined with the original chip 4, the matching piece 29 is installed toward the electrical contact cavity 27 to cover at least a portion of the access opening 28. The matching piece 29 can be installed by welding, bonding, clamping, etc. Figure 5 As shown, when the mating piece 29 is installed, the space of the electrical contact cavity 27 is reduced again, and the replacement chip 5 faces the electrical contact cavity 27. Specifically, the external contact point 57 faces the electrical contact cavity 27, and the external contact point 57 is located in the electrical contact cavity 27. The contact pin in the imaging device can still enter the electrical contact cavity 27 through the electrical interface 22 and realize the electrical connection between the contact pin and the external contact point 57.

[0035] Furthermore, the fitting 29 is provided with a fitting portion 291 for fitting with the imaging device. When the regenerated ink cartridge is installed, the regenerated ink cartridge can be stably positioned in the imaging device through the abutment and fit between the fitting portion 291 and the imaging device in the left-right direction. Preferably, the fitting portion 291 is provided as a cavity structure, so that the ink cartridge installed with the fitting 29 can be universally used.

[0036] [Regeneration method]

[0037] According to the above description, the ink cartridge regeneration method of the utility model is as follows:

[0038] Steps to prepare the original ink cartridge;

[0039] Steps to modify the original ink cartridge;

[0040] A step of electrically connecting the replacement chip 5 to the original chip 4 using a connection tool 9;

[0041] Steps for installing the fitting 29.

[0042] Among them, the regeneration method also includes a step of cleaning the ink cartridge, and the cleaning step can be performed before or after the original ink cartridge is modified, or after the replacement chip 5 is electrically connected to the original chip 4; the matching part 29 is installed at the position of the installation identification part 26, and in the step of modifying the original ink cartridge, the space of the electrical contact cavity 27 becomes larger, so that the operator can easily achieve the electrical connection between the replacement chip 5 and the original chip 4.

[0043] In some embodiments, when the ink cartridge can cooperate with the imaging device through other positions to achieve the effect / function achieved by the cooperation between the mating portion 291 and the imaging device, the installation step of the mating part 29 in the above steps can also be omitted. At this time, the regenerated ink cartridge no longer has the mating part 29.

[0044] [Beneficial Effects]

[0045] The regeneration method has the beneficial effects of:

[0046] On the one hand, the replacement chip 5 does not need to be configured to be bendable, so that the substrate 50 of the replacement chip 5 does not need to use a more expensive flexible circuit board, but can use an ordinary substrate, and finally the replacement chip 5 can be made into an ordinary chip.

[0047] On the one hand, the storage unit for storing data in the replacement chip 5 can be installed in the electrical contact cavity 27 at the same time. Not only does the storage unit not need to be exposed to the outside of the electrical contact cavity 27 and be protected, the cover 1 or the shell 2 does not need to be provided with a hole or groove for accommodating the storage unit. It can be realized that the storage unit can be set on the same side as the connection contact 52 or the external contact 57.

[0048] On the one hand, the above-mentioned original contact 41 and external contact 57 face the electrical contact cavity 27, which means that the original contact 41 and the external contact 57 are located in the electrical contact cavity 27. After the installation identification portion 26 is cut off, the space of the electrical contact cavity 27 becomes larger, and accordingly, the operating space of the operator also becomes larger, which is more conducive to achieving a stable electrical connection between the replacement chip 5 and the original chip 4.

[0049] On the one hand, after the installation identification portion 26 is cut off, the electrical contact cavity 27 forms an entry port 28 whose opening direction is different from that of the electrical interface 22. Specifically, the opening direction of the entry port 28 intersects with the opening direction of the electrical interface 22, and the original contact 41 is exposed through the entry port 28. In this way, through the entry port 28 and the enlarged electrical interface 22, the operator can use the connection tool 9 to conveniently operate the replacement chip 5, thereby achieving a stable electrical connection between the replacement chip 5 and the original chip 4.

[0050] On the one hand, after the replacement chip 5 is electrically connected to the original chip 4, the fitting 29 is installed at the entrance port 28, and the space of the electrical contact cavity 27 is reduced again, which is not only conducive to preventing the replacement chip 5 from falling off from the entrance port 28, but also can limit the contact pin to prevent the contact pin from failing to form a good electrical contact with the replacement chip 5 due to the displacement of the installation position of the ink cartridge.

[0051] [Other Notes]

[0052] As described above, the entry port 28 is formed by cutting off the installation identification portion 26. Through the entry port 28, the operator can easily achieve a stable electrical connection between the replacement chip 5 and the original chip 4. In the up and down directions, the electrical contact cavity 27 does not form an opening. As shown in the figure, a limiting plate 2a is formed above the electrical contact cavity 27. The side wall of the limiting plate 2a facing downward forms a side wall of the electrical contact cavity 27. During the installation process of the mating component 29, the limiting plate 2a can play a role in guiding the mating component 29. When the mating component 29 is installed, the limiting plate 2a can also position the mating component 29.

[0053] In some embodiments, at least a portion of the limiting plate 2a may be cut off to further increase the operating space of the electrical contact cavity 27. When the limiting plate 2a is completely cut off, the fitting 29 may also be formed to guide and position other side walls of the electrical contact cavity 27.

[0054] Furthermore, in some embodiments, the fitting 29 may also be provided with a covering portion (i.e., at least a portion of the limiting plate 2a) that can cover the electrical contact cavity from above. When the limiting plate 2a is completely removed, as the fitting 29 is installed, the covering portion again covers the top of the electrical contact cavity 27. In this way, the electrical contact cavity 27 finally only has an electrical interface 22 facing forward, and the original chip 4 and the replacement chip 5 located in the electrical contact cavity 27 can be effectively protected, and external dust or impurities are not easy to enter the electrical contact cavity 27.

[0055] As described above, by adopting the above-mentioned regeneration method, the cost of replacing the chip 5 can be reduced. At the same time, the replacement chip 5 and the original chip 4 can also achieve a stable electrical connection. Furthermore, the overall appearance of the regenerated ink cartridge is basically unchanged, and the user will not be confused when using the regenerated ink cartridge.
