[0079] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0080] Figure 1 is a schematic diagram of the structure of an original ink cartridge A in the related art, Figure 1 The original ink cartridge A in the figure comprises a bottom shell 10 and a cover 20 covering the bottom shell 10, and the cover 20 is fixed to the bottom shell 10 by welding or pasting. The bottom shell 10 has a side surface 11 opposite to the cover 20, a top surface 12 and a bottom surface 13 adjacent to the side surface 11, and the top surface 12 and the bottom surface 13 are opposite to each other; the front surface 14 is located between the top surface 12 and the bottom surface 13, and the rear surface 15 is opposite to the front surface 14. The top surface 12 of the original ink cartridge A has a positioning groove, which cooperates with the protrusion (not shown) of the printer to play a certain positioning role in the installation process of the original ink cartridge A.

[0081] The front surface 14 of the bottom shell 10 is provided with an ink outlet, a vent, an identification card position 19, and a chip from bottom to top. When the original ink cartridge A is installed in the printer installation part (not shown), the ink outlet is connected to the ink supply needle (not shown) of the installation part to realize ink supply; the vent is connected to the pump of the printer installation part to realize pressurization of the deformable chamber inside the original ink cartridge A. An identification card position 19 and a chip are provided at the intersection of the top surface 12 and the front surface 14. The identification card position 19 is closer to the side surface 11 in a direction perpendicular to the side surface 11 relative to the chip. A partition wall 17 is provided between the identification card position 19 and the chip, and the identification card position 19 and the chip are respectively provided on both sides of the partition wall 17. Usually, a set of original ink cartridges will be provided with three color original ink cartridges and one black original ink cartridge, namely BK, C, M, and Y. The shape of the identification card position of original ink cartridges of different colors is set differently, and the shape of the identification card position of original ink cartridges in different regions may also be set differently. In this embodiment, the identification card position is set in a cross shape, and other similar reasonable shape structures are all acceptable. The electrical interface of the chip faces a direction perpendicular to the side surface. When the original ink cartridge A is installed in the printer, the electrical interface contacts the contact pins (not shown) of the printer to achieve connection.

[0082] Figure 2 Schematic diagram of the structure of the original ink cartridge B in the related art. Figure 2 As shown, the original ink cartridge B includes a shell 10 and a cover 20, and the shell 10 and the cover 20 are basically similar to those of the original ink cartridge A and will not be described in detail here. The difference between the original ink cartridge B and the original ink cartridge A is that the chip in the original ink cartridge B is bonded to the inner side of the cover 20, and the electrical interface of the chip faces the partition wall 17 and contacts the contact pin of the printer.

[0083] When Figure 1 After the ink in the original ink cartridge A shown is consumed, the original ink cartridge A can be recycled. Since the information of the chip of the original ink cartridge A has been exhausted or damaged, the chip of the original ink cartridge A needs to be disassembled, and the chip is generally disassembled by mechanical means such as prying. After the original chip of the original ink cartridge A is disassembled, the chip installation position on the side of the partition wall may be damaged. At this time, if a new chip is directly installed in the position of the original chip, the positioning may be inaccurate, resulting in the original ink cartridge being unable to be recognized after being installed in the printer.

[0084] In addition, when the original ink cartridge A is no longer produced and becomes idle, the original ink cartridge B is insufficient in stock and the existing original ink cartridge A needs to be regenerated to obtain the original ink cartridge B. Since the installation positions of the chips of the original ink cartridge A and the original ink cartridge B are different, the chip position needs to be changed, and after the ink of the new ink cartridge is used up, the chip needs to be replaced again. When removing the chip, damage to the chip installation position and the ink cartridge should be avoided.

[0085] To solve the above problems, an embodiment of the present invention provides a recycling ink cartridge and an ink cartridge recycling method, wherein the recycling ink cartridge includes a chip fixing mechanism, the chip fixing mechanism is installed on the ink cartridge, and the installation position of the chip on the ink cartridge is changed to realize the replacement and recycling of the ink cartridge type; furthermore, the chip and the chip fixing mechanism are detachably connected, and the chip fixing mechanism is detachably installed on the ink cartridge, so that damage to the chip installation position and the ink cartridge can be avoided when the chip is removed.

It can be understood that the through hole provided on the cover 20 to communicate with the chip 50 is not only circular, but also can be other shapes such as rectangular, triangular, etc., and no specific limitation is made here.

[0121] Further, such as Fig. 20 As shown, the chip 50 is fixed to the front end of the cover 20 by gluing, and welding wires are arranged around the cover 20, and the welding wires surround the cover in a trapezoidal shape, matching the opening shape of the bottom shell. A plurality of positioning columns are also arranged around the cover to limit the position of the cover when assembling the cover and the bottom shell, so as to make the welding fixation more accurate.

[0122] like Fig.21 As shown, the chip 50 is selectively movably mounted on the cover 20; for example, a chip mounting area is provided on the back side of the cover 20, and a third slider is provided on both sides of the chip mounting area, and a third slide groove is provided on the third slider 27. The third slide groove is tightly fitted with the chip 50, and both sides of the chip 50 are inserted into the third slide groove and confined in the third slide groove, thereby realizing the movability of the chip 50 on the cover 20.

[0123] Further, such as Fig. 22As shown, a first chip holder 28 is further provided between the chip 50 and the cover 20, and the chip 50 can be mounted on the first chip holder 28 in the form of a slide groove; for example, two third sliders 27 can be relatively provided on the first chip holder 28, and the third slider 27 is provided with a third slide groove, and the two sides of the chip are inserted into the two relatively provided third slide grooves; thereby realizing that the chip 50 is movably mounted on the first chip holder 28.

[0124] On the basis of the original ink cartridge A, a new ink cartridge A is formed by replacing a new chip, and the chip and identification card position of the original ink cartridge A need to be removed; to simplify the process, the removal of the identification card position and the milling of the surface of the partition wall can be carried out at the same time; or the partition wall is severely damaged during the chip removal process and cannot be repaired or the repair cost is high; the identification card position and the partition wall can be removed at the same time, and the new chip can be installed on the ink cartridge using a new chip mounting frame.

[0125] like Fig.23 As shown, this embodiment provides another chip fixing mechanism, which includes a second chip mounting frame 60, and the second chip mounting frame 60 includes a first mounting plate 61 and a second mounting plate 62 that are arranged opposite to each other, and the first mounting plate 61 and the second mounting plate 62 are connected together; the first mounting plate 61 is arranged close to the cover 20 or the first mounting plate 61 can be arranged flush with the cover 20; the second mounting plate 62 is located in the middle part of the notch 40, which can replace the original partition wall 17; wherein, the chip 50 is mounted on the side of the first mounting plate 61 facing the second mounting plate 62, and the electrical interface of the chip 50 faces the second mounting plate 62. A first mounting portion 63 is arranged on the side of the second mounting plate 62 that is away from the first mounting plate 61, and is used to detachably mount the second chip mounting frame 60 on the bottom shell 10 through the first mounting portion 63.

[0126] The bottom shell 10 of the original ink cartridge A is provided with a groove track 18, which is located on the side of the side surface 11 of the original ink cartridge A close to the front surface 14, and the notch 40 is formed at the upper end of the side surface 11, and one end of the groove track 18 is located below the notch 40 and is flush with the secondary top surface 41. In this embodiment, in order to reasonably utilize the existing groove track 18 and facilitate the installation of the new chip on the ink cartridge, the chip 50 can be installed on the first mounting plate 61, and then plugged into the groove track 18 through the first mounting portion 63 on the second mounting plate 62.

[0127] In addition, if Fig.24As shown, on the basis of the original ink cartridge A, after the partition wall and the chip holder of the original ink cartridge A are cut off, this embodiment provides another way to install the chip to the ink cartridge and form a new ink cartridge B. Specifically, the chip fixing mechanism includes a third chip mounting frame 70, and the third chip mounting frame 70 includes a third mounting plate 71, and the third mounting plate 71 can be arranged flush with the face cover 20. A second mounting portion 72 is arranged at one end of the third mounting plate 71 away from the notch 40, and the second mounting portion 72 is actually a positioning protrusion of the third mounting plate 71 perpendicular to its surface. The face cover 20 is provided with a plug-in interface 22 that cooperates with the second mounting portion 72 at a position close to the notch 40, and the plug-in interface 22 is tightly matched with the positioning protrusion. When a new chip needs to be installed in the ink cartridge, the chip 50 can be pre-installed on the third mounting plate 71, and the second mounting portion 72 is plugged into the plug-in interface 22 of the face cover 20, thereby realizing the installation of the chip 50 on the ink cartridge through the third chip mounting frame 70.

It can be understood that the sliding mounting method of the chip 50 and the second chip fixing seat 73 and the clamping form of the second chip fixing seat 73 and the third mounting plate 71 can be referred to. Fig. 22 As shown, no further description is given here.

[0129] like Fig. 27 As shown, this embodiment also provides an ink cartridge recycling method, which can be applied to the original ink cartridge A and change its type to form a new ink cartridge B, which includes the following steps:

[0130] Step a) cleaning the original ink cartridge; specifically, removing the remaining ink from the idle original ink cartridge A, and flushing the original ink cartridge A, so that the new ink cartridge B made from the original ink cartridge A can be filled with inks of different colors.

[0131] Step b) removing the identification card position of the original ink cartridge; specifically, the original ink cartridge A includes a partition wall, the original chip is located on the side of the partition wall facing the cover, and the identification card position and the original chip are respectively located on both sides of the partition wall, and the identification card position is removed from the original ink cartridge A using a special cutting tool.

[0132] Step c) disassembling the chip of the original ink cartridge; specifically, using a tool to lift and peel off the chip from the partition wall, and then milling and trimming the surface of the partition wall after peeling.

[0133] Step d) The chip is mounted on the ink cartridge by the chip fixing mechanism to form a new ink cartridge, the chip is arranged close to the cover, and the electrical interface of the chip faces the side opposite to the cover. Specifically, a suitable chip fixing mechanism is selected according to the shape of the notch of the ink cartridge; for example, the chip fixing mechanism can be a first positioning surface arranged on the cover, or a first chip mounting frame, the chip can be detachably or bonded to the chip fixing mechanism, and the chip fixing mechanism can be installed in the notch, so that the new chip is mounted on the shell of the ink cartridge to form a new ink cartridge B, and the electrical interface of the chip in the new ink cartridge B is opposite to the partition wall or the side surface of the bottom shell.

[0134] Step e) filling the formed new ink cartridge with ink.

[0135] Furthermore, to simplify the process, the above steps b and c can be simplified into one step, that is, the partition wall and the identification position can be removed, and there is no partition wall in the gap. The second chip mounting frame 60 can be used to mount the chip on the ink cartridge to form a new ink cartridge B.

[0136] The original ink cartridge A involved in this embodiment includes an ink storage cavity and a spare cavity. The ink storage cavity only occupies about two-thirds of the capacity of this ink cartridge A. The original ink cartridge A still has spare space, and the spare cavity and the ink storage cavity are separated by a partition. This type of ink cartridge is generally a trial ink cartridge that comes with the printer and has a small amount of ink. In order to ensure that this type of ink cartridge can be used like other normal ink cartridges after recycling, that is, it has a normal amount of ink, it is necessary to remove the cover, process and cut the partition, so that the spare cavity is connected to the ink storage cavity, improve the utilization rate of the ink cartridge, and expand the ink cartridge.

[0137] like Fig.28 As shown, for the above-mentioned ink cartridge A including an ink storage chamber and a spare chamber to be recycled, the present embodiment further provides an ink cartridge recycling method, which is applicable to the ink cartridge A including an ink storage chamber and a spare chamber, and changes its type to form a new ink cartridge B; specifically comprising the following steps: first, extract the remaining ink in the original ink cartridge A and clean the original ink cartridge A; secondly, cut off the identification card position of the original ink cartridge A, disassemble the original chip and mill the partition wall; then cut off the surface cover and replace it with a new surface cover, the new surface cover covers the gap, and installs a new chip on the new surface cover, with the electrical interface of the chip facing the partition wall plate, and finally the newly formed ink cartridge B is filled with ink.

[0138] The present embodiment also provides a method for forming a new ink cartridge B from an original ink cartridge B. The new ink cartridge B is formed based on the original ink cartridge. Since it does not involve changes in the position of the chip, there is no need to additionally design a chip fixing mechanism to position the chip. It is only necessary to process the surface cover of the original ink cartridge B, mill off the original chip position, and process a clamping position, and then install the new chip.

[0139] It is understandable that the above method generates ink cartridge B based on ink cartridge A, and can also generate a new ink cartridge A based on the original ink cartridge B, as follows: Fig.29 As shown, the method for forming a new ink cartridge A based on the original ink cartridge B includes the following steps: cleaning the original ink cartridge B, cutting off the identification card position of the original ink cartridge B, milling the chip mounting position of the partition wall, and directly bonding the new chip to the partition wall; or clearing the original chip mounting position of the face cover and forming a gap, and then using the second chip mounting frame provided in the above embodiment to mount the chip on the original ink cartridge B to form a new ink cartridge A. The above-mentioned second chip mounting frame includes a first mounting plate and a second mounting plate that are relatively arranged. The chip is usually detachable or bonded to the second mounting plate so that the electrical interface of the chip faces the face cover. In addition, in order to enable the regenerated ink cartridge to adapt to the printer of type A ink cartridge, it is necessary to open a positioning groove at the corresponding position of the top surface of the original ink cartridge B.

[0140] In addition, in view of the above-mentioned original ink cartridge A including the ink storage cavity and the empty cavity can be replaced with a new cover to form a new ink cartridge B, the original ink cartridge B with a similar cavity can also be replaced with a cover to form a new ink cartridge A. Fig.30 The recycling method is to clean the ink cartridge, cut off the identification card position, cut off the cover, expand the ink cartridge, and fix and install the new cover and new chip. Since the chip position of the type A ink cartridge is different from that of the type B ink cartridge, it can be directly pasted on the partition wall, that is, there is no need to fix the chip on the cover, and each can be installed independently. It should be noted that in order for the recycled ink cartridge to adapt to the printer of the type A ink cartridge, it is necessary to open a positioning groove at the corresponding position of the top surface and mill off the support part at the upper end of the front surface.
