Description

Technical Field

[0001] The invention relates to the field of printing consumables, in particular to an ink cartridge and a method for manufacturing a regenerated ink cartridge. Background Art

[0002] The printing method of an inkjet printer is usually that the ink source is provided by an ink container, and the ink is ejected from the print head nozzle onto a recording medium such as paper under the drive of a print signal to form a record of characters or graphics. Common commercially available inkjet printers include piezoelectric inkjet printers and thermal bubble inkjet printers.

[0003] In order to increase the consumption of ink cartridges by users, manufacturers of thermal bubble inkjet printers usually make the ink chamber of the ink cartridges smaller, and even use sponge and other ink-absorbing materials as ink storage carriers to further reduce the size. This type of ink cartridge structure mostly uses an integrated ink cartridge that integrates an inkjet head with a circuit board and an ink container. The cost of the ink cartridge mainly lies in the inkjet head and the circuit board (i.e., chip), and these components have a long life and can be used many times. An ink cartridge can usually be used dozens or even hundreds of times, that is, it can be used even after adding ink dozens or even hundreds of times. On the other hand, since the ink storage cavity of this type of ink cartridge is relatively small and sponge and other ink absorbing materials are used as ink absorbing carriers, it is very inconvenient for users to add ink, and users can only add a small amount of ink each time after use. Most ink cartridges can only add 1 gram to 2 grams of ink, and there is no ink at the printing nozzle before adding ink. Therefore, after adding ink, since the ink is in the sponge and other ink absorbing materials, it is necessary to use tools to drain the ink in the sponge to the printing nozzle, otherwise printing will still not be possible. Therefore, draining the ink under limited ink filling conditions actually restricts users from adding ink.

[0004] Therefore, the existing ink cartridges not only have a small ink capacity, but also restrict users from adding ink. Directly discarding the ink in the ink cartridge after use will cause waste of resources and environmental pollution. Summary of the invention

[0005] The first object of the present invention is to provide an ink cartridge with large capacity and convenient ink filling for recycling.

[0006] The second object of the present invention is to provide a method for manufacturing the above-mentioned regenerated ink cartridge.

[0007] To achieve the above first purpose, the present invention provides an ink cartridge, comprising a box body, a cover and an ink storage shell, wherein an ink cartridge cavity is arranged in the box body, an inkjet head is arranged at the bottom of the box body, and a chip is arranged on the side wall of the box body. The cover is arranged at the top of the box body, and an ink adding hole and an air guide hole are opened on the cover, and the ink adding hole and the air guide hole are both sealed, the ink storage shell is arranged in the ink cartridge cavity, a first ink storage cavity is arranged in the ink storage shell, an ink absorbing component is arranged in the first ink storage cavity, and the inkjet head is connected with the first ink storage cavity. A second ink storage cavity is arranged outside the ink storage shell, and the second ink storage cavity is located in the ink cartridge cavity; a connecting hole is opened at the bottom end of the ink storage shell, and the first ink storage cavity is connected with the second ink storage cavity through the connecting hole; the ink storage shell is sealed and connected with the cover, the air guide hole is connected with the first ink storage cavity, and the ink adding hole is connected with the second ink storage cavity.

[0008] It can be seen from the above scheme that by remanufacturing the original ink cartridge, the ink storage shell and the surface cover are sealed and connected, the air guide hole is connected to the first ink storage chamber, and the ink filling hole is connected to the second ink storage chamber. The user can fill ink into the second ink storage chamber through the ink filling hole, or fill ink into the first ink storage chamber through the air guide hole, thereby greatly expanding the capacity of the ink cartridge and realizing the recycling of the ink cartridge, thereby saving resources and protecting the environment.

[0009] In addition, by sealing the ink storage housing and the cover, the second ink storage chamber is formed into a closed space with only one connecting hole connected to the outside. When the printer is not working, the gravity of the ink in the second ink storage chamber is equal to the negative pressure generated above the second ink storage chamber, and the ink will not flow to the first ink storage chamber, thereby achieving a static balance of pressure, thereby preventing the ink in the second ink storage chamber from constantly flowing to the first ink storage chamber and then to the inkjet head, causing ink leakage. When the printer is working, the ink in the second ink storage chamber drops, and the air above the second ink storage chamber becomes thinner, generating negative pressure, so that the ink in the second ink storage chamber will not flow into the first ink storage chamber without restraint, and is always in dynamic balance. As the printing process continues, the ink in the second ink storage chamber continues to drop. When the negative pressure of the air above the second ink storage chamber reaches a certain level, the air will enter the second ink storage chamber from the connecting hole, and then rise to the upper side of the second ink storage chamber, relieving the negative pressure of the air and re-establishing a new pressure balance to ensure the normal supply of ink.

[0010] A preferred solution is that the ink storage housing and the surface cover are integrally formed; or the ink storage housing and the surface cover are fixedly connected by bonding or welding.

[0011] This shows that a good seal between the ink storage housing and the face cover is ensured.

[0012] A preferred solution is that the upper surface of the face cover is provided with a mounting buckle position and a handle buckle position, the mounting buckle position and the handle buckle position are respectively arranged at both ends of the length direction of the face cover, and both protrude upward from the upper surface of the face cover.

[0013] It can be seen that it is convenient for the user to use his fingers to snap the installation buckle and the handle buckle, so as to smoothly install the ink cartridge into the printer.

[0014] A further solution is that the chip is located on the side wall at one end of the box body in the length direction, and the inkjet head is located on the side of the bottom wall of the box body close to the chip; in the length direction of the face cover, the mounting buckle is located at the end of the face cover close to the chip; a groove is provided on the bottom wall of the box body close to the chip, and a positioning column is provided on the ink storage shell, and the positioning column extends into the groove from top to bottom.

[0015] It can be seen that the positioning column and the groove cooperate to achieve the anti-mistake function, preventing the cover from being installed upside down in the length direction, so that the installation buckles on the cover cannot cooperate with the printer, thereby affecting the operation of the printer.

[0016] A further solution is that the face cover is provided with an expansion portion, which is located between the mounting buckle position and the handle buckle position, the expansion portion protrudes upward from the upper surface of the face cover, and the expansion portion is recessed upward from the lower surface of the face cover; at least one of the first ink storage cavity and the second ink storage cavity is arranged opposite to the expansion portion in the vertical direction.

[0017] It can be seen that providing an expansion portion on the cover can further increase the capacity of the ink cartridge.

[0018] A preferred solution is that sealing plugs are provided in both the ink adding hole and the air guiding hole; or the ink adding hole and the air guiding hole are sealed by a sealing film.

[0019] It can be seen that the provision of the sealing plug facilitates sealing or opening the ink adding hole and the air guide hole.

[0020] A preferred solution is that the bottom end of the ink storage shell is adjacent to the bottom wall of the box body; or the bottom end of the ink storage shell is fixedly connected to the bottom wall of the box body; or there is a gap between the bottom end of the ink storage shell and the bottom wall of the box body.

[0021] It can be seen that there is no strict restriction on the connection between the bottom end of the ink storage shell and the bottom wall of the box body, and the manufacturing process is simpler.

[0022] To achieve the above second purpose, the present invention provides a method for manufacturing a regenerated ink cartridge, wherein an original ink cartridge is remanufactured to form a regenerated ink cartridge, wherein the original ink cartridge comprises: an original box body; an original ink cartridge cavity is arranged in the original box body, an original ink storage shell is arranged in the original ink cartridge cavity, the original ink storage shell is connected to the bottom wall of the original box body, the original ink storage shell is arranged with an original ink storage cavity, an original ink absorbing component is arranged in the original ink storage cavity, an original inkjet head is arranged at the bottom of the original box body, and the original inkjet head and the original ink storage are connected to each other. The original ink cartridge is connected to the original ink cavity, the side wall of the original box body is provided with an original chip, the original box body and the original ink storage shell form a cavity; the original cover is provided at the top of the original box body, an air passage is provided between the original cover and the top wall of the original ink storage shell, the original cover is provided with an original ink adding hole and an original air guide hole, the original ink adding hole is connected to the original ink storage cavity, and the original air guide hole is connected to the cavity; the regenerated ink cartridge comprises: a box body, an ink cartridge cavity is provided in the box body, an inkjet head is provided at the bottom of the box body, and the side wall of the box body A chip is provided; a surface cover is provided at the top of the box body, and an ink adding hole and an air guide hole are provided on the surface cover; an ink storage shell is provided in the ink cartridge cavity, a first ink storage cavity is provided in the ink storage shell, an ink absorbing component is provided in the first ink storage cavity, and the inkjet head is connected with the first ink storage cavity; a second ink storage cavity is provided outside the ink storage shell, and the second ink storage cavity is located in the ink cartridge cavity; a connecting hole is provided at the bottom end of the ink storage shell, and the first ink storage cavity is connected with the second ink storage cavity through the connecting hole; the ink storage shell is sealed with the surface cover The air guide hole is connected with the first ink storage cavity, and the ink filling hole is connected with the second ink storage cavity. The manufacturing method comprises: a disassembly step: disassembling the original ink cartridge; a cleaning step: cleaning the original ink cartridge; a modification step: modifying the original box body into a box body, modifying the original surface cover into a surface cover, modifying the original ink storage shell into an ink storage shell, and assembling the regenerated ink cartridge; an ink filling step: filling the second ink storage cavity with ink through the ink filling hole, filling the first ink storage cavity with ink through the air guide hole, and sealing the ink filling hole and the air guide hole after adding ink.

[0023] As can be seen from the above scheme, by remanufacturing the original ink cartridge, the ink storage housing is sealed and connected to the cover, the air guide hole is connected to the first ink storage chamber, and the ink filling hole is connected to the second ink storage chamber. The user can fill the ink into the second ink storage chamber through the ink filling hole, and can also fill the ink into the first ink storage chamber through the air guide hole, thereby greatly expanding the capacity of the ink cartridge, realizing the recycling of the ink cartridge, thereby saving resources and protecting the environment. In addition, by sealing the ink storage housing and the cover, the second ink storage chamber is formed into a closed space with only one connecting hole connected to the outside, so that the air above the second ink storage chamber forms a pressure balance with the ink in the second ink storage chamber, thereby preventing the ink in the second ink storage chamber from constantly flowing to the first ink storage chamber and then to the inkjet head, causing ink leakage.

[0024] A preferred solution is that the modification steps include: cutting and removing the original ink storage shell from the original box body to form a box body; replacing the original face cover with a face cover, sealingly connecting the ink storage shell to the lower surface of the face cover, and installing the face cover on the box body; or replacing the original face cover with a face cover, and installing the integrally formed ink storage shell and face cover on the box body.

[0025] It can be seen from this that the original ink storage shell in the original box body can be removed, and the new ink storage shell that is integrally formed with the face cover or fixedly connected to the face cover can replace the original face cover, thereby ensuring the sealing of the connection position between the ink storage shell and the face cover.

[0026] A preferred solution is that the modification steps include: opening a connecting hole on the original ink storage shell, installing a seal at the air channel, using the original ink filling hole as the air guide hole of the regenerated ink cartridge, and using the original air guide hole as the ink filling hole of the regenerated ink cartridge.

[0027] It can be seen from this that a seal can be directly set at the air channel position between the original ink storage shell and the original surface cover to seal the air channel, and a connecting hole can be opened at the bottom of the original ink storage shell. This manufacturing method is simpler and has lower cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Both original ink cartridges and remanufactured ink cartridges are printhead cartridges installed in inkjet printers.

[0038] like Figures 1 to 3 As shown, the original ink cartridge 10 includes an original box body 11 and an original cover 12, the original cover 12 is provided with an original ink filling hole 121 and an original air guide hole 122 penetrating the original cover 12, an original ink cartridge cavity 110 is provided in the original box body 11, an original ink storage shell 13 is provided in the original ink cartridge cavity 110, the original ink storage shell 13 is connected to the bottom wall of the original box body 11, the original ink storage shell 13 is provided with an original ink storage cavity 131, the original ink storage cavity 131 is provided with an original ink absorbing component 14 made of sponge and other materials, and the bottom of the original box body 11 is provided with an original ink spraying part 14 that can directly spray ink onto a medium such as paper An inkjet head 17 is installed, an ink outlet 132 is provided at the bottom of the original ink storage cavity 131, the original inkjet head 17 is connected with the original ink storage cavity 131 through the ink outlet 132, the side wall of the original box body 11 is provided with an original chip 16, the original chip 16 is electrically connected with the original inkjet head 17, the original box body 11 and the original ink storage shell 13 form a cavity 111, the cavity 111 surrounds the original ink storage cavity 131, the original ink adding hole 121 is connected with the original ink storage cavity 131, the original air guide hole 122 is connected with the cavity 111, there is no ink in the cavity 111, and it only serves to connect the original ink storage cavity 131 with the original air guide hole 122.

[0039] like Figure 3 As shown, the original face cover 12 is arranged at the top of the original box body 11, and an air channel 15 is arranged between the original face cover 12 and the top wall of the original ink storage shell 13, which is used to connect the original ink storage cavity 131 with the atmosphere. When the printer is working, air enters from the original air guide hole 122 and enters the original ink storage cavity 131 through the air channel 15, thereby ensuring the pressure balance in the original ink storage cavity 131.

[0040] After the ink in the original ink storage cavity 131 of the original ink cartridge 10 is used up, the original ink filling hole 121 can be used to fill the original ink storage cavity 131 with ink. Due to the setting of the original ink absorbing component 14, it is difficult to add ink and the amount of ink added is small. If the amount of ink added is large, the ink will flow from the air channel 15 into the cavity 111 outside the original ink storage cavity 131, or flow out from the original air guide hole 122 after entering the cavity 111. At the same time, since the air channel 15 is located at the top of the original ink storage cavity 131, the ink that has flowed into the cavity 111 cannot flow back into the original ink storage cavity 131 for use.

[0041] In order to realize the recycling of ink cartridges, save resources and protect the environment, the present invention forms a new regenerated ink cartridge by remanufacturing the existing original ink cartridge 10 after the ink is used up. The present invention is described in detail below in conjunction with various embodiments.

[0042] First embodiment of the method for manufacturing ink cartridge and regenerated ink cartridge:

[0043] The ink cartridge may be a newly produced ink cartridge, or a remanufactured ink cartridge formed by remanufacturing the original ink cartridge 10 .

[0044] See also Figures 4 to 6 The ink cartridge 20 of this embodiment includes a box body 3, a cover 4 and an ink storage shell 5. An ink cartridge cavity 30 is provided in the box body 3. The top of the box body 3 is open. Preferably, the cover 4 is fixed to the open end 31 of the box body 3 by gluing or welding and the open end 31 is sealed.

[0045] An inkjet head 32 is disposed at the bottom of the box body 3 , a chip 33 is disposed on a side wall 301 at one end of the box body 3 in the length direction (the direction indicated by arrow L), and the inkjet head 32 is located on a side of the bottom wall 302 of the box body 3 close to the chip 33 .

[0046] The ink storage shell 5 is in the shape of a rectangular ring which is open at the top and bottom. The face cover 4 is connected to the upper open end of the ink storage shell 5. The ink storage shell 5 is arranged in the ink cartridge cavity 30. The bottom end of the ink storage shell 5 is adjacent to the bottom wall 302 of the box body 3. A first ink storage cavity 51 is arranged in the ink storage shell 5. An ink absorbing component 6 is arranged in the first ink storage cavity 51. Preferably, the ink absorbing component 6 is a sponge for absorbing ink. On the one hand, it prevents the ink in the ink cartridge cavity 30 from leaking during the transportation of the ink cartridge and contaminating the surrounding products. On the other hand, during the printing operation, it ensures that the ink in the ink cartridge cavity 30 is subjected to negative pressure before flowing to the inkjet head 32, so as to prevent the ink in the ink cartridge cavity 30 from continuously flowing to the inkjet head 32 and causing ink leakage.

[0047] The bottom of the first ink storage chamber 51 is provided with an ink outlet (not shown), and the inkjet head 32 is connected to the first ink storage chamber 51 through the ink outlet. A second ink storage chamber 34 is provided outside the ink storage housing 5. The second ink storage chamber 34 is located inside the ink cartridge cavity 30 and surrounds the first ink storage chamber 51. The volume of the second ink storage chamber 34 is greater than that of the first ink storage chamber 51. A connecting hole 52 is provided at the bottom end of the ink storage housing 5. The first ink storage chamber 51 is connected to the second ink storage chamber 34 through the connecting hole 52.

[0048] The face cover 4 is provided with an ink adding hole 41 and an air guide hole 42 which penetrate the face cover 4. The air guide hole 42 is connected to the first ink storage chamber 51, and the ink adding hole 41 is connected to the second ink storage chamber 34. Sealing plugs (not shown) made of elastic materials such as rubber are detachably installed in the ink adding hole 41 and the air guide hole 42. The sealing plugs are used to seal or open the ink adding hole 41 and the air guide hole 42. The ink adding hole 41 is used to fill ink into the second ink storage chamber 34. The air guide hole 42 has the functions of adding ink and guiding air at the same time. When adding ink, ink can be filled into the first ink storage chamber 51 through the air guide hole 42. When printing, air can enter the first ink storage chamber 51 through the air guide hole 42, thereby balancing the pressure in the ink cartridge cavity 30. The ink storage housing 5 and the face cover 4 are integrally formed and sealedly connected, that is, there is no gap between the ink storage housing 5 and the face cover 4, thereby ensuring the airtightness of the second ink storage chamber 34, so that the second ink storage chamber 34 is only connected to the outside through the connecting hole 52 when the printer is working. Optionally, the ink storage housing 5 and the surface cover 4 may also be sealed and connected by bonding or welding.

[0049] In addition, the upper surface of the face cover 4 is provided with a mounting buckle position 43 and a handle buckle position 44, which are respectively arranged at both ends of the length direction L of the face cover 4 and both protrude upward from the upper surface of the face cover 4. In the length direction L of the face cover 4, the mounting buckle position 43 is located at one end of the face cover 4 close to the chip 33. A groove 35 is provided on the side of the bottom wall 302 of the box body 3 close to the chip 33, and a positioning column 53 is provided on the ink storage housing 5, and the positioning column 53 extends into the groove 35 from top to bottom. The positioning column 53 cooperates with the groove 35 to realize the function of foolproofing, so as to prevent the face cover 4 from being reversely installed in the length direction L, so that the mounting buckle position 43 on the face cover 4 cannot cooperate with the printer, thereby affecting the operation of the printer.

[0050] The manufacturing method of the regenerated ink cartridge 20 of this embodiment includes:

[0051] Detection step: Detect the original inkjet head 17 and the original chip 16 of the original ink cartridge 10. If they can be used, perform the disassembly step. Some original chips need to be decrypted before they can be used. In addition, they can also be replaced with new chips to add functions such as capacity detection and capacity display.

[0052] Disassembly steps: disassemble the original ink cartridge 10, remove the original cover 12 and the original ink absorbing component 14.

[0053] Cleaning steps: Clean the disassembled parts.

[0054] Modification steps: modify the original box body 11 into the box body 3, modify the original cover 12 into the cover 4, and modify the original ink storage housing 13 into the ink storage housing 5, and then assemble. Specifically, the original ink storage housing 13 is cut and removed from the original box body 11, and the original box body 11 forms a new box body 3; the original cover 12 is replaced with a new integrally formed ink storage housing 5 and cover 4 and installed on the box body 3, and after installation, the bottom end of the ink storage housing 5 is adjacent to the bottom wall 302 of the box body 3. Then, the cover 4 is fixed to the box body 3 by bonding or welding, and the assembly of the regenerated ink cartridge 20 is completed.

[0055] Ink adding steps: fill ink into the second ink storage chamber 34 through the ink adding hole 41, fill ink into the first ink storage chamber 51 through the air guide hole 42, seal the ink adding hole 41 and the air guide hole 42 with a sealing plug after adding ink, and finally package after confirming that the seal is qualified.

[0056] When in use, the user opens the air guide hole 42. During the printing process, only the first ink storage chamber 51 on the regenerated ink cartridge 20 is provided with the air guide hole 42 connected to the external air. Therefore, during the printing process, the ink in the first ink storage chamber 51 will be consumed first. At the same time, the pressure balance between the first ink storage chamber 51 and the second ink storage chamber 34 is destroyed. Therefore, in order to maintain the ink pressure balance, the ink in the second ink storage chamber 34 will be replenished to the first ink storage chamber 51, and the ink in the last two chambers will be consumed in turn. In addition, since the second ink storage chamber 34 has only one connecting hole 52 to connect to the closed space outside, when the printer is not working, the gravity of the ink in the second ink storage chamber 34 is equal to the negative pressure generated above the second ink storage chamber 34, and the ink will not flow to the first ink storage chamber 51, thereby achieving static pressure balance, thereby preventing the ink in the second ink storage chamber 34 from constantly flowing to the first ink storage chamber 51 and then to the inkjet head, causing ink leakage; when the printer is working, as the ink in the second ink storage chamber 34 drops, the air above the second ink storage chamber 34 becomes thinner and generates negative pressure, so that the ink in the second ink storage chamber 34 will not flow into the first ink storage chamber 51 without restraint, and is always in dynamic balance. As the printing process continues, the ink in the second ink storage chamber 34 continues to drop. When the negative pressure of the air above the second ink storage chamber 34 reaches a certain level, the air will enter the second ink storage chamber 34 from the connecting hole 52, and then rise to the upper side of the second ink storage chamber 34, relieving the negative pressure of the air and re-establishing a new pressure balance to ensure the normal supply of ink.

[0057] As can be seen from the above, by remanufacturing the original ink cartridge, the ink storage shell is sealed and connected to the cover, the air guide hole is connected to the first ink storage chamber, and the ink filling hole is connected to the second ink storage chamber. The user can fill the ink into the second ink storage chamber through the ink filling hole, and can also fill the ink into the first ink storage chamber through the air guide hole, thereby greatly expanding the capacity of the ink cartridge and realizing the recycling of the ink cartridge, thereby saving resources and protecting the environment. At the same time, since the regenerated ink cartridge adopts a structure in which the second ink storage chamber is not provided with an ink absorbing component and the first ink storage chamber is provided with a small ink absorbing component, the capacity of the ink in the regenerated ink cartridge will be greatly increased. In addition, since there is no ink absorbing component in the second ink storage chamber that mainly stores ink, the user only needs to add ink to the second ink storage chamber through the ink filling port after use to easily realize the ink filling process. In addition, by sealingly connecting the ink storage shell and the surface cover, the second ink storage chamber is formed into a closed space with only one connecting hole connected to the outside, so that the air above the second ink storage chamber and the ink in the second ink storage chamber form a pressure balance, thereby preventing the ink in the second ink storage chamber from continuously flowing into the first ink storage chamber and then into the inkjet head, causing ink leakage.

[0058] Second Embodiment of the Method for Manufacturing Ink Cartridge and Remanufactured Ink Cartridge:

[0059] As an explanation of the second embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge of the present invention, only the differences from the first embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge described above will be explained below.

[0060] See also Figure 7 and Figure 8 In this embodiment, the cover 24 is provided with an expansion portion 240, which is located between the mounting buckle position 243 and the handle buckle position 244. The expansion portion 240 protrudes upward from the upper surface 245 of the cover 24, and the expansion portion 240 is recessed upward from the lower surface 246 of the cover 24. The ink adding hole 241 and the air guide hole 242 are both provided on the expansion portion 240, and the expansion portion 240 is located directly above the first ink storage cavity 251 and the second ink storage cavity 234, that is, the first ink storage cavity 251 and the second ink storage cavity 234 are both arranged opposite to the expansion portion 240 in the vertical direction. By providing the expansion portion 240 on the cover 24, the capacity of the ink cartridge can be further increased.

[0061] The third embodiment of the method for manufacturing the ink cartridge and the regenerated ink cartridge:

[0062] As an explanation of the third embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge of the present invention, only the differences from the first embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge described above will be explained below.

[0063] In this embodiment, the bottom end of the ink storage housing and the bottom wall of the box body can also be fixedly connected by bonding. In the modification step, before installing the cover, glue is first applied to the bottom wall of the box body or the bottom end of the ink storage housing.

[0064] Fourth embodiment of the method for manufacturing ink cartridge and regenerated ink cartridge:

[0065] As an explanation of the fourth embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge of the present invention, only the differences from the first embodiment of the method for manufacturing an ink cartridge and a regenerated ink cartridge described above will be explained below.

[0066] The ink cartridge of this embodiment also includes a sealing member, which is arranged at the position of the air channel 15 of the original ink cartridge to ensure the airtightness of the second ink storage chamber, so that the second ink storage chamber is connected to the outside only through the connecting hole during the printing process.

[0067] The modification steps include: opening a connecting hole at the bottom of the original ink storage shell, installing a seal at the air channel 15, and the seal and the air channel 15 have an interference fit, the original ink filling hole is used as the air guide hole of the regenerated ink cartridge, and the original air guide hole is used as the ink filling hole of the regenerated ink cartridge.

[0068] In addition, the ink adding hole and the air guiding hole can also be sealed by a sealing film. The bottom end of the ink storage shell can also not contact the bottom wall of the box body, that is, there is a gap between the bottom end of the ink storage shell and the bottom wall of the box body, but the gap cannot be too large, otherwise the ink in the second ink storage chamber will continue to flow into the first ink storage chamber and easily cause ink leakage from the inkjet head. The shapes of the first ink storage chamber and the second ink storage chamber can also be changed as needed, and the number of second ink storage chambers can also be more than two, and multiple second ink storage chambers are separated by spacers, and each second ink storage chamber is provided with a connecting hole connected to the first ink storage chamber. The expansion part can also be arranged only directly above the first ink storage chamber or only directly above the second ink storage chamber. The ink adding hole and the air guiding hole can also be sealed by a sealing film. The above changes can also achieve the purpose of the present invention.

[0069] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications.
