Description

Technical Field

[0001] The present application relates to the field of inkjet printing technology, and in particular to a regenerated ink cartridge and a manufacturing method thereof. Background Art

[0002] Ink cartridges are essential consumables in inkjet printers. When the ink in a cartridge is used up, the user needs to replace it with a new one. For environmental reasons and cost-saving considerations, it's best to recycle the empty cartridge shells.

[0003] Some different ink cartridge models share common structural features, differing only in capacity. Currently, a common problem in the recycled ink cartridge market is the limited availability of high-capacity cartridge shells for recycling. This creates a need to recycle low-capacity cartridge shells into high-capacity remanufactured cartridges. This process requires breaking open specific chambers in the original cartridge shell to accommodate the positioning requirements of the remanufactured model. Furthermore, the connection between these specific chambers and other chambers must be disrupted to prevent ink leakage.

[0004] However, the specific chamber that needs to be destroyed originally serves as a buffer to adapt to changes in the external environment of the ink cartridge. Once such a specific chamber is destroyed, the regenerated ink cartridge loses its original buffering function, posing a safety hazard to the regenerated ink cartridge. Summary of the Invention

[0005] The present application provides a regenerated ink cartridge and a manufacturing method thereof. The regenerated ink cartridge has good buffering performance and high reliability, and can avoid safety hazards.

[0054] As described in the background, in related art, converting a small-capacity ink cartridge into a large-capacity remanufactured ink cartridge requires breaking open a specific chamber within the original cartridge shell to locate the remanufactured cartridge. Simultaneously, the connection between the specific chamber and other chambers (the chambers holding ink) must be broken to prevent ink from entering the specific chamber and preventing ink from leaking out.

[0055] Specifically, a specific chamber in the ink cartridge acts as a buffer. When the ambient temperature or air pressure changes, such as when the temperature rises or the air pressure increases, the ink in other chambers can flow into the specific chamber under the action of pressure, maintaining pressure balance in the ink cartridge and preventing damage to the ink cartridge due to pressure.

[0056] When converting a small-capacity ink cartridge into a larger remanufactured cartridge, the external expansion element has little impact on the cartridge's capacity. However, the destruction of a specific chamber within the remanufactured cartridge removes its buffering function, making it difficult for the remanufactured cartridge to adapt to changing environmental conditions, posing a potential safety hazard.

[0057] In view of this, an embodiment of the present application provides a regenerated ink cartridge and a method for manufacturing the same. The regenerated ink cartridge includes a shell, the interior of the shell is hollow and is separated into a first chamber and a second chamber. The first chamber is used to store ink, and the second chamber is mainly used to perform a buffering function. The first chamber and the second chamber are connected by a channel. By opening a modified hole on the shell, the modified hole is connected to the second chamber, and a first positioning member is provided at the modified hole, and the modified hole is blocked by the first positioning member. The regenerated ink cartridge is docked with the second positioning member on the printer through the first positioning member to meet the positioning requirements of the regenerated ink cartridge in the printer, and the regenerated ink cartridge is stably and reliably installed in the printer. Moreover, since the second chamber is still connected to the first chamber, the second chamber can play its original buffering function, can adapt to changes in external environmental conditions, maintain the internal pressure balance of the regenerated ink cartridge, and prevent the regenerated ink cartridge from leaking ink from the air guide port due to excessive internal pressure, thereby avoiding safety hazards.

[0058] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] Figure 1 This is a schematic diagram of the structure of the regenerated ink cartridge provided in the embodiment of the present application and the installation part in the printer. Figure 1 As shown, an embodiment of the present application provides a regenerated ink cartridge 1 for holding ink. The regenerated ink cartridge 1 is removably mounted on a printer, specifically an inkjet printer. The printer includes a mounting portion 2, which is configured to support multiple or a single regenerated ink cartridge 1. The mounting portion 2 has an opening 21, and the regenerated ink cartridge 1 is removably mounted in the mounting portion 2 along an installation direction P. For example, the opening of the mounting portion may be located at the top of the mounting portion, and the regenerated ink cartridge is installed in the mounting portion along the vertically downward installation direction P.

[0060] The regenerated ink cartridge 1 is provided with an ink outlet 120 and a clamping portion 300, and a chip 400 is mounted on the outer wall of the regenerated ink cartridge 1. The ink outlet 120 can be located at the bottom of the regenerated ink cartridge 1, and the clamping portion 300 can extend from the side wall of the regenerated ink cartridge 1.

[0061] The printer's mounting portion 2 is equipped with an ink supply unit 22, a clamped portion 23, and an electrical contact unit 24. The ink supply unit 22 can be located at the bottom of the mounting portion 2, and the clamped portion 23 can be located on the inner sidewall of the mounting portion 2. The electrical contact unit 24 can include a stylus holder 241 and a stylus 242. One side of the stylus holder 241 can be attached to the inner wall of the mounting portion 2, and the stylus 242 is located on the other side of the stylus holder 241.

[0062] When the remanufactured ink cartridge 1 is installed in the printer's mounting portion 2, the ink in the cartridge 1 flows through the ink outlet 120 to the ink supply portion 22 of the mounting portion 2. The ink supply portion 22 then supplies the ink to the printhead, allowing the ink to be used for printing. The engaging portion 300 of the remanufactured ink cartridge 1 engages with the engaged portion 23 of the mounting portion 2, securing the cartridge 1 to the mounting portion 2 and preventing it from being removed. The chip 400 on the remanufactured ink cartridge 1 has a terminal block that electrically contacts the contact pins 242 on the contact pin holder 241, enabling signal transmission between the remanufactured ink cartridge 1 and the printer.

[0063] Figure 2 A schematic structural diagram of a regenerated ink cartridge provided in an embodiment of the present application from one perspective. Figure 3 for Figure 1 A schematic structural diagram of the regenerated ink cartridge from another perspective.

[0064] Reference Figure 2 and Figure 3As shown, the remanufactured ink cartridge 1 is a remanufactured large-capacity ink cartridge manufactured from an existing small-capacity ink cartridge. The resulting remanufactured ink cartridge 1 is identical in at least its external dimensions to the corresponding large-capacity ink cartridge. This allows the remanufactured ink cartridge 1 to be used in printers equipped with large-capacity ink cartridges. The ink capacity of the remanufactured ink cartridge 1 can be the same as, or slightly larger or smaller than, the corresponding large-capacity ink cartridge.

[0065] Specifically, the remanufactured ink cartridge 1 includes an original ink cartridge 100, which can be a modified small-capacity ink cartridge. In other words, the original ink cartridge 100 in the remanufactured ink cartridge 1 of this embodiment is a modified small-capacity ink cartridge. By modifying the original small-capacity ink cartridge to form the original ink cartridge 100, the remanufactured ink cartridge 1 is compatible with the printer, facilitating positioning of the remanufactured ink cartridge 1 within the printer.

[0066] In some embodiments, based on the large number of used small-capacity ink cartridges, the small-capacity ink cartridge shells can be recycled and remanufactured to serve as the original ink cartridge 100 .

[0067] Continue to refer to Figure 2 or Figure 3 The remanufactured ink cartridge 1 further includes an external body 200, which is connected to the original ink cartridge 100. The original ink cartridge 100 and the external body 200 together constitute the remanufactured ink cartridge 1. By adding the external body 200 to the original ink cartridge 100, the external dimensions of the remanufactured ink cartridge 1 are made the same as those of a high-capacity ink cartridge, making the remanufactured ink cartridge 1 compatible with printers equipped with high-capacity ink cartridges.

[0068] Depending on the user's needs, the external body 200 can be designed as a hollow structure, with a chamber (not shown) inside for holding ink. In this case, the addition of the external body 200 can expand the capacity of the original ink cartridge 100, allowing the remanufactured ink cartridge 1 (capable of holding ink) to have a larger capacity than the original ink cartridge 100. For example, the capacity of the remanufactured ink cartridge 1 can be comparable to that of a corresponding large-capacity ink cartridge.

[0069] Figure 4 for Figure 2 An exploded view of a remanufactured ink cartridge. Figure 5 for Figure 2 Another perspective of the remanufactured ink cartridge.

[0070] Reference Figure 4 and Figure 5As shown, the original ink cartridge 100 can be in a relatively regular rectangular parallelepiped shape, and the regenerated ink cartridge 1 formed after the external body 200 and the original ink cartridge 100 are assembled can also be in a relatively regular rectangular parallelepiped shape (see Figure 1 or Figure 2 ) so that the shape and size of the regenerated ink cartridge 1 match those of the corresponding large-capacity ink cartridge.

[0071] The original ink cartridge 100 includes a housing 110. The housing 110 is hollow and contains a cavity for holding ink. An ink outlet 120 is provided on the housing 110 and communicates with the hollow cavity for holding ink within the housing 110. When the remanufactured ink cartridge 1 is installed in a printer, the ink outlet 120 of the original ink cartridge 100 interfaces with the ink supply unit 22 of the printer, allowing the ink in the original ink cartridge 100 to be supplied from the ink outlet 120 to the ink supply unit 22.

[0072] Combine Figure 4 and Figure 5 As shown, for the convenience of explanation, this embodiment defines the front wall 1101, rear wall 1102, left wall 1103, right wall 1104, top wall 1105 and bottom wall 1106 of the shell 110 of the original ink cartridge 100. The front wall 1101 and the rear wall 1102 of the shell 110 are relatively arranged at the front and rear ends of the shell 110 in the length direction (X direction shown in the figure), the left wall 1103 and the right wall 1104 of the shell 110 are relatively arranged at the left and right ends in the thickness direction (Y direction shown in the figure) of the shell 110, and the top wall 1105 and the bottom wall 1106 of the shell 110 are relatively arranged at the upper and lower ends in the height direction (Z direction shown in the figure) of the shell 110.

[0073] The remanufactured ink cartridge 1 is typically installed vertically in the printer, with the ink outlet 120 of the original ink cartridge 100 positioned on the bottom wall 1106 of the housing 110. The ink in the original ink cartridge 100 flows smoothly out of the ink outlet 120 on the bottom wall 1106 of the housing 110 due to the gravity of the ink and the negative pressure on the printer side.

[0074] Reference Figure 4 or Figure 5 As shown, the external body 200 can be located on the rear side of the original ink cartridge 100. The external body 200 can be attached to the rear wall 1102 of the original ink cartridge 100 to form the remanufactured ink cartridge 1 together with the original ink cartridge 100. Thus, compared to the original ink cartridge 100, under the support of the external body 200, the remanufactured ink cartridge 1 is longer and larger in volume, while maintaining the same thickness as the original ink cartridge 100. The remanufactured ink cartridge 1 has an overall flat box shape, which satisfies the requirements of installation in a printer.

[0075] The external body 200 may include a housing 210, which is the primary structure of the external body 200. The housing 210 is located on the rear side of the original ink cartridge 100 and can fit snugly against the rear wall 1102 of the original ink cartridge 100. The housing 210 is used to increase the length of the remanufactured ink cartridge 1, thereby aligning the dimensions of the remanufactured ink cartridge 1 with those of a corresponding high-capacity ink cartridge.

[0076] The external body 200 may further include a connecting plate 220, which may be connected to the top of the cartridge body 210. The connecting plate 220 is located on the side of the cartridge body 210 facing the original ink cartridge 100 and extends toward the original ink cartridge 100. The connecting plate 220 of the external body 200 may be attached to the top wall 1105 of the original ink cartridge 100.

[0077] Both the housing 210 and the connecting plate 220 of the external body 200 can be connected to the original ink cartridge 100, thereby increasing the connection area between the external body 200 and the original ink cartridge 100 and enhancing the connection strength between the two. Furthermore, the housing 210 and the connecting plate 220 can position the external body 200 from different directions, ensuring the docking accuracy of the external body 200 and the original ink cartridge 100. Furthermore, the combined action of the housing 210 and the connecting plate 220 ensures a stable and secure connection between the external body 200 and the original ink cartridge 100, thereby improving the reliability of the remanufactured ink cartridge 1.

[0078] For example, the box body 210 of the external body 200 and the rear wall 1102 of the original ink cartridge 100 can be welded or bonded. For example, the box body 210 and the rear wall 1102 of the original ink cartridge 100 can be connected using ultrasonic welding. Similarly, the connecting plate 220 of the external body 200 and the top wall 1105 of the original ink cartridge 100 can also be welded or bonded. For example, the connecting plate 220 and the top wall 1105 of the original ink cartridge 100 can be connected using ultrasonic welding.

[0079] Continue to refer to Figure 4 or Figure 5 The original ink cartridge 100 typically has a snap-fit ​​structure on its outer wall, which is compatible with existing printers equipped with small-capacity ink cartridges. Depending on the location and structure of the snap-fit ​​portion 23 in the printer in which the remanufactured ink cartridge 1 is used, the snap-fit ​​structure on the original ink cartridge 100 can be modified or removed and replaced with a new structure to adapt the snap-fit ​​portion 300 of the remanufactured ink cartridge 1 to the printer.

[0080] Specifically, if the position and structure of the clamping portion 23 in the printer used for the remanufactured ink cartridge 1 are the same as those in the printer used for the original ink cartridge 100, the clamping structure on the original ink cartridge 100 can be retained without modifying the clamping structure on the original ink cartridge 100, and the clamping structure on the original ink cartridge 100 can be used as the clamping portion 300 of the remanufactured ink cartridge 1. Figure 4or Figure 5 As shown in , the clamping portion 300 of the remanufactured ink cartridge 1 may be located on the front wall 1101 of the original ink cartridge 100 . For example, the clamping portion 300 may be integrally formed on the front wall 1101 of the original ink cartridge 100 .

[0081] If the position or structure of the engaging portion 23 in the printer used with the remanufactured ink cartridge 1 differs from that of the engaging portion 23 in the printer used with the original ink cartridge 100, the engaging structure on the original ink cartridge 100 can be removed and a engaging structure can be fabricated on the external body 200. For example, a engaging structure can be fabricated on the connecting plate 220 of the external body 200 to serve as the engaging portion 300 of the remanufactured ink cartridge 1. Alternatively, accessories can be provided on the engaging portion 300 to change the engaging position of the engaging portion 300 with the printer's mounting portion 2. Alternatively, the engaging structure on the original ink cartridge 100 can be modified, and a mating structure can be fabricated on the external body 200 (e.g., the connecting plate 220 of the external body 200) to mate with it. The modified engaging structure on the original ink cartridge 100 and the mating structure on the external body 200 together constitute the engaging portion 300 of the remanufactured ink cartridge 1.

[0082] As for the mounting position of the chip 400 on the remanufactured ink cartridge 1, when the position and structure of the chip 400 in the printer used for the remanufactured ink cartridge 1 are compatible with the printer used for the original ink cartridge 100, the mounting position of the chip 400 on the original ink cartridge 100 can remain unchanged. In other words, the chip 400 can still be mounted on the original ink cartridge 100, for example, the chip 400 can be mounted on the front wall 1101 of the original ink cartridge 100 (e.g., Figure 3 shown).

[0083] If the location and configuration of the chip 400 in the printer used with the remanufactured ink cartridge 1 differs from that of the original ink cartridge 100, the mounting position for the chip 400 on the original ink cartridge 100 can be removed. Subsequently, the mounting position can be re-machined on the original ink cartridge 100 or the external body 200 based on the location and configuration of the chip 400 in the printer used with the remanufactured ink cartridge 1, so that the mounting position of the chip 400 matches that of the printer.

[0084] Continue to refer to Figure 4 and Figure 5 In order for the ink in the external body 200 to flow into the original ink cartridge 100, the accommodating cavity of the external body 200 needs to be connected to the hollow cavity for accommodating ink in the original ink cartridge 100. In this case, one of the external body 200 and the original ink cartridge 100 can be provided with a hollow connecting post 211, and the other can be provided with a connecting hole 111. After the external body 200 and the original ink cartridge 100 are assembled together, the connecting post 211 passes through the connecting hole 111 to achieve communication between the external body 200 and the original ink cartridge 100.

[0085] In actual applications, the original ink cartridge 100 before modification is used as a small-capacity ink cartridge, and a protruding structure is usually not designed. Therefore, when the small-capacity ink cartridge is modified into the original ink cartridge 100, a connecting hole 111 can be opened on the small-capacity ink cartridge. In other words, the connecting hole 111 can be provided on the original ink cartridge 100, and the connecting column 211 can be provided on the external body 200. The connecting hole 111 can be provided on the rear wall 1102 of the original ink cartridge 100, and the connecting column 211 can be provided on the side wall of the external body 200 that is in contact with the rear wall 1102 of the original ink cartridge 100. The connecting column 211 protrudes from the outer wall of the external body 200, and the connecting column 211 is connected to the accommodating cavity in the external body 200.

[0086] Of course, a hollow connecting post 211 may also be provided on the original ink cartridge 100, and a communication hole 111 may be provided on the external body 200, so that the connecting post 211 on the original ink cartridge 100 passes through the communication hole 111 on the external body 200, thereby achieving communication between the external body 200 and the original ink cartridge 100. This embodiment is not limited to this. The following description will take the example of providing the communication hole 111 on the original ink cartridge 100 and providing the hollow connecting post 211 on the external body 200 as an example.

[0087] In some embodiments, there may be only one connection point between the external body 200 and the original ink cartridge 100. In other words, there may be only one connecting post 211 on the external body 200 and only one connecting hole 111 on the original ink cartridge 100. In this case, the connection point between the external body 200 and the original ink cartridge 100 serves as an ink passage, allowing ink in the accommodating cavity of the external body 200 to flow into the original ink cartridge 100.

[0088] In addition, the external body 200 may also be provided with an air inlet 215 (see Figure 3 As shown), air can enter the accommodating chamber from the air inlet 215 to maintain the air pressure balance in the accommodating chamber and guide the ink into the original ink cartridge 100. At the same time, the original ink cartridge 100 before modification is used as a small-capacity ink cartridge, and the small-capacity ink cartridge is usually provided with an air inlet 119 (see Figure 8 As shown), to ensure that the internal air pressure of the small-capacity ink cartridge is balanced. To this end, when the small-capacity ink cartridge is converted into the original ink cartridge 100, the air inlet 119 on the housing 110 of the original ink cartridge 100 can be blocked.

[0089] In other embodiments, the external body 200 and the original ink cartridge 100 may have two connecting points. In other words, the external body 200 is provided with two connecting posts 211, and the original ink cartridge 100 is provided with two connecting holes 111, and the two connecting posts 211 pass through the two connecting holes 111, respectively. In this case, one connecting point between the external body 200 and the original ink cartridge 100 serves as the passage for ink, and the other connecting point between the external body 200 and the original ink cartridge 100 serves as the circulation point for air.

[0090] The connecting portion, serving as the ink passage, can be located at the bottom of the accommodating chamber of the external body 200, allowing the ink in the accommodating chamber of the external body 200 to flow smoothly and completely into the original ink cartridge 100. The connecting portion, serving as the air circulation portion, can be located near the top of the accommodating chamber of the external body 200. Air can flow into the accommodating chamber of the external body 200 through the air inlet hole 119 in the original ink cartridge 100 and this connecting portion, thereby ensuring balanced air pressure within the remanufactured ink cartridge 1.

[0091] In addition, a sealing member 112 may be provided in the communicating hole 111 on the original ink cartridge 100 . The sealing member 112 may be a flexible member such as a silicone member or a rubber member.

[0093] Reference Figure 6 and Figure 7 As shown, the housing 110 of the original ink cartridge 100 may include a main housing 113 and a cover 114. The main housing 113 and the cover 114 together form a hollow cavity to facilitate the processing and manufacturing of the housing 110. The housing 110 may be divided into a first chamber 115 and a second chamber 116, and the first chamber 115 and the second chamber 116 may be connected by a channel.

[0094] The first chamber 115 serves as the primary chamber of the original ink cartridge 100 and is used to store ink. An ink outlet 120 on the bottom wall 1106 of the housing 110 can be positioned corresponding to the first chamber 115 . The ink outlet 120 communicates with the first chamber 115 to allow ink within the first chamber 115 to flow out through the ink outlet 120 .

[0095] The second chamber 116 is a specific chamber of the original ink cartridge 100, and is used to act as a buffer to maintain the internal air pressure balance of the original ink cartridge 100. Specifically, when the ambient temperature or external air pressure is abnormal, for example, when the ambient temperature rises and the ink in the first chamber 115 expands due to heat, or when the external air pressure increases and squeezes the ink in the first chamber 115, the ink in the first chamber 115 can flow into the second chamber 116, thereby preventing the ink in the first chamber 115 from exerting excessive pressure on the housing 110, preventing the housing 110 from being damaged by the pressure, and avoiding the risk of ink leakage in the original ink cartridge 100, thereby ensuring the safety of the original ink cartridge 100.

[0096] When the ambient temperature and external air pressure return to normal, under the action of the internal air pressure of the original ink cartridge 100 and the passage connecting the first chamber 115 and the second chamber 116, the ink in the second chamber 116 can flow back into the first chamber 115, so that the ink in the original ink cartridge 100 can be fully utilized by the printer, avoiding ink waste.

[0097] Reference Figure 7 As shown, the first chamber 115 and the second chamber 116 in the housing 110 can be arranged side by side along the front-to-back direction of the housing 110. The first chamber 115 can be located near the rear wall 1102 of the housing 110, and the second chamber 116 can be located near the front wall 1101 of the housing 110. In this way, the communication hole 111 located on the rear wall 1102 of the housing 110 can communicate with the first chamber 115 in the housing 110. The external body 200 located at the rear side of the housing 110 has its box body 210 located on the side where the first chamber 115 is located. The accommodating cavity in the box body 210 can communicate with the first chamber 115 in the housing 110, so that the ink in the external body 200 can flow into the first chamber 115 of the original ink cartridge 100.

[0098] Reference Figure 8 As shown, the channel connecting the first chamber 115 and the second chamber 116 can be a channel groove 117 provided on the right wall 1104 of the housing 110. The channel groove 117 can be located on the outer wall surface of the right wall 1104 of the housing 110, or in other words, the channel groove 117 is located on the outer wall surface of the main shell 113 facing away from the cover body 114. The two ends of the channel groove 117 extend to the locations of the first chamber 115 and the second chamber 116 respectively, and the two ends of the channel groove 117 form channel openings 1171. The channel openings 1171 at the two ends of the channel groove 117 are respectively connected to the first chamber 115 and the second chamber 116, so that the first chamber 115 and the second chamber 116 are connected through the channel groove 117.

[0099] Since the channel groove 117 is provided on the outer wall of the housing 110, the right wall 1104 of the housing 110 may be covered with a sealing layer 118 to prevent ink from overflowing from the channel groove 117. The sealing layer 118 covers the side of the main housing 113 facing away from the cover 114. The sealing layer 118 covers the channel groove 117. The sealing layer 118 and the channel groove 117 together form a sealed channel to prevent ink from overflowing.

[0100] Figure 9 A schematic diagram of the structure of the external body provided in an embodiment of the present application. Figure 10 for Figure 9 The decomposition diagram of the external body in . Figure 9 and Figure 10As shown, similar to the shell 110 of the original ink cartridge 100, the box body 210 of the external body 200 can include a main box 212 and a cover plate 213. The main box 212 and the cover plate 213 together form a receiving cavity 214 to facilitate the processing and manufacturing of the box body 210. The connecting plate 220 can be connected to the top wall 1105 of the main box 212. For example, the connecting plate 220 can be integrally formed on the top wall 1105 of the main box 212.

[0101] Figure 11 This is a schematic structural diagram of the original ink cartridge main shell provided in an embodiment of the present application. Figure 12 for Figure 11 The exploded structure diagram of the original ink cartridge main shell. Figure 11 and Figure 12 As shown, in order to make the regenerated ink cartridge 1 adapt to the installation structure in the printer and stably and reliably install the regenerated ink cartridge 1 in the printer, in this embodiment, after the small-capacity ink cartridge is converted into the original ink cartridge 100, a positioning structure is formed on the original ink cartridge 100. The regenerated ink cartridge 1 is positioned in the printer by utilizing the cooperation between the positioning structure on the original ink cartridge 100 and the printer.

[0102] Specifically, a modification hole 1121 is defined in the housing 110 of the original ink cartridge 100, and a first positioning member 130 is disposed at the modification hole 1121. The first positioning member 130 is used to position the remanufactured ink cartridge 1. Correspondingly, a second positioning member is provided in the printer, and the first positioning member 130 interfaces with the second positioning member to position the remanufactured ink cartridge 1.

[0103] As previously mentioned, the remanufactured ink cartridge 1 is typically installed vertically in the printer, typically using the bottom of the remanufactured ink cartridge 1 to engage with the printer to position the remanufactured ink cartridge 1. To this end, the modified hole 1121 can be provided on the bottom wall 1106 of the housing 110 of the original ink cartridge 100. Accordingly, the first positioning member 130 is also connected to the bottom wall 1106 of the housing 110.

[0104] Based on the position of the second positioning member in the printer, the first positioning member 130 on the remanufactured ink cartridge 1 typically corresponds to the second chamber 116 of the original ink cartridge 100. In this case, the remanufactured hole 1121 defined in the bottom wall 1106 of the housing 110 of the original ink cartridge 100 can be located where the second chamber 116 is located, allowing the remanufactured hole 1121 to communicate with the second chamber 116. The first positioning member 130 is positioned at the remanufactured hole 1121 and can block the remanufactured hole 1121. In other words, the first positioning member 130 can seal the second chamber 116.

[0105] In this embodiment, a modified hole 1121 communicating with the second chamber 116 is formed in the housing 110 of the original ink cartridge 100. A first positioning member 130 is provided at the modified hole 1121 to facilitate positioning of the remanufactured ink cartridge 1. Because the first positioning member 130 blocks the modified hole 1121, the second chamber 116 remains sealed, preventing ink leakage from the second chamber 116.

[0106] This arrangement eliminates the need to cut off the connection between the second chamber 116 and the first chamber 115 to prevent ink leakage. In other words, the second chamber 116 and the first chamber 115 can still remain connected. Specifically, the passage connecting the second chamber 116 and the first chamber 115 can remain intact without needing to be blocked. This allows the second chamber 116 to still perform its original buffering function, allowing the original ink cartridge 100 to adapt to changes in external environmental conditions and maintain internal pressure balance.

[0107] Specifically, when the ambient temperature or external air pressure is abnormal, the ink in the first chamber 115 can still flow into the second chamber 116 through the channel. When the ambient temperature and external air pressure return to normal, the ink in the second chamber 116 can flow back into the first chamber 115. This prevents excessive internal pressure in the original ink cartridge 100 from causing ink leakage, avoids safety hazards in the remanufactured ink cartridge 1, and improves the reliability and safety of the remanufactured ink cartridge 1.

[0108] Combine Figure 11 and Figure 12 As shown, the first positioning member 130 may include a positioning portion 131, which is configured to cooperate with a second positioning member in the printer to position the remanufactured ink cartridge 1. For example, taking the second positioning member in the printer as a positioning protrusion, the positioning portion 131 of the first positioning member 130 may have a positioning groove 1311, with the notch of the positioning groove 1311 facing the second positioning member. The second positioning member is inserted into the positioning groove 1311 of the positioning portion 131. The positioning portion 131 restrains the second positioning member, thereby positioning the remanufactured ink cartridge 1 in the printer.

[0109] As for the first positioning member 130 itself, the positioning portion 131 of the first positioning member 130 can generally be a cylindrical structure, with one end of the positioning portion 131 being open and the other end of the positioning portion 131 being closed to form a positioning groove 1311 in the positioning portion 131, and when the first positioning member 130 is arranged at the modified hole 1121 on the shell 110, the positioning portion 131 of the first positioning member 130 can block the modified hole 1121 to seal the second chamber 116 in the shell 110.

[0110] In the first positioning member 130, the positioning portion 131 is open at one end facing the second positioning member of the printer, and this end forms the opening of the positioning slot 1311. In other words, the positioning portion 131 has the opening of the positioning slot 1311 formed at the end facing away from the housing 110. Thus, the opening of the positioning slot 1311 in the positioning portion 131 faces the second positioning member of the printer, making it easier for the second positioning member to be inserted into the positioning slot 1311 of the positioning portion 131.

[0111] The positioning portion 131 of the first positioning member 130 can at least partially extend into the second chamber 116. In other words, the positioning portion 131 of the first positioning member 130 can pass through the modified hole 1121 in the bottom wall 1106 of the housing 110, so that the positioning portion 131 is at least partially located within the second chamber 116. The second chamber 116 can be used to accommodate at least part of the structure of the first positioning member 130, reducing the space additionally occupied by the first positioning member 130, thereby simplifying and regularizing the appearance of the remanufactured ink cartridge 1.

[0112] Furthermore, the positioning groove 1311 in the positioning portion 131 of the first positioning member 130 may extend along the installation direction of the housing 110 of the original ink cartridge 100. For example, the positioning groove 1311 in the positioning portion 131 may extend along the height direction of the housing 110. Correspondingly, the positioning protrusion serving as the second positioning member in the printer may also extend along the installation direction of the original ink cartridge 100. For example, the second positioning member may protrude vertically on the inner bottom wall 1106 of the printer.

[0113] When installing the remanufactured ink cartridge 1 into the printer, it should be installed vertically downward. The second positioning member in the printer is inserted into the positioning groove 1311 of the first positioning member 130 on the bottom wall 1106 of the remanufactured ink cartridge 1, and the ink outlet 120 on the bottom wall 1106 of the remanufactured ink cartridge 1 is aligned with the ink outlet pin in the printer. Simultaneously, the engaging portion 300 on the remanufactured ink cartridge 1 is engaged with the engaged portion 23 in the printer to secure the remanufactured ink cartridge 1 in place and securely connect the remanufactured ink cartridge 1 to the printer.

[0114] Continue to refer to Figure 11 and Figure 12 In this embodiment, the first positioning member 130 may further include a coupling portion 132, which is connected to the positioning portion 131. The coupling portion 132 and the positioning portion 131 together constitute the first positioning member 130. For example, the coupling portion 132 may be integrally formed on the positioning portion 131, or in other words, the first positioning member 130 may be an integrally formed member.

[0115] By connecting the engaging portion 132 to the positioning portion 131, the engaging portion 132 can be connected to the bottom wall 1106 of the housing 110 of the original ink cartridge 100, thereby connecting and fixing the first positioning member 130 to the housing 110. A large contact area can be formed between the engaging portion 132 and the bottom wall 1106 of the housing 110 to increase the connection strength between the first positioning member 130 and the housing 110 and enhance the reliability of the first positioning member 130. For example, the engaging portion 132 and the bottom wall 1106 of the housing 110 can be welded, bonded, or connected by screws, bolts, or other fasteners.

[0116] Of course, as long as the reliability of the connection between the first positioning member 130 and the housing 110 is ensured, the first positioning member 130 may also include only the positioning portion 131, with the outer peripheral wall of the positioning portion 131 connected to the wall of the modified hole 1121 on the bottom wall 1106 of the housing 110 to achieve the connection between the first positioning member 130 and the housing 110. This embodiment does not impose any specific limitations on this. The following description will be based on an example in which the first positioning member 130 includes the engaging portion 132, and the engaging portion 132 is connected to the bottom wall 1106 of the housing 110.

[0117] In some embodiments, the engaging portion 132 of the first positioning member 130 may be connected to the bottom end of the positioning portion 131. In other words, the engaging portion 132 is connected to the end of the positioning portion 131 facing away from the housing 110. When the first positioning member 130 is connected to the bottom wall 1106 of the housing 110, the positioning portion 131 of the first positioning member 130 may be entirely located within the second cavity 116, thereby further reducing the portion of the first positioning member 130 located outside the housing 110.

[0118] Furthermore, the engaging portion 132 can be disposed around the outer periphery of the notch of the positioning slot 1311. The engaging portion 132 is equivalent to a flange structure formed around the outer periphery of the end of the positioning portion 131. The engaging portion 132 does not obstruct the notch of the positioning slot 1311, ensuring smooth insertion of the second positioning member in the printer into the positioning slot 1311 of the first positioning member 130. The engaging portion 132 is in close contact with the bottom wall 1106 of the housing 110, ensuring sufficient contact area between the two, thereby ensuring the connection strength between the first connector and the housing 110.

[0119] As an example, the joint portion 132 can be attached to the outer wall surface of the bottom wall 1106 of the shell 110. At this time, the positioning portion 131 of the first positioning member 130 is located in the second chamber 116 of the original ink cartridge 100, and the joint portion 132 of the first positioning member 130 is exposed on the outer wall surface of the shell 110 (such as Figure 2With this arrangement, when assembling the first positioning member 130, the positioning portion 131 of the first positioning member 130 can be inserted into the second chamber 116 from outside the housing 110, facilitating assembly of the first positioning member 130. Furthermore, the engagement portion 132 of the first positioning member 130, abutted against the bottom wall 1106 of the housing 110, can limit the position of the first positioning member 130, thereby improving the connection accuracy and reliability of the first positioning member 130.

[0120] As another example, if sufficient installation space is available, the engaging portion 132 can be attached to the inner surface of the bottom wall 1106 of the housing 110. In this case, the first positioning member 130 is entirely located within the second chamber 116 of the original ink cartridge 100, with no exposed portion of the first positioning member 130. This arrangement enhances the appearance of the remanufactured ink cartridge 1, making it more concise and elegant.

[0121] The embodiment of the present application also provides a method for manufacturing a regenerated ink cartridge 1 , which is used to manufacture the aforementioned regenerated ink cartridge 1 .

[0122] Figure 13 This is a flowchart of the steps of the method for making a regenerated ink cartridge provided in an embodiment of the present application. Figure 13 As shown, the production method includes the following steps:

[0123] S100 , providing the shell 110 of the original ink cartridge 100 .

[0124] First, the shell 110 of the original ink cartridge 100 is provided. The shell 110 can be an empty shell of a corresponding small-capacity ink cartridge before modification. Before the shell 110 of the original ink cartridge 100 is modified, the shell 110 is subjected to pre-processing steps such as sorting, cleaning, and drying.

[0125] The housing 110 of the original ink cartridge 100 is divided into a first chamber 115 and a second chamber 116, which are connected by a channel. The first chamber 115 is used to store ink.

[0126] The second chamber 116 serves as a special chamber to perform a buffering function.

[0127] S200 , a reforming hole 1121 is opened on the housing 110 , and the reforming hole 1121 is communicated with the second chamber 116 .

[0128] After the shell 110 of the original ink cartridge 100 is prepared, a modification hole 1121 is opened on the shell 110. The modification hole 1121 can be opened on the bottom wall 1106 of the shell 110, and the modification hole 1121 is located at the position where the second chamber 116 is located, and the modification hole 1121 can be connected to the second chamber 116.

[0129] S300 , providing a first positioning member 130 , and disposing the first positioning member 130 at the modified hole 1121 to block the modified hole 1121 .

[0130] After the modification hole 1121 is formed in the housing 110, the prepared first positioning member 130 is placed at the modification hole 1121 and connected to the housing 110. For example, the first positioning member 130 is welded, bonded, or connected to the bottom wall 1106 of the housing 110 using screws, bolts, or other fasteners. The first positioning member 130 blocks the modification hole 1121, thereby sealing the second chamber 116 in the housing 110.

[0131] It can be understood that the manufacturing method of the regenerated ink cartridge 1 also includes: opening a connecting hole 111 on the shell 110 of the original ink cartridge 100, providing an external body 200, and assembling the external body 200 with the original ink cartridge 100, so that the connecting column 211 on the external body 200 passes through the connecting hole 111 on the original ink cartridge 100, etc.

[0132] The communicating hole 111 can be first formed in the housing 110 of the original ink cartridge 100, and after the original ink cartridge 100 and the external body 200 are assembled together, the modified hole 1121 can be formed in the housing 110, and the first positioning member 130 can be connected to the modified hole 1121. Alternatively, the modified hole 1121 can be first formed in the housing 110 of the original ink cartridge 100, and after the first positioning member 130 is connected to the modified hole 1121, the original ink cartridge 100 and the external body 200 can be assembled together. This embodiment is not limited to this.

[0133] In addition, when the snap-fit ​​structure of the original ink cartridge 100 needs to be modified, the method for manufacturing the remanufactured ink cartridge 1 further includes modifying the snap-fit ​​structure of the original ink cartridge 100. For example, a heightened structure may be added to the snap-fit ​​structure of the original ink cartridge 100, and the heightened structure may be located at the protrusion of the snap-fit ​​structure of the first chamber 115.

[0134] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0135] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
