[0049] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] In the description of this application, unless otherwise specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0051] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described from the perspectives shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also indirectly connected to the other element "on" or "under" through an intermediate element.

[0052] Reference Figure 1 As shown, Figure 1 A three-dimensional diagram of the ink cartridge provided in the embodiment of the present application. The original ink cartridge 1 is the ink cartridge before regeneration. The original ink cartridge 1 is manufactured by an inkjet printer manufacturer. In order to adapt to different markets and meet the needs of different customers, inkjet printer manufacturers will consider the universalization of molds / mold accessories when designing and manufacturing to maximize the utilization rate of production molds. Usually, the structures of large-capacity ink cartridges and small-capacity ink cartridges (for example, the original ink cartridge 1 is a small-capacity ink cartridge, but its structure is basically the same as that of the large-capacity ink cartridge) are basically the same, but the size is different.

[0053] For remanufactured ink cartridges, small-capacity cartridges (e.g., original ink cartridge 1) contain less ink, are used more frequently, or are more commonly used in the market. This leads to a higher number of empty cartridges of these small-capacity models on the remanufactured market, while large-capacity cartridges are less common. Remanufacturers struggle to collect enough empty cartridges of large-capacity models to meet the market demand for these remanufactured cartridges. Remanufacturers face a technical challenge in converting small-capacity cartridges into large-capacity cartridges.

[0054] Continue to refer to Figure 1As shown, the original ink cartridge 1 includes an ink cartridge body 11, which is roughly a box-shaped structure and has an ink cavity (not shown in the figure) inside. The ink cavity is used to hold ink. Furthermore, the ink cartridge body 11 has a first side 111, a second side 112, a third side 113, a fourth side 114, a bottom surface 115 and a top surface 116. A three-dimensional rectangular coordinate system with an X axis, a Y axis and a Z axis is established, and the X axis, the Y axis and the Z axis are perpendicular to each other. The first side 111 is arranged opposite to the second side 112, the third side 113 is arranged opposite to the fourth side 114, and the bottom surface 115 is arranged opposite to the top surface 116. The first side 111, the second side 112, the third side 113 and the fourth side 114 are adjacent to and intersect with the bottom surface 115 and the top surface 116, forming an ink cavity that can be used to hold ink. The direction from the top surface 116 to the bottom surface 115 is the +Z axis direction, the direction from the second side surface 112 to the first side surface 111 is the +Y axis direction, and the direction from the fourth side surface 114 to the third side surface 113 is the +X axis direction.

[0055] Specifically, the bottom surface 115 is provided with an ink outlet 117, and the original ink cartridge 1 further includes a handle 12 (original handle) and an ink amount detection component 13 ( Figure 3 (shown in the figure). The ink level detection component 13 is connected to the bottom surface 115, and the handle 12 is connected to the first side surface 111. The handle 12 has a locking portion 121, and the locking portion 121 has a locking surface 121a. When the original ink cartridge 1 is installed in a corresponding printing device, the locking portion 121 engages with the printing device. The locking surface 121a of the locking portion 121 abuts the printing device, preventing the original ink cartridge 1 from being separated from the printing device.

[0056] Furthermore, some protrusions are provided on the second side surface 112. These protrusions can be: fingerprints or finger pressure points that facilitate the user to pick up the original ink cartridge 1; or non-standard identification protrusions that are used to match the recessed portion of the printing device when the original ink cartridge 1 is installed on the corresponding printing device to identify the color, ink volume and other information of the ink stored in the ink cartridge body 11.

[0057] Reference Figure 2 、 Figure 3 As shown, Figure 2 A three-dimensional diagram of a regenerated ink cartridge provided in an embodiment of the present application, Figure 3A three-dimensional view of a regenerated ink cartridge from another perspective provided in an embodiment of the present application. The embodiment of the present application discloses a regenerated ink cartridge 100, which is suitable for use with different printing devices, unlike the original ink cartridge 1 described above. The X-axis, Y-axis, and Z-axis of the three-dimensional rectangular coordinate system of the regenerated ink cartridge 100 coincide with those of the original ink cartridge 1. The regenerated ink cartridge 100 comprises the original ink cartridge 1, an external body 2, and a chip 3. The chip 3 is connected to a first side 111. The chip 3 may have been rewritten with the ink volume or model number, or it may have been rewritten by replacing the wafer information on the original chip. The external body 2 is connected to a second side 112 of the original ink cartridge 1, and at least a portion of the external body 2 is located on the bottom surface 115 of the original ink cartridge 1. The height of the regenerated ink cartridge 100 in the second direction is greater than that of the original ink cartridge 1 in the second direction. Specifically, the external body 2 elevates the regenerated ink cartridge 100, causing the bottom surface 115 of the original ink cartridge 1 to be higher than the bottom surface 105 of the regenerated ink cartridge 100. At least a portion of the external body 2 is disposed on the bottom surface 115 and the second side surface 112 of the ink cartridge body 11, such that the width of the remanufactured ink cartridge 100 in a first direction is greater than the width of the original ink cartridge 1 in the first direction. The first direction refers to the direction from the second side surface 102 to the first side surface 101, and the second direction refers to the direction from the top surface 106 to the bottom surface 105.

[0058] This application utilizes an external body 2 connected to the second side surface 112 of the ink cartridge body 11, with at least a portion of the external body 2 located on the bottom surface 115 of the ink cartridge body 11. This allows the height of the regenerated ink cartridge 100 in the second direction to be greater than the height of the ink cartridge body 11, thereby regenerating a small-capacity original ink cartridge 1 into a large-capacity regenerated ink cartridge 100. The width of the regenerated ink cartridge 100 in the first direction is greater than the width of the original ink cartridge 1 in the first direction, and the height of the regenerated ink cartridge 100 in the second direction is greater than the height of the original ink cartridge 1 in the second direction. In other words, regenerating a small-capacity original ink cartridge 1 into a large-capacity regenerated ink cartridge 100 solves the problem of empty large-capacity ink cartridges not meeting market demand.

[0059] Specifically, the remanufactured ink cartridge 100 has a box-like structure, having a first side surface 101, a second side surface 102, a third side surface 103, a fourth side surface 104, a bottom surface 105, and a top surface 106. The first side surface 101 is disposed opposite the second side surface 102, the third side surface 103 is disposed opposite the fourth side surface 104, and the bottom surface 105 is disposed opposite the top surface 106. The ink outlet 117 is disposed protruding from the bottom surface 105.

[0060] Furthermore, the bottom surface 105 of the remanufactured ink cartridge 100 is parallel to the bottom surface 115 of the original ink cartridge 1 .

[0061] Furthermore, the external body 2 is disposed on the -Y-axis side and -Z-axis side of the ink cartridge body 11. That is, at least a portion of the external body 2 is located on the second side surface 112 and bottom surface 115 of the ink cartridge body 11. This allows the remanufactured ink cartridge 100 to be longer in the Y-axis direction and taller in the Z-axis direction than the original ink cartridge 1. Preferably, the protrusion on the second side surface 112 of the ink cartridge body 11 can be cut away before the external body 2 is attached to the second side surface 112 of the ink cartridge body 11 to form the remanufactured ink cartridge 100. A distance is provided between the bottom surface 105 of the remanufactured ink cartridge 100 and the bottom surface 115 of the ink cartridge body 11, and a distance is provided between the second side surface 102 of the remanufactured ink cartridge 100 and the second side surface 112 of the ink cartridge body 11. Furthermore, the distance between the bottom surface 105 of the regenerated ink cartridge 100 and the bottom surface 115 of the ink cartridge body 11 is a first distance D, and the distance between the second side surface 102 of the regenerated ink cartridge 100 and the second side surface 112 of the ink cartridge body 11 is a second distance T.

[0062] Reference Figure 4 As shown, Figure 4 A partially disassembled schematic diagram of a regenerated ink cartridge provided in an embodiment of the present application. The external body 2 includes a main body 21, a connector 22, and a sealing member 23. The main body 21 is arranged on the second side surface 112 of the ink cartridge body 11, and a accommodating chamber 211 is provided in the external body 2. The sealing member 23 is sealedly connected to the side wall of the accommodating chamber 211, so that the accommodating chamber 211 forms a sealed cavity that can be used to accommodate ink, to ensure that if ink is stored in the external body 2, there will be no leakage of ink. In addition, a flow path can also be provided on the outer surface of the external body 2 and sealed by thin film welding. The connecting member 22 is connected to the main body 21 and is located on the bottom surface 115 of the ink cartridge body 11, so that the regenerated ink cartridge 100 is longer in the Y-axis direction and higher in the Z-axis direction than the original ink cartridge 1.

[0063] By setting up the external body 2, the present application can regenerate a small-capacity ink cartridge into a large-capacity ink cartridge, thereby solving the problem that the empty shells of large-capacity ink cartridges cannot meet the market demand for the large-capacity regenerated ink cartridges.

[0064] Also refer to Figure 4 、 Figure 5 As shown, Figure 5This is a cross-sectional schematic diagram of a regenerated ink cartridge provided in an embodiment of the present application. The external body 2 also includes two connecting pieces 24, one end of each of the connecting pieces 24 being connected to the main body 21, and the other end of each of the connecting pieces 24 being connected to the ink cartridge body 11, so that the accommodating cavity of the external body 2 is connected to the ink cavity of the ink cartridge body 11. When ink is stored in the external body 2, the ink can flow into the ink cavity of the ink cartridge body 11 through the connecting piece 24, and then the ink is supplied to the printing device 90 through the valve 14 and the ink outlet 117. The present application uses the provision of the connecting piece 24 to enable the ink stored in the external body 2 to flow into the ink cartridge body 11, thereby increasing the amount of ink in the regenerated ink cartridge 100. The amount of ink that can be stored in the regenerated ink cartridge 100 is greater than that of the original ink cartridge 1, thereby reducing the number of times the ink cartridge is replaced and avoiding environmental pollution and waste of resources.

[0065] In this embodiment, the external body 2 includes two connecting pieces 24, so that it communicates with the ink cartridge body 11 through the two connecting pieces 24. It is understood that in other embodiments, the external body 2 may include only one connecting piece 24, or the external body 2 may include three or more connecting pieces 24. Alternatively, the external body 2 may not be provided with a connecting piece because the external body 2 does not store ink, and the remanufactured ink cartridge 100 may also be installed in a corresponding printing device 90.

[0066] Furthermore, the bottom surface 105 of the remanufactured ink cartridge 100 is separated from the bottom surface 115 of the cartridge body 11 by a connector 22 (the height of the connector 22 in the Z-axis direction is a first distance D). The top surface 106 is partially the top surface 116 of the cartridge body 11 and partially the top surface of the external body 2. The second side surface 102 is separated from the second side surface 112 of the cartridge body 11 by the main body 21 of the external body 2 (the length of the main body 21 in the Y-axis direction is a second distance T). The first side surface 101 of the remanufactured ink cartridge 100 is the first side surface 111 of the cartridge body 11. The third side surface 103 is partially the third side surface 113 of the cartridge body 11 and partially the side surface of the external body 2. The fourth side surface 104 is partially the fourth side surface 114 of the cartridge body 11 and partially the side surface of the external body 2. Furthermore, the width of the remanufactured ink cartridge 100 in the X-axis direction is consistent with the width of the cartridge body 11 in the X-axis direction. The second side surface 102 may further be provided with a protrusion 102 a , which may be a fingerprint or a finger pressure point for the user to easily pick up the regenerated ink cartridge 100 .

[0067] Continue to participate Figure 3 As shown, the regenerated ink cartridge 100 further includes a sealing film 7 , which is disposed on the bottom end surface 117 a of the ink outlet 117 of the regenerated ink cartridge 100 to prevent ink leakage during transportation of the regenerated ink cartridge 100 .

[0068] In some cases, the distance between the snap-fit ​​position 121 of the handle 12 of the remanufactured ink cartridge 100 and the chip 3 is inconsistent with the distance between the snap-fit ​​position 121 of the handle 12 of the original ink cartridge 1 and the original chip. Even after using the above-mentioned recycling method, the remanufactured ink cartridge 100 cannot be used on the corresponding printing device. For example, the snap-fit ​​position 121 on the handle 12 can be engaged with the components on the corresponding printing device, but the chip 3 cannot be engaged with the contact pins on the corresponding printing device, which will cause the remanufactured ink cartridge 100 to be unable to be used normally on the corresponding printing device.

[0069] Furthermore, the remanufactured ink cartridge 100 also includes a chip holder 4. The chip holder 4 is disposed on the first side surface 101 of the remanufactured ink cartridge 100, and the chip 3 is mounted on the chip holder 4. Specifically, the chip 3 is positioned on the first side surface 101 via the chip holder 4. The present application utilizes the chip holder 4 to adjust the position of the chip 3 on the remanufactured ink cartridge 100, thereby resolving the technical issue of the mismatch between the grip engagement position of the remanufactured ink cartridge 100 and the spacing between the chips.

[0070] In this embodiment, the chip rack 4 is independently provided with the external body 2. It is understood that in other embodiments, the chip rack 4 can also be integrally formed with the external body 2 (ie, the chip rack 4 can be regarded as a part of the external body 2).

[0071] Continue to refer to Figure 5 As shown, Figure 5 The printer portion is represented by dashed lines. When the remanufactured ink cartridge 100 is installed in the corresponding printing device 90, the ink outlet 117 engages with the ink supply needle 91 of the corresponding printing device 90, and the latching portion 121 engages with the printing device 90. Specifically, the latching surface 121a of the latching portion 121 abuts the engaged surface 91a of the corresponding printing device 90, preventing the remanufactured ink cartridge 100 from being removed from the printing device. The chip 3 engages with the contact pins of the corresponding printing device 90 to form an electrical connection. Ink can be supplied to the print head of the printing device through the valve 14, ink outlet 117, and ink supply needle 91, preparing for printing.

[0072] Continue to refer to Figure 3 As shown, the bottom of the external body 2 also has a first through-hole 201 and a second through-hole 202. The ink outlet 117 protrudes from the bottom surface 105 through the first through-hole 201. The ink level detection component 13 is exposed on the bottom surface 105 through the second through-hole 202. When the remanufactured ink cartridge 100 is installed in the corresponding printing device 90, the ink level detection component 13 can function normally. Furthermore, the first through-hole 201 can cover the ink outlet 117, thereby forming an integral structure with the chip holder 4.

[0073] If the ink level detection component 13 is positioned near the side of the ink cartridge in the Y-axis direction, the user's hand may contact the side in the Y-axis direction, potentially introducing foreign matter (e.g., ink, dust, etc.) into the ink cartridge and contaminating the ink level detection component 13. The present application disposes the ink level detection component 13 in the middle area between the first side surface 101 and the second side surface 102. That is, the ink level detection component 13 is positioned in the middle area of ​​the remanufactured ink cartridge 100 in the first direction (the Y-axis direction). This reduces the likelihood of the ink level detection component 13 being contaminated by foreign matter (e.g., ink, dust, etc.). Even if the user's hand carries foreign matter, the ink level detection component 13 will not be contaminated. Furthermore, the ink level detection component 13 is positioned within the second through hole 202 on the bottom surface 105, further reducing the likelihood of the ink level detection component 13 being contaminated by foreign matter (e.g., ink, dust, etc.).

[0074] It is understandable that in other embodiments, the external body 2 may not have the second through hole 202 , but in this case the ink amount detection component 13 cannot perform its ink amount detection function.

[0075] Continue to refer to Figure 3 As shown, the bottom surface 105 of the regenerated ink cartridge 100 also has two recesses: a first recess 204 and a second recess 205. The first recess 204 and the second recess 205 are located near the second side surface 102 and the first side surface 101, respectively. Specifically, the first recess 204 and the second recess 205 are located on either side of the regenerated ink cartridge 100 in the first direction (the Y-axis direction). The two recesses can be inserted into the two protrusions of the printing device to achieve a mating and limiting effect. When the regenerated ink cartridge 100 is installed on the corresponding printing device 90, the first recess 204 and the second recess 205 respectively mate with the two protrusions on the printing device, and the two protrusions are inserted into the two recesses of the regenerated ink cartridge 100, making the installation process smoother and preventing jamming during installation.

[0076] Reference Figure 14 As shown, Figure 14 The present invention provides a method for manufacturing a regenerated ink cartridge 100, which is used to manufacture the above-mentioned regenerated ink cartridge and specifically includes the following steps:

[0077] S11. Obtain the original ink cartridge.

[0078] Specifically, the original ink cartridge can be purchased from the market. The original ink cartridge includes an ink cartridge body, which has a first side surface, a second side surface, a bottom surface and a top surface. The first side surface is arranged opposite to the second side surface, the top surface is arranged opposite to the bottom surface, and the bottom surface has an ink outlet.

[0079] S12: remove the chip from the original ink cartridge and process the chip.

[0080] The processing of the chip removed from the original ink cartridge includes rewriting the chip or replacing the wafer.

[0081] S13, processing the second side surface of the original ink cartridge.

[0082] Specifically, processing the second side surface includes cutting off a protrusion on the second side surface, or drilling a hole on the second side surface for matching with the connecting piece.

[0083] S14, connecting the external body to the original ink cartridge to obtain a regenerated ink cartridge.

[0084] Specifically, the external body 2 is coupled to the original ink cartridge and fixed or sealed so that the main body 21 of the external body 2 is disposed on the second side surface 112 of the ink cartridge body 11 and the connector 22 of the external body 2 is disposed on the bottom surface 115 of the ink cartridge body 11 .

[0085] S15. Clean and refill the regenerated ink cartridge with ink, and seal the ink outlet with a sealing film.

[0086] S16. Install the chip after rewriting or replacing the wafer on the regenerated ink cartridge.

[0087] Specifically, as needed, a chip rack can be installed on the regenerated ink cartridge first, and then the chip after rewriting or replacing the wafer can be installed on the chip rack.

[0088] S17. Label and package the recycled ink cartridges.

[0089] Continue to refer to Figure 5 As shown, a printing device 90 includes an ink supply needle 91, with first and second protrusions 92, 93, and a bottom surface 92a of the ink supply needle on either side of the ink supply needle 91. A remanufactured ink cartridge 100 is mounted on the corresponding printing device 90 along the Z-axis. When the remanufactured ink cartridge 100 is mounted on the corresponding printing device 90, the ink outlet 117 engages with the ink supply needle 91 of the corresponding printing device 90, and the engaging portion 121 engages with the printing device 90. Specifically, the engaging surface 121a of the engaging portion 121 abuts against the engaged surface 91a of the corresponding printing device 90, preventing the remanufactured ink cartridge 100 from being separated from the printing device. The chip 3 engages with the contact pins of the corresponding printing device 90 to form an electrical connection.

[0090] Based on the above embodiments, this application also discloses another specific implementation method. Figure 5As shown, in this embodiment, the remanufactured ink cartridge 100 further includes a sealing component 5 (sealing rubber ring, silicone plug), which is disposed within the ink outlet 117. Furthermore, the sealing component 5 includes a sealing surface 51 that mates with the ink supply needle 91 on the printing device; the sealing surface 51 is flush with the bottom end surface 117a of the ink flow path of the ink outlet 117.

[0091] When the regenerated ink cartridge 100 is installed on the corresponding printing device 90, there will be a certain distance between the bottom end surface 117a of the ink outlet 117 and the bottom surface 92a of the ink supply needle of the printing device 90. It is possible that the sealing component in the ink outlet 117 cannot seal the ink supply needle 91 well, causing the ink to flow out along the outer wall of the ink supply needle 91, resulting in ink leakage.

[0092] In this application, the sealing component 5 is provided so that, before the regenerated ink cartridge 100 is installed in the printing device, the sealing surface 51 is a closed surface or a sealing surface with a sealed cutout. Once the regenerated ink cartridge 100 is installed in the printing device, the sealing surface 51 can completely wrap around the ink supply needle 91, allowing the sealing component 5 to better seal the ink supply needle 91 and reduce ink leakage. Furthermore, the sealing film 7 can be used to seal the ink outlet 117 to prevent ink leakage.

[0093] In this embodiment, the sealing surface 51 is flush with the bottom end surface 117a of the ink flow path of the ink outlet 117. It may be understood that in other embodiments, referring to Figure 6 As shown, portions of the printing device 90 are depicted using dashed lines. The seal member 5 is not shown in its deformed shape when installed on the printing device 90. The seal member 5 is disposed within the ink outlet 117; the seal member 5 includes a sealing surface 51 that mates with the ink supply needle 91 of the printing device. The sealing surface 51 protrudes from the bottom end surface 117a of the ink flow path of the ink outlet 117. The protrusion of the sealing surface 51 from the ink outlet 117 allows the remanufactured ink cartridge 100 to contact the ink supply needle bottom surface 92a of the ink supply needle 91 through the seal member 5 (the closer to the ink supply needle bottom surface 92a, the larger the size of the ink supply needle 91), further preventing ink leakage.

[0094] Based on the above embodiments, this application also discloses a specific implementation method, referring to Figure 7 As shown, Figure 7 This is a disassembled schematic diagram of a remanufactured ink cartridge according to another embodiment of the present invention. The handle 12 of the original ink cartridge 1 has a snap-fitting portion 121, which is provided with a snap-fitting surface 121a. When the original ink cartridge 1 is mounted on a corresponding printing device, the snap-fitting surface 121a engages with the corresponding printing device, securing the cartridge body 11 to the corresponding printing device.

[0095] The regenerated ink cartridge 100 further includes a snap-fitting member 6, which is connected to the handle 12. The snap-fitting member 6 has a new snap-fitting surface 61. When the regenerated ink cartridge 100 is mounted on the corresponding printing device 90, the new snap-fitting surface 61 abuts against the engaging surface 91a of the corresponding printing device 90, preventing the regenerated ink cartridge 100 from being separated from the printing device. The snap-fitting member 6 is positioned on the handle 12 as shown in FIG. Figure 9 shown.

[0096] In this embodiment, referring to Figure 8 As shown, the clamping component 6 includes a clamping body 62 and a coupling portion 63. A new clamping surface 61 is provided on the clamping body 62 for contacting with the coupled surface 91a of the corresponding printing device 90. The coupling portion 63 is connected to the clamping body 62 and is used to fix the clamping component 6 to the handle 12. Furthermore, the coupling portion 63 can be a protrusion connected to the clamping body 62. A protrusion is provided on the clamping component 6, and a hole is provided on the ink cartridge body 11. The protrusion is inserted into the hole to position the clamping component 6 on the ink cartridge body 11. Preferably, referring to Figure 7 As shown, a snap-fit ​​hole 120 is opened on the surface of the +Y axis side of the handle 12, and the engaging portion 63 (protrusion) on the snap-fit ​​component 6 is inserted into the snap-fit ​​hole 120 to position the snap-fit ​​component 6 on the ink cartridge body 11. Specifically, the snap-fit ​​component 6 is positioned on the handle 12 of the original ink cartridge 1.

[0097] It is understood that in other embodiments, the clamping member 6 may also be attached to the handle 12 of the original ink cartridge 1 by adhesion, which can also achieve the beneficial effects of this embodiment. Specifically, the clamping member 6 is adhered to the -Z axis side of the engagement portion 121 of the handle 12 of the original ink cartridge 1.

[0098] The embodiment of the present application further discloses a method for manufacturing a regenerated ink cartridge 100. The method is used to manufacture the above-mentioned regenerated ink cartridge, and specifically comprises the following steps:

[0099] S101. Obtain an original ink cartridge.

[0100] Specifically, the original ink cartridge can be purchased from the market. The original ink cartridge includes an ink cartridge body, which has a first side surface, a second side surface, a bottom surface and a top surface. The first side surface is arranged opposite to the second side surface, the top surface is arranged opposite to the bottom surface, and the bottom surface has an ink outlet.

[0101] S102: Remove the chip from the original ink cartridge and process the chip.

[0102] The processing of the chip removed from the original ink cartridge includes rewriting the chip or replacing the wafer.

[0103] S103: Process the second side surface of the original ink cartridge.

[0104] Specifically, processing the second side surface includes cutting off a protrusion on the second side surface, or drilling a hole on the second side surface for matching with the connecting piece.

[0105] S104: Connect the external body to the original ink cartridge to obtain a regenerated ink cartridge.

[0106] Specifically, the external body 2 is coupled to the original ink cartridge and fixed or sealed so that the main body 21 of the external body 2 is disposed on the second side surface 112 of the ink cartridge body 11 and the connector 22 of the external body 2 is disposed on the bottom surface 115 of the ink cartridge body 11 .

[0107] S105 , cleaning and refilling the regenerated ink cartridge with ink, and sealing the ink outlet with a sealing film.

[0108] S106: Add a clamping component to the handle of the regenerated ink cartridge.

[0109] The engaging component 6 has a new engaging surface 61 . When the regenerated ink cartridge 100 is installed on the corresponding printing device 90 , the new engaging surface 61 engages with the printing device 90 .

[0110] S107. Install the chip after rewriting or replacing the wafer on the regenerated ink cartridge.

[0111] Specifically, as needed, a chip rack can be installed on the regenerated ink cartridge first, and then the chip after rewriting or replacing the wafer can be installed on the chip rack.

[0112] S108. Label and package the recycled black box.

[0113] The arrangement of the external body 2 can regenerate a small-capacity ink cartridge into a large-capacity ink cartridge, thereby solving the problem that empty shells of large-capacity ink cartridges cannot meet the market demand for the large-capacity regenerated ink cartridges.

[0114] The provision of the snap-fit ​​component 6 on the handle 12 can solve the technical problem caused by the inconsistent spacing between the handle snap-fit ​​position and the chip between the regenerated ink cartridge 100 and the original ink cartridge 1 . It is also easy to operate, has a simple production process, and is easy to operate and low in cost.

[0115] Based on the above embodiments, this application also discloses a specific implementation method, referring to Figure 10 、 Figure 11 As shown, Figure 10 This is a partial schematic diagram of a regenerated ink cartridge provided in another embodiment of the present invention. Figure 11FIG2 is a schematic diagram of a clamping component in one embodiment. This embodiment differs from the previous embodiment in that a cutting plane 122 and a positioning hole 123 are provided on the +X-axis surface of the handle 12. The clamping component 6 includes a coupling portion 64, a main body 65, and a connecting portion 66. The main body 65 is provided with a new engaging surface 651, which is used to abut against the engaged surface 91a of the corresponding printing device 90 to prevent the regenerated ink cartridge 100 from being separated from the corresponding printing device 90. The coupling portion 64 is used to secure the clamping component 6 to the handle 12, and the connecting portion 66 connects the coupling portion 64 and the main body 65. The coupling portion 64 can be a protrusion provided on the connecting portion 66 or the main body 65. The clamping component 6 is provided with a protrusion, and the ink cartridge body 11 is provided with a positioning hole 123. The protrusion is inserted into the positioning hole 123 to position the clamping component 6 on the ink cartridge body 11. Specifically, the clamping component 6 is positioned on the handle 12 of the original ink cartridge 1.

[0116] In addition, the cutting plane 122 and the positioning hole 123 can also be set on the -X axis surface of the handle 12.

[0117] The arrangement of the external body 2 can regenerate a small-capacity ink cartridge into a large-capacity ink cartridge, thereby solving the problem that large-capacity empty cartridges cannot meet the market demand for the large-capacity regenerated ink cartridges.

[0118] The provision of the snap-fit ​​component 6 on the handle 12 can solve the technical problem caused by the inconsistent spacing between the handle snap-fit ​​position and the chip between the regenerated ink cartridge 100 and the original ink cartridge 1 . It is also easy to operate, has a simple production process, and is easy to operate and low in cost.

[0119] Based on the above embodiments, this application also discloses a specific implementation method, referring to Figure 13 As shown, Figure 13 A cross-sectional view of an ink cartridge provided in accordance with an embodiment of the present application. The regenerated ink cartridge 100 further includes an elastic sealing component 8, which may be a component having the same or different structure from the sealing component 5. Specifically, the elastic sealing component 8 is disposed within the ink outlet 117. The elastic sealing component 8 includes a sealing surface 81 that matches the ink supply needle 91 on the printing device 90; the sealing surface 81 is flush with the bottom end surface 117a of the ink flow path of the ink outlet 117. Before the regenerated ink cartridge 100 is installed on the printing device, the sealing surface 81 is a closed surface or a sealing surface with a sealed incision. After the regenerated ink cartridge 100 is installed on the printing device 90, the sealing surface 81 can completely wrap around the ink supply needle 91, allowing the elastic sealing component 8 to better seal the ink supply needle 91, thereby reducing ink leakage. In addition, the ink outlet 117 can be sealed with a sealing membrane 7 to prevent ink leakage.

[0120] After adopting this solution, the regenerated ink cartridge 100 is fixed to the printing device 90 using the elastic sealing component 8, and the handle 12 is not needed. Therefore, the handle 12 can be eliminated (for example, the handle 12 is cut off), or the locking position 121 on the handle 12 will not be locked to the printing device 90.

[0121] This technical solution can solve the technical problem caused by the inconsistent spacing between the handle engagement position and the chip between the regenerated ink cartridge 100 and the original ink cartridge 1, and is not affected by the handle 12, thereby improving production efficiency.

[0122] It will be appreciated that, in other embodiments, the sealing surface 81 of the elastic sealing member 8 protrudes from the bottom end surface 117a of the ink flow path of the ink outlet 117. The protrusion of the sealing surface 81 from the ink outlet 117 allows the remanufactured ink cartridge 100 to contact the ink supply needle bottom surface 92a of the ink supply needle 91 through the elastic sealing member 8 (the closer to the ink supply needle bottom surface 92a, the larger the size of the ink supply needle 91), further preventing ink leakage.

[0123] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
