[0051] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0052] Ink cartridges are consumables in printers that need to be replaced frequently. Some different types of ink cartridges have the same structure but different capacities. Currently, the number of large-capacity empty ink cartridge shells available for recycling is far less than the number of small-capacity empty ink cartridge shells. Therefore, relevant companies need to recycle and modify small-capacity ink cartridges into large-capacity recycled ink cartridges suitable for specific printers.

[0053] Usually, when remanufacturing an ink cartridge, it is necessary to break open the specific chamber inside the original small-capacity ink cartridge to remanufacture it into a regenerated ink cartridge. The remanufactured regenerated ink cartridge needs to correspond to the positioning components on the printer, which specifically involves partial cutting of two walls on the original ink cartridge. In addition, the recycling of this type of ink cartridge also involves the disassembly and reinstallation of the original chip, which involves cutting and gluing processes. The above two types of processing are difficult and prone to defects such as breakage, burrs, and glue overflow, which affect the quality and appearance of the regenerated ink cartridge. In addition, there are many processes involved, which is not conducive to improving production efficiency.

[0054] The regenerated ink cartridge provided in the embodiment of the utility model can be detachably installed in a printer, and the printer can be an inkjet printer. The regenerated ink cartridge is used to store ink and supply ink for the printing work of the printer.

[0055] refer to Figure 1 As shown, the printer includes a mounting portion 2, and the mounting portion 2 is used to carry multiple or one ink cartridge. The mounting portion 2 has an opening 21, and the ink cartridge is detachably mounted in the mounting portion 2 along the mounting direction, i.e., the -Z axis direction. For example, the opening 21 of the mounting portion can be located at the top of the mounting portion 2, and the ink cartridge is loaded into the mounting portion 2 from the opening 21 along the vertical downward mounting direction.

[0056] The mounting part 2 of the printer is provided with an ink supply part 22, which can be located on the inner bottom wall of the mounting part 2. When the ink cartridge is installed on the mounting part 2 of the printer, the ink in the ink cartridge reaches the ink supply part 22 of the mounting part 2 through the ink outlet 111, and the ink supply part 22 supplies the ink to the print head. The print head sprays the ink onto the printing medium to form text or patterns, thereby performing a printing action, wherein the printing medium can be, for example, paper.

[0057] In order to facilitate the introduction of a regenerated ink cartridge provided by the present utility model, reference is made to Figure 2 As shown, a coordinate system is established. In this example, the first direction is the height direction of the regenerated ink cartridge, and the first direction is referenced Figure 2 The second direction is the width direction of the regenerated ink cartridge, and the second direction is the reference direction. Figure 2 The X-axis indicates the direction; the third direction is the length direction of the regenerated ink cartridge, and the third direction is referenced Figure 2 The direction indicated by the Y axis in . The angles between the first direction, the second direction and the third direction may be 90°. Figure 1 and Figure 2 As shown, the installation direction of the regenerated ink cartridge 1 is -Z and Figure 2 The Z axis in the figure indicates the opposite direction.

[0058] In other possible implementations, the angles between the first direction, the second direction, and the third direction may also be 80° to 100°, for example, 80°, 85°, 90°, 95°, or 100°.

[0059] refer to Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a regenerated ink cartridge, comprising: an original ink cartridge 100 and a replacement part 500, the original ink cartridge 100 comprises a shell 110, one end of the shell 110 along the first direction is a bottom wall 1106, one end along the second direction is a front wall 1101, one end along the third direction is a left side wall 1103, the other end of the shell 110 along the third direction is open, the shell 110 has a notch 117 penetrating the bottom wall 1106, the front wall 1101 and the left side wall 1103, the shell 110 has a first chamber 115 and a second chamber 116, the first chamber 115 is used to store ink, and the second chamber 116 is connected to the notch 117;

[0060] The replacement part 500 is arranged on the original ink cartridge 100, and the replacement part 500 includes an external part 510 and an internal part 520 that are connected to each other. The external part 510 is arranged at the position of the notch 117, and the internal part 520 is arranged in the second chamber 116. The external part 510 has a recessed part 512, and the recessed part 512 is configured to position the regenerated ink cartridge when the regenerated ink cartridge is installed to the installation part 2 of the printer.

[0061] The first direction is the installation direction of the regenerated ink cartridge, and the second direction and the third direction both have an angle with the first direction.

[0062] The utility model provides a regenerated ink cartridge, referring to Figure 1 and Figure 2 As shown, the original ink cartridge 100 is obtained by removing part of the structure of the recycled small-capacity ink cartridge 3, and then the replacement part 500 is connected to the original ink cartridge 100. The recessed portion 512 of the replacement part 500 can meet the positioning requirements of the regenerated ink cartridge, eliminating the need to perform a cutting process for the positioning groove on the small-capacity ink cartridge 3, which helps to improve product quality and production efficiency. In addition, in the present application, by replacing part of the structure of the small-capacity ink cartridge 3 with the replacement part 500, it is also convenient to reinstall the chip to the replacement part 500, so as to ensure that the function of the regenerated ink cartridge is not lost due to the removal of part of the structure of the small-capacity ink cartridge 3.

[0063] For ease of explanation, refer to Figure 2 , Figure 3 and Figure 4 As shown, the present embodiment defines a front wall 1101, a rear wall 1102, a left side wall 1103, a top wall 1105 and a 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 arranged relatively in the length direction of the shell 110, that is, Figure 4 The left side wall 1103 of the housing 110 and the opening are relatively arranged in the thickness direction of the housing 110. Figure 2The top wall 1105 and the bottom wall 1106 of the housing 110 are relatively arranged in the height direction of the housing 110. Figure 2 The upper and lower ends of the Z direction shown in .

[0064] refer to Figure 3 and Figure 4 As shown, the ink outlet 111 may be disposed on the bottom wall 1106 of the housing 110 .

[0065] refer to Figure 2 , Figure 3 and Figure 4 As shown, the first chamber 115 is used to store ink and is the main chamber of the original ink cartridge 100. The ink outlet 111 is connected to the first chamber 115. The ink outlet 111 and the first chamber 115 can be correspondingly arranged so that the ink in the first chamber 115 can easily flow out from the ink outlet 111.

[0066] The second chamber 116 is a specific chamber of the original ink cartridge 100, which mainly plays a buffering role and can maintain the internal air pressure balance of the original ink cartridge 100. The second chamber 116 is not used to store ink, so the volume of the second chamber 116 is not included in the ink storage capacity of the ink cartridge.

[0067] refer to Figure 1 and Figure 2 As shown, the regenerated ink cartridge 1 is obtained by remanufacturing and processing on the basis of the original small-capacity ink cartridge 3.

[0068] In one possible implementation, reference Figure 1 and Figure 2 As shown, the recessed portion 512 is recessed toward the inside of the external portion 510 at the bottom end of the external portion 510 along the first direction.

[0069] In this example, the recessed portion 512 is a groove. When the regenerated ink cartridge 1 is installed on the mounting portion 2 of the printer, the recessed portion 512 is used as a positioning groove. The limiting protrusion in the mounting portion 2 (not shown in the figure) is inserted into the recessed portion 512 to achieve the effect of positioning the regenerated ink cartridge 1.

[0070] In a possible implementation, the cross-sectional shape of the recessed portion 512 may be circular, elliptical, rectangular, or the like.

[0071] Considering that the limiting protrusion in the mounting portion 2 extends along the first direction, that is, along the direction indicated by the Z axis, therefore, in the present application, the opening of the recessed portion 512 is located at the bottom end of the external portion 510, so as to facilitate the insertion of the limiting protrusion in the mounting portion 2 into the recessed portion 512.

[0072] In one possible implementation, reference Figure 1 and Figure 2As shown, a regenerated ink cartridge provided by an embodiment of the utility model further includes an electrical connection portion 400 , and a side of the external portion 510 facing away from the internal portion 520 has a mounting position 513 , and the electrical connection portion 400 is disposed at the mounting position 513 .

[0073] The electrical connection part 400 includes but is not limited to a chip. The mounting part 2 of the printer is also provided with an electrical contact part 24. The electrical contact part 24 may include a stylus holder 241 and a stylus 242. One side surface of the stylus holder 241 may be mounted on the inner wall surface of the mounting part 2, and the stylus 242 is arranged on the other side surface of the stylus holder 241. The electrical connection part 400 is communicatively connected with the electrical contact part 24 of the mounting part 2 to realize signal transmission.

[0074] The electrical connection portion 400 can be used to store information such as manufacturer information, ink volume information, consumable box category information, ink color information, related processing procedures and communication procedures, etc.

[0075] The electrical connection part 400 can be set at the installation position 513 of the external part 510 by bonding, welding, screws, snap-on connection, etc., so that the electrical connection part 400 is first set at the installation position 513 of the external part 510, and then the replacement part 500 is installed in the original ink cartridge 100, thereby realizing the installation of the electrical connection part 400, eliminating the tedious process of disassembling and reinstalling the original chip, which helps to improve the accuracy of the installation position of the electrical connection part 400.

[0076] In one possible implementation, reference Figure 1 and Figure 2 As shown, the mounting position 513 is located on a side of the external part 510 facing the electrical contact part 24 of the mounting part 2. In this example, the mounting position 513 is located on the third direction side of the external part 510, that is, the outer wall surface in the Y-axis direction. The mounting position 513 on the external part 510 for mounting the electrical connection part 400 corresponds to the position in the printer for receiving the electrical connection part 400, so that the electrical connection part 400 and the electrical contact part 24 of the mounting part 2 can be easily connected to each other in communication.

[0077] The utility model arranges the electrical connection part 400 at the installation position 513 of the external part 510, thereby eliminating the need for disassembly and reinstallation of the electrical connection part 400 when modifying the recycled ink cartridge. The position of the electrical connection part 400 can be changed by directly replacing the replacement part 500 on which the electrical connection part 400 is installed, thereby preventing defects such as glue overflow caused by disassembly and reinstallation of the electrical connection part 400, thereby ensuring the quality and appearance of the recycled ink cartridge and reducing the modification process, which is conducive to improving production efficiency.

[0078] In one possible implementation, the shell 110 of the original ink cartridge 100 may include a main shell 113 and a cover body 114. A welding film (not shown in the figure) is provided on the open side of the shell 110, and the welding film serves to seal the hollow cavity in the shell 110. The cover body 114 can be provided on the open side of the shell 110, and the cover body 114 covers the outside of the welding film, and the cover body 114 serves to protect the welding film.

[0079] In one possible implementation, reference Figure 2 , Figure 3 and Figure 4 As shown, the hollow cavity in the housing 110 includes a first chamber 115 and a second chamber 116 , and the housing 110 has a connecting portion 118 connecting the first chamber 115 and the second chamber 116 .

[0080] The first chamber 115 and the second chamber 116 in the housing 110 can be arranged side by side along the length direction of the housing 110, that is, arranged side by side along the Y-axis direction, the first chamber 115 can be arranged close to the rear wall 1102 of the housing 110, and the second chamber 116 can be arranged close to the front wall 1101 of the housing 110. Such a structure allows the communication hole 112 opened on the rear wall 1102 of the housing 110 to communicate with the first chamber 115 in the housing 110.

[0081] refer to Figure 3 and Figure 4 As shown, the communication portion 118 may be located on the outer wall surface of the left side wall 1103 of the housing 110, or the communication portion 118 is located on the outer wall surface of the main housing 113 on the side away from the cover body 114. The two ends of the communication portion 118 extend to the corresponding areas where the first chamber 115 and the second chamber 116 are located, and one end of the communication portion 118 forms a channel opening 1182 communicating with the first chamber 115, and the other end of the communication portion 118 forms an open end 1181, and the first chamber 115 and the second chamber 116 are connected through the communication portion 118.

[0082] Since the connecting portion 118 is disposed on the outer wall surface of the housing 110, the connecting portion 118 may be a groove sunken into the housing 110. In order to prevent ink from overflowing from the connecting portion 118, refer to Figure 2 , Figure 3 and Figure 7 As shown, the left side wall 1103 of the shell 110 may also be covered with a sealing layer 150, which may be a welding film. The sealing layer 150 covers the connecting portion 118, and the sealing layer 150 and the connecting portion 118 together form a sealed channel to prevent ink from overflowing.

[0083] In a possible implementation, the regenerated ink cartridge further includes a blocking structure, which is used to block the flow of fluid between the first chamber 115 and the second chamber 116 through the connecting portion 118 .

[0084] In one possible implementation, reference Figure 3 and Figure 4 As shown, the communication portion 118 forms a channel opening 1182 communicating with the first chamber 115, and the blocking structure includes an intercepting member 161 disposed in the channel opening 1182. The channel opening 1182 may be a circular hole, and the intercepting member 161 may be cylindrical. The channel opening 1182 is blocked by the intercepting member 161, so as to block the flow of ink between the first chamber 115 and the second chamber 116.

[0085] In one possible implementation, the channel opening 1182 is a through hole that passes through the left side wall 1103, one end of the channel opening 1182 is connected to the first chamber 115, and the other end is connected to the connecting portion 118, and the intercepting member 161 is an intercepting column arranged in the through hole, and the intercepting column can be an interference fit with the channel opening 1182 to achieve a blocking effect on the connecting portion 118, thereby preventing ink from flowing between the first chamber 115 and the second chamber 116 through the connecting portion 118.

[0086] In one possible implementation, reference Figure 3 , Figure 7 and Figure 8 As shown, the connecting portion 118 also has an open end 1181 extending to the position of the notch 117, and the blocking structure includes a blocking protrusion 162. Along the third direction, the blocking protrusion 162 is arranged on one side of the external portion 510; and the blocking protrusion 162 blocks the position of the opening end 1181 facing the external portion 510.

[0087] In this example, since the left side wall 1103 is located on the -X axis side of the shell 110 , the blocking protrusion 162 is arranged on the -X axis side of the external part 510 , so that the blocking protrusion 162 blocks the position of the opening end 1181 facing the external part 510 .

[0088] In one possible implementation, the blocking protrusion 162 may be a blocking block or a blocking plate. The blocking protrusion 162 may be fixedly connected to the connection position between at least part of the external portion 510 and the opening end 1181 by welding, gluing, etc. The blocking protrusion 162 and the end surface of the opening end 1181 fit together, thereby blocking and sealing the opening end 1181, thereby preventing ink from flowing between the first chamber 115 and the second chamber 116 through the connecting portion 118.

[0089] In one possible implementation, the blocking protrusion 162 and the replacement part 500 are an integral structure connected in one piece. With such a structure, there is no need to install the blocking protrusion 162 again. The blocking protrusion 162 mainly serves to block the opening end 1181 to prevent ink from flowing through the opening end 1181.

[0090] In order to ensure the sealing of the connection position between the opening end 1181 and the external part 510, the regenerated ink cartridge provided in the embodiment of the utility model is further provided with a film layer 300 covering the connection position between the blocking protrusion 162 and the opening end 1181 on one side in the third direction. The film layer 300 can be a welding film. The film layer 300 is welded to one side of a part of the blocking protrusion 162 along the third direction and one side of a part of the shell 110 along the third direction. The film layer 300 covers the opening end 1181 to improve the sealing effect.

[0091] In other possible implementations, the blocking structure may include a sealing member (not shown in the figure) instead of the blocking protrusion 162. The sealing member may be disposed on the end surface of the opening end 1181 facing the replacement member 500, so that the sealing member is located between the end surface of the opening end 1181 and the replacement member 500, and the sealing member seals the end surface of the opening end 1181. In this example, the sealing layer includes but is not limited to a welding film, a sticker or a plug.

[0101] In one possible implementation, reference Figure 5 and Figure 6 As shown, the second chamber 116 has a first sub-chamber 1161 and a second sub-chamber 1162 inside, and the second chamber 116 also has a first partition wall 120 and a second partition wall 130 inside, the first partition wall 120 separates the first sub-chamber 1161 from the second sub-chamber 1162, and the second partition wall 130 separates the first sub-chamber 1161 from the first chamber 115;

[0102] The inner portion 520 is located in the first sub-chamber 1161 and abuts against at least one of the first partition wall 120 and the second partition wall 130 .

[0103] In a possible implementation, the first sub-chamber 1161 may be a rectangular chamber, the length direction of the first partition wall 120 is along the third direction, that is, the direction indicated by the Y axis, one end of the first partition wall 120 intersects with one end of the second partition wall 130, and the other end of the first partition wall 120 is connected to the front wall 1101 of the housing 110. The length direction of the second partition wall 130 is along the first direction, that is, the direction indicated by the Z axis, and one end of the second partition wall 130 intersects with one end of the first partition wall 120, and the other end of the second partition wall 130 is connected to the bottom wall 1106 of the housing 110.

[0104] The built-in portion 520 is located in the first sub-chamber 1161 , and the side wall of the built-in portion 520 may abut against the first partition wall 120 , or the second partition wall 130 , or both side walls of the built-in portion 520 may abut against the first partition wall 120 and the second partition wall 130 , respectively.

[0105] refer to Figure 2 and Figure 3 As shown, the housing 110 of the original ink cartridge 100 further has a pressure relief valve chamber 170, which may be a chamber recessed from the left side wall 1103 of the housing 110 to the inside of the housing 110, the side wall of the pressure relief valve chamber 170 is located inside the housing 110, the side wall of the pressure relief valve chamber 170 may be in an arc shape, and the side wall of the pressure relief valve chamber 170 may be partially located in the first sub-chamber 1161, partially located in the second sub-chamber 1162, and partially located in the first chamber 115. Figure 5 and Fig. 9 As shown, the built-in part 520 also has an arc portion 530, which abuts against a portion of the side wall of the pressure reducing valve chamber 170 located in the first sub-chamber 1161, and can increase the contact area between the built-in part 520 and the shell 110, thereby improving the welding or bonding firmness of the replacement part 500 and improving the stability of the assembly of the replacement part 500 and the shell 110.

[0106] refer to Figure 6 and Figure 7 As shown, the regenerated ink cartridge 1 also includes an external body 200, which is connected to the original ink cartridge 100. By setting the external body 200, the external dimensions of the regenerated ink cartridge 1 are the same as the external dimensions of the large-capacity ink cartridge, so that the regenerated ink cartridge 1 is compatible with a printer equipped with a large-capacity ink cartridge.

[0107] In this embodiment, the remanufactured regenerated ink cartridge 1 is at least the same in external dimensions as the corresponding large-capacity ink cartridge. Thus, the remanufactured ink cartridge 1 can be used in a printer equipped with a large-capacity ink cartridge. As for the ink filling amount of the remanufactured regenerated ink cartridge 1, it can be the same as or slightly more than the corresponding large-capacity ink cartridge.

[0108] Among them, according to the actual needs of the user, the external body 200 can be designed as a hollow structure, and the external body 200 can have a accommodating cavity (not shown in the figure), which is used to accommodate ink, so as to achieve the effect of expanding the capacity of the original ink cartridge 100, so that the amount of ink that can be held in the regenerated ink cartridge 1 is greater than the amount of ink that can be held in the original ink cartridge 100, that is, the volume of ink that can be held in the regenerated ink cartridge 1 is larger.

[0109] Of course, in other possible implementations, the external body 200 does not have a containing cavity inside, or the containing cavity inside the external body 200 is not used to contain ink.

[0110] refer to Figure 6 and Figure 7 As shown, the original ink cartridge 100 may be in a relatively regular rectangular shape, and the regenerated ink cartridge 1 provided in the embodiment of the present application may also be in a relatively regular rectangular shape, so that the regenerated ink cartridge 1 matches the shape and size of the corresponding large-capacity ink cartridge.

[0111] refer to Figure 1 and Figure 2 As shown, the original ink cartridge 100 includes a housing 110, and the housing 110 has a hollow cavity inside, and the hollow cavity in the housing 110 can accommodate ink. An ink outlet 111 is arranged on the outer wall of the housing 110, and the ink outlet 111 is connected to the hollow cavity in the housing 110 for accommodating ink. When the regenerated ink cartridge 1 is installed in the printer, the ink outlet 111 of the original ink cartridge 100 is docked with the ink supply part 22 in the printer, so that the ink in the original ink cartridge 100 is supplied from the ink outlet 111 to the ink supply part 22.

[0112] The regenerated ink cartridge 1 is usually installed in the printer in a vertical direction, and the ink outlet 111 of the original ink cartridge 100 can be set on the bottom wall 1106 of the housing 110. Under the gravity of the ink and the negative pressure on the printer side, the ink in the original ink cartridge 100 can smoothly flow out from the ink outlet 111 on the bottom wall 1106 of the housing 110 to supply ink to the printer.

[0113] refer to Figure 3 and Figure 6As shown, the external body 200 can be located at the rear side of the original ink cartridge 100, and the external body 200 can be attached to the rear wall 1102 of the original ink cartridge 100. Compared with the original ink cartridge 100, under the support of the external body 200, the length and volume of the regenerated ink cartridge 1 are increased, and the thickness still maintains the thickness of the original ink cartridge 100. The regenerated ink cartridge 1 is in a flat box shape as a whole to meet the installation requirements in the printer.

[0114] refer to Figure 4 , Figure 6 and Figure 7 As shown, the external body 200 may include a box body 210, which is the main structure of the external body 200. The box body 210 is located on the side where the first chamber 115 is located, and the accommodating cavity in the box body 210 can be connected 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.

[0115] In this example, the box body 210 is located at the rear side of the original ink cartridge 100, and the box body 210 can be attached to the rear wall 1102 of the original ink cartridge 100. The box body 210 is used to increase the length of the regenerated ink cartridge 1 so that the outer dimensions of the regenerated ink cartridge 1 match the outer dimensions of the corresponding large-capacity ink cartridge.

[0116] The external body 200 may also include a connecting plate 220, which may be connected to the top of the box body 210, and the connecting plate 220 is located on the side of the box body 210 facing the original ink cartridge 100, and the connecting plate 220 extends toward the original ink cartridge 100, and the connecting plate 220 may be attached to the top wall 1105 of the original ink cartridge 100.

[0117] The box body 210 and the connecting plate 220 of the external body 200 can be connected to the original ink cartridge 100 to increase the connection area between the external body 200 and the original ink cartridge 100 and enhance the connection strength between the two. In addition, the box body 210 and the connecting plate 220 can position the external body 200 from different directions, which can ensure the docking accuracy of the external body 200 and the original ink cartridge 100. Furthermore, under the joint action of the box body 210 and the connecting plate 220, the connection between the external body 200 and the original ink cartridge 100 can be ensured to be stable and reliable, thereby improving the reliability of the regenerated ink cartridge 1.

[0118] Exemplarily, 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 by 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 by ultrasonic welding.

[0119] refer to Figure 2 , Figure 6 and Figure 7 As shown, in order to allow 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 with the hollow cavity for accommodating ink in the original ink cartridge 100. At this time, one of the external body 200 and the original ink cartridge 100 may be provided with a hollow connecting column 211, and the other may be provided with a connecting hole 112. After the external body 200 and the original ink cartridge 100 are assembled together, the connecting column 211 passes through the connecting hole 112 to achieve the connection between the external body 200 and the original ink cartridge 100.

[0120] When the small-capacity ink cartridge 3 is converted into the original ink cartridge 100, a connecting hole 112 can be provided on the small-capacity ink cartridge 3. In other words, the connecting hole 112 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 112 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 on the outer wall of the external body 200, and the connecting column 211 is connected to the accommodating cavity in the external body 200.

[0121] Of course, a hollow connecting column can also be set on the original ink cartridge 100, and a connecting hole can be set on the external body 200. The connecting column on the original ink cartridge 100 passes through the connecting hole on the external body 200 to achieve the connection between the external body 200 and the original ink cartridge 100. This embodiment does not limit this.

[0122] The following description is made by taking the example that the connecting hole 112 is provided on the original ink cartridge 100 and the hollow connecting column 211 is provided on the external body 200.

[0123] In some embodiments, there may be only one connection portion between the external body 200 and the original ink cartridge 100. In other words, only one connection column 211 is provided on the external body 200, and only one connection hole 112 is provided on the original ink cartridge 100. In this case, the connection portion between the external body 200 and the original ink cartridge 100 serves as a passage portion for ink, so that the ink in the accommodating cavity of the external body 200 can flow into the original ink cartridge 100.

[0124] In addition, the external body 200 may also be provided with an air inlet 215, through which air can enter the accommodating chamber to maintain the air pressure balance in the accommodating chamber and guide the ink into the original ink cartridge 100. Figure 3 As shown, to ensure the internal air pressure balance of the small-capacity ink cartridge. In this regard, 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.

[0125] In some possible implementations, reference Figure 2 , Figure 6 and Figure 7 As shown, there may also be two connecting parts between the external body 200 and the original ink cartridge 100. In other words, two connecting posts 211 are provided on the external body 200, and two connecting holes 112 are provided on the original ink cartridge 100, and the two connecting posts 211 respectively pass through the two connecting holes 112. In this case, one connecting part between the external body 200 and the original ink cartridge 100 serves as a passing part for ink, and the other connecting part between the external body 200 and the original ink cartridge 100 serves as a circulating part for air.

[0126] The connecting portion, which is the ink passage portion, may be located at the bottom of the accommodating cavity of the external body 200, so that the ink in the accommodating cavity of the external body 200 can flow smoothly and completely into the original ink cartridge 100. The connecting portion, which is the air circulation portion, may be close to the top of the accommodating cavity of the external body 200. Air can flow into the accommodating cavity of the external body 200 through the air inlet hole 119 on the original ink cartridge 100 and the connecting portion, so as to ensure the internal air pressure balance of the regenerated ink cartridge 1.

[0127] In addition, a sealing member 140 may be disposed in the communication hole 112 on the original ink cartridge 100 . The sealing member 140 may be a flexible member such as a silicone member or a rubber member.

[0128] Similar to the shell 110 of the original ink cartridge 100, the box body 210 of the external body 200 may include a main box 212 and a cover plate 213, and the main box 212 and the cover plate 213 together form a receiving cavity to facilitate the processing and manufacturing of the box body 210. Among them, 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.

[0129] refer to Figure 1 and Figure 2 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, part of the structure of the small-capacity ink cartridge 3 is cut off and converted into the original ink cartridge 100, and then the replacement part 500 and the original ink cartridge 100 are installed and connected, and the recessed portion 512 of the replacement part 500 forms a positioning structure.
