[0002] Printer cartridges mainly refer to the components in inkjet printers that are used to store printing ink and ultimately complete printing.

[0003] The utility model patent application document with publication number "CN204998141 U" discloses an ink cartridge, which is mainly composed of an ink cartridge body, an ink cartridge cover and a sealing ring. The ink cartridge cover of this technical solution is detachably connected to the ink cartridge body, which is convenient to open and remove impurities, reducing cleaning time, avoiding replacement of new ink cartridges, and avoiding waste of materials.

[0004] The ink cartridge disclosed in the above document has the following defects: the ink cartridge body and the ink cartridge cover are fixed and installed by screws and threaded holes. However, during long-term use, the inner surface of the threaded hole and the outer surface of the screw are worn, which causes the connection between the ink cartridge body and the ink cartridge cover to loosen. At the same time, due to the fixing method of the screw and the threaded hole, the screw cannot be removed without a screwdriver, and the ink cartridge cover cannot be removed from the ink cartridge body.

[0005] It can be seen from this that the existing ink cartridge and ink cartridge cover do not have a good connection structure, and it is necessary to improve the existing deficiencies and provide a printer ink cartridge and a printer. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0026] See also Figure 1 - Figure 4 As shown, the utility model is a printer ink cartridge and a printer, comprising an ink cartridge body 1 and an ink cartridge cover 2, both ends of the ink cartridge body 1 are provided with a first connecting block 101, both ends of the ink cartridge cover 2 are provided with a second connecting block 201, a through opening 102 is opened in the middle of the first connecting block 101, a limit block 202 is provided on the lower surface of the second connecting block 201, the limit block 202 is slidably connected inside the through opening 102, a cavity 203 is opened inside the limit block 202, a fixed block 204 is slidably connected inside the cavity 203, the fixed block 204 is fixed in two and symmetrically arranged, a spring 205 is installed between the two fixed blocks 204, a limit groove is opened on the inner surface of the cavity 203, a protrusion 206 is provided on the outer surface of the fixed block 204, and the protrusion 206 is slidably connected inside the limit groove.

[0027] A plurality of ink outlet holes 103 are formed on the lower surface of the ink cartridge body 1 . An ink outlet tube 3 is installed inside the ink outlet hole 103 . One end of the ink outlet tube 3 extends into the interior of the ink cartridge body 1 .

[0028] A positioning hole 104 and a mounting groove 105 are provided on the upper surface of the ink cartridge body 1 . A sealing plate 4 is installed inside the mounting groove 105 . A filter sponge layer 401 is provided in the middle of the sealing plate 4 .

[0029] A positioning post 207 is provided on the lower surface of the ink cartridge cover 2 , and the positioning post 207 is installed inside the positioning hole 104 .

[0030] A connecting line 5 is installed on the upper surface of the ink cartridge cover 2 .

[0031] A printer includes a printer cartridge.

[0032] When in use, first squeeze the fixing block 204 so that the fixing block 204 moves inside the cavity 203, and at the same time the spring 205 gradually contracts. When the outer surface of the fixing block 204 is flush with the outer surface of the limiting block 202, the ink cartridge cover 2 is pulled upwards at this time, so that the limiting block 202 is separated from the inside of the through opening 102, and the separation of the ink cartridge cover 2 and the ink cartridge body 1 is completed. Then the sealing plate 4 is placed inside the mounting groove 105, and then ink is injected into the filter sponge layer 401. The ink flows into the interior of the ink cartridge body 1 after being filtered by the filter sponge layer 401. The mounting groove 105 and the sealing plate 4 are used in conjunction with the sealing plate 4 to increase the sealing between the ink cartridge body 1 and the ink cartridge cover 2, thereby avoiding ink leakage at the connection between the ink cartridge body 1 and the ink cartridge cover 2. At the same time, the filter sponge layer 401 is provided to filter the ink injected into the ink cartridge body 1, thereby avoiding impurities in the ink clogging the ink outlet tube 3, thereby extending the service life of the ink outlet tube 3, and injecting ink. After the ink is added, the ink cartridge cover 2 is placed on the upper end of the ink cartridge body 1 so that the first connecting block 101 is aligned with the second connecting block 201, and then the ink cartridge cover 2 is pushed downward so that the fixing block 204 is located inside the through opening 102. While pushing the ink cartridge cover 2, the fixing block 204 pushes the spring 205 to contract. When the outer surface of the fixing block 204 is flush with the outer surface of the limiting block 202, the ink cartridge body 1 and the ink cartridge cover 2 are closed. At the same time, the spring 205 recovers its elasticity and pushes the fixing block 204 to move outward so that the fixing block 204 abuts against the outer surface of the first connecting block 101, thereby completing the fixing of the ink cartridge body 1 and the ink cartridge cover 2. The first connecting block 101, the second connecting block 201, the limiting block 202, the fixing block 204 and the spring 205 are used in coordination to replace the fixing method of the screw and the threaded hole. The ink cartridge cover 2 can be removed from the ink cartridge body 1 without the need for external tools, which has good practicality.
