The cartridge cover 2, along with the connecting post 30, positioning plate 31, second limiting platform 15, and limiting groove 28, are an integral structure, all made of PP material.

[0039] In use, assemble cartridge 1 and cover 2 with ink inlet 7 facing upwards. Add ink to cartridge 1 through ink inlet 7. After adding ink, seal ink inlet 7 with a rubber stopper. Remove the rubber stopper at air inlet 8, allowing air inlet 8 to connect with the outside atmosphere. Insert cartridge 1 into the printer, insert the printer's air hose into air inlet 4, and insert the printer's ink delivery hose into ink outlet 3. Remove top ball 12 from ink outlet 3. During printing, the printer's air hose pulses pressurized gas into the pressurized cavity. Under the action of pressure spring 10, the sealing membrane resets, and the expanding sealing membrane squeezes the ink in cartridge 1, causing the ink to flow out through ink outlet 3. As the ink flows out, the pressure inside cartridge 1 decreases, and atmospheric air enters cartridge 1 through air inlet 8, air inlet 17, air passage 19, and air outlet 18, increasing the air pressure inside cartridge 1 and promoting smooth ink flow.

[0040] Therefore, the inkjet printer reusable ink cartridge described in this utility model can solve the problem of non-reusable cartridges, and has the advantages of simple structure and convenient ink filling.
