[0002] Printers are an indispensable tool in the office. Modern ink cartridges mainly refer to the components in inkjet printers that are used to store printing ink and ultimately complete printing.
[0003] The shortcomings of the prior art are as follows: after the ink in the ink cartridge is used up, it is necessary to add ink to the ink cartridge. When adding ink to the ink cartridge, ink is injected into the ink cartridge through the injection port on the cover plate, and most of the injection ports on the cover plate are sealed by sticking labels. After repeatedly peeling off the cover plate to add ink, the adhesion is insufficient, which easily leads to ink leakage. In addition, when the ink cartridge needs to be cleaned, the cover plate needs to be disassembled, and after disassembly, it needs to be fixed and bonded with glue, which is very troublesome. For this reason, we propose a printer ink cartridge that is easy to add ink and clean. Utility Model Content
