[0002] Inkjet printers are common printing devices. Most existing inkjet printers use ink cartridges that are detachably installed in the inkjet printer to provide ink for printing. During the printing process, the ink loaded in the ink cartridge is sprayed onto paper as a printing medium to form desired patterns and texts.

[0003] The publication number CN 220562385 U discloses a printer ink cartridge structure and a printer, the printer ink cartridge structure comprising: an ink cartridge having an ink storage chamber and an ink inlet connected to the ink storage chamber; an ink absorbing member arranged in the ink storage chamber; an ink buffer cavity corresponding to the area below the ink inlet in the ink storage chamber, which can allow the ink flowing in from the ink inlet to enter the ink absorbing member. After the ink buffer cavity is arranged at the ink inlet of the ink cartridge, the ink is more likely to flow into the central area of ​​the ink absorbing member, so that a certain amount of ink can be stored, giving the ink some buffer time to enter the ink absorbing member, which has an improvement effect on the problem of ink flowing directly from the edge of the ink cartridge to the bottom, and avoids the problem of ink leakage at the printing nozzle at the bottom of the ink cartridge.

[0004] However, the ink cartridge has the following shortcomings: when in use, an ink buffer chamber is provided at the ink inlet to facilitate the flow of ink. However, when too much ink is added at one time, the ink will accumulate in the ink buffer chamber, and the contact area with the ink absorber is small, resulting in low absorption efficiency.
