Description

Technical Field

[0001] The utility model relates to the technical field of printers, and more particularly to a printer ink cartridge. Background Art

[0002] The printer ink cartridge mainly refers to the component in an inkjet printer that stores printing ink and finally completes printing. It is mainly divided into a split ink cartridge and an integrated ink cartridge. The integrated ink cartridge integrates the nozzle on the ink cartridge. When a new ink cartridge is replaced after the ink is used up, it also means that a new print head is replaced at the same time. However, in order to save printing costs, for such ink cartridges, after the ink cartridge is used up, users often refill the empty ink cartridge with ink by themselves. Generally speaking, as long as the operation is correct, the refilled ink will not cause much damage to the nozzle.

[0003] Deficiencies of the prior art: After the existing ink cartridges are filled with ink multiple times, some impurities or dust will be brought into the ink cartridge from the ink filling port along with the ink. Long-term accumulation is likely to cause the filter plate to become blocked, which in turn causes poor ink flow and the printing device cannot be used normally. Moreover, after the ink cartridge is used for a long time, the water in the ink will slowly evaporate, which will cause the ink to become too viscous, and then the ink in the ink absorbing sponge is not easy to flow out, affecting the printing quality of the printer. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a printer ink cartridge to solve the problems existing in the above-mentioned background art.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a squeezing device, which is conducive to squeezing the ink-absorbing sponge, so as to ensure that the ink in the ink-absorbing sponge can flow out normally, thereby ensuring the quality of printing. The interior of the squeezing plate is provided with a notch adapted to the stud. By twisting the screw block, the connecting block can drive the stud to rotate, and the rotation in different directions can make the squeezing plate move up and down, thereby squeezing the ink-absorbing sponge. The ink inside the sponge can flow out through squeezing, and the printing quality will not be affected due to the ink being too viscous and difficult to flow out.

[0013] 2. The utility model is provided with a dredging device, which is conducive to dredging the filter plate. The top head is adapted to the filter groove. By pushing the shift block downward, the connecting column can move inside the fixed shell, thereby driving the limit block to move the connecting plate downward, so that the top head can be inserted into the filter groove in the filter plate, and then the impurities in the filter groove can be cleaned to ensure that it will not be blocked. After loosening the shift block, it can return to its original position under the action of the spring to ensure that the ink can be discharged smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
