Problems solved by technology
[0002] In a commonly used printer ink cartridge on the market, an ink filter is installed at the ink outlet, and the cavity above the ink outlet is equipped with a porous material to absorb ink. Under the negative pressure of the print head, the ink flows from the porous The absorbent material is released to the ink outlet filter, and printed on the medium through the nozzles of the print head to form text and patterns. In order to make the printing smooth and reduce the amount of residual ink, two porous materials with different densities are usually placed to form a "density step". One piece with a lower density has a weaker ink absorption ability, and the lower one has a higher density and a stronger ink absorption ability. The material cost and assembly cost of the ink cartridge with this structure are relatively high, and the ink outlet filter and the porous material are set separately. The manufacturing process is complicated and the assembly cost is relatively high

The invention provides a printer cartridge processing technology. According to the printer cartridge processing technology, an ink containing cavity and a negative-pressure generation component containing cavity are included; an ink outlet is formed in the bottom of the negative-pressure generation component containing cavity in the direction of gravity. The ink containing cavity communicates with the bottom of the negative-pressure generation component containing cavity. The cross section of the negative-pressure generation component containing cavity gradually decreased from top to bottom. The negative-pressure generation component containing cavity and the ink outlet are filled with integrally-formed porous materials. The density gradient of the materials is formed from top to bottom. The density of the material of the ink outlet is highest, and the ink outlet has the function of an inlet outlet filter tip. The cartridge manufactured through the printer cartridge processing technology is simple in structure, reliable in performance, large in ink capacity, convenient to manufacture and low in cost.
