Abstract

An ink cartridge comprises an ink storage chamber. The ink storage chamber comprises a base plate, a first side wall, second side walls, a fixing seat and an insertion pipe, wherein the first side wall and the second side walls are fixed to the base plate, the fixing seat is fixed to the base plate and arranged on the outer side of the first side wall in a raised manner, and the insertion tube isfixed to the fixing seat. The second side walls are connected to the two ends of the first side wall, the base plate, the first side wall and the second side walls jointly define an ink storage cavity. The insertion tube is used for being connected with an ink bottle in an inserted manner. The side wall of the insertion pipe is provided with an ink opening and a ventilation opening. The ink inletis located above the ventilation opening, and the ink inlet is away from the end, far away from the fixing seat, of the insertion pipe for at least a preset distance. The fixing seat is provided withan ink outlet and an air guide opening. The ink inlet communicates with the ink outlet. The ink outlet communicates with the ink storage cavity. The ink guide opening communicates with the ventilationopening and the external atmosphere. The air guide opening is closer to the insertion tube than the ink outlet.

Description

technical field [0001] The present invention relates to an ink cartridge. Background technique [0002] The ink filling device includes an ink bottle and an ink cartridge. Existing ink cartridges generally have an ink filling cannula, and the top of the cannula is provided with an air passage and an ink passage. The ink bottle is inserted upside down on the ink filling cannula of the ink cartridge. It is automatically injected into the ink cartridge. Although this kind of ink filling device can inject ink into the box conveniently, when the ink channel produces an air block, it will stop before the ink filling is completed or the ink filling can not be automatically injected into the ink cartridge when changing the ink bottle. Contents of the invention [0003] In view of this, it is necessary to provide an ink cartridge that avoids air lock. [0004] An ink cartridge comprises an ink storage chamber, the ink storage chamber includes a bottom plate and a first side wall...
