Ink cartridge of inkjet printer

Abstract

The invention discloses an ink cartridge of an inkjet printer. The ink cartridge comprises a base which is provided with an ink preparing cavity. The upper side of the right end wall of the ink preparing cavity is communicated with a balance cavity arranged outside the base through a first pipeline. The balance cavity is internally provided with a counterweight. An ink injection cavity is arrangedin the left end wall of the ink preparing cavity. An injection port communicated with the outside is connected on the left end of the ink injection cavity. The left end of the injection port is provided with a removable injection plug. The ink preparing cavity and the ink injection cavity are communicated through a second pipeline. The second pipeline stretches into the ink preparing cavity. Thesecond pipeline is provided with a first one-way valve of which the flow direction is from the ink preparing cavity to the ink injection cavity. The second pipeline is communicated with the upper endwall of the ink injection cavity. The lower end wall of the ink injection cavity is internally provided with a stable cavity.

Description

technical field [0001] The invention relates to the technical field of ink cartridge design for an inkjet printer, in particular to an ink cartridge for an inkjet printer.

[0002] A printer is a device that prints pictures or text on paper. According to the technology used, it can be divided into cylindrical, spherical, inkjet, thermal, laser and other printers. Among them, inkjet printers are more commonly used. A kind of printer, this kind of printer uses the nozzle to spray ink onto the paper to complete the printing, and correspondingly, it needs to install an ink cartridge for storing ink in it. The ink cartridge of a conventional inkjet printer is a disposable type, and the ink cartridge in the ink cartridge When the ink is exhausted, the ink cartridge needs to be replaced. According to different brands, the price of the ink cartridge also varies greatly, resulting in higher printing costs for inkjet printers. For cost considerations, some people who use inkjet printers Manually add ink to prolong the service life of the ink cartridge, but due to improper operation, it is easy to cause damage to the nozzle or disconnection of the printing line
