Abstract

The invention provides an ink cartridge for an ink jet printer. The ink is supplied to a print head by the action of air pressure after the ink cartridge is applied with air pressure generated by an air pressure pump. An ink pack made of flexible material with ink packed in is provided in the ink cartridge. A pressure chamber applied by the air pressure generated by the air pressure pump is provided between the housing of the ink cartridge and the ink pack. A pressured air inlet for guiding in the pressured air generated by the air pressure pump is provided on the housing of the ink cartridge. An ink outlet for guiding the ink out of the ink pack is provided on the ink pack. When the ink cartridge is detached from the printer, the pressured air inlet is opened to communicate the pressure chamber with atmosphere and the ink outlet is closed. The assembly and disassembly of the ink cartridge is convenient, and the ink cartridge and the components are reused easily, so that it is in favor of resource conservation.

Description

[0001] The present invention is a divisional application of the No. 01100560.2 patent application for invention filed on January 15, 2001 with the title of "ink cartridge and inkjet printer using the same". technical field [0002] The present invention relates to an ink cartridge used in an inkjet printer to supply ink to a print head, and an inkjet printer using the ink cartridge. Background technique [0003] Inkjet printers are now widely used for various printing including color printing because they print with less noise and form high-density fine ink droplets. [0004] Inkjet printers generally have an inkjet printing head that is mounted on a carriage and moves in the width direction of the recording paper, and a paper feeding device that moves the recording paper vertically relative to the moving direction of the printing head. Ink drops are ejected to record on recording paper. [0005] If a print head capable of ejecting various ink droplets such as black, yellow...
