Abstract

This invention provides a print cartridge used in ink-jet printer. With the pressure cast by an air pressure pump, the print cartridge provides the printing ink for the printing head; inside the said print cartridge installs a printing ink bag, which packs ink inside and is formed by flexible material; between the outer part of the print cartridge and the said printing ink bag mounts a pressure room in which the pressure is produced by the air pressure pump; on the outer part of the print cartridge sets up a pressure air inlet which introduces pressure air produced by the air pressure pump; on the said printing ink bag installs an ink leading-out terminal which can lead out the ink from the printing ink bag; when the print cartridge is dismantled from the printer, the said pressure air inlet opens, so as to interconnect the said pressure room with the atmosphere, and the ink leading out terminal is closed. This invention is characterized in that the print cartridge can easily be assembled and dismantled, and the print cartridge and the constitute parts thereof can be easily reused, and thus saves resources.
