Abstract

An ink cartridge structure improvement (2) includes the followings: an ink cartridge containing ink therein; a pressure adjustment mechanism, which is disposed inside the ink cartridge; or a bag body added inside the ink cartridge. After ejecting ink from the ink cartridge, the pressure inside the ink cartridge is decreased such that the pressure adjustment mechanism is turned on for allowing the external atmosphere pressure to enter via the input hole so as to drive the pressure adjustment mechanism. Alternatively, the mechanism is allowed to generate a stretching state or a compressing state, in which the negative pressure difference inside the ink cartridge is decreased after the air enters therein such that it is convenient for outputting ink. When the ink cartridge is not used in normal time and the pressure inside the storage chamber is not changed, the passive device can not be driven by the external atmosphere pressure. Therefore, the external air can not be supplemented from the other input hole, and no ink leakage phenomenon is encountered.
