[0022] like Figure 1-3 Shown, a kind of recovery method of inkjet printer ink box, described ink box 1 comprises: ink storage chamber 2, can hold the ink that supplies to inkjet printer printhead; The ink in 2 is supplied to the print head; the valve mechanism 4 is set in the ink supply port 3 and consists of a valve core, a spring and a sealing ring. When the ink cartridge is not installed on the printer, it will Under the action of the elastic force of the spring, the valve mechanism is in a closed state. When the ink cartridge is installed on the printer, the ink supply needle on the printer cooperates with the ink supply port, and at this time the When the insertion force of the ink needle is greater than the elastic force, the valve mechanism is opened; the air communication channel 5 communicates the ink storage chamber with the external atmosphere, and has a gas-liquid separation membrane 6 and a through hole 7 on it, and the gas-liquid Separation membrane 6 is formed...
