ABSTRACT:
A device for preventing from ink interruption in a printing head of an ink cartridge in a printer; the prime feature thereof is to suck out air in a second chamber of a printing head after the ink of an ink cartridge of a jet printer is used up, and the prime chamber of the ink cartridge will be refilled with ink; a suck assembly has a hermetic assembly to be in close contact with an outer flat surface of the printing head of the ink cartridge; then, a compression unit can provide a vacuum-pumping effect to suck out air in the second chamber completely so as to prevent the spraying unit of the printing head from having ink interruption.
