ABSTRACT:
An ink cartridge includes a hollow ink tank body, a cover member connected to the hollow ink tank body, a hollow tube and a pressure regulator arranged inside the hollow ink tank body. The cover member has an air vent penetrating therethrough, and a first through-hole protrusion adjacent to the air vent and extending forwards the hollow ink tank body. The pressure regulator includes a holder, a resilient member arranged inside the holder, an elastic plate connected to the resilient member and abutting against the holder, a secure member disposed over the elastic plate, and a thin film covered the secure member. The pressure regulator further has a through-hole projection extending outwardly therefrom for connecting the hollow tube that connects to the first through-hole protrusion of the cover, so that the atmospheric air passes through the pressure regulator via the hollow tube after a sealing film is removed.
