摘要： An ink-jet cartridge adapted to be used for a thermal ink-jet printer is disclosed. The ink-jet cartridge includes a housing for storing the ink in an interior thereof, a printhead having a plurality of orifices thereon for allowing the ink to be Jetted therethrough when the thermal ink-jet printer is printing, and a pressure-adjusting device disposed in the housing for regulating a back pressure of the interior of the housing, wherein the pressure-adjusting device includes a first opening fixed on an upper portion of the housing and exposed to an ambient atmosphere, and a second opening disposed at a bottom of the interior of the housing and having at least one regulating hole thereon. Each regulating hole has a cross-sectional area being smaller than that of the first opening for maintaining the back pressure when the ink-jet cartridge is inverted.
