An ink cartridge comprises a cartridge body and a cartridge cover for sealing and covering the cartridge body. The cartridge cover is provided with an ink filling hole for filling ink and an air hole for communicating with atmosphere outside. An ink storing chamber for storing ink, an adjusting chamber, a buoy induction chamber and a shading buoy are arranged in the cartridge body in series. A sealing platform is provided at the top of the ink storing chamber. The upper surface of the sealing platform is provided with an air guiding column connecting with the air hole, and the lower surface of it is provided with an ink feeding tube for feeding ink to the adjusting chamber. The adjusting chamber and the buoy induction chamber are communicated with each other via upper and lower through-hole.
