Abstract
An ink cartridge for an ink jet printing device includes a rigid body having an ink chamber for containing ink within the body and an ink output port at one end of the body such that the ink within the ink chamber is output from the output port. A porous transmit medium is placed within the ink chamber and has one end adjacently connected to the ink output port such that the ink within the ink cavity is transmitted to the ink output cavity from the transmit medium by capillary action. The porous transmission medium is in an n-shaped form, including an input end, an output end, and an impermeable sheath between the input end and the output end. Thus, in the process of ink jet printing, at the instant when the ink within the ink output port is ejected, the porous transmit medium transmits the ink to the ink output chamber. As a result, no leakage of ink and smooth ink delivery are achieved. In addition, the structure of the cartridge is simple and assembly is early. The cartridge does not occupy space of the ink chamber.
