Abstract
The present invention relates to an ink cartridge for an ink jet printer, comprising an ink storage chamber formed by a concave housing (3) and a flexible and deformable film (2), a fluid outlet (5) connected with a fluid inlet of the printer, an information storage device (11), a locking mechanism (6) and a detection mechanism for detecting ink consumption. The detection mechanism comprises a lever component (4) positioned in the ink storage chamber and a force transmission component (10) positioned on the housing, made of deformable material and communicated with the ink storage chamber. This ink cartridge can solve the technical problems that the conventional detection mechanism of the ink cartridge of the ink jet printer is complex and low in reliability.
