Abstract
A structure of an ink cartridge is provided. The structure includes a main body, a first sealing element and a second sealing element. The main body comprises a first, a second and a third chambers. The first chamber is separated with the second and the third chambers via a first partitioning plate. The second chamber is separated with the third chamber via a second partitioning plate. The first partitioning plate is substantially perpendicular to the second partitioning plate. The first, the second and the third chambers have a first, a second and a third exit ports at bases thereof. The first exit port is directly used as a first opening for flowing out the first ink. The first and second sealing elements cooperated with a bottom surface of the main body to define channels and openings for inks to flow therethrough.
