An ink cartridge for an inkjet printer including an ink tank, a shelf, and a chip is provided. The ink tank has a handle, and two locking structures are disposed on the handle. One of the locking structures fits the shelf, and the other locking structure fits the printer. The ink tank has a pressure control valve mechanism for precisely controlling an internal negative pressure. The ink tank and the shelf are connected together with the locking structures. The chip is fixed on the shelf. Only the ink tank needs to be replaced. Thus, the resource is saved, and the cost is reduced. |
