Ink-jet cartridge with a negative pressure ink reservoir |
摘要 |
An ink-jet cartridge with a negative pressure ink reservoir includes a rigid body provided with an ejecting device; an ink reservoir provided within the rigid body, the ink reservoir including two relatively movable plates and a plate body having resilience. The plate body is provided between the two flat plates, and is sealed with the circumferences of the two flat plates to form an enclosed ink reservoir. During ink-jet printing, the pressure within the ink reservoir decreases and the two plates move closer to each other to compress the plate body and the resilience of the plate body causes a negative pressure within the ink reservoir that prevents ink leakage from the ink-jet cartridge.
