INK EJECTION MECHANISM WITH THERMAL ACTUATOR COIL |
摘要 |
A micro-electromechanical ejection mechanism is disclosed for ejecting an ink droplet. The mechanism has a wafer substrate and an ink chamber formed on the wafer substrate. The ink chamber has an ink ejection nozzle formed in a roof thereof and an ink inlet port formed in a floor thereof. A paddle device is arranged inside the ink chamber between the inlet port and the ejection nozzle A bi-layer thermal actuator coil is also included with a first end thereof fast with the substrate and a second end connected to the paddle device. Heating of the thermal actuator coil displaces the paddle device, causing ejection of an ink droplet through the ink ejection nozzle.
