MOVABLE INK EJECTION STRUCTURE WITH ENDLESS WALLS |
摘要 |
A nozzle arrangement for an ink jet printhead. The nozzle arrangement includes a wafer substrate arrangement defining an ink inlet channel and a first wall surrounding the ink inlet channel; a movable ink ejection structure defining an ink ejection port and a second wall surrounding the first wall so that the wafer substrate arrangement and ink ejection structure together define a nozzle chamber in fluid communication with the ink inlet channel and the ink ejection port; and a plurality of thermal bend actuators movably coupling the ink ejection structure to the wafer substrate arrangement. Each actuator includes an arm for moving the ink ejection structure responsive to an applied electrical signal, whereby a volume of the nozzle chamber is varied. Each wall is endless.
