INKJET PRINT HEAD AND A MANUFACTURING METHOD FOR INKJET PRINT HEAD CAPABLE OF FORMING A UNIFORM PIEZO-ELECTRIC ACTUATOR BY MAINTAINING THE WIDTH AND HEIGHT OF THE PIEZO-ELECTRIC ACTUATOR THROUGH THE RECEIVING PORTION OF THE PIEZO-ELECTRIC ACTUATOR

摘要

PURPOSE: An inkjet print head and a manufacturing method for inkjet print head are provided to decrease the thickness of the membrane and increase the driving efficiency by accepting the piezo-electric actuator in the receiving portion.;CONSTITUTION: An inkjet print head(100) comprises a pressure chamber(50), a piezo-electric actuator receiving portion(20) and a piezo-electric actuator. The pressure chamber stores the discharged ink from the nozzle. The piezo-electric actuator receiving portion is formed in the form of the recessed groove from the external side corresponding to the pressure chamber to the pressure chamber. The viscous piezo-electric liquid is charged in the piezoelectric actuator containing part and solidified. The piezo-electric actuator is formed. The piezo-electric actuator offers the discharging driving force of the ink to the ink chamber.;COPYRIGHT KIPO 2012
