Abstract
A liquid atomizer utilizes a plurality of laminated piezoelectric elements for converting electrical oscillation into mechanical vibration, a circuit for generating resonance frequency of a low DC voltage, the circuit being electrically connected to the piezoelectric elements and including a charging circuit for forcibly causing electric charge based on said DC resonance frequency voltage to flow from a DC power source into the laminated piezoelectric elements and a discharge circuit for forcibly causing electric charge stored in the laminated piezoelectric elements to be discharged.
