ABSTRACT:
A method for adjusting an operation frequency and checking an operating state of the ultrasonic nebulizer is related in the present invention. By detecting the current to determine a resonance frequency and whether deviated from a predetermined normal range, the nebulizer can check the operating state and operate at the resonance frequency for increasing efficiency and saving power.
