Claim:
1. An ultrasonic nebulizer comprising: a circuit unit with a pre-determined electric power (W) for sending a voltage (V); a nebulization module for receiving the voltage (V) from the circuit unit; and a frequency sweeping unit for generating an operating frequency range of the nebulization module, sweeping frequency in the operating frequency range, determining a maximum current value (I) corresponding to a highest resonant frequency and sending the maximum current value (I) to the nebulization module, wherein the voltage (V) sent from the circuit unit is adjusted by multiplying a parameter (ΔC) to achieve a pre-determined voltage, wherein the parameter is obtained through a formula: W=(V×ΔC)×I, wherein W is measured in watts, V is measured in volts, and I is measured in amperes.
