If the actual atomization rate is greater than the preset atomization rate, the control unit 7 transmits a voltage reduction signal to the atomization motor 204, and reduces the rotation speed by reducing the driving voltage of the atomization motor 204. If the actual atomization rate is smaller than the preset atomization rate, the control unit 7 transmits a pressurization signal to the atomization motor 204, increases the rotation speed by increasing the driving voltage of the atomization motor 204, and continues atomization when the driving voltage is adjusted.
