である。When the switch 5 is turned on, a high-frequency voltage having a frequency equal to the mechanical resonance frequency of the metal horn 16 generated by the oscillation circuit section 8 is applied to the electrostrictive element 11 by the feed line 12 and generated by the electrostrictive element 11. Ultrasonic vibration metal horn 16
Vibrates together with the atomization surface 21 at the tip of the metal horn 16
Is greatly vibrated by the vibration expanding action of the metal horn 16. On the other hand, water is supplied to the water supply body 14 from the water supply tank 3 to the tip by capillary action. The water thus supplied is supplied to the atomization surface 21 of the metal horn 16 and atomized and sprayed by ultrasonic vibration energy. . Then, in the steady spray state, the water is continuously atomized from the metal horn 16, and the water in the water supply tank 3 decreases. When the water in the water supply tank 3 decreases to a level at which water cannot be supplied to the water supply body 14, it is necessary to replenish the water in the water supply tank 3. At this time, the water supply tank 3 is pulled out downward, water is supplied, and the fitting opening 3a is press-fitted and set in the fitting cylindrical portion 9a of the vibration horn holding frame 9 again in the same manner.
