Abstract
An ultrasonic atomizer utilizing surface acoustic waves is disclosed. The atomizer comprises an oscillator (11) generating surface acoustic waves, and a porous thin plate (12a) having a number of through holes arranged on n oscillating surface of the oscillator with a small clearance. A liquid (19) in a liquid container (18) is aspirated into the small clearance part between the oscillator and the porous thin plate by vibration by the surface acoustic waves or by capillarity. Vibration of the surface acoustic waves is transmitted to the porous thin plate (12a) through the liquid in the small clearance part, and a small quantity of liquid penetrating into holes of this thin plate is atomized by the vibration and sprayed to the exterior. According to this atomizer, it is possible to perform atomization by employing a battery of small power, and the balance between the supply quantity of the liquid and the atomization quantity can be kept excellent.
