Abstract
This ultrasonic atomizer includes an oscillating member, a means for vibrating the oscillating member at a supersonic frequency, a bottle for liquid storage, with an opening, fitted generally above the oscillating member with regard to the preferred orientation of the atomizer during use, and a nozzle fitted into the opening of the bottle, this nozzle having a tip portion protruding outside the bottle in the generally downwards direction and approached closely to the oscillating member. The nozzle is formed with a fine groove for leading liquid in the bottle downwards to the tip portion of the nozzle by capillary action and by gravitational action, and with an aperture for introducing air from the outside into the bottle. Thereby liquid in the bottle may be properly supplied to the oscillating member to be atomized in a controlled fashion, and interruption of liquid supply and also dribbling of liquid are positively prevented. Constructions for the nozzle and for the bottle are also disclosed.
