Abstract
An ultrasonic atomizing device includes an ultrasonic oscillator system and a housing. The oscillator system comprises a conic-frustum shaped coupler having a projection at the central portion of its large cross-sectional portion, a circular piezoelectric plate provided with electrode plates and having a center hole through which being penetrated the projection, and a resonance plate to be stimulated into vibration. On the other hand, the housing includes a cylindrical wall, a circular cover fixed at one end of the cylindrical wall and a ring shaped cover fixed at the other end of the cylindrical wall. A circular hole of the ring shaped cover accepts and flexibly supports the coupler through a ring shaped rubber packing. The surface of the oscillator is sealed with the housing by fixing the circular cover to the projection by means of screws, in order to prevent invasion or adhesion of liquid to the surface of the oscillator.
