ABSTRACT:
An ultrasonic atomizing apparatus including an ultrasonic vibration generator and an ultrasonic vibrator horn having a cylindrical section connected at one end to the ultrasonic vibration generator and having a flared portion connected to the other end of the cylindrical section. The flared portion is flared and enlarged in diameter towards the tip end of the horn and is adapted to atomize liquid material on the flared portion as the liquid material is supplied from a liquid material supply nozzle to the flared portion. A hollow recess is formed in the flared portion opening toward the tip end of the horn. The geometry of the hollow recess is such that the cross-sectional area of the flared portion of the horn in any plane perpendicular to the longitudinal axis of the horn is the same as the cross-sectional area of the flared portion in all other planes perpendicular to the longitudinal axis of the horn. The horn also has a single nodal point positioned above a boundary between the cylindrical section and the flared portion when the horn is ultrasonically excited.
