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.
An ultrasonic atomizing apparatus including an ultrasonic vibration generating means and an ultrasonic vibrator horn having a cylindrical section connected at one end of said ultrasonic vibration generating means and having a flared portion connected to the other end of the cylindrical section, said flared portion being flared and enlarged in diameter towards the tip end of the horn, said apparatus being adapted to atomized liquid material on said flared portion as the liquid material is supplied from liquid material supply means to the flared portion, characterized in that a hollow recess is formed in said flared portion, said hollow recess opening towards the tip of the horn, the geometry of said hollow recess being 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 substantially 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 having a single nodal point positioned above a boundary between said cylindrical section and the flared portion when said horn is ultrasonically excited.
An ultrasonic atomizing apparatus according to 1 wherein said flared portion has a conical and curved outer peripheral surface or trumpet-shaped surface.
An ultrasonic atomizing apparatus including an ultrasonic vibration generating means and an ultrasonic vibrator horn having a cylindrical section connected at one end to said ultrasonic vibration generating means and having a flared portion connected to the other end of the cylindrical section, said flared portion being flared and enlarged in diameter towards the tip end of the horn, said apparatus being adapted to atomize liquid material on said flared portion as the liquid material is supplied from liquid material supply means to the flared portion, characterized in that a hollow recess is formed in said flared portion, said hollow recess opening towards the tip of the horn, the geometry of said hollow recess being 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 substantially the same as the cross-sectional area of the flared portion in all other planes perpendicular to the longitudinal axis of the horn, said liquid material supply means having injection nozzle means for supplying the liquid material to said flared portion of the horn oriented at a predetermined angle so as to direct the liquid material against said horn at a feed point at or above a boundary between said cylindrical section and the flared portion.
