  The present invention relates to an ultrasonic atomizer that atomizes large-diameter particles with a low-frequency transmission vibrator and atomizes the large-diameter particles into small-diameter particles with a high-frequency atomizing vibrator.

  2. Description of the Related Art Conventionally, as this type of ultrasonic atomizer, as shown in FIG. 2, an atomizing container B is configured inside a casing A, and a liquid D atomized from a tank C is predetermined in the atomizing container B.

The thing in which the spout K was provided between J is proposed.

  In the conventional ultrasonic atomizer configured as described above, when an oscillation output is supplied from the oscillator F to the ultrasonic vibrator E, ultrasonic waves are generated from the ultrasonic vibrator E and injected into the atomization container B. The generated liquid column D1 of the liquid D is generated, and the atomized particles D2 are broken and atomized from the liquid column D1, and when the fan G is driven, the generated atomized particles D2 are disposed above the pipe member H. Here, the large-diameter particles of the atomized particles D2 fall by gravity in the course of ascending the pipe member H, and only the small-diameter particles D2 rise by the air in the pipe H, It is comprised so that it may be ejected from K.

However, in the conventional ultrasonic atomizer configured as described above, the atomized particles having a large diameter are dropped in the middle of the pipe H while the particles atomized by the ultrasonic vibrator E are blown to the pipe member H. In this configuration, only a small diameter of the atomized particles is blown from the pipe, but the configuration in which only a part of the atomized particles is taken out is very atomized. There was a problem of inefficiency.
