PURPOSE: To improve working efficiency simultaneously with an increase in a heat dissipation effect, by a method wherein a transistor for an ultrasonic oscillation is secured to a shield case formed integrally with a chamber base, a printed circuit substrate with a built-in ultrasonic vibrator oscillating circuit part is contained for securing.
CONSTITUTION: After the surface of an ultrasonic vibrator 1 is filled with water, a given input voltage is applied on an ultrasonic moistening unit to oscillate an oscillating circuit part 5. Oscillation is inputted to a transistor 7 for amplification to drive the ultrasonic vibrator 1, and its energy is propagated to a chamber base 11a and water on the surface of the ultrasonic vibrator 1 to vibrate the water. A part thereof is formed in a spray as it forms a sprayed column, and is fed to the outside with the aid of a fan motor. A printed circuit substrate 6 with the built-in oscillating circuit part 5 and the transistor 7 are electrically shielded to a shield case 11b formed integrally with the chamber base 11a, and this causes propagation of a heat, generated by the thermally excellently secured transistor 7, to the shield case 11b and the chamber base 11a, and cases emission of the heat in the air or water for spray or fog.
