Abstract
An ultrasonic humidifier comprising an atomizing chamber 2 containing water which is atomized by an ultrasonic vibration board 4 to be discharged therefrom. A water supply tank 11 is provided with a valve rod 14 having a valve 15 adapted to close a water outlet 13 thereof. The valve rod 14 protrudes by the elastic force of a spring. A water supply tank chamber 5 which, when said water supply tank is mounted therein with the valve rod 14 directed downward, relatively depresses the lower end of the valve rod with the bottom thereof to open the water outlet 13. A valve rod receiving chamber 6 communicates with the tank chamber. The water level of the atomizing chamber 2 is equal to the level of said water outlet 13 of the water supply tank which confronts with the valve rod receiving chamber 6. A water delivering path (17a or 17b) establishing communication between the valve rod receiving chamber 6 and the atomizing chamber is bent and elongated in a horizontal plane thereof.
