Abstract

PURPOSE: To prevent an ultrasonic oscillator from loose driving when freezing and atomizing water is short by connecting a freezing detecting circuit with an oscillation circuit through a water level detecting circuit, etc.
CONSTITUTION: An oscillator mounting tube 3 wherein an ultrasonic oscillator B is fitted and fixed to the bottom is made from metal material of excellent conductivity, a freezing detecting circuit 12 is composed of a thermistor 10 fitted as a temperature sensor and a resistor R3 and the freezing detecting circuit 12 is connected with an oscillation circuit 16 through a reference voltage circuit 11, a voltage comparator A, a water level detecting circuit 14, an NAND circuit 15. Thereby, if the thermistor 10 senses freezing of atomizing water W, the partial voltage of a partial voltage output terminal 12a becomes smaller than that of the voltage output terminal 11a, as the output of the voltage comparator A takes a higher voltage, the water level switch is in an off state, the output of the NAND circuit takes a low voltage, the ultrasonic oscillator B is not driven. If the atomizing water W becomes short and the water level switch 7 turns on, the output of the water level detecting circuit 14 takes a higher voltage but the output of the voltage comparator A has a low voltage so that the ultrasonic oscillator B is not driven.
