Claims

[Claims for Utility Model Registration] (1) A float switch 7 is arranged in a water tank 1 in which an ultrasonic transducer 2 is arranged at the bottom, and a water supply solenoid is arranged in a water supply pipe 5 that supplies water to the water tank 1. The valve 6 is operated by the action of the float switch 7,
In an ultrasonic humidifier, the water level in the water tank 1 is kept constant by closing the valve when the water level in the water tank 1 is above a certain water level and opening the valve when the water level is below a certain water level. A sensor 8 is disposed, and when an overflow pipe 9 opens in the water tank 1 at a position higher than the certain water level, and the water temperature in the water tank 1 rises to a certain temperature, the water supply solenoid valve 6 opens regardless of the water level. While the water is supplied to the water tank 1 through the valve, the water in the water tank 1 flows out from the overflow pipe 9 and the water temperature decreases, and when the water temperature becomes below a certain temperature, the water supply solenoid valve 6 closes. An ultrasonic humidifier that is characterized by stopping water supply. (2) A float switch 7 is disposed in a water tank 1 in which an ultrasonic transducer 2 is disposed at the bottom, and a water supply electromagnetic valve 6 disposed in a water supply pipe 5 that supplies water to the water tank 1 controls the flow of the float switch 7. By the action,
The drain solenoid valve 21 is an ultrasonic humidifier that closes when the water level in the water tank 1 is above a certain water level and opens when the water level is below a certain water level to keep the water level in the water tank 1 constant. When the water temperature rises to a certain level, the drain valve 21 is activated by the water temperature sensor 8 disposed in the aquarium 1 when the water temperature rises to a certain level.
is opened, and as the water level drops, the float switch 7 acts to open the water supply solenoid valve 6, and when the water temperature drops below a certain temperature due to water supply, the drain solenoid valve 21 closes. An ultrasonic humidifier in which the water supply solenoid valve 6 closes when the water level in the water tank returns to the constant water level.
