Abstract
In an ultrasonic atomizing device of the present disclosure, a raw material solution separation pipe is provided on a side surface of an atomization container. The raw material solution separation pipe has a raw material solution storage space for storing the raw material solution, and a raw material solution passage port for supplying and discharging the raw material solution to and from the raw material solution container. A liquid surface detection unit is provided in the vicinity of the raw material solution separation pipe. The liquid surface detection unit detects the level of the liquid level of the raw material solution in the raw material solution storage space, and outputs a liquid surface detection signal indicating the level of the detected liquid level.
Claims6
An ultrasonic atomizing device comprising:
- a raw material solution container for storing a raw material solution;
- an ultrasonic transducer provided below the raw material solution container;
- and
- a raw material solution separation pipe provided on a side surface of the raw material solution container and has a raw material solution storage space for storing the raw material solution, wherein
- the raw material solution separation pipe has a raw material solution passage port for supplying and discharging the raw material solution to and from the raw material solution container,
- the ultrasonic atomizing device further comprising
- a liquid surface detection unit configured to detect a liquid level of the raw material solution in the raw material solution storage space;
- a raw material tank provided independently of the raw material solution container and for storing the raw material solution;
- and
- a raw material solution increasing/decreasing mechanism configured to execute a raw material solution supply operation for supplying the raw material solution stored in the raw material tank into the raw material solution container, and a raw material solution discharging operation for discharging the raw material solution stored in the raw material solution container to the raw material tank, wherein
- the liquid surface detection unit is configured to output a liquid surface detection signal indicating the liquid level of the raw material solution,
- the ultrasonic atomizing device further comprising
- a control unit configured to receive the liquid surface detection signal from the liquid surface detection unit and control the raw material solution increasing/decreasing mechanism, wherein,
- based on the liquid surface detection signal, the control unit causes the raw material solution increasing/decreasing mechanism to execute the raw material solution supply operation and the raw material solution discharge operation to make the liquid level of the raw material solution reach a predetermined level.
