Abstract
This liquid surface detection device comprises: a liquid retention part in which hydrogen peroxide water is retained, the hydrogen peroxide water to be atomized by a vibrating plate in which a through-hole is provided; a float positioned inside the liquid retention part; and a sensor that detects, via the float, the arrival of the liquid surface of the hydrogen peroxide water retained in the liquid retention device at a prescribed position.
Claims17
A liquid level detection device comprising:
- a liquid reservoir configured to store hydrogen peroxide solution to be atomized by a diaphragm having a through hole;
- a float disposed in the liquid reservoir;
- and
- a sensor configured to detect a fact that a liquid level of the hydrogen peroxide solution stored in the liquid reservoir has reached a predetermined position, by using the float, wherein:
- the liquid reservoir includes a detecting reservoir and a liquid supplying reservoir connected to the detecting reservoir by a connection tube at a position lower than the predetermined position in a vertical direction,
- the connection tube is connected to a bottom of the detecting reservoir and a bottom of the detecting reservoir, and
- the float is disposed in the detecting reservoir.
