(Action)
Next, the operation of the atomizer of the present embodiment will be described. When the atomizer of this embodiment is started to operate with the storage chamber 11 containing the slightly acidic hypochlorous acid water set at a predetermined position of the base portion 2, the atomizer chamber is vibrated by the vibration of the ultrasonic vibrator 16. Mist is generated in 12.

The generated mist is discharged to the outside by the air taken in by the fan 26. Specifically, the air taken into the lower chamber 21g by the fan 26 is sent out into the front part 3 by the fan 26, and is sent from the front part vent 32e on the back side of the front part 3 to the storage chamber vent 11f. And, it is sent out into the first space 12d of the atomization chamber 12 through the intake port 12j. The air sent into the first space 12d is sent out into the second space 12e, and the generated mist is discharged to the outside from the lid opening 12i and the louver device 13e by the air sent into the second space 12e. To.

In the atomizer of the present embodiment, when the remaining amount of the liquid in the atomization chamber 12 becomes low, the supply port 12h opens and the liquid in the storage chamber 11 automatically enters the atomization chamber main body 12a (storage unit 11i). Is supplied to. Specifically, when the second water level sensor 18b detects that the remaining amount of liquid in the atomization chamber main body 12a (storage unit 11i) is equal to or less than the lower limit value, a current is supplied to the electromagnetic coil 27. A magnetic force is generated. When the on-off valve 20a is lifted by the magnetic force, the supply port 12h opens, the storage chamber 11 and the atomization chamber 12 communicate with each other, and the liquid in the storage chamber 11 is supplied into the atomization chamber main body 12a (storage unit 11i). ..

On the other hand, when the first water level sensor 18a detects that the amount of liquid in the atomization chamber main body 12a (reservoir 11i) has reached the upper limit, the supply of current to the electromagnetic coil 27 is stopped and the on-off valve is stopped. 20a is lowered and the supply port 12h is closed. As a result, the supply of the liquid from the storage chamber 11 into the atomization chamber main body 12a (storage unit 11i) is stopped.

In the atomizer of this embodiment, when the second water level sensor 18b detects that the water level has reached the lower limit value and there is no liquid to be supplied into the atomizing chamber 12 in the tank 1, the atomizer of this embodiment is used. The operation of the atomizer is stopped.

The atomizer of the present invention can be used not only at home but also in various facilities such as hospitals, nursing care facilities, schools, and libraries.
