When the pressure reducing pump is operated, oxygen is guided to the ozone generating element, and oxygen is generated into ozone. Ozone is stirred with supplied water by a spiral stirring section, and the ozone is melted into water to become ozone water. This ozone water is stored in a water storage tank.

According to a second aspect of the present invention, the oxygen is high-concentration oxygen generated from an oxygen concentrator having a filter and a zeolite adsorbent therein and having an adsorption column for adsorbing and separating nitrogen.

[0007] The air outside the oxygen concentrator is drawn in by a decompression pump, air dust is removed by a filter of the oxygen concentrator, and nitrogen in the air is adsorbed and separated by an adsorption column having a zeolite adsorbent. High-concentration oxygen is obtained at the outlet. Thereby, a large amount of ozone generated from the high-concentration oxygen guided to the ozone generation element can be obtained.

And a decompression pump 8 that draws air into the oxygen concentrator 4, the ozone generation element 3, and the stirring unit 6.
The decompression pump 8 is provided to reduce the degree of melting of oxygen containing excess ozone in the water storage tank 7 and to promote recovery in a gas phase. Reference numeral 9 denotes a water stopcock for opening and closing water.

The cylindrical pipe 2 is provided with a water supply passage 21 through which the supplied water flows, a shielding plate 22 for shielding and dividing the ozone generation element 3 from the water flowing through the water supply path 21, and a discharge from the ozone generation element 3. And an ozone supply pipe 24.

The ozone generating element 3 includes a dielectric 32,
And an electrode 31 provided thereon.
A high voltage from a high voltage power supply 5 is applied to 1 to discharge it,
The oxygen in the ozone generating element 3 is converted into ozone. In addition,
The ozone generation efficiency can be increased by making the electrode 31 sinusoidal or by providing many fine protrusions to increase the area.

The oxygen concentrator 4 is provided with a filter 42 for removing dust from the inflowing air 40, and adsorption tubes 43 and 44 having a zeolite adsorbent and adsorbing and separating nitrogen. Discharge.

Now, when the decompression pump 8 is operated, the air 40 is guided to the oxygen concentrator 4 and dust is removed to the bacterial level by the filter 42.
The nitrogen is adsorbed and separated by 44 and the air 40 is, for example, 9
It is converted into clean high-concentration oxygen 41 of 0% or more.

The high-concentration oxygen 4 obtained by the oxygen concentrator 4
1 is guided to the ozone generating element 3 and discharge occurs when a high frequency power supply of the high voltage power supply 5 is applied to the electrode 31;
Ozone is generated from high concentration oxygen. Then, it is supplied from the ozone supply pipe 24 to the stirring section 6.

When the water stopcock 9 is opened, water is supplied to the stirring unit 6 through the water supply passage 21 of the cylindrical tube 2. When ozone and water pass through the spiral stirring section 6, the ozone is dissolved in the water by stirring and ozone water is generated.

The ozone water stored in the water storage tank 7 is introduced into the ultrasonic neo-lyzer to atomize the ozone water to improve the environment such as sterilization and deodorization in homes and offices, and MRSA in hospitals. Provided for medical use such as infection control.
