In the opening 16 at the center of the channel forming plate 15,
The pumping pipe 17 is inserted.

The pumping pipe 17 is formed in a shape whose inner diameter gradually increases from the lower end to the upper end. As shown in FIG. 1, the lower end of the pumping pipe 17 is provided with water stored in the main body 10. 14 so as to be immersed in the pumping pipe 17.
A ring-shaped spray plate 19 is fixed to the upper edge of the nozzle.

The spray plate 19 extends radially outward from the upper edge of the pumping pipe 17 concentrically with the pumping pipe 17 and faces the upper surface of the flow path forming plate 15 at an interval. .

On the lower surface of the spray plate 19, a large number of intake blades 20 are radially attached from the center of the spray plate 19 at equal intervals in the circumferential direction, as shown in FIG.

A cross-shaped support rod 21 is fixed to the upper inner surface of the spray plate 19, and the lower end of a rotating shaft 23 of a drive source 22 such as a motor mounted on the center of the upper surface of the main body 10 has a cross-shaped shape. Is connected to the center of the support rod 21.

That is, when the drive source 22 is actuated, the rotational force of the drive source 22 is transmitted to the spray plate 19 via the support rod 21, and the pumping pipe 17 and a number of intake blades 20 move the spray plate 1
9 and rotate together.

Around the spray plate 19, a number of water droplet colliding members 24 are arranged at minute intervals in the circumferential direction.

The upper and lower ends of the water droplet colliding member 24 are
An annular support member 27 located at an upper portion inside the main body 10,

Due to the centrifugal force caused by this rotation, the water 14 located inside the pumping pipe 17 inside the main body 10 rises along the inner surface of the pumping pipe 17 and reaches the central upper surface of the spray plate 19, The upper surface of the spray plate 19 is radiated outward in the radial direction as water droplets and scatters, and collides with the water droplet colliding member 24 to be atomized as fine water particles.

On the other hand, when the intake blade 20 rotates together with the spray plate 19, air on the lower surface side of the flow path forming plate 15 is sucked upward through the opening 16, whereby air outside the main body 10 is removed. The air is sucked into the main body 10 from the air inlet 12 through the ozone generator 13.

At this time, when corona discharge is generated by the electrode surface of the ozone generator 13, ozone is generated from oxygen in air flowing inside the structure 18 of the ozone generator 13, and ozone is generated inside the main body 10. Will be supplied.

When the water 14 is supplied from a water supply or the like to the water supply pipe 26 and water is continuously dropped near the center of the spray plate 25 and the drive source 22 is operated, the rotational force of the drive source 22 is increased. Is transmitted to the spray plate 25 via the support rod 21, and the pumping pipe 17 and the many intake blades 20 rotate integrally with the spray plate 25.

As a result, the water 14 dropped near the center of the spray plate 25 scatters as water droplets radially outward on the upper surface of the spray plate 25 by centrifugal force, and collides with the water droplet collision member 24. Atomized into fine water droplets.

On the other hand, when the intake blade 20 rotates together with the spray plate 25, air on the lower surface side of the flow path forming plate 15 is sucked upward through the opening 16, whereby the air outside the main body 10 generates ozone. The air is sucked into the main body 10 from the air inlet 12 through the container 13.

At this time, when corona discharge is generated by the electrode surface of the ozone generator 13, ozone is generated from oxygen in air flowing inside the structure 18 of the ozone generator 13, and ozone is generated inside the main body 10. Will be supplied.

The ozone arriving at the outer periphery of the spray plate 25 collides with the water droplet colliding member 24 and mixes with the fine water particles atomized to form highly active hydroxyl radicals from the ozone and water molecules. Ozone Fog F
Is discharged from the discharge port 11 to the outside of the main body 10 through the space between the water droplet collision members 24, and the odor component mixed with the air is oxidized and removed.

As described above, in the ozone fog generator shown in FIG. 5, water droplets scattered by the rotation of the spray plate 25 are made to collide with the water droplet colliding member 24 to form fine water droplets. Since ozone sucked by 20 is mixed with fine water particles, ozone fog F can be generated without using atomizing nozzle 4 (see FIG. 6).

The water 14 is supplied from the water supply pipe 26 to the spray plate 25.
, The size of the main body 10 can be reduced, and since the water 14 is not always stored, there is no need to perform water quality management.

The ozone fog generator according to the present invention is not limited to the above-described embodiment, but various changes can be made without departing from the scope of the present invention.
