Problems to be Solved by the Invention However, in the above configuration, the intake air is sucked from around the jet water by the jet action of the water flow, so that only a relatively large bubble size is generated. This is because the air mass first comes into contact with the water flow in the laminar diffusion layer around the jet water having a low flow velocity, so that the air mass is reduced by the laminar shearing force. However, since the contact area between the water and the air is small, a large amount of energy is not transferred, and there is a limit to miniaturization.

Next, the air mass is transferred from the laminar boundary layer to the turbulent flow region, where it is refined by the turbulent shear force due to momentum conversion with water particles. Since very large energy is required, miniaturization is limited.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral 7 denotes a water tank, in which a circulation circuit 9 provided with a circulation pump 8 is provided. An ejection nozzle 10 is provided on the discharge side of the circulation pump 8. The other end of the jet nozzle 10 is connected to the water tank 7. On the other hand, on the downstream side of the jet nozzle 10, a small-diameter pipe 11 serving as an air supply means is provided so as to open to the water tank 7. The small-diameter pipe 11 is provided with an air pump 12 and a valve 13. Downstream of the small-diameter pipe 11, a wire net 14 as a porous body is provided.

In such a configuration, when the circulation pump 8 is operated,
The water sucked from the water tank 7 through the circulation circuit 9 becomes a high-speed water flow at the jet nozzle 10 having a reduced area and jets into the water tank 7. At the same time, the air pump 12 is operated to supply air from the small-diameter pipe 11 into the water tank 7. The air mass supplied in this way is blown off by the dynamic pressure energy of the water flow to form a fine air mass, which is mixed with the water flow to form a wire mesh.
Upon collision with 14, the microbubbles are further divided into microbubbles and sent to the water tank. These fine bubbles make the inside of the water tank cloudy.
Also, by adjusting the amount of air from the air pump 12, the amount of air bubbles can be changed, that is, the degree of cloudiness can be adjusted.
