- the water that was initially in the hollow interior of the rotary shaft 12 is ejected from the bubble discharge holes 62 of the capsule 14 by centrifugal force, and then the rotary shaft 12 is opened. Fresh air is sucked into the rotating shaft from the mouth, and the air is vigorously ejected as bubbles from the bubble discharge holes 62 of the capsule 14.
- a negative pressure is generated around the lower part of the outer cylinder 70 due to the high-speed rotation of the capsule, and air is drawn into the space between the outer cylinder and the rotating shaft through the upper end opening of the outer cylinder.
- the water jet in the substantially radial direction (substantially spiral shape) centering on the capsule 14 is generated immediately below and near the lower end opening 74 of the outer cylinder 70 by the jet bubbles from the bubble discharge holes 62.

- One of these bubbles has a diameter of 1/1000 nm! ⁇ 3100mm, fine, and therefore has low buoyancy and stays suspended in water for a long time.
- each bubble is less likely to coalesce in water and remains a closed cell for a considerable amount of time.
- Such microbubbles penetrate deeply into water, spread more widely, and stay for a long time.
- oxygen and nitrogen in the air come into contact with water for a long time and migrate into the water, decomposing and removing toxic gases and organic substances such as ammonia in the water, farming and fishing grounds, cultivation of fish and shellfish, and hydroponic water. High ability to purify etc.
- the air generates static electricity due to friction with the outer peripheral surface of the rotating shaft 12 and the like, and the air bubbles float in water for a long time, and then burst and enter the air. It emits, but generates ultrasonic waves during this rupture.
- the generated static electricity causes a potential difference in the water, and ionizes the water to cause ionization of the cation H + and the hidden ion OH— in the water.
- Negative static electricity becomes more charged, which attracts cations + in the water. Therefore, the hidden ions ⁇ H— increase relatively in the water, and the water becomes alkaline ionized water.
