PURPOSE:To incorporate fine particles of air into a wide range of water by supplying the air from the hollow part of a revolving shaft into the swirling water flow generated in a water flow generator to create the air in the swirling water flow and cutting off the air from said air flow by the waves of the swirling water flow. CONSTITUTION:The water flow generator 1 which generates the water flow by rotating vanes 2 provided to the revolving shaft 3 is formed with the end part of the shaft 3 as the hollow part 3a opened at the front end. An air chamber 10 is provided between the shaft 3 and the water flow generator body 1a by providing shaft sealing to the front and rear. An air supply pipe 11 is communicated with the air chamber 10 from the outside and a communicating hole 13 is bored to the shaft 3 to communicate the hollow part 3a and the air chamber 10. More specifically, the air is sucked out of the inside of the shaft 3 by the swirling water flow JF generated forward from the vanes 2 and the air flow AF is generated in the water, by which the air is cut off from the liquid JFW of the swirling water flow and is incorporated in the form of the fine particles into the water over a long distance. |
