<p>An air charger for generating air bubbles which can float and stable in water for a long period of time to attain water purification, activation or the like. The air charger comprises: a hollow rotating shaft (12) having an opening for introducing air; a capsule (14) mounted on the lower end of the rotating shaft (12); support means (20) for rotatably supporting the capsule (14) so as to locate the rotating shaft (12) in its upper end opening above the water surface and, at the same time, locating the capsule (14) in water; and drive means (13) for rotating the rotating shaft (12). The capsule (14) communicates with the interior of the hollow portion and has a plurality of small holes for spouting air bubbles into water, and the rotating shaft (12) is connected to the drive means (13) through a coupling.</p> |
