<P>PROBLEM TO BE SOLVED: To provide a bubble discharge device capable of atomizing bubbles (making microbubbles) discharged into water. <P>SOLUTION: The bubble discharge device includes: a pumping cylinder 7 anchored near the bottom of water while being held in an upright position; and an air-diffusing pipe member (bubble discharge part) 8 ejecting bubbles g into the pumping cylinder 7. The air pumping device (bubble discharge device) circulates, by means of the bubbles g, underlying water j pumped toward an upper end opening 7b from a lower end opening 7a of the pumping cylinder 7. The device includes an atomizing member 15 which is disposed so as to face the upper end opening 7b of the pumping cylinder 7 over a predetermined gap S2 and atomizes the bubbles g discharged into the water from the upper end opening 7b into microbubbles h by collision. <P>COPYRIGHT: (C)2013,JPO&INPIT |
