<p>PURPOSE:To provide a cheap, compact and light-weight device to form a large amount of minor sized bubbles by a method wherein a hollow body of cylindrical cross section and having many holes on the peripheral wall is installed to the end of a hollow pipe and is rotated at a high-speed. CONSTITUTION:When the driving part such as motor or generator is activated, the bubble generating part member 4 and the hollow pipe 5 are rotated at a high-speed. This generates a negative pressure near the holes 7 on the outer periphery of the bubble generating part member 4, by which the air is sucked from the hollow section 9 and minor bubbles are generated. At this time, by shifting the depth and position of the holes 7 in the hollow section 9, the chance is reduced that generated bubbles collide mutually and grow into large bubbles. In this manner, such a compact and light-weight device can produce a large amount of very small bubbles.</p> |
