A GENERATOR OF MICROBUBBLE

摘要

PURPOSE: A microbubble generator is provided to be able to stably maintain the microbubble generation by keeping the rotation angle of a generating member at 180 degrees with a control means, and preventing the rotation of an excessive rotation angle or an insufficient rotation angle. CONSTITUTION: A microbubble generator comprises a body (5), a generating member (7), a rotary shaft (8), a driver, a pair of detection sensors, and a control means. A generation room (4) equipped with an inlet (2) of feeding water including bubbles and an outlet (3) is equipped in the body. The outer periphery of the generating member is accommodated in the state of being tightly adhered to the inner periphery of the generation room of the body. Multiple fine pipelines (6) are formed in the generating member in the progressive direction of feeding water. The rotary shaft penetrates into the body, and is fixed to the generating member on one end and exposed to outside of the body on the other end. A pair of the detection sensors detect if the detection sensors contact an operation link rotating in gear with the rotary shaft. The control means controls the driving of a motor (9) according to the detection of the detection sensors. A pair of the detection sensors is positioned at a position restricting the rotation angle of the operation link to 180 degrees, respectively.
