The present invention relates to a nano-bubble generator, and more particularly, to a nano-bubble generator, wherein the diameter of the bubble or micro-bubble is 5μm or less. The nano-bubble generator in the present invention comprises the following: a cylindrical body (15) connected to a fluid inlet pipe (12) and an air inlet pipe (11) for receiving fluid and air as external sources; an impeller (20), which is rotatable while creating nano-bubbles, attached to the inner side of the body (15); a first wall (30) and a second wall (31) having a hole at the center wherein nano-bubbles can pass by, attached to the body(15) while supporting an operating axis (S); a fan (40), attached to a side of the operating axis (S) for discharging nano-bubbles passed by the first wall (30) to a discharging pipe (50); the discharging pipe (50) having a honeycomb (51) for stabilizing fluid flow including nano-bubbles which are discharged by the fan (40); and a motor (M) for operating the operating axis (S) protruding from the body (15), attached to the fan (40) and impeller (20), for rotating the fan (40) and impeller (20). |
