PURPOSE: A microbubble generating device is provided to prevent the corrosion of mechanical parts due to a cavitation phenomenon generated by the rotation of an impeller and to generate fine bubbles by generating the vortexes of water and inflow air to opposite directions. CONSTITUTION: A microbubble generating device comprises a pump (10), an ejector (20), a discharging pipe (30), a spiral groove socket (40), and an air injecting pipe. The pump comprises a fluid inlet (12) and an outlet. Fluid flows through the inlet and is discharged by the torque of an impeller (16) in connection with a motor (14). One side of the ejector is in connection with the outlet of the pump. The discharging pipe is installed on another side of the ejector. One part in the spiral groove socket with a spiral groove is in connection with one end of the ejector. The air injecting pipe is in connection with another part of the spiral groove socket. Another part of the spiral groove socket is expanded on the surface of water. |
