ABSTRACT:
A bubble generator includes a body with an inlet passage and outlet passages. Pumping means which comprises a pair of bellows, a plurality of first check plates, a plurality of second check plates, a pair of permanent magnets and a pair of electromagnets are disposed between the inlet passage and the outlet passages for pressurizing the air that flows through the inlet passage into the bellows and discharges it through the outlet passages. Noise-reducing means which comprises a first pipe having the same inner diameter as that of the outlet passage, a second pipe disposed concentrically with and in the first pipe, and a plurality of ribs supporting the second pipe at the first pipe are disposed in the middle of the outlet passages, for reducing noises caused by the pressurized air which is periodically pressurized by the pumping means and discharged into the outlet passages, by dispersing the pressurized air inside the outlet passages.
