Abstract
An electromagnetic vibrating diaphragm pump is provided with a draining structure which can easily drain water flowed into the pump without a separate member preventing inflow of water. A first communicating passage is formed at a bottom end of a partition wall between a suction chamber and a compression chamber. A bottom portion inside the suction chamber slopes down toward the passage, making its compression chamber side lower than the suction chamber side. A second communicating passage is formed at a bottom end of a partition wall between an exhaust chamber and the compression chamber. A bottom portion inside the compression chamber slopes down toward the passage, making its exhaust chamber side lower than the compression chamber side. A bottom portion inside the exhaust chamber slopes down toward the exhaust port to make the exhaust port side lower. The exhaust port slopes down to make an outlet side thereof lower.
