ELECTROMAGNETIC OSCILLATION DIAPHRAGM PUMP

摘要

An object of the present invention is to provide an electromagnetic vibrating diaphragm pump with a draining structure which is a simple structure and can easily drain water having flowed into the pump without providing a separate member for preventing inflow of water. A first communicating passage P1 is formed at a bottom end of a partition wall W1 between a suction chamber 62 and a compression chamber 61, and a bottom portion 62a inside the suction chamber 62 slopes down toward the first communicating passage P1 such that the compression chamber 61 side thereof is lower than the suction chamber 62 side; a second communicating passage P2 is formed at a bottom end of a partition wall W2 between an exhaust chamber 63 and the compression chamber 61, and a bottom portion 61a inside the compression chamber 61 slopes down toward the second communicating passage such that the exhaust chamber 63 side thereof is lower than the compression chamber 61 side; and a bottom portion inside the exhaust chamber 63 slopes down toward the exhaust port such that the exhaust port side is made lower, and the exhaust port slopes down such that an outlet side thereof is made lower.
