Claims

[Claims for Utility Model Registration] (1) A reciprocating driving force is applied to a diaphragm provided to partition the inside of the casing to cause the diaphragm to bend, thereby urging the liquid inside the casing to separate the suction pipe and the discharge pipe. A diaphragm pump that transfers a fixed amount of the liquid by operating a check mechanism provided at a connection to the casing, respectively, a first magnet fixed to the diaphragm;
a second magnet whose surface facing the first magnet is magnetized to have the same polarity as the surface facing the first magnet, and which is disposed outside the casing and to which the reciprocating driving force is applied. diaphragm pump. (2) The diaphragm pump according to claim 1, wherein the fan is rotated by air force via an eccentric cam and a drive shaft to reciprocate the second magnet.
