WIPO Patent Application WO/2019/019154

A1

Disclosed is a diaphragm pump, comprising an electric motor (11), a diaphragm pump housing (12), and a transmission member (13), a metal diaphragm (14), a water inlet one-way valve (15) and a water outlet one-way valve (16) arranged in the diaphragm pump housing (12), wherein a drive shaft (17) of the electric motor (11) extends into the interior of the diaphragm pump housing (12) and is connected to the transmission member (13); the transmission member (13) is used to drive, under the drive of the electric motor (11), the metal diaphragm (14) to move in a reciprocating manner; the water inlet one-way valve (15) is in communication with an inner cavity of the diaphragm pump housing (12) for controlling liquid such that same flows into the diaphragm pump; and the water outlet one-way valve (16) is in communication with the inner cavity of the diaphragm pump housing (12) for controlling liquid so that same flows out of the diaphragm pump. By using the metal diaphragm (14) in the diaphragm pump, the service life of the diaphragm pump is prolonged, and the usage cost of the diaphragm pump is reduced.
