A diaphragm pump comprises a pump body (21), a pump cover (22) and a diaphragm (1); the pump cover (22) is arranged on the pump body (21), the diaphragm (1) is located between the pump body (21) and the pump cover (22), the diaphragm (1) and the pump cover (22) jointly form a diaphragm cavity (27), and the diaphragm cavity (27) is provided with a liquid inlet and a liquid outlet. The diaphragm (1)comprises a diaphragm body (11) and a first fastener (12), and the first fastener (12) is fixedly connected with the middle of the diaphragm body (11) and used for connecting the diaphragm body (11)with the pump body (21); the diaphragm body (11) can be driven to deform through the first fastener (12) so as to change the size of the diaphragm cavity (27), so that the diaphragm (1) discharges liquid in the diaphragm cavity (27) from the liquid outlet or sucks the liquid from the liquid inlet. The connection between the diaphragm body (11) and the pump body (21) is realized by adopting the first fastener (12); due to the fact that the first fastener (12) is convenient to disassemble and assemble, separation of the diaphragm (1) and the pump body (21) can be achieved by disassembling the first fastener (12) from the pump body (21), the diaphragm (1) can be easily disassembled from the pump body (21) and can also be conveniently installed back to the pump body (21), and then the diaphragm (1) can be conveniently replaced or maintained.

    一种隔膜泵,包括泵体(21)、泵盖(22)和隔膜(1)。泵盖(22)设置在泵体(21)上,隔膜(1)位于泵体(21)与泵盖(22)之间,隔膜(1)与泵盖(22)共同形成隔膜腔(27),隔膜腔(27)设有进液口以及出液口。隔膜(1)包括隔膜本体(11)及第一紧固件(12),第一紧固件(12)与隔膜本体(11)的中部固定连接,用于隔膜本体(11)与泵体(21)之间的连接;通过第一紧固件(12)能够带动隔膜本体(11)变形,以改变隔膜腔(27)的大小,使得隔膜(1)将隔膜腔(27)的液体从出液口排出,或从进液口吸入液体。采用第一紧固件(12)实现隔膜本体(11)与泵体(21)之间的连接,由于第一紧固件(12)方便拆卸与安装,将第一紧固件(12)从泵体(21)上拆卸下来,可以实现隔膜(1)与泵体(21)的分离,从而能够将隔膜(1)能够容易的从泵体(21)上拆下,也能方便的安装回泵体(21),进而可以方便的对隔膜(1)进行更换或维修。
