Abstract

The invention discloses a diaphragm pump and a water treatment device. The diaphragm pump comprises a housing and a spacer; the inner wall of the housing has a sealing boss; the spacer is disposed inside the housing; the spacer and the housing form a water-receiving cavity; a connection portion and a connection hole which match each other are arranged on one end facing the spacer, of the sealing boss, and the spacer respectively, and the connecting portion is inserted into the connection hole; a first sealing member is arranged between the connection portion and a side wall of the connection hole so as to allow the sealing boss and the spacer to be connected in a sealed manner; the sealing boss divides the water receiving cavity into a high pressure cavity and a low pressure cavity. The technical scheme of the invention can improve the reliability of the diaphragm pump.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a diaphragm pump and water treatment equipment. Background technique [0002] Diaphragm pump is a kind of pump that can be used in water treatment equipment. The low-pressure chamber, pressurized chamber and high-pressure chamber are separated in the diaphragm pump by housing, separator and diaphragm. In order to avoid the loss of pressure in the high-pressure chamber caused by the direct connection between the low-pressure chamber and the high-pressure chamber, the low-pressure chamber and the high-pressure chamber need to be isolated by a sealed connection. Such as figure 1 As shown, in the prior art, the sealed connection can be made by inserting the connecting part 300' into the connecting hole 400', and setting a sealing member 500 between the end of the connecting part 300' and the bottom wall of the connecting hole 400' 'accomplish. Wherein, the sealing member 500' ...
