Abstract

The invention discloses a diaphragm pump and a pump head structure thereof. The pump head structure comprises a transmission head, a diaphragm and a valve seat which are sequentially arranged in the direction of an output shaft of a motor, and the diaphragm is provided with a first surface matched with the transmission head and a second surface matched with the valve seat; a plurality of wading parts capable of making contact with fluid are arranged on the second surface, a pressurizing cavity is formed between each wading part and the valve seat, and the area ratio of the wading parts to thediaphragm is 50%-70%. According to the diaphragm pump and the pump head structure thereof, parameters such as the water outlet flow and the working efficiency of the diaphragm pump can be improved under the condition that it is guaranteed that the size of the diaphragm pump is not changed and the structural durability is good, and therefore the requirements of users for high performance, low cost,low noise, small size and the like of the diaphragm pump are met.

Description

technical field [0001] The invention relates to the technical field of diaphragm pumps, in particular to a diaphragm pump and a pump head structure thereof. Background technique [0002] Diaphragm pumps are mechanical structures that deliver liquids or pressurize liquids through a diaphragm. The existing diaphragm pump can use a reciprocating drive member to drive the diaphragm to deform to achieve the purpose of sucking liquid; it can also be driven by a driving member such as a nutating disc or a swinging disc to drive the diaphragm to deform to achieve the purpose of suctioning liquid. Diaphragm pumps are widely used in water purification and other industries. [0003] At present, the diaphragm pumps provided by manufacturers are largely standardized into several fixed models. Different types of diaphragm pumps correspond to parameters such as predetermined water flow and fixed volume. In general, the larger the water flow of the diaphragm pump, the larger its volume. ...
