In this embodiment, the diaphragm pump can provide 500-. Specifically, after the water inlet valve plate 20 is removed, the diaphragm cavity 141 of the diaphragm element 14 cannot be sealed, so that pulse water cannot be realized to reduce the pulse frequency, and meanwhile, after the water inlet valve plate 20 is removed, the pulse force can be increased to a certain extent to increase the water outlet pressure, so that the water outlet is smoother.

In this embodiment, the diaphragm chamber 141 has a water inlet 1411 and a water outlet 1412 respectively communicated with the diaphragm chamber 141, and the water inlet valve sheet 20 and the water outlet valve sheet 30 can be respectively matched with the water inlet 1411 and the water outlet 1412 in a sealing manner.

More specifically, the top of the water inlet valve 20 further comprises a fixing post 21 to facilitate the user to hold the water inlet valve in hand for disassembly and assembly.

In this embodiment, when the diaphragm element 14 is in the stretched position, the water outlet valve sheet 30 is in sealing fit with the diaphragm cavity 141; when the diaphragm element 14 is in the compressed position, the water inlet valve plate 20 is in sealing engagement with the diaphragm chamber 141. That is, the inlet valve piece 20 and the outlet valve piece 30 are both one-way valve pieces to realize that the inlet and outlet of the diaphragm chamber 141 do not interfere with each other.

In this embodiment, the number of the diaphragm elements 14 is equal to the number of the water outlet valve plates 30 and the number of the water inlet valve plates 20, wherein the water outlet valve plates 30 are integrated, and the water inlet valve plates 20 can be selectively disassembled.

The working principle of the invention is as follows: PV = NRT, when the volume of the sealed space becomes large, the pressure in the sealed space becomes small, and at this time, the water flow easily flows in, and when the volume of the sealed space becomes small, the pressure in the sealed space becomes large to pump out the water.

Therefore, the working process of the scheme is as follows: the power assembly 40 is started, the power source 41 drives the eccentric wheel 43, the eccentric wheel 43 drives the swing rod 45 to swing through the rolling piece 44 so as to drive the swinging piece 42 to swing, and the swinging piece 42 is matched with each diaphragm element 14 in sequence during swinging to control the diaphragm elements 14 to move between the stretching position and the compressing position. When the diaphragm element 14 is in the stretching position, the diaphragm element is in open fit with the water inlet valve plate 20, the volume of the diaphragm cavity 141 is increased, the pressure is reduced, water flows into the diaphragm cavity 141, when the diaphragm element 14 is in the compressing position, the diaphragm element is in open fit with the water outlet valve plate 30 to discharge water, the volume of the diaphragm cavity 141 is reduced, the pressure is increased, the water is pumped out of the diaphragm cavity 141, and therefore pulse water discharge of one diaphragm element 14 is completed. The oscillating member 42 cooperates with the other diaphragm element 14 for the next water pulse.
