[0002] The diaphragm pump is provided with circular motion by the motor, and the mechanical device makes the diaphragm in the pump do reciprocating motion, thereby compressing and stretching the air in the pump cavity. Under the action of the one-way valve, a pressure difference is generated between the water outlet or water inlet and the external atmospheric pressure. Under the action of the pressure difference, water is pressed into the water inlet and then discharged from the water outlet. This diaphragm pump has been widely used in small household appliances, medical equipment and other occasions.

[0003] At present, in order to increase the pressure of double-head diaphragm pumps on the market, conventional double-head diaphragm pumps are generally connected in series through external pipes when in use, but this will make the volume of the entire pump very large. Utility Model Content

A piston mechanism is symmetrically arranged on both sides of the eccentric shaft. The piston mechanism is drivingly connected to the output shaft of the motor through the eccentric shaft.

[0011] Both ends of the connecting pipeline have notches for placing sealing rings.

[0012] The air outlet of the left air outlet pipeline has a notch for placing a sealing ring, and the air inlet of the right air inlet pipeline has a notch for placing a sealing ring.

[0013] In summary, the present application includes at least one of the following beneficial technical effects: The new double-headed diaphragm pump realizes the function of series connection of double-headed pumps through an internal pipeline. One air outlet and one air inlet are respectively reduced on the upper pump bodies on both sides. By utilizing the wall thickness of the box body, a connecting pipeline is designed inside the side wall of the box body. In this way, without external pipelines, not only the function of series connection of double-headed pumps is realized, but also the volume of the entire pump is greatly reduced.
