Technical Field

The invention relates to the field of micropumps, in particular to an electromagnetic diaphragm pump.

Background

The noise that produces when traditional liquid pump motor rotation work is the very disgust shortcoming of user, directly influences user's experience and mood.

Some electromagnetic diaphragm pumps are structured to suck and spray liquid through two V-shaped one-way check valves respectively, and the V-shaped one-way check valves are easy to be adhered, so that the liquid sucking and spraying amount is unstable, gradually becomes smaller, and even does not discharge liquid; the long-time liquid shortage leads to the surface temperature rise of the pump body, and the defects of directly influencing the service life of the product and the like exist.

Disclosure of Invention

The invention aims to solve the technical problem that an electromagnetic diaphragm pump is scientifically designed, and the phenomenon that the amount of liquid pumped out is reduced or the liquid cannot be discharged after the electromagnetic diaphragm pump is placed for a long time is thoroughly avoided by adopting an innovative design to change two traditional V-shaped one-way check valves into a strip-shaped liquid inlet and outlet control diaphragm sheet with double one-way check valves; the traditional cylindrical liquid storage bin is changed into a hemispherical liquid storage bin, so that the reciprocating thrust of the electromagnetic force of a pump coil and a pump core is convenient to be uniform, and the problems of high surface temperature of a pump body, unstable liquid outlet flow, large deviation and the like are effectively solved, so that the surface temperature of the pump body is reduced, and the liquid outlet flow is stabilized; embodies the novelty, creativity and practicality of the electromagnetic diaphragm pump.

The technical scheme adopted by the invention for solving the technical problems is as follows: an electromagnetic diaphragm pump comprises a pump body and an electromagnet;

The pump body is integrally arranged in a T shape and comprises an outer pump sleeve and an inner pump sleeve, and the outer pump sleeve and the inner pump sleeve can be tightly combined and separated;

A pair of liquid inlet and outlet pipes are fixedly arranged at the left end of the outer pump sleeve and comprise a liquid inlet pipe and a liquid outlet pipe;

a pump seat is movably arranged in a cavity formed by tightly combining the outer pump sleeve and the inner pump sleeve, the outer pump sleeve and the pump seat are tightly combined to form a one-way valve cavity, the upper part of the one-way valve cavity is formed by communicating an E-shaped cavity slightly concave to the right and a reverse E-shaped cavity slightly concave to the left, a strip-shaped one-way valve diaphragm is movably arranged in the one-way valve cavity, the thickness of the one-way valve diaphragm is smaller than that of the one-way valve cavity, and the one-way valve diaphragm can move left and right in the one-way valve cavity; the right end of the pump seat is provided with a small semi-sphere concave cavity and is communicated with the cavity of the one-way valve through an upper channel and a lower channel;

The inner pump sleeve is arranged into a Y-shaped pipeline, an elastic diaphragm is movably arranged in an opening at the left end of the inner pump sleeve, and the left part of the elastic diaphragm is tightly combined with the small hemispheroid concave cavity at the right end of the pump base to form a liquid storage bin; the right end of the elastic diaphragm is fixedly clamped with the left end of a metal round core movably arranged in the inner pump sleeve, the right end of the metal round core is movably connected with a spring, the right end of the spring is internally connected with the rightmost end of the inner pump sleeve, and the right part of the metal round core is provided with a circle of O-shaped sealing ring;

An electromagnet is movably sleeved on the periphery of the right part of the inner pump sleeve and is fixed by a magnet protector which is movably arranged on the outer side of the right end of the inner pump sleeve; the whole electromagnet is set to be in a circular tube shape, the electromagnet comprises a coil framework and a coil fixedly arranged in the coil framework, and a pair of power supply plug terminals and the coil communicated power supply are fixedly arranged outside the electromagnet.

and the pipe orifice at the rightmost end of the liquid inlet pipe is communicated with the upper part of the cavity of the one-way valve.

and two through holes are respectively arranged at corresponding positions of the upper part and the lower part of the diaphragm of the one-way valve.

The technical characteristics and the working principle are as follows:

when the pair of power supply plug terminals is connected with a power supply, the coil in the electromagnet generates electromagnetism, and magnetic force drives the metal round core to move rightwards to press the spring to contract; the middle part of the elastic diaphragm at the left end of the metal round core also becomes concave along with the rightward displacement, so that the volume of the liquid storage bin is increased, the pressure in the liquid storage bin is reduced, and the diaphragm of the one-way valve is attracted to displace from the left side to the right side of the cavity of the one-way valve; at the moment, the upper part of the one-way valve diaphragm is separated from the pipe orifice at the rightmost end of the liquid inlet pipe to form a cavity, (meanwhile, the lower part of the one-way valve diaphragm is tightly combined with the lower channel to form a closed circuit), and the liquid in the liquid inlet pipe is sucked into the one-way valve cavity and flows into the liquid storage bin through the two through holes and the upper channel to finish the liquid suction operation.

After the frequency of the power supply is changed, the directions of electromagnetism generated by the coils in the electromagnet are opposite, magnetic force drives the metal round core to move leftwards, the spring pressed to contract rebounds, the middle part of the elastic diaphragm at the left end of the metal round core can also become convex along with the leftward movement, so that the volume of the liquid storage bin is reduced, the pressure in the liquid storage bin is increased, and the diaphragm sheet of the one-way valve is pressed to move leftwards from the right side of the cavity of the one-way valve; at the moment, the upper part of the one-way valve diaphragm is tightly combined with the pipe orifice at the rightmost end of the liquid inlet pipe to form a closed circuit, (meanwhile, the lower part of the one-way valve diaphragm is separated from the lower channel to form a cavity), and liquid in the liquid storage bin passes through the lower channel and the two through holes to flow into the liquid outlet pipe to complete liquid spraying operation.

the operation is repeated in cycles to form complete and uniform suction and spraying work.
