Description

Technical Field

[0001] The invention relates to the field of micro pumps, in particular to an electromagnetic diaphragm pump. Background Art

[0002] The noise generated by the traditional liquid pump motor when it rotates is a shortcoming that users hate very much and directly affects the user's experience and mood.

[0003] Some electromagnetic diaphragm pumps are structured to suck and spray liquids through two V-shaped one-way check valves respectively. The V-shaped one-way check valves are prone to adhesion, resulting in unstable suction and spraying liquid volume, which gradually decreases or even no liquid is discharged. Long-term lack of liquid causes the surface temperature of the pump body to rise, which directly affects the product life. Summary of the invention

[0004] The technical problem to be solved by the present invention is to scientifically design an electromagnetic diaphragm pump. Through innovative design, the traditional two V-shaped one-way check valves are replaced with an elongated double one-way check valve to control the inlet and outlet liquids of the diaphragm, so as to completely avoid the phenomenon that the amount of pumped liquid becomes smaller or no liquid is discharged after long-term storage; the traditional cylindrical liquid storage tank is replaced with a hemispherical liquid storage tank, so as to facilitate the uniform constant pump coil electromagnetic force and the thrust of the pump core reciprocating movement, and effectively solve the problems of high pump body surface temperature, unstable liquid flow rate, large deviation, etc., thereby reducing the pump body surface temperature and stabilizing the pumped liquid flow rate; reflecting the innovation, creativity and practicality of the electromagnetic diaphragm pump.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an electromagnetic diaphragm pump, comprising a pump body and an electromagnet;

[0006] The pump body is configured as a "T" shape as a whole, including 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;

[0007] A pair of liquid inlet and outlet pipes are fixedly arranged at the left end of the outer pump sleeve, and the pair of liquid inlet and outlet pipes include a liquid inlet pipe and a liquid outlet pipe;

[0008] A pump seat is movably arranged in a cavity formed by the close combination of the outer pump sleeve and the inner pump sleeve, and the outer pump sleeve and the pump seat are closely combined to form a one-way valve cavity, the upper part of the one-way valve cavity is composed of an "E"-shaped cavity slightly concave to the right and a lower part is connected by an inverted "E"-shaped cavity slightly concave to the left, and a long strip of one-way valve diaphragm is movably arranged in the one-way valve cavity, the thickness of the one-way valve diaphragm is smaller than the one-way valve cavity, and it can move left and right in the one-way valve cavity; the right end of the pump seat is set as a small hemispherical concave cavity, and is connected to the one-way valve cavity through an upper channel and a lower channel;

[0009] The inner pump sleeve is configured as a "Y"-shaped pipe, an elastic diaphragm is movably arranged in the opening at the left end of the inner pump sleeve, and the left part of the elastic diaphragm is tightly combined with the small hemispherical concave cavity at the right end of the pump seat to form a liquid storage tank; the right end of the elastic diaphragm is clamped and fixed with the left end of the metal round core movably arranged in the inner pump sleeve, the right end of the metal round core is movably connected to a spring, the right end of the spring is connected to the rightmost end of the inner pump sleeve, and a circle of O-shaped sealing ring is arranged on the right part of the metal round core;

[0010] An electromagnet is movably mounted on the outer periphery of the right part of the inner pump sleeve and is fixed by a retaining magnet movably arranged on the outer side of the right end of the inner pump sleeve; the electromagnet is arranged in a circular tube shape as a whole, and the electromagnet includes a coil frame and a coil fixedly arranged in the coil frame, and a pair of power plug terminals are fixedly arranged on the outside of the electromagnet to connect the coil to a power source.

[0011] The rightmost pipe opening of the liquid inlet pipe is communicated with the upper part of the one-way valve cavity.

[0012] The rightmost pipe opening of the liquid outlet pipe is communicated with the lower part of the one-way valve cavity.

[0013] Two through holes are respectively arranged at corresponding positions of the upper and lower parts of the one-way valve diaphragm.

[0014] Technical features and working principles:

[0015] When the pair of power connectors are connected to a power source, the coil in the electromagnet generates an electromagnetic force, and the magnetic force drives the metal core to move to the right to compress the spring to contract; the middle part of the elastic diaphragm at the left end of the metal core will also become concave as it moves to the right, so that the volume of the liquid storage tank becomes larger, and the pressure in the liquid storage tank becomes smaller, attracting the one-way valve diaphragm to move from the left side of the one-way valve cavity to the right side; at this time, the upper part of the one-way valve diaphragm is separated from the pipe mouth at the rightmost end of the liquid inlet pipe to form a cavity (at the same time, 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 tank through the two transparent holes and the upper channel to complete the liquid suction operation.

[0016] When the power supply frequency is changed, the electromagnetic direction generated by the coil in the electromagnet is opposite, the magnetic force drives the metal core to move to the left, the compressed and contracted spring rebounds, and the middle part of the elastic diaphragm at the left end of the metal core becomes convex as it moves to the left, so that the volume of the liquid storage tank becomes smaller, the pressure in the liquid storage tank becomes larger, and the one-way valve diaphragm is pressed to move from the right side of the one-way valve cavity to the left side; at this time, the upper part of the one-way valve diaphragm is tightly combined with the pipe mouth at the rightmost end of the liquid inlet pipe to form a closed circuit (at the same time, the lower part of the one-way valve diaphragm is separated from the lower channel to form a cavity), and the liquid in the liquid storage tank passes through the lower channel and the two transparent holes and flows into the liquid outlet pipe to complete the liquid spraying operation.

[0017] This cycle repeats itself over and over again, forming a complete and uniform suction and spraying process.

The outer pump sleeve 13 and the pump seat 6 are closely combined to form a one-way valve cavity 18. The upper part of the one-way valve cavity 18 is connected by an "E"-shaped cavity 18a slightly concave to the right and a lower part is connected by an inverted "E"-shaped cavity 18b slightly concave to the left. A long strip of one-way valve diaphragm 5 is movably arranged in the one-way valve cavity 18. The thickness of the one-way valve diaphragm 5 is smaller than that of the one-way valve cavity 18, and it can move left and right in the one-way valve cavity 18; the right end of the pump seat 6 is set as a small hemispherical concave cavity, and is connected to the one-way valve cavity 18 through an upper channel 17a and a lower channel 17b;

[0032] The inner pump sleeve 15 is configured as a "Y"-shaped pipeline, an elastic diaphragm 7 is movably arranged in the opening at the left end of the inner pump sleeve 15, and the left part of the elastic diaphragm 7 is tightly combined with the small hemispherical concave cavity at the right end of the pump seat 6 to form a liquid storage tank 14; the right end of the elastic diaphragm 7 is clamped and fixed with the left end of the metal round core 8 movably arranged in the inner pump sleeve 15, and the right end of the metal round core 8 is movably connected to a spring 10, and the right end of the spring 10 is connected to the rightmost end of the inner pump sleeve 15. A circle of O-ring 9 is arranged on the right part of the metal round core 8;

[0033] An electromagnet 2 is movably mounted on the outer periphery of the right part of the inner pump sleeve 15 and is fixed by a magnetizing body 16 movably arranged on the outer side of the right end of the inner pump sleeve 15; the electromagnet 2 is configured as a circular tube as a whole, and the electromagnet 2 includes a coil frame 12 and a coil 11 fixedly arranged in the coil frame 12, and a pair of power connector terminals 4a, 4b are fixedly arranged on the outside of the electromagnet 2 to connect the coil 11 to power.

[0037] Technical features and working principles:

[0038] When the pair of power connectors 4a, 4b are connected to a power source, the coil 11 in the electromagnet 2 generates an electromagnetic force, and the magnetic force drives the metal core 8 to move rightward to compress the spring 10 to contract; the middle part of the elastic diaphragm 7 at the left end of the metal core 8 will also become concave as it moves rightward, so that the volume of the liquid storage bin 14 becomes larger, and the pressure in the liquid storage bin 14 becomes smaller, attracting the one-way valve diaphragm 5 to move from the left side of the one-way valve cavity 18 to the right side; at this time, the upper part of the one-way valve diaphragm 5 is separated from the pipe opening 3aa at the rightmost end of the liquid inlet pipe 3a to form a cavity (at the same time, the lower part of the one-way valve diaphragm 5 is tightly combined with the lower channel 17b to form a closed circuit), and the liquid in the liquid inlet pipe 3a is sucked into the one-way valve cavity 18, and flows into the liquid storage bin 14 through the two transparent holes 5a and the upper channel 17a, completing the liquid suction operation 19.

[0039] When the power supply frequency is changed, the electromagnetic direction generated by the coil 11 in the electromagnet 2 is opposite, and the magnetic force drives the metal core 8 to move to the left, and the compressed and contracted spring 10 rebounds. The middle part of the elastic diaphragm 7 at the left end of the metal core 8 will also become convex as it moves to the left, so that the volume of the liquid storage tank 14 becomes smaller, and the pressure in the liquid storage tank 14 becomes larger, forcing the one-way valve diaphragm 5 to move from the right side of the one-way valve cavity 18 to the left side; at this time, the upper part of the one-way valve diaphragm 5 is tightly combined with the pipe opening 3aa at the rightmost end of the liquid inlet pipe 3a to form a closed circuit (at the same time, the lower part of the one-way valve diaphragm 5 is separated from the lower channel 17b to form a cavity), and the liquid in the liquid storage tank 14 passes through the lower channel 17b and the two transparent holes 5b and flows into the liquid outlet pipe 3b to complete the liquid spraying operation 19.

[0040] This cycle repeats itself over and over again, forming a complete and uniform suction and spraying process.

[0041] Compared with the prior art, the advantages of the present invention are:

[0042] The electromagnetic diaphragm pump of the present invention adopts an elongated double one-way check valve as the liquid inlet and outlet control diaphragm through innovative design, which completely avoids the phenomenon that the amount of pumped liquid becomes smaller or no liquid is discharged after long-term storage; the traditional cylindrical liquid storage bin is changed into a hemispherical liquid storage bin, which is convenient for balancing the electromagnetic force of the constant pump coil and the thrust of the reciprocating movement of the pump core, and effectively solves the problems of high surface temperature of the pump body, unstable liquid flow rate, large deviation, etc., thereby reducing the surface temperature of the pump body and stabilizing the beneficial effect of pumping liquid flow rate; it embodies the innovation, creativity and practicality of the electromagnetic diaphragm pump, and will surely be loved by professionals and the market.
