Description
Technical Field
The invention relates to the technical field of electromagnetic pumps, in particular to an electromagnetic pump with high stability.
Background
An electromagnetic pump is a pump which pushes a piston to reciprocate under the action of electromagnetic force so as to enable fluid to flow in a certain direction. The electromagnetic pump uses alternating current as working power, and the current forms alternating magnetic field through electromagnetic winding, forms the interact with the movable pump body, drives the pump body vibration, promotes liquid output.
Fig. 1 is a schematic structural diagram of a water outlet structure 10 of a conventional electromagnetic pump. The water outlet structure 10 comprises a water outlet 11, a water outlet check valve 12, a telescopic spring 13 and a water outlet pipeline 14. The water outlet 11 is arranged at the joint of the water inlet pipeline 15 and the water outlet pipeline 14. The inlet conduit 15 communicates with the outlet conduit 14. The water outlet check valve 12 and the expansion spring 13 are arranged in the water outlet pipeline 14. The extension spring 13 provides an elastic force to the outlet check valve 12 in a direction approaching the outlet 11, so that the outlet check valve 12 is contacted with or separated from the outlet 11 by the impact force of the water flow and the elastic force of the extension spring 13. In the water inlet state, the pressure in the water inlet pipeline 15 is negative, and the water outlet check valve 12 is in contact with the water outlet 11. In the water outlet state, the water flow in the water inlet pipe 15 is flushed toward the water outlet check valve 12, so that the water outlet check valve 12 is separated from the water outlet 11, and at the same time, the water in the water inlet pipe 15 enters the water outlet pipe 14.
However, in the conventional electromagnetic pump 10 shown in fig. 1, the outlet check valve 12 has a hemispherical structure. In the water inlet state, the water outlet check valve 2 collides with the water outlet 11 under the elastic force action of the expansion spring 13. In the repeated water inlet and outlet process of the electromagnetic pump 10, the water outlet check valve 12 repeatedly collides with the water outlet 11 under the elastic force action of the expansion spring 13. The water outlet check valve 12 of the conventional electromagnetic pump 10 is a rigid plastic part, which is easily damaged during repeated impact, and thus the air tightness of the water inlet pipe 15 during water inlet is affected, so that the electromagnetic pump cannot pump water normally.
In addition, in the conventional solenoid pump 10 shown in fig. 1, in the water discharge state, the water flow in the water inlet pipe 15 impacts the water discharge non-return valve 12 and causes the extension spring 13 to contract. However, the impact force of the water flow against the outlet check valve 12 is not completely uniform, and the span of the extension spring 13 is large, so that the extension spring 13 is twisted and biased by the impact of the water flow, rather than telescopically moving in a straight line. The torsion and the offset of the expansion spring 13 further cause that the expansion spring 13 cannot accurately reset when resetting towards the water outlet 11, that is, the water outlet check valve 12 cannot accurately contact with the water outlet 11 when moving towards the water outlet 11 under the elastic force of the expansion spring 13. The water outlet check valve 12 cannot be accurately contacted with the water outlet 11, so that the water inlet pipeline 15 cannot be completely sealed during water inlet, normal water inlet is affected, and finally the electromagnetic pump 10 is abnormal in operation.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
As shown in fig. 1, it is a water outlet structure 10 of a conventional electromagnetic pump. The span of the expansion spring 13 of the water outlet structure 10 of the conventional electromagnetic pump is large, so that the expansion spring 13 is easy to twist and deflect under water flow impact, and further the expansion spring 13 cannot accurately reset when being reset towards the direction of the water outlet 11. The water outlet check valve 12 cannot accurately contact the water outlet 11 when moving towards the water outlet 11 under the elastic force action of the extension spring 13, so that the water inlet pipeline 15 cannot be completely sealed when water enters, the normal water inlet of the traditional electromagnetic pump is influenced, and finally the electromagnetic pump 10 is caused to work abnormally. In order to solve the technical problems of the water outlet structure 10 of the conventional electromagnetic pump, the present invention proposes the following solutions:
as shown in fig. 2, a high-stability electromagnetic pump 20 includes an electromagnetic pump body 30 and a water outlet check valve device 40. The electromagnetic pump body 30 has a fluid passing chamber 310, and the outlet check valve device 40 is accommodated in the fluid passing chamber 310.
The following describes a specific structure of the outlet check valve device 40 and a connection relationship between the respective members:
as shown in fig. 3, the outlet check valve device 40 includes: the fixing member 410, the guide post 420, the sliding member 430, the return elastic member 440, and the sealing member 450.
As shown in fig. 2, a fixing member 410 is fixed in the fluid passing chamber 310, and a guide post 420 is provided on the fixing member 410. That is, the guide post 420 is fixed in the fluid passing chamber 310 by the fixing member 410. In the present embodiment, the fixing member 410 is a cylinder structure. Of course, in other embodiments, the fixing member 410 is a plate structure with a through hole.
As shown in fig. 3, the sliding assembly 430 includes: collar 431, link 432 and movable plate 433. The lantern ring 431 is slidably sleeved on the guide column 420, and the lantern ring 431 is connected with the movable plate 433 through a connecting rod 432. The preferred mode is as follows: the number of the links 432 is plural, and the plural links 432 are distributed in a circular array around the central axis of the guide column 420. Further preferred is: the number of the links 432 is three.
Compared with the embodiment in which the collar 431 is connected to the movable plate 433 through the connecting rod 432, the former embodiment causes the sliding assembly 430 to have much smaller resistance to water when sliding back and forth on the guide post 420 than the latter embodiment in which the collar 431 is connected to the movable plate 433 through the sleeve. The lantern ring 431 is connected with the movable plate 433 through the connecting rods 432, so that the connecting rods 432 are distributed in an annular array to form an annular cavity in a hollow shape. In the embodiment in which the number of the connecting rods 432 is three, on one hand, the resistance of the sliding assembly 430 to water when sliding back and forth on the guide post 420 is further reduced, and on the other hand, the material is saved.
As shown in fig. 3, the elastic restoring member 440 is disposed between the fixed member 410 and the movable plate 433, and the sealing member 450 is disposed on the movable plate 433. Specifically, one end of the elastic restoring member 440 is connected to the fixing member 410, and the other end is connected to the movable plate 433. In this embodiment, the return elastic member 440 has a spring structure. Of course, in the present embodiment, the return elastic member 440 may adopt a cylindrical spring structure.
As shown in fig. 2, a check valve stop ring 311 is disposed in the fluid passage chamber 310, and the return elastic member 440 is used for providing an elastic force to the movable plate 433, so that the sealing assembly 450 has a tendency to press against the check valve stop ring 311.
In this embodiment, the fixing member 410 is fixed in the fluid passing chamber 310, and the guide post 420 is provided on the fixing member 410. Meanwhile, the ring 431 is slidably sleeved on the guide post 420, and the ring 431 is connected with the movable plate 433 through a connecting rod 432.
The electromagnetic pump 20 with high stability is in the process of water outlet: the water flows through check valve blocker ring 311 from the side away from seal assembly 450 and then impacts seal assembly 450 and separates seal assembly 450 from check valve blocker ring 311. Due to the guiding action of the guide post 420 on the sliding assembly 430, the sliding assembly 430 moves linearly in a direction away from the check valve blocker ring 311 without twisting or shifting.
Similarly, the electromagnetic pump 20 with high stability is used for the water inlet process: during the resetting process of the sealing assembly 450, due to the guiding effect of the guiding column 420 on the sliding assembly 430, the sliding assembly 430 moves linearly in the direction approaching to the check valve stop ring 311 and is accurately reset to be pressed against the check valve stop ring 311 without twisting or shifting.
In addition, the lantern ring 431 is sleeved on the guide post 420 in a sliding mode, so that the stability and the reliability of the reset elastic piece 440 are improved, and the stability and the reliability of the electromagnetic pump 20 with high stability are further improved.
As shown in fig. 1, it is a water outlet structure 10 of a conventional electromagnetic pump. The water outlet check valve 12 of the conventional electromagnetic pump 10 is a rigid plastic part which is easily damaged in a repeated impact process, and further influences the air tightness of the water inlet pipeline 15 during water inlet, so that the electromagnetic pump cannot pump water normally. Although the material cost for replacing the outlet check valve 12 is low, replacing parts requires the electromagnetic pump to be suspended for a certain time, which affects the productivity of the electromagnetic pump. Therefore, the loss of the outlet check valve 12 of the electromagnetic pump leads to an increase in the production time cost, and thus the productivity of the electromagnetic pump is lowered.
In order to solve the technical problems of the water outlet structure 10 of the conventional electromagnetic pump, the present invention proposes the following solutions:
as shown in fig. 3, the sealing assembly 450 includes: a gasket 451, a strain transmission post 452, and a cushion elastic member 453.
As shown in fig. 3 and 4, in the present embodiment, the deformation conductive pillar 452 has a truncated cone structure, and the deformation conductive pillar 452 has a wide cross-section end 454 and a narrow cross-section end 455. The wide cross-sectional end 454 of the deformation-transmitting pillar is connected to the sealing gasket 451, and the narrow cross-sectional end 455 of the deformation-transmitting pillar is connected to the movable plate 433.
As shown in fig. 3 and 6, the buffer elastic member 453 is compressed between the sealing gasket 451 and the movable plate 433. In this embodiment, the cushion spring 451 is a tower-shaped spring structure having a wide cross-sectional end 456 and a narrow cross-sectional end 457. The wide cross-sectional end 456 of the cushion spring is connected to the sealing gasket 451, and the narrow cross-sectional end 457 of the cushion spring is connected to the movable plate 433.
As shown in fig. 2, the sealing gasket 451 is pressed against the check valve blocking ring 311 or separated from the check valve blocking ring 311. In this embodiment, the sealing gasket 451 is a flexible rubber gasket.
In this embodiment, the elastic force provided by the elastic return member 440 to the sealing gasket 451 is buffered by the deformation of the deformation-transmitting post 452 itself. Further, in the present embodiment, the buffering elastic member 453 has a tower-shaped spring structure, the wide cross-sectional end 456 of the buffering elastic member is connected to the sealing gasket 451, and the narrow cross-sectional end 457 of the buffering elastic member is connected to the movable plate 433. The sealing gasket 451 is a flexible rubber gasket. Through such structural design, have following beneficial effect: the elastic force of the return elastic member 440 is buffered by the deformation of the deformation transmitting post 452 itself, the deformation of the buffering elastic member 453, and the deformation of the flexible rubber pad 451. The elastic force of the return elastic member 440 is buffered, so that the sealing gasket 451 is slowly pressed against the check valve stopper ring 311 instead of rigidly hitting against the check valve stopper ring 311 in the process of being pressed against the check valve stopper ring 311. The sealing gasket 451 is slowly pressed on the check valve stop ring 311, so that the situation that the sealing gasket 451 repeatedly and rigidly collides with the check valve stop ring 311 in the process of repeatedly feeding and discharging water of the high-stability electromagnetic pump 20 is effectively avoided, the service life of the sealing gasket 451 is greatly prolonged, and the part replacement times of the high-stability electromagnetic pump 20 are reduced.
It needs to be further explained that: as shown in fig. 3 and 4, in the present embodiment, the wide cross-section end 454 of the deformation-transmitting pillar is connected to the sealing gasket 451, and the narrow cross-section end 455 of the deformation-transmitting pillar is connected to the movable plate 433; the wide cross-section end 456 of the elastic buffer member is connected to the sealing gasket 451, and the narrow cross-section end 457 of the elastic buffer member is connected to the movable plate 433; the sealing gasket 451 is a flexible rubber gasket. With such a structure, the elastic force of the elastic restoring member 440 transmitted from the movable plate 433 is distributed and applied to the sealing pad 451 over a large area, and the sealing pad 451 is deformed to obtain a uniform arc surface 458. The even deformation of seal gasket 451 for the atress of seal gasket 451 and the check valve stop ring 311 contact part is also more even, effectively avoids seal gasket 451 to lead to its some local deformation too big and influence the deformability of seal gasket 451 because of the atress is inhomogeneous, or leads to seal gasket 451 to damage because of the atress is too big. Once the deformation capability of the sealing gasket 451 is reduced, the sealing performance when the sealing gasket is pressed against the check valve stop ring 311 is poor, and thus the electromagnetic pump 20 with high stability cannot normally feed and discharge water. The scheme provided in the embodiment can significantly prolong the service life of the sealing gasket 451, thereby improving the stability of the electromagnetic pump 20 with high stability.
It needs to be further explained that: as shown in fig. 6, the inner circumference of the check valve blocker ring 311 is formed with a fillet 312. Meanwhile, the sealing gasket 451 is a flexible rubber gasket. The round angle 312 of the inner ring of the check valve stop ring 311 and the sealing gasket 451 are made of flexible rubber gaskets, so that the contact part of the check valve stop ring 311 and the sealing gasket 451 is a cambered surface. When the check valve stopper ring 311 contacts the sealing gasket 451, the sealing gasket 451 is deformed. The one-way valve stop ring 311 is contacted with the sealing gasket 451 in a cambered surface contact way, so that on one hand, the sealing gasket 451 is pressed and held on the one-way valve stop ring 311 more tightly and more stably, and the sealing property is better; on the other hand, when the sealing gasket 451 is pressed on the check valve stop ring 311, the damage to the sealing gasket 451 is minimum, the service life of the sealing gasket 451 is greatly prolonged, the economic benefit of an enterprise is greatly improved, and the market competitiveness of the enterprise is remarkably improved.
The working principle of the electromagnetic pump 20 with high stability is as follows:
when the electromagnetic pump 20 with high stability is filled with water, the sliding assembly 430 is reset towards the direction close to the check valve stop ring 311 under the elastic force of the reset elastic member 440. Because the ring 431 of the sliding assembly 430 is slidably sleeved on the guide post 420, the guide post 420 provides a guiding function for the sliding assembly 430 when the sliding assembly 430 is reset towards the direction close to the check valve stop ring 311, so that the sliding assembly 430 moves linearly along the guide post 420. The sliding member 430 moves linearly along the guide post 420 until the sealing member 450 presses against the check valve stop ring 311;
when the electromagnetic pump 20 with high stability discharges water, the water flows through the check valve stop ring 311 from the side far away from the sealing assembly 450 and then rushes to the sealing assembly 450, so that the sealing assembly 450 is separated from the check valve stop ring 311. Of course, in the process of separating the sealing assembly 450 from the check valve stop ring 311, since the collar 431 of the sliding assembly 430 is slidably sleeved on the guide post 420, when the sliding assembly 430 moves away from the check valve stop ring 311, the guide post 420 provides a guiding function for the sliding assembly 430, so that the sliding assembly 430 moves linearly along the guide post 420. The water flow flows through the check valve stop ring 311 from the side away from the sealing assembly 450 and then towards the sealing assembly 450, so that the impact force of the water flow on the sealing assembly 450 is not uniform, but the guide column 420 provides a guiding function for the sliding assembly 430, thereby ensuring that the sliding assembly 430 performs a stable linear motion, and accordingly, the sealing assembly 450 also performs a stable linear motion.
The electromagnetic pump 20 with high stability provided by the invention has high stability and reliability, and the labor cost and time cost for detection and maintenance are low, so that considerable economic benefits are brought to enterprises, and the market competitiveness of the enterprises is improved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
