Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic pumps, and more particularly to an electromagnetic pump with a magnetization structure. Background Art

[0002] An electromagnetic pump is a pump device that uses electromagnetic force to move a fluid through a magnetic field. Specifically, the interaction between the magnetic field and the current in the conductive fluid creates a pressure gradient under the electromagnetic force, which propels the fluid into motion.

[0003] An electromagnetic pump typically consists of an electromagnetic coil, an iron core, a valve, and a pump body. When the electromagnetic coil is energized, it generates a magnetic field, which attracts or repels the iron core, causing the valve to open or close. This creates a space within the pump body with varying volume, allowing liquid to flow in and out of this space as the valve opens or closes. When the valve is open, liquid is drawn in; when it is closed, liquid is pushed out.

[0004] The existing electromagnetic pump valve coil will generate a large instantaneous current at the moment of power-on, resulting in poor magnetic field collection ability. In addition, the existing electromagnetic pump is a pure solenoid coil that uses a large amount of enameled wire. During operation, the coil generates a magnetic field, and the external retaining frame and magnetic yoke ring form a magnetic circuit. This method has low magnetic field utilization efficiency and high temperature rise. If the temperature rise is to be reduced, the amount of wire used can be increased, but this will lead to increased production costs; or by adding a static iron core in the cylindrical tube to improve the electromagnetic attraction and utilization efficiency, but this method will also increase production costs. During operation, the static iron core and the moving iron core will attract each other and collide, which can easily destroy the protective layer of both, causing rust and contamination of the medium.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] Please refer to Figures 1-6The utility model proposes an electromagnetic pump with a magnetizing structure, comprising a coil assembly 1 and a pump assembly 2; wherein the coil assembly 1 comprises a frame 12, a magnetizing component 13, a yoke ring 14 and several sections of coil 11, the magnetizing component 13 divides the coil 11 into several sections and is alternately arranged on the frame 12; the magnetizing component 13 is arranged on the frame 12, the yoke ring 14 is sleeved on the frame 12, and forms a closed-loop magnetic field with the frame 12; the magnetizing component 13 is used to enhance the closed-loop magnetic field; the pump assembly 2 is arranged in the frame 12; the pump assembly 2 comprises a pipe body 21, a moving component 22, a reset component 23, a sealing component 24, a valve core 25 and a water outlet pipe 26; the pipe body 21 is arranged on the frame 12; the moving component 22, the reset component 23 and the valve core 25 are movably arranged in the pipe body 21; the reset component 23 is in contact with the moving component 22; the moving component 22 is detachably connected to the valve core 25; the outlet pipe 26 is provided on one side of the tube body 21; the sealing component 24 is provided between the tube body 21 and the outlet pipe 26; the sealing component 24 includes a sealing rubber head 241, and the sealing rubber head 241 is provided at the end of the valve core 25; the moving component 22, the sealing component 24, the valve core 25 and the outlet pipe 26 form a sealed cavity 200 in the tube body 21. When the coil 11 is energized, the moving component 22 is subjected to the magnetic force of the magnetic yoke ring 14 and the magnetizing component 13, and squeezes the reset component 23 in the tube body 21. At this time, the pressure in the cavity 200 decreases, thereby opening the valve core 25; when the alternating current reaches the second half cycle, the reset component 23 is reset. At this time, the pressure in the cavity 200 increases to open the sealing rubber head 241 and reciprocate to pump water; during this period, the magnetizing component 13 enhances the magnetic force of the magnetic yoke ring 14.

[0032] In this embodiment, the coil assembly 1 and the pump assembly 2 are detachably connected or fixedly connected; specifically, the frame 12 includes a retaining frame 122 and a skeleton 123, the retaining frame 122 is sleeved on the outside of the skeleton 123, and the coil 11 is sleeved on the skeleton 123; the retaining frame 122 and the skeleton 123 are respectively provided with through holes, and the tube 21 in the pump assembly 2 passes through the through holes of the retaining frame 122 and the skeleton 123; in a specific embodiment, a connector 124 is provided on one side of the frame 12, and the connector 124 and The retainer 122 is provided with threaded holes. After aligning the through-holes of the retainer 122 with the through-holes of the frame 123, the tube 21 is inserted, and then the connector 124 is inserted into the tube 21. Screws are then screwed into the threaded holes of the connector 124 and the retainer 122 in sequence. In another embodiment, the connector 124 and retainer 122 each have two threaded holes, arranged diagonally. Only two screws are required to assemble and secure the pump assembly 2 and coil assembly 1. In another embodiment, the coil assembly 1 and pump assembly 2 are detachably connected, i.e., the pump assembly 2 is inserted into the through-holes of the retainer 122 and the frame 123. When parts need to be replaced, the pump assembly 2 is withdrawn and replaced.

[0033] The coil assembly 1 also includes a magnetizer 13, a magnetic yoke 14, and several coil segments 11. The coil 11 comprises multiple segments, which are mounted on the frame 123 along with the magnetizer 13. The multiple segments 11 are electrically connected. Compared to mounting a full coil segment on the frame 123, this arrangement saves costs and reduces the amount of enameled wire used. In one embodiment, the magnetizer 13 divides the coil 11 into two segments and is positioned in the middle of the coil 11. This eliminates the need for a coil 11 at the location of the magnetizer 13, and the magnetizer 13 provides a strong magnetic force, working together with the magnetic yoke 14 to magnetically attract the movable assembly 22, enabling horizontal movement within the tube 21. The coil 11 and the magnetic yoke ring 14 are respectively arranged on the skeleton 123, and the retaining frame 122 is arranged on the outside of the skeleton 123; when the electromagnetic pump is working, the coil 11 will generate a magnetic field after being energized, and the external magnetic field is magnetized through the retaining frame 122. The magnetic yoke ring 14 magnetizes the internal magnetic field and works together with the retaining frame 122 to form a closed loop of the magnetic field; in a specific embodiment, the magnetic yoke ring 14 includes an upper magnetic yoke ring 141 and a lower magnetic yoke ring 142. The setting positions of the upper magnetic yoke ring 141 and the lower magnetic yoke ring 142 are limited by the placement holes provided in the skeleton 123. The upper magnetic yoke ring 141 and the lower magnetic yoke ring 142 magnetize the internal magnetic field and work together with the retaining frame 122 to form a closed loop of the magnetic field.

[0034] The retaining frame 122, the magnetic yoke ring 14 and the magnetizing component 13 are provided as magnetic conductors; the magnetizing component is provided for increasing the magnetic force. In a specific embodiment, the magnetizing component 13 is a magnet and has magnetism; the magnetizing component 13 is distributed in a ring shape on the frame 12; in a specific embodiment, there are four magnetizing components 13, and they are distributed in a ring shape on the outside of the frame 12; in another specific embodiment, the magnetizing component 13 is a sheet body, which is installed on the skeleton 123 and divides the coil 11 into two parts; in another specific implementation, the magnetizing component 13 is cylindrical and is provided on the skeleton 123.

[0035] Specifically, the position of the magnetizing component 13 can be set according to the use requirements of the electromagnetic pump. When an electromagnetic pump with higher pressure and flow is required, the magnetizing component 13 is set near the lower magnetic yoke ring 142 to increase the magnetic force around the lower magnetic yoke ring 142 to obtain higher pressure and a larger stroke; after the water pump of the electromagnetic pump dries up, the moving component 22 will encounter greater resistance and stop moving. At this time, the magnetizing component 13 is placed in the middle position between the upper magnetic yoke ring 141 and the lower magnetic yoke ring 142, so that the initial electromagnetic force is enhanced and overcomes the resistance to move.

[0036] During operation, the coil 11 is energized. At this time, the magnetic yoke ring 14 and the magnetizing component 13 will jointly generate a magnetic field, which will be transmitted to the moving component 22. At this time, the magnetizing component 13 strengthens the magnetic force generated by the magnetic flux inside the coil 11. The moving component 22 moves to the left under the action of the magnetic yoke ring 14. At the same time, the volume of the sealed cavity 200 formed by the moving component 22, the sealing component 24, the valve core 25 and the outlet pipe 26 in the tube body 21 increases, and the pressure decreases. At this time, the valve core 25 is passively opened to balance the pressure in the cavity 200. The current used is alternating current, and half a cycle of current will remain after the current passes through the provided diode. Therefore, when the electromagnetic pump is powered on and off, the reset component 23 is reset after compression and deformation, and pushes out the moving component 22, causing the moving component 22 to move to the right. At the same time, the volume of the cavity 200 decreases and the pressure increases, causing the sealing rubber head 241 to open to balance the pressure, and work reciprocatingly to pump water. In one embodiment, the coil assembly 1 is externally connected to a current regulating module to adjust the coil current and reduce energy waste. In another embodiment, the coil assembly 1 is externally connected to a control module and a display screen to allow the operator to control and monitor the working status of the electromagnetic pump, thereby improving work efficiency and reducing damage to the electromagnetic pump caused by operational errors.

[0037] The utility model is capable of dividing the enameled wire of the coil 11 into multiple parts by arranging a magnetizing component 13 on the frame 12. When the coil 11 is energized, the magnetizing component 13 will hinder the instantaneous current of the multiple parts, and the induced current transmitted to the magnetizing component 13 will be offset accordingly, so as to reduce the instantaneous current. Since the magnetizing component 13 is magnetic, the magnetic field around the magnetizing component 13 will be enhanced. When energized, the magnetic force exerted on the moving component 22 will be enhanced, and it will reciprocate in the tube body 21, so as to pump water. The provision of the magnetizing component 13 can not only increase the electromagnetic attraction, but also greatly reduce the use of enameled wire, reduce costs, reduce power and increase efficiency.

When the coil 11 is energized, a magnetic field is generated, and the external magnetic field is magnetized through the retaining frame 122. The upper magnetic yoke ring 141 and the lower magnetic yoke ring 142 magnetize the internal magnetic field, and work together with the retaining frame 122 to form a closed loop of the magnetic field. During this period, the magnetizing component 13 can increase the magnetic force.

[0040] Specifically, the magnetizing component 13 is arranged on the skeleton 123. When an electromagnetic pump with higher pressure and flow is required, the magnetizing component 13 is arranged near the lower magnetic yoke ring 142 to increase the magnetic force around the lower magnetic yoke ring 142 to obtain higher pressure and a larger stroke; after the water pump of the electromagnetic pump dries up, the moving component 22 will encounter greater resistance and stop moving. At this time, the magnetizing component 13 is placed in the middle position between the upper magnetic yoke ring 141 and the lower magnetic yoke ring 142, so that the initial electromagnetic force is enhanced and the resistance is overcome to move.

Specifically, after the coil 11 is energized, the iron core 221 moves to the left under the magnetic force of the magnetic yoke ring 14 and the magnetizing member 13. At the same time, the volume of the sealed cavity 200 formed by the moving assembly 22, the sealing assembly 24, the valve core 25 and the outlet pipe 26 in the tube body 21 increases and the pressure decreases. At this time, the valve core 25 is passively opened to balance the pressure in the cavity 200; in the next cycle of the current, the first elastic member 231 is reset, causing the iron core 221 to move to the right. At the same time, the volume of the cavity 200 decreases and the pressure increases, causing the sealing rubber head 241 to open to pump out the liquid. The first elastic member 231 and the second elastic member 232 are arranged in the tube body 21 and on both sides of the iron core 221; the second elastic member 232 can form a buffer for the iron core 221; after the coil 11 is energized, the magnetic yoke ring 14 generates magnetic force, and moves in the tube body 21 under the action of the magnetic force; when the iron core 221 moves to the left, pressure is applied to the first elastic member 231, and the first elastic member 231 is compressed and deformed after being subjected to the force; then the first elastic member 231 is reset, and the iron core 221 moves to the right, squeezing the second elastic member 232.

[0058] Please refer to Figure 9 and Figure 10 , Figure 9 The coil is not equipped with a magnetizing component, and the coil wire diameter is 0.23mm and the weight is 150g. As can be seen from the figure, the temperature rise of the coil is 141.64547619 at this time. Figure 10The coil is equipped with a magnetizer, and the coil wire diameter is 0.18mm and weighs 80g. As shown in the figure, the coil temperature rise is 84.59421488. In summary, after adding the magnetizer 13 to the coil 11, the temperature rise of the coil 11 is much lower than that without the magnetizer 13, and the flow rate change rate is small, which is more stable. This shows that the magnetizer 13 has strong thermal conductivity, which can transfer heat from the inside of the coil 11 to the outside, reducing the temperature rise. At the same time, the weight of the enameled wire used is relatively low, which can greatly reduce costs.
