Description

Technical Field

[0001] This application relates to the field of electromagnetic pump technology, and in particular to induction coil structures and electromagnetic pumps, electromagnetic valves, and electromagnetic fluid pumps. Background Technology

[0002] An electromagnetic pump is a pumping device that uses an electric current-carrying fluid in a magnetic field to transport and flow liquids under the influence of electromagnetic force. Specifically, it utilizes the interaction between a magnetic field and an electric current in a conductive fluid to create a pressure gradient in the fluid due to electromagnetic force, thereby propelling 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, causing the iron core to experience attractive or repulsive forces, which in turn open or close the valve. This creates a space with changing volume inside the pump body, through which liquid flows in and out. When the valve is open, liquid is drawn in; when the valve is closed, liquid is expelled.

[0004] The electromagnetic coil in the existing electromagnetic pump generates a magnetic field when energized. The strength of the magnetic field is concentrated at the two poles, which is higher than that in the middle of the electromagnetic coil. Too many insulated wires are placed in the middle of the coil, resulting in waste, which leads to high cost, low efficiency and high temperature rise of the electromagnetic pump.

[0024] Fourthly, the present invention discloses an electromagnetic valve comprising the aforementioned induction coil structure.

[0025] Fifthly, the present invention discloses an electromagnetic fluid pump, which includes the aforementioned induction coil structure.

[0026] The technical solution provided in this application has the following advantages compared with the prior art: The induction coil structure, electromagnetic pump, electromagnetic valve, and electromagnetic fluid pump provided in this application include an induction coil structure in which a wound coil is mounted on a frame. The wound coil generates a magnetic field when energized. The wound coil is formed by winding insulating wires. The number of insulated wires at both ends of the frame is greater than the number of insulated wires in the middle. This design allows the induction coil structure to retain the insulated wires at both ends, which have a higher magnetic field strength, while reducing the number of insulated wires in the middle of the frame. This design accommodates the higher magnetic field strength at both ends of the magnetic field, thereby reducing the amount of insulated wires used in the middle of the wound coil. The induction coil structure achieves a lightweight design and low power consumption.

[0027] In addition, the induction coil structure mentions that at least two winding coils are set inside. The winding coils are set in segments. The winding density of the winding coil set in the middle of the frame is smaller than that of the winding coils set at both ends of the frame. This can reduce the number of insulated wires on the winding coil in the middle and reduce the amount of insulated wires used in the winding coil in the middle. The induction coil structure is weight-reduced and requires less power to generate the same electromagnetic force.

[0028] Furthermore, different current values ​​can be input to each winding coil, allowing the induction coil structure to apply different electromagnetic forces on the corresponding segments, thereby responding to the varying magnitudes of electromagnetic forces and enabling more precise drive control.

[0029] Furthermore, the induction coil structure is equipped with a magnetizing component, which can divide the coil's insulated wire into two parts. When the insulated wire is energized, the magnetizing component will simultaneously impede the instantaneous current in both parts, and the induced current conducted to the magnetizing component will cancel each other out. The magnetic field around the magnetizing component will be enhanced, and the magnetic force on the iron core will be enhanced when energized. The magnetizing component has strong thermal conductivity, which can quickly conduct the heat inside the coil to the outside.

[0030] Furthermore, the induction coil structure is equipped with a magnetic yoke and a cage, which can conduct magnetism from the inside and outside of the frame, respectively. This allows the direction of the magnetic field generated by the energized winding coil to follow the magnetic yoke and cage, increasing the magnetic field strength and guiding and concentrating the magnetic field lines. The magnetic fields generated by the magnetic yoke and cage are superimposed on the magnetic field of the coil itself, significantly enhancing the overall magnetic field strength. The addition of the magnetic yoke and cage strengthens the magnetic field, allowing the coil to generate a stronger electromagnetic force or induced electromotive force under the same current, thus reducing energy loss.

[0031] The electromagnetic pump, as mentioned, includes an induction coil structure and a pump assembly. The induction coil structure is located outside the pump assembly. The winding coil, magnetic yoke, and cage within the induction coil structure form a closed-loop magnetic field. When the winding coil is energized, it provides electromagnetic force to the iron core within the pump assembly, thereby driving the iron core to move. The iron core, in turn, drives the valve core to move, thus regulating the flow rate and velocity of the liquid within the electromagnetic pump. The induction coil mechanism within the electromagnetic pump reduces the number of insulated wires, lowering the overall cost of the electromagnetic pump. The induction coil structure also requires lower power consumption and reduces the temperature rise of the induction coil structure, consequently reducing the temperature rise of the electromagnetic pump.

[0032] Furthermore, the pump assembly has a cavity with a self-priming and pressurization function. By applying pressure to the fluid within the cavity, the output fluid can generate high pressure, thereby meeting the demand for high-pressure fluid output. In addition, if there is no fluid inside the electromagnetic pump, the iron core may become too dry and have high resistance, preventing it from moving. By incorporating a magnetizing element within the induction coil structure, the magnetic field strength can be enhanced, making the electromagnetic force stronger and increasing the initial electromagnetic force, thus making it easier for the iron core to overcome resistance.

[0033] Furthermore, by installing a magnetizing component on the frame, the electromagnetic pump can divide the insulated wire of the coil into multiple parts. When the coil is energized, the magnetizing component will impede the instantaneous current in multiple parts, and the induced current conducted to the magnetizing component will be correspondingly canceled, thereby reducing the instantaneous current. The magnetic field around the magnetizing component is enhanced. When energized, the magnetic force on the moving component is enhanced, and it reciprocates within the tube, thus pumping water. This not only increases the electromagnetic attraction but also greatly reduces the amount of insulated wire used, lowering costs, reducing power consumption, and improving efficiency. Moreover, the magnetizing component has strong thermal conductivity, which can conduct heat from inside the coil to the outside, reducing temperature rise.

[0034] Furthermore, existing electromagnetic pumps use pure solenoid coils with a large number of insulated wires. During operation, the coil generates a magnetic field, which forms a magnetic circuit with the external cage and yoke. This method results in low magnetic field efficiency and high temperature rise. To reduce the temperature rise, one could increase the amount of wire used, but this would increase production costs; alternatively, adding a stationary iron core inside the cylindrical tube could improve electromagnetic attraction and efficiency, but this would also increase production costs. During operation, the stationary and moving iron cores would attract and collide, easily damaging their protective layers, leading to rust and contamination of the medium. The induction coil structure effectively solves this problem by reducing the number of insulated wires in the middle and concentrating them at both ends. This maintains the number of insulated wires at the two poles with the stronger magnetic field while reducing the number of insulated wires at the weaker poles, thus reducing costs. Additionally, reducing the number of insulated wires also lowers the temperature rise.

[0035] The solenoid valve is described as having an internal induction coil structure that drives the movement of the iron core inside the pipe, allowing the opening and closing of the solenoid valve to be controlled by the induction coil structure, thus better adjusting the opening and closing status of the solenoid valve.

[0036] The electromagnetic fluid pump includes an induction coil structure and a pipeline. A conductive fluid flows through the pipeline, and the induction coil structure provides electromagnetic force, driving the fluid to flow in the direction of the electromagnetic force. The pump eliminates the need for valve cores and other pump components inside the pipeline, resulting in a lightweight pump body and reduced overall cost. Furthermore, the pump body prevents corrosion of pump components caused by conductive fluids, extending the service life of the electromagnetic fluid pump. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] Firstly, see Figure 1-16 This invention provides an induction coil structure 1, including at least one wound coil 11, at least one magnetic yoke 14, and a frame 12. The frame 12 includes a skeleton 123 and a retainer 122, which are connected. The wound coil 11 is disposed on the outer wall of the skeleton 123. At least one mounting position 125 is provided inside the skeleton 123, and the magnetic yoke 14 is disposed on the mounting position 125. The number of mounting positions 125 matches the number of magnetic yokes 14, with one magnetic yoke 14 disposed on each mounting position 125. The retainer 122 is disposed on the outer periphery of the wound coil 11. The wound coil 11, the magnetic yoke 14, and the retainer 122 form a closed-loop magnetic field. The wound coil 11 is formed by winding an insulated wire. The winding density of the wound coil 11 at both ends of the skeleton 123 is greater than that of the wound coil 11 in the middle of the skeleton 123.

[0043] Specifically, the winding coil 11 and the magnetic yoke 14 are respectively disposed on the frame 123, the cage 122 is disposed on the outside of the frame 123, the winding coil 11 is installed on the outside of the frame 123, the cage 122, the magnetic yoke 14 and the magnetizing element 13 serve as magnetic conductors, the magnetic yoke 14 is installed on the mounting position 125 inside the frame 123, the winding coil 11 generates a magnetic field after being energized, the external magnetic field is guided by the cage 122, the magnetic yoke 14 guides the internal magnetic field, and together with the cage 122, the magnetic field forms a closed loop. In this embodiment, two magnetic yoke rings 14 are provided, including an upper magnetic yoke ring 141 and a lower magnetic yoke ring 142. Two mounting positions 125 are provided, including a first mounting position 125a and a second mounting position 125b. The upper magnetic yoke ring 141 is disposed on the first mounting position 125a, and the lower magnetic yoke ring 142 is disposed on the second mounting position 125b. The specific number of magnetic yoke rings 14 and mounting positions 125 provided is not limited to the two provided in this embodiment, and can be set according to the specific actual situation.

[0044] Among them, the winding coil 11 is a solenoid coil. The insulated wires that make up the winding coil 11 can be any type of wire with an insulating protective layer, such as enameled wire or electrical wire, which can ensure that the wires are kept insulated from each other during winding. When current is applied to the winding coil, the generated electromagnetic force is along the axial direction of the winding coil.

[0045] In one embodiment, the induction coil structure 1 may not have a frame 123. In the winding coil structure 1, the insulated wire is wound into a winding coil 11 by winding it in a mold, and then the mold is removed from the winding coil 11 to complete the production of the winding coil 11. Alternatively, it can be directly wound into a coil. That is, the winding coil 11 itself is strong enough that the frame 123 does not need to be set inside, thereby achieving sufficient support and forming a spiral coil.

[0046] The retainer 122 is sleeved on the outside of the frame 123. The retainer 122 and the frame 123 are respectively provided with through holes. The through holes can be used to install pipes and other mechanisms for fluid transmission. Magnetic components, such as iron cores, are installed inside the pipes. The magnetic field applied by the winding coil 11 drives the magnetic components to move inside the pipes.

[0047] It is understood that the outer wall of the skeleton 123 is wound with a wire with an insulating layer, the coil 11 is wound around it, the magnetic yoke 14 is set inside, and the cage 122 is set outside the skeleton 123. The magnetic yoke 14, the coil 11, and the cage 122 form a closed magnetic field. The magnetic yoke 14 and the cage 122 are set on the induction coil structure 1, which can conduct magnetism from the inside and outside of the skeleton 123 respectively. This allows the direction of the magnetic field generated by the energized coil 11 to be along the magnetic yoke 14 and the cage 122, which can increase the magnetic field strength of the magnetic field generated by the coil 11. It can guide and concentrate the magnetic field lines. The magnetic field generated by the magnetic yoke 14 and the cage 122 is superimposed with the magnetic field of the coil 11 itself, which significantly enhances the overall magnetic field strength. The addition of the magnetic yoke 14 and the cage 122 can enhance the magnetic field. The coil 11 can generate a stronger electromagnetic force or induced electromotive force under the same current, reducing energy loss.

[0048] Furthermore, the wound coil 11 is mounted on the frame 123. When the wound coil 11 is energized, it can generate a magnetic field. The wound coil 11 is formed by winding with insulated wires. The number of insulated wires at both ends of the frame 123 is greater than the number of insulated wires in the middle. This allows the induction coil structure 1 to retain the insulated wires at both ends with higher magnetic field strength, while reducing the number of insulated wires in the middle of the frame 123. This allows for a higher magnetic field strength at both ends of the magnetic poles, thereby reducing the amount of insulated wires used in the middle of the wound coil 11, reducing the overall cost and power consumption of the induction coil structure 1.

[0049] In addition, when the induction coil structure 1 is set with segmented winding coils 11, the winding density of the winding coil 11 set in the middle of the frame 123 is generally less than that of the winding coils set at both ends of the frame 123. This can reduce the number of wires with insulation layer on the winding coil 11 in the middle, reduce the amount of wires with insulation layer used in the middle of the winding coil 11, and reduce the overall cost and power of the induction coil structure 1.

[0050] Optionally, the skeleton 123 is made of any insulating material such as plastic, rubber, or ceramic. That is, the skeleton 123 is not magnetic and does not affect the magnetic field generated by the magnetic yoke 14, the cage 122, or the winding coil 11.

[0051] The induction coil structure 1 includes at least one magnetizing element 13, which is disposed in the middle of the wound coil 11 or between two adjacent wound coils 11. Specifically, the magnetizing element 13 is used to enhance the magnetic force. Because existing coils generate a large instantaneous current when energized, resulting in poor magnetic focusing ability, adding a magnetizing element 13 between the wound coils 11 or between adjacent wound coils 11 can reduce the instantaneous current, increase heat dissipation, and enhance the magnetic field. Specifically, when the wound coil 11 is energized, the magnetizing element 13 impedes the instantaneous current in multiple parts, and the induced current conducted to the magnetizing element 13 is correspondingly canceled, thus reducing the instantaneous current. Since the magnetizing element 13 is magnetic, the magnetic field around it is enhanced, thereby increasing the electromagnetic force on the magnetic components installed around the induction coil structure 1.

[0052] Specifically, the magnetizing element 13 is disposed on the frame 123. The position of the magnetizing element 13 can be adjusted according to the requirements. The magnetizing element 13 can be close to the corresponding magnetic yoke ring 14, thereby enhancing the magnetic field generated by the corresponding magnetic yoke ring 14 and generating a stronger electromagnetic force. Placing the magnetizing element 13 between two adjacent magnetic yoke rings 14 can make the magnetic field strength generated by the two magnetic yoke rings 14 equal.

[0053] The magnetizing component 13 is arranged in a ring (e.g., Figure 9-11As shown, the magnetizing component 13 is sleeved on the frame 123 and surrounds the outer wall of the frame 123. The frame 123 has at least one placement block 121, which is sleeved on the outside of the frame 123 and detachably connected to the frame 123. The magnetizing component 13 has a locking position 131 and an arc-shaped groove 1211 in which the magnetizing component 13 is installed. In addition, the placement block 121 has a limiting member 1212 on the arc-shaped groove 121, which matches the locking position 131. It can be understood that the magnetizing component 13 can be directly wrapped around the frame 123, or the placement block 121 can be provided on the frame 123 for installing the magnetizing component 13. The placement block 121 can prevent the magnetizing component 13 from moving on the frame 123 and facilitates installation.

[0054] Specifically, the magnetizing element 13 surrounds the placement block 121 on the frame 123, and the placement block 121 is provided with an arc-shaped groove 1211 that matches the shape of the magnetizing element 13 (e.g., Figure 12-13 As shown in the diagram, during installation, the magnetizing component 13 is installed according to the outer shape of the arc-shaped groove 1211. During installation, a locking position 131 is provided on the magnetizing component 13. The magnetizing component 131 is installed according to the position of the limiting member 1212 on the frame 123, making installation more convenient. Furthermore, the locking position 131 can fix the magnetizing component 13 to the limiting member 1212 on the frame 123, preventing it from falling off. When the winding coil 11 is energized, the magnetizing component 13 will impede the instantaneous current in both parts, and the induced current conducted to the magnetizing component 13 will be correspondingly canceled out, thus reducing the instantaneous current.

[0055] In one embodiment, the magnetizing component 13 is configured as a separate unit, consisting of multiple components arranged in a ring around the outer side of the frame 12. Each magnetizing component 13 includes at least two magnetic elements, and all the magnetic elements can form a ring. In this embodiment, as shown... Figure 12-15As shown, the magnetizing component 13 is a split structure, comprising a first magnetic sheet 132 and a second magnetic sheet 133, which form a ring. The magnetizing component 13 is an arc-shaped sheet, mounted on the frame 123 in a ring shape, and the first and second magnetic components are fastened together on the frame 123. Furthermore, grooves 263 are provided on both the first and second magnetic components, forming a locking position 131 that engages with the limiting member 1212 on the corresponding placement block 121. It can be understood that by installing the magnetizing component 13 as a separate first and second magnetic component, it can be installed onto the frame 123 after the frame 123 is manufactured, making installation more convenient.

[0056] In one embodiment, the magnetizing component 13 is cylindrical and disposed on the frame 123. The retainer 122 is disposed on the outside of the frame 123. When the wound coil 11 is energized, it generates a magnetic field. The external magnetic field is guided by the retainer 122, and the magnetic yoke 14 guides the internal magnetic field. Together with the retainer 122, they form a closed loop of magnetic field. During this process, the magnetizing component 13 can enhance the magnetic force. Correspondingly, the placement block 121121 is cylindrical and disposed on the outside of the frame 123, and is integrally formed with the frame 123. The locking position 131 is set corresponding to the limiting component 1212, and the magnetizing component 13 is fixed on the frame 123.

[0057] As one embodiment, the magnetizing element 13 is made of a magnetically conductive material or a non-magnetically conductive material. Specifically, the magnetizing element 13 is made of a magnetically conductive material, which can be any of a ferromagnetic material or a ferrimagnetic material. In this embodiment, the magnetizing element 13 is made of a ferromagnetic material and is made into a sheet shape. Alternatively, the magnetizing element 13 can be made of a non-magnetically conductive material, such as plastic, to avoid the generation of eddy currents on the magnetizing element 13, thereby reducing the temperature rise effect.

[0058] As one embodiment, an air gap is provided between the magnetizing component 13 and the retainer 122, and there is a certain distance between the magnetizing component 13 and the retainer 122. The larger the air gap, the stronger the magnetic field. In addition, in order to increase the magnetic shielding effect and suppress eddy currents, the size of the air gap can be reduced. In fact, no air gap is provided between the magnetizing component 13 and the retainer 122, that is, the edge of the magnetizing component 13 contacts the inner wall of the retainer 122, thereby maximizing the magnetic shielding and eddy current suppression effects.

[0059] The induction coil structure 1 includes a first contact piece 16 and a second contact piece 17, which are mounted on the retainer 122. The wound coil 11 includes two terminals, and the first contact piece 16 and the second contact piece 17 are each connected to one terminal. Specifically, the first contact piece 16 and the second contact piece 17 are connected to a power source, and they are simultaneously connected to all the wound coils 11 to supply power to them.

[0060] Optionally, the induction coil structure 1 includes a diode, one end of which is connected to any one of the winding coils 11, and the other end of which is connected to either the first contact 16 or the second contact 17. The diodes connected to the winding coils 11 at both ends of the frame 123 have different directions, so that when AC power is applied, the current directions at both ends are different, resulting in different applied electromagnetic forces. This allows the magnetic actuator inside the pipe mounted on the induction coil structure 1 to reciprocate. It can be understood that the diode is used to fix the current direction, or to fix the current direction according to human needs. When DC power is applied to the winding coils 11 in the induction coil structure 1, since the linear input direction is fixed, the terminals of the winding coils 11 do not need to be connected to diodes. When AC power is applied to the winding coils 11, the direction changes rapidly or the input direction is variable, causing the magnetic actuator to remain in its original position or vibrate in its original position inside the pipe. To allow the magnetic actuator to move, a diode is needed to cut off the AC power, fixing the direction of the AC input current, thereby fixing the direction of the magnetic field and electromagnetic force generated by the winding coils 11.

[0061] A winding coil 11 is provided on the frame 123. The number of winding coils at both ends of the winding coil 11 is greater than the number of winding coils in the middle. On a winding coil 11, the density of the insulated wires is high at both ends and low in the middle. Since the magnetic field strength is the greatest at both ends of the winding coil 11 and the weakest in the middle, the amount of insulated wires used in the middle is greatly reduced, which can greatly reduce the amount of insulated wires used and reduce costs.

[0062] Specifically, the middle part of the wound coil 11 may only have a single insulated wire (e.g., Figure 4-7 (As shown). It can be understood that the number of insulated wires in the middle of the winding coil 11 can be reduced. In order to greatly reduce the number of insulated wires used, the number of insulated wires in the middle can be reduced to one. While ensuring that the winding coil 11 can be electrically connected normally, the number of insulated wires in the middle is reduced, and the amount of copper used in the winding coil 11 is reduced.

[0063] In one embodiment, a magnetizing element 13 is provided in the middle of a wound coil 11. The magnetizing element 13 can divide the wound coil 11 into two parts by the insulated wire. When the insulated wire is energized, the magnetizing element 13 will simultaneously impede the instantaneous current in both parts, and the induced current conducted to the magnetizing element 13 will cancel each other out. The magnetic field around the magnetizing element 13 will be enhanced, and the magnetic force on the iron core 221 will be enhanced when energized. The magnetizing element 13 has strong thermal conductivity, which can quickly conduct the heat inside the coil to the outside. The magnetizing element 13 divides the wound coil 11 into two sections and is located in the middle of the wound coil 11. Therefore, the location of the magnetizing element 13 does not require the winding coil 11 to be set, and it can provide a large magnetic force. Together with the magnetic yoke 14, it can magnetically attract the magnetic components in the pipe, so that the magnetic components can move horizontally in the pipe. In addition, the magnetizing element 13 can be moved closer to any segment of the frame 123 to enhance the magnetic field strength at any end, thereby making the electromagnetic force generated at the corresponding end stronger, so as to meet the different electromagnetic force requirements at different ends.

[0064] Induction coil structure 1 is provided with at least two wound coils 11 (e.g. Figure 8 As shown, the wound coils 11 are connected in parallel, and the wound coils 11 are segmented and arranged on the outer wall of the frame 123. The winding density of the wound coils 11 at both ends of the frame 123 is a first density, and the winding density of the wound coils 11 in the middle of the frame 123 is a second density. The first density is greater than the second density. The wound coils 11 are arranged equidistantly or unequally on the frame 123, and the current flowing between any two wound coils 11 is in the same or opposite direction.

[0065] It is understood that the induction coil structure 1 is provided with at least two wound coils 11, that is, it adopts a segmented winding coil 11 configuration. The winding density of the winding coil 11 located in the middle of the frame 123 is generally less than that of the winding coils 11 located at both ends of the frame 123. This reduces the number of insulated wires on the winding coil 11 in the middle, thereby reducing the overall cost and power consumption of the induction coil structure 1. Furthermore, different current values ​​can be input to each winding coil 11, allowing the induction coil structure 1 to apply different electromagnetic forces on the corresponding segments. This allows for better application of electromagnetic forces to handle varying magnitudes, enabling precise drive control.

[0066] When the winding coil 11 is set up with segmented coils, the winding coil 11 is set on the frame 123 at equal or unequal intervals. The distance between the winding coils 11 can be set according to the electromagnetic force required at the actual corresponding position to adapt to the actual needs at the current position.

[0067] according to Figure 16 As can be seen, the large-diameter curve and the small-diameter curve of the segmented coil in the figure are the electromagnetic force simulation curves generated by the segmented coil of the current application, while the large-diameter curve and the small-diameter curve of the traditional coil are the electromagnetic force simulation curves generated by the traditional coil. The above curves are obtained under the condition that the stroke balance point is the same.

[0068] Specifically, the current application pertains to a segmented coil. Traditional coils, whether large or small diameter, are entirely wound around a frame. Compared to traditional coils, segmented coils provide a greater initial acceleration to the magnetic components within the pipe, generating a larger and faster electromagnetic force. Furthermore, segmented coils more effectively provide a greater electromagnetic force at the initial position, better reducing the risk of jamming of magnetic components within the pipe. Further, such as... Figure 16 As shown in the two conventional coil curves, the electromagnetic force of a conventional coil gradually decreases after reaching its maximum value, resulting in a peak value. However, as shown in the two segmented coil curves, the induction coil structure 1 of this application can achieve a first peak value in electromagnetic force, followed by a second peak value over a subsequent period. That is, two peak values ​​will appear, with the first peak value representing the maximum electromagnetic force. In the electromagnetic force simulation curve of the segmented coil, compared to the electromagnetic force simulation curve of the conventional coil, the segmented coil can provide a larger electromagnetic force. At the same time, the electromagnetic force reaches the first peak value faster, and the segmented coil responds more quickly. Due to the two peak values, the high electromagnetic force can be sustained for a longer period, resulting in a longer stroke.

[0069] In this embodiment, the position detection of the magnetic actuator is achieved by the movement of the piston. The piston moves synchronously with the magnetic actuator, and the piston provides driving force to the magnetic actuator. The segmented coil is set with two wound coils. When the segmented coil uses more than two wound coils, the electromagnetic force simulation curve of the segmented coil winding can show more than two peaks. Correspondingly, the electromagnetic force with higher values ​​lasts for a longer time and maintains a longer stroke.

[0070] In one embodiment, two winding coils 11 are provided on the frame 123 (e.g., Figure 8-9As shown, the device includes a first wound coil 11a and a second wound coil 11b, which are sequentially arranged on the outer surface of the frame 123. The first wound coil 11a and the second wound coil 11b are respectively positioned close to both ends of the frame 123. When energized, alternating current can be input. This alternating current can change the direction of the current input to the first wound coil 11a and the second wound coil 11b within a certain time. By changing the direction of the current in the first wound coil 11a and the second wound coil 11b, the direction of movement of the magnetic component inside the pipe can be altered. The first wound coil 11a and the second wound coil 11b are connected in parallel. The first wound coil 11a includes a first terminal 111 and a second terminal 112, and the second wound coil 11b includes a third terminal 113 and a fourth terminal 114. The first terminal 111 and the third terminal 113 are connected to a first contact piece 16, and the second terminal 112 and the fourth terminal 114 are connected to a second contact piece 17.

[0071] In order to increase the magnetic field strength generated by the two wound coils 11, a magnetizing element 13 can be provided in the space between the first wound coil 11a and the second wound coil 11b. The magnetizing element 13 can increase the magnetic field strength generated between the first wound coil 11a and the second wound coil 11b.

[0072] When either the first winding coil 11a or the second winding coil 11b requires a greater electromagnetic force, the magnetizing element 13 can be placed closer to the corresponding winding coil 11 to increase the magnetic field strength of that winding coil 11, thereby enhancing the electromagnetic force generated by the winding coil 11. For example, if the electromagnetic force generated at the location of the first winding coil 11a needs to be adjusted and increased, the magnetizing element 13 can be placed closer to the first winding coil 11a to improve the electromagnetic force generated by the first winding coil 11a, thus providing a greater driving force.

[0073] The direction of the current input to the first winding coil 11a is opposite to the direction of the current input to the second winding coil 11b. Specifically, the first winding coil 11a and the second winding coil 11b are disposed at both ends of the frame 123. Because the directions of the current input to the first winding coil 11a and the second winding coil 11b are different, the direction of the electromagnetic force generated by the first winding coil 11a is opposite to the direction of the electromagnetic force generated by the second winding coil 11b. Under the action of the electromagnetic force generated by the first winding coil 11a or the electromagnetic force generated by the second winding coil 11b, the magnetic actuator inside the pipe moves in different directions, and the magnetic actuator can reciprocate in the pipe.

[0074] Optionally, direct current (DC) or alternating current (AC) can be input to the first winding coil 11a and the second winding coil 11b. When DC is input, the winding directions of the first winding coil 11a and the second winding coil 11b are different, and the terminals of the winding coils 11 are connected in parallel, so that the direction of the electromagnetic force generated by the first winding coil 11a is opposite to the direction of the electromagnetic force generated by the second winding coil 11b after the power is input. When AC is input, the current input coil can be controlled by diodes disposed on the first contact piece 16 and the second contact piece 17. The diodes are disposed in opposite directions, so that the power is selectively input to either the first winding coil 11a or the second winding coil 11b, thereby applying electromagnetic forces in different directions at both ends of the frame 123.

[0075] Optionally, in order to make the input current of the first winding coil 11a or the second winding coil 11b controllable, an adjustable load can be set on the first contact piece 16 and the second contact piece 17, and the input current can be changed by changing the size of the load.

[0076] In one embodiment, the frame 123 is provided with more than two wound coils 11. The wound coils 11 are arranged in segments and can be installed on the frame 123 at equal or unequal intervals to provide electromagnetic force at corresponding positions. Optionally, the wound coils 11 can be evenly arranged at both ends of the frame 123, or arranged at equal intervals along the frame 123.

[0077] Specifically, a magnetizing element 13 is provided between adjacent wound coils 11. It can be understood that there are multiple wound coils 1111, and the number of magnetizing elements 13 corresponds to one less wound coil 11. The wound coils 11 and the magnetizing elements 13 are together on the frame 123, and the wound coils 1111 are electrically connected. The wound coils 11 on the frame 123 are segmented. Compared to setting a single coil segment on the frame 123, segmenting them saves costs and reduces the amount of insulated wire used. Furthermore, segmenting the wound coils 11 allows for individual electrical control of each wound coil 11, thereby making the direction and magnitude of the electromagnetic force generated by each wound coil 11 controllable.

[0078] The number of magnetic yokes 14 can be increased to correspond to multiple wound coils 11. It is not limited to using two magnetic yokes 14; multiple magnetic yokes 14 can be used. This allows the corresponding wound coils 11 to better conduct magnetism within the frame 123 through the magnetic yokes 14, ensuring magnetic field strength. The number of magnetic yokes 14 is set according to the actual situation. As one embodiment, the winding density of the insulated wire and the length of the wound coil 11 are adjusted according to the actual magnitude of the applied electromagnetic force. It can be understood that when a larger electromagnetic force needs to be applied, the winding density of the insulated wire or the length of the wound coil 11 can be increased, thereby generating a larger electromagnetic force under the same current value. Conversely, when a smaller electromagnetic force needs to be applied, the density of the insulated wire or the length of the wound coil 11 can be reduced accordingly.

[0079] As one embodiment, the induction coil structure 1 is initially powered by an input power source. A preset first current value is applied to the winding coil 11 in the middle of the frame 123. After a preset third time period of applying the first current value, a preset second current value is applied to the winding coil 11 in the middle of the frame 123. The first current value is greater than the second current value.

[0080] Specifically, during startup, a large current value is applied to the winding coil 11, which generates an electromagnetic force that produces a magnetic force on the magnetic actuator installed inside the induction coil structure 1. After startup, the applied current value drops to a second current value, which can meet the needs of providing a large driving force in the initial state at certain specific locations. For example, when the magnetic actuator is started, the inside of the pipe cavity 200 where it is located is in a dry state. The magnetic actuator needs to overcome a large resistance inside the pipe cavity 200, resulting in a larger driving force required than under normal conditions. Therefore, during startup, a larger current needs to be provided to the winding coil 11 in the middle to provide a larger driving force to the iron core 221, thereby starting the iron core 221.

[0081] As one embodiment, the current value of the winding coil 11 located near both ends of the frame 123 is less than the current value of the winding coil 11 located in the middle of the frame 123. Specifically, the current value input at both ends is less than the current value in the middle, which reduces the electromagnetic force of the magnetic actuator near the ends of the pipe, slows down its movement to the ends, and prevents it from rapidly approaching the two ends of the pipe, thus preventing water hammer effect when the pipe is transporting liquid and avoiding damage to the inner wall of the pipe; at the same time, the larger current value in the middle allows the magnetic actuator to overcome the force generated by the springs at both ends, enabling the valve core 25 and other mechanisms to move normally.

[0082] When the winding coil is connected to AC power, each winding coil can be connected to a diode or not. For example, if the winding coil at the port is not connected to a diode, the magnetic component will remain stationary or slow down its movement by connecting AC power. If a diode is connected, the movement speed of the magnetic component can be gradually accelerated. The setting of using or not using a diode depends on specific needs.

[0083] As one embodiment, the power supply connected to the wound coil 11 controls the current switching cycle through a timer or PWM signal to control the output flow and pressure stability of the pump.

[0084] In one specific embodiment, the induction coil structure 1 is externally connected to a current regulation module to adjust the current of the coil and reduce energy waste.

[0085] In another specific implementation, the induction coil structure 1 is externally connected to a control module and a display screen, which are used by the operator to control and monitor the working status of the induction coil structure 1, improve work efficiency, and reduce damage to the electromagnetic pump caused by operational errors.

[0086] As one embodiment, the induction coil structure 1 includes an adhesive layer 15, which covers the outer surface of the wound coil 11. The adhesive layer 15 serves to protect the insulated wires of the wound coil 11 and also serves to provide insulation when high voltage is applied.

[0087] Secondly, see Figure 17-25This invention discloses an electromagnetic pump, comprising an induction coil structure 1 and a pump assembly 2. The pump assembly 2 is housed within a frame 123 and surrounded by a magnetic yoke 14. The magnetic induction coil structure 1 provides driving force to the pump assembly 2. The pump assembly 2 contains a cavity 200 with a self-priming and pressurizing function. By applying pressure to the fluid within the cavity 200, the output fluid can generate high pressure, thereby meeting the demand for high-pressure output fluid. However, existing electromagnetic pumps use pure solenoid coils with a large amount of insulated wire. During operation, the magnetic field generated by the coil forms a magnetic circuit with the external cage 122 and the magnetic yoke 14. This method results in low magnetic field efficiency and high temperature rise. To reduce temperature rise, one could increase the amount of wire used, but this would increase production costs. Alternatively, adding a stationary iron core 221 inside the cylindrical tube could improve electromagnetic attraction and efficiency, but this would also increase production costs. Furthermore, during operation, the stationary and moving iron cores 221 would attract and collide, potentially damaging their protective layers, leading to rust and contamination of the medium. The induction coil structure 1 effectively solves this problem by reducing the number of insulated wires in the middle and concentrating them at both ends. This maintains the number of insulated wires at the two poles with the stronger magnetic field while reducing the number of insulated wires at the weaker magnetic field, thus lowering costs. Additionally, reducing the number of insulated wires also reduces temperature rise.

[0088] Pump assembly 2 includes a pipe body 21, a moving assembly 22, a resetting assembly 23, a sealing assembly 24, a valve core 25, and an outlet pipe 26; the pipe body 21 is mounted on the frame 12; the moving assembly 22, the resetting assembly 23, and the valve core 25 are movably disposed within the pipe body 21; the resetting assembly 23 contacts the moving assembly 22; the moving assembly 22 is detachably connected to the valve core 25; the outlet pipe 26 is located on one side of the pipe body 21; the sealing assembly 24 is located between the pipe body 21 and the outlet pipe 26; the sealing assembly 24 includes a sealing head 241, which is located at the end of the valve core 25; the moving assembly 22, the sealing assembly 24, the valve core 25, and the outlet pipe 26 form a sealed cavity 200 within the pipe body 21. When the induction coil structure is energized, the moving component is driven by the magnetic force of the induction coil structure and squeezes the reset component inside the tube, reducing the pressure in the cavity and opening the valve core. When the induction coil structure is de-energized, the reset component resets, increasing the pressure in the cavity and opening the sealing head, reciprocating to pump water. When the wound coil 11 is energized, the moving component 22 is subjected to the magnetic force of the yoke 14 and the magnetizing element 13, squeezing the reset component 23 inside the tube 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 of the cycle, the reset component 23 resets, increasing the pressure in the cavity 200 and opening the sealing head 241, reciprocating to pump water. During this period, the magnetizing element 13 enhances the magnetic force of the yoke 14.

[0089] It is understandable that during operation, when the wound coil 11 is energized, the magnetic yoke 14 and the magnetizing component 13 together generate a magnetic field, which is conducted to the moving component 22. At this time, the magnetizing component 13 strengthens the magnetic force generated by the magnetic flux inside the wound coil 11. Under the action of the magnetic yoke 14, the moving component 22 moves to the left. Simultaneously, 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 within the pipe body 21 increases, and the pressure increases. As the volume of the cavity decreases, the valve core 25 is passively opened to balance the pressure inside the cavity 200. Since the current used is alternating current, after passing through the diode, the current will be reduced to half a cycle. Therefore, during the process of the electromagnetic pump going from being energized to de-energized, the reset component 23 resets after being compressed and deformed, 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 head 241 to open to balance the pressure. The pumping process repeats.

[0090] The induction coil structure 1 and the pump assembly 2 are detachably or fixedly connected. A retainer 122 is sleeved on the outside of the frame 123, and the wound coil 11 is sleeved on the frame 123. The retainer 122 and the frame 123 are each provided with through holes. The tube 21 in the pump assembly 2 passes through the through holes of the retainer 122 and the frame 123. When a part needs to be replaced, the pump assembly 2 is pulled out and replaced. In one specific embodiment, a connector 124 is provided on one side of the frame 12. The connector 124 and the retainer... 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 specific embodiment, the connector 124 and the retainer 122 each have two threaded holes, arranged diagonally, so only two screws are needed to assemble and fix the pump assembly 2 and the induction coil structure 1. In another specific embodiment, the induction coil structure 1 and the pump assembly 2 are detachably connected, that is, the pump assembly 2 is inserted into the through holes of the retainer 122 and the frame 123. When it is necessary to replace the parts, the pump assembly 2 is pulled out and replaced.

[0091] When the induction coil structure 1 is energized, the magnetic force on the moving component 22 is enhanced, and it reciprocates within the tube 21, thus acting as a pump. The magnetizing component 13 not only increases the electromagnetic attraction but also greatly reduces the amount of wires with insulation layers used, thereby reducing costs, lowering power consumption, and increasing efficiency.

[0092] Specifically, the position of the magnetizing element 13 can be set according to the usage requirements of the electromagnetic pump. When a higher pressure and flow rate are required, the magnetizing element 14 can be placed close to the magnetic yoke 14 located at the corresponding position to enhance the magnetic field strength around the magnetic yoke 14, thereby generating a stronger electromagnetic force and obtaining greater pressure and flow. After the electromagnetic pump 1 runs dry, the moving component 22 will encounter greater resistance and stop moving. In addition, placing the magnetizing element 13 in the middle position between two adjacent magnetic yokes 14 can make the electromagnetic force generated by the adjacent magnetic yokes 14 more even.

[0093] In one embodiment, a connector 124 is provided on one side of the frame 12. The connector 124 can be connected to and fixed to the fluid-carrying pipe 21. Both the connector 124 and the retainer 122 have threaded holes. After aligning the through hole of the retainer 122 with the through hole of the frame 123, the pipe 21 is inserted, and then the connector 124 is inserted into the pipe 21. Screws are then screwed sequentially into the threaded holes of the connector 124 and the retainer 122. The connector 124 and the retainer 122 restrict the pipe 21, allowing fluid to enter the pipe 21 from the connector 124. Furthermore, both the connector 124 and the retainer 122 have two threaded holes arranged diagonally, so only two screws are needed to assemble and fix the pipe 21 and the retainer 122.

[0094] The reset assembly 23 includes a first elastic element 231, a second elastic element 232, and a third elastic element 233; the moving assembly 22 includes an iron core 221; the first elastic element 231, the second elastic element 232, and the iron core 221 are respectively movably disposed within the tube body 21; and the iron core 221 is disposed between the first elastic element 231 and the second elastic element 232; the third elastic element 233 is movably disposed within the iron core 221 and is detachably connected to the valve core 25.

[0095] In specific implementation: the first elastic element 231 and the second elastic element 232 are springs, and the third elastic element 233 is a tension spring; the moving component 22 includes an iron core 221, which is made of iron and can move inside the tube 21 after being magnetically attracted. Specifically, after the winding coil 11 is energized, the iron core 221 moves to the left under the magnetic force of the magnetic yoke 14 and the magnetizing element 13. 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 water outlet pipe 26 in the tube 21 increases and the pressure decreases. At this time, the valve core 25 is passively opened to balance the pressure inside the cavity 200. In the next cycle of the current, the first elastic element 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 head 241 to open and pump out the liquid. The first elastic element 231 and the second elastic element 232 are disposed inside the tube body 21 and on both sides of the iron core 221. The second elastic element 232 can buffer the iron core 221. After the winding coil 11 is energized, the magnetic yoke 14 generates magnetic force and moves inside the tube body 21 under the action of magnetic force. When the iron core 221 moves to the left, it will apply pressure to the first elastic element 231. The first elastic element 231 is compressed and deformed after being subjected to force. Then the first elastic element 231 returns to its original position, and the iron core 221 moves to the right, squeezing the second elastic element 232. At this time, the second elastic element 232 buffers the iron core 221 and avoids large wear on the tube body 21.

[0096] In addition, since there is no fluid inside the electromagnetic pump, the iron core may become too dry and unable to move due to the high resistance. By setting up a magnetizing component inside the induction coil structure, the magnetic field strength can be increased, thereby making the electromagnetic force stronger and enhancing the initial electromagnetic force, making it easier for the iron core to overcome the resistance.

[0097] The iron core 221 has a tapered hole 2211 on one side, and the valve core 25 has a limiting block 251 corresponding to the tapered hole 2211. The limiting block 251 is located inside the tapered hole 2211 and is in contact with or away from the tapered hole 2211.

[0098] In specific implementation: the iron core 221 is provided with a conical hole 2211, and the valve core 25 is provided with a limiting block 251 corresponding to the conical hole 2211, and the limiting block 251 is conical and located inside the conical hole 2211; during operation, the iron core 221 drives the valve core 25 to move, so that the valve core 25 contacts or moves away from the conical hole 2211; the conical shape of the conical hole 2211 and the limiting block 251 can limit the valve core 25; when the iron core 221 drives the third elastic element 233 to move to the left, the limiting block 251 of the valve core 25 contacts the conical hole 2211, at which time the conical hole 2211 and the limiting block 251 fit together to limit the valve core 25; the valve core 25 is confined within the accommodating space between the front end of the iron core 221 and the outlet pipe 26.

[0099] The third elastic element 233 is provided with a hook, and the valve core 25 is provided with a circular hole 252; the hook passes through the circular hole 252 and drives the valve core 25 to move in the water outlet pipe 26.

[0100] In specific implementation: the third elastic element 233 is a tension spring, and the hook provided by the tension spring is installed in conjunction with the circular hole 252 provided by the valve core 25. That is, the hook is passed through the circular hole, so that the valve core 25 can move under the drive of the third elastic element 233 to realize the opening and closing of the valve core 25. The assembly method of the hook and the circular hole 252 makes it easy to disassemble and replace.

The abutment blocks 2622 are arranged crosswise at the center of the seat 262 and are also provided with hollowed-out portions for liquid to flow.

[0105] Specifically, when the sealing head 241 is displaced in the horizontal direction, the fourth elastic element 261 will deform or reset; when the iron core 221 moves to the right, the sealing head 241 is opened, moves to the right and squeezes the fourth elastic element 261, causing the fourth elastic element 261 to be compressed and deformed; then the fourth elastic element 261 resets.

[0106] Please refer to Figures 19-20 The front end of the sealing head 241 is provided with an arc-shaped block 2411, and the water outlet pipe 26 is provided with a groove 263 corresponding to the front end.

[0109] In specific implementations: In one embodiment, the outer side of the iron core 221 is coated with a nano-coating; this prevents rusting and contamination of the medium; reduces wear and tear, and improves service life. In another embodiment, the inner wall of the tube 21 is provided with a buffer layer, either by brushing or by forming a cylinder and directly fitting it inside; this buffers the movement of the iron core 221 within the tube 21.

[0110] Please refer to Figure 24 and Figure 25 , Figure 24 The coil has no magnetizing components, and the coil wire diameter is 0.23mm, with a weight of 150g; Figure 24 It can be seen that the temperature rise of the coil at this time is 141.64547619. Figure 24 The coil is equipped with a magnetizing component, and the coil wire diameter is 0.18mm, with a weight of 80g; Figure 25It can be seen that the temperature rise of the coil at this time is 84.59421488. In summary, after adding the magnetizing element 13 to the wound coil 11, the temperature rise of the wound coil 11 is much smaller than that without the magnetizing element 13, and the flow rate change rate is small, making it more stable. It can be seen that the magnetizing element 13 has strong thermal conductivity, which can conduct the heat inside the wound coil 11 to the outside, reducing the temperature rise. At the same time, the weight of the insulated wire used is small, which can greatly reduce the cost.

[0111] As one embodiment, the control of the electromagnetic pump 100 is specifically operated as follows: The winding coil 11 inside the magnetic induction coil mechanism is energized, and the current value is configured according to the actual electromagnetic force required to be applied to the iron core 221 at the corresponding position of the winding coil 11. After energizing the winding coil 11 in the first current direction for a preset first time period, the current direction is changed, and the winding coil 11 is energized in the second current direction for a preset second time period. The winding coil 11 is alternately energized in the first current direction and the second current direction to control the movement direction of the iron core 221.

[0112] Specifically, after the magnetic coil mechanism is installed on the pump assembly 2, before the electromagnetic pump 100 operates, it is necessary to determine the required electromagnetic force at different positions of the core 221 on the magnetic coil mechanism. Based on parameters such as the electromagnetic force and the number of turns of the winding coil 11, the corresponding input current value of the winding coil 11 is calculated. The electromagnetic force is precisely controlled according to actual needs to adapt to different operating conditions and achieve adjustable pump output flow and pressure. By changing the direction of the current, the polarity of the generated magnetic field is altered, causing the electromagnetic force to change with the current direction. This electromagnetic force drives the core 221 to reciprocate within the tube 21. Driving the core 221 with electromagnetic force improves the response speed and enables high-frequency operation. The winding coil 11 alternately changes the current direction, thereby controlling the movement direction of the core 221, enabling it to reciprocate and pump out high-pressure liquid. This continuous alternation allows for continuous liquid delivery.

[0113] It is understandable that by energizing the induction coil structure 1, an electromagnetic force can be provided to the iron core 221, thereby driving the iron core 221 to move. Since the iron core 221 requires different electromagnetic forces to drive it at different positions in the pipeline, the current applied to the winding coil 11 on the induction coil structure 1 needs to be different and needs to be configured accordingly for different positions in the pipeline. Furthermore, the electromagnetic pump 100 needs to be turned on or off, requiring the iron core 221 to move in two different directions. By changing the direction of the current applied to the induction coil structure 1, the direction of movement of the iron core 221 can be controlled. Pump 100 turns on or off. The electromagnetic pump 100 is improved by magnetizing the coil. The direction of the current is changed alternately, so that the electromagnetic force is continuously changed in alternating directions. The iron core 221 inside the pump assembly 2 continuously reciprocates, realizing the liquid suction and discharge process of the inner cavity 200 of the pump assembly 2. The pump assembly 2 can continuously output fluid and operate efficiently and reliably. The movement of the iron core 221 is controlled by the electromagnetic force generated by the wound coil 11, avoiding direct driving of the iron core 221 and reducing the energy consumption required by the pump assembly 2.

[0114] Furthermore, the different current values ​​input to the winding coil 11 at different positions result in different electromagnetic forces, making it suitable for situations where different electromagnetic forces are required at different locations. This allows for controllable speed and position of the iron core 221. For example, near the water outlet, the speed of the iron core 221 can be gradually reduced to prevent water hammer caused by excessively fast movement.

[0115] As one embodiment, the winding coil 11 is connected to AC or DC power. When connected to AC power, a diode can be connected to control the direction of the current input. When connected to DC power, the DC power can be input according to the winding direction of the winding coil 11, so that the iron core 221 in the pump assembly 2 can achieve reciprocating motion.

[0116] As one embodiment, the current value flowing through the winding coil 11 near both ends of the pipe is less than the current value flowing through the winding coil 11 in the middle of the pipe. Specifically, the current value input at both ends is less than the current value in the middle, which reduces the electromagnetic force on the iron core 221 near the ends of the pipe, slowing down its speed when moving to the ends and preventing it from rapidly approaching the two ends of the pipe, thus preventing water hammer effect; at the same time, the larger current value in the middle allows the iron core 221 to overcome the force generated by the springs at both ends, enabling the iron core 221 and the valve core 25 and other mechanisms to move normally.

[0117] As one embodiment, during startup, a preset first current value is applied to the winding coil 11 in the middle of the pipe; after startup, after a preset third time period, a preset second current value is applied to the winding coil 11 in the middle of the pipe, and the first current value is greater than the second current value.

[0118] Specifically, during startup, a large current value is applied to the iron core 221. After a period of time following startup, the current value of the power supply applied to the iron core 221 drops to a second current value. This can meet the needs of providing a large driving force in the initial state at certain specific locations. For example, when the pump assembly 2 starts, the inside of the cavity 200 is in a dry state, and the iron core 221 needs to overcome a large resistance in the cavity 200, resulting in a greater driving force required than under normal circumstances. Therefore, during startup, a larger current needs to be provided to the winding coil 11 in the middle to provide a greater driving force to the iron core 221, thereby enabling the iron core 221 to start.

[0119] As one embodiment, the power supply connected to the wound coil 11 controls the current switching cycle through a timer or PWM signal to control the output flow and pressure stability of the pump.

[0120] As one embodiment, multiple winding coils 11 are provided and segmented. The winding ratio of the winding coils 11 can be customized so that each segment of the winding generates different electromagnetic forces, thereby achieving diverse motion.

[0121] Thirdly, this invention provides a solenoid valve, including the aforementioned induction coil structure 1 and a pipeline. The solenoid valve is used to control the entry and exit of fluid within the pipeline. Because existing valves open or close too quickly, water hammer can easily occur, damaging the pipeline containing the valve. To address the damage caused by water hammer, existing technologies commonly use proportional valves, PWM regulation, and other methods to regulate the valve. The solenoid valve is equipped with an induction coil structure 1, which is segmented along the pipeline. Each segment of the coil generates a different electromagnetic force, thus adjusting the opening amplitude of the valve core 25. This allows for a gradual change in the opening or closing speed of the solenoid valve; for example, the opening speed gradually increases when opening and gradually decreases when closing. This prevents water hammer from occurring inside the pipeline, protecting the pipeline and equipment connected to the solenoid valve from damage caused by the force of water hammer and extending the service life of the equipment.

[0122] Fourthly, the present invention provides an electromagnetic fluid pump, including the aforementioned induction coil structure 1 and a pipeline. The induction coil structure 1 is disposed outside the pipeline, and generates a magnetic field when energized.

[0123] Specifically, when a conductive fluid flows through a pipe, and the induction coil structure 1 is energized, the fluid generates an electromagnetic force under the influence of a magnetic field. This electromagnetic force provides the driving force for the fluid, causing it to flow along the direction of the electromagnetic force. This design eliminates the need for internal drive components and pump assemblies found in electromagnetic pumps, resulting in a lighter pump structure and reduced overall production costs. Furthermore, the pump body prevents corrosion of the pump assemblies caused by the conductive fluid, extending the pump's service life.

[0124] As one embodiment, the induction coil structure 1 uses multiple coils arranged in segments, which can enhance the magnetization effect. The arrangement of multiple coil segments allows the liquid metal to respond faster, flow faster, and stop faster, so as to meet the requirements of the device for rapid response and ensure the stability of the device.
