[0002] An electromagnetic pump is a pump device that uses an electric current in a magnetic field to achieve the delivery and flow of a liquid.

[0003] An electromagnetic pump generally consists of an electromagnetic coil, a core, a valve and a pump body. When the electromagnetic coil is energized, a magnetic field is generated, causing the core to be subjected to an attractive force or a repulsive force, thereby causing the valve to open or close. At this time, a space with varying volume is formed inside the pump body, and the liquid enters and exits this space through the opening or closing of the valve. When the valve is opened, the liquid is sucked in; when the valve is closed, the liquid is pushed out.

The strength of the electromagnetic coil magnetic field is concentrated at the two poles and is higher than that in the middle of the electromagnetic coil.

[0046] Compared with the prior art, the above technical scheme provided by the application has the following advantages:

[0047] The induction coil structure, the electromagnetic pump, the electromagnetic valve and the electromagnetic fluid pump provided by the application have the following advantages: the two ends of the induction coil structure are reserved with the insulated wires with high magnetic field strength, the insulated wires with the winding coils in the middle part of the framework are reduced, the use amount of the insulated wires with the winding coils in the middle part of the induction coil structure is reduced, the induction coil structure is lightened, and the purpose of low power consumption is achieved.

[0048] In addition, the induction coil structure has at least two winding coils, the winding coils are arranged in sections, the winding density of the winding coils arranged in the middle part of the framework is smaller than the winding density of the winding coils arranged at the two ends of the framework, the number of the insulated wires with the winding coils in the middle part of the winding coils is reduced, the use amount of the insulated wires with the winding coils in the middle part of the induction coil structure is reduced, the induction coil structure is lightened, and smaller power is required under the premise of generating the same electromagnetic force.

[0049] Further, different current values of power can be input to each winding coil, so that the induction coil structure can exert different electromagnetic forces on the corresponding sections, so as to cope with the situation of the size of the corresponding electromagnetic force, and the corresponding electromagnetic force can be better exerted to perform fine driving control.

[0050] Further, the inductive coil structure is provided with a magnetic enhancer. The magnetic enhancer can separate the insulated wire into two parts. When the insulated wire is electrified, the magnetic enhancer can hinder the instantaneous current of the two parts at the same time. The induced current conducted to the magnetic enhancer can be offset. The magnetic field around the magnetic enhancer can be enhanced. The magnetic force of the iron core can be enhanced when electrified. The magnetic enhancer has strong heat conduction, which can quickly conduct the heat inside the coil to the outside.

[0053] Further, the inductive coil structure is provided with a magnetic enhancer. The magnetic enhancer can separate the insulated wire into two parts. When the insulated wire is electrified, the magnetic enhancer can hinder the instantaneous current of the two parts at the same time. The induced current conducted to the magnetic enhancer can be offset. The magnetic field around the magnetic enhancer can be enhanced. The magnetic force of the iron core can be enhanced when electrified. The magnetic enhancer has strong heat conduction, which can quickly conduct the heat inside the coil to the outside.

[0055] In addition, the coil of the existing electromagnetic pump is a pure solenoid coil, and more insulated wires are used. When working, a magnetic field is generated by the coil, and a magnetic circuit is formed by the external retainer and the magnetic yoke. The magnetic field utilization efficiency of this mode is low, and the temperature rise is high. In order to reduce the temperature rise, the use amount of the wire can be increased, but the production cost will be increased. Alternatively, a static iron core is added in the cylindrical pipe to improve the electromagnetic attraction and the use efficiency. However, this mode also increases the production cost, and the static iron core and the moving iron core attract each other during work, which causes impact and easily damages the protective layer of the two, resulting in rust and pollution of the medium. The induction coil structure can well solve this problem. The insulated wire in the middle is reduced, and the insulated wire is concentrated at both ends, so that the insulated wire of the two poles with strong magnetic field is maintained, and the number of insulated wires with weak magnetic field is reduced, so as to reduce the cost. In addition, the number of insulated wires is reduced, and the temperature rise can be reduced.

[0056] The electromagnetic valve is provided with the induction coil structure inside to drive the movement of the iron core in the pipe, so that the opening or closing of the electromagnetic valve is controlled by the induction coil structure, and the opening or closing of the electromagnetic valve is better adjusted.

[0057] The electromagnetic fluid pump comprises the induction coil structure and the pipe. The pipe is filled with a fluid with electrical conductivity. The induction coil structure provides electromagnetic force to drive the fluid in the pipe to flow in the direction of the electromagnetic force. The pump body is lightened, and the overall cost is reduced. In addition, the fluid with electrical conductivity can corrode the pump components, and the pump body can avoid the corrosion of the fluid to the pump components, thereby prolonging the service life of the electromagnetic fluid pump.

Best mode for carrying out the invention

[0089] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0090] In a first aspect, referring to FIGS. 1-16, the present application provides an inductor structure 1, comprising at least one winding coil 11, at least one magnetic yoke 14, a frame body 12, the frame body 12 comprising a skeleton 123 and a retaining frame 122, the skeleton 123 and the retaining frame 122 being connected, the winding coil 11 being arranged on the outer wall of the skeleton 123, at least one mounting position 125 being arranged in the skeleton 123, the magnetic yoke 14 being arranged on the mounting position 125, the number of mounting positions 125 being matched with the number of magnetic yokes 14, one magnetic yoke 14 being arranged on one mounting position 125. The retaining frame 122 is arranged on the outer periphery of the winding coil 11, the winding coil 11, the magnetic yoke 14 and the retaining frame 122 form a closed loop magnetic field, the winding coil 11 is wound by a conductor with an insulating layer, and the winding density of the winding coil 11 at both ends of the skeleton 123 is greater than the winding density of the winding coil 11 at the middle of the skeleton 123.

[0091] Specifically, the winding coil 11 and the magnetic yoke 14 are arranged on the skeleton 123 respectively, the retaining frame 122 is arranged outside the skeleton 123, the winding coil 11 is mounted outside the skeleton 123, the retaining frame 122, the magnetic yoke 14 and the magnetic enhancer 13 act as a magnetic conductor, the magnetic yoke 14 is mounted on the mounting position 125 inside the skeleton 123, the winding coil 11 generates a magnetic field after being energized, the external magnetic field is guided by the retaining frame 122, the magnetic yoke 14 guides the internal magnetic field, and the magnetic yoke 14 and the retaining frame 122 jointly act to form a closed loop magnetic field. In this embodiment, the magnetic yoke 14 is provided as two, including an upper magnetic yoke 141 and a lower magnetic yoke 142, the mounting position 125 is provided as two, including a first mounting position 125a and a second mounting position 125b, the upper magnetic yoke 141 is arranged on the first mounting position 125a, and the lower magnetic yoke 142 is arranged on the second mounting position 125b. The number of magnetic yokes 14 and mounting positions 125 is not limited to two in this embodiment, and can be appropriately arranged according to actual conditions.

[0092] The winding coil 11 is a solenoid coil, and the insulated wire used to form the winding coil 11 can be any wire with an insulating layer, such as enameled wire or electric wire, which can ensure that the wires are insulated from each other during winding. When an electric current is applied to the winding coil, an electromagnetic force is generated in the axial direction of the winding coil.

[0093] As an embodiment, the skeleton 123 can not be provided in the induction coil structure 1. In the winding coil structure 1, the insulated wire is wound in a mold to form the winding coil 11, and then the mold is removed from the winding coil 11 to complete the production of the winding coil 11, or the winding coil is directly wound to form the winding coil. That is, the winding coil 11 itself has sufficient strength and can directly not have an internal skeleton 123, thereby achieving sufficient support and forming a spiral coil.

[0094] The retainer 122 is sleeved outside the skeleton 123, and the retainer 122 and the skeleton 123 are respectively provided with through holes for installing pipes or other mechanisms for transmitting fluid. The pipes are provided with magnetic members such as iron cores, which are driven to move in the pipes by the magnetic field generated by the winding coil 11.

[0095] It can be understood that the winding coil 11 formed by winding the insulated wire on the outer wall of the skeleton 123 is provided with a magnetic yoke 14 inside, and the skeleton 123 is provided with a retainer 122 outside. The magnetic yoke 14, the winding coil 11, and the retainer 122 form a closed-loop magnetic field. The magnetic yoke 14 and the retainer 122 provided on the induction coil structure 1 can guide the magnetic field from the inside and outside of the skeleton 123, respectively, so that the direction of the magnetic field generated by the energized winding coil 11 can follow the magnetic yoke 14 and the retainer 122. This can increase the magnetic field strength of the magnetic field generated by the winding coil 11, guide and concentrate the magnetic field lines, and superimpose the magnetic fields generated by the magnetic yoke 14 and the retainer 122 on the magnetic field of the winding coil 11 itself, thereby significantly enhancing the overall magnetic field strength. The addition of the magnetic yoke 14 and the retainer 122 can enhance the magnetic field, and the winding coil 11 can generate a stronger electromagnetic force or induced electromotive force under the same current, thereby reducing energy loss.

[0096] Further, the winding coil 11 is installed on the skeleton 123, and the winding coil 11 can generate a magnetic field when energized. The winding coil 11 is formed by winding the insulated wire, and the number of turns of the insulated wire at both ends of the winding coil 11 is greater than the number of turns of the insulated wire in the middle, so that the induction coil structure 1 retains the insulated wire with a higher magnetic field strength at both ends. Reducing the number of turns of the insulated wire in the middle of the winding coil 11 can reduce the use of the insulated wire in the middle of the winding coil 11, thereby reducing the cost of the overall induction coil structure 1 and reducing the power.

[0097] In addition, when the inductive coil structure 1 is provided with the segmented winding coil 11, the winding density of the winding coil 11 provided in the middle of the framework 123 is smaller than the winding density of the winding coil provided at both ends of the framework 123, which can reduce the number of insulated conductors provided on the winding coil 11 in the middle, reduce the use amount of insulated conductors provided in the middle of the winding coil 11, and reduce the cost and power of the overall inductive coil structure 1.

[0098] Optionally, the framework 123 is made of any insulating material such as plastic, rubber, ceramic, etc., that is, the framework 123 is not magnetically permeable and does not affect the magnetic field generated by the yoke ring 14, the retainer 122, and the winding coil 11.

[0099] The inductive coil structure 1 includes at least one magnetic enhancement member 13 provided in the middle of the winding coil 11 or between two adjacent winding coils 11. Specifically, the magnetic enhancement member 13 is used to increase the magnetic force. Since the existing coil generates a large instantaneous current at the moment of energization, the magnetic aggregation ability is poor. Adding a magnetic enhancement member 13 between the winding coils 11 or between adjacent winding coils 11 can reduce the instantaneous current, increase heat dissipation, and increase the use of the magnetic field. Specifically, when the winding coil 11 is energized, the magnetic enhancement member 13 can hinder the instantaneous current of multiple parts, and the induced current conducted to the magnetic enhancement member 13 can be offset accordingly to reduce the instantaneous current. Since the magnetic enhancement member 13 has magnetism, the magnetic field around the magnetic enhancement member 13 is enhanced, and the electromagnetic force acting on the magnetic member installed around the inductive coil structure 1 is also enhanced.

[0100] Specifically, the magnetic enhancement member 13 is arranged on the framework 123, and the magnetic enhancement member 13 can adjust its own position according to the demand. The magnetic enhancement member 13 can be close to the corresponding yoke ring 14 to enhance the magnetic field generated by the corresponding yoke ring 14 and generate stronger electromagnetic force. Placing the magnetic enhancement member 13 between two adjacent yoke rings 14 can make the magnetic field intensity generated by the two yoke rings 14 flat.

[0101] The magnetic enhancer 13 is arranged in a ring shape (as shown in Figures 9-11), and is sleeved on the framework 123, and surrounds the outer wall of the framework 123. The framework 123 is provided with at least one placement block 121, which is sleeved on the outer side of the framework 123, and is detachably connected with the framework 123. The magnetic enhancer 13 is provided with a clamping position 131, and the placement block 121 is provided with an arc-shaped groove 1211, and the magnetic enhancer 13 is installed in the arc-shaped groove 1211. In addition, the placement block 121 is provided with a limiting piece 1212 on the arc-shaped groove 121, and the limiting piece 1212 is matched with the clamping position 131. It can be understood that the magnetic enhancer 13 can be directly wrapped on the framework 123, or the placement block 121 can be arranged on the framework 123 for installing the magnetic enhancer 13. The placement block 121 can avoid the movement of the magnetic enhancer 13 on the framework 123, and is more convenient to install.

[0102] Specifically, the magnetic enhancer 13 surrounds the placement block 121 on the framework 123, and the arc-shaped groove 1211 matched with the shape of the magnetic enhancer 13 is arranged on the placement block 121 (as shown in Figures 12-13). During installation, the magnetic enhancer 13 is installed according to the shape of the arc-shaped groove 1211. During installation, the clamping position 131 is arranged on the magnetic enhancer 13, and the clamping position 131 is installed according to the position of the limiting piece 1212 on the framework 123. The magnetic enhancer 131 is installed, so that the magnetic enhancer 13 can be installed according to the position of the clamping position 131 on the limiting piece 1212, and the installation is more convenient. In addition, the clamping position 131 can fix the magnetic enhancer 13 on the limiting piece 1212 on the framework 123, to prevent it from falling off. When the wire coil 11 is energized, the magnetic enhancer 13 will hinder the instantaneous current of the two parts, and the induced current conducted to the magnetic enhancer 13 will be correspondingly offset, so as to reduce the instantaneous current.

[0103] As an embodiment, the magnetic enhancer 13 is arranged in a split structure. The magnetic enhancer 13 is split into multiple parts and arranged in a ring shape outside the frame 12. The magnetic enhancer 13 includes at least two magnetic pieces, and all the magnetic pieces can form a ring. In this embodiment, as shown in FIGS. 12-15, the magnetic enhancer 13 is arranged in a split structure. The magnetic enhancer 13 includes a first magnetic piece 132 and a second magnetic piece 133. The first magnetic piece 132 and the second magnetic piece 133 form a ring. The magnetic enhancer 13 is an arc-shaped piece and is installed on the skeleton 123 and arranged in a ring shape. The first magnetic piece and the second magnetic piece are snap-fitted on the skeleton 123. In addition, the first magnetic piece and the second magnetic piece are respectively provided with a groove 263. The groove 263 forms a clamping position 131 and is snap-fitted with the limiting piece 1212 on the placement block 121. It can be understood that the magnetic enhancer 13 is split into the first magnetic piece and the second magnetic piece for installation. The skeleton 123 can be installed on the skeleton 123 after the manufacturing is completed, so that the installation is more convenient.

[0104] As an embodiment, the magnetic enhancer 13 is arranged in a split structure. The magnetic enhancer 13 is split into multiple parts and arranged in a ring shape outside the frame 12. The magnetic enhancer 13 includes at least two magnetic pieces, and all the magnetic pieces can form a ring. In this embodiment, as shown in FIGS. 12-15, the magnetic enhancer 13 is arranged in a split structure. The magnetic enhancer 13 includes a first magnetic piece 132 and a second magnetic piece 133. The first magnetic piece 132 and the second magnetic piece 133 form a ring. The magnetic enhancer 13 is an arc-shaped piece and is installed on the skeleton 123 and arranged in a ring shape. The first magnetic piece and the second magnetic piece are snap-fitted on the skeleton 123. In addition, the first magnetic piece and the second magnetic piece are respectively provided with a groove 263. The groove 263 forms a clamping position 131 and is snap-fitted with the limiting piece 1212 on the placement block 121. It can be understood that the magnetic enhancer 13 is split into the first magnetic piece and the second magnetic piece for installation. The skeleton 123 can be installed on the skeleton 123 after the manufacturing is completed, so that the installation is more convenient.

[0105] As an embodiment, the magnetic enhancer 13 is made of a magnetic material or a non-magnetic material. Specifically, the magnetic enhancer 13 is made of a magnetic material, which can be any one of ferromagnetic material and ferrimagnetic material. In this embodiment, the magnetic enhancer 13 is made of ferromagnetic material and has a sheet shape. In addition, the magnetic enhancer 13 is made of a non-magnetic material, which can be plastic material. The use of the non-magnetic material can avoid the generation of eddy current on the magnetic enhancer 13, thereby reducing the temperature rise effect.

[0106] As an embodiment, an air gap is arranged between the magnetic enhancer 13 and the retaining ring 122. The magnetic enhancer 13 and the retaining ring 122 are spaced apart. The larger the air gap, the higher the magnetic field strength. In addition, in order to achieve the purpose of increasing the magnetic isolation effect and suppressing the eddy current, the size of the air gap can be reduced. Even, the magnetic enhancer 13 and the retaining ring 122 are not arranged with an air gap, that is, the edge of the magnetic enhancer 13 is in contact with the inner wall of the retaining ring 122, so that the magnetic isolation effect and the suppression of the eddy current are maximized.

[0107] The inductive coil structure 1 comprises a first contact sheet 16 and a second contact sheet 17, the first contact sheet 16 and the second contact sheet 17 are installed on the holder 122, the winding coil 11 comprises two wire terminals, and the first contact sheet 16 and the second contact sheet 17 are connected with one wire terminal respectively. Specifically, the first contact sheet 16 and the second contact sheet 17 are connected with a power supply, and the first contact sheet 16 and the second contact sheet 17 are connected with all the winding coils 11 at the same time, so as to supply power for the winding coils 11.

[0108] Optionally, the inductive coil structure 1 comprises a diode, one end of the diode is connected with any winding coil 11, and the other end of the diode is connected with the first contact sheet 16 or the second contact sheet 17. The diodes connected with the winding coils 11 on both ends of the holder 123 are different in direction, so that when alternating current is connected, the current directions of both ends are different, the electromagnetic forces applied are different, and the magnetic action member installed in the pipeline of the inductive coil structure 1 can realize reciprocating motion. It can be understood that the diode is connected in order to fix the current direction or to fix the current direction according to human demand. When the winding coil 11 in the inductive coil structure 1 is connected with direct current, the input direction of the direct current is fixed, and the terminal of the winding coil 11 can not be connected with the diode. When the winding coil 11 is connected with alternating current, the direction changes frequently or the input direction is variable, which will cause the magnetic action member to remain at the original position or vibrate at the original position in the pipeline. In order to move the magnetic action member, the diode needs to be connected to perform chopper processing on the alternating current, so as to fix the input current direction of the alternating current, so that the magnetic field direction generated by the winding coil 11 and the electromagnetic force direction are fixed.

[0109] One winding coil 11 is arranged on the holder 123, the number of turns of the winding coil 11 at both ends is greater than the number of turns of the winding coil 11 at the middle, and the density of the wire with an insulating layer at both ends of one winding coil 11 is high, and the density at the middle is low. Since the magnetic field strength at both ends of the winding coil 11 is the largest, and the magnetic field strength at the middle is the weakest, the amount of the wire with an insulating layer used at the middle is greatly reduced, the use amount of the wire with an insulating layer is greatly reduced, and the cost is reduced.

[0110] In particular, only one wire with an insulating layer can be arranged at the middle of the winding coil 11 (as shown in FIGS. 4-7). It can be understood that the wire with an insulating layer at the middle of the winding coil 11 can be reduced in number. In order to greatly reduce the number of the wire with an insulating layer, the number of the wire with an insulating layer at the middle can be reduced to one. The winding coil 11 can be normally electrically connected, the number of the wire with an insulating layer arranged at the middle is reduced, and the amount of copper used by the winding coil 11 is reduced.

[0111] As an embodiment, the magnetic enhancer 13 is arranged in the middle of the winding coil 11, the magnetic enhancer 13 can separate the insulated conductor wire on the winding coil 11 into two parts, when the insulated conductor wire is electrified, the magnetic enhancer 13 will hinder the instantaneous current of the two parts at the same time, the induced current conducted to the magnetic enhancer 13 will be offset; the magnetic field around the magnetic enhancer 13 will be enhanced, the magnetic force of the core 221 will be enhanced when electrified; the magnetic enhancer 13 has strong heat conduction, which can quickly conduct the heat inside the coil to the outside. The magnetic enhancer 13 divides the winding coil 11 into two sections and is arranged in the middle of the winding coil 11, so that the position where the magnetic enhancer 13 is arranged does not need to be arranged with the winding coil 11, and can provide larger magnetic force, which acts together with the magnetic yoke ring 14 to magnetically attract the magnetic action member in the pipeline, so that the magnetic action member moves horizontally in the pipeline. In addition, the magnetic enhancer 13 can approach any section of the framework 123, thereby enhancing the magnetic field strength of any end, so that the electromagnetic force generated by the corresponding end is stronger, so as to adapt to the needs of different ends requiring different electromagnetic forces.

[0112] The induction coil structure 1 is provided with at least two winding coils 11 (as shown in FIG. 8), the winding coils 11 are connected in parallel, the winding coils 11 are arranged in sections on the outer wall of the framework 123, the winding density of the winding coils 11 arranged at the two ends of the framework 123 is a first density, the winding density of the winding coils 11 arranged in the middle of the framework 123 is a second density, and the first density is greater than the second density. Among them, the winding coils 11 are arranged equidistantly or unequidistantly on the framework 123, and the current directions of any two winding coils 11 are the same or opposite.

[0113] It can be understood that the induction coil structure 1 is provided with at least two winding coils 11, that is, the winding coils 11 are arranged in sections, the winding density of the winding coils 11 arranged in the middle of the framework 123 is smaller than the winding density of the winding coils 11 arranged at the two ends of the framework 123, which can reduce the number of insulated conductor wires arranged on the winding coils 11 in the middle, reduce the use amount of insulated conductor wires arranged in the middle of the winding coils 11, reduce the cost of the whole induction coil structure 1, and reduce the power. Further, different current values of power can be input to each winding coil 11 respectively, so that the induction coil structure 1 can exert different electromagnetic forces on the corresponding sections, so as to cope with the situation of the size of the corresponding electromagnetic force, and better exert the corresponding electromagnetic force for fine driving control.

[0114] When the winding coil 11 is arranged in sections, the winding coils 11 are arranged equidistantly or unequidistantly on the framework 123, wherein the distance between the winding coils 11 can be set according to the electromagnetic force required by the actual corresponding position to adapt to the actual demand of the current position.

[0115] According to FIG. 16, the segmented coil large diameter curve and the segmented coil small diameter curve are the electromagnetic force simulation curves generated by the segmented coil of the present application, the traditional coil large diameter curve and the traditional coil small diameter curve are the electromagnetic force simulation curves generated by the traditional coil, and the above-mentioned curves are obtained under the condition that the stroke balance points are the same.

[0116] Specifically, the present application is a segmented coil, and the traditional coil, whether it is a large diameter coil or a small diameter coil, is a complete winding on the skeleton. Compared with the traditional coil, the segmented coil provides a larger initial acceleration for the magnetic action member in the pipeline, and the electromagnetic force generated by the segmented coil is larger than that of the traditional coil and faster in speed. Further, the segmented coil more effectively provides a larger electromagnetic force at the initial position, which can better reduce the risk of jamming of the magnetic action member in the pipeline. Further, as shown in the two traditional coil curves in FIG. 16, the traditional coil gradually decreases after reaching the maximum electromagnetic force, and a peak value appears. As shown in the two segmented coil curves in the figure, the inductive coil structure 1 in the present application can reach a first peak value of electromagnetic force and generate a second peak value in the subsequent period of time, that is, two peak values appear. The first peak value is the maximum electromagnetic force. In the electromagnetic force simulation curve of the segmented coil, compared with the electromagnetic force simulation curve of the traditional coil, the segmented coil can provide a larger electromagnetic force, and the electromagnetic force reaches the first peak value faster. The segmented coil responds faster, and due to the two peak values, the high electromagnetic force lasts longer and the stroke is longer.

[0117] In the present embodiment, the position detection of the magnetic action member uses the moving position of the piston, the piston moves synchronously with the magnetic action member, the piston provides driving force for the magnetic action member, and the segmented coil uses two winding coils. When the segmented coil uses more than two winding coils, the electromagnetic force simulation curve of the segmented coil can have more than two peak values. Correspondingly, the high value electromagnetic force lasts longer and the stroke is longer.

[0118] Wherein, as an embodiment, two winding coils 11 are arranged on the skeleton 123 (as shown in Figures 8-9), including a first winding coil 11a and a second winding coil 11b, the first winding coil 11a and the second winding coil 11b are arranged in sequence on the outer surface of the skeleton 123, the first winding coil 11a and the second winding coil 11b are arranged close to the two ends of the skeleton 123, when energized, AC power can be input, the AC power can change the current direction input to the first winding coil 11a and the second winding coil 11b within a certain time, through the current direction of the first winding coil 11a and the second winding coil 11b, the magnetic action member in the pipeline can change the moving direction. The first winding coil 11a and the second winding coil 11b are connected in parallel, the first winding coil 11a includes a first terminal 111 and a second terminal 112, the second winding 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.

[0119] In order to make the magnetic field strength generated by the two winding coils 11 larger, a magnetic enhancement member 13 can be arranged in the space between the first winding coil 11a and the second winding coil 11b, and the magnetic enhancement member 13 can increase the magnetic field strength generated between the first winding coil 11a and the second winding coil 11b.

[0120] When the electromagnetic force generated by any one of the first winding coil 11a or the second winding coil 11b needs to be larger, the magnetic enhancement member 13 can be arranged close to the corresponding winding coil 11, so as to increase the magnetic field strength of the corresponding winding coil 11, thereby enhancing the electromagnetic force generated by the winding coil 11. For example, the electromagnetic force generated at the position of the first winding coil 11a needs to be adjusted or increased, the magnetic enhancement member 13 can be arranged close to the first winding coil 11a, thereby increasing the electromagnetic force generated by the first winding coil 11a, and providing greater driving force.

[0121] The current direction input by the first winding coil 11a is opposite to the current direction input by the second winding coil 11b. Specifically, the first winding coil 11a and the second winding coil 11b are arranged at the two ends of the skeleton 123, and due to the different current directions input by the first winding coil 11a and the second winding coil 11b, 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 action member in the pipeline moves in different directions, and the magnetic action member can reciprocate in the pipeline.

[0122] Optionally, the first winding coil 11a and the second winding coil 11b can be inputted with direct current or alternating current. When the direct current is inputted, the winding directions of the first winding coil 11a and the second winding coil 11b are different, and the terminals of the winding coil 11 are connected in parallel, so that the electromagnetic force generated by the first winding coil 11a is opposite to the electromagnetic force generated by the second winding coil 11b after the input of the power supply. When the alternating current is inputted, the coil can be controlled by the diode arranged on the first contact sheet 16 and the second contact sheet 17, and the diodes are arranged in opposite directions, so that the power supply is inputted in the first winding coil 11a or the second winding coil 11b, thereby applying electromagnetic forces in different directions at both ends of the framework 123.

[0123] Optionally, in order to control the input current of the first winding coil 11a or the second winding coil 11b, an adjustable load can be arranged on the first contact sheet 16 and the second contact sheet 17, and the size of the input current can be changed by changing the size of the load.

[0124] Optionally, the framework 123 is provided with more than two winding coils 11, and the winding coils 11 are arranged in sections and can be equidistantly or unequidistantly arranged on the framework 123 to provide electromagnetic forces at corresponding positions. Optionally, the winding coils 11 can be evenly arranged at both ends of the framework 123 or equidistantly arranged along the framework 123.

[0125] Optionally, a magnetic enhancer 13 is arranged between adjacent winding coils 11. It can be understood that a plurality of winding coils 11 are arranged, and the number of the magnetic enhancers 13 is less than the number of the winding coils 11 by one. The winding coils 11 and the magnetic enhancers 13 are arranged on the framework 123, and the winding coils 11 are electrically connected. Compared with the winding coil arranged in a whole section on the framework 123, the winding coil arranged in multiple sections can save cost and reduce the amount of conductors with insulation layers. In addition, the winding coils 11 arranged in sections can be electrically controlled respectively, so that the direction and size of the electromagnetic force generated by each winding coil 11 are controllable.

[0126] The number of magnetic yoke rings 14 is increased corresponding to the number of winding coils 11, and is not limited to two magnetic yoke rings 14. A plurality of magnetic yoke rings 14 can be provided, so that the corresponding winding coils 11 can better conduct magnetism inside the skeleton 123 through the magnetic yoke ring 14, to ensure the magnetic field strength. The number of magnetic yoke rings 14 is set according to actual conditions. As an embodiment, the winding density of the insulated wire of the winding coil 11 and the length of the winding coil 11 are adjusted according to the actual size 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 winding coil 11 can be increased, so that a larger electromagnetic force can be generated under the same current value. Correspondingly, when a smaller electromagnetic force needs to be applied, the density of the insulated wire or the length of the winding coil 11 is correspondingly reduced.

[0127] As an embodiment, the power supply is initially input to the induction coil structure 1, the winding coil 11 in the middle of the skeleton 123 applies a preset first current value of the power supply, and after a preset third time period of applying the first current value of the power supply, the winding coil 11 in the middle of the skeleton 123 applies a preset second current value of the power supply. The first current value is greater than the second current value.

[0128] Specifically, when starting, a larger current value is applied to the winding coil 11, the winding coil 11 generates an electromagnetic force, and the magnetic action member installed inside the induction coil structure 1 generates a magnetic action force. After a period of time after starting, the current value of the applied power supply is reduced to a second current value, which can meet the situation that a larger driving force needs to be provided in the initial state at some specific positions. For example, when the magnetic action member is started, the inside of the pipeline cavity 200 where the magnetic action member is located is in a dry state, and the magnetic action member needs to overcome a larger resistance in the pipeline cavity 200, so the required driving force is larger than the driving force required under normal circumstances. Therefore, when starting, a larger current is required in the middle winding coil 11 to provide a larger driving force for the iron core 221, so that the iron core 221 starts.

[0129] As an embodiment, the current value input to the winding coil 11 arranged near the two ends of the skeleton 123 is smaller than the current value input to the winding coil 11 arranged in the middle of the skeleton 123. Specifically, the current value input to the two ends is smaller than the current value input to the middle, so that the electromagnetic force of the magnetic action member near the two ends of the pipeline decreases, and the speed of the magnetic action member moving to the two ends decreases, avoiding the magnetic action member quickly approaching the two ends of the pipeline, preventing the water hammer effect of the pipeline when transmitting liquid, and avoiding damage to the inner wall of the pipeline. At the same time, the current value in the middle can make the magnetic action member overcome the force generated by the spring at the two ends, so that the valve core 25 and other mechanisms can move normally.

[0130] The winding coil is connected to alternating current, and each winding coil can select corresponding connection of diode or no connection of diode, such as the winding coil at the port adopts no connection of diode, by connecting to alternating current, the magnetic action piece keeps still or slows down the motion state at the port; connection of diode can make the magnetic action piece gradually accelerate the moving speed; through specific needs, the setting of connection of diode or no connection of diode is adopted.

[0131] As an embodiment, the power supply connected to the winding coil 11 controls the current switching period through the timer or PWM signal, controls the output flow and pressure stability of the pump.

[0132] In a specific embodiment, the inductive coil structure 1 is externally connected with a current adjusting module to adjust the current size of the coil, thereby reducing energy waste.

[0133] In another specific embodiment, the inductive coil structure 1 is externally connected with a control module and a display screen, which are used for the operator to control and monitor the working state of the inductive coil structure 1, thereby improving the working efficiency and reducing the damage to the electromagnetic pump caused by operation errors.

[0134] As an embodiment, the inductive coil structure 1 comprises a rubber coating layer 15, which is coated on the outer surface of the winding coil 11. The rubber coating layer 15 protects the insulated wire of the winding coil 11 and also plays an insulating role when high voltage is connected.

[0135] Secondly, referring to Figs. 17-25, the electromagnetic pump of the present application comprises an induction coil structure 1 and a pump assembly 2, the pump assembly 2 is arranged in a skeleton 123, the pump assembly 2 is surrounded by a magnetic yoke 14, the magnetic induction coil structure 1 can provide driving force for the pump assembly 2, the pump assembly 2 is provided with a cavity 200, has a self-suction and pressure-increasing function, by exerting pressure on the fluid in the cavity 200, the output fluid can generate large pressure, thereby meeting the demand of outputting high-pressure fluid. Since the coil in the existing electromagnetic pump is a pure solenoid coil, more insulated wires are used, when working, the magnetic field is generated by the coil, and the magnetic circuit is formed by the external retainer 122 and the magnetic yoke 14, the magnetic field use efficiency of this way is low, and the temperature rise is high. If you want to reduce the temperature rise, you can increase the amount of wire used, but it will increase the production cost; or increase a static iron core 221 in the cylindrical pipe to improve the electromagnetic attraction and use efficiency, but this way will also increase the production cost, and when working, the static iron core 221 and the moving iron core 221 will attract each other and collide, which is easy to damage the protective layer of the two, causing rust and contaminating the medium. The induction coil structure 1 can well solve this problem, reduce the insulated wires in the middle, concentrate the insulated wires at both ends, thereby keeping the insulated wires with strong magnetic field at both poles, reducing the number of insulated wires with weak magnetic field, so as to reduce the cost, in addition, the reduction of the number of insulated wires can reduce the temperature rise.

[0136] The pump assembly 2 comprises a pipe body 21, a moving assembly 22, a reset assembly 23, a sealing assembly 24, a valve core 25 and a water outlet pipe 26; the pipe body 21 is arranged on the frame body 12; the moving assembly 22, the reset assembly 23 and the valve core 25 are movably arranged in the pipe body 21; the reset assembly 23 is in contact with the moving assembly 22; the moving assembly 22 is detachably connected with the valve core 25; the water outlet pipe 26 is arranged on one side of the pipe body 21; the sealing assembly 24 is arranged between the pipe body 21 and the water outlet pipe 26; the sealing assembly 24 comprises a sealing rubber head 241 arranged at the end of the valve core 25; the moving assembly 22, the sealing assembly 24, the valve core 25 and the water outlet pipe 26 form a sealed cavity 200 in the pipe body 21. When the induction coil structure is powered on, the moving assembly is driven by the magnetic force of the induction coil structure and presses the reset assembly in the pipe body, the pressure of the cavity is reduced to open the valve core; when the induction coil structure is powered off, the reset assembly is reset, the pressure of the cavity is increased to open the sealing rubber head and reciprocate to pump water. When the winding coil 11 is powered on, the moving assembly 22 is driven by the magnetic force of the magnetic yoke ring 14 and the magnetic intensifier 13 and presses the reset assembly 23 in the pipe body 21, at this time, the pressure of the cavity 200 is reduced to open the valve core 25; when the alternating current reaches the lower half cycle, the reset assembly 23 is reset, at this time, the pressure of the cavity 200 is increased to open the sealing rubber head 241 and reciprocate to pump water; during this period, the magnetic intensifier 13 enhances the magnetic force of the magnetic yoke ring 14.

[0137] It can be understood that, in operation, the winding coil 11 is powered on, at this time, the magnetic yoke ring 14 and the magnetic intensifier 13 generate a magnetic field together, the magnetic field is conducted to the moving assembly 22, at this time, the magnetic intensifier 13 enhances the magnetic force generated by the magnetic flux inside the winding coil 11; the moving assembly 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 assembly 22, the sealing assembly 24, the valve core 25 and the water outlet pipe 26 in the pipe body 21 becomes larger and the pressure becomes smaller, at this time, the valve core 25 is passively opened to balance the pressure in the cavity 200; the current used is alternating current, after passing through the diode, the current remains for half a cycle, therefore, in the process from power-on to power-off, the reset assembly 23 is reset after compression and deformation and pushes the moving assembly 22 out, so that the moving assembly 22 moves to the right, at the same time, the volume of the cavity 200 becomes smaller and the pressure becomes larger, so that the sealing rubber head 241 is opened to balance the pressure and reciprocate to pump water.

[0138] The induction coil structure 1 and the pump assembly 2 are detachably connected or fixedly connected, the retaining frame 122 is sleeved outside the skeleton 123, and the winding coil 11 is sleeved on the skeleton 123; the retaining frame 122 and the skeleton 123 are respectively provided with through holes, the pipe body 21 in the pump assembly 2 penetrates through the through holes of the retaining frame 122 and the skeleton 123, when it is necessary to replace parts, the pump assembly 2 is pulled out and replaced; in a specific embodiment, the frame body 12 is provided with a coupler 124 on one side, the coupler 124 and the retaining frame 122 are respectively provided with threaded holes, the through hole of the retaining frame 122 is aligned with the through hole of the skeleton 123, then the pipe body 21 is penetrated, then the coupler 124 is penetrated into the pipe body 21, then the threaded holes of the coupler 124 and the retaining frame 122 are screwed in turn by screws; in another specific embodiment, the coupler 124 and the retaining frame 122 are respectively provided with two threaded holes and are arranged in a diagonal line, then only two screws can realize assembly and fixation of 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 penetrated into the through holes of the retaining frame 122 and the skeleton 123, when it is necessary to replace parts, the pump assembly 2 is pulled out and replaced.

[0139] When the induction coil structure 1 is powered on, the magnetic force received by the moving assembly 22 is enhanced, and reciprocating motion is generated in the pipe body 21, which plays a role of pumping water; the magnetic field enhancer 13 not only can increase the electromagnetic attraction, but also greatly reduces the use amount of the insulated wire, reduces the cost, has smaller power and higher efficiency.

[0140] Specifically, the position of the magnetic field enhancer 13 can be set according to the use demand of the electromagnetic pump, when the electromagnetic pump needs to have larger pressure and flow, the magnetic field enhancer 14 can be arranged close to the corresponding magnetic yoke ring 14, so as to enhance the magnetic field strength around the magnetic yoke ring 14, to generate stronger electromagnetic force, to obtain larger pressure and flow, after the water pump of the electromagnetic pump 1 is used, the moving assembly 22 will stop moving due to larger resistance. In addition, the magnetic field enhancer 13 is arranged at the middle position between the adjacent two magnetic yoke rings 14, so that the electromagnetic force generated by the adjacent magnetic yoke rings 14 is more uniform.

[0141] As an embodiment, the rack body 12 is provided with a coupler 124 which can be connected to the pipe body 21 and fixed. The coupler 124 and the holder 122 are respectively provided with threaded holes. After the through hole of the holder 122 is aligned with the through hole of the skeleton 123, the pipe body 21 is inserted, the coupler 124 is inserted into the pipe body 21, and then the threaded holes of the coupler 124 and the holder 122 are screwed in sequence by screws. The pipe body 21 is limited by the coupler 124 and the holder 122, and the fluid enters the pipe body 21 from the coupler 124. In addition, the coupler 124 and the holder 122 are respectively provided with two threaded holes which are arranged in a diagonal line. Therefore, only two screws are needed to assemble and fix the pipe body 21 and the holder 122.

[0142] The reset assembly 23 includes a first elastic member 231, a second elastic member 232 and a third elastic member 233; the moving assembly 22 includes an iron core 221; the first elastic member 231, the second elastic member 232 and the iron core 221 are respectively movably arranged in the pipe body 21; the iron core 221 is arranged between the first elastic member 231 and the second elastic member 232; and the third elastic member 233 is movably arranged in the iron core 221 and detachably connected with the valve core 25.

[0143] In specific implementation, the first elastic member 231 and the second elastic member 232 are springs, and the third elastic member 233 is a tension spring; the moving assembly 22 includes the iron core 221 which is made of iron and can move in the pipe body 21 under the magnetic force. Specifically, after the winding coil 11 is powered, the iron core 221 moves to the left under the magnetic force of the magnetic yoke ring 14 and the magnetic member 13, the volume of the sealed cavity 200 formed by the moving assembly 22, the sealing assembly 24, the valve core 25 and the water outlet pipe 26 in the pipe body 21 becomes larger, the pressure becomes smaller, and the valve core 25 is passively opened to balance the pressure in the cavity 200; in the next period of the current, the first elastic member 231 resets, so that the iron core 221 moves to the right, the volume of the cavity 200 becomes smaller, the pressure becomes larger, and the sealing rubber head 241 is opened to pump out the liquid. The first elastic member 231 and the second elastic member 232 are arranged in the pipe body 21 and arranged on both sides of the iron core 221; the second elastic member 232 can buffer the iron core 221; after the winding coil 11 is powered, the magnetic yoke ring 14 generates a magnetic force, and moves in the pipe body 21 under the magnetic force; when the iron core 221 moves to the left, the first elastic member 231 is pressed and deformed; then the first elastic member 231 resets, the iron core 221 moves to the right and presses the second elastic member 232, and at this time, the second elastic member 232 buffers the iron core 221 to avoid large wear of the pipe body 21.

[0144] In addition, there is no fluid in the electromagnetic pump, and the iron core may be unable to move due to relatively large resistance after drying. By arranging a magnetism increasing member in the structure of the induction coil, the magnetic field strength can be increased, so that the electromagnetic force is stronger, and the iron core is more easily to overcome the resistance.

[0145] The iron core 221 is provided with a tapered hole 2211, and the valve core 25 is provided with a limiting block 251 corresponding to the tapered hole 2211. The limiting block 251 is arranged in the tapered hole 2211 and in contact with or away from the tapered hole 2211.

[0158] Please refer to FIG. 24 and FIG. 25, FIG. 24 is a coil without a magnetic member, and the coil wire diameter is 0.23 mm, and the weight is 150 g; from FIG. 24, it can be seen that the temperature rise of the coil at this time is 141.64547619. FIG. 24 is a coil with a magnetic member, and the coil wire diameter is 0.18 mm, and the weight is 80 g; from FIG. 25, it can be seen that the temperature rise of the coil at this time is 84.59421488. In summary, after the magnetic member 13 is added to the winding coil 11, the temperature rise of the winding coil 11 is much smaller than that when the magnetic member 13 is not added, and the flow rate change rate is small, which is more stable; it can be seen that the thermal conductivity of the magnetic member 13 is strong, which can conduct the heat inside the winding coil 11 to the outside, reducing the temperature rise; at the same time, the weight of the wire with an insulating layer used is small, which can greatly reduce the cost.

[0159] As an embodiment, for the control of the electromagnetic pump 100, the specific operation is as follows:

[0160] The winding coil 11 in the magnetic induction coil mechanism is energized, and the current value is configured according to the actual electromagnetic force required by the iron core 221 at the corresponding position of the winding coil 11; after the winding coil 11 is energized 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, and the movement direction of the iron core 221 is controlled.

[0161] Specifically, after the magnetic induction coil mechanism is installed on the pump assembly 2, before the electromagnetic pump 100 is running, the electromagnetic force required by the determined iron core 221 on the magnetic induction coil mechanism at different positions is calculated according to the electromagnetic force, the number of turns of the winding coil 11 and other parameters, and the current value corresponding to the input of the winding coil 11 is calculated, the electromagnetic force is accurately controlled according to the actual demand, different working conditions are adapted, and the adjustability of pump output flow and pressure is realized. The change of the magnetic field polarity is changed by using the current direction, so that the electromagnetic force changes with the change of the current direction, the electromagnetic force can drive the iron core 221 to make reciprocating motion in the pipe body 21, the electromagnetic force driving the iron core 221 can improve the response speed, and high-frequency operation can be realized. The winding coil 11 alternately changes the current direction, thereby controlling the movement direction of the iron core 221, so that the iron core 221 can realize reciprocating motion, thereby pumping high-pressure liquid, and continuously alternating, which can realize the continuous delivery of liquid.

[0162] It can be understood that by energizing the induction coil structure 1, an electromagnetic force can be provided for the iron core 221 to drive the iron core 221 to move. Since the iron core 221 needs different electromagnetic forces to drive at different positions of the pipeline, the winding coil 11 on the induction coil structure 1 needs to apply different current values, needs to be configured corresponding to different positions of the pipeline, and the electromagnetic pump 100 needs to be opened or closed, needs the iron core 221 to move in two different directions, by changing the direction of the current applied to the induction coil structure 1, thereby controlling the moving direction of the iron core 221, the electromagnetic pump 100 realizes the opening or closing action, uses the coil to increase the magnetic field to improve the conduction efficiency of the electromagnetic pump 100, alternately changes the direction of the current, and the electromagnetic force continuously alternates in direction. The iron core 221 in the pump assembly 2 continuously reciprocates to realize the liquid suction and liquid discharge process of the cavity 200 in the pump assembly 2. The pump assembly 2 can continuously output fluid, and the pump assembly 2 can efficiently and reliably operate. The movement of the iron core 221 is controlled by the electromagnetic force generated by the winding coil 11, which avoids directly driving the iron core 221 to move, and can reduce the energy consumption required by the pump assembly 2.

[0163] Further, the current values input by the winding coils 11 at different positions are different, which can generate different electromagnetic forces, and can be suitable for different electromagnetic force driving conditions at different positions, so that the speed and position of the iron core 221 movement are controllable. For example, near the water outlet and the water outlet, the speed of the iron core 221 can be gradually slowed down to prevent water hammer effect caused by the fast movement of the iron core 221.

[0164] As an embodiment, the winding coil 11 is connected to alternating current or direct current. When connected to alternating current, a diode can be connected to control the direction of current input, and when connected to direct current, direct current 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 realize reciprocating motion.

[0165] As an embodiment, the current value input by the winding coil 11 near the two ends of the pipeline is smaller than the current value input by the winding coil 11 in the middle of the pipeline. Specifically, the current value input at both ends is smaller than the current value in the middle, which can make the electromagnetic force near the two ends of the pipeline smaller, and the speed of the iron core 221 is reduced when moving to the two ends, avoiding fast approaching the two ends of the pipeline, and preventing water hammer effect; at the same time, the current value in the middle is large, which can make the iron core 221 overcome the force generated by the springs at both ends, so that the iron core 221 and the valve core 25 and other mechanisms can move normally.

[0166] As an embodiment, at the start, the winding coil 11 in the middle of the pipeline applies a preset first current value power supply; after a preset third time period after starting, the winding coil 11 in the middle of the pipeline applies a preset second current value power supply, and the first current value is greater than the second current value.

[0167] Specifically, when starting, a larger current value is applied to the iron core 221, and after a period of time after starting, the current value of the power supply applied to the iron core 221 is reduced to a second current value, which can meet the case where a larger driving force needs to be provided in the initial state in some specific positions, such as when the pump assembly 2 starts and the cavity 200 is in a dry state. The iron core 221 needs to overcome a larger resistance in the cavity 200, resulting in a larger driving force required than the driving force required under normal circumstances. Therefore, when starting, a larger current needs to be provided to the middle winding coil 11 to provide a larger driving force to the iron core 221, so that the iron core 221 starts.

[0168] As an embodiment, the power supply connected to the winding coil 11 controls the current switching period through a timer or a PWM signal to control the output flow and pressure stability of the pump.

[0169] As an embodiment, the winding coil 11 is provided in multiple segments, and the winding proportion of the winding coil 11 can be self-defined to make each segment generate different electromagnetic forces, so that various movements can be achieved.

[0170] In a third aspect, the present application provides an electromagnetic valve, which comprises the above-mentioned induction coil structure 1 and a pipeline. The electromagnetic valve is used to control the inflow and outflow of fluid in the pipeline. Since the existing valve opening speed or closing speed is too fast, water hammer effect is easy to occur, which causes damage to the pipeline where the existing valve is located. In order to solve the damage caused by water hammer effect, the existing technology usually uses proportional valve, PWM adjustment and other methods to adjust the valve. The induction coil structure 1 is arranged on the electromagnetic valve, and is arranged in segments on the pipeline of the valve to control different electromagnetic forces generated by each segment, so that the opening amplitude of the valve core 25 of the electromagnetic valve is adjusted, and the opening speed or closing speed of the electromagnetic valve has a gradual change process. For example, when opening, the opening speed of the electromagnetic valve gradually increases, and when closing, the opening speed gradually decreases, so as to avoid the water hammer effect of the fluid in the pipeline, prevent the pipeline and equipment connected to the electromagnetic valve from being damaged by the force caused by the water hammer effect, and prolong the service life of the equipment.

[0171] In a fourth aspect, the present application provides an electromagnetic fluid pump, which comprises the above-mentioned induction coil structure 1 and a pipeline. The induction coil structure 1 is arranged outside the pipeline, and generates a magnetic field after being energized.

[0172] Specifically, the fluid with electrical conductivity flows in the pipeline, after the induction coil structure 1 is powered on, the fluid in the pipeline generates electromagnetic force under the action of the magnetic field, the electromagnetic force can provide driving force for the fluid in the pipeline, so that the fluid flows in the pipeline along the direction of the electromagnetic force, the electromagnetic fluid pump can save the design of the driving assembly and the pump assembly in the electromagnetic pump, the electromagnetic fluid pump structure is light in weight, and the production cost of the electromagnetic fluid pump is reduced. In addition, the fluid with electrical conductivity can corrode the pump assembly, and the pump body can avoid the corrosion of the fluid to the pump assembly, thereby prolonging the service life of the electromagnetic fluid pump.

[0173] As an embodiment, a plurality of coils are arranged in the induction coil structure 1, and are arranged in sections, which can increase the magnetic field. The arrangement of the multiple section coils can make the liquid metal respond faster, flow faster and stop faster, so as to meet the requirement of fast response of the device and ensure the stability of the device.
