[0002] Application Number: 2024111418908

[0003] Application Date: August 20, 2024 Application Title: An Infrared Pot Detection Driving Method, Coil Device, Control Device, and Storage Medium

[0004] The case Technical Field

[0005] This invention relates to the field of computer control technology, and in particular to an electromagnetic heating power adjustment method and coil device, control device, and storage medium. Background Technology

[0006] Existing electromagnetic coil heating devices have a large-area support panel on the shell, which can hold multiple pots. For user convenience, multiple electromagnetic modules are installed inside the shell, arranged horizontally. When driven, the electromagnetic modules generate a magnetic field. To ensure a wider and more uniform magnetic field distribution area in the horizontal direction, the diameter of the electromagnetic coils in the electromagnetic modules is limited to a small range. A pot may cover multiple electromagnetic modules. The control module controls the covered electromagnetic modules to start running, so that multiple magnetic fields act on the pot, optimizing the heating effect on the pot.

[0007] However, in practical use, since some electromagnetic modules are only partially covered by the pot body, the covered area may be less than half or even smaller. If the control module still drives this electromagnetic module, it will increase the power load and power consumption, even when the heating effect is not obvious. Therefore, in the past, a pressure detection diaphragm or capacitive sensor was installed on the support panel. After the pot body is placed on the support panel, the pressure detection diaphragm or capacitive sensor can detect the position of the pot body and control the operation of the corresponding electromagnetic module according to the position covered by the pot body. However, during the operation of the electromagnetic module, the pressure detection diaphragm or capacitive sensor is easily affected by magnetic field interference, which will cause the detection results to deviate. This may cause the control module to malfunction in subsequent control of the electromagnetic module. Therefore, some manufacturers are considering replacing the pressure detection diaphragm or capacitive sensor with an infrared transceiver probe. The infrared transceiver emits infrared light. If a pot is located above the transceiver, the infrared light will be reflected and received again by the transceiver, indicating that the area where the transceiver is located is covered by the pot. The transceiver is not easily affected by magnetic field interference. However, as the detection principle of the transceiver shows, unlike the planar detection range of pressure detection membranes or capacitive sensors, the detection range of the transceiver on a horizontal plane is only a point. Therefore, the solution using the transceiver is basically to compensate for the limitation of the transceiver only being able to detect points by increasing the number of transceivers. Arranging more transceivers on the horizontal plane of the electromagnetic coil device can improve the detection accuracy, but this also means that the manufacturing cost and processing difficulty will increase significantly, and the production efficiency will decrease accordingly. Summary of the Invention

[0008] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an electromagnetic heating power adjustment method and a coil device, control device, storage medium, infrared detection, and a reasonable pot detection logic to drive the operation of the electromagnetic coil. This eliminates the need for excessive infrared detection components, reduces power consumption, lowers the manufacturing cost and processing difficulty of the coil device, and improves production efficiency while meeting heating requirements.

[0009] According to a first aspect of the present invention, an electromagnetic heating power adjustment method is applied to an electromagnetic coil device. The electromagnetic coil device includes multiple electromagnetic modules, which are uniformly distributed horizontally and have a supporting surface for supporting a pot body formed on them. Each electromagnetic module includes an infrared detection module, a first electromagnetic coil, and at least one second electromagnetic coil sequentially nested within the first electromagnetic coil from the inside out. The infrared detection module includes multiple sets of infrared detection components, which are correspondingly arranged between adjacent first and second electromagnetic coils or between two second electromagnetic coils. Each set of... The infrared detection component includes at least three infrared transceivers, and the infrared transceivers are evenly distributed around the center of the electromagnetic module. The infrared transceivers are used to detect and output a pot detection signal, which indicates whether a pot exists above the infrared transceiver. Each electromagnetic module executes an electromagnetic heating power adjustment method, which includes: acquiring a power target value and the pot detection signals of each infrared transceiver, wherein the power target value is obtained according to the user's operation instructions; performing a first judgment step on the first electromagnetic coil, in which the pot detection signals of all infrared transceivers in the infrared detection component closest to the outer periphery of the first electromagnetic coil are judged, and when the pot detection signals are obtained... All pot detection signals indicate the presence of a pot. The target power value is used as the operating power value to drive the first electromagnetic coil. If not all pot detection signals indicate the presence of a pot, the first electromagnetic coil does not need to be driven. The second judgment step is performed sequentially on each of the second electromagnetic coils from the inside out. In the second judgment step, the pot detection signals of all infrared transceivers in the infrared detection assembly closest to the inner periphery of the second electromagnetic coil are judged. If all pot detection signals indicate the presence of a pot, the pot detection signals of all infrared transceivers in the infrared detection assembly closest to the outer periphery of the second electromagnetic coil are judged. The number of pots with pot detection signals indicating the presence of a pot is counted. If the number of pots meets the first driving condition, the power target value is corrected using the number of pots to obtain a power correction value, which is then used as the operating power value to drive the second electromagnetic coil. If the number of pots does not meet the first driving condition, the second electromagnetic coil is not driven. The operation of the first and second electromagnetic coils is controlled according to the results of the first and second judgment steps. In the second judgment step, the first driving condition includes a first proportion threshold. If the ratio of the number of pots to the total number of infrared transceivers in the infrared detection component closest to the outer periphery of the second electromagnetic coil is greater than the first proportion threshold, then the number of pots meets the first driving condition.

[0010] The electromagnetic heating power regulation method according to embodiments of the present invention has at least the following beneficial effects:

[0011] The electromagnetic heating power adjustment method of this invention first acquires the user-inputted power target value and the pot detection signals of each infrared transceiver before controlling the operation of the electromagnetic coil device. For each electromagnetic module, the electromagnetic heating power adjustment method is performed for self-testing. Specifically, a first judgment step is performed on the first electromagnetic coil located at the center of the electromagnetic module, judging the pot detection signals of all infrared transceivers in the infrared detection assembly closest to the outer periphery of the first electromagnetic coil. If all pot detection signals indicate the presence of a pot above, it proves that the pot basically completely covers the first electromagnetic coil. Therefore, the power target value can be used as the basis for judgment. The operating power value for driving the first electromagnetic coil is used. If not all pot detection signals indicate the presence of a pot, it can be roughly determined that the pot covers less than half of the electromagnetic module, thus saving energy by not driving the first electromagnetic coil. In the process of judging the second electromagnetic coil, the second judgment step is performed sequentially from the inside out. Utilizing the characteristic that the inner diameter of the second electromagnetic coil is always shorter than its outer diameter, the pot detection signals of all infrared transceivers in the infrared detection assembly closest to the inner circumference of the second electromagnetic coil are judged first. When all pot detection signals... The presence of a pot above the second electromagnetic coil indicates that the pot covers most of the area of ​​the second electromagnetic coil. At this point, the detection signals from all infrared transceivers in the infrared detection components closest to the outer periphery of the second electromagnetic coil are analyzed. The number of pots detected by these signals is counted. If the number of pots meets the first driving condition, the power target value is corrected using this value to obtain a power correction value. This power correction value is then used as the operating power to drive the second electromagnetic coil. Since some infrared transceivers on the outer periphery of the second electromagnetic coil are not covered, it indicates that the second electromagnetic coil is not completely covered. Therefore, the driving power for the second electromagnetic coil can be appropriately adjusted. This ensures reasonable heating while saving energy and optimizing the heating effect. Finally, the operation of the first and second electromagnetic coils is controlled according to the results of the first and second judgment steps. This design uses infrared detection and a reasonable pot detection logic to drive the electromagnetic coil, eliminating the need for excessive infrared detection components. While meeting heating requirements, it reduces energy consumption, lowers the manufacturing cost and processing difficulty of the coil equipment, and improves production efficiency.

[0012] According to some embodiments of the present invention, if not all pot detection signals in the first judgment step indicate that a pot is present above, then the second judgment step is not performed. Furthermore, when performing the second judgment steps sequentially, if in any second judgment step it is determined that not all pot detection signals in the infrared detection component closest to the inner periphery of the second electromagnetic coil indicate that a pot is present above, then the subsequent second judgment steps are not performed.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0029] like Figure 1 - Figure 8 As shown, the electromagnetic heating power adjustment method according to a first aspect embodiment of the present invention is applied to an electromagnetic coil device. The electromagnetic coil device includes a plurality of electromagnetic modules 100, which are uniformly distributed in a horizontal direction and have a bearing surface for supporting a pot body 300 formed on them. Each electromagnetic module 100 includes an infrared detection module, a first electromagnetic coil 120, and at least one second electromagnetic coil 130 sequentially sleeved on the first electromagnetic coil 120 from the inside to the outside. The infrared detection module includes a plurality of infrared detection components 110, which are arranged one-to-one between adjacent first electromagnetic coils 120 and second electromagnetic coils 130 or between two second electromagnetic coils 130. Each group of infrared detection components 110 includes at least three infrared transceivers 111, and the plurality of infrared transceivers 111 are uniformly distributed around the center of the electromagnetic module 100. The infrared transceivers 111 are used to detect and output a pot detection signal, which is used to characterize whether a pot body 300 is above the infrared transceiver 111.

[0030] Among them, such as Figure 3As shown, both the first electromagnetic coil 120 and the second electromagnetic coil 130 can be made of metals or alloys such as copper and tin. The first electromagnetic coil 120 and the second electromagnetic coil 130 can be wound into circular, elliptical, rectangular, hexagonal, or other polygonal shapes. Specifically, the number of second electromagnetic coils 130 surrounding the first electromagnetic coil 120 can be two or three. The infrared transceiver 111 of the infrared detection assembly 110, located closest to the outer periphery of the first electromagnetic coil 120, generally uses three, but can also use four. To reduce production costs, it is usually limited to no more than four. The number of infrared transceiver 111 in the infrared detection assembly 110 from the inside out... The number of infrared transceivers 111 can be the same as that of the infrared detection component 110 located closest to the outer periphery of the first electromagnetic coil 120. Alternatively, in some embodiments of the present invention, in the same electromagnetic module 100, the number of infrared transceivers 111 in the infrared detection component 110 gradually increases from the inside to the outside, and the number of infrared transceivers 111 in two adjacent infrared detection components 110 increases by one. That is, from the inside to the outside, the number of infrared transceivers 111 in the infrared detection component 110 gradually increases by one. Without excessively increasing production costs, the number of infrared transceivers 111 is moderately increased in conjunction with the increase in the perimeter of the electromagnetic coil, while ensuring the accuracy of pot detection.

[0031] A gap exists between the first electromagnetic coil 120 and the second electromagnetic coil 130, or between the second electromagnetic coil 130 and the second electromagnetic coil 130, to facilitate the placement of the infrared transceiver 111. The infrared transceiver 111 can employ an integrated infrared transceiver probe chip. The infrared transceiver probe chip can be integrated and housed in a metal or alloy casing to ensure magnetic field shielding. A light-transmitting panel is used on the front side to connect to the casing for a sealed installation. Infrared rays can be emitted from the light-transmitting panel. Figure 1 As shown, if there is a pot body 300 above the infrared transceiver 111, the infrared light will be reflected and received again by the infrared transceiver 111, thus it can be known that the area where the infrared transceiver 111 is located is covered by the pot body 300.

[0032] Each electromagnetic module 100 employs an electromagnetic heating power regulation method, such as... Figure 6 As shown, the electromagnetic heating power adjustment method includes:

[0033] S410: Acquire the target power value and the detection signals of each infrared transceiver 111;

[0034] S420. Perform a first judgment step on the first electromagnetic coil 120. In the first judgment step, judge the pot detection signals of all infrared receivers 111 in the infrared detection component 110 closest to the outer periphery of the first electromagnetic coil 120. When all pot detection signals indicate that there is a pot body 300 above, use the power target value as the working power value to drive the first electromagnetic coil 120 to run.

[0035] S430. The second judgment step is performed on each of the second electromagnetic coils 130 from the inside out. In the second judgment step, the pot detection signals of all infrared transceivers 111 in the infrared detection component 110 closest to the inner periphery of the second electromagnetic coil 130 are judged. When all pot detection signals indicate that there is a pot body 300 above, the pot detection signals of all infrared transceivers 111 in the infrared detection component 110 closest to the outer periphery of the second electromagnetic coil 130 are judged. The number of pots stored is counted, indicating that there is a pot body 300 above. When the number of pots stored meets the first driving condition, the power target value is corrected by the number of pots stored to obtain the power correction value. The power correction value is used as the working power value to drive the second electromagnetic coil 130 to run. When the number of pots stored does not meet the first driving condition, the second electromagnetic coil 130 is not driven to run.

[0036] S440. Control the operation of the first electromagnetic coil 120 and the second electromagnetic coil 130 according to the results of the first judgment step and each of the second judgment steps.

[0037] In the second judgment step, the first driving condition includes a first proportion threshold. When the ratio of the number of pots stored to the total number of infrared receivers 111 in the infrared detection component 110 closest to the outer periphery of the second electromagnetic coil 130 is greater than the first proportion threshold, the number of pots stored satisfies the first driving condition.

[0038] It is understandable that the power target value can be obtained based on the user's operation instructions. For example, if the user sets the required heating power to 2000W through buttons, potentiometer knobs, touch screens, etc., then the power target value is 2000W.

[0039] The electromagnetic heating power adjustment method of this invention first acquires the user-inputted power target value and the pot detection signals of each infrared transceiver 111 before controlling the operation of the electromagnetic coil device. For each electromagnetic module 100, the electromagnetic heating power adjustment method is performed for self-testing. Specifically, a first judgment step is performed on the first electromagnetic coil 120 located at the center of the electromagnetic module 100, judging the pot detection signals of all infrared transceivers 111 in the infrared detection components 110 closest to the outer periphery of the first electromagnetic coil 120. When all pot detection signals indicate the presence of a pot body 300 above, it proves that the pot body 300 essentially completely covers the first electromagnetic coil 120. Therefore, the power target value can be used as the driving force for the first electromagnetic coil 120. The operating power value of the first electromagnetic coil 120 is determined by the fact that not all pot detection signals indicate the presence of the pot body 300 above. This suggests that the pot body 300 does not cover half of the electromagnetic module 100, thus saving energy by not driving the first electromagnetic coil 120. Furthermore, it is unnecessary to check the individual second electromagnetic coils 130 located around the first electromagnetic coil 120. During the checking of the second electromagnetic coils 130, the second checking step is performed sequentially from the inside out. Utilizing the characteristic that the inner diameter of the second electromagnetic coil 130 is always shorter than its outer diameter, the infrared detection component 1 closest to the inner diameter of the second electromagnetic coil 130 is checked first. The detection signals of all infrared transceivers 111 in the second electromagnetic coil 130 are judged. When all detection signals indicate that a pot body 300 is present above, it can be roughly proven that the pot body 300 covers most of the area of ​​the second electromagnetic coil 130. At this time, the detection signals of all infrared transceivers 111 in the infrared detection components 110 closest to the outer periphery of the second electromagnetic coil 130 are judged, and the number of pots present with the detection signals indicating that a pot body 300 is present above is counted. When the number of pots present meets the first driving condition, the power target value is corrected using the number of pots present to obtain a power correction value. The power correction value is used as the working power value to drive the second electromagnetic coil 130. Here, since there is a portion located in the second electromagnetic coil 130, the power correction value is used to determine the working power value. The fact that the infrared transmitter 111 around the outer periphery of the electromagnetic coil 130 is not covered proves that the second electromagnetic coil 130 is also not completely covered. At this time, the driving power of the second electromagnetic coil 130 can be appropriately adjusted to save energy and optimize the heating effect while ensuring reasonable heating requirements are met. Finally, the operation of the first electromagnetic coil 120 and the second electromagnetic coil 130 is controlled according to the results of the first judgment step and each of the second judgment steps. This design uses infrared detection and reasonable pot detection logic to drive the operation of the electromagnetic coils, eliminating the need for too many infrared detection components. While meeting heating requirements, it reduces energy consumption, lowers the manufacturing cost and processing difficulty of the coil equipment, and improves production efficiency.

[0040] In some embodiments of the present invention, if not all pot detection signals in the first judgment step indicate that a pot body 300 is present above, then the second judgment step is not performed. Furthermore, when performing the second judgment steps sequentially, if in any second judgment step it is determined that not all pot detection signals in the infrared detection component 110 closest to the inner periphery of the second electromagnetic coil 130 indicate that a pot body 300 is present above, then the subsequent second judgment steps are not performed.

[0041] If the number of pots does not meet the first driving condition, the second electromagnetic coil 130 will not be driven to save power. In addition, when performing the second judgment step in sequence, if in any second judgment step it is determined that not all pot detection signals in the infrared detection component 110 closest to the inner periphery of the second electromagnetic coil 130 indicate that there is a pot body 300 above, the subsequent second judgment step will not be performed.

[0042] Since the infrared transceivers 111 in the infrared detection component 110 are all evenly arranged around the second electromagnetic coil 130, by calculating the ratio of the number of pots to the total number of infrared transceivers 111 in the infrared detection component 110 closest to the outer periphery of the second electromagnetic coil 130, the area covered by the pot body 300 to the second electromagnetic coil 130 can be roughly reflected. When the ratio is greater than the first percentage threshold, it proves that the pot body 300 covers a large area of ​​the second electromagnetic coil 130, and the second electromagnetic coil 130 can be driven at this time. Specifically, the first percentage threshold can be set between 80% and 100%, or it can be set according to the total number of infrared transceivers 111 in the infrared detection component 110. For example, if the total number of infrared transceivers 111 in the infrared detection component 110 is N, the first percentage threshold is N-1 / N or N-2 / N, etc.

[0043] In some embodiments of the present invention, such as Figure 7 As shown, the process of correcting the power target value using the number of stored pots to obtain the power correction value includes:

[0044] S510, Calculate the ratio of the number of stored pots to the total number of infrared transmitters and receivers 111 in the infrared detection assembly 110;

[0045] S520. The power correction value is obtained by multiplying the ratio and the power target value.

[0046] The ratio of the number of pots stored to the total number of infrared transmitters and receivers 111 in the infrared detection component 110 can roughly reflect the area of ​​the pot body 300 covering the second electromagnetic coil 130. At this time, the working power value of the second electromagnetic coil 130 can be reduced. Based on the area of ​​the pot body 300 covering the second electromagnetic coil 130, the larger the coverage area, the greater the impact of the second electromagnetic coil 130 on the heating of the pot body 300 when driven, so a larger working power can be applied to drive the second electromagnetic coil 130. Conversely, the smaller the coverage area, the smaller the impact of the second electromagnetic coil 130 on the heating of the pot body 300 when driven, so a smaller working power can be applied to drive the second electromagnetic coil 130. Thus, while meeting certain heating requirements, energy is saved. Therefore, by multiplying the ratio and the target power value to obtain the power correction value, and then using the power correction value as the working power, the above effect can be achieved.

[0047] like Figure 5 As shown, since multiple pots 300 can be placed simultaneously on the electromagnetic coil device, when two or more pots 300 cover the same electromagnetic module 100, it is possible that the condition that all pot detection signals in the same infrared detection component 110 indicate the presence of a pot 300 may not be met in the first and second judgment steps. This results in the first electromagnetic coil 120 and the second electromagnetic coil 130 not being driven in this situation. However, since multiple pots 300 cover the same electromagnetic module 100 and share a large area, even if the electromagnetic coils in the electromagnetic module 100 are driven, it will not cause excessive energy waste. Therefore, in some embodiments of the present invention, before controlling the operation of the first electromagnetic coil 120 and the second electromagnetic coil 130 according to the results of the first and second judgment steps, the following is also included:

[0048] The second electromagnetic coil 130 is checked one by one from the inside out. In the check step, the detection signals of all infrared transceivers 111 in the infrared detection component 110 closest to the inner periphery of the second electromagnetic coil 130 are judged and the first quantity value of the detection signal indicating that there is a pot body 300 above is counted. The detection signals of all infrared transceivers 111 in the infrared detection component 110 closest to the outer periphery of the second electromagnetic coil 130 are judged and the second quantity value of the detection signal indicating that there is a pot body 300 above is counted. When the second quantity value is greater than the first quantity value and the second quantity value meets the second driving condition, the first electromagnetic coil 120 and all the second electromagnetic coils 130 in the electromagnetic module 100 are driven to operate with the power target value as the working power value.

[0049] In the verification step, when the second quantity value is greater than the first quantity value, it can be proven that at least two pots 300 cover the electromagnetic module 100. At this time, it is determined whether the second quantity value meets the second driving condition. If it does, it can be proven that multiple pots 300 cover a large area on the electromagnetic module 100. At this time, the first electromagnetic coil 120 and the second electromagnetic coil 130 on the electromagnetic module 100 are both driven to run.

[0050] In some embodiments of the present invention, the second driving condition includes a second proportion threshold. When the ratio of the second quantity value to the total quantity value of the infrared transceivers 111 in the infrared detection assembly 110 closest to the outer periphery of the second electromagnetic coil 130 is greater than the second proportion threshold, the quantity value of the stored pots satisfies the second driving condition.

[0051] The second percentage threshold can be set between 80% and 100%, or it can be set according to the total number of infrared transceivers 111 in the infrared detection component 110. For example, if the total number of infrared transceivers 111 in the infrared detection component 110 is N, the second percentage threshold can be N-1 / N or N-2 / N, etc.

[0052] According to a second aspect embodiment of the coil disk device, such as Figure 1 - Figure 8 As shown, the system includes multiple electromagnetic modules 100 and a control module 210. The electromagnetic modules 100 are evenly distributed horizontally, and a supporting surface for supporting the pot body 300 is formed on each of the multiple electromagnetic modules 100. Each electromagnetic module 100 includes an infrared detection module, a first electromagnetic coil 120, and at least one second electromagnetic coil 130 sequentially sleeved on the first electromagnetic coil 120 from the inside out. The infrared detection module includes multiple sets of infrared detection components 110, which are correspondingly arranged between adjacent first electromagnetic coils 120 and second electromagnetic coils 130. Between one or two of the second electromagnetic coils 130, each group of infrared detection components 110 includes at least three infrared transceivers 111 and the plurality of infrared transceivers 111 are evenly distributed around the center of the electromagnetic module 100. The infrared transceivers 111 are used to detect and output a pot detection signal. The pot detection signal is used to characterize whether there is a pot body 300 above the infrared transceiver 111. The control module 210 is connected to each of the infrared transceivers 111 to execute the electromagnetic heating power adjustment method disclosed in any of the above embodiments and control the operation of each first electromagnetic coil 120 and each second electromagnetic coil 130.

[0053] The control module 210 may include an MCU or a CPU and its associated circuits. The structure of the electromagnetic module 100 is roughly the same as the structure of the electromagnetic heating power regulation method described above, and will not be described in detail here.

[0054] The coil device of the present invention, the control module 210 executes the electromagnetic heating power adjustment method disclosed in any of the above embodiments to control the operation of each first electromagnetic coil 120 and each second electromagnetic coil 130, infrared detection and reasonable pot detection logic drive the operation of electromagnetic coils, without the need to configure too many infrared detection components, while meeting the heating requirements, reducing power consumption, reducing the manufacturing cost and processing difficulty of the coil device, and improving production efficiency.

[0055] In some embodiments of the present invention, in the same electromagnetic module 100, the number of infrared transceivers 111 in the infrared detection components 110 gradually increases from the inside to the outside, and the number of infrared transceivers 111 in two adjacent infrared detection components 110 increases by one. That is, from the inside to the outside, the number of infrared transceivers 111 in the infrared detection components 110 gradually increases by one. Without excessively increasing the production cost, the number of infrared transceivers 111 is moderately increased in conjunction with the increase in the circumference of the electromagnetic coil, and the accuracy of pot detection is ensured.

[0056] In some embodiments of the present invention, each electromagnetic module 100 further includes a drive module, the drive module including a plurality of switch drive units 220, each switch drive unit 220 being connected one-to-one with the first electromagnetic coil 120 and each second electromagnetic coil 130 to form at least a portion of each drive branch, and the control module 210 being connected to each of the switch drive units 220 to control the operation of each first electromagnetic coil 120 and each second electromagnetic coil 130.

[0057] like Figure 8As shown, the switch driving unit 220 may include semiconductor switching transistors Q1, Q2, Q3, and Q4. The control module 210 controls switching transistors Q1 and Q4 to be turned on, and switching transistors Q2 and Q3 to be turned off. A first current flows through the first electromagnetic coil 120 or the second electromagnetic coil 130. The control module 210 controls switching transistors Q2 and Q3 to be turned on, and switching transistors Q1 and Q4 to be turned off. A second current flows through the first electromagnetic coil 120 or the second electromagnetic coil 130. The first and second currents are in opposite directions. Additionally, the control module 210... When all four control transistors Q1, Q2, Q3, and Q4 are turned off, no current flows through the first electromagnetic coil 120 or the second electromagnetic coil 130. The control module 210 drives the first electromagnetic coil 120 or the second electromagnetic coil 130 to switch between the above three states according to the magnitude of the working power value. For example, if the working power value is large, the duration of the turn-off of all four control transistors Q1, Q2, Q3, and Q4 is shortened, and the working power is increased accordingly. If the working power value is small, the duration of the turn-off of all four control transistors Q1, Q2, Q3, and Q4 is extended, and the working power is decreased accordingly.
