Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] refer to Figures 1 to 3 , a portable magnetic field control device, comprising:

[0044] A power module, used to provide power to the entire device;

[0045] A voltage regulating module is used to receive the voltage from the power module and boost it to the required operating voltage;

[0046] The control module is used to analyze the information of the operation buttons, receive and process the feedback signals, generate control signals, and send the information to the display module to display the corresponding information;

[0048] The magnetic field generating module is used to receive the voltage input from the control module and generate a corresponding magnetic field;

[0049] The user interaction module is used to adjust the output voltage setting value by operating the buttons, thereby changing the magnetic field strength and frequency.

[0050] In this embodiment, the device integrates all necessary functional modules, is compact and easy to carry, allowing users to use it flexibly in various environments and scenarios. Through the cooperation of the power module and the voltage regulation module, it is ensured that the device can stably and efficiently receive and convert electrical energy, and provide the required operating voltage for the magnetic field generating module. This not only improves the utilization efficiency of electrical energy, but also extends the continuous working time of the device and reduces energy waste. The control module can accurately analyze the information input by the user through the operation buttons and generate precise control signals based on this information, thereby achieving fine adjustment of the magnetic field strength and frequency. The display module displays key parameter information such as the frequency adjustment coefficient and output voltage in real time, allowing the user to intuitively understand the current working status of the device and facilitate monitoring and adjustment. This design improves the user experience and reduces the difficulty of operation. The user interaction module allows the user to easily set the output voltage value through simple and clear operation buttons, thereby changing the magnetic field strength and frequency. This design fully takes into account the user's usage habits and needs, making the device easier to operate and maintain.

[0051] It should be noted that the power module is composed of a rechargeable lithium battery that can provide a voltage of 12V. The specifications are 115*57*17mm and the capacity is 9800mAh. The remaining power can be displayed on the side. It is used to provide power for the device and can be charged to ensure the endurance of the device and enhance the convenience of the device.

[0052] The voltage regulating module is composed of a booster, which is used to boost the 12V voltage provided by the power supply to 24V, ensuring that the voltage can be flexibly adjusted according to different treatments and provide the required stable voltage;

[0053] The display module is composed of a display screen and is used to display parameters such as frequency adjustment coefficient and output voltage.

[0054] Preferably, the control module includes:

[0055] The single chip microcomputer is used to analyze the information of the operation buttons, generate control signals to control the drive circuit, and send the information to the display module to display the corresponding information;

[0056] A driving circuit, used for converting an input signal into an output voltage required for the operation of the magnetic field generating module;

[0057] H-bridge circuit, used to change the direction of current and thus change the polarity of the output voltage;

[0058] Filter, used to smooth the output voltage;

[0059] An output sampling circuit is used to sample the output voltage and feed the sampling signal back to the closed-loop feedback signal conditioning circuit;

[0060] The closed-loop feedback signal conditioning circuit is used to condition the output voltage according to the sampling signal.

[0061] In this embodiment, the introduction of the single-chip microcomputer enables the control module to have powerful data processing and logical judgment capabilities, and can efficiently analyze the information of the operation buttons and quickly generate corresponding control signals, which not only improves the response speed of the entire device, but also makes the device more intelligent; the drive circuit accurately converts the input signal into the working voltage required by the magnetic field generating module, ensuring the stability and accuracy of the voltage; the existence of the H-bridge circuit enables the control module to easily change the direction of the current, thereby changing the polarity of the output voltage; the filter smoothes the output voltage, effectively eliminating voltage fluctuations and noise, and improving the quality of the output voltage; the output sampling circuit and the closed-loop feedback signal conditioning circuit together constitute a closed-loop control system, which can automatically adjust the output voltage by continuously sampling the output voltage and comparing it with the expected value to ensure that it always remains within the set range. This closed-loop control strategy greatly improves the stability and accuracy of the output voltage.

[0062] It should be noted that the microcontroller receives information input by the user through the operation buttons and generates control signals accordingly. These signals are processed by the drive circuit and H-bridge circuit, and smoothed by the filter, and finally output a stable voltage. The output sampling circuit samples the output voltage and feeds the sampling signal back to the closed-loop feedback signal conditioning circuit. This feedback mechanism ensures the stability and accuracy of the output voltage.

[0063] Preferably, the output sampling circuit includes:

[0064] A sample-and-hold circuit, used to sample the output voltage at a preset time point;

[0065] The sampling control circuit is used to control the time point at which the sample-hold circuit performs a sampling operation.

[0066] In this embodiment, the sample-and-hold circuit can accurately sample the output voltage at a preset time point to ensure the accuracy and representativeness of the sampled value. At the sampling moment, the value of the analog signal is continuously changing, and the function of the sample-and-hold circuit is to "freeze" and hold the value of the analog signal at the sampling moment, so that the subsequent circuit can stably perform signal processing and conversion, avoiding the influence of signal fluctuations on the sampling results. The sample-and-hold circuit helps to isolate the sampling stage and the subsequent processing stage. Therefore, the signal captured at the sampling moment will not be affected by interference from the subsequent circuit, thereby improving the anti-interference capability of the entire circuit; the sampling control circuit can accurately control the time point when the sample-and-hold circuit performs the sampling operation, so that the sampling operation can be flexibly adjusted according to actual needs. By accurately controlling the sampling time point, the sampling control circuit can ensure that the sampling operation is performed at the moment when the signal is most stable and representative, thereby improving sampling accuracy and reliability.

[0067] Preferably, the closed-loop feedback signal conditioning circuit includes:

[0068] A sensor, configured to convert the detected sampling signal into an electrical signal;

[0069] A comparator, used to compare the signal output by the sensor with a reference voltage;

[0070] The feedback path circuit is used to feed the output voltage signal back to the input terminal to form a closed-loop control.

[0071] In this embodiment, the sensor can convert the detected sampling signal (such as voltage, current, etc.) into an electrical signal, and the comparator can accurately compare the signal output by the sensor with the reference voltage, thereby determining whether the output voltage deviates from the expected value. This is a key step in achieving closed-loop control. The comparator has a fast response speed and can compare the signal and output the corresponding result in a short time, which helps to speed up the response speed of the closed-loop control system and improve the dynamic performance of the system. The feedback path circuit feeds the output voltage signal back to the input end and compares it with the given signal to form a closed-loop control system, which helps to eliminate system errors and improve the stability and accuracy of the output voltage. The closed-loop control system has strong anti-interference ability and can suppress the impact of external interference on the system through the feedback mechanism, which enables the closed-loop feedback signal conditioning circuit to maintain stable performance in a noisy environment. The introduction of the feedback path circuit can speed up the response speed of the system, especially when the system is subject to external interference or load changes, which helps to ensure that the system can quickly recover to a stable state.

[0072] Preferably, the magnetic field generating module adopts a flexible hollow coil.

[0073] In this embodiment, the flexible hollow coil is small in size and has good portability. It can be in close contact with the wearer's body and has the ability to bend and stretch. In order to further improve the wearing comfort and stability, the flexible hollow coil, due to its soft and flexible characteristics, makes the deployment and adjustment of the magnetic field generating module more flexible. Whether in a limited space or in a complex environment, the flexible coil can easily adapt to meet various magnetic field control needs. The flexible hollow coil can be customized in different shapes and sizes according to actual needs, such as circular, rectangular, elliptical, etc., as well as different diameters and lengths. This flexibility makes the magnetic field generating module suitable for more diverse application scenarios. The flexible hollow coil can generate a uniformly distributed magnetic field after being energized. It is crucial for application scenarios that require precise control of magnetic field strength and direction. A uniform magnetic field helps ensure the accuracy and stability of magnetic field regulation. By adjusting the current size and direction of the flexible hollow coil, the strength and direction of the generated magnetic field can be easily adjusted. This adjustment capability enables the magnetic field generating module to meet the magnetic field requirements of different application scenarios. Flexible hollow coils are usually made of high-quality insulating materials and conductors, and have good wear resistance and corrosion resistance, which enables the magnetic field generating module to maintain long-term stable performance in harsh working environments. The structure of the flexible hollow coil is simple and stable, and is not easily affected by external interference and damage. Therefore, the magnetic field generating module has high reliability and can ensure stable magnetic field output during long-term operation.

[0074] Preferably, the flexible coil is provided with a silicone coil cover on the outside.

[0075] In this embodiment, the flexible coil is equipped with a silicone coil cover. The silicone coil cover is soft and durable, effectively protecting the coil from damage while ensuring the softness of the portion in contact with the human body, thereby enhancing comfort and stability during treatment. The coil can be worn on the human body to generate a stable magnetic field and is suitable for spleen immunomodulation applications. In addition, the silicone coil cover, with its soft and wear-resistant properties, can effectively reduce damage and wear on the outer surface of the coil. In complex or harsh working environments, the silicone cover can protect the coil from external friction and scratches, thereby extending the service life of the coil. The silicone material has excellent vibration resistance and cushioning properties, which can alleviate external impact on the coil. When the coil is subjected to external impact or compression, the silicone cover can absorb some of the impact force and protect the internal structure of the coil from damage. The silicone coil cover can effectively block external moisture and dust from invading the coil interior, thereby reducing contamination and corrosion of the coil, keeping the coil clean and dry, and improving the operational stability and reliability of the coil. The silicone material has excellent high and low temperature resistance and can maintain stable performance under extreme temperature conditions. This allows the silicone coil cover to protect the coil in high or low temperature environments and ensure the normal operation of the coil.

[0082] Step f: The user continuously operates the operation buttons in the user interaction module to adjust the set value of the output voltage in real time, thereby achieving continuous or step-by-step adjustment of the magnetic field strength and frequency.

[0083] In this embodiment, in step e, the magnetic field generating module generates a corresponding magnetic field based on the voltage input sent by the control module. The user can adjust the intensity and frequency of the magnetic field by setting different voltage values. This flexibility enables the magnetic field control device to adapt to a variety of application scenarios.
