[0002] A magnetic field refers to the field that transmits the magnetic force between objects. It is composed of tiny moving particles. Under existing conditions, it cannot be seen or touched. Therefore, two magnets can act on each other without physical contact. Since the magnetism of a magnet comes from an electric current, and an electric current is the movement of electric charges, generally speaking, a magnetic field is the manifestation of the change in the force exerted on a charge at an observation point due to the intensity and velocity of the electric field of a charge moving relative to the observation point.

[0003] Nowadays, people use magnetic fields to affect the human body and promote human recovery, which is magnetic field therapy. It is to let the magnetic field act on a certain part of the human body, so that the magnetic force lines penetrate deep into the human tissue. By stimulating the human body with the magnetic field, the effect of magnetic therapy is achieved. However, the existing magnetic therapy devices have an insignificant effect on the human body, resulting in poor recovery effects on the human body. Content of the Utility Model

The control circuit board is placed in the placement grooves on the opposite sides of the two installation seats. A plurality of wiring pins are arranged on the control circuit board. Two of the wiring pins are connected to the power supply, and two of the wiring pins are connected to the communication port.

[0008] In one example, two insertion rods are fixedly connected to the lower surface of the upper shell. The two insertion rods are opposite to the side wall of the lower shell. A slot opposite to the two insertion rods is arranged on the side wall of the lower shell. A clamping component is arranged in the slot.

[0009] In one example, a square groove is provided on one side of the insertion rod, and a rotating plate is rotatably connected in the square groove. A torsion spring is provided at the connection between the rotating plate and the insertion rod. Installation grooves are provided on both sides of the lower shell body, and the installation grooves are communicated with the slots.

The two fixed seats 32 are fixedly connected to the lower shell 2. The cylindrical magnet 4 is clamped between the two fixed seats 32. During use, the internal control component 5 controls the power supply to output pulsed current to the coil 6 to drive the cylindrical magnet 4, so as to realize the continuous exchange of N and S poles to form a dynamic magnetic field. The changes include the direction and strength of the magnetic field, which can be applied to magnetic therapy, improve the improvement effect on human blood circulation, and at the same time can improve the physiological function of the human body, relieve pain, improve immunity, and promote human recovery. The structure is simple and novel.

[0024] As Figure 1 and Figure 2As shown, two mounting seats 7 are fixedly connected inside the lower housing 2. A placement groove is provided on one side of the mounting seat 7 opposite to each other. The control circuit board 51 is placed in the placement grooves opposite to each other of the two mounting seats 7. A plurality of wiring pins are provided on the control circuit board 51. Among them, two wiring pins are connected to the power supply, and two wiring pins are connected to the communication port. Among them, a high-frequency filtering capacitor, a low-frequency filtering capacitor, an SPWM upper half-bridge drive current-limiting resistor, an SPWM lower half-bridge drive current-limiting resistor, a sine wave output terminal, a chip MCU high-speed microprocessor, and a full-bridge drive chip are installed on the control circuit board 51 to provide a pulsed current for the coil 6 to drive the columnar magnet 4. A communication port is also installed on the control circuit board 51, which is mainly responsible for calibrating and stabilizing the system always after the control circuit board 51 is powered on, and initializing the control pins after reset. When in use, the control circuit board 51 is powered on, the system is calibrated and stabilized, the control pins are initialized after reset, started by the chip processor, generates an SPWM waveform, is push-pull output by two IO ports to generate a sine wave signal, and then is waveform-driven and amplified by the full-bridge drive chip for output to increase the magnetic field strength and improve the rehabilitation effect of the magnetic field on the human body.

[0025] As Figure 3 with Figure 4As shown, the lower surface of the upper shell 1 is fixedly connected with two plug rods 8, and the two plug rods 8 are opposite to the side walls of the lower shell 2. The side walls of the lower shell 2 are provided with slots opposite to the two plug rods 8, and a clamping assembly 9 is provided in the slot. A square slot is provided on one side of the plug rod 8, and a rotating plate 10 is rotatably connected in the square slot. A torsion spring is provided at the connection between the rotating plate 10 and the plug rod 8. Mounting slots are provided on both sides of the lower shell 2, and the mounting slots are communicated with the slots. The clamping assembly 9 includes a transverse plate 91, which is located in the mounting slot. The transverse plate 91 is slidably connected to the lower shell 2, and a square through slot is provided on the transverse plate 91. The plug rod 8 passes through the square through slot, and one side of the transverse plate 91 is fixedly connected to a push block 92, and the push block 92 is provided with two circular through holes, and a round rod 93 is slidably connected in the circular through hole. The round rod 93 is fixedly connected to the side wall of the mounting slot, and a first spring 94 is fixedly connected between the push block 92 and the side wall of the mounting slot, and one side of the square slot is fixedly connected to the stopper 11. The upper shell 1 is fixed to the lower shell 2 through the plug rod 8 and the transverse plate 91. When the upper shell 1 is removed, the pushing blocks 92 on both sides are pushed to slide the cross plate 91 so that the rod 8 is completely in the square slot. At this time, the rotating plate 10 is not blocked and the upper shell 1 is directly pulled to pull the rod 8 out of the slot. When the upper shell 1 is separated from the lower shell 2, there is no need to use a paddle to pry the gap between the upper shell 1 and the lower shell 2, which is beneficial to protect the upper shell 1 and the lower shell 2 and avoid deformation due to prying.

[0026] like Figure 4 As shown, a sliding plate 12 is slidably connected in the slot, and a second spring 13 is fixedly connected between the sliding plate 12 and the bottom of the slot. When the insertion rod 8 descends and passes through the square through slot, the rotating plate 10 is stuck on the lower surface of the horizontal plate 91, pushing the sliding plate 12 down and squeezing the second spring 13. When the horizontal plate 91 moves, the rotating plate 10 is out of contact with the horizontal plate 91, and the second spring 13 pushes the sliding plate 12 upward, pushing the insertion rod 8 upward, thereby increasing the gap between the lower shell 2 and the upper shell 1, making it easier to separate the lower shell 2 from the upper shell 1 and saving more effort.

[0027] Working principle: Power on through the control circuit board 51 to calibrate and stabilize the system. After reset, initialize the control pins, start with the chip processor to generate SPWM waveforms, perform push-pull output through two IO ports to generate sine wave signals, then drive and amplify the waveforms through the full-bridge drive chip and output pulsed current to the coil 6 to drive the cylindrical magnet 4, thereby generating a dynamic magnetic field with continuously alternating N and S poles. When internal maintenance is required, push the push blocks 92 on both sides to slide the cross plate 91, so that the insertion rod 8 is completely within the square through groove. At this time, the rotating plate 10 is unobstructed, and the second spring 13 pushes the sliding plate 12 upward to push the insertion rod 8 upward, increasing the gap between the lower housing 2 and the upper housing 1, and directly pull the upper housing 1 to separate the upper housing 1 from the lower housing 2.
