The second control signal is output by the control module 2 to control the driving module 3 to output the second driving signal to drive the energy storage module 4 to release the stored energy.

Possibly, the two control signals in the embodiment of the present application may be generated by a Micro Controller Unit (MCU) predefined setting.

Further, the optical coupling and isolation module 7 in the embodiment of the present application may further include a first level shift unit 42 and a second level shift unit 44. The first level conversion unit 42 is connected to the first optical coupling and isolation unit 41, and the second level conversion unit 44 is connected to the second optical coupling and isolation unit 43.

The second level conversion unit 44 is configured to convert a logic level of the second control signal output by the second optical coupler and isolator unit 43 into a logic level matched with the driving module 3.

It can be understood that, since the high level 2.4V output by the general MCU is not yet the low level 3.5V when the driving module 3 works, it needs to be adjusted by the level conversion module.

Referring to fig. 4a, fig. 4a shows a first light coupling and isolation unit 41 and a first level shift unit 42. Wherein, the first light coupling and isolating unit 41 may include: the resistor R10, the resistor R11, and the optical coupler U1, the first level conversion unit 42 may include: resistor R12 and capacitor C7.

It can be understood that the starting voltage of the optical coupling isolation module 7 is generally 15V, but the voltage of the battery module 1 in the device is generally only about 3V, so that the voltage output by the battery module 1 (for example, a lithium battery) needs to be increased to 15V.

Therefore, in view of VCC (starting voltage of the optical coupling isolation module 7), the optical coupling isolation module 7 may control the optical coupler U1 to output a higher-voltage PWM pulse signal P _ Q1 for high-side input of the driving module 3 by the PWM pulse signal P _ Q1_ con; the optocoupler U2 is controlled by the PWM pulse signal P _ Q2_ con to output a PWM pulse signal P _ Q2 with a higher voltage for the low-side input of the driving module 3.

Possibly, the battery module 1 in the embodiment of the present application may employ a lithium battery module. Further, the first chip is used for increasing the voltage of about 3V output by the lithium battery to about 15V output so as to supply power to the optical coupling isolation module 7 to enable the optical coupling isolation module to work. The MT3608 is a DC/DC boost chip, the input voltage is 2V-24V, the output voltage is adjustable, and is not lower than the input voltage and not higher than 24V.

It can be understood that in the embodiment of the present application, two-stage boosting is realized by providing the first boosting module and the second boosting module. The first-stage boosting refers to boosting the battery voltage to VCC through the battery module; the second-stage boosting refers to boosting VCC to HV through a Boost circuit so that the energy storage module can release high voltage.

It can be understood that, in the embodiment of the present application, a bridge driving circuit formed by two NMOS transistors may be used to drive switches of two NMOS transistors to charge and discharge an energy storage capacitor, so that a coil generates a pulse magnetic field. Specifically, when P _ Q1 is at a high level, the second chip is bootstrapped to drive HO of the second chip to be at a high level, so as to turn on the NMOS transistor Q3, at this time, the NMOS transistor Q4 is in a turned-off state, at this time, R21, D6, Q3, and C15 form a loop to charge the C15, and after the charging is completed, the voltage across C15 is equal to the voltage of HV. Then, P _ Q1 is controlled to be at a low level, Q3 is turned off, P _ Q2 is at an on level at the moment, LO of the second chip is driven to be at a high level, NMOS tube Q4 is turned on, C15 is equivalent to a power supply and forms a loop with inductors L3 and Q4, and C15 discharges, so that inductor L3 generates a magnetic field, and when the magnetic field strength reaches a preset value (for example, about 500GS, which can be measured by a pulsed magnetic field tester), a pulsed magnetic field can be generated to perform magnetic therapy and magnetic heating so as to perform magnetic therapy and thermal therapy on a human body.

It should be noted that, when two NMOS transistors are driven, they cannot enter into a dead zone (i.e. the control signals of the two NMOS transistors are not completely opposite, but after the signal of one NMOS transistor is turned off, the other NMOS transistor is turned on after a delay), so as to avoid MOS burning.
