[0002] The physiotherapy comb belongs to a scalp comb and is often used for daily care and health care such as hair loss, scalp itching, and desquamation. For example, a Chinese patent with the authorization announcement number CN 202876096 U discloses an electronic vibration physiotherapy comb, which is composed of a comb main body composed of a comb tooth body and a comb back body, a vibrator, and a circuit system. When in use, by pressing the first gear of the button of the two-gear slide switch K, the power supply is connected to the circuit system through the contact K-1, and the pulse current output from the physiotherapy point at the tip of the comb teeth performs electronic physiotherapy on the cerebral cortex of the human body.

[0003] However, for the above-mentioned electronic physiotherapy combs and other traditional electric physiotherapy combs, their voltage gears are fixed, not easy to adjust, and cannot realize the output selection of multiple different voltages, which brings inconvenience to users. After analyzing the previous technical means, the utility model proposes an adjustment and control system for voltage output of a physiotherapy comb to solve the problem of unable to adjust the voltage output of different gears. Summary of the Utility Model

[0004] Aiming at the above defects, the utility model provides an adjustment and control system for voltage output of a physiotherapy comb, which is used for the voltage boosting function of the physiotherapy comb, so as to adjust the voltage output of different gears and provide convenience for users.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

The voltage detection pin of the main chip is connected to the FB pin to R19;

[0010] The system unit control module includes at least an EMS_SET pin, an AD pin, a PWM pin, a VDD_5V pin, and an FB pin. The EMS_SET pin is connected to the first boost module, and the EMS_5V terminal of the first boost module is connected to the EMS_5V terminal of the second boost module.

[0011] For the technical solution formed by the above technical means, a further technical solution can be formed, including:

[0022] The adjustment and control system for the voltage output of the physiotherapy comb implemented by the present utility model aims to solve the many inconveniences brought to users by the traditional physiotherapy comb in the past due to its inability to achieve the output selection of multiple different voltages.

[0023] As Figure 3 shown, for the adjustment and control system for the voltage output of the physiotherapy comb implemented by the present utility model, the model of the system unit control module used is AI04_001_V0. For the composition of each pin, reference can be made to Figure 3 , its pins 1-5 are POWER_SW, LEVEL, EMS_IN-, EMS_IN+, VPP in sequence, pin 7 is DATA, pin 10 is EMS_SET, and pins 12-20 are AD, EN, PWM, VDD_5V, RF_SET, CHK_BAT, VIN_CHK / SDA, SCK, FB in sequence.

[0024] As Figures 1-4 shown, for the adjustment and control system for the voltage output of the physiotherapy comb implemented by the present utility model, among them, Figure 1 the circuit diagram shown is the first boost module and is used to boost the voltage from 3.7V to 5V, Figure 2 the circuit diagram shown is the second boost module and is used to boost the voltage from 5V to 200V. The 10th pin EMS_SET of the system unit control module is connected to the Figure 1 EMS_SET of the first boost module shown. The EMS_5V connection end of the first boost module is then connected to the EMS_5V contact point of the second boost module.

[0025] In Figure 1 the first boost module shown, the BAT+ contact point is connected to the Q5 component of model AO3401. This Q5 component is connected to the L5 component of 22UH and the IC9 component in sequence. The component C18 is then connected to the Q4 component of SS8050; in Figure 2 the second boost module shown, a 2.2mH L6 is provided between the EMS_5V contact point and the D5 component. The D5 component is connected to the Q6 component. In the second boost module, there are also included the Q7 component and the C12 component.

[0026] The regulation and control system for voltage output of the physiotherapy comb implemented by the present utility model, when working, after the 3.7V power supply passes through the power inductor L5 and the boost chip IC9, the voltage rises to 5V, and then passes through the power inductor L6 and the diode D5. The main chip outputs a 20KHZ frequency to the PWM pin, through the resistor R17 and the triode Q6 to the positive pole of the diode D5, and 200V is output from the negative pole of the diode D5. The voltage detection pin of the main chip is connected to the FB connection pin to R19; in addition, for this FB pin responsible for voltage feedback, if the voltage is too high, the main chip will automatically adjust the duty cycle of the frequency of the PWM pin, so as to achieve the functions of constant voltage and stable voltage; the AD pin controls the voltage through the resistor R21, the triode Q7 and the resistor R23. When the voltage of 200V needs to instantaneously drop to 20V, the AD and PWM pins are responsible at the same time. It can be seen that for the voltage boost function, it is possible to conveniently adjust the voltage output of different gears.

Those who are familiar with the technology in this field can obviously make various modifications to these examples easily, and apply the general principles described here to other embodiments without creative labor. Therefore, the protection scope of the present utility model is not limited to the above situations.
