Technical Field

[0001] This application relates to the field of beauty instruments, and in particular to a circuit and hair removal device. Background Technology

[0002] As living standards continue to improve, people's demand for hair removal is also increasing. Among the related technologies, hair removal is done using a razor, but as time goes by, new hair will grow back quickly, requiring repeated hair removal with a razor. Another related technology is to use hair removal cream. After using hair removal cream, the hair also needs to be removed repeatedly, and both of these technologies require a high frequency of hair removal. Summary of the Invention

[0003] To reduce the frequency of hair removal, this application provides a circuit and a hair removal device.

[0004] First aspect

[0005] The circuit provided in this application adopts the following technical solution:

[0006] A circuit includes a controller circuit, a drive circuit, a transformer circuit, a laser circuit, and a high-voltage triggering circuit;

[0007] The first output terminal of the controller circuit is connected to the input terminal PWM_Driver of the drive circuit, the output terminal of the drive circuit is connected to the input terminal of the transformer circuit, the output terminal H_V of the transformer circuit is connected to the first terminal of the laser circuit, the second terminal of the laser circuit is grounded, the input terminal of the high-voltage trigger circuit is connected to the output terminal H_V of the transformer circuit, and the output terminal of the high-voltage trigger circuit is connected to the trigger terminal of the laser circuit.

[0008] By adopting the above technical solution, the controller circuit outputs a PWM signal, which in turn controls the drive circuit to generate a square wave signal. The square wave signal is transmitted to the transformer, which boosts the voltage of the square wave signal, thereby outputting a high-voltage pulse signal at the output terminal of the transformer. The pulse signal is transmitted to the laser circuit, and simultaneously, the pulse signal is transmitted to the trigger terminal of the laser circuit through the high-voltage trigger circuit, thereby causing the laser circuit to generate strong pulse light. Users can then use the strong pulse light for hair removal, thereby achieving the purpose of hair removal. The strong pulse light acts on the hair follicle, reducing the possibility of hair growth. Compared with hair removal methods using shavers and hair removal creams, the frequency of hair removal is reduced.

[0009] Optionally, the input terminal of the transformer circuit is also connected to a first consumption circuit, which is used to consume the current generated by the self-induced electromotive force at the input terminal of the transformer circuit.

[0010] By adopting the above technical solution, a first consumption circuit is connected to the input terminal of the transformer circuit. The first consumption circuit can eliminate the current generated by the self-induced electromotive force in the transformer circuit, thereby reducing the possibility of damage to the transformer circuit. The first consumption circuit plays a protective role.

[0011] Optionally, a sampling circuit is also included, wherein the sampling terminal of the sampling circuit is connected to the output terminal H_V of the transformer circuit, and the output terminal HV_AD of the sampling circuit is connected to the first input terminal of the controller circuit.

[0012] By adopting the above technical solution, the sampling circuit is used to sample the high-voltage pulse signal output by the transformer. The sampling result is transmitted to the controller circuit. The data of the high-voltage pulse signal is obtained through the sampling result, thereby determining whether the high-voltage pulse signal output by the transformer meets the requirements.

[0013] Optionally, a fan control circuit is also included, wherein the switch control terminal FAN of the fan control circuit is connected to the second output terminal of the controller circuit, and the speed control terminal Speed ​​of the fan control circuit is connected to the third output terminal of the controller circuit.

[0014] By adopting the above technical solution, the controller circuit uses the switch control terminal of the fan control circuit to control whether the fan works or not. When the fan is working, the fan can play a role in heat dissipation. The controller circuit uses the speed adjustment terminal to adjust the fan speed, thereby achieving better heat dissipation.

[0015] Optionally, a cooling control circuit is also included, wherein the control terminal Cool of the cooling control circuit is connected to the fourth output terminal of the controller circuit.

[0016] By adopting the above technical solution, the controller circuit sends an electrical signal to the refrigeration control circuit, thereby controlling whether the refrigeration control circuit works. When the refrigeration control circuit works, it uses its refrigeration function to dissipate heat.

[0017] Optionally, a temperature detection circuit is also included, the output of which is connected to the second input of the controller circuit.

[0018] By employing the above technical solution, the temperature detection circuit detects the temperature and sends a real-time temperature value electrical signal to the controller circuit. The controller circuit receives the temperature value signal, converts it into a real-time temperature value, and compares it with a preset temperature value. When the real-time temperature value is greater than the preset temperature value, the controller circuit stops outputting electrical signals, thus stopping the entire circuit and providing protection. When the real-time temperature value is less than the preset temperature value, the controller circuit continues to output electrical signals to keep the circuit operational. Using a temperature detection circuit reduces the possibility of circuit damage due to high temperatures.

[0019] Optionally, a touchpad circuit is also included, wherein the output terminal TouchA of the touchpad circuit is connected to the third input terminal of the controller circuit.

[0020] By adopting the above technical solution, after contacting the user's skin, the touchpad circuit sends an electrical signal to the controller circuit. Only after the controller circuit receives this electrical signal can it control the circuit to work. Otherwise, the controller circuit will not send a control electrical signal, thereby reducing the possibility of strong pulse light damaging the user's eyes.

[0021] Optionally, an indicator light circuit is also included, wherein the connection terminal of the indicator light circuit is connected to the fifth output terminal of the controller circuit, and the indicator light circuit is used to indicate the gear and mode of the controller circuit.

[0022] By adopting the above technical solution, indicator lights are used to indicate the mode and gear of the controller circuit, making it easier for users to understand the current mode and gear of the controller circuit, and thus making it easier for users to use.

[0023] Optionally, a Bluetooth circuit is also included, wherein the data terminal of the Bluetooth circuit is connected to the fourth input terminal of the controller circuit.

[0024] By adopting the above technical solution, the controller circuit can connect with other devices via Bluetooth. The controller circuit transmits its own operating mode and other data to other devices through the Bluetooth circuit. Other devices can view this data directly and can also send commands to change the settings of the controller circuit, thereby improving convenience.

[0025] Second aspect

[0027] A hair removal device includes a power supply module and a circuit as described in the first aspect, wherein the power supply module is connected to the circuit as described in the first aspect.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Users can use intense pulsed light (IPL) for hair removal to achieve the purpose of hair removal. IPL acts on hair follicles, reducing the possibility of hair growth. Compared with hair removal methods using shavers and hair removal creams, the frequency of hair removal is reduced.

[0030] 2. By connecting the first consumption circuit to the input terminal of the transformer circuit, the current generated by the self-induced electromotive force in the transformer circuit can be eliminated, thereby reducing the possibility of damage to the transformer circuit. The first consumption circuit plays a protective role.

[0031] 3. The sampling circuit is used to sample the high-voltage pulse signal output by the transformer. The sampling result is transmitted to the controller circuit. The data of the high-voltage pulse signal is obtained through the sampling result, thereby determining whether the high-voltage pulse signal output by the transformer meets the requirements.

[0076] Reference Figure 9As an optional embodiment of this application, a circuit further includes an external power supply circuit 19. The external power supply circuit 19 includes an external interface J1, resistors R3 and R6, capacitors C12, C4, C7, and C8. Pin 1 of the external interface J1 is connected to a 12V power supply terminal, and pin 3 of the external interface J1 is grounded. One end of resistor R3 is connected to pin 1 of the external interface J1, and the other end of resistor R3 is connected to resistor R6. The other end of resistor R6 is grounded. Capacitor C12 is connected in parallel with resistor R6. One end of capacitor C4 is connected to pin 1 of the external interface J1, and the other end of capacitor C4 is grounded. Capacitor C8 is connected in parallel with capacitor C7.

[0077] Pin 3 of controller U1 is connected to the junction of resistors R3 and R6, i.e., pin 3 of controller U1 is connected to the 12V_IN terminal. Pin 6 of controller U1 is connected to the 5V output terminal of the second step-down circuit through resistor R26. After the external interface J1 is powered on, it supplies power to the entire circuit.

[0078] The implementation principle of a circuit in this application embodiment is as follows: the controller U1 outputs a PWM signal, thereby controlling the driver U2 to drive the MOS transistor Q5, thereby generating a square wave signal. The transformer T1 boosts the square wave signal and outputs a high-voltage pulse signal to the IPL lamp. At the same time, the high-voltage pulse signal is boosted again by the high-voltage transformer HVL to trigger the IPL lamp to work, thereby generating strong pulse light.

[0079] The first power consumption circuit 6 and the second power consumption circuit 7 are used to eliminate high voltage signals in the circuit, thereby reducing the possibility of circuit damage.

[0080] Controller U1 controls the operation of fan 81 and cooling chip 91, both of which dissipate heat from the circuit, reducing the possibility of damage caused by high component temperatures. Furthermore, the first temperature detection circuit 121 and the second temperature detection circuit 122 detect real-time temperature values. When the real-time temperature value exceeds a preset temperature value, controller U1 stops outputting signals, thus stopping the entire circuit. When the real-time temperature value drops below the preset temperature value, controller U1 resumes outputting signals, enabling the circuit to operate. This temperature detection method reduces the possibility of circuit damage due to high temperatures.

[0081] After the touchpad 14 comes into contact with the user's skin, the touchpad 14 sends an electrical signal to the controller U1 using the touch chip U4. Only after the controller U1 receives this electrical signal can it send a control electrical signal, thereby causing the IPL lamp to emit strong pulse light. When the controller U1 does not receive this electrical signal, the controller U1 cannot send a control electrical signal, that is, the IPL lamp cannot emit strong pulse light, thereby reducing the possibility of strong pulse light damaging the user's eyes.

[0082] The indicator light circuit 15 is used to indicate the mode and level of the controller U1. When the controller U1 controls the strong pulse light emitted by the IPL light to be at level 1 to 5, the corresponding LED1 to LED5 will light up; LED6 will light up to indicate that the cooling function is on; LED7 will light up to indicate that the controller U1 is in continuous firing mode, at which time the IPL light can continuously emit strong pulse light; LED8 to LED10 will light up to indicate that the touchpad 14 is in contact with the user's skin, at which time the controller U1 can control the IPL light to work.

[0083] The Bluetooth connector U7 in the Bluetooth circuit 16 can be used to connect with other devices via Bluetooth, thereby sending the setting parameters to other devices. Users can view the settings through other devices and send commands to the controller U1 through other devices to modify the mode and gear of the controller U1.

[0084] This application also discloses a hair removal device. The hair removal device includes all the circuits described in the above embodiments, and further includes a power supply module, which includes the external power supply circuit 19, the built-in power supply, and the charging and discharging circuit in the above circuits.

[0085] The built-in power supply is connected to the charging and discharging circuit, which is connected to the 12V power supply terminal. When using the hair removal device, the built-in power supply is used for power supply, and there is no need to use the external interface J1 in the external power supply circuit 19 to connect to the external power supply, which is convenient for use. When the built-in power supply is depleted, the external interface J1 can be used to connect to the external power supply to charge the built-in power supply through the charging and discharging circuit. At the same time, it can also supply power to the entire circuit inside the hair removal device.
