All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 and fig. 2, the present invention provides a control circuit of a depilating apparatus, which includes a power conversion module 100, a control module 200, an energy storage module 300, a trigger module 400, and a light source 500, which are connected in sequence.

The hair removal device is one of small electronic devices and is not suitable for a household 220V alternating current power supply. When the depilating apparatus needs to be powered on, firstly, 220V household power supply voltage is converted into a first voltage with a size of 12V and a second voltage with a size of 400V through the power conversion module 100, wherein the power conversion module 100 is electrically connected with the control module 200 and the energy storage module 300, the first voltage is used for supplying power to the control module 200, and the second voltage is used for supplying power to the energy storage module 300. It is understood that the magnitude of the second voltage varies with the variation of the energy storage module 300.
The control module 200 includes an MCU (micro controller Unit) chip and related peripheral circuits, the MCU chip is internally integrated with I/O, A/D, a timer, a counter and other functions and peripherals, and the MCU chip may be of different types as required, such as a 51-series single chip microcomputer, a PIC-series single chip microcomputer, etc. In this embodiment, an MCU chip of ST (intentionally chosen semiconductor) is used, which has higher control accuracy. The I/O interface of the MCU chip is electrically connected to the power conversion module 100 for outputting a first signal to the power conversion module 100, and the power conversion module 100 outputs a second voltage to the energy storage module 300 for charging according to the first signal, where the second voltage is greater than or equal to a voltage threshold required by the light emitted from the light source 500, in this embodiment, the second voltage is 400V, and in other embodiments, the magnitude of the second voltage may also be set according to the light source 500.
The control module 200 is electrically connected with the energy storage module 300 through the a/D interface, in order to ensure normal operation of circuit components, the voltage range of the energy storage module 300 needs to be limited between 220V and 600V, the control module 200 is provided with preset voltage values, different preset voltage values can adjust the depilating instrument to be in different gears, and therefore the light source 500 is controlled to emit pulsed light with different intensities so as to realize different beauty effects, such as whitening effect, acne effect, flaw effect, depilating effect and the like. When the energy storage module 300 reaches the preset voltage, the control module 200 outputs a second signal to the power conversion module 100 through the I/O interface, and the power conversion module 100 stops inputting the second voltage to the energy storage module 300 according to the second signal, so that the energy storage module 300 stops charging.

In one embodiment, referring to fig. 1 and fig. 2, the control module 200 includes a detection unit 210 integrated inside the MCU chip, and the detection unit 210 is electrically connected to the energy storage module 300 through the a/D interface for detecting the voltage of the energy storage module 300. When a user needs to set the depilating apparatus at different gears to achieve different cosmetic effects, the pulse intensity required by the light source 500 is different, the control module 200 may preset a reference voltage through internal software according to the pulse intensity required by the light source 500, and the control module 200 compares the detected voltage of the energy storage module 300 with the voltage set by the internal software and then outputs a first signal or a second signal. Specifically, a comparison circuit is further arranged inside the MCU chip, the comparison circuit compares the detected voltage signal with the internal software set voltage, when the voltage value represented by the voltage signal is lower than the internal software set voltage, the MCU chip outputs a first signal to the power conversion module 100 through the I/O interface, the power conversion module 100 outputs a second voltage to charge the energy storage module 300, and the voltage of the energy storage module 300 rises; when the voltage value represented by the voltage signal is higher than the internal software set voltage, the MCU chip outputs a second signal to the power conversion module through the I/O interface, the power conversion module stops outputting the second voltage to the energy storage module 300, so that the voltage of the energy storage module 300 drops, and when the voltage of the energy storage module 300 drops to a value lower than the internal software set voltage, the control module 200 outputs the first signal again, and such a process is repeated periodically, and the power conversion module 100 charges the energy storage module 300 periodically. Through adopting the control module 200 that is integrated with the detecting element 210 to can implement the voltage size that detects out energy storage module 300 through AD interface connection with control module 200 and energy storage module 300, when adopting the higher MCU chip of precision, the precision that inside software set up voltage is also higher, thereby has promoted control circuit's control accuracy, makes the voltage of energy storage module 300 remain throughout in safe voltage range.
In an embodiment, referring to fig. 2 and fig. 3, the control circuit of the hair removal device further includes a light-emitting control module 600, the light-emitting control module 600 includes a sensing unit 610 and a light-emitting button 620, the sensing unit 610 and the light-emitting button 620 are electrically connected to the control module 200, the sensing unit 610 is used for detecting whether the hair removal device contacts the skin and providing a contact signal, when the hair removal device contacts the skin, the sensing unit 610 outputs the contact signal to the control module 200, and when the light-emitting button 620 is pressed, the control module 200 outputs a trigger signal to activate the light source 500 to emit light. The sensing unit 610 includes a touch chip for sensing a contact state between the depilating apparatus and the skin and transmitting a contact signal to the control module 200, and the embodiment employs a dual-channel touch chip, which has the characteristics of high sensitivity and interference resistance, and improves the safety of the control circuit of the depilating apparatus. Fig. 3 is a schematic circuit structure diagram of the sensing unit 610, which includes a capacitor C1, a capacitor C2, and a touch chip, wherein the capacitor C1 and the capacitor C2 are used to improve the sensitivity of the sensing unit 610, the touch chip is electrically connected to a 3.3V voltage source through a VDD interface, and the VSS interface is grounded. One terminal of the capacitor C1 is grounded and the other terminal T1 is used for making contact with the skin, and similarly, one terminal of the capacitor C2 is grounded and the other terminal T2 is used for making contact with the skin. In addition, the touch chip is electrically connected to the I/O interface of the control module 200 through the PA0 interface and the PA2 interface, when T1 and T2 simultaneously sense that the epilator touches the skin, the values of the induced capacitances between T1 and T2 and the skin change, the internal software of the touch chip determines whether the epilator touches the skin according to the change of the values of the induced capacitances, and outputs a contact signal to the control module 200 through the PA0 interface and the PA2 interface.
As shown in fig. 4 and 5, when the control module 200 receives the touch signal, the light-emitting button 620 is pressed, and the control module 200 outputs a trigger signal to the trigger module 400. The light-emitting button 620 controls the light source 500 to emit light in two modes, wherein when the light-emitting button 620 is pressed for a short time, the light source 500 is in a single flashing mode, and when the light-emitting button 620 is pressed for a long time, the light source 500 is in a continuous flashing mode. The light emitting button 620 is arranged to control the light source 500 to be freely switched between the single flashing mode and the continuous flashing mode, so that different requirements of users can be met.
It can be understood that, as shown in fig. 3 and 4, when at least one end of T1 and T2 does not contact the skin, the software inside the touch chip determines that the epilating apparatus does not contact the skin sufficiently according to the change of the capacitance value, and no matter whether the light-emitting button 620 is pressed, the light source 500 does not emit light. Alternatively, when the light-out button 620 is not pressed, the light source 500 does not emit light regardless of whether the depilating apparatus contacts the skin. In addition, when the depilating apparatus is left in a state of not contacting with the skin or operating the light-emitting button 620 for a long time, the control circuit will turn off the power and not emit light.

The second light source 520 adopts a red light LED, and the red light LED is used for emitting high-purity red light and has the effects of removing wrinkles, tendering skin, whitening and fading spots. In particular, the control module 200 receives the contact signal when the epilating apparatus is in sufficient contact with the skin. At this time, when the user mainly aims at hair removal, the control module 200 outputs a trigger signal to the trigger module 400 by pressing the first light-emitting button 621, so as to control the IPL lamp tube to emit intense pulsed light to remove hair. When the user mainly aims at skin care, the second light-emitting button 622 is pressed to enable the red light LED to emit light, and when the skin care is finished, the second light-emitting button 622 is pressed again to turn off the red light LED.
