In some embodiments, the hair removal device or skin rejuvenation device 1 can be, but is not limited to, a beauty device, a skin beauty device, a skin rejuvenation device, a hair removal device, a care device, or other electronic devices for beauty and skin care.

[0089] The hair removal device or skin rejuvenation device 1 may include a charging circuit 100 and a light output module 70 .

[0090] The power supply circuit 100 is connected to the light output module 70, and the power supply circuit 100 can be used to power the light output module 70. The light output module 70 can be used to irradiate light according to the power supply of the power supply circuit 100, and the light output module 70 can irradiate light to human skin to take care of human skin. In some embodiments, the light output module 70 can be, but is not limited to, a xenon lamp or other luminous electronic device, which can irradiate preset light, such as energy light, through the power supply of the power supply circuit 100.

[0091] See also Figure 1 The charging circuit 100 may include a power input module 10 , an energy storage module 20 , a voltage acquisition module 30 and a control module 40 .

[0092] The power input module 10 is connected to the energy storage module 20, and the power input module 10 is used to provide charging power to the energy storage module 20. In some embodiments, the power input module 10 can be a voltage conversion device or a power adapter, etc., which outputs a preset power to the energy storage module 20 after voltage conversion by connecting to an external power supply. For example, the power input module 10 is connected to an external AC or DC power supply, and outputs 24V DC to the energy storage module 20 after voltage conversion to provide DC charging power to the energy storage module 20.

[0093] The energy storage module 20 is used to store electric energy and charge and discharge. The energy storage module 20 can obtain charging electric energy through the power input module 10, and the energy storage module 20 can also release electric energy to power the light output module 70. In some embodiments, the energy storage module 20 can be a rechargeable battery or capacitor.

[0094] The voltage acquisition module 30 is connected to the energy storage module 20 and the control module 40 respectively. The voltage acquisition module 30 can be used to collect the voltage of the energy storage module 20 and feed back the collected voltage to the control module 40. In some embodiments, when the energy storage module 20 is charged through the power input module 10, the voltage acquisition module 30 can collect the real-time voltage of the energy storage module 20 to obtain the charging status of the energy storage module 20.

[0095] The control module 40 is connected to the power input module 10 and the voltage acquisition module 30 respectively, and the control module 40 can be used to control the power input module 10 to charge the energy storage module 20 according to the acquisition voltage fed back by the voltage acquisition module 30. In some embodiments, the control module 40 is provided with a first voltage threshold and at least one second voltage threshold, and the first voltage threshold can be a safety voltage threshold set for the energy storage module 20. For example, when the current voltage of the energy storage module 20 is greater than or equal to the first voltage threshold, that is, the safety voltage threshold, the energy storage module 20 may be in an overvoltage state and easily damaged; at least one second voltage threshold is a set voltage threshold according to the charging requirements of the energy storage module 20, for example, according to the charging requirements of the energy storage module 20, such as the power level that the energy storage module 20 needs to release to the light output module 70, and multiple different second voltage thresholds are set. In some embodiments, the control module 40 can be provided with multiple different second voltage thresholds, and the current second voltage threshold is selected, for example, the second voltage threshold corresponding to the power level that the energy storage module 20 needs to release to the light output module 70 is selected.

[0096] The control module 40 can also be used to determine the collected voltage fed back by the voltage collection module 30 and the first voltage threshold and at least one second voltage threshold. When the control module 40 determines that the collected voltage fed back by the voltage collection module 30 is greater than or equal to the first voltage threshold or at least one second voltage threshold, the control module 40 can output a control signal to shut down the charging of the energy storage module 20 by the power input module 10, thereby protecting the energy storage module 20 and preventing the overcharging of the energy storage module 20 by shutting down the power input module 10, thereby improving the safety of the hair removal device or skin rejuvenation device 1.

[0097] In some embodiments, when the control module 40 is provided with a plurality of different second voltage thresholds and the current second voltage threshold is selected, the control module 40 determines the collected voltage fed back by the voltage collection module 30 and the first voltage threshold and the current second voltage threshold. When the control module 40 determines that the collected voltage fed back by the voltage collection module 30 is greater than or equal to the first voltage threshold or the current second voltage threshold, the control module 40 may output a control signal to shut down the charging of the energy storage module 20 by the power input module 10.

[0098] In some embodiments, when the current second voltage threshold selected from a plurality of different second voltage thresholds is less than the first voltage threshold, and when the control module 40 determines that the collected voltage fed back by the voltage collection module 30 is greater than or equal to the current second voltage threshold, the control module 40 may output a control signal to shut down the charging of the energy storage module 20 by the power input module 10. In other embodiments, when the current second voltage threshold selected from a plurality of different second voltage thresholds is greater than the first voltage threshold, and when the control module 40 determines that the collected voltage fed back by the voltage collection module 30 is greater than or equal to the first voltage threshold, the control module 40 may output a control signal to shut down the charging of the energy storage module 20 by the power input module 10. Thus, the charging of the energy storage module 20 by the power input module 10 will not exceed the safety voltage threshold of the energy storage module 20, thereby protecting the energy storage module 20 and preventing the overcharging of the energy storage module 20 by shutting down the power input module 10, thereby improving the safety of the hair removal device or skin rejuvenation device 1.

The second control submodule 44 is used to determine the collected voltage fed back by the voltage collection module 30 and the first voltage threshold and at least one second voltage threshold. When the second control submodule 44 determines that the collected voltage is greater than or equal to the first voltage threshold or at least one second voltage threshold, the second control submodule 44 outputs a control signal to the first control submodule 42, so that the first control submodule 42 shuts off the charging of the power input module 10 to the energy storage module 20.

Exemplarily, the second side 214 of the first energy storage capacitor C21 and the third side 222 of the second energy storage capacitor C22 are set to the positive pole +, and the first side 212 of the first energy storage capacitor C21 and the fourth side 224 of the second energy storage capacitor C22 are set to the negative pole -, then the polarity arrangement of the two energy storage capacitors C21 and C22 from one side to the other can be negative pole -, positive pole +, positive pole +, negative pole -; or, the second side 214 of the first energy storage capacitor C21 and the third side 222 of the second energy storage capacitor C22 are set to the negative pole -, and the first side 212 of the first energy storage capacitor C21 and the fourth side 224 of the second energy storage capacitor C22 are set to the positive pole +, then the polarity arrangement of the two energy storage capacitors C21 and C22 from one side to the other can be positive pole +, negative pole -, negative pole -, positive pole +.

[0165] The second side portion 214 of the first energy storage capacitor C21 is connected to the third side portion 222 of the second energy storage capacitor C22 through the first wire 242, and the first side portion 212 of the first energy storage capacitor C21 is connected to the fourth side portion 224 of the second energy storage capacitor C22 through the second wire 244. That is, the polarity of the adjacent side of the two energy storage capacitors C21 and C22 is the same, and they are connected through the first wire 242, and the polarity of the opposite side of the two energy storage capacitors C21 and C22 is the same, and they are connected through the second wire 244. Among them, the first wire 242 and the second wire 244 do not intersect. Therefore, the connecting wires of the two energy storage capacitors C21 and C22 will not form flying wires, which is more conducive to the internal layout design of the hair removal device or skin rejuvenation device 1.

[0166] Please also read Fig.10 The hair removal device or skin rejuvenation device 1 may further include a circuit board 101. A receiving hole 102 is provided through the circuit board 101, and two energy storage capacitors C21 and C22 are adjacently arranged in the receiving hole 102.

[0167] In some embodiments, the two energy storage capacitors C21 and C22 may have the same energy storage capacity, and the total energy storage capacity of the energy storage module 20 is the sum of the energy storage capacities of the two energy storage capacitors C21 and C22. In other embodiments, the two energy storage capacitors C21 and C22 may have different energy storage capacities, and the total energy storage capacity of the energy storage module 20 is the sum of the energy storage capacities of the two energy storage capacitors C21 and C22.

[0168] It can be understood that the adjacent arrangement of the two energy storage capacitors C21 and C22 can effectively reduce the volume, occupy a smaller space inside the hair removal device or skin rejuvenation device 1, and is more conducive to the layout design inside the hair removal device or skin rejuvenation device 1, compared with the traditional single large energy storage capacitor. At the same time, the sum of the energy storage capacity of the two energy storage capacitors C21 and C22 can increase the energy storage capacity of the energy storage module 20 and the charging and discharging capacity of the energy storage module 20, compared with the capacity of the traditional single large energy storage capacitor, which is conducive to adapting the hair removal device or skin rejuvenation device 1 to more functional applications.

The first energy storage capacitor C21 and the second energy storage capacitor C22 can also include a positive connection terminal C+ and a negative connection terminal C-, respectively, which can be used to connect to other unit modules for charging and discharging.

[0170] In some embodiments, each energy storage capacitor C21, C22 has a voltage threshold, such as a first voltage threshold and a second voltage threshold. When the energy storage capacitors C21, C22 are charged to the voltage threshold, the energy storage capacitors C21, C22 may stop charging to prevent overcharging.

[0171] See also Fig.12 , which is a schematic diagram of a hair removal device or skin rejuvenation device provided by an embodiment of the present application. The hair removal device or skin rejuvenation device 1 may include a power input module 10, an energy storage module 20, a light output module 70, and a detection module 96.

[0172] The power input module 10 is connected to the energy storage module 20, and the power input module 10 is used to provide charging power to the energy storage module 20. In some embodiments, the power input module 10 can be a voltage conversion device or a power adapter, etc., which outputs a preset power to the energy storage module 20 after voltage conversion by connecting to an external power supply. For example, the power input module 10 is connected to an external AC or DC power supply, and outputs 24V DC to the energy storage module 20 after voltage conversion to provide DC charging power to the energy storage module 20.

[0173] The energy storage module 20 is used to store electric energy and charge and discharge. The energy storage module 20 can obtain charging electric energy through the power input module 10. The energy storage module 20 can also release electric energy to power the light output module 70. In some embodiments, the energy storage module 20 can be a rechargeable battery or a capacitor. In some embodiments, the energy storage module 20 can be set at a preset threshold value, which is used to characterize the preset threshold value corresponding to the discharge of the energy storage module 20 to the light output module 70 so that the light output module 70 irradiates light. In some embodiments, the preset threshold value can correspond to the voltage threshold value that the energy storage module 20 needs to be charged to each time the light output module 70 irradiates light. After the energy storage module 20 is charged to the preset threshold value, the energy storage module 20 can supply power to the light output module so that the light output module 70 irradiates light.

[0174] The light emitting module 70 is connected to the energy storage module 20. The light emitting module 70 can be used to irradiate light according to the power supply of the energy storage module 20. The light emitting module 70 can irradiate light to human skin to care for human skin. In some embodiments, the light emitting module 70 can also include a trigger detection function, which can detect a user trigger operation. Exemplarily, the light emitting module 70 can also include a trigger button 72, and the trigger button 72 can detect a user trigger operation, such as pressing or touching. The user trigger operation can correspond to triggering the light emitting module 70 to irradiate light. In some embodiments, the trigger button can be but is not limited to a physical button or a touch button. The light emitting module 70 can be provided with a light outlet 74, which can be an outlet for the light irradiated by the light emitting module 70, and the light outlet 74 can be provided at one end of the body of the hair removal device or skin rejuvenation device 1.

[0175] The detection module 96 is connected to the energy storage module 20, and the detection module 96 can be used to detect whether it is fully contacted. The detection module 96 can be arranged on the end face of the light outlet 74 and arranged around the light outlet, and can be used to detect whether it is fully contacted. In some embodiments, the detection module 96 can be but is not limited to a capacitive touch sheet. When the capacitive touch sheet is contacted, for example, when it is contacted by the user's skin, the degree of contact can be detected according to different capacitance change rates, so as to determine whether it is fully contacted. Exemplarily, when the user uses and operates the hair removal device or skin rejuvenation device 1, the light outlet 74 can be placed close to the user's skin, and the detection module 96 arranged at the light outlet 74 can detect whether it is fully contacted. When the detection module 96 detects that it is fully contacted, when the light outlet 74 is completely shielded, the light emitted by the light outlet module 70 through the light outlet 74 can directly reach the user's skin without light leakage, etc., thereby improving the safety of the hair removal device or skin rejuvenation device 1.

[0176] When the light emitting module 70 is triggered, the detection module 96 detects that it is fully contacted, and the energy storage module 20 is charged to a preset threshold, the energy storage module 20 releases electric energy to the light emitting module 70 to power the light emitting module 70, and the light emitting module 70 irradiates light. Exemplarily, when the user operates the hair removal device or the skin rejuvenation device 1, the light outlet 74 is placed close to the user's skin, the detection module 96 can detect that it is fully contacted, the user operates the trigger button 72 of the light emitting module 70, the light emitting module 70 can detect that it is triggered, the energy storage module 20 detects whether the charging reaches the preset threshold, and when the charging reaches the preset threshold, the energy storage module 20 can release electric energy to the light emitting module 70 to power the light emitting module 70, and the light emitting module 70 can work according to the power supply of the energy storage module 20 to irradiate light, and the light emitting module 70 irradiates light to the user's skin to perform beauty and skin care on the skin.

[0177] The hair removal device or skin rejuvenation device 1 of the present embodiment requires multiple triggering conditions to be met in order for the light emitting module 70 to irradiate light, namely, when the light emitting module 70 is triggered, the detection module 96 detects full contact, and the energy storage module 20 is charged to a preset threshold, the hair removal device or skin rejuvenation device 1 can cause the light emitting module 70 to irradiate light; when any of the triggering conditions is not met, the hair removal device or skin rejuvenation device 1 cannot complete the triggering and irradiating light, which can effectively avoid the false triggering of some hair removal devices or skin rejuvenation devices 1, thereby improving the safety of the hair removal device or skin rejuvenation device.

[0178] Please also read Fig.13In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a voltage acquisition module 30. The voltage acquisition module 30 is connected to the energy storage module 20, and the voltage acquisition module 30 may be used to detect the voltage of the energy storage module 20. In some embodiments, when the energy storage module 20 is charged through the power input module 10, the voltage acquisition module 30 may detect the real-time voltage value of the energy storage module 20 to obtain the charging status of the energy storage module 20. In some embodiments, when the voltage acquisition module 30 detects that the voltage value of the energy storage module 20 reaches a preset threshold, the power input module 10 may stop charging the energy storage module 20. It can be understood that when the voltage acquisition module 30 detects a preset threshold value of the voltage value of the energy storage module 20, that is, it represents the voltage threshold to which the energy storage module 20 needs to be charged each time the light emitting module 70 irradiates light, after charging to the preset threshold value, the power input module 10 can stop charging the energy storage module 20, and continue to charge the energy storage module 20 after the energy storage module 20 is discharged to the light emitting module 70; or, after charging to the preset threshold value, the power input module 10 can continue to charge the energy storage module 20 until the energy storage module 20 is charged to the first voltage threshold value or the second voltage threshold value, such as the safety voltage threshold value set by the energy storage module 20, and the power input module 10 can stop charging the energy storage module 20, thereby preventing overcharging and ensuring the safety of the energy storage module 20.

[0179] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a refrigeration module 97, which may be connected to the energy storage module 20 and arranged corresponding to the light output module 70. The refrigeration module 97 may be used to reduce the temperature. In some embodiments, the refrigeration module 97 may be arranged around the light output port 74 of the light output module 70. When the light output port 74 is close to the user's skin, the refrigeration module 97 is also close to the user's skin. When the light output module 70 irradiates light to the user's skin, the energy of the light may generate a certain amount of heat. The refrigeration module 70 may refrigerate and reduce the user's skin temperature to offset the heat generated by the light energy, thereby improving the user's comfort when using the hair removal device or skin rejuvenation device 1. It can be understood that when the refrigeration module 97 is close to the user's skin, the area where the refrigeration module 97 produces a refrigeration effect corresponds to the area where the light output module 70 irradiates light through the light output port 74, so that the user's skin area undergoing beauty and skin care can be cooled or iced at the same time.

[0180] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a heat dissipation module 98, and the heat dissipation module 98 may be connected to the energy storage module 20. The heat dissipation module 98 may be used to provide heat dissipation when the hair removal device or skin rejuvenation device 1 is working. It can be understood that when the hair removal device or skin rejuvenation device 1 is working, related modules, such as the energy storage module 20 charging and discharging, the light output module 70 irradiating light, the detection module 96 working, the refrigeration module 97 cooling, etc., will generate some heat in the hair removal device or skin rejuvenation device 1 body due to the work of related modules. The heat dissipation module 98 may be used to conduct the heat in the hair removal device or skin rejuvenation device 1 body to the outside of the body, to prevent the hair removal device or skin rejuvenation device 1 from overheating, and to improve the safety of the hair removal device or skin rejuvenation device 1. In some embodiments, the heat dissipation module 98 and the light outlet 74 of the light outlet module 70 and the refrigeration module 97 can be respectively arranged at opposite ends of the body of the hair removal device or skin rejuvenation device 1, the light outlet 74 and the refrigeration module 97 can be close to the end of the user's skin, and the heat dissipation module 98 can be the end away from the user's skin, so that the emitted heat does not affect the user and improves the user experience. It can be understood that when the hair removal device or skin rejuvenation device 1 is turned on, the heat dissipation module 98 can start working at the same time and provide heat dissipation synchronously; when the hair removal device or skin rejuvenation device 1 is turned off, the heat dissipation module 98 can stop working.

[0181] In some embodiments, the heat dissipation module 98 may include at least one fan 982, which may be disposed inside the body of the hair removal device or skin rejuvenation device 1 to transfer the heat generated by the light output module 70 and the refrigeration module 97 when they are working from one end of the body of the hair removal device or skin rejuvenation device 1 to the other end, and further to the outside of the hair removal device or skin rejuvenation device 1.

[0182] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a voltage conversion module 90, which is connected between the energy storage module 20 and the light output module 70. The voltage conversion module 90 can be used to convert the electric energy released by the energy storage module 20 into a working voltage corresponding to the energy level according to a preset energy level, so that the light output module 70 irradiates light of the energy level corresponding to the working voltage.

[0183] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a control module 40, which is connected to the voltage conversion module 90. The control module 40 may be used to set the energy level and pulse width. The energy level may be used to characterize the voltage conversion module 90 converting the supply voltage output by the energy storage module 20 to the working voltage level of the light output module 70, so that the light output module 70 may irradiate light of different energy levels according to the working voltage level; the pulse width may be used to characterize the time for the light output module 70 to irradiate light.

[0184] Exemplarily, the control module 40 can set multiple energy gears and multiple pulse widths, such as the first energy gear, the second energy gear and the third energy gear, which correspond to light of different energy intensities respectively; the first pulse width, the second pulse width and the third pulse width correspond to different light exposure times respectively. The control module 40 can also set a combination of multiple energy gears and multiple pulse widths, such as the first energy gear with the second pulse width, to characterize the length of time that the light output module 70 irradiates light with the first energy intensity and irradiates the second pulse width. In some embodiments, the control module 40 can also set the current energy gear and pulse width in response to user operations (such as selection operations), and the voltage conversion module 90 can be used to convert the electrical energy released by the energy storage module 20 into an operating voltage corresponding to the energy gear according to the set energy gear, so that the light output module 70 irradiates the energy of the corresponding gear according to the operating voltage, and continuously irradiates the light for the duration corresponding to the pulse width.

[0185] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a driving module 94, which is connected to the voltage conversion module 90 and the light output module 70. The driving module 94 can be used to generate a trigger signal when the hair removal device or skin rejuvenation device 1 is triggered by light output, for example, when the light output module 70 is triggered, the detection module 96 detects that it is fully contacted, and the energy storage module 20 is charged to a preset threshold. The driving module 94 is used to turn on the connection between the voltage conversion module 90 and the light output module 70 according to the trigger signal, so that the voltage conversion module 90 can provide an operating voltage to the light output module 70, and the light output module 70 can irradiate light according to the operating voltage.

[0186] In some embodiments, the hair removal device or skin rejuvenation device 1 may further include a voltage stabilizing module 94, which is connected between the power input module 10 and the driving module 92. The power input module 10 may be used to provide a DC voltage, and the voltage stabilizing module 94 is used to convert the DC voltage provided by the power input module 10 and provide it to the driving module 92, so that the driving module 94 can obtain a working voltage.

[0187] The hair removal device or skin rejuvenation device 1 of the embodiment of the present application enables the light emitting module 70 to irradiate light, which needs to meet multiple triggering conditions, that is, when the light emitting module 70 is triggered, the detection module 96 detects that it is fully contacted, and the energy storage module 20 is charged to a preset threshold, the hair removal device or skin rejuvenation device 1 can enable the light emitting module 70 to irradiate light, which can effectively improve the safety of the hair removal device or skin rejuvenation device. In addition, according to the setting of different energy levels and pulse widths, the light emitting module 70 can irradiate light of different energy intensities and different irradiation durations, which can achieve different beauty and skin effects.
