[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0053] In the beauty equipment on the market, human skin is usually massaged by distinguishing different voltage levels. However, due to the different skin characteristics of human bodies, the corresponding skin impedance values ​​are different, resulting in different currents generated by the skin under the same voltage level. Different human bodies are also sensitive to electric currents. When the current is too large or too stimulating, it will bring a bad user experience to the target. For this reason, the present application has adopted a beauty device that can adjust the voltage and current according to the skin characteristics of the target, and can perform massage beauty according to the different skin characteristics of different people, reduce the discomfort of the target, and is suitable for people with more skin types.

[0054] In an exemplary embodiment, Figure 1 As shown, a beauty device is provided, the beauty device includes a skin detection circuit 102, a controller 104 and a voltage regulating circuit 106, and the skin detection circuit 102 and the voltage regulating circuit 106 are both connected to the controller 104. The skin detection circuit 102 is used to detect skin information of an action object and transmit the skin information to the controller 104. The controller 104 sends an adjustment signal to the voltage regulating circuit 106 based on the skin information, and the voltage regulating circuit 106 outputs a corresponding action voltage based on the adjustment signal.

[0055] Specifically, the skin detection circuit 102 contacts the skin of the subject, and can obtain the skin information of the subject, such as the impedance of the skin of the subject, through the circuit structure set therein. The skin detection circuit 102 can be a circuit that passes a tiny current (the tiny current is smaller than the current generated by the beauty device during beauty massage) through the skin of the subject, and detects the value of the circuit parameter at the same time, and determines the skin information of the subject according to the value of the circuit parameter; or it can be a circuit that provides a device that can scan or detect the skin surface of the subject in the skin detection circuit 102, and obtains the output of the device as the output of the skin detection circuit 102, so as to obtain the skin information of the subject.

[0056] The controller 104 is connected to the skin detection circuit 102, and can obtain skin information, and output an adjustment signal to the voltage regulating circuit 106 according to the skin information analysis. The voltage regulating circuit 106 can convert the adjustment signal into an action voltage. The voltage regulating circuit 106 can directly contact the skin of the action object, and directly output the action voltage to the action object to perform beauty massage on the action object. When the skin information obtained is different, the controller 104 can output different adjustment signals to ensure the correspondence between the adjustment signal and the skin information. Furthermore, according to the gear selected by the action object for the beauty device, when the skin information is the same, the controller 104 can also output different adjustment signals according to different gears. The voltage regulating circuit 106 outputs different action voltages to the skin of the action object based on the adjustment signal, and performs beauty massage on the action object.

[0057] Exemplarily, the beauty device may be a beauty instrument, which has different gears, divided into high-end and low-end. The controller 104 can obtain the gear of the beauty instrument. When the skin information of the subject is the same, when the gear of the beauty instrument is high-end, the action voltage corresponding to the adjustment signal output by the controller 104 is higher, and the beauty effect on the subject is stronger; when the gear of the beauty instrument is low-end, the action voltage corresponding to the adjustment signal output by the controller 104 is lower, and the beauty effect on the subject is milder. When the gear of the beauty device is fixed at high-end or low-end, the action voltage corresponding to the adjustment signal output by the controller 104 is different according to the different skin information of the subject, so as to achieve different degrees of massage beauty according to the different skin information of the subject.

[0058] In this embodiment, the beauty device includes a skin detection circuit 102, a controller 104 and a voltage regulating circuit 106, and the skin detection circuit 102 and the voltage regulating circuit 106 are both connected to the controller 104. The skin detection circuit 102 is used to detect the skin information of the subject, and transmit the skin information to the controller 104. The controller 104 sends an adjustment signal to the voltage regulating circuit 106 based on the skin information, and the voltage regulating circuit 106 outputs a corresponding action voltage based on the adjustment signal. By taking into account the different skin qualities of the subject, the skin information of the subject is detected and different voltages and currents are output for massage, which ensures the use experience, reduces the stimulation of the beauty device to the skin, and improves the applicability.

[0059] In one embodiment, if Figure 2 As shown, the skin detection circuit 102 includes a first electrode, a second electrode and an auxiliary detection circuit 202, the first electrode is connected to the power supply voltage of the beauty device, and the second electrode is connected to the auxiliary detection circuit 202 and the controller 104. The first electrode and the second electrode are used to contact the skin of the object, and determine the skin information of the object in combination with the auxiliary detection circuit 202, and transmit it to the controller 104.

[0060] Specifically, the structure of the skin detection circuit 102 contacting the skin of the subject is a skin contact port, and the skin contact includes two electrodes, namely a first electrode and a second electrode, wherein the first electrode can be a self-electrode and the second electrode can be a negative electrode. Then in the skin detection circuit 102, by contacting the positive electrode and the negative electrode to the skin of the subject and connecting the two electrodes, the circuit between the power supply voltage of the beauty device and the auxiliary detection circuit 202 can be connected. The auxiliary detection circuit 202 can divide the circuit voltage, and the resistance value in its circuit structure is fixed. Then it can be roughly considered that the resistance in the skin detection circuit 102 is composed of the skin of the subject and the auxiliary detection circuit 202. Since the resistance value of the auxiliary detection circuit 202 is fixed, the circuit parameters transmitted by the skin detection circuit 102 to the controller 104 can characterize the impedance of the skin of the subject, that is, the skin information of the subject.

[0061] Optionally, by detecting whether the positive electrode and the negative electrode are conductive, it can be used to detect whether the beauty device is in contact with the skin. When there is no conduction between the positive electrode and the negative electrode, that is, when the skin detection port is not in contact with the skin, the skin detection circuit 102 is open circuit, and the controller 104 cannot receive the circuit parameters output by the skin detection circuit 102, that is, there is no skin information; when there is conduction between the positive electrode and the negative electrode, that is, when the skin detection port is in contact with the skin, the skin detection circuit 102 forms a path with the skin, and the controller 104 can receive the circuit parameters from the skin detection circuit 102, that is, the skin information.

[0062] Further, in one embodiment, if Figure 3 As shown, the auxiliary detection circuit 202 includes an auxiliary resistor Rf and an auxiliary capacitor Cf connected in parallel, wherein the first end of the auxiliary resistor Rf and the auxiliary capacitor Cf connected in parallel is connected to the second electrode and the controller 104, and the second end of the auxiliary resistor Rf and the auxiliary capacitor Cf connected in parallel is grounded.

[0063] Specifically, the second electrode can be the negative electrode of the skin contact port, and the positive electrode is connected to the power supply voltage Vcc of the beauty device, and the power supply voltage Vcc supplies power to the skin detection circuit 102. When the positive electrode and the negative electrode are turned on, the power supply voltage Vcc can supply power to the auxiliary detection circuit 202, and the auxiliary detection circuit 202 conditions the skin information output by the skin detection circuit 102 and outputs it to the AD port of the controller 104. The auxiliary capacitor Cf can be a filter capacitor C1, and the auxiliary resistor Rf can be a voltage divider resistor. For example, since the resistance of the skin is relatively large, it can usually reach the megohm level, and the design of the auxiliary detection circuit 202 also needs to be adjusted accordingly. The resistance value of the auxiliary resistor Rf can be set to a resistance value close to the skin resistance, such as 680 kilo-ohms; the capacitance value of the auxiliary capacitor Cf can be 0.1uF.

[0064] In this embodiment, by contacting the positive electrode and the negative electrode in the skin contact port with the skin, it is equivalent to connecting the impedance of the skin in series into the circuit through the two electrodes, so that the circuit parameter of the skin detection circuit 102 received by the controller 104, that is, the AD value, can be used as the skin information of the object. The controller 104 analyzes the skin quality of the object according to the skin information and controls the voltage regulating circuit 106 accordingly, completes the precise beauty massage for different skins, achieves the effect of accurate beauty massage for different objects, and improves the applicability.

[0065] In one embodiment, the beauty device further includes a massage component, which is connected to the skin detection circuit 102 and the voltage regulation circuit 106. The skin detection circuit 102 and the voltage regulation circuit 106 are both in contact with the skin of the subject through the massage component.

[0066] Specifically, in order to ensure the comfort of the subject, a massage component can be set in the area that contacts the skin of the subject. The structure and material composition of the massage component are not limited, and it can be made of metal material, a combination of metal and silicone material, or other materials. The massage component connects the two electrodes of the skin contact port and the voltage regulating circuit 106, so that the two electrodes and the voltage regulating circuit 106 contact the skin of the subject through the massage component. Furthermore, the massage component can also include a heating structure that can heat the massage component to a comfortable temperature (for example, 25 degrees Celsius), so that when using the beauty device for beauty treatment, the cold and hot stimulation of the beauty device on the subject can be reduced, thereby improving the comfort of the subject when using the beauty device.

[0067] Exemplarily, the massage component includes a plurality of metal electrodes and a silicone mesh, and the silicone mesh is hollowed out according to the design requirements of the beauty device to form a mesh, and a metal electrode of matching shape is placed in each hollowed-out mesh, and each metal electrode is respectively connected to the skin detection circuit 102 or the voltage regulating circuit 106. For example, in the metal electrodes of a certain column of meshes, the metal electrode in the first mesh can be a first electrode connected to the skin detection circuit 102, and the metal electrode in the second mesh can be a second electrode connected to the skin detection circuit 102. When these two metal electrodes contact the skin, the skin information of the subject can be detected and the skin information can be obtained; the metal electrode in the third mesh and the metal electrode in the fourth mesh can be connected to the voltage regulating circuit 106, receive the action voltage output by the voltage regulating circuit 106, and perform beauty treatment on the skin of the subject.

[0068] In this embodiment, a massage component is used to contact the skin of the target. Since the massage component can be made of a material and structure that feels softer to the touch, the target's comfort level is improved when the target uses the beauty device for beauty treatment, and the applicability of the beauty device is increased.

[0069] In one embodiment, if Figure 4 As shown, the voltage regulating circuit 106 includes a power conversion chip 402 and a voltage dividing circuit 404. The power conversion chip 402 is connected to the power supply voltage of the beauty device and the voltage dividing circuit 404. The voltage dividing circuit 404 is connected to the controller 104. The power conversion chip 402 is used to generate a regulated voltage based on the power supply voltage of the beauty device and transmit it to the voltage dividing circuit 404. The voltage dividing circuit 404 determines the operating voltage based on the adjustment signal and the regulated voltage.

[0070] Specifically, the power conversion chip 402 receives the power supply voltage of the beauty device, converts the voltage, and outputs a regulated voltage to the voltage divider circuit 404. At the same time, the controller 104 also outputs an adjustment signal to the voltage divider circuit 404 according to the skin information. The voltage divider circuit 404 can determine the operating voltage based on the received regulated voltage and the adjustment signal. Further, the voltage divider circuit 404 can output the operating voltage to the massage component.

[0071] It should be noted that the power supply voltage of the beauty device in this embodiment can be the same power supply voltage as the power supply voltage of the beauty device in other embodiments, or it can be a different power supply voltage. The beauty device can include multiple power supply voltages, and the voltages of the power supply voltages can be the same or different. For example, the power supply voltage connected to the power conversion chip 402 and the power supply voltage connected to the positive electrode in the above embodiment can be power supply voltages with different voltage values, or they can be power supply voltages with the same voltage value. The specific value can be selected according to the differences such as different designed circuit structures and different specifications of the beauty device, and it is not limited here. In subsequent embodiments, unless otherwise specified, it is not limited.

[0072] Optionally, the power conversion chip 402 may be a converter with multiple pins, such as a DC / DC converter. Converters with different power topologies may implement conversions such as boost, buck, and voltage regulation, and specific models may be selected based on actual usage scenarios and design requirements. For example, the model may be selected based on the voltage and power requirements of the connected power supply voltage.

[0073] Further, in one embodiment, if Figure 5 As shown, the voltage divider circuit 404 includes a first voltage divider resistor R1, a second voltage divider resistor R2, a third voltage divider resistor R3 and a fourth voltage divider resistor R4, the first end of the first voltage divider resistor R1 is connected to the power conversion chip 402, the second end of the second voltage divider resistor R2 and the first end of the fourth voltage divider resistor R4, the second end of the first voltage divider resistor R1 is grounded, the second end of the fourth voltage divider resistor R4 is connected to the first end of the third voltage divider resistor R3 and grounded, the second end of the third voltage divider resistor R3 is connected to the controller 104, and the first end of the second voltage divider resistor R2 is used to output the action voltage.

[0074] Among them, the first voltage-dividing resistor R1, the second voltage-dividing resistor R2, the third voltage-dividing resistor R3 and the fourth voltage-dividing resistor R4 are all used to divide the voltage output by the power conversion chip 402. The second end of the third voltage-dividing resistor R3 is connected to the PWM port (output I / O port) of the controller 104, and the PWM port can output a regulation signal, that is, a Vpwm signal. The PWM voltage waveform corresponding to the frequency and duty cycle is output to the second end of the third voltage-dividing resistor R3 of the voltage-dividing circuit 404 according to the skin information.

[0075] In the voltage divider circuit 404, the regulated voltage output by the power conversion chip 402 is transmitted to the first end of the first voltage divider resistor R1, the second end of the second voltage divider resistor R2, and the first end of the fourth voltage divider resistor R4, and the adjustment signal output by the controller 104 is transmitted to the second end of the third voltage divider resistor R3. Due to the voltage dividing effect of each voltage divider resistor, the voltage divider circuit 404 can determine the action voltage output by the first end of the second voltage divider resistor R2 according to the regulated voltage and the adjustment signal.

[0076] Furthermore, in one embodiment, a topology branch 602 is provided in conjunction with the power conversion chip 402, such as Figure 6 As shown, the voltage regulating circuit 106 further includes a topological branch 602, a first end of the topological branch 602 is connected to the first end of the second voltage-dividing resistor R2, a second end of the topological branch 602 is connected to the power conversion chip 402, and a third end of the topological branch 602 is grounded. Specifically, the power conversion chip 402 is a converter of a buck topology structure, and the topological branch 602 is provided to assist the function of the power conversion chip 402, so that freewheeling and energy storage can be achieved when the switch of the power conversion chip 402 is disconnected.

[0077] Alternatively, if Figure 6 As shown, the topological branch 602 includes an inductor L1 and a diode D1, the first end of the inductor L1 is connected to the power conversion chip 402 and the output end of the diode D2, the second end of the inductor L1 is connected to the first end of the second voltage-dividing resistor R2, and the input end of the diode D2 is grounded. Among them, the inductor L1 realizes energy storage, and its model and parameters are selected according to actual needs; the diode D1 realizes freewheeling, and its model is a fast recovery diode.

[0078] like Figure 6 As shown, the power conversion chip 402 is an IC chip U1, which has four pins, wherein pin 1 is connected to the power supply voltage Vin, pin 2 is connected to the topological branch 602, pin 3 is grounded, and pin 4 is connected to the voltage divider circuit 404 to output the regulated voltage. The four voltage divider resistors in the voltage divider circuit 404 can perform voltage division operations on the connected regulated voltage and the adjustment signal to obtain the applied voltage Vout output. For ease of understanding, the design process of the voltage divider circuit 404 is shown in the following embodiment:

[0079] The applied voltage Vout and the regulating signal are considered as independent voltage sources. Figure 6 Using the circuit superposition theorem, the following formula can be obtained for the circuit structure shown:

[0080] (1)

[0081] Among them, V4 is the regulated voltage output by pin 4 of the IC chip U1, which is a fixed value determined according to the model structure of the IC chip U1.

[0082] Assuming V4=1.25V, Vpwm can take values ​​between 0V and 5V (determined by the power supply voltage of the beauty device), the duty cycle D of Vpwm ranges from 0% to 100%, the frequency is selected as 10K Hz, and the required Vout value range is set between 0V and 12V to achieve stepless output.

[0083] When Vpwm=0V, Vout=12V, then according to formula (1) we can get:

[0084] (2)

[0085] When Vpwm=5V, Vout=0V, then according to formula (1) we can get:

[0086] (3)

[0087] Combining formula (2) and formula (3), we can get (R3+R4) / R2=5 / 12, then we can take R2=20K ohms, then R3+R4=8.33K ohms; take R3=R4, then R3=R4=4.165K ohms. Considering the application of the resistance value of the resistor in the actual circuit, we can design R3=R4=4.3K ohms. Then substitute the calculated values ​​of R2, R3 and R4 into formula (2), we can calculate R1=3.18K ohms, according to the actual application, design R1=3.2K ohms.

[0090] By adjusting the different duty cycles of the signal, Vout can be controlled to output different voltage values. The voltage output is not limited to a few gears. The output voltage can correspond to the skin information of the target object to achieve accurate beauty.

[0091] In order to increase the transmission stability of the adjustment signal, in one embodiment, as Figure 6 As shown, the voltage divider circuit 404 also includes a filter capacitor C1, one side of the filter capacitor C1 is connected to the second end of the fourth voltage divider resistor R4 and the first end of the third voltage divider resistor R3, and the other side of the filter capacitor C1 is grounded. The filter capacitor C1 and the third voltage divider resistor R3 form a first-order filter circuit, which can filter the adjustment signal and improve the control accuracy of the adjustment signal.

[0092] In this embodiment, the voltage output of the action voltage is generated based on the adjustment signal and the regulated voltage according to the power conversion chip 402 and the voltage divider circuit 404. The different action voltages can be adjusted steplessly by changing the duty cycle of the adjustment signal. The output is not limited to the gear voltage. Different action voltages are suitable for different action objects, thereby improving the applicability of the beauty device.

[0093] In one embodiment, the beauty device further includes a current generating circuit, which is connected to the voltage regulating circuit 106 and is used to generate an action current based on the action voltage.

[0094] Specifically, the current generating circuit can receive the action voltage and generate the corresponding action current based on the action voltage. The current generating circuit can also generate different types of action currents, such as EMS microcurrent, radio frequency current, pulse current, etc. Among them, radio frequency current promotes the reorganization and regeneration of skin tissue by heating, mainly acting on the dermis to tighten the skin; pulse current is another mode of radio frequency, which mainly breaks up the pigment particles on the surface and deep layers of the skin through the principle of photothermal, which can brighten the skin tone; EMS microcurrent can stimulate motor nerves and muscle contraction through gentle and soft low-frequency waves, thereby stimulating facial muscle vitality and eliminating skin edema. The beauty equipment can generate different types of currents according to different operating modes or different needs of the object of action to achieve beauty massage.

[0095] In this embodiment, a current generating circuit is provided to output different types of action currents to meet different beauty needs of users and improve the applicability of the beauty device.

[0096] Based on the same technical concept, the present application also provides a beauty device control method, which can be applied to Figure 1 In the beauty device shown. In an exemplary embodiment, as Figure 7 As shown, a beauty device control method is provided, and the method is applied to Figure 1 The controller 104 in the example is used for explanation, and the steps include the following steps 702 to 704.

[0097] Step 702, obtaining skin information of the subject.

[0098] Wherein, the skin information is obtained by the skin detection circuit. The skin detection circuit contacts the skin of the subject, and can obtain the skin information of the subject through the circuit structure set therein, such as the impedance of the skin of the subject. Optionally, the skin detection circuit can be determined according to the value of the circuit parameter by passing a tiny current (the tiny current is smaller than the current generated by the beauty device during beauty massage) through the skin of the subject, and detecting the value of the circuit parameter at the same time; or it can be obtained by setting a device capable of scanning or detecting the skin surface of the subject in the skin detection circuit, and obtaining the output of the device as the output of the skin detection circuit to obtain the skin information of the subject. Specifically, the controller is connected to the skin detection circuit, and can obtain the skin information of the subject output by the skin detection circuit.

[0099] Step 704: outputting a regulating signal to a voltage regulating circuit based on the skin information.

[0100] The voltage regulating circuit is used to output a corresponding action voltage based on the adjustment signal. The voltage regulating circuit can convert the adjustment signal into an action voltage, and directly output the action voltage to the action object by directly contacting the skin of the action object, so as to perform a beauty massage on the action object. Alternatively, the beauty massage can also be achieved by contacting the skin of the action object with the massage component.

[0101] Specifically, the controller is connected to the skin detection circuit, can obtain skin information, and outputs an adjustment signal to the voltage regulation circuit according to the skin information analysis. Exemplarily, the gear of the beauty device is divided into high gear and low gear, and the controller can obtain the gear of the beauty device. Then, when the skin information of the object of action is the same, when the gear of the beauty device is high gear, the action voltage corresponding to the adjustment signal output by the controller is higher; when the gear of the beauty device is low gear, the action voltage corresponding to the adjustment signal output by the controller is lower.

[0102] Furthermore, in an exemplary embodiment, Figure 8 As shown, step 704 includes steps 802 to 804 .

[0103] Step 802, determining a theoretical output voltage based on the skin information and the regulated voltage.

[0104] Among them, the regulated voltage is obtained based on the power conversion chip of the voltage regulating circuit. The voltage regulating circuit includes a power conversion chip and a voltage divider circuit. The power conversion chip receives the power voltage of the beauty device, converts the voltage, and outputs the regulated voltage to the voltage divider circuit. Specifically, the controller needs to output an adjustment signal to the voltage divider circuit according to the skin information, and the action voltage is jointly adjusted by the adjustment signal and the regulated voltage. The controller needs to obtain the regulated voltage first, that is, the controller is connected to the power conversion chip, and obtains the regulated voltage output by the power conversion chip. The controller calculates the action voltage that needs to be output theoretically, that is, the theoretical output voltage, based on the obtained skin information and the conversion relationship between the regulated voltage and the voltage divider circuit to the action voltage (such as the formulas in the above embodiments).

[0105] Step 804, determining a corresponding regulation signal according to the theoretical output voltage, and outputting the signal to the voltage regulation circuit.

[0106] Specifically, after the controller obtains the theoretical output voltage through calculation, it determines the corresponding duty cycle, that is, the corresponding adjustment signal, according to the relationship between the theoretical output voltage and the duty cycle of the adjustment signal (see the example in the above embodiment). After obtaining the corresponding adjustment signal, the controller outputs the adjustment signal to the voltage divider circuit of the voltage regulation circuit, and the voltage divider circuit completes the output of the applied voltage.

[0107] In this embodiment, the output adjustment signal is controlled by first calculating the theoretical output voltage, which is beneficial to ensuring the accuracy of the adjustment signal, so that the subsequent voltage regulation circuit can output an accurate operating voltage, thereby improving the accuracy of the beauty device.

[0108] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0109] In one embodiment, the beauty device includes a skin detection circuit, a controller and a voltage regulating circuit, wherein the skin detection circuit is Figure 3 As shown, the voltage regulation circuit is as Figure 6 As shown, it has been recorded above and will not be repeated here. The beauty device can be a beauty instrument, which also includes a massage component, which is used to contact the skin and has metal electrodes distributed thereon, including six positive metal electrodes and four negative metal electrodes. The beauty instrument also includes an EMS microcurrent generating circuit, which can output EMS microcurrent to the massage component for achieving beauty massage.

[0110] The target is the user. The better the user's skin is, the smaller the skin resistance is, and the smaller the stimulation can be accepted. The voltage needs to be controlled to be small to avoid irritating the user. During use, the beauty instrument is first turned on, the user touches the skin, and the impedance acquisition module (skin detection circuit) detects the skin impedance value and transmits it to the AD port of the controller.

[0111] If the voltage collected by the AD port is 1.56V, the user's skin impedance is detected as R=U / I=(5V-1.56V) / (1.56V / 0.68MΩ)=1.499MΩ. According to the above formula and the numerical relationship between the duty cycle D and the applied voltage Vout, the adjustment signal output by the controller needs to be slowly adjusted from the duty cycle D=1 to D=0, and the corresponding applied voltage slowly rises from 0.34V to 11.97V. If the voltage collected by the AD port is 2.02V, the user's skin impedance is detected as R=U / I=(5V-2.02V) / (2.02V / 0.68MΩ)=1.00MΩ. According to the above formula and the numerical relationship between the duty cycle D and the applied voltage Vout, the adjustment signal output by the controller needs to be slowly adjusted from the duty cycle D from 1 to 0.24, and the corresponding applied voltage slowly rises from 0.34V to 9.18V.

[0112] The controller collects this impedance value (skin information) and outputs a PWM signal (regulation signal) based on this impedance value. The PWM signal can be controlled to slowly increase from the duty cycle D, and the corresponding action voltage output by the voltage regulation circuit can be slowly increased to prevent the voltage from being in place all at once and over-stimulating the skin. If the collected impedance changes at this time, the corresponding action voltage is dynamically output. The action voltage is input into the EMS micro-current generating circuit and then output to the beauty instrument guide head. In this way, the current output to the user's skin can be controlled to prevent excessive current stimulation and improve the applicability of the beauty instrument.

[0113] In this embodiment, the skin detection circuit detects skin information, and then outputs a corresponding adjustment signal to control the voltage regulating circuit to achieve stepless voltage regulation of the applied voltage, thereby providing stepless voltage beauty care for the user's skin. In this way, the current applied to the skin can change the speed and magnitude of the current with the control, matching the user's skin characteristics, being suitable for different groups of people, and improving the applicability of the beauty instrument.
