However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0049] See also Figures 1 to 3 As shown, an embodiment of the present application provides a beauty instrument 10, which includes a shell (not shown in the figure), a light source assembly 200 and a cold compress assembly (not shown in the figure). Under the action of the light source assembly 200 and the cold compress assembly, the beauty instrument 10 can not only care for the user's skin, but also apply a cold compress to the user's beauty area to be treated, so as to obtain dual effects and enhance the user experience.

[0050] In some embodiments of this application, see Figure 1 As shown, the housing is provided with a light outlet 110 and a receiving space (not shown in the figure). The receiving space can be connected to the outside through the light outlet 110. The light outlet 110 can be circular, square or other shapes.

[0051] In some embodiments of this application, see Figure 2As shown, the light source assembly 200 is arranged in the accommodating space. The light source assembly 200 includes a lamp board 210 and LED lamp beads 220 arranged in an array on the lamp board 210. The lamp board 210 can be circular, square or other shapes; the LED lamp beads 220 can be arranged in a rectangular array or a ring array on the lamp board 210. The power of each LED lamp bead 220 is greater than or equal to 0.5 watts. The multiple LED lamp beads 220 arranged in an array on the lamp board 210 correspond to the light outlet 110. The LED lamp beads 220 can emit light for beauty treatment. The light can pass through the light outlet 110 and be emitted to the part of the user to be beauty-treated. By having multiple LED lamp beads 220 correspond to the light outlet 110, the amount of light emitted from the light outlet 110 can be increased, thereby increasing the light output brightness and irradiation area of ​​the beauty instrument 10. In some other examples, the power of some of the LED lamp beads is greater than or equal to 0.5 watts.

[0052] As one aspect of the present application, by using LED lamp beads 220 with a power of 0.5 watts or more, high-energy light can be emitted without setting up a voltage converter, thereby reducing the use of voltage converters. Since the use of voltage converters of up to hundreds or thousands of volts is reduced, there is no need for specific high-voltage isolation, which simplifies the complexity of the internal driving circuit of the beauty instrument 10.

[0053] Of course, the present application is not limited to the use of high-power LED lamp beads 220. By arranging multiple LED lamp beads at positions corresponding to the light outlet 110 on the lamp board 210, the multiple beams of light emitted by the LED lamp beads 220 are superimposed and concentrated to be emitted through the light outlet 110, which can greatly increase the light energy of the light outlet 110. At this time, a single LED lamp bead 220 can use a power of less than 0.5 watts. As an example, a plurality of LED lamp beads are arranged on the lamp board 210, and all LED lamp beads are located within the positive projection range of the light outlet 110 on the lamp board 210, or at least more than 80% of the lamp beads are within this range. In addition, by adding energy storage capacitors to the LED lamp bead drive control circuit, the LED lamp beads 220 are illuminated in an instantaneous high-voltage, high-current pulse flash mode, which can achieve high-energy photon beauty during the skin exposure period. This part can be described later.

[0054] By arranging multiple LED lamp beads on the light board 210 directly opposite the light outlet, or further combining the use of a single high-power lamp bead, and using a large-capacity energy storage capacitor to discharge the LED lamp bead 220 to provide instantaneous flash high energy, the beauty instrument 10 using LED as the light source can obtain high-energy light output and a simple circuit structure. As an example, the beauty instrument 10 obtained by using the solution of the present application can have a total power of LED lamp beads of more than 15W, or the light power density of the beauty instrument 10 is between 2.5W and 100W / cm 2 , or when the light outlet 110 is placed against the skin, it generates 1J to 16J / cm2 energy.

[0055] In some embodiments of this application, see Figure 1 and Figure 2 As shown, the cold compress assembly is disposed in the accommodation space, located on one side of the light-emitting direction of the LED lamp bead 220. The cold compress assembly has a contact surface 321 for contacting the skin. Light emitted by the LED lamp bead 220 passes through the cold compress assembly and acts on the user's beauty area. The contact surface 321 of the cold compress assembly then applies a cold compress to the user's beauty area, thereby achieving dual benefits for both skin care and the beauty area, enhancing the user experience.

[0056] This application solution arranges multiple LED lamp beads 220 on the light board 210 at positions corresponding to the light outlet 110, so that the multiple beams of light emitted by the LED lamp beads 220 are superimposed and concentrated and emitted through the light outlet 110, which can significantly increase the light energy of the light outlet 110. The LED lamp beads 220 can emit high-energy light in normal lighting mode or high-voltage pulse flash mode at the moment of energy storage capacitor discharge without complex high-voltage conversion circuits. In addition, the cold compress component can be used to apply a cold compress to the user's beauty area while caring for the user's skin, thereby achieving dual benefits and improving the user experience.

[0057] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the cold compress assembly includes a stacked cooling element 310 and a cold compress 320. The cooling element 310 can be annular, strip-shaped, or any other shape, as long as it cools the cold compress 320 while avoiding blocking the light emitted by the LED lamp beads 220. The cooling element 310 is located on the side of the cold compress 320 near the light source assembly 200. The cold compress 320 has a contact surface 321 and a conductive surface 322. The conductive surface 322 and the contact surface 321 are respectively located on opposite sides of the cold compress 320. Specifically, one side of the cold compress 320 is the contact surface 321, and the other side is the conductive surface 322. The contact surface 321 is intended to contact the user's area to be treated, while the conductive surface 322 is in contact with one side of the cooling element 310. The cooling element 310 reduces the temperature of the cold compress 320, allowing the cold compress 320 to quickly cool the skin surface, reducing heat transfer to the skin and thereby reducing burning and stinging sensations.

[0058] It should be noted that the cold compress 320 can be made of a material with good light transmittance and thermal conductivity, such as sapphire (Al2O3), quartz, or K9 glass. By using a cold compress 320 with good light transmittance and thermal conductivity, it can avoid blocking the light emitted by the LED lamp beads 220, ensuring the maximum amount of light emitted, and ensure that the cooling element 310 can quickly cool the cold compress 320, thereby quickly cooling the skin surface and reducing heat transfer to the skin, thereby improving the user experience.

[0059] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the cooling element 310 can be a semiconductor cooling sheet. When powered on, the cooling element 310 can form a cold surface 311 and a hot surface 312. The cold surface 311 is used to cool the cold compress 320, gradually reducing the temperature of the cold compress 320.

[0060] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the beauty device 10 further includes a driver circuit board 400, which is connected to the light source assembly 200 and the cooling element 310. The driver circuit board 400 can control the LED lamp beads 220 in the light source assembly 200 to turn on or off, and can also control the cooling element 310 to generate a cold surface 311 and a hot surface 312. The driver circuit board 400 includes a first electrode (not shown in the figure) and a second electrode (not shown in the figure). For example, the first electrode is a positive electrode and the second electrode is a negative electrode.

[0061] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the cooling element 310 includes a first connection port 313 and a second connection port 314, and the first connection port 313 and the second connection port 314 are electrically connected to the first electrode and the second electrode, respectively. The first electrode transmits current to the first connection port 313, the current flows through the cooling element 310 and flows out from the second connection port 314, and finally the current flows back to the second electrode, forming a current loop. During the flow of current, the two opposite sides of the cooling element 310 form a cold surface 311 and a hot surface 312, respectively. The cold surface 311 corresponds to the conductive surface 322 of the cold compress 320 to absorb the heat of the cold compress 320 and quickly reduce the temperature on the cold compress 320.

[0062] For example, the cooling element 310 includes a first ceramic sheet, a second ceramic sheet, a P-type semiconductor, an N-type semiconductor, a first guide bar, and a second guide bar. The P-type semiconductor, the N-type semiconductor, the first guide bar, and the second guide bar are disposed between the first and second ceramic sheets. The first ceramic sheet is provided with a first guide bar, and the second ceramic sheet is provided with two second guide bars spaced apart from each other. One end of the P-type semiconductor and the N-type semiconductor are connected to the first guide bar, and the other ends of the P-type semiconductor and the N-type semiconductor are respectively connected to two different second guide bars. The first connection port 313 is connected to a second guide bar, and the second connection port 314 is connected to another second guide bar. When the first connection port 313 releases current, the current flows sequentially through the second guide bar, the N-type semiconductor, the first guide bar, the P-type semiconductor, and the second guide bar, and ultimately flows back into the second connection port 314, forming a current loop. When current flows through the P-type semiconductor and the N-type semiconductor, the first ceramic sheet absorbs heat and the second ceramic sheet releases heat, respectively, so that the first ceramic sheet and the second ceramic sheet form a cold surface 311 and a hot surface 312, respectively.

[0063] It is understandable that, in order to achieve rapid cooling, the cooling element 310 may use a plurality of P-type semiconductors and N-type semiconductors, so as to increase the cooling effect on the cold compress element 320 .

[0064] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the cold compress assembly further includes a conductive element 330 to promptly transfer the heat from the hot surface 312 of the refrigeration element 310 to cool the hot surface 312 of the refrigeration element 310 .

[0065] In some embodiments of this application, please continue to refer to Figure 2 and Figure 3As shown, the conductive member 330 includes a conductive plate 331 and a conductive tube 332. The conductive plate 331 and the conductive tube 332 can be annular, bar-shaped, or in other shapes, as long as they can transfer heat and prevent the light emitted by the LED lamp beads 220 from being blocked. Among them, one side of the conductive plate 331 is in contact with the hot surface 312 of the refrigeration element 310 to absorb the heat generated by the hot surface 312. The conductive plate 331 can be made of a material with good thermal conductivity, such as copper, aluminum, etc., so that the heat on the refrigeration element 310 can be transferred out in a timely manner. The conductive tube 332 is arranged on the side of the conductive plate 331 away from the refrigeration element 310 to transfer the heat on the conductive plate 331. The conduction tube 332 includes a tube body 3320 and a heat dissipation portion 3321. The tube body 3320 is attached to the side of the conduction plate 331 away from the refrigeration element 310. At least one heat dissipation portion 3321 is provided at the end of the tube body 3320. The heat dissipation portion 3321 extends toward the side away from the conduction plate 331. The heat on the hot surface 312 of the refrigeration element 310 is gradually transferred through the conduction plate 331, the tube body 3320 and the heat dissipation portion 3321.

[0066] For example, the tube body 3320 includes two ends spaced apart from each other. A heat sink 3321 is provided at each end of the tube body 3320. The heat sink 3321 gradually removes heat from the tube body 3320. The two heat sinks 3321 increase heat transfer and improve the efficiency of heat conduction to the conductive plate 331, thereby more quickly reducing the temperature of the hot surface 312 of the refrigeration element 310.

[0067] It should be noted that the conductive tube 332 may also be made of a material with good thermal conductivity, such as copper, aluminum, etc., to quickly take away the heat from the conductive plate 331 .

[0068] In some embodiments of the present application, the beauty instrument 10 further includes a radiator (not shown in the figure). The radiator is disposed in the accommodation space and is connected to the heat dissipation portion 3321 on the conductive tube 332 to gradually remove heat from the heat dissipation portion 3321.

[0069] It is understandable that the radiator may adopt air cooling, water cooling or other cooling methods, as long as it can cool the heat dissipation portion 3321.

[0070] In some embodiments of the present application, the radiator is cooled by air. Figure 4As shown, the radiator includes a cooling fan (not shown) and a plurality of heat dissipation fins 500 arranged in sequence and spaced apart. The heat dissipation portion 3321 passes vertically through all the heat dissipation fins 500 in sequence to connect with each heat dissipation fin 500. The heat dissipation portion 3321 can release heat to each heat dissipation fin 500. The cooling fan is located to the side of the heat dissipation fins 500 or below the heat dissipation fins 500. The cooling fan releases cooling air to the heat dissipation fins 500, and the cooling air gradually removes the heat from the heat dissipation fins 500.

[0071] That is to say, the heat on the hot surface 312 of the refrigeration element 310 is gradually dissipated through the conduction plate 331, the tube body 3320, the heat dissipation portion 3321 and the heat dissipation fins 500, thereby gradually reducing the temperature of the hot surface 312 of the refrigeration element 310 to ensure the internal temperature of the beauty instrument 10 is stable.

[0072] Understandably, see Figure 2 and Figure 3 As shown, in order to facilitate the discharge of the air that absorbs heat, a vent 120 is further provided on the shell. The cooling air absorbs the heat on the heat dissipation fins 500 and is discharged through the vent 120 to avoid the cooling air remaining inside the accommodation space and causing the temperature inside the beauty instrument 10 to rise, thereby ensuring that the internal components of the beauty instrument 10 operate in a normal temperature environment.

[0073] In addition, see Figure 1 As shown, to prevent foreign matter from falling into the storage space, the beauty device 10 further includes a cover plate 600. The cover plate 600 is provided with a plurality of ventilation windows, which can discharge cooling air after absorbing heat. The cover plate 600 can be connected to the housing by threads or by snap fasteners.

[0074] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the beauty instrument 10 further includes a contact sensor 700. The contact sensor 700 can be disposed inside the accommodation space or outside the housing, as long as it can detect contact between the beauty instrument 10 and the skin.

[0075] In some embodiments of the present application, the contact sensor 700 is disposed within the accommodating cavity and can be annular, strip-shaped, or other shapes to avoid blocking the light emitted by the LED lamp beads 220. The contact sensor 700 is disposed between the cold compress 320 and the refrigeration element 310. One surface of the contact sensor 700 is in contact with the conductive surface 322 of the cold compress 320, and the other surface of the contact sensor 700 is in contact with the cold surface 311 of the refrigeration element 310. The refrigeration element 310 cools the cold compress 320 through the contact sensor 700.

[0076] It is understandable that in order to prevent the contact sensor 700 from affecting the cooling effect of the cooling element 310 on the cold compress element 320, the contact sensor 700 is made of a thinner material with better thermal conductivity.

[0077] In addition, the contact sensor 700 is electrically connected to the driving circuit board 400. The contact sensor 700 can generate a control signal when the contact surface 321 contacts the user's skin, and transmit the control signal to the driving circuit board 400. The driving circuit board 400 can control the LED lamp beads 220 to emit light and / or control the refrigeration component 310 to form a hot surface 312 and a cold surface 311 according to the control signal. It can not only control the LED lamp beads 220 to emit light and the refrigeration component 310 to form a hot surface 312 and a cold surface separately, but also control the LED lamp beads 220 to emit light and control the refrigeration component 310 to form a hot surface 312 and a cold surface at the same time.

[0078] When the LED lamp beads 220 are controlled to emit light and the refrigeration component 310 is controlled to form a hot surface 312 and a cold surface at the same time, the refrigeration component 310 can work synchronously while the LED lamp beads 220 are emitting light, avoiding delays in the operation of the cold compress 320, ensuring that the cold surface 311 of the refrigeration component 310 continues to cool the cold compress 320, and ensuring that the temperature of the cold compress 320 is maintained at a low level.

[0079] In some embodiments of this application, please continue to refer to Figure 2 and Figure 3 As shown, the beauty instrument 10 also includes a support frame 800. The support frame 800 is annular, and one end of the support frame 800 is covered by the light source assembly 200, so that the light source assembly 200 is located within the support frame 800. The support frame 800 includes a support body 810 and an annular boss 820 protruding from the support body 810. The support body 810 is arranged around the outer edge of the light board 210; the annular boss 820 is arranged on the side of the support body 810 near the light outlet 110. The cooling element 310, the conductive element 330, and the contact sensor 700 are sleeved on the outside of the annular boss 820, thereby supporting and fixing the cooling element 310, the conductive element 330, and the contact sensor 700. In addition, the conductive surface 322 of the cold compress 320 is covered on the side of the annular boss 820 away from the support body 810, so as to ensure that the light emitted by the LED lamp bead 220 can completely pass through the cold compress 320 and be emitted from the light outlet 110, avoiding the problem of light leakage and light waste. Through this support frame 800, the amount of light can be increased and the brightness of the light output can be improved.

[0080] In some embodiments of this application, see Figures 4 to 6As shown, the beauty device 10 also includes a heat sink 900 and a cooling fan (not shown). The heat sink 900 is located on the side of the light board 210 away from the LED lamp beads 220 to reduce the heat generated by the light board 210 and the LED lamp beads 220. The heat sink 900 includes a heat sink 910 and heat sink fins 920. The heat sink 910 is attached to the light board 210 to transfer heat from the light board 210 to the heat sink 910. A plurality of heat sink fins 920 are arranged in an array on the side of the heat sink 910 away from the light board 210. The cooling fan is located within the accommodation space and can release a flow of cold air toward the heat sink 900 to remove heat from the heat sink 920 and the heat sink 910, thereby cooling the heat sink 910 and the heat sink 920. The heat sink 900 and the heat sink 900 gradually remove the heat released by the light board 210 and the LED lamp beads 220, ensuring that the LED lamp beads 220 are maintained at a normal operating temperature.

[0081] Understandably, see Figure 3 As shown, in order to allow the cold air that absorbs heat to be discharged from the accommodation space in time, the shell is further provided with an air outlet 130, and the cold air is discharged to the outside through the air outlet 130.

[0082] See also Figure 2 and Figure 3 As shown, in order to prevent impurities from entering the beauty device 10, the beauty device 10 further includes a back cover 1000, which is provided at the air outlet 130. The back cover 1000 can be detachably connected to the housing by means of a buckle or screws, so that the back cover 1000 can be easily replaced or opened to clean impurities in the air outlet 130 in a timely manner.

[0083] It is worth mentioning that there is no filter in the present application solution, so there will be no filter to filter out the light in the main band or the peak band, thereby ensuring the light utilization rate of the LED lamp bead 220.

[0084] In some embodiments of the present application, the beauty instrument 10 may further include a filter (not shown in the figure). The filter can be provided on the side of the cold compress 320 close to the light source assembly 200, that is, the light emitted by the LED lamp beads 220 is pre-filtered by the filter before being emitted through the cold compress 320. The filter can filter out light outside the required wavelength band, and under the action of the cold compress 320, the heat generated by the intercepted light can be reduced. In other words, by using the filter and the cold compress 320, it is possible to ensure that the temperature is normal while obtaining the light of the required wavelength band.

[0085] In some embodiments of this application, see Figure 2 and Figure 3As shown, the housing includes a front shell 140, an inner shell 150 and a rear shell 160. A receiving space is formed between the front shell 140 and the rear shell 160. The inner shell 150 is disposed between the front shell 140 and the rear shell 160, and the light source assembly 200 and the cold compress assembly are both arranged on the inner shell 150.

[0086] In some embodiments of this application, please continue to refer to Figure 2 and Figure 3 As shown, the front shell 140 is snap-fitted to the rear shell 160. The outer edge of the front shell 140 is provided with a plurality of outwardly protruding first lugs 141, and the inner sidewall of the rear shell 160 is provided with a plurality of snap-fit ​​portions 161. The snap-fit ​​portions 161 correspond to the first lugs 141, and the first lugs 141 snap-fit ​​onto the snap-fit ​​portions 161. A first groove is provided at the top of the front shell 140, and a second groove is provided at the top of the rear shell 160. The first groove corresponds to the second groove. When the front shell 140 and the rear shell 160 are snap-fitted together, the aforementioned vent 120 is formed. The inner wall of the vent 120 is provided with a recessed portion, and the cover plate 600 snaps into the recessed portion.

[0087] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the light source assembly 200 is mounted on the side of the inner housing 150 near the front housing 140, and the light board 210 is attached to the outer wall of the inner housing 150. Through-holes are provided in the inner housing 150 at positions corresponding to the light board 210. A heat sink 910 and a cooling fan are mounted within the inner housing 150. The heat sink 910 is connected to the side of the light board 210 away from the LED lamp beads 220 via the through-holes, and the cooling fan is mounted within the inner housing 150 via a fan mounting portion. By locating the cooling fan and heat sink 910 within the inner housing 150, the arrangement of components within the housing is optimized, making the interior of the beauty device 10 more compact. Furthermore, an air vent is provided on the back of the inner housing 150, through which cool air, which removes heat from the heat sink 920, flows out, lowering the temperature within the inner housing 150 and ensuring a stable temperature within the beauty device 10.

[0088] In some embodiments of this application, see Figure 2 As shown, a protruding buckle 151 and a plurality of limiting protrusions 152 are provided on the outer wall of the inner shell 150 on the side close to the front shell 140. The buckle 151 and the limiting protrusions 152 are spaced apart from each other. A second lug 811 is provided on the outer edge of the support body 810. The second lug 811 engages with the buckle 151 of the inner shell 150. The outer edge of the support body 810 abuts against the limiting protrusions 152, so that the support body 810 is locked into the limiting space formed by the plurality of limiting protrusions 152, so that the support body 810 is arranged around the light board 210.

[0089] In some embodiments of the present application, part of the heat dissipation portion 3321, the heat dissipation fins 500 and the cooling fan are also arranged in the inner shell 150 to dissipate heat from the heat dissipation portion 3321, and optimize the internal space of the beauty instrument 10, making the interior of the beauty instrument 10 more tidy and conducive to circuit layout.

[0090] In some embodiments of this application, see Figure 5 and Figure 6 As shown, the beauty instrument 10 also includes an energy storage capacitor 1100 and a power module 1200. The power module 1200 is electrically connected to the energy storage capacitor 1100 through the interface module circuit board. The power module 1200 can be electrically connected to an external power supply to charge the energy storage capacitor 1100. The energy storage capacitor 1100 is electrically connected to the driver circuit board 400. The energy storage capacitor 1100 can release voltage to the LED lamp beads 220. The energy storage capacitor 1100 is used to release voltage to the LED lamp beads 220 to increase the driving voltage to obtain the LED flash beauty effect. It can be understood that in the flash mode, the energy storage capacitor 1100 is used to control the LED lamp beads 220 to produce the flash effect, and the voltage converter in the xenon lamp tube is not used. The driving circuit inside the beauty instrument 10 does not involve ultra-high voltage lines, which makes the circuit inside the beauty instrument 10 more simple.

[0091] In some embodiments of this application, see Figure 3 As shown, the driving circuit board 400 includes a first circuit board 410 and a second circuit board 420. The first circuit board 410 is electrically connected to the energy storage capacitor 1100, the light source assembly 200, the contact sensing module and the refrigeration component 310. The second circuit board 420 is electrically connected to the first circuit board 410, and a button is provided on the second circuit board 420. The circuit signal on the first circuit board 410 can be controlled by the button to control the working mode in the light source assembly 200 or control the refrigeration component 310 to work, etc.

[0092] Please refer to further Figure 7The first circuit board 410 is also provided with an LED lamp bead drive control circuit. A plurality of lamp beads LED1 to LEDn are connected in series to form a light-emitting unit, and the energy storage capacitor C1 is connected to the LED lamp bead and the power supply voltage to provide the LED lamp bead with the energy required for high-power light emission. In a specific example, the first end of the energy storage capacitor 1100 is electrically connected to the anode of the light-emitting unit and connected to the power supply voltage VIN, and the second end of the energy storage capacitor C1 is grounded. A certain amount of electricity can be stored through the energy storage capacitor C1. When performing beauty lighting, the electricity stored in the energy storage capacitor C1 can be released to the light-emitting unit to enable the LED to generate a pulsed high-power flash, so that the flash instantly generates high-energy light to irradiate the skin. The lamp bead drive control circuit also includes a PWM controller, an NMOS switch tube Q1, a freewheeling diode D2, a choke inductor L1, a current feedback resistor R4, and a filter stabilizing capacitor C4. Among them, the gate of the NMOS switch tube Q1 is electrically connected to the PWM control signal, the source of the NMOS switch tube Q1 is grounded through the current feedback resistor R4, and the source of Q1 is connected to the feedback end of the PWM controller. The PWM control signal turns the switch 1 on or off, thereby controlling the conduction of the LED light-emitting unit circuit, thereby controlling the lighting. By outputting PWM control signals with different frequencies and duty cycles, the frequency, brightness, and other parameters of the LED lighting can be controlled. A freewheeling diode D2 is connected in reverse order between the anode of the light-emitting unit and the drain of the NMOS switch Q1, and a choke inductor L1 is connected between the cathode of the light-emitting unit and the drain of the NMOS switch Q1. The freewheeling diode D2 and choke inductor L1 form a freewheeling circuit that provides a delayed current to the light-emitting unit when the NMOS switch Q1 is off, thereby improving the stability and service life of the light-emitting unit. A filtering and stabilizing capacitor C4 is connected to both ends of the light-emitting unit, forming a parallel connection with the LED beads. A protection circuit can also be included between the PWM control signal and the switch Q1. This protection circuit can include a resistor R1 and a diode D1. The resistor R1 and diode D1 are connected in parallel, with the anode of diode D1 connected to the gate (i.e., the control terminal) of the NMOS switch Q1 and the cathode of diode D1 connected to the PWM controller.

[0093] In other embodiments, the energy storage capacitor 1100 may include multiple capacitors, some of which may be used to power the aforementioned high-energy pulsed LED flash, while others may be used to power the beauty device's rechargeable battery. The light-emitting unit may also be a single LED lamp bead, or multiple LED lamp beads connected in series and parallel.

The beauty instrument 10 also includes a frame cover 1300, which is located on the rear housing 160 at the location of the air outlet 130 and can be fixed to the rear housing 160 using screws or rivets. The frame cover 1300 also has an outlet, and the rear cover 1000 is placed on the frame cover 1300 to cover the outlet, preventing impurities from falling into the air outlet 130 and ensuring the cleanliness of the interior of the beauty instrument 10.

[0095] In some embodiments of the present application, an opening is further provided on the rear shell 160 , through which the above-mentioned buttons are exposed, and a button shell is provided on the buttons to prevent damage to the buttons.

[0096] In some embodiments of this application, see Figure 2 As shown, the beauty instrument 10 further includes a bottom cover 1400, which is provided on the outer edges of the bottom of the front shell 140 and the rear shell 160 to further connect the front shell 140 and the rear shell 160 and ensure the stability of the connection between the front shell 140 and the rear shell 160. The bottom cover 1400 is provided with a charging port, which is exposed to the power module 1200. A charging cable is passed through the charging port to connect to the power module 1200 to supply power to the power module 1200.
