Description

Technical Field

[0001] This application belongs to the field of beauty equipment technology, specifically relating to a beauty instrument. Background Technology

[0002] With societal development, people are paying increasing attention to skin care and maintenance. Currently, a large number of photon beauty devices have appeared on the market. These devices use xenon lamps to emit strong pulsed light of specific wavelengths to achieve hair removal or skin rejuvenation effects. To improve the efficiency of these treatments, existing skin rejuvenation devices focus on increasing the frequency of the xenon lamp's flashes. However, frequent high-power flashes inevitably generate a large amount of heat. When this heat is transferred to the user's skin, it causes stinging and may even lead to burns. To cool the skin surface, some photon beauty devices now include a cooling component. This component absorbs the heat from the skin's surface and dissipates it outside the device through a heat dissipation system.

[0003] In current photon beauty devices, the xenon lamp tube and the cooling component share a heat dissipation system. Since the xenon lamp tube is the main heat source in the photon beauty device, sharing a heat dissipation system with the cooling component will prevent the heat absorbed by the cooling component from being quickly dissipated outside the photon beauty device, thus affecting the cooling effect of the cooling component. Utility Model Content

[0004] The purpose of this application is to solve the problems in the prior art, such as the xenon lamp tube and the cooling component sharing a heat dissipation system, which causes the heat absorbed by the cooling component to be unable to be quickly dissipated outside the photon beauty device, thus affecting the cooling effect of the cooling component.

The cooling pad is provided, and the light-transmitting cooling compress is arranged corresponding to the light outlet, so that the light emitted by the light-emitting element can pass through the light-transmitting cooling compress and be emitted from the light outlet; the light-transmitting cooling compress is provided with a contact surface that contacts the area to be treated; the heat dissipation assembly includes a first fan disposed in the first channel, a second fan disposed in the second channel, and a heat sink; the heat sink is connected to the cooling pad, so that the cooling pad transfers heat to the heat sink; the first fan can introduce external airflow into the first channel through the first air inlet to cool the light-emitting element; the second fan can introduce external airflow into the second channel through the second air inlet to cool the heat sink.

[0006] In one exemplary embodiment of this application, the air inlet end of the second fan faces the second air inlet, the first fan is disposed on the side of the second fan away from the second air inlet, and the first fan and the second fan are isolated from each other.

[0007] In one exemplary embodiment of this application, both the first fan and the second fan have an axial air intake and radial air exhaust structure, and the port of the first channel opposite to the first air inlet and the port of the second channel opposite to the second air inlet are arranged side by side.

[0008] In one exemplary embodiment of this application, the radiator is disposed on the side of the second fan near the second air inlet and is spaced apart from the second fan. The radiator is provided with a ventilation channel for external airflow to pass through, the ventilation channel being opposite to the second air inlet, and the external airflow flowing into the second fan through the ventilation channel.

[0009] In one exemplary embodiment of this application, the heat sink includes a plurality of heat dissipation fins spaced apart from each other, the heat dissipation fins extending along an external airflow path, and the ventilation channel forming between adjacent heat dissipation fins; the heat dissipation fins are connected to the cooling plate so that the cooling plate transfers heat to the heat dissipation fins.

[0010] In one exemplary embodiment of this application, the light-transmitting cooling device includes a conductive surface and a contact surface; the two opposite sides of the cooling sheet are a cold surface and a hot surface, respectively, the cold surface is attached to the conductive surface to cool the conductive surface, and the hot surface is connected to the heat dissipation fins, which can remove heat from the hot surface.

[0011] In one exemplary embodiment of this application, the beauty device further includes a heat pipe, one end of which is connected to the hot surface of the cooling chip, so that the heat from the hot surface of the cooling chip is transferred to the heat pipe, and the other end of which is connected to the heat dissipation fins, so that the heat from the heat pipe is transferred to the heat dissipation fins.

[0012] In an exemplary embodiment of this application, each of the heat dissipation fins has a mounting port on the side near the second air inlet, which opens toward the second air inlet. The mounting ports of multiple heat dissipation fins form a mounting position, and the heat pipe is embedded in the mounting position to release the heat on the heat pipe to the multiple heat dissipation fins.

[0013] In one exemplary embodiment of this application, the first air inlet and the second air inlet are located on different sides of the housing from the air outlet.

[0014] In one exemplary embodiment of this application, the light-transmitting cooling device includes a sapphire component, and the light-emitting component includes a xenon lamp tube.

[0015] In one exemplary embodiment of this application, the beauty device further includes an integrated housing disposed within the housing, wherein the first fan, the second fan, the first channel, and the second channel are integrated within the integrated housing.

[0016] The beauty device described in this application has at least the following beneficial effects:

[0017] The beauty device of this application includes a housing, a light-emitting element, a cooling assembly, and a heat dissipation assembly. The housing has a first channel and a second channel that are isolated from each other. The port of the first channel forms a first air inlet on the housing, and the port of the second channel forms a second air inlet on the housing. The ports of the first channel and the second channel opposite to the first air inlet are both connected to an air outlet. A first fan in the heat dissipation assembly is located in the first channel, and a second fan and a heat sink are located in the second channel. The heat sink is connected to a cooling plate in the cooling assembly to transfer heat from the cooling plate to the heat sink. Specifically, the first fan introduces external airflow into the first channel through the first air inlet to cool the light-emitting element, thereby reducing its temperature. The second fan introduces external airflow into the second channel through the second air inlet to cool the heat sink, allowing the heat sink to continuously absorb heat from the cooling plate, reducing its temperature and thus lowering the temperature of the light-transmitting cooling assembly, maintaining a continuous cooling effect on the contact surface of the light-transmitting cooling assembly. Because the second channel is isolated from the first channel, the light-emitting component and the cooling component use an independent heat dissipation system, which can prevent the hot air from the light-emitting component from interfering with the hot air from the cooling component. This ensures that the heat from the light-emitting component and the cooling component is quickly expelled from the beauty device casing, thus ensuring the cooling effect of the cooling component.

[0035] See Figure 1 As shown in the figure, this application provides a beauty device 10, which can perform anti-wrinkle, hair removal, skin rejuvenation, anti-inflammatory and acne-reducing effects, but is not limited to these.

[0036] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the beauty device 10 includes a housing 100 and a light-emitting element 200, a cooling component 300, and a heat dissipation component 400 disposed within the housing 100.

[0037] The housing 100 can define the overall shape of the beauty device 10, which can be round, oval, elongated or other shapes.

[0038] In some embodiments of this application, please refer to... Figure 2 and Figure 3 As shown, the housing 100 can be an internal cavity structure. The light-emitting element 200, the cooling component 300, and the heat dissipation component 400 can all be installed inside the housing 100 and fixed relative to the housing 100 to prevent the light-emitting element 200, the cooling component 300, and the heat dissipation component 400 from sliding or falling off, thus ensuring the stability of the light-emitting element 200, the cooling component 300, and the heat dissipation component 400 inside the housing 100.

[0039] In some embodiments of this application, the light-emitting element 200 can emit cosmetic light to the outside of the housing 100 to act on the user's area to be treated. The housing 100 may have a light-emitting port (not shown in the figure) to facilitate the passage of the cosmetic light emitted by the light-emitting element 200 for cosmetic treatment of the user's area.

[0040] It is worth mentioning that the light-emitting component 200 can use xenon lamp tubes, LED lamp beads, or other types of light-emitting devices, such as OLED lamps, halogen lamps, etc.

[0041] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the beauty device 10 also includes a reflector cup 500 and a filter 600. The filter 600 is positioned in the light-emitting direction of the light-emitting element 200. The filter 600 can filter the light emitted by the light-emitting element 200 to obtain corresponding beauty light, thereby achieving the corresponding beauty effect. The reflector cup 500 covers the light-emitting element 200 and is connected to the filter 600. The side of the reflector cup 500 facing the light-emitting element 200 has a reflective surface, so that the beauty light generated by the light-emitting element 200 can completely pass through the filter 600 and be directed to the light outlet, improving light utilization and ensuring the beauty effect.

[0042] In some embodiments of this application, see Figure 3 As shown, the cooling component 300 is located on the light emission path of the light-emitting component 200. It can provide skin care for the user while also providing a cooling treatment to the area to be treated, reducing the burning sensation on the area. This allows the beauty device 10 to achieve dual benefits and enhance the user experience.

[0043] In some embodiments of this application, see Figure 3 or Figure 4As shown, the cooling compress assembly 300 includes a light-transmitting cooling compress component 310. The light-transmitting cooling compress component 310 is located at the light outlet and is spaced apart from the light-emitting component 200 in the light emission direction. The light-transmitting cooling compress component 310 has a contact surface 311 for contact with the user's skin. The contact surface 311 is located at and flush with the light outlet to facilitate contact with the user's skin and ensure the cooling effect. The light-transmitting cooling compress component 310 can continuously cool the user's skin during the operation of the light-emitting component 200, reducing burning sensation and improving the user experience.

[0044] It should be noted that the translucent cooling compress 310 can be made of materials with good light transmittance and thermal conductivity, such as sapphire (Al2O3), quartz, or K9 glass. By using a translucent cooling compress 310 with good light transmittance and thermal conductivity, it is possible to avoid blocking the light emitted by the light-emitting element 200, ensuring the amount of light emitted, and also to ensure that the cooling plate 320 described below can quickly cool the translucent cooling compress 310, thereby rapidly cooling the skin surface, reducing heat transfer to the skin, and thus improving the user experience.

[0045] In some embodiments of this application, see Figure 3 and Figure 5 As shown, the cooling compress assembly 300 also includes a cooling pad 320. The cooling pad 320 is in contact with the conductive surface 312 of the light-transmitting cooling compress 310, and it can continuously remove heat from the light-transmitting cooling compress 310, thereby reducing the temperature of the light-transmitting cooling compress 310 and keeping the light-transmitting cooling compress 310 at a low temperature to maintain the cooling effect.

[0046] It should be noted that the refrigeration element 320 can be a semiconductor refrigeration element 320, or it can be a compression refrigeration element, absorption refrigeration element, etc.

[0047] In addition, see Figure 5 As shown, the conductive surface 312 of the light-transmitting cooling compress 310 can be provided on the side wall of the light-transmitting cooling compress 310 so as to be fitted and installed with the cooling pad 320.

[0048] In some embodiments of this application, the cooling chip 320 is a semiconductor cooling chip 320, which can form a cold surface (not shown in the figure) for absorbing heat and a hot surface (not shown in the figure) for releasing heat when energized. The cold surface is in contact with the conductive surface 312 of the light-transmitting cooling compress 310, and can gradually remove the temperature on the conductive surface 312, so that the light-transmitting cooling compress 310 can be kept at a low temperature, ensuring the cooling effect of the light-transmitting cooling compress 310.

[0049] In some embodiments of this application, see Figure 1 , Figure 2 and Figure 4As shown, the housing 100 also has a first channel 110 and a second channel 120 that are isolated from each other.

[0050] In other embodiments of this application, the port of the first channel 110 can form a first air inlet 130 on the housing 100, and the port of the second channel 120 can form a second air inlet 140 on the housing 100. That is, the port of the first channel 110 is connected to the housing 100, and the port of the second channel 120 is connected to the housing 100. The housing 100 is also provided with an air outlet 150, and the port of the first channel 110 opposite to the first air inlet 130 and the port of the second channel 120 opposite to the second air inlet 140 are both connected to the air outlet 150.

[0051] In some embodiments of this application, the port of the first channel 110 corresponds to the first air inlet 130, and the port of the second channel 120 corresponds to the second air inlet 140. That is, the port of the first channel 110 is spaced apart from the inner wall of the housing 100, and the port of the second channel 120 is spaced apart from the inner wall of the housing 100. Furthermore, the ports of the first channel 110 and the second channel 120 that are away from the first air inlet 130 correspond to the air outlet 150.

[0052] In some embodiments of this application, the heat dissipation assembly 400 can cool down the light-emitting element 200 in the first channel 110 to prevent the light-emitting element 200 from overheating and being damaged. In addition, the heat dissipation assembly 400 can also reduce the temperature of the hot surface of the cooling chip 320, thereby ensuring that the temperature inside the housing 100 is maintained within a safe range and ensuring the normal operation of the devices inside the housing 100.

[0053] In some embodiments of this application, see Figure 5 As shown, the heat dissipation assembly 400 includes a first fan 410 disposed in the first channel 110, a second fan 420 disposed in the second channel 120, and a heat sink 430.

[0054] Among them, see Figure 2 , Figure 3 and Figure 6 As shown, the first channel 110 is also equipped with a light-emitting element 200 and a reflector cup 500 covering the outside of the light-emitting element 200. The first fan 410 can introduce external airflow into the first channel 110 through the first air inlet 130 (see...). Figure 2 , Figure 3 and Figure 6 (The path diagram of the first ventilation path with the dashed line in the middle) uses external airflow to cool the light-emitting element 200, gradually removing the heat from the light-emitting element 200 and the reflector cup 500, reducing the temperature of the light-emitting element 200, and discharging the heat-absorbing air through the air outlet 150.

[0055] The radiator 430 is connected to the cooling fin 320, allowing heat from the cooling fin 320 to be transferred to the radiator 430. The second fan 420 can draw external airflow into the second channel 120 through the second air inlet 140 (see...). Figure 2 , Figure 3 and Figure 6 (The second ventilation path is shown in the middle dashed line diagram). The external airflow is used to cool the radiator 430, thereby reducing the heat of the hot surface of the cooling plate 320. The air that has absorbed the heat is discharged through the air outlet 150 to maintain the temperature inside the housing 100.

[0056] Understandably, by using the first channel 110 and the second channel 120, which are isolated from each other inside the housing 100, the light-emitting element 200 and the cooling component 300 can use a set of heat dissipation systems independently. This can prevent the hot air absorbing the heat from the light-emitting element 200 and the hot air absorbing the heat from the cooling component 300 from interfering with each other. It ensures that the airflow absorbing the heat from the light-emitting element 200 and the airflow absorbing the heat from the cooling component 300 can be quickly discharged outside the housing 100 of the beauty device 10, thus ensuring the cooling effect of the cooling component 300.

[0057] In some embodiments of this application, see Figure 1 As shown, the light outlet faces the user's area to be treated. The first air inlet 130 and the air outlet 150 are located on different sides of the housing 100 from the light outlet. The first air inlet 130 and the second air inlet 140 can be located on the same side of the housing 100 or on different sides, as long as the air outlet 150 is on a different side from the first air inlet 130 and the second air inlet 140. Having the air outlet 150 on a different side from the first air inlet 130 and the second air inlet 140 prevents the hot air discharged from the air outlet 150 from re-entering the first channel 110 and the second channel 120 through the first air inlet 130 and the second air inlet 140. This ensures that the external airflow temperature entering the first channel 110 and the second channel 120 is low, thereby ensuring effective heat dissipation for the light-emitting element 200 and the cooling assembly 300, and improving heat dissipation performance.

[0058] In some embodiments of this application, the first air inlet 130 and the second air inlet 140 may both be located on the bottom wall of the housing 100. The air outlet 150 is located on the side wall of the housing 100. By placing the air outlet 150 on the side wall of the housing 100, the hot air released from the air outlet 150 can be prevented from being discharged towards the user's area to be treated or the user's area, thereby improving the user experience.

[0059] In some embodiments of this application, the air inlet of the second fan 420 faces the second air inlet 140, and the first fan 410 is disposed on the side of the second fan 420 away from the second air inlet 140. The first fan 410 and the second fan 420 are stacked and isolated from each other to optimize the space occupied by the first fan 410 and the second fan 420, making the heat dissipation component 400 more compact, reducing the space occupied by the heat dissipation component 400 inside the housing 100, and improving the space utilization rate inside the housing 100.

[0060] In some embodiments of this application, both the first fan 410 and the second fan 420 are centrifugal fans with an axial air intake and radial air exhaust structure. The port of the first channel 110 facing away from the first air inlet 130 and the port of the second channel 120 facing away from the second air inlet 140 are arranged side by side. The use of centrifugal fans for the first fan 410 and the second fan 420 allows them to be stacked vertically without affecting their air intake and exhaust. While ensuring air intake and exhaust, this makes the heat dissipation assembly 400 more compact, reducing the space occupied by the heat dissipation assembly 400 inside the housing 100 and improving the space utilization rate inside the housing 100.

[0061] In some embodiments of this application, see Figure 4 and Figure 5 As shown, the radiator 430 is located on the side of the second fan 420 near the second air inlet 140 and is spaced apart from the second fan 420. The radiator 430 has a ventilation channel 4310 for external airflow to pass through. The ventilation channel 4310 corresponds to the second air inlet 140, so that external airflow can flow into the second fan 420 through the ventilation channel 4310. Since the radiator 430 is connected to the hot surface of the cooling fin 320, the radiator 430 can absorb the heat from the hot surface of the cooling fin 320. When external airflow flows through the ventilation channel 4310, the external airflow can carry away the heat from the radiator 430, thereby reducing the temperature of the cooling fin 320.

[0062] In some embodiments of this application, the heat sink 430 includes multiple heat dissipation fins 431, which are arranged at intervals within the second channel 120. The heat dissipation fins 431 are disposed within the second channel 120 and extend in the direction of external airflow. A ventilation channel 4310 is formed between adjacent heat dissipation fins 431 for external airflow. The heat dissipation fins 431 are connected to the cooling plate 320, allowing the cooling plate 320 to transfer heat to the heat dissipation fins 431. The multiple heat dissipation fins 431 allow for wider heat dissipation from the hot surface of the cooling plate 320, resulting in more dispersed heat distribution and lower temperature for each heat dissipation fin 431. This allows the external airflow to more effectively reduce the temperature of the heat dissipation fins 431, thereby effectively reducing the temperature of the cooling plate 320.

[0063] In some embodiments of this application, the beauty device 10 further includes a heat pipe 700. One end of the heat pipe 700 is in contact with the hot surface of the cooling chip 320 to remove heat from the hot surface. The other end of the heat pipe 700 is connected to the heat dissipation fin 431 to ultimately transfer the heat from the hot surface to the heat dissipation fin 431. That is, the heat dissipation fin 431 is connected to the hot surface of the cooling chip 320 through the heat pipe 700.

[0064] It is understandable that when the external airflow flows in the second channel 120, it gradually carries away the heat from the heat dissipation fins 431 and the heat pipe 700, thereby gradually reducing the heat of the heat pipe 700 and thus reducing the heat of the hot surface of the cooling chip 320.

[0065] In some embodiments of this application, the heat pipe 700 may also be made of a material with good thermal conductivity, such as copper. A heat-conducting sheet 800 is further provided between the hot surface of the cooling chip 320 and the heat pipe 700. One side of the heat-conducting sheet 800 is in contact with the hot surface, and the other side is in contact with the heat pipe 700. The heat-conducting sheet 800 may be made of a material with good thermal conductivity, such as copper. One side of the heat-conducting sheet 800 is in contact with the hot surface of the cooling chip 320 to dissipate heat from the hot surface of the cooling chip 320; that is, heat from the hot surface of the cooling chip 320 is transferred to the heat-conducting sheet 800.

[0066] Among them, see Figure 7 As shown, the heat pipe 700 includes a first heat-conducting part 710 that is attached to the heat-conducting plate 800 and a second heat-conducting part 720 that penetrates the heat dissipation fins 431. The first heat-conducting part 710 transfers heat from the heat-conducting plate 800 to the second heat-conducting part 720, and the second heat-conducting part 720 releases heat onto the heat dissipation fins 431.

[0067] In some embodiments of this application, please refer to... Figure 7 As shown, the heat pipe 700 adopts a U-shaped tube and has two oppositely arranged second heat-conducting parts 720. Both second heat-conducting parts 720 are connected to the heat dissipation fins 431 so that more heat can be transferred to the heat dissipation fins 431. This allows for more effective transfer of heat from the heat pipe 700 to the heat dissipation fins 431, thereby rapidly cooling the hot surface of the cooling chip 320.

[0068] In other words, the heat on the hot surface of the cooling chip 320 is discharged through the heat-conducting plate 800, the first heat-conducting part 710 and the second heat-conducting part 720 and the heat dissipation fins 431. Finally, the external airflow in the second channel 120 is used to cool the heat dissipation fins 431, the first heat-conducting part 710 and the second heat-conducting part 720 to reduce the temperature on the heat-conducting pipe 700, thereby reducing the temperature of the hot surface of the cooling chip 320, so as to reduce the temperature inside the shell 100, reduce the temperature of the beauty device 10 body, and improve the user experience.

[0069] In other embodiments of this application, see Figure 5 and Figure 7 As shown, the end of the heat pipe 700 furthest from the cooling fin 320 is connected to multiple heat dissipation fins 431 to transfer heat from the heat pipe 700 to the heat dissipation fins 431. When external airflow passes through the ventilation channel 4310 between adjacent heat dissipation fins 431, it gradually carries away the heat from the heat dissipation fins 431, reducing their temperature and consequently lowering the temperature of the heat pipe 700. The multiple heat dissipation fins 431 effectively remove heat from the heat pipe 700, improving heat dissipation efficiency.

[0070] Please refer to some embodiments of this application. Figure 7 As shown, each of the heat dissipation fins 431 has a mounting port (not shown in the figure) facing the second air inlet 140 on one side. The mounting ports of multiple heat dissipation fins 431 form a mounting position (not shown in the figure), and the heat pipe 700 is embedded in the mounting position. External airflow can not only remove heat from the heat dissipation fins 431, but also remove heat from the heat pipe 700, further improving the heat dissipation effect of the heat pipe 700, and thus improving the heat dissipation effect of the cooling chip 320.

[0071] In some embodiments of this application, a detection port (not shown in the figures) is also provided on the housing 100. The detection port and the light-emitting port are both arranged on the same side of the housing 100, and are adjacent to each other but spaced apart. The detection port can be used to allow detection light emitted by the skin color detection module 900 (described below) to pass through, so that the detection light can reach the user's skin. The detection port can also be used to reflect the detection light reflected back from the user's skin back to the skin color detection module 900, so that the skin color detection module 900 can acquire the user's skin color information.

[0072] Please refer to some embodiments of this application. Figure 3 and Figure 7 As shown, the beauty device 10 also includes a skin tone detection module 900 disposed inside the housing 100. It is adjacent to and located on one side of the light-transmitting cooling compress 310. The skin tone detection module 900 emits detection light for detecting skin tone. The detection light reaches the user's skin through the aforementioned detection port, is reflected upon contact with the user's skin, and is reflected back to the skin tone detection module 900 through the detection port. The skin tone detection module 900 can acquire the user's skin tone information.

[0073] Please refer to some embodiments of this application. Figure 2As shown, the beauty device 10 also includes a drive circuit board 1000 disposed inside the housing 100. This drive circuit board 1000 is electrically connected to the light-emitting element 200 and the skin tone detection module 900. The drive circuit board 1000 can receive skin tone information of the user's skin acquired by the skin tone detection module 900, and control the light intensity of the beauty light emitted by the light-emitting element 200 according to the skin tone information. This allows for automatic adjustment of the light intensity of the beauty light according to different skin tones, avoiding skin damage and improving the safety performance of the beauty device 10.

[0074] Please refer to some embodiments of this application. Figure 4 and Figure 7 As shown, the light-emitting component 200, the cooling component 300, the skin color detection module 900, and the heat dissipation component 400 can be an integrated structure, that is, the light-emitting component 200, the cooling component 300, the skin color detection module 900, and the heat dissipation component 400 are integrated into one unit.

[0075] For example, please continue to see Figure 4 and Figure 7 As shown, the beauty device 10 includes an integrated housing 1100, within which a first channel 110 and a second channel 120 are provided. The first channel 110 houses a light-emitting element 200, a reflector cup 500, and a first fan 410, while the second channel 120 houses a second fan 420. A heat pipe 700 and heat dissipation fins 431 are integrated on the outside of the integrated housing 1100. The first fan 410 and the second fan 420 are stacked vertically within the integrated housing 1100, and both have a bottom or top air intake and side air exhaust structure. A cooling assembly 300 and a skin tone detection module 900 are integrated on the outer top of the integrated housing 1100 and fixed to it by a bracket. The integrated housing 1100 has a buckle, and the housing 100 has a latch; the integrated housing 1100 is detachably connected to the housing 100 via the buckle and the latch.

[0076] It is worth mentioning that the integrated housing 1100 can also be connected to the housing 100 in other ways, such as by screws or adhesive.

[0077] It is understandable that by encapsulating the first fan 410, the second fan 420, the first channel 110, and the second channel 120 within the integrated housing 1100, a single module is formed, maintaining a stable internal structure. This prevents air leakage in the first channel 110 and / or the second channel 120 due to assembly process issues, thus avoiding problems with internal heat dissipation airflow.

[0078] Please refer to some embodiments of this application. Figure 2As shown, the beauty device 10 also includes an energy storage capacitor 1200 for storage and output. The energy storage capacitor 1200 is disposed inside the housing 100 and electrically connected to the light-emitting element 200, which enables the light-emitting element 200 to emit light for beauty purposes.

[0079] It should be noted that the beauty device 10 also includes a voltage converter (not shown in the figure) disposed within the housing 100. The voltage converter can cooperate with the energy storage capacitor 1200 to enable the light-emitting element 200 to achieve a flashing mode, thereby improving the beauty effect of the beauty device 10.

[0080] In addition, please see Figure 2 As shown, the bottom of the housing 100 is provided with a charging port (not shown in the figure), which can be used with an external charging cable to charge the energy storage capacitor 1200.

[0081] In some embodiments of this application, the beauty device 10 also includes a display screen 1300. The display screen 1300 is electrically connected to the drive circuit board 1000 and can receive electrical signals from the drive circuit board 1000 to display the electrical signals on the display screen 1300, thereby reflecting the functional mode of the beauty device 10 in a timely manner.

[0082] Please refer to some embodiments of this application. Figure 2 As shown, the beauty device 10 also includes multiple buttons 1400. When a button 1400 is pressed, the conductive contacts on the drive circuit board 1000 are turned on, and the drive circuit board 1000 outputs an electrical signal to control the light-emitting state of the light-emitting element 200, thereby regulating the working mode of the light-emitting element 200. For example: an on button (turns on the light-emitting element 200), a continuous irradiation button, a screen flash button, and brightness increase or decrease buttons, etc.
