Description

Technical Field

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

[0002] Currently, beauty devices on the market often suffer from excessive heat generated by the light source, which can easily cause the device to overheat. When users hold the device during use, this can lead to reduced lifespan of internal components due to high temperatures. Furthermore, continuous contact with the heated device can cause users to experience excessive hand temperature, sweating, and other unpleasant sensations.

[0003] To prevent the user's hand from getting hot, some beauty devices have a handle-like structure on the outer shell; others have large air vents on the front or back shell to improve heat dissipation.

[0004] However, such beauty devices have problems such as large size, inconvenience in carrying and storing, and air outlets blowing air towards the human body, which reduces the user experience. Utility Model Content

One end of the air outlet channel is connected to the outlet of the heat dissipation component, and the other end is connected to the air outlet. The light-emitting element is disposed in the first heat dissipation channel, and the heat dissipation component is disposed in the second heat dissipation channel. Under the action of the heat dissipation component, external air can enter the first heat dissipation channel from the first air inlet, and the external air can also enter the second heat dissipation channel through the second air inlet and the ventilation channel, so as to carry the heat emitted by the light-emitting element and the heat on the heat dissipation component into the heat dissipation component. The heat dissipation component can release the external air after absorbing heat into the air outlet channel and exhaust it through the air outlet.

[0007] In one exemplary embodiment of this application, the second air inlet and the light outlet are respectively located on opposite sides of the housing; the housing includes a grip portion, and the air outlet is located on the opposite side of the grip portion.

[0008] In one exemplary embodiment of this application, the outlet of the first heat dissipation channel and the outlet of the second heat dissipation channel are respectively located on opposite sides of the heat dissipation component.

[0009] In one exemplary embodiment of this application, the cold compress component includes: a cold compress member, including a conductive surface and a contact surface, the contact surface being in contact with the user's area to be treated; and a cooling member, the two opposite sides of the cooling member being a cold surface and a hot surface, the cold surface being in contact with the conductive surface to cool the conductive surface, the hot surface being in contact with the heat dissipation member, the heat dissipation member being able to remove heat from the hot surface.

[0010] In an exemplary embodiment of this application, the heat dissipation component includes: a radiator, one end of which is in contact with the hot surface to remove heat from the hot surface; and heat dissipation fins disposed within the second heat dissipation channel, one end of which is connected to the heat dissipation component to remove heat from the radiator, and the other end of which extends in the direction of the external airflow, wherein the external airflow can carry the heat from the heat dissipation fins into the heat dissipation component, so that the heat from the heat dissipation fins can be released to the outside through the air outlet.

[0011] In one exemplary embodiment of this application, multiple heat dissipation fins are spaced apart from each other within the second heat dissipation channel, and the external wind can carry away the heat from the multiple heat dissipation fins.

[0012] In one exemplary embodiment of this application, the heat sink includes: a heat sink fin, one side of which is attached to the hot surface to remove heat from the hot surface; and a heat sink pipe, one end of which is attached to the other side of the heat sink fin to remove heat from the heat sink fin, and the other end of which is connected to the heat sink fins to transfer heat from the heat sink pipe to the heat sink fins.

[0013] In one exemplary embodiment of this application, the beauty device further includes a main control board disposed within the mounting cavity, the main control board being electrically connected to the light-emitting element; wherein at least a portion of the main control board is disposed within the ventilation channel.

[0015] In one exemplary embodiment of this application, the beauty device further includes an energy storage capacitor for storing and outputting light. The energy storage capacitor is disposed in the mounting cavity and electrically connected to the light-emitting element so that the light-emitting element emits light for beauty purposes.

[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 device. The housing has a light outlet, a first air inlet, a second air inlet, and an air outlet located on different sides, with the light outlet located on the side of the housing facing the user's area to be treated. The heat dissipation device includes a first heat dissipation channel, a second heat dissipation channel, an air outlet channel, and a heat sink. The first heat dissipation channel connects the first air inlet and the heat sink, and the second heat dissipation channel connects the second air inlet and the heat sink. Under the action of the heat sink, external air enters the first and second heat dissipation channels through the first and second air inlets, respectively, to remove heat from the light-emitting element located in the first heat dissipation channel and the heat dissipation component of the cooling assembly located in the second heat dissipation channel, thereby reducing the heat on the light-emitting element and the heat dissipation component. The heat-absorbing external air is transferred to the heat sink through the first and second heat dissipation channels, and the heat sink discharges the heated external air into the air outlet channel and releases the heated external air through the air outlet. By incorporating a first air inlet, a second air inlet, and a heat dissipation device, the heat from the light-emitting component and the cooling component can be effectively dissipated without increasing the size of the beauty device. This effectively prevents the internal temperature of the beauty device from overheating, thereby extending the lifespan of the internal components and improving the user experience. Furthermore, by designing the air outlet and light outlet on opposite sides of the casing, the hot air released from the air outlet will not be directed towards one side of the user during use, further enhancing the user experience.

[0046] See Figure 1 and Figure 2 As shown, this application provides a beauty device 10, which includes a housing 100 and a light-emitting element 200, a cold compress component 300 and a heat dissipation device 400 disposed within the housing 100.

[0047] With the help of the light-emitting element 200 and the cooling component 300, the beauty device 10 can not only care for the user's skin but also apply a cooling compress to the area to be treated, achieving dual benefits and enhancing the user experience. Furthermore, while the light-emitting element 200 and the cooling component 300 are working, the heat dissipation device 400 gradually dissipates the heat from these components, lowering the internal temperature of the casing 100. This prevents damage to the internal components of the beauty device 10 due to excessively high internal temperatures and also avoids the user's hands becoming too hot and sweaty from contact with the heated device, thus improving the user experience.

[0048] In some embodiments of this application, see Figures 3 to 5 As shown, the shell 100 can be elliptical or other shapes, such as square or circular structures.

[0049] It should be noted that the housing 100 can define the overall shape of the beauty device 10.

[0050] In some embodiments of this application, see Figure 1 and Figure 2 As shown, the housing 100 has an internal cavity structure, that is: the housing 100 includes a mounting cavity (not shown in the figure), and the light-emitting element 200, the cooling assembly 300 and the heat dissipation device 400 are all located in the mounting cavity.

[0051] In some embodiments of this application, see Figure 1 and Figure 6 As shown, a light outlet 110 is provided on the housing 100. The light outlet 110 allows the cosmetic light emitted by the light-emitting element 200 to pass through, so as to perform cosmetic treatment on the user's area to be treated.

[0052] In some embodiments of this application, see Figure 3 and Figure 4As shown, the housing 100 is also provided with a first air inlet 120, a second air inlet 130, and an air outlet 140. Under the action of the heat dissipation device 400, external cooling air can enter the mounting cavity through the first air inlet 120 and the second air inlet 130. The external cooling air cools the light-emitting element 200 and the cooling assembly 300 to reduce the heat generated by the light-emitting element 200 and the cooling assembly 300. After absorbing the heat, the external cooling air is discharged from the air outlet 140 through the heat dissipation device 400 to reduce the temperature inside the mounting cavity, thereby reducing the temperature of the beauty device 10 body.

[0053] It should be noted that in some embodiments of this application, the light outlet 110 faces the side of the user's area to be treated, while the first air inlet 120, the second air inlet 130, and the air outlet 140 are respectively located on different sides of the housing 100 from the light outlet 110. That is, the first air inlet 120, the second air inlet 130, and the air outlet 140 do not face the side of the user's area to be treated, which can prevent the hot air released from the air outlet 140 from being discharged towards the user's area to be treated and the user area, thereby improving the user experience.

[0054] In addition, see Figure 1 As shown, a ventilation channel 150 is provided inside the installation cavity. One end of the ventilation channel 150 can be connected to the second air inlet 130 so as to introduce external cooling air into the ventilation channel 150.

[0055] In some embodiments of this application, see Figure 1 and Figure 2 As shown, the light-emitting element 200 can be disposed in the mounting cavity and fixed relative to the housing 100 so that the light-emitting element 200 can slide and fall off, ensuring the stability of the light-emitting element 200 and thus ensuring the beauty effect of the beauty device 10.

[0056] The light-emitting element 200 can correspond to the light-emitting port 110. The light-emitting element 200 can emit light for beauty purposes. The beauty light can pass through the light-emitting port 110 and be directed at the area of ​​the user to be treated, so as to achieve a beauty effect on the user's skin.

[0057] In some embodiments of this application, see Figure 1 As shown, the cooling compress assembly 300 includes a cooling compress component 310. The cooling compress component 310 is located at the light outlet 110 and is spaced apart from the light-emitting element 200 in the light-emitting direction of the light-emitting element 200. The cooling compress component 310 has a contact surface for contacting the user's skin, located at the light outlet 110 for easy contact. The cooling compress component 310 can continuously cool the user's skin during the operation of the light-emitting element 200, reducing burning sensation and improving the user experience.

[0058] In some embodiments of this application, please refer to... Figure 1 As shown, the cooling compress assembly 300 also includes a heat dissipation component 320. The heat dissipation component 320 is connected to the cooling compress assembly 310 and can remove heat from the cooling compress assembly 310, thereby reducing the temperature of the cooling compress assembly 310 and keeping the cooling compress assembly 310 at a low temperature to ensure the cooling effect.

[0059] In some embodiments of this application, the heat dissipation device 400 of the beauty device 10 is disposed in the mounting cavity. The heat dissipation device 400 can carry the heat generated by the light-emitting element 200 and the heat dissipation component 320 out of the mounting cavity, ensuring the temperature inside the mounting cavity is stable, thereby ensuring the integrity of the components inside the mounting cavity, so as to ensure the beauty effect of the beauty device 10.

[0060] In some embodiments of this application, see Figure 1 As shown, the heat dissipation device 400 includes a heat dissipation body (not shown in the figure) and a heat dissipation component 410 installed and fixed inside the heat dissipation body. The heat dissipation body is provided with a first heat dissipation channel 420, a second heat dissipation channel 430 and an air outlet channel 440, all of which are connected to the heat dissipation component 410.

[0061] Among them, see Figure 1 and Figure 2 As shown, one end of the first heat dissipation channel 420 can be connected to the first air inlet 120, and the other end can be connected to the heat sink 410. One end of the second heat dissipation channel 430 can be connected to the side of the ventilation channel 150 away from the second air inlet 130, that is, the second heat dissipation channel 430 is connected to the second air inlet 130 through the ventilation channel 150, and the cooling air flowing in from the second air inlet 130 flows into the second heat dissipation channel 430 through the ventilation channel 150. The other end of the second heat dissipation channel 430 is connected to the heat sink 410. One end of the air outlet channel 440 is connected to the exhaust port of the heat sink 410, and the other end is connected to the air outlet 140.

[0062] It should be noted that the light-emitting element 200 is located in the first heat dissipation channel 420, and the heat dissipation component 320 is located in the second heat dissipation channel 430.

[0063] See Figure 1 and Figure 2As indicated by the middle arrow, under the action of the heat sink 410, the interior of the heat sink body is under low pressure, while the outside is under high pressure. According to the pressure relationship, the external cooling air can enter the first heat dissipation channel 420 through the first air inlet 120. The cooling air gradually carries away the heat generated by the light-emitting element 200, and the hot air that has absorbed the heat is then discharged into the heat sink 410 through the first heat dissipation channel 420. In addition, the external cooling air can also enter the second heat dissipation channel 430 through the second air inlet 130 and the ventilation channel 150. The cooling air gradually carries away the heat on the heat sink 320, and the hot air that has absorbed the heat is then discharged into the heat sink 410 through the second heat dissipation channel 430.

[0064] Two streams of hot air converge in the heat sink 410 and, under the action of the heat sink 410, are discharged through the air outlet 140 via the air outlet 440. This discharges the hot air that has absorbed heat from the light-emitting element 200 and the heat sink 320, thereby reducing the temperature of the light-emitting element 200 and the heat sink 320, lowering the internal temperature of the mounting cavity, and protecting the electronic components inside the mounting cavity. Furthermore, lowering the internal temperature of the mounting cavity also prevents users from experiencing excessively high hand temperatures or sweating due to continuous contact with the hot body, improving the user experience.

[0065] The beauty device 10 of this application can cool down the light-emitting element 200 and the heat dissipation component 320 in the cooling assembly 300 through a first heat dissipation channel 420, a second heat dissipation channel 430, a heat dissipation component 410, a first air inlet 120, a second air inlet 130, an air outlet channel 440, and an air outlet 140. This achieves the goal of reducing the body temperature of the beauty device 10 without increasing its size, making it easy to carry and store. Furthermore, by lowering the temperature of the light-emitting element 200 and the heat dissipation component 320, the temperature inside the mounting cavity can be reduced, ensuring that the electronic components inside the mounting cavity operate at normal temperatures, thus guaranteeing that the beauty device 10 is in a normal working environment. Moreover, the reduced temperature inside the mounting cavity also prevents the device from overheating when held, improving the user experience.

[0066] In this application, the air outlet 140 and the light outlet 110 are located on different sides of the housing 100 so that the hot air released by the air outlet 140 is directed away from the user's area to be treated and away from the user area, thereby improving the user experience.

[0067] In some embodiments of this application, see Figure 5 As shown, the housing 100 includes a top wall (not shown) and a bottom wall (not shown) disposed opposite to each other. The aforementioned light outlet 110 is provided on the top wall, and the light outlet 110 and the second air inlet 130 are disposed opposite to each other. That is, the second air inlet 130 is located on the bottom wall of the housing 100.

[0068] In some embodiments of this application, the housing 100 also includes a grip (not shown in the figures). It should be noted that when the user holds the beauty device 10, the side wall covering one side of the housing 100 serves as the grip. The user holds the grip to perform beauty treatments on the area to be treated. The air outlet 140 is located on the opposite side of the grip, meaning the air outlet 140 directs airflow away from the skin's application area and away from the user's area, thereby improving the user experience.

[0069] In some embodiments of this application, the housing 100 further includes a sidewall (not shown in the figure), one end of which is arranged around the outer edge of the top wall, and the other end of which is arranged around the outer edge of the bottom wall. The sidewall may include a front side (not shown in the figure), a back side (not shown in the figure), a first side side (not shown in the figure), and a second side side (not shown in the figure). The front side is the side with control buttons, and the front side is arranged opposite to the back side. The front side is connected to the back side through the first side side and the second side side, and the first side side is arranged opposite to the second side side.

[0070] When the user holds the beauty device 10, it can cover the first side, which is the grip part. The air outlet 140 is located on the second side to prevent the air outlet 140 from blowing air towards the skin area or the user area, thus improving the user experience.

[0071] It should be noted that the first air inlet 120 can be located on the first side, or on the front or back of the side wall, as long as the first air inlet 120 is correspondingly set with the light-emitting element 200 and does not obstruct the air intake of the first air inlet 120 when the user holds it.

[0072] For example, the first air inlet 120 is located on the back side wall of the housing 100 to facilitate air intake through the first air inlet 120.

[0073] Figure 7 This illustration shows a schematic diagram of the connection structure between the heat dissipation device, the light-emitting element, and the cooling assembly provided in an embodiment of this application. Figure 8 The diagram shows a cross-sectional view of the heat dissipation device provided in an embodiment of this application. Figure 9 A cross-sectional structural schematic diagram of the heat dissipation device, light-emitting element, and cooling assembly provided in the embodiments of this application is shown. Figure 10 This illustration shows a cross-sectional perspective view of the heat dissipation device, light-emitting element, and cooling assembly provided in an embodiment of this application. Figure 11 A three-dimensional structural diagram of the heat dissipation device, light-emitting element, and cooling assembly provided in the embodiments of this application is shown.

[0074] In some embodiments of this application, the heat sink 410 may be a fan. See also Figure 9As shown, the outlets of the first heat dissipation channel 420 and the second heat dissipation channel 430 are respectively located on opposite sides of the heat sink 410, meaning air enters from opposite sides of the fan. The first heat dissipation channel 420 and the second heat dissipation channel 430 are independent of each other and do not interfere with each other. That is, hot air from the first heat dissipation channel 420 will not flow into the heat dissipation component 320, nor will hot air from the second heat dissipation channel 430 flow into the light-emitting component 200, thus ensuring heat dissipation effect and improving heat dissipation efficiency.

[0075] In some embodiments of this application, see Figure 2 and Figure 8 As shown, the air outlet channel 440 is located on one side of the heat sink 410. No electronic components are provided on one side of the air outlet channel 440, which provides better protection for the electronic components and ensures the normal operation of the beauty device 10.

[0076] It is worth mentioning that, see Figure 2 As shown, the heat sink can adopt a volute-shaped structure to improve air intake and exhaust efficiency. The opposite sides of the volute-shaped heat sink are respectively supplied with air intake for the first heat dissipation channel 420 and the second heat dissipation channel 430.

[0077] In addition, the outlet of the first heat dissipation channel 420 can be a plurality of spaced openings, through which hot air in the first heat dissipation channel 420 flows into the heat sink 410.

[0078] In some embodiments of this application, see Figure 9 and Figure 10 As shown, the light-emitting component 200 includes a light source 210, a reflector 220, and a filter 230. The filter 230 is disposed in the light-emitting direction of the light source 210. The reflector 220 covers the light source 210 and is connected to the filter 230, so that the beauty light generated by the light source 210 can completely pass through the filter 230 and be directed to the light outlet 110, thereby improving the light utilization rate and ensuring the beauty effect.

[0079] It is understandable that the filter 230 can filter the light emitted by the light source 210 to obtain the corresponding beauty light, thereby obtaining the corresponding beauty effect.

[0080] In addition, the light source 210 can be any light source that can emit light directly or through the filter 230, such as LED, xenon lamp, halogen lamp, thermal radiation lamp, tungsten filament lamp, etc., for skin treatments such as beauty hair removal.

[0081] In some embodiments of this application, the light source 210 and the reflector 220 are placed in the first heat dissipation channel 420. The cooling air entering from the first air inlet 120 can gradually remove the heat from the light source 210 and the reflector 220, reduce the heat of the light source 210 and the reflector 220, ensure the temperature environment inside the mounting cavity, and thus ensure that the electronic components inside the mounting cavity work in a normal environment, and ensure the beauty effect of the beauty device 10.

[0082] In some embodiments of this application, the cold compress component 310 may include a cold compress component 311 and a cooling component 312. The cooling component 312 can quickly cool down the cold compress component 311 so that the cold compress component 311 is in a low temperature state when it comes into contact with the user's skin, thus ensuring the cold compress effect.

[0083] Among them, the cooling component 311 can be made of materials with good light transmittance and good thermal conductivity, such as sapphire (Al2O3), quartz, or K9 glass.

[0084] It should be noted that, see Figure 9 and Figure 10 As shown, the cooling compress 311 is located on the side of the filter 230 away from the light source 210. By using the cooling compress 311 with good light transmittance and thermal conductivity, it is possible to avoid blocking the light emitted by the light source 210 and ensure the amount of light emitted. It is also possible to ensure that the cooling component 312 can quickly cool down the cooling compress 311, thereby quickly cooling the skin surface, reducing heat transfer to the skin, and thus improving the user experience.

[0085] The cooling compress 311 has a contact surface (not shown in the figure) and a conductive surface (not shown in the figure). The contact surface contacts the area to be treated by the user, and the conductive surface is located on one side of the cooling compress 311, that is, the conductive surface is located on the side wall of the cooling compress 311.

[0086] In some embodiments of this application, see Figure 9 and Figure 10 As shown, the beauty device 10 also includes a fixing frame 500, through which the cooling compress 311 is fixed in the mounting cavity. The fixing frame 500 can be an opaque structure so that the beauty light emitted by the light-emitting element 200 can completely pass through the cooling compress 311 and then be emitted from the light outlet 110, ensuring the light emission rate and thus ensuring the beauty effect.

[0087] It should be noted that the mounting bracket 500 has a window on one side that exposes the conductive surface of the cooling patch 311.

[0088] In some embodiments of this application, see Figure 9 and Figure 10As shown, the cooling component 310 may further include a cooling element 312. The cooling element 312 may be a semiconductor cooling chip, and the cooling element 312 may form a cold surface (not shown) for absorbing heat and a hot surface (not shown) for releasing heat when energized.

[0089] The cold side is in contact with the conductive surface through the window, gradually carrying away the heat from the conductive surface and keeping the cooling compress 311 at a low temperature, thus ensuring the cooling effect of the cooling compress 311. The hot side is in contact with the heat dissipation component 320, which gradually transfers heat away from the hot side, reducing the temperature of the hot side of the cooling component 312. Then, the heat dissipation device 400 gradually reduces the heat on the heat dissipation component 320, that is, it gradually reduces the temperature of the hot side of the cooling component 312.

[0090] In other words, the heat generated by the light-emitting element 200 is gradually reduced through the first air inlet 120, the first heat dissipation channel 420, the heat sink 410, the air outlet channel 440, and the air outlet 140. The heat of the cooling element 312 in the cooling assembly 300 is gradually reduced through the second air inlet 130, the ventilation channel 150, the second heat dissipation channel 430, the heat sink 410, the air outlet channel 440, and the air outlet 140. By gradually reducing the temperature inside the mounting cavity through two independent heat dissipation channels, the electronic components inside the mounting cavity are kept at a normal operating temperature, thereby ensuring the working environment of the beauty device 10 and guaranteeing its beauty effect.

[0091] In some embodiments of the application, participants Figure 1 , Figure 7 and Figure 8 As shown, the heat dissipation component 320 includes a heat sink 321 and heat dissipation fins 322. One end of the heat sink 321 is in contact with the hot surface to remove heat from the hot surface, and the other end of the heat sink 321 is connected to the heat dissipation fins 322 to ultimately transfer the heat from the hot surface to the heat dissipation fins 322. The heat dissipation fins 322 are disposed within the second heat dissipation channel 430 and extend in the direction of the external cooling airflow.

[0092] It is understandable that when the external cooling air flows in the second heat dissipation channel 430, it gradually carries away the heat on the heat dissipation fins 322, thereby gradually reducing the heat of the heat sink 321, and thus reducing the heat on the hot surface of the cooling component 312.

[0093] In some embodiments of this application, see Figure 7 and Figure 8As shown, the heat dissipation component 320 includes multiple heat dissipation fins 322, which are arranged at intervals within the second heat dissipation channel 430. Adjacent heat dissipation fins 322 form channels through which external cooling air flows. As the external cooling air flows through these channels, it gradually carries away heat from the heat dissipation fins 322, reducing their temperature and consequently lowering the temperature of the radiator 321 and the hot surface of the cooling component 312. The multiple heat dissipation fins 322 effectively dissipate heat from the radiator 321 and the hot surface of the cooling component 312, improving heat dissipation efficiency.

[0094] In some embodiments of this application, see Figure 9 and Figure 11 As shown, the heat sink 321 includes a heat sink 3210. The heat sink 3210 can be made of a material with good thermal conductivity, such as copper. One side of the heat sink 3210 is in contact with the hot surface of the cooling component 312 to remove heat from the hot surface of the cooling component 312, that is, the heat from the hot surface of the cooling component 312 is transferred to the heat sink 3210.

[0095] In some embodiments of this application, see Figure 9 and Figure 10 As shown, the heat sink 321 also includes a heat pipe 3211. The heat pipe 3211 can also be made of a material with good thermal conductivity, such as copper. One end of the heat pipe 3211 is attached to the side of the heat sink 3210 away from the cooling component 312 to remove heat from the heat sink 3210. The other end of the heat pipe 3211 is connected to the heat dissipation fins 322 to transfer heat from the heat pipe 3211 to the heat dissipation fins 322.

[0096] In other words, the heat on the hot surface of the cooling component 312 is dissipated through the heat sink 3210, heat pipe 3211 and heat sink fin 322. Finally, the external cooling air in the second heat dissipation channel 430 is used to cool and reduce the temperature of the heat sink 321, thereby reducing the temperature of the hot surface of the cooling component 312, so as to reduce the temperature inside the installation cavity, reduce the temperature of the beauty device 10 body, and improve the user experience.

[0097] In some embodiments of this application, see Figure 2 As shown, the beauty device 10 also includes a main control board 600 disposed inside the mounting cavity. The main control board 600 is electrically connected to the light-emitting element 200 and can control the light-emitting element 200 to emit beauty light.

[0098] It should be noted that at least a portion of the main control board 600 is located within the ventilation channel 150. This means that external cooling air entering from the second air inlet 130 pre-cools the main control board 600 before flowing into the second heat dissipation channel 430 to cool the heat sink 322. By having external cooling air pre-pass through the main control board 600 and then through the heat sink 322, better protection can be provided for the electronic components on the main control board 600.

[0099] In some embodiments of this application, see Figure 1 As shown, the beauty device 10 also includes LEDs 700 and a circuit board 800 disposed within the mounting cavity. The LEDs 700 array is arranged on the circuit board 800, and the LEDs 700 can emit light towards the light outlet 110 under the control of the circuit board 800. The LEDs 700 and the circuit board 800 are disposed on one side of the cooling component 311 and above the cooling component 312 and the heat sink 3210, so that the light emitted by the LEDs 700 is not blocked, ensuring the light emission effect.

[0100] The LED700 and circuit board 800 can provide supplemental beauty light to the light-emitting element 200, or they can provide only lighting functions, or they can provide other functions.

[0101] In some embodiments of this application, see Figure 1 As shown, the beauty device 10 also includes an energy storage capacitor 900 for storage and output. The energy storage capacitor 900 is disposed in the mounting cavity and electrically connected to the light-emitting element 200, which enables the light-emitting element 200 to emit light for beauty purposes.

[0102] It should be noted that, see Figure 1 As shown, the beauty device 10 also includes a voltage converter 1000. The voltage converter 1000 can work in conjunction with the energy storage capacitor 900 to enable the light-emitting element 200 to achieve a flashing mode, thereby improving the beauty effect of the beauty device 10.

[0103] In some embodiments of this application, see Figure 1 As shown, the beauty device 10 also includes a skin tone recognition module 1100. The skin tone recognition module 1100 can adjust the brightness of the light-emitting element 200 according to the user's skin, thereby improving the beauty effect.

[0104] It is understandable that filters can be installed at the first air inlet 120, the second air inlet 130, and the air outlet 140 to prevent external impurities from entering the interior of the housing 100, ensuring that the interior of the housing 100 is clean and tidy, thereby ensuring the working condition of the beauty device 10.

[0105] The solution of this application achieves a low-pressure environment inside the heat sink body and a high-pressure environment outside the heat sink body under the action of the heat sink 410. According to the pressure relationship, the external cooling air can enter the first heat dissipation channel 420 and the second heat dissipation channel 430 through the first air inlet 120 and the second air inlet 130 respectively. The cooling air gradually carries away the heat from the light-emitting element 200 and the heat dissipation component 320. The hot air that has absorbed the heat is discharged into the heat sink 410 through the first heat dissipation channel 420 and the second heat dissipation channel 430 respectively.

[0106] Two streams of hot air are discharged to the air outlet 140 through the air outlet 440 under the action of the heat sink 410, thereby reducing the temperature of the light-emitting component 200 and the heat sink 320, reducing the temperature inside the mounting cavity, thus protecting the electronic components inside the mounting cavity, and also preventing users from continuously contacting the hot body, which could cause their hands to get too hot or sweaty, thus improving the user experience.
