DETAILED DESCRIPTION

[0039] Example 1

[0040] This embodiment provides a beauty instrument to solve the problems in the related art that existing beauty instruments have low light power, few wavelengths, low light intensity, and poor heat dissipation capabilities, making them unable to be used for a long time.

[0041] Please refer to Figures 2 to 4, a beauty instrument includes an optical path structure 300 and a heat dissipation structure 200. The optical path structure 300 includes a light-emitting component 310, a light-guiding component 320, and a reflective component 330. The light-emitting component 310 includes a halogen lamp. The light-guiding component 320 includes a light-transmitting crystal 321 and a filter 322. The filter 322 is arranged between the light-transmitting crystal 321 and the halogen lamp, and the light-transmitting crystal 321 and the filter 322 are integrally formed. The reflective component 330 is arranged on the outside of the light-emitting component 310. The reflective component 330 can reflect the light emitted by the light-emitting component 310 and allow the light to pass through the light-guiding component 320. The heat dissipation structure 200 includes a cooling component, which can cool and dissipate heat for the optical path structure 300.

[0042] Specifically, when using the beauty device of this embodiment, the light emitting component 310 emits light, that is, the halogen lamp emits light. After being reflected by the reflective component 330, the light is transmitted to the light guide component 320 and passes through the filter 322 and the light-transmitting crystal 321 in sequence. The filter 322 can filter the light emitted by the halogen lamp, isolating unnecessary stray light, and allowing light of a specific wavelength to pass through the light-transmitting crystal 321 and act on the user's skin to beautify the user's skin. When using this embodiment, the main heat source is the optical path structure 300, and the cooling component cools and dissipates the entire optical path structure 300, allowing this embodiment to be used for a long time, thereby quickly and efficiently solving the user's skin problems.

[0043] It should be noted that in the light guide assembly 320, the filter 322 and the light-transmitting crystal 321 are integrally formed, that is, the two are configured as a whole. In this way, when light passes through the light guide assembly 320 of this embodiment, the loss of light can be reduced, and the intensity of light irradiated on the user's skin can be increased. Specifically, the light emitted by a halogen lamp will suffer a loss of 5% to 7% each time it passes through a layer of mirror. The light path structure 300 in which the light-transmitting crystal 321 and the filter 322 are separately configured has a light loss of 10% to 14%. However, the overall configuration of this embodiment has a light loss of only 5% to 7%. As a result, the light emitted from the light guide assembly 320 in this embodiment has less loss and higher light intensity, making the beauty instrument of this embodiment more effective.

[0044] It is understandable that there are many types of halogen lamps. When using them, lamps of different wavelengths can be selected according to actual needs, as long as they can solve the skin problems. For example, a tungsten filament lamp can be selected as the light source. The tungsten filament lamp can emit a 900-1800mm near-infrared spectrum (peak 1300nm), which is platinum milk light, acting on the middle-deep dermis of the skin. When the surface layer of water in the skin is irradiated by platinum milk light, the distance between each water molecule increases, making the water in the skin "more fluid." Mitochondria are powered by an enzyme bound to their cell membrane. This enzyme can rotate like a molecular turbine, and being surrounded by more fluid water can make it easier to rotate, thereby producing more ATP (adenosine triphosphate). ATP, or adenosine triphosphate, is a coenzyme and the direct source of energy required for all life activities of tissue cells in the body. It can promote cell repair and regeneration in the body, enhance the biological activity of collagen fibers, redistribute the dermis, repair damaged skin, and make the skin an excellent reflector, thereby indirectly increasing the refractive index of the skin surface and playing a role in skin whitening and rejuvenation.

[0045] It should be noted that depending on the halogen lamp selected, the filter 322 also needs to be selected based on actual conditions. The filter 322 can absorb certain wavelengths of light. Due to its characteristics, the filter 322 can work in conjunction with the halogen lamp to filter and absorb unwanted clutter in the light emitted by the halogen lamp. This makes the light that passes through the filter 322 and illuminates the light-transmitting crystal 321 purer, thereby enhancing the halogen lamp's cosmetic effect on the skin.

[0046] In one embodiment, for example, as shown in Figures 7 to 9, the reflective assembly 330 includes a first reflector 331 and a second reflector 332. The first reflector 331 is disposed around the exterior of the light-emitting assembly 310, and a light outlet is provided on the first reflector 331. The second reflector 332 is disposed between the light outlet and the light guide assembly 320. The first reflector 331 and the second reflector 332 reflect and guide the light emitted by the halogen lamp, directing the light emitted by the light-emitting assembly 310 to the light guide assembly 320 and emitting from the light-transmitting crystal 321 on the light guide assembly 320, thereby increasing the energy density of the light passing through the light-transmitting crystal 321.

[0047] The reflective component 330 reflects and guides the light to the translucent component. On the one hand, the light can be concentrated, that is, most of the light is guided by the reflective component 330 and emitted from the light guide component 320. On the other hand, other components can be prevented from being exposed to light and heated up due to the exposure to light, thereby reducing the heat dissipation pressure of the cooling channel 400 and the cooling component. At the same time, other components are protected and the service life of other components is increased, that is, the overall service life and structural stability of this embodiment are increased.

[0048] In one embodiment, for example, as shown in Figures 7 to 9, the first reflector 331 and the second reflector 332 are sealed together, and a portion of the second reflector 332 away from the first reflector 331 abuts against the filter 322. Furthermore, the second reflector 332 and the filter 322 are sealed together. Thus, the path between the light-emitting assembly 310 and the light-guiding assembly 320 is completely enclosed by the first reflector 331 and the second reflector 332, preventing light from leaking from the connection between the first reflector 331 and the second reflector 332 and the connection between the second reflector 332 and the light-guiding assembly 320. This further improves the light-concentrating capability of the reflector assembly 330, increases the intensity of the light emitted from the light-guiding assembly 320, and prevents other components outside the reflector assembly 330 from being exposed to light and causing heat or aging.

[0049] In one embodiment, for example, as shown in Figures 7 to 9, the first reflector 331 is configured in a semi-cylindrical shape, and the light-emitting assembly 310 is disposed within the first reflector 331, coinciding with the axis of the first reflector 331. By controlling the coaxiality between the halogen lamp and the first reflector 331, the coaxiality tolerance between the two is controlled within ±0.05 mm. In this way, the reflection trajectory of the light emitted by the halogen lamp can be precisely controlled, so that the light emitted by the halogen lamp can be repeatedly reflected to the light-transmitting crystal 321 under the action of the first reflector 331 and the second reflector 332, ensuring that the optical efficiency of the optical path structure 300 of this embodiment can reach 95%, and improving the energy density of the light output from the light-transmitting crystal 321.

[0050] Typically, the skin care efficacy of a home beauty device is primarily determined by the energy density of the light emitted by the device. Within a safe range, the higher the energy density, the better the effect. Energy density is affected by both energy and spot size: the greater the energy, the greater the energy density, and the smaller the spot size, the greater the energy density. Therefore, varying the energy density involves changing the energy intensity and the spot size. In this embodiment, the area of ​​the light guide assembly 320 remains fixed, and the reflective assembly 330 reflects and guides the light, allowing as much light as possible to be emitted from the light guide assembly 320. This effectively increases the energy density of the light, thereby enhancing the cosmetic effect of this embodiment.

[0051] It is understood that a reflective coating is provided inside the first reflector 331 and the second reflector 332. The reflective coating improves the light reflectivity of the inner walls of the first reflector 331 and the second reflector 332, preventing light from directly passing through the inner walls and irradiating other structures outside the reflective assembly 330, thereby preventing other structures from heating and protecting them. The reflective coating can be flexibly selected from different materials according to different light sources. For example, when using a tungsten filament lamp that can emit a near-infrared spectrum of 900-1800mm, selecting an aluminum-based silver-plated reflective film as the reflective coating can improve the optical efficiency of each light reflection on the reflective surface and reduce heat generation.

[0052] In one embodiment, as shown in Figures 3, 4, and 6, the cooling assembly includes a TEC cooling sheet 210, which abuts against the light guide assembly 320. The TEC cooling sheet 210 is capable of cooling and dissipating heat from the light guide assembly 320. The TEC cooling sheet 210 ensures that the temperature of the light guide assembly 320 remains at an appropriate level during use, providing a comfortable user experience. This addresses the safety hazard of burns caused by prolonged use of beauty devices in related technologies, and improves the comfort and safety of this embodiment.

[0053] In one embodiment, as shown in Figures 3, 4, and 6, the cooling assembly includes a TEC heat sink 220 and an optical path structure heat sink 230. The TEC heat sink 220 is capable of dissipating heat from the TEC cooling plate 210, while the optical path structure heat sink 230 is capable of dissipating heat from the optical path structure 300. The TEC heat sink 220 dissipates heat from the TEC cooling plate 210, ensuring that the TEC cooling plate 210 can dissipate heat from the light guide assembly 320, thereby ensuring that the temperature of the light guide assembly 320 remains appropriate. The optical path structure heat sink 230 dissipates heat from the optical path structure 300, ensuring that the overall internal temperature of this embodiment is appropriate.

[0054] It should be noted that the cooling capacity of the TEC cooling plate 210 is affected by the applied voltage. Specifically, the higher the voltage supplied to the TEC cooling plate 210, the greater its cooling capacity. Furthermore, in this embodiment, a control unit can be provided to control the voltage applied to the TEC cooling plate 210. When the temperature of the light guide assembly 320 is high, the voltage is increased to improve the cooling capacity of the TEC cooling plate 210. Conversely, the voltage is reduced. By controlling the TEC cooling plate 210, the light guide assembly 320 can be consistently maintained at an appropriate temperature during use, further enhancing the user experience of this embodiment.

[0055] In one embodiment, for example, as shown in Figures 3, 4, and 6, the TEC heat dissipation portion 220 includes a heat pipe 222 heat dissipation module, and the TEC refrigeration plate 210 includes a cooling end and a heating end. The cooling end is attached to the light guide component 320, and the heat pipe 222 heat dissipation module can dissipate heat from the heating end. The TEC refrigeration plate 210, that is, a semiconductor refrigeration plate (Thermo-Electric Cooler), also known as a Peltier element, is a solid-state thermoelectric refrigeration device that uses the Peltier effect to achieve cooling or heating functions. This effect is a thermoelectric phenomenon, that is, when an electric current passes through a junction composed of two different types of semiconductor materials (usually P-type and N-type semiconductors), it absorbs heat in one direction and releases heat in the other direction, thereby achieving heat transfer. Therefore, the TEC refrigeration plate 210 has a cooling end and a heating end. The cooling end is attached to the light guide assembly 320. When light passes through the light guide assembly 320, the light guide assembly 320 generates heat. The cooling end continuously absorbs the heat from the light guide assembly 320, cooling and dissipating it, keeping the light guide assembly 320 at a suitable temperature and improving the user experience of this embodiment. The heat pipe 222 continuously dissipates heat from the heating end of the TEC cooling plate 210, preventing excessive heat accumulation at the heating end and causing the temperature in the cooling channel 400 to rise.

[0056] In one exemplary embodiment, as shown in FIG5 , the heat pipe 222 includes a condenser element 221 and a heat pipe 222. The heat pipe 222 sequentially passes through the condenser element 221 and the TEC fin 210, forming a circulation loop. A working fluid flows through the heat pipe 222. When the working fluid in the heat pipe 222 flows near the TEC fin 210, due to the close proximity of the heat pipe 222 to the heating end of the TEC fin 210, the working fluid in the heat pipe 222 absorbs heat from the heating end, cooling and dissipating the heat. When the working fluid in the heat pipe 222 flows near the condenser element 221, the condenser element 221 dissipates heat from the heated heat pipe 222, absorbing the heat carried by the working fluid in the heat pipe 222. The condenser element 221 is provided with multiple heat dissipation fins to increase the contact area between the condenser element 221 and the air. This allows the cooling air flowing continuously within the cooling channel 400 to effectively cool and dissipate heat from the condenser element 221. At the same time, the cooling air can also continuously dissipate heat from the TEC cooling plate 210 and the heat pipe 222, ensuring that heat does not accumulate in the cooling channel 400, so that the overall temperature of the beauty instrument of this embodiment remains appropriate, so that this embodiment can be used for a long time.

[0057] In one embodiment, for example, as shown in Figures 2 to 4, the position of the heat pipe 222 at the heating end is lower than the position of the heat pipe 222 at the condensing element 221 in the vertical direction. In this way, when the heat pipe 222 radiator is in operation, after the working fluid in the heat pipe 222 absorbs heat, the working fluid will be evaporated into steam. Since the density of steam is less than the density of the working fluid, and the position of the heat pipe 222 at the heating end is lower, the working fluid will flow toward the heat pipe 222 at the heating end, refill the position of the steam, continue to absorb heat, and perform heat exchange with the outside. The steam in the heat pipe 222 will flow along the heat pipe 222 toward the condensing element 221. After flowing to the condensing element 221, the steam will release heat again at the condensing element 221, liquefy into working fluid, and then flow back to the position where heat is absorbed, continuing to perform heat exchange with the outside.

[0058] In one embodiment, the TEC heat dissipation unit 220 further includes a first fan 223, which can dissipate heat from the condensing element 221. Due to the large surface area of ​​the condensing element 221, the cooling air blown by the first fan 223 can effectively cool the condensing element 221, allowing the condensing element 221 to maintain a relatively low temperature, thereby cooling the working fluid flowing in the heat pipe 222.

[0059] In one embodiment, as shown in FIG5 , the optical path structure heat dissipation unit 230 includes an optical path heat sink 231 and a second fan 232. The optical path heat sink 231 can exchange heat with the light-emitting assembly 310 and the light-guiding assembly 320; the second fan 232 can dissipate heat from the optical path heat sink 231. The optical path heat sink 231 is in direct contact with the reflective assembly 330, exchanging heat with the reflective assembly 330 to cool the reflective assembly 330, thereby creating a low-temperature working environment for the light-emitting assembly 310 and reducing the heat generated by the light-emitting assembly 310. Similarly, a plurality of heat dissipation fins are provided on the light path radiator 231, that is, the light path radiator 231 has a large surface area, and cooperates with the cooling air delivered by the second fan 232 to enable the light path radiator 231 to fully exchange heat with the flowing cooling air, so as to prevent heat accumulation on the light path radiator 231, thereby cooling and dissipating the light emitting component 310 and the reflective component 330 through the light path radiator 231.

[0060] In one embodiment, for example, a heat shield is provided between the optical path structure heat dissipation portion 230 and the TEC heat dissipation portion 220. The heat shield prevents heat transfer between the optical path structure heat dissipation portion 230 and the TEC heat dissipation portion 220, thereby preventing the heat dissipation process of each from being affected. In this way, the TEC cooling plate 210 cools and dissipates heat from the light guide assembly 320, thereby ensuring the use effect of this embodiment. The TEC heat dissipation portion 220 cools and dissipates heat from the heating end of the TEC cooling plate 210, thereby ensuring the normal operation of the TEC cooling plate 210. The optical path structure heat dissipation portion 230 partially cools and dissipates heat from the optical path structure 300. The combination of the three makes the heat dissipation structure 200 of this embodiment form a complete system, thereby ensuring that there is no heat accumulation when this embodiment is in use.

[0061] Example 2

[0062] Based on Example 1, this example further improves some structures.

[0063] In one embodiment, exemplary, as shown in Figures 1 and 2, it also includes a housing 100, a cooling channel 400 is provided on the housing 100, and the cooling channel 400 is formed with an air inlet and an air outlet connected to the outside world on the housing 100. The optical path structure 300 and the heat dissipation structure 200 are both arranged in the cooling channel 400, and the optical path structure 300 and the heat dissipation structure 200 are both able to exchange heat with the cooling wind circulating in the cooling channel 400. The optical path structure 300 and the heat dissipation structure 200 are both arranged in the housing 100 and protected by the housing 100 to avoid the optical path structure 300 and the heat dissipation structure 200 from being affected by the outside world, thereby improving the stability of this embodiment. The air inlet and the air outlet connected to the outside world are provided on the housing 100, so that the air in the cooling channel 400 can be kept connected to the outside world, and the cold air from the outside world can flow in in time, and the hot air in the cooling channel 400 can also be discharged in time, thereby improving the cooling effect of the cooling channel 400.

[0064] In one embodiment, for example, a light-emitting surface is provided on the side of the light-transmitting crystal 321 away from the light-emitting component 310, and the light-emitting surface is configured as a curved surface. The curved surface configuration ensures that when the user slides the light-emitting surface against the skin, the edge of the light-transmitting crystal 321 where it connects to the housing 100 will not contact the user's skin. When the user controls the light-transmitting crystal 321 to slide across the skin, the touch feels smoother and there is no scratching. In addition, the light-transmitting crystal 321 of this embodiment can also maintain a comfortable temperature, further making the touch of the light-transmitting crystal 321 more comfortable and improving the user experience of this embodiment.

[0065] In one embodiment, for example, as shown in FIG1 , the housing 100 is provided with a light outlet, a light outlet surface is disposed within the light outlet, and the light outlet surface protrudes toward the exterior of the housing 100; the connection between the light outlet surface and the housing 100 is sealed. When using a beauty device, it is often used in conjunction with other liquid or gel-like medications to enhance their effectiveness. Sealing the connection between the light outlet surface and the housing 100 can prevent liquid or gel-like medications from seeping into the housing 100 and contaminating or damaging other structures within the housing 100.

[0066] In one embodiment, for example, a power supply is provided in the housing 100, and the power supply is electrically connected to the cooling assembly and the optical path structure 300 of the beauty instrument, and can supply power to them. The power supply is provided with a charging port that can be connected to the outside world, and the power supply is configured as a low-resistance lithium-ion battery. A power supply capable of charging and discharging is provided in the housing 100, and the power supply is used to power other structures to ensure that the present embodiment can operate normally. Before using the present embodiment, the power supply is charged through the charging port. When using, only the present embodiment needs to be taken out and used directly.

[0067] It's worth noting that, due to the large number of electrical components and the high output power of the power supply in this embodiment, the power supply generates heat on its surface during use, affecting the overall temperature within the housing 100 of this embodiment. According to the formula P = IR, where P is power, I is current, and R is resistance, the only way to reduce the heat generated by the power supply, while maintaining the same output current, is to reduce its own resistance. Therefore, using a low-resistance lithium-ion battery effectively reduces this heat generation. Furthermore, the power supply can exchange heat with the cooling air within the heat dissipation channel, further ensuring that heat is not accumulated on the power supply surface and maintaining the temperature within the housing 100 of this embodiment within a consistent range.
