[0043] This embodiment provides a beauty device to overcome the shortcomings of related technologies, such as the low power and limited wavelength of LED lights and IPL lights, which make it difficult to effectively solve the user's skin problems.

[0044] Please see Figures 1 to 11 A beauty device includes a light-emitting component 100, a light-guiding component 200, and a reflector component 300. The light-emitting component 100 includes a halogen lamp. The light-guiding component 200 is positioned close to the light-emitting component 100. The light-guiding component 200 includes a light-transmitting crystal 210 and a filter. The filter is disposed on the side of the light-transmitting crystal 210 facing the light-emitting component 100, and the light-transmitting crystal 210 and the filter are integrally formed. Light emitted from the light-emitting component 100 can pass through the filter and the light-transmitting crystal 210 sequentially. The reflector component 300 is disposed outside the light-emitting component 100 and can reflect the light emitted from the light-emitting component 100, allowing the light to pass through the light-guiding component 200.

[0045] The reflective component 300 is arranged around the outside of the light-emitting component 100, so that after the light-emitting component 100 starts to operate, the reflective component 300 can effectively block the light emitted by the light-emitting component 100, so that most of the light is reflected in a designated direction, namely reflected towards the light-transmitting crystal 210, under the guidance of the reflective component 300. This reduces the contact between other structures and light, avoids other structures from heating up under the irradiation of light, and reduces the heat generation of the beauty device from the source.

[0046] Specifically, after the beauty device in this embodiment starts operating, the light-emitting component 100 emits light, that is, the halogen lamp emits light. After being reflected by the reflector 300, the light is conducted to the light guide component 200, and then passes through the filter and the light-transmitting crystal 210 in sequence. The filter can filter the light emitted by the halogen lamp, block unwanted stray light, and allow light of a specific wavelength to pass through the light-transmitting crystal 210 and act on the user's skin.

[0047] The light filter and the light-transmitting crystal 210 are integrally formed, meaning they are a single unit. This reduces light loss and increases the intensity of light hitting the user's skin when light passes through the light guide assembly 200 in this embodiment. In other words, light emitted from a halogen lamp experiences a 5% to 7% loss with each mirror layer. By separating the light-transmitting crystal 210 and the light filter, the light loss is 10% to 14%. However, with this integrated design, the light loss is only 5% to 7%, resulting in lower light loss and better performance.

[0048] Understandably, halogen lamps can be selected based on actual needs, as long as they address specific skin problems. For example, tungsten filament lamps can be chosen as the light source, emitting a near-infrared spectrum of 900-1800nm ​​(peak at 1300nm), which acts on the middle to deep dermis. When the surface layer of water in the skin is irradiated by platinum milk light, the distance between each water molecule increases, making the liquid more fluid. Mitochondria are powered by an enzyme bound to their cell membrane. This enzyme rotates like a molecular turbine, and being surrounded by more fluid water makes it easier for it to rotate, thus producing more ATP (adenosine triphosphate). ATP promotes cell repair and regeneration. ATP, or adenosine triphosphate, is a coenzyme and a direct source of energy for all life activities of cells in the body. It promotes cell repair and regeneration, enhances collagen fiber bioactivity, redistributes the dermis, repairs damaged skin, and makes the skin a good reflector, indirectly increasing the skin's surface refractive index, thus resulting in skin whitening and rejuvenation. Correspondingly, different halogen lamps can be used as light sources to address different skin problems.

[0049] It is important to note that the appropriate filter must be selected based on the specific halogen lamp used. Filters can absorb certain wavelengths of light. Based on the characteristics of filters, they can be used in conjunction with halogen lamps to filter and absorb unwanted stray light emitted by the lamps, resulting in purer light passing through the filter and illuminating the translucent crystal 210, thus enhancing the skin-beautifying effects of the halogen lamp.

[0050] Furthermore, halogen lamps can emit light stably and continuously. Compared to LED lights and IPL lights in related technologies, halogen lamps emit greater light intensity. After being reflected by the reflector 300, the light energy density that hits the skin is high, which can solve various skin problems more efficiently and quickly.

[0051] In one embodiment, exemplarily, such as Figures 6 to 10 As shown, the reflector assembly 300 includes a first reflector 310 and a second reflector 320. The first reflector 310 is disposed around the outside of the light-emitting assembly 100 and has a light outlet. The second reflector 320 is disposed between the light outlet and the light guide assembly 200. The first and second reflectors 310 and 320 reflect and guide the light emitted from the halogen lamp tube, directing the light to the light guide assembly 200, where it exits from the light-transmitting crystal 210, thus increasing the energy density of the light passing through the crystal 210. Furthermore, by reflecting and guiding the light to the light-transmitting assembly through the reflector assembly 300, other components are prevented from being exposed to light, avoiding overheating due to light exposure, thus protecting other components and extending their service life. This improves the overall service life and structural stability of this embodiment.

[0052] By setting a first reflector 310 on the outside of the light-emitting component 100, it is possible to prevent the light generated by the light-emitting component 100 from shining on other structures, which would cause the main body of the beauty device to heat up.

[0053] In one embodiment, exemplarily, such as Figures 8 to 10 As shown, the first reflector 310 is configured as a semi-cylindrical shape, and the axis of the first reflector 310 coincides with the axis of the light-emitting component 100. By controlling the coaxiality of the first reflector 310 and the light-emitting component 100, the guiding direction of the light generated by the first reflector 310 on the light-emitting component 100 can be controlled. By setting the first reflector 310 and the light-emitting component 100 coaxially, the light generated by the light-emitting component 100 can be uniformly reflected and emitted from the opening of the first reflector 310.

[0054] In one embodiment, exemplarily, such as Figures 8 to 10As shown, the second reflector 320 is cylindrical, with its end away from the first reflector 310 abutting against the light-transmitting crystal 210. Light emitted from the first reflector 310 enters the second reflector 320, which, being cylindrical, guides the light into the light-transmitting crystal 210 and exits from it. This effectively prevents light leakage to the outside of the second reflector 320, thus avoiding external structural heating and concentrating the light to ensure optimal cosmetic results.

[0055] It is understandable that in actual production, the first reflector 310 and the second reflector 320 can be set to any shape according to the actual shape of the light-emitting component 100 and the internal space of the beauty device, as long as they can prevent the light generated by the light-emitting component 100 from leaking out and guide the light generated by the light-emitting component 100. In this embodiment, the first reflector 310 is set to a semi-cylindrical shape and the second reflector 320 is set to a cylindrical shape to facilitate processing and reduce production costs.

[0056] It should be noted that, within a safe range, the higher the energy density of the light passing through the translucent crystal 210, the better the cosmetic effect on the skin. The energy density of the light is related to the energy and the size of the light spot; the higher the energy, the higher the energy density, and the smaller the light spot size, the higher the energy density. Since the energy emitted by the halogen lamp is fixed, simply guiding the light through the reflector 300 to the translucent crystal 210 increases the energy of the light passing through it. The reflector 300 can control the size of the light spot, further increasing the energy density of the light passing through the translucent crystal 210.

[0057] In one embodiment, exemplarily, such as Figures 8 to 10 As shown, the first reflector 310 and the second reflector 320 are sealed together. The end of the second reflector 320 away from the first reflector 310 abuts against the filter, and the second reflector 320 and the filter are sealed together. The first reflector 310 is wrapped around the outside of the halogen lamp tube, and the second reflector 320 is sealed together with the first reflector 310 and the filter. In this way, the light emitted by the halogen lamp tube can be reflected to the light guide component 200 after repeated reflection by the first reflector 310 and the second reflector 320, and then emitted from the light-transmitting crystal 210 to act on the user's skin, thereby increasing the energy density of the light in this embodiment and ensuring that the beauty device provided in this embodiment can effectively solve the user's skin problems.

[0058] In one embodiment, exemplarily, such as Figures 8 to 10As shown, the first reflector 310 is semi-cylindrical, and the light-emitting component 100 is disposed inside the first reflector 310 and coincides with the axis of the first reflector 310. By controlling the coaxiality of the halogen lamp tube and the first reflector 310, the coaxiality tolerance between the two is controlled within ±0.05mm, thereby controlling the reflection trajectory of the light emitted by the halogen lamp tube. This allows the light emitted by the halogen lamp tube to be repeatedly reflected to the light-transmitting crystal 210 under the action of the first reflector 310 and the second reflector 320, ensuring that the optical efficiency of this embodiment can reach 95% and improving the light energy density output at the light-transmitting crystal 210.

[0059] It is understandable that different reflective coatings can be applied to the inner walls of the first reflector 310 and the second reflector 320 for different halogen lamps to ensure their reflective effect, prevent light from directly passing through the inner wall and illuminating the external structure, and guide the light to the target location through reflection. The reflective coating can be flexibly selected from different materials depending on the wavelength of the light. In this embodiment, for milk light with a wavelength of 900-1800nm, an aluminum-based silver-plated reflective film is selected as the reflective coating, which can improve the optical efficiency of light reflection on the reflective surface each time and reduce heat generation.

[0060] It is worth mentioning that the efficacy of skin care is mainly determined by energy density; within a safe range, the higher the energy density, the better the effect. Energy density is affected by energy and spot size; higher energy results in higher energy density, and smaller spot size results in higher energy density. Therefore, changing energy density involves altering the energy intensity and the spot size. While ensuring the heat dissipation capacity of the light guide component, reducing the opening size of the reflector 300 is the most important method. Through the reflection of light by the reflector 300, the minimum limit for the spot size is the cross-sectional size of the reflector 300 tangent to the outer diameter of the lamp tube. This allows the light to pass through the light guide component and act on the skin, improving the cosmetic effect of this embodiment.

[0061] For example, when using tungsten filament lamps as halogen lamps, the reflective coating uses an aluminum-based silver-plated reflective film to ensure high light reflection efficiency.

[0062] In one embodiment, exemplarily, such as Figures 1 to 4As shown, the beauty device also includes a housing 500, on which a heat dissipation channel 510 is provided. The heat dissipation channel 510 has an air inlet and an air outlet communicating with the outside, and cooling air flows within the heat dissipation channel 510. The light-emitting component 100, the light-guiding component 200, and the reflector component 300 are all disposed within the heat dissipation channel 510. The cooling air flowing within the heat dissipation channel 510 can continuously exchange heat with the light-emitting component 100, the light-guiding component 200, and the reflector component 300, thereby cooling down this embodiment.

[0063] The housing 500 has an opening, into which the light-transmitting crystal 210 is embedded. When using this embodiment to address skin-related issues, the user simply holds the housing 500 and slides the light-transmitting crystal 210 back and forth against the skin, making it easy to operate. The housing 500 also protects the light-emitting component 100, the light-guiding component 200, and the reflective component 300 from damage to their internal structures.

[0064] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, the housing 500 has a protrusion, and an opening is located at the protrusion. The light-transmitting crystal 210 is sealed to the opening. The protruding light-transmitting crystal 210 allows it to contact the user's skin during use, while the housing 500 remains in contact with the user's skin, preventing scratches or abrasions and improving the user experience. When using the beauty device, it is often used in conjunction with other liquid or gel-like medications to enhance the effect. Sealing the light-transmitting crystal 210 at the opening prevents liquid or gel-like medications from seeping into the housing 500 and contaminating or damaging the circuitry.

[0065] It is understandable that sealing rubber is also provided in other locations where the housing 500 may be in contact with the outside world, to ensure that no liquid medicine will seep into the housing 500 during use and cause damage to the embodiment.

[0066] Please see Figures 1 to 5 In one embodiment, the light-emitting component 100 is disposed at the end of the heat dissipation channel 510, that is, the light-emitting component 100 is disposed at the end of the heat dissipation channel 510, the light-emitting component 100 can abut against the light-transmitting crystal 210, and cooling air flows through the heat dissipation channel 510.

[0067] In one embodiment, for example, the light-transmitting crystal 210 includes sapphire and a light filter. The light filter is disposed on the sapphire and attached to the side of the sapphire near the light-emitting component 100, while the side of the sapphire away from the light-emitting component 100 is curved. The light emitted by the light-emitting component 100 is in the near-infrared spectrum with a wavelength of 900-1800 nm. Infrared light experiences a 5%-7% loss each time it passes through a lens surface. In this embodiment, attaching the sapphire and the light filter together allows the filter to absorb stray light, reducing light loss as it passes through the sapphire and the filter. Furthermore, the curved surface on the sapphire allows it to better conform to the skin, ensuring smooth sliding without gaps, a tight fit without light leakage, and effective heat conduction for cooling, further improving the user experience of the beauty device.

[0068] Please see Figures 1 to 4 In one embodiment, the beauty device includes a cooling component 400, which is disposed within a heat dissipation channel 510 and close to the light-emitting component 100. The end of the cooling component 400 abuts against the light-transmitting crystal 210. When the light-transmitting crystal 210 generates heat under light irradiation, the cooling component simultaneously cools and dissipates heat, allowing light to pass through the crystal 210 and irradiate the user's skin, stimulating it and achieving a beauty effect. The cooling of the crystal 210 by the semiconductor cooling component 400 maintains a suitable temperature, facilitating its contact with the user's skin and enhancing the user experience. It also allows for continuous use of the beauty device without concerns about overheating.

[0069] It is understood that the cooling component can cool the light-emitting component 100 and the light-guiding component 200. Thus, when using the beauty device of this embodiment, the cooling component can lower the temperature of the device, enabling it to operate stably for extended periods, meeting the user's needs, and further improving the efficiency of this embodiment in addressing various skin problems.

[0070] In one embodiment, exemplarily, such as Figures 4 to 7 As shown, the cooling assembly includes a TEC cooling plate 420 and a TEC cooler 410. The cooling end of the TEC cooler 410 contacts the filter, and the heating end of the TEC cooler 410 contacts the TEC cooling plate 420. The TEC cooler 410 cools and dissipates heat from the filter. The filter and the light-transmitting assembly are integrally formed, meaning the TEC cooler 410 cools and dissipates heat from the light-transmitting crystal 210, thus controlling the temperature of the light-transmitting crystal 210. Since the light-transmitting crystal 210 is in direct contact with the user's skin, preventing the temperature of the light-transmitting crystal 210 from becoming too high or too low improves the user experience. When the user places the light-transmitting crystal 210 on their skin, the touch is warmer and more comfortable.

[0071] It should be noted that the light-transmitting crystal 210 is in contact with both the reflector 300 and the TEC cooler 410. Since the reflector 300 contains a halogen lamp, it continuously generates heat when exposed to light, and this heat is also radiated to the light-transmitting crystal 210. To prevent the TEC cooler 410 and the reflector 300 from interfering with each other, a gap is provided between them. This allows them to work together to control the temperature of the light-transmitting crystal 210.

[0072] It is understood that the cooling capacity of the TEC cooler 410 is related to the voltage of the power supply component connected to the TEC cooler 410. The higher the voltage, the stronger the TEC cooling capacity. In this way, the cooling capacity of the TEC cooler 410 can be controlled more flexibly by voltage, thereby controlling the temperature of the light-transmitting crystal 210, making this embodiment more convenient and flexible to use.

[0073] In one embodiment, exemplarily, such as Figures 4 to 7 As shown, the cooling assembly also includes heat dissipation fins 440 and liquid cooling pipes 430. Cooling medium flows through the liquid cooling pipes 430, which can exchange heat with the heat dissipation fins 440 and the TEC cooler 420. The liquid cooling pipes 430 pass sequentially through the TEC cooler 420 and the heat dissipation fins 440, forming a circulation path. When the cooling end of the TEC cooler 410 cools the filter, the heating end also generates heat. The TEC cooler 420 can cool and dissipate heat from the heating end of the TEC cooler 410. Furthermore, the liquid cooling pipes 430 pass through the TEC cooler 420 and the heat dissipation fins 440, and the continuously flowing liquid cooling medium within the liquid cooling pipes 430 can absorb the heat from the TEC cooler 420, cooling the TEC cooler 420 and ensuring the effective heat dissipation of the TEC cooler 410 by the TEC cooler 420. After the liquid cooling medium in the liquid cooling pipe 430 absorbs heat at the TEC cooling fin 420, it transfers the heat to the heat dissipation fins 440. The heat dissipation fins 440, with their large surface area, exchange heat with the cool air in the air to dissipate heat. In this way, the cooling system of the cooling components in this embodiment is complete and has a good heat dissipation effect.

[0074] The number of heat dissipation fins 440 is multiple and can be specifically set according to actual conditions. In this embodiment, two adjacent heat dissipation fins 440 are spaced apart to form a flow guide channel, and the axis of the flow guide channel is parallel to the axis of the heat dissipation channel 510. This improves the smoothness and stability of the gas flow through the heat dissipation channel 510 and the flow guide channel, ensuring the stability of the gas flowing over the surface of each heat dissipation fin 440, thereby improving the heat dissipation efficiency of the heat dissipation fins 440, and thus effectively improving the heat dissipation efficiency and stability of the cooling assembly 400.

[0075] It is understandable that by increasing the number of heat dissipation fins 440, the heat conduction efficiency can be further improved, thereby further improving the heat dissipation efficiency of the cooling component 400.

[0076] It should be noted that the TEC cooling element 420, i.e., a semiconductor cooling element, operates with one side cooling and the other heating during operation. In this embodiment, the cooling side of the TEC cooling element 420 is attached to the light-transmitting crystal 210, while the liquid cooling module cools and dissipates heat from the heating side of the TEC cooling element 420. In this way, the TEC cooling element 420 maintains a suitable temperature for the light-transmitting crystal 210, allowing the user to directly attach the crystal 210 to the skin, improving the cooling and heat dissipation capabilities of this embodiment and thus enhancing the user experience of the beauty device.

[0077] It is important to note that the cooling capacity of the TEC cooling element 420 is affected by the applied voltage; that is, the higher the voltage supplied to the TEC cooling element 420, the stronger its cooling capacity. Furthermore, this embodiment can also include a control component to regulate the voltage of the TEC cooling element 420. When the temperature of the light-transmitting crystal 210 is high, increasing the voltage enhances the cooling capacity of the TEC cooling element 420; conversely, decreasing the voltage reduces the temperature. By controlling the TEC cooling element 420, the light-transmitting crystal 210 can be maintained at a suitable temperature, further improving the heat dissipation capacity of this embodiment and enhancing the user experience of the beauty device.

[0078] It is worth mentioning that the heat dissipation effect of the heated surface of the TEC cooling chip 420 will have a reverse effect on the cooling effect of the side being cooled. In this embodiment, since the tungsten filament lamp heat dissipation structure is arranged adjacent to the TEC cooling chip 420, in order to prevent the heat generated by the tungsten filament lamp heat dissipation from interfering with the heat dissipation effect of the TEC cooling chip 420, the two are separated by spatial isolation and heat insulation so that they do not affect each other and operate independently, ensuring that the sapphire in contact with the user's skin receives a good cooling effect.

[0079] like Figures 4 to 6As shown, in one embodiment, a cooling component 600 is also provided within the heat dissipation channel 510. The cooling component 600 includes a fan 610, which drives cooling air to flow along the heat dissipation channel 510. The fan 610 ensures a stable flow of cooling air within the heat dissipation channel 510 for an extended period, thereby improving the heat exchange efficiency of the reflective component 300 and the semiconductor cooling component 400.

[0080] In one embodiment, for example, the housing 500 of the beauty device has an upper end and a lower end. A light-transmitting crystal 210, a light-emitting component 100, a reflective component 300, and a semiconductor cooling component 400 are sequentially arranged from the upper end to the lower end of the housing 500. A heat dissipation channel 510 extends from the upper end of the housing 500 to the lower end. Correspondingly, an air inlet is located at the connection between the heat dissipation channel 510 and the upper end of the housing 500, and an air outlet is located at the connection between the heat dissipation channel 510 and the lower end of the housing 500. Thus, when cooling air flows through the heat dissipation channel 510, it can flow from the upper end of the housing 500 to the lower end, cooling each part sequentially, starting with the light-emitting component 100 which experiences significant heat generation.

[0081] Of course, as a handheld device, the cooling airflow in the heat dissipation channel 510 can also be set to flow from the handheld part to the non-handheld part, so that the handheld part of the beauty device can maintain a suitable temperature and avoid the handheld part being too hot, which would affect the user's experience.

[0082] In one embodiment, for example, a power component is provided on the liquid cooling pipe 430, which can drive the liquid cooling medium to flow along the liquid cooling pipe 430. By driving the liquid cooling medium to flow along the liquid cooling pipe 430, the heat dissipation capacity of the liquid cooling pipe 430 is improved. For example, the power component can be set as a water pump, which increases the flow rate of the liquid cooling medium, improves the heat dissipation capacity, and ensures stable and reliable operation.

[0083] In one embodiment, for example, a power source is provided within the housing 500. This power source is electrically connected to and supplies power to the cooling assembly and the light-emitting assembly 100. The power source has a charging port that allows it to communicate with the outside world, and it is a low-resistance lithium-ion battery. The charging and discharging power source within the housing 500 supplies power to other structures, ensuring the normal operation of this embodiment. Before using this embodiment, the power source is charged via the charging port. When in use, simply remove the embodiment and use it directly.

[0084] It is worth mentioning that, due to the large number of electrical components and the high output power of the power supply in this embodiment, heat is generated on the surface of the power supply during use, affecting the overall temperature inside the casing 500 of this embodiment. According to the formula P = I...2 R, where P is power, I is current, and R is resistance. As shown in the formula, to reduce the heat generated by the power supply while keeping the output current constant, the only way is to reduce the resistance of the power supply itself. Therefore, the power supply is set to a low-resistance lithium-ion battery to reduce its heat generation. Furthermore, the power supply can exchange heat with the cooling air within the heat dissipation channel 510, further ensuring that heat does not accumulate on the surface of the power supply and maintaining the temperature within the casing 500 of this embodiment within a suitable range.
