Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0039] The skin care device provided in the embodiment of the present application is mainly used for caring for the skin, which may be the skin on the face, the hands, the legs, the abdomen, or other parts of the human body.

[0040] Skin care devices include, but are not limited to, phototherapy, microcurrent, and radiofrequency current devices. Phototherapy devices, such as intense pulsed light and lasers, primarily utilize specific wavelengths of light to improve skin problems. These devices can penetrate the skin's surface, reaching varying depths and affecting pigments, blood vessels, and collagen.

[0041] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a skin care device 100, including a shell 10 and a light-emitting device 20. A care head 11 is formed at one end of the shell 10, and the care head 11 is provided with a light-transmitting window; the light-emitting device 20 is arranged in the shell 10 to output care light to the skin through the light-transmitting window.

[0042] In this embodiment, the housing 10 is mainly used for the user to hold and provides a place for installing other components. In order to facilitate the user to hold, the housing 10 can be designed into an ergonomic shape, such as a streamlined shape or a handle with an anti-slip design to improve the comfort and stability of holding.

[0043] The material of the housing 10 can be selected based on different needs. For example, to reduce overall weight, a lightweight, high-strength material such as carbon fiber or aluminum alloy can be used. Considering the user's grip comfort, the surface of the housing 10 can be made of a soft-touch material such as silicone or polyurethane coating. These materials not only provide a soft touch, but also can be treated with surface treatments (such as spraying, plating, or rubber coating) to increase the anti-slip effect, thereby enhancing the user experience of the device.

[0044] In one embodiment, the skin care device 100 is a beauty instrument. The light-emitting device 20 includes at least one halogen lamp 21. The halogen lamp 21 is configured to emit near-infrared light with a wavelength of 760-1940 nm through a light-transmitting window toward the skin. When applied to the skin, this near-infrared light stimulates the synthesis of fibroblasts, which are the primary producers of collagen. Therefore, it can promote collagen production and enhance skin thickness. Furthermore, it can promote the proliferation of keratinocytes, accelerate keratin formation, and restore the skin barrier.

[0045] In addition, the light emitting device 20 can use light sources such as LED, laser diode, etc., and different wavelengths of light can be selected according to specific nursing needs, which is not limited in the embodiments of the present application.

[0046] Please refer to Figure 2 and Figure 3The skin care device 100 further comprises a controller 30 disposed within the housing 10 and electrically connected to the light emitting device 20 for controlling the light emitting device 20 to emit at least the care light with a peak wavelength between 1400 nm ± 100 nm.

[0047] In this embodiment, the controller 30 controls the light emitting device 20 to emit at least the care light with a peak wavelength between 1400 nm ± 100 nm, i.e. to emit light in the near-infrared region. Compared to visible pulsed light, light in the near-infrared region penetrates deeper, and the characteristics of light in the near-infrared region can be utilized to improve the penetration depth of light in biological tissue. Such light can penetrate the skin and tissue more deeply, providing better illumination and care effects for deep tissue. For example, the light emitting device 20 emitting at least the care light with a peak wavelength between 1400 nm ± 100 nm can penetrate through the epidermis to the dermis and heat the water molecules in the dermis, which absorb the energy of the care light to generate heat to promote collagen proliferation through thermal action, so as to increase the thickness and density of the dermis, achieving the effects of smoothing wrinkles, refining pores, and restoring skin elasticity. In addition, in the near-infrared region, the degree of scattering of photons is relatively low, which means that less energy is lost during the propagation of light, and the target area can be reached more effectively, improving the care effect while reducing energy waste.

[0048] Therefore, the light emitting device 20 emitting at least the care light with a peak wavelength between 1400 nm ± 100 nm acting on the skin can achieve the purpose of promoting the absorption of the skin to the cosmetic product, thereby greatly improving the absorption efficiency and absorption effect of the skin to the cosmetic product or medical product.

[0049] In this embodiment, the cosmetic product includes but is not limited to a cosmetic agent, a cosmetic mask, and a cosmetic patch. The medical product includes but is not limited to a medical drug and a medical patch.

[0050] It should be noted that the controller 30 can be implemented using various types of control chips or integrated circuits (IC). Common options include microcontroller 30 (MCU) chips, such as the STM32 series from STMicroelectronics or the PIC series from Microchip, which can be programmed to flexibly control the light emitting device 20 to emit at least the care light with a peak wavelength between 1400 nm ± 100 nm. In addition, a dedicated power management chip (PMIC) can also be used to handle power distribution and switching, such as the TPS series from Texas Instruments or the ADP series from Analog Devices.

[0051] In some embodiments, please refer to Figure 1 and Figure 2The skin care device 100 further includes a plurality of electrodes 80, which are arranged around the light-transmitting window, and the plurality of electrodes 80 are at least partially exposed from the housing 10 for outputting microcurrent and / or radiofrequency current to the skin.

[0052] In this embodiment, multiple electrodes 80 can output microcurrent to the skin. Microcurrent can stimulate muscle fiber contraction, increase muscle tension, and enhance muscle strength and firmness. At the same time, current stimulation of the dermis will also promote cells to produce more adenosine triphosphate (ATP), and ATP is a key substance for collagen production. Therefore, microcurrent massage of the skin can accelerate the production of collagen, thereby achieving the effect of firming, lifting and slimming the face.

[0053] In this embodiment, multiple electrodes 80 can output radio frequency current to the skin. The thermoelectric effect of the radio frequency current heats the skin to intensify the irregular movement of the active ingredients in the beauty product and forms aqueous channels in the stratum corneum, which can help promote the skin's absorption of beauty products or medical products.

[0054] It should be noted that the microcurrent output by the electrode 80 is an alternating current greater than 0uA and less than or equal to 1000uA. Microcurrent is a current at the microampere (i.e., uA) level, which is close to the natural bioelectricity of the human body. The safe limit of current acceptable to the human body is 50mA, and the microcurrent of the skin care device 100 provided in this embodiment is far lower than the limit required by the safety standard, fully ensuring the safety and reliability of the product; the frequency of the radio frequency current is 300K-300MHz, which will generate heat when passing through the skin tissue. The heat causes the collagen in the dermis to denature and shrink. The natural wound healing reaction will trigger the formation of new collagen and further skin contraction, which will have a tightening and lifting effect on the skin.

[0055] It should be noted that the multiple electrodes 80 are at least partially exposed from the shell 10, which may include a situation where the electrode 80 is protruding from the shell 10, a situation where the electrode 80 is flush with the surface of the shell 10, or a situation where the electrode 80 is recessed at a certain distance from the surface of the shell 10. The purpose is to enable the electrode 80 to output microcurrent and / or radiofrequency current to the skin during the contact between the electrode 80 and the skin.

[0056] Please refer to Figure 3 In some embodiments, the skin care device 100 further includes a gear adjustment component 40, the gear adjustment component 40 is electrically connected to the controller 30, and the gear adjustment component 40 can be switched to at least two working gears;

[0057] At least one of the following parameters corresponding to at least two working gears is different: a driving voltage amplitude of the light emitting device 20, a color temperature value of the light emitting device 20;

[0058] The controller 30 is also configured to: according to the gear information fed back by the gear adjustment component 40, control the light emitting device 20 to emit at least nursing light with a peak between 1400nm±100nm with a driving voltage amplitude and color temperature value corresponding to the gear information fed back by the gear adjustment component 40.

[0059] In this embodiment, the gear adjustment component 40 can be designed as a button, knob, dial, or touch screen, providing a variety of operation methods based on different usage scenarios and user habits. For example, the button design is simple and intuitive, suitable for quick gear adjustment; the knob or dial provides more precise mode selection, allowing the user to gradually adjust to the desired mode; and the touch screen can display detailed information about each mode, providing a more intelligent and interactive operation experience.

[0060] The gear adjustment component 40 can be manually adjusted by the user. In this embodiment, by providing different operating gears on the skin care device 100, the user can easily adjust the operating gear to the appropriate level based on their actual needs, thereby meeting their varying needs. Of course, in specific applications, as an alternative embodiment, the skin care device 100 may also be provided with only one operating gear.

[0061] As an embodiment, the driving voltage amplitude of the light-emitting device 20 corresponding to each operating position is greater than or equal to 6V and less than or equal to 12V. For example, a driving voltage amplitude of 6V, 9V, or 12V can be used. This ensures that the driving voltage of the light-emitting device 20 is within a safe voltage range and that the light-emitting device 20 can operate stably within a certain voltage range, preventing insufficient light emission due to excessively low voltage and damage due to excessively high voltage. Specifically, when the voltage is between 6V and 12V, the light-emitting device 20 can operate normally and provide a stable lighting effect, thereby ensuring the safety of the user when using the skin care device 100.

[0062] As an embodiment, the color temperature of the light emitting device 20 corresponding to each working gear is greater than or equal to 1500 K and less than or equal to 2100 K. For example, a color temperature of 1500 K, 1700 K, 1900 K or 2100 K may be used.

[0063] In this embodiment, the color temperature range is between 1500K and 2100K, ensuring that the skin care device 100 provides appropriate lighting conditions during use, ensuring the user's skin health and beauty. Specifically, lower color temperatures (approaching 1500K) provide warmer light, suitable for relaxation and skin care, while higher color temperatures (approaching 2100K) provide cooler white light, more suitable for brightening the skin or deep cleansing. This color temperature range can meet different beauty needs while avoiding the adverse effects of using too high or too low color temperatures on the skin.

[0064] Please refer to Figure 3 In some embodiments, the skin care device 100 further includes a temperature detection component 50, which is used to detect skin temperature and / or ambient temperature;

[0065] The controller 30 is also configured to: according to the temperature information fed back by the temperature detection component 50 and the gear information fed back by the gear adjustment component 40, control the light emitting device 20 to emit at least nursing light with a peak between 1400nm±100nm with a driving voltage amplitude and a color temperature value of the light emitting device 20 corresponding to the temperature information fed back by the temperature detection component 50 and the gear information fed back by the gear adjustment component 40.

[0066] In this embodiment, according to the temperature detection component 50 detecting different ranges of temperature, corresponding driving voltage values ​​or color temperature values ​​are used to drive the light-emitting device 20 to emit light. This is beneficial to ensure that the water molecules in the dermis absorb the energy of the care light to generate heat to promote collagen proliferation through thermal action, and is also beneficial to prevent the occurrence of adverse phenomena such as burns on the skin due to excessive temperature.

[0067] In some embodiments, the temperature detection component 50 includes a temperature sensor, which is arranged at the front end of the care head 11 and electrically connected to the controller 30. The temperature sensor is used to detect the temperature of the skin in real time when the light-emitting device 20 is working and transmit the detection results to the controller 30.

[0068] In this embodiment, the housing 10 directly contacts the skin, and the temperature sensor is located at the front end of the treatment head 11, closest to the treatment area. This allows for more accurate detection of the actual temperature of the skin or treatment head 11. When the light-emitting device 20 treats the skin, temperature changes first occur in the area where the treatment head contacts the skin. Therefore, temperature detection at this location can promptly reflect changes in skin temperature during the treatment process.

[0069] As an embodiment, the temperature detection component 50 is used to detect skin temperature.

[0070] In one embodiment, the temperature sensor is disposed on the electrode 80, and the electrode 80 transmits the skin temperature to the detection area of ​​the temperature detection component 50. That is, the temperature detection component 50 indirectly detects the skin temperature through the contact between the electrode 80 and the skin. Of course, this is merely exemplary and is not limited to the embodiments of the present application.

[0071] In some embodiments, the wavelength of the care light emitted by the light emitting device 20 is greater than or equal to 630nm and less than or equal to 1940nm. Light in a wavelength range has specific biological effects and is of great significance for skin care. Light of different wavelengths can penetrate different depths of the skin and act on different skin tissues, thereby achieving different care effects. For example, near-infrared light (wavelength of approximately 630nm-1400nm) can penetrate deep into the skin, promote cell metabolism and collagen production, and help improve skin elasticity and firmness. Mid-infrared light (wavelength of approximately 1400nm-1940nm) can produce a warming effect and accelerate blood circulation.

[0072] Furthermore, the wavelength of the care light emitted by the light emitting device 20 is greater than or equal to 630nm and less than or equal to 760nm, which can promote the generation of adenosine triphosphate (ATP) and act on mitochondria or fibroblasts at the same time, so that the extracellular matrix helps to fission out more collagen and form a collagen network.

[0073] In some embodiments, please refer to Figure 2 and Figure 4 The light emitting device 20 includes at least two halogen lamps 21 , and the at least two halogen lamps 21 are arranged in the housing 10 at relative intervals.

[0074] In this embodiment, at least two halogen lamps 21 are relatively spaced apart within the housing 10, which helps prevent heat accumulation and mutual interference between the halogen lamps 21 and promotes uniform light distribution. At the same time, the at least two halogen lamps 21 jointly generate light and constitute the light-emitting portion of the entire light-emitting device 20. This design not only ensures the lighting effect of the light-emitting device 20, but also makes its internal structure more reasonable and stable.

[0075] It should be understood that there are at least two halogen lamps 21, including two, three or more than three. The specific setting can be selected according to the use requirements to increase the brightness and lighting range of the light-emitting device 20. The embodiments of the present application are not limited here.

[0076] In some embodiments, please refer to Figure 4 and Figure 5 The halogen lamp 21 includes a lamp tube 22 and a filament 23 arranged in the lamp tube 22. The filament 23 includes a first spiral segment 231, a second spiral segment 232 and a non-spiral segment 233. The first spiral segment 231 and the second spiral segment 232 are respectively connected to the two ends of the lamp tube 22. The non-spiral segment 233 is connected between the first spiral segment 231 and the second spiral segment 232. The first spiral segment 231 and the second spiral segment 232 can be electrically connected to an external power supply.

[0077] The shape of the lamp tube 22 can be set according to design requirements, such as pear-shaped, cylindrical, oval, or other irregular shapes. The size of the lamp tube 22 is related to the specific application scenario. Larger lamp tubes 22 can be used for large-sized skin care devices 100, while smaller lamp tubes 22 are suitable for skin care devices 100 that require higher portability. Because the filament 23 of the halogen lamp 21 is in a heated state for a long time when the halogen lamp 21 is in operation, the lamp tube 22 also heats up. Therefore, the lamp tube 22 is usually made of a transparent material such as heat-resistant glass. It can withstand the high temperature environment when the halogen lamp 21 is in operation and has good light transmittance and corrosion resistance.

[0078] The filament 23 is typically made of tungsten wire, which has a high melting point. Tungsten filament is formed by pressing, sintering, and forging tungsten powder into a wire, which is stable at high temperatures. The size of the filament 23 is related to the luminous power and the size of the lamp tube 22. The diameter of the filament 23 is typically between 0.1 mm and 1 mm. The overall length of the filament 23 is generally consistent with the length of the lamp tube 22, ensuring uniform light distribution.

[0079] The filament 23 includes a first spiral segment 231 and a second spiral segment 232 respectively connected to the two ends of the lamp tube 22, which can be electrically connected to an external power supply to form a circuit to realize light emission. The spiral filament 23 can accommodate a longer filament 23 in a limited space, thereby increasing the surface area of ​​the filament 23 in the lamp tube 22, and more electrical energy can be converted into light energy, thereby improving the light output intensity. The segmented design allows users to flexibly adjust the parameters of the first spiral segment 231 and the second spiral segment 232 according to actual needs, such as the pitch (i.e., the distance between adjacent spirals), the number of turns, etc., so that the halogen lamp 21 can better adapt to the requirements of different power and light output positions, and when only a single halogen lamp 21 is set, the first spiral segment 231 and the second spiral segment 232 respectively irradiate the skin at different positions to meet the diverse needs of users. The pitch, diameter and number of turns of the first spiral segment 231 and the second spiral segment 232 can be adjusted according to different needs. For example, the sum of the number of turns of the first spiral segment 231 and the second spiral segment 232 is 65 turns, the pitch is 0.16 mm, and the diameter is 3 mm to adapt to the smaller size of the lamp tube 22 and avoid the halogen lamp 21 occupying too much space in the skin care device 100.

[0080] Because the middle portion of the filament 23 tends to sag at high temperatures, affecting the lifespan and luminous efficiency of the filament 23, in this embodiment, the filament 23 further includes a non-helical segment 233 connected between the first helical segment 231 and the second helical segment 232. This unevenly distributes the mass of the entire filament 23, shifting the center of gravity of the filament 23. This reduces the probability of filament 23 sag and reduces the height of the filament 23 sag. It will be appreciated that various arrangements of the first helical segment 231 and the second helical segment 232 can be employed to minimize the height of the filament 23 sag in the middle portion. For example, the first and second helical segments 231 and 232 may have the same mass, but the overall length of the first helical segment 231 may be smaller than the overall length of the second helical segment 232. In this case, the center of gravity of the filament 23 is biased toward the first helical segment 231. Alternatively, the first and second helical segments 231 and 232 may have the same overall length, but the mass of the first helical segment 231 may be smaller than the mass of the second helical segment 232. In this case, the center of gravity of the filament 23 is biased toward the second helical segment 232. Alternatively, the first and second helical segments 231 and 232 may have the same mass and overall length, while the mass distribution of the third helical segment is uneven. It should be noted that even if the first and second helical segments 231 and 232 have the same mass and overall length, at least one of the parameters, such as the number of turns, diameter, and pitch, may differ between the first and second helical segments 231 and 232. This embodiment is not limited to this.

[0081] The present invention replaces the entire spiral filament 23 with a filament 23 consisting of a first spiral segment 231, a second spiral segment 232, and a non-spiral segment 233 connected therebetween, so that the center of gravity of the filament 23 no longer falls on the middle portion of the filament 23, thereby slowing down the sagging of the filament 23 in the middle portion, thereby improving the stability and service life of the filament 23.

[0082] In some embodiments, please refer to Figure 4 and Figure 5 Two halogen lamps 21 are provided, and the two halogen lamps 21 are arranged in parallel with each other in the housing 10 at an interval.

[0083] The two halogen lamps 21 are spaced relatively apart within the housing 10, facilitating even light distribution. This allows the skin care device 100 to illuminate a larger area, thereby improving skin care efficiency. Furthermore, the two halogen lamps 21 can be powered by separate circuits, reducing the voltage requirements of a single halogen lamp 21 and enhancing the safety of the skin care device 100. Furthermore, even if one halogen lamp 21 malfunctions, the other halogen lamp 21 will continue to operate, enhancing the reliability of the skin care device 100. Furthermore, the two halogen lamps 21 are arranged side by side within the housing 10, creating a more organized layout and occupying less space, making it easier to install other components.

[0084] Please refer to Figure 4 and Figure 6 In some embodiments, the lamp tube 22 of each halogen lamp 21 is formed with a protrusion 221 , and two protrusions 221 are arranged opposite to each other at a distance.

[0085] In some embodiments, the skin care device 100 also includes a reflector 90, which is arranged on the side of the halogen lamp 21 facing away from the care head 11, and is used to reflect the light emitted by the halogen lamp 21 toward the reflector 90; the reflector 90 is provided with an arc-shaped reflecting surface corresponding to each halogen lamp 21, and each arc-shaped reflecting surface is coaxially arranged with the lamp tube 22 corresponding to the arc-shaped reflecting surface.

[0086] During the preparation of the halogen lamp 21, a certain amount of inert gas needs to be injected to inhibit evaporation of the tungsten filament and increase the service life of the halogen lamp 21. Once the through-hole where the inert gas is injected is sealed, a protrusion 221 is formed. In this embodiment, the two protrusions 221 are spaced relative to each other so that the light emitted by the halogen lamp 21 can be directly emitted from the treatment head 11, avoiding interference with the light path and affecting the treatment effect caused by the protrusions 221.

[0087] Furthermore, a reflector 90 can be installed on the side of the halogen lamp 21 facing away from the care head 11. The light emitted by the halogen lamp 21 toward the reflector 90 can be reflected back to the care head 11, thereby improving the utilization rate of the light and thus improving the efficiency of skin care. The design of the curved reflective surface further enhances the reflection effect of light. By controlling each curved reflective surface to be coaxial with its corresponding halogen lamp 21, the curved reflective surface can accurately reflect light and converge it onto the user's skin, further improving the efficiency of skin care. At this time, controlling the relative spacing of the protrusions 221 on the two halogen lamps 21 can also prevent the protrusions 221 from affecting the installation of the reflector 90, reducing the probability of the protrusions 221 affecting the reflection of light from the reflector 90.

[0088] In some embodiments, please refer to Figure 2 The skin care device 100 also includes a filter 60, which is disposed within the housing 10 and between the light-emitting device 20 and the light-transmitting window. The filter 60 is used to filter the treatment light emitted by the light-emitting device 20. The filter 60 primarily filters out unnecessary spectral components emitted by the light-emitting device 20, particularly short-wavelength ultraviolet and visible light that may cause skin irritation or discomfort, thereby allowing only light within a specific wavelength range to pass through. This not only enhances the effectiveness of phototherapy but also reduces potential damage to the skin.

[0089] Specifically, filter 60 ensures that transmitted light is concentrated within the most beneficial wavelength range, such as between 630nm and 1940nm. This wavelength is more effectively able to penetrate the skin, reaching deeper tissues and activating skin cell regeneration and repair. Filter 60 also prevents heat buildup in the device due to unnecessary light scattering, thereby protecting the device and other components from overheating and extending the device's lifespan.

[0090] In this embodiment, by using a halogen lamp 21 as the light-emitting device 20 and combining it with the use of a filter 60, the skin care device 100 can provide more accurate and efficient phototherapy services, which not only ensures the quality of light but also improves the safety and stability of the device.

[0091] In some embodiments, please refer to Figure 2 The skin care device 100 further includes a light-transmitting skin-adhering member 70 , which is installed in the light-transmitting window. The light-transmitting skin-adhering member 70 is used for allowing the care light emitted by the light-emitting device 20 to pass through and irradiate the skin.

[0092] In this embodiment, the light-transmitting skin-adhesive member 70 can be made of a transparent material to facilitate the transmission of light emitted by the light-emitting device 20. For example, it can be made of a transparent polymer material or a transparent inorganic material. Transparent polymer materials can be PC, transparent ABS, etc.; transparent inorganic materials can be glass, sapphire, ruby, diamond, etc.

[0093] As a preferred embodiment of the present application, the light-transmitting skin-mounted component 70 is made of sapphire. Sapphire is widely used in optical devices due to its high light transmittance, high-temperature resistance, and wear resistance. It effectively conducts light and maintains excellent stability during prolonged use, preventing material deformation or damage due to heat accumulation. Furthermore, sapphire's high hardness and excellent wear resistance effectively protect the skin from damage during use, effectively resisting external physical damage and extending the life of the device.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. This list of all possible embodiments is not exhaustive. Any obvious variations or modifications arising from the technical solution of the present invention remain within the scope of protection of the present invention.
