Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a skin care device. Background Technology

[0002] In recent years, with the rapid development of China's economy, the advancement of science and technology, and the continuous improvement of living standards, people are not only pursuing a higher quality of life in terms of material and spiritual well-being, but also paying more attention to skin care. Among these, skin care devices, as instruments used to regulate and improve skin condition, can stimulate the activity of skin cells at a deep level, thereby promoting skin metabolism and cell proliferation, and delaying facial aging.

[0003] However, existing skin care devices generally suffer from the drawback of limited functionality. For example, skin care devices often only use one of the following technologies to achieve beauty functions: radio frequency technology, microcurrent technology, or infrared technology. Although they can achieve some effects, their functions are limited and cannot meet people's skin care needs, resulting in unsatisfactory beauty results. Utility Model Content

[0014] The controller also includes a light-emitting device adjustment unit, which is electrically connected to the temperature detection module and the light-emitting device, respectively, and is used to receive the temperature detection signal input by the temperature detection module and adjust the operating voltage value of the light-emitting device according to the temperature detection signal.

[0015] In some embodiments, the frequency of the radio frequency signal output by the radio frequency operating module is in the range of 0.8MHz to 3.5MHz, and / or,

[0016] The peak wavelength of the light output by the optical working module is in the range of 1400nm ± 100nm, and / or,

[0017] The wavelength of the light emitted by the optical working module is in the range of 630nm to 670nm.

[0018] In some embodiments, the skin care device further includes a radio frequency signal detection module electrically connected to the controller, which is used to detect the frequency of the radio frequency signal when the radio frequency working module is working, and transmit the detection result to the controller; the controller is also used to adjust the power of the radio frequency working module according to the detection result.

[0019] In some implementations, the controller further includes:

[0020] A frequency adjustment unit is connected to both the electrode and the radio frequency signal detection module. The frequency adjustment unit receives the frequency detection signal input from the radio frequency signal detection module and adjusts the operating voltage of the electrode according to the frequency detection signal.

[0021] In some embodiments, the skin care device further includes a cooling element electrically connected to the controller for generating cooling energy to cool the skin during and / or after the operation of the radio frequency working module and the optical working module.

[0022] In some embodiments, the skin care device further includes an emitting element, which includes a blue light emitting element or a green light emitting element.

This synergy leverages the advantages of both, enhancing the skincare effect. For example, the heating effect of the RF current can enhance the penetration depth of phototherapy, improving the skincare effect of the light on the skin tissue. Simultaneously, phototherapy can promote the regeneration and repair of skin cells under the influence of the RF current, further improving skin firmness and elasticity, and enhancing the skincare efficacy of the device.

[0035]

[0036] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0040] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0041] This utility model proposes a skin care device 100, which is mainly used for skin care. The skin can be facial skin, hand skin, leg skin, abdominal skin, or skin from other parts of the human body.

[0042] Please see Figures 1 to 6 The skin care device 100 provided in Embodiment 1 of this application includes: a working head 101, a radio frequency working module 102, a light working module 103, and a controller 104.

[0043] The working head 101 has a front end that can contact the skin to efficiently deliver the energy generated by the radio frequency module 102 and the optical module 103 into the skin tissue. Specifically, when the radio frequency module 102 generates radio frequency current, the contact between the working head 101 and the skin allows the radio frequency current generated by the radio frequency module 102 to act more directly on the deeper tissues of the skin, such as the dermis. Similarly, the light of a specific wavelength emitted by the optical module 103 can also be more effectively irradiated onto the skin surface and deeper layers through the working head 101, achieving the function of skin care.

[0044] It's important to note that the working head 101 is not only the point of physical contact but also a crucial medium for energy transfer. Furthermore, the working head 101 can integrate multiple functions to achieve multi-functional skin care. Besides transmitting radio frequency current and light, the working head can also perform massage, cleansing, and absorption functions. For example, the working head 101 can massage the skin through vibration or rotation, promoting blood circulation and metabolism. Simultaneously, the working head 101 can be used in conjunction with skincare products to deliver nutrients deeper into the skin, enhancing the absorption of the skincare products.

[0045] Please continue reading. Figure 2 and Figure 3 The radio frequency working module 102 includes several electrodes 1021 for outputting radio frequency current to the skin.

[0046] The radio frequency (RF) module 102 is a crucial component of the skin care device, primarily responsible for generating and outputting RF current. The circuitry generates RF signals of specific frequency and intensity, and the electrodes are key components for delivering the RF current to the skin. The presence of several electrodes 1021 allows the RF current to be applied more evenly to the skin. The number of electrodes can be adjusted according to the device's design and functional requirements. Multiple electrodes can be distributed in different locations to achieve precise care for different skin areas. For example, some devices may have multiple electrodes placed at different points on the working head to simultaneously perform RF treatment on a large area of ​​skin.

[0047] It's important to note that when the electrodes 1021 deliver radiofrequency current to the skin, this current generates heat within the skin tissue. This heat is primarily concentrated in the dermis because the frequency and characteristics of the radiofrequency current allow it to penetrate the epidermis and reach the dermis. The collagen in the dermis contracts upon heating, resulting in firmer skin. Furthermore, in addition to the immediate firming effect, the radiofrequency current stimulates collagen regeneration. Long-term radiofrequency treatments can promote the production of new collagen by fibroblasts in the dermis, increasing skin elasticity and thickness. This collagen regeneration effect is continuous, gradually improving skin quality over time.

[0048] Please continue reading. Figure 6 and Figure 7 The optical working module 103 includes a light-emitting device 1031, and the optical working module 103 can be used to emit light with wavelengths between 630nm and 1940nm.

[0049] The light-emitting device 1031 in the light-operating module 103 is the core component for generating light of a specific wavelength. The light-emitting device 1031 may include a light-emitting diode (LED), a laser diode, etc. The light-emitting device 1031 has advantages such as high efficiency, stability, and long lifespan, and can continuously emit light of the desired wavelength. The light-emitting device 1031 may include at least one halogen lamp 1031a for heating the skin in the corresponding treatment area of ​​the skin care device 100 to achieve skin care.

[0050] The performance of the 1031 light-emitting device directly affects the effectiveness of the light-operating module. For example, parameters such as luminous intensity, wavelength stability, and spectral purity are all important indicators for evaluating the quality of the light-emitting device. A high-quality light-emitting device can ensure that the output light has sufficient intensity and stability to achieve effective skin care.

[0051] The light-emitting module 103 can emit light with wavelengths between 630nm and 1940nm. Light within this wavelength range has specific biological effects and is significant for skin care. Different wavelengths of light can penetrate different depths of the skin, acting on different skin tissues to achieve different skin care effects. For example, near-infrared light (wavelength approximately 630nm-1400nm) can penetrate deep into the skin, promoting cell metabolism and collagen production, helping to improve skin elasticity and firmness. Mid-infrared light (wavelength approximately 1400nm-1940nm) can produce a warming effect, accelerating blood circulation. Wavelengths of 630-760nm can promote the production of adenine triphosphate (ATP) and act on mitochondria or fibroblasts, enabling the extracellular matrix to break down and produce more collagen, forming a collagen network.

[0052] Light with wavelengths between 630nm and 1940nm can stimulate the activity of skin cells, promote cell regeneration and repair, and improve skin texture and color.

[0053] Please continue reading. Figure 4 The controller 104 is electrically connected to the radio frequency (RF) module 102 and the optical module 103. The controller 104 outputs control commands to control the simultaneous operation of the RF module 102 and the optical module 103 for applying light irradiation and RF current to the skin. Specifically, the controller may include a frequency adjustment unit 1042 and a light-emitting device adjustment unit 1041. The controller 104 can adjust the RF module 102 by adjusting the frequency adjustment unit 1042, and the controller 104 can also adjust the optical module 103 by adjusting the light-emitting device adjustment unit 1041.

[0054] The controller 104 is electrically connected to the radio frequency (RF) module 102 and the optical module 103, enabling effective communication and control between the controller 104 and these two modules. Control commands may include start / stop commands, mode selection commands, parameter adjustment commands, etc. For example, the controller 104 can send a start command to cause the RF module 102 and the optical module 103 to start working simultaneously; it can also send parameter adjustment commands to adjust parameters such as the intensity and frequency of the RF current emitted by the RF module 102, and the intensity and wavelength of the light output by the optical module 103.

[0055] In some implementations, if the radio frequency module 102 and the optical module 103 start operating within a preset time period, such as within 15 seconds, it can be determined that the radio frequency module 102 and the optical module 103 are operating simultaneously. This time interval setting ensures the synergistic effect of the two modules in terms of function, while also allowing for some degree of difference in actual operating time.

[0056] Please continue reading. Figure 1 and Figure 6 The working head 101 has a light-transmitting window 1011 at its front end. The light-transmitting window 1011 is provided with a light-transmitting element 1012. The light-transmitting element 1012 is located on the side of the light-emitting device 1031 facing the skin. The light emitted by the light-emitting device 1031 forms light with a wavelength between 630nm and 1940nm after passing through the light-transmitting element 1012.

[0057] The working head 101 has a light-transmitting window 1011 at its front end, which allows light to directly illuminate the skin surface, thereby enabling the phototherapy module 103 to provide skin care. The light-transmitting window 1011 serves as a light propagation channel, ensuring that the light emitted by the light-emitting device 1031 can reach the skin smoothly. The light-transmitting window 1011 is equipped with a light-transmitting element 1012, which filters and conducts light. The light-transmitting element 1012 is located on the side of the light-emitting device 1031 facing the skin, and can receive the light emitted by the light-emitting device 1031, process it, and then transmit it to the skin. The light-transmitting element 1012 has good light transmittance, allowing specific wavelengths of light to pass through while blocking other unwanted wavelengths or interfering light.

[0058] Several electrodes 1021 are disposed around the light-transmitting window 1011.

[0059] Please continue reading. Figure 3 and Figure 6 By placing several electrodes 1021 around the light-transmitting window 1011, the electrodes 1021 and the light-transmitting window 1011 can work collaboratively within a limited space without interfering with each other. Specifically, the electrodes 1021 output the radio frequency current from the radio frequency working module 103 around the light-transmitting window 1011, while the light-transmitting window 1011 allows the light output from the light working module 103 to irradiate the skin. Their proximity allows the radio frequency current and light to interact on the skin surface and in superficial tissues, resulting in better skin care effects. Furthermore, placing the electrodes 1021 around the light-transmitting window 1011 can compensate for the energy attenuation of the light output from the light working module 103 at its periphery (the energy is lower around the light port due to refraction, reflection, and scattering), thereby enhancing the skin care efficacy of the device.

[0060] In some embodiments, the electrodes also deliver microcurrents to the skin.

[0061] Microcurrents can reach the muscle layer, stimulating repeated contractions and relaxation of the skin muscles, restoring muscle vitality, improving skin tension and elasticity, helping to lift the face to a V-shape, improve facial contours, improve sagging skin, and reduce puffiness.

[0062] The light working module emits light with wavelengths between 630nm and 1940nm. Combined with the radio frequency current and microcurrent output from the electrodes, the three act on the skin, which not only promotes collagen production and the formation of a collagen network, but also lifts the face and reduces fine lines. The three work together to provide synergistic care for the skin.

[0063] Please continue reading. Figure 3 and Figure 4 The skin care device 100 also includes a temperature detection module 105, which is located at the front end of the working head 101 and electrically connected to the controller 104. The temperature detection module 105 is used to detect the target temperature of the skin and transmit the detection result to the controller 104 when the radio frequency working module 102 and the light working module 103 are working.

[0064] The controller 104 in the skin care device 100 is also used to adjust the power of the light working module 103 and / or the radio frequency working module 102 according to the detection results.

[0065] The working head 101 is in direct contact with the skin. The temperature detection module 105 is located at the front end of the working head 101, which is closest to the treatment area, thus enabling more accurate detection of the actual temperature of the skin or the working head 101. When the radio frequency working module 102 and the light working module 103 treat the skin, temperature changes first occur in the area in contact with the working head. Therefore, temperature detection at this location can promptly reflect changes in skin temperature during the treatment process.

[0066] It should be noted that when the temperature detection module 105 detects the temperature of the care area, it can detect the temperature of the light-transmitting element 1012 in the working head 101, and use the temperature of the light-transmitting element 1012 as the target temperature for skin temperature detection. When the temperature detection module 105 detects the temperature of the care area, it can also directly detect the temperature of the area closest to the skin surface, thereby determining the target skin temperature obtained by the temperature detection module 105. It can also detect the temperature of the electrode 1021 in contact with the skin, and use the temperature of the electrode 1021 as the target temperature for skin temperature detection.

[0067] Please continue reading. Figure 3 and Figure 4 The temperature detection module 105 includes a temperature sensor 1051 disposed on the electrode 1021.

[0068] The controller 104 also includes a light-emitting device adjustment unit 1041, which is electrically connected to the temperature detection module 105 and the light-emitting device 1031 respectively. It is used to receive the temperature detection signal input by the temperature detection module 105 and adjust the operating voltage value of the light-emitting device 1031 according to the temperature detection signal.

[0069] The electrodes 1021 are in close contact with the skin during operation, allowing the temperature sensor 1051 mounted on the electrodes 1021 to more directly sense changes in skin temperature. Since the radio frequency module 102 outputs radio frequency current to the skin through the electrodes 1021, the temperature change in the treated area is significant. Therefore, placing the temperature sensor 1051 here allows for more accurate monitoring of the temperature information of the skin care device 100 during the treatment process.

[0070] The light-emitting device adjustment unit 1041 in the controller 104 is electrically connected to the temperature detection module 105 and the light-emitting device 1031, respectively. Therefore, the light-emitting device adjustment unit 1041 can receive the temperature detection signal input from the temperature detection module 105. This temperature detection signal contains the current skin temperature information, which is an important basis for adjusting the working state of the light-emitting device. After receiving the temperature detection signal, the light-emitting device adjustment unit 1041 can understand the changes in skin temperature and make corresponding adjustments to the light-emitting device.

[0071] Therefore, the temperature sensor 1051 in the temperature detection module 105 is mounted on the electrode 1021, enabling more accurate monitoring of skin temperature changes. The light-emitting device adjustment unit 1041 in the controller 104 receives the temperature detection signal and adjusts the operating voltage of the light-emitting device 1031 according to the signal, thereby achieving precise control of skin temperature and optimization of phototherapy effects, improving the safety and effectiveness of the skin care device.

[0072] In one implementation, the frequency of the radio frequency signal output by the radio frequency working module is in the range of 0.8MHz to 3.5MHz, and / or, the peak wavelength of the light emitted by the optical working module is in the range of 1400nm ± 100nm, and / or,

[0073] The wavelength of the light emitted by the optical working module is in the range of 630nm to 670nm.

[0074] Radio frequency (RF) signals with frequencies ranging from 0.8 MHz to 3.5 MHz can act on multiple layers of the skin at different depths. This allows RF signals in this frequency range to generate a thermal effect within the skin tissue at varying depths. When the RF signal acts on the skin, it induces molecular vibrations in the skin tissue at different depths, generating heat. This thermal effect can stimulate collagen contraction and regeneration, promoting skin firmness and elasticity. Simultaneously, appropriate thermal effects can also improve blood circulation in the skin, increase nutrient supply, and promote skin cell metabolism.

[0075] Light with wavelengths peaking in the range of 1400nm ± 100nm can interact more effectively with components such as moisture and collagen in skin tissue, producing specific biological effects. Thus, light can more effectively heat the moisture in skin tissue, thereby causing collagen contraction and regeneration. Simultaneously, it can stimulate skin cell activity, promoting cell metabolism and repair.

[0076] Light with wavelengths in the range of 630nm to 670nm can promote cell metabolism, increase collagen production, improve skin elasticity and firmness, and also promote the production of adenosine triphosphate (ATP). At the same time, it acts on mitochondria or fibroblasts, enabling the extracellular matrix to help break down more collagen and form a collagen network.

[0077] Please continue reading. Figure 4 The skin care device 100 also includes a radio frequency signal detection module 106, which is electrically connected to the controller 104. This module detects the frequency of the radio frequency signal when the radio frequency working module 102 is operating and transmits the detection result to the controller 104. The controller 104 also adjusts the power of the radio frequency working module 102 based on the detection result.

[0078] The radio frequency (RF) signal detection module 106 is electrically connected to the controller 104, enabling the RF signal detection module 106 to transmit the detected information to the controller 104 in real time. Through this electrical connection, the RF signal detection module 106 can quickly and accurately transmit relevant data of the RF signal to the controller 104 in the form of electrical signals, ensuring that the controller 104 can obtain the working status information of the RF signal detection module 106 in a timely manner.

[0079] When the radio frequency (RF) module 102 is operating, the RF signal detection module 106 can detect the frequency of the RF signal. The frequency of the RF signal is an important parameter that directly affects the skin care effect of the RF module 102. Different frequencies result in different penetration depths and modes of action of RF energy in the skin. By detecting the frequency of the RF signal, the RF signal detection module 106 can provide the controller with key information about the operating status of the RF module 102.

[0080] The radio frequency signal detection module 106 transmits the detected radio frequency signal frequency result to the controller 104. To ensure that the controller can understand the operation status of the radio frequency working module at any time, the radio frequency signal detection module 106 can detect and transmit the signal in real time. The controller 104 can adjust the control strategy of the radio frequency working module 102 in a timely manner according to the received detection results to achieve better skin care results.

[0081] The controller 104 adjusts the power of the RF operating module 102 based on the detection results transmitted by the RF signal detection module 106. When the controller 104 receives the RF signal frequency information detected by the RF signal detection module 106, it determines whether the power of the RF operating module needs to be adjusted. If the detection results show that the RF signal frequency deviates from the preset ideal frequency, the controller 104 can adjust the power of the RF operating module 102 to bring the RF signal frequency back to a suitable range.

[0082] Thus, the radio frequency signal detection module 106 in the skin care device 100 works in conjunction with the controller 104 to detect the frequency of the radio frequency signal and transmit the result to the controller 104. The controller 104 then adjusts the power of the radio frequency working module 102 according to the detection result, thereby achieving precise control of the skin care device, optimizing the skin care effect, and ensuring the safe and stable operation of the device.

[0083] Please continue reading. Figure 4 The controller of the skin care device 100 also includes a frequency adjustment unit 1042.

[0084] The frequency adjustment unit 1042 is connected to the electrode 1021 and the radio frequency signal detection module 106 respectively. The frequency adjustment unit 1042 can be used to receive the frequency detection signal input by the radio frequency signal detection module 106 and adjust the working voltage of the electrode 1021 according to the frequency detection signal.

[0085] The controller of the skin care device 100 includes a frequency adjustment unit 1042. The frequency adjustment unit 1042 is connected to both the electrode 1021 and the radio frequency signal detection module 106, enabling it to play a crucial role in the operation of the radio frequency working module 102. The frequency adjustment unit 1042 receives the frequency detection signal from the radio frequency signal detection module 106, which detects the operating frequency of the radio frequency working module 102, and adjusts the operating voltage of the electrode 1021 accordingly, thereby adjusting the frequency of the radio frequency signal output by the radio frequency working module 102.

[0086] The frequency adjustment unit 1042 receives a frequency detection signal input from the radio frequency signal detection module 106. This frequency detection signal may include information about the frequency of the radio frequency signal currently output by the radio frequency operating module 102. After receiving the radio frequency signal frequency information, the controller 104 can determine the real-time operating state of the radio frequency operating module 102, such as changes in the radio frequency signal frequency. Specifically, adjusting the operating voltage of the electrode 1021 according to the frequency detection signal can directly affect the frequency of the radio frequency signal output by the radio frequency operating module 102. There is a corresponding relationship between the operating voltage of the electrode 1021 and the frequency of the radio frequency signal. By adjusting the operating voltage of the electrode 1021, the generation mechanism of the radio frequency signal can be changed, thereby adjusting the frequency of the radio frequency signal.

[0087] It should be noted that adjusting the operating voltage of electrode 1021 to control the radio frequency signal frequency can optimize skin care effects. Different skin conditions and care needs may require different radio frequency signals. By precisely adjusting the operating voltage of the electrode to control the radio frequency signal frequency, the radio frequency module can output the radio frequency signal most suitable for the current skin care needs. Therefore, the frequency adjustment unit 1042 in the controller 104 of the skin care device 100 can receive the frequency detection signal input from the radio frequency signal detection module 106 and adjust the operating voltage of electrode 1021 according to the signal, thus achieving precise control of the radio frequency signal frequency output by the radio frequency module 102. This helps optimize skin care effects, meet the needs of different users, and ensure the stable operation of the device.

[0088] Please continue reading. Figures 6 to 8 The skin care device 100 also includes a cooling component 107.

[0089] The cooling component 107 is electrically connected to the controller 104 and is used to generate cooling energy to cool the skin during and / or after the operation of the radio frequency working module 102 and the optical working module 103.

[0090] The cooling element 107 is electrically connected to the controller 104, enabling the controller 104 to effectively control the cooling element 107. Through this electrical connection, the controller 104 can send commands to start or stop the operation of the cooling element 107, and adjust its operating parameters, such as cooling intensity.

[0091] The main function of the cooling component 107 is to generate cooling energy during and / or after the operation of the radio frequency module 102 and the optical module 103. This cooling energy can cool the skin, thereby providing cooling and soothing effects to the skin during and / or after the operation of the skin care device 100.

[0092] For example, when the radio frequency (RF) module 102 and the optical module 103 are operating, the skin may heat up due to the thermal effects of the RF current and the light irradiation. The cooling energy generated by the cooling element 107 can promptly lower the skin temperature, preventing overheating and damage. Simultaneously, the cooling energy can alleviate discomfort during skincare, improving the user experience. When the RF module 102 and the optical module 103 are operating, the cooling energy generated by the cooling element 107 can cool the skin in real time. The RF current and light irradiation may cause the skin temperature to rise, but the cooling energy can counteract this thermal effect, maintaining the skin temperature within a relatively stable range.

[0093] After the radio frequency module 102 and the light module 103 have finished operating, the cooling energy generated by the cooling element 107 can continue to cool the skin. This helps the skin return to its normal temperature and reduces post-treatment discomfort. For example, after phototherapy, the skin may experience slight heat and redness due to light exposure. The cooling energy from the cooling element can alleviate this phenomenon, allowing the skin to recover to its normal state more quickly. At the same time, the cooling energy can also promote skin metabolism and enhance the skin's self-repair ability.

[0094] Please continue reading. Figure 8 The skin care device 100 also includes an emitting element 108, which may include a blue light emitting element 1081 or a green light emitting element 1082. The blue light emitting element 1081 or the green light emitting element 1082 is disposed between the light-transmitting element 1012 and the light-emitting device 1031, and the blue light signal or green light signal emitted by the blue light emitting element 1081 or the green light emitting element 1082 passes through the light-transmitting element 1012 to irradiate the skin.

[0095] And / or, the light-emitting device 1031 may include at least one halogen lamp 1031a.

[0096] The skin care device 100 also includes an emitting element 108, which may include a blue light emitting element 1081 or a green light emitting element 1082. The blue light emitting element 1081 or the green light emitting element 1082 can be LED lights used to output corresponding blue light and green light signals. The blue light and green light signals have specific functions in skin care. Specifically, blue light signals typically have antibacterial and anti-inflammatory effects and can be used to treat skin conditions such as acne. Green light signals are effective in soothing sensitive skin and reducing redness and swelling.

[0097] A blue light emitting element 1081 or a green light emitting element 1082 is disposed between the light-transmitting element 1012 and the light-emitting device 1031, which can ensure that the blue light signal or green light signal can effectively pass through the light-transmitting element to irradiate the skin. The light-transmitting element 1012 plays the role of conducting light, and can also filter and adjust the light to a certain extent, so that the light irradiating the skin is more suitable for the needs of skin care.

[0098] The blue light emitting element 1081 or the green light emitting element 1082 emits blue light or green light signals that pass through the light-transmitting element 1012 to irradiate the skin, thereby directly acting on the skin surface and superficial tissues to exert its therapeutic effect. The preset wavelength blue light and green light signals can be absorbed by different cells and tissues in the skin, thereby producing corresponding biological effects.

[0099] The light-emitting device 1031 may include at least one halogen lamp 1031a. The halogen lamp 1031a is a common light source with high brightness and stability. In the skin care device 100, the halogen lamp 1031a can serve as part of the light-emitting device, emitting light of a preset wavelength for skin care. For example, the halogen lamp 1031a can emit light with wavelengths between 630nm and 1940nm. Light within this wavelength range has significant skin care effects, such as promoting cell regeneration, enhancing skin immunity, and promoting collagen production. The high brightness of the halogen lamp 1031a ensures sufficient light intensity for effective skin care. Simultaneously, the stability of the halogen lamp guarantees the reliability of the device during long-term use.

[0100] Therefore, the emitting element 108 in the skin care device 100 includes a blue light emitting element 1081 or a green light emitting element 1082, disposed between the light-transmitting element 1012 and the light-emitting device 1031. The emitted blue light signal or green light signal passes through the light-transmitting element 1012 to irradiate the skin, thereby achieving the skin care function. The light-emitting device 1031 may include at least one halogen lamp 1031a, which emits light of a specific wavelength as a light source for skin care.

[0101] The above are merely specific embodiments of this application. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
