[0052] The embodiment of the present application proposes a skin care device, which comprises:
[0053] A shell assembly 100, part of the shell assembly 100 forms a beauty head 101, and the beauty head 101 is provided with a light outlet 101a;
[0054] A light-transmitting piece 200 is arranged at the light outlet 101a, and the light-transmitting piece 200 is at least partially exposed to the shell assembly 100;
[0055] A light-emitting device 300 is installed in the shell assembly 100 and irradiates light towards the light-transmitting piece 200, so as to perform light irradiation care on the skin through the light-transmitting piece 200;
[0056] A refrigeration component 400 is located inside the housing assembly 100 and is in thermal contact with the light-transmitting component 200 for refrigerating the light-transmitting component 200;
[0057] A switching controller 500 is electrically connected with the light-emitting component 300 and the refrigeration component 400, and switches and adjusts the working mode of the skin care device between at least two working modes, at least one of which is for the light-emitting component 300 to work to care for the skin, and at least one of which is for the refrigeration component 400 to work while the light-emitting component 300 does not work to care for the skin.
[0058] In the embodiment, the skin care device includes the housing assembly 100, the light-transmitting component 200, the light-emitting component 300, the refrigeration component 400, and the switching controller 500, which cooperate with each other to achieve multifunctional skin care. The housing assembly 100 not only serves as a support structure of the device, but also provides a mounting base for other components, and is designed to be ergonomically shaped, such as streamlined, so as to be comfortable for the user to hold. The material of the housing assembly 100 can be selected from lightweight and durable plastics or metals to ensure the durability and feel of the device.
[0059] The light-transmitting component 200 is mounted at the light outlet 101a of the cosmetic head 101 of the housing assembly 100 and partially exposed from the housing to facilitate smooth irradiation of light onto the skin, wherein the light-transmitting component 200 can be made of transparent or translucent materials such as sapphire or glass, which have good optical conductivity and heat resistance.
[0060] The light-emitting component 300 is fixed inside the housing assembly 100 and emits light of a specific wavelength towards the light-transmitting component 200, which can be selected from light sources such as LEDs, laser diodes, halogen lamps, etc., and different wavelengths of light can be selected according to specific care needs. The refrigeration component 400 closely adheres to the light-transmitting component 200 and can be connected with the light-transmitting component 200 through a heat-conducting material such as heat-conducting glue or heat-conducting copper sheet to ensure that the light-transmitting component 200 can be cooled in real time when the light irradiates the skin to prevent it from overheating. As for the specific selection of the refrigeration component 400, a semiconductor refrigeration sheet or a miniature compressor refrigeration device can be used to achieve efficient temperature control.
[0061] As for the semiconductor cooling plate, also commonly known as Peltier cooling plate, it is an electronic cooling device based on semiconductor materials. Its working principle is based on the Peltier effect, that is, when direct current passes through the junction of two different materials of semiconductor, it will produce heat transfer effect. One side will absorb heat and become cold, while the other side will release heat and become hot. By continuously driving the current, the cold end can maintain a lower temperature, thus achieving the effect of cooling. Since the semiconductor cooling plate has no mechanical moving parts in its cooling process, it is very quiet and has no wear and tear during operation, with high reliability. Moreover, the semiconductor cooling plate is small in size and light in weight, suitable for integration in devices with limited space, especially handheld or portable devices.
[0062] The switching controller 500 is electrically connected to the light-emitting device 300 and the cooling element 400, and can adjust the working state of the device according to the mode selected by the user, so that the skin care device can flexibly switch between light care, current care and cold compress care, to meet different skin care needs. Specifically, the switching controller 500 can be implemented by using various types of control chips or integrated circuits (IC) in this embodiment. Common choices include microcontroller (MCU) chips such as STM32 series of STMicroelectronics or PIC series of Microchip, which can be flexibly controlled through programming to switch on and off and switch modes of the light-emitting device 300 and the cooling element 400. In addition, dedicated power management chips (PMIC) can also be used to handle power distribution and switching, such as TPS series of Texas Instruments or ADP series of Analog Devices, which can effectively manage multiple power sources and switch modes.
[0063] Further, the microcontroller (MCU) or other programmable chips used in the switching controller 500 can be programmed with preset mode programs. By pre-writing and programming different mode programs, the device can automatically switch between various functional modes, such as light care, current care, cold compress care or comprehensive care, etc. These mode programs can be customized according to user needs and selected and switched through the keys or other input methods in the switching controller 500, making the operation of the device more convenient and the function more rich.
[0064] In actual use, the user can select different care modes through the switching controller 500. For example, in the light care mode, the light emitting device 300 is turned on and irradiates light of a specific wavelength to the skin through the light transmitting member 200, and the light transmitting member 200 effectively conducts the light to achieve deep skin care. At the same time, the cooling member 400 works simultaneously, and through the heat conduction connection with the light transmitting member 200, the heat generated by the light transmitting member 200 is quickly absorbed and dissipated, thereby avoiding the overheating phenomenon caused by long-term irradiation of the light transmitting member 200, preventing the user's skin from being burned due to overheating of the device, and greatly improving the user's comfort when using the product.
[0065] When switching to the cold compress function mode, the switching controller 500 will turn off the light emitting device 300, and only keep the cooling member 400 working, and the temperature of the light transmitting member 200 is further reduced, and the device only cools the skin through the cooled light transmitting member 200. This function is particularly suitable for use after light care, which can quickly calm the skin and reduce the heat and discomfort after light. In addition, the user can also select the comprehensive care mode, in which the light emitting device 300 and the cooling member 400 work simultaneously, and the device provides light and micro-current care while continuously cooling the light transmitting member 200, ensuring the comfort and safety of long-term care. The flexible switching of multiple modes makes the skin care device not only have light and current care functions, but also can provide cold compress care, so that the user can use the single cold compress function to reduce the skin temperature, calm the skin, reduce the probability of skin allergy, improve the user's skin comfort, and greatly expand the application scene and use effect of the device.
[0066] In the technical scheme of the embodiment, the shell assembly 100 is partially formed with a beauty head 101 having a light outlet 101a for allowing light generated by the light emitting device 300 to be emitted through the light-transmitting piece 200 installed at the light outlet 101a. By arranging the cooling piece 400 inside the shell assembly 100 and making it in heat-conducting connection with the light-transmitting piece 200, and by arranging the switching controller 500 to switch and adjust the working mode of the skin care device between at least two working modes, at least one of which is for the light emitting device 300 to work to care for the skin, and at least one of which is for the cooling piece 400 to work while the light emitting device 300 does not work, so that the cooling piece 400 alone cools and cares for the skin. In use, the switching controller 500 can control the cooling piece 400 to absorb the heat of the light-transmitting piece 200 to lower its temperature, which can avoid the problem of overheating and burning the skin of the user due to long-time use, and improve the comfort of the user when using the product. At the same time, through the arrangement of the switching controller 500, the skin care device can be switched to the cooling function alone and to the light care function, so that the user can use the cooling function alone to lower the skin temperature, calm the skin, and reduce the probability of skin allergy, and improve the comfort of the user's skin during skin care.
[0067] In some embodiments, the switching controller 500 switches and adjusts the working mode of the skin care device between at least two working modes: in the first working mode, the switching controller 500 controls the light emitting device 300 to work and the cooling piece 400 to cool the light-transmitting piece 200; in the second working mode, the switching controller 500 controls the cooling piece 400 to cool the light-transmitting piece 200.
[0068] In the embodiment, the switching controller 500 of the skin care device is further optimized to more flexibly control the functions of the device in different working modes. Specifically, the switching controller 500 can be switched and adjusted between at least two working modes to meet the selection of the user in different skin care needs.
[0069] In the first working mode, the switching controller 500 activates the light emitting device 300 and the cooling piece 400 at the same time, so that the light emitting device 300 emits light of a specific wavelength to perform phototherapy on the skin through the light-transmitting piece 200. At the same time, the cooling piece 400 absorbs the heat generated by the light-transmitting piece 200 in real time through the heat-conducting connection with the light-transmitting piece 200, to ensure that the temperature of the light-transmitting piece 200 is maintained at a low level, thereby avoiding overheating. This mode of simultaneous phototherapy and cooling can provide effective light care while preventing discomfort of the skin due to long-time light exposure, thereby improving the overall care effect and user experience.
[0070] In the second working mode, the switching controller 500 turns off the light-emitting device 300 and only keeps the refrigerating device 400 working, so that the light-transmitting device 200 continues to maintain a low temperature. This mode is mainly used for providing pure cold compress care after light therapy, helping to calm the skin and relieve the skin heat and discomfort that may occur after light exposure. Through the continuous cooling of the refrigerating device 400, the risk of skin burns caused by long-term light exposure can be effectively avoided, further improving the safety of the device.
[0071] The present embodiment enables users to enjoy a more balanced and comfortable skin care experience during use by simultaneously activating the light therapy and cold compress functions in the first working mode. The second working mode focuses on the cold compress function and provides soothing care immediately after light therapy. Such a mode setting not only considers the efficient skin care effect, but also takes into account the comfort and safety of users. Through such mode switching, the skin care device can more flexibly adapt to different needs of users, increasing the functionality and use convenience of the device.
[0072] Referring to Figure 1 and Figure 4 In the present embodiment, the skin care device further includes a plurality of electrodes 103 distributed on the periphery of the light-transmitting device 200, and each electrode 103 is at least partially exposed to the cosmetic head 101. This can include a case where the electrode 103 protrudes from the cosmetic head 101, a case where the electrode 103 is flush with the surface of the cosmetic head 101, or a case where the electrode 103 is recessed from the surface of the cosmetic head 101 by a certain distance, for outputting microcurrent and / or radiofrequency current to the skin.
[0073] In the present embodiment, by introducing these electrodes 103, the device's functionality is greatly expanded, enabling it not only to perform light therapy and cold compress care, but also to implement current therapy on the same device.
[0074] Specifically, the output of microcurrent and / or radiofrequency current can effectively promote the metabolism of skin cells, help improve the firmness and elasticity of the skin, and to some extent, reduce wrinkles. Secondly, these currents can stimulate deep skin tissues and accelerate blood circulation, helping to improve skin color and overall skin condition. In addition, the combination of microcurrent from the electrodes 103 with light therapy and cold compress functions can provide more comprehensive skin care effects in different care modes.
[0075] In the embodiment, the switching controller 500 can incorporate the function of the electrode 103 into different working modes. For example, in the first working mode, the light-emitting device 300 and the cooling device 400 work simultaneously, while the electrode 103 outputs a micro-current and / or a radio frequency current to achieve the synchronization of light therapy and electrical therapy, further enhancing the treatment effect. In the second working mode, the light-emitting device 300 is turned off, and the cooling device 400 and the electrode 103 work simultaneously to provide combined care of cold compress and electrical therapy to achieve the dual effect of calming the skin and deep stimulation. In the switching process of these modes, the operation of the electrode 103 is coordinated with the light therapy and cold compress functions to achieve more comprehensive skin care.
[0076] As for the material selection of the electrode 103, materials with good electrical conductivity and no skin irritation can be selected, such as medical-grade stainless steel, titanium alloy, or silver-coated materials. These materials not only ensure the effective conduction of current, but also avoid skin allergic reactions during use. The arrangement of the electrode 103 takes into account the contact area and uniformity with the skin. Multiple electrodes 103 are symmetrically distributed around the light-transmitting member 200 to ensure uniform distribution of the micro-current or radio frequency current on the skin, avoiding poor treatment effect or skin discomfort caused by uneven current.
[0077] With the addition of the electrode 103, the skin care device in the embodiment not only provides diversified care modes, but also better meets the user's demand for comprehensive skin care effect, enhancing the practicality and market competitiveness of the device.
[0078] Further, in the first working mode, the switching controller 500 controls the light-emitting device 300 to work, the cooling device 400 to cool the light-transmitting member 200, and the electrode 103 to output a micro-current.
[0079] In the embodiment, the light-emitting device 300 emits light of a specific wavelength, which passes through the light-transmitting member 200 to perform light therapy on the skin. Light therapy stimulates skin cells, promotes blood circulation and collagen production, and helps improve skin quality and reduce fine lines. At the same time, the cooling device 400 is in thermal contact with the light-transmitting member 200, and continuously cools the light-transmitting member 200 through the cooling mechanism to ensure that the temperature of the light-transmitting member 200 does not become too high during light therapy, avoiding skin discomfort or burns caused by long-term use.
[0080] The addition of the electrode 103 makes the care process more comprehensive. In the first working mode, the electrode 103 is activated to output a micro-current to the skin. The micro-current can mimic the bio-current, gently stimulate the skin cells, promote cell metabolism, and accelerate skin repair. When used in combination with light therapy, the micro-current can also enhance the effect of light therapy, allowing the light to act on the skin more deeply and achieve more significant cosmetic effects. Through the synchronous action of micro-current and light therapy, the skin can be effectively repaired and regenerated under the stimulation of light, while experiencing the tightening and lifting effects brought by the micro-current.
[0081] The first working mode in this embodiment takes into account the synergistic effect of multiple care methods, fully utilizes the advantages of light therapy, micro-current, and cold compress, and provides a composite skin care solution. When using this mode, the user can not only obtain the dual benefits of light therapy and electrotherapy, but also effectively avoid heat accumulation caused by the device with the assistance of cold compress, improving the comfort and safety during use.
[0082] Further, in this embodiment, the switching controller 500 further includes a third working mode for controlling the operation of the light emitting device 300 and the micro-current output of the electrode 103 assembly;
[0083] In the first working mode, the switching control controls the micro-current intensity output by the electrode 103 to be less than the micro-current intensity output by the electrode 103 in the third working mode, and the switching controller 500 controls the light energy output by the light emitting device 300 in the first working mode to be greater than the light energy output by the light emitting device 300 in the third working mode.
[0084] In this embodiment, the switching controller 500 of the skin care device is provided with a third working mode to meet the diverse skin care needs of users. Specifically, the switching controller 500 can switch and adjust between the first, second, and third working modes to achieve different functional combinations and care effects.
[0085] In the third working mode, the switching controller 500 controls the light emitting device 300 and the electrode 103 assembly to work simultaneously, but the parameter settings are different from those in the first working mode. At this time, the micro-current intensity output by the electrode 103 assembly is higher than that in the first working mode, aiming to provide deeper skin stimulation and lifting effects. At the same time, the light energy output by the light emitting device 300 is lower than the output level in the first working mode, mainly serving as an auxiliary role to promote the effect of the micro-current while avoiding excessive light stimulation.
[0086] In such a configuration, the first working mode mainly focuses on the light therapy efficacy. The light emitting device 300 outputs light rays of specific wavelengths with high light energy, which irradiates the skin through the light transmitting piece 200, achieving effects such as whitening, fading spots, and promoting collagen production. The electrode 103 assembly outputs a lower intensity of micro-current in this mode, assisting the light therapy process, improving the overall effect of care, while the refrigeration piece 400 cools the light transmitting piece 200, ensuring comfort and safety during use.
[0087] Correspondingly, the third working mode focuses more on micro-current therapy. The electrode 103 assembly acts on the skin with a higher micro-current intensity, which can effectively stimulate muscles and deep tissues, achieving effects such as skin tightening, facial contour lifting, and fine line reduction. At this time, the light emitting device 300 outputs light rays with lower light energy, assisting the micro-current therapy, promoting the skin's response to micro-current, and improving the overall effect of care. In addition, the lower light energy output can also avoid excessive light exposure to the skin, which is suitable for users who are sensitive to light or specific care scenarios. The refrigeration piece 400 can be selectively operated in this mode to provide a comfortable cold compress effect, further enhancing the user experience.
[0088] By adjusting the working parameters of the light emitting device 300 and the electrode 103 assembly in different modes, the switching controller 500 can accurately control the functional output of the skin care device, meeting the diverse care needs of users at different times and in different skin conditions. For example, users can choose the first working mode for daily basic care, using high-energy light therapy for comprehensive skin maintenance; when they need to focus on improving skin firmness, they can choose the third working mode to fully utilize high-intensity micro-current for deep care.
[0089] In addition, the switching controller 500 can pre-burn programs of multiple working modes, and users can easily switch between modes through simple button or touch operations. Such a design improves the ease of use and intelligence level of the device, allowing users to flexibly choose the most suitable care solution according to their own needs, achieving the best skin care effect.
[0090] In some embodiments, the switching controller 500 switches and adjusts the working mode of the skin care device between at least three working modes: the switching controller 500 controls the electrode 103 to output micro-current and radio frequency current, the light emitting device 300 to emit light rays with wavelengths between 630nm and 1940nm, and the refrigeration piece 400 to cool the light transmitting piece 200; the switching controller 500 controls the electrode 103 to output micro-current, the light emitting device 300 to emit light rays with wavelengths between 630nm and 1940nm, and the refrigeration piece 400 to cool the light transmitting piece 200; the switching controller 500 controls the refrigeration piece 400 to work while the electrode 103 and the light emitting device 300 do not work.
[0091] In the first working mode of the embodiment, the switching controller 500 activates the electrode 103, the light-emitting device 300 and the refrigeration device 400 simultaneously. In this mode, the electrode 103 outputs micro-current and radio frequency current, which, in combination with the deep thermal effect of the radio frequency current and the cell stimulation effect of the micro-current, can significantly improve the firmness and elasticity of the skin. The light-emitting device 300 emits specific light with a wavelength in the range of 630 nm to 1940 nm, which is irradiated onto the skin through the light-transmitting member 200 to achieve a phototherapy effect, such as promoting collagen production, improving skin discoloration and dullness, etc. At the same time, the refrigeration device 400 cools the light-transmitting member 200 through the heat-conducting connection with the light-transmitting member 200, ensuring that the light-transmitting member 200 does not overheat during the operation of the light-emitting device 300, thereby improving the comfort of the user.
[0092] In the third working mode, the switching controller 500 controls the electrode 103 to output micro-current, and the light-emitting device 300 and the refrigeration device 400 are still working. This mode mainly uses the output of micro-current for relatively mild skin stimulation, which is suitable for daily basic care. Micro-current can promote the vitality of skin cells and enhance the absorption effect of skincare products at a higher current intensity, while the light-emitting device 300 still emits light with a wavelength between 630 nm and 1940 nm for auxiliary phototherapy to help improve skin texture and luster. The refrigeration device 400 continues to work to maintain the appropriate temperature of the light-transmitting member 200, preventing excessive heat accumulation in the skin due to phototherapy.
[0093] In the second working mode, the switching controller 500 only controls the refrigeration device 400 to work, and the electrode 103 and the light-emitting device 300 stop working. This mode focuses on cold compress care and is suitable for skin calming after phototherapy or electrotherapy. Through the continuous cooling of the light-transmitting member 200 by the refrigeration device 400, the skin heat and discomfort after phototherapy or current stimulation can be effectively alleviated, providing a comfortable cold compress experience. This mode is particularly suitable for users with sensitive skin or as a cooling and calming process after phototherapy and electrotherapy.
[0094] Through the combination of the three working modes, the skin care device can provide personalized care solutions in different use scenarios. For example, the user can choose the first working mode when deep care is needed, using the combined effect of radio frequency current, micro-current and phototherapy for intensive care; in daily care, the second working mode can be selected for mild care mainly using micro-current and phototherapy; when calming and cold compress are needed, the third working mode can be selected to enjoy the soothing effect of cold compress.
[0095] Further, the frequency of the radio frequency current in the first working mode is in the range of 0.8 MHz to 3.5 MHz.
[0096] In the first working mode in the embodiment, the switching controller 500 controls the electrode 103 to output a radio frequency current with a frequency range of 0.8-3.5 MHz. The radio frequency current can effectively stimulate the generation of collagen by generating a deep thermal effect in the skin, promote the repair and regeneration of skin cells, and help improve the firmness and elasticity of the skin.
[0097] The reason for adopting a frequency range of 0.8-3.5 MHz is that the radio frequency current at this frequency can penetrate the dermis of the skin and produce a mild and lasting thermal effect, which can not only tighten loose skin but also reduce fine lines and wrinkles and improve the overall texture of the skin. In addition, the radio frequency current at this frequency range is relatively mild on the skin and is less likely to cause discomfort, making it suitable for most skin types, thereby ensuring the user's comfort experience while achieving effective care.
[0098] Referring to Figure 2 and Figure 3 In the embodiment, the skin care device further comprises a mode adjustment device 104 that is at least partially exposed to the shell assembly 100 for an operator to manipulate to control the switching controller 500 to switch and adjust the working mode of the skin care device between at least three working modes. The mode adjustment device 104 is one of a key, a knob, a dial, or a touch screen.
[0099] In the embodiment, the skin care device further comprises a mode adjustment device 104. The mode adjustment device 104 is at least partially exposed to the outside of the shell assembly 100 for easy manipulation by the operator. Through the mode adjustment device 104, the user can easily control the switching controller 500 to switch and adjust the working mode of the skin care device between at least three working modes.
[0100] Specifically, the mode adjustment device 104 can be designed as one of a key, a knob, a dial, or a touch screen, providing a variety of operation methods according to different use scenarios and user habits. For example, the key design is simple and intuitive, suitable for quick mode switching; 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 of each mode, providing a more intelligent and interactive operation experience.
[0101] In the embodiment, the introduction of the mode adjustment device 104 improves the user-friendliness of the device, allowing the operator to easily and quickly switch the working mode of the device, whether between different modes such as phototherapy, electrotherapy, and cold compress. This design not only improves the operational convenience of the device but also enhances the user's experience.
[0102] Referring to Figure 2In the present embodiment, the skin care device further comprises mode indicator lights 105, which are arranged on the housing assembly 100 and close to the mode adjustment means 104, and are used to indicate the at least two working modes of the skin care device respectively.
[0103] In the present embodiment, the skin care device further comprises mode indicator lights 105, which are arranged on the housing assembly 100 and close to the mode adjustment means 104, and are used to indicate the at least two working modes of the skin care device respectively.
[0104] Specifically, the mode indicator lights 105 can be arranged in at least two ways:
[0105] 1. In the first arrangement, three different mode indicators are provided on the housing assembly 100, each corresponding to an independent mode indicator light 105. When the user switches to a certain mode through the mode adjustment means 104, the corresponding mode indicator light 105 will light up, clearly indicating the currently selected mode. This arrangement is intuitive and suitable for users who need to quickly identify and operate.
[0106] 2. In the second arrangement, the mode indicator lights 105 are represented by at least three different colors to represent different working modes. When the user switches modes, the color of the indicator light will change accordingly, for example, red for the first working mode, blue for the second working mode, and green for the third working mode. This colorful indication not only looks beautiful, but also provides clear mode indication in a small space.
[0107] As for the selection of mode indicator lights 105, LED lights can be chosen, which have high brightness, low energy consumption and long service life, and are very suitable for portable devices. LED lights can also achieve switching of multiple colors, further enhancing the user experience of the device.
[0108] Through this design, the skin care device in the present embodiment can effectively indicate the current working mode through the intuitive mode indicator lights 105 during use, making the user's operation more clear and accurate, thereby improving the ease of use and overall experience of the device.
[0109] Continuing to refer to Figure 2 and Figure 3In the present embodiment, the housing assembly 100 comprises a first end portion 100a, a second end portion 100b spaced apart from the first end portion 100a, and a peripheral portion 100c connected between the first end portion 100a and the second end portion 100b, and the first end portion 100a forms the cosmetic head 101;
[0110] The mode adjustment device 104 is arranged on the peripheral portion 100c of the housing assembly 100.
[0111] In the present embodiment, the housing assembly 100 of the skin care device comprises a first end portion 100a, a second end portion 100b spaced apart from the first end portion 100a, and a peripheral portion 100c connected between the first end portion 100a and the second end portion 100b. Among them, the first end portion 100a forms the cosmetic head 101 for directly contacting and caring for the skin.
[0112] The mode adjustment device 104 is arranged on the peripheral portion 100c of the housing assembly 100. This design places the mode adjustment device 104 in a position that is easy to reach by the user's fingers when holding the device, making it easy for the user to press and operate during use. By arranging the adjustment device on the peripheral portion 100c, the user can quickly switch the working mode of the device without changing the holding posture, greatly improving the operation convenience and user experience of the device.
[0113] This design takes into account ergonomics, allowing the device to maintain a compact design while providing intuitive and easy-to-access controls.
[0114] Continuing to refer to Figure 2 In the present embodiment, the skin care device further comprises a heat sink 401 and a heat pipe 402, the heat sink 401 is arranged in the housing assembly 100, one end of the heat pipe 402 of the heat sink 401 is arranged in the heat sink 401, and the other end is connected with the heating end of the refrigeration component.
[0115] In the present embodiment, the skin care device further comprises a heat sink 401 and a heat pipe 402 to improve the heat dissipation effect of the device and ensure the stability of the device and the comfort of the user during long-term use. Specifically, the refrigeration component 400 can use a semiconductor refrigeration sheet, which cools the light-transmitting component 200 through its cold end, and generates heat at its hot end, which needs to be dissipated through an effective heat dissipation system. That is, a heat sink 401 and a heat pipe 402 can be added, specifically, the heat sink 401 can be arranged inside the housing assembly 100, and a heat dissipation fin structure can be used to increase the heat dissipation area and improve the heat dissipation efficiency. To further improve the heat dissipation effect, a small heat dissipation fan can be installed around the heat sink 401, and the fan can accelerate the heat dissipation process of the fins through air flow, thereby more quickly dissipating the heat inside the device.
[0116] The heat dissipation pipe 402 can be designed with high thermal conductivity copper pipe, similar to the heat dissipation copper pipe commonly used in notebook computers. One end of the copper pipe is connected to the heat sink 401, and the other end is in thermal contact with the heat generating end of the semiconductor refrigeration piece. The copper pipe has good thermal conductivity and can quickly conduct the heat generated by the heat generating end of the refrigeration piece 400 to the heat sink 401, thereby avoiding the accumulation of heat inside the device.
[0117] To further increase the heat conduction efficiency, thermal conductive silicone grease can be added between the copper pipe and the heat generating end of the refrigeration piece 400. The thermal conductive silicone grease can fill the small gaps between the copper pipe and the heat generating end of the refrigeration piece 400, ensuring that the heat is more effectively conducted to the copper pipe and quickly dissipated through the heat sink 401 and the fan. This design not only effectively reduces the operating temperature of the refrigeration piece 400, but also prolongs the service life of the device and improves the user's comfort during use.
[0118] The embodiment adds a comprehensive heat dissipation design of the heat sink 401, the heat dissipation pipe 402 and the thermal conductive silicone grease, so that the skin care device can maintain low temperature operation while efficiently cooling, avoiding the influence of heat accumulation on the performance of the device or causing discomfort to the user. The optimization design of this heat dissipation system enables the device to maintain stable and efficient working state even after long time use.
[0119] Referring to Figures 5 to 9 , Figure 5 is a side view of the skin care device in an embodiment of the present application, Figure 6 is Figure 5 a cross-sectional view of the position C-C in the embodiment, Figure 7 is Figure 6 a local enlarged view of the position D in the embodiment, Figure 8 is a structural schematic view of the beauty head in an embodiment of the present application, Figure 9 is Figure 8 a cross-sectional view of the position E-E in the embodiment.
[0120] In the embodiment, the light-transmitting piece 200 includes a first end surface 201 facing the light-emitting device 300 and a second end surface 202 opposite to the first end surface 201 and exposed outside the beauty head 101, the first end surface 201 includes a light-transmitting region and a non-light-transmitting region, and the non-light-transmitting region is located at the periphery of the light-transmitting region.
[0121] The number of refrigeration pieces 400 is at least two, and the at least two refrigeration pieces 400 are distributed along the circumference of the light-transmitting piece 200 and are respectively in thermal contact with the non-light-transmitting region.
[0122] In the present embodiment, the light-transmitting piece 200 includes a first end surface 201 arranged to face the light-emitting device 300 and a second end surface 202 opposite to the first end surface 201 and exposed outside the cosmetic head 101. The first end surface 201 is further divided into a light-transmitting region and a non-light-transmitting region, wherein the light-transmitting region is used for the light emitted by the light-emitting device 300 to pass through smoothly, and the non-light-transmitting region is located at the periphery of the light-transmitting region and is used for functional connection with other components (specifically, providing a mounting area for the refrigeration piece 400).
[0123] In the present embodiment, the number of refrigeration pieces 400 is at least two, and they are spaced along the circumference of the light-transmitting piece 200. Each refrigeration piece 400 is in thermal connection with the non-light-transmitting region of the light-transmitting piece 200. By arranging the refrigeration piece 400 in the non-light-transmitting region, it is ensured that the light emitted by the light-emitting device 300 will not be blocked, thereby not affecting the phototherapy effect. At the same time, the arrangement of multiple refrigeration pieces 400 (for example, two or more) can improve the refrigeration efficiency and ensure that the light-transmitting piece 200 remains in a suitable low-temperature state during a long period of work, preventing discomfort caused by overheating.
[0124] In order to further improve the refrigeration effect, a heat-conducting material such as heat-conducting silicone grease, heat-conducting gasket or heat-conducting glue can be added between the refrigeration piece 400 and the non-light-transmitting region of the light-transmitting piece 200. These heat-conducting materials can fill the gap between the refrigeration piece 400 and the light-transmitting piece 200, enhance the heat conduction efficiency, make the refrigeration effect more significant, and thus improve the stability of the device during use and the user experience.
[0125] Continuing to refer to Figure 8 and Figure 9 In the present embodiment, the outer edge of the second end surface 202 is a polygon with more than four sides;
[0126] and / or, the light-transmitting piece 200 is sapphire.
[0127] The light-transmitting piece 200 in the present embodiment, through such a polygonal design, more electrodes 103 can be arranged around the second end surface 202, which has a significant advantage especially when interlaced current processing is needed.
[0128] Specifically, when the second end surface 202 is a polygon (such as a pentagon, a hexagon or a polygon with more sides), the device can arrange one or more electrodes 103 at the corresponding position of each side. The increase in the number of electrodes 103 not only increases the current coverage area of the device during skin care, but also makes the density of the interlaced current higher and the distribution of the current on the skin more uniform and fine. Such a design can improve the effect of current stimulation, improve the tightness and elasticity of the skin, and enhance the overall effect of care.
[0129] In addition, in the present embodiment, the light-transmitting member 200 can be made of sapphire material. Sapphire has extremely high hardness and excellent optical transmittance, and can well withstand long-term light exposure and current output of the device, ensuring the service life and stability of the device. The combination of the sapphire light-transmitting member 200 and the polygonal second end face not only makes the device more unique in appearance, but also has stronger functionality and durability. Through such a polygonal design and material selection, the skin care device in the present embodiment is improved in both current interlacing density and optical performance, further optimizing the user's experience and care effect.
[0130] With reference to Figure 4 In the present embodiment, the light-emitting device 300 includes at least one halogen lamp;
[0131] The skin care device further includes a filter 106, which is arranged in the housing assembly 100 and located between the halogen lamp and the light-transmitting member 200.
[0132] In the present embodiment, the light-emitting device 300 specifically selects at least one halogen lamp. Halogen lamps have high light output efficiency and stable spectral output, and the wavelengths of the light emitted by halogen lamps can be adjusted within the range of 630nm to 1940nm, which is suitable for various skin care applications such as promoting collagen production, improving skin color and texture, etc.
[0133] In order to optimize the quality and effect of light, the skin care device further includes a filter 106, which is arranged in the housing assembly 100 and located between the halogen lamp and the light-transmitting member 200. The main function of the filter 106 is to filter out unnecessary spectral components emitted by the halogen lamp, especially short-wavelength ultraviolet or visible light that may cause irritation or discomfort to the skin, so as to allow only light within a specific wavelength range to pass through. This not only improves the effect of phototherapy, but also reduces potential damage to the skin.
[0134] Specifically, the filter 106 can ensure that the transmitted light is concentrated within the most beneficial wavelength range, such as between 630nm and 1940nm. Such light can more effectively penetrate the skin and reach the deep tissues, activating the regeneration and repair of skin cells. At the same time, the filter 106 can also prevent heat accumulation due to unnecessary light scattering, thereby protecting the light-transmitting member 200 and other components from overheating and prolonging the service life of the device.
[0135] By using halogen lamps as the light-emitting device 300 and combining the use of the filter 106, the skin care device in the present embodiment can provide more precise and efficient phototherapy services, ensuring the quality of the light and improving the safety and stability of the device.
[0136] With reference to Figure 6 andFigure 7 , Figure 6 is Figure 5 a cross-sectional view of the skin care device at C-C, Figure 7 is Figure 6 a close-up view of the skin care device at D.
[0137] In this embodiment, the skin care device further comprises an auxiliary light strip 107, which is disposed on the side of the filter 106 opposite the light emitting device 300. The auxiliary light strip 107 comprises green LED lights, which are electrically connected to the switching controller 500. The switching controller 500 controls the green LED lights to work when the cooling element 400 is working.
[0138] Alternatively, the auxiliary light strip 107 comprises blue LED lights, which are electrically connected to the switching controller 500. The switching controller 500 controls the blue LED lights to work when the cooling element 400 is working.
[0139] In this embodiment, the skin care device further comprises an auxiliary light strip 107, which is disposed on the side of the filter 106 opposite the light emitting device 300. The auxiliary light strip 107 comprises green LED lights, which are electrically connected to the switching controller 500. The switching controller 500 controls the green LED lights to work when the cooling element 400 is working.
[0140] In the first embodiment, the auxiliary light strip 107 is composed of green LED lights, which are electrically connected to the switching controller 500. When the switching controller 500 controls the cooling element 400 to work, the green LED lights also work at the same time. The cooling element 400 cools the skin through the light-transmitting element 200, while the green light emitted by the green LED lights irradiates on the skin.
[0141] For example, the wavelength of green light is usually between 500nm and 570nm, which has the effects of calming, soothing and anti-inflammatory. Combined with the cooling function, the green LED light can further help to reduce the swelling and soothe the irritation of the skin, and is particularly suitable for the care of sensitive skin. The combination of green light and cooling can reduce the temperature of the skin, reduce the inflammatory response, and make the skin feel more comfortable and relaxed.
[0142] In addition to using LED lights, the auxiliary light strip can also choose OLED lights, cold cathode fluorescent lamps (CCFL) or organic light-emitting diodes (OLED) and other light sources that can emit green light. These light sources can also provide stable green light effects, and may be more energy-efficient or have different light-emitting characteristics in some designs.
[0143] In another embodiment, the auxiliary light strip 107 is composed of blue LED lights, which are also electrically connected to the switching controller 500. In this mode, the blue LED lights are activated when the cooling element 400 is working. The cooling element 400 continues to provide the cold compress effect to the light-transmitting element 200, while the blue light emitted by the blue LED lights is irradiated onto the skin.
[0144] For example, the wavelength of blue light is usually between 450nm and 495nm, which has the effects of antibiosis, oil control and pore shrinking. Blue light can penetrate the skin surface, helping to improve sebum secretion, reduce acne and other skin inflammation problems. Combined with the cold compress function, the use of blue light can inhibit skin inflammation while providing additional calming effects, helping to tighten pores and brighten skin color.
[0145] In addition to LED lights, the auxiliary light strip can also use laser diodes, phosphor-coated light tubes, and other light sources that can emit blue light. These light sources can provide different intensities and effects of blue light irradiation according to specific device design and user needs.
[0146] Continuing to refer to Figure 6 In this embodiment, the skin care device further includes a ring-shaped reflector 108, which is arranged between the auxiliary light strip 107 and the light-transmitting element 200. The ring-shaped reflector 108 encloses a hollow inner hole, which is used for the light emitted by the auxiliary light strip 107 and the light emitted by the light-emitting device 300 to irradiate through and irradiate to the light-transmitting element 200.
[0147] In this embodiment, the skin care device further includes a ring-shaped reflector 108. The ring-shaped reflector 108 is arranged between the auxiliary light strip 107 and the light-transmitting element 200 and is designed to enclose a hollow inner hole. The hollow inner hole is used for the light emitted by the auxiliary light strip 107 and the light emitted by the light-emitting device 300 (such as a halogen lamp) to pass through and finally irradiate to the light-transmitting element 200, thereby improving the light transmission effect of the device.
[0148] The main function of the ring-shaped reflector 108 is to reduce the phenomenon of light absorption by the plastic shell inside the device. Under normal circumstances, the plastic shell may absorb part of the light, resulting in light loss. The ring-shaped reflector 108 can effectively reflect the emitted light back to the light-transmitting element 200 through its reflection characteristics, ensuring that the light from the halogen lamp and the LED light strip is better transmitted into the sapphire light-transmitting element 200, thereby significantly reducing light loss and improving light utilization efficiency.
[0149] The reflecting surface of the annular light-reflecting cover 108 can be processed into a mirror surface according to requirements to obtain higher reflectivity; or the surface thereof can be coated with a light-reflecting material, such as an aluminum plating layer, a silver coating layer or other high-reflectivity coating, to further enhance the light-reflecting effect. Through these measures, the annular light-reflecting cover 108 can maximize the retention of the light emitted by the light-emitting device 300 and the auxiliary illuminating lamp strip 107, and ensure that the energy of the light is fully utilized.
[0150] As for the material selection of the annular light-reflecting cover 108, metal materials such as aluminum or stainless steel can be used, which not only have good reflecting performance, but also have durability and heat dissipation performance. Alternatively, the annular light-reflecting cover 108 can also be made of high-reflectivity plastic materials, which can reduce the weight of the overall device while ensuring the light-reflecting effect.
[0151] By introducing the annular light-reflecting cover 108, the embodiment effectively reduces light loss, ensures that the light emitted by the halogen lamp and the LED lamp strip can maximize the transmission through the sapphire light-transmitting piece 200, and achieves better phototherapy effect. This design not only improves the light efficiency of the device, but also improves the user experience, making the effect of light care and cold compress more significant.
[0152] Continue to refer to 7 and Figure 8 、 Figure 9 In the embodiment, the light-transmitting piece 200 includes a first end surface 201 facing the light-emitting device 300 and a second end surface 202 opposite to the first end surface 201 and exposed outside the beauty head 101.
[0153] The skin care device further includes a light-transmitting sealing piece 109 arranged at the end of the light-reflecting cover away from the light-emitting device, and a closed cavity 203 is formed between the light-transmitting sealing piece 109 and at least a part of the first end surface.
[0154] In the embodiment, taking the sapphire as the light-transmitting piece 200, it has two main surfaces: one surface facing the light source is a hot surface (the first end surface 201), and the other surface contacting the user's skin is a cold surface (the second end surface 202). The hot surface of the sapphire faces the light-emitting device (such as the light source), and during the operation of the device, this surface is used to receive the high-intensity light emitted by the light source. Due to the continuous contact with the light source, the hot surface absorbs a certain amount of heat, and thus has a higher temperature.
[0155] The main reason for fogging is mainly that in a high-humidity environment, when the hot surface contacts the air outside, the temperature difference can cause the moisture in the air to condense on the hot surface to form fog, affecting the light-transmitting property of the light-transmitting piece 200 and the overall performance of the device. In order to prevent the hot surface of the sapphire from causing fogging due to temperature difference, the light-transmitting sealing piece 109 is used in the embodiment to prevent the fogging phenomenon.
[0156] Specifically, the light-transmitting sealing member 109 and the at least partially first end surface 201 form a closed cavity 203, that is, the light-transmitting sealing member 109 separates the hot surface of the sapphire from the external humidity, avoiding direct contact of the moisture with the hot surface. When the light-emitting device 300 emits light, the light-transmitting sealing member 109 ensures that the hot surface of the sapphire remains dry, thus effectively preventing the occurrence of fogging and maintaining the stable output and efficient transmission of light.
[0157] Further, the light-transmitting sealing member 109 can include a sealing ring and white glass. The inner ring of the sealing ring is provided with an annular groove in the circumferential direction for assembling the white glass. The assembled light-transmitting sealing member 109 is installed at the end of the reflector 108 away from the light-emitting device 300, and the sealing ring is provided with a protrusion at the end towards the light-transmitting member 200, which separates the white glass and the sapphire light-transmitting member 200, avoiding direct contact between them. In this way, the hot surface of the sapphire is completely isolated from the external air, avoiding the contact of the condensed moisture with the hot surface due to temperature difference. In addition, the air in the light-transmitting sealing member 109 does not flow, further reducing the influence of humidity change on the hot surface.
[0158] In this embodiment, white glass is selected as the material of the light-transmitting sealing member 109 because it has excellent high-temperature resistance and light-transmitting performance, and compared with acrylic material, white glass performs more stably in high-temperature environment. Of course, other materials with similar performance can also be selected, such as quartz glass or high-temperature resistant ceramic, which also have excellent light-transmitting performance and heat resistance.
[0159] In order to further improve the effect of preventing fogging, the inside of the light-transmitting sealing member 109 can be subjected to vacuumizing treatment. By vacuumizing, the air content in the light-transmitting sealing member 109 can be effectively reduced, thereby reducing the humidity and further preventing the sapphire hot surface from causing fogging due to temperature difference.
[0160] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
