[0055] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings.

[0056] Specific embodiments of the present application

[0057] The embodiments of the present application will be described below in detail with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0058] In the present application, the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implying the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that the technical solutions can be realized by those skilled in the art. When the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0059] Milk light is a specific wavelength of light energy that is transmitted to the deep layers of the skin through a light guide such as sapphire. After the light energy is absorbed by the skin, it is converted into heat energy, heating the skin surface and deep tissue, promoting blood circulation and cell metabolism, stimulating the generation of collagen and elastic fibers, thereby enhancing the skin's luster, tightness and elasticity.

[0060] Micro-current and radio frequency current apply weak current or high frequency electromagnetic waves to the skin through electrodes. These currents can produce a mild heat effect in the skin, promoting deep tissue heating. Radio frequency current can penetrate the skin surface directly to the dermis, heating collagen fibers and subcutaneous tissue, further promoting collagen contraction and regeneration, and improving skin tightness.

[0061] Although heat treatment can effectively improve the skin condition, it can also cause the skin temperature to rise, resulting in pore expansion, skin redness or discomfort. Cold compress plays an important role in this process, as it can help shrink pores, prevent impurities from entering the skin, and reduce skin inflammation. At the same time, cold compress can quickly reduce skin temperature, calm the skin and relieve discomfort caused by heat effect, further improving the comfort and overall effect of skin care. By alternating heat treatment and cold compress, the skin can better absorb care ingredients while reducing irritation and sensitivity, thereby achieving a healthier and balanced skin care effect.

[0062] In related art, skin care devices usually use a mode of cold compress while light irradiation. However, this approach has a cold compress temperature that is not low enough, and the cooling speed is not fast enough to quickly reduce the skin temperature, and cannot effectively offset the heat brought by light irradiation. That is, the bundled use of cold compress and light irradiation in related art limits the independent application of cold compress function, and cannot be used flexibly in scenarios where the skin needs to be cooled alone.

[0063] The present application proposes a separate cold compress mode, by setting an independent working mode, only activating the refrigeration component to cool the skin. Compared with the simultaneous cold compress of the prior art, the separate cold compress mode of the present application can provide a lower cold compress temperature and a faster cooling speed, which can quickly reduce the skin temperature to a comfortable range, thereby improving the comfort of the user. This independent cold compress mode not only effectively offsets the heat brought by light irradiation, but can also be widely used in other scenarios such as skin sensitive period, after-sun repair, etc. In these scenarios, the skin may become more fragile or sensitive due to external stimuli, at which time the separate cold compress can quickly calm the skin, reduce inflammation, shrink pores and reduce redness.

[0064] Specifically, refer to FIG. 1 to FIG. 4, FIG. 1 is a side view of a skin care device in an embodiment of the present application, FIG. 2 is a sectional view of A-A in FIG. 1, FIG. 3 is a partial enlarged view of B in FIG. 2, and FIG. 4 is a structural schematic view of the skin care device in an embodiment of the present application.

[0065] An embodiment of the present application provides a skin care device 10, which comprises:

[0066] A light emitting device 100, which is used for emitting light to irradiate and care skin;

[0067] A light transmitting member 200, which is used for transmitting the light emitted by the light emitting device 100 to irradiate and care skin;

[0068] A refrigeration member 300, which is in thermal contact with the light transmitting member 200 and is used for cooling the light transmitting member 200 to cool skin;

[0069] A controller 400, which is electrically connected with the light emitting device 100 and the refrigeration member 300 respectively, and is used for controlling the light emitting device 100 and the refrigeration member 300 to work;

[0070] The skin care device 10 is configured with a first working mode and a second working mode.

[0071] In the first working mode, the controller 400 is configured to control the light emitting device 100 to emit light towards the light transmitting member 200.

[0072] In the second working mode, the controller 400 is configured to control the refrigeration member 300 to refrigerate the light transmitting member 200, and make the light emitting device 100 in a state of stopping working.

[0073] In the embodiment of the present application, the light emitting device 100 can be selected from light sources such as LED, laser diode, halogen lamp, etc., and different wavelengths of light can be selected according to specific care requirements. The refrigeration member 300 is closely attached to the light transmitting member 200, and can be connected with the light transmitting member 200 through a heat conducting material such as heat conducting glue or heat conducting copper sheet, so as to ensure that the light transmitting member 200 can be cooled in real time when the light irradiates skin, and prevent it from overheating. As for the specific selection of the refrigeration member 300, a semiconductor refrigeration sheet or a micro compressor refrigeration device can be adopted to realize efficient temperature control.

[0074] As for the semiconductor cooling plate, also commonly known as Peltier cooling plate, is an electronic cooling device based on semiconductor materials. Its working principle is based on the Peltier effect, that is, when a direct current passes through the junction of two different materials of semiconductor, a heat transfer effect will be produced. 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, thereby 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, and has high reliability. Moreover, the semiconductor cooling plate is small in size and light in weight, and is suitable for integration in devices with limited space, especially handheld devices or portable devices.

[0075] The controller 400 in the embodiments of the present application is mainly used to control the working of the light emitting device 100 and the cooling device 300, which can be implemented by using various types of control chips or integrated circuits (IC). Common choices include microcontroller 400 (MCU) chips, such as the STM series of STMicroelectronics or the PIC series of Microchip, which can be flexibly controlled by programming to switch on and off and switch modes of the light emitting device 100 and the cooling device 300. In addition, dedicated power management chips (PMIC) can also be used to handle the distribution and switching of power, such as the TPS series of Texas Instruments or the ADP series of Analog Devices, which can effectively control the working of the light emitting device 100 and the cooling device 300; and the control program can be pre-burned in the control to automatically switch the working state of the light emitting device 100 and the cooling device 300. The program can be automatically executed or used to respond to the switching selection operation of the user.

[0076] The skin care device 10 in the embodiments of the present application is configured to have at least two working modes during use, one of which, i.e., the first working mode, the controller 400 controls the light emitting device 100 to work to perform heat care on the target skin area of the user, and the second working mode is to perform cold compress on the skin area after heat care; Specifically, the skin care device 10 realizes seamless switching of heat care and cold compress through the configuration of the two working modes. First, the user turns on the device to the first working mode, at which time the controller 400 activates the light emitting device 100, and the light emitting device 100 emits light, which is transmitted to the skin surface and deep layer through the light-transmitting piece 200 (such as sapphire) for light care. After the light energy is absorbed by the skin, it is converted into heat energy, which promotes skin metabolism and collagen production, thereby improving the luster, tightness and elasticity of the skin.

[0077] After the heat treatment is completed, the user can switch to the second working mode through the control interface or buttons of the device (of course, the controller 400 can also automatically switch internally according to the program). In the second working mode, the controller 400 stops the work of the light emitting device 100, and at the same time activates the refrigeration device 300. The refrigeration device 300 rapidly reduces the temperature of the light-transmitting device 200 through the heat-conducting connection with the light-transmitting device 200, and transmits its cooling effect to the skin to perform cold compress treatment. This cold compress can help shrink pores, calm the skin, and relieve the temperature rise and discomfort caused by heat treatment, achieving a more comprehensive skin care effect.

[0078] Of course, the user can also switch to the second working mode for cold compress treatment according to needs. For example, when the skin is red and swollen and hot due to long-term exposure to sunlight or environmental stimulation, the user may not need to perform heat treatment first, but directly need cold compress to quickly calm and soothe the skin. At this time, the user can directly select the second working mode, and the controller 400 will activate the refrigeration device 300 to cool the light-transmitting device 200 and transmit the cold compress effect to the skin surface, effectively shrink pores and relieve skin inflammation and discomfort. This separate cold compress function provides the user with flexible use options and can perform personalized care according to the actual state and needs of the skin.

[0079] In the technical scheme of the embodiment of the present application, through the light emitting device 100, the light-transmitting device 200, the refrigeration device 300 and the controller 400, integrated operation of heat treatment and cold compress is realized. Compared with the related art, in the first working mode, the controller 400 controls the light emitting device 100 to output light for heat treatment, and after the heat treatment is completed, the controller 400 can switch to the second working mode to control the refrigeration device 300 to perform cold compress treatment on the skin area after heat treatment, to help shrink pores, calm the skin, and relieve the temperature rise and discomfort caused by heat treatment.

[0080] In addition, the cumbersome steps of using an additional cold compress device in the related art are avoided, which not only reduces the operation complexity of the user, but also improves the continuity and efficiency of the care process. The user can complete the complete care process from heat treatment to cold compress in one device.

[0081] In some embodiments, in the first working mode, the controller 400 is further configured to control the refrigeration device 300 to refrigerate the light-transmitting device 200.

[0082] In the embodiments of the present application, the first working mode of the skin care device 10 not only controls the light emitting device 100 to emit light through the light-transmitting piece 200 to perform light irradiation care on the skin, but also configures the working of the refrigeration piece 300. Specifically, when the device is in the first working mode, the controller 400 is configured to synchronously control the operation of the light emitting device 100 and the refrigeration piece 300. The light generated by the light emitting device 100 transmits through the light-transmitting piece 200 to perform thermal care on the skin, which causes the temperature of the light-transmitting piece 200 (such as sapphire) to increase. In order to prevent the user from being uncomfortable or even scalded due to the excessively high temperature of the light-transmitting piece 200, the refrigeration piece 300 performs cooling on the light-transmitting piece 200 in this mode.

[0083] In the first working mode, the refrigeration capacity of the refrigeration piece 300 is dynamically adjustable. The refrigeration piece 300 automatically adjusts its refrigeration output according to the temperature change of the light-transmitting piece 200: when the temperature of the light-transmitting piece 200 increases, the refrigeration capacity of the refrigeration piece 300 also increases to ensure that the temperature of the light-transmitting piece 200 always remains within the range comfortable for the user. This dynamic adjustment mechanism can accurately control the temperature of the light-transmitting piece 200, avoiding the risk of overheating caused by long-term irradiation, thereby improving the safety of the device and the use comfort of the user.

[0084] In addition, the adjustment of the refrigeration capacity of the refrigeration piece 300 can also be controlled according to the preset care program. According to different care needs and program settings, the refrigeration capacity of the refrigeration piece 300 can be gradually increased or decreased during the care process to better match each care stage. For example, in the initial care stage, the refrigeration capacity of the refrigeration piece 300 can be low, and the refrigeration capacity is gradually increased as the care progresses, to balance the heat generated by the light-transmitting piece 200. This design not only enhances the flexibility and individualization of the device, but also enables the user to enjoy a safer and more comfortable care experience during use. Through the coordinated control of the light emitting device 100 and the refrigeration piece 300, the skin care device 10 of the embodiments of the present application effectively integrates the functions of thermal care and cold compress, providing a more comprehensive skin care solution for the user.

[0085] Continuing to refer to FIG. 3, in some embodiments, the skin care device 10 further includes an electrode assembly 501 for outputting microcurrent and / or radiofrequency current to the skin.

[0086] The addition of the electrode assembly 501 enables the device to combine microcurrent and radiofrequency current with light irradiation care to perform multiple care on the skin, thereby achieving a synergistic effect.

[0087] Specifically, in the first working mode, the controller 400 is further configured to control the working mode of the refrigeration piece 300 for refrigerating the light-transmitting piece 200 and the electrode assembly 501 for outputting microcurrent and / or radiofrequency current.

[0088] In the first working mode, the light energy (e.g., milk light) emitted by the light-emitting device 100 is transmitted to the skin through the light-transmitting member 200, mainly acting on the skin surface and deep tissue, promoting the metabolism of skin cells and the generation of collagen, effectively improving the glossiness, tightness and elasticity of the skin. The light energy can gently heat the skin, enhance blood circulation and improve the overall health of the skin.

[0089] At the same time, the micro-current output by the electrode assembly 501 is transmitted to the skin surface through the electrodes, simulating the body's bioelectricity, stimulating facial muscles and skin cells, promoting cell activity, and enhancing muscle tightness and skin elasticity. Micro-current can also accelerate the skin repair process, reduce fine lines and wrinkles, and make the skin look tighter and smoother.

[0090] The radio frequency current penetrates the dermis layer of the skin through the electrode assembly 501, producing a deep heating effect. The radio frequency current can heat the collagen fibers in the dermis layer, causing the collagen fibers to shrink and stimulate the production of new collagen. This deep heating effect not only helps to improve the tightness of the skin, but also improves the relaxation and wrinkles of the skin, with a deep anti-aging effect.

[0091] By combining light energy, micro-current and / or radio frequency current, the skin care device 10 in the embodiment of the present application achieves a synergistic care effect. Light energy provides mild heating and metabolic promotion on the surface layer, micro-current enhances the activity of cells and muscles, and radio frequency current improves the structure of collagen fibers in the dermis layer. This multi-level care method enables the skin to be comprehensively cared for and improved at different depths and levels, not only improving the efficiency and effect of care, but also providing users with a more comprehensive and comprehensive skincare experience.

[0092] In summary, the skin care device 10 is configured to switch between at least three working modes:

[0093] In the first working mode, the electrode assembly 501 outputs micro-current and radio frequency current, the light emitted by the light-emitting device 100, and the cooling member 300 cools the light-transmitting member 200;

[0094] In the second working mode, the cooling member 300 cools the light-transmitting member 200;

[0095] In the third working mode, the electrode outputs micro-current, the light-emitting device 100 emits light, and the cooling member 300 cools the light-transmitting member 200.

[0096] Specifically, in the first working mode, the device activates the electrode assembly 501, the light-emitting device 100 and the refrigeration piece 300 simultaneously. The electrode assembly 501 outputs micro-current and radio frequency current, which are transmitted to the skin through the electrodes, promoting cell activity and collagen production, and improving the firmness and elasticity of the skin. At the same time, the light-emitting device 100 emits light through the light-transmitting piece 200 to irradiate the skin, further enhancing the effect of phototherapy. However, since the light of the light-emitting device 100 can cause the temperature of the light-transmitting piece 200 to rise, in order to prevent the temperature of the light-transmitting piece 200 from being too high and possibly causing burns to the user's skin, the refrigeration piece 300 cools the light-transmitting piece 200 in this mode. The refrigeration amount of the refrigeration piece 300 is dynamically adjustable, automatically adjusted according to the real-time temperature change of the light-transmitting piece 200, to ensure that the temperature of the light-transmitting piece 200 always remains within the range comfortable for the user. This synergistic effect ensures that while the skin is being treated, the temperature of the light-transmitting piece 200 is effectively controlled, enhancing the safety and comfort of the treatment.

[0097] In the second working mode, the device only activates the refrigeration piece 300 to cool the light-transmitting piece 200 alone. This mode of cold compress treatment is mainly used after heat treatment or when the skin needs to be cooled and calmed quickly. Through direct cold compress, the refrigeration piece 300 rapidly reduces the temperature of the light-transmitting piece 200 and transmits the cooling effect to the skin, helping to shrink pores, calm the skin and relieve the temperature rise and discomfort caused by heat treatment. The single cold compress function of this mode provides users with flexible options to quickly perform cooling treatment when needed.

[0098] It should be noted that in the second working mode, the refrigeration piece 300 is working and the light-emitting device 100 is in a state of stopping working, which can be that the refrigeration piece 300 is controlled to work to cool the light-transmitting piece 200 (at this time the electrode assembly 501 can work) and the light-emitting device 100 is in a state of stopping working; in addition, preferably, neither the light-emitting device 100 nor the electrode assembly 501 works, only the refrigeration piece 300 works.

[0099] In the third working mode, the device activates the electrode assembly 501 and the light-emitting device 100, and at the same time the refrigeration piece 300 cools the light-transmitting piece 200. In this mode, the electrode assembly 501 outputs micro-current, which enhances cell activity through gentle stimulation of the skin; the light-emitting device 100 emits light for light therapy, which improves the luster and elasticity of the skin; and the refrigeration piece 300 cools the light-transmitting piece 200 simultaneously to avoid the temperature of the light-transmitting piece 200 being too high to affect the treatment experience. This mode combines the comprehensive treatment effects of phototherapy and micro-current, and at the same time ensures safety during use through the cooling effect of the refrigeration piece 300.

[0100] The three working modes can be executed in sequence according to a preset program to realize a complete hot care and cold compress process, or can be executed in any order to flexibly meet different care needs. Users can also select a suitable working mode according to individual needs and skin conditions, thereby enjoying personalized care experience. Through such multi-mode configuration, the device provides more abundant and efficient skin care solutions, ensuring that users can obtain the best care effect in each mode.

[0101] Further, the micro-current intensity output by the electrode assembly 501 in the first working mode is less than the micro-current intensity output by the electrode assembly 501 in the third working mode.

[0102] And / or, the light energy output by the light emitting device 100 in the first working mode is greater than the light energy output by the light emitting device 100 in the third working mode.

[0103] In the first working mode, the micro-current intensity output by the electrode assembly 501 is less than the micro-current intensity in the third working mode, because the main goal of the first working mode is to activate the epidermis of the cosmetic area and promote the generation of collagen, thereby improving the luster and elasticity of the skin. In this working mode, the light emitting device 100 plays an important role, so the light energy output by the light emitting device 100 is greater than that in the third working mode.

[0104] In the third working mode, the micro-current intensity output by the electrode assembly 501 is greater than the micro-current intensity output by the electrode assembly 501 in the first working mode, mainly using the micro-current to push and stimulate the epidermis of the cosmetic area to achieve the effect of tightening and fullness of the skin. This mode focuses on the deep effect of micro-current to improve the firmness of the skin, while the light emitting device 100 outputs lower light energy in this mode, and combines with the cold compress effect of the refrigeration piece 300 to provide cold therapy care for the skin. Through such comprehensive effect, the third working mode can enhance the tightening effect of the skin during the care process, and at the same time give the skin sufficient relief and sedation.

[0105] In some embodiments, in the first working mode, the controller 400 is further configured to control the electrode to output a radio frequency current, wherein:

[0106] The electrode assembly 501 outputs a radio frequency current with a frequency between 0.8MHz and 3.5MHz;

[0107] And / or, the electrode assembly 501 outputs a radio frequency current to heat the skin to a target temperature, and the target temperature is greater than or equal to 41℃ and less than or equal to 43℃.

[0108] In the embodiments of the present application, the radio frequency current is transmitted to the skin through the electrode assembly 501, and the radio frequency energy can penetrate the skin surface layer and reach the dermis layer and subcutaneous tissue. The radio frequency current generates electromagnetic waves in the skin tissue, causing water molecules and ions in the tissue to oscillate rapidly, thereby generating a frictional heat effect. This heating effect can promote the contraction of collagen fibers and the generation of new collagen proteins, effectively improving the tightness and elasticity of the skin.

[0109] The muscle layer can be reached by the micro-current, stimulating the skin muscle to repeatedly contract and relax, improving the elasticity and tension of the skin, lifting the facial contour, improving the sagging of the skin, and lightening edema. The heating effect of the radio frequency current can enhance the penetration depth of the light therapy, improving the care effect of the light on the skin tissue. At the same time, the light therapy can promote the regeneration and repair of skin cells under the action of the radio frequency current, further improving the tightness and elasticity of the skin, and improving the care effect of the skin care device. The light emitting device 100 emits light, combined with the radio frequency current and micro-current output by the electrode assembly 501, which acts on the skin to not only promote the generation of collagen proteins and form a collagen protein network, but also has the effect of lifting the face and lightening fine lines. The three have a synergistic care effect on the skin.

[0110] The radio frequency current with a frequency between 0.8MHz and 3.5MHz has multiple advantages for skin care. First, this frequency range can effectively act on the dermis layer to produce a deep heating effect without causing excessive irritation or damage to the epidermis. This deep heating not only stimulates the collagen remodeling of the skin, but also improves blood circulation, speeds up the metabolism and waste removal of the skin, thereby improving the overall skin health.

[0111] In this working mode, the radio frequency current of the electrode assembly 501 can be controlled to heat the skin to a target temperature, which is set to be greater than or equal to 41℃ and less than or equal to 43℃. In this temperature range, the collagen fibers can effectively contract and induce the generation of new collagen proteins without causing discomfort or damage to the skin. At the same time, in order to ensure that the skin temperature is maintained in the ideal range, the refrigeration piece 300 also participates in temperature control, which prevents the skin temperature from being too high by moderately cooling the light transmission piece 200, thereby ensuring the safety and comfort of the user.

[0112] Referring to FIGS. 1 and 5, in some embodiments, the skin care device 10 further comprises a mode control component 600;

[0113] The controller 400 is further configured to:

[0114] S10, in response to the operation of the mode control component 600 by the operator, the electrode assembly 501, the light emitting device 100, and the refrigeration piece 300 are controlled to work in the first working mode or the third working mode to care for the first area of the skin;

[0115] S11, after the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300 are continuously operated for a first preset time length, it is determined that the skin care device 10 completes the care of the first area, and a first warning signal is sent to prompt the operator to move the skin care device 10 to the second area;

[0116] S12, in response to the operation of the mode control component 600 by the operator, it is determined that the electrode assembly 501 and the light-transmitting device 200 are moved to the second area of the skin, and the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300 are controlled to care for the second area for a second preset time length;

[0117] S13, after the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300 are operated for a second preset time length to care for the second area, it is determined that the skin care device 10 completes the care of the second area, and a second warning signal is sent to prompt the operator to move the skin care device 10 to the third area;

[0118] S14, in response to the operation of the mode control component 600 by the operator, it is determined that the electrode assembly 501 and the light-transmitting device 200 are moved to the third area of the skin, and the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300 are controlled to care for the third area for a third preset time length;

[0119] S15, after the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300 are operated for a third preset time length to care for the third area, it is determined that the skin care device 10 completes the care of the third area, and a third warning signal is sent to prompt the operator that the care of the skin in the first working mode has been completed;

[0120] In some embodiments, the controller 400 is configured to switch between the first working mode (collagen promotion mode) and the third working mode (tight and full mode) in response to the operation of the mode control component 600 by the operator, so as to care for different areas of the facial skin.

[0121] In some embodiments, the controller 400 is configured to switch between the first working mode (collagen promotion mode) and the third working mode (tight and full mode) in response to the operation of the mode control component 600 by the operator, so as to care for different areas of the facial skin.

[0122] For example, the face is divided into three care areas: the first area is the left cheek, the second area is the right cheek, and the third area is the forehead. In the first working mode, the device synchronously operates the electrode assembly 501, the light-emitting device 100, and the refrigeration device 300, outputs radio frequency current, microcurrent, and light energy, and performs epidermal activation and collagen promotion care for each area.

[0123] First area (left cheek) treatment: After the device is started, the user places the treatment head on the first area (left cheek). The controller 400 activates the electrode assembly 501, the light-emitting device 100 and the refrigeration device 300, and the device starts to treat the first area in the first working mode. After the first preset time (e.g. 3 minutes) is over, the device determines that the treatment of the first area is completed, and sends out a first warning signal (e.g. a short beep + a short vibration) to prompt the user to move the device to the second area (right cheek). The mode light shows the breathing state, indicating that the device is ready for the treatment of the next area.

[0124] Second area (right cheek) treatment: The user moves the treatment head to the second area (right cheek) in response to the warning signal. After detecting the position change, the controller 400 continues to treat the second area in the same first working mode for a second preset time (equal to the first preset time). After the treatment is over, the device sends out a second warning signal to prompt the user to move the device to the third area (forehead).

[0125] Third area (forehead) treatment: The user moves the device to the third area (forehead) according to the prompt. In this area, the controller 400 continues to treat the skin in the first working mode, but the third preset time is shorter than the preset times of the previous two areas (e.g. 2 minutes). After the treatment is over, the device sends out a third warning signal (a long vibration + a series of short beeps), prompting the user that the treatment of the face is completed. At this time, all the mode lights are on and breathing, and the device enters the standby state. If the user does not want to use other modes, the mode control part 600 can be pressed for a long time, the device beeps for a long time, all the mode lights and the gear light are off, and the instrument is turned off; if the user wants to continue other modes, the mode control part 600 can be pressed for a short time to switch the modes.

[0126] In the third working mode, the device is also controlled through the mode control part 600, but this mode focuses on the firming and plumping effect of the face. The operation sequence is: left cheek - right cheek.

[0127] First area (left cheek) treatment: The user first places the device on the left cheek area, and starts the device to enter the third working mode. The controller 400 activates the electrode assembly 501, the light-emitting device 100 and the refrigeration device 300, and outputs stronger micro-current and moderate light energy to perform deep layer pushing and pulling and firming treatment on the skin.

[0128] Second area (right cheek) treatment: After the left cheek treatment is over, the device sends out a prompt signal, and the user moves the device to the right cheek. After detecting the position change of the device, the controller 400 continues the treatment in the third working mode. After the right cheek treatment is completed, the device sends out an end signal to prompt the user that the treatment in the firming and plumping mode is completed.

[0129] During the whole process, the user can switch modes and convert regions at any time according to the prompt signals of the device and the state of the mode light. After all the modes and region care are completed, the device enters a standby state, and the user can continue to care or turn off the device as needed. Through such intelligent and flexible operation design, the skin care device 10 provides a personalized, multi-mode comprehensive facial care experience.

[0130] Further, the first preset time length and the second preset time length are both greater than or equal to 3 min and less than or equal to 5 min, and the third preset time length is greater than or equal to 1 min and less than 3 min.

[0131] If the preset time length is too long, it will take a long time, and if the preset time length is too short, the skin care effect will not be good. Selecting an appropriate preset time length is beneficial to ensure the care effect while improving the care efficiency, and combining the user's use scene, such as the structure of the face, the first preset time length and the second preset time length are both greater than or equal to 3 min and less than or equal to 5 min, which is used for the care of the main area of the face, such as the left and right sides of the face. Such time length can fully play the care effect and improve the skin firmness and elasticity. At the same time, the third preset time length is greater than or equal to 1 min and less than 3 min, which is suitable for smaller or more sensitive areas such as the forehead, which ensures the care effect and avoids unnecessary waste of time. Through such time length setting, the device can perform efficient and accurate care in various regions, providing better skin care experience for the user, while improving the overall care efficiency.

[0132] In some embodiments, the controller 400 is further configured to control the electrode assembly 501 to output micro-currents of at least two different frequencies in a first cycle. That is, in the first working mode, micro-currents of at least two different frequencies can be output; of course, in the second working mode, the third working mode, micro-currents of at least two different frequencies can also be output.

[0133] Specifically, the first cycle includes a first period, a second period, and a third period;

[0134] The third working mode includes: in the first period, the controller 400 controls the electrode assembly 501 to output micro-currents of the first frequency, in the second period, the controller 400 controls the electrode assembly 501 to output micro-currents of the second frequency, and in the third period, the controller 400 controls the electrode assembly 501 to output micro-currents of the third frequency;

[0135] Among them, the first frequency, the second frequency, and the third frequency are three mutually different frequencies.

[0136] In some embodiments, the care process in the third working mode is designed to include a cycle of three periods, each period corresponding to the output of micro-currents of different frequencies to achieve multi-level skin care effect.

[0137] Specifically: In the first period, the controller 400 controls the electrode assembly 501 to output a first frequency of micro-current, a low-frequency micro-current mainly simulates the effect of light tapping, acting on the surface layer of the skin. This low-frequency tapping can promote the blood circulation of the skin, enhance cell vitality, and gently awaken the skin, preparing for deeper care. Low-frequency tapping helps to relax facial muscles, reduce surface tension, and lay a good foundation for subsequent care.

[0138] In the second period, the controller 400 controls the electrode assembly 501 to output a second frequency of micro-current, which is higher than the first frequency, with the effect of medium-frequency lifting. The medium-frequency micro-current deeply acts on the dermis layer and muscle layer of the skin, and through the stimulation of the current, it improves the firmness of facial muscles and the elasticity of the skin. This lifting effect can significantly improve the facial contour, resist skin relaxation, help improve fine lines and wrinkles, and make the face more firm and full.

[0139] In the third period, the controller 400 controls the electrode assembly 501 to output a third frequency of micro-current, which is the highest, with the effect of high-frequency relaxation and comfort. High-frequency micro-current mainly targets deep tissues, effectively relieving muscle fatigue and reducing the tightness caused by lifting and firming. The care in this period helps to balance the skin condition, soothe nerve endings, relax the whole face, and ultimately improve the comfort of care.

[0140] The above three-stage micro-current care can be further refined according to different skin needs and care goals, such as expanding to four stages or more. Each stage of micro-current can adjust the frequency to achieve more detailed care:

[0141] For example, a low-frequency relaxation period can be added as the first stage, through extremely low-frequency micro-current, gently massaging the skin, further relaxing the surface muscles, and making a more sufficient preparation for subsequent lifting and firming.

[0142] High-frequency revitalization and deep massage stages can also be added, using higher frequency micro-current for deep revitalization to promote cell metabolism, and combining deep massage frequency to further enhance the elasticity and luster of the skin.

[0143] Further, the first frequency is less than the second frequency, and the third frequency is greater than the second frequency;

[0144] And / or, the first frequency is 12.5Hz, the second frequency is 125Hz, and the third frequency is 9KHz.

[0145] In some embodiments, the micro-current care cycle in the third working mode includes three periods, respectively outputting micro-currents of different frequencies to achieve multi-level care effects. Specifically:

[0146] The first time period controller 400 controls the electrode assembly 501 to output a micro-current of a first frequency, the first frequency being less than the second frequency, specifically 12.5 Hz, mainly used for low-frequency patting, gently awakening the skin and promoting blood circulation.

[0147] The second time period controller 400 controls the electrode assembly 501 to output a micro-current of a second frequency, the frequency being 125 Hz, the medium-frequency lifting effect being obvious, mainly used for lifting the tightness of facial muscles and enhancing the elasticity of the skin.

[0148] The third time period controller 400 controls the electrode assembly 501 to output a micro-current of a third frequency, the third frequency being greater than the second frequency, specifically 9 KHz, the high-frequency relaxing and soothing, deeply acting on the skin, relieving the tightness and soothing muscle fatigue.

[0149] Further, the first time period is less than the sum of the second time period and the third time period. For example, the first time period is 4 seconds, the second time period is 4 seconds, and the third time period is 4 seconds. Through the combination of the frequency and the time length, the embodiment of the present application realizes the step-by-step and multi-level skin care effect, and provides the user with a comprehensive and effective facial care experience.

[0150] Continuing to refer to FIG. 3, in some embodiments, the skin care device 10 further comprises an auxiliary lighting lamp strip 700, the auxiliary lighting lamp strip 700 being used for illuminating the light-transmitting piece 200 when the skin care device 10 is working;

[0151] In the first working mode, the controller 400 is further configured to control the auxiliary lighting lamp strip 700 to emit a first illumination light;

[0152] In the second working mode, the controller 400 is further configured to control the auxiliary lighting lamp strip 700 to emit a second illumination light;

[0153] In the third working mode, the controller 400 is further configured to control the auxiliary lighting lamp strip 700 to emit a third illumination light;

[0154] The light-emitting colors, light-emitting intensities or light-emitting frequencies of at least two of the first illumination light, the second illumination light and the third illumination light are different.

[0155] In some embodiments, in the first working mode, the controller 400 is configured to control the auxiliary lighting lamp strip 700 to emit the first illumination light to cooperate with the working of the light-emitting device 100, so as to realize a better phototherapy effect.

[0156] In the second working mode, the controller 400 is configured to control the auxiliary lighting lamp strip 700 to emit the second illumination light, the light being different from the first illumination light in the light-emitting color, the intensity or the frequency, for distinguishing the cold compress mode and providing a visual prompt.

[0157] In the third working mode, the controller 400 is configured to control the auxiliary lighting lamp strip 700 to emit a third lighting light, which can be different from the first and second lighting lights in color, intensity or frequency to adapt to the different needs of the third working mode.

[0158] Specifically, the first lighting light is a red-yellow mixed light or a red light, the second lighting light is a green light or a blue light, and the third lighting light is a yellow light. In this way, in the first working mode, the first lighting light is a red-yellow mixed light or a red light, which is used for the collagen promotion care of phototherapy and micro-current. In the cold compress mode (the second working mode), the controller 400 controls the auxiliary lighting lamp strip 700 to emit the second lighting light, which is a green light or a blue light, to provide a visual prompt for cold compress.

[0159] In the third working mode, the controller 400 controls the auxiliary lighting lamp strip 700 to emit the third lighting light, which is a yellow light, to provide a warm visual feeling and enhance the comfort of care. In this way, through the lighting lights of different colors, the auxiliary lighting lamp strip 700 not only improves the operation visibility of the device, but also provides clear mode differentiation for the user.

[0160] In some embodiments, the light emitting device 100 is configured to emit light with a peak wavelength of 1400 nm ± 100 nm; and / or, the light emitting device 100 emits light with a wavelength between 630 nm and 1940 nm.

[0161] The light emitting device 100 is configured to emit light with a peak wavelength of 1400 nm ± 100 nm, i.e., to emit light in the near-infrared region, which penetrates deeper than visible pulsed light and can better penetrate the skin and tissues to provide better light and care effects for deep tissues.

[0162] The light emitting device 100 emits light with a wavelength ranging from 630 nm to 1940 nm, which can penetrate the skin surface and deep tissues, activate skin cells, stimulate the generation of collagen fibers, and achieve the effects of beauty and anti-aging.

[0163] Furthermore, the light emitting device 100 can emit light with a wavelength ranging from 630 nm to 1940 nm in these modes, and in particular, light with a wavelength ranging from 630 nm to 760 nm has a significant biological effect. For example, light with a wavelength ranging from 630 nm to 760 nm can promote the generation of adenosine triphosphate (ATP) in skin cells to provide the energy required by cells; at the same time, light with a wavelength in this band can act on mitochondria and fibroblasts to activate the function of extracellular matrix, help fission to generate more collagen proteins, and form a more stable collagen network.

[0164] With reference back to FIG. 4, in some embodiments, the skin care device 10 further comprises a temperature detection module 500 electrically connected to the controller 400, for detecting a target temperature of the skin when the electrode assembly 501 and the light emitting device 100 are working, and transmitting the detection result to the controller 400; the controller 400 is further configured to adjust the power of the electrode assembly 501 and / or the light emitting device 100 according to the detection result.

[0165] In the embodiments of the present application, the controller 400 dynamically adjusts the power of the electrode assembly 501 and / or the light emitting device 100 according to the detection result transmitted by the temperature detection module 500. When the skin temperature approaches the upper limit of the set safe range, the controller 400 automatically reduces the micro-current output power of the electrode assembly 501 and / or the light energy of the light emitting device 100 to avoid overheating of the skin and causing discomfort or damage; on the contrary, when the skin temperature is lower than the set effective temperature range, the controller 400 appropriately increases the power output of the electrode assembly 501 and / or the light emitting device 100 to ensure that the treatment effect reaches the best state.

[0166] Through the cooperation of the temperature detection module 500 and the controller 400, the skin care device 10 in the embodiments of the present application can realize fine care and adjustment of the skin under the premise of ensuring safety, thereby improving the treatment effect and user experience.

[0167] Referring to FIGS. 6-9, FIG. 6 is a structural schematic diagram of the skin care device 10 in an embodiment of the present application, FIG. 7 is a partial enlarged view of C in FIG. 6, FIG. 8 is a side view of the skin care device 10 in an embodiment of the present application, and FIG. 9 is a cross-sectional schematic view of D-D in FIG. 8.

[0168] The embodiments of the present application provide a skin care device 10, which comprises:

[0169] A housing assembly 10a, part of the housing assembly 10a forms a beauty head 101, and the beauty head 101 is provided with a light outlet 101a;

[0170] A light transmission piece 200, the light transmission piece 200 is arranged at the light outlet 101a, and the light transmission piece 200 is at least partially exposed to the housing assembly 10a;

[0171] A light emitting device 100, the light emitting device 100 is installed in the housing assembly 10a and irradiates light towards the light transmission piece 200, so as to perform light treatment on the skin through the light transmission piece 200;

[0172] A refrigeration piece 300, the refrigeration piece 300 is located in the housing assembly 10a and is in heat conduction connection with the light transmission piece 200, so as to perform refrigeration on the light transmission piece 200;

[0173] The controller 400 is electrically connected with the light-emitting device 100 and the refrigeration device 300, and the controller 400 switches and adjusts the working mode of the skin care device 10 between at least two working modes, wherein in at least one working mode, the light-emitting device 100 works to care for the skin, and in at least one working mode, the refrigeration device 300 works while the light-emitting device 100 does not work to care for the skin.

[0174] In the embodiment of the present application, the skin care device 10 comprises a housing assembly 10a, a light-transmitting member 200, a light-emitting device 100, a refrigeration device 300 and a controller 400, and each component cooperates with each other to realize multifunctional skin care. The housing assembly 10a 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 10a can be selected from lightweight and durable plastics or metals to ensure the durability and hand feeling of the device.

[0175] The light-transmitting member 200 is installed at the light outlet 101a of the cosmetic head 101 of the housing assembly 10a and partially exposes the housing assembly 10a, facilitating smooth irradiation of light onto the skin, wherein the light-transmitting member 200 can be made of transparent or translucent materials such as sapphire or glass, which have good optical conductivity and heat resistance.

[0176] The light-emitting device 100 is fixed inside the housing assembly 10a and emits light of a specific wavelength towards the light-transmitting member 200, and the light-emitting device 100 can be selected from light sources such as LEDs, laser diodes and halogen lamps, and different wavelengths of light can be selected according to specific care needs. The refrigeration device 300 closely adheres to the light-transmitting member 200 and can be connected with the light-transmitting member 200 through a heat-conducting material such as heat-conducting glue or heat-conducting copper sheet, to ensure that the light-transmitting member 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 device 300, a semiconductor refrigeration sheet or a miniature compressor refrigeration device can be used to achieve efficient temperature control.

[0177] As for the semiconductor refrigeration sheet, also known as Peltier refrigeration sheet, it is an electronic refrigeration 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, heat transfer effect will be generated. 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, thereby achieving the effect of refrigeration. Since the semiconductor refrigeration sheet does not have mechanical moving parts in the refrigeration process, it is very quiet and has no wear and tear during operation, and has high reliability. Moreover, the semiconductor refrigeration sheet is small in size and light in weight, and is suitable for integration in devices with limited space, especially handheld devices or portable devices.

[0178] The controller 400 is electrically connected to the light-emitting device 100 and the refrigeration device 300, and can adjust the working state of the device according to the mode selected by the user, so that the skin care device 10 can flexibly switch between light care, current care and cold compress care to meet different skin care needs. Specifically, the controller 400 can be implemented by using various types of control chips or integrated circuits (IC) in the embodiments of the present application. Common choices include microcontroller (MCU) chips such as the STM32 series of STMicroelectronics or the PIC series of Microchip, which can be flexibly controlled by programming to switch on and off and switch modes of the light-emitting device 100 and the refrigeration device 300. In addition, a dedicated power management chip (PMIC) can also be used to handle power distribution and switching, such as the TPS series of Texas Instruments or the ADP series of Analog Devices, which can effectively manage multiple power supplies and switch modes.

[0179] Further, the microcontroller (MCU) or other programmable chip used in the controller 400 can be programmed with a pre-set mode program. 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 buttons or other input methods in the controller 400, making the operation of the device more convenient and the function more rich.

[0180] In actual use, the user can select different care modes through the controller 400. For example, in the light care mode, the light-emitting device 100 is turned on and emits 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 refrigeration device 300 also works, and through the heat conduction connection with the light-transmitting member 200, it quickly absorbs the heat generated by the light-transmitting member 200 due to light and dissipates it, 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.

[0181] When switching to the cold compress function mode, the controller 400 will turn off the light emitting device 100 and only keep the refrigeration device 300 working, so that 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 treatment, which can reduce the skin temperature and relieve the heat and discomfort after light treatment. In addition, the user can also select the comprehensive care mode, in which the light emitting device 100 and the refrigeration device 300 work at the same time, 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 enables the skin care device 10 to not only have light and current care functions, but also provide cold compress care, so that the user can use the single cold compress function to reduce the skin temperature and reduce the probability of skin allergy during skin care, improve the comfort of the user's skin, and greatly expand the application scenarios and use effect of the device.

[0182] In the embodiment of the present application, the shell assembly 10a is partially formed with a beauty head 101 having a light outlet 101a for allowing the light generated by the light emitting device 100 to be emitted through the light-transmitting member 200 installed at the light outlet 101a. By arranging the refrigeration device 300 inside the shell assembly 10a and making it in thermal contact with the light-transmitting member 200, and by arranging the controller 400 to switch and adjust the working mode of the skin care device 10 between at least two working modes, at least one of which is that the light emitting device 100 works to care for the skin, and at least one of which is that the refrigeration device 300 works while the light emitting device 100 does not work, so that the refrigeration device 300 alone cools and cares for the skin. During use, the controller 400 can control the refrigeration device 300 to work to absorb the heat of the light-transmitting member 200 and reduce its temperature, which can avoid the problem of overheating and burning the user's skin caused by long-term use, and improve the comfort of the user when using the product. At the same time, through the setting of the controller 400, the skin care device 10 can be switched to the single cold compress function and the light treatment function, so that the user can use the single cold compress function to reduce the skin temperature and calm the skin during skin care, reduce the probability of skin allergy, and improve the comfort of the user's skin.

[0183] In some embodiments, the controller 400 switches and adjusts the working mode of the skin care device 10 between at least two working modes: in the fourth working mode, the controller 400 controls the light emitting device 100 to work and the refrigeration device 300 to cool the light-transmitting member 200; and in the fifth working mode, the controller 400 controls the refrigeration device 300 to cool the light-transmitting member 200.

[0184] In the embodiment of the present application, the controller 400 of the skin care device 10 is further optimized to control the functions of the device more flexibly in different working modes. Specifically, the controller 400 can switch and adjust between at least two working modes to meet the user's selection under different skin care needs.

[0185] In the fourth working mode, the controller 400 activates the light emitting device 100 and the refrigeration device 300 at the same time, so that the light emitting device 100 emits light of a specific wavelength for phototherapy on the skin through the light-transmitting part 200. At the same time, the refrigeration device 300 absorbs the heat generated by the light-transmitting part 200 in real time through the heat-conducting connection with the light-transmitting part 200, ensuring that the temperature of the light-transmitting part 200 is maintained at a low level, thereby avoiding overheating. This mode of simultaneous phototherapy and cold compress can provide effective light therapy while preventing skin discomfort caused by long-term light exposure, improving the overall care effect and user experience.

[0186] In the fifth working mode, the controller 400 turns off the light emitting device 100 and only keeps the refrigeration device 300 working, so that the light-transmitting part 200 continues to maintain a low temperature. This mode is mainly used for providing pure cold compress care after phototherapy to help calm the skin and reduce skin heat and discomfort that may occur after light exposure. Through the continuous cooling of the refrigeration device 300, the risk of skin burns caused by long-term light exposure can be effectively avoided, further improving the safety of the device.

[0187] The embodiment of the present application enables users to enjoy a more balanced and comfortable skin care experience during use by simultaneously activating the phototherapy and cold compress functions in the fourth working mode. The fifth working mode focuses on the cold compress function and provides soothing care immediately after phototherapy. The embodiment of the present application considers both efficient skin care and user comfort and safety. In addition, through mode switching, the skin care device 10 of the embodiment of the present application can more flexibly adapt to different user needs, increasing the functionality and convenience of the device.

[0188] Referring to FIGS. 6 and 9, in the embodiment of the present application, the skin care device 10 further includes an electrode assembly including a plurality of electrodes 5011 distributed on the periphery of the light-transmitting part 200, and each electrode 5011 is at least partially exposed to the beauty head 101. The electrode 5011 can be protruded from the surface of the beauty head 101, or flush with the surface of the beauty head 101, or recessed from the surface of the beauty head 101 by a certain distance, for outputting microcurrent and / or radio frequency current to the skin.

[0189] The embodiments of the present application introduce the electrodes 5011, greatly expand the functions of the device, so that it can not only perform phototherapy and cold compress care, but also can realize galvanic therapy on the same device.

[0190] Specifically, the output of the micro-current and / or radio frequency 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 the deep tissues of the skin and accelerate blood circulation, which helps to improve skin color and overall skin condition. In addition, the combination of the micro-current of the electrodes 5011 and the phototherapy and cold compress functions can provide more comprehensive skin care effects in different care modes.

[0191] In the embodiments of the present application, the controller 400 can incorporate the functions of the electrodes 5011 into different working modes. For example, in the fourth working mode, the light emitting device 100 and the refrigeration part 300 work at the same time, and the electrodes 5011 output micro-current and / or radio frequency current to realize the synchronous care of phototherapy and electrotherapy, further enhancing the care effect. In the fifth working mode, the light emitting device 100 is turned off, the refrigeration part 300 and the electrodes 5011 work at the same time, providing combined care of cold compress and electrotherapy to achieve the dual effect of calming the skin and deep stimulation. In the switching process of these modes, the work of the electrodes 5011 is coordinated with the phototherapy and cold compress functions to achieve more comprehensive skin care.

[0192] As for the material selection of the electrodes 5011, 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 can avoid skin allergic reactions during use. The arrangement of the electrodes 5011 takes into account the contact area and uniformity with the skin, and multiple electrodes 5011 are symmetrically distributed around the light-transmitting part 200 to ensure uniform distribution of micro-current or radio frequency current on the skin, avoiding poor care effect or skin discomfort caused by uneven current.

[0193] The skin care device 10 of the embodiments of the present application, by adding the electrodes 5011, not only can provide diversified care modes, but also can better meet the needs of users for comprehensive skin care effect, enhancing the practicality and market competitiveness of the device.

[0194] In some embodiments, the controller 400 controls the light emitting device 100 to work, the refrigeration part 300 to refrigerate the light-transmitting part 200, and the electrodes 5011 to output micro-current in the fourth working mode.

[0195] In the embodiment of the present application, the light-emitting device 100 emits light of a specific wavelength, and the light therapy is performed on the skin through the light-transmitting piece 200. The light therapy stimulates the skin cells, promotes blood circulation and collagen production, and helps to improve skin quality and reduce fine lines. At the same time, the refrigeration piece 300 is in thermal contact with the light-transmitting piece 200, and the light-transmitting piece 200 is continuously cooled by the refrigeration mechanism, so that the temperature of the light-transmitting piece 200 does not become too high during the light therapy, and the problem of skin discomfort or burns caused by long-term use is avoided.

[0196] The addition of the electrode 5011 makes the care process more comprehensive. In the fourth working mode, the electrode 5011 is activated to output a micro-current to the skin. The micro-current can simulate the biological current and apply a mild stimulus to the skin cells to promote cell metabolism and accelerate skin repair. When used in combination with light therapy, the micro-current can enhance the effect of light therapy, so that the light can 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, and at the same time, the skin can feel the tightening and lifting effect brought by the micro-current.

[0197] The fourth working mode in the embodiment of the present application considers 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 the accumulation of heat caused by the device with the assistance of cold compress, thereby improving the comfort and safety during use.

[0198] In some embodiments, the skin care device 10 further includes a sixth working mode, in which the controller 400 controls the light-emitting device 100 to work and the electrode 5011 to output a micro-current.

[0199] In the fourth working mode, the intensity of the micro-current output by the electrode 5011 is less than the intensity of the micro-current output by the electrode 5011 in the sixth working mode, and the energy of the light output by the light-emitting device 100 in the fourth working mode is greater than the energy of the light output by the light-emitting device 100 in the sixth working mode.

[0200] In the embodiment of the present application, the controller 400 of the skin care device 10 is provided with the sixth working mode to meet the diversified skin care needs of users. Specifically, the controller 400 can be switched and adjusted between the fourth working mode, the fifth working mode and the sixth working mode to realize different combinations of functions and care effects.

[0201] In the sixth working mode, the controller 400 controls the light-emitting device 100 and the electrode assembly 501 to work simultaneously, but the parameter settings are different from those in the fourth working mode. At this time, the micro-current intensity output by the electrode assembly 501 is higher than that in the fourth working mode, aiming to provide deeper skin stimulation and lifting effect. At the same time, the light energy output by the light-emitting device 100 is lower than the output level in the fourth working mode, mainly playing an auxiliary role to promote the effect of micro-current and avoid excessive light stimulation.

[0202] In such a configuration, the fourth working mode mainly focuses on the efficacy of phototherapy. The light-emitting device 100 outputs light of a specific wavelength at a high light energy, which is irradiated to the skin through the light-transmitting piece 200, achieving the effects of whitening, fading spots, and promoting collagen production. The electrode assembly 501 outputs a lower-intensity micro-current in this mode, assisting the phototherapy process and improving the overall effect of the treatment, while the refrigeration piece 300 cools the light-transmitting piece 200, ensuring comfort and safety during use.

[0203] Correspondingly, the sixth working mode focuses more on micro-current therapy. The electrode assembly 501 acts on the skin with a higher micro-current intensity, which can effectively stimulate muscles and deep tissues, achieving the effects of tightening the skin, lifting facial contours, and reducing fine lines. At this time, the light-emitting device 100 outputs light at a lower light energy, assisting the micro-current therapy and promoting the skin's response to micro-current, improving the overall effect of the treatment. 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 treatment scenarios. The refrigeration piece 300 can be selectively operated in this mode to provide a comfortable cold compress effect, further enhancing the user experience.

[0204] By adjusting the working parameters of the light-emitting device 100 and the electrode 5011 in different modes, the controller 400 can accurately control the functional output of the skin care device 10, meeting the diverse needs of users in different times and skin conditions. For example, users can choose the fourth working mode for daily basic care, using high-energy phototherapy for comprehensive skin maintenance; when they need to focus on lifting skin tightness, they can choose the sixth working mode to take full advantage of high-intensity micro-current for deep treatment.

[0205] In addition, the controller 400 can pre-burn programs for 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 treatment plan according to their own needs and achieve the best skin care effect.

[0206] In some embodiments, the controller 400 switches the working mode of the skin care device 10 among at least three working modes: the working mode in which the controller 400 controls the electrode 5011 to output micro-current and radio frequency current, the light emitting device 100 to emit light with a wavelength between 630 nm and 1940 nm, and the refrigeration piece 300 to refrigerate the light transmission piece 200; the working mode in which the controller 400 controls the electrode 5011 to output micro-current, the light emitting device 100 to emit light with a wavelength between 630 nm and 1940 nm, and the refrigeration piece 300 to refrigerate the light transmission piece 200; and the working mode in which the controller 400 controls the refrigeration piece 300 to work while the electrode 5011 and the light emitting device 100 do not work.

[0207] In the fourth working mode, the controller 400 activates the electrode 5011, the light emitting device 100, and the refrigeration piece 300 simultaneously. In this mode, the electrode 5011 outputs micro-current and radio frequency current, which, in combination with the deep heat effect of the radio frequency current and the cell stimulation effect of the micro-current, can significantly improve the tightness and elasticity of the skin. The light emitting device 100 emits specific light with a wavelength in the range of 630 nm to 1940 nm, which is irradiated onto the skin through the light transmission piece 200 to achieve a phototherapy effect, such as promoting collagen production, improving skin discoloration and dullness, etc. At the same time, the refrigeration piece 300 cools the light transmission piece 200 through the heat conduction connection with the light transmission piece 200, ensuring that the light transmission piece 200 does not overheat during the operation of the light emitting device 100, thereby improving the comfort of the user.

[0208] In the fifth working mode, the controller 400 controls the electrode 5011 to output micro-current, while the light emitting device 100 and the refrigeration piece 300 still work. This mode mainly uses the output of micro-current for relatively mild skin stimulation, which is suitable for daily basic care. Micro-current at a low current intensity can promote the vitality of skin cells and enhance the absorption effect of skincare products, while the light emitting device 100 still emits light with a wavelength between 630 nm and 1940 nm for auxiliary phototherapy to help improve skin texture and luster. The refrigeration piece 300 continues to work to maintain the appropriate temperature of the light transmission piece 200, preventing excessive heat accumulation in the skin due to phototherapy.

[0209] In the sixth working mode, the controller 400 only controls the refrigeration piece 300 to work, while the electrode 5011 and the light emitting device 100 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 transmission piece 200 by the refrigeration piece 300, 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.

[0210] Through the combination of the three working modes, the skin care device 10 can provide personalized care solutions in different use scenarios. For example, the user can select the fourth working mode when deep care is needed, and use the combined action of radio frequency current, micro-current and light therapy for intensive care; in daily care, the fifth working mode can be selected, mainly using micro-current and light therapy for mild care; when sedation and cold compress are needed, the user can select the sixth working mode to enjoy the soothing effect of cold compress.

[0211] In some embodiments, the frequency of the radio frequency current in the fourth working mode is in the range of 0.8MHz to 3.5MHz.

[0212] In the fourth working mode in the embodiments of the present application, the controller 400 controls the electrode 5011 to output a radio frequency current, and the frequency range of the radio frequency current is between 0.8MHz and 3.5MHz. 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.

[0213] The reason for adopting a frequency range of 0.8MHz to 3.5MHz is that the radio frequency current at this frequency can penetrate deep into the dermis layer of the skin, produce a mild and lasting thermal effect, not only can tighten loose skin, but also can 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 to the skin and is not easy to cause discomfort, suitable for most skin types, so as to realize effective care while ensuring the user's comfortable experience.

[0214] Referring to FIGS. 7 and 10, in some embodiments, the skin care device 10 further comprises a mode adjusting device 104 which is at least partially exposed to the shell assembly 10a for an operator to manipulate to control the controller 400 to switch and adjust the working mode of the skin care device 10 between at least three working modes. The mode adjusting device 104 is one of a button, a knob, a dial, a touch screen.

[0215] In the embodiments of the present application, the mode adjusting device 104 is at least partially exposed outside the shell assembly 10a, which is convenient for the operator to manipulate. Through the mode adjusting device 104, the user can easily control the controller 400 to switch and adjust the working mode of the skin care device 10 between at least three working modes.

[0216] Specifically, the mode adjustment device 104 can be designed as one of a button, a knob, a dial or a touch screen, providing diversified operation modes according to different use scenarios and user habits. For example, the button design is simple and intuitive, suitable for quick mode switching; the knob or dial provides more accurate mode selection, and the user can gradually adjust to the required mode; and the touch screen can display detailed information of each mode, providing a more intelligent and interactive operation experience.

[0217] In the embodiments of the present application, the introduction of the mode adjustment device 104 improves the user-friendliness of the device, enabling the operator to conveniently and quickly switch the working mode of the device, whether between different modes such as phototherapy, electrotherapy, cold compress, etc. This design not only improves the operation convenience of the device, but also enhances the user experience.

[0218] Referring to FIG. 7, in some embodiments, the skin care device 10 further comprises a mode indicator 105, which is arranged on the shell assembly 10a and close to the mode adjustment device 104, and is used to indicate at least two working modes of the skin care device 10 respectively.

[0219] In the embodiments of the present application, the mode indicator 105 is arranged on the shell assembly 10a and close to the mode adjustment device 104, so that the user can intuitively view the working mode of the device during operation. The design of the mode indicator 105 is intended to be used in cooperation with the mode adjustment device 104, to ensure that the user can conveniently confirm the current device status when switching the working mode.

[0220] Specifically, there are at least two arrangement modes of the mode indicator 105:

[0221] 1. The first arrangement mode is to arrange three different mode marks on the shell assembly 10a, each mark corresponding to an independent mode indicator 105. When the user switches to a certain mode through the mode adjustment device 104, the relevant mode indicator 105 will light up, clearly indicating the currently selected mode. This arrangement mode is intuitive and clear, suitable for users who need to quickly identify and operate.

[0222] 2. The second arrangement mode uses at least three different colors of the mode indicator 105 to represent different working modes. When the user switches the mode, the color of the indicator will change accordingly, for example, red represents the fourth working mode, blue represents the fifth working mode, and green represents the sixth working mode. This colorful indication mode not only looks beautiful, but also can provide clear mode indication in a small space.

[0223] As for the selection of the mode indicator 105, an LED lamp can be selected. Such a lamp has the characteristics of high brightness, low energy consumption and long service life, and is very suitable for use in portable devices. The LED lamp can also realize switching of multiple colors, further enhancing the user experience of the device.

[0224] Through this design, the skin care device 10 in the embodiments of the present application can effectively indicate the current working mode through the intuitive mode indicator 105 during use, making the operation of the user more clear and accurate, thereby improving the ease of use and overall experience of the device.

[0225] Referring to FIGS. 7 and 8, in some embodiments, the shell assembly 10a includes 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, the first end portion 100a forming the beauty head 101; the mode adjustment device 104 is arranged on the peripheral portion 100c.

[0226] In the embodiments of the present application, the shell assembly 10a includes 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 beauty head 101 for directly contacting and caring for the skin.

[0227] The mode adjustment device 104 is arranged on the peripheral portion 100c of the shell assembly 10a. 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.

[0228] Referring to FIG. 7, in some embodiments, the skin care device 10 further includes a heat sink 401 and a heat pipe 402, the heat sink 401 is arranged in the shell assembly 10a, one end of the heat pipe 402 of the heat sink 401 is arranged through the heat sink 401, and the other end is connected with the heating end of the refrigeration device.

[0229] In the embodiment of the present application, the skin care device 10 further comprises a radiator 401 and a heat dissipation 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 time use. The refrigeration component 300 can adopt 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, the radiator 401 and the heat dissipation pipe 402 can be added, and specifically, the radiator 401 can be arranged inside the shell assembly 10a, and a fin design structure can be adopted 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 radiator 401, which accelerates the heat dissipation process of the fins through air flow, thereby more quickly discharging the heat inside the device.

[0230] The heat dissipation pipe 402 can adopt a copper pipe with high thermal conductivity, one end of which is connected with the radiator 401, and the other end is in thermal contact with the hot end of the semiconductor refrigeration sheet. The copper pipe has good thermal conductivity, which can quickly conduct the heat generated by the hot end of the refrigeration component 300 to the radiator 401, thereby avoiding the accumulation of heat inside the device.

[0231] To further increase the heat conduction efficiency, heat-conducting silicone grease can be added between the copper pipe and the hot end of the refrigeration component 300. The heat-conducting silicone grease can fill the small gaps between the copper pipe and the hot end of the refrigeration component 300, ensuring that the heat is more effectively conducted to the copper pipe and quickly dissipated through the radiator 401 and the fan. This design not only effectively reduces the working temperature of the refrigeration component 300, but also prolongs the service life of the device and improves the comfort of the user during use.

[0232] The embodiment of the present application adds a comprehensive heat dissipation design of the radiator 401, the heat dissipation pipe 402 and the heat-conducting silicone grease, so that the skin care device 10 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 optimized design of this heat dissipation system enables the device to remain stable and efficient after long time use.

[0233] Referring to FIGS. 10-14, FIG. 10 is a side view of the skin care device 10 according to an embodiment of the present application, FIG. 11 is a cross-sectional view of E-E in FIG. 10, FIG. 12 is a local enlarged view of F in FIG. 11, FIG. 13 is a structural schematic view of the beauty head according to an embodiment of the present application, and FIG. 14 is a cross-sectional view of G-G in FIG. 13.

[0234] In some embodiments, the light-transmitting member 200 comprises a first end surface 201 facing the light-emitting device 100 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 comprising a light-transmitting region and a non-light-transmitting region, the non-light-transmitting region being located at the periphery of the light-transmitting region;

[0235] The number of the cooling members 300 is at least two, and the at least two cooling members 300 are spaced apart along the circumference of the light-transmitting member 200 and are respectively in thermal conductive connection with the non-light-transmitting region.

[0236] In the embodiments of the present application, the light-transmitting member 200 comprises a first end surface 201 facing the light-emitting device 100 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 100 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 (such as providing a mounting area for the cooling member 300).

[0237] In some embodiments, the number of the cooling members 300 is at least two, and the at least two cooling members 300 are spaced apart along the circumference of the light-transmitting member 200. Each of the cooling members 300 is in thermal conductive connection with the non-light-transmitting region of the light-transmitting member 200. By arranging the cooling member 300 in the non-light-transmitting region, it is ensured that the light emitted by the light-emitting device 100 will not be blocked, so as not to affect the phototherapy effect. At the same time, the arrangement of multiple cooling members 300 (for example, two or more) can improve the cooling efficiency and ensure that the light-transmitting member 200 maintains an appropriate low temperature state during a long period of work, preventing discomfort caused by overheating.

[0238] In order to further improve the cooling effect, a thermal conductive material such as thermal conductive silicone grease, thermal conductive gasket or thermal conductive glue can be added between the cooling member 300 and the non-light-transmitting region of the light-transmitting member 200. These thermal conductive materials can fill the gap between the cooling member 300 and the light-transmitting member 200, enhance the heat conduction efficiency, make the cooling effect more significant, and thus improve the stability of the equipment during use and the user experience.

[0239] Continuing to refer to FIGS. 13 and 14, in some embodiments, the outer edge of the second end surface 202 is a polygon with a side number greater than four;

[0240] And / or, the light-transmitting member 200 is sapphire.

[0241] The outer edge of the second end surface 202 in the embodiments of the present application is a polygon with more than four sides, which can arrange more electrodes 5011 around it, especially when interlaced current treatment is needed, this design has significant advantages. Specifically, when the second end surface 202 is a polygon (such as a pentagon, hexagon or a polygon with more sides), the device can arrange one or more electrodes 5011 at the corresponding position of each side. The increase in the number of electrodes 5011 not only increases the current coverage area of the device when 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. This design can improve the effect of current stimulation, improve the tightness and elasticity of the skin, and enhance the overall effect of care.

[0242] In some embodiments, the light-transmitting piece 200 can adopt sapphire material. Sapphire has extremely high hardness and excellent optical transmittance, and can well withstand long-term light and current output of the device, ensuring the service life and stability of the device. The combination of the sapphire light-transmitting piece 200 and the polygonal second end surface 202 makes the device not only more unique in appearance, but also more functional and durable. Through this polygonal design and material selection, the skin care device 10 in the embodiments of the present application is improved in current interlacing density and optical performance, further optimizing the user's experience and care effect.

[0243] Continuing to refer to FIG. 9, in some embodiments, the light-emitting device 100 includes at least one halogen lamp;

[0244] The skin care device 10 further includes a filter 50, which is disposed in the housing assembly 10a and located between the halogen lamp and the light-transmitting piece 200.

[0245] In the embodiments of the present application, the light-emitting device 100 includes at least one halogen lamp, which has high light output efficiency and stable spectral output, and the wavelength range of the light emitted can be adjusted between 630 nm and 1940 nm, which is suitable for various skin care applications, such as promoting collagen production, improving skin color and texture, etc.

[0246] In order to optimize the quality and effect of light, the skin care device 10 further includes a filter 50, which is disposed in the housing assembly 10a and located between the halogen lamp and the light-transmitting piece 200. The main function of the filter 50 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 only allow 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.

[0247] Specifically, the filter 50 can ensure that the transmitted light is concentrated in the most beneficial wavelength range, such as between 630 nm and 1940 nm, which can more effectively penetrate the skin and reach the deep tissue to activate the regeneration and repair of skin cells. At the same time, the filter 50 can also prevent the device from generating 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.

[0248] The skin care device 10 in the embodiments of the present application can provide more accurate and efficient phototherapy services by using a halogen lamp as the light-emitting device 100 and in combination with the use of the filter 50, which not only ensures the quality of the light but also improves the safety and stability of the device.

[0249] Referring to FIGS. 11 and 12, FIG. 11 is a cross-sectional view of E-E in FIG. 10, and FIG. 12 is a partial enlarged view of F in FIG. 11.

[0250] In some embodiments, the skin care device 10 further comprises an auxiliary lighting lamp strip 60, which is arranged on the side of the filter 50 opposite to the light-emitting device 100. The auxiliary lighting lamp strip 60 comprises green LED lamps, which are electrically connected to the controller 400. The controller 400 controls the green LED lamps to work when controlling the cooling member 300 to work.

[0251] Alternatively, the auxiliary lighting lamp strip 60 comprises blue LED lamps, which are electrically connected to the controller 400. The controller 400 controls the blue LED lamps to work when controlling the cooling member 300 to work.

[0252] In the embodiments of the present application, the auxiliary lighting lamp strip 60 is arranged on the side of the filter 50 opposite to the light-emitting device 100, aiming to provide additional light care effect for the skin care process. The design of the auxiliary lighting lamp strip 60 can be divided into two different embodiments, respectively using green LED lamps or blue LED lamps, and being electrically connected to the controller 400.

[0253] In some embodiments, the auxiliary lighting lamp strip 60 is composed of green LED lamps, which are electrically connected to the controller 400. When the controller 400 controls the cooling member 300 to work, the green LED lamps also work at the same time. The cooling member 300 cools the skin through the light-transmitting member 200, while the green light emitted by the green LED lamps irradiates on the skin.

[0254] For example, the wavelength of green light is usually between 500 nm and 570 nm, which has the effects of calming, soothing and anti-inflammatory. In combination with the cooling function, the green LED lamp 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 and reduce the inflammatory response, making the skin feel more comfortable and relaxed.

[0255] In addition to LED lights, the auxiliary light strip can also use OLED lights, cold cathode fluorescent lamps (CCFL) or organic light-emitting diodes (OLED) 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.

[0256] In some embodiments, the auxiliary light strip 60 is composed of blue LED lights, which are also electrically connected to the controller 400. In this mode, when the cooling element 300 is working, the blue LED lights are also activated. The cooling element 300 continues to provide cold compress effects to the light-transmitting element 200, while the blue light emitted by the blue LED lights shines on the skin.

[0257] For example, the wavelength of blue light is usually between 450nm and 495nm, which has the effects of antibacterial, oil control and pore shrinking. Blue light can penetrate the skin surface, help to improve oil 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.

[0258] In addition to LED lights, the auxiliary light strip can also use laser diodes, phosphor-coated 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 designs and user needs.

[0259] Referring to FIG. 11, in some embodiments, the skin care device 10 further comprises a ring-shaped reflector 70, which is arranged between the auxiliary light strip 60 and the light-transmitting element 200. The ring-shaped reflector 70 encloses a hollow inner hole, which is used for the light emitted by the auxiliary light strip 60 and the light emitted by the light-emitting device 100 to irradiate through to the light-transmitting element 200.

[0260] In the embodiments of the present application, the ring-shaped reflector 70 is arranged between the auxiliary light strip 60 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 60 and the light emitted by the light-emitting device 100 (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.

[0261] The main function of the ring-shaped reflector 70 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, while the ring-shaped reflector 70 can effectively reflect the emitted light back to the light-transmitting element 200 through its reflective properties, 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.

[0262] The reflecting surface of the annular reflector 70 can be machined into a mirror surface according to requirements to obtain higher reflectivity; or the surface can be coated with a reflective material such as an aluminum plating layer, a silver coating layer, or other high-reflectivity paint to further enhance the reflection effect of light. Through these measures, the annular reflector 70 can maximize the retention of light emitted by the light-emitting device 100 and the auxiliary lighting lamp strip 60, ensuring that the energy of the light is fully utilized.

[0263] As for the material selection of the annular reflector 70, metal materials such as aluminum or stainless steel can be used, which not only have good reflection performance but also have durability and heat dissipation performance. Alternatively, the annular reflector 70 can also be made of high-reflectivity plastic materials, which can reduce the overall weight of the device while ensuring the reflection effect.

[0264] The embodiment of the present application effectively reduces light loss by introducing the annular reflector 70, ensuring that the light emitted by the halogen lamp and the LED lamp strip can maximize the transmission through the sapphire light-transmitting piece 200, achieving 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.

[0265] Referring to FIGS. 12, 13, and 14, in some embodiments, the skin care device 10 further comprises a light-transmitting sealing piece 80, which is arranged at the end of the reflector away from the light-emitting device, and a closed cavity 203 is formed between the light-transmitting sealing piece 80 and at least a portion of the first end surface.

[0266] In the embodiment of the present application, taking the sapphire as the light-transmitting piece 200 as an example, it has two main surfaces: the surface facing the light source is the hot surface (the first end surface 201), and the surface contacting the user's skin is the 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 high-intensity light emitted by the light source. Due to continuous contact with the light source, the hot surface absorbs a certain amount of heat, and therefore has a higher temperature.

[0267] The main reason for fogging is mainly in a high-humidity environment. When the hot surface contacts the outside air, the temperature difference can cause the moisture in the air to condense on the hot surface to form fog, affecting the light transmission of the light-transmitting piece 200 and the overall performance of the device. In order to prevent the hot surface of the sapphire from fogging due to temperature difference, the light-transmitting sealing piece 80 is used in the embodiment of the present application to prevent fogging.

[0268] Specifically, the light-transmitting seal 80 and the at least partially first end surface 201 form a closed cavity 203, that is, the light-transmitting seal 80 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 100 emits light, the light-transmitting seal 80 ensures that the hot surface of the sapphire remains dry, thereby effectively preventing the occurrence of fogging and maintaining the stable output and efficient transmission of light.

[0269] In some embodiments, the light-transmitting seal 80 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 seal 80 is installed at the end of the reflector 70 away from the light-emitting device 100, and the sealing ring is provided with a protrusion towards the end of the light-transmitting piece 200, which separates the white glass and the sapphire light-transmitting piece 200 to avoid 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 seal 80 does not flow, further reducing the influence of humidity change on the hot surface.

[0270] In some embodiments, the white glass is selected as the material of the light-transmitting seal 80 because it has excellent high-temperature resistance and light-transmitting performance, and compared with acrylic material, the white glass performs more stably in a high-temperature environment. Of course, other materials with similar properties can also be selected, such as quartz glass or high-temperature resistant ceramic, which also have excellent light-transmitting and heat-resistant properties.

[0271] In order to further improve the effect of preventing fogging, the inside of the light-transmitting seal 80 can be subjected to vacuumization treatment. By vacuumizing, the air content in the light-transmitting seal 80 can be effectively reduced, thereby reducing the humidity and further preventing the fogging of the hot surface of the sapphire caused by temperature difference.

[0272] Please refer to FIG. 15 and FIG. 16, in some embodiments, the skin care device 10 includes a refrigeration module 30 and an irradiation module 102. The refrigeration module 30 includes a refrigeration piece 300. The irradiation module 102 includes a blue light emitting module 1021 and / or a green light emitting module 1022, the blue light emitting module 1021 is used for outputting a blue light signal of a preset wavelength, and the green light emitting module 1022 is used for outputting a green light signal of a preset wavelength. The blue light signal and / or the green light signal output by the irradiation module 102 is transmitted to the care area through the refrigeration module 30 to care for the care area.

[0273] The refrigeration component 300 is a refrigeration working unit of the skin care device 10 for cold therapy care, and is configured to output cooling energy during the working process of the skin care device 10 for cold therapy care. Specifically, when direct current passes through the refrigeration component 300, heat absorption phenomenon occurs at the joint, thereby cooling the surrounding environment and generating cooling energy. Therefore, when the refrigeration module 30 is working, the refrigeration module 30 can lower the temperature of the care area, and the low temperature can have the effect of soothing the skin. For example, after the skin is stimulated, the low temperature can constrict blood vessels, reduce inflammatory reactions, and relieve redness and pain. For sensitive skin or skin in the sensitive period after beauty care, the cooling effect of the refrigeration module 30 can help the skin quickly recover to a stable state and reduce discomfort.

[0274] It should be noted that the refrigeration component 300 can be a thermocouple composed of at least two different semiconductor materials. When current passes through the refrigeration component 300, electrons move in at least two different semiconductor materials in the refrigeration component 300. Due to the difference in electron energy band structure of different materials, the electrons will absorb or release energy during the transfer from one material to another. At the refrigeration end, the electrons absorb heat, causing the temperature to decrease, and the cooling energy is transferred to the object in contact with it by heat conduction, such as transferring cooling energy to the contact surface of the skin care device 10 and the skin.

[0275] The blue light signal and / or green light signal output by the blue light emitting module 1021 and the green light emitting module 1022 in the irradiation module 102 are transmitted to the care area through the refrigeration module 30 to care for the care area.

[0276] The blue light emitting module 1021 generally uses a blue light emitting diode (LED) of a specific wavelength as the main light source, and can also include lenses, mirrors, filters, etc. The lens is used to focus and diffuse the blue light to meet different application requirements. The mirror can reflect the blue light to a specific direction to improve the utilization rate of the light. The filter can filter out unwanted wavelengths and allow specific wavelengths of blue light to pass through to improve the purity and quality of the blue light.

[0277] The wavelength range of the blue light signal is generally between 455-475 nanometers. In the field of beauty care, blue light of a specific wavelength has the effect of sterilization and anti-inflammatory, and can accelerate cell metabolism. The wavelength of the green light signal is generally between 500-520 nanometers. Green light has the effect of soothing and calming in care. For sensitive skin, green light can reduce symptoms such as redness and itching of the skin. In this way, the immune system of the skin is adjusted, the resistance of the skin is enhanced, and the impact of external stimuli on the skin is reduced.

[0278] When the blue light signal and / or the green light signal pass through the refrigeration module 30 to the treatment area, due to the simultaneous action of the two on the same piece of skin, the bactericidal, anti-inflammatory, soothing and cell metabolism accelerating effects of the blue light, or the soothing and calming effects of the green light, can enhance the calming effect of the refrigeration module on the skin, while accelerating the metabolism of cells, so that new cells reach the skin surface more quickly and then soothe and calm, achieving a synergistic effect on the skin.

[0279] In some embodiments, the blue light emitting module 1021 and the green light emitting module 1022 can each include a light emitting element 1023, which can be a laser diode, serving as the light source of the blue light emitting module 1021 and the green light emitting module 1022, respectively.

[0280] Please continue to refer to FIG. 15. In some embodiments, the refrigeration module 30 further includes a light-transmitting cold guide 1012. The light-transmitting cold guide 1012 is located on one side of the refrigeration element 300, and the cooling energy generated by the refrigeration element 300 is transmitted to the treatment area through the light-transmitting cold guide 1012. The blue light signal output by the blue light emitting module 1021 is transmitted to the treatment area through the light-transmitting cold guide 1012. And / or, the green light signal output by the green light emitting module 1022 is transmitted to the treatment area through the light-transmitting cold guide 1012.

[0281] The light-transmitting cold guide 1012 has good light transmission capability, so that the blue light signal and the green light signal emitted by the blue light emitting module 1021 and / or the green light emitting module 1022 can pass through the component and reach the treatment area.

[0282] Because different materials have different light transmission rates for different wavelengths of light, when selecting the material of the light-transmitting cold guide 1012, the matching with the specific blue light and green light wavelengths used by the beauty instrument needs to be considered. For example, for the blue light signal and the green light signal of a predetermined wavelength emitted by the blue light emitting module 1021 and / or the green light emitting module 1022, optical glass or transparent plastic has a high transmission rate, which can ensure that the loss of the light signal during transmission is minimized.

[0283] In some embodiments, the light-transmitting cold guide 1012 can be directly attached to the surface of the refrigeration element to minimize thermal resistance and ensure rapid transmission of cooling energy. Alternatively, the two can be connected by a specific heat-conducting medium to optimize heat transfer efficiency while taking into account the stability and maintainability of the structure.

[0284] The refrigeration component 300 can be a component that generates cooling energy in the skin care device 10. For example, the refrigeration component 300 can be a semiconductor refrigeration sheet that generates cooling energy by switching on and off of electric current using the Peltier effect, or by compressing refrigerant. After the refrigeration component 300 outputs the cooling energy, the cooling energy is transmitted to the light-transmitting cold-conducting component 1012, which can transmit the cooling energy to the care area.

[0285] Further, while the refrigeration component 300 generates cooling energy, the blue light emitting module 1021 and / or the green light emitting module 1022 can output corresponding blue light signals and / or green light signals.

[0286] The simultaneous output of cooling energy and light signals can play a synergistic role to enhance the care effect on the care area. For example, the cooling energy can constrict skin blood vessels and reduce inflammatory reactions, and in combination with the sterilization effect of blue light, it can more effectively care for skin problems such as acne. The soothing effect of green light can also be enhanced in a cooling environment, providing better care for sensitive skin. At the same time, since blue light and / or green light also generate some heat, transmitting blue light and / or green light to the care area through the light-transmitting cold-conducting component is also conducive to the refrigeration component further reducing the heat of blue light and / or green light, thereby reducing the heat reaching the skin and playing a role in cell cryotherapy.

[0287] Please refer to FIGS. 17-19, in some embodiments, the skin care device 10 further comprises a ring-shaped light reflector 70, which is arranged between the blue light emitting module 1021 or the green light emitting module 1022 and the light-transmitting cold-conducting component 1012. The ring-shaped light reflector 70 encloses a hollow inner hole, which is used for the light emitted by the light emitting elements in the blue light emitting module 1021 or the green light emitting module 1022 to irradiate through to the light-transmitting cold-conducting component 1012 and be transmitted to the care area.

[0288] In the embodiments of the present application, the ring-shaped light reflector 70 is in a ring shape, and the ring shape can surround one side of the blue light emitting module 1021 or the green light emitting module 1022, providing a continuous and uniform reflection surface for light reflection. Moreover, the hollow part of the ring shape can allow light to pass through and form a specific light path channel, reducing light loss and ensuring that light can accurately irradiate to the target area.

[0289] After the light irradiates to the light-transmitting cold-conducting component 1012 through the hollow inner hole, it is then transmitted to the care area by the light-transmitting cold-conducting component 1012. In this process, the hollow inner hole plays a bridging role between the light emitting module and the care area, ensuring that the light will not be blocked or scattered by other objects during transmission, so that the light can efficiently reach the care area and achieve the purpose of skin care.

[0290] In some embodiments, the light-transmitting cold-conducting member 1012 is sapphire. Sapphire has extremely high transparency, and has very high transmittance for visible light, especially in the wavelength bands corresponding to blue light signals and green light signals, so that signals from the blue light emitting module 1021 and the green light emitting module 1022 can almost completely pass through the sapphire without loss, ensuring the effectiveness of phototherapy. Whether the blue light of a specific wavelength is used for sterilization and anti-inflammatory, or the green light is used for soothing and calming, it can reach the care area with the maximum intensity and play its due care role.

[0291] In addition, sapphire has high thermal conductivity and can quickly and effectively conduct the cooling energy generated by the refrigerating member 300. When the refrigerating member 300 is working, the sapphire as the light-transmitting cold-conducting member 1012 can quickly transfer the cooling energy to the care area, realizing efficient cold therapy. This rapid heat conduction capability can ensure that the care area cools down quickly, contracts blood vessels, and reduces inflammation, providing a comfortable care environment for the skin.

[0292] Due to the excellent light-transmitting and cold-conducting properties of sapphire, it can perfectly combine phototherapy and cold therapy, and improve the care effect of the skin care device 10. For skin problems such as acne and comedones, the sterilization and anti-inflammatory effect of blue light and the cooling and blood vessel contraction effect of cold therapy can synergize to relieve symptoms faster. For sensitive skin, the soothing and calming effect of green light and the comfortable care of cold therapy can better alleviate the discomfort of the skin.

[0293] At the same time, the uniform light-transmitting and cold-conducting properties of sapphire can ensure that every part of the care area can be fully cared for, avoiding the problem of poor local care effect.

[0294] Please continue to refer to FIG. 15, FIG. 17 to FIG. 19, in some embodiments, the light-transmitting cold-conducting member 1012 includes a first end surface 201 facing the skin and a second end surface 202 opposite the first end surface, the first end surface of the light-transmitting skin-adhesive member abuts the skin for caring for the care area;

[0295] The blue light emitting module 1021 and / or the green light emitting module 1022 are arranged on the side opposite the second end surface 202.

[0296] In the embodiments of the present application, the light-transmitting and cold-conducting member 1012 has two clearly distinguished end faces, namely the first end face 201 facing the skin and the second end face 202 opposite to the first end face 201, which helps to clearly determine the functional direction thereof in use. The first end face 201 directly contacts the skin of the treatment area and undertakes the key task of delivering the light therapy and cold therapy to the skin. The second end face 202 is usually connected with the internal components such as the refrigerating member 300 and the light-emitting module, and can be used to receive the cooling energy from the refrigerating member 300 and the light signals from the blue light-emitting module 1021 and / or the green light-emitting module 1022, and conduct the cooling energy and the light signals to the first end face 201.

[0297] The close contact of the first end face 201 with the skin is an important way to achieve effective treatment, which can ensure that the cooling energy and the light signals can directly act on the treatment area and minimize the energy loss and signal scattering. When the first end face 201 closely contacts the skin, the cooling energy generated by the refrigerating member 300 can be quickly transmitted to the skin surface, so that the skin temperature is reduced and the cold therapy effect is achieved.

[0298] At the same time, the blue light signals and / or green light signals emitted by the blue light-emitting module 1021 and / or the green light-emitting module 1022 can be efficiently transmitted to the skin through the first end face 201 of the light-transmitting and cold-conducting member 1012, and play their specific treatment roles. For example, the blue light can kill bacteria and relieve inflammation, and the green light can soothe and calm, so as to perform targeted light therapy on the treatment area.

[0299] Please continue to refer to FIG. 16, in some embodiments, the skin treatment device 10 further comprises a control module 4000, which is electrically connected with the refrigerating module 30 and the irradiation module 102, and is used to output a control instruction for controlling the refrigerating module 30 and the irradiation module 102 to perform skin treatment. After receiving the control instruction, the refrigerating module 30 and the irradiation module 102 start to work to treat the treatment area.

[0300] In the embodiments of the present application, the control module 4000 serves as the core control unit of the skin treatment device 10 and plays a crucial coordinating role. The control module 4000 is electrically connected with the refrigerating module 30 and the irradiation module 102, and can accurately control the operating states of these two key modules. By outputting specific control instructions, the control module 4000 can determine when the refrigerating module 30 and the irradiation module 102 start to work, at what intensity they work, and how long they work, etc.

[0301] For example, when performing skin care, the control module 4000 can start the refrigeration module 30 in a timely manner according to the user's needs and skin conditions, so that the refrigeration module 30 generates cooling energy to reduce the temperature of the care area and relieve skin inflammation or redness and other problems. At the same time, the control module 4000 can also control the irradiation module 102 to output blue light or green light signals of specific wavelengths to achieve different care effects such as sterilization, anti-inflammatory, soothing, and calming.

[0302] Please continue to refer to FIG. 16. In some embodiments, the skin care device 10 further includes a mode selection module 106 for selecting the working mode of the skin care device 10, wherein the working mode of the skin care device 10 includes a cold therapy mode, and the mode selection module 106 is electrically connected to the control module 4000.

[0303] In the embodiments of the present application, the control module 4000 is configured to control the refrigeration module 30 and the irradiation module 102 to work when receiving an input signal that the mode selection module 106 selects the cold therapy mode.

[0304] The control module 4000 is electrically connected to the mode selection module 106 and can receive the input signal sent by the mode selection module 106 in real time. When the user selects the cold therapy mode through the mode selection module 106, the control module 4000 will immediately respond to this input signal and control the refrigeration module 30 and the irradiation module 102 to work according to the preset parameters of the cold therapy mode.

[0305] Specifically, the control module 4000 will adjust the working parameters of each module according to the requirements of the cold therapy mode to ensure that the device can stably and effectively work in the cold therapy mode. For example, the control module 4000 can increase the power of the refrigeration module 30 to quickly reduce the temperature of the care area; at the same time, the working state of the irradiation module 102 is adjusted to match the cold therapy mode.

[0306] Please continue to refer to FIG. 15. In some embodiments, the mode selection module 106 includes at least one mode selection control component 1061, and the at least one mode selection control component 1061 is located on the outer side of the skin care device 10.

[0307] The control module 4000 controls the refrigeration module 30 and the irradiation module 102 to perform skin care at the same time or within a preset time interval when receiving an input signal that the mode selection control component 1061 selects the cold therapy mode.

[0308] In the embodiments of the present application, at least one mode selection control component 1061 in the mode selection module 106 is a key part for the user to interact with the skin care device 10, which can have various forms such as physical buttons, knobs, touch-sensitive areas, etc., allowing the user to conveniently select different working modes to meet individual skin care needs.

[0309] The mode selection control component 1061 is located on the outer side of the skin care device 10, which improves the user's operation convenience. The user does not need to open the device or perform complex operations to directly find and operate these mode selection control components 1061 on the surface of the device. Such a layout makes the device more intuitive and easy to use, improving the user's experience.

[0310] The control module 4000 is electrically connected with the mode selection control component 1061 and can receive input signals from these components in real time. When the user operates the mode selection control component 1061 to select the cold therapy mode, the control module 4000 will immediately perceive this signal and start corresponding processing. This fast response capability is the key to ensuring that the device can meet the user's needs in a timely manner. The control module 4000 will identify the cold therapy mode selected by the user according to the type and content of the input signal and prepare to control the refrigeration module 30 and the irradiation module 102.

[0311] The mode selection module 106 includes at least one mode selection control component 1061, and the at least one mode selection control component 1061 is located on the outer side of the skin care device 10.

[0312] When the control module 4000 receives the input signal of the cold therapy mode from the mode selection control component 1061, it controls the refrigeration module 30 and the irradiation module 102 to perform skin care at the same time or within an interval less than a preset time.

[0313] Once the input signal of the cold therapy mode is received, the control module 4000 controls the refrigeration module 30 and the irradiation module 102 to perform skin care at the same time or within an interval less than a preset time. In the cold therapy mode, the refrigeration module 30 and the irradiation module 102 work closely together to provide effective care for the care area.

[0314] The control module 4000 can control the refrigeration module 30 and the irradiation module 102 to work within an interval less than a preset time, thereby realizing the cooperative work of the refrigeration module 30 and the irradiation module 102, and realizing the user's selection of different working modes and the efficient cooperation between the modules of the device.

[0315] In some embodiments, the interval less than the preset time can be that the refrigeration module 30 and the irradiation module 102 work simultaneously, and the working mode of the refrigeration module 30 and the irradiation module 102 working simultaneously can maximize the synergistic effect of cold therapy and light therapy. The refrigeration module 30 can relieve symptoms such as inflammation and swelling by reducing the temperature of the care area, and the specific wavelength light output by the irradiation module 102 can have the effects of sterilization, anti-inflammatory, and collagen production promotion. The simultaneous action of the two can improve the care effect and improve the care efficiency.

[0316] In some embodiments, the working mode of the skin care device 10 further includes a light-heat synergy mode or a multi-section mode.

[0317] The control module 4000 controls the electrode module and the heating module in the skin care device 10 to work when receiving the input signal of the mode selection module selecting the light-heat synergy mode; or,

[0318] The control module 4000 controls the electrode module in the skin care device 10 to cyclically switch the skin care work when receiving the input signal of the mode selection module 106 selecting the multi-section mode.

[0319] In the embodiments of the present application, the skin care device 10 can include multiple working modes, and the multiple working modes can include a cold therapy mode, a light-heat synergy mode, and a multi-section mode. The cold therapy mode can be a mode in which the control module 4000 controls the refrigeration module 30 and the irradiation module 102 to work simultaneously, and is used for cold therapy care of the care area. The light-heat synergy mode refers to that the skin care device 10 simultaneously uses an electrical signal and a light signal to perform collaborative heating care on the care area. In this mode, the electrical signal can heat the subcutaneous tissue of the care area, and the light signal can heat the skin surface of the care area, thereby realizing light-heat collaborative heating of the care area. The multi-section mode can be a mode of performing care in stages. In this mode, the skin care device 10 can activate and pat the care area according to a preset frequency band, and can also cyclically switch the frequency band of the care area to be activated and pat, thereby realizing multi-section care of the care area.

[0320] In some embodiments, after determining that the skin care device 10 executes the light-heat synergy mode or the multi-section mode, the control module 4000 controls the refrigeration module 30 and the irradiation module 102 to perform skin care.

[0321] In the embodiments of the present application, the skin care device 10 can also start a cold therapy mode or a light therapy mode for cold therapy care of the care area after the operation of the photo-thermal synergistic mode and / or the multi-stage mode, wherein the cold therapy mode after the photo-thermal synergistic mode and / or the multi-stage mode can be used to relieve the irritation to the skin in the process of the photo-thermal synergistic mode and / or the multi-stage mode care.

[0322] In some embodiments, the preset wavelength of the blue light signal output by the blue light emitting module 1021 is in the range of 455nm to 475nm. The blue light signal with the wavelength in the range of 455nm to 475nm can penetrate a certain depth of the skin, act on specific cells or tissues in the skin, produce singlet oxygen, thereby killing bacteria and reducing inflammation, so as to have the effects of sterilization and inflammation reduction.

[0323] In some embodiments, the preset wavelength of the green light signal output by the green light emitting module 1022 is in the range of 500nm to 520nm. The green light signal with the wavelength in the range of 500nm to 520nm can penetrate a certain depth of the skin, act on specific skin cells or tissues, and for sensitive skin or irritated skin, the green light can help to reduce inflammation, relieve redness, promote repair and regeneration of the skin, thereby having the effects of soothing and calming.

[0324] Please refer to FIGS. 20 to 25, in some embodiments, the skin care device 10 comprises a working head 101b, a radio frequency working module 108, a light working module 110 and a controller 400. The front end of the working head 101b can be in contact with the skin, the radio frequency working module 108 comprises a plurality of electrodes 5011 for outputting radio frequency current to the skin, the light working module 110 comprises a light emitting device 100, and the light working module 110 can be used to emit light with a wavelength between 630nm and 1940nm; the controller 400 is electrically connected with the radio frequency working module 108 and the light working module 110, and the controller 400 is used to output a control instruction for controlling the radio frequency working module 108 and the light working module 110 to work simultaneously, so as to irradiate the skin with light and act on the skin with radio frequency current.

[0325] In the embodiments of the present application, the front end of the working head 101b can be in contact with the skin, for efficiently delivering the energy generated by the radio frequency working module 108 and the light working module 110 to the skin tissue. Specifically, when the radio frequency working module 108 generates radio frequency current, the contact between the working head 101b and the skin can make the radio frequency current generated by the radio frequency working module 108 act more directly on the deep tissue of the skin, such as the dermis. Similarly, the light with specific wavelength emitted by the light working module 110 can also be more effectively irradiated to the surface and deep layer of the skin through the working head 101b, to achieve the function of skin care.

[0326] It's important to note that the working head 101b is not only the point of physical contact but also a crucial medium for energy transfer. Furthermore, the working head 101b can integrate multiple functions, enabling 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 101b can massage the skin through vibration or rotation, promoting blood circulation and metabolism. Simultaneously, the working head 101b can be used in conjunction with skincare products to deliver nutrients deeper into the skin, enhancing the absorption of these products.

[0327] In this embodiment, the radio frequency (RF) module 108, as an important component of the skin care device 10, is primarily responsible for generating and outputting RF current. The circuit system generates RF signals of specific frequency and intensity, and the electrodes are key components for outputting the RF current to the skin. The presence of several electrodes 5011 allows the RF current to act more evenly on 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 parts of the working head to simultaneously perform RF care on a large area of ​​skin.

[0328] When the 5011 electrodes deliver radiofrequency current to the skin, the 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.

[0329] In this embodiment, the light-emitting device 100 in the light-working module 110 is the core component for generating light of a specific wavelength. The light-emitting device 100 may include a light-emitting diode (LED), a laser diode, etc. The light-emitting device 100 has advantages such as high efficiency, stability, and long lifespan, and can continuously emit light of the desired wavelength. For example, the light-emitting device 100 may include at least one halogen lamp 1001 for heating the skin in the treatment area corresponding to the skin care device 10 to achieve skin care.

[0330] The performance of the light-emitting device 100 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 measuring the quality of the light-emitting device. High-quality light-emitting devices can ensure that the output light has sufficient intensity and stability to achieve effective skin care.

[0331] The light working module 110 can be used to emit light with wavelengths between 630nm and 1940nm. Light in this wavelength range has specific biological effects and is important for skin care. Light of different wavelengths can penetrate the skin to different depths and act on different skin tissues, thereby achieving different care effects. For example, near-infrared light (wavelength about 630nm-1400nm) can penetrate deep into the skin, promote cell metabolism and collagen production, and help improve skin elasticity and firmness. While mid-infrared light (wavelength about 1400nm-1940nm) can produce a warming effect and accelerate blood circulation.

[0332] Furthermore, light with wavelengths between 630nm and 760nm can promote the production of adenosine triphosphate (ATP) and act on mitochondria or fibroblasts, causing the extracellular matrix to help split more collagen and form a collagen network. Light with wavelengths between 630nm and 1940nm can stimulate the activity of skin cells, promote cell regeneration and repair, and also improve skin texture and color.

[0333] In the embodiments of the present application, the controller 400 is electrically connected to the radio frequency working module 108 and the light working module 110, so that the controller 400 can effectively communicate and control these two modules. Control instructions can include start / stop instructions, mode selection instructions, parameter adjustment instructions, etc. For example, the controller 400 can send a start instruction to make the radio frequency working module 108 and the light working module 110 start working at the same time; it can also send a parameter adjustment instruction to adjust the intensity and frequency of the radio frequency current emitted by the radio frequency working module 108, and the intensity and wavelength of the light output by the light working module 110, etc.

[0334] Please refer to FIG. 20 and FIG. 25, in some embodiments, the front end of the working head 101b is provided with a light-transmitting window 101c, the light-transmitting window 101c is provided with a light-transmitting piece 200, the light-transmitting piece 200 is located on the side of the light-emitting device 100 facing the skin, and the light emitted by the light-emitting device 100 forms light with wavelengths between 630nm and 1940nm after passing through the light-transmitting piece 200.

[0335] The front end of the working head 101b is provided with a light-transmitting window 101c, which can be used to allow light to directly irradiate the skin surface, so as to realize the skin care effect of the light working module 110. The light-transmitting window 101c serves as a channel for light propagation, and ensures that the light emitted by the light emitting device 100 can smoothly reach the skin. The light-transmitting window 101c is provided with a light-transmitting piece 200, which plays a role of filtering and conducting light. The light-transmitting piece 200 is located on the side of the light emitting device 100 facing the skin, can receive the light emitted by the light emitting device 100, and transmit the light to the skin after processing. The light-transmitting piece 200 has good light-transmitting property, can allow light of a specific wavelength to pass through, and block other unnecessary wavelengths or interference light.

[0336] In some embodiments, the plurality of electrodes 5011 are arranged at the periphery of the light-transmitting window 101c; and / or,

[0337] The plurality of electrodes 5011 also output micro-current to the skin.

[0338] In the embodiments of the present application, the plurality of electrodes 5011 are arranged at the periphery of the light-transmitting window 101c, so that the plurality of electrodes 5011 and the light-transmitting window 101c can work cooperatively in a limited space without interfering with each other. Specifically, the plurality of electrodes 5011 output the radio frequency current output by the radio frequency working module 103 at the periphery of the light-transmitting window 101c, and the light-transmitting window 101c allows the light output by the light working module 110 to irradiate the skin. The close position of the two can make the radio frequency current and the light interact with each other on the skin surface and the shallow tissue, so as to produce a better skin care effect. In addition, arranging the plurality of electrodes 5011 at the periphery of the light-transmitting window 101c can make up for the energy attenuation of the light output by the light working module 110 at the periphery (the energy at the periphery is small due to the refraction, reflection and scattering of light), so as to improve the care effect of the skin care device 10.

[0339] The plurality of electrodes 5011 also output micro-current to the skin, which can reach the muscle layer, stimulate the repeated contraction and relaxation of the skin muscle, improve the elasticity of the skin, improve the facial contour, improve the sagging of the skin, and reduce edema.

[0340] In some embodiments, the light working module 110 emits light with a wavelength of 630nm-1940nm, in combination with the radio frequency current and the micro-current output by the electrodes 5011, which act on the skin, not only beneficial to the generation of collagen and the formation of collagen network, but also have the effect of lifting the face and reducing fine lines, and the three have a synergistic care effect on the skin.

[0341] Please refer to FIG. 22 and FIG. 23, in some embodiments, the skin care device 10 further comprises a temperature detection module 500, which is arranged at the front end of the working head 101b and electrically connected with the controller 400, for detecting the target temperature of the skin when the radio frequency working module 108 and the light working module 110 work and transmitting the detection result to the controller 400; the controller 400 is further used for adjusting the power of the light working module 110 and / or the radio frequency working module 108 according to the detection result.

[0342] In the embodiments of the present application, the working head 101b directly contacts the skin, and the temperature detection module 500 arranged at the front end of the working head 101b can be closest to the care area, so as to more accurately detect the actual temperature of the skin or the working head 101b. When the radio frequency working module 108 and the light working module 110 care the skin, the temperature change first occurs in the area contacted by the working head, so that the temperature detection at this position can timely reflect the temperature change of the skin during the care process.

[0343] When detecting the temperature of the care area, the temperature detection module 500 can detect the temperature of the light-transmitting piece 200 in the working head 101b and take the temperature of the light-transmitting piece 200 as the target temperature for detecting the temperature of the skin. When detecting the temperature of the care area, the temperature detection module 500 can also directly detect the temperature at the position closest to the skin surface layer, so as to determine the target temperature of the skin detected by the temperature detection module 500. The temperature detection module 500 can also detect the temperature of the electrode 5011 in contact with the skin and take the temperature of the electrode 5011 as the target temperature for detecting the temperature of the skin.

[0344] Please refer to FIG. 22 and FIG. 23, in some embodiments, the temperature detection module 500 comprises a temperature sensor 1071 arranged on the electrode 5011.

[0345] The controller 400 further comprises a light emitting device adjusting unit 1041 electrically connected with the temperature detection module 500 and the light emitting device 100, respectively, for receiving the temperature detection signal input by the temperature detection module 500 and adjusting the working voltage value of the light emitting device 100 according to the temperature detection signal.

[0346] Since the several electrodes 5011 are in close contact with the skin when working, the temperature sensor 1071 arranged on the electrode 5011 can more directly perceive the temperature change of the skin. When the radio frequency working module 108 outputs the radio frequency current acting on the skin through the several electrodes 5011, the temperature change of the care area of the skin is more significant, so that arranging the temperature sensor 1071 at this position can more accurately monitor the temperature information of the skin care device 10 during the care process.

[0347] The light-emitting device adjustment unit 1041 in the controller 400 is electrically connected with the temperature detection module 500 and the light-emitting device 100 respectively. Thus, the light-emitting device adjustment unit 1041 can receive the temperature detection signal input by the temperature detection module 500. The temperature detection signal contains the temperature information of the current skin and 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 temperature change of the skin so as to make corresponding adjustment to the light-emitting device.

[0348] In the embodiment of the present application, the temperature sensor 1071 in the temperature detection module 500 is arranged on the electrode 5011, which can more accurately monitor the temperature change of the skin. The light-emitting device adjustment unit 1041 in the controller 400 can realize accurate control of the skin temperature and optimization of the phototherapy effect by receiving the temperature detection signal and adjusting the working voltage value of the light-emitting device 100, thereby improving the safety and effectiveness of the skin care device 10.

[0349] In some embodiments, the frequency of the radio frequency signal output by the radio frequency working module 108 is in the range of 0.8 MHz to 3.5 MHz, and / or the wavelength of the light emitted by the light working module 110 is in the range of 1400 nm ± 100 nm, and / or,

[0350] The wavelength of the light emitted by the light working module 110 contains the range between 630 nm and 670 nm.

[0351] The radio frequency signal with the frequency in the range of 0.8 MHz to 3.5 MHz can realize the effect on multiple depths of the skin and can act on different depths of the skin to generate a thermal effect in the tissues at different depths of the skin. When the radio frequency signal acts on the skin, it can cause molecular vibration in the skin tissues at different depths, thereby generating heat. This thermal effect can stimulate the contraction and regeneration of collagen, promote the firmness and elasticity of the skin. At the same time, appropriate thermal effect can also improve the blood circulation of the skin, increase the nutrition supply of the skin, and promote the metabolism of the skin cells.

[0352] The light with the wavelength in the range of 1400 nm ± 100 nm can better interact with the components such as water and collagen in the skin tissues, produce a specific biological effect, effectively heat the water in the skin tissues, and thus cause the contraction and regeneration of collagen. At the same time, it can also stimulate the activity of the skin cells, promote the metabolism and repair of the cells.

[0353] Light with wavelength in the range of 630nm-670nm can promote cell metabolism, increase collagen production, improve skin elasticity and tightness, and promote the production of adenosine triphosphate (ATP), and act on mitochondria or fibroblasts, so that the extracellular matrix helps to split more collagen to form a collagen network.

[0354] Referring to FIG. 23, in some embodiments, the skin care device 10 further comprises a radio frequency signal detection module 109, which is electrically connected to the controller 400, and is configured to detect the frequency of the radio frequency signal when the radio frequency working module 108 is working, and transmit the detection result to the controller 400; the controller 400 is further configured to adjust the power of the radio frequency working module 108 according to the detection result.

[0355] In the embodiments of the present application, the radio frequency signal detection module 109 is electrically connected to the controller 400, and can quickly and accurately transmit the related data of the radio frequency signal to the controller 400 in the form of an electrical signal, so as to ensure that the controller 400 can obtain the working state information of the radio frequency signal detection module 109 in time.

[0356] The frequency of the radio frequency signal is an important parameter, which directly affects the skin care effect of the radio frequency working module 108, and different frequencies will result in different penetration depths and action modes of the radio frequency energy in the skin. The radio frequency signal detection module 109 detects the frequency of the radio frequency signal in the embodiments of the present application, and transmits the detected radio frequency signal frequency result to the controller 400, so as to provide the controller 400 with key information about the working state of the radio frequency working module 108.

[0357] In order to ensure that the controller 400 can know the running condition of the radio frequency working module 108 at any time, the radio frequency signal detection module 109 can be controlled to perform real-time detection and transmission, so that the controller 400 can adjust the control strategy of the radio frequency working module 108 in time according to the received detection result, so as to achieve better skin care effect.

[0358] The controller 400 is configured to adjust the power of the radio frequency working module 108 according to the detection result transmitted by the radio frequency signal detection module 109. When the controller 400 receives the radio frequency signal frequency information detected by the radio frequency signal detection module 109, it will determine whether the power of the radio frequency working module 108 needs to be adjusted according to the detected radio frequency signal frequency information. If the detection result shows that the frequency of the radio frequency signal deviates from the preset ideal frequency, the controller 400 can adjust the power of the radio frequency working module 108 to make the frequency of the radio frequency signal return to the appropriate range.

[0359] The radio frequency signal detection module 109 in the skin care device 10 cooperates with the controller 400 to detect the frequency of the radio frequency signal and transmit the result to the controller 400, and the controller 400 adjusts the power of the radio frequency working module 108 according to the detection result, so as to realize accurate control of the skin care device 10, optimize the skin care effect, and ensure the safe and stable operation of the device.

[0360] Referring to FIG. 23, in some embodiments, the controller of the skin care device 10 further includes a frequency adjustment unit 1042 connected with the electrode 5011 and the radio frequency signal detection module 109 respectively, for receiving the frequency detection signal input by the radio frequency signal detection module 109 and adjusting the working voltage of the electrode 5011 according to the frequency detection signal.

[0361] In the embodiments of the present application, the frequency adjustment unit 1042 receives the frequency detection signal input by the radio frequency signal detection module 109. The frequency detection signal can include information about the frequency of the radio frequency signal currently output by the radio frequency working module 108. After receiving the information about the frequency of the radio frequency signal, the controller 400 can determine the real-time working state of the radio frequency working module 108, such as the change of the frequency of the radio frequency signal. Specifically, adjusting the working voltage of the electrode 5011 can directly affect the frequency of the radio frequency signal output by the radio frequency working module 108. There is a corresponding relationship between the working voltage of the electrode 5011 and the frequency of the radio frequency signal. By adjusting the working voltage of the electrode 5011, the frequency of the radio frequency signal can be adjusted.

[0362] It should be noted that adjusting the working voltage of the electrode 5011 to control the frequency of the radio frequency signal can optimize the skin care effect. Different skin conditions and care needs may require radio frequency signals of different frequencies. By accurately adjusting the working voltage of the electrode 5011 to control the frequency of the radio frequency signal, the radio frequency working module can output the radio frequency signal most suitable for the current skin care needs. Therefore, the frequency adjustment unit 1042 in the controller 400 of the skin care device 10 can receive the frequency detection signal input by the radio frequency signal detection module 109 and adjust the working voltage of the electrode 5011 according to the signal, so as to realize accurate control of the frequency of the radio frequency signal output by the radio frequency working module 108, which helps to optimize the skin care effect, meet the needs of different users, and ensure the stable operation of the device.

[0363] Referring to FIGS. 25 to 27, in some embodiments, the skin care device 10 further includes a refrigeration component 300 electrically connected with the controller 400, for generating cooling energy to cool the skin when the radio frequency working module 108 and the light working module 110 are working and / or after the working ends.

[0364] In the embodiments of the present application, the refrigeration component 300 is electrically connected to the controller 400, so that the controller 400 can effectively control the refrigeration component 300. Through the electrical connection, the controller 400 can send instructions to start or stop the operation of the refrigeration component 300, and adjust the operating parameters of the refrigeration component 300, such as the refrigeration intensity.

[0365] The main function of the refrigeration component 300 is to generate cooling energy to cool the skin when the radio frequency operating module 108 and the light operating module 110 are working and / or after the work is completed, so as to cool the skin when the skin care device 10 is working and / or after the work is completed.

[0366] For example, when the radio frequency operating module 108 and the light operating module 110 are working, the skin may be heated due to the thermal effect of the radio frequency current and the thermal effect of the light irradiation. The cooling energy generated by the refrigeration component 300 can timely reduce the temperature of the skin, so as to avoid the skin from being damaged due to overheating. At the same time, the cooling energy can also relieve the discomfort of the skin during the care process, and improve the user's experience. When the radio frequency operating module 108 and the light operating module 110 are working, the cooling energy generated by the refrigeration component 300 can cool the skin in real time, so that the skin temperature is maintained within a relatively stable range.

[0367] After the radio frequency operating module 108 and the light operating module 110 are working, the cooling energy generated by the refrigeration component 300 can also continue to cool the skin, which is helpful to restore the skin to normal temperature and reduce the discomfort after the care. For example, after the light therapy is completed, the skin may be slightly heated and reddened due to the light irradiation. The cooling energy of the refrigeration component 300 can relieve this phenomenon, so that the skin can be restored to the normal state more quickly. At the same time, the cooling energy can also promote the metabolism of the skin and enhance the self-repairing ability of the skin.

[0368] Please refer to FIG. 27, in some embodiments, the skin care device 10 further comprises a transmitting element 111, which can include a blue light transmitting element 1111 or a green light transmitting element 1112.

[0370] In the embodiments of the present application, the blue light emitting element 1111 or the green light emitting element 1112 can be LED light, which is used to output corresponding blue light signals and green light signals. The blue light signals and the green light signals have specific effects in skin care. Specifically, the blue light signals generally have the effects of sterilization and anti-inflammation, and can be used to care skin diseases such as acne. The green light signals have certain effects on soothing sensitive skin and reducing redness.

[0371] The blue light emitting element 1111 or the green light emitting element 1112 is arranged between the light-transmitting piece 200 and the light emitting device 100, which can ensure that the blue light signals or the green light signals can effectively pass through the light-transmitting piece 200 to irradiate the skin. The light-transmitting piece 200 plays a role of conducting light, and can also filter and adjust the light to some extent, so that the light irradiated to the skin is more suitable for the needs of skin care.

[0372] The blue light signals or the green light signals emitted by the blue light emitting element 1111 or the green light emitting element 1112 pass through the light-transmitting piece 200 to irradiate the skin, thereby directly acting on the skin surface and the shallow tissue to play its care role. The blue light signals and the green light signals of the preset wavelength can be absorbed by different cells and tissues in the skin, thereby producing corresponding biological effects.

[0373] In the embodiments of the present application, the light emitting device 100 can include at least one halogen lamp 1001. The halogen lamp 1001 is a common light source with high brightness and stability. In the skin care device 10, the halogen lamp 1001 emits light of a preset wavelength for skin care. For example, the halogen lamp 1001 can emit light with a wavelength of 630nm-1940nm, and the light in this wavelength range has a relatively significant care effect on the skin, such as promoting cell regeneration, enhancing skin immunity, promoting collagen production, etc. The high brightness of the halogen lamp 1001 can ensure that the intensity of the light is sufficient to achieve good care effect. At the same time, the stability of the halogen lamp 1001 can also ensure the reliability of the device in the long-term use process.
