[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0046] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0047] The skin care device provided in the embodiment of the present application is mainly used for caring for the skin, which may be the skin on the face, the hands, the legs, the abdomen, or other parts of the human body.

[0048] Skin care devices include, but are not limited to, phototherapy devices, microcurrent devices, and radiofrequency devices. Phototherapy devices primarily utilize specific wavelengths of light, such as intense pulsed light and lasers, to improve skin conditions. These wavelengths can penetrate the skin's surface, reaching varying depths and affecting pigments, blood vessels, collagen, and other components. When using these devices for phototherapy, their light-emitting components generate significant heat, potentially causing burns when the devices come into contact with the user's skin.

[0049] To reduce or even eliminate the burning or painful sensation caused by light therapy skin care devices, please refer to Figures 1 to 3 An embodiment of the present application provides a skin care device 100, including a shell 1, a light-transmitting skin-contacting member 2, a light-emitting device 9 and at least one cooling member 4. The shell 1 is provided with an inner cavity 6 and an opening 11 connected to the inner cavity 6; the light-transmitting skin-contacting member 2 is installed in the opening 11; the light-emitting device 9 is arranged in the inner cavity 6 and irradiates light toward the light-transmitting skin-contacting member 2 to care for the skin through the light-transmitting skin-contacting member 2; at least one cooling member 4 is installed in the inner cavity 6 for cooling the light-transmitting skin-contacting member 2.

[0050] In this embodiment, the housing 1 of the skin care device 100 is primarily used for user gripping and provides a mounting location for other components. To facilitate gripping, the housing 1 can be designed into an ergonomic shape, such as a streamlined shape or a handle with a non-slip design, to enhance grip comfort and stability.

[0051] The material of the housing 1 can be selected based on different needs. For example, to reduce the overall weight, a lightweight, high-strength material such as carbon fiber or aluminum alloy can be used. Considering the user's grip comfort, the surface of the housing 1 can be made of a soft-touch material such as silicone or polyurethane coating. These materials not only provide a soft touch, but also can increase the anti-slip effect through surface treatment processes (such as spraying, plating, or rubber coating), thereby improving the user experience of the device.

[0052] In this embodiment, the cooling element 4 includes a cold surface. When powered, the cooling element 4 generates a low temperature on the cold surface. This cold surface contacts the light-transmitting skin-applying element 2, thereby continuously cooling the light-transmitting skin-applying element 2. The light-transmitting skin-applying element 2, in turn, cools the skin surface by directly contacting the skin, making it feel cool. This can alleviate or even eliminate the burning or pain caused by the skin's heating. Therefore, the skin care device 100 in this embodiment of the present application has a cold compress function, which can reduce the probability of the skin care device 100 easily burning the user's skin during treatment.

[0053] In some embodiments, cooling element 4 is a semiconductor refrigeration chip. When powered, the semiconductor refrigeration chip absorbs heat from the cold end and releases heat from the hot end. For example, the semiconductor refrigeration chip is a thermocouple structure composed of an N-type semiconductor material and a P-type semiconductor material. Because the semiconductor refrigeration chip has no mechanical moving parts during the cooling process, it is very quiet and wear-free during operation, and has high reliability. Moreover, the semiconductor refrigeration chip is small and lightweight, making it suitable for integration into space-constrained devices, particularly handheld or portable devices.

[0054] It should be noted that the principle of semiconductor cooling element 4 is prior art and will not be elaborated here. The shape of cooling element 4 is not specifically limited here. Of course, in other embodiments, cooling element 4 can also be a liquid-cooled radiator, where the liquid transfers heat during circulation, which is not limited in this embodiment of the present application.

[0055] In this embodiment, the light-transmitting skin-applicable member 2 can be made of a transparent material to facilitate the transmission of light emitted by the light-emitting device 9. For example, it can be made of a transparent polymer material or a transparent inorganic material. Transparent polymer materials can be PC, transparent ABS, etc.; transparent inorganic materials can be glass, sapphire, ruby, diamond, etc.

[0056] As a preferred embodiment of the present application, the light-transmitting skin-applying member 2 is made of sapphire, which has excellent light transmission and thermal conductivity. The low temperature transmitted by the cooling element 4 quickly cools the skin surface, preventing the skin from being stimulated by excessive temperatures, thereby making the use of the skin care device 100 more comfortable. Furthermore, sapphire has high hardness and good wear resistance, effectively protecting the skin from damage during use.

[0057] As an embodiment, the skin care device 100 is a beauty instrument, and the light-emitting device 9 includes at least one halogen lamp, which is used to output near-infrared light with a wavelength of 760-1940nm to the skin through the light-transmitting skin-adhesive member 2. When the near-infrared light acts on the skin, it can stimulate the synthesis of fibroblasts, and fibroblasts are the main producers of collagen. Therefore, it can promote the production of collagen and enhance skin thickness. In addition, it can promote the reproduction of keratinocytes, accelerate keratin formation, and restore the skin barrier. In specific applications, as an alternative embodiment, the skin care device 100 can also be a hair removal device, etc., which is not limited in this embodiment of the present application.

[0058] In addition, the light emitting device 9 can also use light sources such as LED and laser diode, and different wavelengths of light can be selected according to specific nursing needs, which is not limited in the embodiments of the present application.

[0059] The light-transmitting skin-contacting member 2 includes a first end face 212 facing the light-emitting device 9 and a second end face 211 opposite to the first end face 212 and exposed to the housing 1. At least one cooling member 4 is opposite to at least a portion of the first end face 212 and is thermally connected thereto.

[0060] like Figure 4 As shown, the existing cooling components 4 are usually distributed on the peripheral side of the light-transmitting skin-contacting component 2. Since a good cooling effect needs to be ensured, the cooling components 4 usually have a certain width. Therefore, when the cooling components 4 are arranged on the peripheral side of the light-transmitting skin-contacting component 2, the thickness of the light-transmitting skin-contacting component 2 needs to be increased accordingly to fully fit the cooling components 4, resulting in a larger thickness and volume of the light-transmitting skin-contacting component 2, a higher cost, and a smaller light-emitting surface of the light-transmitting skin-contacting component 2 and a larger width of the shell in which the light-transmitting skin-contacting component 2 is located.

[0061] To solve the above problems, please refer to Figure 5 and Figure 6 In one embodiment of the present application, at least one cooling element 4 is opposite to and thermally connected to at least a portion of the first end surface 212. That is, the cooling element 4 is arranged on the back of the light-transmitting skin-applying member 2. Compared with the related art in which the cooling element 4 is arranged on the peripheral side of the light-transmitting skin-applying member 2, the embodiment of the present application can achieve full contact between the cooling element 4 and the light-transmitting skin-applying member 2 without increasing the thickness of the light-transmitting skin-applying member 2, so that the thickness and volume of the light-transmitting skin-applying member 2 can be made smaller, thereby reducing the production cost of the light-transmitting skin-applying member 2. In addition, arranging the cooling element 4 on the back of the light-transmitting skin-applying member 2 utilizes the space in the longitudinal direction of the shell 1 and does not affect the light-emitting surface of the light-transmitting skin-applying member 2. When the surface width of the shell 1 where the light-transmitting skin-applying member 2 is located is limited, the light-emitting surface of the light-transmitting skin-applying member 2 can be made larger, so as to improve the care effect of the skin care device 100.

[0062] Please continue to refer to Figure 6In some embodiments, the light-transmitting skin-contacting member 2 includes a light-transmitting member main body 21 and an annular flange 22. The light-transmitting member main body 21 is at least partially embedded in the opening 11, and the annular flange 22 is protruded from the outer periphery of the light-transmitting member main body 21 and abuts against the edge of the opening 11, so that the light-transmitting skin-contacting member 2 can be firmly installed at the opening 11, and the light-transmitting member main body 21 can fit the human skin for skin care; wherein, at least one cooling member 4 is at least partially opposite to and thermally connected to the side surface of the annular flange 22 facing the light-emitting device 9, avoiding the area of ​​the light-transmitting skin-contacting member 2 facing the light-emitting device 9, while not affecting the phototherapy function of the skin care device 100, it can also cool the light-transmitting skin-contacting member 2 so that the skin care device 100 has a cold compress function.

[0063] Please refer to Figure 7 In some embodiments, the annular flange 22 is flush with the surface of the light-transmitting member main body 21 facing the light-emitting device 9 .

[0064] It should be noted that the flushness here may also mean approximately flushness, for example, there is a distance of ±1 mm between the annular flange 22 and the surface of the light-transmitting member main body 21 facing the light-emitting device 9 .

[0065] In this embodiment, the annular flange 22 is flush with the surface of the side of the light-transmitting member main body 21 facing the light-emitting device 9. The annular flange 22 can abut the edge of the opening 11, so that the light-transmitting skin-adhering member 2 can be firmly installed at the opening 11, preventing the entire light-transmitting skin-adhering member 2 from easily falling off from the opening 11, thereby improving the installation stability of the light-transmitting skin-adhering member 2.

[0066] Please refer to Figure 8 In another embodiment, the annular flange 22 is flush with the surface of the light-transmitting member main body 21 on the side facing away from the light-emitting device 9 .

[0067] It should be noted that the flushness here may also mean approximately flushness, for example, there is a distance of ±1 mm between the annular flange 22 and the surface of the side of the light-transmitting member main body 21 facing away from the light-emitting device 9 .

[0068] In this embodiment, the annular flange 22 is flush with the surface of the side of the light-transmitting member main body 21 facing away from the light-emitting device 9, which can maximize the area of ​​the second end face 211, thereby increasing the area of ​​contact between the light-transmitting skin-contacting member 2 and the user, improving the phototherapy effect and the cold compress effect, and further improving the care effect of the skin care device 100.

[0069] In some embodiments, please refer to Figure 5 and Figure 6 The annular flange 22 is annularly arranged on the periphery of the light-transmitting member 21. The light-transmitting member 21 passes through the opening 11 of the housing 1, and the annular flange 22 abuts against the edge of the opening 11, so that the light-transmitting skin-contacting member 2 can be firmly embedded in the opening 11 to contact the human skin for skin care.

[0070] Of course, the shape design of the annular flange 22 can also be determined according to specific needs, and the embodiment of the present application is not limited here.

[0071] In some embodiments, the second end surface 211 is a polygon with more than four sides, and the opening 11 is a corresponding polygon with more than four sides. Specifically, there are many options for the shape design of the second end surface 211.

[0072] In a possible embodiment, the second end surface 211 is octagonal, such as Figure 6 As shown, correspondingly, the opening 11 is also designed to be octagonal to facilitate the installation of the light-transmitting skin-adhesive component 2 on the housing 1.

[0073] Compared to the circular design of the light-transmitting skin-applying member 2 in the related art, the light-transmitting skin-applying member 2 provided in the present embodiment has an octagonal second end surface 211, which can provide care for relatively narrow areas of the human body, such as the nose. Moreover, compared to quadrilateral or triangular shapes, the octagonal second end surface 211 in the present embodiment has a better fit for smoother areas of the skin. Therefore, the octagonal design of the second end surface 211 can not only provide care for narrow areas of human skin, but also maximize the area of ​​fit, thereby achieving a better care effect for the skin care device 100 provided in the present embodiment.

[0074] Of course, in other embodiments, the second end face 211 may also be a pentagon, a hexagon, or a polygon with a higher number of sides, and the opening 11 may correspondingly be a pentagon, a hexagon, or a polygon with a higher number of sides, which is not limited in the embodiments of the present application.

[0075] In some embodiments, please refer to Figure 6 The skin care device 100 further includes a cooling member 5 , and opposite sides of the cooling member 5 are respectively in contact with the cooling member 4 and the annular flange 22 .

[0076] In this embodiment, one side of the cooling member 5 is bonded to the cold surface of the refrigeration member 4, and the other side is bonded to the annular flange 22, which can transfer the low temperature generated by the refrigeration member 4 to the light-transmitting skin-contacting member 2, and can reduce the gap between the refrigeration member 4 and the light-transmitting skin-contacting member 2, thereby preventing the refrigeration member 4 from bumping into and damaging the light-transmitting skin-contacting member 2.

[0077] In this embodiment, the cooling member 5 can be made of materials with excellent thermal conductivity, such as graphene, thermal silica gel, thermal silicone film, flexible thermal pad, etc., and can be selected and set according to specific applications. This embodiment of the application is not limited here.

[0078] In some embodiments, please refer to Figure 5 、 Figure 7 and Figure 8The number of the refrigeration components 4 is at least two, and the at least two refrigeration components 4 are distributed at intervals along the circumference of the opening 11 and are respectively thermally connected to the annular flange 22 .

[0079] For example, there are two cooling components 4 in the embodiment of the present application, which are respectively arranged on opposite sides of the opening 11. The two cooling components 4 are used to cool the light-transmitting skin-contacting component 2 at the same time, thereby enhancing the heat conduction efficiency and making the cooling effect more significant, thereby being able to quickly reduce the temperature of the entire light-transmitting skin-contacting component 2, further enhancing the cold compress effect of the light-transmitting skin-contacting component 2, reducing or even eliminating the pain felt by the user when caring for the skin, and improving the user experience.

[0080] Of course, in other embodiments, there may be three or more refrigeration components 4, and the positions of the multiple refrigeration components 4 may be specifically set according to actual conditions, which is not limited in the embodiment of the present application.

[0081] In order to ensure that the light-transmitting skin-adhesive component 2 and the cooling component 4 can be firmly installed in the skin care device 100, please refer to Figure 9 and Figure 10 The skin care device 100 provided in the embodiment of the present application further includes a mounting bracket 3 , which is disposed in the inner cavity 6 and is used to fix the light-transmitting skin-adhesive member 2 to the outer shell 1 .

[0082] Among them, the mounting frame 3 is provided with a light-through hole 31 and at least one avoidance hole 32. The light-through hole 31 is arranged opposite to the opening 11 to allow the light emitted by the light-emitting device 9 to pass through and illuminate the light-transmitting skin-attached component 2, so as to prevent the mounting frame 3 from blocking the light of the light-emitting device 9; the avoidance hole 32 is used for the cooling component 4 to pass through to connect the light-transmitting skin-attached component 2 for thermal conductivity, thereby limiting the left and right movement of the cooling component 4. At the same time, the cooling component 4 is installed in the mounting frame 3 to minimize the volume occupied between the two, so that the thickness can be made smaller.

[0083] In some embodiments, the first end surface 212 includes a light-transmitting area 2121 and a light-impermeable area 2122 , the light-impermeable area 2122 is located outside the light-transmitting area 2121 , and at least one cooling element 4 is opposite to and thermally connected to at least a portion of the light-impermeable area 2122 .

[0084] In this embodiment, the first end surface 212 is further divided into a light-transmitting area 2121 and a non-light-transmitting area 2122, wherein the light-transmitting area 2121 is used to allow the light emitted by the light-emitting device 9 to pass smoothly, and the non-light-transmitting area 2122 is located outside the light-transmitting area 2121 and is used for functional connection with other components (specifically, providing an installation area for the refrigeration component 4).

[0085] When the user uses the skin care device 100, the light emitted by the light-emitting device 9 passes through the light-transmitting area 2121 through the light-through hole 31 and irradiates the skin to perform phototherapy care on the skin. The cooling element 4 is arranged in the non-light-transmitting area 2122, which can prevent the cooling element 4 from blocking the light and affecting the phototherapy effect, and can also prevent the cooling element 4 from being exposed from the second end surface 211.

[0086] In some embodiments, please refer to Figure 6 The light-transmitting skin-contacting component 2 also includes a light-shielding layer, which is arranged on at least a portion of the first end surface 212 and is arranged opposite to at least one refrigeration component 4. The area of ​​the light-shielding layer is greater than or equal to the positive projection area of ​​at least one refrigeration component 4 on the first end surface 212, that is, the light-shielding layer can always block the refrigeration component 4.

[0087] Among them, the shading layer forms a non-light-transmitting area 2122, which not only prevents the refrigeration component 4 from being seen from the second end surface 211, but also blocks the image of the mounting bracket 3 on the second end surface 211, thereby improving the user's visual experience; the first end surface 212 faces the side of the light-emitting device 9 and the area opposite the opening 11 forms at least a partial light-transmitting area 2121, ensuring that the light emitted by the light-emitting device 9 can be irradiated to the skin through the light-transmitting skin-adhesive component 2.

[0088] In some embodiments, the light-shielding layer includes a silver coating. Silver is a lustrous and decorative metal. By coating the non-transparent area 2122 with silver, components within the inner cavity 6 can be shielded, preventing visibility of components such as the cooling element 4, resulting in an aesthetically pleasing appearance. Silver also has excellent thermal conductivity. When the cooling element 4 is cooling, the silver coating can transfer more heat to the light-transmitting skin-applying component 2, thereby enhancing the cooling effect of the light-transmitting skin-applying component 2.

[0089] In another embodiment, the light-shielding layer may also include an ink layer, and the ink layer may be formed into various patterns, which can shield the components of the inner cavity 6 while increasing the aesthetic appearance of the light-transmitting skin-attaching component 2.

[0090] Of course, in other embodiments, the light-shielding layer may also include a silver-plated layer and an ink layer at the same time, and the silver-plated layer is located between the first end surface 212 and the ink layer, further enhancing the appearance of the light-transmitting skin-attaching component 2.

[0091] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the skin care device 100 further includes an annular reflector 14, which is disposed between the light-transmitting skin-attached component 2 and the light-emitting device 9. The annular reflector 14 encloses a hollow inner hole, which is used for allowing light emitted by the light-emitting device 9 to pass through and illuminate the light-transmitting skin-attached component 2.

[0092] In this embodiment, the inner reflective surface of the annular reflector 14 can be processed into a mirror surface as required to achieve a higher reflectivity. Alternatively, the inner reflective surface can be coated with a reflective material, such as aluminum plating, silver coating, or other high-reflectivity coating, to further enhance the light reflection effect. Through these measures, the annular reflector 14 can maximize the retention of light emitted by the light-emitting device 9, ensuring full utilization of the light energy.

[0093] As for the material selection of the annular reflector 14, metal materials such as aluminum or stainless steel can be used, which not only have good reflective properties, but also have durability and heat dissipation properties. Alternatively, the annular reflector 14 can also be made of a plastic material with high reflectivity, which can reduce the weight of the entire device while ensuring the reflective effect.

[0094] This embodiment effectively reduces light loss by introducing an annular reflector 14, ensuring that light from the halogen lamp can penetrate the light-transmitting skin-applying member 2 to the greatest extent possible, achieving a better phototherapy effect. This design not only improves the device's light efficacy but also enhances the user experience, making the light therapy and cold compress effects more effective.

[0095] Please continue to refer to Figure 6 In some embodiments, the skin care device 100 further includes a light-transmitting seal 8 , which is disposed on a side of the annular reflector 14 away from the light-emitting device 9 , and a closed cavity 13 is formed between the light-transmitting seal 8 and at least a portion of the first end face 212 .

[0096] In this embodiment, the light-transmitting skin-contacting member 2 is made of sapphire. It has two main surfaces: the hot side (first end face) facing the light-emitting device 9, and the cold side (second end face) contacting the user's skin. The hot side of the sapphire faces the light-emitting device 9. During device operation, this side receives the high-intensity light emitted by the light source. Due to continuous contact with the light source, the hot side absorbs a certain amount of heat, resulting in a higher temperature.

[0097] The fundamental cause of fogging is high humidity. When the hot surface comes into contact with the outside air, the temperature difference causes moisture in the air to condense on the hot surface, forming fog. This affects the light transmittance of the light-transmitting skin-applied component 2 and the overall performance of the device. To prevent fogging of the hot surface of the sapphire due to temperature differences, a light-transmitting seal 8 is used in this embodiment to prevent this fogging.

[0098] Specifically, the light-transmitting seal 8 isolates the sapphire's hot surface from the outside air, preventing moisture from directly contacting the hot surface. When the light-emitting device 9 emits light, the light-transmitting seal 8 ensures that the sapphire's hot surface remains dry, preventing condensation from forming and contacting the hot surface due to temperature differences. This effectively prevents fogging and maintains stable light output and efficient transmission.

[0099] Furthermore, the light-transmitting seal 8 forms a closed cavity 13 with the light-transmitting skin-applicable member 2 through the sealing ring 12. The inner ring of the sealing ring 12 is provided with an annular groove along the circumference for assembling the light-transmitting seal 8, which is convenient for installation and removal and has a good sealing effect.

[0100] In this embodiment, the light-transmitting seal 8 can be made of white glass, which has excellent high-temperature resistance and light-transmitting properties, ensuring the transmission of light from the light-emitting device 9 and preventing fogging of the light-transmitting skin-applicable member 2. Of course, the light-transmitting seal 8 can also be made of other materials with similar properties, such as quartz glass or high-temperature resistant ceramics, which also have excellent light transmittance and heat resistance.

[0101] To further enhance the fog prevention effect, the sealed chamber 13 can be vacuumed. This effectively reduces the air content within the sealed chamber 13, thereby lowering the humidity and further preventing fogging on the sapphire's hot surface caused by temperature differences. This treatment protects the sapphire's optical properties.

[0102] In some embodiments, the skin care device 100 also includes a plurality of electrodes 7, which are arranged at one end of the shell 1 having an opening 11, and the plurality of electrodes 7 are at least partially exposed to the shell 1, and the plurality of electrodes 7 are distributed around the periphery of the light-transmitting skin-adhesive component 2 for outputting microcurrent and / or radiofrequency current to the skin.

[0103] In this embodiment, multiple electrodes 7 can output microcurrent to the skin. Microcurrent can stimulate muscle fiber contraction, increase muscle tension, and enhance muscle strength and firmness. At the same time, current stimulation of the dermis will also promote cells to produce more adenosine triphosphate (ATP), and ATP is a key substance for collagen production. Therefore, microcurrent massage of the skin can accelerate the production of collagen, thereby achieving the effect of firming, lifting and slimming the face.

[0104] In this embodiment, multiple electrodes 7 can output radio frequency current to the skin. The thermoelectric effect of the radio frequency current heats the skin to intensify the irregular movement of the active ingredients in the beauty product and form aqueous channels in the stratum corneum, which can help promote the skin's absorption of beauty products or medical products.

[0105] It should be noted that the microcurrent output by electrode 7 is an alternating current greater than 0uA and less than or equal to 1000uA. Microcurrent is a current at the microampere (i.e., uA) level, which is close to the natural bioelectricity of the human body. The safe limit of current acceptable to the human body is 50mA, while the microcurrent of the skin care device 100 provided in this embodiment is far below the limit required by the safety standard, fully ensuring the safety and reliability of the product; the frequency of the radio frequency current is 300K-300MHz, which generates heat when passing through the skin tissue. The heat denatures and shrinks the collagen in the dermis. The natural wound healing reaction triggers the formation of new collagen and further skin contraction, which has a tightening and lifting effect on the skin.

[0106] It should be noted that the multiple electrodes 7 are at least partially exposed to the shell 1, which may include the case where the electrode 7 is protruding from the shell 1, the case where the electrode 7 is flush with the surface of the shell 1, or the case where the electrode 7 is recessed at a certain distance from the surface of the shell 1. The purpose is to enable the electrode 7 to output microcurrent and / or radiofrequency current to the skin during the contact between the electrode 7 and the skin.

All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
