[0027] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1 and Figure 2 The embodiment of the present application provides a skin treatment device 100, which is a device that adjusts and improves the body and skin conditions according to the physiological functions of the human body. It has the effects of whitening, skin rejuvenation, freckle removal, wrinkle removal, hair removal, etc. Based on optics, different effects can be achieved by irradiating the skin with light of special wavelengths or different types of light. For example, currently, strong pulsed light, LED light, laser, etc. are widely used.

[0030] In some embodiments, the skin treatment device 100 may be a hair removal device or a skin rejuvenation device.

[0031] In some embodiments, the skin treatment device 100 may include a host 10, which may be used to emit light. For example, the host 10 may include a light emitting head 11, which has a light emitting surface 111, and the light emitting surface 111 is used to emit care light. The light emitting head 11 may also have a cold compress surface 112, which is used to apply cold compress to the skin to reduce or even eliminate the pain or burning sensation caused by the light acting on the skin.

[0032] In some embodiments, the host 10 may be provided with a related light emitting structure and a cooling structure to achieve the light emitting and cooling effects. Figure 3 The host 10 may include a light emitting component 12, a cold compress 13, and a refrigerator 14. The light emitting component 12 is used to generate light to be directed to the skin to be treated. The cooling surface of the refrigerator 14 is thermally connected to the cold compress 13, so that the refrigerator 14 can provide cold energy to the cold compress 13, so that the cold energy generated by the refrigerator 14 can be transferred to the skin through the cold compress 13.

[0033] In some embodiments, the skin treatment device 100 can be divided into different types according to the different types of light generated by the light output component 12. For example, the light output component 12 can be used to generate laser, which is a laser light source component, and the skin treatment device 100 is a laser-type treatment device; for example, the light output component 12 can be used to generate intense pulsed light (IPL), which is an IPL light source component (such as a xenon lamp component), and the skin treatment device 100 is an intense pulsed light-type treatment device; for example, the light output component 12 can be an LED light source component.

[0034] The present application mainly uses the light emitting component 12 as an IPL light source component as an example for explanation. The light emitting principle of this type of skin treatment device 100 is: the capacitor is connected to the power supply, and the transformer component boosts the voltage to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a trigger signal, the electric energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby stimulating the lamp to instantly release strong pulsed light, thereby completing a light emission.

[0035] See also Figure 2 and Figure 3 In some embodiments, the light emitting surface 111 and the cold compress surface 112 may be the same surface; or, the light emitting surface 111 and the cold compress surface 112 may be partially the same surface, which helps to reduce the size of the light emitting head 11. For example, the cold compress 13 may be located in the optical path of the light emitted by the light emitting component 12, so that the light emitted by the light emitting component 12 passes through the cold compress 13 and is emitted to the skin to be treated. Then, the positions of the light emitting surface 111 and the cold compress surface 112 of the skin treatment device 100 are the same or partially overlapped.

[0036] In some embodiments, the light emitting surface 111 and the cold compress surface 112 may be different surfaces, or the light emitting surface 111 and the cold compress surface 112 may be adjacent or spaced apart. For example, the cold compress 13 may be located outside the optical path of the light emitted by the light emitting component 12, and the light emitted by the light emitting component 12 does not pass through the cold compress 13, then the positions of the light emitting surface 111 and the cold compress surface 112 of the skin treatment device 100 are different.

[0037] In some embodiments, the cold compress 13 may be sapphire. The cold compress 13 may be substantially in the shape of a block, a sheet, or other shapes.

[0038] In some embodiments, the cooler 14 may be a thermocouple cooler, which helps to simplify the structure of the cooler 14 and to miniaturize the cooler 14, thereby facilitating the application of the cooler 14 in locations with limited space.

[0039] In some embodiments, the refrigerator 14 may include a semiconductor refrigeration sheet. The semiconductor refrigeration sheet utilizes the Peltier effect of semiconductor materials. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple, respectively, to achieve the purpose of refrigeration. The semiconductor refrigeration sheet can be directly attached to the cold compress 13 to be thermally connected to the cold compress 13, or it can be indirectly connected to the cold compress 13 through a thermal conductive medium such as thermal grease, thereby cooling the cold compress 13.

[0040] In some embodiments, the refrigerator 14 may be a laser refrigerator, which also helps to simplify the structure of the refrigerator 14 and to miniaturize the refrigerator 14, making it easier to apply the refrigerator 14 to locations with limited space and making it less susceptible to electromagnetic influences.

[0041] In some embodiments, the skin treatment device 100 may further include an auxiliary head cover 20, and the light emitted by the host 10 can pass through the auxiliary head cover 20 and be emitted to the skin to be treated.

[0042] It is understood that the host 10 of the present application can be used alone, and the light-emitting surface 111 and the cold compress surface 112 can be attached to the skin to apply cold compress to the skin while treating the skin with light, so as to achieve freezing point skin rejuvenation or hair removal. The host 10 of the present application can also be used together with the auxiliary head cover 20.

[0043] In some embodiments, the auxiliary head cover 20 is detachably connected to the light output head 11, and the auxiliary head cover 20 is provided with a light-transmitting through hole 210, which is opposite to the light output surface 111 and the cold compress surface 112. Figure 4 As shown, the depth of the light-transmitting through hole 210 is D1, and D1 may be greater than 0 and less than or equal to 15 mm.

[0044] It can be understood that the auxiliary head cover 20 is a component that can be added when needed. For example, when acting on different parts, the auxiliary head cover 20 can be added to achieve different light output needs, and even the auxiliary head covers 20 of different specifications can be replaced; for example, when it is necessary to act on the armpits or private parts (such as hair removal), the contact area between the light head 11 and the armpits or private parts can be reduced by connecting the auxiliary head cover 20 to the light head 11, and when continuing to use it on other parts (such as the face or other parts of the body), the auxiliary head cover 20 can be removed from the light head 11 to improve the use experience. Alternatively, it is convenient for users to replace different types of auxiliary head covers 20 to adapt to the skin of corresponding parts of the body. For example, the sizes of the light-transmitting through holes 210 of different types of auxiliary head covers 20 are different to facilitate changing the light output area and light output energy.

[0045] Since the depth D1 of the light-transmitting through hole 210 can be greater than 0 and less than or equal to 15 mm, for example, the depth of the light-transmitting through hole 210 can be 15 mm, 14 mm, 13 mm, 12 mm, 11 mm, 10 mm, 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm, 1 mm or any value between any two adjacent values ​​mentioned above. In this way, when the depth of the light-transmitting through hole 210 is within the above range, it is helpful to reduce the light loss of the light emitted by the light-emitting surface 111 and ensure the cold energy transfer from the cold compress surface 112 to the skin, and it is also helpful to make the auxiliary head cover 20 not need to be provided with an overly deep light-transmitting through hole 210, which leads to an oversized size.

[0046] In some embodiments, the depth D1 of the light-transmitting through hole 210 may be greater than or equal to 2 mm and less than or equal to 10 mm. In this way, the depth of the light-transmitting through hole 210 is not too deep, and the size of the auxiliary head cover 20 does not need to be set too large, which is beneficial to reduce the light loss of the light emitted by the light-emitting surface 111 and ensure the cold energy transfer of the cold compress surface 112 to the skin. The depth of the light-transmitting through hole 210 is not too shallow to ensure the structural strength of the auxiliary head cover 20 and reduce the production cost.

[0047] In some embodiments, the light emitting area of ​​the light-transmitting through hole 210 may be less than or equal to the light emitting area of ​​the light emitting surface 111, and it can also be understood that the area of ​​the opening 2100 of the light-transmitting through hole 210 that passes through the outer surface of the light emitting head 11 is less than or equal to the area of ​​the light emitting surface 111. In this way, when the light emitting area of ​​the light-transmitting through hole 210 is less than the light emitting area of ​​the light emitting surface 111, it helps to reduce the light emitting area of ​​the skin treatment device 100, making it easier for users to care for skin in areas with smaller areas (such as eyebrows, chin, or nose, etc.). When the light emitting area of ​​the light-transmitting through hole 210 is equal to the light emitting area of ​​the light emitting surface 111, it helps to reduce the impact of the auxiliary head cover 20 on the light emitting area of ​​the light emitting surface 111, making it easier for users to care for skin in areas with larger areas (such as arms or legs, etc.).

[0048] See also Figure 2 and Figure 4 In some embodiments, the auxiliary head cover 20 may further include a light shielding portion 21, and a light-transmitting through hole 210 is provided in the light shielding portion 21, for example, the light-transmitting through hole 210 may penetrate the outer surface 211 and the inner surface 212 of the light shielding portion 21. The outer edge 213 of the light shielding portion 21 surrounds the light-transmitting through hole 210, so that other positions of the light shielding portion 21 except the light-transmitting through hole 210 can surround the light-transmitting through hole 210, which helps to reduce the amount of light leaking from the outer edge 213 of the light shielding portion 21 or reduce the intensity of the leaked light, thereby helping to reduce the impact of the leaked light on the user's eyes, and helping to improve the safety of the skin treatment device 100.

[0049] The opening 2100 of the light-transmitting through hole 210 may be disposed on the outer surface 211 of the light-shielding portion 21 .

[0050] In some embodiments, the light shielding portion 21 may be a light-proof structure. For example, positions other than the light-transmitting through hole 210 in the light shielding portion 21 may block light and prevent it from passing through, thereby reducing the amount of light leaking out.

[0051] In some embodiments, the shading portion 21 may be a low-transmittance structure, for example, the transmittance of other positions in the shading portion 21 except the light-transmitting through hole 210 is lower than the transmittance of the light-transmitting through hole 210, thereby reducing the intensity of leaked light.

[0052] In some embodiments, the outer edge 213 of the shading portion 21 can surround the projection of the light emitting surface 111 of the host 10 toward the shading portion 21, so that the shading portion 21 can better reduce the amount of light leaking from the outer edge 213 of the shading portion 21 or reduce the intensity of the leaked light.

[0053] In some embodiments, the auxiliary head cover 20 may further include a side portion 22, which is connected to the outer periphery of the light shielding portion 21, and is detachably connected to the host 10, and surrounds the light output head 11. In this way, the auxiliary head cover 20 cooperates with the light output surface 111 and the cold compress surface 112 through the light shielding portion 21, and is detachably connected to the host 10 through the side portion 22, so that the structural distribution of the auxiliary head cover 20 is more reasonable, which helps to avoid the auxiliary head cover 20 arranging a detachable connection structure adapted to the host 10 on the light shielding portion 21 and occupying the position of the light shielding portion 21, thereby helping the light shielding portion 21 to reserve more positions for arranging the light-transmitting through holes 210.

[0054] In some embodiments, the thickness of the side portion 22 can be greater than the thickness of the shading portion 21, which helps to increase the strength of the side portion 22, so that the auxiliary head cover 20 is not easily damaged or broken during repeated disassembly and connection with the main unit 10, thereby helping to increase the service life of the auxiliary head cover 20, and also facilitates the arrangement of a detachable connection structure on the side portion 22 that is adapted to the main unit 10.

[0055] In some embodiments, the inner surface of the side portion 22 may be provided with a first structure 220, and the outer surface of the light output head 11 may be provided with a second structure 113, and the first structure 220 and the second structure 113 are detachably connected. In this way, when the auxiliary head cover 20 is connected to the host 10, the first structure 220 and the second structure 113 can be covered by the auxiliary head cover 20 without being exposed, which helps to reduce the exposure of the first structure 220 and the second structure 113 and increase the overall volume of the skin treatment device 100, and also helps to improve the consistency of the appearance of the skin treatment device 100.

[0056] In some embodiments, the first structure 220 and the second structure 113 can be detachably connected in the form of a slot and a block. For example, the first structure 220 can be provided with a buckle, and the second structure 113 can be provided with a slot. For another example, the first structure 220 can be provided with a slot, and the second structure 113 can be provided with a buckle. In this way, the buckle is detachably fastened in the slot to achieve detachable connection between the first structure 220 and the second structure 113.

[0057] In the case where the first structure 220 is provided with a buckle, the buckle also helps to increase the wall thickness of the side portion 22 at the buckle, thereby helping to improve the strength and rigidity of the structure around the buckle in the side portion 22 without increasing the overall thickness of the side portion 22. The buckle and the side portion 22 can be an integrally formed structure.

[0058] In some embodiments, the first structure 220 and the second structure 113 can be detachably connected by magnetic attraction. For example, the first structure 220 can be a magnet, and the second structure 113 can be a magnetic attraction member or a magnet. For another example, the first structure 220 can be a magnetic attraction member or a magnet, and the second structure 113 can be a magnet. In this way, the magnetic attraction of the magnet and the magnet or the magnetic attraction member cooperates to achieve a detachable connection between the first structure 220 and the second structure 113.

[0059] See also Figure 5 In some embodiments, the light-transmitting through hole 210 may be provided with first structures 220 at opposite ends along the length direction X of the auxiliary head cover 20, the number of the second structures 113 is the same as the number of the first structures 220, and each first structure 220 is detachably connected to a corresponding second structure 113. In this way, it is helpful to improve the stability of the connection between the auxiliary head cover 20 and the host 10, so that the two ends of the auxiliary head cover 20 in the length direction X are not easy to be easily lifted off the host 10 due to excessive length.

[0060] In some embodiments, the light-transmitting through hole 210 may be provided with a first structure 220 at one end along the length direction X of the auxiliary head cover 20 , which helps to reduce the number of arranged first structures 220 and helps to simplify the structure of the auxiliary head cover 20 .

[0061] See also Figure 6 In some embodiments, the auxiliary head cover 20 may further include a light-transmitting heat-conducting plate 23, that is, a light-transmitting heat-conducting plate 23 is provided in the light-transmitting through hole 210, or a light-transmitting heat-conducting plate 23 is provided on the inner side of the light-transmitting through hole 210, so as to further reduce the contact area between the light output head 11 and the skin, which is more suitable for use when caring for the skin of the armpits or private parts.

[0062] See also Figure 6Specifically, the light-transmitting heat-conducting plate 23 is connected to the light-shielding portion 21 and is opposite to the light-transmitting through hole 210. The light-transmitting heat-conducting plate 23 covers the light-emitting surface 111 and the cold compress surface 112 and contacts the cold compress surface 112. In this way, the light-transmitting heat-conducting plate 23 can separate the user's skin from the light-emitting surface 111 and the cold compress surface 112, so that the user only needs to clean the auxiliary head cover 20 after using the skin treatment device 100 for care, without having to clean the light-emitting surface 111 and the cold compress surface 112, which helps to reduce the cleaning burden of the user after using the skin treatment device 100 for care. In addition, when the user uses the skin treatment device 100 to care for the armpits, face and other parts, since the light-transmitting heat-conducting plate 23 separates the user's skin from the light-emitting surface 111 and the cold compress surface 112, after the user cares for the armpit skin, the user can remove the auxiliary head cover 20, or replace different types of auxiliary head covers 20 to care for other parts of the skin such as the face, which can reduce the user's discomfort and improve the user experience.

[0063] In some embodiments, the light-transmitting heat-conducting plate 23 can be at least partially located in the light-transmitting through hole 210, and the light-transmitting heat-conducting plate 23 can be connected to the wall surface of the light-shielding portion 21 that surrounds the light-transmitting through hole 210. For example, the light-transmitting heat-conducting plate 23 can be bonded or clamped to the wall surface of the light-shielding portion 21 that surrounds the light-transmitting through hole 210.

[0064] In some embodiments, the light-transmitting heat-conducting plate 23 may be a sheet-like film structure to be attached to the inner side of the light-shielding portion 21 and the light-transmitting through hole 210 .

[0065] In some embodiments, Figure 7 As shown, the surface 231 of the light-transmitting heat-conducting plate 23 facing away from the light-emitting surface 111 or the cold compress surface 112 can be flush with the outer surface 211 of the shading portion 21 , which helps to maintain the consistency of the appearance of the auxiliary head cover 20 .

[0066] See also Figure 6 In some embodiments, a surface 231 of the light-transmitting heat-conducting plate 23 that faces away from the light-emitting surface 111 or the cold compress surface 112 can be located in the light-transmitting through hole 210, so that a certain distance exists between the surface 231 of the light-transmitting heat-conducting plate 23 and the outer surface 211 of the light-shielding portion 21, thereby helping the skin to sink into the light-transmitting through hole 210.

[0067] In some embodiments, the distance between the surface 231 of the transparent heat conductive plate 23 and the outer surface 211 of the shading portion 21 is D2, and D2 can be greater than 0 and less than or equal to 15 mm. For example, the distance between the transparent heat conductive plate 23 and the outer surface 211 of the shading portion 21 can be 15 mm, 14 mm, 13 mm, 12 mm, 11 mm, 10 mm, 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm, 1 mm or any value between any two adjacent values ​​mentioned above. In this way, when the distance between the light-transmitting heat-conducting plate 23 and the outer surface 211 of the light-shielding portion 21 is within the above-mentioned range, it helps to reduce the light loss of the light emitted from the light-emitting surface 111 and ensure the transfer of cold energy from the cold compress surface 112 to the skin, and it also helps to ensure that the user's skin is sunken into the light-transmitting through hole 210 and contacts the light-transmitting heat-conducting plate 23 to increase the relative area of ​​the skin to the light-emitting surface 111 and the cold compress surface 112, and at the same time, the distance between the light-transmitting heat-conducting plate 23 and the outer surface 211 of the light-shielding portion 21 will not be too large to cause the overall size of the auxiliary head cover 20 to be too large.

[0068] In some embodiments, the distance D2 between the surface 231 of the light-transmitting heat-conducting plate 23 and the outer surface 211 of the light-shielding portion 21 can be greater than or equal to 2 mm and less than or equal to 10 mm. In this way, the distance between the light-transmitting heat-conducting plate 23 and the outer surface 211 is not too large, and the size of the auxiliary head cover 20 does not need to be set too large, which is beneficial to reduce the light loss of the light emitted by the light-emitting surface 111 and ensure the cold energy transfer from the cold compress surface 112 to the skin. The distance between the light-transmitting heat-conducting plate 23 and the outer surface 211 is not too small, so that the user's skin can better sink into the light-transmitting through hole 210, so as to better increase the area of ​​the skin relative to the light-emitting surface 111 and the cold compress surface 112.

[0069] In some embodiments, the auxiliary head cover 20 may not include the light-transmitting heat-conducting plate 23. In this way, when the auxiliary head cover 20 is used, the skin can be sunken into the light-transmitting through hole 210 and contact the light-emitting surface 111 and the cold compress surface 112 of the host 10 to ensure that the skin is in contact with the light-emitting surface 111 and the cold compress surface 112, which helps to ensure that the cold compress surface 112 transfers cold energy to the skin, and also helps to make the light emitted from the light-emitting surface 111 act directly on the skin with less light loss, so that even if the auxiliary head cover 20 is used, the light treatment and cold compress functions of the skin treatment device 100 are not affected or are basically not affected. Compared with the auxiliary head cover 20 with the light-transmitting heat-conducting plate 23, the auxiliary head cover 20 without the light-transmitting heat-conducting plate 23 can be more conducive to reducing energy loss to ensure the cold compress effect and light treatment effect.

[0070] It can be understood that for the auxiliary head cover 20 with the light-transmitting heat-conducting plate 23, the light-emitting area of ​​the light-transmitting through hole 210 can be made equal to the light-emitting area of ​​the light-emitting surface 111 to minimize the light energy loss. For the auxiliary head cover 20 without the light-transmitting heat-conducting plate 23, the light-emitting area of ​​the light-transmitting through hole 210 can be made smaller than the light-emitting area of ​​the light-emitting surface 111 to be suitable for use scenarios where the light processing area needs to be changed.

[0071] In some embodiments, the skin treatment device 100 may further include a reflective layer, which may be disposed on the inner surface of the auxiliary head cover 20. The reflective layer helps to reflect the light emitted from the light-emitting surface 111, and helps to allow more light to be emitted from the light-transmitting through hole 210 to the user's skin, thereby helping to reduce the light loss of the light-emitting surface 111. In addition, the reflective layer also helps to reduce the amount of light leaking from the auxiliary head cover 20.

[0072] In some embodiments, the reflective layer may be provided on at least one of the inner surface 212 of the light shielding portion 21 and the inner surface of the side portion 22. For example, the reflective layer may be provided on the inner surface 212 of the light shielding portion 21. For another example, the reflective layer may be provided on the inner surface of the side portion 22. For another example, the reflective layer may be provided on the inner surface 212 of the light shielding portion 21 and the inner surface of the side portion 22.

[0073] In some embodiments, the reflective layer can be sprayed on the inner surface of the auxiliary head cover 20 , or the reflective layer can be plated on the inner surface of the auxiliary head cover 20 .

[0074] In some embodiments, the skin treatment device 100 includes at least two auxiliary head covers 20, at least one of which is provided with a light-transmitting heat-conducting plate 23, and at least one of which is not provided with a light-transmitting heat-conducting plate 23, so as to be suitable for different usage scenarios, thereby improving the user's flexibility of use. For example, when treating regular parts of the skin such as the face, arms, and legs, the auxiliary head cover 20 may not be used; when light treatment is required for the armpits, private parts, etc., the auxiliary head cover 20 with a light-transmitting heat-conducting plate 23 may be used to separate the skin from the host 10; when the skin of a local protruding part (such as the brow, chin, or nose) needs to be treated, the auxiliary head cover 20 without a light-transmitting heat-conducting plate 23 may be used.
