[0054] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes in different embodiments, which do not deviate from the scope of the present application, and the description and drawings in the essence are used as a description, not to limit the present application.

If the position of these elements changes, the indication of these directions also changes accordingly.

[0056] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0057] Referring to Figures 1 to 4 An embodiment of the present application provides a skin treatment device 100, which comprises a cosmetic shell 10, a temperature-controlled light-transmitting piece 20, a light-emitting element 30 and an electric heating element 40. The skin treatment device 100 can be a hair removal instrument, a radio frequency cosmetic instrument, an optical cosmetic instrument, a micro-current cosmetic instrument, etc.

[0058] Specifically, the inside of the cosmetic shell 10 is provided with a mounting space 101, and the cosmetic shell 10 is provided with a light outlet 11 communicating with the mounting space 101. The temperature-controlled light-transmitting piece 20 is arranged on the cosmetic shell 10 and at the light outlet 11, and the temperature-controlled light-transmitting piece 20 has a contact surface 201 for contacting the skin, which contacts the skin of the user to perform cold compress treatment on the cosmetic part. The light-emitting element 30 is arranged in the mounting space 101 and corresponds to the light outlet 11, and the light emitted by the light-emitting element 30 can pass through the temperature-controlled light-transmitting piece 20 and be emitted from the light outlet 11 to the cosmetic part. The electric heating element 40 is arranged on the temperature-controlled light-transmitting piece 20, and the electric heating element 40 can generate heat when powered on, and the heat can be conducted to the cosmetic part through the temperature-controlled light-transmitting piece 20.

[0059] For the skin treatment device 100 of the present application, the light emitted by the light emitting element 30 can be used for cosmetic treatment of the user's skin, such as hair removal, whitening, and spot removal, etc. In the process of cosmetic treatment, the contact surface 201 of the temperature control light-transmitting piece 20 is in contact with the user's skin to cool the skin of the cosmetic treatment site, calm the skin of the cosmetic treatment site, and inhibit skin swelling to reduce the user's pain. In addition, the electric heating element 40 provided on the temperature control light-transmitting piece 20 can generate heat, and the heat can be conducted to the skin of the cosmetic treatment site through the temperature control light-transmitting piece 20. For example, before hair removal, the skin can be heated by the electric heating element 40 to promote local blood circulation and open the pores, so that the skin and hair follicles of the cosmetic treatment site can effectively absorb the light energy of the light emitted by the light emitting element 30, thereby ensuring high-quality cosmetic results.

[0060] Further, the cosmetic shell 10 is in the shape of a water droplet, which is easy to hold and convenient for the user to hold for cosmetic treatment. In other examples, the cosmetic shell 10 can also be in the shape of a handle, a round cake, a column, etc.

[0061] The cosmetic shell 10 is internally provided with a mounting space 101, and the cosmetic shell 10 is provided with a light outlet 11 in communication with the mounting space 101. The light outlet 11 can be provided at the end of the cosmetic shell 10 or at the side of the cosmetic shell 10. The position of the light outlet 11 can be determined according to the shape of the cosmetic shell 10 and the use mode of the skin treatment device 100 as a whole.

[0062] The mounting space 101 in the cosmetic shell 10 can provide space for assembling the functional components and structural components of the skin treatment device 100. The mounting space 101 of the cosmetic shell 10 is provided with a light emitting element 30, which can emit light for cosmetic treatment. The light emitted by the light emitting element 30 can be emitted through the light outlet 11 to the cosmetic treatment site.

[0063] In some embodiments of the present application, the light emitting element 30 can be a xenon lamp. The xenon lamp utilizes the discharge phenomenon of xenon gas in a high-voltage electric field to generate ultraviolet radiation, which is then converted to visible light by fluorescent powder to irradiate the skin for improving skin problems, such as yellowing, lightening of color spots, brightening of skin color, improvement of red blood vessels, sensitive skin, rosacea, acne marks, and other skin redness problems, as well as improvement of fine lines and fine pores of the skin.

[0064] In some examples, the light emitting element 30 can also be an LED lamp that can provide high-energy light. Corresponding to the LED lamp as the light emitting element 30, an energy storage capacitor and a driving circuit can be arranged in the mounting space 101.

[0065] Specifically, the energy storage capacitor is connected with the LED lamp for providing energy required by the LED lamp for emitting high-power light. The energy storage capacitor can release electric energy to the LED lamp, so that the LED lamp generates pulsed high-power flash, thereby generating high-energy light instantaneously and irradiating the skin.

[0066] The driving circuit can include a PWM controller, an NMOS switch tube, a freewheeling diode, a choke inductor, a current feedback resistor, and a filter and voltage stabilizing capacitor.

[0067] The gate of the NMOS switch tube is electrically connected to the PWM controller, the source of the NMOS switch tube is connected to the ground through the current feedback resistor, and the source of the NMOS switch tube is connected to the feedback end of the PWM controller. The PWM controller controls the conduction or non-conduction of the NMOS switch tube, thereby controlling the conduction or non-conduction of the LED lamp loop, to achieve the control of the cosmetic light.

[0068] The PWM controller can control the frequency, brightness, pulse length, and other parameters of the LED lamp by outputting control signals with different frequencies and duty cycles, thereby achieving the adjustment of the light energy during the cosmetic treatment and hair removal. The freewheeling diode and the choke inductor form a freewheeling circuit, which provides a delay current to the LED lamp when the NMOS switch tube is turned off, thereby improving the stability and service life of the LED lamp. The filter and voltage stabilizing capacitor are connected in parallel with the LED lamp. The PWM controller and the NMOS switch tube can further include a protection circuit, which can include a resistor and a diode connected in parallel.

[0069] In this example, the light-emitting waveband of the LED lamp can be red, green, blue, yellow visible light, infrared light, near-infrared light, and the like. Among them, the waveband of the LED lamp when realizing the hair removal function is 500nm-1200nm, and the waveband of the LED lamp when realizing the cosmetic skin care function, such as generating milk light, can be 500nm-600nm, 550nm-560nm, 560nm-1200nm, 640nm-1200nm, or 900nm-1800nm, and the like.

[0070] In addition, in some examples, in addition to the above-mentioned xenon lamp tube and LED lamp, the light-emitting element 30 can also be a halogen lamp, a tungsten filament lamp, a carbon filament lamp, a heat radiation lamp, and the like.

[0071] Further, in some embodiments of the present application, a reflective cup 51 can also be arranged in the mounting space 101 of the cosmetic shell 10. The reflective cup 51 has a reflective surface, which can be a coating formed of a reflective material, and the reflective surface can reflect light.

[0072] The reflective cup 51 is arranged on the side of the light emitting element 30 away from the light outlet 11, and the reflective surface of the reflective cup 51 can reflect the light emitted by the light emitting element 30, so that the light emitted by the light emitting element 30 is effectively emitted from the light outlet 11, the light emitting rate of the light emitting element 30 is improved, the waste of light energy is avoided, and the skin treatment device 100 can efficiently perform depilation, skin care and other beauty operations.

[0073] In some embodiments of the present application, a filter 52 can also be arranged in the mounting space 101 of the beauty shell 10. The filter 52 is arranged on the side of the light emitting element 30 facing the light outlet 11, and the filter 52 can filter out unnecessary spectral components or other interfering light in the light emitted by the light emitting element 30, so that the wavelength band of the light emitted from the light outlet 11 is more suitable for the wavelength band required for depilation, beauty care and other operations.

[0074] In addition, in some embodiments of the present application, a fan 53 can also be arranged in the mounting space 101 of the beauty shell 10. The fan 53 can be arranged on the side of the reflective cup 51 away from the light outlet 11, and the fan 53 can be arranged relatively close to the light emitting element 30 in the mounting space 101.

[0075] Correspondingly, an air inlet and an air outlet can be arranged on the beauty shell 10. By arranging the fan 53, air flow in the mounting space 101 can be achieved to accelerate the dissipation of heat in the beauty shell 10, so as to avoid the situation that the skin treatment device 100 cannot be normally used due to excessive heat.

[0076] Further, in some embodiments of the present application, the skin treatment device 100 further comprises a temperature control light transmission piece 20 arranged on the beauty shell 10 and at the light outlet 11. The temperature control light transmission piece 20 has a contact surface 201 for contacting the skin, and the contact surface 201 contacts the skin of the user to perform cold compress treatment on the beauty treatment site.

[0077] The temperature control light transmission piece 20 can be sapphire. Sapphire not only has good light transmission, but also has good heat conduction performance. When sapphire is used to contact the skin, the temperature of the skin can be reduced, the skin of the user is cooled, and a cool and comfortable feeling is brought to the user.

[0078] In other examples, the temperature control light transmission piece 20 can also be a material such as pato stone, crystal, glass and the like which has good light transmission and good heat conductivity.

[0079] The temperature control light transmission piece 20 has a cuboid structure, and the light outlet 11 has a rectangular contour corresponding to the temperature control light transmission piece 20. In other examples, the temperature control light transmission piece 20 can also have a cylindrical structure, and the light outlet 11 can be circular; the temperature control light transmission piece 20 can have a triangular column structure, and the light outlet 11 can be triangular, and the like.

[0080] The end surface of the temperature-controllable light-transmitting piece 20 corresponding to the light outlet 11 is a contact surface 201, which is used to contact the skin to perform cold compress treatment on the part to be beautified. The contact surface 201 can be a flat surface or an arc surface to improve the comfort of the user using the skin treatment device 100.

[0081] In combination Figure 4 As shown in the drawings, in some embodiments of the present application, the skin treatment device 100 further comprises a refrigeration piece 54, a main control module 61 and a capacitive energy storage module 62.

[0082] The capacitive energy storage module 62 can be arranged in the beauty shell 10 and close to the side of the fan 53 away from the light outlet 11, and the capacitive energy storage module 62 is used to store and output electric energy. The main control module 61 is arranged in the interior of the beauty shell 10, and the main control module 61 is electrically connected with the light-emitting element 30 and the capacitive energy storage module 62, and the capacitive energy storage module 62 can supply power to the light-emitting element 30 through the main control module 61. The capacitive energy storage module 62 is the energy storage capacitor mentioned above when the light-emitting element 30 is an LED lamp.

[0083] The main control module 61 is electrically connected with the capacitive energy storage module 62 to control the capacitive energy storage module 62 to output the stored electric energy to the light-emitting element 30, so that the light-emitting element 30 emits light for hair removal and skin beautification and emits the light from the light outlet 11.

[0084] In some examples, the refrigeration piece 54 is a semiconductor, which can be arranged in the mounting space 101 of the beauty shell 10 and close to the light outlet 11. The refrigeration piece 54 is electrically connected with the main control module 61, so that the capacitive energy storage module 62 supplies power to the refrigeration piece 54 through the main control module 61.

[0085] The refrigeration piece 54 includes a refrigeration surface capable of generating cold and a heating surface capable of generating heat, and the refrigeration surface of the refrigeration piece 54 is connected with the temperature-controllable light-transmitting piece 20. When the refrigeration piece 54 is powered on, the cold generated by the refrigeration surface is transmitted to the temperature-controllable light-transmitting piece 20 to perform cold compress treatment on the part to be beautified through the contact surface 201.

[0086] In this example, the skin treatment device 100 can further comprise a conduction piece 55. The conduction piece 55 can be made of copper, aluminum or other materials, and the conduction piece 55 can include a conduction plate 551 and a ring-shaped conduction pipe 552.

[0087] The conduction plate 551 is arranged on the heating surface of the refrigeration piece 54, and the conduction pipe 552 is arranged on the side of the conduction plate 551 away from the refrigeration piece 54. The conduction plate 551 can transmit the heat of the refrigeration piece 54 to the conduction pipe 552, and then the heat is diffused by the conduction pipe 552, so as to avoid the heat accumulation on the refrigeration piece 54 and affect the effect of generating cold by the refrigeration piece 54.

[0088] AsFigure 2 and Figure 3 As shown in FIG. 1, the skin treatment device 100 further comprises an electric heating element 40 in some embodiments of the present application. The electric heating element 40 is arranged on the temperature-controllable light-transmitting element 20, and the electric heating element 40 can generate heat when powered on, and the heat can be conducted to the skin of the cosmetic treatment site through the temperature-controllable light-transmitting element 20.

[0089] In the present application, the electric heating element 40 can be an electric heating wire or an electric heating layer. In some examples, the electric heating wire or the electric heating layer can be arranged on the outside of the temperature-controllable light-transmitting element 20, and the electric heating wire or the electric heating layer can generate heat and transfer the heat to the temperature-controllable light-transmitting element 20 when powered on, so as to increase the temperature of the temperature-controllable light-transmitting element 20.

[0090] In some examples, the electric heating wire or the electric heating layer can be arranged inside the temperature-controllable light-transmitting element 20 and close to the outer surface of the temperature-controllable light-transmitting element 20, and the electric heating wire or the electric heating layer can generate heat and gradually increase the temperature of the temperature-controllable light-transmitting element 20 from the inside to the outside when powered on. Arranging the electric heating wire or the electric heating layer close to the outer surface of the temperature-controllable light-transmitting element 20 can avoid greatly affecting the light-transmitting property of the temperature-controllable light-transmitting element 20, so that light can be concentrated to transmit through the middle region of the temperature-controllable light-transmitting element 20, and the light-emitting rate of the light emitted from the light outlet 11 is ensured. In addition, when the electric heating element 40 is an electric heating layer, the electric heating layer can be made of a light-transmitting material to ensure its light-transmitting property.

[0091] In other examples, the electric heating wire or the electric heating layer can be arranged on the outside of the end of the temperature-controllable light-transmitting element 20 away from the contact surface 201. Such arrangement can not only ensure that the electric heating wire or the electric heating layer can effectively conduct heat to the temperature-controllable light-transmitting element 20, but also avoid affecting the cold compress function of the temperature-controllable light-transmitting element 20.

[0092] The electric heating element 40 arranged on the temperature-controllable light-transmitting element 20 can generate heat when powered on, and the heat can be conducted to the skin of the cosmetic treatment site through the temperature-controllable light-transmitting element 20. For example, the skin can be heated by the electric heating element 40 before hair removal, so as to promote the blood circulation of the local skin and open the pores, so that the skin and hair follicles of the cosmetic treatment site can effectively absorb the light energy of the light emitted by the light emitting element 30, thereby ensuring a high-quality cosmetic effect.

[0093] When the electric heating element 40 is an electric heating wire, the electric heating wire is arranged in the temperature-controllable light-transmitting element 20. When the electric heating element 40 is an electric heating layer, the electric heating layer can be an indium tin oxide conductive film glass, and the electric heating layer can be arranged on the outside of the temperature-controllable light-transmitting element 20 and close to the end away from the contact surface 201.

[0094] The electric heating element 40 is electrically connected with the main control module 61, so that the electric capacity energy storage module 62 can supply power to the electric heating element 40 through the main control module 61. The electric heating element 40 can generate heat when powered, and the heat is transmitted to the user's skin through the temperature-controlled light-transmitting element 20. When the electric heating element 40 generates heat, the temperature-controlled light-transmitting element 20 serves as a heat conduction component, so that the skin treatment device 100 has a hot compress function.

[0095] Further, referring to Figure 5 and Figure 6 In some embodiments of the present application, the temperature-controlled light-transmitting element 20 and the electric heating element 40 can be integrated into a functional module, which can be detachably mounted on the cosmetic shell 10 to realize the detachability of the temperature-controlled light-transmitting element 20 and the electric heating element 40.

[0096] When the user does not need the ice compress function, such as in cold weather or the user is not sensitive to the pain of hair removal and pays more attention to the effectiveness or time required for hair removal, the functional module can be detached from the cosmetic shell 10, and only the light-emitting element 30 is used to realize hair removal, cosmetic skin care, etc.

[0097] In this way, the loss of light emitted by the light-emitting element 30 is reduced, and the cold shrinkage effect of ice compress on the hair follicle orifice is avoided to affect the thermal decomposition effect of light on the hair follicle part, ensuring high-quality cosmetic effect.

[0098] In the present embodiment, the skin treatment device 100 further comprises a cover 70, the cover 70 is provided with a mounting opening 701 penetrating therethrough, the temperature-controlled light-transmitting element 20 is fixed in the mounting opening 701, and the contact surface 201 of the temperature-controlled light-transmitting element 20 is flush with or protrudes from the surface of the cover 70.

[0099] The cover 70 is detachably connected to the cosmetic shell 10, so that the temperature-controlled light-transmitting element 20 is detachably arranged in the light outlet 11. The temperature-controlled light-transmitting element 20 is arranged on the cover 70, and the electric heating element 40 is arranged on the temperature-controlled light-transmitting element 20. Therefore, the temperature-controlled light-transmitting element 20, the cover 70 and the electric heating element 40 integrally constitute a functional module which can be detached from the cosmetic shell 10.

[0100] In some examples, the skin treatment device 100 further comprises a first magnetic attraction element 56 and a second magnetic attraction element 57 which can be magnetically attracted. The first magnetic attraction element 56 is arranged on the cover 70, and the second magnetic attraction element 57 is arranged on the cosmetic shell 10 and close to the light outlet 11. The first magnetic attraction element 56 and the second magnetic attraction element 57 are magnetically attracted, so that the cover 70 is detachably connected to the cosmetic shell 10.

[0101] In other examples, the cover 70 and the cosmetic shell 10 can also be detachably connected through bayonet joint, threaded joint, fastener locking, etc.

[0102] In the embodiment, the cover 70 is detachably connected to the cosmetic shell 10, each cosmetic shell 10 can be configured with multiple covers 70, and the cross-sectional area of the temperature-controlled light-transmitting piece 20 on each cover 70 can be set differently. By replacing different covers 70, the adjustment of different light-emitting area sizes can be realized.

[0103] In addition, in some embodiments, the cover 70 can be an integral structure with the cosmetic shell 10, that is, the cover 70 and the cosmetic shell 10 are a structure that cannot be detached. For the skin treatment device 100 with the cover 70 and the cosmetic shell 10 being a structure that cannot be detached, the cover 70 can be directly cancelled, and the temperature-controlled light-transmitting piece 20 can be directly arranged on the cosmetic shell 10.

[0104] In the embodiment, when the electric heating element 40 is an electric heating wire, the electric heating wire is arranged in the temperature-controlled light-transmitting piece 20, and the temperature-controlled light-transmitting piece 20 is provided with an electric interface 41 corresponding to the position of the electric heating wire. When the electric heating element 40 is an electric heating layer, the electric heating layer is arranged on the surface of the temperature-controlled light-transmitting piece 20, and the electric heating layer is provided with the electric interface 41.

[0105] The skin treatment device 100 of the embodiment further comprises an electric connection terminal 58, which is arranged on the inner wall of the cosmetic shell 10 corresponding to the light-emitting port 11 and is electrically connected to the main control module 61. When the cover 70 is detachably connected to the cosmetic shell 10, the electric connection terminal 58 can be electrically connected to the electric heating element 40 through the electric interface 41, so that the electric heating element 40 is electrically connected to the main control module 61.

[0106] Further, in some embodiments of the present application, the skin treatment device 100 further comprises a skin detection sensor 731 and a skin temperature sensor 732, both of which are electrically connected to the main control module 61. The skin detection sensor 731 is used to detect the skin color of the user, and the skin temperature sensor 732 is used to measure the skin temperature of the user.

[0107] In this example, the skin detection sensor 731 can include a light emitter and a receiver. The light emitter can emit a detection light towards the skin of the user, the detection light can be reflected to the receiver through the skin of the user, the receiver receives the reflected light to form a light signal, and the receiver transmits the light signal to the main control module 61. The main control module 61 obtains the skin color signal of the user by processing the parameter signal of the detection light emitted by the light emitter and the light signal transmitted by the receiver.

[0108] The main control module 61 can control the size of the electric energy output by the capacitive energy storage module 62 to the light emitting element 30, the electric heating element 40 and / or the refrigeration element 54 according to the skin color signal, so that the cosmetic light emitted by the light emitting element 30, the heat output by the electric heating element 40 and the cold output by the refrigeration element 54 meet the cosmetic requirements of different skin colors of different users, ensuring that each user can get adaptive cosmetic care effect for his / her own skin color, greatly improving the user experience.

[0109] In this example, the skin temperature sensor 732 is used to contact the skin of the user to determine the skin temperature of the user. The skin temperature sensor 732 can transmit the determined skin temperature signal of the user to the main control module 61, and the main control module 61 can control the size of the electric energy output by the capacitive energy storage module 62 to the electric heating element 40 and / or the refrigeration element 54 according to the skin temperature signal, so that the skin temperature of the user is a constant set value.

[0110] Specifically, when the skin treatment device 100 is used for hot compress, the main control module 61 can control the capacitive energy storage module 62 to output electric energy of a set size to the electric heating element 40 according to the skin temperature signal, so that the hot compress temperature is controlled at 40℃, avoiding overheating to cause damage to the user's skin. When the skin treatment device 100 is used for cold compress, the main control module 61 can control the capacitive energy storage module 62 to output electric energy of a set size to the refrigeration element 54 according to the skin temperature signal, so that the cold compress temperature is controlled at 20℃, avoiding overcooling to cause discomfort to the user during use.

[0111] Further, as shown in Figure 7 In some embodiments of the present application, the skin detection sensor 731 and the skin temperature sensor 732 are both arranged on the cosmetic shell 10, and are both arranged on the end face of the cosmetic shell 10 provided with the light outlet 11. The skin detection sensor 731 and the skin temperature sensor 732 can be arranged on both sides of the light outlet 11 respectively. The skin detection sensor 731 and the skin temperature sensor 732 can be electrically connected with the main control module 61 through wires or electrical connection components inside the cosmetic shell 10.

[0112] In this example, the cover 70 is provided with a first opening 71 and a second opening 72 through the cover 70. The first opening 71 and the second opening 72 are arranged on both sides of the temperature control light transmission element 20 respectively.

[0113] When the cover 70 is detachably connected to the cosmetic shell 10, the skin detection sensor 731 is arranged in the first opening 71, and the skin temperature sensor 732 is arranged in the second opening 72. The end face of the skin detection sensor 731 and the end face of the skin temperature sensor 732 can both contact the skin of the user, so that the skin detection sensor 731 can detect the skin color of the user, and the skin temperature sensor 732 can determine the skin temperature of the user.

[0114] Referring to Figure 8 In some embodiments of the present application, the skin detection sensor 731 and the skin temperature sensor 732 can be both arranged on the cover 70, i.e., in this example, the temperature-controlled light-transmitting member 20, the cover 70, the electric heating member 40, and the skin detection sensor 731 and the skin temperature sensor 732 integrally constitute a functional module which can be detached from the cosmetic shell 10.

[0115] In the present embodiment, the skin treatment device 100 further comprises a first electric connection contact 741 and a first electric connection socket capable of establishing an electric connection, and a second electric connection contact 742 and a second electric connection socket capable of establishing an electric connection.

The second electric connection contact 742 is protruded on the end surface of the cosmetic shell 10 provided with the light outlet 11 and is electrically connected with the master control module 61, and the second electric connection socket is arranged on the skin temperature sensor 732.

[0117] When the cover 70 is detachably connected to the cosmetic shell 10, the first electric connection contact 741 can be docked with the first electric connection socket and an electric connection is established, and the second electric connection contact 742 can be docked with the second electric connection socket and an electric connection is established, so that the skin detection sensor 731 and the skin temperature sensor 732 are electrically connected with the master control module 61.

The second electric connection socket is arranged on the end surface of the cosmetic shell 10 provided with the light outlet 11 and is electrically connected with the master control module 61, and the second electric connection contact 742 is arranged on the skin temperature sensor 732.

[0119] When the cover 70 is detachably connected to the cosmetic shell 10, the first electric connection contact 741 can be docked with the first electric connection socket and an electric connection is established, and the second electric connection contact 742 can be docked with the second electric connection socket and an electric connection is established, so that the skin detection sensor 731 and the skin temperature sensor 732 are electrically connected with the master control module 61.

[0120] In addition, as Figure 7 shown, in some embodiments of the present application, the skin treatment device 100 can further comprise an ambient temperature sensor 733 for measuring an ambient temperature value. The ambient temperature sensor 733 is arranged on the outer surface of the cosmetic shell 10 and is electrically connected with the master control module 61.

[0121] In this embodiment, the ambient temperature sensor 733 can transmit the measured ambient temperature signal to the main control module 61, so that the main control module 61 controls the opening and closing of the electric heating element 40 and / or the temperature-controlled light-transmitting element 20 according to the ambient temperature signal.

[0122] Specifically, the main control module 61 determines whether the hot compress function or the cold compress function needs to be turned on according to the received ambient temperature signal. That is, when the ambient temperature is high, the main control module 61 determines that the hot compress function does not need to be turned on; when the ambient temperature is low, the main control module 61 determines that the cold compress function does not need to be turned on, so that the skin treatment device 100 intelligently controls different function modes according to the change of the ambient temperature.

[0123] Further, as shown in Figure 5 and Figure 9 In some embodiments of the present application, the cover 70 is detachably connected to the cosmetic shell 10, that is, the cover 70 together with the temperature-controlled light-transmitting element 20 and the electric heating element 40 can be detached from the cosmetic shell 10. In this embodiment, the skin treatment device 100 further comprises a replacement cover 80 detachably connected to the cosmetic shell 10.

[0124] Specifically, the replacement cover 80 comprises a main body part 81 and a heating wire 82 arranged inside the main body part 81, and the main body part 81 is a silica gel part, and the heating wire 82 can generate heat when powered. The silica gel material of the main body part 81 has a certain elasticity, and the contact surface 201 in contact with the user's skin can correspondingly increase or decrease according to the pressure applied by the user. In other examples, multiple replacement covers 80 can be provided, and the size of the main body part 81 in each replacement cover 80 can be different.

[0125] The main body part 81 is provided with a communication port at a position corresponding to the heating wire 82, and the skin treatment device 100 further comprises an electric connection terminal 58 arranged on the inner wall of the cosmetic shell 10 corresponding to the light outlet 11, and the electric connection terminal 58 is electrically connected to the main control module 61. When the replacement cover 80 is detachably connected to the cosmetic shell 10, the electric connection terminal 58 can be electrically connected to the heating wire 82 through the communication port, so that the heating wire 82 is electrically connected to the main control module 61.

[0126] By providing the replacement head, the setting of the electric heating element 40 on the temperature-controlled light-transmitting element 20 can be cancelled. When the hot compress function is needed, the cover 70 can be first detached from the cosmetic shell 10, and the replacement head is installed on the cosmetic shell 10, and the skin of the user is heated through the replacement head. After the hot compress is completed, the replacement head is removed, and the cover 70 is selectively installed to perform the hair removal or beauty and skin care operation.

[0127] Further, as shown in Figure 10As shown, in some embodiments of the present application, the skin treatment device 100 can further comprise a main housing 91 and a wire 92 connected between the main housing 91 and the cosmetic housing 10. The structure and related functional components of the cosmetic housing 10 have been described above and will not be repeated here.

[0128] In this embodiment, the capacitor energy storage module 62 is arranged inside the main housing 91. The light outlet 11 is formed in the side of the cosmetic housing 10, and the main control module 61 and the light emitting element 30 are arranged inside the cosmetic housing 10. One end of the wire 92 is connected to the cosmetic housing 10 and electrically connected to the main control module 61, and the other end of the wire 92 is connected to the main housing 91 and electrically connected to the capacitor energy storage module 62.

[0129] The main housing 91 and the cosmetic housing 10 are arranged independently, not only realizing the reasonable arrangement of functional components such as the main control module 61 and the capacitor energy storage module 62, but also making the cosmetic housing 10 more portable. When the user holds the cosmetic housing 10 to the part to be treated, the heat generated by the capacitor energy storage module 62 arranged inside the main housing 91 will not affect the holding of the cosmetic housing 10, reducing the phenomenon of the user's hand holding the cosmetic housing 10 being hot, and effectively improving the user's experience of using the skin treatment device 100.

[0130] For the skin treatment device of the present application, the light emitted by the light emitting element can be used for beauty care of the user's skin, such as achieving the effects of hair removal, whitening, and freckle removal, etc. In the process of beauty care, the contact surface of the temperature control light-transmitting piece contacts the user's skin to perform cold compress treatment on the part to be treated, which can calm the skin of the part to be treated and inhibit skin swelling, reducing the user's pain. In addition, the electric heating element arranged on the temperature control light-transmitting piece can generate heat, and the heat can be conducted to the skin of the part to be treated through the temperature control light-transmitting piece. For example, before hair removal, the skin can be heated by the electric heating element to promote local blood circulation and open the pores, so that the skin and hair follicles of the part to be treated can effectively absorb the light energy of the light emitted by the light emitting element, thereby ensuring high-quality beauty care.

[0131] The skin treatment device of the present application has both heating and cold compress functions, and can realize more different intelligent hair removal modes. For example, it can complete a hair removal work according to the cycle step mode of preheating, hair removal, and cold compress care, and can set the duration of each step in the cycle according to needs.
