Description

Technical Field

[0001] The present invention relates to the technical field of beauty equipment, and in particular to a skin treatment device. Background Art

[0002] With the improvement of the quality of life, people pay more and more attention to the care and maintenance of the skin. At present, the commonly used beauty instruments on the market mainly include hair removal instruments, IPL skin rejuvenation instruments, milk light skin beautification instruments and so on.

[0003] Among them, the hair removal device is based on the principle of selective photothermal dynamics and utilizes the "selective photothermal effect" of light. It uses light adjusted to a specific wavelength to pass through the epidermis and directly irradiate the hair follicles. The melanin in the hair follicles and hair shafts selectively absorbs light energy. The resulting thermal effect causes the hair follicles to necrotize, and the hair no longer grows.

[0004] The Milk Light Skin Beautifying Device effectively promotes skin metabolism and collagen production through the thermal effect of phototherapy, giving users healthier and younger skin. The Milk Light Skin Beautifying Device is particularly outstanding in improving skin radiance, firmness and elasticity.

[0005] However, hair removal devices and milk light skin beautification devices will inevitably cause the skin temperature to rise when in use, causing the user to experience a burning sensation. In order to improve the user experience, beauty devices usually use cold compress components to cool the skin, but the temperature reduction will affect the effects of hair removal, skin beautification and other care, resulting in the beauty device being unable to have both good beauty effects and high comfort.

[0056] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0057] See also Figures 1 to 4 In one embodiment of the present application, a skin treatment device 100 is provided, which includes a beauty housing 10, a temperature-controlled light-transmitting member 20, a light-emitting element 30, and an electric heating member 40. The skin treatment device 100 can be a hair removal device, a radio frequency beauty device, an optical beauty device, a micro-current beauty device, and the like.

[0058] Specifically, an installation space 101 is provided inside the beauty shell 10, and a light outlet 11 connected to the installation space 101 is provided on the beauty shell 10. The temperature-controlled light-transmitting member 20 is provided on the beauty shell 10 and arranged at the light outlet 11. The temperature-controlled light-transmitting member 20 has a contact surface 201 for contacting the skin, and the contact surface 201 contacts the user's skin to perform a cold compress treatment on the part to be treated. The light-emitting element 30 is provided in the installation space 101 and is provided corresponding to the light outlet 11. The light emitted by the light-emitting element 30 can pass through the temperature-controlled light-transmitting member 20 and be emitted from the light outlet 11 to the part to be treated. The electric heating element 40 is provided on the temperature-controlled light-transmitting member 20. The electric heating element 40 can generate heat when powered on, and the heat can be conducted to the part to be treated through the temperature-controlled light-transmitting member 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 beauty care of the user's skin, such as achieving effects such as hair removal, whitening, and freckle removal. During the beauty care process, the contact surface 201 of the temperature-controlled light-transmitting element 20 contacts the user's skin to perform a cold compress treatment on the beauty area, which can be used to calm the skin of the beauty area, inhibit skin swelling, and relieve the user's pain. In addition, the electric heating element 40 arranged on the temperature-controlled light-transmitting element 20 can generate heat when powered on, and can conduct the heat to the skin of the beauty area through the temperature-controlled light-transmitting element 20. For example, before hair removal, the skin can be heated by the electric heating element 40 to promote local skin blood circulation and open the pores, so that the skin and hair follicles of the beauty area can effectively absorb the light energy of the light emitted by the light-emitting element 30, thereby ensuring a high-quality beauty effect.

[0060] Furthermore, the beauty housing 10 is in a teardrop shape as a whole, which is convenient for holding and convenient for users to hold and perform beauty care operations. In other examples, the shape of the beauty housing 10 can also be set to a handle shape, a round cake shape, a cylinder shape, etc.

[0061] The beauty housing 10 has an installation space 101 therein, and a light outlet 11 is provided on the beauty housing 10 and communicates with the installation space 101. The light outlet 11 may be provided at the end of the beauty housing 10 or at the side of the beauty housing 10, and the location of the light outlet 11 may be determined according to the shape of the beauty housing 10 and the overall usage of the skin treatment device 100.

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

[0063] In some embodiments of the present application, the light emitting element 30 may 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 into visible light by the fluorescent powder to irradiate the skin, and is used to improve skin problems, such as removing yellowness, fading spots, brightening skin tone, improving redness of the skin such as red blood streaks, sensitive skin, rosacea, acne marks, and improving fine lines and fine pores on the skin.

[0064] In some examples, the light emitting element 30 may also be an LED lamp capable of providing high-energy light. If the light emitting element 30 is an LED lamp, an energy storage capacitor and a driving circuit may be configured in the installation space 101 .

[0065] Specifically, the energy storage capacitor is connected to the LED lamp to provide the LED lamp with the energy required for high-power light emission. The energy storage capacitor can release electricity to the LED lamp, causing the LED lamp to generate a pulsed high-power flash, thereby generating high-energy light in an instant and irradiating the skin.

[0066] The driving circuit may include a PWM controller, an NMOS switch tube, a freewheeling diode, a choke inductor, a current feedback resistor, and a filtering and 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 grounded via a 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 on or off of the NMOS switch tube, thereby controlling the on or off of the LED light circuit to achieve control of the beauty light.

[0068] The PWM controller can control the frequency, brightness, pulse duration and other parameters of the LED lamp by outputting control signals of different frequencies and duty cycles, thereby achieving adjustable light energy during beauty care and hair removal. The freewheeling diode and the choke inductor form a freewheeling circuit, which provides a delayed 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 capacitors are connected in parallel with the LED lamp. A protection circuit can also be included between the PWM controller and the NMOS switch tube, and the protection circuit can include a resistor and a diode, and the resistor and the diode are connected in parallel.

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

[0070] Furthermore, in some examples, the light emitting element 30 may be a halogen lamp, a tungsten filament lamp, a carbon filament lamp, a thermal radiation lamp, etc., in addition to the xenon lamp tube and the LED lamp shown above.

[0071] Furthermore, in some embodiments of the present application, a reflective cup 51 may be provided in the installation space 101 of the beauty housing 10. The reflective cup 51 has a reflective surface, which may be a coating formed by 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. 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, thereby improving the light output rate of the light emitting element 30, avoiding the waste of light energy, and ensuring that the skin treatment device 100 can efficiently perform beauty operations such as hair removal and skin care.

[0073] In some embodiments of the present application, a filter 52 may be further provided in the installation space 101 of the beauty housing 10. The filter 52 is provided 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 of the light emitted from the light outlet 11 is more in line with the wavelength required for hair removal, beauty care and other operations.

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

[0075] Accordingly, an air inlet and an air outlet may be provided on the beauty housing 10. By providing a fan 53, air can flow in the installation space 101 to accelerate the heat dissipation in the beauty housing 10, thereby avoiding the situation where the skin treatment device 100 cannot be used normally due to excessive heat.

[0076] Furthermore, in some embodiments of the present application, the skin treatment device 100 further includes a temperature-controlled light-transmitting member 20, which is disposed on the beauty housing 10 and arranged at the light outlet 11. The temperature-controlled light-transmitting member 20 has a contact surface 201 for contacting the skin, and the contact surface 201 contacts the user's skin to perform a cold compress treatment on the beauty area.

[0077] The temperature-controlled light-transmitting member 20 may be sapphire. Sapphire not only has good light transmittance, but also has good thermal conductivity. When sapphire is used to contact the skin, it can reduce the temperature of the skin, cool the user's skin, and bring a cool and comfortable feeling.

[0078] In other examples, the temperature-controlled light-transmitting element 20 may also be made of a light-transmitting material with good thermal conductivity, such as patolite, crystal, or glass.

[0079] The temperature-controlled light-transmitting member 20 is a rectangular parallelepiped structure, and the light outlet 11 corresponds to a rectangular outer contour of the temperature-controlled light-transmitting member 20. In other examples, the temperature-controlled light-transmitting member 20 can also be a cylindrical structure, and the light outlet 11 is circular; the temperature-controlled light-transmitting member 20 is a triangular cylindrical structure, and the light outlet 11 is triangular, etc.

[0080] The end surface of the temperature-controlled light-transmitting member 20 corresponding to the light outlet 11 is a contact surface 201, which is used to contact the skin to perform a cold compress treatment on the beauty area. The contact surface 201 can be set as a plane or an arc surface to improve the user's comfort when using the skin treatment device 100.

[0081] Combination Figure 4 As shown, in some embodiments of the present application, the skin treatment device 100 further includes a cooling element 54 , a main control module 61 and a capacitor energy storage module 62 .

[0082] The capacitor energy storage module 62 can be arranged in the beauty housing 10 and arranged near the side of the fan 53 away from the light outlet 11. The capacitor energy storage module 62 is used to store and output electrical energy. The main control module 61 is arranged inside the beauty housing 10. The main control module 61 is electrically connected to the light emitting element 30 and the capacitor energy storage module 62. The capacitor energy storage module 62 can supply power to the light emitting element 30 through the main control module 61. The capacitor energy storage module 62 is the energy storage capacitor mentioned in the above example when the light emitting element 30 is an LED lamp.

[0083] The main control module 61 is electrically connected to the capacitor energy storage module 62 to control the capacitor 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 is emitted from the light outlet 11 .

[0084] In some examples, the cooling element 54 is a semiconductor, which can be arranged in the installation space 101 of the beauty housing 10 and near the light outlet 11. The cooling element 54 is electrically connected to the main control module 61, so that the capacitor energy storage module 62 supplies power to the cooling element 54 through the main control module 61.

[0085] The cooling element 54 includes a cooling surface capable of generating cold and a heating surface capable of generating heat, and the cooling surface of the cooling element 54 is connected to the temperature-controlled light-transmitting element 20. When the cooling element 54 is powered on, the cold generated by the cooling surface is transferred to the temperature-controlled light-transmitting element 20, so as to perform a cold compress treatment on the beauty area through the contact surface 201.

[0086] In this example, the skin treatment device 100 may further include a conductive member 55 . The conductive member 55 may be made of copper, aluminum or other materials, and may include a conductive plate 551 and a ring-shaped conductive tube 552 .

[0087] The conduction plate 551 is arranged in contact with the heating surface of the refrigeration element 54, and the conduction tube 552 is arranged on the side of the conduction plate 551 away from the refrigeration element 54. The conduction plate 551 can transfer the heat of the refrigeration element 54 to the conduction tube 552, and then the conduction tube 552 diffuses the heat, thereby preventing the heat from accumulating on the refrigeration element 54 and affecting the cooling effect of the refrigeration element 54.

[0088] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the skin treatment device 100 further includes an electric heating element 40. The electric heating element 40 is disposed on the temperature-controlled light-transmitting element 20, and the electric heating element 40 can generate heat when powered, and the heat can be conducted to the beauty area through the temperature-controlled light-transmitting element 20.

[0089] In the present application, the electric heating element 40 may be an electric heating wire or an electric heating layer. In some examples, the electric heating wire or the electric heating layer may be arranged outside the temperature-controlled light-transmitting element 20, and the electric heating wire or the electric heating layer may generate heat when energized and transfer it to the temperature-controlled light-transmitting element 20, so that the temperature of the temperature-controlled light-transmitting element 20 increases.

[0090] In some examples, the electric heating wire or electric heating layer can be arranged inside the temperature-controlled light-transmitting member 20 and close to the outer surface of the temperature-controlled light-transmitting member 20. When the electric heating wire or electric heating layer is energized, it can generate heat and gradually increase the temperature of the temperature-controlled light-transmitting member 20 from the inside to the outside. The electric heating wire or electric heating layer is arranged close to the outer surface of the temperature-controlled light-transmitting member 20 to avoid a significant impact on the light transmittance of the temperature-controlled light-transmitting member 20, so that the light can be concentrated through the middle area of ​​the temperature-controlled light-transmitting member 20, ensuring the light output rate of the light emitted from the light outlet 11. In addition, when the electric heating layer is selected for the electric heating member 40, the electric heating layer can be made of a light-transmitting material to ensure its light transmittance.

[0091] In other examples, the heating wire or the heating layer can be arranged on the outer area of ​​the temperature-controlled light-transmitting member 20 away from the contact surface 201. This arrangement can ensure that the heating wire or the heating layer effectively conducts heat to the temperature-controlled light-transmitting member 20, and can also avoid the influence of the heating wire or the heating layer on the cold compress function of the temperature-controlled light-transmitting member 20.

[0092] The electric heating element 40 disposed on the temperature-controlled light-transmitting element 20 can generate heat when powered on, and can transfer the heat to the skin of the beauty area through the temperature-controlled light-transmitting element 20. For example, before hair removal, the electric heating element 40 can be used to apply heat to the skin to promote local skin blood circulation and open the pores, so that the skin and hair follicles of the beauty area to be treated can effectively absorb the light energy emitted by the light-emitting element 30, thereby ensuring a high-quality beauty effect.

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

[0094] The electric heating element 40 is electrically connected to the main control module 61, so that the capacitor 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 on, and transfer the heat 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 acts as a heat conduction component, so that the skin treatment device 100 has a hot compress function.

[0095] Further, see 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, and the functional module can be detachably mounted on the beauty housing 10 to achieve 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 when the user is not sensitive to the pain of hair removal but is more concerned about the effectiveness or time required for hair removal, the functional module can be removed from the beauty housing 10, and hair removal, beauty and skin care operations can be achieved only through the light-emitting element 30.

[0097] In this way, the loss of light emitted by the light emitting element 30 is reduced, and the shrinkage effect of the ice compress on the hair follicle pores that affects the pyrolysis effect of the light on the hair follicle area can be avoided, thereby ensuring a high-quality cosmetic effect.

[0098] In this embodiment, the skin treatment device 100 also includes a cover body 70, which is provided with a mounting opening 701, and the temperature-controlled light-transmitting component 20 is passed through and fixed in the mounting opening 701. The contact surface 201 of the temperature-controlled light-transmitting component 20 is flush with the surface of the cover body 70 or protrudes from the surface of the cover body 70.

[0099] The cover 70 is detachably connected to the beauty housing 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, so that the temperature-controlled light-transmitting element 20, the cover 70 and the electric heating element 40 as a whole constitute a functional module that can be removed from the beauty housing 10.

[0100] In some examples, the skin treatment device 100 further includes a first magnetic member 56 and a second magnetic member 57 capable of magnetic attraction, wherein the first magnetic member 56 is disposed on the cover 70, and the second magnetic member 57 is disposed on the beauty housing 10 and close to the light outlet 11. The first magnetic member 56 and the second magnetic member 57 are magnetically attracted to each other, so that the cover 70 is detachably connected to the beauty housing 10.

[0101] In other examples, the cover body 70 and the beauty housing 10 can also be detachably connected by means of bayonet connection, threaded connection, fastener locking, etc.

[0102] In this embodiment, the cover 70 is detachably connected to the beauty housing 10, and each beauty housing 10 can be equipped with multiple covers 70, and the cross-sectional area of ​​the temperature-controlled light-transmitting member 20 on each cover 70 can be set differently. By replacing different covers 70, the size of the light-emitting area can be adjusted.

[0103] In addition, in some embodiments, the cover 70 and the beauty housing 10 may be an integral structure, that is, the cover 70 and the beauty housing 10 are non-detachable structures. For the skin treatment device 100 in which the cover 70 and the beauty housing 10 are non-detachable, the cover 70 may be directly removed, and the temperature-controlled light-transmitting member 20 may be directly disposed on the beauty housing 10.

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

[0105] The skin treatment device 100 of this embodiment further includes an electrical connection terminal 58, which is disposed on the inner wall of the beauty housing 10 corresponding to the light outlet 11, and is electrically connected to the main control module 61. When the cover 70 is detachably connected to the beauty housing 10, the electrical connection terminal 58 can be electrically connected to the electric heating element 40 via the electrical interface 41, so that the electric heating element 40 is electrically connected to the main control module 61.

[0106] Furthermore, in some embodiments of the present application, the skin treatment device 100 further includes 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 may include a light emitter and a receiver. The light emitter can emit detection light toward the user's skin, and the detection light can be reflected by the user's skin to the receiver. 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 processes the parameter signal of the detection light emitted by the light emitter and the light signal transmitted by the receiver to obtain the user's skin color signal.

[0108] The main control module 61 can control the capacitor energy storage module 62 to output the electrical energy to the light-emitting element 30, the electric heating element 40 and / or the cooling element 54 according to the skin color signal, so that the beauty light emitted by the light-emitting element 30, the heat output by the electric heating element 40 and the cold output by the cooling element 54 meet the beauty requirements of different users with different skin colors, ensuring that each user can obtain a beauty care effect adapted to his or her personal skin color, greatly improving the user experience.

[0109] In this example, the skin temperature sensor 732 is used to contact the user's skin to measure the user's skin temperature. The skin temperature sensor 732 can transmit the measured skin temperature signal of the user to the main control module 61, and the main control module 61 can control the capacitor energy storage module 62 to output the amount of electric energy to the electric heating element 40 and / or the cooling element 54 according to the skin temperature signal, so that the user's skin temperature is a constant set value.

[0110] Specifically, when the skin treatment device 100 performs a hot compress, the main control module 61 can control the capacitor energy storage module 62 to output a set amount of electric energy to the electric heating element 40 according to the skin temperature signal, so that the hot compress temperature is controlled at 40°C to avoid overheating and causing damage to the user's skin. When the skin treatment device 100 performs a cold compress, the main control module 61 can control the capacitor energy storage module 62 to output a set amount of electric energy to the cooling element 54 according to the skin temperature signal, so that the cold compress temperature is controlled at 20°C to avoid overcooling and causing discomfort to the user during use.

[0111] Furthermore, if Figure 7 As shown, in some embodiments of the present application, the skin detection sensor 731 and the skin temperature sensor 732 are both arranged on the beauty housing 10, and are both arranged on the end surface of the beauty housing 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 to the main control module 61 through the wires or electrical connection components inside the beauty housing 10.

[0112] In this example, a first opening 71 and a second opening 72 are formed through the cover 70 . The first opening 71 and the second opening 72 are arranged on two sides of the temperature-controlled light-transmitting member 20 , respectively.

[0113] When the cover body 70 is detachably connected to the beauty shell 10, the skin detection sensor 731 is inserted into the first opening 71, and the skin temperature sensor 732 is inserted into 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 user's skin, so that the skin detection sensor 731 can detect the user's skin color, and the skin temperature sensor 732 can measure the user's skin temperature.

[0114] See also Figure 8 In some embodiments of the present application, the skin detection sensor 731 and the skin temperature sensor 732 can both be arranged on the cover body 70, that is, in this example, the temperature-controlled translucent element 20, the cover body 70, the electric heating element 40, and the skin detection sensor 731 and the skin temperature sensor 732 as a whole constitute a functional module that can be removed from the beauty shell 10.

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

[0116] Specifically, in some examples, the first electrical connection contact 741 is convexly provided on the end surface of the beauty housing 10 provided with the light outlet 11 and the first electrical connection contact 741 is electrically connected to the main control module 61, and the first electrical connection socket is provided on the skin detection sensor 731. The second electrical connection contact 742 is convexly provided on the end surface of the beauty housing 10 provided with the light outlet 11 and the second electrical connection contact 742 is electrically connected to the main control module 61, and the second electrical connection socket is provided on the skin temperature sensor 732.

[0117] When the cover body 70 is detachably connected to the beauty shell 10, the first electrical connection contact 741 can dock with the first electrical connection socket and establish an electrical connection, and the second electrical connection contact 742 can dock with the second electrical connection socket and establish an electrical connection, so that the skin detection sensor 731 and the skin temperature sensor 732 are electrically connected to the main control module 61.

[0118] In some other examples, the first electrical connection socket is provided on the end surface of the beauty housing 10 provided with the light outlet 11 and the first electrical connection socket is electrically connected to the main control module 61, and the first electrical connection contact 741 is provided on the skin detection sensor 731. The second electrical connection socket is provided on the end surface of the beauty housing 10 provided with the light outlet 11 and the second electrical connection socket is electrically connected to the main control module 61, and the second electrical connection contact 742 is provided on the skin temperature sensor 732.

[0119] When the cover body 70 is detachably connected to the beauty shell 10, the first electrical connection contact 741 can dock with the first electrical connection socket and establish an electrical connection, and the second electrical connection contact 742 can dock with the second electrical connection socket and establish an electrical connection, so that the skin detection sensor 731 and the skin temperature sensor 732 are electrically connected to the main control module 61.

[0120] In addition, if Figure 7 As shown, in some embodiments of the present application, the skin treatment device 100 may further include an ambient temperature sensor 733, which is used to measure the ambient temperature value. The ambient temperature sensor 733 is disposed on the outer surface of the beauty housing 10 and is electrically connected to the main 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 to turn on the hot compress function or the cold compress function through 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, thereby realizing that the skin treatment device 100 can intelligently adjust different functional modes according to changes in ambient temperature.

[0123] Furthermore, combined with Figure 5 and Fig. 9 As shown, in some embodiments of the present application, the cover 70 is detachably connected to the beauty housing 10, that is, the cover 70 together with the temperature-controlled light-transmitting element 20 and the electric heating element 40 can be removed from the beauty housing 10. In this embodiment, the skin treatment device 100 further includes a replacement cover 80 detachably connected to the beauty housing 10.

[0124] Specifically, the replacement cover 80 includes a main body 81 and a heating wire 82 disposed inside the main body 81. The main body 81 is a silicone member, and the heating wire 82 can generate heat when powered. The main body 81 made of silicone has a certain elasticity, and its contact surface 201 when contacting the user's skin can be increased or decreased accordingly 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 81 in each replacement cover 80 can be different.

[0125] A connecting port is provided at a position of the main body 81 corresponding to the heating wire 82. The skin treatment device 100 further includes an electrical connection terminal 58, which is provided on the inner wall of the beauty housing 10 corresponding to the light outlet 11, and is electrically connected to the main control module 61. When the replacement cover 80 is detachably connected to the beauty housing 10, the electrical connection terminal 58 can be electrically connected to the heating wire 82 through the connecting port, so that the heating wire 82 is electrically connected to the main control module 61.

[0126] By providing a replacement head, the electric heating element 40 on the temperature-controlled light-transmitting element 20 can be eliminated. When the hot compress function is needed, the cover 70 can be removed from the beauty housing 10, and the replacement head can be installed on the beauty housing 10 to apply hot compress to the user's skin. After the hot compress is completed, the replacement head can be removed, and the cover 70 can be selectively installed to perform hair removal or beauty skin care operations.

[0127] Furthermore, if Fig.10As shown, in some embodiments of the present application, the skin treatment device 100 may further include a host housing 91 and a line 92 connected between the host housing 91 and the beauty housing 10. The structure and related functional components of the beauty housing 10 have been described above and will not be repeated here.

[0128] In this embodiment, the capacitor energy storage module 62 is disposed inside the host housing 91. The light outlet 11 is provided on the side of the beauty housing 10, and the main control module 61 and the light emitting element 30 are both disposed inside the beauty housing 10. One end of the line 92 is connected to the beauty housing 10 and electrically connected to the main control module 61, and the other end of the line 92 is connected to the host housing 91 and electrically connected to the capacitor energy storage module 62.

[0129] The main body shell 91 and the beauty shell 10 are independently arranged, which not only realizes the reasonable arrangement of various functional components such as the main control module 61 and the capacitor energy storage module 62, making the beauty shell 10 easier to hold, but also when the user holds the beauty shell 10 and shines it towards the beauty area, the heat emitted by the capacitor energy storage module 62 arranged inside the main body shell 91 will not affect the holding of the beauty shell 10, reducing the phenomenon of the beauty shell 10 getting hot when the user holds it, 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 perform beauty care on the user's skin, such as achieving effects such as hair removal, whitening, and freckle removal. During the beauty care process, the contact surface of the temperature-controlled light-transmitting element contacts the user's skin to perform a cold compress treatment on the beauty area, which can be used to calm the skin of the beauty area, inhibit skin swelling, and relieve the user's pain. In addition, the electric heating element arranged on the temperature-controlled light-transmitting element can generate heat when powered on, and can conduct the heat to the skin of the beauty area through the temperature-controlled light-transmitting element. For example, before hair removal, the skin can be heated by the electric heating element to promote local skin blood circulation and open the pores, so that the skin and hair follicles of the beauty area can effectively absorb the light energy emitted by the light-emitting element, thereby ensuring a high-quality beauty effect.

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

[0132] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
