Description

A beauty device Technical Field

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

[0002] Current beauty devices on the market, such as handheld or desktop hair removal devices, skin rejuvenation devices, photon beauty devices, beauty masks, skin mirrors, and more, typically utilize an IPL light source and utilize independent filters to capture light waves of a predetermined wavelength for skincare applications, or they can double as makeup mirrors. The emitted light is filtered by the filters; however, the light intercepted by the filters is partially absorbed by internal components, causing photoaging and heat buildup in components. Alternatively, some light waves can be emitted from the edges of the filters, resulting in energy loss. To address this, component material properties and temperature resistance requirements have been increased, leading to increased costs and waste. Independent filters, however, complicate the structure and make assembly difficult. Technical issues

[0042] The following describes exemplary embodiments of the present application in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0043] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0044] Although the terms first, second, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the elements, components, regions, layers or sections discussed below can be referred to as second elements, components, regions, layers or sections without departing from the teachings of the example embodiments.

[0045] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," etc. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations.

[0047] Referring to Figures 1-27, the present application relates to a beauty device 1000, comprising a housing, a main control board mounted within the housing, a light source unit electrically connected to the main control board, and a power supply assembly. A light outlet is formed on the front face of the beauty device. The light outlet can be formed by a transparent panel 12 disposed within the front opening of the housing, or by an opening. A light source 20 comprises a light source and a reflector 21 mounted thereon. The light source and filter are integrally designed. Specifically, the light source comprises a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. A filter is integrally attached to the transparent lampshade. The filter can filter out light waves of a predetermined wavelength band, so that light generated by the light-emitting element is filtered by the filter on the light source lampshade to obtain output light of a predetermined wavelength band, which is then emitted from the light outlet and applied to the skin surface. The light emitted by the light source is a light wave of a predetermined wavelength band after filtering. For example, the light generated by the light emitting element is filtered by the filter film to obtain light in the wavelength bands of 500-1800nm ​​and 900-1800nm, which acts on the skin for beauty or treatment.

[0048] A filter film can be formed on the surface of a transparent lampshade through a coating process. Because the lampshade surrounds the light source, all light emitted by the light-emitting element is first filtered to obtain light waves of the desired wavelength band before being emitted by the light source. Filters can be prepared using an optical coating process, which involves optical coating on a transparent substrate. This technology is currently available. This application uses a transparent lampshade as the carrier transparent substrate for the coating process. Using the same coating process used to prepare the filter, the surface of the transparent lampshade is coated with a film, forming an integrated structure of the filter film and light source, resulting in a light source with built-in filtering capabilities.

[0049] Examples of coating processes include evaporation, ion beam sputtering (IBS), plasma sputtering, and atomic layer deposition (ALD), as described below. In evaporation, a source material in a vacuum chamber is heated or bombarded with an electron beam, causing it to evaporate. The vapor condenses onto the surface of the transparent lampshade, forming a uniform filter film. Evaporation is relatively gentle and can result in a loose or porous coating. In ion beam sputtering (IBS), a high-energy electric field accelerates an ion beam. This acceleration imparts significant kinetic energy to the ions. Upon impact with the source material, the ion beam "sputters" atoms from the target material. These sputtered target ions (atoms transformed into ions by the ionization zone) also possess kinetic energy and form a dense film upon contact with the transparent lampshade surface. Plasma sputtering is a general term for a range of technologies, such as plasma sputtering and magnetron sputtering. Ions in a plasma are accelerated into the source material, impacting loose energy source ions, which are then sputtered onto the transparent lampshade, forming a uniform filter film. In the atomic layer deposition process, the source material used for atomic layer deposition (ALD) exists directly in the form of gas. In a high-temperature vacuum chamber, the gaseous precursor is transmitted through non-overlapping pulses and deposited on the surface of the transparent lampshade to form a filter film.

[0050] In some embodiments, a coating layer is formed on a transparent lampshade according to the above-mentioned coating process; wherein, a single-band filter film that passes a single wavelength band is formed by single-band coating, for example, a single-band filter film that passes wavelengths of 500-1800nm, 900-1800nm, and 500-600nm; or, a single-band filter film that passes two or more wavelength bands simultaneously is obtained by multi-band coating, for example, a dual-band filter film that passes wavelengths of 500-600nm and 900-1800nm ​​is obtained by dual-band coating; or, a multi-zone filter film that passes wavelengths of different bands in different zones is obtained by zone coating on the transparent lampshade, for example, a filter film obtained by zone coating has a zone A of 500-600nm and a zone B of 900-1800nm. The zone-coated filter film can be switched between different zones by rotating the light source to obtain light of different wavelength bands. The rotating light source can be driven to rotate by installing a rotating structure such as a gear / rack / motor driven rotation at both ends of the light source.

[0051] In other embodiments, a filter film prepared by existing technology may be coated on the surface of the light source (i.e., the surface of a transparent cover of the light source such as a light bulb or a gun barrel) to form a light source with its own filtering function, and the filter film and the light source may be designed as one.

[0052] The internal light source of the beauty device of the present application can be an IPL light source, a tungsten filament light source, or a carbon fiber light source. Of course, other applicable light sources can also be used.

[0053] Tungsten filament or carbon fiber light sources use a tungsten or carbon fiber filament, or the luminescent material, installed in a bulb (tube). The filament emits light when electricity is applied. The bulb (tube) is kept in a vacuum or filled with a low-pressure inert gas or halogen gas to prevent the filament from oxidizing at high temperatures. When a halogen gas, such as iodine or bromine, is filled into the bulb (tube) of a tungsten filament or carbon fiber light source, a halogen lamp (also known as a tungsten-halogen lamp) is created. Tungsten filament or carbon fiber light sources are incandescent lamps, using the same structure as incandescent lamps.

[0054] Tungsten filament and / or carbon fiber are used as the luminescent material, i.e., the filament. A certain proportion of inert gas or halogen gas can be filled into the bulb (lamp tube) to increase the life of the light source. The spectral distribution of the tungsten filament and / or carbon fiber lamp can be changed by adjusting the gas pressure and gas ratio in the lamp, adjusting the current pulse or supply voltage, etc.

[0055] Tungsten filament or carbon fiber light sources offer full-spectrum and constant-on characteristics. They generate a full spectrum of light, including both visible and invisible light. After filtering through a filter, light in a predetermined wavelength band is obtained for skin beautification or treatment. For example, visible light of 500-600nm can reduce epidermal melanin, while near-infrared light from 900 to 2500nm can directly reach the dermis and basal layer, stimulating collagen regeneration and repairing the basal layer.

[0056] The following are specific application examples of beauty devices that use the above-mentioned light source with built-in filtering function of this application. It can be applied to various photon beauty devices such as skin beauty devices with light sources (such as hair removal devices, skin rejuvenation devices, introduction devices or other beauty devices with therapeutic functions), skin beauty mirrors, beauty masks, etc.

[0057] Referring to Figures 1-4, a beauty device 1000 according to a first embodiment of the present application is a handheld light-based skin beautification device. The device comprises a housing with a cavity formed therein. A light outlet for the skin beautification device is provided at the front end of the housing. In this embodiment, the light outlet is relatively small, for example, 1-4 square centimeters, and is used for hair removal or skin beautification or treatment. The front end of the housing 10 is connected to a front housing 11, and the rear end is connected to a rear housing 15. A transparent panel 12, comprising a transparent crystal (identical reference numeral 12), is mounted within the opening at the front end of the housing 10, covering the opening and forming the light outlet for the skin beautification device. The rear end of the housing is capped by the rear housing 15. The housing houses components such as a light source, a power supply assembly, a main control board 40, a fan 60, a semiconductor cooling element 80, and a heat dissipation assembly 70. The transparent crystal 12 is independently provided and cooled by the semiconductor cooling element 80, or alternatively, the transparent crystal 12 is the cold surface of a semiconductor cooling element (see Figure 5).

[0058] The light source unit includes a light source 20 and a reflector 21. Light source 20 can be an IPL light source, a tungsten filament light source, or a carbon fiber light source. For example, a halogen lamp is used. Light source 20 includes a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. A filter is integrally attached to the transparent lampshade. The filter filters light within a predetermined wavelength range. Light generated by the filament is filtered by the filter on the lampshade to produce light within the predetermined wavelength range. This light is then emitted from the light outlet and applied to the skin surface for cosmetic or therapeutic treatment. In this embodiment, light source 20 has a built-in filtering function, with the light source and filter being an integrated design.

[0059] The cavity inside the housing 10 is provided with a lamp holder bracket 13 , and a light source 20 with a self-filtering function and a reflector 21 are installed in the lamp holder bracket 13 . The light source 20 with a self-filtering function is installed in the reflector 21 .

[0060] With reference to the light source portion shown in Figure 6 , the reflector 21 forms a cavity within itself for mounting the light source 20 and forming a light exit passage 212. The reflector 21 includes a curved (but not limited to curved) rear housing 210 and a front housing 211 forming the light exit passage 212. The front housing 211 is integrally connected to the front housing 210 or forms a one-piece structure. The light exit passage 212 is formed within the front housing 211, with an open front end that connects to the light exit port on the front face of the skin beauty device or abuts against the transparent crystal (translucent panel) 12. The rear housing of the reflector 21 conforms to the shape of the light source 20, enclosing the light source 20, which is mounted within the rear housing. The reflector's inner wall is reflective, causing light emitted from the light source 20 to be reflected forward from the inner wall of the rear housing 210 and reflected from the inner wall of the front housing 211, allowing the entire light wave to be projected from the light exit passage 212 to the light exit port. The arrow lines in Figure 6 indicate the reflection and emission directions of the light waves. The light source portion of this embodiment adopts an integrated design of the light source and the filter film to obtain a light source 20 with a built-in filtering function. There is no need to set up an independent filter between the light outlet and the light source, saving the filter material and the cost of assembly and maintenance. The light source 20 has a built-in filtering function, and the ultraviolet light and the light / heat damage to the surrounding components caused by intercepted photons have been eliminated in the output light. The light emitted by the light source is directly projected to the light outlet through the reflector 21, shortening the distance between the light source and the light outlet and improving the output of light energy. After removing the independent filter, the light source reflector 21 can be designed with the light source 20 to form a complete light outlet channel 212, without any side leakage of photons, effectively improving the output of light energy.

[0061] A heat shield 14 is also installed inside the housing 10. The heat shield 14 is adapted to the inner wall of the housing to form a relatively closed space with the inner wall of the housing to install the main control board 40 to protect the main control board 40. The lamp holder 13 and the heat shield 14 can be the same bracket or two independently arranged brackets. A number of ventilation holes 101 can be provided at any appropriate position on the housing (housing 10 and / or front housing 11 and / or rear housing 15) as the air inlet and outlet of the skin beauty instrument, which are connected to the air flow in the air duct inside the housing to form a heat dissipation duct. A button hole is provided on the housing to install the button group 42. A through hole is provided on the rear housing 15 to install the power interface 41.

[0062] The main control board 40 is electrically connected to the keypad 42, the light source 20, and the power supply assembly. A power supply interface 41 is connected to the main control board. The main control board 40 is equipped with corresponding circuits and functional modules based on functional requirements. These circuits and functional modules can utilize existing technologies or commercially available electronic components. For example, the main control board 40 is equipped with a power module, multiple control modules, an RF / EMS driver module, a temperature control module, and the like.

[0063] The power supply assembly includes a battery 30 and / or a power interface 41. The battery 30 can be a rechargeable battery that is charged through the power interface 41, or a disposable battery that is replaceable. Alternatively, the battery 30 may not be provided and the power supply can be directly connected to an external power source through the power interface 41.

[0064] The button group 42 is configured as needed but is not limited to a power button, a light source control button, a setting button, a radio frequency / EMS switch, etc.

[0065] In this embodiment, the light-transmitting panel mounted on the front of the skin-beautifying device is a transparent crystal 12, forming a light outlet. A semiconductor cooling element 80 cools the transparent crystal 12. The shapes of the transparent crystal 12 and the semiconductor cooling element 80 are compatible, and the semiconductor cooling element 80 cools the periphery of the transparent crystal 12, specifically the area around the light outlet. The transparent crystal 12 is entirely transparent and can come into contact with the skin.

[0066] Semiconductor cooler 80, also known as a thermoelectric cooler (TEC), heat pump, or Peltier cooler, comprises a central semiconductor particle layer 82 and two ends, hot and cold surfaces 83 and 81. It also includes a pair of positive and negative electrodes that electrically connect the semiconductor cooler's circuit to a control module located on the main control board 40 or a separate control board, which is electrically connected to the main control board 40. The two ends of the galvanic particle layer are the cold end and the hot end. A cold end circuit is provided on the cold surface 81, and a hot end circuit is provided on the hot surface 83. The cold end circuit is electrically connected to the cold end of the semiconductor particle layer, and the hot end circuit is electrically connected to the hot end of the semiconductor particle layer, forming the internal circuit of the semiconductor cooler. When power is applied, a temperature difference is created between the cold and hot surfaces 81 and 83.

[0067] In some embodiments, when the transparent crystal 12 serves as the cold surface 81 of the semiconductor refrigeration component, one or more cold end circuits are provided on the transparent crystal, and the one or more cold end circuits are welded and electrically connected to the cold ends of one or more semiconductor particle layers 82. The hot end of each semiconductor particle layer 82 is a hot surface 83, and a hot end circuit is provided on the hot surface 83, which is welded and electrically connected to the hot end of the semiconductor particle layer 82. After the cold end circuit is electrically connected to the cold end of the galvanic particle layer and the hot end circuit is electrically connected to the hot end of the galvanic particle layer, an internal circuit of the semiconductor refrigeration component 80 is formed. After power is turned on, a temperature difference is formed between the cold surface 12 / 81 and the hot surface 83 of the transparent crystal. The cold surface 12 / 81 of the transparent crystal is at a low temperature for cooling, and the hot surface 83 is at a high temperature and needs to be dissipated.

[0068] For example, the semiconductor cooling element 80 is annular in shape, with a hot surface 83 and a cold surface 81 forming matching rings, and a semiconductor particle layer 82 arranged in a matching ring shape. A through hole in the center of the ring allows light waves emitted by the light source 20 to pass through. The hot surface 83 / cold surface 82 is a substrate made of a thermally conductive material or other type of heat transfer structure. For example, they can be made of a single thermally conductive material such as aluminum, copper, or graphene. They can also be heat pipes, vapor chambers (VCs), superheat pipes, or superheat plates such as ALVCs (aluminum superconducting tubes or plates) that utilize phase change (evaporation and condensation) to rapidly transfer heat or cold. The annular semiconductor cooling element 80 is positioned on the rear surface (back side) of the transparent crystal 12. The annular cold surface 82 aligns with the edge of the transparent crystal 12 to cool all four sides of the transparent crystal 12, cooling the entire surface of the transparent crystal 12. The transparent crystal 12 is clamped to the front housing 11, and the semiconductor cooling element 80 is also mounted within the front housing 11.

[0069] In another alternative embodiment, referring to Figure 5 , the cold surface 81 of the semiconductor cooling element 80 is a whole transparent crystal. In this case, the transparent crystal cold surface 81 and the transparent crystal 12 are used together, eliminating the need for a separate transparent crystal 12. The transparent crystal cold surface 12 / 81 covers the light outlet, and the semiconductor cooling element 80 is clamped and mounted by the front housing 11. The transparent crystal cold surface can come into contact with the skin. The semiconductor particle layer 82 and the hot surface 83 can be annular and welded to the edge of the transparent crystal cold surface 81.

[0070] A heat sink assembly 70 is also installed within the housing 10 to dissipate heat from the semiconductor cooler 80. This assembly 70 includes a heat sink 71 and a heat conductor 72. One end of the heat conductor 72 is connected to the heat sink 71 for rapid heat transfer, while the other end is connected to the hot surface 83 of the semiconductor cooler 80 for rapid heat transfer, rapidly transferring heat from the hot surface to the heat sink 71 for dissipation. The shapes of the ends of the heat conductor are designed based on the principle of rapid heat transfer. For example, the front end is annular, maximizing contact area with the annular hot surface 83 for heat transfer. The rear end is a straight rod inserted into a set of parallel heat sinks 71 for contact and heat transfer. In other embodiments, the front end may be curved, resulting in an overall L-shape for the heat conductor; other shapes are also possible. The heat conductor 72 is a heat transfer structure that can be made of a single thermally conductive material such as aluminum, copper, or graphene, or a component that utilizes phase change (evaporation and condensation) such as a heat pipe, a heat spreader (VC), a superheat pipe, or a superheat plate such as an ALVC (aluminum superconducting tube or plate). The heat sink 71 is preferably located behind the ventilation holes on the housing to facilitate air cooling and heat dissipation.

[0071] The fan 60 can be mounted on one side of the heat sink 71. The fan 60 includes a housing and internal rotating blades. The fan housing is provided with a plurality of ventilation holes, which can be provided on the upper and lower sides of the fan (axial direction) or on the side vertical housing to serve as the fan's air inlet / outlet.

[0072] The cosmetic device 1000 of this embodiment is also equipped with a radio frequency component or an EMS component, including several pairs of radio frequency / EMS electrodes 90. For example, the radio frequency / EMS electrodes are a set of cylindrical electrodes with corresponding through-holes provided around the periphery of the transparent crystal 12 and / or on the semiconductor refrigeration element 80. One end of the radio frequency / EMS electrode 90 is mounted within the through-hole, with the front end exposed outside the transparent crystal 81 / 12 for contact with the skin, and the rear end is electrically connected to the main control board 40 or to a separately provided radio frequency / EMS control board. The main control board 40 or radio frequency / EMS control board is equipped with functional modules such as a control module, a power module, and a radio frequency / EMS driver module. When the radio frequency / EMS control board is provided separately, the radio frequency / EMS control board is electrically connected to the main control board 40, and the power module of the radio frequency / EMS control board is powered by a shunted power module on the main control board 40. In other embodiments, the radio frequency / EMS control board can also be integrated into the main control board 40. The RF / EMS electrode 90 can be in the shape of a bar, column, arc, ring or any other suitable shape. The RF / EMS electrode 90 and the light outlet can be arranged overlapping or arranged around the light outlet, and can be arranged in a pair or more. The rear end of each pair of RF / EMS electrodes forms the RF / EMS positive and negative poles, which are electrically connected to the RF / EMS control board or the main control board. The RF / EMS control board or the main control board 40 provides the voltage required for the corresponding gear to the RF / EMS drive module through the control power module. The RF / EMS drive module converts the DC power supply voltage into a high-voltage sine wave to the output control module through the step-up transformer. The output control module outputs the RF / EMS current to the user's skin through the RF / EMS electrode 90 to perform RF / EMS treatment or RF / EMS beauty on the skin. The RF / EMS electrodes and the RF / EMS mainboard / main control board or its integrated functional modules can be implemented using models of existing technologies.

[0073] In this embodiment, multiple pairs of RF / EMS electrodes 90 are mounted within through-holes provided in the transparent crystal 12 and the semiconductor cooler 80. Electrode points are formed on the outer surface of the transparent crystal 12, with their positive and negative terminals electrically connected to the main control board 40. The transparent crystal 12 and the semiconductor cooler 80 are mounted in a close-fitting manner and are both mounted within the front housing 11. The annular front end of the heat-conducting member 72 of the heat dissipation assembly 70 abuts the annular hot surface of the semiconductor cooler 80. The heat sink 71 is mounted behind the ventilation holes 101 of the housing 10. The ventilation holes 101 are a set of fine through-holes that are in airflow communication with the heat sink 71. The fan 60 can be positioned above and below the heat sink 71, with the airflow between the two being in airflow communication. The light source is mounted within the lamp holder bracket 13, located within the front end of the housing 10. The light source is the light source 20, which is mounted within the reflector 21. A heat dissipation duct can be formed within the reflector to dissipate heat from the light source, or a heat sink can be provided outside the reflector to dissipate heat from the reflector. The front end of the reflector 21 defines a light outlet channel 212. A battery 30 is installed inside the rear end of the housing. The device is powered on by the button assembly 42, activating the light source. Light emitted by the light source 20 is filtered by a filter membrane integrated with the light source to obtain a predetermined wavelength band. This light is then projected through the light outlet channel 212 to the light outlet, where it acts on the skin for photon beauty treatment. The RF / EMS function is activated by the button assembly 42, and the RF / EMS electrode 90 generates an RF / EMS current that acts on the skin for RF / EMS therapy. The RF / EMS function and the photon beauty function can be activated simultaneously or selectively. The heat dissipation assembly 70 dissipates heat from the semiconductor cooling element 80. The cold surface of the semiconductor cooling element 80 cools the transparent crystal 12, which is in contact with the skin; alternatively, the cold surface of the transparent crystal 12 is in contact with the skin. Fan 60 operates through the ventilation holes in the skin of the skin beauty device, drawing in cool air to cool the heat sink 71 and the light source.

[0074] Referring to Figure 7 , the beauty device 1000 of the second embodiment of the present application is also a handheld skin beautifying device. Unlike the first embodiment, it does not include a radiofrequency / EMS component, namely, it does not include the radiofrequency / EMS electrodes 90 or the radiofrequency / EMS control board (or the functional modules corresponding to the radiofrequency / EMS component are not provided on the main control board 40). The rest of the structure and functions are the same as those of the first embodiment, and the specific implementation directly refers to the above embodiment.

[0075] Based on a variation of the first and second embodiments described above, one or more semiconductor cooling elements 80 are positioned on the sides of the transparent crystal 12 to cool it. The shape of the one or more semiconductor cooling elements 80 matches the shape of the side of the transparent crystal 12, and the cold surface 82 of the semiconductor cooling element 80 fits closely against the side of the transparent crystal 12, rapidly cooling it. The transparent crystal 12 covers the light outlet at the front of the skin beauty device. The remaining structure is the same as the first and second embodiments described above, and the description of these embodiments will be directly referenced for implementation.

[0076] Referring to Figures 8-9, the beauty device 1000 of the third embodiment of the present application is also a handheld skin care device. Unlike the first embodiment, this embodiment utilizes dual light sources 20 and 20' in its light source portion. These dual light sources are arranged side by side and mounted within a reflector 21. They project light toward a light outlet through a light outlet channel 212 within the front end of the reflector 21. For example, the dual light sources may be one or more of an IPL light source, a tungsten filament light source, or a carbon fiber light source. Each light source 20 comprises a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. A filter is integrally attached to the transparent lampshade. The filter filters out light within a predetermined wavelength range, ensuring that light emitted by the light source is filtered by the filter on the lampshade to obtain light within the predetermined wavelength range. This light is then emitted from the light outlet and applied to the skin surface for cosmetic or therapeutic treatment. Each light source 20 in this embodiment has a built-in filter function, and the light source and filter are integrally designed. The remaining structure of the beauty device of this embodiment is the same as that of the first embodiment, and the description of the first embodiment can be directly incorporated into its implementation.

[0077] During use, the device is powered on via button assembly 42, activating light sources 20 and 20', which can be halogen lamps and / or IPL lamps. Light waves emitted by light sources 20 and 20' are filtered through their own filters to obtain wavelengths within a predetermined range. These light waves pass through the light outlet channel 212 within the reflector, through the light outlet port (transparent crystal 12), and onto the skin for photon beauty and treatment. Activating the RF / EMS function via button assembly 42 generates RF or EMS currents at the electrode points formed by the RF or EMS electrodes 90 on the front face of the skin beauty device, applying RF / EMS therapy to the skin. The RF / EMS function can be activated simultaneously with the photon beauty and treatment function, or alternatively. The heat dissipation assembly 70 dissipates heat to the semiconductor cooling element 80, whose cold surface cools the transparent crystal 12, which then contacts the skin to form an ice compress or pre-cooling effect. The ventilation holes 101 on the skin beauty instrument housing draw in cold air into the interior to cool the heat sink 71 and the light source. The fan 60 strengthens the air flow and promotes the heat dissipation speed.

[0078] In this embodiment, the annular semiconductor refrigeration element 80 is attached to the back of the transparent crystal 12 and cools the area around the light outlet. Alternatively, the transparent crystal 12 and the semiconductor refrigeration element 80 are an integral structure, the transparent crystal is the cold surface of the semiconductor refrigeration element, the intermediate galvanic particle layer 82 and the hot surface 83 of the semiconductor refrigeration element are annular, and the cold surface 12 / 81 of the transparent crystal is in direct contact with the skin for cooling. Alternatively, one or more semiconductor refrigeration elements 80 are arranged on the side of the transparent crystal 12 (different from the light outlet surface), the front of the transparent crystal (light-transmitting panel) 12 forms the light outlet, and one or more semiconductor refrigeration elements 80 cool the light outlet from the side of the transparent crystal 12. Alternatively, the transparent crystal 12 is a common cold surface for one or more semiconductor refrigeration elements, and the transparent crystal (light-transmitting panel) 12 directly serves as the cold surface of one or more semiconductor refrigeration elements, while forming the light outlet.

[0079] Referring to Figure 10 , the beauty device 1000 of the fourth embodiment of the present application is similar to the third embodiment and is a handheld skin care device that utilizes dual light sources. Each light source 20 includes a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. A filter is integrally attached to the transparent lampshade. The filter filters out light waves within a predetermined wavelength range, ensuring that the light emitted by the light source 20 is filtered by the inherent filter to obtain light waves within the predetermined wavelength range. This light source 20 is then emitted from the light outlet and acts on the skin surface for cosmetic or therapeutic treatment. Each light source 20 in this embodiment has its own built-in filter function, and the light source and filter are integrally designed. This embodiment differs from the third embodiment in that it lacks an RF / EMS component and therefore lacks RF / EMS functionality. The remaining structure of this embodiment is identical to that of the third embodiment or other aforementioned embodiments, and the description of these embodiments can be directly incorporated and omitted here.

[0080] The beauty device 1000 shown in Figures 8-10 utilizes dual light sources 20 and 20', one of which can be an IPL light source, and the other a tungsten filament light source or a carbon fiber light source. Tungsten filament or carbon fiber light sources provide infrared heating, with good spectral continuity, a wide spectrum (reaching 300-2500nm), and a rich near-infrared spectrum. The IPL light source in the dual light source is an intense pulsed light with a short emission time and high peak light energy. The photochemical reaction generated by the light energy on the target skin is rapid, instantly raising the target skin temperature. However, the spectral continuity is poor, and the near-infrared spectrum is limited. The advantages of combining these two light sources are:

[0081] 1) Spectral complementarity: the spectral band values ​​in the same interval increase, and the two complement each other's spectral values;

[0082] 2) Complementary advantages: Within the same wavelength range, the stable wavelength of the tungsten filament light source or carbon fiber light source is used to preheat the skin target to increase the base temperature of the skin target and reduce the loss of IPL light energy. The instantaneous light energy of the IPL intense pulsed light acts on the heated skin target. This method can reduce the energy of the IPL light source while achieving the same therapeutic effect, increase the luminous speed of the IPL light source, and reduce the impact of high-energy IPL lamps, thus achieving faster, gentler, safer, and more effective treatment goals.

[0083] 3) Enhanced beauty and other skin disease treatment range: Through the 900-2500nm band of the near-infrared spectrum of tungsten filament light source or carbon fiber light source, resonance is generated with the water molecules in the skin (major medical journals / papers / magazines / clinical reports have confirmed the interaction between this near-infrared band and water molecules), the underlying skin temperature is increased. At the same time, with the help of cooling and temperature control measures, the skin is cooled on the outside and heated on the inside. The instantaneous photochemical thermal energy impact of the IPL light source is then used to achieve a more comfortable body feeling and better treatment effect.

[0084] When using the dual-light source therapeutic device 1000, you can choose to start both light sources at the same time, or you can choose to use one of the light sources.

[0085] In the first to fourth embodiments described above, the light outlet on the front face of the beauty device 1000 is formed by a light-transmitting panel 12. The light-transmitting panel can be made of a transparent crystal material, transparent plastic or other existing transparent materials. When the semiconductor refrigeration element 80 is used as a light-transmitting panel, the cold surface 81 or the hot surface 83 of the semiconductor refrigeration element 80 can be made of the transparent crystal described in the above embodiments, or other light-transmitting materials.

[0086] 11-13 , the beauty device 1000 of the fifth embodiment of the present application is a skin beauty mirror, comprising a housing 10 and a main control board 40 installed in the housing 10, as well as a light source unit and a power supply assembly electrically connected to the main control board 40. The light source unit comprises a light source 20 and a reflector 21 on which the light source 20 is installed. A heat sink 22 is also provided on the back of the reflector. A temperature sensor assembly 50 electrically connected to the main control board 40 is also provided in the housing. The front end of the housing 10 is open and connected to a matching front housing 11, which is annular. The transparent light-transmitting panel adopts a transparent crystal 12 or a semiconductor refrigeration element 80 having a transparent crystal cold surface, which is fixedly mounted on the front end of the housing 10 by the front housing 11, so that the transparent crystal forms the light-emitting surface of the front end of the skin beauty mirror or serves as a mirror surface. The light-emitting surface has a relatively large area to form a large-area mirror surface.

[0087] The overall shape of the skin-beautifying mirror in this embodiment can be spherical, hemispherical, square, or other shapes, with a large light outlet or mirrored surface formed on the front surface. The front end of the housing 10 is adapted to fit the front shell 11. The housing 10 can be spherical, hemispherical (including hemispherical or partially spherical), square, or other shapes, with a cavity formed within. The light source, power supply assembly, and main control board are mounted within this cavity.

[0088] The light-transmitting panel 12 can be made of sapphire, quartz, K9, glass, or other suitable translucent materials. In this embodiment, transparent crystal 12 is used as the light-transmitting panel. The temperature of the light-transmitting panel is controlled by a temperature sensor assembly 50. The entire light-transmitting panel / transparent crystal covers the light outlet at the front of the housing, forming a large light-emitting surface or mirror. This light-emitting surface / mirror is approximately the same size as the entire front surface, enabling large-area full-body skin beautification, making it quicker and more efficient to use.

[0089] The light source unit includes a light source 20 and a reflector 21. Light source 20 can be an IPL light source, a tungsten filament light source, or a carbon fiber light source. For example, a halogen lamp is used. Light source 20 includes a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. A filter is integrally attached to the transparent lampshade. The filter filters out light waves of a predetermined wavelength range, so that light waves emitted by light source 20 are filtered by the filter on the lampshade to obtain light waves of the predetermined wavelength range. This light source 20 is then emitted from the light outlet and acts on the skin surface for cosmetic or therapeutic treatment. In this embodiment, light source 20 has a built-in filtering function, and the light source and filter are integrally designed. Reflector 21 has a large reflective surface and an internal cavity for mounting light source 20 and forming a light output channel. The reflector 21 comprises a curved (but not limited to curved) housing with an open front end. The front opening of the reflector 12 is covered by a translucent panel / transparent crystal 12. Light emitted by the light source 20 is filtered by a filter on the light source surface to obtain light waves within a predetermined wavelength band. After being reflected by the inner surface of the reflector, it is directly projected onto the translucent panel / transparent crystal 12. After passing through the translucent panel / transparent crystal 12, it illuminates the skin surface for skin beautification or treatment. The light source portion of this embodiment utilizes an integrated light source and filter design to provide a light source 20 with built-in filtering capabilities. This eliminates the need for a separate filter between the light outlet and the light source, saving on filter material, assembly, and maintenance costs. The built-in filtering capabilities of the light source 20 eliminate ultraviolet radiation and photothermal damage to surrounding components caused by intercepted photons. Light emitted by the light source is directly projected onto the light outlet through the reflector 21, shortening the distance between the light source and the light outlet, improving light output, and eliminating space for photons to leak out, effectively increasing light output.

[0090] The reflector 21 is made of a thermally conductive material. Its edges mate with the front edges of the front shell 11 and the front edge of the outer shell 10, securing it between the two. For example, the reflector is a (partial) spherical surface, with its edges secured by the front shell 11. The light source 20 is mounted at the inner top center. A housing is formed at the top center of the reflector 21. The housing has a through hole and protrudes from the inside of the reflector 21 toward the back. The light source 20 is inserted into the housing, and its electrodes extend rearward from the housing to connect with the main control board 40.

[0091] A heat sink 22 is provided on the back of the reflector 21. Its shape matches that of the reflector 21, the front housing 11, and the outer housing 10, and it fits snugly against the back of the reflector 21 for rapid heat transfer. Alternatively, the heat sink 22 and the reflector 21 may be integrally formed. The edges of the heat sink 22 are clamped to the front housing 11. The inner surface of the heat sink 22 matches the shape of the reflector's back, and in the examples shown, it is spherical, designed to maximize contact area and fit snugly. A through-hole is provided in the center of the heat sink 22, and a seat provided at the top center of the reflector 21 passes through the through-hole to secure the heat sink 22. The heat sink 22 is a heat transfer structure and can be made of a single thermally conductive material such as aluminum, copper, or graphene, or it can be a heat pipe, vapor chamber (VC), super heat pipe, or super heat plate, such as ALVC (aluminum superconducting tube or plate), that utilizes phase change (evaporation and condensation).

[0092] A heat shield 14 is also provided within the housing 10. The heat shield 14 is mounted outside the rear side of the reflector 21 and the heat sink 22. For example, a through hole is provided in the center of the heat shield 14. A seat cover provided at the top center of the reflector 21 passes through the through hole in the center of the heat sink 22 and the through hole in the center of the heat shield 14 and then abuts against the main control board. After the light source 20 is mounted on the seat cover, its electrodes pass through the through hole in the heat shield and are electrically connected to the main control board 40. The shape of the heat shield 14 matches the shape of the inner wall of the housing 10 and fits tightly against the inner wall of the rear housing. It can be made of an insulating material and separates the cavity within the rear housing from the front to the back, thereby isolating the light source portion from the main control board 40 and providing thermal insulation and sealing protection for the main control board 40. For example, the heat shield 14 is disc-shaped.

[0093] The main control board 40 is mounted within the cavity enclosed by the heat shield 14 and the housing 10. It is electrically connected to the keypad, the light source 20, the temperature sensor assembly 50, the battery 30, and the power interface 41. The main control board 40 is equipped with corresponding circuits and functional modules based on functional requirements. These circuits and functional modules can be configured using existing techniques or commercially available electronic components, along with corresponding functional software. For example, the main control board 40 includes a power module, multiple control units, a radio frequency module, a temperature control module, and the like.

[0094] Battery 30 can be a rechargeable battery, charged via power port 41. Alternatively, it can be a disposable, replaceable battery, or the battery can be omitted and powered directly from an external power source via power port 41. Battery 30 is also mounted within the cavity enclosed by thermal insulation plate 14 and housing 10.

[0095] The power interface 41 is provided on the housing 10 for connecting to an external power source. The housing 10 is provided with buttons, such as a power on / off button, a light source control button, a mode setting button, a radio frequency switch, etc., as needed.

[0096] In this embodiment, the temperature sensor assembly 50 is a temperature sensor PCBA, which can be a flexible PCBA, but is not limited thereto. It can also be other temperature sensors in the prior art. The front end of the temperature sensor assembly 50 contacts the light-transmitting panel / transparent crystal 12 to detect the temperature of the transparent crystal; the rear end is electrically connected to the main control board 40 to transmit the temperature information to the control unit on the main control board. When the light emitted by the light source 20 is filtered to obtain the desired wavelength band and passes through the light-transmitting panel / transparent crystal 12 to illuminate the skin, the temperature of the light-transmitting panel / transparent crystal is detected by the temperature sensor assembly 30, and the power and switching of the light source 20 are controlled by the main control board 40 to control the temperature range, thereby avoiding burns to the skin during prolonged use.

[0097] In the skin beautifying device 1000 of this embodiment, the light emitted by the light source 20 is filtered by the built-in filter to obtain light waves of the desired wavelength band. The light is then irradiated to the skin at a constant temperature through the light-transmitting panel / transparent crystal 12. The filter on the surface of the light source can filter out undesirable wavelengths, obtaining light waves of the predetermined wavelength band, which are then targeted to act on the skin to achieve the purpose of beautifying the skin. For example, the filter on the surface of the light source is in the 500-600nm wavelength band. The light emitted by the light source 20 is filtered by the built-in filter to obtain light waves of the desired wavelength band, which then pass through the light-transmitting panel / transparent crystal 12 and act on the epidermis of the human body; while the filter on the surface of the light source is in the 900-1800nm ​​wavelength band, the light waves emitted from the light-transmitting panel act on the basal layer and melanocytes of the human body.

[0098] Referring to Figures 14-16, the sixth embodiment of the cosmetic device 1000 of the present application is a skin-beautifying mirror. It differs from the fifth embodiment in that the light-transmitting panel 12 is replaced with a semiconductor cooling element 80 with transparent crystal end faces. A semiconductor cooling element, also known as a thermoelectric cooler (TEC), heat pump, or Peltier cooler, comprises a central semiconductor particle layer 82, a hot surface 81, and a cold surface 83 at each end. It also includes a pair of positive and negative electrodes that electrically connect the semiconductor cooling element's circuit to a control unit located on the main control board 40 or a separate control board, which is electrically connected to the main control board 40. The hot surface 83 and / or the cold surface 81 are configured as transparent crystals. For example, the cold surface 81 is a fully transparent crystal that can contact the skin, while the hot surface 83 and the semiconductor particle layer 12 are configured in a ring shape. The hot-end circuit (e.g., a conductor) is mounted on the annular edge of the transparent crystal cold surface 81 and is welded and electrically connected to the cold end of the semiconductor particle layer. The hot surface 83, a thermally conductive substrate, also features a hot-end circuit (e.g., a conductor) welded and electrically connected to the hot end of the semiconductor particle layer, thereby connecting the internal circuit of the semiconductor refrigeration unit and electrically connecting the positive and negative electrodes to the control unit. The transparent crystal cold surface, corresponding to the middle area between the annular hot surface and the semiconductor particle layer, forms the light-emitting surface, which can be configured as a large, light-transmitting panel / mirror that approximates the entire front end of the skin beauty device.

[0099] The hot surface 83 of the semiconductor cooler 80 is connected to a heat sink 16 for dissipating heat from the hot surface 83. The heat sink 16 is a heat transfer structure and can be made of a single thermally conductive material such as aluminum, copper, or graphene. Alternatively, it can be a component that utilizes phase change (evaporation and condensation), such as a heat pipe, a heat spreader (VC), a superheat pipe, or a superheat plate such as an ALVC (aluminum superconducting tube or plate). In this embodiment, the heat sink 16 is annular, with its annular end surface rapidly transferring heat to the annular hot surface 83 of the semiconductor cooler. The heat sink 16 can be positioned in close contact with the annular heat sink 16. The annular heat sink 16 fits snugly around the front outer wall of the reflector, providing thermal contact. The semiconductor cooler 80 is shaped to fit within the reflector's opening and seals the reflector 21, enclosing the self-filtering light source 20 within the reflector 21. The sixth embodiment shares the same structure and configuration as the fifth embodiment, as described above.

[0100] Referring to Figure 18, the skin beautification instrument 1000 of the seventh embodiment of the present application is a skin beautification mirror. The light source 20 with its own filtering function used therein is different from the fifth and sixth embodiments in that the skin beautification mirror of this embodiment is provided with a radio frequency component or an EMS component. The radio frequency component or EMS component includes a radio frequency electrode assembly or EMS electrode assembly 90 connected to the radio frequency / EMS circuit board inside the housing 10 (or integrated in the main control board 40) and the front end face of the skin beautification mirror. The radio frequency / EMS electrode assembly 90 is electrically connected to the main body of the skin beautification instrument in a contact or pin / tab manner. In this embodiment, the radio frequency / EMS circuit board is integrated on the main control board 40. The main control board 40 is used to control the operation of the skin beautification instrument 1000. Functional modules such as a control unit, a DC power supply module, a light source control module, and a radio frequency drive module are integrated on the main control board 40. The RF / EMS electrode assembly 90 includes an electrode holder 81 and one or more RF / EMS electrodes 92 mounted on the electrode holder 91. Each pair of RF / EMS electrodes 92 has positive and negative electrodes 93 at their ends, and the positive and negative electrodes 93 are electrically connected to the main control board 40 via wires 95. For example, a number of magnets 94 can also be mounted on the holder 91, and a number of magnets 94 are correspondingly mounted in the front shell 11 of the skin beauty instrument, forming a magnetic attraction between the RF / EMS assembly 80 and the main body 100 of the skin beauty instrument. A mounting hole 910 is provided on the holder 91, and the RF / EMS electrode 92 is adapted to and embedded in the mounting hole 910. In this embodiment, the photon skin beauty and RF / EMS functions can be activated through a key group, and RF-assisted treatment can be obtained simultaneously during photon skin beauty, and different light bands + RF treatment can be achieved. The working principle of RF / EMS is the same as that of the previous embodiment. The structure and configuration of the sixth embodiment that are the same as those of the fifth and sixth embodiments refer to the previous embodiment.

[0101] The skin beautifying devices of the fifth to seventh embodiments of the present application have a light-transmitting panel approximately the same size as the front end of the skin beautifying device and a large mirror surface, which can achieve large-area full-body skin beautification, making it quicker and more efficient to use. When using the device, hold the light-transmitting panel / transparent crystal surface against the skin.

[0102] Referring to Figures 19-25 , the eighth embodiment of the present application is a beauty mask comprising a housing 10, a main control board 40 disposed within the housing 10, and a light source unit. The light source unit comprises a light source 20 and a reflector 21. A light-transmitting panel 12 is disposed at the front end of the housing 10, forming a light outlet. The light-transmitting panel 12 is disposed in front of the housing 10 and encloses the light source within the space between the housing 10 and the reflector 21. The light source 20 is electrically connected to the main control board 40.

[0103] The light source 20 of this embodiment has a built-in filtering function, with the light source and filter film being an integrated design. Specifically, the light source includes a transparent lampshade (e.g., a bulb or tube) and a light-emitting element (e.g., a filament) within the lampshade. The filter film is integrally attached to the transparent lampshade, which filters out light waves in a predetermined wavelength range. Light emitted by the light source 20 is filtered by the built-in filter film to obtain light waves in the desired wavelength range. This light passes through the light outlet and illuminates the skin surface. For example, light emitted by the light source is filtered by the filter film to obtain light waves in the 500-1800nm ​​or 900-1800nm ​​wavelength range, which acts on the skin for cosmetic or therapeutic treatment.

[0104] A filter film can be formed on the surface of a transparent lampshade through an optical coating process. Because the lampshade surrounds the light source, all light emitted by the light-emitting elements within the transparent lampshade is filtered by the filter film before being emitted. The light emitted by the light source has the desired wavelength after filtering. The optical coating process can be used to prepare a filter, which is a prior art technique for optical coating on a transparent substrate. This application uses a transparent lampshade as a carrier transparent substrate for the coating process. The same coating process used to prepare the filter is used to coat the surface of the transparent lampshade, forming an integrated structure of the filter film and the light source, thereby obtaining a light source with a built-in filtering function.

[0105] Examples of optical coating processes include evaporative deposition, ion beam sputtering (IBS), plasma sputtering, and atomic layer deposition (ALD). In some embodiments, a coating layer is formed on a transparent lampshade using an optical coating process. A single-band optical filter that passes a single wavelength band is formed by single-band coating, such as a single-band optical filter that passes wavelengths of 500-1800 nm, 900-1800 nm, and 500-600 nm. Alternatively, a multi-band optical filter that passes two or more wavelength bands simultaneously is formed by multi-band coating, such as a dual-band optical filter that passes wavelengths of 500-600 nm and 900-1800 nm by dual-band coating. Alternatively, a multi-zone optical filter that passes wavelengths of 900-1800 nm and 500-600 nm is formed by zone coating on the transparent lampshade. For example, a zone coating may include a filter having a wavelength range of 500-600 nm and a wavelength range of 900-1800 nm. The filter film with zoned coating can be switched between different zones by rotating the light source to obtain light of different wavelengths. The rotating light source can be driven by installing a rotating structure at both ends of the light source, such as a gear / rack / motor to drive the rotation of the light source.

[0106] It is also possible that a filter film prepared by existing technology is coated on the surface of the light source (i.e., the surface of a transparent cover of the light source such as a light bulb or a gun barrel) to form a light source with its own filtering function, and the filter film and the light source are designed as one.

[0107] The beauty mask of this embodiment has three (not limited to three) light sources 20 arranged side by side inside. They can be IPL light sources, tungsten filament light sources, or carbon fiber light sources. Of course, other applicable light sources such as LED light sources can also be used.

[0108] The light emitted by the light source 20 is filtered by the filter film coated on the transparent lampshade to obtain light of the desired wavelength band. It is directly reflected by the reflector 21 and then passes through the light-transmitting panel 12 to illuminate the skin for treatment / beautification. The emission direction is the front direction of the housing 10, and area a in the figure is the light emission area. The front direction is the direction toward the face of the user wearing the beauty mask. The light from the light source 20 is emitted from the front direction and illuminates the face of the user wearing the beauty mask.

[0109] The front of the housing 10 may have a curvature adapted to the human face as shown in Figures 19 to 24. In other embodiments, the front of the housing may be flat or comprised of multiple faces at angles to each other. In this embodiment, the present application is implemented as a wearable mask. In other embodiments, the present application may be placed on a desktop for use or used in a handheld manner.

[0110] The light source of this application, which has a built-in filtering function, allows light of specific wavelengths to pass through while filtering out light of other wavelengths. The light emitted by the light source is light of a specific wavelength band suitable for skin treatment or beauty. The corresponding wavelength band is selected according to the purpose and effect of the treatment or beauty treatment. As for which wavelength band should be selected to correspond to the symptoms and treatment / beauty treatment plan, it is a matter for the treatment or beauty treatment user or physician to consider and is also within the knowledge of the beauty industry. It does not affect the implementation and technical effect of the technical solution of this application. This application provides a device that can be used for such treatment / beauty treatment. After determining the wavelength band required for the treatment / beauty treatment plan, the beauty mask of this application and its corresponding light source with built-in filtering function are used.

[0111] This cosmetic mask is a non-contact cosmetic procedure. It uses a large, full-face illumination to simultaneously cover all facial areas, including those with hidden corners like the nose and lips. This full-face illumination maximizes facial skin treatment consistency, significantly enhancing the overall benefits of whitening, rejuvenation, and collagen regeneration. Furthermore, compared to commercial photorejuvenation devices, which each flash only targets a small area of ​​skin and require dozens or even hundreds of flashes to cover the entire face, this device uses only a single flash, significantly reducing usage time. Each flash (0.2-3 seconds) is equivalent to a single flash of a commercial photorejuvenation device (approximately 3-5 minutes). If this device can deliver 30 flashes per session, the results are dozens of times greater than those of a conventional photorejuvenation device. This device utilizes a mask for treatment / cosmetics. Simply turning on the light source delivers the desired wavelengths of light, which are then applied directly to the face for treatment / cosmetics, making it extremely convenient to operate.

[0112] For example, the light source 20 of the light source unit adopts three vertically arranged IPL lamp tubes, or an IPL lamp tube plus a halogen lamp tube, which are installed in the reflector 21. The reflector 21 reflects the light of all light sources 20. In this embodiment, each light source 20 corresponds to a reflector. The reflector 21 can be three reflectors connected into a whole, or a reflector formed on an integral structure corresponding to the light source. The shape of each reflector 21 is an arc surface arranged around the corresponding light source 20. Specifically, the arc surface of the reflector 21 extends along the circumference of the light source 20 and is arranged with the light source 20 as the center, so as to more efficiently reflect the light emitted backward by the light source 20 to the front direction of the mask. It is understandable that the reflector 21 can also be an integral structure, forming three arc shapes corresponding to the rear of the three lamp tubes.

[0113] The beauty mask also includes a heat sink 22, located behind the reflector 21 and matching its shape, or integral with the reflector 21. The heat sink 22 can be a heat sink, or a combination of a heat pipe, a temperature-vaporizing plate, a superheat pipe, a superheat plate, or a heat-conducting substrate made of a single thermally conductive material (such as aluminum or copper). Heat dissipation from the light source 20 can also be achieved by using a fan to blow / suction air instead. The beauty mask also includes a rear housing 15, which mates with the outer housing 10 to form a cavity that accommodates the light source 20, the reflector 21, and the heat sink 22. The rear housing 15 is located at the rear of the beauty mask, opposite the front of the mask and facing away from the user's face when the mask is worn. Ventilation holes 101 are provided on the rear housing 15, communicating with the cavity to facilitate heat dissipation and cooling.

[0114] The beauty mask further includes a head stopper 17 , which is fixedly mounted or detachably arranged on the front side of the shell 10 , so as to facilitate the user to wear and position the mask and maintain a certain safe distance.

[0115] The beauty mask further comprises a retractable belt 18. The retractable belt 18 is used to surround the user's head and help fix the beauty mask when the beauty mask is worn. The retractable belt 18 has a retractable adjustment structure, or the retractable belt 18 is elastic and can be applied to different users.

[0116] The beauty mask is also provided with a button group, which is electrically connected to the main control board 40.

[0117] As shown in Figure 23, the beauty mask also includes a main control board 40 within the outer shell 10. The light source 20 is connected to the main control board 40. In this embodiment, the main control board is shown as being located within the outer shell 10. In other embodiments, the main control board can be located outside the beauty mask and connected to power via a socket during use. The power supply assembly includes a power port and / or a battery 30. For example, the outer shell 10 (front shell 11 or rear shell 15) is provided with a through-hole mounted power port electrically connected to the main control board 40, thereby electrically connecting to an external power source for power. The battery 30 can be located in the cavity between the outer shell and rear shell, or in an external power socket 31, connected to the power port via a power cord or plug-in connection. In other embodiments, the battery may not be provided, and the beauty mask may be powered directly via the power port. For example, referring to Figures 24-25, the power socket 31 contains the battery 30 and a power circuit board 34, which are electrically connected. The power supply interface of the beauty mask and the power circuit board 34 can be connected through a power line.

[0118] When using the beauty mask, the user can wear the beauty mask on the face and turn on the light source by operating the button group. The light emitted by the light source 20 is filtered by the built-in filter film to obtain the light wave of the expected band, which passes through the transparent panel 12 and illuminates the skin surface for beauty or treatment.

[0119] 26-27 , a ninth embodiment of a beauty device 1000 of the present application is a beauty mirror, comprising a housing 10, a main control board 40 disposed within the housing 10, and a light source and power supply assembly electrically connected to the main control board 40. The housing 10 has a large window formed at the front end thereof, connected to a frame-like front shell 11. The housing 10 has a cavity formed therein, and a large window is formed at the front end of the beauty mirror. A light-transmitting mask 12 is mounted within the large window, forming a large light outlet or mirror.

[0120] The light source unit includes a light source 20 and a reflector 21 mounted thereon. The reflector has a large opening at its front end, which is covered by a translucent panel 12, thereby enclosing the light source 20 within the reflector 20. Light from the light source 20 has a built-in filtering function. After being filtered by a filter film on its surface, it is reflected by the reflector 21 and passes through the translucent panel 12 to illuminate the skin.

[0121] In this embodiment, the light source 20, which has a built-in filtering function, is designed with an integrated filter film. Specifically, the light source includes a transparent lampshade (e.g., a bulb or tube) and a light-emitting element within the lampshade. The filter film is integrally attached to the transparent lampshade to filter out light in non-desirable wavelengths. Light emitted by the light source 20 is filtered by the built-in filter film to obtain wavelengths in the desired range. This light is then emitted from the light outlet and applied to the skin surface. For example, light emitted by the light source is filtered by the filter film to obtain wavelengths in the 500-1800nm ​​or 900-1800nm ​​range, which acts on the skin for cosmetic or therapeutic treatment.

[0122] A filter film can be formed on the surface of a transparent lampshade through an optical coating process. Because the lampshade surrounds the light source, all light emitted by the light-emitting elements within the transparent lampshade is filtered by the filter film before being emitted. The light emitted by the light source has the desired wavelength after filtering. The optical coating process can be used to prepare a filter, which is a prior art technique for optical coating on a transparent substrate. This application uses a transparent lampshade as a carrier transparent substrate for the coating process. The same coating process used to prepare the filter is used to coat the surface of the transparent lampshade, forming an integrated structure of the filter film and the light source, thereby obtaining a light source with a built-in filtering function.

[0123] Examples of optical coating processes include evaporative deposition, ion beam sputtering (IBS), plasma sputtering, and atomic layer deposition (ALD). In some embodiments, a coating layer is formed on a transparent lampshade using an optical coating process. A single-band optical filter that passes a single wavelength band is formed by single-band coating, such as a single-band optical filter that passes wavelengths of 500-1800 nm, 900-1800 nm, and 500-600 nm. Alternatively, a multi-band optical filter that passes two or more wavelength bands simultaneously is formed by multi-band coating, such as a dual-band optical filter that passes wavelengths of 500-600 nm and 900-1800 nm by dual-band coating. Alternatively, a multi-zone optical filter that passes wavelengths of 900-1800 nm and 500-600 nm is formed by zone coating on the transparent lampshade. For example, a zone coating may include a filter having a wavelength range of 500-600 nm and a wavelength range of 900-1800 nm. The filter film with zoned coating can be switched between different zones by rotating the light source to obtain light of different wavelengths. The rotating light source can be driven by installing a rotating structure at both ends of the light source, such as a gear / rack / motor to drive the rotation of the light source.

[0124] It is also possible that a filter film prepared by existing technology is coated on the surface of the light source (i.e., the surface of a transparent cover of the light source such as a light bulb or a gun barrel) to form a light source with its own filtering function, and the filter film and the light source are designed as one.

[0125] The light source 20 can be an IPL light source, a tungsten filament light source, or a carbon fiber light source. Of course, other suitable light sources such as LED light sources can also be used. For example, the light source 20 uses an IPL lamp tube and a halogen lamp; alternatively, the light source 20 uses an IPL lamp tube and one or two halogen lamps, or uses two IPL lamp tubes and a halogen lamp, etc.

[0126] The light-transmitting panel 12 in this embodiment is a convex lens, which is used to transmit light waves, ensuring more uniform illumination of the face. Utilizing the principle of convex lenses, the divergent light is refracted through the lens and evenly emitted toward the light-emitting area. The light-transmitting panel / convex lens 12 in this embodiment utilizes a large, full-surface illumination, simultaneously covering all areas of the face, including blind spots like the nose and lips. Full-surface illumination maximizes the consistency of facial skin treatment, significantly improving the overall whitening and rejuvenation effects. Full-surface illumination covers the entire face, significantly reducing usage time.

[0127] The light emitted by the light source 20 is filtered by the filter film covered on the transparent lampshade to obtain light of the desired wavelength band, which is directly reflected by the reflective element 21 and then passes through the light-transmitting panel 12 to illuminate the skin for treatment / beautification.

[0128] A heat sink 22 is also installed within the housing 10. The heat sink 22 is positioned behind the reflector 21 and matches its shape, or it may be integrally formed with the reflector 21. The heat sink 22 may be a heat sink, or may be a combination of a heat pipe, a vapor chamber, a superheat pipe, a superheat plate, or a thermally conductive substrate made of a single thermally conductive material (such as aluminum or copper). Heat generated by the light source is rapidly transferred from the reflector 21 to the heat sink 22. Cooling from the light source 20 can also be achieved by fan-assisted ventilation. Ventilation holes 101 are provided in the housing 10, connecting to the internal cavity, to facilitate heat dissipation from the heat sink 22 and the reflector 21.

[0129] In this embodiment, through holes are provided on the reflective element 21 and the heat sink 22 for the wires or connectors electrically connecting the light source 20 and the main control board to pass through.

[0130] The power supply assembly includes a power interface and / or a battery 30. For example, the housing 10 is provided with a power interface that is electrically connected to the main control board 40 through a through hole, so as to be electrically connected to an external power source to provide power. The battery 30 can be set in the housing 10, or it can be set in an external power socket 31, connected to the power interface via a power cord or electrically connected in a plug-in manner. In other embodiments, a battery may not be provided, and the beauty mirror can be powered directly through an external power source connected to the power interface. For example, the power socket 31 is provided with a battery 30 and a power circuit board 34, and the two are electrically connected. The power interface of the beauty mirror and the power circuit board 34 can be connected via a power cord.

[0131] For example, a connecting frame 61 may be provided between the power socket 31 and the housing 10. A ventilation channel communicating with the interior cavity of the housing 10 is provided within the connecting frame 61. A fan 60 is also provided within the connecting frame. The housing 10 of the beauty mirror is provided with ventilation holes 101. The fan 60 blows / sucks air to cool the reflector 21 and heat sink 22 of the light source.

[0132] The beauty mirror is also provided with a button group, which is electrically connected to the main control board 40.

[0133] To use the beauty mirror, hold it toward the user's face and activate the light source by operating the button assembly. Light from the light source 20 is filtered by the filter membrane on the transparent lampshade to obtain the desired wavelength. The emitted light waves pass through the light-transmitting panel / convex lens 12 and illuminate the skin surface for beauty or treatment. This embodiment of the beauty mirror uses a large, full-surface light output to simultaneously cover all areas of the face, including hard-to-reach areas such as the nose and lips. This full-surface illumination maximizes the consistency of facial skin treatment and significantly enhances the overall whitening and rejuvenation effects of the facial skin.

[0134] The beauty devices of the various embodiments described above use a light source with a built-in filtering function, which has a simpler structure, reduces the number of filters, saves filter materials, and saves costs such as assembly and maintenance. The light emitted by the light source is filtered before being emitted, and the filtering eliminates ultraviolet rays and light / heat damage to surrounding components caused by intercepted photons. The opening of the reflector is connected to the light-transmitting panel, and the light source reflector can be designed with the light source to form a complete light output channel. The light emitted by the light source is projected from the reflective cup to the light outlet, shortening the distance between the light source and the light outlet and improving the output of light energy. After removing the independent filter, there is no space for photons to leak sideways, effectively improving the output of light energy.

[0135] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of protection of the present application is defined by the appended claims and their equivalents.
