These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section.

Please refer to Figures 1-27, the present application relates to a beauty device 1000, including a housing and a main control board installed in the housing, and a light source part and a power supply component electrically connected to the main control board. The front face of the beauty device forms a light outlet. The light outlet can be formed by a transparent panel 12 set in the front opening of the housing, or it can be formed by an opening. The light source 20 includes a light source and a reflector 21 for installing the light source; the light source and the filter film adopt an integrated design, specifically, the light source includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade, and a filter film is integrally attached to the transparent lampshade. The filter film can filter out light waves of a predetermined band, so that the light generated by the light-emitting element is filtered by the filter film on the light source lampshade to obtain an output light of a predetermined band, which is emitted from the light outlet to act on 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 a filter film to obtain light in the wavelength bands of 500-1800nm and 900-1800nm, which acts on the skin for beauty or treatment.

The filter film can be formed on the surface of the transparent lampshade through a coating process. Since the lampshade surrounds the light source, all the light emitted by the light-emitting element is first filtered to obtain the light waves of the expected band before being emitted by the light source. The filter can be prepared by an optical coating process, which is to perform optical coating on a transparent substrate. This technology is a prior art. The present application uses a transparent lampshade as a carrier transparent substrate for the coating process, and adopts the same coating process as the preparation of the filter to coat the surface of the transparent lampshade to form an integrated structure of the filter film and the light source, thereby obtaining a light source with a self-contained filtering function.

Example coating processes include evaporation deposition, ion beam sputtering (IBS), plasma sputtering, atomic layer deposition (ALD), etc. as described below. In evaporation deposition, the source material in the vacuum chamber is heated or bombarded with an electron beam to evaporate. The vapor condenses on the surface of the transparent lampshade to form a uniform filter film. Evaporation is relatively mild and can make the coating loose or porous. In the ion beam sputtering (IBS) process, a high-energy electric field can accelerate the ion beam. This acceleration gives the ions significant kinetic energy. When colliding with the source material, the ion beam will "sputter" the atoms of the target material. These sputtered target ions (atoms become ions under the influence of the ionization zone) also have kinetic energy and will produce a dense film when in contact with the surface of the transparent lampshade. The plasma sputtering process is a general term for a series of technologies, such as plasma sputtering and magnetron sputtering, in which the ions in the plasma are accelerated into the source material, collide with the loose energy source ions, and then sputter onto the transparent lampshade to form 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.

In some embodiments, a coating layer is formed on a transparent lampshade according to the above coating process; wherein, a single-band filter film that passes a single band is formed by single-band coating, such as a single-band filter film that passes 500-1800nm, 900-1800nm, and 500-600nm; or, a single-band filter film that passes two or more bands at the same time is obtained by multi-band coating, such as a dual-band filter film that passes 500-600nm+900-1800nm obtained by dual-band coating; or, a multi-zone filter film that passes multiple bands in different zones is obtained by zone coating on the transparent lampshade, for example, the filter film obtained by zone coating has zone A: 500-600nm; zone B: 900-1800nm. The filter film with zone coating can switch different zones of the filter film by rotating the light source to obtain light of different 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.

In other embodiments, a filter film prepared by existing technology may be coated on the surface of a light source (i.e., a transparent cover of the light source such as a light bulb or a barrel) to form a light source with a built-in filtering function, and the filter film and the light source may be designed as an integrated whole.

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

Among them, tungsten filament light source or carbon fiber light source uses tungsten filament or carbon fiber as filament, i.e. luminous material. The filament is installed in a bulb (lamp tube) and emits light after being energized. The bulb (lamp tube) is kept in a vacuum, or filled with low-pressure inert gas or halogen gas to prevent the filament from oxidizing under high temperature. When the bulb (lamp tube) of a tungsten filament light source or carbon fiber light source is filled with halogen gas such as iodine or bromine, a halogen lamp (also called tungsten halogen lamp) is obtained. Tungsten filament light source or carbon fiber light source belongs to incandescent lamp, which is realized by using the structure of incandescent lamp.

Using tungsten wire and/or carbon fiber as the light-emitting material, i.e., filament, a certain proportion of inert gas or halogen gas can be filled in the bulb (lamp tube) to increase the life of the light source. The spectral distribution of the tungsten wire and/or carbon fiber lamp can be changed by adjusting the gas pressure, gas ratio, current pulse or supply voltage in the lamp.

Tungsten filament light source or carbon fiber light source has full spectrum characteristics and constant light characteristics. The light source produces full spectrum light, including visible light and invisible light; after filtering by the filter film, light of the predetermined wavelength band is obtained to beautify or treat the skin. For example, visible light of 500-600nm can dilute epidermal melanin, and near-infrared light of 900 to 2500nm can directly reach the dermis and basal layer, stimulate collagen regeneration, and repair the basal layer.

The following is a specific application example of a beauty device using the above-mentioned light source with built-in filtering function of the present application, which 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.

Referring to Figures 1-4, the beauty device 1000 of the first embodiment of the present application is a handheld light skin beauty instrument, including a shell, a cavity is formed inside the shell, and a light outlet of the skin beauty instrument is arranged at the front end of the shell. The light outlet of the skin beauty instrument in this embodiment is a relatively small area, such as a light outlet of 1-4 square centimeters, which is used for hair removal or skin beauty or treatment. The front end of the shell 10 is connected to the front shell 11, and the rear end is connected to the rear shell 15. The transparent panel 12 installed inside the opening at the front end of the shell 10 is a transparent crystal (with the same label 12), and the opening is covered to form the light outlet of the skin beauty instrument, and the rear end of the shell is covered by the rear shell 15. The light source part, power supply component, main control board 40, fan 60, semiconductor refrigeration component 80, heat dissipation component 70 and other components are installed in the shell. Among them, the transparent crystal 12 is independently arranged, and the transparent crystal 12 is cooled by the semiconductor refrigeration component 80, or the transparent crystal 12 is the transparent crystal cold surface of the semiconductor refrigeration component (refer to Figure 5).

The light source unit includes a light source 20 and a reflector 21. The 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. The light source 20 includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade. A filter film is integrally attached to the transparent lampshade. The filter film can filter out light waves of a predetermined band, so that the light generated by the filament is filtered by the filter film on the lampshade to obtain an output light of a predetermined band, which is emitted from the light outlet to act on the skin surface for beauty or treatment. The light source 20 of this embodiment is a light source with a built-in filtering function, and the light source and the filter film are designed in an integrated manner.

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

In conjunction with the light source portion shown in FIG6 , a cavity is formed inside the reflector 21 for mounting the light source 20 and forming a light outlet channel 212. The reflector 21 includes an arc-shaped (not limited to an arc-shaped) rear cover 210 and a front cover 211 forming the light outlet channel 212; the front cover 211 is connected to the front cover 210 as a whole or as an integrated structure. A light outlet channel 212 is formed inside the front cover 211, and its front end is open, connected to the light outlet of the front end face of the skin beauty instrument or abuts against the transparent crystal (translucent panel) 12. The rear cover of the reflector 21 is adapted to the shape of the light source 20, surrounds the light source 20, and the light source 20 is installed in the rear cover. The inner wall of the reflector is reflective, so that the light emitted by the light source 20 is reflected forward from the inner wall of the rear cover 210, and reflected on the inner wall of the front cover 211, so that all light waves are projected from the light outlet channel 212 to the light outlet. The arrow lines in Figure 6 indicate the reflection and emission directions of the light waves. The light source part 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 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/photothermal damage to the surrounding components caused by intercepted photons have been eliminated in the emitted light. The light emitted by the light source is directly projected to the light outlet through the reflector 21, which shortens the distance between the light source and the light outlet and improves 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, which effectively improves the output of light energy.

A heat insulation board 14 is also installed inside the shell 10. The heat insulation board 14 is adapted to the inner wall of the shell to form a relatively closed space between the inner wall of the shell to install the main control board 40 to protect the main control board 40. The lamp holder bracket 13 and the heat insulation board 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 shell (shell 10 and/or front shell 11 and/or rear shell 15) as the air inlet and outlet of the skin beauty instrument, which are connected to the air flow in the air duct in the shell to form a heat dissipation duct. A button hole is provided on the shell to install a button group 42. A through hole is provided on the rear shell 15 to install a power interface 41.

The main control board 40 is electrically connected to the button group 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 provided with corresponding circuits and functional modules according to functional requirements. These circuits or functional modules can adopt existing technologies or purchase corresponding electronic components from the market. For example, the main control board 40 is provided with a power module, multiple control modules, a radio frequency/EMS drive module, a temperature control module, etc.

The power supply assembly includes a battery 30 and/or a power supply interface 41. The battery 30 can be a rechargeable battery that is charged through the power supply interface 41; it can also be a disposable battery that can be replaced; or, the battery 30 is not provided, and the power supply is directly connected to an external power source through the power supply interface 41.

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

In this embodiment, the light-transmitting panel installed at the front end of the skin-beautifying instrument is a transparent crystal 12 and forms a light outlet, and the transparent crystal 12 is cooled by a semiconductor refrigeration element 80. The transparent crystal 12 and the semiconductor refrigeration element 80 are adapted in shape, and the semiconductor refrigeration element 80 cools the periphery of the transparent crystal 12, that is, the periphery of the light outlet. The transparent crystal 12 is a whole transparent crystal and can be in contact with the skin.

The semiconductor cooling element 80 is also called a thermoelectric cooler (TEC) or a heat pump or a Peltier cooler; it includes a semiconductor particle layer 82 in the middle and a hot surface 83 and a cold surface 81 at both ends, and also includes a pair of positive and negative electrodes to electrically connect the circuit of the semiconductor cooling element with a control module disposed on the main control board 40 or an independently disposed control board, and the independent control board is electrically connected to the main control board 40. The two ends of the electric particle layer are a cold end and a hot end; a cold end circuit is disposed on the cold surface 81, and a hot end circuit is disposed 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 to form the internal circuit of the semiconductor cooling element, and a temperature difference is formed between the cold surface 81 and the hot surface 83 after power is turned on.

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

For example, the semiconductor refrigeration element 80 is annular as a whole, the hot surface 83 and the cold surface 81 are matched rings, and the semiconductor particle layer 82 is arranged in a matched ring. The through hole in the middle of the ring is for the light wave emitted by the light source, that is, the light source 20 to pass through. The hot surface 83/cold surface 82 is a substrate made of a heat-conducting material or other types of heat transfer structural parts, for example, it can be made of a single heat-conducting material such as aluminum/copper/graphene, or it can be a heat pipe/temperature averaging plate VC/super heat pipe or super heat conductive plate such as ALVC (aluminum superconducting tube or aluminum superconducting plate) and other heat transfer structural parts that use phase change (evaporation and condensation) to quickly conduct heat or cold. The annular semiconductor refrigeration element 80 is arranged on the rear surface (back side) of the transparent crystal 12, and the annular cold surface 82 is attached to the edge of the transparent crystal 12 to cool the surrounding of the transparent crystal 12, so that the entire transparent crystal 12 is cooled. The transparent crystal 12 is clamped and installed by the front shell 11, and the semiconductor refrigeration element 80 is also installed in the front shell 11.

In other alternatives, referring to FIG. 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, and there is no need to set up the transparent crystal 12 separately. The transparent crystal cold surface 12/81 is sealed on the light outlet, and the semiconductor cooling element 80 is clamped and installed by the front shell 11. The transparent crystal cold surface can contact the skin. The semiconductor particle layer 82 and the hot surface 83 can be set in a ring shape and welded to the edge ring band of the transparent crystal cold surface 81.

A heat dissipation assembly 70 is also installed in the housing 10 for dissipating heat from the semiconductor refrigeration element 80. The heat dissipation 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 by rapid heat transfer, and the other end is connected to the hot surface 83 of the semiconductor refrigeration element 80 by rapid heat transfer, so as to quickly transfer the heat of the hot surface to the heat sink 71 for heat dissipation. The shapes of the two ends of the heat conductor are designed based on the principle of rapid heat transfer. For example, the front end is set to be annular, and the heat transfer is carried out in a maximum contact area with the annular hot surface 83. The rear end is a straight rod, which is inserted into a group of parallel heat sinks 71 and contacts with the heat sink 71 for heat transfer. In other embodiments, the front end may also be bent, and the heat conductor is L-shaped as a whole; it may also be other shapes. The heat conductor 72 is a heat transfer structure, which may be made of a single heat conductive material such as aluminum/copper/graphene, or may be a heat pipe/heat averaging plate VC/super heat pipe or super heat conductive plate such as ALVC (aluminum superconducting tube or aluminum superconducting plate) and other components that utilize phase change (evaporation and condensation). The heat sink 71 is preferably located behind the ventilation holes on the housing to facilitate air cooling and heat dissipation.

The fan 60 can be installed 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 elevation housing, as the air inlet/outlet of the fan.

The beauty 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 electrode is a group of columnar electrodes, and a through hole is correspondingly arranged on the periphery of the transparent crystal 12 and/or the semiconductor refrigeration component 80. One end of the radio frequency/EMS electrode 90 is installed in the through hole, and the front end is exposed outside the transparent crystal 81/12 to contact the skin, and the rear end is electrically connected to the main control board 40 or to an independently arranged radio frequency/EMS control board. The main control board 40 or the radio frequency/EMS control board is provided with functional modules such as a control module, a power module, and a radio frequency/EMS driving module. When the radio frequency/EMS control board is independently arranged, 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 the power module on the main control board 40. In other embodiments, the radio frequency/EMS control board can also be integrated on the main control board 40. The RF/EMS electrode 90 can be in the shape of a bar, a column, an arc, a ring, or any other suitable shape. The RF/EMS electrode 90 and the light outlet can be overlapped or arranged around the light outlet, and more than one pair can be arranged. The rear end of each pair of RF/EMS electrodes forms the positive and negative electrodes of RF/EMS, 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 a step-up transformer. The output control module outputs the RF/EMS current to the user's skin through the RF/EMS electrode 90, and performs RF/EMS treatment or RF/EMS beauty treatment 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.

In this embodiment, multiple pairs of RF/EMS electrodes 90 are installed in the through holes set on the transparent crystal 12 and the semiconductor refrigeration element 80, and electrode points are formed on the outer surface of the transparent crystal 12, and the positive and negative electrodes are electrically connected to the main control board 40. The transparent crystal 12 and the semiconductor refrigeration element 80 are installed in a close fit and are both installed in the front shell 11. The front end of the heat-conducting element 72 of the heat dissipation assembly 70 is annularly abutted against the annular heat surface of the semiconductor refrigeration element 80. The heat sink 71 is installed behind the ventilation hole 101 of the shell 10. The ventilation hole 101 is a group of fine through holes, which are connected to the heat sink 71 by air flow; the fan 60 can be arranged up and down with the heat sink 71, and the air ducts of the two are connected by air flow. The light source part is installed on the lamp holder bracket 13, which is located inside the front end of the shell 10. The light source is the light source 20, which is installed in the reflector 21. A heat dissipation air duct can be formed in the reflector to dissipate the heat of the light source, and a heat sink can also be arranged outside the reflector to dissipate the heat of the reflector. The front end of the reflector 21 is a light outlet channel 212. A battery 30 is installed inside the rear end of the housing. The button group 42 is used to turn on the device and start the light source. The light emitted by the light source 20 is a light wave of a predetermined band obtained after filtering by a filter film designed as an integral part of the light source. The light is projected from the light outlet channel 212 to the light outlet port to act on the skin for photon beauty. The RF/EMS function is activated by the button group 42, and the RF/EMS electrode 90 generates a RF/EMS current to act on the skin for RF/EMS therapy. The RF/EMS function can be turned on at the same time as the photon beauty function or one of them can be turned on selectively. The heat dissipation component 70 dissipates heat from the semiconductor refrigeration component 80, and the cold surface of the semiconductor refrigeration component 80 cools the transparent crystal 12, and the transparent crystal 12 contacts the skin; or the cold surface of the transparent crystal of the semiconductor refrigeration component 80 contacts the skin. Under the action of the fan 60, the ventilation holes provided on the housing of the skin beauty instrument inhale cold air to cool the heat sink 71 and the light source.

Referring to FIG. 7 , the beauty device 1000 of the second embodiment of the present application is also a handheld skin beautifying device. The difference from the first embodiment is that no RF/EMS component is provided, that is, no RF/EMS electrode 90 and RF/EMS control board are provided (or no functional module corresponding to the RF/EMS component is provided on the main control board 40). The other structures and functions are the same as those of the first embodiment, and the above embodiment is directly referenced in the specific implementation.

Based on the transformation of the first and second embodiments, one or more semiconductor refrigeration components 80 are arranged on the side of the transparent crystal 12 to cool the transparent crystal 12. The shape of the one or more semiconductor refrigeration components 80 is adapted to the side shape of the transparent crystal 12, and the cold surface 82 of the semiconductor refrigeration component 80 fits the side of the transparent crystal 12, and is in close contact to quickly cool the transparent crystal 12. The transparent crystal 12 covers the light outlet at the front end of the beauty instrument. The other structures are the same as the first and second embodiments, and the description of the above embodiments is directly quoted during the specific implementation.

Referring to Figs. 8-9, the beauty device 1000 of the third embodiment of the present application is also a handheld skin beautifying device. The difference from the first embodiment is that the light source part of the present embodiment adopts dual light sources 20, 20', which are arranged side by side and installed in the reflector 21 at the same time, and project light to the light outlet through the light outlet channel 212 in the front end of the reflector 21. For example, the dual light source can adopt one or more of an IPL light source, a tungsten light source or a carbon fiber light source. Each light source 20 includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade. A filter film is integrally attached to the transparent lampshade. The filter film can filter out light waves of a predetermined wavelength band, so that the light emitted by the light source is a light wave of a predetermined wavelength band obtained after filtering by the filter film on the lampshade, and is emitted from the light outlet to act on the skin surface for beauty or treatment. Each light source 20 of the present embodiment is a light source with a self-filtering function, and the light source and the filter film are designed in an integrated manner. The other structures of the beauty device of the present embodiment are the same as those of the first embodiment, and the description of the first embodiment can be directly cited during implementation.

When in use, the button group 42 is turned on to start the light sources 20 and 20'. For example, the two light sources are halogen lamps and/or IPL lamps. The light waves emitted by the light sources 20 and 20' are light waves of a predetermined band obtained by filtering the light filter membranes provided therewith, and then pass through the light outlet port (transparent crystal 12) through the light outlet channel 212 in the reflector to act on the skin for photon beauty and treatment. The RF/EMS function is activated by the button group 42, and the electrode points formed by the RF electrode or EMS electrode 90 on the front end surface of the skin beauty instrument generate RF or EMS current to act on the skin for RF/EMS therapy. The RF/EMS function can be turned on at the same time as the photon beauty and treatment function or one of them can be turned on selectively. The heat dissipation component 70 dissipates heat for the semiconductor refrigeration component 80, and the cold surface of the semiconductor refrigeration component 80 cools the transparent crystal 12, and the transparent crystal 12 contacts the skin to form an ice compress or pre-cooling. The ventilation holes 101 on the skin beauty instrument housing draw cold air into the interior to cool the heat sink 71 and the light source, and the fan 60 strengthens the air flow to promote the heat dissipation speed.

In this embodiment, the annular semiconductor cooling element 80 is attached to the back of the transparent crystal 12 to cool the periphery of the light outlet; or, the transparent crystal 12 and the semiconductor cooling element 80 are an integral structure, the transparent crystal is the cold surface of the semiconductor cooling element, the intermediate galvanic particle layer 82 and the hot surface 83 of the semiconductor cooling element are annular, and the cold surface 12/81 of the transparent crystal is in direct contact with the skin for cooling; or, one or more semiconductor cooling 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 cooling elements 80 cool the light outlet from the side of the transparent crystal 12; or, the transparent crystal 12 is a common cold surface for one or more semiconductor cooling elements, and the transparent crystal (light-transmitting panel) 12 is directly used as the cold surface of one or more semiconductor cooling elements, and the light outlet is formed at the same time.

Referring to FIG. 10 , the beauty device 1000 of the fourth embodiment of the present application is the same as the third embodiment, and is also a handheld skin beauty instrument using dual sources. Each light source 20 includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade. A filter film is integrally attached to the transparent lampshade. The filter film can filter out light waves of a predetermined band, so that the light waves emitted by the light source 20 are obtained after filtering by the filter film with the light filter, and are emitted from the light outlet to act on the skin surface for beauty or treatment. Each light source 20 of this embodiment is a light source with a built-in filter function, and the light source and the filter film are designed in an integrated manner. The difference between this embodiment and the third embodiment is that no RF/EMS component is configured, and it does not have RF/EMS function. The other structures of this embodiment are the same as those of the third embodiment or the other embodiments mentioned above, and the description of the above embodiment can be directly quoted, and no further description is given here.

The beauty device 1000 shown in Figures 8-10 uses a dual light source 20, 20', one of which can be an IPL light source, and the other can be a tungsten filament light source or a carbon fiber light source. Among them, the tungsten filament light source or the carbon fiber light source can obtain an infrared heating method, which has good spectral continuity, a wide spectrum (up to 300-2500nm) and a large near-infrared spectrum. The IPL light source in the dual light source is an intense pulsed light: it has a short luminous time, high peak light energy, and the photochemical reaction generated by the skin target receiving light energy is fast, which can instantly increase the temperature of the target; but the spectral continuity is poor and the near-infrared spectrum is small. The advantages of combining the two light sources are:

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

2) Complementary advantages: In the same band, the stable band of tungsten filament light source or carbon fiber light source is used to preheat the skin target to increase the basic temperature of the skin target and reduce the loss of IPL light energy. The instantaneous light energy of IPL strong pulse light acts on the heated skin target. This method can reduce the energy of IPL light source and increase the luminous speed of IPL light source while achieving the same treatment effect, and reduce the impact of high-energy IPL lamp tubes; achieving faster, gentler, safer and more effective treatment goals;

3) Enhanced beauty and other skin disease treatment range: Through the near-infrared spectrum of 900-2500nm band of tungsten filament light source or carbon fiber light source, the water molecules inside the skin resonate (all major medical journals/papers/magazines/clinical reports have confirmed the effect between the near-infrared band and water molecules), the underlying skin is heated up, and at the same time, refrigeration and temperature control methods are used to make the skin cool on the outside and hot on the inside, supplemented by the instantaneous photochemical thermal energy impact of the IPL light source, to achieve a more comfortable body feeling and better treatment effect.

When using the dual-light source therapeutic apparatus 1000, the dual light sources can be activated simultaneously, or one of the light sources can be used selectively.

In the above-mentioned first to fourth embodiments, the light outlet of the front end 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 component 80 is used as a light-transmitting panel, the cold surface 81 or the hot surface 83 of the semiconductor refrigeration component 80 can be made of the transparent crystal described in the above-mentioned embodiments, or other light-transmitting materials.

11-13, the beauty device 1000 of the fifth embodiment of the present application is a skin beauty mirror, including a housing 10 and a main control board 40 installed in the housing 10, and a light source unit and a power supply assembly electrically connected to the main control board 40. The light source unit includes 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, and the front housing 11 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 installed at 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.

The overall shape of the skin beauty mirror of this embodiment can be spherical, hemispherical, square or other shapes, and its front end surface forms a large light outlet or a large mirror surface. The front end of the shell 10 is adaptively mounted with the front shell 11. The shell 10 is spherical, hemispherical (including hemispherical or partially spherical), square or other shapes as a whole, and a cavity is formed inside. The light source part, power supply component and main control board are installed in the cavity of the shell.

The light-transmitting panel 12 can be sapphire, quartz, K9, glass or other suitable light-transmitting materials. In this embodiment, a transparent crystal 12 is used as the light-transmitting panel. The temperature of the light-transmitting panel is controlled by the temperature sensor assembly 50. The entire light-transmitting panel/transparent crystal covers the light outlet at the front end of the housing to form a large light-emitting surface or a large mirror surface. The light-emitting surface/mirror surface is approximately the size of the entire front end surface, which can achieve large-area whole-body skin beautification, and is faster and more efficient to use.

The light source unit includes a light source 20 and a reflector 21. The 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. The light source 20 includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade. A filter film is integrally attached to the transparent lampshade. The filter film can filter out light waves of a predetermined band, so that the light waves emitted by the light source 20 are light waves of a predetermined band after being filtered by the filter film on the lampshade, and are emitted from the light outlet to act on the skin surface for beauty or treatment. The light source 20 of this embodiment is a light source with a built-in filtering function, and the light source and the filter film are designed in an integrated manner. The reflector 21 has a large reflecting surface, and a cavity is formed inside, which is used to install the light source 20 and form a light outlet channel. The reflector 21 includes an arc-shaped (not limited to an arc-shaped) cover, the front end of which is open, and the front end opening of the reflector 12 is covered by a light-transmitting panel/transparent crystal 12. The light emitted by the light source 20 is a light wave of a predetermined band obtained after being filtered by a filter film on the surface of the light source, and is directly projected to the light-transmitting panel/transparent crystal 12 after being reflected by the inner surface of the reflector, and irradiates the skin surface after passing through the light-transmitting panel/transparent crystal 12 for skin beautification or treatment. The light source part of this embodiment adopts an integrated design of a light source and a filter film to obtain a light source 20 with a self-contained filtering function. There is no need to set 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 self-contained filtering function, and the ultraviolet light and the light/photothermal damage to the surrounding parts by intercepted photons have been eliminated in the emitted 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, improving the output of light energy, and there is no space for photons to leak sideways, which effectively improves the output of light energy.

The reflector 21 is made of heat-conducting material, and its edge is matched with the front edge of the front shell 11 and the front edge of the outer shell 10, and is clamped between the front shell and the outer shell. For example, the reflector is a (partial) spherical surface, and the edge is clamped by the front shell 11. The light source 20 is installed at the center of the inner top. A seat cover is formed at the center of the top of the reflector 21. The seat cover is provided with a through hole. The seat cover protrudes from the inside of the reflector 21 to the back. The light source 20 is inserted into the seat cover, and its electrode extends backward from the seat cover to be plugged with the main control board 40.

A heat sink 22 is provided on the back of the reflector 21. The shape of the heat sink 22 matches the shape of the reflector 21 and the shapes of the front shell 11 and the outer shell 10, and is arranged on the back of the reflector 21 for rapid heat transfer; or the heat sink 22 and the reflector 21 are an integral structure. The edge of the heat sink 22 is clamped on the front shell 11. The inner surface of the heat sink 22 matches the shape of the back of the reflector, and the examples are all spherical surfaces, which are arranged with the maximum contact area and fit each other. A through hole is provided in the center of the heat sink 22, and the seat cover provided at the top center of the reflector 21 passes through the through hole in the center of the heat sink 22 to install the heat sink 22. The heat sink 22 is a heat transfer structure, which can be made of a single heat conductive material such as aluminum/copper/graphene, or can be a heat pipe/heat absorbing plate VC/super heat conductive pipe or super heat conductive plate such as ALVC (aluminum superconducting tube or aluminum superconducting plate) and other components that use phase change (evaporation and condensation).

A heat shield 14 is also provided in the housing 10. The heat shield 14 is installed 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. The seat cover provided in the center of the top 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 installed in the seat cover, its electrode passes through the through hole of the heat shield and is electrically connected to the main control board 40. The shape of the heat shield 14 is adapted to the shape of the inner wall of the housing 10, and is tightly matched with the inner wall of the rear housing. It can be made of a heat-insulating material, and the cavity in the rear housing is separated from the front and back to separate the light source part from the main control board 40, so as to insulate and seal the main control board 40. For example, the heat shield 14 is disc-shaped.

The main control board 40 is installed in the cavity enclosed by the heat insulation board 14 and the housing 10. The main control board 40 is electrically connected to the key group, the light source 20, the temperature sensor assembly 50, the battery 30, and the power interface 41. The main control board 40 is provided with corresponding circuits and functional modules according to functional requirements. These circuits or functional modules can be provided by means of existing technology or corresponding electronic components can be purchased from the market, and functional software is provided accordingly. For example, the main control board 40 is provided with a power module, multiple control units, a radio frequency module, a temperature control module, etc.

The battery 30 may be a rechargeable battery, which is charged through the power supply interface 41. It may also be a disposable battery, which can be replaced, or no battery is provided, and the battery is directly connected to an external power source through the power supply interface 41 for direct power supply. The battery 30 is also installed in the cavity enclosed by the heat insulation board 14 and the housing 10.

The power supply interface 41 is provided on the housing 10 for connecting an external power source. The housing 10 is provided with a button component, and a power on/off button, a light source control button, a mode setting button, a radio frequency switch, etc. are provided as needed.

In this embodiment, the temperature sensor assembly 50 is a temperature sensor PCBA, which can be a flexible PCBA, but is not limited thereto, and 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 a light wave of the expected wavelength after filtering, and passes through the light-transmitting panel/transparent crystal 12 to irradiate the skin, the temperature of the light-transmitting panel/transparent crystal is detected by the temperature sensor assembly 30, and the power and switch of the light source 20 are controlled by the main control board 40 to control the temperature range, so as to avoid burns to the skin due to long-term use.

In the skin beautifying instrument 1000 of the present embodiment, the light emitted by the light source 20 is a light wave of the expected wavelength obtained after filtering by the self-contained filter film, and is irradiated on the skin at a constant temperature through the light-transmitting panel/transparent crystal 12. The light filter film on the surface of the light source can filter out the undesired wavelengths to obtain the light waves of the predetermined wavelengths, and the light waves act on the skin in a targeted manner to achieve the purpose of beauty and skin care. For example, the light filter film on the surface of the light source is in the 500-600nm wavelength band, and the light emitted by the light source 20 is a light wave of the expected wavelength obtained after filtering by the self-contained filter film, and then passes through the light-transmitting panel/transparent crystal 12 to act on the epidermis of the human body; and the light filter film on the surface of the light source is in the 900-1800nm wavelength band, and the light waves emitted from the light-transmitting panel act on the basal layer and melanocytes of the human body.

14-16, the beauty device 1000 of the sixth embodiment of the present application is a skin beauty mirror, which is different from the fifth embodiment in that the light-transmitting panel is replaced by a semiconductor cooling element 80 with a transparent crystal end face by a transparent crystal 12. The semiconductor cooling element, also known as a thermoelectric cooling element (TEC) or a heat pump or a Peltier cooling element (Peltier cooler); includes a semiconductor particle layer 82 in the middle and a hot surface 81 and a cold surface 83 at both ends, and also includes a pair of positive and negative electrodes to electrically connect the circuit of the semiconductor cooling element to a control unit arranged on the main control board 40 or an independently arranged control board, and the independently arranged control board is electrically connected to the main control board 40. The hot surface 83 and/or the cold surface 81 are set as transparent crystals. For example, the cold surface 81 is a whole transparent crystal that can contact the skin, and the hot surface 83 and the semiconductor particle layer 12 are set in a ring shape. The hot end circuit (such as a conductor) provided on the edge annular belt of the transparent crystal cold surface 81 is welded and electrically connected to the cold end of the semiconductor particle layer; the hot surface 83 is a heat-conducting material substrate provided with a hot end circuit (such as a conductor), which is welded and electrically connected to the hot end of the semiconductor particle layer, thereby connecting the internal circuit of the semiconductor refrigeration component, and the positive and negative electrodes are electrically connected to the control unit. The transparent crystal cold surface corresponding to the middle area of the annular hot surface and the semiconductor particle layer forms a light-emitting surface, which can be configured as a large-area light-transmitting panel/mirror that is similar to the entire front end of the skin beauty instrument.

The hot surface 83 of the semiconductor refrigeration element 80 is connected to a heat sink 16 for dissipating heat from the hot surface 83 of the semiconductor refrigeration element. The heat sink 16 is a heat transfer structure, which can be made of a single heat-conducting material such as aluminum/copper/graphene, or can be a heat pipe/temperature averaging plate VC/super heat-conducting pipe or super heat-conducting plate such as ALVC (aluminum superconducting tube or aluminum superconducting plate) and other components that utilize phase change (evaporation and condensation). In this embodiment, the heat sink 16 is annular, and the annular end surface and the annular hot surface 83 of the semiconductor refrigeration element are quickly heat-transferred, and can be mutually fitted; the annular heat sink 16 is tightly sleeved on the front end outer wall of the reflector, and they are in contact with each other for heat conduction. The shape of the semiconductor refrigeration element 80 is adapted to the opening of the reflector and is sealed on the opening of the reflector 21, and the light source 20 with a self-filtering function is sealed in the reflector 21. The sixth embodiment has the same structure and configuration as the fifth embodiment, and refers to the aforementioned embodiment.

Referring to Figure 18, the skin beauty instrument 1000 of the seventh embodiment of the present application is a skin beauty mirror, in which the light source 20 with built-in filtering function is different from the fifth and sixth embodiments in that the skin beauty mirror of this embodiment is provided with a radio frequency component or an EMS component. The radio frequency component or the EMS component includes a radio frequency electrode assembly or an 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 surface of the skin beauty mirror. The radio frequency/EMS electrode assembly 90 is electrically connected to the main body of the skin beauty 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 beauty instrument 1000. The main control board 40 is integrated with functional modules such as a control unit, a DC power supply module, a light source control module, and a radio frequency drive module. The RF/EMS electrode assembly 90 includes an electrode fixing frame 81 and one or more RF/EMS electrodes 92 mounted by the electrode fixing frame 91. The ends of each pair of RF/EMS electrodes 92 are provided with positive and negative electrodes 93, and the positive and negative electrodes 93 are electrically connected to the main control board 40 through wires 95. For example, a plurality of magnets 94 may also be installed on the fixing frame 91, and a plurality of magnets 94 are correspondingly installed in the front shell 11 of the skin beautifying instrument, so that magnetic adsorption is formed between the RF/EMS assembly 80 and the main body 100 of the skin beautifying instrument. A mounting hole 910 is provided on the fixing frame 91, and the RF/EMS electrode 92 is adapted to the mounting hole 910 and embedded in the mounting hole 910. In this embodiment, the photon skin beautification and RF/EMS functions can be activated by a key group, and RF-assisted treatment can be obtained at the same time during photon skin beautification, and different light bands + RF treatment can be realized. The working principle of RF/EMS is the same as that of the above-mentioned embodiment. The structure and configuration of the sixth embodiment that are the same as those of the fifth and sixth embodiments refer to the above-mentioned embodiment.

The skin beautifying device of the fifth to seventh embodiments of the present application has a light-transmitting panel similar to the size of the front face of the skin beautifying device and a large mirror surface, which can achieve large-area whole-body skin beautification and is faster and more efficient to use. When using the device, the light-transmitting panel/transparent crystal outer surface is placed against the skin.

19-25, the beauty device of the eighth embodiment of the present application is a beauty mask, which includes a housing 10, a main control board 40 disposed in the housing 10, and a light source unit. The light source unit includes a light source 20 and a reflector 21. A light-transmitting panel 12 is disposed at the front end of the housing 10 and forms a light outlet. The light-transmitting panel 12 is disposed in front of the front of the housing 10 and covers the light source in the space between the housing 10 and the reflector 21. The light source 20 is electrically connected to the main control board 40.

The light source 20 of this embodiment has a built-in light filtering function, and the light source and the filter film are designed in an integrated manner. Specifically, the light source includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element (such as a filament) in the lampshade. The transparent lampshade is integrally attached with a filter film, which can filter out light waves of a predetermined band. The light emitted by the light source 20 is a light wave of the expected band obtained after being filtered by the built-in filter film, and passes through the light outlet to illuminate the skin surface. For example, the light emitted by the light source is a light wave of 500-1800nm or 900-1800nm obtained after being filtered by the filter film, which acts on the skin for beauty or treatment.

The filter film can be formed on the surface of the transparent lampshade through an optical coating process. Since the lampshade surrounds the light source, all the light emitted by the light-emitting element in the transparent lampshade is filtered by the filter film before being emitted. The light emitted by the light source is a light wave with the expected wavelength after filtering. The optical coating process can be used to prepare the filter, which is to perform optical coating on a transparent substrate. This technology is a prior art. The present application uses a transparent lampshade as a carrier transparent substrate for the coating process, and adopts the same coating process as the preparation of the filter to coat the surface of the transparent lampshade to form an integrated structure of the filter film and the light source, thereby obtaining a light source with a self-filtering function.

Examples of optical coating processes include evaporative deposition, ion beam sputtering (IBS), plasma sputtering, atomic layer deposition (ALD), etc. In some embodiments, a coating layer is formed on a transparent lampshade according to an optical coating process; wherein a single-band filter film that passes a single band is formed by single-band coating, such as a single-band filter film that passes 500-1800nm, 900-1800nm, and 500-600nm; or, a single-band filter film that passes two or more bands at the same time is obtained by multi-band coating, such as a dual-band filter film that passes 500-600nm+900-1800nm obtained by dual-band coating; or, a multi-band filter film that passes multiple bands in different bands in different partitions is obtained by partition coating on the transparent lampshade, for example, the filter film obtained by partition coating has zone A: 500-600nm; zone B: 900-1800nm. The filter film with partition coating can switch different partitions of the filter film by rotating the light source to obtain light of different wavelengths. The rotating light source can be driven to rotate by installing rotating structures such as gears/racks/motor drive rotation at both ends of the light source.

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

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

The light emitted by the light source 20 is filtered by the filter film coated on the transparent lampshade to obtain the light of the expected wavelength band, which is directly reflected by the reflector 21 and then passes through the light-transmitting panel 12 to irradiate the skin for treatment/beautification. The emitting direction is the front direction of the housing 10, and the area a in the figure is the light emitting area. The front direction is the direction toward the face of the user when wearing the beauty mask, and the light of the light source 20 is emitted from the front direction and irradiates the face of the user wearing the beauty mask.

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

The light source with built-in filtering function of the present application 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 suitable for skin treatment or beauty. The corresponding wavelength is selected according to the purpose and effect of the treatment or beauty. As for which wavelength should be selected to correspond to the symptoms and treatment/beauty plan, it is a matter for the treatment or beauty user or physician to consider, and it is also a knowledge field of the beauty industry. It does not affect the implementation and technical effect of the technical solution of the present application. The present application provides a device that can be used for the treatment/beauty. After determining the wavelength required for the treatment/beauty plan, the beauty mask of the present application and its corresponding light source with built-in filtering function are used.

The beauty mask of this application is a non-contact beauty method. It uses a large area of full-face light to cover all areas of the face at the same time, including the nose, lips and other blind spots. The whole-face irradiation will ensure the consistency of facial skin treatment to the greatest extent, greatly improve the overall whitening and rejuvenation of the facial skin, and stimulate the beneficial effects of collagen regeneration. At the same time, compared with the photon skin rejuvenation device on the market, each flash can only act on a small area of skin. According to the size of the facial area, it takes dozens or hundreds of times to cover the entire face. The application only uses the whole face to irradiate once to cover the entire face, which greatly shortens the use time. Each flash of this application (0.2-3 seconds) is equivalent to using the photon skin rejuvenation device on the market once (about 3-5 minutes). If the application uses 30 flashes each time, each use is equivalent to dozens of times the effect of the conventional photon skin rejuvenation device. This application uses the method of wearing a mask for treatment/beauty. Turning on the light source can obtain the required band of light waves, and directly irradiate the face to implement the treatment/beauty plan. The operation is very convenient.

For example, the light source 20 of the light source part 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 the light sources 20. In this embodiment, each light source 20 corresponds to a reflector. The reflector 21 can be three reflectors connected as 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 can be understood that the reflector 21 can also be an integral structure, forming three arc shapes corresponding to the rear of the three lamp tubes.

The beauty mask also includes a heat sink 22, which is arranged behind the reflector 21 and matches the shape of the reflector, or is an integral structure with the reflector 21. The heat sink 22 is a heat sink, or a combination of one or more of a heat pipe, a temperature plate, a super heat pipe, a super heat plate, or a heat conductive substrate made of a single heat conductive material (such as aluminum or copper). The heat dissipation of the light source 20 can also be replaced by a fan blowing/sucking method. The beauty mask also includes a mask rear shell 15, which is installed in conjunction with the outer shell 10 to form a cavity that can accommodate the light source 20, the reflector 21, and the heat sink 22. The mask rear shell 15 is arranged at the rear of the beauty mask, and the rear is the side opposite to the front direction of the beauty mask, which is the side facing away from the face of the user when the beauty mask is worn. The mask rear shell 15 is provided with a ventilation hole 101 connected to the cavity to facilitate heat dissipation and cooling.

The beauty mask further comprises a head stopper 17, which is fixedly installed or detachably arranged on the front side of the shell 10, so as to facilitate the user to wear and position the head and maintain a certain safety distance.

The beauty mask further comprises a retractable belt 18. When the beauty mask is worn, the retractable belt 18 is wrapped around the user's head to help fix the beauty mask. The retractable belt 18 has a retractable adjustment structure, or the retractable belt 18 is elastic and can be applied to different users.

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

As shown in FIG. 23 , the beauty mask is further provided with a main control board 40 in the housing 10, and the light source 20 is connected to the main control board 40. In this embodiment, the main control board is provided in the housing 10. In other embodiments, the main control board may be provided outside the beauty mask, and is connected to power through a socket when in use. The power supply assembly includes a power supply interface and/or a battery 30. For example, the housing 10 (the front housing 11 or the rear housing 15) is provided with a power supply 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 supply to provide power. The battery 30 may be provided in a cavity between the housing and the rear housing, or may be provided in an external power supply seat 31, and may be connected to the power supply interface through a power cord or electrically connected in a plug-in manner. In other embodiments, a battery may not be provided, and the beauty mask may be powered directly through an external power supply connected to the power supply interface. For example, referring to FIGS. 24-25 , a battery 30 and a power supply circuit board 34 are provided in the power supply seat 31, and the two are electrically connected. The power supply interface of the beauty mask and the power circuit board 34 can be connected via a power line.

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, and then passes through the transparent panel 12 to illuminate the skin surface for beauty or treatment.

26-27, the beauty device 1000 of the ninth embodiment of the present application is a beauty mirror, which includes a housing 10, a main control board 40 disposed in the housing 10, and a light source and a power supply component electrically connected to the main control board 40. A large window is formed at the front end of the housing 10 and connected to a front shell 11 of a frame-type structure, a cavity is formed inside, and a large window is formed at the front end of the beauty mirror, and a light-transmitting mask 12 is installed in the large window to form a large light outlet or a large mirror surface.

The light source unit includes a light source 20 and a reflector 21 on which the light source 20 is mounted. A large opening is formed at the front end of the reflector and is covered by the light-transmitting panel 12, thereby covering the light source 20 in the reflector 20. The light source 20 has a filtering function. The light source 20 is filtered by the filter film on the surface of the light source, and then reflected by the reflector 21 and passes through the light-transmitting panel 12 to illuminate the skin.

The light source 20 of this embodiment has a built-in light filtering function, and the light source and the filter film are designed in an integrated manner. Specifically, the light source includes a transparent lampshade (such as a light bulb or a lamp tube) and a light-emitting element in the lampshade, and a filter film is integrally attached to the transparent lampshade, and the filter film can filter out light of non-ideal wavelengths. The light emitted by the light source 20 is a light wave of the expected wavelength obtained after being filtered by the built-in filter film, and is emitted from the light outlet to act on the skin surface. For example, the light emitted by the light source is a light wave of 500-1800nm or 900-1800nm obtained after being filtered by the filter film, and acts on the skin for beauty or treatment.

The filter film can be formed on the surface of the transparent lampshade through an optical coating process. Since the lampshade surrounds the light source, all the light emitted by the light-emitting element in the transparent lampshade is filtered by the filter film before being emitted. The emitted light of the light source is a light wave with the expected wavelength after filtering. The optical coating process can be used to prepare the filter, which is to perform optical coating on a transparent substrate. This technology is a prior art. The present application uses a transparent lampshade as a carrier transparent substrate for the coating process, and adopts the same coating process as the preparation of the filter to coat the surface of the transparent lampshade to form an integrated structure of the filter film and the light source, thereby obtaining a light source with a self-filtering function.

Examples of optical coating processes include evaporative deposition, ion beam sputtering (IBS), plasma sputtering, atomic layer deposition (ALD), etc. In some embodiments, a coating layer is formed on a transparent lampshade according to an optical coating process; wherein a single-band filter film that passes a single band is formed by single-band coating, such as a single-band filter film that passes 500-1800nm, 900-1800nm, and 500-600nm; or, a single-band filter film that passes two or more bands at the same time is obtained by multi-band coating, such as a dual-band filter film that passes 500-600nm+900-1800nm obtained by dual-band coating; or, a multi-band filter film that passes multiple bands in different bands in different partitions is obtained by partition coating on the transparent lampshade, for example, the filter film obtained by partition coating has zone A: 500-600nm; zone B: 900-1800nm. The filter film with partition coating can switch different partitions of the filter film by rotating the light source to obtain light of different wavelengths. The rotating light source can be driven to rotate by installing rotating structures such as gears/racks/motor drive rotation at both ends of the light source.

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

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

The light-transmitting panel 12 of this embodiment is a convex lens, which is used for light wave transmission, so that the face receives light more evenly. By using the principle of convex lenses, the divergent light is refracted to the light-emitting area after passing through the convex lenses and emits light evenly. The light-transmitting panel/convex lens 12 of this embodiment uses a large area of full-surface light emission, which can cover all areas of the face at the same time, including blind spots such as the nose and lips. Full-surface irradiation will ensure the consistency of facial skin treatment to the greatest extent, greatly improving the overall whitening and rejuvenation effects of facial skin. Using full-surface irradiation can cover the facial skin, greatly shortening the use time.

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

A heat sink 22 is also installed in the housing 10. The heat sink 22 is arranged behind the reflector 21 and matches the shape of the reflector, or is an integral structure with the reflector 21. The heat sink 22 is a heat sink, or a combination of one or more of a heat pipe, a temperature equalizer, a super heat pipe, a super heat plate, or a heat conductive substrate made of a single heat conductive material (such as aluminum or copper). The heat generated by the light source is quickly transferred to the heat sink 22 by the reflector 21. The heat dissipation of the light source 20 can also be replaced by a fan blowing/sucking method. The housing 10 is provided with a ventilation hole 101 connected to the internal cavity, which is convenient for heat dissipation of the heat sink 22 and the reflector 21.

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

The power supply assembly includes a power supply interface and/or a battery 30. For example, the housing 10 is provided with a power supply 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 supply to provide power. The battery 30 can be arranged in the housing 10, or in an external power supply socket 31, and connected to the power supply interface through a power cord or electrically connected in a plug-in manner. In other embodiments, a battery may not be provided, and the beauty mirror may be powered directly through an external power supply connected to the power supply interface. For example, a battery 30 and a power supply circuit board 34 are provided in the power supply socket 31, and the two are electrically connected. The power supply interface of the beauty mirror and the power supply circuit board 34 can be connected through a power cord.

For example, a connecting frame 61 may be provided between the power socket 31 and the housing 10. A ventilation channel communicating with the inner cavity of the housing 10 is provided in the connecting frame 61, and a fan 60 is also provided in the connecting frame. The housing 10 of the beauty mirror is provided with a ventilation hole 101. The reflective element 21 and the heat sink 22 of the light source are cooled by air through the blowing/sucking method of the fan 60.

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

When using the beauty mirror, the mirror is pointed toward the user's face, and the light source is turned on by operating the button group. The light emitted by the light source 20 is filtered by the filter film on the transparent lampshade to obtain the light wave of the expected band. The emitted light wave passes through the light-transmitting panel/convex lens 12 and then irradiates the skin surface for beauty or treatment. The beauty mirror of this embodiment uses a large area of full-surface light output to cover all areas of the face at the same time, including the nose, lips and other blind spots. Full-surface irradiation will ensure the consistency of facial skin treatment to the greatest extent, greatly improving the overall whitening and rejuvenation effect of facial skin.

The beauty devices of the above-mentioned various embodiments use a light source with a built-in filtering function, which has a simpler structure, reduces filters, saves filter materials and assembly, maintenance and other costs; the light emitted by the light source is filtered before being emitted, and the filtering eliminates ultraviolet rays and light/photothermal 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 side leakage of photons, which effectively improves the output of light energy.
