Description

Technical Field

[0001] The present application relates to the field of beauty technology, and in particular to a natural light beauty shield. Background Art

[0002] When people are doing outdoor activities, they will be exposed to natural light, which contains harmful light waves. Especially when the sun is strong, harmful light waves such as ultraviolet rays are very harmful to human skin and can cause skin diseases such as dark spots and freckles. Ladies who love beauty are more afraid of being tanned and unsightly. At present, people often use special sunscreens and other chemicals to filter out harmful light waves in natural light, or use tools such as sun hats to block them. However, the effects of existing tools such as sunscreens and sun hats are often limited. The use of chemicals such as sunscreens is another burden on the skin, which easily causes skin pores to be blocked, and the greasy and heavy feeling when using them is often not very comfortable. The use of tools such as sun hats cannot completely filter out harmful light waves. With environmental changes, more and more people are accustomed to wearing masks and face masks when traveling, which are used for shading, dust prevention, and to a certain extent to avoid damage to the skin caused by ultraviolet rays. However, the use of masks or face masks, like tools such as sun hats, cannot completely filter out harmful light waves. Whether it is sunscreen, sun hat or mask, they all have a single function and the effect of filtering harmful light is very limited. In addition, there are a lot of visible light and near-infrared light in natural light, which are beneficial to skin health.

[0003] With the development of society and the improvement of people's living standards, the beauty industry has also developed rapidly. Traditional beauty methods mainly rely on chemical drugs or artificial electronic devices, which often have certain side effects and risks, and are also very troublesome to use. Chemical drugs have side effects and harm to the skin to a certain extent, and the products on the market are of varying quality. Consumers need to spend time and effort to purchase them, and they may not be satisfied. Artificial electronic devices such as LED irradiation beauty, laser beauty and other electronic products must be powered when used, and cannot be worn outside, which is very time-consuming and troublesome.

[0004] In summary, there is currently no beauty product on the market that is easy to use, has good beauty effects, has few side effects, can be used in a variety of occasions, can utilize natural light, and has both sun protection and skin beautification functions. Summary of the invention

[0005] The purpose of the present application is to provide a natural light beauty shield which is easy to use, has good beauty effects, and is safe and reliable.

[0006] In order to achieve the purpose of this application, the following technical solutions are provided: The present application provides a natural light beauty shield, which includes a laminated substrate layer and a filter layer, wherein the substrate layer is made of a light-transmitting material, and the filter layer can cut off light waves of a specific wavelength incident from a first direction. The first direction is the direction in which light from the outside world enters the natural light beauty shield when the natural light beauty shield is worn on a user, such as on the face or neck.

[0007] In some implementations, the substrate layer is made of a transparent material, or a microporous light-transmitting material, such as cloth or gauze.

[0008] In some implementations, the light waves in the specific wavelength band include at least one wavelength interval.

[0009] In some embodiments, the light waves in the specific wavelength band include at least light waves in a first wavelength band, and the light waves in the first wavelength band are selected from an ultraviolet light band.

[0010] In some embodiments, the filter layer can cut off incident light waves in a first wavelength band, transmit incident light waves in a second wavelength band, and reflect light waves in a third wavelength band.

[0011] The filter layer is a specific filter film layer, which can cut off light waves of a specific wavelength band and not allow them to enter, but allow light waves of other wavelengths to enter. The light waves of the specific wavelength band may include at least one wavelength interval, with ultraviolet light cutoff as the preferred wavelength band, or it may be a dual-interval or multi-interval wavelength band. For example, the specific wavelength band light wave selects the 280~400nm wavelength band, or the 450~550nm wavelength band, or the 600~700nm wavelength band; for another example, the specific wavelength band light wave selects the wavelength band including the two intervals of 450~550nm and 600~700nm; or the specific wavelength band light wave selects the wavelength band including the two intervals of 500~615 and 900~1800nm, for example, the light wave of the 900-1800nm ​​wavelength band interval is cut off, that is, the visible light is blocked so that the visible light cannot penetrate, while the near infrared light can pass through; or the intervals of a finer range are selected, etc., so that the light of the wavelength band that has a beauty or therapeutic effect on the skin is incident on the user's skin through the natural light beauty shield. In a more specific embodiment, the cut-off wavelength of the filter layer is 280nm-400nm, the light transmission wavelength is 400nm-700nm, and the reflection wavelength is 700nm-2500nm. In some embodiments, the filter layer is a unidirectional light transmission layer.

[0012] In some embodiments, the filter layer is a filter film disposed on the substrate layer, and the filter film can be disposed on the outer surface or the inner surface of the substrate layer by coating means.

[0013] In other embodiments, the filter layer is an optical coating film, and the filter layer and the substrate layer are sequentially stacked along the first direction, or sequentially stacked along a direction opposite to the first direction. The optical coating film can be a soft film or a hard film.

[0014] In some embodiments, the natural light beauty shield further comprises a cover layer, the cover layer is made of a light-transmitting material, and the cover layer and the substrate layer are stacked in sequence along the first direction. In a specific embodiment, the cover layer is made of a transparent material or a microporous light-transmitting material (such as cloth or gauze, etc.).

[0015] In some embodiments, the filter layer is disposed between the cover layer and the substrate layer, and the cover layer, the filter layer, and the substrate layer are stacked in sequence along the first direction. Specifically, the filter layer can be disposed on the outer surface of the substrate layer or on the inner surface of the cover layer by coating means, and the filter layer can also be an optical coating film sandwiched between the cover layer and the substrate layer. When the filter layer is disposed between the substrate layer and the cover layer, the substrate layer plays a role in improving the comfort of contact with the skin and separating the cover layer and the filter layer from the skin, and can provide support to strengthen the stability of the filter layer. The cover layer can provide support and protection for the substrate layer and the filter layer, and a pattern or color can be set on the cover layer for beautification, and the pattern and color do not affect the originally set optical properties of light transmission, light filtering and light reflection.

[0016] In some embodiments, the filter layer is disposed on the outer surface of the cover layer, and the filter layer, the cover layer, and the substrate layer are sequentially stacked along the first direction. Specifically, the filter layer can be disposed on the outer surface of the cover layer by coating means, or the filter layer is disposed outside the cover layer by using an optical coating film. In this case, the substrate layer plays a role in improving the comfort of contact with the skin and separating the cover layer and the filter layer from the skin; or the filter layer is disposed on the inner surface of the substrate layer, and the cover layer, the substrate layer, and the filter layer are sequentially stacked along the first direction. Specifically, the filter layer can be disposed on the inner surface of the substrate layer by coating means, or is disposed inside the substrate layer by using an optical coating film. In this case, the substrate layer can provide support to strengthen the stability of the filter layer. In a specific embodiment, the filter layer is usually disposed between the cover layer and the substrate layer to improve the comfort of the substrate layer in contact with the skin and protect the filter layer.

[0017] In some embodiments, the filter layer may be a whole-layer integrated structure, or a combination of multiple units distributed in different areas, and the cutoff light wave band of each unit may be the same or different.

[0018] In some embodiments, the filter layer includes a superposition of one or more specific filter film layers that cut off light waves in a specific wavelength range to achieve cutting off the incidence of light waves in at least one wavelength range, or different cutoff bands are set in each area in a partitioned distribution manner.

[0019] In some embodiments, the natural light beauty shield is in the shape of a face mask or a mouth mask for use on the face, or a neck shield for use on the neck, or an integrated face and neck shield, or is used as a sun hat baffle.

[0020] Compared with the prior art, this application has the following advantages: The natural light beauty shield of the present application filters light in a targeted manner through the filter layer, cuts off the incident light of harmful wavelengths, and allows the light of wavelengths that have cosmetic or therapeutic effects on the skin to be incident on the user's skin through the natural light beauty shield, and uses the light waves in natural light to whiten the skin, remove redness, rejuvenate the skin, stimulate collagen regeneration, etc. The light waves of sunlight are a full-spectrum light source, which contains light waves of various wavelengths that are useful to the skin, such as infrared rays above 900nm and visible light of 500-700nm, which can remove dark spots and acne on the skin, stimulate collagen regeneration, remove red blood streaks, and activate blood circulation. Therefore, the natural light beauty shield of the present application can be used as an outdoor beauty tool, which uses natural sunlight energy for beauty during people's travel. It is a new energy-saving beauty method, and it also saves the user's time for beauty alone. It is very convenient to wear and operate, and reduces interference with people's normal travel and activities. It not only solves the sun protection problem, but also takes into account the beauty effect, and can achieve dustproof and beautiful functions at the same time, and has the functions of masks, masks, sun hats and beauty.

[0026] See also Figure 1 and 2 In the first embodiment, the natural light beauty shield of the present application includes a laminated substrate layer 130, a filter layer 120, and a cover layer 110. The substrate layer 130 and the cover layer 110 are made of light-transmitting materials, and can be transparent materials or microporous light-transmitting materials. The microporous light-transmitting materials are specifically cloth or gauze. The filter layer 120 can cut off light waves of a specific wavelength incident from a first direction. The first direction is the direction in which light from the outside world enters the natural light beauty shield when the natural light beauty shield is worn on the user, such as on the face or neck.

[0027] The filter layer 120 can cut off light waves of a specific wavelength band and not allow them to be incident, while allowing light waves of other wavelengths to be incident. The light waves of the specific wavelength band include at least one wavelength interval. Specifically, the light waves of the specific wavelength band at least include light waves of the first wavelength band, and the light waves of the first wavelength band are preferably selected from the ultraviolet light band. In another embodiment, the filter layer 120 can cut off the incident light waves of the first wavelength band, and can also transmit the incident light waves of the second wavelength band and reflect the light waves of the third wavelength band.

In a more specific embodiment, the cutoff wavelength of the filter layer 120 is 280nm~400nm, the light transmission wavelength is 400nm-700nm, and the reflection wavelength is 700nm-2500nm. The specific correspondence between the selection of the wavelength range and the skin beauty treatment function belongs to the category of cosmetic medicine, and can be selected through the public cosmetic medicine knowledge to achieve the corresponding cosmetic medical function, such as cosmetic medicine journals or papers, other existing public achievements in cosmetic medicine, etc., to know which specific wavelengths can be cut off to prevent light damage to the skin, and which wavelengths can be passed to allow light to have a cosmetic effect on the skin.

[0029] In the first embodiment, the filter layer 120 is an optical coating film, the cover layer 110, the filter layer 120 and the substrate layer 130 are stacked in sequence along the first direction, and the filter layer 120 is arranged between the cover layer 110 and the substrate layer 130. By being fixed between the cover layer 110 and the substrate layer 130, it will not be easily displaced or fall off, thereby ensuring the stability and durability of the filtering effect. The optical coating film can be a soft film or a hard film. In other embodiments, the filter layer 120 is a filter film arranged on the substrate layer 130, and the filter film can be arranged on the outer surface or inner surface of the substrate layer 130 by coating means.

[0030] The cover layer 110 plays the role of shaping, protection, dust prevention, and aesthetics. It can be a transparent material or a microporous light-transmitting material (such as cloth or gauze, etc.), thereby improving the light transmittance and comfort of the mask. The material selection takes into account multiple factors such as comfort, light transmittance, and durability, ensuring comfortable wearing and a good service life. The materials of the substrate layer 130 and the cover layer 110 can be the same or different. In a specific embodiment, the substrate layer 130 and the cover layer 110 are made of polycarbonate (PC), which has good light transmittance, weather resistance, and comfort.

[0031] Please refer to Figures 1 to 3The appearance of the natural light beauty shield is an integrated shield for the face and neck.

[0032] The filter layer 120 may be a whole-layer integrated structure, or a combination of multiple units distributed in different zones, and the cutoff wavelength band of each unit may be the same or different. The filter layer 120 includes a superposition of one or more specific filter film layers that cut off wavelengths in a specific wavelength range to achieve the cutoff of the incident wavelengths in at least one wavelength range, or a different cutoff wavelength band may be set in each area in a zoned distribution manner. For example, different filter wavelength bands may be selected in different zones for different skin care treatment needs at different locations on the face. When the filter layer 120 is a filter film disposed on the substrate layer 130, it can be realized by partition coating, for example, the forehead and cheek areas of the face are coated with filter films with different cutoff bands respectively; when the filter layer 120 is an optical coating film, a partition film is used, which can be sandwiched between the cover layer 110 and the substrate layer 130 by lamination, or can be disposed between the cover layer 110 and the substrate layer 130 by bonding, or bonded to the outer surface or inner surface of the cover layer 110, or bonded to the outer surface or inner surface of the substrate layer 130.

The microporous light-transmitting materials are specifically cloth or gauze. The filter layer 220 can cut off light waves of a specific wavelength incident from a first direction. The first direction is the direction in which light from the outside world enters the natural light beauty shield when the natural light beauty shield is worn on the user, such as on the face or neck.

[0034] The filter layer 220 can cut off light waves of a specific wavelength band and not allow them to be incident, while allowing light waves of other wavelengths to be incident. The light waves of the specific wavelength band include at least one wavelength interval. Specifically, the light waves of the specific wavelength band at least include light waves of the first wavelength band, and the light waves of the first wavelength band are preferably selected from the ultraviolet light band. In another embodiment, the filter layer 220 can cut off the incident light waves of the first wavelength band, and can also transmit the incident light waves of the second wavelength band and reflect the light waves of the third wavelength band. The filter layer 220 can be made into a unidirectional light-transmitting layer, that is, it is light-transmitting along the first direction, but not light-transmitting along the opposite direction.

[0035] The filter layer 220 is an optical coating film. The cover layer 210, the filter layer 220 and the substrate layer 230 are stacked in sequence along the first direction. The filter layer 220 is arranged between the cover layer 210 and the substrate layer 230. By being fixed between the cover layer 210 and the substrate layer 230, it will not be easily displaced or fall off, thereby ensuring the stability and durability of the filtering effect.

For easy wearing, the natural light beauty shield may be provided with an auxiliary structure for wearing, such as an ear hanging rope similar to that for wearing a mask, a fixing piece for fixing to a sun hat, a head rope for fixing the integrated face and neck shield to the face and neck, etc.

[0040] The natural light beauty shield of the present application filters light in a targeted manner through the filter layer 120, cuts off the incident light of harmful wavelengths, and allows the light of wavelengths that have cosmetic or therapeutic effects on the skin to be incident on the user's skin through the natural light beauty shield, and uses the light waves in natural light to whiten the skin, remove redness, rejuvenate the skin, stimulate collagen regeneration, etc. The light waves of sunlight are a full-spectrum light source, which contains light waves of various wavelengths that are useful to the skin, such as infrared rays above 900nm, and visible light of 500-700nm, which can remove dark spots and acne on the skin, stimulate collagen regeneration, remove red blood streaks, and activate blood circulation. Therefore, the natural light beauty shield of the present application can be used as an outdoor beauty tool, which uses natural sunlight energy for beauty during people's travel. It is a new energy-saving beauty method, and it also saves the user's time for beauty alone. It is very convenient to wear and operate, and reduces interference with people's normal travel and activities. It not only solves the sun protection problem, but also takes into account the beauty effect, and can achieve dustproof and beautiful functions at the same time, and has the functions of masks, masks, sun hats and beauty.

[0041] When in use, the natural light beauty shield can be worn on the face, so that the natural light passes through the filter on the natural light beauty shield and irradiates the skin. Specifically, when worn, the substrate layer 130 contacts the skin, and the natural light enters through the cover layer 110 and the filter layer 120. After filtering the light of a specific wavelength, it irradiates the skin, and the light waves in the natural light are used to whiten the skin, remove redness, rejuvenate the skin, stimulate collagen regeneration, etc. By filtering light, the light waves in natural light are used to whiten the skin, which is a non-invasive skin beauty method. This method uses the filter layer 120 to filter harmful light waves in natural light, such as ultraviolet rays and blue light, while allowing beneficial light waves, such as red light and near infrared rays. These beneficial light waves can promote the metabolism of skin cells, increase blood circulation in the skin, and improve the texture of the skin, thereby achieving a whitening effect. Specifically, the duration of the process can be adjusted according to the individual's skin condition and needs, generally 10-30 minutes, or longer, to achieve the purpose of using natural light for beauty, while improving the light transmittance and comfort of the mask, and reducing interference with people's normal travel and activities. This method mainly uses light waves in natural light to whiten the skin, remove redness, rejuvenate the skin, stimulate collagen regeneration, etc. This method is not only safe, but also saves time and money. The method of using natural light for beauty has solved the safety and side effect problems of traditional beauty methods to a certain extent.

[0042] Compared with the prior art, the natural light beauty shield of the present application improves the effect of natural light beauty. The effects of existing tools such as sunscreens and sun hats are often limited and cannot completely filter out harmful light waves, thereby improving safety. The technical solution of the present application uses optical diaphragms to filter out harmful light waves in natural light, such as ultraviolet light, and only allows beneficial light waves to irradiate the skin, such as allowing visible light and near-infrared light to pass through, thereby improving the effect of natural light beauty. This can not only avoid the damage of harmful light waves to the skin, but also use beneficial light waves to promote skin health. Compared with existing tools such as sunscreens and sun hats, the present invention is safer. The cover layer and the substrate layer are light-transmitting materials, which can be transparent materials or microporous light-transmitting materials, thereby improving the light transmittance and comfort of the shield. On the other hand, the interference with people's normal travel and activities is reduced. The existing methods of using natural light for beauty, such as using special sunscreens or sun hats, may affect people's normal travel and activities. In the technical solution of the present application, optical films are fixed on the surface and inner layers of masks / face shields. People can use natural sunlight energy for beauty during travel, which also saves users' time for beauty treatments alone, thereby reducing interference with people's normal travel and activities.

[0043] The above description is only a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any equivalent transformation based on the technical solution of the present application belongs to the protection scope of the present application.
