Description

Multifunctional head cover

Technical Field

The invention relates to a multifunctional hood. And more particularly, to a multifunctional head cover having functions of growing hair and removing wrinkles and tightening skin at the same time.

Background

Technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and Photo Biological Modulation (PBM) appear in the middle and later stages of the 20 th century, and both technologies are applied to the medical field by taking illumination as a means for treating diseases (Michael r. There are several studies that red to near infrared illumination helps to promote regeneration of tissues such as collagen and skin cells, and can be applied in the fields of anti-wrinkle beauty, promotion of wound healing, spot removal, scar elimination, stimulation of hair growth, etc. (Chan Hee Nam et al, dermotologic Surgery, 2017, daniel barolet, semin Cutan Med surg, 27-227, 2008, yongmin jeon, adv. Mater technol.2018, 1700391. Meanwhile, blue light irradiation is also the most effective means for treating pediatric jaundice at present, and phototherapy products using semiconductor Light Emitting Diodes (LEDs) as light sources and integrated on flexible substrates are gradually emerging (US 6811563B2, US6596016B1, US6974224B 2), and even commercial phototherapy blankets for treating neonatal jaundice, such as BilitX products from Philips company (https:// www.philips.com.cn/healthcare/product/HC 866437/biltix-).

Various phototherapy devices aimed at anti-aging skin have been applied in beauty parlors, for example, LED masks have been commercialized on the market. These products have LED chips arranged in an array on the back of a plastic face mask. LEDs are high intensity point sources of light, often accompanied by heat generation. LED light sources generally incorporate heat sinks to reduce temperature, and the LEDs must be spaced apart for heat dissipation when used in an array format. This results in three disadvantages of the LED mask. First, such masks are thick and heavy because heat dissipation considerations necessitate the addition of a heat sink and must be located some distance from the person's face for safety. Some of these masks weigh up to 1.6 kilograms and the comfort of wearing on the face is compromised. Second, in the array arrangement, the LEDs are all independent at a certain position and have a distance therebetween, which results in non-uniform light emission. In cosmetic treatments, such uneven lighting may introduce uneven skin tone or require multiple treatments in different areas. Finally, to cover the entire face, a large number of LEDs, sometimes as many as 200 chips, need to be used. This increases the difficulty of LED screening, assembly and maintenance.

Products like using LEDs or laser arrays as light sources are also common in some hair growth cap products (https:// goods. Kala. Com/product/9018726. Html) and patent applications, such as those using lasers as light sources (CN 102015021B, CN110038231a, TW200718447 a), those using LEDs as light sources (US 20100106077A1, CN102784437B, CN106139413A, CN107676638A, CN109123868A, CN204502144U, CN206198484U, US10525278B 2), and those using LEDs or lasers as light sources but conducted by optical fibers (CN 108553765A, CN 109173075A).

In contrast, OLEDs are a surface light source, a cold light source, are not obtrusive, and have a thin and light profile that makes them very easy to integrate onto flexible substrates. This also makes OLEDs ideal light source options for wearable applications, and the related patent applications have covered various fields in recent years. Chinese patents CN205108772U, CN204951964U and chinese patent application US2012155057A1 all disclose the application of OLED light sources to wearable products for medical treatment. Chinese patent CN203694423U and chinese patent CN210009521U before the present inventor disclose the application of OLEDs to phototherapy masks; the inventor's prior patent application CN111481833A also mentions the use of OLEDs for the preparation of hair growth caps. However, the hair growing cap and the beauty mask are independent products, and at present, no product can provide two functions at the same time.

The modern life rhythm is increased, so that the alopecia becomes a problem of no sex distinction, alopecia areata (local sudden alopecia) can be caused sometimes by excessive pressure, and the hair loss phenomenon also can be frequently caused in the lactation period of women, so the hair growth is a relatively universal demand. On the other hand, the pursuit of beauty is not differentiated more and more, and now many men are also more and more image-focused and begin to use beauty products, so that beauty products with the effects of removing wrinkles, tightening the skin and the like are also in general demand.

A typical single-layer OLED device 100 is shown in FIG. 1 a. The OLED device 100 includes an anode layer 101, a Hole Injection Layer (HIL) 102, a Hole Transport Layer (HTL) 103, an Electron Blocking Layer (EBL) 104, an emission layer (EML) 105, a Hole Blocking Layer (HBL) 106, an Electron Transport Layer (ETL) 107, an Electron Injection Layer (EIL) 108, a cathode layer 109, and a capping layer (CPL) 110. In a bottom emission device, the anode layer 101 is a transparent or semi-transparent material, including but not limited to ITO, IZO, moOx (molybdenum oxide), etc., which has a transparency of typically more than 50%; preferably, the transparency is greater than 70%; the cathode layer 109 is a material with high reflectivity, including but not limited to Al, ag, etc., with reflectivity greater than 70%; preferably, the reflectivity is greater than 90%. In a top-emitting device, the anode layer 101 is a material or combination of materials with high reflectivity, including but not limited to Ag, ti, cr, pt, ni, tiN, and combinations of the above with ITO and/or MoOx (molybdenum oxide), typically with a reflectivity of greater than 50%; preferably, the reflectance is greater than 80%; more preferably, the reflectance is greater than 90%; the cathode layer 109 should be a translucent or transparent conductive material including, but not limited to, mgAg alloy, moOx, yb, ca, ITO, IZO or combinations thereof, typically having a transparency greater than 30%; preferably, the transparency is greater than 50%. Hole injection layer 102 may be a single layer of material, such as the commonly used HATCN; the hole injection layer 102 may also be a hole transport material doped with a p-type conductivity dopant material in a proportion, typically not higher than 5%, usually between 1% and 3%. The light-emitting layer 105 typically also comprises at least one host material and at least one light-emitting material. The electron blocking layer 104 and the hole blocking layer 106 are optional layers and the capping layer 110 is not required in the bottom-emitting device. The electron transport layer 107 may be a single layer of Yb, liQ, or LiF. FIG. 1b shows a schematic diagram of a multicolor OLED device 130, which can comprise a light-emitting layer 1051 and a light-emitting layer 1052, wherein the peak wavelength of the light-emitting layer 1051 can be between 600-750nm (red light emission) and the peak wavelength of the light-emitting layer 1052 can be between 750-1400nm (near infrared light emission), with the remaining layers unchanged. Note that the order of these two light emitting layers may be reversed, that is, the light emitting layer 1051 emits near infrared light and the light emitting layer 1052 emits red light. The OLED device with this structure can emit red light and near infrared light simultaneously. FIG. 1c is a schematic diagram of a variable color OLED device 120 having a light emitting layer 1053, a modulating layer 1054, and a light emitting layer 1055. The adjusting layer 1054 can adjust and control the movement of electron holes under different current densities, thereby realizing the adjustment and control of colors. For example, where the peak wavelength of the light emitting layer 1053 may be between 600-750nm (red light emitting), the peak wavelength of the light emitting layer 1055 may be between 750-1400nm (near infrared light emitting), at low current density the exciton recombination zone is predominantly near the cathode side, i.e., in the light emitting layer 1053, the OLED device 120 may emit red light; as the injection is gradually increased and the voltage and current density are increased, the exciton recombination zone moves toward the anode side and eventually enters the light emitting layer 1055, and the oled device 120 emits near infrared light. Of course, the light-emitting layer 1053 may emit near-infrared light and the light-emitting layer 1055 may emit red light, or vice versa. The structure of the color-changeable OLED device and the use of the adjusting layer can be referred to the patent applications CN111081891a and CN111081892A before the present inventor.

A typical stacked OLED device 200 is schematically shown in fig. 2, and includes an anode layer 201, a first light emitting unit 202, a first Charge Generation Layer (CGL) 203, a second light emitting unit 204, and a cathode layer 205. Here, the first light emitting unit 202 and the second light emitting unit 204 may further include a series of organic layers from the hole injection layer 102 to the electron injection layer 108 in the single-layer light emitting device 100, and the light emitting layers of the first light emitting unit 202 and the second light emitting unit 204 may be the same or different. The first light emitting unit 202 and the second light emitting unit 204 may emit lights of the same color, such as red lights each having a peak wavelength between 600-750 nm; the first light-emitting unit 202 and the second light-emitting unit 204 can also emit light of different colors, for example, the first light-emitting unit 202 emits red light, and the second light-emitting unit 204 emits near-infrared light with a peak wavelength between 750 and 1400nm, in which case the device 200 can emit red light and near-infrared light at the same time. The first charge generation layer 203 is typically composed of an n-type material and a p-type material, and a buffer layer may also be added, as described in patent application CN112687811 a. If the stacked device is a top-emitting device, a capping layer (not shown) may also be added over the cathode layer 205. Fig. 2 shows a 2-unit stacked device, and a 3-unit stacked device formed by a third light-emitting unit and a second charge generation layer can be added on the basis of the 2-unit stacked device. The fabrication of both single and stacked OLED devices is well known in the art and will not be described in detail herein.

One light source that may be used in a multi-functional hood is an Organic Light Emitting Device (OLED). A schematic cross-sectional view of an OLED light-emitting panel is shown in fig. 3a-3 d. In fig. 3a, the OLED light emitting panel 300 includes a substrate 301, an OLED device 310, a pair of contact electrodes 303 electrically connected to the OLED device 310, an encapsulating layer 302 exposing the contact electrodes 303, and a bonding structure 304 connecting the pair of contact electrodes 303 to an external driving circuit. The substrate 301 may be rigid, such as glass, or may be flexible; preferably, the substrate 301 is flexible, including but not limited to ultra-thin flexible glass, PET (polyethylene terephthalate), PEN (polyethylene naphthalate), PI (polyimide), and the like. In particular, the substrate 301 may be a material (e.g., PI material) that is previously coated on a support substrate in the form of a solution, cured and planarized for device fabrication. After the device is prepared, the device is peeled off from the supporting base plate by using a laser and is transferred to other flexible substrates according to requirements. OLED device 310 can be a bottom emitting device or a top emitting device, and preferably OLED device 310 is a top emitting device because of its higher light emitting efficiency. OLED device 310 can be a single layer structure or a stacked layer structure, and preferably OLED device 310 has a stacked layer structure because it has a longer lifetime at the same brightness and because the film layer is thicker, which is beneficial to improve the production yield. The organic material in OLED device 310 may be formed by evaporation in a vacuum chamber by thermal evaporation, or may be formed partially or entirely using a solution process, including but not limited to ink jet printing (ink jet printing), spin coating, organic vapor spray printing (OVJP), and the like. The encapsulation layer 302 may be glass adhered to the device by UV curable adhesive, preferably a thin film encapsulation layer, which is typically more than 10 μm thick, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, and is formed by Plasma Enhanced Chemical Vapor Deposition (PECVD), atomic Layer Deposition (ALD), printing, spin coating, etc. If both the substrate 301 and the encapsulation layer 302 are flexible, the entire OLED lighting panel is flexible; the contact electrode 303 may comprise at least one anode contact and at least one cathode contact. A front cover film 305 may be added to the OLED light emitting panel described above as shown in fig. 3 b. The front cover film 305 may be a Flexible Printed Circuit (FPC) board on which a pre-designed circuit is printed and electrically connected to the OLED device 310 through the adhesive structure 304. In another alternative, the adhesive structure 304 may be an FPC frame and the front cover film 305 may be a sheet of plastic film to provide mechanical support. A specific description of using an FPC board to drive an OLED light emitting panel can be found in patent application US20190376650A1, which is incorporated by reference in its entirety and is not within the scope of coverage of this application. The front cover film 305 may also include a light extraction layer. When OLED device 310 is a top-emitting device, front cover film 305 is transparent in the light-emitting area. The front cover film 305 may be a combination of the above. Additional thin film encapsulation layers 306 may be applied to one or both sides of the substrate 301 as shown in fig. 3 c. The front cover film may also be coated with an additional thin film encapsulation layer 306, but is not shown in this figure. In fig. 3d, a back cover film 307 is overlaid onto the substrate 301. The back cover film 307 may be used for mechanical support. When the OLED is a bottom-emitting device, the back cover film 307 may be a light extraction layer and transparent. The back cover film 307 may be a combination of the above. Such an OLED light-emitting panel is an OLED light source when electrically driven to form an electrical connection with an external device (regardless of whether it is in an on or off state), and is one of the essential components of the present invention.

The emission peak wavelength of the OLED light source used in the multifunctional head cover is between 400 and 2000 nm; preferably, the emission peak wavelength is between 500-1400 nm; more preferably, the emission peak wavelength is between 600-1000nm; still more preferably, the emission peak wavelength is between 630-970nm. The light with the peak wavelength of about 630nm has obvious therapeutic effect on the actinic keratosis, the light with the peak wavelength of about 650nm has hair growth effect, and the light with the peak wavelength of 805-970nm has effect on scar removal. For the periocular region, the most common medical purposes are anti-wrinkle, skin regeneration, macula removal, even anti-inflammation (e.g. hordeolum) and wound healing, scar reduction, etc. According to studies it has been shown (Daniel Barolet, semin Cutan Med Surg,27 227-238,2008) that light with a peak wavelength between 630-970nm has an effect on both of the above mentioned medical effects. In one embodiment, a multi-functional hood may select a peak wavelength of light, such as red light with a peak wavelength between 630-750 nm; in another embodiment, a multi-functional head cover emits light of different colors from OLED light emitting panels used on the head (including hairline area) and the eye/forehead, for example, red light with a peak wavelength between 630-700nm can be used on the head for hair growth, and near infrared light with a peak wavelength between 750-970nm can be used on the eye for wrinkle removal; even in another embodiment, a multi-functional head cover can integrate OLED light emitting panels emitting different wavelength bands in one area.

There are several ways to implement light with multiple different wavelength bands in a multifunctional hood: the first method is to design a pixelized layout on the same OLED light-emitting panel and then independently drive each pixel, or independently drive different groups after grouping the pixels. OLED luminescenceThe panels may be flexible or inflexible; preferably, a flexible OLED light-emitting panel is used, i.e. encapsulated with a flexible substrate and a thin film. The pixels here usually have a light-emitting area in the order of millimetres, i.e. a minimum dimension greater than 1mm ² Preferably greater than 5mm ² . For example, fig. 5a shows a schematic structural diagram of a flexible OLED light-emitting panel 500, which may include a flexible OLED substrate 501 on which a series of OLED devices 502 are prepared by patterning, and the devices share a same thin film encapsulation layer 503, in this case, each light-emitting unit is an OLED device, and the whole flexible OLED light-emitting panel is a light source. In this case, the metal wires may be arranged on the panel at the same time of preparing the anode or the cathode for electrically connecting the OLED devices 502, and the method of the metal wires is well known in the art and will not be described herein. The circuit control system is used for controlling different OLED devices, so that different devices can emit light with different colors, or the same device can work under different currents, and multiple colors can be realized. A variation of this scheme is the schematic structure of a flexible OLED lighting panel 510 as shown in fig. 5b, comprising a flexible OLED substrate 501, a series of OLED devices 502, but each device shares a separate encapsulation layer 513, and preferably a thin film encapsulation layer. At this time, the different OLED devices 502 can be connected through metal wiring, and can also be electrically connected through an FPC circuit board, thereby greatly improving the possibility of conductivity and circuit complexity. Also, a single or multiple OLED devices 502 can be independently driven through these electrical connections. Under the two conditions, if light with different colors is emitted, different device structures can be evaporated on different OLED devices by using a metal mask, and particularly, the material of a light emitting layer is changed; it is also possible to implement the colour change by means of the movement of the recombination zones at different operating points, with reference to the structures described in applications CN111081892A and CN111081891a, all using the same structure of independent unit multiple light emitting layers. Alternatively, the individual OLED panels may be arranged in an array, as shown in fig. 5c, where each panel comprises an individual substrate 521, an OLED device 502 and an individual encapsulating layer 513. The benefits of such an arrangementNon-flexible OLED light-emitting panels and/or non-flexible packaging layers can be selected, and as long as the area of each OLED light-emitting panel is small enough, the light source formed into an array still has certain flexibility. The individual OLED light emitting panels may be cut from the same motherboard, for example, using the same individual unit multi-light emitting layer structure, or may be reassembled by selecting different structures of devices from different motherboards. The scheme has the advantages that the device can be screened, the yield is improved, and the color diversity of products is also improved. The independent light-emitting panel shown in fig. 5c can be arranged and combined through FPC or front and back cover films, etc. as required to form a lattice which is physically connected with each other, and specifically refer to the method disclosed in CN208750423U, which is not in the scope of the present invention. Also, the panels may be independently controlled to apply different operating currents. The array arrangement can realize multicolor luminescence and zone control, such as hair growth phototherapy only on a local area at the top of the head or illumination only on an area with actinic keratosis hyperplasia. The local illumination can further reduce the power consumption and save energy.

Figures 4a-4c illustrate a schematic view of a multi-functional hood. Fig. 4a is an external schematic view of a multi-functional hood, comprising a housing 400, a head region 401 (head region 401 also comprises the hairline region), a forehead region 402, a periocular region 403 and a drive means 404. The housing 400 may be made of leather, textile, plastic, metal, etc., and the housing 400 is designed to be hollowed out in the area of the human eye to avoid blocking the view. Fig. 4b shows a schematic view 410 of the interior of a half of a multi-functional hood, where the head region is seen to have an OLED light panel 411 (also covering the hairline region), the forehead region is seen to have an OLED light panel 412, and the eye region is seen to have an OLED light panel 413. The gap between the light-emitting panel 411 and the light-emitting panel 412 in fig. 4b is only to illustrate two area boundaries. The OLED light-emitting panels may all be flexible, or may be formed by splicing small pieces of rigid panels as described above; preferably, however, the OLED light-emitting panel is flexible. The OLED light emitting panel 411, the OLED light emitting panel 412, and the OLED light emitting panel 413 may emit light in the same wavelength band or may emit light in different wavelength bands. For example, the OLED light emitting panel 411 can emit light with a peak wavelength between 630-750nm for hair growth treatment; the OLED light emitting panels 412 and 413 may emit light having a peak wavelength between 660-970nm for wrinkle reduction and skin tightening treatment.

In one embodiment, the wearer can use the mobile phone to control the on/off or brightness change of the OLED lighting panel 411, the OLED lighting panel 412, and the OLED lighting panel 413 through the bluetooth communication part in the driving device 404. Further, each light-emitting panel may be controlled in conjunction with an application program (APP). Fig. 4c shows a complete internal view 420 of the multifunctional hood, also including the OLED light panel 411 for the head, the OLED light panel 412 for the forehead, the OLED light panel 413 for the eye, and the driving device 404. The electrical contacts for the OLED light emitting panel 411, the OLED light emitting panel 412 and the OLED light emitting panel 413 may be hidden in the housing and electrically connected to the driving means 404, which are not shown here. In addition, the driving device 404 may be integrated in other suitable locations. It should be noted that although the OLED light emitting panel 411, the OLED light emitting panel 412, and the OLED light emitting panel 413 are shown separately in FIG. 4, a single flexible OLED light emitting panel could be used for the multi-functional hood. In addition, the multifunctional hood of fig. 4a-4c is similar to a batman mask, and is only illustrated here as an example, the outer shell of the hood can be designed into any other shape, such as the image of a person in a comic such as a captain, a lightening man, a cat, a grand monkey, a Nezha, a Aopy, etc., and the design with high identification degree is very popular in movie fans, and the wearer can not only feel abnormal but also have a sense of identity when using the multifunctional hood.

Similarly, fig. 6a and 6b show a schematic view of a multifunctional OLED head cover designed for a cat's female mask. Fig. 6a is an external view of a head cover, which includes a housing 600, the housing 600 can be further divided into a head area 601 (including a part of the forehead), a forehead area 602 (the forehead part includes a hairline area), a periocular area 603 and a driving device 604. Note that head region 601 may also include a portion of the forehead in this design, and forehead region 602 may also include the side of the head, such as the hairline region, without strict distinction, only that both head region 601 and forehead region 602 cover the head and forehead. The housing 600 is also hollowed out in the region of the eyes. Fig. 6b shows a schematic view 610 of the interior surface of the hood, where one can see an OLED light panel 612 covering the forehead portion and an OLED light panel 613 covering the eye perimeter, not shown, being an OLED light panel 611 covering the head. Note that the drive means 604 may also be integrated in other suitable areas, but the wireless (bluetooth) communication system of the drive means 604 is preferably integrated in such a sharply protruding part as shown in fig. 6a and 6 b. The hood shaped as a cat or woman mask is more suitable for women, wherein the OLED light-emitting panel of the forehead area 602 can effectively treat the retrogression of the hairline.

Fig. 7a and 7b show a schematic view of a multifunctional OLED head cover designed with a lightning-man mask as a model. Fig. 7a is a schematic external side view of a hood comprising a shell 700, which shell 700 is further divided into a head region 701, a forehead region 702, a periocular region 703 and a drive 704. The housing 700 is hollowed out at the eyes. Fig. 7b is a schematic view 710 of the interior surface of the hood, and it can be seen that the head region 701 is provided with an OLED light emitting panel 711, the forehead region 702 is provided with an OLED light emitting panel 712, and the eye circumference region 703 is provided with an OLED light emitting panel 713. Note that the gap between the OLED light emitting panel 711 and the OLED light emitting panel 712 in fig. 7b is only illustrative of two area boundaries. Likewise, the drive means 704 may be located anywhere within the housing, but its wireless (bluetooth) communication system is preferably integrated in the elongate pointed portion as shown in figures 7a and 7 b.

The multifunctional head cover disclosed by the invention is comfortable to wear because the light, thin and flexible OLED light-emitting panel is used as a phototherapy light source, and can perform wrinkle-removing and skin-firming treatment on the forehead area and the periocular area while performing hair-growing treatment on the head area, thereby achieving multiple purposes. The Bluetooth communication system in the driving device can be controlled by other commonly used electronic equipment such as a mobile phone, and the use is convenient. Finally, the mask using high-resolution designs such as super hero may attract more people and may also be effective in avoiding abnormal sensations when worn.
