[0032] With the continuous development of the medical aesthetics industry and people's increasing attention to beauty, many medical aesthetics instruments such as beauty lights and phototherapy masks have emerged on the market. When such medical aesthetics instruments are in use, they face people's faces directly, and the skin condition is improved by light of different wavelengths.

[0033] In the current phototherapy mask, it has a light source inside. The light source is generally integrated on a flexible circuit board, and the light-emitting side of the flexible circuit board is covered by a transparent film, and the other side of the flexible circuit board is covered by a non-transparent material. Therefore, in the production process, it is necessary to separately process and form two structural parts and then install them on both sides of the flexible circuit board respectively, and the processing steps are relatively complex.

[0034] To solve the above technical problems, the present utility model proposes a flexible mask 10, which includes a flexible circuit board 11 and a flexible wrapping layer 12 wrapped around the outer periphery of the flexible circuit board 11. The flexible mask 10 is attached to the face for use, and is hollowed out at the position corresponding to the eyes, and the light emitted by the lamp beads 112 on the flexible circuit board 11 will not cause harm to the eyes. Moreover, the flexible wrapping layer 12 can weaken the stimulation of the lamp beads 112 to the face and avoid facial burns.

[0035] Now, the flexible mask 10 provided by the embodiments of the present utility model will be described.

[0036] Please refer to Figures 1 to 3, the flexible facial mask 10 is used to be attached to the user's face. Generally speaking, the flexible facial mask 10 is similar in shape to an ordinary facial mask, and the flexible facial mask 10 is provided with hollowing holes for the facial features to be exposed. Specifically, the flexible facial mask 10 is provided with a first hollowing hole 101 at the eye part, so that the user's eyes are exposed; the flexible facial mask 10 is provided with a second hollowing hole 102 at the nose wing, so that the flexible facial mask 10 can closely adhere to the user's nose; the flexible facial mask 10 is provided with a third hollowing hole 103 at the mouth part, so that the user's mouth is exposed.

[0037] The flexible facial mask 10 includes a flexible circuit board 11 and a flexible wrapping layer 12, and the flexible wrapping layer 12 wraps around the outer periphery of the flexible circuit board 11.

[0038] The flexible circuit board 11 includes a board body 111, a plurality of lamp beads 112 and an electrical interface 113. The inside of the board body 111 has circuit traces, and the board body 111 can be flexibly deformed, so that the flexible facial mask 10 can be deformed and attached to the user's face. The lamp beads 112 and the electrical interface 113 are both arranged on the board body 111 and are both connected to the circuit traces inside the board body 111. The electrical interface 113 is exposed outside the flexible wrapping layer 12, so that the electrical interface 113 can be electrically connected to an external power source, and thus can provide electrical energy for the flexible circuit board 11. The lamp beads 112 are light sources and can emit light when powered on. Lights of different wavelengths have different optical effects on the human body, promoting the generation of collagen cells, thereby achieving the effects of sterilizing and removing acne, reducing wrinkles and brightening the skin tone. Specifically, lights of different wavelengths have different penetrations and effects. They are usually divided into red light, blue light, yellow light, etc. Each wavelength of light has a specific effect on different skin problems: Red light is usually used to stimulate the production of collagen, helps reduce fine lines and wrinkles, promotes skin elasticity and firmness. The wavelength of red light is longer and can penetrate deep into the bottom layer of the skin to promote blood circulation and metabolism. Blue light is suitable for treating acne and oily skin, reducing inflammation and helping to control sebum secretion. The wavelength of blue light is about 400 to 475 nanometers and can quickly kill Propionibacterium acnes, which is particularly effective in treating inflammatory acne. Yellow light can improve skin redness, reduce erythema and inflammation, and is usually used for sensitive skin and improving uneven skin tone. When using the flexible facial mask 10, the light-emitting side of the lamp beads 112 faces the face for attachment.

[0039] The flexible wrapping layer 12 is integrally injection-molded on the outer periphery of the flexible circuit board 11. Specifically, after the flexible circuit board 11 is manufactured, the flexible circuit board 11 is placed in an injection mold 20, and the rubber material is injected so that the rubber material wraps around the outer periphery of the flexible circuit board 11. After the rubber material solidifies, the flexible wrapping layer 12 is formed. The flexible wrapping layer 12 can also be deformed after molding, so that the flexible facial mask 10 can be attached to the user's face.

[0040] The flexible facial mask 10 in the above embodiments includes a flexible circuit board 11 and a flexible wrapping layer 12 wrapped around the outer periphery of the flexible circuit board 11. A plurality of lamp beads 112 are provided on the flexible circuit board 11. When the flexible facial mask 10 is attached to the face, the lamp beads 112 on the flexible circuit board 11 pass through the flexible wrapping layer 12 to irradiate the face, achieving a beauty effect. At the same time, the flexible wrapping layer 12 is integrally injection-molded on the outer periphery of the flexible circuit board 11, which can be formed in one injection molding, with relatively few components, and is convenient for processing without subsequent assembly.

[0041] In some embodiments of the present invention, please refer to Figure 2 , a plurality of lamp beads 112 are arranged in an array on the board body 111, so that each area of the flexible facial mask 10 has lamp beads 112, and each area of the face has an irradiation effect. The lamp beads 112 can be arranged in a circular array or a rectangular array.

[0042] Optionally, the distance between adjacent two lamp beads 112 is equal, so that the radiation received by each area of the face is uniform, and the overall beauty effect on the face is uniform.

[0043] In some embodiments of the present invention, a plurality of lamp beads 112 are divided into a plurality of lamp bead groups, and the number of lamp bead groups is at least two. The wavelengths of each lamp bead group are different, and different functions of beauty can be performed on the face respectively.

[0044] Optionally, the number of lamp bead groups is two, and the two lamp bead groups are a red light lamp group and a blue light lamp group respectively. When the red light lamp group needs to be used, the red light lamp group can be turned on, which helps to reduce fine lines and wrinkles and promote skin elasticity and firmness. When the blue light lamp group needs to be used, the blue light lamp group is turned on to reduce inflammation and help control sebum secretion. The red light lamp group and the blue light lamp group can also be turned on at the same time. In other embodiments, the number of lamp bead groups can also be three, four, etc.

[0045] Optionally, each lamp bead group is distributed in a different area, and different lamp bead groups perform different functions of beauty on different areas of the face. For example, one of the lamp bead groups is a blue light lamp group and is distributed in the T-zone of the face corresponding to the facial mask to control sebum secretion, and the other lamp bead group is a red light lamp group and is distributed in the cheek area of the face corresponding to the facial mask to promote skin elasticity and firmness.

[0046] Optionally, each lamp bead group is distributed at each position of the board body 111, that is to say, in the same area, lamp beads 112 with different wavelengths can be present at the same time, and different functions of beauty can be performed on the same position of the face. For example, the number of lamp bead groups is three, which are a red light lamp group, a blue light lamp group and a yellow light lamp group respectively, and the distribution modes of the three lamp bead groups are the same.

[0047] In some embodiments of the present utility model, at least part of the lamp beads 112 include light sources of multiple wavelengths, so that the lamp beads 112 are lamp beads 112 with adjustable spectrum. By controlling the on / off of each light source and the brightness, the wavelength of the light emitted by the lamp beads 112 can be adjusted, and thus different types of beauty treatments can be achieved.

[0048] In some embodiments of the present utility model, the electrical interface 113 is a conductive structure such as a connector with conductive pins, a gold finger, or a conductive patch, and it can be conductively connected to an external power source.

[0049] In some embodiments of the present utility model, the board body 111 has an electrical connection part extending out of the flexible wrapping layer 12, and the electrical interface 113 is located at the electrical connection part. Most of the structure of the board body 111 is inside the flexible wrapping layer 12, and the remaining part of the structure of the board body 111 extends out of the flexible wrapping layer 12 to be the electrical connection part. The electrical interface 113 is located at the electrical connection part, so the electrical interface 113 is exposed outside the flexible wrapping layer 12, and the external power source can directly contact the electrical interface 113 for conductive connection.

[0050] In some embodiments of the present utility model, the flexible wrapping layer 12 can be made of deformable materials such as silicone.

[0051] By extending the electrical connection part of the board body 111 to the outside of the flexible wrapping layer 12, the electrical interface 113 on the electrical connection part can be directly exposed, which is convenient for conductive connection with an external power source.

[0052] In some embodiments of the present utility model, the flexible wrapping layer 12 has an avoidance opening, and the electrical interface 113 is arranged opposite to the avoidance opening. In this embodiment, all parts of the board body 111 are wrapped by the flexible wrapping layer 12, and only an avoidance opening is provided at the electrical interface 113 to expose the electrical interface 113. The external power source extends into the avoidance opening to contact the electrical interface 113 for conduction.

[0053] By providing an avoidance opening on the flexible wrapping layer 12, the electrical interface 113 is exposed, which is convenient for the electrical interface 113 to be conductively connected to an external power source.

[0054] In some embodiments of the present utility model, a cover for shielding the electrical interface 113 is connected to the flexible wrapping layer 12, and the cover can be flipped relative to the flexible wrapping layer 12, so that the cover can be opened (the electrical interface 113 is exposed) or closed (the electrical interface 113 is shielded) by flipping.

[0055] Optionally, the flexible wrapping layer 12 and the cover are integrally injection-molded. One is to facilitate the processing of the cover, and the other is that the cover will not be lost.

[0056] In some embodiments of the present utility model, please refer to Figure 3, the flexible wrapping layer 12 includes a surface layer 121 and a substrate layer 122 respectively disposed on opposite sides of the flexible circuit board 11. The edges of the surface layer 121 and the substrate layer 122 are connected to each other to form an integrally injection-molded structure to wrap the flexible circuit board 11. The surface layer 121 is disposed on one side of the flexible circuit board 11, and the substrate layer 122 is disposed on the other side of the flexible circuit board 11 to shield both sides of the flexible circuit board 11. The edges of the surface layer 121 and the substrate layer 122 are connected to each other, and the connection part shields the edge of the flexible circuit board 11.

[0057] By shielding opposite sides of the flexible circuit board 11 with the surface layer 121 and the substrate layer 122 respectively, and shielding the edge of the flexible circuit board 11 through the connection part of the surface layer 121 and the substrate layer 122, the flexible circuit board 11 is wrapped in all directions to protect the flexible circuit board 11.

[0058] Among them, the surface layer 121 and the substrate layer 122 are injection-molded on opposite sides of the flexible circuit board 11 at the same time, and the processing of the flexible wrapping layer 12 can be completed only by one injection molding.

[0059] In some embodiments of the present utility model, the board body 111 is provided with through holes 114 penetrating through its opposite sides, and the through holes 114 are used for the flow of glue. When processing the flexible mask 10, first, the flexible circuit board 11 is processed and formed, and then the flexible circuit board 11 is placed into the injection mold 20, and glue is injected. Since flexible wrapping layers 12 are provided on both opposite sides of the board body 111, glue needs to be injected on both sides of the board body 111. The setting of the through holes 114 can enable the glue to move from one side of the board body 111 to the other side, avoiding the difficulty of glue flow and making the glue on both sides of the board body 111 more uniform.

[0060] Among them, the shape, quantity, and distribution of the through holes 114 are not limited here, and the through holes 114 need to avoid the circuit traces in the flexible circuit board 11.

[0061] In some embodiments of the present utility model, the board body 111 is provided with positioning holes for the injection mold 20 to position the flexible circuit board 11. When processing the flexible mask 10, first, the flexible circuit board 11 is processed and formed, and then the flexible circuit board 11 is placed into the injection mold 20, and glue is injected. The flexible circuit board 11 needs to be positioned with the injection mold 20 during installation. By providing positioning holes on the board body 111, it can cooperate with the positioning posts 24 in the injection mold 20 to accurately install the board body 111 in the injection mold 20 and ensure the quality of injection molding.

[0062] In some embodiments, the number of the positioning holes is multiple, and the number and distribution are not limited here. For example, the number of the positioning holes is four, which are respectively disposed on the top side, bottom side, left and right sides of the board body 111.

[0063] Please refer to Figures 4 to 6 Figures 4 to 6 , the present utility model further provides a flexible mask injection mold 20 for injection molding the flexible mask 10 in any of the above embodiments. The flexible mask injection mold 20 includes an upper mold 21 and a lower mold 22. A mold cavity for injection molding the flexible wrapping layer 12 and a glue injection port communicating with the edge of the mold cavity are formed between the upper mold 21 and the lower mold 22.

[0064] Both the upper mold 21 and the lower mold 22 have cavities. When the upper mold 21 and the lower mold 22 are closed together, a mold cavity is formed inside. The flexible circuit board 11 is located in the mold cavity, and the glue material enters the mold cavity from the glue injection port, so that the glue material entering the mold cavity adheres to the surface of the flexible circuit board 11.

[0065] Specifically, when injecting the flexible mask 10, the flexible circuit board 11 is positioned in one of the upper mold 21 or the lower mold 22, and then the other one moves to close the mold, fixing the flexible circuit board 11 in the injection mold 20. Then, the glue material is injected. After the material injection is completed and solidified, the upper mold 21 and the lower mold 22 move relative to each other, and the mold is opened, and then the injection-molded flexible mask 10 can be taken out.

[0066] The flexible mask injection mold 20 provided by the present utility model directly forms the flexible wrapping layer 12 on the outer periphery of the flexible circuit board 11 by an integral injection molding method. The production method is simple, and the flexible circuit board 11 can be wrapped and sealed, and the protection degree of the flexible circuit board 11 is relatively high.

[0067] In some embodiments of the present utility model, please refer to Figures 4 to 6 Figures 4 to 6 , support columns 23 are provided on the side of the upper mold 21 and / or the lower mold 22 facing the mold cavity. The support columns 23 are used to support the flexible circuit board 11, and the height of the support columns 23 extending into the mold cavity is less than the height of the glue injection port. Since flexible wrapping layers 12 are provided on both opposite sides of the board body 111, both sides of the flexible circuit board 11 need to be suspended in the mold cavity of the injection mold 20. This embodiment includes the following three situations: support columns 23 are provided on the side of the upper mold 21 facing the mold cavity to support one side of the flexible circuit board 11; support columns 23 are provided on the side of the lower mold 22 facing the mold cavity to support one side of the flexible circuit board 11; support columns 23 are provided on the sides of both the upper mold 21 and the lower mold 22 facing the mold cavity to support both opposite sides of the flexible circuit board 11, preventing the flexible circuit board 11 from collapsing towards any side. The height of the support columns 23 extending into the mold cavity is less than the height of the glue injection port, which can be understood as that the top of the glue injection port extends over the flexible circuit board 11, so that when injecting glue, the glue material enters from both sides of the flexible circuit board 11 at the same time, which can improve the injection molding quality.

[0068] By providing the support posts 23, each part of the flexible circuit board 11 can be maintained at a preset position, preventing the flexible circuit board 11 from deforming due to its soft material and collapsing towards one side.

[0069] In some embodiments, the number of support posts 23 on the upper mold 21 is multiple, and they are equally spaced and arranged on the inner wall of the upper mold 21.

[0070] In some embodiments, the number of support posts 23 on the lower mold 22 is multiple, and they are equally spaced and arranged on the inner wall of the lower mold 22.

[0071] In some embodiments, the support posts 23 on the upper mold 21 and the support posts 23 on the lower mold 22 are arranged opposite to each other, so that both opposite sides of the same position of the flexible circuit board 11 can be supported, and the shaking of the flexible circuit board 11 in the mold can be reduced to a certain extent.

[0072] In some embodiments, the support posts 23 on the upper mold 21 and the support posts 23 on the lower mold 22 are arranged staggeredly, so that more positions of the flexible circuit board 11 can be supported by the support posts 23, and the possibility of deformation of the flexible circuit board 11 can be further reduced.

[0073] In some embodiments of the present invention, please refer to Figures 4 to 6 , positioning posts 24 are provided on the side of the upper mold 21 and / or the lower mold 22 facing the mold cavity, and the positioning posts 24 are used to position the flexible circuit board 11. Corresponding positioning holes are provided on the flexible circuit board 11. This embodiment includes the following three situations: positioning posts 24 are provided on the side of the upper mold 21 facing the mold cavity. In the injection molding step, the flexible circuit board 11 can be installed on the upper mold 21 and positioned by the positioning posts 24 on the upper mold 21; positioning posts 24 are provided on the side of the lower mold 22 facing the mold cavity. In the injection molding step, the flexible circuit board 11 can be installed on the lower mold 22 and positioned by the positioning posts 24 on the lower mold 22; positioning posts 24 are provided on the side of both the upper mold 21 and the lower mold 22 facing the mold cavity. In the injection molding step, the flexible circuit board 11 can be installed on the upper mold 21 or the lower mold 22, and the positioning posts 24 on both sides of the flexible circuit board 11 respectively position it.

[0074] By providing the positioning posts 24, when the flexible circuit board 11 is installed in the injection mold 20, its position can be accurate, avoiding deviation, and ensuring the injection molding quality of the flexible wrapping layer 12.

[0075] In some embodiments, the number of positioning posts 24 on the upper mold 21 is multiple, and they are arranged near the edge of the upper mold 21.

[0076] In some embodiments, the number of positioning posts 24 on the lower mold 22 is multiple, and they are arranged near the edge of the lower mold 22.

[0077] In some embodiments of the present utility model, please refer to Figures 4 to 6 , the support post 23 and / or the positioning post 24 can move towards or away from the mold cavity. The support post 23 and the positioning post 24 are equivalent to inserts of the injection mold 20, and can move to be protruded from the cavity wall of the mold cavity or move to be flush with the cavity wall of the mold cavity. When injecting the flexible wrapping layer 12, the support post 23 and the positioning post 24 first move to be protruded from the cavity wall of the mold cavity, and then the mold is closed for injection. After the rubber material basically wraps the flexible circuit board 11 and forms a certain support for the flexible circuit board 11, the support post 23 and the positioning post 24 can be moved to be flush with the cavity wall of the mold cavity, and the rubber material will quickly fill the holes corresponding to the support post 23 and the positioning post 24, so that the surface of the flexible wrapping layer 12 is complete.

[0078] When the support post 23 and the positioning post 24 are fixedly arranged, after injection molding, grooves will be correspondingly formed on the flexible wrapping layer 12, which not only results in poor integrity of the flexible mask 10, but also reduces the degree of sealed wrapping of the flexible circuit board 11. By making the support post 23 and the positioning post 24 movable, the rubber material can quickly fill the grooves when it is in an uncured state, maintaining the integrity of the flexible wrapping layer 12.

[0079] In some embodiments, a first through hole communicating with the mold cavity is formed on the upper mold 21 and / or the lower mold 22. The support post 23 is adjustably installed in the first through hole. The support post 23 has a support position for extending into the mold cavity to support the flexible circuit board 11 and a first retracted position for retracting to be flush with the inner wall of the mold cavity in the first through hole; a second through hole communicating with the mold cavity is formed on the upper mold 21 and / or the lower mold 22. The positioning post 24 is adjustably installed in the second through hole. The positioning post 24 has a working position for passing through the positioning hole of the flexible circuit board 11 to position the flexible circuit board 11 and a second retracted position for retracting to be flush with the inner wall of the mold cavity in the second through hole.

[0080] The support post 23 has a support position and a first retracted position. When the support post 23 is in the support position, it abuts against the corresponding surface of the flexible circuit board 11 to support the flexible circuit board 11.

[0086] In some embodiments of the present utility model, please refer to Figure 5 and Figure 6 , a convex structure 25 is formed on the upper mold 21 or the lower mold 22 protruding toward the mold cavity. The convex structure 25 is used to closely adhere to the electrical interface 113. The convex structure 25 occupies the space in the mold cavity, so that no glue material flows into the electrical interface 113. In this way, the electrical interface 113 can be prevented from being wrapped by the glue material, and thus the electrical interface 113 is exposed.

[0087] In some embodiments, the electrical interface 113 of the flexible circuit board 11 faces the upper mold 21, and the upper mold 21 protrudes toward the mold cavity to form a convex structure 25 to closely adhere to the electrical interface 113.

[0088] In some embodiments, the electrical interface 113 of the flexible circuit board 11 faces the lower mold 22, and the lower mold 22 protrudes toward the mold cavity to form a convex structure 25 to closely adhere to the electrical interface 113.

[0089] In some embodiments of the present utility model, a partition structure 26 is formed on the upper mold 21 and / or the lower mold 22 protruding toward the mold cavity. The partition structure 26 is used to form at least one of the eye part, the mouth part, and the nasal wing of the flexible wrapping layer 12. The flexible facial mask 10 is similar to a common patch facial mask and is used to fit the human face. Therefore, it correspondingly has parts such as the eye part, the mouth part, and the nasal wing. The flexible facial mask 10 is provided with hollow holes at the eye part, the mouth part, and the nasal wing. That is to say, the flexible circuit board 11 is provided with hollow holes at the eye part, the mouth part, and the nasal wing. The partition structure 26 makes the flexible wrapping layer 12 also form hollow holes at the corresponding positions.

[0090] By providing the partition structure 26, a first hollow hole 101, a second hollow hole 102, and a third hollow hole 103 can be respectively formed at the eye part, the nasal wing, and the mouth part of the partition structure 26, so that parts such as the eyes and the mouth are exposed, and the flexible facial mask 10 fits the face more closely.

[0091] In some embodiments, the upper mold 21 protrudes toward the mold cavity to form a partition structure 26, and the side of the partition structure 26 away from the upper mold 21 directly contacts the inner wall of the lower mold 22.

[0092] In some embodiments, the lower die 22 protrudes toward the mold cavity to form a partition structure 26, and the side of the partition structure 26 away from the lower die 22 is directly connected to the inner wall structure of the upper die 21.

[0093] In some embodiments, both the upper die 21 and the lower die 22 protrude toward the mold cavity to form partition structures 26, and the two partition structures 26 abut against each other, and can also form corresponding hollow holes on the flexible wrapping layer 12.

[0094] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
