Description

Technical Field

[0001] The utility model relates to the technical field of beauty physiotherapy, and particularly provides a flexible light therapy mask. Background Art

[0002] Generally, a beauty mask uses radio frequency to emit energy to achieve the effect of beauty care on the user's face. Generally, the beauty mask includes a mask body and a light emitting part arranged in the mask body. By emitting a light beam in a certain wavelength band, the light therapy method is used to play a corresponding beauty and health care role on the user's face.

[0003] However, most of the mask bodies of the current beauty masks are hard three-dimensional masks, which need to be customized when facing different user groups. Therefore, their versatility is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flexible light therapy mask, aiming to solve the problem that the existing flexible light therapy mask is difficult to adapt to different user groups.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An embodiment of the present application provides a flexible light therapy mask, including:

[0007] A main body part, the main body part is flexible, the main body part has a first surface, the first surface is recessed inward to form a receiving groove for receiving the user's face, the first surface has flexibility and light transmittance, and the middle part of the receiving groove along the width direction of the main body part has a first area, and the first area is used to correspondingly fit the skin corresponding to the forehead, nose, lips and chin of the user's face in the non-bound state;

[0008] A light emitting part for performing light therapy on the skin, the light emitting part is arranged in the main body part, and the light beam emitted by the light emitting part passes through the first surface to the surface of the user's facial skin.

[0009] The beneficial effects of the utility model: For the flexible light therapy mask provided by the utility model, a receiving groove for receiving the user's face is formed on the main body part, and a first surface is formed in the middle of the receiving groove, and the first surface in direct contact with the skin of the user's face has flexibility to meet the requirements of the fitting degree with the faces of different people. At the same time, the first area of the first surface can fit the skin corresponding to the forehead, nose, lips and chin of the user's face in the non-bound state, further improving the adaptability of the flexible light therapy mask to meet the use needs of different users.

[0010] In some embodiments, the accommodating groove further has two second regions, and the two second regions are respectively located on opposite sides of the first region along the width direction of the main body portion. The second regions are used to correspondingly partially fit the skin of the cheeks in the unbound state; and the second regions are used to correspondingly completely fit the skin of the cheeks in the bound state.

[0011] By adopting the above technical solution, in the width direction of the main body portion, second regions are formed on opposite sides of the first region. The second regions are mainly used to correspondingly partially fit the skin of the cheeks of the user's face when the mask is in the unbound state, and when the mask is in the bound state.

[0012] In some embodiments, the accommodating groove further has two third regions, and the two third regions are respectively located on opposite sides of the accommodating groove along the width direction of the main body portion. The third regions are used to deform towards both sides of the user's face to fit the skin in the bound state.

[0013] By adopting the above technical solution, a third region is provided on each side of the two second regions away from the first region. The third regions are in a fitting state with the skin on both sides of the user's face in the bound state.

[0014] In some embodiments, the width of the first region gradually decreases from the middle of the length direction of the main body portion to each end of the main body portion; and / or; the width of the third region gradually decreases from the middle of the length direction of the main body portion to each end of the main body portion; and / or, the first connecting line between the first region and the second region is arc-shaped, and / or, the second connecting line between the second region and the third region is arc-shaped.

[0015] By adopting the above technical solution, in terms of the layout form, the first region shows a distribution of "large in the middle and small at both ends" in the length direction of the main body portion; the third region shows a distribution of "large in the middle and small at both ends" in the length direction of the main body portion; the first connecting line between the first region and the second region is arc-shaped; the second connecting line between the second region and the third region is arc-shaped; in the tightened state, the tension can be evenly distributed so that the first region, the second regions, and the third regions can fit the skin of the user's face.

[0016] In some embodiments, two connection positions are symmetrically provided on the main body portion, and the two connection positions correspond to the two third regions one by one. The connection positions are used for connecting the binding straps. In the bound state, the first region, each of the second regions, and each of the third regions all fit the skin of the user's face.

[0017] By adopting the above technical solution, the binding strap is connected to the connection position, so that the flexible light therapy mask is fixed on the user's head by tying, and in the bound state, the first area, each second area, and each third area are all attached to the skin of the user's face.

[0018] In some embodiments, a flange is formed at the edge of the main body. In the unbound state, the flange is in the same plane as the third area, and the flange is used to fit the facial edge contour in the bound state.

[0019] By adopting the above technical solution, the flange is the outer edge part of the main body. In the unbound state, the flange is in the same plane as the third area, that is, in a flat state, and in the bound state, the flange is the same as the third area, and thus will fit the facial edge contour of the user.

[0020] In some embodiments, the main body and the light emitting part are integrally formed.

[0021] By adopting the above technical solution, the main body and the light emitting part can be integrally formed by the in-mold injection process. In this way, the combination of the main body and the light emitting part is better.

[0022] In some embodiments, the main body includes a light-facing layer and a backlight layer that are stacked. The end face of the light-facing layer facing away from the backlight layer is the first face, and the end face of the backlight layer facing away from the light-facing layer is the second face. The second face has non-light-transmitting properties, and the light emitting part is disposed between the light-facing layer and the backlight layer.

[0023] By adopting the above technical solution, the main body is composed of two independent parts, namely, the light-facing layer and the backlight layer. That is, the main body is a split design, and the light emitting part is disposed between the light-facing layer and the backlight layer by sandwiching. In this way, it is convenient to maintain the light emitting part in the later stage.

[0024] In some embodiments, the light emitting part includes a flexible circuit board, lamp beads disposed on the flexible circuit board, and a connection interface electrically connected to the flexible circuit board. The flexible circuit board is disposed inside the main body, and the lamp beads face the first face.

[0025] By adopting the above technical solution, the flexible circuit board has a certain deformability and is easy to deform correspondingly with the main body to meet the requirement of fitting the user's face. At the same time, the flexible circuit board controls the circuit of the lamp beads, so that each lamp bead emits light beams of the same or different wavelengths; the connection interface is used for electrically connecting to an external power supply to supply power to the flexible circuit board.

[0026] In some embodiments, a plurality of strip-shaped notches are formed inwardly on the edge side of the flexible circuit board.

[0027] By adopting the above technical solution, a plurality of strip-shaped notches can be formed on the edge side of the flexible and delicate circuit board, so as to reduce the probability of wrinkles occurring when the flexible circuit board changes from a planar state to a three-dimensional state, and improve the installation stability of the flexible circuit board.

[0044] Generally, the mask body of a beauty mask is either a flat mask made of flexible silicone, using its deformability to cover the contour of the user's face for light therapy; or made of a hard material, using its good forming performance to meet the corresponding support requirements.

[0045] However, regardless of the type of face mask used, there are corresponding problems with the face mask body. For example, the support performance of the flat face mask body is poor. Under the binding action of the straps, its overall deformation is large, and the fitting degree of the parts corresponding to the user's forehead and chin becomes poor, with a large gap, and the light leakage phenomenon at this place is relatively serious; or, the hard face mask body has a high specificity and is usually used for customized services, with poor versatility.

[0046] In view of this, the present application provides a flexible light therapy face mask, in which a receiving groove adapted to the user's facial contour is formed on the first surface of the main body. At the same time, the main body part is flexible, and the first surface has flexibility and light transmittance to meet the requirements of the fitting degree with the faces of different people. At the same time, the first area of the receiving groove can be attached to the skin corresponding to the forehead, nose, lips and chin of the user's face in the non-binding state, further improving the adaptability of the flexible light therapy face mask to meet the usage needs of different users.

[0047] Please refer to Figures 1 to 5 , an embodiment of the present application provides a flexible light therapy face mask 100, including a main body part 10 and a light emitting part 20.

[0048] Among them, the main body part 10 is the main structure of the flexible light therapy face mask 100, which plays a role in carrying the light emitting part 20 and is also used for wearing and adapting to the user's face. The main body part 10 should be shaped to fit the user's facial contour, similar to a thin cover body. The light emitting part 20 is a light source that emits light beams in corresponding bands, similar to a lamp board with multiple LED lamp beads.

[0049] The main body part 10 is flexible. The main body part 10 has a first surface 10a. The first surface 10a is recessed inward to form a receiving groove 10f for accommodating the user's face. The first surface 10a has flexibility and light transmittance. The receiving groove 10f has a first area 10a1 in the middle along the width direction X of the main body part 10. In the non-binding state, the first area 10a1 correspondingly fits the skin corresponding to the forehead, nose, lips and chin of the user's face.

[0050] Understandably, the flexibility of the main body 10 means that during the binding process, both sides of the main body 10 in the width direction X can be deformed and bent to closely adhere to the skin, which is the bendable characteristic of sheet materials such as soft silicone or rubber; the first surface 10a is the end surface of the main body 10 facing the user's face in the usage state of the flexible light therapy mask 100. A receiving groove 10f is formed on the first surface 10a, making the overall flexible light therapy mask have corresponding three-dimensionality. At the same time, the flexibility of the first surface 10a means that the first surface 10a has good deformability and can conform to the contour of the user's face. Especially after being stretched, it fits better with the skin of the user's face, thereby improving the adaptability of the flexible light therapy mask 100. Here, the main body 10 can be but is not limited to being formed by liquid silicone injection molding, and the material of the first surface 10a can be silicone, polysiloxane, etc.

[0051] At the same time, the middle part of the receiving groove 10f in the width direction of the main body has a first area 10a1, which means that in the width direction X of the main body 10, the first area 10a1 is formed at the central position of the receiving groove 10f. This first area 10a1 corresponds to the forehead, nose, lips, and chin of the user's face after the flexible light therapy mask 100 is worn. Here, the non-binding state means that the main body 10 is in a state without external force stretching, that is, when the main body 10 is worn on the user's face, corresponding stretching elongation is required. Therefore, in the non-stretched state, the first area 10a1 of the receiving groove 10f can already conform to the skin corresponding to the forehead, nose, lips, and chin of the user's face. The "conformity" described here means complete conformity, and there is no gap or the gap is very small between the first area 10a1 and the skin of the user's face and can be ignored.

[0052] The light-emitting part 20 is used for light therapy on the skin. The light-emitting part 20 is arranged inside the main body 10, and the light beam emitted by the light-emitting part 20 passes through the first surface 10a to the skin surface of the user.

[0053] Understandably, the light-emitting part 20 being arranged inside the main body 10 means that the light-emitting part 20 is embedded inside the main body 10, that is, the outer surface of the light-emitting part 20 is covered by the main body 10. At least, the light-emitting part 20 is exposed to the outside from the first surface 10a.

[0054] At the same time, due to the light-transmitting property of the first surface 10a, the light beam emitted by the light-emitting part 20 passes through the first surface 10a to the skin surface of the user.

[0055] The flexible phototherapy mask 100 provided by the present utility model has a receiving groove 10f on its main body 10 for receiving the user's face. Moreover, the first surface 10a that directly contacts the skin of the user's face is flexible to meet the requirements of fitting different people's faces. At the same time, the first region 10a1 of the first surface 10a can fit the skin corresponding to the forehead, nose, lips, and chin of the user's face in the unbound state, further improving the adaptability of the flexible phototherapy mask to meet the usage needs of different users.

[0056] Please refer to Figure 5 , in some embodiments, the receiving groove 10f also has two second regions 10a2, and the two second regions 10a2 are respectively located on the opposite sides of the first region 10a1 along the width direction X of the main body 10. In the unbound state, each second region 10a2 correspondingly partially fits the skin of the user's cheeks, and, in the bound state, each second region 10a2 is used to correspondingly fully fit the skin of the cheeks.

[0057] Similarly, the unbound state here also refers to the state where the main body 10 is not stretched by an external force, that is, when the main body 10 is worn on the user's face, corresponding stretching elongation is required. At the same time, since the second regions 10a2 are formed on the opposite sides of the first region 10a1, then, each second region 10a2 correspondingly partially fits the skin of the user's cheeks. The "partial fit" described here means that the degree of fit with the skin of the user's face is relatively poor, that is, there is a corresponding gap between the second region 10a2 and the skin of the user's face.

[0058] Here, the bound state refers to the state where the main body 10 is in a stretched state under the action of an external force. That is, when the main body 10 is worn on the user's face, it is stretched and elongated.

[0059] Please refer to Figure 5 , in some embodiments, the receiving groove 10f also has two third regions 10a3, and the two third regions 10a3 are respectively located on the opposite sides of the receiving groove 10f along the width direction X of the main body 10. In the unbound state, each third region 10a3 is separated from the skin of the user's face; and, in the bound state, the third region 10a3 is used to deform towards both sides of the user's face to fit the skin.

[0060] It can be understood that the unbound state here also refers to the state where the main body 10 is not stretched by an external force, that is, when the main body 10 is worn on the user's face, corresponding stretching elongation is required. At the same time, a third region 10a3 is provided on each side of the two second regions 10a2 away from the first region 10a1. The "separated state" described here means that the third region 10a3 does not contact the skin of the user's face, or the contact degree is very small.

[0061] Similarly, the binding state here also means that the main body 10 is in a stretched state under the action of external force. That is, when the main body 10 is worn on the user's face, it is stretched by being pulled. In the binding state, the third area 10a3 is used to deform toward both sides of the user's face to fit the skin, which should mean that the third area 10a3 is completely in contact with the skin surface on both sides of the user's face.

[0062] Please refer to Figure 5 In some embodiments, the width of the first region 10a1 gradually decreases from the middle of the length direction Y of the main body 10 to each end of the main body 10; and / or, the width of the third region 10a3 gradually decreases from the middle of the length direction Y of the main body 10 to each end of the main body 10; and / or, the first connecting line 10a4 between the first region 10a1 and the second region 10a2 is arc-shaped, and / or, the second connecting line 10a5 between the second region 10a2 and the third region 10a3 is arc-shaped.

[0063] It can be understood that the first connecting line 10a4 between the first area 10a1 and the second area 10a2 is arc-shaped, which can evenly distribute the tension of the first area 10a1 when it is in a taut state, so that the second area 10a2 can fit the skin of the cheek of the user's face; similarly, the second connecting line 10a5 between the second area 10a2 and the third area 10a3 is arc-shaped, which can evenly distribute the tension of the second area 10a2 when it is in a taut state, so that the third area 10a3 can fit the skin of the user's face.

[0064] Furthermore, the width of the first area 10a1 gradually decreases from the middle of the main body 10 in the length direction Y to each end of the main body 10, which means that from the appearance point of view, the first area 10a1 presents a "large in the middle and small at both ends" structure in the length direction Y of the main body 10; then, in the bound state, the force applied to the first area 10a1 can change uniformly in a gradient, so that the first area 10a1 can fit the skin corresponding to the user's forehead, nose, lips and chin.

[0065] Also, the width of the third area 10a3 gradually decreases from the middle of the main body 10 in the length direction Y to each end of the main body 10, which means that from the appearance point of view, the third area 10a1 presents a "large in the middle and small at both ends" structure in the length direction Y of the main body 10; then, in the bound state, the force on the third area 10a3 can change evenly in a gradient, so that the third area 10a1 can fit the user's facial skin.

[0066] Optionally, in terms of the shape structure, it can be selected that only the first connecting line 10a4 is arc-shaped, or it can also be selected that only the second connecting line 10a5 is arc-shaped, or it can be selected that both the first connecting line 10a4 and the second connecting line 10a5 are arc-shaped; or, the width of the first region 10a1 gradually decreases from the middle of the length direction Y of the main body 10 to each end of the main body 10; or, the width of the third region 10a3 gradually decreases from the middle of the length direction Y of the main body 10 to each end of the main body 10; or, the above-mentioned solutions can also be combined arbitrarily in pairs, any three of them can be selected for combination, and all the solutions can be selected for combination.

[0067] It should be noted that the first connecting line 10a4 and the second connecting line 10a5 may not actually exist on the final product. Of course, the specific positions of the first connecting line 10a4 and the second connecting line 10a5 can also be shown by additionally adding auxiliary lines.

[0068] Please refer to Figure 1 and Figure 5 , in some embodiments, two connection positions 10e are symmetrically provided on the main body 10, each connection position 10e corresponds to the third region 10a3, and the connection position 10e is used for the binding strap to pass through. In the bound state, the first region 10a1, each second region 10a2, and each third region 10a3 are all attached to the skin of the user's face.

[0069] It can be understood that the connection position 10e can be a button or a strip-shaped hole, etc. When the connection position 10e is a strip-shaped hole and the binding strap passes through the connection position 10e to form a connection point position, when the flexible light therapy mask is fixed on the user's head by tying, the flexible light therapy mask is in a stretched and elongated state as a whole.

[0070] It should be noted that the direction of the pulling force is on the line connecting the two connection positions 10e and passes through the first region 10a1, each second region 10a2, and each third region 10a3. Therefore, in the bound state, the first region 10a1, each second region 10a2, and each third region 10a3 are all attached to the skin of the user's face.

[0071] Please refer to the figure. In some embodiments, a peripheral edge 10g is formed at the edge of the main body 10. The peripheral edge 10g is in the same plane as the third region 10a3 in the non-bound state, and the peripheral edge 10g is used to fit the facial edge contour in the bound state.

[0072] It can be understood that the peripheral edge 10g is the outermost edge of the main body 10. In the non-bound state, the peripheral edge 10g is in the same plane as the third region 10a3, that is, both are in a flat state. And in the bound state, the peripheral edge 10g is stretched and then attached to the user's facial edge contour.

[0073] In some embodiments, the main body portion 10 and the light emitting portion 20 are integrally formed.

[0074] Understandably, the light emitting portion 20 is disposed in a mold, and the main body portion 10 is formed on the outer surface of the light emitting portion 20 by in-mold injection molding.

[0075] In this way, the forming efficiency of the two is high, and the combination of the main body portion 10 and the light emitting portion 20 is better.

[0076] Please refer to Figure 1 and Figure 4 , in some embodiments, the main body portion 10 includes a light-facing layer 11 and a backlight layer 12 which are stacked. The end face of the light-facing layer 11 facing away from the backlight layer 12 is the first face 10a, and the end face of the backlight layer 12 facing away from the light-facing layer 11 is the second face 10b. The light emitting portion 20 is disposed between the light-facing layer 11 and the backlight layer 12, or the second face 10b has non-light-transmitting properties.

[0077] Understandably, the light-facing layer 11 is used to contact the user's face, and the light beam emitted by the light emitting portion 20 can pass through the light-facing layer 11, and the backlight layer 12 plays a corresponding supporting role for the light-facing layer 11.

[0078] Here, the flexibility of other parts of the light-facing layer 11 can be defined to be the same as that of the first face 10a, that is, the light-facing layer 11 can be integrally formed from the same material at one time, or it can also be defined that after the light-facing layer 11 is formed, a layer of structure is coated on its surface to form the first face 10a. Similarly, the flexibility of other parts of the backlight layer 12 is the same as that of the second face 10b, that is, the backlight layer 12 can be integrally formed from the same material at one time, or it can also be defined that after the backlight layer 12 is formed, a layer of structure is coated on its surface to form the second face 10b.

[0079] The second face 10b having non-light-transmitting properties means that the light beam of the light emitting portion 20 is difficult to emit to the outside from the second face 10b.

[0080] The connection methods between the light-facing layer 11 and the backlight layer 12 include but are not limited to bonding, snap connection, screw connection, welding, etc.

[0081] Exemplarily, the light-facing layer 11 and the backlight layer 12 are connected by snap connection, that is, corresponding snap connection structures and snap-fit structures are provided on the light-facing layer 11 and the backlight layer 12. In this way, the light-facing layer 11 and the backlight layer 12 can be separated, which is convenient for taking out the light emitting portion 20 clamped between the two, so as to realize the secondary utilization of the light emitting portion 20.

[0082] Of course, in other embodiments, the light-facing layer 11 and the backlight layer 12 are connected by welding. Specifically, welding is performed at the connection between the two. In this way, the overall stability of the flexible light therapy mask 100 is higher.

[0083] Exemplarily, in the actual manufacturing process, the deformability of the first surface 10a and the deformability of the second surface 10b can be designed differently, while the material flexibility of the portion of the main body 10 between the two surfaces remains unchanged. For example, the flexibility of the material of the first surface 10a is A, the flexibility of the material of the second surface 10b is B, and the material of the portion of the main body 10 between the two surfaces is C. In terms of flexibility, A is greater than C, and C is greater than or equal to B.

[0084] In other embodiments, the material flexibility of the portion of the main body 10 between the two surfaces can also be gradually changed. For example, in the direction from the first surface 10a to the second surface 10b, the material flexibility of the portion of the main body 10 between the two surfaces gradually decreases, that is, the closer it is to the second surface 10b, the smaller the flexibility of its material. In terms of technology, the main body 10 with such a gradually changing flexibility can be realized by a multi-layer and multi-time injection molding method.

[0085] Of course, in some embodiments, the flexibility of the main body 10 and the backlight portion is the same, that is, the flexibility of the first surface 10a and the second surface is also the same, and it is injection molded at one time with the same material.

[0086] In summary, the main body 10 is composed of two independent parts, namely the light-emitting layer 11 and the backlight layer 12, that is, the main body 10 is a split design, and the light-emitting portion 20 is arranged between the light-emitting layer 11 and the backlight layer 12 by a sandwiching method. In this way, it is convenient to maintain and reuse the light-emitting portion 20 in the later stage.

[0087] Please refer to Figure 1 and Figure 2 , in some embodiments, the backlight layer 12 has a third surface 10c facing the light-emitting layer 11, and the third surface 10c is recessed inward to form a groove 10d for accommodating the light-emitting portion 20 and the light-emitting layer 11.

[0088] It can be understood that by forming the groove 10d on the third surface 10c, the backlight layer 12 can directly carry and support the light-emitting layer 11. At the same time, the overall thickness of the flexible light therapy mask 100 is also thinner.

[0089] Here, the groove depth and groove profile of the groove 10d should be adapted to the thickness and outer contour of the light-emitting layer 11. Then, the combination degree of the two is higher, and the joint is tighter.

[0090] In summary, by providing the groove 10d on the backlight layer 12 and using the groove 10d to accommodate the light-emitting portion 20 and the light-emitting layer 11, the overall thickness of the flexible light therapy mask 100 can be reduced, making it more slender as a whole.

[0091] Please refer to Figure 1 and Figure 2, in some embodiments, the outer contour of the backlight layer 12 is larger than the outer contour of the light-emitting layer 11, and the first surface 10a is flush with the third surface 10c when the light-emitting layer 11 is placed in the groove 10d.

[0092] It can be understood that the outer contour of the backlight layer 12 being larger than the outer contour of the light-emitting layer 11 means that in the projection direction perpendicular to the first surface 10a or the second surface 10b, the projection of the light-emitting layer 11 is located within the projection of the backlight layer 12. Furthermore, from the perspective of the external structure, the backlight layer 12 is "one circle larger" than the light-emitting layer 11. In this way, when the two are stacked, the outermost periphery of the flexible light therapy mask 100 is the edge side of the backlight layer 12. Then, when the light-emitting layer 11 is placed in the groove 10d, the first surface 10a being flush with the third surface 10c can make the connection between the light-emitting layer 11 and the backlight layer 12 have a smooth transition, so as to reduce or alleviate the discomfort caused by the inconsistent end faces of the two.

[0093] In summary, when the user wears the flexible light therapy mask 100, the third surface 10c is also the end face facing the user's skin. Therefore, setting the third surface 10c flush with the first surface 10a can make a smooth transition between the outer edge of the light-emitting layer 11 and the groove wall of the groove 10d, so as to reduce the discomfort brought to the user during the wearing process of the flexible light therapy mask 100.

[0094] In some embodiments, the light-emitting layer 11 is more flexible than the backlight layer 12.

[0095] It can be understood that here, the entire backlight layer 12 is relatively more difficult to deform than the light-emitting layer 11. Then, the entire backlight layer 12 is used to support the light-emitting layer 11.

[0096] Please refer to Figure 4 , in some embodiments, the light-emitting part 20 includes a flexible circuit board 21, lamp beads 22 provided on the flexible circuit board 21, and a connection interface 23 electrically connected to the flexible circuit board 21. The flexible circuit board 21 is provided in the main body part 10, the lamp beads 22 face the first surface 10a, and the connection interface 23 is electrically connected to the flexible circuit board 21.

[0097] It can be understood that the flexible circuit board 21 has a certain deformability and is easy to deform accordingly with the main body part 10 to meet the need of fitting with the user's face. At the same time, the flexible circuit board 21 controls the circuit of the lamp beads 22, so that each lamp bead 22 emits light beams of the same or different bands.

[0098] Here, the number of the lamp beads 22 can be multiple. Each lamp bead 22 can emit light independently or synchronously, and the bands of the light beams emitted by each lamp bead 22 can be the same or different.

[0099] The connection interface 23 is used for electrically connecting with an external power supply to supply power to the flexible circuit board 21.

[0100] Please refer to Figure 6 , in some embodiments, a plurality of strip-shaped notches 24 are formed inwardly on the edge side of the flexible circuit board 21.

[0101] It can be understood that by forming a plurality of strip-shaped notches 24 on the edge side of the flexible circuit board 21, the probability of wrinkles occurring when the flexible circuit board changes from a planar state to a three-dimensional state can be reduced, and the installation stability of the flexible circuit board can be improved.

[0102] Exemplarily, three strip-shaped notches 24 are opened at the forehead of the flexible circuit board 21 corresponding to the user's face, and two strip-shaped notches 24 are opened at the cheeks of the flexible circuit board 21 corresponding to the user's face, both of which can reduce the probability of wrinkles occurring when the flexible circuit board 21 changes from a planar state to a three-dimensional state.

[0103] It should be noted that when the flexible circuit board 21 is installed on the main body 10, each strip-shaped notch 24 is closed due to the flexible circuit board 21 forming a three-dimensional structure. However, when the flexible circuit board 21 is in a planar state, the strip-shaped notch 24 returns to its initial state again.

[0104] 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.
