Technical Field

[0001] The present invention relates to the technical field of physiotherapy supplies, and particularly to a flexible light board and a physiotherapy cap. Background Art

[0002] With the improvement of people's awareness of scalp health and hair loss prevention, red and blue light physiotherapy caps have been widely used in the fields of home physiotherapy, beauty care, and scalp rehabilitation. Red and blue light physiotherapy caps usually use red and blue light to non-invasively irradiate the scalp, so as to promote blood circulation, activate hair follicle cells, sterilize and anti-inflammatory, regulate sebum secretion, etc., so as to achieve the purpose of improving the scalp microcirculation environment, relieving hair loss, controlling oil, and repairing hair follicles.

[0003] Currently, most of the red and blue light physiotherapy caps on the market use flexible circuit boards as carriers for red and blue light beads. The red and blue light beads are arranged on the flexible circuit board, and then the flexible circuit board is laid on the inner side of the cap to form a cover-like structure.

[0004] However, since the flexible circuit board needs to be laid on the inner side of the cap body, it is necessary to make the flat flexible circuit board deform into a cover-like structure. For this, the flexible circuit boards on the market include a plurality of connected sheet-like structures, and most of the flexible circuit boards are irregular structures in the flat state. Then when the flexible circuit board is installed on the inner side of the cap body, it is necessary to place the flexible circuit board on the inner side of the cap body and splice it. This installation method is more troublesome, and it is also impossible to ensure the stability of the positions of the various sheet-like structures of the flexible circuit board. Summary of the Invention

[0025] Compared with the prior art, the flexible light board in the embodiment of the present invention has the following beneficial effects:

[0026] In the present invention, the flexible circuit board includes a central portion and a connecting portion, and a plurality of the connecting portions are evenly distributed along the circumference of the central portion, and the plurality of the connecting portions extend radially with the central portion as the center, that is, the flexible circuit board is a relatively regular structure in a two-dimensional plane structure, so it is convenient to layout the circuits on the flexible circuit board, and the circuit trends are simpler, which greatly reduces the difficulty of wiring; furthermore, since the flexible circuit board is a relatively regular structure, the circuits on the flexible circuit board are also simpler and regular, so the arrangement of the red and blue light beads is also simpler, so that the red and blue light beads are also easier to be evenly arranged on the central portion and the connecting portion of the flexible circuit board, making the production of the flexible light board simpler and more convenient, and the cost can also be reduced. Therefore, the flexible lamp board is arranged with a relatively regular flexible circuit board, so that the multiple red and blue light lamp beads can be arranged more evenly thereon. Moreover, the flexible circuit board with a regular planar structure can be more easily combined together to form a three-dimensional cover-like structure and adapted to be installed in a physiotherapy cap. After the flexible circuit board forms a three-dimensional structure, the uniformity of the arrangement of the multiple red and blue light lamp beads thereon can also be ensured, thereby ultimately achieving a better physiotherapy effect.

[0027] In addition, two adjacent connecting parts are mutually clamped together through the first clamping seam and the second clamping seam, so that the two adjacent connecting parts can be detachably connected together. Specifically, when the plurality of connecting parts are gathered and merged together to form a three-dimensional cover-like structure of the flexible circuit board, the two adjacent connecting parts are first clamped together, the first clamping seam on one of the connecting parts is clamped into the other connecting part, and the one connecting part is clamped into the second clamping seam of the other connecting part, and the first clamping seam and the second clamping seam are opposite to each other, so that the two adjacent connecting parts are clamped and They are snapped together to ensure the stability of the connection between the two adjacent connecting parts, and then the multiple connecting parts are snapped together in turn to form a stable three-dimensional cover-like structure. Then, when the flexible lamp board with a three-dimensional cover-like structure is installed in the physiotherapy cap, it can be fitted into the inner side of the physiotherapy cap. Compared with the existing flexible circuit boards, the flexible lamp board of the present invention does not need to be combined and spliced in the physiotherapy cap to form a three-dimensional cover-like structure. Therefore, the installation of the flexible lamp board is simpler and more convenient, and the stable structure of the flexible lamp board can also ensure the uniformity of the arrangement of the multiple red and blue light beads on the flexible lamp board.

[0037] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0038] In the description of the present invention, it should be understood that the term "including" used in the specification of the present invention means the presence of the described features, integers, steps, operations, components and / or assemblies, but does not exclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies and / or their groups. It should be understood that when we say a component is "connected" to another component, it can be directly connected to other components, or there may also be intermediate components. The term "and / or" used here includes all or any unit and all combinations of one or more related listed items.

[0039] The red and blue light therapy cap is a wearable device that combines red and blue light therapy technologies, mainly used for scalp care, hair health, and improvement of the head skin. The wavelength of red light is usually 630nm - 660nm. The function of the red light emitted by the therapy cap is that it can penetrate deeper into the skin, stimulate capillary dilation, enhance blood circulation in the scalp, provide more nutrients for hair follicles, and red light can also stimulate hair follicles in the dormant period, prolong the growth period of hair, thus playing a role in reducing hair loss and promoting new hair growth. Moreover, red light also has a mild anti-inflammatory and repair effect on the skin, helping to soothe scalp discomfort and repair damaged tissues. The wavelength of blue light is usually 455nm - 475nm. The function of the blue light emitted by the therapy cap is to reduce the activity of sebaceous glands, regulate scalp oil secretion, and also has a strong bactericidal effect, which can effectively fight bacteria causing scalp inflammation, folliculitis, or dandruff, improve the healthy environment of the scalp, and also help clean impurities blocking hair follicles, making the hair roots cleaner and healthier.

[0040] Then, the existing therapy caps include a flexible circuit board arranged inside the therapy cap and lamp beads arranged on the flexible circuit board. Since the flexible circuit board is a two-dimensional planar structure during production, in order to fit the flexible circuit board on the inner side of the therapy cap, the flexible circuit board will be cut into complex and irregular shapes so that the flexible circuit board can be combined into a three-dimensional hemispherical cover shape, thereby enabling the installation of the flexible circuit board on the inner side of the therapy cap.

[0041] Since the existing flexible circuit board is in an irregular state in the two-dimensional planar structure, the circuits on the flexible circuit board will be more complex, making the wiring work more difficult, and causing uneven energy consumption distribution on the flexible circuit board, resulting in local overheating, affecting the service life of the flexible circuit board. Moreover, if the uniformity of the arrangement of lamp beads on the flexible circuit board needs to be considered, it will further increase the wiring difficulty on the flexible circuit board. Furthermore, even if the lamp beads are evenly arranged on the irregular flexible circuit board in the two-dimensional planar structure, when the flexible circuit board is bent and combined to form a three-dimensional hemispherical cover structure, it is easy to cause uneven distribution of lamp beads, resulting in uneven illumination intensity of the red and blue light of the therapy cap. Some areas are over-irradiated due to dense lamp beads, which may cause side effects such as skin redness and overheating, while other areas have insufficient illumination due to sparse lamp beads, resulting in ineffective stimulation of hair follicles or sterilization, ultimately affecting the overall therapy effect of the therapy cap.

[0042] Based on this, as Figures 1 to 3As shown in the figure, the present invention provides a flexible light board, which includes a flexible circuit board 1 and red and blue light beads 2. The flexible circuit board 1 includes a central portion 11 and connecting portions 12. There are multiple connecting portions 12, and the multiple connecting portions 12 are evenly distributed along the circumferential direction of the central portion 11. The multiple connecting portions 12 extend radially with the central portion 11 as the center. On one side of the connecting portion 12 adjacent to the central portion 11, there is an extension portion 14. The extension portion 14 is at the end far from the central portion 11. On the side of the extension portion 14 close to the central portion 11, a first clamping slot 141 is opened, and the first clamping slot 141 extends in the direction away from the central portion 11. In the area on the other side of the connecting portion 12 adjacent to the central portion 11, a second clamping slot 121 is opened, and the second clamping slot 121 is at the end far from the central portion 11. The second clamping slot 121 extends in the direction close to the central portion 11. Two adjacent connecting portions 12 are clamped to each other through the first clamping slot (141) and the second clamping slot (121), so that two adjacent connecting portions 12 are detachably connected together. A plurality of the red and blue light beads 2 are evenly arranged on the central portion 11 and the connecting portions 12.

[0043] In the present invention, the flexible circuit board 1 includes a central portion 11 and connecting portions 12. The multiple connecting portions 12 are evenly distributed along the circumferential direction of the central portion 11, and the multiple connecting portions 12 extend radially with the central portion 11 as the center. That is to say, when the flexible circuit board 1 is in a two-dimensional planar structure, it is a relatively regular structure. Then, it is convenient to layout the circuits on the flexible circuit board 1, and the circuit trend is simpler, greatly reducing the difficulty of wiring work. Moreover, since the flexible circuit board 1 is a relatively regular structure, the circuits on the flexible circuit board 1 are also simpler and more regular. Therefore, the arrangement of the red and blue light beads 2 is also simpler, and it is easier to evenly arrange the red and blue light beads 2 on the central portion 11 and the connecting portions 12 of the flexible circuit board 1, making the production of the flexible light board simpler and more convenient, and the cost can also be reduced. Therefore, by setting the relatively regular flexible circuit board 1, the flexible light board is convenient to arrange the multiple red and blue light beads 2 more evenly thereon. Moreover, the flexible circuit board 1 with a regular planar structure can also be more easily combined together to form a three-dimensional cover-shaped structure and be adaptively installed in the physiotherapy cap. And after the flexible circuit board 1 forms a three-dimensional structure, it can also ensure the uniformity of the arrangement of the multiple red and blue light beads 2 thereon, and finally can have a better physiotherapy effect.

[0044] In addition, two adjacent connecting parts 12 are mutually clamped together through the first clamping seam 141 and the second clamping seam 121, so that the two adjacent connecting parts 12 can be detachably connected together. Specifically, when the plurality of connecting parts 12 are gathered and merged together to form the flexible circuit board 1 into a three-dimensional cover-like structure, the two adjacent connecting parts 12 are first clamped together, so that the first clamping seam 141 on one of the connecting parts 12 is clamped into the other connecting part 12, and one of the connecting parts 12 is clamped into the second clamping seam 121 of the other connecting part 12, and the first clamping seam 141 and the second clamping seam 121 are opposite to each other, so that the flexible circuit board 1 can be clamped into the second clamping seam 121 of the other connecting part 12. Allow two adjacent connecting parts 12 to be snapped and buckled together to ensure the stability of the snapping of the two adjacent connecting parts 12. Then, snap the multiple connecting parts 12 together in turn to form a stable three-dimensional cover-like structure. Then, when the flexible lamp board with a three-dimensional cover-like structure is installed in the physiotherapy cap, it can be fitted into the inner side of the physiotherapy cap. Compared with the existing flexible circuit boards, the flexible lamp board of the present invention does not need to be combined and spliced in the physiotherapy cap to form a three-dimensional cover-like structure. Therefore, the installation of the flexible lamp board can be simpler and more convenient. In addition, the stable structure of the flexible lamp board can also ensure the uniformity of the arrangement of the multiple red and blue light beads 2 on the flexible lamp board.

[0045] Preferably, a first arcuate groove 142 is provided on one side of the extension portion 14 close to the central portion 11, and the first arcuate groove 142 is located at one end of the first slot 141 close to the central portion 11, so that the first arcuate groove 142 can play a positioning role, making it easier for the connecting portion 12 to be better inserted into the first slot 141, making it easier to fold and merge multiple connecting portions 12.

[0046] Furthermore, a second arc groove 122 is provided on a side of the connecting portion 12 away from the central portion 11, and the second arc groove 122 is located at an end of the second slot 121 away from the central portion 11, so that the second arc groove 122 can play a positioning role, making it easier for the connecting portion 12 to be better inserted into the second slot 121, making it easier to fold and merge multiple connecting portions 12.

[0047] In this embodiment, there is a gap 13 between two adjacent connecting portions 12, and an overlapping portion 16 is provided on at least one of the two sides of the connecting portion 12 adjacent to the central portion 11, and the overlapping portion 16 is located in the gap 13, and the overlapping portion 16 extends from one end of the connecting portion 12 close to the central portion 11 in a direction away from the central portion 11 to the middle area of the connecting portion 12, and each gap 13 on the flexible circuit board 1 is provided with the overlapping portion 16, and the width of the gap 13 gradually increases in the direction from the overlapping portion 16 to the extending portion 14.

[0048] Specifically, there is a gap 13 between two adjacent ones of the connecting portions 12. The overlapping portions 16 are provided on both sides of the connecting portion 12 adjacent to the central portion 11, and the overlapping portions 16 are located within the gap 13. Thus, when the flexible circuit board 1 is folded and combined to form a three-dimensional cover-like structure, the two adjacent overlapping portions 16 can overlap with each other, which is beneficial for making multiple connecting portions 12 more compact and not loose, is beneficial for improving the stability of the structure of the flexible light board, and can also play a role in blocking the gap 13 to improve the aesthetics. Then, since the extending portion 14 is at one end of the connecting portion 12 away from the central portion 11, in order to form enough space in the gap 13 to accommodate the extending portion 14, the width of the gap 13 gradually increases in the direction from the overlapping portion 16 to the extending portion 14. Therefore, when multiple connecting portions 12 are folded and combined together, an overlapping part is formed between two adjacent connecting portions 12 and in the area close to the central portion 11 through the overlapping portion 16, and an overlapping part is formed between two adjacent connecting portions 12 and in the area away from the central portion 11 through the extending portion 14. Thus, after the flexible circuit board 1 forms a stable three-dimensional cover-like structure, the stability and reliability of the structure of the flexible light board can be ensured, which is convenient for subsequent installation.

[0049] In this embodiment, a first round hole 123 and a second round hole 124 are formed in the connecting portion 12. The first round hole 123 is located at one end of the first slot 141 away from the central portion 11, and the first round hole 123 communicates with the first slot 141; that is, the first round hole 123 is provided at one end of the first slot 141 away from the central portion 11, thereby avoiding the problem of stress concentration at one end of the first slot 141 away from the central portion 11, making it not easy for the first slot 141 to tear in the direction away from the central portion 11, and also ensuring the firmness of the connection between multiple connecting portions 12.

[0050] Similarly, the second round hole 124 is located at one end of the second slot 121 close to the central portion 11, and the second round hole 124 communicates with the second slot 121; that is, the second round hole 124 is provided at one end of the second slot 121 close to the central portion 11, thereby avoiding the problem of stress concentration at one end of the second slot 121 close to the central portion 11, making it not easy for the second slot 121 to tear in the direction close to the central portion 11, and ultimately also ensuring the firmness of the connection between multiple connecting portions 12.

[0051] Furthermore, after two adjacent ones of the connecting portions 12 are clamped to each other through the first clamping slot 141 and the second clamping slot 121, the first round hole 123 and the second round hole 124 can overlap with each other, so as to play a certain buckling role, making it difficult for the connecting portion 12 to slide out of the first clamping slot 141 and the second clamping slot 121, so that two adjacent ones of the connecting portions 12 can be stably clamped together, and finally ensuring that a plurality of the connecting portions 12 are stably folded and combined together, so that the flexible light board forms a stable three-dimensional cover-shaped structure.

[0052] In this embodiment, the central portion 11 and the connecting portion 12 are integrally formed. On the one hand, this enables the central portion 11 and a plurality of the connecting portions 12 to be stably connected together, improving the overall structural reliability of the flexible light board; on the other hand, the flexible circuit board 1 can be directly cut to form the central portion 11 and the connecting portion 12, without subsequent splicing, making the production easier and more convenient.

[0053] In this embodiment, a third round hole 15 is formed in the flexible circuit board 1. The third round hole 15 is located at the junction of the central portion 11 and two adjacent ones of the connecting portions 12, and the third round hole 15 communicates with the gap 13.

[0054] Since the flexible circuit board 1 is formed with the central portion 11 and a plurality of the connecting portions 12 evenly distributed along the circumference of the central portion 11 by cutting during production, the stress is relatively concentrated at the junction between the central portion 11 and two adjacent ones of the connecting portions 12, and it is easy to tear at the junction under the action of an external force. To this end, by forming the third round hole 15 in the flexible circuit board 1, the third round hole 15 is located between the central portion 11 and two adjacent ones of the connecting portions 12, and the third round hole 15 communicates with the gap 13, so that the stress at the intersection between the central portion 11 and two adjacent ones of the connecting portions 12 can be eliminated. Therefore, it is not easy for the intersection between the central portion 11 and two adjacent ones of the connecting portions 12 to tear, ensuring the structural reliability of the flexible light board.

[0055] In this embodiment, the flexible circuit board 1 has an elliptical structure. The major axis of the elliptical structure has a dimension of 263.2 mm, and the minor axis of the elliptical structure has a dimension of 249.9 mm.

[0056] Since the human head is generally oval in shape, when the flexible circuit board 1 is in a two-dimensional planar structure, the flexible circuit board 1 is in an oval structure. Then, when the flexible circuit board 1 is folded and combined into a three-dimensional structure, an oval cover structure can be formed to better fit the shape of the user's head and ensure a better physical therapy effect on the head. In addition, when the flexible circuit board 1 is in a two-dimensional oval structure, the dimension of the major axis of the oval structure is maintained at 263.2 mm, and the dimension of the minor axis of the oval structure is maintained at 249.9 mm to adapt to the head sizes of most people, with high practicability.

[0057] In this embodiment, a deformation groove 125 is formed at one end of the connecting portion 12 away from the central portion 11, and the deformation groove 125 extends in a direction close to the central portion 11.

[0058] Since a plurality of the connecting portions 12 are circumferentially and uniformly arranged around the central portion 11, and the plurality of connecting portions 12 extend radially with the central portion 11 as the center, in order to enable the plurality of connecting portions 12 to cooperate with the central portion 11 to form an oval cover structure after being folded and combined, the width between two adjacent sides of the connecting portion 12 and the central portion 11 gradually increases in a direction away from the central portion 11. Eventually, the width of the side of the connecting portion 12 away from the central portion 11 is relatively large. Therefore, when the plurality of connecting portions 12 are folded and combined together, the sides of the plurality of connecting portions 12 away from the central portion 11 are connected into one body, making the lower edge of the flexible light board formed into a three-dimensional oval cover more taut, which easily causes two adjacent connecting portions 12 to become disengaged, and there are also certain difficulties in subsequently installing the flexible light board in the physical therapy cap. Therefore, by forming a deformation groove 125 at one end of the connecting portion 12 away from the central portion 11, and the deformation groove 125 extends a certain distance in a direction close to the central portion 11, so that the lower edge of the flexible light board has a certain amount of deformation, to prevent the lower edge of the flexible light board from being too taut and keep the plurality of connecting portions 12 stably connected together, and it is also convenient to install the flexible light board in the physical therapy cap later.

[0059] Specifically, the deformation groove 125 can be provided on each of the plurality of connecting portions 12, or the deformation groove 125 can be provided on some of the connecting portions 12 as needed.

[0060] Preferably, a fourth round hole 126 is further formed on the connecting portion 12, and the fourth round hole 126 is located at one end of the deformation groove 125 close to the central portion 11, and the fourth round hole 126 communicates with the deformation groove 125, thereby preventing stress concentration at one end of the deformation groove 125 close to the central portion 11 and making it not easy for one end of the deformation groove 125 close to the central portion 11 to be torn.

[0061] Combined with Figures 4 to 8 As shown, the present invention also relates to a physiotherapy cap, which includes a housing 3, a transparent inner housing 4 and the flexible light board. The housing 3, the transparent inner housing 4 and the flexible light board are all in an oval cover shape. The housing 3 covers the outside of the transparent inner housing 4, and the flexible light board is located between the housing 3 and the transparent inner housing 4.

[0062] In the physiotherapy cap of the present invention, by providing the opaque housing 3 and the light-transmitting transparent inner housing 4, the transparent inner housing 4 is adaptively installed in the housing 3, and then the flexible light board is adaptively located between the housing 3 and the transparent inner housing 4. At the same time, because the multiple red and blue light beads 2 on the flexible light board are evenly arranged on the flexible circuit board 1, when the user wears the physiotherapy cap, the red light and blue light of the red and blue light beads 2 of the flexible light board can pass through the transparent inner housing 4 and evenly irradiate on the user's head, which can achieve a better physiotherapy effect on the user's head skin. Specifically, through the irradiation of red light, the red light can penetrate deeper into the skin, stimulate the dilation of capillaries, enhance the blood circulation of the scalp, provide more nutrients for hair follicles, and the red light can also stimulate the hair follicles in the dormant period and extend the growth period of hair, so as to reduce hair loss and promote the growth of new hair. Moreover, red light also has a mild anti-inflammatory and repair effect on the skin, which helps to soothe scalp discomfort and repair damaged tissues. Through the irradiation of blue light, it can reduce the activity of sebaceous glands, regulate the scalp oil secretion, and also has a strong bactericidal effect, which can effectively fight against the bacteria causing scalp inflammation, folliculitis or dandruff, improve the healthy environment of the scalp, and also help to clean the impurities blocking the hair follicles, making the hair roots cleaner and healthier.

[0063] In this embodiment, a positioning step 41 is provided along the circumferential direction of the transparent inner housing 4 in the area near the lower edge of the transparent inner housing 4, and the lower edge of the flexible light board abuts against the positioning step 41.

[0064] When assembling the housing 3, the transparent inner housing 4 and the flexible light board of the physiotherapy cap, by providing the positioning step 41 in the area near the lower edge of the transparent inner housing 4, the three-dimensional oval-shaped flexible light board can be sleeved outside the transparent inner housing 4, and the lower edge of the flexible light board abuts against the positioning step 41, so that the flexible light board can be pre-positioned on the transparent inner housing 4. Then, the transparent inner housing 4 and the flexible light board can be assembled together into the housing 3 to complete the assembly work of the physiotherapy cap. This assembly method is simpler and more convenient, and the flexible light board is pre-positioned first to ensure the accuracy of the position of the flexible light board after assembly, so as to ensure the physiotherapy effect when the physiotherapy cap is used.

[0065] Preferably, the physiotherapy cap further includes a tape. The flexible light board is disposed outside the transparent inner shell 4, and the flexible light board is fixed to the transparent inner shell 4 by the tape. One end of the tape is pasted between two adjacent connecting portions 12 of the flexible light board, covering the first slot 141 and the second slot 121, and the other end of the tape is pasted on the outside of the transparent inner shell 4.

[0066] When the flexible light board is disposed outside the transparent inner shell 4 and the lower edge of the flexible light board abuts against the positioning step 41 of the transparent inner shell 4 to pre-position the flexible light board, then it is convenient for the user to fix the flexible light board and the transparent inner shell 4 by the tape. Specifically, there are a plurality of tapes, and each tape is pasted between two adjacent connecting portions 12. One end of the tape is pasted between two adjacent connecting portions 12 of the flexible light board, covering the first slot 141 and the second slot 121, so that two adjacent connecting portions 12 can also be bonded together to ensure the reliability of the structure of the flexible light board. Then the other end of the tape is pasted on the outside of the transparent inner shell 4, so that the flexible light board is stably fixed and sleeved outside the transparent inner shell 4, further ensuring that the flexible light board will not shift during the use of the physiotherapy cap and ensuring the physiotherapy effect of the physiotherapy cap.

[0067] In this embodiment, the flexible light board further includes a power cord 5 and a pressing member 6. The housing 3 is provided with a through hole. One end of the power cord 5 is located between the housing 3 and the flexible light board and is electrically connected to the flexible circuit board 1 of the flexible light board. The other end of the power cord 5 passes through the through hole to the outside of the housing 3, and the pressing member 6 is disposed inside the housing 3 and presses the power cord 5 against the inside of the housing 3.

[0068] That is to say, after the power cord 5 is inserted into the housing 3 and electrically connected to the flexible circuit board 1, in order to prevent the power cord 5 from being disconnected from the flexible circuit board 1 easily when the power cord 5 is pulled under an external force, a pressing member 6 can be provided inside the housing 3 to press and fix the power cord 5 against the inside of the housing 3, so that the power cord 5 is not easily disconnected from the flexible circuit board 1 when being pulled, ensuring the reliability of the use of the physiotherapy cap.

[0069] Preferably, the pressing member 6 includes a pressing plate 61 and a fixing member 62. The pressing plate 61 is made of stainless steel to have sufficient structural strength. On the side of the pressing plate 61 facing the housing 3, a wire groove 63 is provided. The pressing plate 61 is fixed to the inner side of the housing 3 through the fixing member 62, and the power cord 5 passes through the wire groove 63.

[0070] Specifically, the fixing member 62 is a fixing rivet. Both ends of the pressing plate 61 are stably fixed to the inner side of the housing 3 through the fixing rivets, so that the pressing plate 61 is pressed against the inner side of the housing 3. A wire groove 63 is provided on the side of the pressing plate 61 facing the housing 3, and the wire groove 63 is located between the fixing rivets at both ends of the pressing plate 61. After the power cord 5 passes through the wire groove 63, the pressing plate 61 firmly presses the power cord 5 against the inner side of the housing 3, so that the power cord 5 is not easily disconnected from the flexible circuit board 1 due to external pulling force.

[0071] In this embodiment, the physiotherapy cap further includes a protective sleeve 7. The protective sleeve 7 penetrates through the through hole of the housing 3, and the power cord 5 penetrates through the protective sleeve 7.

[0072] That is to say, by providing the protective sleeve 7, the protective sleeve 7 is plugged into the through hole, and then one end of the protective sleeve 7 extends into the interior of the housing 3, and the other end of the protective sleeve 7 extends to the outside of the housing 3. The protective sleeve 7 can be made of rubber or silica gel. After the power cord 5 passes through the protective sleeve 7 and enters the interior of the housing 3, the protective sleeve 7 can protect the connection between the power cord 5 and the housing 3. After long-term use, the power cord 5 is not easily damaged.

[0073] In addition, by tightly wrapping the power cord 5 with the protective sleeve 7, the tensile strength of the power cord 5 is also improved, ensuring the reliability of the physiotherapy cap.

[0074] Preferably, a limiting ring 71 is provided on the outer periphery of one end of the protective sleeve 7 located inside the housing 3, and the limiting ring 71 abuts against the inner side of the housing 3.

[0075] That is to say, by providing the limiting ring 71 on the outer periphery of one end of the protective sleeve 7 entering the housing 3, and the outer diameter of the limiting ring 71 is greater than the inner diameter of the through hole of the housing 3, the limiting ring 71 can be tightly pressed against the inner side of the housing 3, thereby restricting the protective sleeve 7 from coming out of the through hole and ensuring the stability of the position of the protective sleeve 7, so as to ensure that the protective sleeve 7 can provide better protection for the power cord 5 during long-term use.

[0076] In this embodiment, the physiotherapy cap further includes a support gasket 8, and the support gasket 8 is disposed between the inner side of the limit ring 71 and the outer shell 3.

[0077] Specifically, the area of the support gasket 8 in contact with the inner side of the outer shell 3 is larger than the area of the limit ring 71 in contact with the support gasket 8. That is to say, the size of the support gasket 8 is larger than the size of the limit ring 71. Thus, by providing the support gasket 8, the contact area can be increased and the pressure can be reduced, so as to further enhance the stability of the connection between the protective sleeve 7 and the outer shell 3.

[0078] Preferably, a groove 31 is further provided on the inner side of the outer shell 3. The bottom of the groove 31 is a flat surface, and the through hole, the pressing plate 61 and the support gasket 8 are all located at the bottom of the groove 31.

[0079] That is to say, since the outer shell 3 is in an elliptical cover shape, it is difficult to stably install the support gasket 8 and the pressing plate 61 on the inner side of the outer shell 3. For this reason, the groove 31 is provided on the inner side of the outer shell 3, and the bottom of the groove 31 is a flat surface, so that the support gasket 8 and the pressing plate 61 can be stably placed in the groove 31, ensuring the overall reliability of the physiotherapy cap.

[0080] In this embodiment, the physiotherapy cap further includes a connecting sleeve 9 and a mounting member 10. The connecting sleeve 9 is used to be sleeved on the lower edges of the outer shell 3 and the transparent inner shell 4, and the two sides of the connecting sleeve 9 are correspondingly pressed against the outer side of the outer shell 3 and the inner side of the transparent inner shell 4. The mounting member 10 penetrates through the opposite sides of the outer shell 3, the transparent inner shell 4 and the connecting sleeve 9 to fix the connecting sleeve 9 on the lower edges of the outer shell 3 and the transparent inner shell 4.

[0081] Specifically, the mounting member 10 is a mounting rivet. After assembling the housing 3, the transparent inner housing 4, the flexible light board, the pressing member 6, the power cord 5, the protective sleeve 7, and the support gasket 8, the connecting sleeve 9 can be installed. By sleeving the connecting sleeve 9 on the lower edges of the housing 3 and the transparent inner housing 4, and making the two sides of the connecting sleeve 9 closely adhere to the outer side of the housing 3 and the inner side of the transparent inner housing 4 respectively, the connecting sleeve 9 can wrap the lower edges of the transparent inner housing 4 and the housing 3. Then, the mounting rivet penetrates through the opposite sides of the housing 3, the transparent inner housing 4, and the connecting sleeve 9 to firmly fix the connecting sleeve 9 on the lower edges of the housing 3 and the transparent inner housing 4, ensuring the stability of the installation of the connecting sleeve 9 and preventing it from being easily disassembled. Then, the connecting sleeve 9 is made of silicone or rubber. Thus, when the user wears the physiotherapy cap, under the protection of the connecting sleeve 9, the user's head is not easily scratched, and the comfort during wearing can be improved.

[0082] A plurality of the mounting rivets are evenly distributed along the circumferential direction of the lower edge of the housing 3 to ensure that the connecting sleeve 9 is firmly fixed on the lower edges of the housing 3 and the transparent inner housing 4.

[0083] The physiotherapy cap of the present invention can also be used in combination with other casual caps. For example, a peaked cap can be sleeved on the outside of the physiotherapy cap, which can play a role in hiding the physiotherapy cap, facilitating the user to use it outdoors and ensuring better aesthetics and higher practicality.

[0084] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
