[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] It should be noted that, in the description of this application, if the terms "first", "second", etc. appear, "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" appears in the full text, its meaning is that it includes three parallel solutions, taking "A and / or B as an example", including Solution A, or Solution B, or a solution that satisfies both A and B.

[0048] Please refer to Figure 1 The embodiment of the present application proposes a phototherapy helmet 100, which can be worn on the head and used for physical therapy of the head. For example, the phototherapy helmet 100 can be used for hair growth therapy by stimulating the scalp to help hair growth; or, the phototherapy helmet 100 can stimulate acupuncture points on the head to relieve fatigue.

[0049] Please refer to Figures 2 to 5 In the embodiment of the present application, the phototherapy helmet 100 includes a shell 10, a phototherapy lamp 20, a plurality of elastic protrusions 30, a plurality of plug-in parts 40 and other structures. The shell 10 is formed with an open accommodating cavity 121, and the shell 10 is also provided with a plurality of plug-in holes 122 that penetrate the cavity wall of the accommodating cavity 121. The phototherapy lamp 20 is fixed to the shell 10 and is used to emit light into the accommodating cavity 121. The elastic protrusion 30 protrudes from the cavity wall of the accommodating cavity 121, and the plurality of plug-in parts 40 are connected to the plurality of elastic protrusions 30 in a one-to-one correspondence, and the plug-in parts 40 are plugged and fixed to the plug-in holes 122.

[0050] The outer shell 10 is used as the wearing body of the helmet, and the accommodating cavity 121 formed by it is used as the wearing space. The user's head extends into the accommodating cavity 121, so that the outer shell 10 is worn on the head. Therefore, the shape of the accommodating cavity 121 imitates the shape of the human head, so that the outer shell 10 fits the head better. The outer shell 10 can be a single-layer or multi-layer structure, and there is no specific limitation.

[0051] The phototherapy lamp 20 can emit light of a specific wavelength, such as red light, infrared light, blue light, ultraviolet light, etc., and utilize the radiation energy of these lights to treat related diseases. For example, infrared rays act on the human body to improve local blood circulation, promote swelling reduction, relieve pain, reduce muscle tension, and relieve muscle spasms. Ultraviolet rays act on the human body to have anti-inflammatory, analgesic, and anti-rickets effects. In addition, low-intensity laser stimulation can also promote hair growth.

[0052] The elastic protrusion 30 refers to a component with a certain elasticity that can play a buffering role, including but not limited to silicone, rubber, sponge, etc. When the shell 10 is worn on the head, since the elastic protrusion 30 protrudes from the cavity wall of the accommodating cavity 121, the head will directly abut against the elastic protrusion 30. On the one hand, the elastic protrusion 30 is relatively soft, so it can play a certain protective role on the head and improve the wearing comfort; on the other hand, the elastic protrusion 30 can adapt to different shapes of heads by deformation; furthermore, at least at the position corresponding to the elastic protrusion 30, the scalp is spaced from the shell 10, and this part of the space is conducive to the flow of air, reducing the stuffiness when wearing, and can also improve the wearing comfort and improve the user experience.

[0053] Each elastic protrusion 30 is provided with a plug-in portion 40, and the plug-in portion 40 and the elastic protrusion 30 are fixed to each other to form a whole. The plug-in portion 40 passes through the plug-in hole 122 on the housing 10 to achieve fixation with the housing 10, so that the elastic protrusion 30 is fixed with the housing 10 through the plug-in portion 40. This plug-in method can not only achieve rapid fixation of the plug-in portion 40 and the housing 10, but also facilitate the positioning of the plug-in portion 40 and the housing 10, ensuring that the elastic protrusion 30 connected to the plug-in portion 40 can act on the corresponding position of the user.

[0054] Please refer to Figure 5 , Figure 7 and Fig. 9Furthermore, the elastic protrusion 30 has a positioning groove 321, the cavity wall of the accommodating cavity 121 is provided with a positioning protrusion 123 plugged into the positioning groove 321, the plug hole 122 penetrates the positioning protrusion 123, and the plug-in portion 40 is connected to the groove bottom of the positioning groove 321 and extends outwardly to protrude from the positioning groove 321. By plugging the positioning groove 321 of the elastic protrusion 30 with the positioning protrusion 123 on the shell 10, the elastic protrusion 30 can be positioned relative to the shell 10. Moreover, when the elastic protrusion 30 is sleeved on the positioning protrusion 123, the two are superimposed so that the elastic protrusion 30 has a larger protruding height on the cavity wall of the accommodating cavity 121, thereby forming a larger gap between the shell 10 and the scalp. Furthermore, the positioning protrusion 123 is equivalent to a skeleton structure that can form the elastic protrusion 30, providing a certain support for the elastic protrusion 30, and preventing the elastic protrusion 30 from being excessively tilted and bent when under pressure.

[0055] The positioning protrusion 123 can be adapted and plugged with the positioning groove 321 , that is, the positioning protrusion 123 completely fills the space of the positioning groove 321 ; or, the positioning protrusion 123 only adapts to the component space of the positioning groove 321 .

[0056] Please refer to Figure 6 and Figure 7 In some embodiments, the elastic protrusion 30 includes a buffer portion 31 and a sleeve portion 32. The buffer portion 31 is connected to one end of the sleeve portion 32 in the axial direction. The buffer portion 31 is in a bell-mouth shape on the side away from the sleeve portion 32. The sleeve portion 32 is in a cylindrical shape and its internal space forms a positioning groove 321. The bell-mouth-shaped buffer portion 31 can produce a large deformation, and when it is pressed and flattened, the contact area with the scalp is large, which can achieve better support, and the sleeve portion 32 can be conveniently directly sleeved on the positioning protrusion 123.

[0057] Please refer to Figure 3 In some embodiments, the housing 10 is a double-layer structure, and includes an outer shell 11 and an inner shell 12. The side of the inner shell 12 facing away from the outer shell 11 forms a receiving cavity 121, and the cavity wall of the receiving cavity 121 refers to the side of the inner shell 12 facing away from the outer shell 11. The outer shell 11 and the inner shell 12 can be fixed by screws, buckles, glue bonding or hot melt welding.

[0058] Furthermore, an installation space can be formed between the outer shell 11 and the inner shell 12, and the phototherapy lamp 20 is arranged in the installation space and is clamped and fixed by the outer shell 11 and the inner shell 12. The position of the inner shell 12 corresponding to the phototherapy lamp 20 is set to a light-transmitting material, and the light emitted by the phototherapy lamp 20 can pass through the light-transmitting material to reach the outside. In some implementations, the middle part of the inner shell 12 is set to a light-transmitting member such as glass or acrylic plate, and the edge part of the inner shell 12 surrounds the middle part and is set to a non-light-transmitting structure.

[0059] Of course, in other embodiments, the phototherapy lamp 20 may also be disposed outside the housing 10 , for example, directly exposed on the wall of the accommodating cavity 121 .

[0060] Please refer to it again Figure 5 and Fig. 9 When the housing 10 includes an inner shell 12 and an outer shell 11, the plug hole 122 penetrates the inner shell 12, and a part of the inner shell 12 is recessed into the accommodating cavity 121 so that a positioning protrusion 123 is formed on one side of the inner shell 12, and a recess 124 is formed on the other side opposite to the inner shell 11, and the plug-in portion 40 is bonded to the inner shell 12 at the recess 124. In this embodiment, the inner shell 12 can be made of metal, so the positioning protrusion 123 and the recess 124 are formed by integral stamping. Alternatively, the inner shell 12 is a plastic part, and the positioning protrusion 123 and the recess 124 are formed by integral injection molding. The formation of the recess 124 is similar to the formation of a glue-containing groove, which can not only accommodate more glue to improve the bonding stability between the plug-in portion 40 and the inner shell 12, but also prevent excess glue from overflowing from the inner shell 12. Furthermore, after the plug-in portion 40 passes through the plug-in hole 122 and is bonded to the inner shell body 12 by glue, the plug-in connection and the glue bonding work together to achieve a double fixing effect.

[0061] Please refer to it again Figure 5 and Figure 8 In order to better limit the position of the plug-in portion 40, the plug-in portion 40 further has a first limiting surface 41, which abuts against the side of the inner shell 12 away from the accommodating cavity 121, thereby limiting the plug-in portion 40 from being separated from the inner shell 12 along the axial direction of the plug hole 122 into the accommodating cavity 121. Optionally, the plug-in portion 40 is generally columnar, and the diameter of a part of the plug-in portion 40 can be set to be larger, so the first limiting surface 41 mentioned above can be formed at the connection between the larger and smaller diameters, and the first limiting surface 41 is similar to a step surface.

[0062] Furthermore, at least part of the plug-in portion 40 is provided with an annular groove 43, and two facing groove walls of the annular groove 43 respectively constitute a first limiting surface 41 and a second limiting surface 42, and the first limiting surface 41 and the second limiting surface 42 respectively abut against two opposite sides of the inner shell 12, thereby preventing the plug-in portion 40 from moving axially along the plug-in hole 122. Due to the provision of the second limiting surface 42, the buffer portion 31 and the positioning protrusion 123 can be spaced apart to form a gap between the two.

[0063] Please refer to Fig.10 The inner shell 12 has a middle region 125 and an edge region 126 arranged around the middle region 125. Fig.10In the figure, the middle area 125 and the edge area 126 are divided by circle O, the depth of the accommodating cavity 121 in the middle area 125 is greater than the depth of the accommodating cavity 121 in the edge area 126, the plurality of plug-in parts 40 include a first plug-in part 40a located in the middle area 125 and a second plug-in part 40b located in the edge area 126, and the second plug-in part 40b is provided with an annular groove 43. The side of the buffer part 31 of the elastic protrusion 30 in the middle area 125 facing the cavity wall of the installation cavity abuts against the positioning protrusion 123.

[0064] Since the middle area 125 is basically facing the top of the head, the buffer part 31 on the middle area 125 has its bell mouth facing the top of the head, and the force on the buffer part 31 is basically the same as its opening direction, so the buffer part 31 does not need to be bent, and can be directly abutted against the positioning protrusion 123.

[0065] The edge area 126 is gradually curved relative to the middle area 125. When wearing from top to bottom, the head will press the elastic protrusion 30 of the edge area 126 upward. Since there is a gap between the buffer part 31 and the positioning protrusion 123, this gap allows the buffer part 31 to undergo a larger bending deformation relative to the sleeve part 32, thereby reducing the wearing resistance.

[0066] Please refer again Figure 8 Furthermore, a portion of the peripheral surface of the plug-in portion 40 is provided as an inclined surface 44 so that the diameter of the plug-in portion 40 gradually decreases in the direction away from the elastic protrusion 30, and the inclined surface 44 is connected to the first limiting surface 41. When the plug-in portion 40 is inserted into the plug-in hole 122, the inclined surface 44 plays a guiding role, guiding the plug-in portion 40 to align with the plug-in hole 122 for plugging.

[0067] Please refer to it again Figure 6 and Figure 7 Furthermore, the phototherapy helmet 100 also includes an elastic pad 50, which is in contact with the cavity wall of the accommodating cavity 121, and the plug-in portion 40, the elastic protrusion 30 and the elastic pad 50 are integrally injection molded. Specifically, the plug-in portion 40 is connected to the elastic protrusion 30, and the elastic protrusion 30 is connected to the elastic pad 50. Through the form of integral injection molding, the plug-in portion 40, the elastic protrusion 30 and the elastic pad 50 form a whole, and the subsequent assembly process is omitted. In addition, each elastic protrusion 30 is connected to an elastic pad 50, and can be assembled as a whole to the outer shell 10 for easy overall positioning. Furthermore, the loss of individual smaller components can also be avoided.

[0068] In some embodiments, the elastic pad 50 includes a plurality of connecting belts 51 arranged in an alternating manner, each connecting belt 51 is respectively fitted with the cavity wall of the accommodating cavity 121, and a plurality of elastic protrusions 30 are provided on each connecting belt 51 and along the length direction. Specifically, the elastic pad 50 includes three longitudinal connecting belts 51 and one transverse connecting belt 51, the three longitudinal connecting belts 51 are sequentially spaced and distributed in the transverse direction, the transverse connecting belt 51 is arranged in the middle of the longitudinal connecting belt 51, and sequentially connects the three longitudinal connecting belts 51. Compared with a whole large pad, the elastic pad 50 is arranged in the form of a plurality of connecting belts 51, at least part of the positions between two adjacent connecting belts 51 are not connected and there is a gap, when the elastic pad 50 is fitted to the cavity wall of a curved shape, this part of the gap can provide space for deformation, so that the elastic pad 50 can better adapt to the shape of the cavity wall, so the fitting effect after installation is better, and bulging can be prevented.

[0069] Please refer to Fig.13 The phototherapy lamp 20 includes a flexible circuit board 21 and a plurality of light-emitting components (not shown) disposed on the flexible circuit board 21, wherein the light-emitting components are light-emitting diodes (LED lamps). The connecting belt 51 is disposed away from the light-emitting components to avoid blocking the light emitted by the light-emitting components. Of course, in other embodiments, the elastic protrusion 30, the plug-in portion 40 and the elastic pad 50 are all made of transparent materials, such as transparent silicone, so that light can pass through.

[0070] In some embodiments, the flexible circuit board 21 includes a plurality of flexible belts 211, and each flexible belt 211 is provided with a plurality of light-emitting parts. These flexible belts 211 can also be arranged in a criss-cross pattern and connected to form a whole, so as to facilitate overall assembly. Specifically, the flexible circuit board 21 includes a plurality of longitudinal flexible belts 211, a transverse flexible belt 211 and an annular flexible belt 211, and both ends of the longitudinal flexible belt 211 and both ends of the transverse flexible belt 211 are respectively connected to the inner wall of the annular flexible belt 211, and the transverse flexible belt 211 is arranged across the longitudinal flexible belt 211 and connects the plurality of longitudinal flexible belts 211 in sequence. The entire flexible circuit board 21 can be designed as an upward concave shape to facilitate adaptation and installation with the housing 10.

[0071] Please refer to Fig.11 and Fig.12 Furthermore, the outer shell 11 is provided with a plurality of limiting ribs 111, and the plurality of limiting ribs 111 form a plurality of limiting grooves 112, and each flexible belt 211 is arranged in a limiting groove 112, so that a certain limitation can be performed through the limiting groove 112 to ensure that the light-emitting part on the flexible belt 211 irradiates the corresponding acupuncture points on the head.

[0072] Furthermore, a support rib 113 is further provided in the limiting groove 112. The support rib 113 includes a support substrate 1131 and two limiting protrusions 1132. The support substrate 1131 is connected to the bottom wall of the limiting groove 112. The limiting protrusions 1132 are located on the side of the support substrate 1131 away from the bottom wall of the limiting groove 112. The two limiting protrusions 1132 are arranged at intervals. The flexible belt 211 is overlapped with the support substrate 1131 and is located between the two limiting protrusions 1132. Fig.13 As shown, limiting notches 212 are provided on both opposite sides of the flexible belt 211, and the limiting notches 212 are engaged with the limiting protrusions 1132. In this embodiment, after the supporting substrate 1131 supports the flexible belt 211, there is a gap between the flexible belt 211 and the bottom wall of the limiting groove 112, and this gap is beneficial to the heat dissipation of the flexible belt 211, thereby preventing the phototherapy lamp 20 from overheating. In addition, the supporting substrate 1131 and the inner shell 12 can work together to clamp the flexible belt 211 inside to prevent the flexible belt 211 from shifting. The cooperation between the limiting protrusion 1132 and the limiting notch 212 further prevents the flexible belt 211 from moving along the length and width directions of the limiting groove 112, thereby achieving a more accurate positioning effect.

[0073] When the plug-in portion 40 passes through the plug-in hole 122 on the inner shell 12 and reaches between the inner shell 12 and the outer shell 11, the end of the plug-in portion 40 can directly abut against the side of the flexible circuit board 21 facing the inner shell 12, or the plug-in portion 40 is staggered with the flexible circuit board 21.

[0074] Furthermore, the housing 10 is provided with a plurality of ventilation holes (not shown in the figure), which penetrate the inner shell 12 and the outer shell 11 and avoid the limit groove 112. Optionally, two ventilation holes are provided between each two adjacent longitudinal flexible belts 211, and the two ventilation holes are distributed on both sides of the width direction of the transverse flexible belt 211, and the ventilation holes extend along the length direction of the flexible belt 211 to form long strip holes. The transverse connecting belt 51 is provided corresponding to the transverse flexible belt 211, and the longitudinal connecting belt 51 is provided corresponding to the longitudinal flexible belt 211, and both avoid the above-mentioned ventilation holes. In this embodiment, the provision of the ventilation holes realizes the connection between the outside and the accommodating chamber 121, and airflow exchange can be realized between the two, so as to avoid the temperature in the accommodating chamber 121 being too high and stuffy, and ensure the coolness and ventilation in the accommodating chamber 121, thereby improving the user experience. Furthermore, with the provision of the elastic protrusion 30, the elastic protrusion 30 separates the scalp from the inner wall of the accommodating cavity 121, so that the external airflow can directly act on the scalp, which is more conducive to improving the comfort of most of the scalp or even the entire scalp.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
