A helmet

Abstract

The technical scheme provides a helmet, which comprises an outer shell, an inner shell and a light processing assembly arranged between the outer shell and the inner shell, and the light processing assembly is composed of a laser layer and a light homogenization layer. Traditional laser helmets have problems of uneven irradiation and low light energy utilization rate because they directly irradiate the scalp with discrete light source points. The scheme emits treatment laser through the laser layer and homogenizes the laser beam through the light homogenization layer, so that the originally discrete light source is converted into a uniformly distributed surface light source. This design effectively eliminates the problems of light spot overlap or gap in the traditional irradiation mode, so that the laser energy uniformly covers the scalp and ensures that the light energy fully acts on the scalp skin. The scheme has a significant effect on improving treatment uniformity and light energy utilization rate.

Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, and in particular to a helmet. Background Technology

[0002] A laser therapy helmet is a medical device that uses low-intensity laser light (such as red or near-infrared light around 650nm) to irradiate the scalp, stimulating hair follicle activity and improving local microcirculation, thereby assisting in the treatment of hair loss or promoting hair growth. Traditional laser therapy helmets typically use an array of laser diodes (LDs) or light-emitting diodes (LEDs) to directly irradiate the scalp surface through multiple discrete light source points.

[0003] However, existing laser therapy helmets have the following main drawbacks:

[0004] Uneven laser irradiation: Because the laser layer uses multiple independent light source points arranged in a pattern, there is overlap or gap between the irradiation areas of each light source point, resulting in uneven laser irradiation distribution in different areas of the scalp. Some areas may be over-irradiated due to the dense concentration of light source points, while other areas may be under-irradiated due to the sparse or misaligned light source points, affecting the consistency of treatment results.

[0005] The aforementioned technical issues need to be addressed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes a helmet to solve the problem of uneven laser irradiation in existing physiotherapy laser helmets.

[0007] Firstly, the present technical solution provides a helmet comprising an outer shell and an inner shell, wherein the outer shell and the inner shell enclose an assembly space, and a light processing component is assembled in the assembly space, the light processing component comprising:

[0008] A laser layer is disposed in the assembly space and is electrically connected to the power module for emitting laser light when powered on.

[0009] A light homogenization layer is disposed in the laser irradiation direction of the laser layer and is used to uniformly irradiate the scalp with the laser emitted by the laser layer.

[0010] Furthermore, the light homogenization layer has a sheet-like structure that can conform to the curvature of the inner surface of the outer shell.

[0011] Furthermore, the shape of the light homogenization layer is adapted to the shape of the laser layer.

[0012] Furthermore, the outer surface of the light homogenization layer is in contact with the inner surface of the laser layer.

[0013] Furthermore, the power module includes a control board and a sound-generating element electrically connected to the control board;

[0014] The housing is provided with a sound passage hole, which is located directly above the sound-generating component.

[0015] Furthermore, the inner shell is a hollow annular structure and the annular portion has a thickness.

[0016] Furthermore, the inner shell includes at least two sub-inner and outer shells;

[0017] The outer shell includes at least two sub-outer shells;

[0018] Each of the inner sub-shells corresponds to one outer sub-shell assembly to form a laser irradiation unit;

[0019] Furthermore, the two adjacent laser irradiation units are folded and connected by a connector.

[0020] Furthermore, the sidewall of the laser irradiation unit has mounting holes for assembling the connector.

[0021] Furthermore, the connector includes a first part and a second part hinged to the first part;

[0022] A folding groove is formed at the connection between the first part and the second part;

[0023] The longitudinal section of the folded groove is V-shaped or U-shaped.

[0024] Furthermore, the first part or the second part is provided with a first embedding part and a second embedding part in sequence along the thickness direction;

[0025] The first embedding part and the second embedding part are respectively used for the end of the laser layer and the light homogenization layer to be inserted and connected.

[0026] The technical solutions provided in this application have the following advantages compared with the prior art:

[0027] This technical solution provides a helmet, including an outer shell, an inner shell, and a light processing component disposed between the two. This component comprises a laser layer and a light homogenization layer. Traditional laser helmets suffer from uneven irradiation and low light energy utilization due to the use of discrete light source points directly irradiating the scalp. This solution emits therapeutic laser through the laser layer and uses the light homogenization layer to homogenize the laser beam, transforming the originally discrete light source into a uniformly distributed area light source. This design effectively eliminates the problems of overlapping or gaps in traditional irradiation methods, ensuring that laser energy uniformly covers the scalp and that the light energy fully acts on the scalp skin. This solution has significant effects in improving treatment uniformity and light energy utilization. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] This invention proposes a helmet to solve the problem of uneven laser irradiation in existing therapeutic laser helmets. The helmet is suitable for applications such as promoting hair follicle activity or scalp care.

[0041] Detailed, such as Figure 1 The diagram shown illustrates the structure of a portion of the helmet. Figure 2 The exploded schematic diagram shows a helmet according to this technical solution, including an outer shell 1 and an inner shell 2. The outer shell 1 and the inner shell 2 enclose an assembly space 3. A light processing component 4 is assembled in the assembly space 3. The light processing component 4 includes: a laser layer 41, which is disposed in the assembly space 3. The laser layer 41 is electrically connected to a power module 5 and can emit laser after receiving electrical energy from the power module 5; and a light homogenization layer 42, which is disposed in the laser irradiation direction of the laser layer 41 and is used to uniformly irradiate the scalp with the laser emitted by the laser layer.

[0042] It should be noted that the shapes of the outer shell 1 and the inner shell 2 are adapted to the shape of the human head so that the helmet can be worn on the head.

[0043] The laser layer 41 and the light homogenization layer 42 are sheet-like structures made of flexible or rigid materials. This ensures that the helmet fits snugly against the head when worn, improving the uniformity of light irradiation and wearing comfort.

[0044] If a rigid material is used, the laser layer 41 can conform to the curvature of the inner surface of the outer shell 1. The shape of the light homogenization layer 42 is adapted to the shape of the laser layer 41. This ensures that the helmet fits snugly against the head when worn, improving the uniformity of light irradiation and wearing comfort. Flexible materials can naturally conform to the curve of the head, while the design of rigid materials needs to precisely match the head shape to optimize the phototherapy effect.

[0045] The power module 5 includes a control board 51 and a switch 52 and an electrical connector 53 electrically connected to it. The switch 52 is a touch button located on the housing 1. The electrical connector 53 is a Type-C interface used to connect to an external power supply to input external power into the power module 5, which can then supply power to the laser layer 41 after receiving the power.

[0046] In use, the helmet, whose shape conforms to the human head, is worn on the head. The user can touch the switch 52 to drive the power module 5. After receiving electrical energy, the laser layer 41 excites the electrons distributed within it to move, thereby generating light energy, i.e., a laser light source. However, due to the influence of the manufacturing process of the laser layer 41, these laser layers 41 usually contain impurities, causing uneven electron distribution density, thus producing several point-like discrete laser spots. However, by placing the light homogenizing layer 42 in the light source irradiation direction of the laser layer 41, the several point-like discrete laser spots can be scattered or refracted, transforming the point-like laser spots into a uniformly distributed surface light source. This design can improve the uniformity of laser irradiation coverage, avoid local energy overload, and effectively eliminate the problem of uneven illumination in traditional laser hair growth or scalp treatment devices. This technical solution ensures that laser energy uniformly covers the scalp, ensuring that the light energy fully acts on the scalp skin.

[0047] It should also be noted that the helmet in this technical solution can save energy after using a light homogenizing sheet.

[0048] In detail, existing laser helmets typically require adjusting the laser parameters to a power of 100 milliwatts at a wavelength of 650nm-660nm to ensure effective laser hair generation. However, by adding a homogenizer, the laser parameters can be set to between 4.5 and 5.5 milliwatts at a wavelength of 650nm-660nm. This allows for the use of fewer laser lamps or laser layers with lower electron density, while achieving a more uniform and wider irradiation area, thus saving on production material costs and energy.

[0049] In one embodiment of the present invention, the outer surface of the light homogenization layer 42 is in contact with the inner surface of the laser layer 41.

[0050] This design primarily addresses the issues of low optical transmission efficiency and high energy loss in laser therapy equipment. By physically bonding components to eliminate air gaps, it reduces scattering and reflection losses during laser transmission, enabling the laser to be transmitted to the light homogenization layer 42 more efficiently. Simultaneously, it ensures that the light homogenization layer 42 can completely receive and uniformly process the entire laser beam. This technology significantly improves optical energy transmission efficiency, reduces energy waste, and guarantees the integrity and uniformity of light homogenization. It also results in a more stable laser spot distribution and improved consistency of treatment effects.

[0051] To address the issue of insufficient light path propagation distance leading to poor illumination during laser treatment. For example... Figure 3 As shown, the inner shell 2 is a hollow annular structure with a thickness H. The hollow annular structure allows for a certain distance between the light homogenization layer 42 and the scalp, a distance that can range from one millimeter to five millimeters, and can be preset according to actual usage needs.

[0052] This design creates ample space for laser propagation within the housing, allowing the light emitted from laser layer 41 to diffuse sufficiently and maintain a suitable propagation distance. The annular thickness design ensures structural strength while providing an optimized physical channel for light propagation. During use, this ensures that the laser can fully expand and homogenize before reaching the scalp, avoiding excessive energy concentration and allowing for more even coverage of the treatment area. In addition, the hollow structure reduces overall weight and improves wearing comfort.

[0053] In one embodiment of this utility model, such as Figure 2 As shown, the power module 5 includes a sound-emitting element 54, such as a speaker. The sound-emitting element 54 is electrically connected to the control board 51. The outer casing 1 has a sound passage hole A, which is located directly above the sound-emitting element 54.

[0054] The power module 5 is pre-programmed with a broadcasting program, such as broadcasting "light therapy started - remaining light therapy time - light therapy ended" during phototherapy. In use, the control board 51 in the power module 5 transmits the broadcasting information to the sound-emitting element 54 according to the current usage status. The sound-emitting element 54 then emits broadcasting information matching the current usage status based on the received information, and transmits it to the outside through the sound hole A.

[0055] Furthermore, in one embodiment, such as Figure 4As shown, the outer shell 1 includes at least two sub-outer shells 11; the inner shell 2 includes at least two sub-inner and outer shells 21; each sub-inner shell 21 is assembled with one sub-outer shell 11 to form a laser irradiation unit 6. Specifically, each laser irradiation unit 6 includes the aforementioned light processing component 4 and a power module 6, enabling each laser irradiation unit 6 to operate independently. This allows for more flexible use to meet the user's needs; that is, wherever laser treatment is needed on the user's head, the corresponding laser irradiation unit 6 can be activated simply by using the switch 52.

[0056] In addition, two adjacent laser irradiation units 6 are folded and movably connected by a connector 7. Specifically, the side wall of the laser irradiation unit 6 has an assembly hole 61 for assembling the connector 7.

[0057] In this embodiment, there are six laser irradiation units 6. However, in other application scenarios, there may be seven or eight laser irradiation units; the specific number can be set according to actual usage needs. During use, the helmet can be folded in half along a predetermined direction, for example... Figure 3 As indicated by the arrow, fold the helmet vertically or horizontally in the direction of the paper to save storage space and improve portability.

[0058] like Figure 4 As shown, the connector 7 includes a first part 71 and a second part 72 hinged to the first part 71; a folding groove 73 is formed at the connection between the first part 71 and the second part 72; the longitudinal section of the folding groove 73 is V-shaped or U-shaped.

[0059] In this embodiment, since the first part 71 and the second part 72 are respectively connected to the laser irradiation units 6 located on both sides of the connector 7, during use, the first part 71 and the second part 72, under the limitation of the mounting hole 61, can prevent the adjacent laser irradiation units 6 from moving laterally, so that the adjacent laser irradiation units 6 can only be folded along the geometric shape of the folding groove 73, avoiding misalignment.

[0060] In detail, in this embodiment, the longitudinal section of the folding groove 73 is V-shaped. During use, the V-shaped groove achieves directional bending through the sliding contact of the inclined surfaces on both sides. The specific geometry guides the stress distribution during folding, ensuring the stability of the rotation axis and the precise guidance of the folding action.

[0061] Furthermore, the first 71 or the second 72 is provided with a first embedding portion 711 and a second embedding portion 721 in sequence along the thickness direction; the first embedding portion 711 and the second embedding portion 721 are respectively used for the ends of the laser layer 41 and the light homogenization layer 42 to be inserted and connected.

[0062] This design utilizes a precision slot structure in the embedding section to insert the ends of the laser layer 41 and the light homogenization layer 42 into the first embedding section 711 and the second embedding section 721, respectively, achieving mechanical interlocking between the light processing component 4 and the connector 7. The embedded connection improves the overall structural integrity and enhances resistance to vibration and shock; it also facilitates the modular production and maintenance of the laser irradiation unit 6; this design is particularly suitable for wearable therapeutic devices that require frequent folding.

[0063] The connector 7 also has a through hole 74, through which a fastener, such as a screw, is used to connect with an external decorative part to enhance the aesthetics of the helmet.

[0064] In summary, this technical solution provides a helmet that effectively addresses the problems of uneven irradiation and low light energy utilization inherent in traditional laser helmets, which use discrete light sources to directly illuminate the scalp. This solution emits therapeutic lasers through a laser layer and utilizes a light homogenization layer to homogenize the laser beam, transforming the originally discrete light source into a uniformly distributed area light source. This design effectively eliminates the problems of overlapping or gaps in traditional irradiation methods, ensuring that laser energy uniformly covers the scalp and that the light energy fully acts on the scalp skin. This solution has significant effects on improving treatment uniformity and light energy utilization.
