Safety helmet with heat insulation function

Abstract

This utility model belongs to the field of safety helmet technology, specifically providing a safety helmet with heat insulation function. It includes a helmet body, a cooling fan, and a heat-reflecting unit. The inner wall of the helmet body is densely covered with multiple grooves, dividing the inner wall of the protective space into multiple spaced-apart raised units, which support the heat-reflecting unit. When the cooling fan operates, it generates airflow that blows away the hot air inside the protective space. The air inside the grooves and the heat-reflecting unit act as heat insulation media, reducing the amount of heat entering the protective space through the helmet body from the outside, thus solving the problem of the helmet body absorbing heat and causing stuffiness inside the protective space under direct sunlight. The cooling fan also blows away the heat emitted by the wearer, improving comfort in outdoor environments exposed to direct sunlight. The heat-reflecting unit is located on the inner wall of the protective space, making it less prone to scratches and coating peeling, and less susceptible to damage over long-term use.

Description

Technical Field

[0001] This application belongs to the field of safety helmet technology, and more specifically, relates to a safety helmet with heat insulation function. Background Technology

[0002] In construction engineering, safety helmets are essential protective equipment. While they protect the wearer's head, during outdoor work, direct sunlight causes the helmet to absorb heat from infrared rays, leading to a stuffy and uncomfortable feeling on the wearer's head. Furthermore, the wearer also dissipates heat while working, further increasing the internal temperature of the helmet. The combined effects of external sunlight and the wearer's own heat dissipation result in a very hot and stuffy interior, significantly reducing the helmet's comfort.

[0003] To reduce heat absorption on the surface of safety helmets, existing technologies, such as the technical document in Chinese Patent Publication No. CN214414239U entitled "A Safety Helmet for Power Construction," disclose a technical solution of setting a reflective heat-insulating coating on the outer shell of the safety helmet. The shortcomings of the above technical solution are: the coating is set on the outer surface of the shell, and because the coating thickness is relatively thin, it is prone to aging conditions such as scratches, friction, and coating peeling, leading to a deterioration in heat reflection effect. Utility Model Content

[0004] Based on the above-mentioned technical problems, this application provides a safety helmet with heat insulation function to solve the technical problem that the reflective heat insulation coating in the prior art is prone to aging such as scratches, friction, and coating peeling, which leads to a deterioration of the heat reflection effect.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a safety helmet with heat insulation function, comprising:

[0006] The helmet body has a protective space for accommodating the head. The inner wall of the protective space has multiple grooves, which divide the inner wall of the protective space into multiple protruding units arranged at intervals.

[0007] A cooling fan is disposed on the helmet body, and the airflow direction of the cooling fan is towards the protective space; and

[0008] A heat-reflective unit covers the surface of the raised unit.

[0009] In one possible implementation, the groove is formed in the area corresponding to the top of the wearer's head on the inner wall of the protective space, and the inner wall of the protective space is also provided with an annular dividing groove, which surrounds the periphery of the groove distribution area, and the edge of the heat reflective unit extends to the outside of the dividing groove.

[0010] In one possible implementation, the heat-reflecting unit includes:

[0011] A first heat-reflective layer covers the surface of the protruding unit;

[0012] A heat-insulating layer covers the side of the first heat-reflective layer opposite to the protruding unit; and

[0013] A second heat-reflective layer covers the side of the heat insulation layer that is away from the first heat-reflective layer.

[0014] In one possible implementation, the first heat-reflective layer is bonded to the protruding unit by adhesive.

[0015] In one possible implementation, the first heat-reflective layer and the second heat-reflective layer are both aluminum foil layers.

[0016] In one possible implementation, the heat-reflective unit is a heat-reflective coating applied to the surface of the protruding unit and the inner wall of the groove.

[0017] In one possible implementation, the grooves are arranged in a grid pattern.

[0018] In one possible implementation, the inner wall of the protective space is provided with multiple buckles spaced apart along the circumferential direction, and the heat-insulating safety helmet also includes an inner liner, which is engaged with the buckles.

[0019] In one possible implementation, the helmet body is integrally formed with a brim.

[0020] In one possible implementation, a solar panel is provided on the top of the helmet body, and the solar panel is electrically connected to the cooling fan.

[0021] Compared with existing technologies, the beneficial effects of the heat-insulating safety helmet provided in this application are:

[0022] The heat-insulating safety helmet provided in this application includes a helmet body, a cooling fan, and a heat-reflecting unit. The helmet body has a protective space, and the inner wall of the protective space is densely covered with multiple grooves, thereby dividing the inner wall of the protective space into multiple spaced-apart protruding units. The protruding units support the heat-reflecting unit, and the grooves are filled with air. The cooling fan is mounted on the helmet body, and the airflow generated by the cooling fan can blow away the hot air inside the protective space.

[0023] From the perspective of heat insulation performance, this application features multiple grooves on the inner surface of the protective space, covered with heat-reflecting units. The air within the grooves and the heat-reflecting units act as insulation media, reducing the amount of heat entering the protective space through the helmet body from the outside. This solves the problem of the helmet body absorbing heat and causing stuffiness inside the protective space under direct sunlight. The cooling fan dissipates heat emitted by the wearer, keeping the protective space well-ventilated and cool. This application achieves external heat insulation through the grooves and heat-reflecting units, and internal heat dissipation through the cooling fan. These two aspects work together to improve the wearer's comfort in direct sunlight outdoors.

[0024] In terms of product durability, the heat reflective unit is located on the inner wall of the protective space, making it less prone to problems such as scratches, friction, and coating peeling, which helps ensure that the heat reflective unit will not be damaged during long-term use.

[0037] Please refer to the following: Figures 1 to 4 The following describes the heat-insulating safety helmet provided in the embodiments of this application.

[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a safety helmet with heat insulation function, including a helmet body 10, a cooling fan, and a heat reflector unit 20. The helmet body 10 has a protective space for accommodating the head, and the inner wall of the protective space has multiple grooves 12, which divide the inner wall of the protective space into multiple raised units 13 arranged at intervals; the cooling fan is disposed on the helmet body 10, and the air outlet direction of the cooling fan is towards the protective space; the heat reflector unit 20 covers the surface of the raised unit 13.

[0039] Compared with the prior art, the beneficial effects of the heat-insulating safety helmet provided in this application embodiment are:

[0040] The safety helmet with heat insulation function provided in this application embodiment includes a helmet body 10, a cooling fan, and a heat reflector unit 20. The helmet body 10 has a protective space, and the inner wall of the protective space is densely provided with multiple grooves 12, thereby dividing the inner wall of the protective space into multiple protruding units 13 arranged at intervals. The protruding units 13 are used to support the heat reflector unit 20, and the grooves 12 are filled with air. The cooling fan is installed on the helmet body 10, and the airflow generated by the cooling fan can blow away the hot air inside the protective space.

[0041] From the perspective of the product's heat insulation effect, this embodiment of the application has multiple grooves 12 formed on the inner surface of the protective space, and covered with heat-reflecting units 20. The air inside the grooves 12 and the heat-reflecting units 20 serve as heat insulation media, which can reduce the heat entering the protective space through the helmet body 10 from the outside, thus solving the problem of the helmet body 10 absorbing heat and causing stuffiness inside the protective space under direct sunlight. When the cooling fan is running, it can blow away the heat dissipated by the human body, keeping the protective space well-ventilated and cool. This application achieves external heat insulation through the grooves 12 and the heat-reflecting units 20, and achieves internal heat dissipation through the cooling fan. The combined effect of these two aspects improves the comfort of the wearer in outdoor environments with direct sunlight.

[0042] In terms of product durability, the heat reflective unit 20 is located on the inner wall of the protective space, making it less susceptible to external scratches and friction. The coating is less likely to peel off, which helps ensure that the heat reflective unit 20 will not be damaged during long-term use.

[0043] The helmet body 10 is the most basic component of the helmet. Its shape can be directly referenced from the shape of helmets in the existing technology. The helmet body 10 is processed by injection molding. The material can be PVC, PP or ABS plastic. The groove 12 can be integrally formed during injection molding.

[0044] Multiple slots 12 are densely arranged and filled with air to insulate against heat and reduce the heat transmitted through the helmet body 10 from external sunlight. The depth of the slots 12 can be 1mm, 2mm, 3mm, etc., and the width can be 3mm, 5mm, etc. The multiple slots 12 can be arranged in a grid pattern, stripe pattern, or other shapes. The slots 12 divide the inner wall of the protective space into multiple spaced-apart raised units 13. Heat-reflective units 20 are laid on the raised units 13, which provide support.

[0045] The groove 12 can be installed only at the top of the protective space, or it can be installed on the entire inner wall of the protective space. The cooling fan is installed on the helmet body 10. The cooling fan is powered by a battery or solar panel. When running, it can blow air into the protective space to keep the airflow inside the protective space and solve the problem of stuffiness after wearing.

[0046] There are no specific restrictions on the exact location, installation method, model, specifications, and quantity of the cooling fan; users can configure it according to their needs. For example, the cooling fan can be installed at the front of the helmet body 10, corresponding to the wearer's forehead. The cooling fan is located inside the helmet body 10 and blows air through the air outlet 11, with the airflow direction as follows: Figure 2 As indicated by the arrow.

[0047] The heat-reflective unit 20 is a coating or thin film made of heat-reflective materials in the prior art, and can be a single-layer structure or a multi-layer composite structure. For example... Figure 4 As shown by the middle arrow, the heat reflection unit 20 can reflect the heat transmitted through the helmet body 10 from the outside, thus solving the problem of heat entering the protective space after sunlight shines on the helmet body 10, causing stuffiness.

[0048] The heat reflective unit 20 can be fixed to the inner wall of the protected space by means of spraying, printing, gluing, fastener connection, etc. It can be detachably connected or detachably connected.

[0049] Considering that sunlight shines onto the helmet body 10 from the top, please refer to... Figure 1 , Figure 2 and Figure 3 In some possible embodiments, the groove 12 is opened in the area of ​​the inner wall of the protective space corresponding to the top of the wearer's head, and the heat reflection unit 20 covers the opening area of ​​the groove 12, which can isolate most of the heat.

[0050] When the heat reflective unit 20 is installed by adhesive bonding, in order to prevent dust from entering the groove inside the safety helmet after long-term use, an annular dividing groove is also provided on the inner wall of the protective space. The dividing groove surrounds the distribution area of ​​the groove 12, and the edge of the heat reflective unit 20 extends to the outside of the dividing groove and fits tightly against the inner wall of the protective space. After the heat reflective unit 20 is installed, it can seal the opening area of ​​the groove 12, and dust or water will not enter the interior of the groove 12. It can also prevent the adhesive layer from falling off after adhering to dust or water.

[0051] Please see Figure 4In some possible embodiments, the heat reflective unit 20 includes a first heat reflective layer 21, a heat insulation layer 22, and a second heat reflective layer 23. The first heat reflective layer 21 covers the surface of the raised unit 13; the heat insulation layer 22 covers the side of the first heat reflective layer 21 away from the raised unit 13; and the second heat reflective layer 23 covers the side of the heat insulation layer 22 away from the first heat reflective layer 21.

[0052] The first heat-reflective layer 21 and the raised unit 13 are connected by adhesive. The adhesive layer can be directly applied to the surface of the first heat-reflective layer 21. During assembly, the protective paper of the adhesive layer can be peeled off directly, and the heat-reflective unit 20 can be attached to the inner wall of the helmet body 10. Alternatively, adhesive can be applied or brushed onto the inner wall of the helmet body 10 or the surface of the first heat-reflective layer 21 during installation.

[0053] The first heat-reflective layer 21 and the second heat-reflective layer 23 are both thin films made of heat-reflective materials, such as aluminum foil. The heat insulation layer 22 is made of heat-insulating materials, such as cotton, textile fibers, foam board, etc. The first heat-reflective layer 21, the heat insulation layer 22 and the second heat-reflective layer 23 are connected together by means of mechanical extrusion, adhesive bonding, mechanical connection and other methods.

[0054] The heat-reflective unit 20 can also be a heat-reflective coating applied to the surface of the raised unit 13 and the inner wall of the groove 12. The heat-reflective coating can be applied to the inner wall of the protected space by methods such as spraying or silicone printing in the prior art.

[0055] Silicone printing offers high precision and is suitable for printing on irregular surfaces. The specific steps of silicone printing are as follows: First, a heat-reflective coating is printed onto a smooth steel plate with grooves for storing ink. The silicone nozzle is then pressed against the steel plate, allowing it to absorb the coating from the grooves onto its surface. Finally, the silicone nozzle is pressed onto the helmet body 10 like a stamp, transferring the coating to the inner wall of the protective space. The coating is then allowed to dry completely by baking or air drying.

[0056] It should be noted that the heat-reflective coating can be formed directly using existing heat-reflective paints on the market. There are no specific restrictions on the specific type or material ratio of the heat-reflective paint, as long as it can be applied to common safety helmet materials such as ABS and PVC.

[0057] The inner wall of the protective space is provided with multiple buckles 14 at intervals along the circumference. The heat-insulating safety helmet also includes an inner liner, which is snapped into place with the buckles 14. The inner liner has a head strap for supporting the head and a head strap for securing the safety helmet to the wearer's head. The inner liner can be directly inserted and connected to the buckles 14 as a whole. The inner liner can be any product currently available on the market, and there are no restrictions on its specific specifications or models.

[0058] The helmet body 10 is integrally formed with a brim 15 for sun protection and rain protection. The brim 15 is high in the middle and low on both sides, so that rainwater can flow down the slope.

[0059] In some possible embodiments, the top of the safety helmet body 10 is provided with a solar power panel, which is electrically connected to a cooling fan, and the solar power panel is used to power the cooling fan, which is especially suitable for outdoor construction sites.

[0060] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
