Description

Technical Field

[0001] This utility model relates to the field of fire helmet technology, specifically a ventilated and heat-dissipating fire helmet. Background Technology

[0002] Fire helmets are essential personal protective equipment worn by firefighters when performing firefighting and rescue missions. In complex, ever-changing, and dangerous fire scenes, they provide protection for the firefighters' heads. Fire scenes are often accompanied by high temperatures, flames, dense smoke, and various objects that may fall. Fire helmets can resist these dangerous factors and effectively prevent head injuries such as impacts, burns, and scalds. They not only protect the lives of firefighters but also enhance their ability to move in harsh environments, enabling them to focus more on completing rescue missions.

[0003] The design of fire helmets takes into account the flexibility and comfort of firefighters when performing tasks, while also taking into account protective performance and durability. It is an indispensable part of the modern fire equipment system, reflecting a high degree of care and attention to the life safety of firefighters, and is one of the key pieces of equipment to ensure that firefighters can charge into the fire.

[0004] Due to the harsh environment and high temperature at fire scenes, the ventilation and heat dissipation capabilities of fire helmets are particularly important. Current fire helmets only rely on ventilation holes or added cooling fans for auxiliary heat dissipation. Although these methods have a certain heat dissipation capacity, they mainly depend on airflow to remove heat from inside the helmet, resulting in low heat dissipation efficiency. Furthermore, they are unable to quickly dissipate the heat accumulated around the firefighter's head, which can cause discomfort and affect their rescue efficiency and judgment in high-temperature environments such as fire scenes. Therefore, a ventilated and heat-dissipating fire helmet is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ventilated and heat-dissipating fire helmet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilated and heat-dissipating fire helmet includes a helmet body, which comprises an outer shell and an inner heat-conducting liner. The inner cavity of the outer shell is provided with a heat dissipation component. The inner heat-conducting liner includes an adjustable headband, a heat-conducting disc above the adjustable headband, and a plurality of inner head supports between the adjustable headband and the heat-conducting disc. The inner cavity of each inner head support is provided with a heat-conducting plate. A plurality of head support slots are formed at the edge of the heat-conducting disc. The bottom end of each inner head support is fixedly connected to the inner wall of the adjustable headband, and the top end of each inner head support passes through the head support slots and engages with them. The helmet body is disposed outside the inner heat-conducting liner and is fixedly connected to the inner heat-conducting liner.

[0008] As a further optimization of this utility model, a heat insulation head support plate is provided below the heat conduction plate, the heat insulation head support plate is fixedly connected to the heat conduction plate and a gap is left between the heat insulation head support plate and the heat conduction plate.

[0009] As a further optimization of this utility model, the top of the heat-conducting plate is fixedly connected to a heat-conducting base, a heat-conducting support is provided above the heat-conducting base, and a number of heat dissipation fins are provided on the heat-conducting support.

[0010] As a further optimization of this utility model, the heat-conducting base is provided with symmetrical snap-fit ​​protrusions on both sides, and the heat-conducting support is provided with symmetrical snap-fit ​​grooves on the inner sidewall. The heat-conducting base and the heat-conducting support are snapped together by the snap-fit ​​protrusions and snap-fit ​​grooves.

[0011] As a further optimization of this utility model, the heat dissipation fins are arranged radially at equal intervals, and the surface of the heat dissipation fins is serrated.

[0012] As a further optimization of this utility model, the top of the outer helmet shell is symmetrically provided with air inlets, and the bottom of the outer side of the outer helmet shell is provided with multiple heat dissipation vents.

[0013] As a further optimization of this utility model, the heat dissipation component includes a heat dissipation fan, which is located directly above the heat-conducting support. The heat dissipation fan is fixedly connected to the top of the inner cavity of the outer shell through connecting rods on both sides.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the outer shell and the inner heat-conducting liner can be combined to form a complete helmet. The outer shell provides good protection and structural strength, while the inner heat-conducting liner not only better adapts to the firefighter's head for a better wearing experience, but also has excellent thermal conductivity, enabling rapid collection and conduction of heat around the firefighter's head, allowing for timely dissipation and improving overall heat dissipation. The heat dissipation liner can also rapidly dissipate the heat collected inside the outer shell and the inner heat-conducting liner, ensuring effective heat dissipation within the helmet and improving the firefighter's wearing comfort. This prevents poor heat dissipation from affecting the firefighter's rescue efficiency and judgment in high-temperature environments such as fire scenes. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figures 1-9 This utility model provides a technical solution:

[0029] A ventilated and heat-dissipating fire helmet includes a helmet body 1, which includes an outer shell 11 and an inner heat-conducting component 12. The inner cavity of the outer helmet body 1 is provided with a heat dissipation component 13. The inner heat-conducting component 12 includes an adjustable headband 121, a heat-conducting plate 122 above the adjustable headband 121, and a plurality of inner head supports 123 between the adjustable headband 121 and the heat-conducting plate 122. The inner cavity of the inner head supports 123 is provided with heat-conducting plates 124. A plurality of head support slots 125 are opened at the edge of the heat-conducting plate 122. The bottom end of the inner head support 123 is fixedly connected to the inner wall of the adjustable headband 121, and the top end of the inner head support 123 passes through the head support slots 125 and is engaged with the head support slots 125. The helmet body 1 is disposed on the outside of the inner heat-conducting component 12, and the helmet body 1 is fixedly connected to the inner heat-conducting component 12.

[0030] As a further implementation of this solution, a heat-insulating head support plate 126 is provided below the heat-conducting plate 122. The heat-insulating head support plate 126 is fixedly connected to the heat-conducting plate 122, and a gap is left between the heat-insulating head support plate 126 and the heat-conducting plate 122. A heat-conducting base 127 is fixedly connected to the top of the heat-conducting plate 122. A heat-conducting support 128 is provided above the heat-conducting base 127. Several heat dissipation fins 129 are provided on the heat-conducting support 128. Snap-fitting protrusions 1271 are symmetrically provided on both sides of the heat-conducting base 127. The inner sidewall of the heat support 128 is symmetrically provided with snap-fit ​​grooves 1281. The heat-conducting base 127 and the heat-conducting support 128 are snapped together by snap-fit ​​protrusions 1271 and snap-fit ​​grooves 1281. The heat dissipation fins 129 are arranged radially at equal intervals. The surface of the heat dissipation fins 129 is serrated, which has good heat conduction ability and can quickly collect and conduct heat from the firefighter's head area, so that the heat from the firefighter's head area can be dissipated in time, thereby improving the overall heat dissipation effect.

[0031] As a further implementation of this solution, the top of the outer shell 11 is symmetrically provided with air inlets 14, and the bottom of the outer side of the outer shell 11 is provided with multiple heat dissipation vents 15. The air inlets 14 can draw cold air from the outside into the helmet body 1, and the heat dissipation vents 15 can expel hot air from the helmet body 1, thereby achieving air heat exchange.

[0032] As a further implementation of this solution, the heat dissipation component 13 includes a heat dissipation fan 131, which is located directly above the heat-conducting support 128. The heat dissipation fan 131 is fixedly connected to the top of the inner cavity of the outer shell 11 through connecting rods 132 on both sides. The heat dissipation component 13 can quickly dissipate the heat collected inside the outer shell 11 and the heat-conducting component 12 of the inner lining to ensure the heat dissipation effect inside the helmet 1, thereby improving the wearing comfort of firefighters and avoiding the impact on the firefighters' rescue efficiency and judgment ability in high-temperature environments such as fire scenes due to poor heat dissipation.

[0033] Workflow: The outer shell 11 and the inner heat-conducting liner 12 can be combined to form a complete helmet 1. The outer shell 11 provides good protection and structural strength to the helmet 1. The inner heat-conducting liner 12 not only better adapts to the firefighter's head for a better wearing experience, but also has good thermal conductivity, enabling rapid collection and conduction of heat from the firefighter's head circumference, allowing the heat to dissipate promptly and improving overall heat dissipation. When wearing, adjusting the headband 121 allows for a better fit for the firefighter. The headband 125 provides a mounting base for the inner headband 123, which offers cushioning to protect the firefighter's head. The heat-insulating headband 126 not only supports the firefighter's head but also isolates it from the heat-conducting plate 122, preventing heat absorbed by the plate from affecting the firefighter's comfort. Adjusting the headband 121 will cause the area around the firefighter's head to become stuffy and hot, thus improving the internal heat conduction... Plate 124 can quickly absorb heat from the firefighter's head and direct it to the heat-conducting plate 122. The heat-conducting plate 122 then quickly conducts the heat to the heat-conducting base 127 and the heat-conducting support 128. Finally, the heat is quickly dissipated through the heat dissipation fins 129. The heat dissipation fins 129, with their equidistant radial arrangement and serrated surface, increase the surface area in contact with air, thereby improving heat dissipation efficiency. The heat-conducting base 127 and the heat-conducting support 128 are connected by a snap-fit ​​protrusion 1271 and a snap-fit ​​groove 1281 for heat dissipation. The connecting rod 132 in component 13 can fix the cooling fan 131 to the top inside the outer shell 11. The cooling fan 131 draws in outside air through the air inlet 14 and blows it into the outer shell 11. This not only accelerates the airflow inside the outer shell 11 and achieves a better heat dissipation effect, but also allows the heat on the cooling fins 129 to be quickly dissipated through the heat dissipation port 15. This improves the wearing comfort of firefighters and avoids affecting their rescue efficiency and judgment in high-temperature environments such as fire scenes due to poor heat dissipation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
