Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a helmet with adjustable heat dissipation. Background Art

[0002] A helmet is a head protection device. It is a hat worn by soldiers during training and combat, and is an indispensable tool for people's transportation. It is divided into military helmets, police helmets and civilian helmets. It is mostly semicircular and mainly consists of three parts: shell, lining and suspension device. The shell is made of special steel, fiberglass, reinforced plastic, leather, nylon and other materials to resist the damage to the head caused by bullets, shrapnel and other striking objects. In ancient China, it was called helmet, head armor, helmet or head helmet. Modern helmets are mainly composed of helmet shell, lining and suspension system. Due to different requirements for use in various activities, there are many structures and styles of helmets. Usually, the shell of the helmet is made of high-strength materials, such as metal, engineering plastics, Kevlar fiber, etc., which absorbs most of the impact force through its deformation; the lining material has the functions of sweat absorption, warmth preservation and shock absorption, and military helmets often have the function of further reducing the impact force and preventing shell fragments from injuring the head; the suspension system is the part between the shell and the lining, which can usually be adjusted to adapt to the differences in the head shapes of different wearers. Some special-purpose helmets are also equipped with headphones and microphones, as well as sockets for installing additional equipment such as cameras and flashlights.

[0003] Although the head has a relatively small area, it is one of the areas most susceptible to thermal stimulation and one of the most important parts of the body for achieving thermal comfort. Helmets can make the head feel stuffy and uncomfortable in the summer. The reduced heat dissipation of the head caused by wearing a helmet and the accumulation of sweat give people a damp feeling, which can cause discomfort. Therefore, we propose a helmet with adjustable heat dissipation to overcome the above problems. Utility Model Content

[0010] In order to further improve the usability of the helmet with adjustable heat dissipation, the solution adopted by the utility model is that each of the heat exchange gaps is inclined in a manner of expanding from the front of the heat dissipation structure toward the rear of the heat dissipation area.
