▎ 摘　　要

NOVELTY - The helmet has a safety helmet lining (2) fixedly arranged in the safety helmet shell (1). A gap is formed between the safety helmet lining and the safety shell. A control box (3) is fixed on the top side of the helmet lining. A heating refrigeration conversion switch (4) is arranged at the front position of the top surface of the helmet lining close to the forehead. The control box is provided with a power supply system (31), a temperature control system (32) and a heating and refrigeration converter (33) and connected to the heating and cooling conversion switch. The power system is connected with the temperature controller system. The temperature control system and the heating cooling converter are connected to each other. The heating cooling conversion converter is connected to a heating cooling system. USE - Heatable safety helmet capable of heating and refrigerating, controlling temperature used in field of construction and underground operation. Can also be used as an indispensable safety protection product in the field of intelligent wearing. ADVANTAGE - The safety helmet heating and refrigerating integrated design, using semiconductor temperature difference chip for heating and cooling, through the temperature control device and other system to realize the heating and the cooling effect of the safety helmet to the human head. The heating and cooling effect of safety helmet is realized without changing the safety performance, providing a comfortable wearing temperature for the wearer, solving the problem of overheating or ultra-cooling due to high temperature in summer and low temperature wearing in winter. The flannel layer has high skin-friendly feeling and heat conduction performance. The heat insulating layer prevents the heat exchange between the upper and lower heat conducting layers. The phase change layer heat accumulation is capable of absorbing and storing the heat generated by the heat end of the semiconductor refrigerating component into the surface of the graphene layer for radiating.
