Safety helmet with automatic heat dissipation function

Abstract

The present invention discloses a safety helmet with the automatic heat dissipation function. The safety helmet comprises a helmet shell, a helmet brim is fixedly installed on the lower end face of the helmet shell, a lining is fixedly installed in the helmet shell, a sealing ball is arranged between the lining and the helmet shell, and the sealing ball is fixedly installed on the inner wall of the helmet shell. A plurality of magnet exciting coils are annularly arranged on the inner wall of the sealing ball at equal intervals, balance weight liquid is injected into the lower half portion in the sealing ball, a floating plate is arranged on the balance weight liquid, the floating plate floats on the balance weight liquid, a sealing sliding sleeve is arranged on the periphery of the floating plate, and the floating plate is connected into the sealing ball in a sealed and sliding mode through the sealing sliding sleeve. According to the helmet, the motor can drive the exhaust fan bladesto rotate after being powered on, hot air in the helmet shell is continuously exhausted outwards, air circulation in the helmet shell is promoted, evaporation of sweat on the head of a constructor ispromoted, the constructor can feel cool continuously, the heatstroke phenomenon of the constructor is greatly reduced, and the heat dissipation effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of safety helmets, in particular to a safety helmet with an automatic heat dissipation function. Background technique [0002] Safety helmet is a kind of dome cap that is used to protect the top of the head. There is a certain space between the cap shell and the cap liner to buffer and disperse the instantaneous impact force, so as to avoid head injury. Existing safety helmets are widely used. Used on construction sites, workers generally wear hard hats and work on the site in hot weather. However, traditional safety helmets only dissipate heat from the head through a small number of cooling holes around the hat, and the cooling effect is poor, which may easily cause heatstroke of construction workers. [0003] In order to solve the above problems, the present invention provides a safety helmet with an automatic heat dissipation function. Contents of the invention [0004] The purpose of the present inve...
