Intelligent safety helmet with detection function

The utility model relates to the technical field of safety helmets, in particular to an intelligent safety helmet with a detection function, which is characterized in that an arc-shaped top rib is arranged at the center of the outer surface of a helmet shell, and a cylindrical barrel is mounted on the outer surface of the helmet shell close to a helmet brim; a connecting shell is arranged between the top rib and the barrel, a first containing box and a second containing box are installed on the inner surface of the helmet shell, air outside the helmet shell is pumped into the barrel through a fan, a temperature sensor and a humidity sensor are placed in the first containing box, and a gas sensor and an oxygen sensor are placed in the second containing box. Detection of temperature, humidity, gas content and oxygen content in ambient air is completed respectively. If the detection values of the temperature, the humidity and the gas content exceed the set values or the detection value of the oxygen content is l
