The whole helmet body 1, the refrigerating system 2 and the wind power conveying system 3 are connected and communicated with each other through flexible pipes 4.

Above-mentioned wind conveying system 3 includes clarifier casing, turbofan, motor, and motor and turbofan all are in the clarifier casing inside, and the motor drives the turbofan rotation back, can be with the inside of clarifier casing with the ambient air suction in the clarifier casing outside. The flexible tube 4 is connected to the surface of the cleaner case, which includes a bottom cover and a front cover 5 hinged to the bottom cover, and the front cover 5 can be opened to carry the motor and the turbofan.

As shown in fig. 2, the purification system comprises a spark net 6, a filter cotton 7, a particulate filter box 8 and a gas filter box 9 which are arranged in sequence.

The purification system is also in the purifier housing with the spark net 6 on the side near the purifier housing inlet. Wherein, there are four layers in the particulate matter filter box 8, are filter paper, melt-blown cloth, silver ion, active carbon respectively, play the purpose of filtering, sterilizing, adsorbing the toxic gas.

As shown in fig. 3, the refrigeration system 2 includes a refrigerator housing 10, an evaporator 11, a compressor 12, a condenser 13, a heat radiation fan 14, and a cool air fan 15.

The evaporator 11, the compressor 12, the condenser 13 is connected through copper pipes and is located inside the refrigerator shell 10, the cooling fan 14 is installed on the surface of the refrigerator shell 10, the cooling fan 14 faces the condenser 13, the heat at the condenser 13 is exchanged with the external ambient air of the refrigerating system 2, the cold air fan 15 is located in the flexible pipe 4, the axis of the cold air fan 15 and the axis of the flexible pipe 4 are arranged in a collinear mode, the cold air fan 15 faces the evaporator 11, the heat at the position of the evaporator 11 is exchanged with the air blown into the flexible pipe 4, and finally clean and cool air can be brought to an operator who wears the full helmet body 1.
