The helmet has a basic protection function of a safety helmet and forms a closed space in combination with the face shield 10. The protective clothing is a one-piece type and is worn through a sealing zipper. The neck of the protective suit and the neck of the helmet are connected by flexible materials, so that the flexibility and the sealing performance of joints are guaranteed. The back and the lower limbs of the protective suit are internally provided with the supporting frameworks to play a role in supporting all parts of the system, reducing the load of workers and preventing the mechanical damage of the body.

2. A respiratory system:

because sealed the entering of protective clothing completely cut off the air, the scheme that this scheme adopted 2 air supplies of compressed gas cylinder provides the wearer and breathes, mixes oxygen and nitrogen gas, the oxygen concentration in the simulation atmosphere. The gas sensor is used for detecting the concentration of gas in the protective clothing, and the negative feedback system is used for controlling the valve of the compressed gas cylinder 2 to change the gas supply amount, so that the concentration of oxygen in the protective clothing is maintained. Under normal conditions, even if the oxygen demand of a wearer changes due to different working strengths, the requirement can be met as long as the oxygen concentration in the protective clothing is close to the atmospheric condition. Compared with oxygen masks, filtering respirators and other schemes, the scheme reduces the oppression of the breathing device on the face and reduces the breathing resistance. In order to prevent the problems that the oxygen demand of a wearer changes too much in the high-intensity working process and the negative feedback system cannot adjust the oxygen supply timely, the scheme monitors the heart rate and the breathing frequency of the wearer in real time, establishes a physical sign model to predict the oxygen demand, increases the oxygen supply rate in advance and prevents the oxygen deficiency phenomenon in the high-intensity working process.

The carbon dioxide exchanged by breathing needs to be removed in time to ensure that the gas components in the protective clothing are suitable for breathing. In order to reduce the whole weight of the protective clothing, the carbon dioxide is selectively discharged outside the protective clothing through a membrane separation mode. The moisture is removed by adopting a mode of condensing and collecting a semiconductor condensing sheet.
