Problems solved by technology

[0002] Existing airtight protective clothing contains the exhaust gas from breathing and the heat and water vapor discharged from the human body. Not only is the transparent observation window on the hood easy to accumulate water vapor and affect the sight, but also the weather with a slightly higher temperature is extremely stuffy.

[0003] In the existing airtight air-supply protective clothing, the fan outlet is generally connected to the hood through a plastic air outlet pipe, and the air outlet will generate a large decibel noise. Because the sound source is close to the user's ear, the user is seriously disturbed by the noise and feels uncomfortable. , can become irritable after a long time

[0004] Moreover, most of the existing airtight air-supply protective clothing adopts structures such as an external fan for air supply, and the external fan needs an external belt to be hung on the waist to facilitate carrying, which causes many gaps between the fan, the belt and the protective clothing. Clean dead corners, easy to attach viruses, and the external fan structure makes the protective clothing unable to be disinfected by spraying, which makes the protective clothing can only be sent for separate disinfection to ensure safe use once it is taken off, causing users to wear It must be closed for several hours after boarding, which is very inconvenient
