Problems solved by technology
Due to the good airtightness of fully sealed chemical protective clothing, it is complicated to operate and wear, so two people are generally required to operate when wearing a fully sealed chemical protective clothing. Those who wear fully sealed chemical protective clothing should wear positive pressure air respirators in advance and then wear chemical protective clothing.
There is no emergency breathing device in the chemical protective clothing currently configured. Once the wearer encounters a sudden gas supply equipment failure and stops the gas supply, it will bring the risk of suffocation to the wearer.

Embodiment Construction
[0012] exist figure 1 Among them, a fully sealed chemical protective suit with an emergency breathing port, including a jacket 2 with a head cap 1 and trousers 3, the head cap 1 is provided with a transparent lens 4, and the transparent lens 4 is provided with a protruding threaded ring 5 , The ventilation hole 6 is located on the ring 5, and a cover 7 matching it is screwed into the ring 5.
[0013] When the emergency breathing port needs to be opened, the cover 7 is twisted out of the ring 5 to achieve the purpose of communicating with the outside air. When the cover 7 is tightened on the ring 5, the chemical protection suit remains sealed. When the vent hole 7 needs to be used, the cover 7 of the vent hole can be unscrewed to communicate with the outside air for the wearer to breathe, which can prevent the wearer from being fed when the wearer encounters a sudden gas supply equipment failure and stops the air supply. presents a suffocation hazard.
