[0002] Air respirator is a self-contained open air respirator. It is widely used in firefighting, chemical industry, shipbuilding, petroleum, smelting, warehouse, laboratory, mining and other departments. It is used by firefighters or emergency rescue personnel to safely and effectively extinguish fires, rescue and rescue in various environments such as dense smoke, toxic gas, steam or lack of oxygen. Air respirator is also called gas storage gas mask, sometimes also called fire mask. It uses compressed gas cylinder as gas source, but the gas contained in the cylinder is compressed air. With the development of society, when users need to breathe normally in dangerous environments, they use air respirators.

[0003] The inventor discovered in his daily work that workers wear air respirators on their faces so that they can breathe normally in dangerous environments. Currently, most workers need to adjust multiple drawstrings to match the limit rings when wearing air respirators so that the air respirators can fit tightly against the user's face. However, during the adjustment process, workers have too many drawstrings, which makes it time-consuming for workers to wear the air respirators, which in turn causes inconvenience for workers when wearing the air respirators.
