As respiratory protection equipment, air respirators are widely used in various fields such as fire rescue, metallurgy, chemical industry, shipbuilding and military, etc., and are used by firefighters and related staff to deal with harsh work sites such as fire, leakage of harmful substances, smog, and lack of oxygen. , so as to carry out fire source detection, fire extinguishing, disaster relief, rescue and rescue work.

In the prior art, the air respirator is composed of a cylinder assembly, a decompression system assembly, a mask, an air supply valve and a back frame assembly. When in use, fill the high-pressure gas cylinder in the gas cylinder assembly with 30Mpa compressed air first, then connect the high-pressure gas cylinder to the pressure reducing valve on the air respirator. After opening the gas cylinder valve, the compressed air in the gas cylinder enters the pressure reducing valve The pressure valve, after the first stage of decompression (pressure 0.7MPa), passes through the medium pressure tube and then connects with the air supply valve for secondary decompression, and then enters the mask for the user to breathe. At present, the use time of air respirators is very limited (about 30 minutes). It is difficult for firefighters to complete the rescue work in such a short use time in the modern complex fire environment. Once the air respirators are exhausted, it will directly cause fire hazards. members' sacrifice.

In the prior art and tactics, fire hoses are only used for water supply alone, and firefighters must lay fire hoses for fire extinguishing and cover when performing internal work on the fire scene.

Air respirator and fire hose all are independent independent devices from prior art, do not combine.
