Description

technical field

[0001] The invention belongs to the field of fire fighting equipment, and in particular relates to a wearable air respirator. Background technique

[0002] Air breathing apparatus is an important fire-fighting equipment, mainly used in fire-fighting, chemical industry, shipbuilding, petroleum, smelting, factories, mines, laboratories, etc. Safely carry out fire extinguishing, emergency rescue and rescue work in the environment. The air respirator currently used is a positive pressure air respirator, which has the advantages of convenient maintenance, comfortable wearing, and stable performance. It is an ideal personal respiratory protection device for emergency rescue and fire fighting operations.

[0003] The structure of the positive pressure air respirator is relatively complicated, and the air source is an air tank filled with high-pressure air. During the fire fighting process, the high-pressure air tank carried on the back is prone to explosion accid...
