Air supply pipeline for inspiration

Abstract

The invention discloses an air supply pipeline for inspiration. An opening in the internal hole direction of the air supply pipeline is formed in a pipe wall of the air supply pipeline; the pipe wallis made of rigid materials; the parts, on the two sides of the opening, of the pipe wall are separated by a distance; the part, on one side of the opening, of the pipe wall is fixedly connected with asealing strip; and the other side of the sealing strip is movably connected with the part, on the other side of the opening, of the pipe wall.

Description

technical field [0001] The present application relates to a gas supply pipeline. Background technique [0002] There are many combustible decorations, chemical fiber carpets and furniture filled with foam plastics in modern buildings. These combustibles will produce a lot of toxic smoke and heat during combustion, and consume a lot of oxygen. In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. According to the statistics of the causes of casualties in fires in the UK, the death toll due to suffocation due to carbon monoxide poisoning or other toxic smoke generally accounts for 40% to 50% of the total death toll, and among the people who were burned to death, most of them were poisoned first. Burned to death after asphyxiation. When a fire breaks out, because combustion consumes a lot of oxygen, the oxygen concentration in the air drops significantly. If people stay in this hypoxic environment for a long tim...

Problems solved by technology

Such a technical measure has the disadvantage of being inconvenient to use the air outlet, and cannot continuously inhale fresh air, which will cause a great psychological burden to the escaped personnel and easily cause the risk of scrambling for the air outlet
