Abstract

The invention discloses an air supply pipeline. A pipe wall of the air supply pipeline is provided with a linear-shaped opening or an openable linear-shaped opening, a pipe wall on the side edge of the opening is connected with a sealing piece, the pipe wall on one side of the opening is fixedly connected with one end of the sealing piece, the other end of the sealing piece and a pipe wall on theother side of the opening are magnetically attracted to each other, or the other end of the sealing piece and another sealing piece which is connected with the pipe wall on the other side of the opening are magnetically attracted to each other, a vent pipe is capable of being inserted into the opening and communicating with an internal hole of the air supply pipeline by moving the sealing pieces,the sealing pieces are wrapped around the vent pipe through magnetic attraction or the air supply pipeline pipe wall on the side edge of the opening is wrapped around the vent pipe.

Description

technical field [0001] The present application relates to an air supply duct for inhalation. Background technique [0002] In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. [0003] When a fire breaks out in a building, in order to avoid the damage of smoke to people, the prior art is as follows: an air supply pipeline is arranged inside or outside the structure of the building, and the above-mentioned air supply pipeline is provided with an air outlet at a suitable position on the floor. The air inlet of the air supply pipeline extends to the outside of the building to communicate with the gas outside the building, and the air supply pipeline extends downwards and then extends a certain distance to the outside of the building. Therefore people can inhale the air that is not affected by smog by means of the air outlet, then hold back the breath and advance for a period of time such as 5-20 seconds, exhale ...
