The duct of the fan 61 communicating with each second blowing port 62 is arranged so as to avoid the position where the duct reserving section 15 communicates with the duct 1.

The size of part of people is less, and the friction force of the buffering air bag assembly when the part of people slides in the pipeline 1 is small, so that the deceleration effect is poor. Therefore, the escaper can wear the inflatable obeying pipeline 1 to slide down, and the surface material of the inflatable garment can be the same as that of the buffer air bag assembly. The size of the personnel can be increased through the inflatable garment, so that the extrusion force of the buffering air bag assembly is larger, and the deceleration effect is better when the automobile falls.

The pipeline 1 is separated from the pipeline retention zone 15 by a pipeline door 22. In the event of a fire alarm, the lighting system 7 within the pipeline 1 is turned on. When a person enters the pipeline detention area 15, the switch is pressed, the door leading to the pipeline 1 is opened, after one person jumps into the pipeline 1, the pipeline door 22 is automatically closed, and the rest persons stay in the pipeline detention area 15 for waiting. Several seconds later the switch may then be pressed to open the pipe door 22 and continue to jump in from the pipe 1. Thus, the air which is sent into the pipeline 1 through the air inlet system 6 can be prevented from largely leaking away from the pipeline detention area 15 without reaching the upper part of the pipeline 1, and the air quantity in the pipeline 1 is ensured to be sufficient. When the temperature sensor 17 detects that the temperature in the pipe stagnation area 15 rises to a critical value, the fire door 16 receives a signal and automatically closes to prevent the fire from entering the pipe 1. And people who have not been escaped from the floor need to escape from the pipeline at the upper layer or the lower layer along the stair walkway.

Example 2

The number of the second airbag 3 facing the first airbag 2 may be one or more. For example, the larger first airbag 2 is one in number, and the smaller second airbag 3 is two in number, and the two second airbags 3 are arranged adjacently. The distance between the upper and lower adjacent air bags can be 5-10 cm; the upper air bag and the lower air bag which are adjacent can be tightly attached to each other, so that the lower air bag can play a certain supporting role on the upper air bag.

The horizontally staggered angle between the gaps of the upper and lower adjacent air bag groups is between 30 and 180 degrees. When the angle of the horizontal staggered upper and lower gaps is 30-50 degrees, when the escape personnel falls and reaches the next layer of air bag group, the horizontal deflection angle of the escape personnel relative to the upper layer of air bag group is smaller, and the falling posture of the escape personnel is easily adjusted to be the contact between the hip and the air bag below, so that the hip is utilized for further buffering, the buffering effect is better, and the escape personnel are not easy to be injured. The horizontally staggered angle between the gaps of the upper and lower adjacent air bag groups is between 30 and 180 degrees, and the characteristic is also suitable for
