The high-pressure air pump 8 can be arranged in a building, and the high-pressure air outlets are arranged around the opening 3. One end of the air duct 9 is connected to the air outlet 10 of the high-pressure air pump 8, and the other end is connected to the high-pressure air outlet.

[0022] In this embodiment, the sprinkler assembly includes a water tank 11, a water pipe 13, a water pump 12, and a plurality of nozzles 14.

[0027] In the specific implementation of this embodiment:

[0028] When fire information is detected, the fire door body 1 is in a tightly closed state. When the human infrared sensor simultaneously detects that someone is approaching the emergency escape door 2, the microcontroller 7 transmits information to the synchronous linear motor 5 to move it upward, and simultaneously transmits information to the high-pressure air pump 8 and the water pump 12. High-pressure gas and water are sprayed around the opening 3 to facilitate people's escape. The sprayed water has a purifying effect on smoke, and the high-pressure gas can minimize the amount of smoke that enters the escape passage, thereby extending the escape time for the escaping people. When the person is out of trouble, the door closing button is turned off to close the emergency escape door 2.
