when a fire disaster occurs, indoor air is heated and expanded, the indoor air pressure is often higher than outdoor air pressure, so that the door plate 4 is difficult to open, at the moment, air in the sensing box 6 enters a rodless cavity of the second piston cylinder 24 through the second air pipe 28 and pushes the second piston 25, the stop block 29 is tightly abutted on the door plate 4, thrust on the door plate 4 is generated, and then the door can be opened by assistance, so that the strength is saved, and the door is opened easily; the larger the fire is, the more violent the air expansion in the sensing box 6 is, after the expanded air enters a rodless cavity of the piston cylinder 8, the larger the thrust on the piston 9 is, the longer the moving distance of the touch plate 13 is, the shorter the resistance wire 31 connected to the circuit is, and the larger the current in the circuit is, so that the rotating speeds of the water pump and the smoke exhaust fan 21 are faster, the water pump accelerates the pumping of water, the smoke exhaust fan 21 accelerates the smoke exhaust, and the working efficiency of the water pump and the smoke exhaust fan 21 can be adjusted according to the fire, so that different fire conditions can be met; when the pressing ring 36 and the spray head 23 are staggered, water flow is sprayed out from the spray head 23, the water pressure in the first water pipe 22 is ensured to be the same everywhere, and the situation that part of the spray head 23 does not spray water is prevented; water flow enters the first water pipe 22, reaches the position of the sliding plate 32 and pushes the sliding plate 32 to move downwards, the sliding plate 32 drives the ejector pin 38 to move downwards and puncture the thin film 39, so that the catalyst and the foaming agent are mixed and react, generated foam enters the side groove 42 through the foaming hole 43, and then a gap between the door plate 4 and the door frame 1 is blocked, and smoke leakage is prevented; the output shaft 20 drives the first transmission arm 44 to rotate, the first transmission arm 44 drives the second transmission arm 45 to move up and down, and the second transmission arm 45 drives the connecting rod 47 to swing up and down and further drives the nozzle 46 to swing up and down, so that the spraying range of the nozzle 46 is wider, the fire extinguishing and smoke removing efficiency is improved, and a person can be ensured to be wetted when escaping from a fire door; when the door panel 4 is closed, water in the first water pipe 22 flows into the third water pipe 53 through the second water pipe 51 and the L-shaped hole 52, so that water is supplied to the door panel 4, the aim of cooling is fulfilled, after the door panel 4 is opened, the third pressure spring 50 pushes the sliding block 49 to move in the sliding groove 48, the second water pipe 51 and the L-shaped hole 52 are staggered and block the second water pipe 51, a water source is cut off, water resources are saved, and meanwhile, the water pressure in the first water pipe 22 is ensured to be large enough, so that the spray head 23 can spray water smoothly; glass board 55 receives the pollution in the conflagration easily for the fire fighter can't observe indoor circumstances through glass board 55, and rivers in No. three water pipe 53 can drive water wheels 58 rotatory when water wheels 58, and then the axis of rotation drives the rotation of dirt separator 59, makes dirt separator 59 clean at glass board 55 surface rotation, reaches clear purpose, and the fire fighter of being convenient for observes indoor circumstances through glass board 55.
