When the automatic driving mechanism 5 slides upwards to contact with the inclined surface stop lever 44, the automatic driving mechanism 5 will make the inclined surface stop lever 44 move forwards, and then the inclined surface stop lever 44 will make the first sliding connecting rod 42 slide forwards in the first sliding sleeve 41, the first spring 43 is compressed, the inclined surface stop lever 44 moves forwards to temporarily stop contacting with the sliding fire door 3, one can manually make the sliding fire door 3 slide downwards in the sliding track 2, when the sliding fire door 3 slides downwards to contact with the top of the connecting plate 1, the sliding fire door 3 can isolate and extinguish the fire, when one temporarily does not need to use the fire door, the automatic driving mechanism 5 slides downwards to temporarily stop contacting with the inclined surface stop lever 44, the first spring 43 resets to make the inclined surface stop lever 44 move backwards, and then the inclined surface stop lever 44 will make the first sliding connecting rod 42 slide backwards in the first sliding sleeve 41, when the inclined surface bar 44 moves to the rear side and contacts with the sliding fireproof door 3 again, the inclined surface bar 44 can block the sliding fireproof door again, people can stop using the fireproof door temporarily, and when the automatic driving mechanism 5 slides upwards again and contacts with the inclined surface bar 44, the sliding fireproof door 3 can slide downwards again to isolate and extinguish the fire.

When a fire heats the water containing pipe 51, steam generated by the water containing pipe 51 can enable the first sliding driving rod 53 to slide upwards, and further the sliding water plugging rod 55 can slide upwards in the second sliding sleeve 54 and the water discharging frame 52, when the first sliding driving rod 53 slides upwards to be in contact with the inclined plane stop lever 44, the first sliding driving rod 53 can enable the inclined plane stop lever 44 to move forwards, the temperature of the water containing pipe 51 can be gradually reduced, the second spring 56 can assist the first sliding driving rod 53 to slide downwards to reset, when the first sliding driving rod 53 slides downwards to be temporarily stopped to be in contact with the inclined plane stop lever 44, the first spring 43 can assist the inclined plane stop lever 44 to slide backwards to reset, in order to enable the water containing pipe 51 to be heated to generate steam, people can pour proper amount of tap water into the water discharging frame 52 regularly, and tap water in the water discharging frame 52 can slide into the water containing pipe 51.

In order to avoid that the sliding water blocking rod 55 is accidentally pushed upwards and the steam in the water discharging frame 52 is discharged, when people need to discharge the steam in the water discharging frame 52, people can simultaneously and manually move the connecting link rod 64 outwards, the connecting link rod 64 can enable the sliding baffle 62 to slide outwards on the third sliding sleeve 61, the third spring 63 is stretched, when the sliding baffle 62 slides outwards to temporarily stop contacting with the top end of the sliding water blocking rod 55, the sliding baffle 62 can temporarily block the sliding water blocking rod 55, and the steam in the water discharging frame 52 can be discharged, when people temporarily do not need to enable the steam in the water discharging frame 52 to be discharged, people can quickly release the connecting link rod 64, the third spring 63 is reset to enable the sliding baffle 62 to slide inwards on the third sliding sleeve 61, and when the sliding baffle 62 slides inwards to again contact with the top end of the sliding water blocking rod 55, the sliding baffle 62 can block the sliding water blocking rod 55, and the sliding water blocking rod 55 is locked, so that the fire door effectively avoids the situation that steam is discharged accidentally.

People are difficult to realize that the connecting rod 64 moves outwards at the same time, so when the sliding fireproof door 3 slides downwards to be contacted with the second sliding connecting rod 73, the sliding fireproof door 3 can lead the second sliding connecting rod 73 to slide downwards in the fourth sliding sleeve 71, and then the second sliding connecting rod 72 moves downwards, the fourth spring 74 is compressed, when the second sliding connecting rod 73 slides downwards to be contacted with the connecting rod 64, the second sliding connecting rod 73 can lead the connecting rod 64 to slide outwards, when the sliding fireproof door 3 slides upwards to temporarily stop being contacted with the second sliding connecting rod 73, the fourth spring 74 is reset to lead the second sliding connecting rod 73 to slide upwards on the second sliding connecting rod 72 for resetting, when the second sliding connecting rod 73 slides upwards to temporarily stop being contacted with the connecting rod 64, the third spring 63 is reset to lead the connecting rod 64 to move inwards for resetting, so this prevent fire door has realized need not people's manual messenger and has connected pole 64 and move to the outside, the effectual intensity of labour who alleviates people.

In order to prevent the sliding fireproof door 3 from being scalded by overhigh temperature, people can pour a proper amount of tap water into the charging frame 81, meanwhile, the striker plate 83 is fixed by hand, when people need to cool the sliding fireproof door 3, the striker plate 83 can be loosened, the rotary striker plate 83 rotates on the fixed plate 82 under the action of the gravity of tap water, the torsion spring 84 is stretched, then the tap water in the loading frame 81 can be poured onto the sliding fireproof door 3, the tap water can rapidly cool the sliding fireproof door 3, after the tap water in the loading frame 81 is completely poured out, the return of the torsion spring 84 allows the rotary striker plate 83 to return rotationally on the fixed plate 82, and when the rotary striker plate 83 rotates to be in contact with the loading frame 81 again, then people can pour proper amount of running water into the material loading frame 81 once more, so this prevents that the condition of scalding people from appearing effectively.

When the sliding fireproof door 3 slides downwards, the sliding fireproof door 3 can make the inclined surface driving rod 95 move downwards, when the inclined surface driving rod 95 moves downwards to be contacted with the third sliding driving rod 94, the inclined surface driving rod 95 can make the third sliding driving rod 94 slide towards the front side, further the third sliding driving rod 94 can make the sliding stop rod 92 slide towards the front side in the fifth sliding sleeve 91, the fifth spring 93 is compressed, when the third sliding driving rod 94 slides towards the front side to be temporarily stopped to be contacted with the stop plate 83, the rotary stop plate 83 can rotate on the fixed plate 82 due to the gravity of tap water in the charging frame 81, the tap water in the charging frame 81 can be poured onto the sliding fireproof door 3, due to the gradual reduction of the tap water in the charging frame 81, the torsion spring 84 can reset the rotary stop plate 83 to rotate on the fixed plate 82, then when a worker manually slides the sliding fireproof door 3 upwards, the sliding fireproof door 3 can make the inclined surface driving rod 95 move upwards, when the inclined surface driving rod 95 moves upwards to temporarily stop contacting with the third sliding driving rod 94, the fifth spring 93 resets to enable the sliding blocking rod 92 to slide and reset towards the rear side in the fifth sliding sleeve 91, the sliding blocking rod 92 slides towards the rear side to be contacted with the rotating baffle 83 again, the sliding blocking rod 92 limits the rotating baffle 83, and the fireproof door can be cooled according to the required interval.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
