They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. Steel fire doors are a type of fire door. They use steel materials to make door frames, door leaf frames and door leaf panels. If the door leaf is filled with material, it is filled with fireproof and heat-insulating materials that are non-toxic and harmless to the human body, and is equipped with fireproof hardware accessories to form a door with certain fire resistance.

[0003] Steel fire doors are installed on door frames. The sealing between the fire doors and the door frame edges is poor. In addition, the steel fire doors heat up in the fire and deform due to the high temperature, which increases the gap between the fire doors and the door frame, making it easy for smoke to escape and cause smoke to spread. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-5 A steel fire door that prevents smoke diffusion includes a door frame 1 and a door body 2. The door body 2 is rotatably connected to the door frame 1. The upper end of the door frame 1 is fixedly connected to a box body 3. The door frame 1 and the box body 3 are an integrated structure. A smoke sensing mechanism 4 is fixedly connected to one side of the box body 3. A spray mechanism 5 is connected to the box body 3. A groove 6 is opened on the door frame 1. A sealing plate 7 is connected to the groove 6. A liquid dispensing pipe 8 is connected in the groove 6. The liquid dispensing pipe 8 is connected to the spray mechanism 5. Several second water outlet pipes 9 are connected to the liquid dispensing pipe 8 at equal intervals along the length direction. One end of each second water outlet pipe 9 extends to the groove 6 and is arranged toward the door body 2.

[0023] Working process:

[0024] After the smoke sensing mechanism 4 detects smoke, the spray mechanism 5 starts to release spray water, and the released spray water falls from the upper end of the door frame 1. The falling water falls on the door body 2, cooling the door body 2 to prevent the door body 2 from being deformed due to high temperature. At the same time, a part of the spray water released by the spray mechanism 5 enters the liquid distribution pipe 8, and the water in the liquid distribution pipe 8 is released from different second water outlet pipes 9. The released water enters the gap between the door frame 1 and the door body 2, sealing the gap between the door frame 1 and the door body 2 to prevent smoke from diffusing and releasing through the gap.

[0025] Example 2: In Example 1, when the smoke is sensed by the smoke sensing mechanism 4, the particles in the smoke adhere to the smoke sensing mechanism 4, which is inconvenient to clean. Figure 3As another preferred embodiment of the present invention, the difference from embodiment 1 is that the smoke sensing mechanism 4 includes a smoke sensor 41, a mounting groove 42 is opened on the box body 3, the mounting groove 42 is connected to the smoke sensor 41, a fixing ring 43 is clamped on the box body 3, the mounting groove 42 is located on the inner side of the fixing ring 43, and a filter 44 is fixedly connected to the fixing ring 43. The smoke passes through the filter 44 and contacts the smoke sensor 41. The filter 44 filters the particulate matter in the smoke to prevent the particles from sticking to the smoke sensor 41. When the fixing ring 43 is removed, the fixing ring 43 drives the filter 44 to move, making it easy to remove and clean.

[0026] Example 3: In Example 1, after the spraying mechanism 5 sprays liquid to cool the door body 2, it is inconvenient to replenish the liquid in the spraying mechanism 5. Figure 4 As another preferred embodiment of the present invention, the difference from embodiment 1 is that the spray mechanism 5 includes a pump 51, which is fixedly connected to the box body 3, and a liquid storage component 52 is fixedly connected to the box body 3. The inlet of the pump 51 is connected to the liquid storage component 52 through a first connecting pipe, and the outlet of the pump 51 is connected to a second connecting pipe. One end of the second connecting pipe extends to the outside of the box body 3 and is connected to a horizontal pipe 53. The bottom end of the horizontal pipe 53 is connected to a plurality of first water outlet pipes 54 at equal intervals along the length direction, and one of the first water outlet pipes 54 is connected to the liquid distribution pipe 8;

[0027] The liquid storage assembly 52 includes a liquid storage tank 521, which is fixedly connected to the box body 3. One side of the liquid storage tank 521 is connected to the first connecting pipe, and the other side of the liquid storage tank 521 is connected to a hose 522. The hose 522 is a high-temperature resistant plastic hose. One end of the hose 522 extends to the outside of the box body 3 and is connected to a connector 523. A sealing plug 524 is inserted on the connector 523. After the pump 51 is powered on and started, the liquid in the liquid storage tank 521 is extracted through the first connecting pipe, and the extracted liquid is introduced into the cross pipe 53 through the second connecting pipe. The liquid in the cross pipe 53 is released from the first water outlet pipe 54, and the released liquid falls on the door body 2 to cool the door body 2. When the liquid in the liquid storage tank 521 is replenished, the sealing plug 524 is removed, the water supply mechanism is connected to the connector 523, and the liquid is introduced into the liquid storage tank 521 through the hose 522, which is convenient for replenishing the liquid in the liquid storage tank 521.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
