[0025] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0026] See also Figure 1-3 , the utility model provides a technical solution.

[0027] Embodiment 1:

[0028] Please refer to the attached Figure 1-3 , in the specific implementation process: a smoke exhaust heat insulation fire door, comprising: a door frame 1, a door panel body 2 and an auxiliary structure; the auxiliary structure is installed on the door panel, and the door panel is installed on the door frame 1;

[0029] The auxiliary structure includes: a heat insulation component and a smoke exhaust component;

[0030] The heat insulation component is installed on the door panel body 2, and the smoke exhaust component is installed on the door panel body 2;

[0031] It should be noted that the door panel has a basic metal material structure, which makes the door panel have better thermal conductivity. A high-temperature resistant layer 5 made of asbestos mesh is arranged on the outer side of the substrate 3 to protect the substrate 3 from deformation caused by excessive heat. At the same time, a flame retardant layer 4 is arranged outside the high-temperature resistant layer 5 to prevent the high-temperature resistant layer 5 from catching fire and causing failure. A wear-resistant layer 6 is arranged outside the flame retardant layer 4 to protect the flame retardant layer 4 and prevent the flame retardant layer 4 from being scratched by daily wear and tear and causing the flame retardant layer 4 to lose its function. When a fire occurs, the door panel is used to protect the external high-temperature fire. The metal substrate 3 has good thermal conductivity, so that the heat of the door panel can be dissipated to the air faster, preventing the door panel from being deformed due to high temperature.

[0032] When a fire occurs outside, the temperature of the door panel will rise rapidly, which may cause insufficient heat dissipation of the door panel. Therefore, a spiral water pipe 7 is provided in the base plate 3 of the door panel. Since the specific heat capacity in the water pipe 7 is large, it can absorb more heat, and at the same time, the temperature of the door panel will not rise rapidly, so that the heat insulation effect of the door panel is better. When replenishing or injecting water into the water pipe 7, the personnel manually rotate the cover plate 9 on the water inlet 8 installed on the water pipe 7 in the door panel, unscrew the cover plate 9 through the thread, and expose the water inlet 8. The personnel inject water into the water inlet 8, and then inject or replenish water into the water pipe 7, which is convenient for the personnel to operate;

[0033] After a fire occurs outside, a certain amount of toxic smoke will be generated when the fire burns. By starting the exhaust fan 10 installed on the door frame 1, the smoke is sucked into the connecting pipe 11, and the smoke is preliminarily filtered through the filter 12 on the connecting pipe 11 to prevent the smoke from clogging the connecting pipe 11. After the smoke enters the connecting pipe 11, it enters the exhaust fan 10 and is guided and discharged through the exhaust pipe on the exhaust fan 10 to prevent the people inside from inhaling the smoke and causing danger.

[0034] It should be noted that the base plate 3 is made of metal, which makes the door panel more impact-resistant. The cover plate 9 is connected to the water inlet 8 by threads, which is convenient for personnel to open the cover plate 9 to add water inside; the exhaust fan 10 is provided with an exhaust pipe to facilitate guiding the smoke out of the room.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
