[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. It is a fire separation with a certain fire resistance set in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of an ordinary door, a fire door also has the function of preventing the spread of fire and smoke, and can prevent the spread of fire within a certain period of time to ensure the evacuation of personnel.

[0003] For example, Chinese Patent with the publication number CN211598385U discloses a fast-heat-conducting heat-closing fire door, which belongs to the technical field of fire doors. The fast-heat-conducting heat-closing fire door includes a door frame. One outer wall of the door frame is fixed with a hinge by screws, and the other outer wall of the hinge is fixed with a door by screws. One outer wall of the door frame is fixed with a rubber strip by screws. The door frame and the rubber strip are both made of heat-resistant materials. One outer wall of the door frame is fixed with a door closer by screws, and the other end of the door closer is fixed to one outer wall of the door by screws. A handle is movably connected to one outer wall of the door. By setting the door closer, the door can be automatically closed after being opened. The rubber strip can be clamped between the door and the door frame when the door is closed, so that the door is more firmly closed without locking, and can prevent smoke from escaping through the gap. When it is necessary to escape quickly, the door can be opened without unlocking, reducing the escape time, so as to achieve the effect of safe use.

[0004] The technical solution recorded in this scheme is not convenient for spraying water on the fire on one side of the door body. When the environment on one side of the door body catches fire, the fire at the fire scene will continuously burn the door body, thus reducing the safety protection and fire prevention performance of the fire door.
