Fire control is to eliminate and prevent potential safety hazards through various equipment and human intervention modes, and is an important work for social life stability, and in different scenes, different fire control equipment is needed, for example, civil equipment such as fireproof doors or fire control lamps are needed in buildings. When a fire disaster happens, the fireproof door plays a great role, the existing fireproof door is difficult to treat thick smoke, difficulty is increased for people to evacuate and escape, the function of the fireproof door is greatly reduced, and the fireproof door is inconvenient to use. The surface is smooth, namely the surface of the fireproof door is not hollowed out, and a complete fireproof plate is adopted.

At present, the existing flat and smooth fireproof door (such as patent number: CN 215718293U) discloses a fire-fighting fireproof door, and relates to the technical field of fire control, including fireproof door body, first space has been seted up to the inside of fireproof door body, the upper surface fixedly connected with of diapire in the first space a plurality of equidistance square barrels of arranging, every the front of square barrel is all fixed to be linked together has four smoke extraction pipes that the equidistance was arranged, and every smoke extraction pipe is all fixedly inlayed with fireproof door body, the upper surface fixedly connected with hollow lid of fireproof door body, the second space has been seted up to the inside of fireproof door body. This fire control is with preventing fire door can make first fender dish open through setting up the air exhauster to make the dense smoke take out from the smoking pipe, can effectively avoid the dust to get into inside the smoking pipe through setting up the filter screen, through setting up the breather pipe, can be favorable to the breather pipe blowout wind when starting the hair-dryer, thereby be favorable to personnel's evacuation to flee.

However, in the implementation process of the technical scheme, at least the following technical problems are found:

the ventilation structure is suitable for poor: when the existing fireproof door is used, because smoke dust does not pass through the fireproof door in order to ensure that the fire does not occur, a complete plate is often used as a door plate so as to separate a fire source, but when no fire occurs, air cannot pass through the fireproof door, and the air transmission is affected; and prevent fire door with ventilation effect when using, if meet the conflagration, the through-hole that the smoke and dust directly can follow the fire door surface passes, leads to preventing that fire door can't play the effect of isolated smoke and dust, seriously influences the normal use of preventing fire door, for this reason, we propose a fire door that the surface is level and smooth.
