Fireproof door structure

Abstract

The invention discloses a fireproof door structure. The fireproof door structure comprises a door frame, a lintel and a door body, wherein the lintel is transversely erected on the door frame, and thedoor body is hinged to one side of the door frame; a transverse water storage cavity is formed in the lintel, multiple water outlets in an array are formed in the lower end face of the lintel in thelength direction, and plugs made of PE plastic are embedded in all the water outlets for closing the water outlets; a first water inlet pipe communicated with the water storage cavity is horizontallymounted on one side of the lintel, a first smog sensing switch is mounted on the first water inlet pipe for controlling the first water inlet pipe to be opened or closed after detecting indoor smog information, after the indoor temperature rises to 120 DEG C or above, the plugs automatically melt and soften, the water outlets are exposed, and water flows out from the water outlets and is poured onto the door body to cool the door body, so that water mist is formed to prevent the smog from entering gaps in the periphery of the door body. By adopting the technical scheme, the door body can be cooled automatically, the smog can be prevented from entering the door, and the survival probability of people can be effectively increased when a fire comes.

Benefits of technology

This patented design allows for easy access by users during fires or emergencies without having them feeling threatened due to smoking inside their houses. It also prevents harm caused by flames that may come over while trying to leave behind at home.

Problems solved by technology

This patents discusses how fires affecting humans may be caused by factors like harmful substances from burning flames (carbonmonia), chemical agents used for fighting fires (nitric acid) , and inflammation associated with smoking cigarettage. These causes include respiratory issues related to air pollution and occupational hazards during building construction. Additionally, there has been research showing that individuals who use firefight equipment often suffer severe injuries while trying to evacuate safely at home without causing significant injury themselves.
