Fire escaping room

Claim 1

A fire-escaping room comprising: several vertical room walls, a floor and a roof constructed by fire-proof material and together defining said fire-escaping room; a metal door frame firmly disposed on one of said vertical room walls, said door frame having an inner peripherial surface formed with an inward perpendicularly projecting step portion into which a continuous frame-shaped sealing member being inserted; a horizontally openable fire-proof door hinged to said door frame and serving as an only entrance/exit of said fire-escaping room whereby when closed, said fire-proof door airtightly abuts against said frame-shaped sealing member to form a completely closed space, said fire-proof door including a metal outer casing and an inner compartmentalizing board which together define an upper chamber and a lower chamber, said upper chamber being filled up with a thermally insulating layer, said lower chamber being formed with several vent holes for ventilating said fire-escaping room, said fire-proof door further including a manually operated slide block set located in said lower chamber, said slide block set being operable inside said fire-escaping room to slide between a first vent hole-closing position and a second vent hole-opening position; a manually operated air pump embedded in one of said vertical room walls, including a housing having an open end, an elastic soft wovable diaphragm sealedly covering said open end, a manually operated pull button fixedly mounted on said movable diaphragm, an inlet formed on a lower portion of said housing and communicated with a ventilating pipe extending externally, an outlet formed on an upper portion of said housing and communicated with a discharging pipe extending into said fire-escaping room, a first steel ball placed on said inlet to block said inlet and a second steel ball placed on said outlet to block said outlet, said housing and movable diaphragm together defining an air chamber whereby by means of repeatedly pulling/pushing said pull button disposed on said movable diaphragm, the volume of said air chamber is changed to suck external air through said ventilating pipe into said air chamber and then the air in said air chamber is compressed to discharge from said discharging pipe into said fire-escaping room intermittently; an endless sprinkling pipe disposed around said vertical room walls, said sprinkling pipe being formed with a plurality of sprinkling holes and connected with a water supply incoming pipe by a connecting pipe, a manually operated controlling valve being disposed on said connecting pipe to conduct/interrupt the water flow whereby when said controlling valve is located at a water flow conducting position, the water supplied from said incoming pipe flows into said sprinkling pipe to be sprinkled onto said vertical room walls and said floor; and a draining hole formed on said floor.
