The fireproof window 1 enhances the heat insulation of the fireproof glass by arranging a transparent heat-insulating film, effectively isolates heat, avoids the spread of fire, and thus reduces the loss caused by fire.
[0022] The controller 14 is electrically connected to the temperature sensor 4 , and the controller 14 is electrically connected to the roller shutter motor 9 . The controller 14 is responsible for receiving signals and controlling the start and stop of the roller shutter motor 9 .
[0023] A handle 15 is fixedly connected to the window frame 2, a clamping groove 16 is provided on the fireproof window 1, and a window push plate 17 is arranged on the window frame 2. When no emergency fire occurs, the window closing push plate 17 is used to close the window.
