This technology is a water-based fire extinguishing system consisting of multiple hooks that attach to the rim of a toilet bowl, a tubular water container that fits along the inside of the bowl and trap to hold the standing water, and a door that opens and closes the opening at the trap end of the container. In the event of a fire, the container can be removed to use the stored water for immediate fire suppression.
A standard flush toilet uses about 10L of water per flush, with about 4L remaining in the bowl and trap to prevent odors and pests. While research into reducing toilet water usage has been active due to global water shortages, existing waterless portable toilets are impractical for standard use, and there have been few attempts to repurpose the standing water already present in toilets.
This technology divides the water container into a flexible ring-shaped primary receptor that adheres to the bowl, a flexible tubular secondary receptor that fits from the bottom of the bowl to the trap, and a rigid tertiary receptor that narrows toward the trap. The cover opens under flush pressure and closes via an elastic mechanism. Inserting the container releases the hook lock, while removing it seals the container to prevent spills. A cross-shaped wire cutter in the tertiary receptor prevents trap clogs. It is suitable for residential bathrooms, hotel rooms, and older buildings or small offices lacking fire extinguishers, allowing the standing water in the toilet to be used for initial fire suppression without needing separate water storage.
