Abstract
A thermo-controlled self-explosive fire extinguisher, which comprises a flat, rounded container having an outer thread around the periphery, a container holder having a bottom opening and an inner thread inside the bottom opening, and a fire extinguishing agent filled in the container. After installation of the container holder in a round hole on a board at the ceiling, the outer thread of the container is threaded into the inner thread inside the container holder and disposed substantially in flush with the ceiling. The fire extinguishing agent expands when hot, and the container body explodes when its inside pressure surpasses a predetermined level, causing the fire extinguishing agent to be spread out widely.
