US 10,478,647 B2 · Stovetop fire suppressor with shuttle actuator and method

Abstract

An automatic stovetop fire suppressor is activated by a shuttle actuator. The self-contained and closed container device provides a gradual release of a fire suppressing agent in a desired distribution pattern. A method of reliable and spatial agent release are provided herein. A plastic cone shaped lid seals on the bottom of a can and forms a closed container. The closed container is filled with a fire suppressing agent. An initiator charge is housed external to the container of fire suppressing agent and is fuse activated. The activated charge displaces the shuttle. As the shuttle displaces, vertical support for the bottom cone lid is removed and a compression spring breaks a circumferential seal between the bottom lid and container cylindrical sidewall and lowers the bottom lid exposing a radial opening. Fire suppressing agent flows out of the radial opening, suppressing a stovetop fire.
