Abstract

A multifunctional portable handheld fire extinguisher includes a housing with a main body and an extension; a hand grip foldably connected to the extension via a folding button; a control circuit board housed within the main body; a drive motor housed within the main body and electrically connected to the control circuit board; a torque ratio gear set connected to and driven by the drive motor; an electric pump connected to the torque ratio gear set; a liquid inlet connected to the electric pump and exposed outside the main body; and a liquid outlet connected to the electric pump and exposed at a front end of the main body. This design replaces bulky, fixed, large-capacity fire extinguishing agents and nitrogen fire cylinders, eliminating limitations imposed by wiring and piping, and allowing for free-flowing fire extinguishing.
