Abstract

This invention provides a household fire extinguisher and its usage method, aiming to solve the problems of existing household fire extinguishers, such as complex operation, inconvenient access, and unsafe power-off logic. The device includes an outer casing, a removable battery, a DC motor, a centrifugal pump, a high-pressure water hose, a dual-function nozzle, and a linkage switch. The outer casing is hinged to a cabinet door with a push-to-open hinge structure for easy door opening. The casing contains a status indicator light and an alarm for safety alerts. The nozzle is attached to the cabinet door; opening the door triggers the switch, automatically activating the water pump circuit for rapid start-up. The high-pressure water hose is stored in an anti-tangling, stacked manner. The nozzle assembly includes a direct-fire nozzle and a crescent-shaped diffuser nozzle, which can be used for fire extinguishing and generating a protective water curtain, respectively. This invention features a compact structure, rapid start-up, and enhanced safety.
