An automatic fire extinguishing device for auto-ignition

Abstract

The invention discloses an automatic fire extinguishing device for spontaneous combustion of an automobile. The automatic fire extinguishing device comprises a shell, a high-pressure gas cylinder, blasting equipment and a metal hose, wherein an inner cavity of the shell is filled with dry powder, and two ends of the shell are provided with openings; the high-pressure gas cylinder is arranged in the cavity of the shell and is filled with high-pressure gas; the blasting equipment is respectively and fixedly connected with the opening at the top end of the shell and the top end of the high-pressure gas cylinder; the metal hose is fixedly connected with the opening at the bottom end of the shell; the top of the high-pressure gas cylinder is provided with a working diaphragm; the blasting equipment comprises a firing pin device fixedly connected to the top end of the high-pressure gas cylinder and a temperature initiation device connected with the firing pin device. The blasting equipment of the automatic fire extinguishing device is composed of the firing pin device and the temperature initiation device, the temperature initiation device is internally provided with an expansion thermometer which is used for detecting outside temperature according to a temperature wrap to push and pull the firing pin device, and the high-pressure gas cylinder is pierced by the firing pin device so that the fire is extinguished. The fire extinguishing device is automatically controlled to open or close by means of temperature and is not needed to be pressed with hand so as to be very intelligent and convenient in fire extinguishing.

Description

technical field [0001] The invention relates to fire extinguishing equipment, in particular to an automatic fire extinguishing device for automobile spontaneous combustion. Background technique [0002] With the gradual improvement of living standards, cars are more and more integrated into our daily life, bringing a lot of convenience and fun to people's lives, but sometimes they can also become dangerous potential killers, such as cars spontaneously igniting or catching fire after a collision. It is the engine part of the nose that is prone to fire. The current car fire extinguishing devices usually need to be turned on manually. When the car spontaneously ignites, female drivers and novice drivers can easily escape from the car due to panic and forget to press the car fire extinguishing device, causing the car to spontaneously ignite and even explode. Manual car fire extinguishing devices Very limited in scope and usefulness. [0003] Therefore, how to design an automat...
