Fire extinguisher dry powder intelligent time domain injector

Abstract

The invention discloses an intelligent time-domain ejector for dry powder of a fire extinguisher and belongs to the field of fire-fighting equipment. The intelligent time-domain ejector for dry powder of the fire extinguisher comprises a starting assembly and a container body assembly; the container body assembly comprises at least two spaced cavities; spraying holes in a shell of the container body assembly communicate with the cavities; each cavity is internally provided with a gas generator; the starting assembly is connected with the gas generators of the cavities; and the gas generators in the cavities are sequentially started in sequence by the starting assembly to generate gas to be sprayed from the spraying holes. The split type container body assembly is adopted as an ejector body, the starting assembly is used for time-domain gas flow control, the gas generators in the cavities are sequentially started in sequence by the starting assembly to generate gas, dry powder extinguishing agents preloaded in the fire extinguisher are instantly and orderly sprayed, the center of flames is subjected to high-pressure blowing-spraying for instant flame extinguishing at first, then the periphery of the flames is covered and isolated to prevent burning back, and accordingly the purpose of instantly, efficiently and completely extinguishing fire is achieved, and the fire extinguishing reliability is ensured.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a dry powder intelligent time domain injector for fire extinguishers. Background technique [0002] Technically speaking, the ejector used in fire fighting equipment integrates high-tech in machinery, electronics, chemical industry, etc. It is a device that can release a large amount of gas in a short time to meet different needs. The dry powder fire extinguisher is used together, and the dry powder is blown out of the fire extinguisher by the expansion gas generated by the injector in a short time, so as to achieve the purpose of extinguishing the fire. [0003] At present, most fire extinguishers have certain defects in the timely detection and response of the initial fire source. Generally, after the fire occurs, the fire is extinguished by manual control. The speed of dry powder spraying is slow, and the instant fire extinguishing effect cannot be achieved, resulting in...

Problems solved by technology

[0003] At present, most fire extinguishers have certain defects in the timely detection and response of the initial fire source. Generally, after the fire occurs, the fire is extinguished by manual control. The speed of dry powder spraying is slow, and the instant fire extinguishing effect cannot be achieved, resulting in a large amount of property loss. ; There are also some intelligent fire extinguishing equipment, which can start the fire extinguisher by detecting the flame or temperature, and spray the dry powder out of the fire through the injector, but almost all of these fire extinguishers spray all the dry powder at one time, because the flame will generate high-temperature airflow , the sprayed dry powder is easily blown away and cannot achieve a stable fire extinguishing effect
