A gas-powder mixing device for fire extinguishers

Abstract

The invention provides a gas powder agitating device for a fire extinguisher. The gas powder agitating device comprises a closed bottle body, a bottle air inlet opening, a bottle air outlet opening, a hollow agitating pipe and a hollow siphon pipe, wherein the bottle air inlet opening and the bottle air outlet opening are arranged at the upper end of the bottle body; and the hollow agitating pipe and the hollow siphon pipe are located in the bottle body and are arranged along the axial direction of the bottle body. The upper end of the agitating pipe penetrates through the bottle air inlet opening to stretch out of the bottle body; the upper end opening of the agitating pipe is used for introducing an opening section of high-pressure gas; a pipe body of the agitating pipe has a plurality of rows of air exhausting holes; upper and lower end openings of the siphon pipe are opening ends; an air inlet at the bottom of the siphon pipe is in a tapered structure; and the upper end of the siphon pipe penetrates through the bottle air outlet opening to stretch out of the bottle body, so as to conveniently spray mixed and agitated dry powder by the high-pressure gas, and the fire extinguishing effect is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of civil fire-fighting tools, and in particular relates to a gas-powder stirring device for a fire extinguisher. Background technique [0002] Our country is a country with frequent fires. Every year, fires cause huge personal and property losses to the country and the people. The traditional dry powder fire extinguishers that are currently popular in the market, if left for a long time, the dry powder inside may agglomerate or accumulate on the The bottom of the bottle body, so that some dry powder cannot be effectively sprayed out during the fire extinguishing and powder spraying operation, making the fire extinguishing effect not ideal. Even a new fire extinguisher is difficult to achieve sufficient pressure gas and dry powder due to its simple structure. When mixing and stirring, there will also be dead angles, making it difficult for the dry powder to be sprayed out evenly, thereby reducing the fire ext...

[0002] Our country is a country with frequent fires. Every year, fires cause huge personal and property losses to the country and the people.

Even a new fire extinguisher is difficult to achieve sufficient pressure gas and dry powder due to its simple structure.
