Problems solved by technology

[0003] Dry powder fire extinguishers are a relatively common fire extinguisher in daily life. Dry powder fire extinguishers are divided into three types: portable, backpack and cart according to the way they move. The most common type is portable fire extinguishers, which are placed in most buildings. For portable dry powder fire extinguishers, since dry powder fire extinguishers are forbidden to be placed most of the time, the dry powder inside is in a state of accumulation, so the dry powder in the fire extinguisher needs to be shaken to loosen before use, otherwise the dry powder in the fire extinguisher is not easy to spray out Or the amount of spray is small, but a certain amount of fire extinguishing time will be wasted when the fire extinguisher is shaken and loosened manually, which may miss the best fire extinguishing time

Abstract

The invention discloses a dry powder extinguisher, and belongs to the technical field of extinguishers. The dry powder fire extinguisher comprises a fire extinguisher body and a powder suction pipe, arectangular box is fixedly connected to the upper end of the fire extinguisher body, a hollow sleeve is rotationally connected to the inner top of the fire extinguisher body, the powder suction pipeis located in the hollow sleeve, a transverse plate is fixedly connected to the lower end of the hollow sleeve, a plurality of evenly distributed stirring rods are fixedly connected to the outer edgeof the lower end of the transverse plate, a driving device connected with the hollow sleeve is arranged in the rectangular box, a gas storage tank storing high-pressure gas is fixedly connected to thelower end of the fire extinguisher, and an auxiliary gas spraying device is arranged between the gas storage tank and the inner wall of the fire extinguisher. When the dry powder extinguisher is used, dry powder in the dry powder extinguisher can be stirred and blown away by pulling a pull ring, so that the dry powder is loosened more uniformly and quickly.

Description

technical field [0001] The invention relates to the technical field of fire extinguishers, in particular to a dry powder fire extinguisher. Background technique [0002] Dry powder fire extinguisher is a kind of fire extinguisher. According to the type of dry powder fire extinguisher, it can be divided into ordinary dry powder fire extinguisher and superfine dry powder fire extinguisher. The dry powder fire extinguisher is equipped with dry powder fire extinguishing agent such as ammonium phosphate salt. This dry powder fire extinguishing agent is easy to flow and dry. It is composed of inorganic salt and crushed and dried additives, which can effectively extinguish the initial fire. [0003] Dry powder fire extinguishers are a relatively common fire extinguisher in daily life. Dry powder fire extinguishers are divided into three types: portable, backpack and cart according to the way they move. The most common type is portable fire extinguishers, which are placed in most bu...
