Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the hand-held fire extinguisher of the present invention includes a fire extinguisher body, the fire extinguisher body includes a cylinder 1, the top of the cylinder 1 is provided with a barometer 2 and a push handle 3, and the top side of the cylinder 1 is provided with a spout 4, The nozzle 4 is connected with a spray hose 5, and the end of the spray hose 5 is provided with a nozzle 7-1.

[0034] The air pressure gauge 2 shows the pressure in the cylinder, press and hold the handle 3, the gas and fire extinguishing agent in the cylinder body 1 are sprayed out by the nozzle 7-1 after the spout 4 and the spray hose 5. The nozzle 7-1 is set in a tapered shape, which can increase the velocity of the gas and fire extinguishing agent flowing through the nozzle 7-1.

[0035] "Fire extinguisher body" is the main part of the existing fire extinguisher. The structure of the fire extinguisher body can also be replaced by existing other t...

Embodiment 2

[0042] On the basis of Embodiment 1, the top of the central rod 7-3 is set in a conical shape with a narrow top and a wide bottom to reduce the impact of the airflow on the central rod.

Embodiment 3

[0044] On the basis of Embodiment 1, the top surface of the side wall of the resonant cavity 7-2 is set as an inclined surface to reduce the impact of the air flow on the resonant cavity 7-2.

Abstract

The invention discloses a handheld fire extinguisher capable of eliminating fire smoke and belongs to the technical field of fire control and safety. The handheld fire extinguisher comprises a fire extinguisher body; a nozzle of the fire extinguisher body is connected with a jet hose, and the tail part of the jet hose is provided with a Hartmann whistle consisting of a spray nozzle, a central rodand a resonant cavity; a horn is arranged on the outer side of the tail of the jet hose; the spray nozzle is fixed at the tail end of the jet hose, the central rod is positioned in the middle of the spray nozzle and extends from the interior of the spray nozzle to the exterior of the spray nozzle, and the central rod is fixed through a plurality of supporting rods; and the bottom surface of the resonant cavity is fixedly connected with the bottom of the central rod. According to the handheld fire extinguisher capable of eliminating the fire smoke, the air flow in a cylinder body of the fire extinguisher can be used for extinguishing fire and also can be used for generating high-strength sound waves, and the high-strength sound waves can be subjected to sound wave agglomeration to eliminatethe fire smoke and prompt surrounding personnel a fire behavior and fire extinguishing personnel here, so that escape of personnel in a fire scene and rescue of personnel are facilitated. The fire smoke in a 3-5m<3> space can be eliminated quickly and efficiently, and a good smoke abatement effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection and safety, in particular to a hand-held fire extinguisher capable of eliminating fire smoke. Background technique [0002] Fire is one of the most frequent natural disasters, and its destructive power is extremely strong, which seriously threatens the safety of people's lives and properties. When a fire breaks out, a large amount of smoke is often produced. According to data, smoke is the most threatening to people in the fire scene, and the number of people killed by smoke accounts for about 80% of the total number of deaths. [0003] The main component of fire smoke is a mixture of combustion products and air, containing a large number of solid particles and liquid droplets mainly composed of carbon black, with a particle size range of 0.01 to 10 μm. A large amount of smoke generated during a fire has strong shading properties, which greatly reduces the visibility in the fire scene, ma...
