Problems solved by technology

[0002] At present, commonly used fire extinguishers include foam fire extinguishers, water mist fire extinguishers, pressure handle dry powder fire extinguishers, etc., and can also be used to directly spray the fire source with a water pipe to extinguish the fire. The above fire extinguishing process needs to be operated in the fire field with fire extinguishing tools when a fire occurs, and the fire extinguishing speed is slow. The fire extinguishing effect is not obvious, and people and fire extinguishing tools must be close to the fire source at the same time during operation, which brings hidden dangers to the life safety of fire extinguishers
[0003] Moreover, the fire extinguishing effect of the fire extinguishing agent added in the existing fire extinguisher is not ideal, and some fire extinguishing agents also play a combustion-supporting effect after failure, which further affects the fire extinguishing effect

Embodiment 1

[0030] A spherical explosive dry powder fire extinguisher, such as figure 1 and figure 2 As shown, the spherical explosive dry powder fire extinguisher includes a spherical shell 1 and a dry powder fire extinguishing agent 2 filled in the spherical shell 1. The center of the spherical shell 1 is provided with an explosive package 3 and a device for controlling the explosion of the explosive package 3. The ignition device, the spherical housing 1 is composed of two hemispherical housings; the ignition device is a remote ignition device 4 arranged in the spherical housing 1 .

Embodiment 2

[0032] A spherical explosive dry powder fire extinguisher, such as image 3 and 4 As shown, the difference between this spherical explosive dry powder fire extinguisher and Embodiment 1 is that the ignition device also includes a temperature-controlled fuse 5 arranged outside the spherical casing 1 and connected to the explosive package 3 through a lead wire; the spherical casing 1 is made of 1.2mm thick coated paper.

Embodiment 3

[0034] A spherical explosive dry powder fire extinguisher, such as Figure 5 As shown, the difference between the spherical explosive dry powder fire extinguisher and the embodiment 2 is that the outer surface of the spherical shell 1 is provided with a remote control roller 6, and the movement of the remote control roller 6 is controlled by an external remote controller.

Abstract

The invention relates to a spherical explosive powder fire extinguisher, comprising a spherical shell and a dry powder extinguishing agent, wherein the spherical shell is filled with the dry powder extinguishing agent; a satchel charge and an ignition device are arranged at the center of the spherical shell; the ignition device is used for controlling detonation of the satchel charge; the spherical shell is composed of two semispherical shells; the ignition device preferably is a remote control ignition device which is arranged at the center position of the spherical shell, or a temperature control blasting fuse which is arranged out of the spherical shell and is connected with the satchel charge through a lead; the shell and the internal dry powder extinguishing agent are simultaneously exploded by the explosive force which is generated after the satchel charge in the fire extinguisher explodes; the dry powder extinguishing agent is evenly sprayed on a comburant in a fire, so as to put out the fire; an impact wave generated in explosion also plays a fire-extinguishing role; and the fire-extinguishing effect is significant.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a spherical explosive dry powder fire extinguisher. Background technique [0002] At present, commonly used fire extinguishers include foam fire extinguishers, water mist fire extinguishers, pressure handle type dry powder fire extinguishers, etc., and can also be used to directly spray the fire source with a water pipe to extinguish the fire. The above fire extinguishing process needs to be operated in the fire field with fire extinguishing tools when a fire occurs, and the fire extinguishing speed is slow. The fire extinguishing effect is not obvious, and people and fire extinguishing tools must be close to the fire source simultaneously during operation, which brings hidden dangers to the life safety of fire extinguishers. [0003] And the fire extinguishing effect of the fire extinguishing agent added in the existing fire extinguisher is not ideal, and some fire extinguishing agents als...
