Description

Technical Field

[0001] The utility model relates to the technical field related to ultra-low temperature fire extinguishers, in particular to an ultra-low temperature fire extinguisher. Background Art

[0002] Fire extinguishing agent refers to a substance that can effectively destroy combustion conditions and terminate combustion. Fire extinguishing foam is a group of small bubbles surrounded by liquid on the surface, with a specific gravity between 0.001 and 0.5. Since the specific gravity of foam is much smaller than that of general flammable liquids, it can float on the surface of the liquid and form a foam covering layer.

[0003] For example, Chinese patent CN219539313U discloses a low-temperature water-based fire extinguishing agent storage mechanism, including a water-based fire extinguisher body, wherein a cavity is fixedly installed at the bottom of the inner cavity of the water-based fire extinguisher body. When in use, through the connection structure, the downward pressure structure and the stirring structure, when the external temperature reaches ℃, the temperature sensor is sensed, and the waterproof micro-motor is started to rotate the transmission rod, so that the connecting plate can be moved, and when the pressing plate moves to the top, the pressing plate is pressed to the agent bag, so that the low-temperature refrigerant inside the agent bag can be sprayed out, and then sprayed into the interior of the water-based fire extinguisher body through the outlet, and then through the displacement of the inclined rod, and then through the rotation of the first worm gear and the second turbine, the transmission plate can be rotated by the meshing of the two, and then the stirring wheel is rotated, so that the agent can be fully stirred evenly to avoid affecting the use effect due to excessively high external temperature. However, it can only be applied to water-based fire extinguishing agents, and it is not applicable to the situation where the rubber plug and rubber tube fail due to the ultra-low temperature during the use of dry powder fire extinguishing agents.
