Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishers, in particular to a battery-powered water-based fire extinguisher. Background Art

[0002] Water-based fire extinguishers are suitable for extinguishing flammable solids or non-water-soluble liquids. They are fire extinguishers that can extinguish fires of live electrical equipment. After spraying, they become water mist, which can evaporate a large amount of heat from the fire scene and quickly reduce the temperature inside the fire scene. The surface active agent quickly forms a layer of water film on the surface of the burning object, which plays a dual role of isolating oxygen, cooling, and isolating. It is an essential firefighting equipment for preventing fires and protecting lives and property. Existing water-based fire extinguishers require users to keep pressing the handle with their hands to spray the active agent. Once the hand is released, the brake will pop up to notify the work.

[0003] The currently existing water-based fire extinguishers need to be close to the burning object and spray continuously at the root. In the event of a lithium battery fire, it cannot be extinguished in a short time. Not only is the surrounding temperature high, but it will also produce a large amount of harmful gases, making it difficult to get close to the root for continuous spraying. In addition, when using a fire extinguisher, there are often elderly people or children who are unable to lift the fire extinguisher to continuously spray the lithium battery due to their weak strength, making it inconvenient to use.
