Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a simple water-based fire extinguisher. Background Art

[0002] Water-based fire extinguishers extinguish flames by releasing water or aqueous liquids. The high specific heat and heat of evaporation of water give it the ability to absorb heat and reduce the temperature of flames, thereby extinguishing fires. Water-based fire extinguishers are suitable for extinguishing various types of fires, including fires of combustible materials such as wood, paper, cloth, and plastic, but are not suitable for fires of oil and electrical equipment. Compared with chemical fire extinguishing agents, water-based fire extinguishers are generally more environmentally friendly because water is a natural resource that does not pollute the environment and is safe for the human body.

[0003] For example, the simplified water-based fire extinguisher with the patent number "CN210583423U" includes a fire extinguisher shell, a handle is fixedly installed in the middle of one side of the fire extinguisher shell, a block is fixedly installed at the bottom of the other side of the fire extinguisher shell, a nozzle is threadedly connected to one side of the top of the fire extinguisher shell through a threaded hole, a pressure gauge is fixedly installed on the other side of the top of the fire extinguisher shell, and the interior of the fire extinguisher shell is respectively provided with a first cavity, a second cavity and a third cavity, a first solenoid valve is fixedly installed inside the first through hole, a second solenoid valve is fixedly installed inside the second through hole, and a third solenoid valve is fixedly installed inside the third through hole. The simplified water-based fire extinguisher of the utility model is provided with the first cavity, the second cavity and the third cavity inside the fire extinguisher shell, which makes the water-based fire extinguisher not only suitable for extinguishing initial fires of solids or non-water-soluble liquids, but also for initial fires of books, precision instruments and household appliances.

[0004] However, in the prior art, the specifications of common water-based fire extinguishers are also different. For example, 2kg water-based fire extinguishers are generally used in homes, small offices, vehicles and other places; 4kg water-based fire extinguishers are often used in larger places such as commercial places, large offices, factories and workshops to extinguish medium-sized fires; 6kg water-based fire extinguishers are suitable for large commercial buildings, factories, warehouses and other large spaces to extinguish larger fires; and 9kg water-based fire extinguishers are commonly found in huge spaces such as large factories, storage and logistics centers to extinguish larger fires.

[0005] Water-based fire extinguishers are usually portable. For example, small and medium-sized fire extinguishers are more convenient to use portable ones. When using them, one hand usually holds the bottle and the other hand presses. For people with less strength, it is quite strenuous to continue this action for a long time. For example, it usually takes about one minute or even longer to spray a 4kg or 6kg water-based fire extinguisher. If the fire extinguishing range is large, the fire extinguishing duration will also be longer. The fire extinguishers need to hold the fire extinguisher and move it at any time, which will cause arm fatigue and the nozzle cannot be better aimed at the fire extinguishing position, thereby reducing the fire extinguishing effect.
