Description

Technical Field

[0001] The utility model relates to the technical field of portable fire extinguishers, in particular to a lithium battery portable water mist fire extinguisher. Background Art

[0002] A fire extinguisher is a portable firefighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are common firefighting equipment and are stored in public places or areas where fires may occur. Different types of fire extinguishers contain different ingredients and are designed to address different fire causes. Care must be taken when using them to avoid adverse effects and potential dangers.

[0003] A portable fire extinguisher is a lightweight, easy-to-use firefighting tool widely used in daily life and the workplace. Its main components include a cylinder for holding the extinguishing agent; a valve and other components in the head to control the release of the extinguishing agent; and a nozzle to direct the extinguishing agent toward the fire area. To use, pick up the extinguisher, rush to the fire scene, remove the safety pin, hold the nozzle tip, press the pressure handle, and aim the nozzle at the base of the flames to extinguish the fire. Advantages of portable fire extinguishers: They are highly maneuverable and can be quickly moved to the fire scene. They are relatively simple to operate and can be mastered with minimal training. They can effectively control fires in their early stages.

[0004] Fine water mist fire extinguishers mainly use water as the extinguishing agent, which is pollution-free to the environment and will not cause harm to the human body. Before using a portable fire extinguisher, compressed air needs to be added to the fire extinguisher tank to improve the fire extinguishing efficiency of the fire extinguisher. However, when the equipment is not used for a long time, the compressed gas in the tank will gradually leak out, reducing the pressure in the tank, causing the portable fire extinguisher to be returned to the factory for pressurization regularly to ensure the normal operation of the fire extinguisher. The pressurization process is complicated and tedious. At the same time, after the fine water mist fire extinguisher is used, the fire extinguishing agent in it needs to be re-added. The fire extinguishing agent addition process is relatively complicated, and manual addition cannot accurately control the amount of addition, which can easily lead to poor use of the fire extinguisher in the later stage.
