Fireball is a device used for extinguishing and controlling fires. It is usually a spherical or cylindrical container containing a chemical or gas mixture that produces a fire extinguishing effect when encountering flames.

The working principle of a fire extinguishing ball is that when a fire occurs, it will automatically activate and release its internal extinguishing agent. Once released, the fire extinguishing ball will quickly spread the extinguishing agent, forming a widely covered fire extinguishing area. This type of device typically has sensors or triggers that can automatically trigger based on the temperature, smoke, or other indicators of a fire.
