Dual-wave band quick-sprinkling type fire extinguisher

The utility model relates to a water sprinkling head device for fixedly extinguishing fire, particularly a dual-wave band quick-sprinkling type fire extinguisher and is composed of a pipe seat, a water separator, an infrared detector, an ultraviolet detector, a gradually opened blade, etc. The quick-sprinkling type fire extinguisher collects the infrared detection and the ultraviolet detection in integration, and the detectors and a circuit control part are arranged in the gradually opened blade and the water separator. The upper end of the quick-sprinkling type fire extinguisher is communicated with an electromagnetic valve and a fire extinguishing water supplying pipe net, and the quick-sprinkling type fire extinguisher is arranged between the 3 meter height to the 30 meter height. The sprinkling radius is 10 meters. When fire disaster occurs on the place which is provided with the dual-wave band quick-sprinkling type fire extinguisher, the dual-wave band detectors send out the electrical signal, and simultaneously, the electromagnetic valve and a fire extinguishing water pump are started to supply the water. After the water flow is sprinkled by the gradually opened blade, the water flow drops on a fire point in the raindrop way to rapidly extinguish the fire point, and simultaneously, the alarm is sent out.
