Abstract

A smoke exhaust nozzle is disclosed, which includes an assembly frame, a connecting element, blade-fan member, a flow guide member, and an assembly cover, wherein the smoke exhaust nozzle is assembled and located in an outlet of a fire hydrant. When the user opens the hydrant for use, water will impact the vortex piece of the blade-fan, the blade-fan is then driven by water to produce vortex motion. The water will pass through the atomizer element of the assembly cover after flowing through the blade-fan, so that the smoke exhaust nozzle will discharge the thick smoke out of the fire scene by means of the strong vortex generated by the blade-fan, and will cool down the fire scene and dilute the thick smoke by the ejected mist to increase the visibility of the fire scene, thereby accelerating the rescue.

Description

Smoke exhaust nozzle

The invention relates to a fire-fighting appliance, in particular to a smoke exhausting nozzle, which can effectively discharge smoke and use water mist to cool the site, thereby accelerating the work of disaster relief.

According to the general fire, it is caused by artificial arson and loss of accidents. Otherwise, it is the cause of electrical failure or old electric wire fire. When the fire occurs, if it can be fired in time, it will be glad; if not, it belongs to Flammable items are often out of control. They only escape quickly and wait for the fire truck to rush. However, after the fire, financial losses and casualties are often reported or reported. Occasionally, some firefighters Those who were injured in the fire and rescued were all accidents caused by bruises, coma or burns caused by high temperature under the smoke of five fingers.
