Sprinkler head device for removal of smoke and toxic gas equipped with rotary venturi

A sprinkler head device for removal of smoke and toxic gas equipped with a rotary venturi, comprising:

• a nozzle configured to spray water supplied from the outside;
• a venturi casing configured to receive, through an inlet part thereof, the water sprayed from the nozzle to allow the same to pass therethrough in a state in which the venturi casing is rotatably supported by the nozzle, to generate negative pressure according to a Venturi effect while the water passes therethrough to suck ambient gas, and to mix the sucked gas with the water to discharge a mixture thereof;
• a rotary vane fixed to the inside of the venturi casing and configured to transmit rotational force to the venturi casing by means of kinetic energy received from water;
• and
• a press-fit vane positioned at an upstream end of the venturi casing and configured to draw in ambient gas and press the same into the venturi casing when the venturi casing rotates.
