    Patent number: 9683579
    Abstract: A circulator includes a main body forming an air passage, an impeller, and a motor. The main body is cylindrical, in which a discharge port is formed at one end thereof, a suction port is formed at the other end thereof, and the air passage extending from the suction port to the discharge port is formed in the inside thereof. An orifice is provided annularly along an inner periphery of the air passage to locally narrow the air passage. An impeller is disposed in a part of the air passage having been narrowed by the orifice. A motor is connected to the impeller to rotate the impeller so that the air having been sucked from the suction port is blown from the discharge port.
