摘要： An induced draft fan, including a volute including a chamber and an air discharge pipe; and a wind wheel disposed in the chamber of the volute. The wind wheel is connected to and operationally driven by a rotation shaft of a motor. The air discharge pipe is disposed on one side of the volute, and includes an inner pipe and an outer pipe surrounding the inner pipe. The inner pipe of the air discharge pipe communicates with the chamber, to form an air discharge passage. An annular groove is disposed between the inner pipe and the outer pipe; and the outer end of the outer pipe is provided with a curved groove, the curved groove extends axially and circumferentially to divide the outer pipe into a fixed part and a flexible part.

摘要： An induced draft fan, including: a housing, a wind wheel, an AC motor, and a controller. The controller includes: an AC-DC conversion circuit, a microprocessor, a Hall sensor, a drive circuit, and a relay. The input end of the AC-DC conversion circuit is connected to an external AC input, and the output end of the AC-DC conversion circuit supplies a DC current to each circuit part. The input end of the relay is connected to the external AC input, and the output end of the relay supplies power for corresponding parts. A magnetic ring is disposed on a rotating shaft of the AC motor. The Hall sensor is disposed close to the magnetic ring for detecting a signal of a rotational speed of the AC motor and inputting the signal of the rotational speed into the microprocessor. The microprocessor controls energization or deenergization of the relay.

摘要： A windmill, including a first end plate, a second end plate, and a plurality of primary blades disposed between the first end plate and the second end plate. The first end plate includes a central part provided with a base connected to a motor shaft. The second end plate includes a central part provided with an air inlet; the space between every two adjacent blades forms an air channel. The plurality of primary blades each includes an outmost end with respect to the central part of the first end plate, and the outmost end extends out of an outer edge of the second end plate. The connection line of every two adjacent outmost ends of the plurality of primary blades forms a circle, and the diameter D1 of the circle is larger than the diameter D2 of the second end plate.
