摘要： A blower, including: a volute including air inlets and an air outlet; a wind wheel disposed in the volute; and air collectors. Each air collector includes a curved air guide. The air inlets are disposed at two sides of the wind wheel, respectively. The air collectors correspond to the air inlets. The curved air guide extends into the volute, and the inner diameter of the curved air guide decreases stepwise. The relationship between a minimum inner diameter D0 of the curved air guide and an inner diameter D1, an outer diameter D2 of the wind wheel fulfills the following formula: D1+⅓(D2−D1)≤D0≤D1+⅔(D2−D1). An exhaust fan that includes the blower is also provided.

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.
