The impeller 200 rotates to rotate and squeeze the air to generate a flowing air current, and the air current is discharged from the scroll 300.

As shown in fig. 1-3, the fan assembly further includes an air duct 400, the air duct 400 is connected to the volute 100 corresponding to the volute 300, the air duct 400 is tangent to the impeller 200, and air is smoothly discharged through the arc-shaped surface of the volute 100. The air ducts 400 have two air ducts 400, each air duct 400 is adapted to the air outlets 500 which are independent of each other, and the air outlets 500 on each air duct 400 face the same direction. The air outlet 500 may be oriented in a radial direction of the impeller 200 or in an axial direction of the impeller 200. In the spatial direction, when the air duct 400 with a thinner vertical thickness needs to be obtained, the air outlet 500 is arranged towards one axial side of the impeller 200, and when the air duct 400 with a thinner transverse thickness needs to be obtained, the air outlet 500 is arranged towards one radial side of the impeller 200. In a scene such as a ceiling, the air outlet 500 is preferably disposed toward one axial side of the impeller 200.

The shape of the air outlet 500 of the air duct 400 may be any shape, such as a strip, a straight line, a curved line, and a broken line, and in this embodiment, it is preferably a straight line or a strip on the diameter line of the impeller 200. The number of the air outlets 500 may be one or more, and when there are a plurality of air outlets 500, the shape of the air outlet 500 may be one of a strip, a straight line, a curved line and a broken line, or a combination of any two or more.
