[0007] The wind guide assembly includes a rotating rod shaft and a wind shield, which is placed in the air outlet housing and is in contact with the air duct to block the air flow from being discharged out of the air outlet housing; the rotating rod shaft extends into the air outlet housing and is connected to the wind shield, which is driven by the rotating rod shaft to change its position of blocking the air duct.

[0008] Preferably, the rotating rod shaft is provided with an annular groove, and the diameter of the annular groove of the rotating rod shaft corresponds to the diameter of the through hole, so that the through hole and the annular groove are connected to limit the position of the rotating rod shaft; the end of the rotating rod shaft is inserted into the air outlet cover shell from the through hole, and the head end of the rotating rod shaft is exposed outside the air outlet cover shell.

[0009] Preferably, a knob portion is provided at the head end of the rotating rod shaft, and an edge of the knob portion is provided with anti-slip stripes.

[0010] Preferably, the air duct is provided with an L-shaped retaining edge extending therefrom, and the wind shield is embedded in the retaining edge so as to utilize the retaining edge to restrict the wind shield from leaving the air duct.

[0011] Preferably, the rotating rod shaft is L-shaped as a whole.

[0012] Compared with the background technology, the utility model has the following beneficial effects:

[0013] The utility model proposes an air duct structure with adjustable wind direction for an air purifier. The air duct of the air outlet housing of the structure is arranged in a circular pattern, which can realize wide-angle air outlet. To control the air outlet direction, the air outlet housing is equipped with an air guide assembly, which includes a rotating rod shaft and a wind shield. The wind shield can be driven to move in close contact with the air outlet housing by twisting the rotating rod shaft. The wind shield can be used to block the partial air duct of the air outlet housing to realize the control of the air outlet direction. It has the advantages of simple structure, compact fit, and reasonable design. Therefore, it is a product with superior performance in both technical and economic aspects.
