Under the action of the wind, each louver 132 can overcome the elastic force of the elastic member 140 to rotate and expand the angle between it and the air outlet 91, so as to realize the opening of the air outlet 91, so that the air flow can pass from the adjacent louvers 132. The space between is discharged. During this period, the elastic member 140 connected between the interlocking rod 1311 and the corresponding mounting rod 93 will be stretched and deformed by force, and the elastic force will be accumulated.

Conversely, when the fan 110 stops operating, that is, there is no wind, the linkage rod 1311 can drive the louvers 132 to rotate synchronously to the side of the air outlet 91 under the elastic force of the elastic members 140, so as to reduce the size of the louvers 132 and the air outlet 91. The included angle between them is achieved until the air outlet 91 is closed, especially the gap between the adjacent louvers 132 is closed. Based on this, dust protection can be achieved through each louver 132 to reduce the risk of impurities falling into the interior of the housing assembly 90 from the air outlet 91 .

In this way, each louver 132 can automatically switch between the states of “opening the air outlet 91” and “closing the air outlet 91” according to whether the air sterilizer, especially the fan 110, is operating. The motor and other structures are driven and controlled, so the structure is simple and the cost is low.
