Furthermore, two mounting plates which are symmetrical left and right are arranged inside the upper shell 1; the two mounting plates are respectively a driving piece mounting plate 151 and a button mounting plate 152; the swing driver 12 is mounted on the driver mounting plate 151; the volute 112 is rotatably mounted between the two mounting plates. As shown in fig. 8, the swing driver 12 is mounted on the driver mounting plate 151; the volute 112 is located between the two mounting plates, and extends horizontally outwards through the rotation, and is arranged on the mounting plates in a penetrating manner, so that the rotation connection between the volute 112 and the two mounting plates is realized. Therefore, the swing driving element 12 drives the volute 112 to rotate between the two installations through the mutual engagement between the first gear 1200 and the limit gear 1122, so that the fan device realizes swinging air outlet in a vertical plane.
