[0052] Optionally, the insertion portion 11 is a buckle.

[0053] Preferably, the wind sweeping blade bodies 20 of two adjacent wind sweeping structures 1 rotate in opposite directions relative to their respective rotating shafts, so that the free ends 200 of the two adjacent wind sweeping blade bodies 20 are oriented in different directions, and multiple wind sweeping structures 1 are arranged at intervals so that the airflow is blown out from the free ends 200 in different directions, thereby expanding the air outlet range.

[0054] Preferably, along a predetermined direction, the rotation directions of the wind sweeping blade bodies 20 of two adjacent wind sweeping structures 1 are opposite relative to their respective rotating shafts, so that the free ends 200 of the two adjacent wind sweeping blade bodies 20 are in opposite directions, that is, the rotation angles of the wind sweeping blade bodies 20 of the two adjacent wind sweeping structures 1 differ by 180 degrees, so that the airflow has air outlets in both the upper and lower directions in the vertical direction, thereby maximizing the air outlet range of the airflow in the vertical direction.

At this time, when the air flow is discharged, the overall air flow speed is reduced, and the wind feeling is weak. At this time, the air flow flows out from the gap and passes through the spiral leading edge 21 of the spiral sheet (wind sweeping blade body 20), flows along the spiral profile of the wind sweeping blade body 20, and flows through the spiral trailing edge 22 and then flows out from the free end 200. The air flow continuously flows out to the free end 200 of the spiral sheet (wind sweeping blade body 20) according to the wall-adhering effect, which can not only achieve the spiral disturbance effect of the air flow, but also make part of the air flow flow along the spiral profile direction of the wind sweeping structure 1, thereby increasing the air supply range.

[0063] Specifically, when the wind outlet mode is the sweeping wind mode, the sweeping wind control method includes: driving the sweeping wind blade body 20 of each sweeping wind structure 1 to rotate around the rotating shaft 100 of the sweeping wind structure 1, and controlling two adjacent sweeping wind blade bodies 20 to rotate relative to their corresponding rotating shafts 100 in different rotation directions and / or rotation speeds.
