Wherein, the wind dividing piece 3 can be a flat plate structure; the wind dividing member 3 may be of a curved structure, or may be of a partially curved structure, or may be of a flat plate structure, and may be of a wavy curved structure, or of an arcuate curved structure, and the cross section of the wind dividing member 3 may be curved, as shown in fig. 1 and 2, perpendicular to the axial direction X of the airflow generator 2, so that the wind dividing member 3 may have a flow guiding effect on the airflow when the wind dividing member 3 is provided with a curved structure, thereby facilitating the formation of an air curtain.
Specifically, the wind dividing member 3 may have a curved plate-like structure, or may have another curved structure. Referring to fig. 1 and 2, the wind dividing member 3 has an arc-shaped curved structure, which protrudes toward the inside or outside of the air curtain air duct 1.
