Description

Technical Field

[0001] The utility model relates to a fan, in particular to a multi-angle rotating fan. Background Art

[0002] The use of fans is very wide. Although current fans can rotate back and forth automatically, the rotation angle range cannot achieve 360-degree rotation, that is, the rotation angle is limited, and users can only be blown by the wind within the rotation range; in addition, current fans are also used for air circulation in large air-conditioned rooms, such as office workstations. When there are many users, especially in large spaces, this fan with limited angle rotation is not able to meet the needs of multiple users at fixed workstations. Although multiple fans can be set up for use together, this is also done when there is no choice. Utility Model Content
