Description

Technical Field

[0001] The utility model relates to the technical field of desktop fans, in particular to a desktop fan capable of multi-speed angle adjustment. Background Art

[0002] Desktop fans, as the name implies, are small fans placed on a flat surface such as a desktop, mainly used to provide local cooling and air flow. They are usually small in size and lightweight, making it easy for users to move or place them in any suitable location when needed.

[0003] Many desktop fans can only swing left and right, and do not have the function of adjusting the pitch angle. The adjustment of the pitch angle means that the head of the fan can be moved up and down to change the angle and height of the air supply. When the fan only supports left and right swing, its air supply range is relatively fixed, and it may not effectively cover certain areas that need to be cooled, such as the user's upper body or specific work areas. Users may need to frequently adjust the position of the fan or their body posture to obtain a more comfortable air supply effect, which not only reduces the user experience, but may also affect the user's work efficiency or rest quality.
