Description

[Technical Field]

[0001] This utility model relates to fan technology, and more particularly to a floor-standing double-layer oscillating fan. [Background Technology]

[0002] In existing technologies, fans are all structured with a single air blowing device, meaning that most fans have only one fan head. Due to structural limitations, they are only suitable for personal use and can only oscillate left and right. The air blowing area is limited, resulting in low air delivery efficiency. When multiple people need to be cooled by the fan, the fan cannot meet the comprehensive air delivery and heat dissipation requirements, and the fan cannot blow air to them simultaneously, resulting in an insignificant cooling effect.

[0003] Moreover, although existing fans use left and right oscillation to solve the problem of narrow air delivery angle, the limited amplitude and angle of the oscillation result in a gap in the air delivery process, and still cannot completely solve the problems of small air delivery range and short effective air delivery time for the human body.
