Description

Technical Field

[0001] This utility model relates to the field of electrical transmission equipment technology, specifically a fan oscillation and steering transmission structure. Background Technology

[0002] Fans are extremely common electrical appliances in daily life. They can promote air circulation and achieve concentrated and rapid air delivery, which can improve people's comfort and cool equipment. Some fans also have an oscillation function to increase their air delivery range.

[0003] Currently available fans are mostly fixed or oscillating models. The oscillating fans are basically a single fixed connection that cannot be disassembled. They take up more space when the rotation is not needed. On the other hand, single fans do not have a rotation function and can only deliver air in a fixed straight line, which is less flexible and functional.

[0004] To address the aforementioned issues, we have made improvements by proposing a fan oscillation steering transmission structure. Utility Model Content
