Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a fan oscillation assembly and a fan. Background Technology

[0002] Taking a ceiling-mounted fan as an example, it has two motors. One motor is a blade motor, which drives the blades to rotate at high speed, and the other motor is an oscillating motor, which drives the blades to oscillate. For this purpose, a wire needs to be connected to the blade motor to supply power. In traditional technology, one end of the wire is connected to the blade motor and the other end is connected to the mains power, so that one end of the wire is stationary and the other end oscillates with the blade motor. This makes it easy for the wire to get tangled in other parts and be pulled during the oscillation, causing the fan to malfunction.

[0003] To solve the aforementioned technical problems, the inventors, through experimentation, discovered that conductive slip rings could be used for conductivity. There are two types of conductive slip rings: ① Carbon brush type conductive slip rings. Because of the carbon brushes, these slip rings experience continuous wear and tear during operation, resulting in carbon dust. Since fans contain motors with magnets, the presence and accumulation of carbon dust can lead to motor malfunctions. Furthermore, prolonged wear of the carbon brushes can also cause electrical connection failures. ② Conductive slip rings consisting of an inner ring, ball bearings, and an outer ring. Considering structural strength and other factors, copper cannot be used to make the inner ring, ball bearings, and outer ring; steel is generally used. However, steel has a much lower conductivity than copper, causing the conductive slip ring to occasionally exhibit excessively high contact resistance, leading to unstable motor operation. Additionally, conductive slip rings consisting of an inner ring, ball bearings, and an outer ring have more components, resulting in higher costs.

[0004] Therefore, it is necessary to improve and optimize the existing fan structure. Utility Model Content
