Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to a rotating mechanism and a fan with the rotating mechanism. Background Art

[0002] In modern home and office environments, fans are common ventilation equipment, and the optimization of their design and functions has always been the focus of manufacturers. As one of the core components that determines the use effect of the fan, the performance of the fan rotation mechanism directly affects the fan's energy efficiency, safety and user comfort. However, in the prior art, the fan rotation mechanism still has some significant problems and needs to be further improved.

[0003] 1. Fixed shaking angle and limitation of blowing range: Most fan products on the market currently have shaking functions that are often set to a fixed angle range, such as 45 to 90 degrees on the left and right. Although this design can meet basic indoor air circulation needs, it has certain limitations in actual applications. Especially in scenarios where there are few people or local cooling is required, the fixed shaking angle often causes part of the blowing range to exceed the actual required area, resulting in energy waste and a decrease in user experience. For example, in a small room or office, the fan may continue to blow air into an empty corner, while the wind coverage of the main activity area is insufficient.

[0004] 2. The fan's center of gravity is too high and the problem of stability: In existing fan designs, in order to achieve the fan blade shaking function, the shaking drive mechanism is usually placed behind or above the fan blade assembly. This layout directly leads to the upward shift of the fan's overall center of gravity. The increase in the center of gravity not only affects the stability of the fan, but also increases the risk of accidental tipping during use, especially when it encounters external collisions or is used on uneven ground. In order to solve this safety hazard, many manufacturers choose to increase the size of the base or increase the weight of the base to enhance stability, but this undoubtedly brings new problems - the overall size of the fan increases, making it inconvenient to carry, and the production and transportation costs increase accordingly. At the same time, it does not conform to the trend of modern homes pursuing lightness and compactness.

[0005] In summary, the main problems with existing fan rotation mechanisms include the inflexible blowing range caused by the fixed shaking angle, the high center of gravity and reduced stability of the fan caused by the shaking mechanism layout, and the compensatory measures taken have caused the fan to be too heavy, inconvenient to move, and increased energy consumption. These problems not only affect the user experience, but also limit the further development and application scope of fan products. Therefore, exploring new rotation mechanism designs, realizing intelligent adjustment of the shaking angle, and optimizing the shaking mechanism layout to lower the center of gravity have become key directions for improving fan performance, ensuring safety of use, and improving energy efficiency.
