Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a fan that can be held in place by an umbrella. Background Technology

[0002] Personal fans are electrical appliances used to cool down in hot weather, and they are popular among consumers because of their practical functions.

[0003] In summer, due to the strong sunlight, we often use umbrellas for sun protection when we go out. However, when using an umbrella, we need to free one hand to hold it, making it difficult to use another hand to hold a fan for cooling. This severely limits the use of a personal fan while holding an umbrella. To address this issue, Chinese utility model patent CN212615467U discloses a technical solution for "a fan applied to an umbrella." This solution allows a personal fan to be clipped onto the umbrella handle, thus saving hand space and resolving the aforementioned limitations to some extent.

[0004] However, this technical solution is prone to problems during implementation, such as the cover plate cracking or the clamping mechanism loosening and shifting. This is because the outer diameter of umbrella rods of different models is often different. If used on umbrella rods with a larger outer diameter, the cover plate may crack due to overfilling. If used on umbrella rods with a smaller outer diameter, the clamping mechanism may loosen and shift or fail to clamp properly due to the inability to clamp tightly. This seriously reduces the effectiveness and applicability of the technical solution. Utility Model Content
