[0002] Portable bladeless fans are a modern personal cooling device that is favored by many users for their safety, portability and ease of cleaning. The bladeless design means that the fan has no traditional exposed blades, which not only makes it look more modern, but also eliminates the risk of pinching fingers. It is especially suitable for environments with children at home. These fans are usually lightweight and can be charged via USB, making them ideal for outdoor activities, travel or office use.

[0003] Traditional portable bladeless fans have a one-piece manufactured air duct, which is difficult to replace. This makes it difficult to replace the air duct when it is damaged, requiring the replacement of the entire fan. This makes it difficult for users to replace the entire portable bladeless fan at home, and replacing the entire portable bladeless fan also increases the cost. Finally, after replacing the portable bladeless fan, users may experience discomfort in the short term.

[0004] Therefore, to address the issue that the air duct of traditional portable bladeless fans is manufactured as a single unit, making it difficult to replace and replace the air duct when it is damaged, a design can be made that uses threads to fix the air duct, making the portable bladeless fan easy to disassemble. This allows for easy replacement of only the air duct when it is damaged, without having to replace the entire fan. This enables users to replace the fan at home, reduces the cost of replacing the entire fan, and avoids the discomfort of short-term use after replacing the fan. Utility Model Content
