Abstract
A detachable fan is provided. The fan includes a motor provided with a main shaft extending axially, fan blade assemblies including blade portions circumferentially assembled to enclose a complete circular fan and sleeve portions, and a retaining cap fixed to a top end of the main shaft and in contact with top end surfaces of the sleeve portions to restrict upward movement of the fan blade assemblies along the main shaft. A blocking member is provided on a side wall of the main shaft. The sleeve portions are sequentially stacked along an axial direction of the main shaft, and a lowermost sleeve portion abuts against the blocking member. The present application reduces packaging volume and transportation costs by dividing a conventional integrated blade set into multiple individually detachable fan blade assemblies, which can be separately packaged and stacked, and is particularly well-suited for the logistics and warehousing of large-sized fans.
