Abstract
A fan blade structure applied to a centrifugal fan is provided. The fan blade structure includes a wheel hub and an annular vane. The wheel hub includes a plurality of connecting brackets, and the annular vane includes multiple crests and troughs which interlace to form a continuous curved surface. The continuous curved surface has an outer ring surface and an inner ring surface. The connecting brackets are connected to the inner ring surface and drive the annular vane to rotate.
