Abstract: An impeller includes a hub, an outer ring, a plurality of first blades and a plurality of second blades. The plurality of first blades are arranged around the hub at intervals. Each of the plurality of first blades passes through the outer ring, extends inward from the outer ring, and is connected to the hub. The plurality of second blades are arranged around the hub at intervals. Each of the plurality of second blades passes through the outer ring. At least one of the plurality of second blades is disposed between the plurality of first blades. A length of each of the plurality of second blades is between 10% and 45% of a length of each of the plurality of first blades.
