Abstract
The utility model relates to a vane wheel which comprises a cone-shaped body, vanes and a fixing seat. The vane wheel is formed by injection molding at one time. The fixing seat is in the cone-shaped body. Connecting holes are formed in the fixing seat, wherein the connecting holes are matched with flanges of the output shaft of an aerobic machine. A plurality of vanes are arranged on the outer side of the aerobic machine. Vanes are combined with the cone-shaped body in an inclining mode. Water patting plates are arranged on the upper end of the outer side of the cone-shaped body, wherein the water patting plates are basically vertical to the upper end face of the cone-shaped body. A working face A of each water patting plate and a working face C of each vane are transited smoothly. Water flow driven by the vanes splashes upward through each working face C of each water patting plate and water is heightened and the water is scattered, then the connecting face between the water and the air is increased and aerobic effect is improved. Weight of an alloy aluminum die-casting reduction gearbox is substantially reduced. The other end of a support rod can use a flat floating ball with small volume to enable the aerobic machine to float on the water surface. The flat surface is relatively parallel to the water flow direction when the aerobic machine works. When the aerobic machine works, resistance from the floating body to the water flow is reduced and aerobic efficiency is improved.
