Claim 4:
5. The power device according to claim 1, wherein in the shell body of the impeller, the inner channels communicate with the outer channels through the plurality of second air ports; the outer channels communicate with the outside through the plurality of first air ports; the flow speeds of the fluid layers in the inner channels are lower than the flow speeds of fluids around the impeller, and the flow speeds of the high-speed fluid layers are higher than the flow speeds of the fluids around the impeller, so that the different flow speeds between the fluid layers in the inner channels and the fluid layers in the outer channels generate the outward pressure differences, whose pressure direction is opposite to the direction of the outside pressure of the impeller for them to be mutually counteracted.
