Furthermore, in technique scheme, the upper end of described rib and the end face of boss maintain an equal level.
Furthermore, in technique scheme, described rib is curved, and its periphery along boss end face extends out to the periphery of wheel hub, and the periphery of its end and wheel hub maintains an equal level.
Furthermore, in technique scheme, between adjacent two ribs, form the air guide channel of an inclination.
Furthermore, in technique scheme, the part that described blade is connected with wheel hub periphery is the image shape of S font.
Furthermore, in technique scheme, the arc rotary direction of described blade and the arc rotary opposite direction of rib.
Furthermore, in technique scheme, the peak of the upper end-face edge of described blade is lower than the end face of boss.
Furthermore, in technique scheme, the shape a that has angle between the lower edge of described blade and wheel hub lower edge, the value of this angle a is 0-8 °.
Furthermore, in technique scheme, the shape b that has angle between the upper end-face edge of described blade and the periphery of wheel hub, the value of this angle b is 28 °-33 °.
Adopt after technique scheme, the utility model has following beneficial effect compared with prior art: the utility model is in the time carrying out high speed rotating, because the peripheral part being connected of blade and wheel hub is the image shape of S font, and the upper end-face edge of blade is circular arc, it is beneficial to wind cutting, moreover, on wheel hub, the rib of moulding can play good wind-guiding effect, the air guide channel of the inclination forming between rib makes flabellum wind cutting in rotation process more smooth and easy, the number of turns that the utility model is rotated the in the situation that of equal voltage is higher, in the situation that rotating the equal number of turns, noise is less, and the in the situation that of equal voltage and the equal number of turns of rotation, consumed power is less.In addition, the recess that blade lower edge forms makes whole flabellum can greatly increase air output in high speed rotating process, to improve the heat radiation function of whole flabellum.In sum, the utlity model has the advantage that air output is large, noise is low, power is low, so that there is the higher market competitiveness.
