The inner end of the first flabellum and the second flabellum is stated in vertical direction in shifting to install, the first flabellum is set to pedestal side, and the
Width and wheel hub side equivalent width after the inside of one flabellum is combined with the inside of the second flabellum；Second flabellum includes inside
Portion and outside portion, the inside portion and the arc-shaped setting in outside portion, and the radian of inside portion is more than the crooked radian of outside portion；
In forming a lug boss on the outer surface of the second flabellum, bottom end and the outside portion bottom end of inside portion form overcurrent mouth for inside portion；Institute
The link position top of the inside portion and wheel hub of stating the second flabellum is additionally provided with strengthening portion.
Further, the crooked radian ratio of the first flabellum of the inside portion and same position of second flabellum is：(5~
6)：1.
Further, the strengthening portion is set to the top of the second flabellum, and extends towards latter flabellum component direction and set
It sets.
Further, inclined surface, the inclined surface are equipped between the inside portion bottom end and outside portion bottom end of second flabellum
It is equipped with rounded corner between inside portion and outside portion bottom end.
In conclusion the utility model is by being arranged flabellum component, the first flabellum and the second flabellum, first flabellum with
The inner end of second flabellum is staggered, and the inside portion complementary combinations of the first flabellum and the second flabellum are formed and wheel hub side height
Consistent flabellum is spent, to can not only increase air quantity, and air quantity can be made to be flowed between each flabellum, directly increase flabellum
Wind area is eaten, and the airflow pressure that the first flabellum generates can be formed multiple poly- pressure, effectively increased under the acting of the second flabellum
Wind pressure and air output.In addition, the setting of the overcurrent mouth, can enhance the wind flow on the inside of fan；Outside second flabellum inside portion
The radian on surface is more than the outside portion radian of the second flabellum, so as to enhance wind gathering intensity and the air quantity on the inside of the second flabellum, this
Utility model it is highly practical, have stronger dissemination.

Fig. 2 is the side schematic view of Fig. 1；
Fig. 3 is the diagrammatic cross-section of the flabellum of main part in Fig. 2.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1 to Figure 3, the utility model provides a kind of Wind Volume aerofoil fan, the Wind Volume aerofoil fan packet
It includes main part 10 and is set to the pedestal 20 at 10 back side of main part, the main part 10 includes wheel hub 11 and several flabellum components
12, several flabellum components 12 are distributed on the outer peripheral edge of wheel hub 11, and are uniformly distributed in diverging centered on wheel hub 11.
The flabellum component 12 includes the first flabellum 13 and the second flabellum 14, and first flabellum 13 includes connecting with wheel hub 11
The inner end 131 connect and the outboard end 132 opposite with inner end 131, the inner end 131 are in arc in the same direction with outboard end 132
Shape is arranged.The inner end 131 of first flabellum 13 extends to wheel hub 11 in vertical direction from 11 back side of wheel hub to positive direction
The outboard end 132 at the middle part of side, the first flabellum 13 extends to medial surface 112 from 11 lateral surface 111 of wheel hub.First flabellum 13
