Specific embodiment
Multifunctional fan blade wheel hub of the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to 4, multifunctional fan blade wheel hub of the present invention, including：Hub body 1 and it is arranged in hub body 1
Axial blade 2 on outer circumference surface.The centrifuge blade 3 of multi-disc uniform intervals setting is provided with the inwall of the circumference of hub body 1,
The side long of centrifuge blade 3 axial direction side itself is fixed with the inwall of the circumference of hub body 1, what axial opposite side was provided with by one end
Draw-in groove 4 connected and fixed with outer annular-stiffer 5 or be directly integrally formed with outer annular-stiffer 5 and hub body 1.Centrifuge blade 3
Armature winding (heat generating member) is radiated, while also to the radiating of the electric component such as stator magnetic shoe and brush, inductance, and its shape
Using it is curved leaf or it is curved plunder combination shape, can increase the air quantity of fan and reduce noise.
Interior reinforcing ring 6 and outer annular-stiffer 5 are all disposed within the inner side of the end face of hub body 1, and interior reinforcing ring 6 is coaxially disposed
In outer annular-stiffer 5.It is provided with multiple equally distributed logical on the end face of hub body 1 between interior reinforcing ring 6 and outer annular-stiffer 5
Air holes 7, negative pressure can be produced when motor rotates, and can not only be radiated, and also for centrifuge blade 3 provides air intake, strengthen the effect of radiating.
Meanwhile, reinforcement 8 is set between interior reinforcing ring 6 and outer annular-stiffer 5 and reinforcement 8 sets with the interval of air vent 7
Put, play a part of reinforcing.In addition, centrifuge blade 3 also, while having the effect of reinforcement, can make wind as the supplement of reinforcement 8
