Refer to Fig. 1 and Fig. 2, the wind wheel 100 of the utility model embodiment include first wheel 10, the second wheel hub 20,
Multiple first blades 30 and multiple second blades 40.
First wheel 10 is coaxially disposed with the second wheel hub 20.Multiple first blades 30 are fixedly connected with first wheel 10 and second
Wheel hub 20.Multiple first blades 30 are intervally arranged.Multiple second blades 40 are fixed on the lateral surface 22 of the second wheel hub 20.Multiple
Two blades 40 are intervally arranged.The gross area Σ S1 of multiple first blades 30 are more than the gross area Σ S2 of multiple second blades 40.
In above-mentioned wind wheel 100, because the gross area of the first blade 30 of wind wheel 100 is more than the gross area of the second blade 40,
First blade 30 produces large effect to overall air-flow caused by wind wheel 100, the first blade 30 is produced with the second blade 40
Air-flow can spread after converging, and so as to increase the blowing area of wind wheel 100, meet the demand of user.
In addition, air-flow caused by the first blade 30 and the second blade 40 converges interaction, the centrifugal force of wind wheel 100 can be reduced
Caused eddy current effect, the wind after diffusion is more nearly natural wind, improve Consumer's Experience.
Inventor will detect wind wheel 100 and existing wind wheel according to the utility model embodiment under identical conditions
Parameter be compared, wherein being compared to obtain table 1 to air quantity and noise when rotating speed is close:
Table 1
Noise is compared when air quantity is identical to obtain table 2:
Table 2
As can be seen from Table 1, when rotating speed is close, the air quantity of the wind wheel 100 of present embodiment is significantly greater than existing wind
The air quantity of wheel, but noise difference is smaller, the influence to user is little.
As can be seen from Table 2, when air quantity is identical, the noise of the wind wheel 100 of present embodiment is significantly lower than existing wind
The noise of wheel, rotating speed and power are also significantly lower than existing wind wheel, therefore can save electricity.
It should be noted that in present embodiment, it can be understood as, first wheel 10 is inner wheel hub, and the second wheel hub 20 is
Outer wheel hub.First blade 30 is intra vane, and the second blade 40 is outer leafs.
Center of rotation of the first wheel 10 compared with the second wheel hub 20 close to wind wheel 100, the first blade 30 lean on compared with the second blade 40
The center of rotation of nearly wind wheel 100.
Specifically, the inner end edge 32 of multiple first blades 30 is connected on the lateral wall 12 of first wheel 10.Multiple
The outer end edges 34 of one blade 30 are connected on the medial surface 24 of the second wheel hub 20.
The wheel hub 20 of first wheel 10 and second is directly connected by the first blade 30, reduces the complicated of wind wheel 100
Degree, wind wheel 100 is set to be more prone to manufacture.
In present embodiment, multiple first blades 30 are radial centered on first wheel 10 to be intervally arranged.
In this way, being advantageous to the first blade 30 connection wheel hub 20 of first wheel 10 and second, the intensity of wind wheel 100 can be improved.
In present embodiment, multiple second blades 40 are radial centered on first wheel 10 to be intervally arranged.
The incoming air area of wind wheel 100 can so be increased, be advantageous to increase the air output of wind wheel 100.

Angle between two adjacent the first blades 30 is equal, can so facilitate the manufacture of wind wheel 100, additionally it is possible to the first blade 30 is existed
The uniform air-flow of speed is produced on circumferencial direction, ensures that the first blade 30 and the second blade 40 are produced after air-flow converges and can expanded
Dissipate, so as to increase the blowing area of wind wheel 100.
In present embodiment, circumferencial direction of second blade 40 along the second wheel hub 20 is uniformly distributed.
In this way, being advantageous to the manufacture of wind wheel 100, and make the caused current density of wind wheel 100 uniform, be advantageous to gas
Flowing.
In addition, the circumferencial direction of the first blade 30 and the second blade 40 along wind wheel 100 is uniformly distributed, additionally it is possible to ensures wind
Under static state, the mass cg of wind wheel 100 is located in the center of rotation of wind wheel 100 wheel 100.Wind wheel can so be reduced
Vibration during 100 rotation, caused noise is rotated so as to reduce wind wheel 100.
Specifically, first wheel 10 offers centre bore 14, and wind wheel 100 can be connected by the rotary shaft of centre bore 14 and motor
Connect, motor driving wind wheel 100 rotates.
In present embodiment, the angle of attack of the first blade 30 is more than the angle of attack of the second blade 40.
In this way, wind wheel 100 has preferable aeroperformance, the efficiency of wind wheel 100 is improved, and make the wind of present embodiment
Wheel 100 is compared with traditional wind wheel, and under identical rotating speed, air quantity caused by wind wheel 100 is bigger.
In present embodiment, the first blade 30 is airfoil fan.
Because airfoil fan has preferable aeroperformance, each aeroperformance of first blade 30 can be so improved, and
And first blade 30 it is larger to the overall airflow influence of wind wheel 100, can so improve the aeroperformance of wind wheel 100, reduce wind
The power attenuation of wheel 100, has saved the energy (such as electric energy).
Specifically, the structure all same of multiple first blades 30, that is to say, that the overall structure of each first blade 30
It is identical, it can so facilitate the manufacture of wind wheel 100.
Further, the first blade 30 is the airfoil fan of distortion.Due to the shape of the blade of distortion and the flowing of air-flow
Rule is consistent, and can so reduce the loss of gas flowing, improves the efficiency of wind wheel 100.
It is preferred that the second blade 40 is airfoil fan.It so can further improve the aeroperformance of wind wheel 100.
In addition, airfoil fan is for example designed by bionical object of the assistant of flying bird.Specifically, in one example,
First blade 30 may be designed as secondary feather shape, and the second blade 40 may be designed as primaries shape, just can so design profile
Two layers different of blades, its advantage are:1. the profile of blade uses Bionic Design, make blade that there is good aeroperformance, and
Overall appearance after assembling;2. twi-tier blade designs, wind sweeping area can be added, improves air quantity;3. the middle outer wheel hub of twi-tier blade
Design, the intensity of blade is improved, extend working life.
