Intensity, to improve the service life of product.
In the above embodiment, it is preferable that as depicted in figs. 1 and 2, multiple first blades 124 and/or multiple second blades
144 cross section is curved, the cross section of multiple first blades 124 and/or multiple second blades 144 to centering angle be more than
0 ° is less than or equal to 90 °.
In this embodiment, by the way that the first blade 124 and/or the second blade 144 are arranged into camber, specifically, such as
In crescent such that it is able to change the flow direction of wind using the blade of arc, so that wind is from the first blade 124 and/or second
The tangential direction in the outside of blade 144 flows out, and to realize the radial direction air-out of centrifugal wind wheel 1, and passes through multiple first blades 124
And/or the cross section of multiple second blades 144 to centering angle be disposed greater than 0 ° less than or equal in the range of 90 °, can
Make the first blade 124 and/or the second blade 144 that there is enough width and radian, and and be unlikely to curved transitions and cause wind
Can not flow out from the radial direction of wind wheel, wherein it is preferred to, multiple first blades 124 and/or multiple second blades 144
Cross section to centering angle more than or equal to 20 ° be less than or equal to 60 °, specifically, such as more than or equal to 30 ° be less than or equal to 60 °.
In the above embodiment, it is preferable that as depicted in figs. 1 and 2, multiple first blades 124 on the first chassis 122 from
Interior to arrange to outer incline, and incline direction of multiple first blades 124 on the first chassis 122 from the inside to the outside is consistent；Wherein, it is many
Individual second blade 144 is obliquely installed from the inside to the outside on the second chassis 142, and multiple second blades 144 are on the second chassis 142
Incline direction from the inside to the outside is consistent, and multiple first blades 124 are consistent with the incline direction of multiple second blades 144.
In this embodiment, incline direction of multiple first blades 124 on the first chassis 122 is consistent so that the first wind
Air-out direction between multiple first blades 124 of wheel 12 is consistent, it is thus possible to make the normal air-out of the first wind wheel 12, to guarantee the
The air output of one wind wheel 12, and incline direction of multiple second blades 144 on the second chassis 142 is consistent so that the second wind wheel
Air-out direction between 14 multiple second blades 144 is consistent, it is thus possible to the normal air-out of the second wind wheel 14 is made, to guarantee second
The air output of wind wheel 14, and make multiple first blades 124 consistent with the incline direction of multiple second blades 144 so that the first wind
Wheel 12 is consistent with the air-out direction of the second wind wheel 14, thus the wind energy that the first wind wheel 12 is discharged enough moves smoothly through the second wind wheel 14
Discharge, and be unlikely to be stopped by the second wind wheel 14, so enable the second wind wheel 14 to the wind of the outflow of the first wind wheel 12 again
Secondary pressurization, so that more air can be flowed in centrifugal wind wheel 1, to increase the air quantity of centrifugal wind wheel 1.
Wherein, specifically, the first blade 124 i.e. can be with as shown in figure 1, from the inside to the outside to up time on the first chassis 122
Pin direction inclines, and now, the second blade 144 is inclined clockwise from the inside to the outside on the second chassis 142, it is also possible to as schemed
Shown in 2, it is obliquely installed counterclockwise from the inside to the outside on the first chassis 122, now, the second blade 144 is on the second chassis
Incline counterclockwise from the inside to the outside on 142.
In the above embodiment, it is preferable that multiple first blades 124 with multiple second blades 144 in the footpath of centrifugal wind wheel 1
Mutually stagger upwards setting.
In this embodiment, because the first blade 124 and the second blade 144 are with certain radian and the leaf that is obliquely installed
Piece, therefore, wind is entered into after the first wind wheel 12 can flow out from the tangential direction in the outside of the first blade 124, and pass through will be multiple
First blade 124, in the setting of radially mutually staggering of centrifugal wind wheel 1, can make the second blade 144 with multiple second blades 144
Be placed exactly in the tangential direction in the outside of the first blade 124, thus wind from the first blade 124 outflow after can flow directly into
Second blade 144, it is thus possible to resistance of second wind wheel 14 to wind is reduced, to guarantee air quantity.
