Fan blade is made of the second circular base plate, the second blade and the second outer ring, and the second blade is multi-disc, the second blade bottom end of multi-disc and the
The outer ledge of two circular base plate top surfaces is linked together, and the second outer ring and the lateral wall of the second vane tip are linked together, blade
Top is linked together with the second circular base plate inside bottom surface edge；Second circular base plate diameter is more than circular base plate.
Preferably, the second circular base plate inside bottom surface edge is equipped with the sealing wire in circular arrangement, vane tip is logical
Sealing wire is crossed to be welded and fixed with the second circular base plate bottom surface；It is against on the second circular base plate bottom surface at the top of outer ring, at the position of outer ring
In the outside of sealing wire.Connection precision and firmness of the connection are high, improve the service life of centrifugation blade.
Preferably, blade is 37~65；Second blade is 37~65.
Preferably, wheel hub is equipped with multiple province's material mouths, production cost is reduced.
A kind of centrifugation blade of above-mentioned technical proposal is used, vane tip is equipped with the second fan blade, the second blade of multi-disc bottom
The outer ledge with the second circular base plate top surface is held to be linked together, the second outer ring and the lateral wall of the second vane tip are linked as one
Body, vane tip are linked together with the second circular base plate inside bottom surface edge；Second circular base plate diameter is more than circular base plate, uses
Twi-tier blade structure, can optimize air duct, make full use of axial space, increase fan blade air inlet/outlet work area, tradition from
The fan blade of a circle larger diameter is increased on heart fan blade, air quantity can be obviously improved, generally 50% or more, due to increased fan blade
Being not provided with wheel hub, therefore the increase of fan blade weight is limited, and fan efficiency is promoted apparent.In conclusion the advantages of centrifugation blade is knot
Structure is novel, increases fan blade air inlet/outlet work area, air quantity and fan efficiency are obviously improved.
Description of the drawings
Fig. 1：The structural schematic diagram one of the utility model embodiment.
Fig. 2：The structural schematic diagram two of the utility model embodiment.
Specific implementation mode
1 and Fig. 2 makes a detailed explanation specific embodiment of the present utility model below in conjunction with the accompanying drawings.
A kind of centrifugation blade as depicted in figs. 1 and 2, including circular base plate 1, wheel hub 2, more blades 3, outer ring 4 and
Two fan blades 5, wheel hub 2 are equipped with multiple province's material mouths 21, and circular base plate 1, wheel hub 2, more blades 3, outer ring 4 constitute the first fan blade,
2 outside of wheel hub is linked together with 1 inside of circular base plate, and 3 bottom end of blade and the lateral border of 1 top surface of circular base plate are linked together, outside
Circle 4 and the lateral wall at 3 top of blade are linked together, and blade 3 is 37~65.
Second fan blade 5 is fixed on 3 top of blade, and the second fan blade 5 is by the second circular base plate 6, the second blade 7 and the second outer ring
8 are constituted, and the second blade 7 is 37~65, and 7 bottom end of the second blade and the outer ledge of 6 top surface of the second circular base plate are linked together,
The lateral wall of second outer ring 8 and 7 top of the second blade is linked together, and 3 top of blade connects with 6 inside bottom surface edge of the second circular base plate
It is integrated, specifically：Second circular base plate, 6 inside bottom surface edge is equipped with the sealing wire 61 in circular arrangement, and 3 top of blade is logical
Sealing wire 61 is crossed to fix with the 6 bottom surface ultrasonic bonding of the second circular base plate.4 top of outer ring is against on 6 bottom surface of the second circular base plate,
4 position of outer ring is in the outside of sealing wire 61, can improve connection precision and firmness of the connection using the connection of sealing wire 61, in turn
Promote the service life of centrifugation blade.
Second circular base plate, 6 diameter is more than circular base plate 1, i.e. 5 diameter of the second fan blade is more than the first fan blade.This patent from
Heart fan blade uses twi-tier blade structure, can optimize air duct, makes full use of axial space, increases fan blade air inlet/outlet working face
Product increases the second fan blade of a circle larger diameter on traditional first fan blade, and air quantity can be obviously improved, generally 50% with
On, since increased fan blade is not provided with wheel hub, therefore the increase of fan blade weight is limited, and generally below 15%, fan efficiency is promoted bright
It is aobvious, generally 30% or more.
The inclination angle A angles of above-mentioned adjacent blades are different, and the inclination angles of arbitrary blade are between 3 °~11 °.Blade
Inclination angle A is that projection and blade tip of the blade bottom end in circular base plate being projected in circular base plate are right in circular base plate
The central angle answered.The inclination angles of above-mentioned second adjacent blade are different, and the inclination angles of arbitrary second blade are at 3 °~11 °
Between.Second blade pitch angle is projection and second blade tip of second blade bottom end in the second circular base plate in the second circle
It is projected in corresponding central angle in the second circular base plate on shape chassis.The inclination angles of adjacent blades are different, and adjacent second
The inclination angles of blade are different, can reduce the secondary gas before and after blade and the second blade after centrifugation blade air-flow turns to
Pressure difference makes air-flow smooth fluctuation, keeps air-conditioning sound of the wind more naturally comfortable.
