Word can be implemented according to this.
It should be appreciated that used herein such as " have ", "comprising" and " comprising " term are not precluded from one or many
The presence or addition of individual other elements or its combination.
Embodiment one
With reference to shown in Fig. 1-2, a kind of dust catcher impeller at least includes:Front shroud 100, it is disc structure, the front-wheel
The middle part of lid 100 is provided with first through hole 110;Wheel cover 200, it is disc structure, and the edge of wheel cover 200 passes through a cylindrical shell
The kuppe 210 of structure is fixedly connected with the outward flange of the front shroud 100, and some second are offered on the kuppe 210
Through hole 211;And blade 300, it is fixedly installed between the front shroud 100 and the wheel cover 200, the blade 300
Including some primary blades 310 and some splitterr vanes 320, the primary blades 310 are in the front shroud 100 radially from described
One through hole edge is extended out to away from first preset distance of outward flange of front shroud 100, and the primary blades 310 are in the front-wheel
Lid 100 extends to the front side wall of wheel cover 200 on axial direction from the rear wall of front shroud 100, and the primary blades 310 are described
On the circumferencial direction of front shroud 100 self-retaining the first end of the front shroud 100 turn over first angle extend to be fixed on it is described
Second end of wheel cover 200, the primary blades 310 are uniformly arranged, and the splitterr vanes 320 are set parallel to the primary blades 310
Put.The first angle is 90 degree.The design structure of the primary blades 310 so that the air flow channel that primary blades 310 are divided into
Stroke becomes big, plays the air-flow for allowing impeller to produce more stable effect.
The splitterr vanes 320 are in the front shroud 100 radially from away from the preset distance of first through hole edge second
Place is extended out to away from the preset distance of 100 outward flange of front shroud the 3rd, and the splitterr vanes 320 are in the front shroud 100
The front side wall of wheel cover 200 is extended to from the rear wall of front shroud 100 on axially, the splitterr vanes 320 are before described
Self-retaining is extended to by first angle in the first end of the front shroud 100 and fixed in the rear on the circumferencial direction of wheel cap 100
Second end of wheel cap 200.The splitterr vanes 320 are uniformly arranged, on the splitterr vanes 320 and the quantity of primary blades 310
Correspond.3rd preset distance is less than first preset distance.The setting of the splitterr vanes 320, reduces master
The air flow channel space of the formation of blade 310, reduces the generation of axial flow.
Embodiment two
The non-homogeneous arrangement of splitterr vanes 320, splitterr vanes 320 described in adjacent two groups with it is corresponding closest
The spacing of the primary blades 310 is unequal.The splitterr vanes 320 and the spacing of the closest primary blades 310 be not small
In 1/10th of the spacing of primary blades 310 described in adjacent two groups.The splitterr vanes 320 are by between the primary blades 310
Each air flow channel is cut, if air flow channel size formed by splitting is identical, air when air flow channel is exported because
Similar motion state, easily produces resonance, produces larger noise, while reducing blower fan energy conversion efficiency.Therefore pass through
Control the position of splitterr vanes 320 so that difference avoids above mentioned problem to the air flow channel being split to form, meanwhile, shunt leaf
Piece 320 also cannot be too near apart from primary blades 310, and otherwise easy air easily produces howl when moving quickly through this narrow gap
Cry, and be arranged such splitterr vanes 320 and also do not have the effect for preferably suppressing axial flow.

The madial wall of wheel cover 200 is provided with some fuisw ribs from center to external radiation, and the fuisw rib is uniformly arranged
Cloth, the fuisw rib holds row level with both hands with the primary blades 310 positioned at the second of the wheel cover 200.The fuisw rib plays double
Effect, is on the one hand guided to air-flow direction, and on the other hand it further suppresses as the splitterr vanes 320
The axial flow that air is produced by inertia, so as to improve the energy conversion efficiency of blower fan.
From the above mentioned, pass through air therein in the air flow channel that blade of the present invention is constituted and possess stronger lead
Tropism, stability;The splitterr vanes reduce the space of air flow channel, reduce the generation of axial eddy;It is described by point
Blade is flowed by uneven distribution, the possibility that an equal amount of air-flow produces resonance is reduced, and reduces fan noise, lifting
The energy conversion efficiency of blower fan;The fuisw rib guides airflow direction, reduces the generation of axial eddy;The present invention is led by described
The further guiding airflow direction of stream cover, increases the stability of whole blower fan.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With.It can be applied to various suitable the field of the invention completely., can be easily for those skilled in the art
