Air holes.
Due to traditional impeller, its blade is only fixed with rear trochal disc, and another side does not support, in the process of high speed rotating
In the most unstable, be easily deformed or damage so that fan airflow is unstable, weak effect of blowing, use said structure posterior lobe
Sheet both sides are connected on ring support and on rear trochal disc, enhance the overall structure of blade and impeller assembly so that it is at a high speed
During rotation more stable；After gas enters blower fan, directly enter impeller assembly through air vent and then pass to the air outlet on blower fan,
Not spiraling in remaining place of blower fan, prevent the formation of eddy current, gas is disposably by blower fan, without stopping gas so that air-flow is put down
Surely, blower fan work efficiency is high.
Each described blade is all connected with ring support, and described blades leading edges is additionally provided with locating dowel, and described impeller end lid is opened
It is provided with the installing hole corresponding with described locating dowel.It is fixing that this structure is easy between impeller end cap and blade installation.
Being further opened with the groove that a plurality of and described blades leading edges adapts on described impeller end lid, described installing hole offers this groove
Bottom, described blades leading edges and locating dowel coordinate with groove and installing hole respectively.Blade is connected with impeller end cap in stretching into groove
Fixing more firm.
Described impeller end cap is loop configuration, and described installing hole is near the edge of impeller end cap.
Described blade is arc, and described groove is arcuate groove, and described locating dowel is positioned at blade one end near rear trochal disc center.
Described blade rear edge embeds in rear trochal disc, and described blades leading edges embeds in ring support, and described impeller end cap is positioned at ring
In shape support inner ring, this impeller end cap periphery is fitted with ring support inner headed face, the front end face of impeller end cap and ring support side
Face is concordant.This structure makes impeller end cap be fully immersed into ring support inner ring, it is to avoid produces with other structures of blower fan and interferes.
Described ring support is one-body molded with blade and rear trochal disc, and one-body molded intensity is higher.
The adapter sleeve for connecting electric machine main shaft it is provided with on described rear trochal disc.
As it has been described above, the invention has the beneficial effects as follows: blade both sides are connected on ring support and on rear trochal disc, enhance
Blade and the overall structure of impeller assembly so that it is more stable when high speed rotating；The installation of impeller end cap is easy to connect, and gas enters
After entering blower fan, directly enter impeller assembly through air vent and then pass to the air outlet on blower fan, do not spiral in remaining place of blower fan,
Preventing the formation of eddy current, gas is disposably by blower fan, and without stopping gas so that air-flow is steady, blower fan work efficiency is high.

Detailed description of the invention
By particular specific embodiment, embodiments of the present invention being described below, those skilled in the art can be taken off by this specification
The content of dew understands other advantages and effect of the present invention easily.
As shown in Figure 1 to Figure 3, the present invention provides a kind of draught fan impeller assembly, including the ring support 22 set gradually, blade
23 and rear trochal disc 21, blade 23 back edge is fixing with rear trochal disc 21 to be connected, and blade 23 leading edge is connected with ring support 22,
Being also equipped with impeller end cap 3 on blade 23 leading edge, this impeller end cap 3 covers blade 23, impeller end cap 3 outer rim and annular
Frame 22 inner ring coordinates, and impeller end cap 3 offers air vent 31, and each blade 23 is all connected with ring support 22, blade
23 leading edges are additionally provided with locating dowel 24, and impeller end cap 3 offers the installing hole 32 corresponding with locating dowel 24, and this structure is just
