Abstract
The utility model relates to a centrifugal air wheel contains multi -disc blade, reinforcing ring and hub, and multi -disc blades annular blading is connected with circular shape hub and annular reinforcing ring respectively, wherein the outward flange that radially stretches out the hub of one side edge hub of every blade. The wind wheel of this kind of structure is in the easier drawing of patterns of the in -process of moulding plastics to wind wheel air supply volume has in the course of the work been improved.
Description
Technical field
The utility model relates to aeration technology field, specifically refers to a kind of wind wheel being applied to centrifugal fan.
Background technique
Centrifugal wind wheel generally comprises wheel hub, and the blade be connected with wheel hub and the stiffening ring being connected to blade other end form.During centrifugal blower work, wind wheel High Rotation Speed, air enters wind wheel center along the axis of centrifugal wind wheel, and flows to surrounding at the effect Xia You center of blade, forms radial air flow.
In the prior art, the external profile diameter of the annular blade group of centrifugal wind wheel is less than hub diameter, and wind wheel blade when injection moulding of this structural type is all arranged in dynamic model, and the large sticking to mould power on dynamic model can cause the ejection device process of wind wheel more difficult.
Model utility content
The purpose of this utility model is the weakness overcoming centrifugal wind wheel injection moulding demoulding difficulty in prior art, provides a kind of centrifugal wind wheel being convenient to the demoulding.
The technological scheme realizing the utility model object is: the structural type of change centrifugal wind wheel, new centrifugal wind wheel comprises more blades, stiffening ring and wheel hub, more blades forms annular vane group and is connected with the stiffening ring of the wheel hub of circle and annular respectively, wherein often the side of sheet blade along the outward edge extending radially out wheel hub of wheel hub.
Further optimization, the inner diameter of centrifugal wind wheel annular blade group is less than the diameter of wheel hub.
Further optimization, the outward edge of wheel hub is stretched out along the axis of wheel hub in one end of the every sheet blade of centrifugal wind wheel.
Further optimization, centrifugal wind wheel every sheet blade meets along the length H of outer peripheral distance H1 and every sheet blade that the axis of wheel hub stretches out wheel hub: 0.05H < H1 < 0.5H.
The utility model has positive effect: the side of (1) centrifugal wind wheel every sheet blade is along the outer peripheral structure extending radially out wheel hub of wheel hub, make wind wheel at injection moulding process Leaf between dynamic, cover half, thus the sticking to mould power reduced on dynamic model, be convenient to the demoulding.(2) side of centrifugal wind wheel every sheet blade adds the air supply areas of blade integral along the outer peripheral structure extending radially out wheel hub of wheel hub, improves air output.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is that the axle of centrifugal wind wheel surveys view.
Fig. 2 is the axle front view of centrifugal wind wheel.
Fig. 3 is the right elevation of centrifugal wind wheel.
Label in accompanying drawing is:
Stiffening ring 1, blade 2, wheel hub 3, air-supply face 4.
Embodiment
(embodiment 1)
As shown in Figure 1 to Figure 3, the utility model provides a kind of centrifugal wind wheel, it comprises stiffening ring 1, more blades 2 and wheel hub 3, more blades 2 forms annular vane group and is connected with the wheel hub 3 of circle and the stiffening ring 1 of annular respectively, and the side of the every sheet blade of centrifugal wind wheel is along the outward edge extending radially out wheel hub of wheel hub.Compared with centrifugal wind wheel of the prior art, the centrifugal wind wheel of new structure has had more air-supply face 4.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
