Abstract
The utility model provides a fan impeller front plate and a fan applying the same. The impeller front plate comprises a body; and a folding portion is formed at the edge of the body. The provided front plate has the advantages of simple structure, thin material, and high strength. Deformation of the front plate with the running of the fan can be avoided, so that the running quality of the fan is improved.
Description
Technical field
The utility model relates to a kind of machinery, relates in particular to a kind of fan impeller front disc, and the blower fan of applying above-mentioned fan impeller front disc
Background technique
Blower fan is that to rely on input electric energy conversion be mechanical energy, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Existing blower fan generally comprises casing, and is arranged in main shaft, the impeller of casing, and intake grill etc.But the demand when intensity of the impeller shroud of existing blower fan often can not adapt to blower fan work, along with the use of blower fan, cover plate tends to deform, and then affects the normal operation of blower fan.
Model utility content
One of the purpose of this utility model is to provide a kind of fan impeller front disc.It has overcome in prior art, the problem that the intensity of the cover plate of blower fan is not high.
Another object of the present utility model is to provide a kind of blower fan of applying above-mentioned impeller shroud.
One of for achieving the above object, a kind of fan impeller front disc of the present utility model, described fan impeller front disc comprises body, is opened in the import on described body, the edge of described body is formed with bending part.
As further improvement of the utility model, described bending part is perpendicular to the wall of the body edges at place.
As further improvement of the utility model, the internal diameter linearity of the import of described body reduces.
As further improvement of the utility model, the inner diameter values of described bending part place edge is maximum.
For realizing above-mentioned another object, the utility model provides a kind of blower fan, and it comprises impeller shroud, and described impeller shroud comprises body, is opened in the import on described body, and the edge of described body is formed with bending part.
As further improvement of the utility model, described bending part is perpendicular to the wall of the body edges at place.
As further improvement of the utility model, the internal diameter linearity of the import of described body reduces.
As further improvement of the utility model, the inner diameter values of described bending part place edge is maximum.
Compared with prior art, the beneficial effects of the utility model are: fan impeller front disc of the present utility model is simple in structure, and intensity is higher, can, with the operation generation deformation of blower fan, not improve the quality of blower fan.
Accompanying drawing explanation
Fig. 1 is the floor map of an embodiment of fan impeller front disc of the present utility model;
Fig. 2 is the sectional view of A-A direction in Fig. 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings, the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills are according to these mode of execution institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
As shown in Figure 1 to Figure 2, blower fan of the present utility model comprises kind of an impeller shroud 10, and described impeller shroud 10 comprises body 11, is opened in the import 12 on described body 11, and the edge of described body 11 is formed with bending part 13.Above-mentioned bending part 13 forms the circle of a sealing.Preferably, bending part 13 extends from body 11 edge-perpendicular, and described bending part 13 is perpendicular to the wall at body 11 edges at place.
Further, the internal face of above-mentioned import 12 is arc surface.And the internal diameter linearity of import 12 reduces, thereby make above-mentioned impeller shroud 10 be tapering type, be also that its shape is roughly one tubaeform.The internal diameter of above-mentioned bending part 13 place edges is maximum.
Fan impeller front disc of the present utility model is simple in structure, and intensity is higher, can, with the operation generation deformation of blower fan, not improve the quality of blower fan.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
