Abstract
The utility model provides an inlet assembly of a draught fan and the draught fan with the inlet assembly. The inlet assembly of the draught fan comprises a body and vent holes, wherein the vent holes are formed in the body, and protrusion portions are formed at the parts close to the edges of the body. The inlet assembly of the draught fan is simple in structure and high in strength and will not deform in the operation process of the draught fan. Meanwhile, the inlet assembly of the draught fan is high in flatness, and therefore the draught fan is convenient to assemble.
Description
Technical field
The utility model relates to a kind of machinery, relates in particular to a kind of blower fan import assembly, and the blower fan of applying above-mentioned blower fan import assembly
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 the import assembly at air intake place etc.But the demand when intensity of the import assembly of existing blower fan and flatness often can not adapt to blower fan work, along with the use of blower fan, import assembly 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 blower fan import assembly.It has overcome in prior art, the intensity of the import assembly of blower fan and the not high problem of flatness.
Another object of the present utility model is to provide a kind of blower fan of applying above-mentioned import assembly.
One of for achieving the above object, a kind of blower fan import assembly of the present utility model, described blower fan import assembly comprises body, is opened in the vent hole on described body, the edge of closing on of described body is formed with lug boss.
As further improvement of the utility model, the one projection and going out on described body of described lug boss.
As further improvement of the utility model, described lug boss forms the annulus of a sealing.
As further improvement of the utility model, described body is circular, and described lug boss overlaps with the center of circle of described body.
For realizing above-mentioned another object, the utility model provides a kind of blower fan, and it comprises import assembly, and described import assembly comprises body, is opened in the vent hole on described body, and the edge of closing on of described body is formed with lug boss.
As further improvement of the utility model, the one projection and going out on described body of described lug boss.
As further improvement of the utility model, described lug boss forms the annulus of a sealing.
As further improvement of the utility model, described body is circular, and described lug boss overlaps with the center of circle of described body.
Compared with prior art, the beneficial effects of the utility model are: blower fan import modular construction of the present utility model is simple, and intensity is higher, can be with the operation generation deformation of blower fan, and meanwhile, blower fan import assembly flatness is higher, is convenient to assembling and the assembling of blower fan.
Accompanying drawing explanation
Fig. 1 is the floor map of an embodiment of blower fan import assembly of the present utility model;
Fig. 2 is the broken section enlarged 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 import assembly 10, and described import assembly 10 comprises body 11, is opened in the vent hole 12 on described body 11, and the edge of closing on of described body 11 is formed with lug boss 13.The one projection and going out on body 11 of above-mentioned lug boss 13, it forms the circle of a sealing.Preferably, described body 11 is circular, and described lug boss 13 overlaps with the center of circle of described body 11.
Further, the internal face of above-mentioned vent hole 12 is arc surface.And the internal diameter linearity of vent hole 12 reduces, thereby make above-mentioned import assembly 10 be tapering type, be also that its shape is roughly one tubaeform.In present embodiment, above-mentioned lug boss 13 forms by impact style, and its cross section is semicircle.
In addition, above-mentioned body 11 closes on lug boss 13 places and is also evenly equipped with some mounting holes 14, and the arrangement track of some mounting holes 14 is circular.
Blower fan import modular construction of the present utility model is simple, and intensity is higher, can be with the operation generation deformation of blower fan, and meanwhile, blower fan import assembly flatness is higher, is convenient to assembling and the assembling 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.
