Description
Technical field
The utility model belongs to technical field of industrial equipment, relates to a kind of blower fan.
Background technique
Blower fan is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.At present, more common blower fan (being commonly called as iron-clad blower fan) generally comprises the shell of cartridge type, motor, flabellum and base, during use, puts in place by this blower fan, motor access power supply.Operationally, flabellum High Rotation Speed, and produce air-flow, this air-flow can cause larger impact to flabellum to blower fan, therefore, if fixing bad of flabellum, will badly influence the normal use of blower fan.And one end of flabellum is just fixed by the fan of market at present, the other end is unsettled, so when flabellum High Rotation Speed, will have the trend of rocking owing to being subject to the impact of air-flow, in the course of time, just can cause loosening of flabellum, affect blower fan and normally blow.Therefore, be necessary improving.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one according to circumstances, has the function preventing flabellum from rocking.
For achieving the above object, the utility model provides following technological scheme:
A kind of blower fan, comprise cylindrical shell, base, motor and some flabellums, the inwall of described cylindrical shell is provided with an annular groove, every sheet flabellum is all installed with a mounting blocks near one end of annular groove, described mounting blocks is provided with a containing groove towards the side of described annular groove, be provided with a ball between described annular groove and containing groove, the inwall of described ball and this annular groove and containing groove is all fitted.
Further, also comprise a connecting ring, described connecting ring penetrates every block mounting blocks successively.
Further, a through hole be communicated with cylindrical shell outer wall is provided with in described annular groove.
Further, the connectivity part of described through hole and annular groove is provided with a sponge.
Further, the outer wall of described cylindrical shell is provided with an oil bucket, and described oil bucket is communicated with this through hole.
Compared with prior art, the utility model has the advantages that:
By above-mentioned setting, ball is merely able to circle in annular groove, identical with the rotary motion trace of flabellum, therefore, can't have influence on the normal rotation of flabellum; In addition, and fit completely due to the mounting blocks on flabellum and ball, therefore, the working principle of reference bearing, is equivalent to flabellum two ends and is obtained for fixing, so, just completely eliminate the defect of the unsettled setting in one end of flabellum in prior art, the normal rotation of flabellum can also be ensured simultaneously.

Accompanying drawing marks: 1, cylindrical shell, and 11, through hole, 2, base, 3, motor, 4, flabellum, 5, annular groove, 6, mounting blocks, 61, containing groove, 7, connecting ring, 8, ball, 9, oil bucket, 10, sponge.
Embodiment
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
A kind of blower fan, comprise cylindrical shell 1, base 2, motor 3 and some flabellums 4, the inwall of described cylindrical shell 1 is provided with an annular groove 5, every sheet flabellum 4 is all installed with a mounting blocks 6 near one end of annular groove 5, described mounting blocks 6 is provided with a containing groove 61 towards the side of described annular groove 5, be provided with a ball 8 between described annular groove 5 and containing groove 61, described ball 8 is all fitted with the inwall of this annular groove 5 and containing groove 61.
The principle of such scheme is:
By above-mentioned setting, ball 8 is merely able to circle in annular groove 5, concentric with the rotary motion trace of flabellum 4, therefore, can't have influence on the normal rotation of flabellum 4; In addition, and fit completely due to the mounting blocks 6 on flabellum 4 and ball 8, therefore, the working principle of reference bearing, being equivalent to flabellum 4 two ends is obtained for fixing, so, just completely eliminate the defect of the unsettled setting in one end of flabellum 4 in prior art, the normal rotation of flabellum 4 can also be ensured simultaneously.
Further, also comprise a connecting ring 7, described connecting ring 7 penetrates every block mounting blocks 6 successively, to be fixed together by all mounting blocks 6.By arranging this connecting ring 7, each mounting blocks 6 can be made to go here and there together, serving the effect strengthening flabellum 4 stability further.
Further, a through hole 11 be communicated with cylindrical shell 1 outer wall is provided with in described annular groove 5.By arranging this through hole 11, can facilitate staff by this through hole 11 to lubricating oil filling in annular groove 5, reducing the frictional force of ball 8 and annular groove 5 and containing groove 61, extend wearing and tearing on the one hand, another conveniently also reduces noise.
Further, described through hole 11 is provided with a sponge 10 with the connectivity part of annular groove 5., can see from Fig. 3, Fig. 4, through hole 11 is arranged on directly over base 2, so when lubricating oil filling, lubrication axle can flow directly in annular groove 5, causes waste, by arranging this sponge 10, lubricant oil can first be absorbed by sponge 10, and as we can see from the figure, when ball 8 rotates in annular groove 5, be constantly can contact with sponge 10, so, ball 8 can be lubricated equally, meanwhile, turn avoid the waste of lubricant oil.
Further, the outer wall of described cylindrical shell 1 is provided with an oil bucket 9, and described oil bucket 9 is communicated with this through hole 11.By arranging this oil bucket 9, the interpolation of lubricant oil can be facilitated, meanwhile, suitably increase the size of oil bucket 9, can to struggle against a certain amount of lubricant oil of storage in 9 at oil, and due to the existence of sponge 10, lubricant oil also can't be very fast seepage go out, therefore, staff is after interpolation lubricant oil, again can need not add within a very long time, decrease workload.In addition, can also struggle against on 9 at oil and end cap is set, prevent the outflow of lubrication oil in oil bucket 9.
