Embodiment
Below in conjunction with accompanying drawing and specific embodiment the centrifugal fan that the present invention proposes is done further explain.According to following explanation and claims, advantage of the present invention and characteristic will be clearer.What need explanation is, accompanying drawing all adopts the form of simplifying very much and all uses non-ratio accurately, only in order to convenient, the purpose of the aid illustration embodiment of the invention lucidly.
Core concept of the present invention is; A kind of centrifugal fan is provided; Comprise wheel hub, some flabellums and protection plectane, said some flabellums identical angle at interval are located on the said wheel hub in the same way, and said protection plectane is arranged on said some flabellums; Said wheel hub is that detachable is connected with the Placement of said some flabellums; This centrifugal fan drives the rotation of some flabellums through the rotation of wheel hub, and the protection plectane is realized the air draft effect of this centrifugal fan along with some flabellums rotate together; The protection plectane that is arranged on some flabellums has been protected the flabellum in this centrifugal fan effectively; Make flabellum in the process of rotation, can not produce deformation or out of service because of collision or friction easily, and the design of protection plectane can make the dust and other impurities that falls on this centrifugal fan wheel hub and the flabellum obviously reduce in this centrifugal fan, therefore also need not often clean to keep the clean and tidy and workmanship of this centrifugal fan; Dust and foreign material that detachable wheel hub in this centrifugal fan makes some flabellums and the protection plectane on flabellum be removed together easily and to wash accumulation; And can carry out maintenance to the flabellum that disassembles, keeping the clean and tidy and workmanship of whole centrifugal fan, the said structure design through this centrifugal fan can make its workmanship at work guarantee to some extent; Carrying and easy for installation, and the excellent protection measure makes and has also obtained prolongation the working life of this centrifugal fan.
Please refer to Fig. 1 and Fig. 2, the structural representation the when wheel hub of the centrifugal fan that the structural representation of the wheel hub of the centrifugal fan that Fig. 1 provides for the embodiment of the invention, Fig. 2 provide for the embodiment of the invention splits.
The embodiment of the invention provides a kind of centrifugal fan; Comprise wheel hub 1, some flabellums 2 and protection plectane 3; Said some flabellums 2 identical angle at interval are located on the said wheel hub 1 in the same way; Said protection plectane 3 is arranged on said some flabellums 2; Said wheel hub 1 is that detachable is connected with the Placement of said some flabellums 2, when this centrifugal fan work, rotates the some flabellums 2 of drive through drive hub 1 and rotates; Protection plectane 3 is along with some flabellums 2 rotate together; Realize the air draft effect of this centrifugal fan, the protection plectane 3 that is arranged on some flabellums 2 has been protected the flabellum 2 in this centrifugal fan effectively, makes flabellum 2 in the process of rotation, can not produce deformation or out of service because of collision or friction easily; And the design of protection plectane 3 can make the dust and other impurities that falls on this centrifugal fan wheel hub 1 and the flabellum 2 obviously reduce in this centrifugal fan; Therefore also need not often clean to keep the clean and tidy and workmanship of this centrifugal fan, the detachable wheel hub 1 in this centrifugal fan makes some flabellums 2 reach dust and the foreign material that the protection plectane 3 on flabellum 2 can be removed together easily and wash accumulation, and can carry out maintenance to the flabellum 2 that disassembles; To keep the clean and tidy and workmanship of whole centrifugal fan; Said structure design through this centrifugal fan can make its workmanship at work guarantee to some extent, carrying and easy for installation, and the excellent protection measure makes and has also obtained prolongation the working life of this centrifugal fan.
Further; Said wheel hub 1 is fixed in said some flabellums 2 times through screw 6; Every flabellum 2 in said some flabellums 2 all is fixed in this flabellum 2 times through two screws 6 with wheel hub 1; The staff that fixedly makes through carry out wheel hub 1 with screw 6 can be easily disassembles manpower and time when having reduced dismounting with the flabellum 2 and the protection plectane 3 of this centrifugal fan together.
Further; The Manufacturing material of said wheel hub 1, some flabellums 2 and protection plectane 3 is a magnesium; Magnesium is one of the lightest structural metallic material, have again strength and stiffness height, damping and amortization and machinability good, be easy to advantage such as recovery, both at home and abroad magnesium alloy is widely used in during automobile industry or space flight makes; With loss of weight, energy-conservation, reduction pollution; Improve environment, and magnesium also there is very big application prospect at other field, uses magnesium to make that this centrifugal fan of being made up of these parts has light weight, damping property is good, fatigue resistance is good, be difficult for advantages such as aging as the material of wheel hub 1, some flabellums 2 and protection plectane 3; Improve the workmanship of this centrifugal fan, also prolonged its working life.
Further, said protection plectane 3 be shaped as annular, be processed as annular through protecting plectane 3, make and leave certain gap can be observed this centrifugal fan constantly for the staff working condition in the centre of protection plectane 3.
Further; Institute also comprises first baffle plate 4 and second baffle 5; Said first plate washer 4 is arranged on the inner circumference of protection plectane 3 of said annular, and said second baffle 5 is arranged on the excircle of said protection plectane 3, through such design make protection plectane 5 can be better stopping through first baffle plate 4 and second baffle 5; When this centrifugal fan is not worked; Dust is stayed on the said protection plectane 5, and can not caused dust to be slipped on flabellum 2 or the wheel hub 1, influence the workmanship of this centrifugal fan because of not stopping from protection plectane 3.
Obviously, those skilled in the art can carry out various changes and distortion to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
