Embodiment
Below in conjunction with accompanying drawing and specific embodiment the centrifugal fan that the utility model proposes is done further explain.According to following explanation and claims, advantage of the utility model 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, aid illustration the utility model embodiment's purpose lucidly.
The core concept of the utility model is; A kind of centrifugal fan is provided, comprises 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; Said protection plectane is arranged on said some flabellums; Said wheel hub, some flabellums and the protection plectane structure that is formed in one, this centrifugal fan drives the rotation of some flabellums through the rotation of wheel hub, and the protection plectane is along with some flabellums rotate together; Realize the air draft effect of this centrifugal fan; 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; The integrated formed structure of this centrifugal fan is convenient for carrying it and transports, and has simplified its installation process, and 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 of the wheel hub of the centrifugal fan that the structural representation of the centrifugal fan that Fig. 1 provides for the utility model embodiment, Fig. 2 provide for the utility model embodiment.
The utility model embodiment 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, and said protection plectane 3 is arranged on said some flabellums 2; Said wheel hub 1, some flabellums 2 and protection plectane 3 structure that is formed in one; When this centrifugal fan work, rotate the some flabellums 2 of drive through drive hub 1 and rotate, 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, make 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 integrated formed structure of this centrifugal fan is convenient for carrying it and transports, and has simplified its installation process, and 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.
