Embodiment
Below in conjunction with accompanying drawing feature of the present invention and technology contents are elaborated.Only for reference and the explanation usefulness of accompanying drawing is not limitation of the present invention.
Fig. 1 is the elevational schematic view according to the flabellum of the first embodiment of the present invention.As shown in Figure 1, the invention provides a kind of flabellum and manufacture method thereof.Flabellum 1 comprises a wheel hub 10 and a plurality of this wheel hub 10 fan leaf 11 on every side that is arranged on.Wherein wheel hub 10 can be integrated with each fan leaf 11, is fixed as one after also can interconnecting again.Each fan leaf 11 can be fan leafs such as axial flow, centrifugal, diagonal flow type or cross-flow type, is used for producing air-flow, and to its channeling conduct, thereby plays the effect of general electric fan.
In the present invention, permeability magnetic material is injected in the material of making this flabellum 1, utilizes this permeability magnetic material on flabellum 1, to form the sector 12 that is constituted by many N, S magnetic pole.In the present embodiment, this sector 12 mainly is distributed in around the wheel hub 10 of flabellum 1 or its.As shown in Figure 2, in second embodiment of the invention, sector 12 is distributed on each fan leaf 11 of this flabellum 1, or is distributed in the end of each fan leaf 11.In addition, also can make whole flabellum 1 all contain described permeability magnetic material, or all comprise described permeability magnetic material on the whole flabellum face of each fan leaf 11 of this flabellum 1.This flabellum 1 can adopt ejection formation, die casting heat to bake type, die casting sinter molding or powder metallurgy sintered moulding etc. and make processing method, in the lump permeability magnetic material is injected in this flabellum 1, to finish the manufacturing moulding of this flabellum 1, make the flabellum of making 1 owing to the permeability magnetic material that it includes has magnetic, and need not additionally to install other magnet assembly, thereby dwindled the volume of flabellum.
Above-mentioned permeability magnetic material can be the material that iron-oxygen, SmCo system, Nd-Fe-B series or iron-cobalt-nickel etc. have magnetic.
Above-mentioned structure promptly is a magnetic flabellum of the present invention.
Fig. 3 is the schematic flow diagram according to the manufacture method of above-mentioned flabellum 1 of the present invention.As shown in Figure 3, the invention provides a kind of manufacture method of flabellum, this manufacture method is used for making above-mentioned flabellum 1, comprises the following steps:
A) according to flabellum 1 required sector 12, arrange its N, S magnetic pole; Wherein, the magnetic force direction of described sector 12 can be axially (Axis), radially (Radial), radiation direction (Radiation), two alienation directions (Two-direction) or extremely incorgruous direction directions such as (Multipolar); Its N, S magnetic pole can be arranged as isotropy (Isotropic), anisotropy (Anisotropy) or utmost point anisotropy (Multipolar) etc.
B) N, the S pole arrangement according to this sector 12 is injected into permeability magnetic material on this flabellum 1.In this step, permeability magnetic material can be that iron-oxygen, SmCo system, Nd-Fe-B series or iron-cobalt-nickel system are like preceding described material with magnetic.Permeability magnetic material is made into Powdered and becomes magnetic, and carry out material processed, be about to this permeability magnetic material, resin and plastic materials via mixing granulator, form the magnetic micelle, bake the processing that processing method is made in type, die casting sinter molding or powder metallurgy sintered moulding etc. with convenient employing ejection formation, die casting heat of carrying out subsequently.
C) sector 12 on this flabellum 1 is magnetized, so that it produces magnetic force.Described magnetization (magnetization) is with the flabellum 1 by the moulding of step b) institute, by energising permeability magnetic material is magnetized.Can utilize a magnetizing assembly to finish this step: promptly will to be placed on this magnetizing assembly by the flabellum 1 of step b) institute moulding earlier, again this magnetizing assembly to be applied voltage,, thereby make this flabellum 1 magnetization so that magnetizing assembly sparks and produce magnetic field.This magnetizing assembly can adopt unilateral magnetization (Single side multi-pole magnetization), resultant magnetization (Complesmagnetization), peripheral magnetization (Outer circumference multi-pole magnetization) or interior week magnetization methods such as (Inner circumference multi-pole magnetization) that described flabellum 1 is magnetized.Correspondingly, the magnetization configuration of described magnetizing assembly can be structures such as unilateral magnetization configuration, resultant magnetization structure, peripheral magnetization configuration or interior all magnetization configuration.
In addition, at above-mentioned steps b) before, can be earlier to sector 12 magnetic field analysis that carry out arranged evenly of different demands, to design its mould, and after finishing the exploitation and composition of this mould,, make the flabellum 1 of step b) to inject this mould again with permeability magnetic material heating fusion.
Above-mentioned steps promptly is the manufacture method of flabellum of the present invention.
Flabellum of the present invention and manufacture method thereof can shorten the manufacturing process of electric fan 1, make the flabellum of manufacturing have magnetic simultaneously, so need not this flabellum 1 is installed other magnet assembly again, can dwindle the volume of flabellum 1, help to satisfy in the practical application mini demand to fan, and can increase the number of magnetic poles of fan stator and coil writhing number etc., thereby improve the practicability of fan.
In sum, the present invention can reach the application target of expection really, solves the shortcoming that exists in the known technology, has novelty with creative, also is not disclosed use, meets the application for a patent for invention important document fully, now files an application according to Patent Law, please ratify.
The above is the preferred embodiments of the present invention, is not limitation of the present invention.All equivalences that those skilled in the art does according to specification of the present invention and accompanying drawing change and revise, and all are encompassed in the Patent right requirement scope of the present invention.
