Embodiment
Embodiment: as shown in figures 2-6, the invention provides a kind of specific embodiment of motor of dust collector, it comprises fan housing 10, determine impeller 20, be positioned at fan housing 10 and take turns 30 and turn assembly with determining of determining that impeller 30 is fixedly installed with the movable vane determining impeller 20 and be separated from each other setting, wherein fan housing 10 with determine impeller 20 mutually buckle be connected, determine impeller 20 and comprise housing and air channel 23, and air channel 23 and the mutual integrated injection molding of housing.Mutually two fitting surface diameters being connected of buckle are roughly the same with determining both impellers 20 for fan housing 10.
Fan housing 10 comprise be arranged on one end and be positioned at center intake grill 12, be positioned at the other end and towards the accepting groove 18 determining the extended multiple clasp arms 14 of impeller 20, be arranged on the draw-in groove 16 on each clasp arm 14 and circumferentially arrange, fan housing 10 is made up of nonmetallic material, be better with plastic materials, to reduce motor weight.
Housing is plastic materials, it comprise the center that is positioned at one end and with the fixing part 21 surely turning assembly axial restraint, be positioned at the other end and away from the exhaust outlet 22 of fan housing 10 one end, near fan housing 10 one end and with the fastener 24 of draw-in groove 16 phase buckle, be positioned at fixing part 21 side and for accommodating the host cavity 25 surely turning assembly at least partly, be provided with the mutual location fit with accepting groove 18 and the projection 26 of circumferentially arranging, 30 adjacent and main parts 27 be centered around outside fixing part 21 are taken turns with movable vane, between fixing part 21 and main part 27 and curved several blades 28 spaced, radially-inwardly shrink with one end main body 27 and to be formed and at least partly collecting turns the cover portion 29 of assembly 4 surely.Wherein fastener 24 preferably arranges main part 27 circumferentially, housing at least accommodates 1/2 axial length surely turning assembly in the axial direction, and 1/4 axial length surely turning assembly is at least accommodated in cover portion 29 in the axial direction, to collect rambling air-flow better, effectively cooling surely turning assembly, effectively reducing sound of the wind and noise.Main part 27 is connected with fan housing 10 buckle, and the fitting surface diameter of main part 27 is roughly the same with the fitting surface diameter of fan housing 10, and is greater than width or the diameter in cover portion 29.In the present invention, the sectional area in cover portion 29 is preferably rectangle or round-shaped, and inside has the inner chamber of hollow, surely turns assembly 4 to accommodate at least partly.Gap between adjacent two blades 28 forms the starting point in each air channel 23, and each air channel 23 axially extends, its axial extension is greater than 1/4 axial length surely turning assembly, circumferentially be looped around again the outside surely turning assembly simultaneously, each air channel 23 then unification is pooled in the inner chamber in cover portion 10, then extends termination to the terminal (exhaust outlet 22) in air channel 23.
Surely turn assembly to comprise in cylinder type also for metal shell 40, the rotor 42 be housed in shell 40, the stator 44 being arranged on shell 40 inwall and axial connection movable vane take turns the motor shaft 100 of 30 and rotor 42.One end of its housing 40 is inserted in host cavity 25 at least partly, and the other end of shell 40 is outside exposed through the inner chamber in cover portion 29, and exhaust outlet 22 surrounds shell 40.Wherein the direction sectional area of main part 27 to cover portion 29 along air-flow diminishes.The diameter of host cavity 25 is greater than the diameter of shell 40, and is less than width or the diameter in cover portion 29.
During work, as shown in Figure 4, air-flow enters in fan housing 10 from the intake grill 12 at fan housing 10 center, under the movable vane wheel 30 of High Rotation Speed drives, air-flow enters in the gap between each adjacent blades 28, enter in air channel 23 thus, because air channel 23 not only axially extends, simultaneously also along the arching trajectory of blade 28, air-flow cools along air channel 23 shell 40 surely turning assembly, simultaneously because fan housing and housing all adopt plastic materials, effectively can absorb the noise that air-flow produces, the then unified inner chamber entering into cover portion 29 of air-flow, because the inner chamber in cover portion 29 not only has larger space radial and axial, rambling air-flow is easy to by the air-flow accumulating one direction olderly flowage, and be in axial direction discharged to outside motor by exhaust outlet 22, make wind-guiding smooth and easy thus, reduce windage and loss, improve electric efficiency, reduce noise simultaneously.
Certain above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
