Specific implementation mode
Embodiment：As shown in figures 2-6, the present invention provides a kind of specific embodiments of motor of dust collector comprising fan housing
10, determine impeller 20, be separated from each other the movable vane wheel 30 of setting in the fan housing 10 and with impeller 20 is determined and set with the fixation of impeller 30 is determined
That sets determines to turn component, and wherein fan housing 10 is mutually snapped connection with impeller 20 is determined, and determines impeller 20 and includes shell and air duct 23, and air duct
23 with the mutual integrated injection molding of shell.Fan housing 10 and determine two mating surface diameters that the two of impeller 20 mutually snaps connection substantially
It is identical.
Fan housing 10 include setting at one end and centrally located air inlet 12, be located at the other end and towards determine impeller 20 extend
The multiple clasp arms 14 being arranged, the card slot 16 being arranged on each clasp arm 14 and the container 18 being arranged circumferentially about, fan housing
10 are made of nonmetallic materials, are preferable with plastic material, to reduce motor weight.
Shell is plastic material comprising positioned at one end center and with the fixed part 21, the position that turn component axial restraint surely
In the other end and far from 10 one end of fan housing air outlet 22, close to 10 one end of fan housing and with 16 phase of card slot buckle fastener 24,
Turn the host cavity 25 of component surely, equipped with being mutually located with container 18 positioned at the side of fixed part 21 and at least partly accommodating
Coordinate and be arranged circumferentially about protrusion 26, main part 27 adjacent with movable vane wheel 30 and being centered around the outside of fixed part 21, be located at it is solid
Determine between portion 21 and main part 27 and several arc-shaped spaced blades 28 and one end main body 27 are radially-inwardly received
Contracting forms and at least partly accommodates the cover portion 29 for turning component 4 surely.Wherein fastener 24 is preferably set up on the circumference of main part 27,
Shell at least accommodates 1/2 axial length for turning component surely in the axial direction, and at least receiving is fixed in the axial direction for cover portion 29
1/4 axial length for turning component is effectively cooled down, effectively with preferably collecting rambling air-flow to turning component surely
Reduce sound of the wind and noise.Main part 27 is snapped connection with fan housing 10, the mating surface of the mating surface diameter and fan housing 10 of main part 27
Diameter is roughly the same, and more than the width or diameter of cover portion 29.The sectional area of cover portion 29 is preferably rectangular or round in the present invention
Shape, and it is internal with hollow inner cavity, turn component 4 surely at least partly to accommodate.Gap between adjacent two blade 28 is formed
The starting point in each air duct 23, and each air duct 23 axially extends, axial extension is axial more than turn component surely 1/4
Length, while it being circumferentially looped around the outside for turning component surely again, then each air duct 23 is uniformly pooled to the inner cavity of cover portion 10
In, then extend to the terminal (air outlet 22) in air duct 23 and terminate.
Surely turn component to include in cylinder type and be shell 40, the rotor 42 being housed in shell 40, setting made of metal
In the stator 44 of 40 inner wall of shell and the motor shaft 100 of axial connection movable vane wheel 30 and rotor 42.Wherein one end of shell 40
Be at least partially inserted into host cavity 25, and the other end of shell 40 pass through cover portion 29 inner cavity and it is exposed outside, and air outlet
22 surround shell 40.Wherein main part 27 becomes smaller to cover portion 29 along the direction sectional area of air-flow.The diameter of host cavity 25 is more than
The diameter of shell 40, and less than the width or diameter of cover portion 29.
When work, as shown in figure 4, air-flow is entered from the air inlet 12 at 10 center of fan housing in fan housing 10, in high speed rotation
Movable vane wheel 30 drive under, air-flow enters in the gap between each adjacent blades 28, thus enters in air duct 23, due to wind
Road 23 is not only along axially extending, while also along the arching trajectory of blade 28, and air-flow is along air duct 23 to turning the outer of component surely
Shell 40 is cooled down, simultaneously because fan housing and shell are all made of plastic material, can effectively absorb noise caused by air-flow, and
Air-flow uniformly enters the inner cavity of cover portion 29 afterwards, since the inner cavity of cover portion 29 not only has larger space radial and axial,
Rambling air-flow is easy to be aggregated into the air-flow of one direction olderly flowage, and is in axial direction discharged to by air outlet 22
Except motor, thus make wind-guiding smooth, reduce windage and loss, improves electric efficiency, while reducing noise.
Certainly the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with technique
People can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to this hair
The equivalent transformation or modification that the Spirit Essence of bright main technical schemes is done, should be covered by the protection scope of the present invention.
