Abstract

The utility model discloses a dust collector motor which comprises a housing. The lower end of the housing is provided with a wind cover. The central part of the wind cover is provided with a wind inlet. The inner cavity of the housing is provided with a stator and a rotor. The central part of the rotor is provided with a rotating shaft which is vertically arranged. The interior of the wind cover is provided with an impeller and an inducer, wherein the impeller is relatively fixed with the lower end of the rotating shaft, and the inducer is relatively fixed with the housing. The lower surface of the inducer is provided with a plurality of wind-guide vanes. The outer surface of the wind cover is provided with a positioning surface which is corresponding to the lower end faces of the wind-guide vanes. The lower end faces of the wind-guide vanes are respectively attached to the inner surface of the wind cover. The utility model aims at providing the dust collector motor which eliminates a gap between the inducer and the wind cover, thereby guaranteeing the stable operation.

Description

Motor of dust collector
Technical field
The utility model belongs to dust catcher technical field, particularly a kind of motor of dust collector.
Background technology
Motor of dust collector mainly comprises drive part and air passage portion, its air passage portion is provided with movable vane wheel and inducer, when movable vane wheel is rotated with high rotating speed, air is inhaled into from fan housing air inlet, by movable vane wheel, pressurizeed by passing enclosure interior after the centrifugal air duct of inducer, thereby provide heat radiation to the stator of drive part, rotor etc.But because motor is to position by housing side, be difficult to avoid occurring gap between inducer and fan housing, air-flow can enter into the gap of inducer and fan housing.As China Patent Publication No. CN 201763688U, a kind of gas channel of blower of cleaner is disclosed, in this utility model, owing to having gap between inducer and fan housing, during air-flow process this gap, can be subject to larger windage, thereby make motor produce larger vibration and noise, by the air-flow after this gap, also more easily at motor internal play, greatly affected the stability of motor operation.
Utility model content
The utility model is between inducer and fan housing, to exist gap to cause the deficiency of motor fluctuation of service in order to overcome in the motor of dust collector of prior art, thereby provides a kind of gap of eliminating between inducer and fan housing to guarantee stable motor of dust collector.
To achieve these goals, the utility model is by the following technical solutions:
A kind of motor of dust collector of the present utility model, comprise housing, the lower end of housing is provided with fan housing, fan housing middle part is provided with air inlet, in the inner chamber of housing, be provided with stator and rotor, rotor middle part is provided with the rotating shaft of vertical layout, in described fan housing, be provided with the relatively-stationary movable vane in rotating shaft lower end wheel and with the relatively-stationary inducer of housing, the lower surface of inducer is provided with some wind blades, the outer surface of fan housing is provided with the locating surface corresponding with position, wind blade lower surface, and the lower surface of described wind blade and fan housing inner surface fit tightly.Locating surface is also arranged on the corresponding position of fan housing outer surface, by location, fan housing inner surface and inducer is further compressed, thereby guarantee that both fit tightly elimination gap, guarantee that the centrifugal flow that moving vane rotary produces all flows to wind blade.So just, can greatly reduce vibration and noise that Air Flow produces, the air-flow of the inducer of simultaneously flowing through is also comparatively stable, has reduced the play of gas at motor internal, guarantees motor stabilizing operation.
As preferably, described movable vane wheel goes out to be provided with the flange of downward bending at air inlet, and described fan housing is provided with the annular groove corresponding with flange position at air inlet place, and the bottom of annular groove is provided with the barrier layer matching with flange.Barrier layer can be crammed the space between flange and annular groove, avoids the air flow air inlet through movable vane wheel, has improved the efficiency of motor.
As preferably, described housing lower end outward forms flange, and the lower surface of flange is fixed with support, and described support inner side is fixedly connected with the inner side of inducer.The location that guarantees like this inducer is comparatively firm, guarantees the stable of air channel.
As preferably, described housing upper end is provided with some steam vents.The air-flow entering in housing is discharged by steam vent.
Therefore, the utlity model has following beneficial effect: eliminate the gap between fan housing and inducer, reduce the play of air-flow in motor internal, vibration and noise while having reduced motor operation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure, rotating shaft 1, rotor 2, stator 3, support 4, inducer 5, wind blade 5a, movable vane wheel 6, flange 6a, barrier layer 7, annular groove 8, fan housing 9, locating surface 9a, housing 10, steam vent 10a.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of motor of dust collector, comprise housing 10, the lower end of housing is provided with fan housing 9, fan housing middle part is provided with air inlet, in the inner chamber of housing, be provided with stator 3 and rotor 2, rotor middle part is provided with the rotating shaft 1 of vertical layout, in fan housing, be provided with the relatively-stationary movable vane in rotating shaft lower end wheel 6 and with the relatively-stationary inducer 5 of housing, the lower surface of inducer is provided with some wind blade 5a, the outer surface of fan housing is provided with the locating surface 9a corresponding with position, wind blade lower surface, and the lower surface of wind blade and fan housing inner surface fit tightly.Movable vane wheel goes out to be provided with the flange 6a of downward bending at air inlet, fan housing is provided with the annular groove corresponding with flange position 8 at air inlet place, and the bottom of annular groove is provided with the barrier layer 7 matching with flange.Housing lower end outward forms flange, and the lower surface of flange is fixed with support 4, and support inner side is fixedly connected with the inner side of inducer.In addition, housing upper end is provided with some steam vent 10a.
When actual motion, motor of dust collector energising, rotor and rotating shaft are together rotated, thereby drive moving wheel rotation, air is the centrifugal air duct through movable vane wheel from fan housing air inlet, flow in inducer, and the wind blade by inducer flow in housing, thereby the stator of enclosure interior, rotor etc. are dispelled the heat, finally by the steam vent of housing upper end, discharge.This motor of dust collector positions it by the locating surface of fan housing end, during location to fan housing with determine impeller and compress, thereby eliminated gap between the two, prevent air-flow play in motor, improve the stability that motor moves.
