Abstract

The utility model discloses a novel assembled DC dust collector motor, comprising a housing at one end, a rotor which is contained in the housing and is provided with a rotating shaft, a stator which is contained in the housing and surrounds the rotor, a fan housing which is disposed at the other end and is provided with an air inlet, a moving impeller contained in the fan housing, and a fixed impeller which is disposed below the moving impeller and is provided with a plurality of ducts. The utility model is characterized in that the housing is provided with a flange which abuts against the fixed impeller; a part of the duct directly exposes to the outside by the flange. By exposing a part of the duct to the outside, the utility model has advantages of simplifying assembling process; reducing cost; ensuring the smoothness of a duct; enhancing the efficiency of an air blower.

Description

The direct current motor of dust collector of novel assembling

Technical field

The utility model relates to a kind of direct current motor of dust collector of novel assembling.

Background technology

The motor of conventional little direct-current high-efficiency dust catcher, as Fig. 1, its casing 1 with decide impeller 3 and can't directly be connected, but locate impeller 3 by an end cap 2, and fix connection between end cap 2 and the casing 1 by screw 4, this mode assembly technology complexity not only increases cost but also wind path has some setbacks, and influences fan efficiency.

Summary of the invention

The utility model purpose is: the direct current motor of dust collector that a kind of novel assembling is provided.

A technical scheme of the present utility model is: a kind of direct current motor of dust collector of novel assembling, it comprises: be positioned at an end casing, be contained in casing and have a rotating shaft rotor, be contained in casing and surrounding rotor and the stator that is provided with, be positioned at the other end and have air inlet fan housing, be housed in fan housing the movable vane wheel, be positioned at below the movable vane wheel and have the impeller of deciding in several air channels, wherein said casing has and decides impeller against a flange that contacts, and this flange allows the part in air channel directly exposed outside at least.

Flange described in the utility model is a ring-type, and its diameter is less than the diameter of deciding impeller.

One end of rotating shaft described in the utility model is arranged with a lining, and this lining is step-like.

Step-like lining described in the utility model stretches into in the nut.

The spin locking direction of nut described in the utility model is opposite with the direction of rotation of movable vane wheel.

One end of casing described in the utility model is provided with the flange of a ring-type, and its diameter is less than the diameter of deciding impeller.

Flange described in the utility model by at least one screw with decide impeller and interfix.

The utility model advantage is: exposed outside by air passage portion, simplify assembly technology, and reduce cost and guarantee that wind path is smooth and easy, strengthen fan efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the cutaway view of prior art shaft connected mode;

Embodiment

Embodiment: shown in figure 2-3, the utility model provides a kind of specific embodiment of direct current motor of dust collector of novel assembling, it comprises the casing 10 that is positioned at an end and has flange 12, be contained in casing 10 and have a rotating shaft 100 rotor 50, be contained in casing 10 and surrounding rotor 50 and the stator 60 that is provided with, be positioned at the other end and have air inlet (not label) fan housing 20, be housed in fan housing 20 movable vane wheel 30, be positioned at movable vane and take turns 30 belows and have deciding impeller 40 and being positioned at the upper and lower trim ring 32 that movable vane is taken turns 30 times sheets of several air channels 42.Its shaft 100 and movable vane wheel 30 fixes by a nut 22 and is connected, and nut 22 has T shape hole, and it is opposite that the spin locking direction of nut 22 and movable vane are taken turns 30 direction of rotation, and upper and lower trim ring 32 includes the trim ring hole 320 that is positioned at the center.

Casing 10 is the cylinder of an end opening and interior hollow, the employing metal material is made, and flange 12 is positioned at the openend of casing 10, profile in the form of a ring, its diameter is less than the diameter of deciding impeller 40, and greater than the diameter of casing 10, the part that makes the air channel 42 of deciding impeller 40 be positioned at flange 12 outsides is exposed outside, guarantee to discharge by the exposed excessively air channel 42 of the movable vane wheel 30 part air communication of coming out, and the part air-flow enters into casing 10 because of the air channel that is positioned at flange 12 inside parts, flow through gap between rotor 50 and the stator 60, the air outlet 102 from casing 10 flows out at last.This flange 12 with decide impeller 40 by plane contact, and by several screws 44 at least and decide impeller 40 and interfix.Realize good fixing thus, and be convenient to miniaturization, densification, low cost, and it is more smooth and easy to make that internal gas flow flows.

One end of rotating shaft 100 is arranged with the lining 34 that is step-like, and this lining 34 is at movable vane wheel 30 and decide between the impeller 40, through the hole of upper and lower trim ring hole 320 and movable vane wheel 30 and stretch in the T shape hole of nut 22 into, to strengthen fixing of rotating shaft 100 and movable vane wheel 30.

The utility model is simplified assembly technology by exposed outside by air passage portion, reduces cost and guarantees that wind path is smooth and easy, strengthens fan efficiency.

Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
