Abstract
The utility model discloses a dust collector motor with a sealing structure, at least comprising a fixed impeller, a bracket and a sealing member. The fixed impeller contains a fixed impeller hole and a hole lateral margin arranged on the periphery of the fixed impeller hole; the bracket is mounted below the fixed impeller and contains a bracket bump; the bracket bump extends upward in the fixed impeller hole; and the sealing member is located between the fixed impeller and the bracket. By setting the sealing member between the fixed impeller and the bracket, the utility model ensures no air leak of an airway, is simple in structure, reduces the wind loss and improves the efficiency of the motor.
Description
Technical field
The utility model relates to a kind of motor of dust collector with hermetically-sealed construction.
Background technology
Motor of dust collector generally includes plastics and makes and contain deciding impeller and being installed in the metallic support of deciding impeller below of an axis hole, wherein metallic support with decide impeller axis hole quality of fit and have relatively high expectations, otherwise leak out easily, and plastic deformation also takes place in axis hole easily that decide impeller, cause sealing not good, make the motor of dust collector decrease in efficiency.
Summary of the invention
The utility model purpose is: provide a kind of motor of dust collector with hermetically-sealed construction, to improve electric efficiency.
A technical scheme of the present utility model is: a kind of motor of dust collector with hermetically-sealed construction, it comprises at least: contain and decide impeller bore and be arranged on deciding impeller and being installed in the support of deciding the impeller below and containing a support boss of the hole lateral margin of deciding the impeller bore periphery, wherein this support boss upwards stretches into this and decides in the impeller bore, and it further comprises at the seal of deciding between impeller and the support.
Seal described in the utility model and is set on the support boss ringwise.
The bottom of the lateral margin of hole described in the utility model contacts with seal.
The inboard of the lateral margin of hole described in the utility model contacts with seal.
The utility model advantage is: by being arranged on the seal of deciding between impeller and the support, do not leak out in the assurance air channel, simple in structure, reduces windage loss, improves efficiency of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the cooperation figure of the utility model support and sealing ring;
Fig. 2 decides the partial schematic sectional view of impeller, support and sealing ring for the utility model;
Wherein: 10, decide impeller; 12, decide impeller bore; 14, hole lateral margin; 20, support; 22, support flank; 24, support boss; 30, seal; 240, bracket holes.
Embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of specific embodiment with motor of dust collector of hermetically-sealed construction, it comprises at least: contain and decide impeller bore 12 and be arranged on deciding impeller 10 and being installed in the support 20 of deciding impeller 10 belows and containing a support boss 24 of the hole lateral margin 14 of deciding impeller bore 12 peripheries, wherein this support boss 24 upwards stretches into this and decides in the impeller bore 12, and having a bracket holes 240 in the center, it further comprises at the seal of deciding between impeller 10 and the support 20 30.
Seal 30 ringwise, i.e. sealing ring, and being set on the support boss 24.In the present embodiment, preferably, the bottom of hole lateral margin 14 contacts with seal 30, to guarantee to decide the sealing between impeller 10 and the support 20.Be understandable that seal 30 also can contact with the inboard of hole lateral margin 14, can guarantee to decide the sealing between impeller 10 and the support 20 equally.
The utility model is by being arranged on the seal of deciding between impeller and the support, and do not leak out in the assurance air channel, simple in structure, reduces windage loss, improves efficiency of motor.
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.
