Description

Dust collector motor capable of reducing noise

Technical Field

The utility model belongs to the field of motors, and particularly relates to a noise-reducing motor of a dust collector.

Background

The utility model provides a method for effectively reducing the noise of a motor, which aims to solve the problem that the noise generated by the high-speed running and high-speed wind speed of the motor is high and can seriously affect the surrounding environment in the using process of equipment with the motor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a dust collection motor in the prior art is high in noise, and provides a novel noise-reducing dust collector motor which has the characteristic of low noise.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: dust catcher motor of degradable making an uproar, fan housing and motor casing including interconnect, be equipped with the motor in the motor casing, be equipped with in the fan housing with the impeller that the pivot of motor is connected, the impeller is equipped with the apron, impeller and apron between be provided with and fall the sponge of making an uproar, it includes first sponge board and second sponge board to fall the sponge of making an uproar, first sponge board is equipped with a plurality of through-holes that run through, second sponge inboard portion equidistance is equipped with a plurality of recesses.

The motor shell is characterized in that a plurality of flat keys are radially arranged on the inner wall of the motor shell, the flat keys are distributed in a spiral shape, and spiral channels are formed among the flat keys.

The flat key and the motor shell are integrally arranged.

The motor casing bottom uncovered be provided with the flange, the flange on be provided with a plurality of bleeder vents, fan housing and flange sealing connection.

The air holes are provided with movable cover plates.

The sponge of making an uproar is equipped with the quad slit, the impeller be equipped with quad slit complex erection column.

Has the advantages that:

through being provided with the sponge of making an uproar that falls between stator vane wheel and apron, reduce dust catcher motor noise, the sponge of making an uproar that falls adopts bilayer structure to increase life.
