Shock-absorption noise-reduction connecting structure of dust aspirator motor

Abstract

A shock-absorption noise-lowering connection structure for a dust collector motor comprises a motor support and bracket arranged in a motor chamber; a rubber sealing block connected with one end of the motor; a fixed rubber ring arranged on the other end of the motor; and a motor cover arranged outside the motor casing and comprising a main body including two opposite small arc surfaces connected with two opposite large arc surfaces, an end face with a square hole on the side, and an arch-shaped silencer comprising the extended sections of the two large arc surfaces, wherein the arc-shaped silencer has a hollow cavity and is provided with air inlets on two inner sides and air outlets on two outer sides; the rubber sealing block comprises a location pillar on the one side of disc connection, a convex stage on the other side, a square body and a plurality of clamps on the convex stage; and an arc-shaped rubber cushion is arranged between the motor cover on the other end of the motor and the fixed rubber ring. The motor cover with the arc-shaped silencer arranged outside the motor casing can lower the noise and absorb shock.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a vacuum cleaner motor connection structure which is provided with an arc-shaped muffler outside a vacuum cleaner motor housing to reduce noise and shock. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside ...

AI Technical Summary

Problems solved by technology

The rubber sealing block of this structure is only connected by inserting two positioning columns into the holes on the end face of the motor, which is not reliable.

And the sealing is not good
