Motor vibration-resisting device for vacuum dust collector

Abstract

The present invention provides a motor shock-proofing device for vacuum cleaner. Its structure includes motor with paddle-wheel cover external shell, the back surface of the motor external shell is equipped with bearing mounting frame. Said shock-proofing device also includes an independent motor support positioned in the self-body shell and separated from upper shell and lower shell. The supporting frames of two ends of said motor support and seal supporting frame can be used for fixing motor, in which the supporting frames are mounted on the exterior of the paddle-wheel cover external shell, and the bearing mounting frame is inserted into the fixing groove fixed on seal supporting frame. Said invention can effectively prevent vibration and vibration noise produced when the motor is rotated, and can raise the trustworthiness of the product.

Description

technical field [0001] The present invention relates to an invention of a vacuum cleaner, in particular to an invention related to an anti-vibration device for a motor used in a vacuum cleaner to prevent vibration transmission. Background technique [0002] The vacuum cleaner is an electronic cleaning machine that uses the attractive force generated by the motor to suck garbage and dust into the dust chamber together with the air for cleaning. [0003] There are two types of noise generated by vacuum cleaners. One is the vibration caused by the suction force generated by the rotation of the motor, and the vibration noise is transmitted to the vacuum cleaner body through the motor support parts. The other is the high-speed discharge flow driven by the motor. Air flow noise. [0004] Next, an existing motor support device for reducing vibration noise of a vacuum cleaner will be introduced. like Figure 1 to Figure 3 As shown, there are vacuum cleaners such as figure 1 As s...

AI Technical Summary

Problems solved by technology

[0013] In order to prevent vibrations on the motor 140, a shockproof cover 143 is installed on the outer peripheral surface of the impeller cover 141. However, in order to prevent the reversal caused by the reaction caused by the driving of the impeller, the upper and lower outer peripheral surfaces of the shockproof cover 143 are fixed on the upper and lower motor support frames 121. Therefore, the vibration is transmitted to the main body shell 101 through the upper and lower motor support frames 121, so the shockproof cover 143 cannot prevent the vibration caused
