Motor noise reduction structure of dust collector and dust collector

Abstract

The invention discloses a motor noise reduction structure of a dust collector and a dust collector. The noise reduction structure comprises a mounting part used for mounting a motor on a dust collector and elastic components used for applying tension to the motor, wherein one end of each elastic component is connected to the mounting part; the other end of each elastic component is connected to the motor; the tension can offset the gravity of the motor; the number of the elastic components is two or more; the elastic components are uniformly distributed at the circumference of the motor; an included angle of 10-85 degrees is formed between the direction of the tension and the horizontal plane; the mounting part comprises a motor cover; the motor cover comprises an inner motor cover and an outer motor cover which are used for forming an accommodation space for the motor; the elastic components are connected to the outer motor cover or the inner motor cover; the lower part of the motor is suspended in the motor cover; the elastic components are tension springs. Through the motor noise reduction structure of the dust collector and the dust collector, a good motor noise reduction effect can be exerted.

Description

technical field [0001] The present application relates to the field of cleaning equipment, in particular to a motor noise reduction structure of a vacuum cleaner and the vacuum cleaner. Background technique [0002] With the development of society and the continuous improvement of people's living standards, vacuum cleaners have been used in more and more families as a household cleaning device. A vacuum cleaner is an electrical appliance that uses a motor to generate negative air pressure in a sealed housing to suck in dust or garbage. The main function of the current vacuum cleaner is to recycle and clean the dust and garbage on the floor, carpet, etc. in the home. [0003] With the development of technology, the functions of vacuum cleaners are constantly improving, and at the same time, the motor power of vacuum cleaners is also gradually increasing. Since the low-frequency noise of the vacuum cleaner mainly comes from the vibration during the rotation of the motor, as t...

AI Technical Summary

Problems solved by technology

In this patented technology, a compression spring is used to support the motor, so that under normal working conditions, the compression spring is compressed due to the gravity of the motor. However, when the motor rotates, there will be a force of circumferential rotation, and the main elasticity of the compression spring is The deformation direction is along the direction of gravity. When there is a force of circumferential rotation, the compression spring will be subjected to a force perpendicular to the direction of gravity, so that the compression spring will be deformed due to the influence of the circumferential force. The deformation reset ability is weak, so that the motor will oscillate in the circumferential direction under the influence of the circumferential force, resulting in poor overall noise reduction effect
