Motor noise reduction structure of vacuum cleaner and vacuum cleaner

Abstract

The present application discloses a motor noise reduction structure of a vacuum cleaner and the vacuum cleaner. The noise reduction structure includes: a mounting part, which can install the motor on the vacuum cleaner; an elastic element that applies tension to the motor, and the elastic element One end is connected with the installation part, and the other end is connected with the motor; the pulling force can offset the gravity of the motor. The number of the elastic elements is at least two. The elastic elements are evenly distributed in the circumferential direction of the motor. The angle between the direction of the pulling force and the horizontal plane is 10°-85°. The installation part includes a motor cover. The motor cover includes a motor inner cover and a motor outer cover, and the motor outer cover and the motor inner cover form a storage space for accommodating the motor; the elastic element is connected to the motor outer cover or the motor inner cover. The lower part of the motor is suspended in the motor cover. The elastic element is a tension spring. The motor noise reduction structure of the vacuum cleaner and the vacuum cleaner of the present application can achieve a better motor noise reduction effect.

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...

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
