Motor noise-reducing structure of dust collector

Abstract

The invention discloses a motor noise-reducing structure of a dust collector. The motor noise-reducing structure of the dust collector comprises a motor inner cover, wherein the motor inner cover is installed at the outer side of a dust collector motor, a first airflow cavity is formed between the motor inner cover and the dust collector motor, and the first airflow cavity is internally provided with a spiral flow guide plate; a motor outer cover, wherein the motor outer cover is installed at the outer side of the motor inner cover, a second airflow cavity is formed between the motor outer cover and the motor inner cover, the motor outer cover is a double-layer structure, the motor outer cover comprises an outer cover inner ring and an outer cover outer ring, a cavity is formed between theouter cover inner ring and the outer cover outer ring, the cavity is internally provided with a plurality of separating plates, and the separating plates are used for separating the cavity to form aplurality of noise-reducing cavities; and a shock ring, wherein the shock ring is circle-shaped, the shock ring is installed between the motor outer cover and a dust collector housing. The solution uses the noise-reducing structure, has the functions of sound insulation, shock absorption and noise reduction, and is capable of solving the technical problem that the noise of a current dust collectoris larger.

Description

technical field [0001] The invention relates to the field of noise reduction, in particular, the invention relates to a motor noise reduction structure of a 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. When the vacuum cleaner is in use, the motor in the motor inner cover rotates at a high speed, and a negative air pressure is generated in the sealed main body of the vacuum cleaner to absorb external dust. During the operation of the motor, the motor in the motor inner cover rotates at high speed, which causes the inner cover of the motor to vibrate. Because the inner motor cover and the outer cover of the motor are in direct contact, the inner cover of the motor drives the outer cover of the motor to vibrate, and the outer cover of the motor It is fixed with the vacuum cleaner shell. During the...

Problems solved by technology

[0004] Another object of the present invention is to provide a motor noise reduction structure of a vacuum cleaner. A spiral deflector is arranged between the motor inner cover and the motor outer cover to extend the transmission path of the airflow noise, and the motor outer cover is set to double Multi-layer structure, which is equipped with multiple sound-absorbing chambers, which further reduces the noise. At the same time, the motor cover and the vacuum cleaner shell are connected by a shock-absorbing ring, which reduces the noise generated by vibration and solves the technical problem of high noise in the existing vacuum cleaner.
