Abstract

The invention relates to a dust collector and an air outlet filtering part of the dust collector. The air outlet filtering part comprises a main body, a first denoising part and a second denoising part, wherein an air outlet cavity is formed in the main body, air inlet holes and an air outlet are formed in the main body, and the air inlet holes, the air outlet cavity and the air outlet communicatewith each other in sequence; the first denoising part is arranged in the air outlet cavity, and comprises a plurality of primary denoising parts, the plurality of primary denoising parts are arrangedat intervals along the flowing direction of air flow in the air outlet cavity, and the plurality of primary denoising parts are positioned on the flow path of the air flow; and the second denoising part is connected to the air outlet in an adaptive manner and comprises a secondary denoising part, and a plurality of denoising channels communicating with the air outlet cavity are formed in the secondary denoising part. For the dust collector and the air outlet filtering part of the dust collector provided by the invention, relatively low noise is generated at the air outlet.

Description

technical field [0001] The invention relates to the field of smart technology, in particular to a vacuum cleaner and an air outlet filter thereof. Background technique [0002] The vacuum cleaner in the prior art is generally equipped with a power assembly and an air outlet filter. Under the action of the power assembly, the airflow flows into the interior of the vacuum cleaner and is discharged from the air outlet after being filtered by the air outlet filter. However, the power components also emit sound waves when they are working, and the sound waves are propagated through the flow of the airflow and generate huge noise at the air outlet, resulting in poor user experience. Therefore, how to reduce the noise at the air outlet of the vacuum cleaner has become an urgent problem to be solved. Contents of the invention [0003] Based on this, it is necessary to provide a vacuum cleaner and an air outlet filter which can reduce the noise at the air outlet in order to solve...
