Problems solved by technology

[0002] At present, there is a lot of intake noise at the front end of the motor of the vacuum cleaner and the air inlet of the cabinet. Most of the existing solutions are to add sound-absorbing cotton to the air inlet. Although this method can improve the intake noise to a certain extent, The intake noise is still very loud, and the setting of sound-absorbing cotton increases the resistance of the gas flow path in the vacuum cleaner, which in turn affects the suction of the vacuum cleaner

Abstract

The invention provides a dust collector which comprises an enclosure, a dust cup and an air suction device, wherein the enclosure comprises an air inlet, an air inlet grille is disposed in the air inlet, the air inlet grille comprises multiple air inlets, and the multiple air inlets are distributed in a spiral or cellular or annular manner; the dust cup is disposed on the enclosure; and the air suction device is disposed in the enclosure and comprises a motor. According to the invention, the air inlet grille with the multiple air inlets distributed in the spiral or cellular or annular manner is applied, so that noise of the dust collector is reduced effectively. When the multiple air inlets are distributed in the spiral or annular manner, the noise generated from impact of air inlet vortexes on the air inlet grille can be reduced through effective cooperation with air inlet features brought by motor rotation of the dust collector; and when the multiple air inlets are distributed in a cellular manner, the vortex shape formed after airflows flow through the air inlet grille can be fully decomposed, so that impact noise brought by the airflows in the dust collector can be reduced, and users' experience can be improved.

Description

technical field [0001] The invention belongs to the technical field of dust removal appliances, and in particular relates to a vacuum cleaner. Background technique [0002] At present, there is a lot of intake noise at the front end of the motor of the vacuum cleaner and the air inlet of the cabinet. Most of the existing solutions are to add sound-absorbing cotton to the air inlet. Although this method can improve the intake noise to a certain extent, The intake noise is still very loud, and the setting of sound-absorbing cotton increases the resistance of the gas flow path in the vacuum cleaner, which in turn affects the suction of the vacuum cleaner. Contents of the invention [0003] The present invention aims to solve one of the technical problems existing in the prior art. [0004] To this end, an object of the present invention is to propose a vacuum cleaner. [0005] In view of this, according to an object of the present invention, a vacuum cleaner is proposed, in...
