Ground brush assembly of dust collector and dust collector with ground brush assembly

Abstract

The invention discloses a ground brush assembly of a dust collector and the dust collector with the ground brush assembly. The ground brush assembly of the dust collector comprises a ground brush bottom shell, a ground brush upper cover and an air channel upper cover, wherein the ground brush bottom shell is provided with an air inlet; the ground brush upper cover is arranged on the ground brush bottom shell and an air channel is limited between the ground brush upper cover and the ground brush bottom shell; the air channel is communicated with the air inlet; the air channel upper cover is arranged between the ground brush upper cover and the ground brush bottom shell; a plurality of ventilation holes, which are distributed at intervals, are formed in the ground brush upper cover; each ventilation hole is communicated with the air channel. According to the ground brush assembly of the dust collector, disclosed by the embodiment of the invention, the ground brush upper cover with the plurality of ventilation holes is arranged between the ground brush bottom shell and the ground brush upper cover, so that rapid dirty air flow can be dispersed and becomes slow; meanwhile, high-frequency sound waves in the dirty air flow are also attenuated, so that the aim of reducing noises is realized. The ground brush assembly of the dust collector is simple and compact in structure; the sealing and the dust removing efficiency of a ground brush are not influenced and the silencing aim can be realized, so that the user experience is good.

Description

technical field [0001] The invention relates to the technical field of cleaning machinery, and more particularly, to a floor brush assembly of a vacuum cleaner and a vacuum cleaner having the same. Background technique [0002] As vacuum cleaners become more and more common in household use, consumers no longer only meet the vacuuming function, but pay more and more attention to the operating experience. At present, the vacuum cleaners on the market generally have the problem of high working noise, and the ground brush is a very important source of the working noise of the vacuum cleaner. When the floor brush is vacuuming on the ground, in order to ensure a good dust removal effect, the negative pressure of the brush head of the floor brush must be large, which means that it is necessary to ensure that the air inlet of the floor brush air duct has a good fit with the ground. As a result, the wind speed at the air inlet of the ground brush will be very rapid, which will incr...

AI Technical Summary

Problems solved by technology

At present, the vacuum cleaners on the market generally have the problem of high working noise, and the ground brush is a very important source of the working noise of the vacuum cleaner.

When the floor brush is vacuuming on the ground, in order to ensure a good dust removal effect, the negative pressure of the brush head of the floor brush must be large, which means that it is necessary to ensure that the air inlet of the floor brush air duct has a good fit with the ground. As a result, the wind speed at the air inlet of the ground brush will be very rapid, which will increase the sound of the airflow entering the air duct.

In the related art, the air duct of the floor brush assembly is limited by the assembly of the air duct upper cover and the air duct lower cover, and the noise is reduced by setting the inner wall of the air duct into a smooth curved surface. It has improved, but it still cannot eliminate the high-frequency sound waves in the noise, the work noise is loud, and the user experience is poor
