But the ubiquitous problem of the vacuum cleaner in the related art is that the noise is very loud when working
When the ground brush is vacuuming on the ground, because of the good dust removal effect, the suction pressure of the brush head must be very large, which means that the air outlet of the ground brush must fit well with the ground. The wind speed of the tuyere is very fast, and the sound of the airflow entering the air duct is also very loud, which brings great inconvenience to the user

The invention provides an air duct system for a dust collector and the dust collector. The air duct system comprises a bottom shell, an upper cover, a silencing cavity and an opening device; the bottom shell is provided with an air inlet; the upper cover is arranged on the bottom shell and a mounting cavity is formed by encircling of the upper cover and the bottom shell; an air duct is formed in the mounting cavity, and the air duct is communicated with the air inlet; the silencing cavity is communicated with the air duct; and the opening device is arranged in the mounting cavity and is used for controlling connection and disconnection between the silencing cavity and the air duct. According to the air duct system for the dust collector, which is provided by the invention, the silencing cavity is formed in the air duct of the dust collector and the opening device is arranged in the mounting cavity to control connection and disconnection between the silencing cavity and the air duct and achieve opening and closing of the silencing cavity of the dust collector, and thus, a user can select whether to open the silencing cavity according to the condition of the cleaned ground, so that noise generated when the dust collector cleans a carpet is reduced, and on the basis of ensuring a dust collection effect of the dust collector, comfort when the user uses the product is greatly improved.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to an air duct system of a vacuum cleaner and the vacuum cleaner. Background technique [0002] At present, as vacuum cleaners become more and more common in household use, consumers pay more and more attention to operating experience. However, the common problem of the vacuum cleaners in the related art is that they are very noisy during operation. When the ground brush is vacuuming on the ground, because of the good dust removal effect, the suction pressure of the brush head must be very large, which means that the air outlet of the ground brush must fit well with the ground. The negative impact brought by this time is that the ground brush will enter The wind speed of the tuyere is very fast, and the sound of the airflow entering the air duct is also very loud, which brings great inconvenience to the user. Contents of the invention [0003] In order to solve at least one o...
