Embodiment Construction

[0020] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0021] refer to Figure 1 to Figure 2 , corresponding to a vacuum cleaner in a preferred embodiment of the present invention, which is mainly used for cleaning in households and other special places, and includes a housing part 10 and a motor 12 located in the housing part 10 . An air inlet 25 is arranged below the motor 12 , and an air outlet 24 is arranged on the casing part 10 . Furthermore, the housing part 10 includes a lower cover 15 and a top cover 14 mounted on the lower cover 15 .

[0022] further reference Figure 3 to Figure 4 The above-mentioned vacuum cleaner also includes an air outlet duct 34, which is arranged between the air inlet 25 and the air outlet 24 of the vacuum cleaner. The air outlet duct 34 is provided with a power chamber 11 and at least one sound-abneuating chamber co...

Abstract

The invention discloses an exhaust air flue of a dust collector. The exhaust air flue is arranged between an air inlet and an air outlet of the dust collector, wherein a power chamber and at least one silencing chamber communicated with the power chamber are arranged in the exhaust air flue; a motor is arranged inside the power chamber; the airflow direction of the power chamber and the airflow direction inside at least one silencing chamber are turned and changed in the positions of a three-dimensional space; and a turbulence device is also arranged on the exhaust air flue. The airflow of the turbulence device collides with the airflow of at least one silencing chamber. The exhaust air flue of the dust collector is compounded with a plurality of noise attenuating measures; the space of the chamber is fully utilized; and the exhaust air flue is wide in silencing frequency range, ultra-quiet in overall machine, and good in sense of ears.

Description

technical field [0001] The invention relates to an air outlet duct of a vacuum cleaner. Background technique [0002] The structure of the vacuum cleaner mainly includes: an air inlet, a dust removal chamber, a motor, an air outlet, and an air outlet duct arranged between the air inlet and the air outlet. In households and special places, such as hotels, offices, etc., it is required to set the vacuum cleaner to be silent. In the prior art, noise reduction measures are usually taken in the air outlet duct. One of the measures is to use the principle of resistive noise reduction to form the air outlet duct into a single-space flip structure; The wind duct is set to directly discharge the wind after one revolution. Therefore, the noise reduction measures for the air outlet duct of this type of vacuum cleaner are relatively simple, the frequency range of the noise reduction is not wide, the noise of the whole machine is high, and the ear feeling is not good. Contents of the...
