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

Disclosed is an air outlet duct of a suction cleaner, which is arranged between an air inlet and an air outlet of the suction cleaner. The air outlet duct is provided with a power chamber and at least one anechoic chamber in communication with the power chamber. A motor is arranged in the power chamber. The air flow direction of the power chamber and the air flow direction in the at least one anechoic chamber are turned over and changed in a three dimensional spatial location. The air outlet duct is also provided with a spoiler device, and the air flow of the spoiler device and the air flow of the at least one anechoic chamber collide mutually. The air outlet duct of the suction cleaner is compounded with various noise reduction measures, and takes full advantage of the chamber space, so that the range of a silencing frequency is wide, the noise of the whole machine is low, and kept at a tolerable level.

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...
