The beneficial effects of the invention are as follows：This case will be imported by setting baffle after the air rectification entered by motor upper end
To exhaust outlet, the generation of turbulent flow and turbulent flow in wind scooper is effectively reduced, so that because of gas when effectively reducing exhaust outlet discharge air
Turbulent flow and turbulent flow and the noise that produces；By setting shunting wall that the two strands of air-flows entered by two exhaust outlets are carried out rectification, make
Two strands of air-flows uniformly converge, and can effectively prevent the generation of turbulent flow and turbulent flow in air-out chamber, avoid the generation of noise；Drawn by setting
Block and wind-guiding convex block are flowed, further to suppress the generation of turbulent flow and turbulent flow, to achieve the purpose that noise reduction.

Embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
As shown in Figs. 1-3, the dust catcher air channel structure for being used to reduce noise of an embodiment is listed in this case, it includes：
Wind scooper 1, it has the baffle 101 for separating the air-flow that motor in dust catcher 2 is discharged；
Main air duct 3, it is communicated in the bottom of wind scooper 1；
Wall 4 is shunted, it is located at the upstream end of main air duct 3, for guiding the first individually concurrent flow of the air-flow being separated
Converge to the downstream of main air duct 3 and finally；
Wherein, the bottom of wind scooper 1 is equipped with the exhaust outlet 102 of connection main air duct, for the air-flow being separated is divided
The upstream end of main air duct 3 is not guided into individually.
Wherein, the inner surface of main air duct 3 is arranged to fairing curved surface.
Wherein, wind scooper 1 has a cover body 103, which is located at the outlet air end of motor 2, and equipped with receiving air-flow
Cavity；
Wherein, baffle 101 is located between 2 outer wall of 103 inner wall of cover body and motor, for discharge motor in dust catcher 2
Air-flow separates.
Wherein, baffle 101 is preferably elastic component.
Wherein, the side for shunting wall 4 is preferably provided with several grooves 401.Groove 401 is used for have just enter into main air duct 3
Air-flow buffering is provided, it is disorderly to reduce to a certain extent to prevent air-flow in the upstream end local compression of main air duct 3 and collision
Stream and sinuous flow.
Wherein, 401 surface of groove is further preferably provided with sound absorbing layer, further to reduce noise.
Wherein, shunt wall 4 and one end of 3 downstream of main air duct is provided with drainage block 5.Drainage block 5 is used for
The confluence of air-flow provides guiding, to suppress turbulent flow and sinuous flow.
Wherein, the downstream of main air duct 3 is additionally provided with multiple wind-guiding convex blocks 6.Wind-guiding convex block 6 can be used for cutting air-flow
Cut, wind noise, to reduce the generation of low frequency noise, is reduced the invasion to user's sense of hearing from " toot " be changed into " z z z " sound.
The principle of noise reduction for the dust catcher air channel structure that this case proposes is as follows：Motor 2 is opened, and air-flow pours into 1 cover body of wind scooper
In 103 cavity, by being separated by baffle 101, air-flow be divided into two-way and respectively from 102 row of exhaust outlet of each cavity to
The Upstream section of underlying main air duct 3；And since the Upstream section of main air duct 3 has shunting wall 4, two strands of air-flows are split
Wall 4 guides abreast flow forward, and the confluence of two strands of air-flows is finally realized at the terminal drainage block 5 of shunting wall 4, and most
Discharged eventually from main air duct 3 outside dust catcher.This case will air flow partition, first rectification, converge afterwards by way of, reduce between air-flow
The turbulent flow and turbulent flow produced by random collision, has effectively played noise reduction and has improved the purpose of efficiency.
