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 noise reducing type dust catcher air draft mechanism 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；
The inner wall both sides of main air duct 3 are equipped with the crushing block 5 with arc-shaped curved surface in the river outlet of air-flow.Crushing block 5 is used for
Guide air-flow and reduce the effective diameter of main air duct 3, make the increase of its wind pressure to extrude air-flow, so as to ensure do not increasing
On the premise of wind is made an uproar, increase deflation rate, improve efficiency.
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 accumulation 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, 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 draft mechanism 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 in the terminal for shunting wall 4, by crushing block 5
Pressurization, air-flow is quickly discharged from main air duct 3 outside dust catcher.This case by by air flow partition, first rectification, rear converge
The mode of stream, reduces the turbulent flow produced between air-flow by random collision and turbulent flow, has effectively played noise reduction and has improved efficiency
Purpose.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
