Plate 330 is located on the air outlet 260 of the second motor cover 240, and aerofluxuss web plate 330 has multiple aerofluxuss mesh 331.Thus, lead to
Cross the aerofluxuss web plate 330 being located on air outlet 260, as the ground floor exhaust structure of exhaust apparatus, for reducing from air inlet dress
Put the flow velocity of exhaust gas in 200, shunt it, and change its frequency.But behind exhaust passage 320, further to gas
Rate of flow of fluid carries out reduction of speed, and changes its frequency further.
Alternatively, the cross sectional shape of aerofluxuss mesh 331 is circle, polygon, ellipse or other shapes.Further,
On the exhaust airstream direction of aerofluxuss web plate 330, the section of aerofluxuss mesh 331 is gradually increased, not shown.
Preferably, multiple aerofluxuss mesh 331 are evenly distributed on aerofluxuss web plate 330, as shown in Figure 2.Optional show at one
In example, multiple aerofluxuss mesh 331 are evenly distributed with multiple rows of multiple row on aerofluxuss web plate 330.In another optional example, multiple
Aerofluxuss mesh 331 is evenly distributed with the annular shape that is radially spaced on aerofluxuss web plate 330.
According to some embodiments of the present invention, exhaust apparatus 300 can also include aerofluxuss outer housing, not shown, described row
Gas outer housing is set in the outside of described hood and has aerofluxuss collar extension, limits between described aerofluxuss outer housing and described hood
The outer air duct being connected with described exhaust passage by described aerofluxuss collar extension.Thus, by arranging aerofluxuss outer housing, exogenous wind can be passed through
Exhaust passage is extended by road further, thus reducing flow velocity to air draught, and changes air-flow frequency further.
Below with reference to Fig. 1-Fig. 2, vacuum cleaner according to embodiments of the present invention is described.
Vacuum cleaner according to embodiments of the present invention, including：For collecting dust collect plant 100, air intake installation 200 and of dust
Exhaust apparatus 300, wherein exhaust apparatus 300 are the exhaust apparatus of the vacuum cleaner in above-described embodiment.Alternatively, dust collect plant
100 include dust bag or dust pocket.
As shown in figure 1, air intake installation 200 include motor 210 and the first sheathed successively from inside to outside motor cover 220,
Two motor cover 240, motor 210 is provided in the first motor cover 220 of innermost layer, and the first motor cover 220 passes through air inlet 250
Connect with dust collect plant 100, common restriction exhaust passage 270, the second motor between the first motor cover 220 and the second motor cover 240
Cover 240 has air outlet 260.Alternatively, be provided with the air inlet 250 between dust collect plant 100 and the first motor cover 220 for
Filter the filter screen 110 of dust.
Thus, motor 210 rotates generation negative pressure in the first motor cover 220, and the air with dust is mussily sucked
In dust collect plant 100, at air inlet 250, dust is filtered, and air enters in the first motor cover 220.Now, by motor 210
The disorderly gas sucking flows in air channel 270, then discharges from the air outlet of the second motor cover 240, and passes through exhaust passage 320
After be discharged in air.
Vacuum cleaner according to embodiments of the present invention, due to extending the air channel length of air flow enough, thus stabilize
Air current flow, and greatly reduce noise.In addition, according to the vacuum cleaner of the present invention, the simple low cost of structure.
Referring again to Fig. 1-Fig. 2, the work process of vacuum cleaner according to embodiments of the present invention is specifically described.
First, motor 210 rotates generation negative pressure in the first motor cover 220, and the air with dust is mussily sucked
In dust collect plant 100, at air inlet 250, dust is filtered, and air enters in the first motor cover 220.
As shown by the arrows in Figure 1, air-flow is sucked by motor 210 at air inlet 250, flows in the first motor cover 220, edge
The inwall flowing of the first motor cover 220, and flow to air outlet 260 in air channel 270 from the first gas outlet 221.
Now, air draught is discharged from the aerofluxuss web plate 330 being located at air outlet 260, aerofluxuss web plate 330 has multiple
Aerofluxuss mesh 331, thus reducing the flow velocity of exhaust gas from air intake installation 200, shunts it, and changes its frequency.So
Afterwards, the gas through aerofluxuss web plate 330 flows in exhaust passage 320, and the cross-sectional area due to exhaust passage 320 gradually becomes
Greatly, changing flow velocity or the frequency of air draught, thus greatly reducing noise and the vibration of air draught generation itself, entering
And the muting function of vacuum cleaner is become apparent from.
