Simultaneously as shown in Figure 7, cover in the above between 220 bottom surface and control of dust tube 210 top and formed certain space, therefore constituted assembly space 270.Assemble 270 li in space at this, will assemble by described each guiding tube 254 flow air that makes progress, and these air are mobile towards the output channel 222 of described upper cover 220.
The air that has broken away from collecting unit of dust 200 by delivery outlet 224 will flow in the electric machine assembly 140.
Below, the fuselage of vacuum cleaner of the present invention and the effect of collecting unit of dust describe.
At first, sucking the process that air and foreign matter purify with reference to Fig. 3 to Fig. 9 for the vacuum cleaner with said structure describes.
The user makes electric machine assembly 140 entrys into service by operating portion 82, and vacuum cleaner produces suction.Utilize this suction, suck air outside and foreign matter by nozzle body 50.
From nozzle body 50 leaked-in airs and the inside of foreign matter by prolonging pipe 60 and being connected flexible pipe 70 inflow fuselages 100.The air that flows into fuselage 100 inside enters the inside of described collecting unit of dust 200 by suction guide structure 212.
The air and the foreign matter that enter collecting unit of dust 200 inside rotate along guide barrel 242 inner faces, and the air of rotation is by the inside of the airport 244a` inflow filter 244a of filter 244a.
At this moment, airborne foreign matter will be deposited in the inside of the 3rd dust-collecting cavity 260 or the 1st dust-collecting cavity 248.Specifically, under the effect of flowing velocity and inertia force, enter and be deposited in the inside of described the 3rd dust-collecting cavity 260 by the part in the foreign matter that is comprised in the air that sucks guide structure 212 quick inflow guide barrel 242 inside by inflow entrance 260`.
Then, continue along the airborne foreign matter of the inner face rotation of guide barrel 242, the bigger foreign matter of volume of airport 244a` that can't be by described filter 244a will be fallen the downside of guard shield 244b, be stacked in the 1st dust-collecting cavity 248.
The air that flows into collecting unit of dust 200 inside moves with concentrically ringed track to the downside of guard shield 244b, and it flows at last by preventing flow plate 244c blocking-up.Then, move to the upside of guard shield 244b once more, by filter 244a.At this moment, the big relatively foreign matter of weight can't move to the top of guard shield 244b again and will be stacked into the inside of the 1st dust-collecting cavity 248 after the bottom that moves to guard shield 244b.
The air of inflow filter 244a inside becomes fan-shaped with foreign matter in the diffusion inside of guiding channel 246, flows into each whirly portion 252 respectively.The air that flows into whirly portion 252 inside spiral rotation under the guiding of the guide portion (not shown) that forms of the upper end of whirly portion 252 again.
Inside in whirly portion 252, air and foreign matter rotation also descend, and at this moment more to the lower end of whirly portion 252, the speed of the air that is rotated will be fast more.
At this moment, along with the inner face rotation of air along whirly portion 252 descends, on the central part of whirly portion 252, form ascending air.This phenomenon is identical with the typhoon eye phenomenon.Therefore, ascending air flows to the upside of control of dust tube 210 by several guiding tube 254 guiding, accumulates in and assembles in the space 270.
In this process, the fine foreign matters of together rotating at the inside and the air of whirly portion 252 can't rise under inertia force and action of centrifugal force, and is separated to the downside of whirly portion 252.Therefore, these fine foreign matters will be deposited in the 2nd dust-collecting cavity 256 inside.
Simultaneously, gather the inside that the air of assembling 270 inside, space will flow into upper cover 220,, discharge by delivery outlet 224 through output channel 222.
As shown in Figure 9, between described delivery outlet 224 and electric machine assembly 140, form connecting pipings 280, flowed into the head 140` of electric machine assembly 140 from the cleaned air passes of collecting unit of dust 200 outputs along connecting pipings 280.
The air that flows into the head 140` of electric machine assembly 140 is discharged once more by the Lower Half of electric machine assembly 140, by the delivery outlet 122` inflow gas deflation assembly 126 of electric machine stand 122.
The air that flows into gas deflation assembly 126 when (not representing among the figure), after further purifying, is discharged to the side (right side side) of vacuum cleaner fuselage 100 through discharge filter.That is, air and foreign matter flow into from the place ahead of fuselage 100, by gas deflation assembly 126 guiding, are expelled to the right side side of fuselage 100.
Through above-mentioned process, when piling up foreign matter in the inside of the 1st dust-collecting cavity 248 and the 2nd dust-collecting cavity 256, open lower cover 230 discarded foreign matters.Promptly, because control of dust tube 210, the rear end that has particularly formed the dust-collecting cavity 210 of the 3rd dust-collecting cavity 260 is formed by transparent material, therefore as shown in Figure 3, be installed at collecting unit of dust 200 under the state of fuselage 100, the user can confirm to be deposited in the amount of the foreign matter of the 3rd dust-collecting cavity 260 accurately, when having assembled a certain amount of foreign matter, open lower cover 230 is removed foreign matter.
It is as follows to specify the method for removing foreign matter.When pressing lower cover button 262, the fixed hook 232 of lower cover 230 will break away from and cover button 262.At this moment, lower cover 230 serves as axially to rotate down to open with cover hinge 234, and the foreign matter of the 1st dust-collecting cavity 248 and the 2nd dust-collecting cavity 256 inside will be fallen the below, thereby go out of use.
