Description
Technical field
The utility model relates to a kind of parts of vacuum cleaner, is specifically related to a kind of Cyclonic separating apparatus of vacuum cleaner.
Background technology
In vacuum cleaner, in order effectively dust to be separated from air-flow, various forms of cyclone separators are used in beginning widely.For example, the device that PCT patent application WO 98/35602 discloses on a kind of Cyclonic vacuum duster, the air intake that has dust tangentially is arranged at the top of cyclone chamber, center of top is air stream outlet (negative pressure source), air-flow rotates under centrifugal action after tangentially entering in the cyclone chamber, under the part dust to sedimentation separation, air-flow moves upward from central authorities simultaneously, discharges from the air stream outlet at top through filter.Though said structure can be realized dust separation to a certain degree, the dust that settles down is driven and enters once more in the ascending air by air-flow easily, causes the dust content in the ascending air big thus, and filter easily stops up, and needs often to clean.
For addressing the above problem, secondary separation device has appearred, promptly second level cyclone separator is set again at the air stream outlet rear of above-mentioned cyclone separator, simultaneously, increase the aperture of filter, tiny dust can pass through filter, to alleviate the stopping state of filter.Yet the problem that one-level cyclone separative efficiency is not high is difficult to solve all the time, simultaneously, how the secondary whirlwind is set, and makes its existing dust removing effects preferably, can adapt to the ever-reduced trend of dust catcher volume again, also is a problem that urgency is to be solved.
Summary of the invention
The utility model purpose provides a kind of one-level cyclonic separation efficient height, and one, two two stage cyclone devices are provided with rationally, can effectively realize the Cyclonic separating apparatus of dust separating vacuum cleaner.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Cyclonic separating apparatus of vacuum cleaner, comprise the upstream cyclone body, collecting chamber and a plurality of downstream whirly mechanism, described upstream cyclone body comprises rotational symmetric Whirlwind barrel, air inlet and air stream outlet, air stream outlet is positioned at the Whirlwind barrel center of top, described air inlet be positioned at Whirlwind barrel the bottom and with Whirlwind barrel wall arranged tangential, Whirlwind barrel top is provided with the dust export that is communicated with collecting chamber top, the air stream outlet periphery is provided with the taper guard that the awl point is provided with downwards in the Whirlwind barrel, described air inlet and dust export are positioned at outside the guard, described downstream whirly mechanism is around the collecting chamber setting, and the air stream outlet of upstream cyclone body tangentially is communicated to each downstream whirly mechanism respectively through flow dividing structure.
Optimized technical scheme, described flow dividing structure is, the top of described Whirlwind barrel and collecting chamber is provided with shunting layer, the air stream outlet upper end open of Whirlwind barrel is in shunting layer, be provided with the flow manifold of each downstream whirly tube of a plurality of tangential connections in the shunting layer, the central authorities of each downstream whirly tube are respectively arranged with the gas outlet that is communicated with air outlet.
Further technical scheme is provided with the thin grey collecting chamber of arranging around collecting chamber, and described downstream whirly tube is positioned at thin grey collecting chamber top, and each whirly tube bottom, downstream is taper, and conical lower portion central authorities have the hole that connects thin grey collecting chamber.
In the technique scheme, the wall of described Whirlwind barrel, collecting chamber, thin grey collecting chamber and the shunting layer structure that is formed in one, its bottom is sealedly and fixedly connected by bottom sealing ring and syndeton and bottom, and the top is sealedly and fixedly connected by venthole sealing ring and venthole installing plate.
Described air inlet is positioned at Whirlwind barrel bottom 1/3rd altitude ranges; Described upstream cyclone body is arranged at a side of collecting chamber.
Operation principle of the present utility model is: the air-flow that has dust enters the upstream cyclone body from air inlet, move upward at the Whirlwind barrel inside spin, dust throws away collecting chamber from the dust export of upper end, the air-flow that has a small amount of thin ash is upwards discharged by air stream outlet through the grid of taper guard, evenly enter each downstream whirly tube through flow dividing structure, in the whirly tube of downstream, do the efficient cyclone motion, dust separated decline under centrifugal action enters thin grey collecting chamber, do quiet air-flow and rise, discharge through air outlet and enter motor from the columned gas outlet of central authorities.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1. upstream of the present utility model cyclone body air inlet is positioned at the bottom, thereby the cyclonic motion direction is consistent with negative pressure source suction direction, dust can be thrown out of by dust export for the helical movement preferably and one side from the top, owing to the centrifugal action of air-flow, has reached the effect of efficient separation;
2. the taper guard in the cyclone body of upstream, because most advanced and sophisticated the sealing, avoided the direct rising of central fluidizing gas, effectively guarantee the screw of air-flow, thereby dust is difficult for being inhaled in the guard, need not add filtration separately in the guard grid, thereby blockage problem can not take place, and can effectively reduce the pressure loss, the efficiency of dust collection height;
3. the utility model is provided with a plurality of downstreams whirly tube, can effectively separate the fine dust of being taken out of by air-flow.
