Description

The dust-separating appliance of vacuum cleaner
Technical field
The present invention relates to a kind of dust-separating appliance that is applied on the vacuum cleaner.
Background technology
In the prior art, the dust-separating appliance of vacuum cleaner comprises the two stage cyclone separator, upstream cyclone is the poor efficiency separator, band dirt air-flow enters upstream cyclone separating chamber from the air inlet of upstream cyclone, the upstream cyclonic separation is indoor carry out cyclonic separation after, the bottom of upstream cyclone separating chamber is isolated and gathered to oarse-grained dust from air-flow, the air-flow that has little dust then enters in the cyclone separator of downstream, and in the cyclone separator of downstream, efficiently separate, make little dust from air-flow, separate.
Because the separative efficiency of upstream cyclone is very low; so also need between upstream cyclone and downstream cyclone separator, to be provided with a dust block board and mesh filter usually; make that big ash is further separated, to alleviate the work load of downstream cyclone separator.But after dust block board and mesh filter are set, cause atmospheric pressure lost more, and dust also easily stops up the mesh filter, make the whole work efficiency of dust catcher reduce.
Summary of the invention
The object of the invention provides a kind of dust-separating appliance of vacuum cleaner, and it can improve the separative efficiency of upstream separator under the prerequisite that reduces atmospheric pressure lost.
For achieving the above object, the technical solution used in the present invention is: a kind of dust-separating appliance of vacuum cleaner comprises upstream separator and downstream separator;

The specific embodiment
Shown in accompanying drawing 1-accompanying drawing 9, a kind of dust-separating appliance of vacuum cleaner, comprise upstream separator, downstream separator, upstream separator has air inlet 5, described downstream separator has air outlet 3, band dirt air-flow enters the upstream separator from air inlet 5, through after the primary separation, the air-flow that has thin dirt is through enter in the downstream separator communicating pipe 5, and in downstream separator, enter secondary separation, final clean gas flow amount is discharged from air outlet 3, and the vacuum motor that enters dust catcher then is indoor.
Described upstream separator is the poor efficiency separator, and this upstream separator comprises upstream whirlwind tube 4, is positioned at the mozzle 8 of described upstream whirlwind tube 4, constitutes upstream cyclone chamber 10 between described upstream whirlwind tube 4 and the mozzle 8; The arranged outside of described upstream whirlwind tube 4 has outer cylinder body 1, be connected with at least two dividing plates 6 between the outer wall of described upstream whirlwind tube 4 and the inwall of outer cylinder body 1, described dividing plate 6 is divided into upstream dust storage chamber 11, downstream dust storage chamber 13 and air intake passage 2 with the space between upstream whirlwind tube 4 and the outer cylinder body 1; Air intake passage 2 is connected with air inlet 5, and described air inlet 5 tangentially is opened in the bottom of upstream whirlwind tube 4; The sidewall upper portion of described upstream whirlwind tube 4 has breach 12, and this breach 12 is communicated with described upstream cyclone chamber 10 and upstream dust storage chamber 11.
Band dirt air-flow tangentially enters the bottom of upstream cyclone chamber 10 through air inlet 5; and rotate around mozzle 8 on the screw; when air motion arrives breach 12 places; because the madial wall of upstream whirlwind tube 4 disappears to the active force of dust; cause the suffered centripetal force of dust in the air-flow to lose; the bulky grain dust promptly can be from breach 12 centrifugation in upstream dust storage chamber 11; its separative efficiency is higher; isolate in the air-flow behind the big dust and only contain a small amount of little dust, the air-flow that carries little dust then can enter into downstream separator along mozzle 8.
Described mozzle 8 inserts in the upstream cyclone chamber 10 from the upper oral part of upstream whirlwind tube 4, and the lowest positions of mozzle 8 need be lower than described breach 12 residing positions, so that entrained big dust throws away from breach 12 earlier in the air-flow, air-flow turns back from the top of upstream whirlwind tube 4 and enters the mozzle 8 then, can prevent to carry the air-flow gap crossing 12 of big dust and directly screws in the mozzle 8.The following side of described mozzle 8 is provided with the grid 9 that can filter dust, with the dust that carries in the further separation bubble, can alleviate the work load of downstream separator.And the outer contour of described grid 9 constitutes turbination, makes cyclonic motion to guarantee air-flow.
In the preferred embodiment that the present invention habitually practised; described downstream separator is arranged in the upside of upstream separator; so that the air-flow of discharging from upstream separator arrives the downstream separator through the shortest gas circuit; and the downstream dust storage chamber 13 of downstream separator adopts dividing plate 6 to separate with the upstream dust storage chamber of upstream separator 11; make upstream dust storage chamber 11 be convenient to be arranged at the outside of upstream whirlwind tube 4; and be easy to gap 12 on the whirlwind tube 4 of upstream, make the bulky grain dust successfully from breach 12, to be separated in the upstream dust storage chamber 11 in whirlwind tube 4 outsides, upstream.
Downstream separator is an efficient cyclone, described downstream separator comprises a plurality of downstream whirlwind tubes 7 that are frustroconical that are set up in parallel, the infraoral of each downstream whirlwind tube 7 is positioned at downstream dust storage chamber 13, the air-flow of isolating behind the big dust is discharged from mozzle 8, after be assigned in each downstream whirlwind tube 7.In accompanying drawing 3, accompanying drawing 7-accompanying drawing 9, all can see the position distribution situation of downstream whirlwind tube 7, described downstream whirlwind tube 7 inserts in the downstream dust storage chamber 13 that is separated out by dividing plate 6, and described a plurality of downstreams whirlwind tube 7 is arranged along one section circular arc around upstream whirlwind tube 4, its can guarantee between the upper port of the tangential inlet of each upstream whirlwind tube 4 and mozzle 8 distance about equally, make air-flow be assigned to equably in each downstream whirlwind tube 7.In each downstream whirlwind tube 7, air-flow is done the high-speed screw motion, entrained little dust just is separated and drops out in the downstream dust storage chamber 13 from the infraoral of downstream whirlwind tube 7 in the air-flow, the top of each downstream whirlwind tube 7 all has air outlet, clean gas flow is just discharged and is compiled from the air outlet 3 of downstream whirlwind tube 7, final clean gas flow enters in the vacuum motor chamber (usual means on the dust catcher is not so adopt accompanying drawing to describe in detail) of dust catcher.
Shown in accompanying drawing 5, accompanying drawing 7, described a plurality of downstreams whirlwind tube 7 is positioned at the outside of upstream whirlwind tube 4, the space that it can effectively utilize between upstream whirlwind tube 4 and outer simplified 1 so that the compact conformation of whole dust-separating appliance is reasonable, thereby reduces the volume of whole device.
