With reference to Fig. 3 and Fig. 8, grid members 370 prevents that isolated big relatively dirt particle is by air outlet slit 350 dischargings in first cyclone chamber 310.Grid members 370 comprises grid body 371 and is connected to the skirt section 372 of the lower end of grid body 371 that grid body 371 has formation a plurality of through holes thereon.Grid body 371 cylindrical shapes and have unlimited upper end.Extend from the circumference of the lower end of grid body 371 in the lower end closed of grid body 371 and skirt section 372.Skirt section 372 prevents that collecting the dirt particle of collecting in first dust collection part 230 of shell 200 at dust refluxes.
With reference to Fig. 5 and Fig. 8, second cyclone 400 is arranged according to certain intervals around plate shape supporter 401, is formed with opening at the center of plate shape supporter 401.When second cyclone 400 inserted in the dust collection shell 200, second cyclone 400 was arranged around the periphery of first chamber outer wall 320 of first cyclone 300.
Each of second cyclone 400 comprises second chamber outer wall 420 and second inlet 430 that is used to form second cyclone chamber 410.Second chamber outer wall 420 in the form of a truncated cone, its diameter diminishes gradually to the lower end.Second chamber outer wall, 420 both ends opens.Comprise not that the air of isolated tiny dirt particle descends in first cyclone 300 in second cyclone chamber 410, form vortex, thereby the tiny dirt particle that comprises in air is isolated eccentrically and the lower end discharging by second chamber outer wall 420.Second inlet 430 is formed on the upper end of opening wide of second chamber outer wall 420, is used for and will guides to second cyclone chamber 410 from first cyclone, 300 air discharged.The air of being isolated dirt in second cyclone chamber 410 eccentrically covers 510 air discharging guide channel 513 dischargings by air inlet/give vent to anger.
As shown in FIG., no matter the quantity of second cyclone 400 what and how arrange, second cyclone 400 is all arranged along the periphery of first cyclone 300 equably according to the structure of first cyclone 300.More particularly, in traditional Cyclonic dust-collecting appratus shown in Figure 1, second cyclone 30 does not allow to be formed on the specific region 60 that is provided with air intake duct 13.But, in multi cyclone dust-collecting apparatus according to the present invention, the air intake duct 210 that is used to suck surrounding air is set at the bottom that dust is collected shell 200, and first inlet 360 that is connected to air intake duct 210 that is used to pass air into first cyclone 300 is arranged on the inboard of first chamber outer wall 320.Therefore, can arrange a plurality of second cyclones 400 and not limit their quantity or their arrangement that this has improved the dust collection efficiency of multi cyclone dust-collecting apparatus 100 greatly.
In order to form vortex in first cyclone 300, air must flow into from the upper lateral part of first chamber outer wall 320.For this reason, tube connector 330 guiding air move to its top from the bottom of first cyclone 300, and separate guide 405 and air guide member 340 will guide to the sidepiece of first chamber outer wall 320 to form vortex by tube connector 330 air discharged.Therefore, can effectively utilize initial revolution space owing to contain the air of dirt, thereby when described air flowed into first cyclone 300, it can promptly rotate, and prevented the pressure loss and kept constant suction according to constant centrifugal force.
Refer again to Fig. 3, cap unit 500 comprises whirlwind lid 520, filter member 530 and the containment member 540 that air inlet/give vent to anger is covered 510, is arranged in described air inlet/gives vent to anger and cover 510 tops.
With reference to Fig. 6 and Fig. 8, air inlet/give vent to anger is covered 510 and will be guided to each second cyclone 400 from the air that first cyclone 300 gives off.Air inlet/give vent to anger is covered 510 and is comprised the plate shape air inlet/lid 511 of giving vent to anger, air guide passage 512 and the air discharging guide channel 513 with predetermined altitude.Air guide passage 512 about the center of the air inlet/lid 511 of giving vent to anger along radial arrangement.Air guide passage 512 makes second inlet, 430 circulations of the air outlet slit 350 and second cyclone 400 of first cyclone 300.Air discharging guide channel 513 is along vertical direction formation and have predetermined altitude.In second cyclone chamber 410 of second cyclone 400, isolate the air rising of tiny dirt particle eccentrically and discharge guide channel 513 dischargings by air.Cover 510 when being connected with second cyclone 400 when air inlet/give vent to anger, the part of each of air discharging guide channel 513 is inserted in each of second cyclone 400.
With reference to Fig. 7 and Fig. 8, whirlwind lid 520 covers air inlet/give vent to anger and cover 510, and comprises that whirlwind lid 521, lid inlet 522, lid export 523 and cover plate 524.For brevity, Fig. 7 has shown the part of the filter member 530 of Fig. 3.Whirlwind lid 521 is the drum with predetermined altitude, and has the lid inlet 522 that is formed on its bottom centre, is used for and will converges to together and draw described air from second cyclone, 400 air discharged by discharging guide channel 513.Whirlwind lid 521 has the lid outlet 523 that is used for discharged air that is formed on its sidepiece.In this embodiment, lid inlet 522 is formed on the bottom centre of whirlwind lid 521 and covers the sidepiece that outlet 523 is formed on whirlwind lid 521.But this not should be understood to restrictive.Cover plate 524 is connected with the upper end of whirlwind lid 521.Rise by lid inlet 522 inhaled airs,, disperse then and descend with cover plate 524 collisions.The air that descends is discharged into the outside through filter member 530 and by lid outlet 523.
Air inlet/give vent to anger cover 510 and whirlwind lid 520 can form mutually, perhaps form separably.
Though in the present embodiment, filter member 530 is disposed between the lid inlet 522 and lid outlet 523 of whirlwind lid 520, and this should not be understood as that restrictive.In another embodiment, filter member 530 be set at air inlet/give vent to anger cover 510 and whirlwind lid 520 between.Filter member 530 is used for filtering the very tiny dirt particle that comprises from second cyclone, 400 air discharged, so, even filter member 530 be set at air inlet/give vent to anger cover 510 and whirlwind lid 520 between the air movement passage in, also can reach the effect identical with this embodiment.
Refer again to Fig. 3, containment member 540 comprises the through hole 541 that penetrates formation with second inlet 430 of second cyclone 400 accordingly.The through hole 541 of containment member 540 is adjusted each cross section of second inlet 430 of second cyclone 400 with the flow of the vortex of determining to enter second cyclone 400, and optimized vortex flow is set makes carry out centrifugal separation more reposefully in second cyclone 400.
With reference to Fig. 8, will the operation of above-mentioned multi cyclone dust-collecting apparatus 100 according to the embodiment of the invention be described.
The air that contains dirt rises to the top of first cyclone 300 by air intake duct 210, first inlet 360 and the tube connector 330 of dust collection shell 200.Be directed to air guide member 340 by tube connector 330 air discharged by separating guide 405.The air that is guided by air guide member 340 moves downward to first cyclone chamber 310, forms vortex and makes big relatively dirt particle be separated eccentrically, drop and be collected in first dust collection part 230 of dust collection shell 200.The air of isolating big dirt particle rises once more, and the grid body 371 of process grid members 370 is then by air outlet slit 350 dischargings.At this moment, the dirt particle that size is bigger than the size of the through hole of grid body 370 does not flow into grid body 371 and is filtered.
Air and air inlet/lid 511 collisions of giving vent to anger by air outlet slit 350 rises then disperse, and enter second cyclone chamber 410 by second inlet 430 of second cyclone 400 then through air guide passage 512 again.Air makes that owing to the structure of air guide passage 512 forms vortex tiny dirt particle is separated eccentrically.That is, isolate eccentrically not in first cyclone 300 by isolated tiny dirt particle eccentrically thereby air descend to form vortex, described tiny dirt particle falls and is collected in dust then and collects second dust of shell 200 and collect in the part 240.
After being separated tiny dirt particle, air is discharged then by each air discharging guide channel 513 to be assembled.The air of described gathering flows in the lid inlet 522 of whirlwind lid 521.Described air rises, with cover plate 524 collisions, disperse, descend and through filter member 530.The air that cleaning after process filter member 530 is crossed is discharged into the outside of multi cyclone dust-collecting apparatus 100 by lid outlet 523.Cover plate 523 is connected to the drive motors (not shown) that is used to provide driving force of vacuum cleaner directly or indirectly.
Though do not illustrate, for example various types of vacuum cleaners of upright vacuum cleaner or canister type vacuum cleaner optionally use above-mentioned Cyclonic dust-collecting appratus 100.
Fig. 9 and Figure 10 represent the view of cap unit 600 according to another embodiment of the present invention.More particularly, Fig. 9 is the decomposition diagram of cap unit 600, and Figure 10 is the perspective view that shows the Cyclonic dust-collecting appratus that is equipped with cap unit 600, and its part that has shown cover plate is more specifically to explain the operation of cap unit 600.
With reference to Fig. 9, this unit 600 comprises that air inlet/give vent to anger covers 610, whirlwind lid 620 and filter member 630.Because air inlet/give vent to anger cover 610 with embodiment formerly in air inlet/giving vent to anger to cover has identical structure and identical functions, so will omit detailed description.According to another embodiment of the present invention, described whirlwind lid 620 covers air inlet/give vent to anger and cover 610 and comprise whirlwind lid 621, lid inlet 622 and have lid and export 623 cover plate 624.
