Gap between second level whirlwind cone 7 and second level dust barrel 8.Air after secondary cyclone separates is then through cyclone channel entrance
It is drawn upwardly out after in 711 entrance secondary filtration chambers 201.
In order to enable the air being discharged into atmosphere has better cleanliness, avoids doing harm to huamn body, be revolved by second level
The air of wind separator discharge can further progress filtering.In the present embodiment, the center of top of dirt cup top cover 6 is provided with top cover
Outlet, the top opening of whirlwind bucket 71 correspond to top cover outlet, and the filtering dress corresponding to top cover outlet is provided in dirt cup top cover 6
9 are set, filter device 9 includes the filter holder 91 being set in dirt cup top cover 6, and filter holder 91 is provided with filtration members, filtration members
For Hai Pa or filtering sponge, it is extracted after filter device 9 by the air of top cover outlet.In filter holder 91 and dirt cup top cover
4th sealing ring 93 is set between 6, and then guarantees that the air straight line Jing Guo filtration members is discharged upwards, improves discharge efficiency.
After first level filtering device and secondary cyclone filtering dust, need periodically to open dirt cup bottom cover 5 for level-one
The dust stored up in grey chamber 102 and the grey chamber 202 of second level storage is outwelled, and 5 opening and closing type of dirt cup bottom cover of the utility model is connected to cup
The bottom of body 1.Specifically, one end of dirt cup bottom cover 5 and cup body 1 are hinged, and the other end and cup body 1 fasten.This mode is being opened
It when dirt cup bottom cover 5, disposably opens level-one and stores up grey chamber 102 and the grey chamber 202 of second level storage, so that the disposable cleaning of realization, operates
It is convenient.
Based on above structure, the dust catcher second level cyclonic filter dirt cup of the utility model at work, air flowing
Direction is as shown in Figure 4:
1) dust and gas is entered in air intake passage 100 by cup body air inlet 11；
2) entered in by-pass filtration chamber 101 by air intake passage 100, the level-one dust after by-pass filtration falls into level-one and stores up grey chamber
In 102, the dust and gas after by-pass filtration enters cyclone channel 200 by filter screen 3, completes by-pass filtration；
3) dust and gas in cyclone channel 200 flows to whirlwind cover entrance 74, and drawing in whirlwind helicoid 73 from the bottom to top
It leads lower downward dive to screw in the gap between whirlwind bucket 71 and second level dust barrel 8, second level dust is fallen under the influence of centrifugal force
Second level is stored up in grey chamber 202, and air then passes through cyclone channel entrance 711 and enters in secondary filtration chamber 201；
4) air in secondary filtration chamber 201 is further filtered by the top cover outlet of dirt cup top cover by filter device 9
After be drawn upwardly out.
In entire filter process, air enters from the upper lateral part of cup body 1, realizes filtering from top to bottom inside cup body 1,
Air after final filtration, which is pumped down to from the bottom to top from the top of cup body 1, to flow out, and changes following side air inlet in the prior art, on
The mode of side outlet or top outlet effectively improves filter efficiency, and by configured in this way, dust and gas separated structure being effectively reduced
Occupied dirt cup space realizes the grey volume of maximum storage, improves collection efficiency.
