2 . The dust collector according to claim 1 , wherein the air inlet ( 201 ) is connected with the dust-laden air inlet ( 101 ) via a dust-laden air tube ( 40 ).

3 . The dust collector according to claim 2 , wherein the air inlet ( 201 ) is formed in a side wall of the cyclone barrel ( 20 ) and the dust-laden air inlet ( 101 ) is formed in a side wall of the dust-collection container ( 10 ).

4 . The dust collector according to claim 2 , wherein a plurality of first air holes ( 401 ) is formed in a wall of the dust-laden air tube ( 40 ).

5 . The dust collector according to claim 1 , wherein a distance between the lower surface ( 311 ) of the flange ( 31 ) and the upper end ( 202 ) of the cyclone barrel ( 20 ) ranges from 10 mm to 35 mm.

6 . The dust collector according to claim 1 , wherein the dust-collection container ( 10 ) comprises a body ( 11 ) having an open upper end and a cover ( 12 ) detachably coupled to the body to close the upper end of the body ( 11 ), and the air outlet ( 102 ) is formed in the cover ( 12 ).

7 . The dust collector according to claim 6 , wherein the flange ( 31 ) is mounted on an inner wall of the body ( 11 ) and adjacent to the upper end of the body ( 11 ).

8 . The dust collector according to claim 7 , wherein an annular groove ( 312 ) is formed in an outer periphery surface of the flange ( 31 ), and a plurality of notches ( 3121 ) is formed in an upper wall of the annular groove ( 312 ) and spaced from one another in a circumferential direction of the flange ( 31 ),
wherein a plurality of positioning bosses ( 111 ) is disposed on the inner wall of the body ( 11 ), adjacent to the upper end of the body ( 11 ), and adapted to fit within the annular groove ( 312 ) via the plurality of notches ( 3121 ) respectively.

9 . The dust collector according to claim 6 , wherein a plurality of second air holes ( 105 ) is formed in at least one of a side wall and a bottom wall of the body ( 11 ).

10 . The dust collector according to claim 6 , wherein the cyclone barrel ( 20 ) is mounted onto the body ( 11 ) via screws.

11 . The dust collector according to claim 6 , wherein the cyclone barrel ( 20 ) and the body ( 11 ) are formed integrally.

12 . The dust collector according to claim 1 , wherein a rib ( 13 ) is disposed on at least one of a side wall and a bottom wall of the second chamber ( 104 ).

13 . The dust collector according to claim 12 , wherein a plurality of ribs ( 13 ) is arranged in a circumferential direction of the dust-collection container ( 10 ).

14 . The dust collector according to claim 1 , wherein a filtering air outlet ( 33 ) is formed at a joint of the upper end of the filtering cup ( 32 ) and the lower surface ( 311 ) of the flange ( 31 ) and communicates with the air outlet ( 102 ) of the dust-collection container ( 10 ).

15 . A cleaner, comprising the dust collector for a cleaner according to claim 1 .

16 . The cleaner according to claim 15 , wherein the air inlet ( 201 ) is connected with the dust-laden air inlet ( 101 ) via a dust-laden air tube ( 40 ).
