Fig. 9 is a schematic structural diagram of a fan in an embodiment. Referring to fig. 1-9, a vacuum cleaner 10 is disclosed, the dirt cup assembly 1 of the vacuum cleaner 10 including a cyclonic separation chamber 12 and a dirt collection chamber 13. The dirt cup assembly 1 also includes an air outlet 123 for discharging the separated airflow from the cyclonic separating chamber 12. A filter structure 7 is disposed at the air outlet 123 to filter the air flow before exiting the air outlet 123, and the filter structure 7 is rotatably disposed at the air outlet 123. The dirt cup assembly 1 is further provided with a mounting bracket 75 disposed at the air outlet 123 for supporting the filter structure 7. Mounting bracket 75 is disposed at outlet port 123, and it should be understood that mounting bracket 75 may be disposed in outlet port 123, or may be disposed at a position near upstream and downstream of outlet port 123, and the specific position is not limited in detail here. Referring to fig. 4 and 6, filter structure 7 includes a first end 711 proximate to outlet 123 and a second end 712 distal to outlet 123, second end 712 being rotatably mounted to mounting bracket 75 such that filter structure 7 is rotatable with respect to mounting bracket 75. Because the rotating structure is easily affected by dust, hair, etc., the second end 712 can be rotatably mounted on the mounting bracket 75, so that the dust, hair, etc. can be effectively prevented from being accumulated at the second end 712, and the service performance and the service life of the filtering structure 7 can be improved. Since the airflow is directed towards the air outlet 123, i.e. away from the second end 712, the dust and hair are brought to a position away from the second end 712, thereby effectively protecting the rotating structure.

With continued reference to fig. 3-9, the filter structure 7 includes a filter frame 71 and a filter screen 74 disposed on the filter frame 71, wherein the filter screen 74 may be a metal mesh, and the metal mesh may be formed and then glued or otherwise secured to the filter frame 71. Of course, the filter net 74 may be formed integrally with the filter holder 71. The filter structure 7 further comprises at least one guiding rib 76 arranged outside the filter screen 74, the guiding rib 76 protrudes out of the outer surface formed by the filter screen 74, and the guiding rib 76 extends along the circumferential direction and the length direction of the filter structure 7. The guide ribs 76 prevent hairs or the like from abutting against the filter sieve 74 and guide the hairs to move downwards so that the hairs are detached from the filter structure 7. Referring to the drawings, the filter stand 71 includes a fan mounting bracket 78 and a bearing mounting bracket 79, and the fan mounting bracket 78 and the bearing mounting bracket 79 are connected to each other by a plurality of guide ribs 76. The number of the guide ribs 76 is 3 or more. Not only can make the structure more firm, still be favorable to the hair to drop. The plurality of guide ribs 76 define a circular truncated cone-shaped or truncated pyramid-shaped accommodating space. The filter holder 71 and the guide rib 76 may be integrally formed, and the filter net 74 is disposed inside the guide rib 76. The outer diameter of the filter structure 7 gradually decreases in a direction away from the air outlet port 123. I.e. the hairs wound on the filter holder 71 are gradually thrown off during the rotation of the filter construction 7 and then into the dust-throwing opening 14. That is, filter structure 7 includes a first end 711 near outlet port 123 and a second end 712 remote from outlet port 123, with first end 711 having an outer diameter greater than that of second end 712. The second end 712 is suspended in the cyclone chamber 12, and the outer diameter of the filter structure 7 gradually decreases in a direction away from the air outlet 123. I.e., the outer diameter of the fan mounting bracket 78 is greater than the outer diameter of the bearing mounting bracket 79. So that the filter structure 7 hangs like a truncated cone structure within the cyclonic separating chamber 12 to facilitate the shedding of hairs from the second end 712. The first end 711 of the filter structure 7 is suspended relative to the mounting bracket 75. The filtering structure 7 can be of a circular truncated cone shape or a truncated pyramid shape on the whole, so that the hair can fall off conveniently. To further enhance the chance of hair falling, the guide ribs 76 extend both in the circumferential direction and in the length direction of the filter structure 7.

Referring to figures 3-6, the dirt cup assembly 1 further includes a mounting bracket 75 for supporting the filter structure 7, the filter structure 7 including a first end 711 proximate the air outlet 123 and a second end 712 distal the air outlet 123, the second end 712 being rotatably mounted to the mounting bracket 75 such that the filter structure 7 is rotatable relative to the mounting bracket 75.
