As shown in fig. 3 to 6, in the present embodiment, the grille cover 51 is formed with an inner space, and one end thereof is a first opening 511 that is in fluid communication with the inner space, and the fan structure 52 is disposed at the first opening 511. Specifically, the fan structure 52 includes an outer wall 520 and an inner wall 521 which are substantially concentrically arranged, the outer wall 520 and the inner wall 521 are annular, the fan structure 52 further includes a plurality of blades 522 connecting the outer wall 520 and the inner wall 521, and one end of the grille cover 51 close to the first opening 511 is fixedly connected with the outer wall 520 of the fan structure 52. The air outlet 4 is further provided with a mounting frame 7, the mounting frame 7 comprises a plurality of support rods 71 extending from the casing 1 around the air outlet 4 into the air outlet 4, the plurality of support rods 71 are connected in the air outlet 4, and a rotating shaft 8 is arranged at the connection position. A mounting portion for mounting the filter structure 5 to the rotation shaft 8 is formed at an inner wall 521 of the fan structure 52 so that the filter structure 5 can rotate about the rotation shaft 8. In this embodiment, the fan structure 52 is configured to be driven to rotate by the airflow, but in other embodiments not shown in the figures, the fan structure 52 may also be configured to be driven to rotate by a motor.

With continued reference to fig. 3-6, the inner wall 521 has a mounting hole 6 formed therein, and the mounting hole 6 has a bearing 61 disposed therein; the shaft 8 is disposed in the mounting hole 6 and rotatably coupled to the fan structure 52 by a bearing 61. Specifically, one end of the mounting hole 6 near the first opening 511 is provided as a second opening 62, the bearing 61 can be pressed into the mounting hole 6 from the second opening 62, and the rotating shaft 8 can be inserted into the mounting hole 6 from the second opening 62 during mounting. The fan structure 52 and the joint with the rotating shaft 8 are arranged inside the grille cover 51, so that the winding and adhesion of dirt to the fan structure 52 and the bearing 61 can be reduced, and the bearing 61 (the joint of the filtering structure 5 and the rotating shaft 8) is not easy to block by dirt and cause blockage when the grille cover is used for a long time. In order to further prevent the filter structure 5 from being stuck, the bearing 61 may be disposed at an end of the mounting hole 6 far away from the second opening 62, and since the airflow is sucked by a vacuum cleaner fan (not shown in the figure) and flows toward the air outlet 4, the airflow is not easy to flow back into the mounting hole 6 from the second opening 62, and therefore, the bearing 61 is disposed at an end of the mounting hole 6 far away from the second opening 62, and dirt can be effectively prevented from entering the mounting hole 6 and attaching to the bearing 61 and a connecting portion between the bearing 61 and the rotating shaft 8, thereby playing a role of protection.

During filtering, the airflow enters the cyclone chamber 2 under the suction of the vacuum cleaner fan, after at least part of dirt is separated by the cyclone, the airflow passes through the rotating filtering structure 5 and then is discharged from the air outlet 4 to the outside of the cyclone chamber 2, and the discharged airflow is further filtered by the filtering piece 10 and finally discharged to the outside of the dust-air separation device.

Because the fan structure 52 and the joint of the filter structure 5 and the rotating shaft 8 are all positioned in the grille cover 51, dirty matters such as hair and the like are not easy to wind and adhere to the fan structure 52 and the joint of the filter structure 5 and the rotating shaft 8, and the filter structure 5 is not easy to block and block. In addition, since the second opening 62 of the mounting hole 6 is disposed at one end of the mounting hole 6 close to the air outlet 4, and the bearing 61 is disposed in the mounting hole 6 far from the second opening 62, the airflow and the dirt are not easy to flow back into the mounting hole 6, and are not easy to adhere to the bearing 61 and the connection position between the bearing and the rotating shaft 8.

After long-term use, the filtering structure 5 can be cleaned or replaced only by detaching the filtering structure 5 from the rotating shaft 8, and for convenience of cleaning, the grille cover 51 can be detachably connected with the outer wall 520 of the fan structure 52, specifically, as shown in fig. 6, the inner wall of the grille cover 51 is connected with the outer wall 520 of the fan structure 52 through threads, and of course, other detachable connecting structures can also be adopted.
