In this embodiment, the first positioning member 7 and the rotating shaft 9 may be provided in the above-described structure, and the first positioning member 7 abuts against the mounting tube 12 to prevent it from sliding along the rotating shaft 9.

In order to facilitate the assembly and disassembly of the filtering structure 5 and the cleaning thereof, the grille cover 51 may be detachably connected to the outer wall 520 of the fan structure 52, specifically, as shown in fig. 8, the grille cover 51 may be connected to the outer wall 520 of the fan structure 52 by a screw thread, and may be connected by a snap fastener or the like.

As shown in fig. 3, 4 and 6, taking the position of the rotating shaft 9 near the air outlet 23 as the first end 13, it is preferable to arrange the filter structure 5 connected to the first end 13 of the rotating shaft 9, i.e. the fan structure 52 in this embodiment is connected to the first end 13. This makes it possible to bring the connection of the filter construction 5 to the rotation shaft 9 closer to the housing 1 (mounting frame 10), i.e. the filter construction 5 is closer to the root of the rotation shaft 9. Because pivot 9 is during actual production, mostly plastic part and casing 1 integrated into one piece, or adopt metal material and casing 1 to mould plastics and be connected. Therefore, the stability of connection between the filter structure and the shell 1 is poor, and looseness or deformation can easily occur after long-term use, so that the filter structure 5 vibrates and even is blocked when rotating, and the filter effect and the use experience are influenced. Consequently, set up filter structure 5 and connect in the position department that the pivot 9 is close to air outlet 23, when filter structure 5 was rotatory like this, pivot 9's swing range is less for pivot 9 is connected with the casing more firm, thereby improves the rotatory stability of filter structure 5.

In addition, because the fan structure 52 is connected to the first end 13 of the rotating shaft 9, and the grille cover 51 is fixedly connected to the outer wall 520 of the fan structure 52, so that the top end of the whole filtering structure 5 is closer to the air outlet 23, in actual production, the top end of the filtering structure 5 (i.e. the top ends of the grille cover 51 and the fan structure 52) can be arranged to be in clearance fit with the casing 1 around the air outlet 23, so that a smaller distance is kept between the casing 1 and the casing 1, and therefore dirt is not easy to pass through a gap between the filtering structure 5 and the casing 1, and the filtering effect is improved. Adopt above-mentioned structure, because filtration 5 stability is better when rotatory, consequently even filtration 5 top and casing 1 with minimum interval clearance fit, it is difficult for taking place the dead condition of card. In order to further increase the stability of the filter structure 5, at least one bearing 61 may preferably be arranged in the through-opening 6 for connection to the rotational shaft 9.

The implementation principle of the embodiment is as follows: the airflow passes through the cyclone runway 22 to generate a rotating airflow in the cyclone chamber 2, and then part of the dirt is thrown into the dust collecting chamber 3 from the dust throwing port 31, so as to be separated from the airflow. When the airflow flows out of the air outlet 23, the airflow drives the fan structure 52 to rotate, so as to drive the grille cover 51 to rotate. So that the dirt in the subsequent airflow is not easy to pass through the grille cover 51 and cannot be discharged from the air outlet 23. The part of dirt blocked in the cyclone chamber 2 by the grille cover 51 is finally thrown into the dust collecting chamber 3 by the cyclone again, thereby further improving the separation efficiency.

Some dirt or hair strands, pet hair, etc. may pass through the grill cover 51 into the inner space thereof and adhere to or wind around the fan structure 52 or the rotary shaft 9. After long-term use, the hair hairs and other dirty materials on the fan structure 52 and the rotating shaft 9 are accumulated too much, so that blockage is caused or the fan structure 52 and the rotating shaft 9 are directly clamped, the filtering structure 5 is not rotated, and the filtering effect is seriously influenced. At this time, the user can detach the grille cover 51 from the fan structure 52, detach the first positioning member 7 from the rotary shaft 9, and finally pull out the fan structure 52 from the rotary shaft 9, so that the grille cover 51 and the fan structure 52 can be cleaned or replaced. When the fan structure is installed, the fan structure 52 is firstly sleeved on the rotating shaft 9, then the first positioning piece 7 is used for positioning the fan structure, and finally the grille cover 51 is fixed on the fan structure 52.

Furthermore, in order to improve the filtering effect, it is preferred that the filter structure is arranged in a direction perpendicular to the axis of the cyclone chamber 2, and the projection of the filter structure 5 towards the dust slinger opening 31 at least partially overlaps the area of the dust slinger opening 31, so that dirt can enter the dust collection chamber 3 quickly. A filter medium such as filter cotton 41 or hypa may also be provided at the butt joint 4, i.e., downstream of the air outlet 23 on the airflow path, to further adequately filter the dirt passing through the filter structure 5. Due to the cyclone separation and the filtration of the filtering structure 5, the filter cotton 41 and other media are not easy to block, so that compared with the traditional technology, the cleaning efficiency is high and the use experience is good.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
