This allows the inner race of the bearing 61 to be fixedly connected to the shaft 9 so that the filter structure 5 is mounted to the shaft 9 and is able to rotate about the shaft 9. The diameter of the inner ring of the bearing 61 is set to be larger than or just equal to the outer diameter of the rotating shaft 9, so that the bearing 61 can slide on the rotating shaft 9 conveniently; the second positioning element 71 can be a convex ring positioned on the side wall of the rotating shaft 9, and the first positioning element 7 is detachably connected to the rotating shaft 9, so that when the bearing 61 is installed, the bearing 61 can be sleeved on the rotating shaft 9 from one end of the rotating shaft 9 and slides towards the direction of the second positioning element 71, and finally the second positioning element 71 is abutted to the inner ring of the bearing 61; at this time, the first positioning member 7 is connected to the rotating shaft 9, and the inner ring of the bearing 61 at the other end is abutted against the first positioning member 7, so that the installation is completed.

After long-term use, when winding on pivot 9 and fan structure 52 when dirty or when breaking down such as hair, the user can pull down first locating piece 7 from pivot 9, then is close to the one end roll-off of first locating piece 7 with filtration 5 from pivot 9, can realize dismantling filtration 5's effect to be convenient for clear up or change filtration 5. It should be noted that, the inner ring of the bearing 61 is configured to slide along the rotating shaft 9, and besides the two ways of setting the diameter of the inner ring of the bearing 61 to be greater than or equal to the outer diameter of the rotating shaft 9, the diameter of the inner ring of the bearing 61 may also be set to be slightly smaller than the outer diameter of the rotating shaft 9, at this time, the inner ring of the bearing 61 is in interference fit with the rotating shaft 9, but it still has the ability of allowing a user to slide the bearing 61 off the rotating shaft 9, and at this time, the inner ring of the bearing 61 should also be regarded as being slidably connected with the rotating shaft 9. In this embodiment, a threaded section 91 is arranged at one end of the rotating shaft 9 far away from the air outlet 23, the first positioning piece 7 is arranged to be of a nut type structure with an internal thread, and the first positioning piece 7 and the rotating shaft 9 can be connected in other detachable connection modes.

As shown in fig. 5, in another embodiment, a bearing 61 is disposed in the through hole 6, the bearing 61 is fixedly disposed in the through hole 6, the bearing 61 includes a bearing inner ring, a mounting tube 12 is interference-connected in the bearing inner ring, and the mounting tube 12 and the rotating shaft 9 can be configured to be in a key connection manner such that the mounting tube 12 can slide along the axial direction of the rotating shaft 9. 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 pipe 12 so as to be prevented 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 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 the metal material to mould plastics with casing 1 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 connection filter structure 5 in the position department that the pivot 9 is close to air outlet 23, like this when filter structure 5 is rotatory, 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 rotary 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 collection chamber 3 from the dust throwing port 31, so that the dirt is separated from the airflow. When the airflow flows out from 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 can not be discharged from the air outlet 23. The part of the 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 get entangled with 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 grille cover is installed, the fan structure 52 is sleeved on the rotating shaft 9, then the first positioning piece 7 is used for positioning the rotating shaft, 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 filtering 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 some embodiments of the present invention, and the description thereof is 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. Therefore, the protection scope of the present invention should be subject to the appended claims.
