Fig. 7 is a schematic structural view of a filter frame according to an embodiment. Fig. 8 is a schematic structural view of the filter holder viewed from the second end toward the first end. Fig. 9 is a schematic structural diagram of a fan in an embodiment. Referring to fig. 1-3, there is disclosed in fig. 1 a vacuum cleaner 10 in which a dirt cup assembly 1 includes a cyclonic separation chamber 12 and a dirt collection chamber 13. The cyclone chamber 12 is provided outside the dust collecting chamber 13 and communicates with the dust collecting chamber 13 through an ash ejection port 14. Referring to FIG. 6, the dirt cup assembly 1 further includes an air outlet 123 and a filter structure 7 disposed at the air outlet 123, the filter structure 7 being rotatably disposed at the air outlet 123 to filter the airflow before exiting the air outlet 123. Referring to fig. 3 to 8, the filter structure 7 includes a filter net 74 and a guide rib 76 provided outside the filter net 74, the guide rib 76 protruding from an outer surface formed by the filter net 74. The inside is provided with rotatable filter screen 74, and the periphery of filter screen 74 is provided with the guide muscle 76 of the surface of protrusion filter screen 74, and rotatable filter screen 74 cooperates guide muscle 76, can effectively reduce the probability that hair twines filter screen 74.

With continued reference to fig. 3-6, 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 glued or otherwise secured to the filter frame 71 after being formed. 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 fig. 7 and 8, the filter frame 71 includes a fan mounting bracket 78 and a bearing mounting bracket 79, the fan mounting bracket 78 and the bearing mounting bracket 79 being connected 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 truncated cone-shaped or truncated pyramid-shaped receiving space. The filter frame 71 and the guide rib 76 may be integrally formed, and the filter net 74 is disposed inside the guide rib 76.

With continued reference to fig. 8-9, the outer diameter of the filter construction 7 decreases in a direction away from the air outlet opening 123. I.e. the hairs wound on the filter frame 71 are gradually thrown off during the rotation of the filter structure 7 and then into the dust-throwing port 14. That is, filter structure 7 includes a first end 711 near outlet port 123 and a second end 712 far from outlet port 123, and the first end 711 has an outer diameter larger 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 filtering structure 7 can be of a circular truncated cone shape or a prismatic truncated cone shape on the whole, and hair shedding is facilitated. 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 fig. 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 opening 123 and a second end 712 distal the air outlet opening 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. 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. 6, mounting bracket 75 includes a support member 751 secured to outlet port 123, with support member 751 being a cross-support structure, although in other implementations, support member 751 may be any support structure for rotatably mounting filter structure 7 to outlet port 123. The filter frame 71 is disposed in the accommodating groove 713, at least one bearing 753 is disposed in the accommodating groove 713, and the filter frame 71 is rotatably mounted to the mounting frame 75 by the at least one bearing 753. To facilitate the removal and installation of the filtering structure 7, the filtering structure 7 is mounted to one end of the fixed shaft 752 by means of a bearing 753, the other end of the fixed shaft 752 being fixed to the supporting structure, so that the fixed shaft 752 is stationary with respect to the supporting structure, which has the advantage that the possibility of entanglement of hairs entering the inside of the filtering structure 7 is reduced. Further, the fixing shaft 752 is detachably mounted to the supporting structure, so that the user can easily detach the fixing shaft to clean the filtering structure 7, even if there are impurities such as hairs remaining inside the filtering structure 7, the user can simply clean the impurities.

Referring to fig. 3-9, a fan 8 is disposed within the filter structure 7, and the fan 8 is rotated by the airflow exiting the air outlet 123, thereby rotating the filter structure 7. The fan 8 includes a proximal shaft end 84 proximate the axis of rotation P and a distal shaft end 83 distal from the axis of rotation P in the radial direction, the proximal shaft end 84 of the fan 8 being disposed in suspension relative to the mounting bracket 75. In one implementation, the fan 8 may be ring-shaped, and the center of the fan 8 is a hollow structure, which facilitates the passing of objects. The fan 8 comprises a plurality of fan blades 81, two ends of each fan blade 81 are fixed to corresponding circular rings, and a space defined by the inner circular ring (namely the shaft end close to the fan) can ensure that objects can freely pass through the space. Further, the fan 8 includes a plurality of blades 81, and the proximal ends 84 of the plurality of blades 81 are all suspended. In one embodiment, fan blades 81 may be molded directly to filter frame 71. In another implementation, the fan 8 may be a separately manufactured part, and the fan 8 may be fixed to the inside or outside of the filter frame 71 by clamping, gluing, or ultrasonic welding after the manufacturing is completed. Flabellum 81 adopts unsettled mode, can increase the circulation of air area on the one hand, and on the other hand, can effectively avoid the hair to twine on flabellum 81.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application suitable for this invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and illustrations shown and described herein, without departing from the general concept defined by the claims and their equivalents.
