Referring to FIG. 1, FIG. 1 discloses a surface cleaning apparatus 10 comprising a dirt cup assembly 1 and a fan assembly 3, the fan assembly 3 for generating a suction airflow and the dirt cup assembly 1 for separating dirt from an airflow carrying the dirt. Referring to fig. 2-9, the dirt cup assembly 1 includes a cyclone chamber 12 and a dirt collection chamber 13, the cyclone chamber 12 being disposed outside of the dirt collection chamber 13 and communicating with the dirt collection chamber 13 through an ash slinger 14. The dirty air flow enters from the air inlet of the cyclone separation chamber 12 and then is subjected to cyclone separation in the cyclone cavity, the separated dust, impurities and the like enter the dust collection chamber 13 through the dust throwing port 14, and the separated air flow flows out of the cyclone separation chamber 12 through the air outlet 123 of the dust cup assembly 1. 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 mounting bracket 75 within the dirt cup assembly 1 to filter the air flow before exiting the air outlet 123.

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 comprises a proximal shaft end 84 close to the rotation axis P and a distal shaft end 83 remote from the rotation axis P in the radial direction, the proximal shaft end 84 of the fan 8 being arranged in suspension. In one implementation, the fan 8 may be ring-shaped, and the center of the fan 8 is a hollow structure, defining a channel for passing objects. The fan 8 comprises a plurality of blades 81, both ends of the blades 81 are fixed on corresponding circular rings, and a channel defined by an inner circular ring (namely, the end close to the shaft of the fan) can ensure that objects can freely pass through the channel. 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 can be a separately manufactured part, and the fan 8 can be fixed to the inside or outside of the filter frame 71 by clamping, gluing, or ultrasonic welding after the manufacturing. 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.

With continued reference 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 air outlet 123, and it is understood that mounting bracket 75 may be disposed in air outlet 123, or disposed at a position near upstream and downstream of air outlet 123, and the specific position is not limited in detail here. With at least part of the mounting bracket 75 extending through the passage and with the proximal end 84 of the fan 8 disposed in suspension relative to the mounting bracket 75. Referring to the figures, mounting bracket 75 includes a support 751 secured to outlet port 123, support 751 being a cross-support structure, although in other implementations, support 751 may be any support structure for rotatably mounting filter structure 7 to outlet port 123. To facilitate the removal and installation of the filtering structure 7, the filtering structure 7 is mounted, by means of a bearing 753, to one end of a fixed shaft 752, 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, the fixed shaft 752 penetrating the passage defined by the proximal end 84 of the fan 8. The advantage of the stationary shaft 752 in relation to the support structure is that the chance of entanglement of hairs entering the interior of the filter 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 the drawings, the filter frame 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 713.

Of course, the filter screen 74 may also be integrally formed with the filter frame 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 the filter screen 74 and guide the hairs to move downwards so that the hairs are detached from the filter structure 7. Referring to fig. 7-8, the filter carrier 71 includes a fan mounting bracket and a bearing mounting bracket coupled to each other by a plurality of guide ribs 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 frame 71 are gradually thrown off during the rotation of the filter structure 7 and then into the dust-throwing port 14. Referring to fig. 7 and 8, filter structure 7 includes a first end 711 near air outlet 123 and a second end 712 far from air outlet 123, and an outer periphery of first end 711 is provided with guard plate 77 extending outward in the radial direction. The guard plate 77 extends outwardly in the radial direction over a distance effective to prevent hair from entering the interior of the filter construction 7.
