[0022] Reference Figures 1 to 3 This utility model provides a dust cup, including a cyclone assembly 2 and a filter assembly 1. The filter assembly 1 includes a filter screen support and a filter screen 10. The cyclone assembly 2 is partially disposed in the filter screen 10 support and is rotatably connected to the filter screen 10 support. The filter screen 10 is assembled on the filter screen 10 support and rotates synchronously with the filter screen 10 support.

[0023] The filter screen 10 of the dust cup of this utility model can rotate synchronously with the filter screen support, so that the dirt sucked into the dust cup is less likely to clog the mesh of the filter screen 10, reducing the risk of the mesh of the filter screen 10 being clogged and improving the problem of reduced suction power of the vacuum cleaner caused by the mesh of the filter screen 10 being clogged.

[0024] In some embodiments, a plurality of baffles 13 are provided on the outer side of the filter support 10, and the baffles 13 are evenly distributed along the circumference of the filter support. The dust cup of this invention has a plurality of baffles 13 arranged circumferentially on the outer side of the filter support. When the airflow generated by the suction motor acts on the baffles 13, the baffles 13 can drive the filter to rotate, thus eliminating the need for a motor to drive the filter support and reducing the cost of the vacuum cleaner.

[0025] In some embodiments, the baffle 13 is inclined.

[0026] In a preferred embodiment, the angle between the centerline of the baffle 13 along its length and the axis of the mounting surface 120 is an acute angle, thereby facilitating the airflow energy generated by the motor to act on the baffle 13 to drive the filter assembly 1 to rotate.

[0027] As another preferred embodiment, the filter support has an annular mounting surface 120, and the baffle 13 is inclinedly disposed on the mounting surface 120, so that the airflow energy generated by the motor can act on the baffle 13 to drive the filter assembly 1 to rotate.

[0028] In some embodiments, the baffle 13 is a thin, acute-angled trapezoidal sheet. The long side of the sheet is connected to the filter screen 10 support, and the connection between the short side and the two side sides is rounded, meaning the connection between the short side and the two side sides is smooth. Under the same suction force, this structure of the baffle 13 allows the airflow generated by the motor to act more effectively on the baffle 13, thereby driving the filter screen support to rotate.

[0029] In some embodiments, the filter screen 10 support includes a first support 11 and a second support 12, with the filter screen 10 disposed between the first support 11 and the second support 12, and the upper end and lower end of the filter screen 10 connected to the first support 11 and the second support 12, respectively.

[0030] In some embodiments, the second bracket 12 has the aforementioned annular mounting surface 120, and a plurality of baffles 13 are evenly distributed along the circumference of the mounting surface 120.

[0031] In some embodiments, the upper end of the cyclone assembly 2 is nested in the top of the first bracket 11, and the lower end of the cyclone assembly 2 is configured in the second bracket 12 via a bearing.

[0032] Furthermore, a limiting structure is constructed between the upper end of the cyclone assembly 2 and the top end of the first support 11 to ensure that the filter assembly 1 can rotate stably.

[0033] Specifically, the limiting structure includes a limiting platform 110 disposed on the outer side of the top of the first support 11 and a limiting protrusion ring 20 disposed on the upper end of the cyclone assembly 2. The side wall of the limiting platform 110 is inserted into the limiting protrusion ring 20 and the bottom wall of the limiting platform 110 abuts against the lower surface of the limiting protrusion ring 20.

[0034] This utility model also provides a vacuum cleaner, including the dust cup described above.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
