[0034] The adapter 2 is rotatably mounted on the floor brush 9. A ventilation duct 21 is provided in the adapter 2. The top of the adapter 2 is inserted into the connecting pipe 11.

[0035] The filter element 3 is arranged at the top opening of the barrel body 1 , and the vacuum cleaner main unit 4 is clamped on the top of the barrel body 1 , and the filter element 3 contacts the bottom surface of the vacuum cleaner main unit 4 .

[0036] The top opening of the barrel body 1 is provided with a stepped surface 14, and the filter element 3 is placed on the stepped surface 14. The filter element 3 only needs to be placed in the barrel body 1, and the vacuum cleaner main body 4 is clamped with the barrel body 1 so that the bottom surface of the vacuum cleaner main body 4 squeezes and positions the filter element 3, effectively simplifying the installation of the filter element 3, facilitating the removal and replacement of the filter element 3, and facilitating the emptying of dust.

[0037] The inner wall of the barrel body 1 is provided with a plurality of reinforcing ribs 15. The reinforcing ribs 15 are arranged along the height direction of the barrel body 1, effectively improving the anti-deformation ability of the barrel body 1.

[0038] Working Principle: The bottom of the special-shaped dust cup is rotatably mounted with the floor brush 9 via an adapter 2. The airflow carrying dust in the floor brush 9 enters the barrel 1 through the internal ventilation duct 21. After being filtered and separated by the filter element 3, the dust is discharged from the vacuum cleaner main unit 4 above the barrel 1. In an upright vacuum cleaner, the dust cup and the vacuum cleaner main unit 4 are arranged in sequence along the air flow direction. The shape of the dust cup is not restricted by the vacuum cleaner main unit 4. The dust cup can adopt a special-shaped structure according to the capacity and shape requirements, effectively ensuring the capacity of the dust cup, and the dust cup shape is flexible and changeable. The lower end surface of the bottom of the barrel 1 is arranged at an angle to prevent collision damage between the special-shaped dust cup and the floor brush 9 when the upright vacuum cleaner is rotated and laid down for use.
