As in Fig. Figures 1 to 4 show that the dust cup 140 is used in a vacuum cleaner 100 and has a base surface A1. The dust cup 140 comprises an inner cavity 141 and a dust extraction opening 142. The inner cavity 141 is used to hold dust, and the dust extraction opening 142 connects the inner cavity 141 to an outer surface of the dust cup 140 at the base surface A1. The dust in the inner cavity 141 can be extracted through the dust extraction opening 142, with an open end face of the dust extraction opening 142 intersecting the base surface A1. In this embodiment, a dust extraction opening 142 is provided to discharge the dust contained in the dust cup 140. When the dust needs to be discharged, the dust extraction opening 142 can be opened, and this special opening is used exclusively to improve the efficiency of dust removal.Furthermore, the overlap of the open end surface and the bottom surface A1 of the dust extraction opening 142 can ensure that the gas forms a rotating airflow when the dust is discharged from the dust extraction opening 142, and the dust is discharged together to improve the efficiency of the discharge of the dust from the dust cup 140.

[0046] In some optional embodiments, the open end face of the dust extraction opening 142 is positioned perpendicular to the floor surface A1, so that the airflow direction at the dust extraction opening 142 is parallel to the tangential direction of the floor surface A1 at the dust extraction opening 142. This embodiment is a preferred embodiment, and the efficiency of dust removal from the dust cup 140 can be further improved by adjusting the angle between the open end face of the dust extraction opening 142 and the floor surface A1.

[0047] In some optional embodiments, the number of dust extraction openings 142 is two or more, wherein the two or more dust extraction openings 142 are arranged in a rotationally symmetrical row centered on a midpoint of the base surface A1. Optionally, the number of dust extraction openings 142 can be adapted according to the size of the respective dust cup 140, the application scenario, and so on. Two or more dust extraction openings 142 are arranged in a rotationally symmetrical row with the midpoint of the base surface A1, and this rotationally symmetrical arrangement of the dust extraction openings 142 with the midpoint of the base surface A1 can promote the formation of the rotating airflow.

[0048] In some optional embodiments, the dust extraction openings 142 are provided adjacent to an outer edge of the base surface. Optionally, the dust cup 140 is cylindrical, and the dust extraction opening 142 is located on the base surface A1 of the cylindrical dust cup 140, which increases the dust collection area.

[0049] In some optional embodiments, the dust cup 140 may further comprise a dust extraction groove 143.

In the above embodiments, the dust extraction opening 142 may be located in the inner cavity 141 of the dust cup 140 or on the outside. Without specific limitation, this embodiment is a preferred embodiment: the dust extraction opening 142 is provided on the side wall of the dust extraction groove 143, the dust extraction groove 143 is provided on the base surface A1, and the dust extraction opening 142 is located inside the dust cup 140. This improves the aesthetics of the structure and effectively prevents damage to the dust extraction opening 142 from external mechanical impact.At least a part of the groove bottom of the vacuuming groove 143 is inclined relative to the floor surface A1, so that the angle of the open end surface of the vacuuming opening 142 can be adjusted by the inclination angle of the groove bottom and the dust-laden airflow flows out of the vacuuming opening 142 and the groove bottom of the vacuuming groove 143.

[0050] In some optional embodiments, the groove base is inclined at an angle of 45 degrees or less relative to the base surface A1. This angle setting can cause the opening direction of the dust extraction opening 142 to be tangential with respect to the base surface A1, and as the airflow passes through the dust extraction opening 142, the airflow has a tangential velocity, thus creating a rotating airflow and increasing the discharge efficiency of the dust collection.

[0051] In some optional embodiments, one end of the groove base facing away from the dust extraction opening 142 abuts the base surface A1 and has a rounded transition. This embodiment prevents the accumulation of dust and facilitates dust discharge.

[0054] In some optional embodiments, the hinged lid 144 is connected to the dust extraction opening 142 by means of an elastic element, which is used to return the hinged lid 144 to the closed position. The elastic element can be a torsion spring. When dust is collected from the outside of the dust cup 140, the hinged lid 144 is sealed under the negative pressure created by the elastic element and the torsion spring. When dust is collected in the inner cavity of the dust cup 140, a negative pressure is created on the outside of the dust cup 140, and the outside overcomes the elastic force of the torsion spring, opening the hinged lid 144.
