  2. The cleaning system according to claim 1, wherein the locking mechanism comprises a locking body arranged on the dust cup, and a locking structure arranged on the cover door, wherein the locking body cooperates with the locking structure to selectively lock or unlock the cover door.
  3. The cleaning system according to claim 1, wherein the cover door comprises a rotating portion rotatably connected with the cup body, wherein during the withdrawal of the dust cup from the dust collection bin, the return member abuts against the rotating portion to allow the cover door to be rotated toward a direction close to the cup body, to drive the locking mechanism to perform locking.
  4. The cleaning system according to claim 3, wherein the return member abuts against a circumferential surface of the rotating portion in a state in which at least a part of the dust cup is located in the dust collection bin.
  5. The cleaning system according to claim 3, wherein a part of a circumferential wall surface of the dust collection bin protrudes inwardly to form the return member, and the return member is provided with an interference avoidance groove configured to avoid interference with the rotating portion, wherein a lower surface of the return member abuts against the rotating portion during the withdrawal of the dust cup from the dust collection bin.
  6. The cleaning system according to claim 2, wherein the locking body is slidably arranged on an outer wall of the cup body, and the unlocking member drives the locking body to slide, to allow the locking body to be separated from the locking structure.
  7. The cleaning system according to claim 6, wherein the locking mechanism comprises an elastic structure connected with the locking body, wherein the unlocking member drives the locking body to cause elastic deformation of the elastic structure, wherein during the withdrawal of the dust cup from the dust collection bin, the elastic structure recover the elastic deformation to allow the locking body to be returned.
  8. The cleaning system according to claim 6, wherein a part of a circumferential wall surface of the dust collection bin protrudes inwardly to form the unlocking member.
  9. The cleaning system according to claim 6, wherein an accommodating chamber for accommodating the locking body is formed on the dust cup, the accommodating chamber is provided with a communication opening toward the cover door, an extension opening communicating with the accommodating chamber is arranged on a periphery of the dust cup, a part of the locking body is arranged in the accommodating chamber, the locking body cooperates with the locking structure through the communication opening, and a part of the locking body passing through the extension opening is configured to be in contact with the unlocking member.
  10. The cleaning system according to claim 1, wherein an access opening communicating with the dust collection bin is formed on an upper surface of the dust collection bin, the dust discharge opening is formed on a lower surface of the cup body, the dust cup enters into and is withdrawn from the dust collection bin in a vertical direction through the access opening.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority to Chinese Patent Application No. 202321676943.7, filed on June 29, 2023, the contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD The present application relates to the technical field of cleaning devices, in particular to a cleaning system. BACKGROUND A vacuum cleaner comprises a dust cup. In order to clean dust in the dust cup, the vacuum cleaner is equipped with a base station. When in use, the vacuum cleaner is placed on the base station, and the dust in the dust cup is collected by the base station. In the related art, after the dust in the dust cup is collected by the base station, a user needs to manually close a cover door of the dust cup, which leads to a poor user experience. SUMMARY In view of this, embodiments of the present application are intended to provide a cleaning system that facilitates cleaning of dust in a dust cup. In order to achieve the above aim, the technical solutions of the embodiments of the present application are realized as follows. The embodiments of the present application disclose a cleaning system, comprising: a vacuum cleaner comprising a dust cup and a locking mechanism, in which the dust cup comprises a cup body and a cover door, the cup body is provided with a dust collection chamber and a dust discharge opening communicating with the dust collection chamber, the cover door selectively opens or closes the dust discharge opening, the locking mechanism is arranged on the dust cup and is configured to lock or unlock the cover door;an unlocking member; anda base station comprising a base body and a return member, in which the base body is provided with a dust collection bin. During entry of the dust cup into the dust collection bin, the unlocking member drives the locking mechanism to unlock the cover door, and during withdrawal of the dust cup from the dust collection bin, the return member drives the locking mechanism to lock the cover door. The embodiments of the present application disclose a cleaning system. When it is necessary to clean foreign matters in the dust collection chamber, the dust cup can be inserted into the dust collection bin, and then the unlocking member can drive the locking mechanism to unlock the cover door to allow the dust discharge opening to be opened. In this way, the dust in the dust collection chamber can enter into the dust collection bin through the dust discharge opening to allow the dust collection chamber to be cleaned, which provides a good dust storage space for the next cleaning of the surface to be cleaned. When the foreign matters in the dust collection chamber have been cleaned or it is necessary to clean the surface to be cleaned, the dust cup can be withdrawn from the dust collection bin. At this time, the return member drives the locking mechanism to lock the cover door, to allow the dust discharge opening to be automatically closed. In this way, the user can be prevented from getting his/her hands dirty due to a manually closing of the cover door, which provides a high degree of automation, and good user experience.
