Description

CROSS-REFERENCE TO RELATED APPLICATION This application is based on and claims priority to Chinese patent application No. 202321813201.4, filed on July 11, 2023. The entire contents of the above-mentioned Chinese patent application are incorporated herein by reference. TECHNICAL FIELD The present application relates to the technical field of cleaning device, in particular to a cleaning system. BACKGROUND A vacuum cleaner comprises a dust cup and a covering door. In order to clear foreign objects in the dust cup, the vacuum cleaner is equipped with a base station. When in use, the vacuum cleaner is inserted into the base station to clear the foreign objects in the dust cup. In the related art, after the vacuum cleaner is inserted into the base station, the covering door will automatically open, so that the foreign objects in the dust cup will automatically fall into the base station, and the user's controllability of the vacuum cleaner is decreased. SUMMARY In view of this, embodiments of the present application provide a cleaning system capable of improving user control of a vacuum cleaner. In order to achieve the above purpose, the technical solutions of the embodiments of the present application can be achieved as follows: An embodiment of the present application discloses a cleaning system comprising: a base station, a vacuum cleaner, a primary lock and an unlocking mechanism. A dust collection bin is formed in the base station. The vacuum cleaner comprises a dust cup assembly, the dust cup assembly comprising a dust cup and a covering door. The dust cup is formed with a dust collection chamber and a dust discharge opening communicated with the dust collection chamber, and the covering door is configured to selectively open or close the dust discharge opening. The primary lock is disposed at a junction of the dust cup and the covering door, and is configured to selectively lock or unlock the covering door. The unlocking mechanism comprises a primary unlocking member and a secondary lock. The secondary lock is disposed at the base station. In a state where the vacuum cleaner is docked with the base station, the primary unlocking member allows the primary lock to unlock the covering door, and the secondary lock selectively locks or unlocks the covering door. The embodiment of the present application discloses the cleaning system. By forming the dust collection chamber and the dust discharge opening in the dust cup, the covering door can selectively open or close the dust discharge opening, and the primary lock can selectively lock or unlock the covering door. In this way, when the vacuum cleaner operates on a surface to be cleaned, the primary lock can lock the covering door to close the dust discharge opening. In this way, foreign objects such as dust or garbage in the dust collection chamber can be prevented from leaking out of the dust cup through the dust discharge opening. By forming the dust collection bin in the base station, when it is necessary to clear foreign objects in the dust collection chamber, the vacuum cleaner can be inserted into the base station, and the primary unlocking member can enable the primary lock to unlock the covering door, and the primary lock is in an unlocked state. In this way, when the user does not want to clean the dust collection chamber or forgets to load the dust bag, the covering door can be locked by the secondary lock, so as to avoid accidental opening of the covering door. When the dust collection chamber needs to be cleaned, the covering door can be unlocked by operating the secondary lock to open the dust discharge opening. In this way, the opening of the covering door can meet the subjective will of the user, and the user's control of the vacuum cleaner can be improved. After the primary unlocking member enables the primary lock to unlock the covering door and the secondary lock unlocks the covering door, the foreign objects in the dust collection chamber can be collected in the dust collection bin through the dust discharge opening, so that the cleanliness in the dust collection chamber can be maintained, thereby providing a good foreign objects and dust storage space for the next cleaning of the surface to be cleaned.
