Description

[0001] This application is a divisional application of the Chinese patent application with the application date of January 2, 2020, application number "202010002112.6", and invention name "A charging device, a vacuum cleaner and a cleaning system". Technical Field

[0002] The present application relates to the technical field of cleaning tools, and in particular to a charging device, a vacuum cleaner and a cleaning system. Background Art
