Abstract

This invention provides a cleaning device, a cleaning control method, and an air purifier. The cleaning device includes: a cleaning component; a first sealing component disposed circumferentially along the object to be cleaned, used to seal the object circumferentially; and a second sealing component disposed at one end of the first sealing component. The first and second sealing components can form a closed cleaning cavity to accommodate the object to be cleaned. The cleaning component is located within the cleaning cavity and can clean the object inside the cleaning cavity. Based on the technical solution of this invention, a relatively sealed cavity capable of accommodating the object to be cleaned is constructed, which can effectively prevent the escape of harmful substances such as bacteria and particulate matter during the cleaning process, avoid contaminating the external environment, and prevent incomplete cleaning and disinfection.
