Cleaning Device and Dust Collecting Method

Abstract

A cleaning device includes a dust suck assembly, a dust suck assembly and a first suck power source. The dust suck assembly includes a dust cup which includes a cup body and a cover movably connected to the cup body. The cup body and the cover constitute a first dust collecting chamber. The dust collecting assembly includes a second dust collecting chamber. The first suck power source is arranged in the dust suck assembly or the dust collecting assembly, and is configured to generate negative pressure in the second dust collecting chamber. The cover is configured to open relative to the cup body under the triggering of the negative pressure, to interconnect the first dust collecting chamber and the second dust collecting chamber. The dust cup interconnects with the second dust collecting chamber during dust collection.
