Abstract

The application belongs to the technical field of cleaning robot equipment, and particularly relates to a filtering dust collecting device and a cleaning robot. The filter dust collector comprises a shell, an inner shell component, a first filter structure, a second filter structure and a third filter structure. In this filter dust collector, the air current that carries debris rubbish and dust is filtered, separated layer by layer through second filtration, first filtration and third filtration in proper order for the debris rubbish and dust that are inhaled along with the air current is more thoroughly trapped in filter dust collector, and the mode of layering filtration separation debris rubbish and dust is difficult to cause the filtration jam. Therefore, the problem that the HEPA filter screen is easily blocked by dust or clastic rubbish in the existing cleaning robot, so that the suction force of the cleaning robot is weakened, and the dust collection cleaning effect is affected when the cleaning work is carried out can be solved by using the technical scheme.
