  • Patent number: 11910988
    Abstract: A dust collecting device includes a bin, a dust bag assembly, a bin cover, a trigger structure, a detector and a controller. The trigger structure moves between an initial position in which the trigger structure does not trigger the detector and a trigger position in which the trigger structure triggers the detector. When the dust bag assembly is installed in the bin and the bin cover covers the bin, the dust bag assembly and the bin cover respectively pushes the trigger structure, such that the trigger structure moves from the initial position to the trigger position and triggers the detector. The controller is electrically connected with the detector. The controller restricts an operation of the dust collecting device according to an untriggered state of the detector, and releases the operation of the dust collecting device according to a triggered state of the detector.
