Dust collecting device and cleaning robot system

A dust collecting device, comprising:

• a bin;
• a dust bag assembly, detachably installed in the bin;
• a bin cover, capable of covering or opening the bin;
• a trigger structure;
• a detector;
• and
• a controller, all of the trigger structure, the detector and the controller arranged in the bin, the trigger structure capable of moving 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 pushing the trigger structure, such that the trigger structure moves from the initial position to the trigger position and triggers the detector;
• the controller electrically connected with the detector, the controller restricting an operation of the dust collecting device according to an untriggered state of the detector, and the controller releasing a restriction on the operation of the dust collecting device according to a triggered state of the detector.
