  • 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.

  • Patent number: 11896192
    Abstract: A dirt detection method includes the steps of: selecting a motor with a motor processor, and then using the motor to provide power to form a negative pressure to suck the dirt into the dirt collection device, the motor processor sending the motor's operating signal to the detection processor that has written therein a threshold range for detection, and then comparing the threshold range with the operating signal from the motor processor. The invention is based on the motor as the power source of negative pressure, and the dirt collection device has good collection effect and sealing. Based on the equipment characteristics of the motor in the negative pressure system, the degree of dirt in the dirt collection device is detected by detecting the operating signal of the motor.

  • Patent number: 11896193
    Abstract: A method for influencing the device-typical sound emission of a cleaning device, wherein the cleaning device has a device housing and a cleaning mechanism for carrying out a cleaning activity on a surface to be cleaned, wherein the cleaning device emits device-typical sound while carrying out the cleaning activity, and wherein the device-typical sound is detected and analyzed with respect to at least one sound frequency contained therein. In order to adapt the soundscape of the cleaning device in such a way that a user can ascertain a proper functionality of the cleaning device, a displaceable section assigned to a flow channel of the cleaning device is displaced relative to the flow channel and/or the device housing in dependence on the analysis result until a characteristic sound frequency for the cleaning activity emitted by the cleaning mechanism has a defined amplitude.
