Abstract: A debris cleaning mechanism and a cleaning device, comprising a driving mechanism, a transmission mechanism, and a debris scraping mechanism. The transmission mechanism comprises a gear box, and the gear box is connected to the driving mechanism by means of an input shaft and connected to the debris scraping mechanism by means of an output shaft; the debris scraping mechanism comprises a debris scraping body, and the output shaft is in transmission connection with the debris scraping body to drive the debris scraping body to move; the debris scraping body is provided with a first and/or a second debris scraping strip. The cleaning device comprises a debris barrel, a debris barrel cover, the debris cleaning mechanism, and a cover opening mechanism; when a rack of the transmission mechanism moves to a preset position along the axial direction of the debris barrel, the cover opening mechanism is pushed to move.

Abstract: A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

Abstract: Embodiments of the present disclosure disclose a mounting bracket and a self-propelled robot. The mounting bracket includes a housing, a rotating shaft and a magnetic positioning assembly. The housing is provided with an inner cavity. The rotating shaft is configured to rotate about an axis in the inner cavity. The magnetic positioning assembly includes a first magnetic element and a second magnetic element which are respectively arranged on the housing and the rotating shaft. The laser distance sensor is attached to the rotating shaft and configured to rotate about the axis. The mounting bracket is configured to prevent the rotating shaft from deviating from the axis by generating a force between the first magnetic element and the second magnetic element in a radial direction of the rotating shaft.

Abstract: An autonomous cleaning device, includes: a mobile platform, configured to move autonomously on a cleaning surface; and a cleaning module, disposed on the mobile platform and including a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode.
