Abstract: Disclosed is a linkage limiting assembly applied in a vacuum cleaner, which is mounted within a frame of the vacuum cleaner. The linkage limiting assembly includes a triggering button arranged at the rear end of the frame, a pushing member configured to push an electric fan assembly or a dust barrel of the vacuum cleaner upwards, a limiting member configured to limit the maximum stroke of the electric fan assembly or the dust barrel, and a linking member connecting the triggering button with the limiting member in a force transmission manner.

Abstract: A handheld vacuum cleaner includes a frame, and a dust barrel and a locking portion mounted on the frame, wherein a front end of the dust barrel and the locking portion are movable relative to each other and are arranged opposite to each other; the dust barrel has a rotatable front cover at a front side thereof; and when the locking portion and the dust barrel move with respect to each other, the front cover is automatically rotatable to open, or close on the front side of the dust barrel due to limit by the locking portion.

Abstract: The present disclosure discloses a floor cleaning apparatus, comprises a cleaning robot and a washing base, and the cleaning robot comprises a robot main body and a mop assembly; the mop assembly is provided with a turntable-type mop mechanism able to stretch out downwards; the washing base comprises an outer container, a rinse tank and a solution-feeding mechanism. In the technical scheme disclosed, the automatic floor cleaning and finishing cloth washing are achieved so as to realize intelligent automatic cleaning, effectively removing dirt attached to the finishing cloth automatically, and freeing from artificially detaching and then washing the finishing cloth stained with dirt, automatically performing washing operation, and greatly alleviating operation burden of a user. Meanwhile, with the structure of the finishing cloth with a lifting structure, secondary pollution caused by the finishing cloth is avoided.

Abstract: The technical scheme adopted by the present disclosure discloses an outer rotor brushless motor, which has a motor housing, a magnet, an end cover and a retainer ring, and a plurality of mounting separators all integrally molded with the motor housing are evenly distributed on the inner wall of the motor housing; between two adjacent mounting separators, a mounting groove is provided for a magnet to be mounted; the magnet is mounted within the mounting groove and is axially limited by means of the end cover and the retainer ring. The outer rotor brushless motor disclosed offers good reliability and high efficiency in assembly.

Abstract: A roller brush assembly comprises a roller and a brush set on the roller. The roller contains an interior cavity constituted by at least two barrel bodies. Each portion of the barrel body edge is serrated shaped, and the adjacent serrated-shaped portions of the barrel both form a blade slot for positioning the serrated-shaped blade, and the blade edge corresponds to the teeth on the serrated shaped edge. A driver unit is installed in the interior cavity to make the blade move along the roller axially to cut the wrapped in the tooth groove automatically when the roller brush is turned on and off.
