Abstract: A brushroll is provided. The brushroll includes a rolling body and a plurality of brush strip sets. The plurality of brush strip sets extend along an axial direction of the rolling body and are arranged at intervals along a circumferential direction of the rolling body. The brush strip set includes a first brush strip and a second brush strip. Both the first brush strip and the second brush strip are protruded from an outer surface of the rolling body, and are continuous along the axial direction of the rolling body. A circumferential spacing between the first brush strip and the second brush strip in a same one of the brush strip sets is less than a circumferential spacing between two adjacent ones of the brush strip sets.

Abstract: A telescopic conductive tube is provided, including a conductive assembly. The conductive assembly includes an isolating guide, an isolating restraining tube, a rail, a wire, a guiding rod and a conductive spring. The conductive spring is sleeved on the guiding rod and electrically connects with the wire. The guiding rod and the conductive spring are accommodated within the isolating restraining tube. The isolating restraining tube is accommodated within the isolating guide. The wire is accommodated within the rail. The isolating restraining tube has one end inserted into the rail. The rail is slidable relative to the isolating guide. When sliding into the isolating guide, the rail slides along an outer wall of the isolating restraining tube, and the conductive spring is compressed by a bottom of the rail.

Abstract: The present disclosure provides a dry-wet separation cleaning floor brush. The dry-wet separation cleaning floor brush includes a housing, a stiff roller brush and a soft roller brush, wherein the housing is provided with a partition plate dividing the inner part of the housing into a first storage chamber and a second storage chamber which are disconnected to each other, wherein the stiff roller brush is partially contained in the first storage chamber and is movably connected to the housing, and the stiff roller brush partially protrudes the housing; and the soft roller brush is partially contained in the second storage chamber and movably connected to the housing, and the soft roller brush partially protrudes the housing.

Abstract: The present disclosure provides a telescopic conductive tube, including a conductive assembly and a telescopic assembly. The conductive assembly is mounted to an outer wall of the telescopic assembly and extends along a longitudinal direction of the telescopic assembly. The conductive assembly includes an upper housing, a lower housing, a conductive wire, an elastic conductive wire, a first electrode pin and a second electrode pin. The elastic conductive wire is accommodated within the telescopic assembly. The lower housing has an end fixed to the telescopic assembly. The conductive wire has an end electrically connected with the first electrode pin and an other end electrically connected with the elastic conductive wire. The elastic conductive wire has an end disposed away from the conductive wire and electrically connected with the second electrode pin. The conductive wire is sandwiched and fixed between the upper housing and the lower housing.
