    摘要： The present disclosure discloses a blade driving structure, including a planetary gear transmission mechanism, a fixing portion is provided on a second side, a sun gear of the planetary gear transmission mechanism is fixedly connected to the fixing portion, a gear ring of the planetary gear transmission mechanism is connected to a rotating cylinder, and a planet carrier acts as a transmission output and drives a second driving shaft to rotate through a coupling; a reciprocating motion structure includes a rotating body, the second driving shaft is in circumferential transmission connection with the rotating body, and a track of the rotating body engages with a driving member to convert a rotation of the rotating body driven by the second driving shaft into a reciprocation of the driving member. The solution of the present disclosure uses the planetary gear transmission to drive the reciprocating motion structure to reciprocate by means of rotation. In addition, a fixed end cap is not required to be arranged on one end of a brush roller (i.e., the rotating cylinder), and no output gear rings and idler gear pairs are required. The present disclosure further discloses a hair cutting rolling brush using the blade driving structure and a cleaning device equipped with the hair cutting rolling brush.

    摘要： A cleaning device and a sweeper, the cleaning device includes a driving module (12), which includes a lifting driver (121); a lifting module (14), which includes a first shaft sleeve (141) and a second shaft sleeve (142), the first shaft sleeve (141) is connected with a power output shaft (122) of the lifting driver (121), a screw mechanism is formed between the first shaft sleeve (141) and the second shaft sleeve (142); and a cleaning module (13), which includes a cleaning member (131) connected with the second shaft sleeve (142); the screw mechanism is at least is subjected to a first driving force of the power output shaft (122) of the lifting driver (121) to drive the cleaning member (131) to perform a descending motion relative to the lifting driver (121), and is subjected to a second driving force to drive the cleaning member (131) to perform an ascending motion relative to the lifting driver (121). The cleaning device and the sweeper may prevent the cleaning member (131) from polluting a carpet, effectively protect the carpet, meanwhile, may prevent the cleaning member (131) from causing secondary pollution to the cleaned floor after the sweeper finishes cleaning, and improves a cleaning effect of the sweeper.

    摘要： Provided is a cartridge (100) attachable to a wet cleaning apparatus, in particular a wet floor cleaning apparatus. The wet cleaning apparatus has a volume displacement device (102) for dosing surface treating agent from the cartridge when the cartridge is attached to the wet cleaning apparatus. The cartridge comprises a chamber (106) for containing surface treating agent. The cartridge also has an interfacial portion (107) for interfacing with the volume displacement device during attachment of the cartridge to define a dosing assembly (108). A first valve (116) is configured to either enable fluid to be moved out of the chamber or to be moved into the chamber by operation of the volume displacement device. A second valve (120) is configured to enable fluid to exit the dosing assembly, for example either during displacement of fluid in the cartridge by the fluid moved into the chamber by the volume displacement device, or during a fluid expulsion action of the volume displacement device that is subsequent to an initial action of the volume displacement device that moves the fluid out of the chamber via the first valve. Each of the first and second valves enables restriction of passage of the surface treating agent therethrough prior to attachment of the cartridge. Further provided is a cleaning assembly comprising a cartridge and a wet cleaning apparatus.
