Abstract: A column type coreless motor is provided, having has no iron loss, low heat loss and high efficiency. The motor includes a stator, a rotor and a motor housing, wherein the rotor is a column type structure with a U-shaped annular groove, and the stator is placed in the U-shaped annular magnetic field of the rotor. In some embodiments, the stator is made by solidifying a coil therein with a thermosetting material through a pressure device, and the coil is wound by combining multiple enameled wires into a phase line, successively superposing three-phase lines, and winding each phase line in a toothed circle shape. The rotor is provided with a heat dissipation fan, and the fan discharges the heat generated by the coil out of the motor through a heat dissipation air passage in the motor housing, effectively ensuring the heat dissipation effect of the motor.

Abstract: A docking station includes a base and a cleaning member assembly. The cleaning member assembly includes at least one cleaning member, a first bracket, a second bracket, and a power source. Each of the at least one cleaning member is mounted on the first bracket and the second bracket. One of the first bracket and the second bracket is a fixed bracket, and the other is a movable bracket. The movable bracket is driven to reciprocate along a straight line, in order to drive each the cleaning member to swing relative to the first bracket around a central axis.
