Cleaning heads, vacuum cleaners, and cleaning systems

Abstract

This invention discloses a cleaning head, a vacuum cleaner, and a cleaning system. The cleaning head includes a housing for moving on a surface to be cleaned. The housing defines a fluid channel, and further defines a suction chamber fluidly communicating with the fluid channel and a cleaning chamber fluidly communicating with the suction chamber. The suction chamber and the cleaning chamber are fluidly connected through at least one connecting port. The cleaning head also includes a cleaning device for cleaning the surface. The cleaning device includes a drive motor, a transmission structure, and a cleaning component. The cleaning component is disposed within the cleaning chamber. The drive motor drives the cleaning component to move along a motion trajectory through the transmission structure. The motion trajectory includes a first segment and a second segment. In the first segment, the cleaning component leaves the surface to be cleaned; in the second segment, the cleaning component contacts the surface to be cleaned to sweep dirt from the surface towards the connecting port.
