Cleaning device with liquid conducting universal joint
Abstract:
Cleaning device includes shaft that interfaces with fluid source and defines conduit. Mounting couples to cleaning element and includes interior and apertures. Liquid conducting universal joint is coupled with mounting and shaft. Joint includes a nozzle coupled to shaft that is in fluid communication with conduit. Nozzle includes nozzle mating feature defining nozzle aperture. Joint includes rotational element having first mating feature rotationally coupled with nozzle mating feature and is rotatable about radial axis of nozzle mating feature and second mating feature. Rotational fluid conduit extends between mating features. Joint includes connector coupled with mounting that defines connector conduit. Connector mating feature is rotatably coupled with second mating feature and is rotatable about radial axis of second mating feature that is substantially orthogonal to radial axis of nozzle mating feature. Cleaning device defines rigid fluid path that enables rotation of mounting without bending components that define fluid path.
