A sprinkler includes a base, a tubular body disposed on the base, at least one control assembly mounted to the tubular body, and at least one nozzle set which has a plurality of nozzles aligned in a row and is disposed on the tubular body. The control assembly includes at least one push portion mounted with at least one connecting member which is pivotally connected to at least one guiding member with a plurality of sliding slots. The sliding slots are inserted by the nozzles for allowing the nozzles to be moved back and forth selectively. By movement of the push portion in an axial direction of the tubular body caused by manual operation, the guiding member is also moved radially to drive at least one of the nozzles to incline in turn.

An improved showerhead assembly is provided for use with handheld showerheads. The handheld showerhead includes an elongate handle and a showerhead face including one or more nozzles for spraying water. In addition, the showerhead assembly includes a hollow mount for affixing to the male threaded pipe found in a shower stall. The mount includes a “C” shaped receptacle for holding the handheld shower assembly, an inlet for receiving water, as well as an outlet for expelling water to a flexible hose, which in turn is connected to the handheld showerhead. In addition, the mount includes supplemental spray assemblies which are affixed to the left side, right side or both sides of the “C” shaped receptacle. The supplemental spray assemblies can be rotated so as to expel water through different spray nozzle configurations.

The present invention provides a cleaning machine capable of selecting a spray head independently of a rotational phase of a nozzle. The cleaning machine includes a slide, a pump, a main valve, a nozzle switching valve, a compressed air source, a swivel joint, a motor, and a nozzle block. The nozzle switching valve has an inflow chamber, a first chamber, a second chamber, a stem, a conical first valve element abuttable against the first valve seat, a conical second valve element abuttable against the second valve seat, a piston, and a spring. The swivel joint has a swivel housing, a swivel shaft, a first nozzle flow path and a second nozzle flow path. The nozzle block has a first nozzle connected to the first nozzle flow path and a second nozzle connected to the second nozzle flow path.

Provided is an unmanned aerial vehicle including: a discharge port configured to discharge contents in a container; an expansion/contraction unit configured to connect the discharge port and the container and be expandable; and a discharge position control unit configured to control expansion/contraction of the expansion/contraction unit.

Apparatus for cleaning a surface with a liquid jet, the apparatus having: a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end; a first motor-driven drive assembly configured to engage the primary fluid conduit and turn the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a first motor configured to engage the first motor-driven drive assembly; a section of the primary fluid conduit being inside of an adjacent penetration sleeve; a section of the penetration sleeve being inside of a piston sleeve; the piston sleeve configured to engage the penetration sleeve and move the penetration sleeve back and forth along a penetration-sleeve linear path over a primary-fluid-conduit exterior surface; an actuator configured to engage the piston sleeve and move piston sleeve back and forth along a piston-sleeve linear path; a penetration-sleeve end being attached to an extension sleeve that has a first end and a second end; the extension-sleeve second end being attached to a pull rod or a pull cable; the pull rod or the pull cable being attached to a nozzle anchor and configured to pull on, push against, or release tension from the nozzle anchor as the penetration sleeve moves back and forth along the penetration-sleeve linear path; the primary-fluid-conduit fluid-exit end being attached to a flexible conduit; the flexible conduit being attached to a nozzle tip having the nozzle anchor thereon; and a continuous fluid-flow channel that extends from the primary-fluid-conduit fluid-intake end through the flexible conduit.

A device cleans a core engine of a jet engine. The device has: a nozzle installation configured to introduce a cleaning medium into the core engine; a connector configured to connect the device in a rotationally fixed manner to a shaft of a fan of the jet engine; and a line connection configured to supply the cleaning medium, the line connection being connected to the nozzle installation by a rotary coupling. The nozzle installation has first contact faces configured to bear axially on fan blades of the fan, the first contact faces being configured for defined positioning of the nozzle installation relative to the jet engine.
