A rotary sprinkler in accordance with an embodiment of the present disclosure includes a riser with a nozzle assembly rotatable mounted thereon. The nozzle assembly includes a pressure regulator and flow control element.

A rotary tank cleaning spray nozzle assembly which includes a stationary housing, a rotary housing for rotation about a central axis of the stationary housing, and a nozzle carrying hub supported by the rotary housing for rotation about an axis transverse to the axis of the stationary housing. A support rod extends through the rotary housing and into the stationary housing with a lower end supporting the underside of the rotary housing and the upper end being secured by a retainer. The retainer is releasable to permit removal of the rotary housing and nozzle hub from an underside of the stationary housing. A fluid driven drive for the rotary housing and nozzle hub includes a pair of removably mounted bevel gear rings. In one embodiment, liquid lubricating, frustoconical, high load carrying bearings support rotatably.

A water jet device for rotary massage includes a seat providing an outlet and a cavity; a cover providing an inlet; a separating member, a rotary shaft, an impeller and a rotor received in the cavity; at least one inclined water ejection port disposed on the separating member and communicating with the inlet; the impeller is mounted between the rotor and the separating member; the rotor is in the outlet, a plurality of curved grooves are formed on the periphery of the rotor; a track assembly includes an annular rail having ascending and descending sections formed on an inner bottom of the seat, and sliders formed on an underside of the impeller; water flowing through the water ejection port rotates the impeller, further drives the rotor to rotate, and the fluctuation of the impeller and the rotor drives the water fluctuates, thus form intermittent and dynamic annular water sprays.

A showerhead assembly is provided which includes a housing having a primary conduit, a front cover with one or more nozzles projecting therefrom, and a gear assembly. The front cover and the housing are affixed so as to form a cavity, wherein the gear assembly is assembled therewithin. The primary conduit is in fluid connection with the gear assembly, which is in fluid connection with the one or more nozzles so as to transport water therethrough. Moreover, a portion of the gear assembly is in toothed engagement with the nozzle(s). In this manner, as water enters the gear assembly, its components rotate and ultimately cause the nozzle(s) to rotate. The nozzles are configured to spray a flat, fan shaped spray of water, and can do so as at the same time as they rotate. As such, the showerhead assembly produces a pinwheel-like, massaging spray pattern. The nozzle can rotate synchronistically.

A net water outlet device includes a main body and an outlet cover plate. The outlet cover plate is disposed at one end of the main body, the other end of the main body is an inlet end. The outlet cover plate is disposed with a first outlet hole group and a second outlet hole group arranged concentrically; therein, the outlet direction of the first outlet holes are configured so that: the axis of the outlet cover plate projects to the circumference of each first outlet hole, making the axis of the outlet cover plate and the tangent line of the circumference of each first outlet hole jointly define a first plane, the outlet direction of the first outlet holes are in the first plane, forming a first intersection angle with the projection of the axis of the outlet cover plate.

An outlet device with multilevel rotary massage water has a main body, an operating unit, a switching unit and a driver. The main body has a cavity for accommodating the driver and the cavity has inlets with at least two different directions; the water from the inlet flows into the cavity and rotates the driver; the driver rotates a massage driving outlet unit, and the direction of the flow of the massage driving outlet unit periodically changes with the rotation to form the massage water; the operating unit drives the switching unit to move so that at least two inlets are both open or one of the inlets is closed; then, the velocity of the flow in the cavity is changed, so that the rotational speed of the driver increases or decreases correspondingly and the switching frequency of the massage water also increases or decreases accordingly.

A rotary tank cleaning spray nozzle assembly which includes a stationary housing, a rotary housing for rotation about a central axis of the stationary housing, and a nozzle carrying hub supported by the rotary housing for rotation about an axis transverse to the axis of the stationary housing. A support rod extends through the rotary housing and into the stationary housing with a lower end supporting the underside of the rotary housing and the upper end being secured by a retainer. The retainer is releasable to permit removal of the rotary housing and nozzle hub from an underside of the stationary housing. A fluid driven drive for the rotary housing and nozzle hub includes a pair of removably mounted bevel gear rings. In one embodiment, liquid lubricating, frustoconical, high load carrying bearings support rotatably.

An auto-swinging shower which drives a water outlet assembly to swing without external power, containing a water flow-through part, a water outlet assembly, an impeller and a transmission assembly. The water flow-through part is provided with a water flow-through cavity. A water inlet end of the water outlet assembly is pivotally engaged with a water outlet end of the water flow-through part and communicates with the water flow-through cavity. The impeller is rotatably engaged in the water flow-through cavity. An input end of the transmission assembly is in transmission connection to a rotating shaft of the impeller. An output end of the transmission assembly is in transmission connection to the water outlet assembly.

A sprinkler that includes an internal flow adjustment valve is provided. The valve enables an operator of the sprinkler to selectively shut off, turn back on, or adjust the flow of water through the sprinkler while a riser of the sprinkler is in its extended position. The valve includes a valve seat disposed on an internal flow tube and a valve plunger having an actuation shaft and a throttle nut. An outboard end of the actuation shaft can be accessed and rotated at a riser cap, which causes vertical movement of the valve plunger as threads on an inboard end of the actuation shaft engage a threaded passage disposed in the internal flow tube. Vertical movement of the valve plunger causes movement of the throttle nut relative to the valve seat and opening and closing of the valve. The throttle nut and the valve seat may have corresponding dual helical surfaces.

A switching valve includes a base including a bottom wall and a side wall that extends from the bottom wall of the base along a circumferential direction of the bottom wall, a body that can couple to the base to define a cavity between a bottom plate of the body and the bottom wall and the side wall of the base, in which the bottom plate includes two through holes that are each fluidly coupled to the cavity, two sliders disposed within the cavity, and two driving rods each movably coupled to one of the two through holes of the body, in which each driving rod can move relative to the two through holes to block or unblock each respective through hole. Each slider can slide responsive to movement of one of the two driving rods such that only one through hole is unblocked at one time.
