A sprinkler apparatus, a flow rate control valve assembly, and a sprinkler irrigation system for providing an even distribution of water across an asymmetrically shaped water receiving area. The sprinkler apparatus comprises a pop-up sprinkler head with a base housing for confiningly receiving a pressurized water flow that actuates a nozzle housing slidingly and rotationally cooperating with the base housing to pop-up into an operating position for discharge of water through at least one pair of nozzle assemblies. The pair of nozzle assemblies comprise an upper nozzle assembly and a lower nozzle assembly near the top end of the nozzle housing. The upper nozzle assembly controllably projects the pressurized water flow for a precisely set distance, while the lower nozzle assembly comprises a vertical slit-shaped aperture through which water is discharged in a curtain effect. Together, the pair of nozzle assemblies achieve a substantially uniform elliptical linear spray pattern with a bias to outermost end. A flow rate control valve assembly is further described and comprises a flow control valve assembly that can be fluidly coupled to a pop-up sprinkler head to controllably supply the pressurized water flow, the flow control valve assembly comprising a water inlet fluidly coupled to a water supply and a water outlet fluidly coupled to the pop-up sprinkler head, the water outlet cooperatively engaging with a rotary disc valve having a tapered passage wherein sliding rotation of the rotary disc valve incrementally adjusts the valve between an opened position and a closed position to control the pressurized water flow through the water outlet.

An object is to effectively remove dirt adhering to a surface to be cleaned and improve supply efficiency of a compressed gas. The injection nozzle of the invention is configured such that a rotating body housing portion is provided in an outer cover, a rotating body is provided in the rotating body housing portion, a rotating body protruding portion is provided in the rotating body, a distal end portion of the rotating body protruding portion protrudes outward through an opening portion provided in the outer cover, a liquid discharge pipe is provided inside the rotating body, and a distal end portion of the liquid discharge pipe is inserted into an insertion hole of the rotating body protruding portion.

A lawn sprinkler is provided that restrains a hydrodynamic water discharge from a flailing fluid nozzle in a manner adapted for distributing watering a user-defined area. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A driving structure for a garden sprinkler comprising: a main body, a sprinkler unit, at least one adjusting base, and at least one driving member. The main body has a main base and an upper cover corresponding to each other, the main base being hollow and having an assembly opening at an end configured to accept the sprinkler unit and for connection to a hose connector; the main base having a recess and a streaming surface, a plurality of first through apertures disposed on the streaming surface corresponding to a plurality of second through apertures with longer lengths disposed on the upper cover; the recess accepting the adjusting base and forming an enclosure with the upper cover; at least one through hole disposed in a middle portion of the main body and defined by integrating the main base with the upper cover, the through hole provided with a positioning baffle.

A sprinkler includes a body having an upper portion removably attached to a lower portion. The upper portion includes a nozzle strip and lower nozzle plate. The lower portion includes a hollow body, a locking plate, and a controller connected to the locking plate. The locking plate is configured to move in a lengthwise direction. The locking plate includes a locking plate tab and a locking plate groove. The lower nozzle plate includes a nozzle plate tab. The hollow body comprises a vertical channel configured to accommodate the locking plate tab in a first position. The nozzle plate tab is arranged beneath the locking plate tab in the first position. The locking plate tab is arranged outside the vertical channel in a second position. The controller is configured to move the locking plate to the first position and to the second position to facilitate removal of the upper portion.

A sitting toilet having a foot health care device attached thereto is disclosed. The sitting toilet contains a main body which includes an accommodation part, which is in front lower end and has an accommodation space to accommodate the foot health care device, and a toilet water tank and a wastewater duct which are formed across the upper end and the rear lower end; and a foot health care device having an inner space to receive a user's feet and a foot washing tank in which a sewage outlet is formed at the lower end. The sitting toilet operates such that the inner space of the foot washing tank opens as the foot health care device slides forward from the accommodation part of the main body, and the foot health care device is accommodated in the main body as the foot health care device slides backward.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.

A multiple nozzle system and device that provides flow control, a nozzle base, the inclusion of a flare or a reversible flare, or a twister attachment, along with various desired directional arm(s) formed from nozzles or the combination of nozzles and elbows, for creating any desired directional angle(s) for each of the directional arm(s). Based on this invention, the water (or angled streams) exiting from the combination of the various directional arm(s) creates an unlimited number of possible resulting fountains or other visual water displays, spray patterns, or designs.

A rotating sprinkler is configured with only three components without need of any other manufactured component. The three components are constituted by a base component connected to a water source, a rotating head component from which a water stream is emitted which is rotatably mounted on an element of the base component, and a gravitating hammer component pivotally mounted on the head component that causes intermittent rotary motion of the head component about a vertical rotation axis by intermittently engaging the emitted stream and providing in response a reaction force. The hammer component is configured to intercept the emitted water stream within an interior space between a deflecting surface and a ramping surface when downwardly pivoted and to urge the intercepted water stream to flow upwardly along the ramped surface and to impinge upon the deflecting surface, causing the hammer component to pivot upwardly prior to being gravitated.
