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. A flow rate control valve assembly comprises a flow control valve assembly that can be coupled to a pop-up sprinkler head to supply the pressurized water flow.

A sitting toilet having a foot health care device attached thereto includes: a main body which includes an accommodation part, which is in the front lower end and has an accommodation space in which the foot health care device is accommodated, 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 in which a user's feet are placed and a foot washing tank in which a sewage outlet is formed at the lower end. The inner space of the foot washing tank in which the user's feet are placed is opened 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 adjustable arc irrigation spray nozzle can include one or more features including a dual orifice, a multi-trajectory ramp, radial ribs, an impedance wall, and/or a variable orifice.

A multi-mode sprinkler adjustable for part or full circle operation to irrigate a selected area is provided. The sprinkler includes a nozzle for dispensing fluid, a set of gears for rotating the nozzle, and an arc setting mechanism that cooperates with the set of gears. The arc setting mechanism comprises a fixed trip for switching to a first direction for the nozzle and an adjustable trip movable relative to the fixed trip for setting an arc of rotation for the nozzle in the part circle mode. The arc setting mechanism also includes a toggle for engaging the fixed trip and the adjustable trip to switch between a first direction and a second direction when in the part circle mode. In the full circle mode, the adjustable trip is deflected radially outward, and the fixed trip deflects radially outward as it passes the toggle, allowing continuous rotation of the nozzle. A memory arc function is also provided, in which the arc setting mechanism returns to an originally set arc of rotation after mishandling of the sprinkler.

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 aimable sprinkler is disclosed. The sprinkler can be mounting on an end of a traveling sprinkler system that moves in a linear direction or one that rotates about a center pivot tower. The sprinkler can include a base for connecting to the traveling sprinkler system and a turret coupled to the base so as to move in both yaw and pitch directions relative to the base. The sprinkler aims at discrete points within an irrigation area to achieve an even distribution of water.
