A gardening sprinkler may include a main body, a sprinkler member, and a control base, and the main body has a sprinkler base and an upper cover which are adapted to fit together. The sprinkler base is a hollow tube and has an opening at one end thereof, the sprinkler member is positioned into the sprinkler base through the opening, and a water inlet member is connected to the sprinkler base through the opening. The sprinkler base has a concaved portion and a sprinkler surface, and the concaved portion is formed adjacent to the other end of the opening. The sprinkler surface comprises a row of first through holes which are arranged axially, and upper cover has a row of second through holes at positions corresponding to the first through holes.

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.

An oscillating sprinkler may include a main body, a water outlet tube, two moving members, a cover, and a c-shaped control ring. The main body has a connecting portion and a connecting tube respectively formed at two ends thereof, and the connecting tube is connected to a water source. The water outlet tube is cut in axial direction to form a water outlet portion, and a plurality of water outlet holes are separately formed thereon. A first elastic strip is installed in the interior of the water outlet tube, and a plurality of elastic nozzles are formed on the first elastic strip at positions corresponding to the water outlet holes.

Rotary nozzles and deflectors for use with rotary nozzles are provided. The deflector includes a number of flutes that deliver fluid streams radially outwardly from the deflector. Fluid striking the flutes of the deflector cause the deflector to rotate, and the flutes subdivide fluid impacting deflector into multiple fluid streams that are distributed radially outwardly to surrounding terrain as the deflector rotates. Each of the flutes have the same curvature, although they may have different inclinations to distribute fluid streams at different trajectories. The flutes may also include blocking and downward-facing features at the ends of the flutes to improve the evenness of the fluid distribution in the irrigation coverage area.

A building monitoring and control system in furtherance of engaging a detected and targeted threat to persons in or about the building is provided. The system is characterized by a threat detection module, a threat targeting module, a threat tracking module, and threat engaging assemblies. The threat detection module is provided in the form of a multi-modal sensor array or network system deployable or integral with a monitored building. Threat targeting and tracking modules are operatively linked to the threat detection module, and each other. Threat engaging assemblies, in the form of water cannons selectively deployable or integral with a monitored building, are operatively linked to at least the tracking module in furtherance of disrupting a located and trackable threat with water discharged from multiple water discharge nozzles of the water cannons.

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 sprinkler includes a nozzle assembly attached to an upper portion a the sprinkler. The nozzle assembly includes a nozzle strip having nozzles and an angle plate in contact with the nozzle strip. The angle plate includes angle plate grooves and teeth. The nozzles extend through the angle plate grooves. The upper portion includes nozzle openings that correspond to the angle plate grooves. The nozzles extend through the nozzle openings. The angle plate grooves overlap with the nozzle openings to form an adjustable intersection opening. The sprinkler includes a controller having a knob extending outside the sprinkler and teeth positioned inside the sprinkler. The teeth mesh with the teeth of the angle plate. The controller drives the angle plate and an axis of at least one of the plurality of nozzles extending outside the sprinkler varies based on a position of the angle plate.

A cone valve assembly including an upper valve member with a conical top portion and a stepped and spiraled top surface and a lower valve member including a central opening with a stepped and spiraled valve surface surrounding the central opening. The upper valve member is mounted in the lower valve member such that the lower valve member is rotatable and axially movable relative to the upper valve member. Rotation of the lower valve member allows for the adjustment of an arcuate slot opening that provides a conically shaped discharge stream of water from the cone valve nozzle assembly directly onto the rotating distributor to provide the desired arc of sprinkler coverage.

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.
