Abstract: A sprinkler has a sprinkling device, and an inlet controlling device and an end cap respectively mounted on two opposite ends of the sprinkling device. The sprinkling device has a casing having outlet holes, and two regulating panels having regulating slots, two regulating wheels, two transmission rods and a cover having limit slots mounted on the casing. The outlet holes, the regulating slots and the limit slots respectively align with each other and are mounted around multiple nozzles. Turning the regulating wheels forces the nozzles to bend through the regulating panels so the sprinkler has a variety of sprinkling patterns to be suitable for every place where the sprinkler is placed. The nozzles are individually manufactured and are easily mounted on the casing and replaced.

Abstract: A sprinkler device has an inlet-driving assembly mounted in by a rotary seat, and an outlet valve whose one end is mounted through the rotary seat and in the inlet-driving assembly and the other end has multiple through holes. A spray nozzle assembly is mounted on the outlet valve and has multiple first and second spray holes communicating with the through holes of the outlet valve and the rotary seat, and has a block flange formed around a periphery thereof. A first and a second O-rings are sequentially mounted on the block flange. One end of the spray nozzle assembly is mounted through a cover mounted on the inlet driving assembly. Subjected to a same pressure from water filled in all parts of the sprinkler device, the first and second O-rings reduce friction between the block flange and the cover to enable a smooth rotation of the spray nozzle assembly.

Abstract: A sprinkler adapter device having multiple rates of output flow of a sprinkler has an inlet-driving unit, an outlet valve and a discharge rotor. The inlet-driving unit has a body and a cover combined with the body, respectively having a first connection portion and a second connection portion communicating with each other. The discharge rotor is collaborated with the outlet valve and is driven by water stream. The discharge rotor and the outlet valve respectively have upper valve holes and lower valve holes corresponding to each other. Each of the upper valve holes and the lower valve holes has a guide plane. By respectively adjusting the overlapping area between the upper valve holes and the lower valve holes and the guide planes thereof, water can be discharged at different flow rates intermittently, thereby simplifying the sprinkler adapter device with a sprinkler and allowing to demonstrate different water spray patterns.

Abstract: A driving device of a sprinkler has a housing, a diversion assembly and a gear set mounted in the housing, a switch assembly mounted on a front open end of the housing and a nozzle mounted through the switch assembly and connected to the diversion assembly. In the switch assembly, as an inner ring is pushed, a resilient strip and a switch valve swing so the gear set drives the nozzle in different directions. Since switch rings securely engage the inner ring, when a limit of the nozzle collides with a stop of one of the switch rings, the switch ring and the inner ring immediately rotate to push a switch rod and to switch rotating directions of the nozzle. Therefore, the switch rings are not damaged easily for improved durability.

Abstract: A spray nozzle has a casing, an inside plug, an inside seal, an outside seal, an outside plug, an adjustment lever assembly and a nozzle head. The casing has a handle and a neck. The inside seal, outside seal, outside plug and nozzle head are mounted sequentially in and on the casing. The inside and outside seals are tubular and has sufficient surface areas to provide sufficient sealing characteristics. The adjustment lever assembly is longitudinal and mounted pivotally on the casing to allow fine adjustment of a flow rate of the spray nozzle.

Abstract: A water sprinkling assembly includes a base having a first L shaped tube and a second L shaped tube respectively and oppositely provided on an inner side face of a recessed area in the base, and a sprinkling disk rotatably connected to the base and having multiple sprinkling holes and two opposed blind holes with a water guiding track formed on a bottom face of the sprinkling disk to connect the two blind holes together such that when the two blind holes are aligned with the first outlet and the second inlet of the base respectively, the water will be guided directly from the first outlet to the second inlet and eventually flows out of the base via the second outlet of the base for a different application.

Abstract: A dual-axis rotating sprinkler has a nozzle, an adjusting assembly, a rotating assembly and an adapting tube. The adjusting assembly is attached to the nozzle. Pivoting the adjusting assembly easily changes the elevation angle of the nozzle to change the spray area. The rotating assembly is attached to the adjusting assembly. The adapting tube is mounted around the rotating assembly, connects to the water pipe to allow the water passing through the adapting tube and filling into the rotating assembly. The water drives the rotating assembly to rotate the adjusting assembly. Therefore, the dual-axis rotating sprinkler rotates by the rotating assembly to spray in all directions and can be pivoted by the adjusting assembly to change the spray area.

Abstract: A leakage proof device for a sprinkler nozzle includes a flange adapted to be formed on a peripheral edge of the isolator, an annular wall adapted to be formed on a peripheral edge of the controlling disk to be on top of arcuate seats which are formed on an inner side of the controlling disk and an O ring sandwiched between the flange and the annular wall to stop leakage between the isolator and the controlling disk.

Abstract: A controlling device for a sprinkler includes multiple seals detachably received in the tube in a watertight manner. Each seal has outlets defined in a top face of the seal and passages defined to respectively communicate with a corresponding one of the outlets. Multiple controlling rods are linearly and movably received in the tube to engage with a bottom face of the seals so as to selectively block the communication between the passage and the outlets such that water inside the tube is controlled to be sprinkled out of the tube.

Abstract: An actuation mechanism is used with a sprinkler to allow water to flow out of the sprinkler or to shut off the flow of water. Rather than a conventional trigger, the activation mechanism uses a pushbutton assembly that can be toggled open or closed. This allows the person directing the sprinkler to use the sprinkler without undue stress on the hand and fingers from having to squeeze the conventional trigger. The actuation mechanism is comprised of a pushbutton, a guiding member, a limiting sleeve and a shell. The pushbutton, guiding member and limiting sleeve are housed in the shell. The pushbutton is attached to the guide member that selectively slides in the limiting sleeve. A connecting rod attached to the guiding member interfaces with the valve in the sprinkler and actuates the flow of water.
