20110079662 | Driving Device of a Sprinkler and Swinging Sprinkler with the Driving Device - 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. | 04-07-2011 |
20110095101 | Sprinkler Having Adjustable Sprinkling Pattern - 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. | 04-28-2011 |
20120056014 | Sprinkler device - 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. | 03-08-2012 |
20120104118 | Sprinkler adapter device having multiple rates of output flow - 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. | 05-03-2012 |

20100264238 | SPRAY NOZZLE - 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. | 10-21-2010 |
20120097760 | GEAR TYPED SPRINKLER ASSEMBLY - A sprinkler assembly has a body, a base assembly, a wheel, a gear assembly, a discharging valve, a spraying head and a cover. The wheel is rotatably mounted in a wheel chamber in the base assembly and has a driving gear. The gear assembly has gear sets engaging each other. Each gear set has a driving gear and a driven gear coaxially mounted on the driving gear. The driving gear has a number of teeth different from that of the driving gear. The driving gear of one of the gear set engages the driving gear on the wheel. The discharging valve has at least one discharging hole. The spraying head is coaxially connected rotatably to the discharging valve and has at least one aligning hole selectively aligns respectively with the at least one discharging hole in the discharging valve. | 04-26-2012 |
