  • Publication number: 20090020169
    Abstract: An easy-type water pressure reducing apparatus comprises a connecting tube having a bore extending through an inlet end and an outlet end. The bore has an annular seat with a smaller-diameter inlet chamber integrally extending at both sides to which a movable element with an inlet port to receive a spring element is mounted. The movable element also includes positioning guide blocks to fit to water-guiding vents of the inlet chamber, and a ringed groove with a sealing ring to abut tight against the inlet chamber, forming a back-and-forth movable positioning space there-between. Therefore, when water pressure at the outlet end is larger than that at the inlet end, water flow blocked by a water plug of the movable element will push the movable element towards the inlet end, compressing the spring element and closing the water-guiding vents gradually to reduce the water flow and stabilize the water pressure thereby.

  • Publication number: 20080217427
    Abstract: A multi-functional sprinkling apparatus structure comprises an outlet mount with support lugs to fix on top of a water motor, and a water-guiding member transversely mounted to assembly holes of the support lugs. The assembly holes have water ducts fluidly connected to water-inlet passages of the water-guiding member. A rotary member with a channel and a water shield with actuation holes are pivotally mounted to the middle section of the water-guiding member. The channel of the rotary member has multiple outlets with spray nozzles attached thereto to generate various sprays, and recesses to engage with a movable elastic element mounted to the water-guiding member. The rotary member can be switched to change the outlet matching to a water-discharge orifice of the water-guiding member for a certain spray. The water shield can be bent to one side to adjust the angle of the water-guiding member and the rotary member for sprinkling.

  • Patent number: 7422162
    Abstract: The present invention relates to an automatic water inlet switching device for an oscillating sprinkler that has a sprinkle control unit having a blade equipped gear transmission set housed therein, working together with a water inlet switching device having an operation unit and a movable swinging seat. The bottom of the movable swinging seat is provided with two water stop ends in opposite to two outlet holes defined on a coupling unit with a concaved bounded space placed at the center thereof. An action stick of the operation unit is operable inside the bounded space so that in the water inlet switching operation the swinging angle of the action stick is limited within the bounded space and the action stick will move against the push end thereof so as to produce a built-up force to instantaneously spring away the movable swinging seat no matter what the water pressure is high or low in operation.

  • Patent number: 7419105
    Abstract: A spray oscillating control apparatus for sprinklers is equipped with a sprinkling control assembly to swing a spray body into different angles wherein a gear train assembly with an impeller is mounted into the sprinkling control assembly and work in linking mechanism with a spray oscillating control apparatus composed of a water duct having two inlet orifices and a spray control device having a linkage gear wheel and two covering blocks. The linkage gear wheel is directly meshed with one matched gear of the gear train assembly and the two covering blocks are matched to the two inlet orifices, permitting the linkage gear wheel and the two covering blocks to rotate along with the gear train assembly and, thus, switch the amount of intake water supply in a gradual manner so that spray sprinkled can oscillate rhythmically from far-to-near and near-to-far in distance, achieving even distribution of the spray onto a lawn.

  • Patent number: 7284714
    Abstract: A water shutoff and discharge control apparatus for sprinklers comprises a water intake apparatus mounted to a support seat and swung back-and-forth by a sprinkling control assembly. The water intake apparatus has a tube with a platform and multiple outlets thereon, and both end sections of the tube have multiple control channels each connecting to the interior of the tube for the extension of a control rod there-through. Each control rod has a flat surface with a water-sealing member and a water-sealing area disposed thereon to match to the outlet, permitting the water-sealing member to abut watertight against an internal plane surface of the platform and slide along with the movement of the control rod to correspond to the outlet for water shutoff/discharge control thereby. Besides, the contact area between the control rod and the platform can be reduced, facilitating easier and more efforts-saving operation of the control rod thereby.

  • Patent number: 7258286
    Abstract: A water shutoff and discharge control device for sprinklers comprises a water intake assembly mounted to a support seat and swung back-and-forth by a sprinkling control assembly wherein the water intake assembly has a tube with multiple bores drilled thereon for the mounting of a sealing strip equipped with multiple spray nozzles and water-sealing areas. Both end sections of the tube are disposed multiple control channels each connecting to the interior of the tube for the extension of a control shaft with a plug mounted thereto. Each plug having an inlet aperture and an abutment surface is corresponded to a water-sealing area of the sealing strip to reveal a movement space there-between, permitting the plug flushed by the water flow to climb upwards and, depending on the movement of the control shaft, to switch in position relative to the spray nozzle for easy control of water shutoff or discharge thereby.

  • Patent number: 7255291
    Abstract: A multifunctional sprinkler structure comprises a water motor having an outlet seat and a top cover mounted to a top-end side, and two adjusting seats and a water supply seat assembled onto a bottom-end side. The bottom-end side of the water motor has a guide groove with a restrictive hole for the extension of a switch shaft there-through. The outlet seat has a water-discharge chamber with multiple barriers extending thereon corresponding to an impeller of the water motor, and an oblique-extending central guide port matching to a spray nozzle having multiple water-guiding ribs obliquely extending towards the same direction therein. Therefore, the barriers of the outlet seat and the water-guiding ribs of the spray nozzle are utilized to correspond to the direction of the water flow so that the water discharge can be easily switched to eject either in more direct and forceful column-like spray or in more expanding spray.
