  • Patent number: 7566012
    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.
