  • Publication number: 20110061759
    Abstract: A tube assembly includes an outer tube with ribs in the inner periphery thereof and a sleeve is mounted to the outer tube and an operation unit is located in the outer tube. The operation unit includes a first part and a second part which is threadedly connected to the first part. The second part includes multiple expandable plates extending axially therefrom. An inner tube unit has a connection member connected to an end thereof and the connection member is fixed to the first part and includes a tapered flange which is moved to control the expandable plates to contact or removed from the inner periphery of the outer tube when adjusting the inner tube relative to the outer tube.

  • Patent number: 7611074
    Abstract: A watering nozzle includes a water volume detection unit received in the barrel of the watering nozzle and the water volume detection unit has two stationary members and a rotatable member which is rotatably connected between the two stationary members. The rotatable member has a magnet connected thereto which is rotated with the rotatable member when water passes through the rotatable member. A display unit is connected to the barrel and has a circuit board and a display member which is electrically connected to the circuit board. The times of revolution are detected by a magnetic spring switch on the circuit board and transferred into digits on the display member to show the volume of water that flows through the rotatable member and the nozzle unit connected to the barrel.

  • Patent number: 7080795
    Abstract: A garden nozzle includes a barrel and a handle to be connected with a hose and a tube is movably received in the barrel and connected with a pattern switching button which is connected to the handle. A shank with a spiral groove extends through a pattern member rotatably mounted to a front end of the barrel and a sleeve which is received in the tube. The pattern member is fixed to the shank. The sleeve includes a ridge which is movably engaged with the spiral groove so that when pulling the pattern switching button, the tube and the sleeve are moved backward so as to drive the shank and the pattern member to rotate.

  • Patent number: 7000855
    Abstract: A garden nozzle includes a core piece received in the barrel of the nozzle and the core piece includes an outlet allowing water to come out therefrom. The core piece is in communication with the path defined in the handle and water is provided via the path. A movable member is movably mounted to the core piece and is driven by an operation member connected to the barrel and can be operated by one finger of the user's hand grasping the handle. The position of the movable member changes the relative positions of the outlet and the opening located at a center of the cone-shaped inner periphery of the movable member, so as to obtain different pattern of watering.
