摘要： A watering nozzle includes a handle with a trigger to control a valve in an inlet pipe received in the handle. An outlet pipe is connected to the first pipe and an adjusting member has a rear end connected to the outlet pipe. A plurality of first outlets are defined radially in the adjusting member. A rotatable head is threadedly and rotatably connected to the adjusting member and includes a plurality of chambers and each of which has an outward cone-shaped inner periphery, a plurality of tiny holes and elongate holes. The adjusting member is movable linearly when rotating the rotatable head so that water is introduced into one of the chambers via the first outlets so as to generate different watering patterns.

摘要： An invention of a flow-regulating valve for a nozzle comprise a valve chamber with an inlet and outlet, a valve axle with a notch passage and a block section for regulating the flow of the fluid, and a regulative handle joined with the valve axle by a set of joining tray to drive the valve axle in the various angles. The above block section is set in the midsection of the valve axle and with an annular groove to clasp a annular block washer for blocking and shut off the flow of the fluid, and two annular washers set on two ends of the valve axle for avoiding the leakage from the gaps between the valve axle and the valve chamber. The defended fences are set on the inlet and the outlet of the valve chamber for avoiding the annular block washer to get off as the valve axle turning.

摘要： A watering nozzle assembly includes a core tube received in the barrel of the nozzle. A first seal ring and a second seal ring are respectively mounted to a second end of the core tube, and a plurality of apertures are defined radially in the core tube and located between the first and second seal rings. A control rod pivotably connected to an operation bar movably seals the first end of the core tube. A nozzle is threadedly connected to the core tube. A block is fixedly connected to the second end of the core tube and removably seals the nozzle. The nozzle cab be moved relative to the core tube to allow water flowing from the gap between the block and the stepped surface in the nozzle. The first and second seal rings ensure that the nozzle assembly does not leak whichever status it is operated.
