摘要： A control structure capable of adjusting water volume and controlling water supply contains: a body, a fixer, a valve stem, an adjuster, and a controller. The body includes a water outflow segment for connecting with a watering tool, an accommodation groove for accommodating the fixer and the valve stem. The fixer includes a flexible retaining rib, and the valve stem includes an inlet communicating with the water outflow segment, a fixing rib, an opening communicating with the inlet, and a guiding column. The guiding column has a seal ring. The fixing rib retains with the flexible retaining rib so as to limit a rotation of the adjuster along the body. The adjuster includes a threaded orifice screwing with a screwing section of the controller, an inflow aperture fitting with the guiding column, and a shoulder formed beside the inflow aperture. The controller is coupled with a water supply pipe.

摘要： A sprinkler structure contains: an accommodation tube, multiple water outflow zones, multiple grooved partitions, multiple first water gathering zones, and multiple second water gathering zones. Each first water gathering zone has a first inlet, and each second water gathering zone has a second inlet, the accommodation tube includes multiple first guide orifices and multiple second guide orifices. Each first guide orifice communicates with the accommodation tube, and each second guide orifice communicates with the accommodation tube, hence a control bar is rotatably connected and horizontally moves in each first guide orifice and each second guide orifice. The control bar further includes an inflow chamber and a receiving portion for housing a stop element, such that the stop element abuts against each first water gathering zone and each second water gathering zone. The control bar further includes two seal rings, and the accommodation tube further includes an elongated lid.

摘要： A single or dual sided direction-controllable sprinkler comprises two rotatable trigger portions slidably disposed on a main body. When one trigger portion is limited by a fastener, the two trigger portions have the same rotational position, and when the one trigger portion is not limited by the fastener, the rotational positions of the two trigger portions are controlled independently. The fastener is selectively connected to allow the user to selectively control one of the trigger portions or both of the trigger portions together so that various water sprinkling modes are available.

摘要： A water spray gun includes a main body, an operating member and a switch part. The main body includes a handle portion and a tube portion extended from the handle portion and provided with a spray head. A control assembly is enclosed in the main body for control of water outflow and adjustment of the amount of the water outflow. The operating member is pivotally connected to the position where the handle portion meets the tube portion. The switch part is arranged at the operating member and is engaged with the control assembly. The amount of water outflow is controlled by relative movement between the switch part and the operating member.
