Abstract: A sprinkler comprises a water outlet tube and an annular adjusting element. The water outlet tube comprises a positioning and stopping portion and a mounting section with a position-limiting guide block. The position-limiting guide block comprises a water outlet opening communicating with the interior of the water outlet tube. The adjusting element comprises a pivot hole that allows the adjusting element to rotate about and along the mounting section. The pivot hole comprises a position-limiting space for accommodating the position-limiting guide block in a pivotable manner, in order for the position-limiting guide block to limit back-and-forth rotation of the adjusting element. The position-limiting space comprises a through hole and a water-blocking area. The adjusting element can be rotated in one direction to align the through hole with the water outlet opening and in the opposite direction to block the water outlet opening with the water-blocking area.

Abstract: A water spray gun with flow control comprises a gun body having a water inlet, a water outlet and an accommodating chamber connected therebetween; a water control valve, being pivotably installed in the accommodating chamber and having a receiving recess being received in the accommodating chamber, wherein the receiving recess has its outside formed with an opening and has its bottom provided with a water-filling port; and a sealing block slidably installed in the receiving recess, so that when a pressure of water coming from the water-filling port acts on the sealing block from bottom, the sealing block slides toward the opening. Thereby, water pressure ensures close fit of the sealing block. Even if the sealing block is worn, the water pressure coming from the water-filling port can still push the sealing block outside to keep the water outlet sealed.

Abstract: An improved sprinkler structure provides a fastener of a positioning ring for elastically fastening a water guiding pipe. A fastening dot of the positioning ring can engage with a tooth of a water inlet connector effectively so that the water guiding pipe does not detach easily. Water outlet direction of a first water passage and a second water passage is tangent with an impeller; therefore, when water is let out, the water pressure will push the impeller evenly to make the sprinkler to rotate evenly and smoothly. A push rod of a water inlet switching device is pivotally connected with a connecting rod. When the connecting rod is pushed, because a clearance is present between the connecting rod and a connecting groove, the force received by the connecting rod is partially converted into momentum of displacement when the push rod wiggles.

Abstract: A gardening gun structure may include a water gun body with an extended handle; a pull grip pivotally connected to a rear side of the handle; and a water controlling shaft set comprising a water controlling shaft, a water stoppage ring and a water controlling head being disposed at an end of the water controlling shaft, and a screw thread section being disposed at another end, a spring being sleeved around a shaft section disposed at an inner end of the water controlling head, a water stoppage pad with a central hole being sleeved around a shaft section disposed at a rear end of the spring, a first bush being sleeved around a shaft section between the spring and the water stoppage pad, and a second bush being sleeved around a shaft section disposed at a rear end of the water stoppage pad.

Abstract: A grip structure of water sprayer comprises a sprayer body, a grip body is extended downward from one end of the sprayer body, a front surface of the grip body is covered with a front grip fitting portion, a fixing structure is disposed on a back surface of the grip body, a back grip fitting portion is fitted on the back surface of the grip body. The back grip fitting portion has a fitting structure to be fitted and engaged with the fixing structure, so that the back grip fitting portion is fitted on the grip body. Accordingly, the back grip fitting portion of the present invention can be dismounted and replaced at will which is convenient for maintenance and usage.

Abstract: A sprinkler structure includes a shell base, a water nozzle, a plurality of spiracles, a water conveyance element, an eccentric gear device, a drive gear device, and a fixing base. The eccentric gear device performs an eccentric movement in responding to an external force, and drives the water conveyance element to perform a reciprocating pivotal turning action. The drive gear device is disposed inside the shell base and is coupled to the eccentric gear device. The drive gear device is driven by the water current to rotate, so that the eccentric gear device drives the water conveyance element to perform the reciprocating pivotal turning action. The water nozzle is driven by the reciprocating pivotal turning action to change the angle of the water outlet surface continuously within an angle range. The fixing base is connected to the water nozzle and the shell base.
