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.

Abstract: A control valve assembly for spray guns comprises a flexible valve having a water-sealing portion defined by a support surface and an abutment surface conjoined to a pivoting rod via a water-stop surface disposed there-between. A water-pressure adjusting valve includes a pressure-relief section having a flow orifice to mount to a valve shaft of a pressure valve and match to the pivoting rod and the abutment surface of the flexible valve thereby. The pressure-relief section, precisely situated between a stop seat of a spray gun body and a valve seat, has a watertight ring fixed at one side to closely abut against the stop seat. A support section, extending at the other side of the water-pressure adjusting valve, has a pivoting hole defining the end portion opposite to the flow orifice thereof. Besides, the pressure valve has a positioning ring mounted to the predetermined position of the valve shaft thereon.

Abstract: A control valve assembly structure for spray guns comprises a pistol body made up of water inlet and outlet conduits in fluid communication with a valve chamber having a control valve assembly mounted therein wherein the water inlet and outlet conduits and the valve chamber are respectively equipped with a first aperture, a second aperture, and a third aperture having a narrowed opening to form a stop seat for the abutting location of an end cover. The end cover has a receiving section and an actuating groove disposed therein for the accommodation of a valve seat and a spring element respectively, permitting a valve sleeve and a plunger flexibly pushed by the spring element to abut tight against a flexible valve whose water-sealing portion is stretched to tightly seal off the third aperture thereby, facilitating an even application of force thereon as well as an easier and economical processing thereof.
