The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.

Abstract: A sprayer includes a nozzle that includes a panel, an operation chamber and an outlet element. The outlet element includes an external tube, internal tubes and outlets. The external tube extends in the operation chamber from the panel. The internal tubes extend in the external tube from the panel. Each internal tube includes tangential passageways. The outlets are made in the panel, in communication with the internal tubes. The distributor is inserted in the operation chamber and includes a disc and an inlet element. The inlet element includes a cylinder, inlets and protuberances. The cylinder extends into the external tube from the disc. The inlets are made in the cylinder. Interior of the cylinder is in communication with exterior of the cylinder via the inlets. The protuberances are formed on the cylinder and inserted in the internal tubes. The barrel includes a water supply tube connected to the inlet element.

Abstract: An anti-twist water-saving permeable hose is provided. A wall of the permeable hose has two curved support portions and two permeable portions connected between the two support portions. The permeable portions are mated with the support portions to form a flat chamber. The permeable portions have a curvature greater than that of the support portions. The support portions have a hardness value greater than that of the permeable portions, so that the support portions and the permeable portions are still able to cooperate with each other to form the chamber when the permeable hose is bent. Thus, the permeable hose does not twist to ensure its service life.

Abstract: A protective cover structure of a water hose includes a water hose connector, a rigid protective cover, and at least one sealing member. The water hose connector has elasticity. A front end of the water hose connector is formed with a mating portion for connecting with a spray nozzle. A rear end of the water hose connector is formed with a concave step and a connecting portion. A rear end of the metallic press member is inserted into the water hose. A front end of the metallic press member is formed with a mating cap having an evaginated rim. The concave step of the water hose connector is movably mated with the metallic press member through the evaginated rim of the mating cap, such that the spray nozzle can be turned at will relative to the water hose and won't be turned reversely, twisted, bent.

Abstract: A spray structure of a water spray gun is formed on a surface cover of the water spray gun. The surface cover is formed with a plurality of spray orifices. The inner side of the surface cover is formed with annular flanges each corresponding to the edge of each spray orifice. Each flange is formed with a tangential opening. The surface cover of the present invention is formed with the tangential opening instead of the inclined opening of the water distribution member of the prior art. When the water flows to the tangential opening and then enters the flange to be rotated and sprayed out through the spray orifices. The tangential opening of the present invention is flat and smooth and won't be blocked. The water spray gun won't be damaged easily and has a long service life. The cost is reduced.

Abstract: A cover structure of sprinkler guns comprises a body mounted on a gun body and a netting mounted on the body. The body comprises a non-netted water spout formed thereon. The netting comprises a netted water spout formed thereon. The netting is detachably mounted on the body. A sealing ring is disposed between the netting and the body. When pores of the netted water spout are clogged, the user can detach the netting directly to wash the dirt off from the opposite side of the netting or substitute the new netting for the old one without replacing a whole cover, thereby cleaning the cover conveniently and decreasing the cost of the use.

Abstract: A printing structure of a water pipe contains a body having a plastic layer formed around an outer rim of the body and a printing layer integrally formed with and around the plastic layer, wherein the printing layer has a color pattern or a graphic pattern transfer printed thereon. The printing water pipe has a variety of patterns on the body thereof so as to provide pattern options to the customer. In addition, the pattern on the body of the water pipe allows being printed based on the users' requirement, thus obtaining customization.

Abstract: A switch handle at a bottom section of a sprayer long tube of a water sprayer includes a sprayer long tube, a switch and an inlet tube having a connecting sleeve pivotally connected to a bottom end thereof. The bottom section of the long tube is connected to an outlet section of the switch. The inlet section of the switch is connected to the inlet tube. The sprayer long tube, switch and inlet tube are integrally connected. The connecting section of bottom section of the long tube and the switch, the periphery of the switch, the connecting section of the switch and the tube, and the entire peripheral surface of the tube are injection molded integrally from plastics (rubber) one or two times, to thereby effectively couple them integrally such that the plastic (rubber) injection molded parts is suitable to be used by the handle provided at the bottom section of the sprayer long tube.

Abstract: A retaining supporter of a rotary sprinkler is disclosed. The retaining supporter has a cruciform cylindrical base at the lower half of the rotary sprinkler. Two plates with equal length are crossed with each other so as to form a cylindrical member with a cruciform cross section. The width of one plate is thicker than the other one, and the vertical surface of the wider plate is a curved surface and has a shape like an inverted triangle. When the lower half section of the fixing supporting element in inserted into the soil, it can be inserted easily. When the top section of the rotary sprinkler is connected with water pipe for water flow, the water flows through the interior of the fixing supporting element of the rotary sprinkler, so that water can be sprayed from the water outlet of the rotary sprinkler and moves the rotary sprinkler.

Abstract: A spout plate used in a spray head of a sprayer includes a spout plate insertably secured at the spout end of the spray head and made from a slightly flexible rubber or plastic material such that multiple posts defining distinct water guide channels are provided annularly on the spout surface thereof. A center of the spout plate is connected to a center of the interior of the spray head. When the spout plate is insertably secured at the spout end of the front end of the spray head of the sprayer, and water flows through the interior of the spray head and flow out of the spout plate for spraying via the water guide channels of the posts provided on the spout plate, different water jets can be sprayed out from the water guide channels of the posts to thereby provide an extensive spraying area and multiple effects.
