Description

Technical Field

[0001] This utility model relates to the field of sprayers, specifically to a water sprinkler. Background Technology

[0002] A sprinkler is a highly efficient water-saving irrigation device. Its core mechanical structure uses an internal turbine and gear set to convert the kinetic energy of water into the smooth rotational force of the nozzle. The entire system requires no external electricity, driven solely by water pressure, to achieve uniform, automated, wide-area spraying. It combines functionality and durability. Sprinklers specifically designed for landscaping typically consist of a nozzle base, rotating mechanism, and nozzles made of high-strength engineering plastics or metal. The core of the drive lies in its internal turbine, gear set, and reversing mechanism: water flow impacts the turbine to generate power, which is then reduced and transmitted torque through a precision gear set, driving the nozzle to rotate at a uniform speed. In-ground rotary sprinklers employ a telescopic design; water pressure lifts the valve core, causing the nozzle to pop out, and when water flow stops, it automatically retracts under spring pressure, effectively preventing damage from obstacles. This mechanical system requires no electricity, achieving stable, uniform, fully automatic rotary spraying solely with water pressure.

[0003] A search revealed that patent number CN202322967388 discloses a sprayer with adjustable nozzle angle, including a rocker base with a water inlet chamber. Multiple flexible nozzles communicating with the water inlet chamber are arranged on the upper side of the rocker base. An adjustment mechanism for adjusting the spray angle of the flexible nozzles is also provided on the upper side of the rocker base. The adjustment mechanism includes a sliding plate and an adjusting rod. The sliding plate is laterally slidable on the upper side of the rocker base and has adjustment holes. The flexible nozzles pass through the corresponding adjustment holes. The adjusting rod rotates with the rocker base and is equipped with an adjusting wheel. The sliding plate has an adjusting rack that meshes with the adjusting wheel. The spray direction of the flexible nozzles can be adjusted through the adjustment mechanism. This design achieves adjustment only through the cooperation of the adjusting rod, adjusting wheel, and sliding plate, resulting in a simple structure, small space occupation, and thus a reduced overall size of the sprayer. Operation is convenient; the sliding plate can be adjusted laterally by rotating the adjusting rod via the adjusting wheel. Its drawback is that the structure is too complex, and there is still room for simplification while maintaining the original function. Summary of the Invention

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 5 A sprinkler includes a water inlet cylinder assembly 1, with an external water inlet 33 at its bottom and rotatably fixed to a swing base 3 on both sides; the swing base 3 has a water inlet chamber 4, with water inlet holes 2 on its lower side; a top cover 6 is fixed to the top of the swing base 3 by ultrasonic welding, and multiple water outlet holes 7 are distributed on the top cover 6. In this embodiment, the water outlet holes 7 are divided into two rows, with each row of outlet holes 7 evenly spaced and facing at different angles, ensuring that the water flow is evenly sprayed in different directions.

[0022] The water inlet assembly 1 includes a water inlet base 8 and a water inlet cover 9. The water inlet base 8 and the water inlet cover 9 are interlocked to form an installation cavity 10. A rotating cylinder 11 and a first adjusting ring 12 and a second adjusting ring 13 are respectively installed in the installation cavity 10. One end of the water inlet cover 9 is provided with a through hole 14. The bottom of the water inlet cover 9 is provided with a fixing buckle 15, and the bottom of the corresponding water inlet base 8 is provided with a fixing groove 16, so that they are fixed by snapping after insertion. T-shaped retaining strips 19 are provided on both sides of the inner wall of the water inlet base 8, and retaining grooves 20 are provided on both sides of the inner wall of the corresponding water inlet cover 9, so that they are positioned by sliding snapping. The bottom of the water inlet base 8 is provided with an L-shaped water pipe 28, so that the outer water inlet 33 is connected to the outer water outlet 29 on the inner wall of the water inlet base 8. The outlet 29 is connected to the inner inlet 17 of the rotating drum 11. The other end of the rotating drum 11 is provided with an inner outlet 21, which passes through the through hole 14 on the water inlet cover 9 and is connected to the water inlet 2 at the bottom of the rocking seat 3 to realize water passage connection.

[0023] The rotating drum 11 has a transmission assembly inside. A gear ring 18 is provided on the outer wall of the outlet 29. A first adjusting ring 12 and a second adjusting ring 13 are fitted onto the gear ring 18. Both the first adjusting ring 12 and the second adjusting ring 13 have internal hollowed-out sections with limiting plates 31 and positioning elastic teeth 34. The positioning elastic teeth 34 are formed by the inner rings 35 of the first adjusting ring 12 and the second adjusting ring 13 protruding inwards 36, with toothed structures formed on the protrusions 36, facilitating positioning and engagement with the teeth on the gear ring 18. The limiting plates 31 are arranged on the first adjusting ring 12 and... On the left and right symmetrical positions of the second adjusting ring 13, the limiting plate 31 is L-shaped. Typically, the limiting plate of the first adjusting ring 12 is arranged on one side, and the limiting plate of the second adjusting ring 13 is arranged on the other side. Thus, by rotating and adjusting the first adjusting ring 12 and the second adjusting ring 13, the relative positions of the left and right limiting plates 31 can be adjusted, thereby controlling the left and right swing amplitude of the rotating drum 11. A swing rod 30 is provided on one side of the inner inlet 17 of the rotating drum 11. The swing rod 30 can swing and abut against the limiting plate 31 to limit the rotation. The cylinder 11 has a forward and reverse rotation function. A push rod 32 is located below the swing arm 30. The swing arm 30 and push rod 32 cooperate with the limiting plates 31 on the first adjusting ring 12 and the second adjusting ring 13. When the push rod 32 rotates to the limit position where it is aligned with the limiting plate 31 of the first adjusting ring 12, the limiting plate 31 of the first adjusting ring 12 pushes the swing arm 30 to swing. This causes the blocking part on the other end of the swing arm 30 to block one side of the water inlet of the transmission assembly while opening the other side. Thus, due to the change in water flow direction, the transmission assembly... When the push rod 32 rotates in the opposite direction, the rotating drum 11 also rotates in the opposite direction until the push rod 32 rotates to the position of the limiting piece 31 of the second adjusting ring 13. At this point, the limiting piece 31 of the second adjusting ring 12 will push the swing rod 30 to swing in the opposite direction again, so that the blocking part on the other end of the swing rod 30 blocks the water inlet hole on the other side of the transmission component, while opening the water inlet hole on this side. In this way, because the water flow direction changes, the transmission component rotates in the forward direction again, so that the transmission component rotates back and forth. The transmission component is a conventional design. Please refer to Chinese Patent No. 201921337096.5 for a sprinkler transmission structure that realizes oil-water separation. The rotating drum 11 is also set on the transmission component, so it can also swing back and forth.

[0024] The outer wall of the water inlet base 8 is provided with a mounting groove 22, and a fixing plate 23 is fixed on the mounting groove 22. A drive ring 27 is sleeved on the inner side of the fixing plate 23. A transmission rack 5 is provided on the outer wall of the drive ring 27, which meshes with the inner ring teeth 37 of the water inlet base 8. The drive ring 27 and one end of the inner water inlet of the rotating drum 11 are snapped together. The outer walls of the swing base 3 and the fixing plate 23 are respectively provided with fixing buckles 24 and fixing posts 25. There is also a connecting plate 26. The upper part of the connecting plate 26 has a locking hole, which is connected to the fixing buckle 24 of the swing base 3. The lower part of the connecting plate 26 has a rotating hole, which is rotatably connected to the fixing post 25 on the fixing plate 23 to achieve the fixing function.

[0025] When installing this utility model, the worker first puts the drive ring 27 on the inner side of the fixing plate 23, then installs the fixing plate 23 onto the mounting groove 22 of the water inlet base 8, then puts the first adjusting ring 12 and the second adjusting ring 13 onto the toothed ring 18 respectively, then snaps one end of the inner water inlet 17 of the rotating drum 11 and the drive ring 27 together, passes the through hole 14 of the water inlet cover 9 through the inner water outlet 21, and pushes the retaining strip 19 along the retaining groove 20, and fixes the retaining buckle 15 and the retaining groove 16 together. The upper cover 6 and the swing base 3 are ultrasonically welded into a whole, and the water inlet hole 2 at the bottom of the swing base 3 is inserted and fixedly connected to the inner water outlet 21. Thus, the water path is fully connected, so that the water can be evenly sprayed out from the water outlet 7.
