Description
Technical Field
[0001] This invention relates to the field of rocker arm nozzle technology, specifically to a rocker arm nozzle with an irregularly shaped spray area. Background Technology
[0002] Currently, the market commonly uses circular spray area rocker arm nozzles. However, since circular or fan-shaped spray areas are not densely tessellated, there are issues such as overlapping spray areas and terrain mismatch during the spraying process, leading to overspraying and missed spraying. This is especially problematic in green gardens with planned roads, where water splashes exceeding the spray area can affect pedestrian traffic and cause inconvenience.
[0003] In addition, other methods can cover irregular spray areas by changing the nozzle pitch angle, water volume, or water pressure. However, these methods generally have the disadvantage of being highly specific and can only be adapted to spray areas of a certain fixed shape, such as square or elliptical spray areas. They cannot adapt to the needs of different sites, have low economic value, and are difficult to promote. Therefore, this invention proposes a rocker arm nozzle for irregular spray areas.

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figure 1-3 A rocker arm nozzle for an irregularly shaped spray area includes a mounting assembly, an elevation adjustment assembly on the surface of the mounting assembly, and a nozzle assembly on top of the elevation adjustment assembly.
[0023] The mounting assembly includes a lower tube 1, a mounting base 2 is fixedly mounted on the bottom of the lower tube 1, and fixing bolts 3 are threaded around the surface of the mounting base 2. A water inlet connector 4 is fixedly mounted on the surface of the lower tube 1 and at one end near the mounting base 2, and a water inlet pipe 5 is threaded inside the water inlet connector 4.
[0024] The elevation angle adjustment assembly includes an angle adjustment ball 6 fixedly installed on the surface of the lower tube 1. The side surface of the angle adjustment ball 6 has vertical slide rail slots 61, with at least 30 slots of equal spacing. The two ends of each slide rail slot 61 contact the top and bottom walls of the angle adjustment ball 6, respectively. A sliding block 25 is movably mounted on the outer surface of the angle adjustment ball 6. A connecting rod 26 extending into the angle adjustment ball 6 is fixedly mounted on the inner side of the sliding block 25. A track ball 27 is fixedly mounted on the end of the connecting rod 26 away from the sliding block 25. The surface of the connecting rod 26 is movably mounted... A spring plate 28 is installed that contacts the inner wall of the angle adjustment ball 6. The elasticity of the spring plate 28 allows the sliding block 25 to be tightly attached to the outer surface of the angle adjustment ball 6. A docking rod 9 is movably installed on the top of the lower tube 1. A connecting shaft 10 is movably installed on the outer surface of the docking rod 9. An upper tube 11 is movably installed inside the docking rod 9. A crossbar 22 is fixedly installed on the side surface of the bottom end of the upper tube 11. A sliding rail 23 is fixedly installed at the end of the crossbar 29 away from the docking rod 10. The spray angle of the nozzle assembly is changed by sliding on each track ball 27 through the sliding rail 23.
[0025] The nozzle assembly includes a docking seat 14 fixedly mounted on the top of the upper tube 11, a swing nozzle 15 fixedly mounted on the surface of the docking seat 14, a top seat 16 fixedly mounted on the top of the docking seat 14, a central shaft 17 fixedly mounted on the top of the top seat 16, a rotating frame 18 fixedly mounted on the surface of the central shaft 17, a torsion spring 19 fixedly mounted on the inner top wall of the rotating frame 18, a rocker arm 20 movably connected to the central shaft 17 fixedly mounted on the bottom of the torsion spring 19, and a striking block 21 fixedly mounted on the bottom of the rocker arm 20.
[0026] In this embodiment, the top and bottom of the angle adjustment ball 6 are both flat, the bottom surface of the angle adjustment ball 6 is circular, and a support plate 7 fixedly connected to the lower tube 1 is fixedly installed at the bottom of the angle adjustment ball 6. The top of the angle adjustment ball 6 has an opening 8, and the inner wall of the angle adjustment ball 6 has a transverse wave pattern, which can effectively reduce the probability of the spring plate 28 automatically sliding on the inner wall of the angle adjustment ball 6. The opening 8 is circular, and the diameter of the opening 8 is equal to the diameter of the bottom surface of the angle adjustment ball 6. The diameter of the opening 8 is between 20-30 cm. The upper tube 11 is located at the center of the opening 8, and the opening 8 allows the upper tube 11 to have room to swing.
[0027] In this embodiment, the side surface of the angle adjusting ball 6 is provided with vertical slide rail slots 61. There are 30 slide rail slots 61, and the spacing between the slide rail slots 61 is equal. The length of the slide rail slots 61 is 5 cm shorter than the side wall length of the angle adjusting ball 6. The connecting rod 26 is located inside the slide rail slots 61. The sliding block 25 is slidably connected to the angle adjusting ball 6 through the connecting rod 26. The connecting rod 26 is cylindrical. The number of sliding blocks 25 is equal to the number of slide rail slots 61. The sliding track 23 is slidably connected to the track ball 27. The operator can change the position of each sliding block 25 in the actual site so that all the track balls 27 are connected to form a curved track, thereby changing the spray angle of the nozzle assembly.
[0028] In this embodiment, the side view shape of the sliding track 23 is a semi-circular ring. Both ends of the sliding track 23 are fixedly installed with flared tubes. The opening of the flared tubes is larger than the inner diameter of the sliding track 23, so as to facilitate the sliding track 23 to slide on the track ball 27. The surface of the sliding track 23 is fixedly installed with reinforcing hoops 24. The reinforcing hoops 24 are semi-circular rings. The number of reinforcing hoops 24 is between 10 and 20. The reinforcing hoops 24 make the sliding track 23 more robust.
[0029] In this embodiment, the lower tube 1 is rotatably connected to the docking rod 9, and the docking rod 9 is rotatably connected to the upper tube 11 via the connecting shaft 10. The docking rod 9 has a cavity inside that communicates with the lower tube 1. Side connectors 12 are fixedly installed on the right side of the docking rod 9 and the right side of the upper tube 11. A hose 13 is fixedly connected between the two side connectors 12. The length of the hose 13 is greater than the distance between the lower tube 1 and the upper tube 11. The side connector 12 on the right side of the docking rod 9 communicates with the cavity inside the docking rod 9. A sealing ring that is rotatably connected to the docking rod 9 is fixedly installed on the inner wall of the lower tube 1. The sealing ring reduces water overflow from the lower tube 1. The connection between the crossbar 22 and the upper tube 11 is located at the center of the angle adjustment ball 6. A sealing plug is fixedly installed inside the upper tube 11. The sealing plug is located below the side connector 12 on the right side of the upper tube 11.
[0030] During operation, the rocker arm 20 strikes the nozzle assembly, which in turn drives the crossbar 22 to rotate. The sliding rail 23 connected to the crossbar 22 slides on the variable track. When the variable track curve goes up, the elevation angle of the crossbar 22 increases, and the elevation angle of the nozzle assembly increases accordingly, thus increasing the spraying distance. When the variable track curve goes down, the elevation angle of the crossbar 22 decreases, and the elevation angle of the nozzle assembly decreases accordingly, thus decreasing the spraying distance. When the nozzle assembly makes a circular motion, the spraying distance can be controlled at both near and far distances within the set variable track, thus achieving full coverage of the irregular spray area.
[0031] In this embodiment, when the crossbar 22 moves to the lowest point of the angle adjustment ball 6, the elevation angle of the spray assembly is 45 degrees, at which point the water spray range is the longest. When the crossbar moves upward from the lowest point of the angle adjustment ball 6, the elevation angle of the nozzle assembly gradually increases, and the water spray range gradually decreases, thereby maximizing the utilization of the angle adjustment ball 6.
[0032] Working principle: The traditional rocker arm nozzle is divided into upper and lower sections. The upper section mainly consists of the upper pipe 11 and the nozzle assembly at the top of the upper pipe 11. The lower section mainly consists of the angle adjustment ball 6 and the lower pipe 1. The angle adjustment ball 6 has several sliding rail slots 61 on its surface, and a sliding block 25 is slidably installed in each sliding rail slot 61. The sliding block 25 is connected to the track ball 27 through the connecting rod 26. All the track balls 27 form a variable track. The upper pipe 11 is connected to the sliding track 23 through the crossbar 22, and the sliding track 23 is fitted onto the track ball 27. The water flow in the lower pipe 1 passes through the connecting rod 9 and the hose 13 to connect it to the upper pipe 11. In addition, the upper pipe 11... By rotating the connecting shaft 10 and the docking rod 9, the upper tube 11 can change its pitch angle based on the lower tube 1 through the connecting shaft 10. With the help of the striking force of the rocker arm 20, the sliding track 23 slides laterally on several track balls 27. When the variable track curve goes up, the pitch angle of the crossbar 22 increases, the pitch angle of the nozzle assembly increases accordingly, and the spraying distance increases accordingly. When the variable track curve goes down, the pitch angle of the crossbar 22 decreases, the pitch angle of the nozzle assembly decreases accordingly, and the spraying distance decreases accordingly. When the nozzle assembly makes a circular motion, the spraying distance can be controlled at both near and far distances within the set variable track, that is, to achieve full coverage of the irregular spray area.
