Description

Technical Field

[0001] This invention relates to the field of sprinkler technology, specifically to a sprinkler with adjustable nozzles. Background Technology

[0002] Adjustable nozzle angle sprinklers are a modern type of garden irrigation equipment that allows for flexible adjustment of the spray angle, optimizing water distribution and utilization efficiency. These sprinklers typically consist of a robust plastic or metal body with a built-in small water pump and nozzle system. Users can easily change the spray angle by rotating or turning the adjustment knob or button around the nozzle, enabling coverage of various areas from narrow to wide. The main advantage of this type of sprinkler lies in its high adaptability and flexibility. Whether in lawns, flower beds, or vegetable gardens, users can adjust the sprinkler angle according to the specific plant layout and soil moisture requirements, ensuring that every plant receives adequate water. Adjustable nozzle angle sprinklers are particularly effective at saving water. By precisely controlling the spray angle, they minimize water evaporation and loss, improving irrigation efficiency. Furthermore, these sprinklers usually feature a splash guard design, ensuring more even water distribution across the target area rather than causing excessive water accumulation or runoff on the surface.

[0003] Currently, swing pipes sold and used on the market typically use vertical pushing or parallel pulling of inclined blocks to drive a sliding plate to force the flexible nozzle to reset and control the spray angle. This driving structure is laborious to operate, especially when controlling the tilt of the flexible nozzle, it often cannot have sufficient locking force, so it is easy to cause the flexible nozzle to rebound, which in turn leads to the failure of the swing pipe's spray angle adjustment. Therefore, it does not meet the existing needs, so we propose a nozzle adjustable sprinkler. Summary of the Invention

Whether for large lawns, trees, or small flower beds, it achieves optimal irrigation results. This solves the problem mentioned in the background art where insufficient locking force is often lacking when controlling the tilt of the flexible nozzle, easily causing the flexible nozzle to rebound and leading to the failure of the spray angle adjustment of the swing tube.

[0010] As an optional solution of the nozzle adjustable sprinkler of the present invention, wherein: the two pins are respectively engaged with the two sides of the fixing block, the two sides of the pins are connected with the locking blocks, the sides of the fixing block are respectively provided with locking grooves, and the locking blocks are slidably engaged with the locking grooves.

[0011] As an optional solution of the nozzle adjustable sprinkler of the present invention, the fixed block has a track groove on its side, the swing plate has locking columns connected to both sides, the locking columns are slidably engaged with the track groove, the fixed block has a toothed block at its bottom, the mounting base has a toothed plate on its side, and the toothed block is slidably engaged with the toothed plate.

[0012] As an optional solution of the nozzle adjustable sprinkler of the present invention, the mounting cover is provided with a locking ring on the outside, the end of the locking ring is connected to a support column, the other end of the support column is connected to a support frame, the support frame has a cavity inside, and a limit block is provided inside the cavity.

[0013] As an optional solution for the nozzle-adjustable sprinkler of the present invention, the limiting block has a first air groove on its side, the support frame has a second air groove on its side, and an air pipe is also provided inside the cavity. One end of the air pipe is connected to the end of the first air groove, and the other end of the air pipe is connected to the end of the second air groove. A compression ball is connected to the end of the second air groove. The compression ball is in contact with the pin, and the air pipe connects the cavity and the compression ball.

[0014] As an optional embodiment of the adjustable nozzle sprinkler of the present invention, wherein: a piston disc is connected inside the cavity, a movable groove is provided at the end of the support frame, a movable plate is connected to the side of the piston disc, the movable plate passes through the interior of the movable groove, a movable block is connected to the side of the movable plate, a fixed shaft is connected to the side of the support frame, and the movable block is slidably connected to the side of the fixed shaft.

[0015] As an optional solution for the nozzle-adjustable sprinkler of the present invention, the automated component includes a turntable and a rotating rod. The turntable is connected to the side of the fixed frame, and a central shaft is connected to the middle of the turntable. The central shaft passes through the side of the fixed frame. A servo motor is installed on the other side of the fixed frame, and the output shaft of the servo motor is keyed to the central shaft. One end of the rotating rod is rotatably connected to the side of the turntable, and the other end of the rotating rod is connected to the bottom of the moving block.

[0016] The present invention has the following beneficial effects:

[0017] 1. This adjustable nozzle sprinkler, through its drive mechanism, allows for nozzle pipe adjustment. Pushing the pin causes the fixing block to slide inside the mounting cover, resulting in the locking pin sliding up and down within the track groove. This, in turn, moves the swing plate up and down, causing the nozzle pipe on the side of the swing plate to move accordingly, thus spraying water. The independent adjustment mechanism allows the nozzle pipe to be adjusted to different angles, avoiding a single watering mode. Whether it's a large lawn, trees, or a small flower bed, it achieves optimal irrigation results. This solves the problem of insufficient locking force when controlling the tilt of flexible nozzles, which often causes nozzle rebound and leads to the failure of the swing pipe's spray angle adjustment.

[0018] 2. This adjustable nozzle sprinkler incorporates an automated component. This component works in conjunction with the drive mechanism to activate the servo motor. The servo motor drives the turntable to rotate. As the turntable rotates, it causes the rotating rod and the moving block on the side of the rotating rod to slide on the side of the fixed shaft. This causes the moving block to drive the piston disc to slide inside the cavity, pushing the gas inside the cavity to the first air groove and then flowing from the second air groove to the extrusion ball. The extrusion ball extrudes and pushes the pin. This automated adjustment method also reduces the intensity of manual operation, lowers the frequency of maintenance and upkeep, and further reduces operating costs.

[0019] 3. This adjustable sprinkler nozzle utilizes a toothed block design. The toothed block engages with the toothed plate, and as the pin is pushed, the toothed block at the bottom of the fixing block slides and meshes with the toothed plate inside the mounting housing. When adjusted to the desired angle, the toothed block and toothed plate engage, preventing misalignment. This meshing design not only provides sufficient limits but also enhances the reliability and stability during angle adjustment. Once the desired angle is reached, the toothed block and toothed plate are tightly engaged, ensuring the nozzle tube is securely fixed in any position, preventing misalignment and angle changes caused by external pressure, thus improving the overall design.

Detailed Implementation

[0029] 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.

[0030] Example 1: This example aims to address the problem of laborious operation in commercially available swing tubes that typically use vertical pushing or parallel pulling of inclined blocks to drive a sliding plate to forcibly reset the flexible nozzle and control the spray angle. Please refer to [link to relevant documentation]. Figure 1-8An adjustable nozzle sprinkler includes a mounting base 110 and a mounting cover 160. The mounting cover 160 is positioned above the mounting base 110. A water inlet pipe head 220 is provided at one end of the mounting cover 160 and the mounting base 110, and a connecting cover 221 is provided at the other end of the mounting cover 160 and the mounting base 110. A plurality of nozzle pipes 162 for spraying water are provided between the mounting base 110 and the mounting cover 160. A drive mechanism 150 is provided at both ends of the mounting cover 160, and an automation component 210 is provided at the end of the mounting cover 160. The automation component 210 works in conjunction with the drive mechanism 150.

[0031] The mounting cover 160 has connecting slots 170 on both sides. The drive mechanism 150 includes a fixing block 151 and a pin 152. The fixing block 151 is located inside the mounting shell. There are two pins 152, which are inserted into the connecting slots 170 respectively.

[0032] See Figure 2 The water inlet pipe head 220 and the connecting cover 221 are respectively threaded to the two ends of the mounting base 110 and the mounting cover 160. A rotating assembly 130 is also provided between the mounting base 110 and the mounting cover 160. The rotating assembly 130 includes a locking base plate 131 installed at the end of the mounting base 110 and a swinging locking plate 132 provided above the locking base plate 131. The rotating assembly 130 also includes a nozzle plate 153 provided between the locking base plate 131 and the swinging locking plate 132.

[0033] The mounting base 110 has threaded rings connected to both ends, and the water inlet pipe connector and the connecting cover 221 are threaded to the side of the threaded rings.

[0034] The inlet pipe head 220 and the connecting cap 221 are securely fixed to the two ends of the mounting base 110 and the mounting cap 160 via a threaded connection, ensuring stable water flow. Meanwhile, the rotating assembly 130 between the mounting base 110 and the mounting cap 160 allows for flexible adjustment of the nozzle pipe 162 angle to meet irrigation needs.

[0035] The water cavity 111 is connected to the water inlet pipe head 220. The side of the locking base plate 131 is provided with several first nozzle holes 154. There are two swing plates 132. The two swing plates 132 are respectively mounted with a rotating shaft 155 at one end away from the water inlet pipe head 220 and the connecting cover 221. The rotating shaft 155 is hinged to the side of the mounting cover 160. The surface of the swing plate 132 is provided with a second nozzle hole 164. The nozzle tube 162 is connected to the surface of the nozzle plate 153.

[0036] The mounting base 110 has a water cavity 111 inside. The mounting base 110, the locking base plate 131, the nozzle plate 153 and the nozzle pipe 162 are combined to form a partially sealed water cavity 111, so that water can only flow out from the nozzle pipe 162.

[0037] The pivot 155, which is inserted into the side of the swing plate 132, is connected to the inner wall of the mounting cover 160, allowing the swing plate 132 to rotate flexibly and achieve precise adjustment of the nozzle tube 162 angle. This design not only improves the flexibility of spraying but also avoids the problems of localized over-wetting or over-drying.

[0038] The water cavity 111 inside the mounting base 110, together with the locking base plate 131, nozzle plate 153, and nozzle pipe 162, forms a partially sealed water cavity 111, allowing water to flow only from the nozzle pipe 162. This sealed design ensures efficient water flow management, avoids water leakage and waste, and improves water resource utilization efficiency.

[0039] The surface of the swing plate 132 is connected to several corrugated tubes 163. The nozzle tube 162 is connected to the end of the corrugated tube 163. The corrugated tube 163 is connected to the first nozzle hole 154. The nozzle tube 162 is used in conjunction with the corrugated tube 163. The end of the mounting cover 160 is provided with a third nozzle hole 165. The nozzle tube 162 passes through the interior of the second nozzle hole 164 and the third nozzle hole 165, and extends to the outside of the third nozzle hole 165. The diameter of the third nozzle hole 165 is set to be an opening that gradually expands outward from the center.

[0040] The bellows 163 is a rubber bellows 163. The side of the bellows 163 is fixedly connected to the inside of the second nozzle hole 164. When the swing plate 132 slides up and down, it drives the bellows 163 to compress and expand, and at the same time plays a sealing role. The diameter of the third nozzle hole 165 is set to be a hole that gradually expands outward from the center. The nozzle tube 162 can move flexibly in the third nozzle hole 165.

[0041] Two pins 152 are respectively engaged on both sides of the fixing block 151. The pins 152 are connected to the two sides of the fixing block 151, and the fixing block 151 is provided with slots 172 on the side. The slots 171 and slots 172 are slidably engaged.

[0042] The fixed block 151 has a track groove 173 on its side, and the swing plate 132 has locking posts 174 connected to both sides, which slidably engage with the track groove 173. The drive mechanism 150 can slide inside the through groove.

[0043] During operation, the pin 152 is manually pushed, and the pin 152 causes the fixing block 151 to slide inside the mounting cover 160, thereby causing the locking post 174 to slide up and down inside the track groove 173. The track groove 173 is set to be an inclined strip groove, thereby causing the locking post 174 to move up and down, causing the swing plate 132 to move up and down, and the nozzle pipe 162 on the side of the swing plate 132 is driven to move up and down to spray water.

[0044] In this embodiment: With the drive mechanism 150, when the nozzle pipe 162 needs adjustment, the pin 152 is manually pushed. The pin 152 causes the fixing block 151 to slide inside the mounting cover 160, thereby causing the locking post 174 to slide up and down inside the track groove 173. This causes the swing plate 132 to move up and down, and the nozzle pipe 162 on the side of the swing plate 132 is moved up and down to spray water. Through an independent adjustment mechanism, the nozzle pipe 162 can be adjusted to different angles, avoiding a single watering mode. Whether it's a large lawn, trees, or a small flower bed, optimal irrigation can be achieved. This solves the problem that when controlling the tilt of the flexible nozzle, there is often insufficient locking force, which easily causes the flexible nozzle to rebound, leading to the failure of the swing pipe's spray angle adjustment.

[0045] Example 2 aims to address the problem of time-consuming and labor-intensive manual adjustments. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1-8 The mounting cover 160 is fitted with a locking ring 176 at one end. The locking ring 176 is connected to a support column 303 on the side. The other end of the support column 303 is connected to a support frame 175. The support frame 175 has a cavity 180 inside. A limit block 181 is provided inside the cavity 180. The support frame 175 is mounted on the side of the mounting cover 160.

[0046] See Figure 8 The limiting block 181 has a first air groove 182 on its side, and the support frame 175 has a second air groove 183 on its side. An air pipe 184 is also installed inside the cavity 180. One end of the air pipe 184 is connected to the end of the first air groove 182, and the other end is connected to the end of the second air groove 183. A compression ball 185 is connected to the end of the second air groove 183. The compression ball 185 is in contact with the pin 152. The air pipe 184 connects the cavity 180 and the compression ball 185, allowing airflow to smoothly enter the compression ball 185 and apply pressure, achieving efficient pneumatic control. This design not only improves the system's flexibility and accuracy but also ensures that every action receives appropriate air pressure control, avoiding problems of insufficient or excessive local air pressure.

[0047] A piston disc 190 is connected inside the cavity 180, and the cavity 180 is configured as a piston chamber. The piston disc 190 and the cavity 180 are slidably engaged. A moving groove 191 is provided at the end of the support frame 175. A moving plate 192 is connected to the side of the piston disc 190. The moving plate 192 passes through the interior of the moving groove 191. A moving block 193 is connected to the side of the moving plate 192. A fixed shaft 194 is connected to the side of the support frame 175. The moving block 193 is slidably connected to the side of the fixed shaft 194.

[0048] When the piston disc 190 is moved, the cavity 180 is not connected to the moving groove 191. The main advantages of this design are its flexibility and sealing. By connecting the piston disc 190 inside the cavity 180 and setting the cavity 180 as a piston chamber, the piston disc 190 slides and engages with the cavity 180, ensuring free sliding of the piston disc 190 within the cavity 180, achieving efficient gas management. The moving groove 191 at the end of the support frame 175, and the moving plate 192 and moving block 193 connected to the side of the piston disc 190, allow for precise control of the flow direction and pressure of gas or liquid during the sliding process of the piston disc 190. The moving plate 192 is inserted inside the moving groove 191, ensuring stable movement of the moving block 193 when it slides along the side of the fixed shaft 194.

[0049] See Figure 6 and Figure 7 The automation component 210 includes a turntable 211 and a rotating rod 212. The turntable 211 is connected to the side of the fixed frame. A central shaft 213 is connected to the middle of the turntable 211. The central shaft 213 passes through the side of the fixed frame. A servo motor 222 is installed on the other side of the fixed frame. The output shaft of the servo motor 222 is keyed to the central shaft 213. One end of the rotating rod 212 is rotatably connected to the side of the turntable 211, and the other end of the rotating rod 212 is connected to the bottom of the moving block 193.

[0050] Since the rotating rod 212 is rotatably connected to the turntable 211 and the moving block 193, when the turntable 211 rotates, the moving rod drives the moving block 193 to slide on the fixed shaft 194, thereby driving the piston disc 190 to move. This design not only improves the flexibility and accuracy of the system, but also ensures that each step of the action can be properly controlled, avoiding the problem of insufficient or excessive local action.

[0051] In this embodiment: Through the setting of the automation component 210, the automation component 210 cooperates with the drive mechanism 150 to start the servo motor 222. The servo motor 222 drives the turntable 211 to rotate. While the turntable 211 rotates, it drives the rotating rod 212 and the moving block 193 on the side of the rotating rod 212 to slide on the side of the fixed shaft 194. This causes the moving block 193 to drive the piston disc 190 to slide inside the cavity 180, pushing the gas inside the cavity 180 to the first gas groove 182 and flowing from the second gas groove 183 to the extrusion ball 185. The extrusion ball 185 extrudes and pushes the pin 152. Due to the increased locking force, the nozzle tube 162 is not easy to loosen during repeated use, reducing the frequent disassembly and maintenance caused by loosening, thereby extending the service life of the nozzle and related components. The automated adjustment method also reduces the intensity of manual operation, reduces the frequency of maintenance and upkeep, and further reduces operating costs.

[0052] Example 3 aims to address the problem of insufficient locking force in the nozzle. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1-8 The bottom of the fixing block 151 is provided with a toothed block 301, and the side of the mounting base 110 is provided with a toothed plate. The toothed block 301 and the toothed plate are slidably engaged. The toothed block 301 and the toothed plate are respectively set as a hard rubber block and a hard rubber plate.

[0053] In this embodiment: The toothed block 301, in conjunction with the toothed plate 302, allows the toothed block 301 at the bottom of the fixing block 151 to engage and slide with the toothed plate inside the mounting base 110 while pushing the pin 152. When adjusted to the desired angle, the toothed block 301 and toothed plate 302 engage, preventing misalignment. This engagement not only provides sufficient limiting but also enhances the reliability and stability during angle adjustment. Once the desired angle is reached, the toothed block 301 and toothed plate 302 are tightly engaged, ensuring the nozzle tube 162 is securely fixed in any position, preventing misalignment and angle changes caused by external pressure, thus improving the overall design.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
