Technical Field
[0001] This utility model relates to the field of landscaping technology, specifically to a nozzle structure for landscaping. Background Technology
[0002] With the acceleration of urbanization, landscaping, as an important means to improve the urban ecological environment and enhance the quality of life of residents, is constantly increasing in scale and sophistication. Irrigation systems are the core link in landscaping maintenance, and nozzles, as key components that directly act on plants in the irrigation system, directly affect irrigation efficiency, water resource utilization, and plant growth. In diverse landscaping scenarios, different plants (such as trees, shrubs, lawns, and flowers) have significantly different requirements for irrigation volume, range, and precision. This places higher demands on the adaptability and flexibility of nozzles. At the same time, in order to cope with different irrigation tasks (such as daily maintenance, emergency watering, and pest and disease control), nozzles often need to be used in conjunction with different types of external equipment (such as water pipes and sprayers). Their ease of connection and versatility have also become important factors affecting operational efficiency. Currently, the nozzle structure commonly used in landscaping typically includes a shell, a nozzle housed inside the shell, and a pipe for connecting to the water source. Its working process is roughly as follows: water is connected to the water source through the rear pipe, flows through the channels inside the shell to the nozzle, and is finally sprayed out by the nozzle at a specific angle and range to irrigate the target plant area. To meet basic irrigation needs, some nozzles are designed with multiple nozzles to expand the irrigation range, or a single nozzle design is used to improve the accuracy of localized irrigation. When connecting to external equipment, the nozzle is usually connected to the external pipe through a fixed-specification threaded structure, relying on the tight fit of the threads to achieve a seal and prevent leakage. However, existing nozzle structures still have some shortcomings in practical applications: First, the spraying pattern is relatively fixed, and the number of nozzles and working status of most nozzles cannot be flexibly adjusted. If a single nozzle design is used, the nozzles need to be moved frequently when irrigating large areas, resulting in low efficiency. If a multi-nozzle design is used, it is easy to waste water resources when precisely irrigating rare plants or seedlings, and the plants may be damaged due to excessive water volume. Second, the compatibility with external equipment is poor. The connection structure of existing nozzles is mostly designed for specific pipe diameters. When it is necessary to replace different types of external pipes or equipment, it is often impossible to install due to pipe diameter mismatch, or additional adapter parts are required, making the operation cumbersome. Therefore, we propose a nozzle structure for landscaping. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a nozzle structure for landscaping that can flexibly adjust the water spraying mode to adapt to different irrigation needs, improve the compatibility and connection sealing with external equipment, and make the adjustment structure stable, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a nozzle structure for landscaping, including a shell, an inner cylinder, and uniformly distributed nozzles on the left side wall of the cylinder; it also includes an adjustment component and a replacement pipe. Adjustment component: It is located inside the housing and is configured to cooperate with the nozzle; Replacement pipe: It is threaded to the front end of the outer shell. A tapered cylinder is fixedly connected to the front side of the replacement pipe. The front end of the tapered cylinder is provided with a threaded groove. The cylinder wall of the tapered cylinder is provided with uniformly distributed deformation grooves. A rubber sealing sleeve is fixedly connected to the front side of the tapered cylinder. The rear end of the rubber sealing sleeve extends into the interior of the replacement pipe and is fixedly connected to the inner arc surface of the replacement pipe. It also includes a tapered inner hole nut, which is threadedly connected to a threaded groove, allowing for flexible adjustment of the water spraying mode to adapt to different irrigation needs, improving compatibility with external equipment and connection sealing, and ensuring stable adjustment structure.
[0005] Furthermore, the adjustment assembly includes a sealed bearing, a rotating frame, and rubber plugs. The rotating frame is rotatably connected to the middle of the housing via the sealed bearing. The middle of the rotating frame has a clearance hole corresponding to the central nozzle. The rubber plugs are respectively disposed at the upper and lower ends of the rear side of the rotating frame and are used in conjunction with the adjacent nozzles on the rear side. By rotating the rotating frame, the rubber plugs can selectively block some nozzles, thereby achieving the switching between single-hole and multi-hole water spray.
[0006] Furthermore, the adjustment assembly also includes a paddle and a clearance groove. The paddle is fixedly connected to the upper rear side of the rotating frame, and the outer arc wall of the outer shell has a clearance groove corresponding to the paddle on the right end. The paddle provides a convenient operating component for the rotation of the rotating frame, and the clearance groove provides room for the rotation of the paddle, making it easy for the user to adjust the position of the rotating frame.
[0007] Furthermore, the adjustment assembly also includes connecting plates, which are respectively disposed on the upper side of the outer arc surface of the housing and the right side of the outer arc surface of the housing. The connecting plates are used in conjunction with the upper end of the lever. The lever and the connecting plates can be fixed by bolts or other connecting parts, thereby stabilizing the position of the rotating frame, ensuring the stability of the water spray mode, and preventing changes in the water spray state due to accidental contact.
[0008] Furthermore, the adjustment assembly also includes ribs and rib grooves. The rib grooves are respectively opened on the left and right sides of the outer arc wall of the outer shell, and the ribs are respectively set on the left and right sides of the outer arc surface of the cylinder. The ribs are all slidably connected to the laterally adjacent rib grooves. The sliding cooperation between the ribs and the rib grooves provides guidance and limiting function for the lateral movement of the cylinder, ensuring the stability of the cylinder movement process.
[0009] Furthermore, the adjustment assembly also includes a tightening screw, which is threaded to the right end of the right side rib. A limit plate is fixedly connected to the right side of the outer arc surface of the housing. The lower end of the tightening screw contacts the limit plate. By tightening the tightening screw, the rib and the limit plate can be fixed, thereby locking the position of the cylinder and preventing the cylinder from moving due to water flow impact during water spraying, thus ensuring the stability of the water spraying effect.
[0010] Furthermore, a funnel-shaped connecting pipe is fixedly connected to the rear end of the inner arc surface of the outer shell. The front end of the funnel-shaped connecting pipe is connected to the rear end of the cylinder through a corrugated pipe. The funnel-shaped connecting pipe facilitates the smooth flow of water into the device. The corrugated pipe is extensible and can adapt to the lateral movement of the cylinder, ensuring stable water delivery inside the device and preventing pipe breakage or leakage due to cylinder movement.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This nozzle structure for landscaping has the following advantages: 1. By adjusting the coordinated action of components such as the rotating frame, rubber plug, and lever in the assembly, the single-hole and multi-hole spraying modes can be easily switched. When the rotating frame is in a vertical position, the rubber plug blocks part of the nozzle, and only the middle nozzle sprays water, which is suitable for localized precision irrigation. Rotating the rotating frame to remove the rubber plug from the nozzle enables simultaneous spraying of water from multiple holes, meeting the needs of large-area irrigation. This allows the nozzles to flexibly adapt to the irrigation needs of different plants and different areas in landscaping, improving the targeting and efficiency of irrigation.
[0012] 2. The combined design of a conical cylinder, deformation groove, and conical inner hole nut allows for adaptation to external nozzles of different pipe diameters: This design provides high versatility for connecting nozzles to external equipment. The deformation groove in the conical cylinder wall allows it to deform when the conical inner hole nut is tightened, tightly gripping the external nozzle tube through a rubber sealing sleeve. This not only securely fixes external nozzles of different pipe diameters but also enhances sealing performance through the tight contact of the rubber sealing sleeve, effectively preventing water leakage. The threaded connection between the pipe and the outer casing facilitates quick disassembly and assembly, allowing the nozzle to be flexibly matched with different types of external nozzles according to actual irrigation needs. This expands the applicability of the equipment, reduces the operational difficulty when changing different nozzles, and improves ease of use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-7 This embodiment provides a technical solution: a nozzle structure for landscaping, including a shell 1, a cylinder 10 inside the shell 1, a funnel-shaped connecting pipe 13 fixedly connected to the rear end of the inner arc surface of the shell 1, the front end of the funnel-shaped connecting pipe 13 and the rear end of the cylinder 10 are connected in series by a corrugated pipe 12, the left side wall of the cylinder 10 is provided with uniformly distributed nozzles 11, and also includes an adjustment component 2 and a replacement pipe 3. Adjustment component 2: It is located inside the outer casing 1 and is configured to cooperate with the nozzle 11. Adjustment component 2 includes a sealed bearing 21, a rotating frame 22, and rubber plugs 23. The rotating frame 22 is rotatably connected to the middle of the outer casing 1 via the sealed bearing 21. The middle of the rotating frame 22 has a clearance hole corresponding to the middle nozzle 11. The rubber plugs 23 are respectively set at the upper and lower ends of the rear side of the rotating frame 22 and are evenly used to cooperate with the adjacent nozzles 11 on the rear side. Adjustment component 2 also includes a lever 24 and a clearance groove 26. The lever 24 is fixedly connected to the upper end of the rear side of the rotating frame 22. The right end of the outer arc wall of the outer casing 1 has a clearance groove 26 corresponding to the lever 24. Adjustment component 2 also includes a connecting plate 25. The connecting plate 25 is respectively set on the upper side of the outer arc surface of the outer casing 1 and the outer side of the outer casing 1. On the right side of the arc surface, the connecting plates 25 are used in conjunction with the upper end of the lever 24 (the middle part of the connecting plate 25 and the upper end of the lever 24 are both provided with connecting holes. The external bolts are inserted into the two adjacent connecting holes, and then the nuts are screwed on and tightened. The hexagonal heads of the nuts and bolts hold the lever 24 and the adjacent connecting plate 25 together, thereby limiting the position of the lever 24). The adjusting assembly 2 also includes ribs 27 and rib grooves 28. The rib grooves 28 are respectively opened on the left and right sides of the outer arc wall of the outer shell 1. The ribs 27 are respectively set on the left and right sides of the outer arc surface of the cylinder 10. The ribs 27 are all slidably connected to the laterally adjacent rib grooves 28. The adjusting assembly 2 also includes a tightening screw 29, which is threaded to the right end of the right side rib 27. The right side of the outer arc surface of the outer shell 1 is fixedly connected to a limit plate 9. The lower end of the tightening screw 29 contacts the limiting plate 9. During normal use, if it is not necessary to connect an external nozzle, the replacement pipe 3 can be separated from the outer casing 1. At this time, the water spray state is controlled by adjusting the component 2 to achieve the switching between single-hole water spray and multi-hole water spray. In specific operation, the rotating frame 22 is rotated by the movement of the lever 24 in the clearance groove 26. When the rotating frame 22 is adjusted to the vertical position, the cylinder 10 is slidable. Since the rib 27 and the rib groove 28 are slidably connected, the cylinder 10 can move forward stably. During the movement, the rubber plugs 23 at the upper and lower ends of the rear end of the rotating frame 22 will be inserted into the interior of the upper and lower nozzles 11, blocking the two nozzles 11. At this time, water enters from the funnel-shaped connecting pipe 13, is transported to the cylinder 10 through the corrugated pipe 12, and is then transported to the cylinder 10. With the upper and lower nozzles 11 blocked, water can only spray from the middle nozzle 11, achieving single-hole spraying. For multi-hole spraying, the lever 24 can be rotated, causing the rotating frame 22 to no longer be vertical. At this point, the rubber plug 23 disengages from the upper and lower nozzles 11, and water enters through the funnel-shaped connecting pipe 13, passing through the corrugated pipe 12 and the cylinder 10, ultimately spraying from multiple unblocked nozzles 11, achieving multi-hole spraying. Furthermore, the connecting plate 25 can cooperate with the lever 24, fixing its position with bolts and nuts, thereby fixing the state of the rotating frame 22 and ensuring stable spraying. The sealed bearing 21 ensures the sealing of the rotating frame 22 during rotation, preventing leakage, while the corrugated pipe 12 accommodates the sliding of the cylinder 10, ensuring smooth water flow.Simultaneously tighten the tightening screw 29. The tightening screw 29 and the limiting plate 9 restrict the position of the cylinder 10 through friction. When water flows through the device, the front end of the nozzle 11 is always located in front of the clearance groove 26, facilitating adjustment of single-hole or multi-hole water spray. Replacement pipe 3: It is threadedly connected to the front end of the outer shell 1. A tapered cylinder 4 is fixedly connected to the front side of the replacement pipe 3. The front end of the tapered cylinder 4 is provided with a threaded groove 5. The cylinder wall of the tapered cylinder 4 is provided with uniformly distributed deformation grooves 6. A rubber sealing sleeve 8 is fixedly connected to the front side of the tapered cylinder 4. The rear end of the rubber sealing sleeve 8 extends into the interior of the replacement pipe 3 and is fixedly connected to the inner arc surface of the replacement pipe 3. This includes a tapered inner nut 7, which is threadedly connected to the threaded groove 5. When an external nozzle needs to be installed, the replacement pipe 3 is first threadedly connected to the front end of the outer casing 1 to complete the basic assembly. Then, the tube of the external nozzle is inserted into the inside of the tapered cylinder 4. Next, the tapered inner nut 7 is tightened. Since the tapered inner nut 7 is threadedly connected to the threaded groove 5, the inner wall of the tapered inner nut 7 will exert a squeezing effect on the tapered cylinder 4 during the tightening process. The cylinder wall of the tapered cylinder 4 has uniformly distributed deformation grooves 6, which allows the tapered cylinder 4 to deform when squeezed. This allows the rubber sealing sleeve 8 to tightly hold the tube of the external nozzle. The rubber sealing sleeve 8 is in close contact with the outer arc surface of the tube of the external nozzle, enhancing the sealing effect, preventing water leakage, and achieving a stable installation of the external nozzle. External water enters from the funnel-shaped connecting pipe 13, is transported to the cylinder 10 through the corrugated pipe 12, and is sprayed out by the nozzle 11. After passing through the replacement pipe 3, it is finally sprayed out through the installed external nozzle, which facilitates the installation of nozzles with different pipe diameters.
[0017] The working principle of the nozzle structure for landscaping provided by this utility model is as follows: When an external nozzle needs to be installed, first connect the replacement pipe 3 to the front end of the outer casing 1 to complete the basic assembly. Then, insert the tube of the external nozzle into the interior of the conical cylinder 4. Next, tighten the conical inner hole nut 7. Since the conical inner hole nut 7 is threadedly connected to the threaded groove 5, the inner wall of the conical inner hole nut 7 will exert a squeezing effect on the conical cylinder 4 during the tightening process. The cylinder wall of the conical cylinder 4 has evenly distributed deformation grooves 6, which allows the conical cylinder 4 to deform when squeezed, thereby tightly holding the tube of the external nozzle through the rubber sealing sleeve 8. The pipe section of the external nozzle is in close contact with the outer arc surface to enhance the sealing effect, prevent water leakage, and achieve a stable installation of the external nozzle. External water enters from the funnel-shaped connecting pipe 13, is transported through the corrugated pipe 12 to the cylinder 10, and is sprayed out by the nozzle 11. After passing through the replacement pipe 3, it is finally sprayed out through the installed external nozzle. During normal use, if the external nozzle is not connected, the replacement pipe 3 can be separated from the outer casing 1. At this time, the water spray state is controlled by adjusting the component 2 to achieve the switching between single-hole water spray and multi-hole water spray. In specific operation, the rotating frame 22 is rotated by the movement of the lever 24 in the clearance groove 26. When the rotating frame 22 is adjusted to the vertical position, the sliding... The cylinder 10, due to the sliding connection between the ribs 27 and the rib grooves 28, can move stably forward. During the movement, the rubber plugs 23 at the upper and lower ends of the rear end of the rotating frame 22 will insert into the interior of the upper and lower nozzles 11, blocking them. At this time, water enters from the funnel-shaped connecting pipe 13, is transported to the cylinder 10 through the corrugated pipe 12, and because the upper and lower nozzles 11 are blocked, water can only be sprayed from the middle nozzle 11, achieving single-hole water spraying. If multi-hole water spraying is required, the lever 24 can be rotated to make the rotating frame 22 no longer in a vertical state. At this time, the rubber plugs 23 disengage from the upper and lower nozzles 11, and water enters from the funnel-shaped connecting pipe 13. After passing through the corrugated pipe 12 and the cylinder 10 in sequence, water can finally be sprayed from multiple unblocked nozzles 11, realizing multi-hole water spraying. In addition, the connecting plate 25 can cooperate with the lever 24, and the position of the lever 24 can be fixed by bolts and nuts, thereby fixing the state of the rotating frame 22 and ensuring the stability of the water spraying mode. The sealed bearing 21 can ensure the sealing of the rotating frame 22 when it rotates to prevent water leakage. The corrugated pipe 12 can adapt to the sliding of the cylinder 10 to ensure smooth water delivery. At the same time, tightening the top screw 29, the top screw 29 and the limiting plate 9 restrict the position of the cylinder 10 through friction. When there is water flow in the device, the front end of the nozzle 11 is always located in front of the avoidance groove 26.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
