Description

An adjustable spray structure Technical Field

[0001] This utility model relates to the field of spray equipment, and in particular, to an adjustable spray structure. Background Technology

[0002] Currently, there are various spray structures available on the market for irrigating flowers and plants. Figure 1 shows one such spray structure, including a main nozzle 1, a nozzle 2, and an atomizing net 5. In this structure, the nozzle 2 is fixed to the end of the main nozzle 1, receiving and discharging the water flow from the main nozzle 1. The atomizing net 5 is fixed to the front of the nozzle 2 by a bracket 4, located in the path of the water flow after it exits from the nozzle 2. After water enters the nozzle 2 from the main nozzle 1, it is sprayed out from the outlet 3 of the nozzle 2 and impacts the atomizing net 5. After atomization, the water finally passes through the atomizing net 5 and is sprayed onto the flowers and plants. This method of achieving atomization spraying through water impacting the atomizing net can, to a certain extent, meet basic irrigation needs.

[0003] However, the aforementioned spraying structure has a major drawback: its spraying range is fixed and cannot be adjusted according to actual needs. This means that users cannot flexibly adjust the size of the spraying range based on different plant species, planting area size, or specific irrigation goals, limiting the flexibility and applicability of the spraying structure. When concentrated irrigation of a specific small area is needed, or when the spraying range needs to be expanded to cover a wider area, the existing structure is difficult to adapt, potentially leading to uneven irrigation, water waste, or ineffective coverage of the target area. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide an adjustable spray structure to flexibly adjust the size of the spray range.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an adjustable spray structure, including a main spray pipe and a nozzle, wherein the nozzle is connected to and communicates with the main spray pipe, and further includes an adjusting member, wherein the adjusting member passes through the outlet of the nozzle and is connected to the main spray pipe and / or the nozzle, and the outer wall of the adjusting member is provided with a guiding slope for diffusing the fluid sprayed from the outlet outward, and the adjusting member moves and is positioned in a direction closer to or further away from the nozzle.

[0006] To achieve the above technical solution, water flows from the main nozzle into the spray head. An adjusting component with a guide ramp passes through the spray head outlet and connects to the main nozzle. By moving and positioning this adjusting component in a direction closer to or further from the spray head, the relative position of the guide ramp at the spray head outlet can be changed. Changing the position of the guide ramp affects the interaction between the water stream and the guide ramp during spraying, thereby altering the water stream's dispersion state and angle, ultimately adjusting the spray range of the spray structure. This design provides flexible spray range control capabilities, allowing adjustment of the spray area size according to actual needs, overcoming the problems of fixed spray range and lack of flexibility in existing technologies, and improving practicality and applicability.

[0007] In a preferred embodiment of this utility model, the adjusting member is connected to the main nozzle via a connecting member, the connecting member being disposed between the main nozzle and the nozzle head, and the adjusting member being connected to the connecting member.

[0008] The above technical solution, achieved by introducing a connector as an intermediate component, provides excellent disassembly and replaceability. Users can easily and quickly detach the adjusting component from the connector, or disassemble the connector and adjusting component as a single assembly, greatly simplifying the product's maintenance, cleaning, and repair processes.

[0009] In a preferred embodiment of this utility model, the adjusting member includes a connecting section and an adjusting section, the connecting section is connected to the adjusting section, the connecting section is threadedly connected to the connecting member, and the guide slope is formed on the adjusting section.

[0010] To achieve the above technical solution, the user rotates the adjusting component, utilizing the principle of threaded engagement to achieve precise axial movement of the adjusting component. The self-locking property of the thread ensures that once the adjusting component is set to a certain position, it can stably and reliably maintain that position without slipping or shifting due to water pressure fluctuations or vibrations, thus providing stable positioning.

[0011] As a preferred embodiment of this utility model, the adjusting section has a rotating part, and the rotating part is provided with an anti-slip groove.

[0012] The above technical solution is implemented to facilitate its use in the rotary adjustment section.

[0013] In a preferred embodiment of this utility model, a limiting member is connected to the connecting member, and a step is formed between the limiting member and the connecting member. A sealing ring is fixedly connected to the step, and the limiting member is inserted into the main nozzle and the end of the main nozzle is placed in the step.

[0014] To achieve the above technical solution, during assembly, the limiting component first penetrates into the interior of the main nozzle, while the end of the main nozzle is guided and placed within the step formed by the connector. This ensures that the connector can be accurately and stably installed onto the main nozzle. The sealing ring located on the step forms a reliable seal between the end of the main nozzle and the step of the connector, effectively preventing water leakage from the connection.

[0015] As a preferred embodiment of this utility model, the connector is provided with a water guide hole, one end of which is connected to the main spray pipe and the other end of which is connected to the nozzle.

[0016] To achieve the above technical solution, the water guide hole becomes the sole channel for water flow from the main nozzle into the connector and nozzle. The cross-sectional area of ​​the water guide hole is significantly smaller than that of the main nozzle, resulting in a significantly increased water velocity as the water passes through it. This provides a sufficient water source velocity for subsequent effective impact atomization, ensuring the structure can perform its spraying function normally and efficiently.

[0017] As a preferred embodiment of this utility model, a sealing ring is provided between the inner wall of the nozzle and the connecting member, and the water outlet of the nozzle is located inside the sealing ring.

[0018] To achieve the above technical solution, the sealing ring forms a reliable sealed space in the area where the connector mates with the nozzle. This ensures that the water flow, after entering the nozzle from the connector, is completely confined inside the nozzle, preventing leakage from the connection gap. It effectively maintains the water pressure inside the nozzle, ensuring that all water entering the nozzle is correctly guided to the outlet, thereby guaranteeing stable and normal spray performance, avoiding water waste, and improving the sealing reliability and working efficiency of the entire spray structure.

[0019] As a preferred embodiment of this utility model, a positioning ring groove is provided on the inner wall of the nozzle, the water outlet of the nozzle is located in the positioning ring groove, and the sealing ring is placed in the positioning ring groove.

[0020] The above technical solution provides a very precise and stable space for the positioning ring groove to accommodate and position the sealing ring, effectively preventing the sealing ring from shifting, deforming or even being squeezed out under water pressure or external force, and significantly improving the reliability and durability of the seal.

[0021] In a preferred embodiment of this utility model, the nozzle is threadedly connected to the main spray pipe.

[0022] The above technical solution achieves the advantage of threaded connection, which is easy to screw in and out, greatly facilitating the installation, disassembly, daily maintenance, cleaning, or replacement of the nozzle when needed.

[0023] In a preferred embodiment of this utility model, the nozzle is connected to an atomizing net via a bracket, and the nozzle outlet faces the atomizing net.

[0024] The above technical solution enables water to be precisely and directly impacted by the atomizing mesh after being sprayed from the nozzle. The atomizing mesh serves as the primary impact atomizing element, utilizing the high-speed impact force of the water flow to physically disperse it into finer, more uniform droplets. By precisely guiding the water flow to impact the atomizing mesh, secondary atomization of the water flow can be efficiently achieved, ultimately forming a fine, uniform spray suitable for spraying flowers and plants, thus improving irrigation effectiveness and coverage uniformity.

[0031] The specific embodiments of this utility model will be further described in detail below with reference to Figures 2 to 5, so that the technical solution of this utility model can be more easily understood and mastered.

[0032] An adjustable spray structure includes a main spray pipe 1 and a nozzle 2. The nozzle 2 is threadedly connected to and communicates with the main spray pipe 1, and the end of the nozzle 2 away from the main spray pipe 1 has a water outlet 3.

[0033] A bracket 4 is fixedly connected to the outer wall of the nozzle 2. An atomizing net 5 is fixedly connected to the end of the bracket 4 away from the nozzle 2, and the water outlet 3 of the nozzle 2 faces the atomizing net 5.

[0034] A cylindrical connector 6 is disposed between the main nozzle 1 and the nozzle 2. A limiting member 7 is integrally connected to one end of the connector 6, and the limiting member 7 is coaxially arranged with the connector 6. A step 8 is formed between the limiting member 7 and the connector 6, and a sealing ring 9 is fixedly connected to the step 8. The limiting member 7 passes into the main nozzle 1 and places the end of the main nozzle 1 in the step 8. The outer surface of the limiting member 7 is used to fit against the inner wall of the main nozzle 1. The outer diameter of the connector 6 is larger than the outer diameter of the limiting member 7 and smaller than or equal to the outer diameter of the main nozzle 1.

[0035] A water guide hole 10 is provided on the connector 6. One end of the water guide hole 10 passes through the limiting member 7 and communicates with the main spray pipe 1, and the other end of the water guide hole 10 communicates with the nozzle 2. There are two water guide holes 10, which are evenly distributed along the axis of the connector 6.

[0036] A positioning ring groove 11 is provided on the inner wall of the nozzle 2, and the water outlet 3 of the nozzle 2 is located in the positioning ring groove 11. The sealing ring 12 is placed in the positioning ring groove 11. The sealing ring 12 is used to abut against the end of the connector 6 away from the limiting member 7, and the water guide hole 10 is located in the sealing ring 12.

[0037] The adjusting component 13 includes a connecting section 14 and an adjusting section 15. The connecting section 14 and the adjusting section 15 are integrally connected and coaxially arranged. The connecting section 14 passes through the nozzle 2 from the outlet 3 and is threadedly connected to the connector 6. The connecting section 14 is located between the two guide holes 10. A guide slope 16 is provided on the adjusting section 15, which is located at the end of the nozzle 2 furthest from the main nozzle pipe 1. The outlet 3 faces the guide slope 16, and the fluid exiting from the outlet 3 diffuses outward after being conducted by the guide slope 16. The guide slope 16 is a conical surface.

[0038] The adjustment section 15 has a rotating part 17, and anti-slip grooves 18 are provided on the rotating part 17. Multiple anti-slip grooves 18 are evenly distributed along the axis of the rotating part 17.

[0039] During installation of the adjustable spray structure, first insert the limiting member 7 of the connector 6 into the end of the main spray pipe 1, with the end of the main spray pipe 1 abutting against the sealing ring 9 at the step 8. Next, thread the nozzle 2, with the sealing ring 12 already inserted, into the main spray pipe 1. This ensures that the sealing ring 12 is tightly abutted against the connector 6.

[0040] Then, screw the adjusting member 13 into the threaded hole on the connector 6 through the outlet 3 of the nozzle 2. Finally, fix the bracket 4 to the outer wall of the nozzle 2 and fix the atomizing net 5 to the bracket 4.

[0041] In use, water flows from the main nozzle 1 through the water guide hole 10 of the connector 6 and into the nozzle 2. The user holds the rotating part 17 and rotates it, which, through the threaded engagement, allows the adjusting part 13 and the guide ramp 16 to move precisely along the axial direction. The self-locking nature of the thread ensures stable adjustment. The position change of the guide ramp 16 precisely controls the state of the water flow impacting the atomizing net 5 in front, achieving fine adjustment of the spray range.

[0042] The closer the guide slope 16 is to the nozzle 2, the larger the spraying range; the farther the guide slope 16 is from the nozzle 2, the smaller the spraying range.

[0043] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
