Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a multi-range spraying device for landscaping. Background Technology

[0002] Landscape greening projects are projects that construct scenic gardens and green spaces. Landscape greening provides people with a good place for rest, cultural entertainment, getting close to nature, and fulfilling people's desire to return to nature. It is an important measure to protect the ecological environment and improve the urban living environment.

[0003] Garden vegetation requires watering during its growth process. However, existing sprinkler systems are mostly buried underground, connecting multiple sprinkler units via water pipes and then supplying water through pumps. This method involves a large amount of construction work and fixed locations. Moreover, existing sprinkler heads have few outlets, resulting in low spraying efficiency. To address this, we propose a multi-range sprinkler system for landscaping. Utility Model Content

[0004] To address the shortcomings of existing garden irrigation sprinklers, which have limited water outlets and thus limited spraying efficiency, this utility model provides a multi-range spraying device for landscaping. This device features automatic rotation and can spray water outwards through multiple water outlets, resulting in a large and wide spraying area, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a multi-range spraying device for landscaping, including a nozzle mounted on top of a retractable bracket;

[0007] The nozzle includes a support tube, one end of which is connected to a rotary joint, and the other end has multiple baffles on its side. The baffles are fan-shaped with their narrower end facing the support tube. The baffles are at a certain angle to the axis of the support tube, and both the upper and lower sides of the baffles are upward-convex arc surfaces.

[0008] The top edge of one side of the baffle is provided with an upper arc-shaped baffle and the bottom is provided with a lower arc-shaped baffle. The lower arc-shaped baffle and the upper arc-shaped baffle form a fan-shaped water outlet groove.

[0009] Multiple baffles are distributed around the top of the support pipe, the end of the support pipe is located at the bottom of the space enclosed by the baffles, the corners of the baffles are connected to the edge of the end of the support pipe, the outlet of the end of the support pipe is located at the center of the space, and the top of the space is sealed by a sealing block.

[0010] Among them, there is a water outlet gap between the two adjacent baffles near the end of the support pipe, and the upper arc-shaped baffle and the lower arc-shaped baffle near the support pipe are respectively connected to the side of the adjacent baffle.

[0011] Preferably, the included angle is between 15° and 75°.

[0012] Preferably, the upper arc-shaped baffle is connected to a first baffle at one end near the support tube, and the first baffle is connected to the baffle adjacent to it.

[0013] Preferably, the first baffle and the lower arc-shaped baffle are connected by a second baffle, the second baffle is connected to the baffle adjacent to it, and the channel formed by the second baffle and the end of the water outlet trough near the support pipe is the water outlet, and the water outlet and the water outlet gap are connected.

[0014] Preferably, the top of the sealing block is provided with a conical head, which is located at the center of the bottom surface of the sealing block, and the conical head and the support tube are coaxial.

[0015] Preferably, the rotary joint includes a first pipe joint coaxially mounted at the bottom of the support pipe, and a tubular support is built into the other end of the first pipe joint. The top side of the tubular support is provided with at least one sealing groove, and a sealing ring that elastically contacts the inner wall of the first pipe joint is provided in the sealing groove.

[0016] The bottom of the first pipe joint is provided with an annular cavity, and the annular cavity and the tubular support are connected by a bearing. The bottom of the tubular support extends out of the first pipe joint and is coaxially connected to the top of the second pipe joint. The second pipe joint is threadedly connected to the top of the retractable bracket.

[0017] Preferably, the retractable bracket includes a mounting tube, with multiple first support rods rotatably connected to the top side of the mounting tube, and a second support rod movably inserted into the first support rod.

[0018] A sliding sleeve is slidably connected below the mounting tube. A connecting rod is provided between the first support rod and the sliding sleeve, and the two ends of the connecting rod are rotatably connected to the first support rod and the sliding sleeve, respectively.

[0019] The installation pipe has an adjustable pipe inserted into it. The two ends of the adjustable pipe are respectively wrapped around the two ends of the installation pipe.

[0020] Preferably, the top of the mounting tube, the bottom of the first support rod, and the sliding sleeve are all provided with threaded locking bolts.

[0021] Compared with the prior art, when this utility model is used, because there is a certain angle between the baffle and the axis of the support pipe, when water is sprayed out from the water outlet gap, it will directly impact the baffle, and the water pressure will generate a pressure perpendicular to it, thereby causing the support pipe to rotate. This causes the water flowing out from the water outlet opening to be distributed and thrown out in a fan shape, resulting in a large spraying area. Moreover, multiple water outlets move at the same time, which makes the spraying area large and the spraying efficiency high. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: a multi-range spraying device for landscaping, including a retractable support top. In actual use, the retractable support is convenient to store, open and carry. The nozzle is installed on the top, and then the support is opened and supported on the ground.

[0031] like Figure 6As shown, the retractable bracket includes a mounting tube 17. Multiple first support rods 16 are rotatably connected to the top side of the mounting tube 17. The first support rods 16 are hollow. A second support rod 20 is movably inserted inside the first support rod 16. In order to reduce the overall weight, the second support rod 20 is also hollow. The bottom of the second support rod 20 is provided with an anti-slip pad or has a conical structure. When in use, it is directly inserted into the ground to prevent slippage.

[0032] A sliding sleeve 18 is slidably connected below the mounting tube 17. A connecting rod 19 is provided between the first support rod 16 and the sliding sleeve 18, and the two ends of the connecting rod 19 are rotatably connected to the first support rod 16 and the sliding sleeve 18 respectively.

[0033] An adjusting tube 15 is movably inserted into the installation tube 17. Both ends of the adjusting tube 15 are attached to the ends of the installation tube. The bottom of the adjusting tube 15 is connected to the water supply pipe via a connector. In use, the connector is directly threaded onto the bottom of the adjusting tube. Simultaneously, threaded locking bolts are provided on the top of the installation tube 17, the bottom of the first support rod 16, and the sliding sleeve 18. Figure 6 As shown, when the sliding sleeve 18 moves down along the adjusting tube 15, it can drive each connecting rod 19 to open simultaneously, so that each first support rod 16 is also opened simultaneously, thus opening the bracket; when the sliding sleeve moves up, the first support rod 16 and the connecting rod are simultaneously retracted, so the entire bracket is easy to open and retract.

[0034] Additionally, the top of the retractable bracket is equipped with a matching nozzle. The specific working process is as follows: when external high-pressure water enters the regulating pipe 15 through the water supply pipe, the water in the regulating pipe 15 will spray out from the nozzle. The nozzle specifically includes a support pipe 8. One end of the support pipe 8 is connected to the rotary joint, and the other end has multiple baffles 1 on its side. The baffles 1 have a fan-shaped structure and the narrow end of them faces the support pipe 8.

[0035] Both the upper and lower sides of the baffle 1 are upward-convex arc-shaped surfaces 21. The top edge of one side of the baffle 1 is provided with an upper arc-shaped baffle 2 and its bottom is provided with a lower arc-shaped baffle 7. The lower arc-shaped baffle 7 and the upper arc-shaped baffle 2 form a fan-shaped water outlet groove 6, which is also a fan-shaped structure.

[0036] Multiple baffles 1 are distributed around the top of the support pipe 8. The end of the support pipe 8 is located at the bottom of the space enclosed by the baffles 1. The corners of the baffles 1 are connected to the edge of the end of the support pipe 8. The water outlet at the end of the support pipe 8 is located at the center of the space. The top of the space is sealed by a sealing block 4, that is, the sealing block 4 is located above the space enclosed by the baffles 1. The sealing block 4 is sealed and connected to each baffle 1, so that the space forms a cavity with side water outlet and top sealing. When the water in the regulating pipe 15 flows into the support pipe 8, the water will quickly fill the entire space enclosed by the baffles 1 from the top of the support pipe 8.

[0037] A water outlet gap is provided between the two adjacent baffles near the end of the support pipe, causing water to spray out quickly from the water outlet gap. The upper arc-shaped baffle 2 and the lower arc-shaped baffle 7 near the end of the support pipe 8 are respectively connected to the side of the adjacent baffle 1.

[0038] Most importantly, such as Figure 4 As shown, there is a certain angle between the baffle 1 and the axis of the support pipe 8, ranging from 15° to 75°. When water is sprayed out from the water outlet gap, it will directly impact the baffle 1, and the water pressure will generate a pressure F perpendicular to it (e.g., Figure 4 (As indicated by the middle arrow), this pressure F will cause the support tube 8 to rotate;

[0039] Furthermore, due to the fan-shaped structure of the water outlet 6, the water flowing out from the opening of the water outlet 6 will be distributed and flung out in a fan shape, resulting in a large spraying area. Moreover, the simultaneous movement of multiple water outlet 6s ensures both a large spraying area and high spraying efficiency.

[0040] Furthermore, the upper arc-shaped baffle 2 is connected to a first baffle 3 at one end near the support tube 8. The first baffle 3 is connected to the baffle 1 adjacent to it. The first baffle 3 is used to block the water flow from the top of the water outlet gap, and plays the role of blocking water.

[0041] The first baffle 3 and the lower arc-shaped baffle 7 are connected by the second baffle 5. The second baffle 5 is connected to the baffle 1 adjacent to it. The channel formed by the second baffle 5 and the end of the water outlet 6 near the support pipe 8 is the water outlet 11. The water outlet 11 is connected to the water outlet gap, allowing the water flowing out of the water outlet 11 to flow directly into the water outlet 6. Therefore, the second baffle 5 has a restraining effect on the flowing water.

[0042] Furthermore, a conical head 10 is provided at the top of the sealing block 4. The conical head 10 is located at the center of the bottom surface of the sealing block, and the conical head 10 and the support tube 8 are coaxial. Figure 5 As shown, the water sprayed from the top of the support pipe 8 will directly hit the conical head 10, which acts as a guide to evenly introduce the water flow into each outlet 11.

[0043] The above-mentioned rotary joint specifically includes a first pipe joint 9 coaxially installed at the bottom of the support tube 8. A tubular support 13 is built into the other end of the first pipe joint 9. At least one sealing groove 12 is provided on the top side of the tubular support 13. A sealing ring that elastically contacts the inner wall of the first pipe joint is provided in the sealing groove 12.

[0044] The bottom of the first pipe connector 9 has an annular cavity 22, which is connected to the tubular support 13 via a bearing. The bottom of the tubular support 13 extends outside the first pipe connector 9 and is coaxially connected to the top of the second pipe connector 14. The second pipe connector 14 is hexagonal in shape for easy tightening and loosening with a wrench. Figure 6 As shown, the second pipe fitting 14 is threaded onto the top of the regulating pipe 15.
