Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler heads, in particular to a gardening and greening sprinkler device. Background Art

[0002] Splashing disks are often installed on the sprinklers used in landscaping to increase the spraying range of the sprinklers. In order to increase the sputtering range, the sputtering disk is usually rotatable.

[0003] The existing Chinese utility model patent with authorization announcement number CN210787803U discloses a sputtering disk actively rotating landscaping nozzle. The nozzle is provided with a rotating shaft. One end of the rotating shaft extends out of the nozzle and is fixedly connected to the sputtering disk, and the other end extends into the nozzle and is connected to the impeller. When water is sprayed out of the nozzle, the water flow drives the impeller to rotate and then drives the sputtering disk to rotate.

[0004] However, the nozzle's seal at the rotating shaft in the aforementioned technical solution is weak, making it prone to leakage over extended use. This reduces the water pressure of the nozzle, and leakage can also lead to water accumulation, which can reduce irrigation uniformity. To address this technical issue, a Chinese utility model patent with authorization publication number CN208853041U discloses a landscaping sprinkler nozzle. The nozzle has a column fixedly mounted at its axial end, to which an impeller is rotatably connected. The impeller forms a splash disk. When water is ejected from the nozzle's axial end, it strikes the impeller, causing it to rotate.

[0005] However, there is a gap between two adjacent blades in the impeller. If the water flow ejected from the axial end of the nozzle enters the gap, it will not hit the impeller, and this part of the water flow will not be splashed; or the water flow entering the above gap may be reflected back and forth between the two adjacent blades, unable to form splashing, and finally flow along the nozzle to the root of the nozzle to form accumulated water. Utility Model Content

[0006] The utility model aims to provide a gardening spraying device to solve the technical problem in the prior art that the fan impeller is used as a sputtering disk and has a poor sputtering effect.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A landscaping sprinkler device includes a nozzle, one axial end of the nozzle is a connecting end, and the other end is an injection end. The injection end is provided with a spray hole connected to the inner cavity of the nozzle. A connecting column is fixedly provided at the center of the injection end of the nozzle, and a sputtering disk is rotatably mounted on the connecting column. The spray hole faces the sputtering disk. The sputtering disk is bowl-shaped and the opening faces away from the nozzle. A plurality of spiral guide grooves are provided on the outer wall of the sputtering disk.

[0009] The utility model is further configured as follows: one end of the guide groove passes through one end of the sputtering disk opening.

[0010] The utility model is further configured such that: a rounded transition is provided between the side wall of the guide groove and the outer wall of the sputtering disk.

[0011] The utility model is further configured as follows: a mounting hole is opened at the center of the bottom of the sputtering disk, and a bearing is arranged between the inner wall of the mounting hole and the connecting column.

[0012] The utility model is further configured as follows: the bearing includes an inner ring, a roller and an outer ring, the outer ring includes an outer ring body and an outward-turned limiting edge arranged at one axial end of the outer ring body, and the limiting edge is engaged with the bottom inner side of the sputtering disk.

[0013] The utility model is further configured as follows: the connecting column includes a large diameter section and a small diameter section connected to each other, a shaft shoulder is formed between the large diameter section and the small diameter section, a shaft sleeve is sleeved on the small diameter section for tightening the inner ring of the bearing, and a shaft sleeve fixing nut is also threadedly connected to the small diameter section for pressing the shaft sleeve.

[0014] The utility model is further configured such that the outer diameter of the large diameter section is larger than the inner diameter of the mounting hole so that the shaft shoulder is engaged with the outer side of the bottom of the sputtering disk.

[0015] The utility model is further configured such that one end of the spray hole facing the outside of the spray head is inclined in a direction away from the axis of the spray head.

[0016] In summary, the beneficial technical effects of the present invention are:

[0017] During use, the water jetting from the nozzles directly impacts the outer wall of the construction disk. The water jetting into the diversion groove exerts force on the inner wall of the diversion groove, causing the splash disk to rotate. At the same time, some of the water jetting into the diversion groove can flow upward along the diversion groove, splashing out at a certain angle. This increases the splashing angle, further improving the splashing effect of the water flow and enhancing irrigation uniformity. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described clearly and completely below with reference to the embodiments.

[0023] See attached Figure 1 A landscaping sprinkler device includes a nozzle 1, one axial end of which is a connection end and the other end is a spray end. The connection end is open and has external threads formed thereon to facilitate connection of the nozzle 1 to a water pipe. Once the nozzle 1 is connected to the water pipe, the inner cavity of the nozzle 1 is connected to the water pipe. The end wall of the spray end is provided with a spray hole 2 that communicates with the inner cavity of the nozzle 1. Three spray holes 2 are evenly distributed along the axial direction of the nozzle 1. The end of the spray hole 2 facing the outside of the nozzle 1 is inclined in a direction away from the axis of the nozzle 1.

[0024] A connecting post 3 is fixedly mounted at the center of the spray end of the nozzle 1, on which a sputtering disk 4 is rotatably mounted. The sputtering disk 4 is bowl-shaped, with its opening facing away from the nozzle 1. A mounting hole is defined along the centerline of the bottom of the sputtering disk 4. A bearing 5 is positioned between the inner wall of the mounting hole and the connecting post 3 to ensure smooth rotation of the sputtering disk 4.

[0025] See attached Figure 2 and attached Figure 3 The bearing 5 includes an inner ring 51, a roller 52, and an outer ring. The outer ring includes an outer ring body 53 and an outward-turned stop edge 54 provided at one axial end of the outer ring body 53. The stop edge 54 engages with the inner side of the bottom of the sputtering disk 4. When the water jetted from the nozzle 2 impacts the sputtering disk 4, it will generate an upward impact force on the sputtering disk 4. The stop edge 54 can balance this impact force and ensure the stability of the sputtering disk 4. The connecting column 3 includes a large-diameter section 31 and a small-diameter section 32 that are interconnected. A shoulder is formed between the large-diameter section 31 and the small-diameter section 32. The outer diameter of the large-diameter section 31 is larger than the inner diameter of the mounting hole, so that the shoulder engages with the outer side of the bottom of the sputtering disk 4. The inner ring 51 of the bearing 5 is sleeved on the small diameter section 32, and one axial end of the inner ring 51 of the bearing 5 is engaged with the shaft shoulder stop. The small diameter section 32 is sleeved with a shaft sleeve 6 for tightening the inner ring 51 of the bearing 5, and the small diameter section 32 is also threadedly connected with a shaft sleeve 6 fixing nut 7 for pressing the shaft sleeve 6.

[0026] A plurality of spiral guide grooves 8 are provided on the outer wall of the sputtering disk 4 . One end of the guide groove 8 passes through the open end of the sputtering disk 4 . The side wall of the guide groove 8 and the outer wall of the sputtering disk 4 have a rounded transition.

[0027] During use, the water jetted from the spray hole 2 directly impacts the outer wall of the construction disk. The water jetting into the diversion groove 8 exerts a force on the inner wall of the diversion groove 8, thereby causing the splash disk 4 to rotate. At the same time, part of the water jetting into the diversion groove 8 can also flow upward along the diversion groove 8, thereby splashing out at a certain angle, increasing the splashing angle, further improving the splashing effect of the water flow, and improving the uniformity of irrigation.

[0028] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
