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.

[0019] Example like Figures 1-7 As shown in the figure, an embodiment of the present invention provides an anti-clogging buried telescopic sprinkler head device, including a housing 1. A limiting sleeve 2 is fixedly installed on the inner wall of the housing 1 near the lower side. A filter mechanism 3 is movably inserted into the limiting sleeve 2. An internal thread 4 is formed on the inner wall of the housing 1 below the filter mechanism 3. A conical cylinder 5 is placed on the upper surface of the limiting sleeve 2, and the lower surface of the conical cylinder 5 is an open structure. A first rubber sealing ring 6 is fixedly installed on the inner wall of the conical cylinder 5 near the lower side, and a sealing structure is formed between the first rubber sealing ring 6 and the inner wall of the housing 1.

A sealing ring 13 is installed on the upper surface of the outer shell 1 through a locking mechanism 12. The inner wall of the sealing ring 13 is in contact with the outer surface of the liquid distribution cylinder 8. The upper surface of the sealing ring 13 is horizontally flush with the upper surface of the sealing cap 10. A telescopic spring 14 is provided between the lower surface of the sealing ring 13 and the upper surface of the lower side wall of the conical cylinder 5.

[0020] like Figure 3 As shown, in some embodiments, the filtering mechanism 3 includes a filter screen 301, a bearing assembly 302, a rectangular rod 303, and a rubber scraper 304. The filter screen 301 is inserted into the limiting sleeve 2. A rectangular rod 303 is mounted on the bearing assembly 302 at the middle position of the upper side wall of the filter screen 301. A rubber scraper 304 is fixedly mounted on the lower edge of the left and right sides of the rectangular rod 303, and the rubber scraper 304 is movably fitted with the inner wall of the filter screen 301.

[0021] In this embodiment, the filter screen sleeve 301 can filter impurities in the water entering the conical cylinder 5. The rectangular rod 303 rotates with the rotating mechanism 7, causing the rectangular rod 303 to drive the rubber scraper 304 to rotate. The rubber scraper 304 filters the impurities adhering to the inner wall of the filter screen sleeve 301, making the filter screen sleeve 301 less likely to be covered and blocked by impurities, extending the service life of the filter screen sleeve 301. In addition, the filter screen sleeve 301 is easy to remove from the outer shell 1, making it convenient to replace or clean the filter screen sleeve 301.

[0022] like Figure 3 As shown, in some embodiments, the lower surface of the filter screen 301 is an open structure, the cross-section of the filter screen 301 is a T-shaped structure, and the mesh diameter of the filter screen 301 is 1 mm.

[0023] In this embodiment, water can flow into the filter screen 301 completely, and the filter screen 301 has a good filtration effect.

[0024] like Figure 2 As shown, in some embodiments, a second rubber sealing ring 15 is placed on the lower surface of the filter screen sleeve 301, and the diameter of the second rubber sealing ring 15 matches the inner diameter of the outer shell 1.

[0025] In this embodiment, the second rubber sealing ring 15 presses against the lower surface of the filter screen sleeve 301 and the spray rod to achieve a sealing effect.

[0026] like Figure 4 and Figure 5 As shown, in some embodiments, the rotating mechanism 7 includes a conduit 701, a first mechanical seal 702, a liquid inlet 703, a rectangular sleeve 704, and a turbine blade 705. The conduit 701 is installed in the upper side wall of the conical cylinder 5 through the first mechanical seal 702. The upper surface of the conduit 701 is fixedly embedded in the lower side wall of the liquid distribution cylinder 8. The upper surface of the conduit 701 has an open structure. Liquid inlet holes 703 are evenly opened on the side wall of the conduit 701 located inside the conical cylinder 5. The rectangular sleeve 704 is fixedly installed on the lower surface of the conduit 701, and the rectangular sleeve 704 is movably sleeved on the outside of the rectangular rod 303. The turbine blade 705 is installed on the rectangular sleeve 704 near the middle position.

[0027] In this embodiment, the first mechanical seal 702 enables the conduit 701 to rotate. The water in the conical cylinder 5 drives the turbine blade 705 to rotate, which in turn drives the rectangular sleeve 704 to rotate. The rectangular sleeve 704 then drives the rectangular rod 303 and the conduit 701 to rotate, and the conduit 701 can drive the liquid distribution cylinder 8 to rotate.

[0028] like Figure 4 and Figure 6 As shown, in some embodiments, the spraying mechanism 9 includes a liquid distribution box 901 and a nozzle 902. The liquid distribution box 901 is evenly installed on the inner walls of the liquid distribution cylinder 8 in the circumferential direction. The nozzle 902 is fixedly installed on the side wall of the liquid distribution cylinder 8 corresponding to the liquid distribution box 901, and the nozzle 902 is connected to the liquid distribution box 901.

[0029] In this embodiment, water in the liquid distribution box 901 is sprayed out through the nozzle 902 for irrigation.

[0030] like Figure 4 and Figure 6 As shown, in some embodiments, the adjusting mechanism 11 includes a rotating shaft 111, a second mechanical seal 112, a cylinder 113, and a through hole 114. The rotating shaft 111 is installed in the middle of the sealing cover 10 through the second mechanical seal 112. The cylinder 113 is fixedly installed on the lower surface of the rotating shaft 111, and the lower surface of the cylinder 113 is an open structure. Through holes 114 are provided on the side wall of the cylinder that fits against the liquid distribution box 901.

[0031] In this embodiment, the rotating shaft 111 rotates in the second mechanical seal 112, causing the rotating shaft 111 to drive the cylinder 113 to rotate, thereby adjusting the overlapping area of ​​the through hole 114 on the side wall of the cylinder 113 and the through hole 114 on the side wall of the liquid distribution box 901. This adjusts the water flow rate into the liquid distribution box 901, thereby adjusting the flow rate of the nozzle 902.

[0032] like Figure 7 As shown, in some embodiments, the side curvature of the liquid distribution box 901 facing the cylinder 113 is the same as the curvature of the cylinder 113, and the liquid distribution box 901 and the cylinder 113 are movably fitted together.

[0033] In this embodiment, the liquid distribution box 901 is fitted with the cylinder 113 to improve the sealing effect, and water can flow through the through hole 114.

[0034] like Figure 2 As shown, in some embodiments, a third rubber sealing ring 16 is provided between the lower surface of the sealing cap 10 and the upper surface of the liquid distribution cylinder 8.

[0035] In this embodiment, the third rubber sealing ring 16 improves the sealing effect between the lower surface of the sealing cover 10 and the lower surface of the liquid distribution cylinder 8.

[0036] like Figure 2 As shown, in some embodiments, the locking mechanism 12 includes a threaded hole 121 and a locking bolt 122. The side wall of the housing 1 and the sealing ring 13 are provided with three sets of threaded holes 121 along the circumferential direction, and the locking bolts 122 are threadedly installed in the threaded holes 121 corresponding to the housing 1 and the sealing ring 13.

[0037] In this embodiment, the locking bolt 122 is threaded into the threaded hole 121 to achieve the effect of installing the sealing ring 13 in the outer shell 1, so that the sealing ring 13 presses and limits the upper surface of the telescopic spring 14, and by adjusting the insertion length of the locking bolt 122, the locking bolt 122 is pressed against the outer surface of the conical cylinder 5 at different heights, thereby achieving the effect of adjusting the telescopic height of the nozzle 902.

[0038] In use, the conical cylinder 5 is placed on the upper surface of the limiting sleeve 2 inside the outer casing 1, and the telescopic spring 14 is placed on the upper surface of the lower side wall of the conical cylinder 5. The sealing ring 13 is inserted into the upper surface of the outer casing 1, and the locking bolt 122 in the locking mechanism 12 is threaded into the threaded hole 121, thus achieving the effect of installing the sealing ring 13 in the outer casing 1. This causes the sealing ring 13 to press and limit the upper surface of the telescopic spring 14. Depending on the usage environment, the height of the upward movement of the conical cylinder 5 is set, which is to set the height of the spraying mechanism 9. The length of the locking bolt 122 is adjusted, and in conjunction with the conical shape of the outer surface of the conical cylinder 5, when the conical cylinder 5 rises to a certain height, the three locking bolts 122 abut against the outer surface of the conical cylinder 5, achieving the effect of limiting the height. Then, the filter screen sleeve 301 in the filter mechanism 3 is inserted into the limiting sleeve 2, and the rectangular rod 303 is inserted into the rectangular sleeve 704 in the rotating mechanism 7. The second rubber sealing ring 15 is then placed on the lower surface of the filter screen sleeve 301, allowing the outer shell 1 to be installed on the sprinkler rod via the internal thread 4. Water from the sprinkler rod flows into the outer shell 1, and the filter screen sleeve 301 filters impurities from the water. High-pressure water flowing upwards through the filter screen sleeve 301 causes the conical cylinder 5 to move upwards as a whole. The conical cylinder 5 compresses the telescopic spring 14, causing the distribution cylinder 8 to move upwards. The spraying mechanism 9 leaks out from the side wall of the distribution cylinder 8. After the conical cylinder 5 reaches the set height, it is limited by three sets of locking bolts 122, and water inside the conical cylinder 5 flows through the inlet hole 70. 3. Water flows into the conduit 701. During this process, the water in the conical cylinder 5 drives the turbine blades 705 to rotate, which in turn drives the rectangular sleeve 704 to rotate. The rectangular sleeve 704 then drives the rectangular rod 303 and the conduit 701 to rotate. The conduit 701 can drive the distribution cylinder 8 to rotate, which in turn drives the spraying mechanism 9 to rotate. According to usage requirements, the rotating shaft 111 in the adjusting mechanism 11 rotates in the second mechanical seal 112, causing the rotating shaft 111 to drive the cylinder 113 to rotate. This achieves the effect of adjusting the overlapping area of ​​the through hole 114 on the side wall of the cylinder 113 and the through hole 114 on the side wall of the distribution box 901, which is to adjust the water flow rate into the distribution box 901, thereby adjusting the flow rate of the spray head 902. The distribution box 901... Water is sprayed out through nozzle 902. After use, the conical cylinder 5 loses its upward water thrust, causing the telescopic spring 14 to move downwards on the conical cylinder 5. This causes the conical cylinder 5 to retract the liquid distribution cylinder 8 into the sealing ring 13, sealing the nozzle 902 within the inner wall of the sealing ring 13. This enhances the filtration function of the telescopic nozzle and improves the cleaning function of the filter mechanism 3, making it less prone to clogging, extending its service life. The filter mechanism 3 is also easy to disassemble and clean, effectively preventing impurities from clogging the nozzle 902. The telescopic height and water output of the nozzle 902 can be adjusted to meet various environmental spraying needs, making it highly practical. The liquid distribution cylinder 8 retracts into the sealing ring 13, effectively preventing soil from entering, and the entire telescopic nozzle device is easy to disassemble and maintain.

[0039] In summary, this anti-clogging buried telescopic sprinkler head device enhances the filtration function of the telescopic sprinkler head through the filter mechanism 3, effectively preventing impurities from clogging the sprinkler head 902. It can adjust the height and water output of the sprinkler head 902, thereby meeting the spraying needs of various environments. It is highly practical, and the liquid distribution cylinder 8 retracts into the sealing ring 13, effectively preventing soil from entering. The overall telescopic sprinkler head device is easy to disassemble and maintain.
