[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model discloses an anti-clogging irrigation sprinkler head, which includes a pipe 1 and a three-way diverter valve 2. Both ends of the pipe 1 are provided with threaded portions 10 to facilitate connection with other water conservancy facilities or water sources. One end of the three-way diverter valve 2 is connected to the pipe 1 through a first connecting pipe 3. The other two ends of the three-way diverter valve 2 are respectively fixedly connected to a second connecting pipe 4 and a third connecting pipe 5. A fourth connecting pipe 6 is fixedly connected to one side of the second connecting pipe 4. The third connecting pipe 5 is connected to the fourth connecting pipe 6. A sprinkler head 7 is provided at the top of the fourth connecting pipe 6. A filter screen 12 is provided inside the fourth connecting pipe 6, located below the end of the third connecting pipe 5. A valve 9 is also provided on the outside of the second connecting pipe 4.

[0024] During normal irrigation, the three-way diverter valve 2 is controlled to connect the first connecting pipe 3, the three-way diverter valve 2, and the second connecting pipe 4, while the third connecting pipe 5 is disconnected and valve 9 is closed. Water can flow inside the fourth connecting pipe 6 and be sprayed out through the nozzle 7 for irrigation. The filter screen 12 installed inside the fourth connecting pipe 6 is used to filter out impurities and particles in the water flow, preventing the nozzle 7 from clogging. When it is necessary to clean the filter screen 12, the three-way diverter valve 2 is controlled to connect the first connecting pipe 3, the three-way diverter valve 2, and the third connecting pipe 5, while the second connecting pipe 4 is disconnected and valve 9 is opened. Water flows through the third connecting pipe 5 to the inside of the fourth connecting pipe 6, and some water flows from above the filter screen 12 into the inside of the second connecting pipe 4. Under the impact of the water flow, the filter screen 12 is backwashed, thus cleaning it. Wastewater is discharged through valve 9. Backwashing effectively removes impurities and particles accumulated on the filter screen 12, extending its service life and reducing replacement frequency due to clogging. Simultaneously, the flushed wastewater and impurities can be smoothly discharged through the open valve 9, preventing the retention and accumulation of contaminants in the irrigation system and further ensuring its clean and efficient operation.

[0025] A mounting plate 14 is fixedly connected to the top side of the nozzle 7. A cover plate 8 is hinged to the top of the mounting plate 14 and located on the top of the nozzle 7. A stop block 15 is also fixedly connected to the top of the mounting plate 14. The stop block 15 is slightly inclined to the side of the cover plate 8.

[0026] When the nozzle 7 is not in use, the cover plate 8 is placed over the opening of the nozzle 7 to protect the opening and prevent debris from clogging the exposed nozzle 7. The freely rotating cover plate 8 can rotate to a vertical position under the impact of water flow, and is limited by the inclined stop block 15, so that the cover plate 8 can rotate freely and close on the nozzle 7 when the impact of water flow is removed.

[0027] To facilitate maintenance and cleaning of the nozzle 7, the nozzle 7 is threaded to the top of the fourth connecting pipe 6. A support ring 11 is fixedly connected to the inner wall of the fourth connecting pipe 6, and the filter screen 12 is attached to the top of the support ring 11. Multiple limiting rods 13 are evenly fixedly connected to the bottom of the nozzle 7, and the bottom of each limiting rod 13 is in contact with the top of the filter screen 12.

[0028] The filter screen 12 is positioned inside the fourth connecting pipe 6 through the cooperation of the support ring 11 and the limiting rod 13. The movable connection method, together with the movable structure of the nozzle 7, facilitates internal cleaning or maintenance, making it more flexible to use.

[0029] Working principle: During normal irrigation, the three-way diverter valve 2 is controlled to connect the first connecting pipe 3, the three-way diverter valve 2, and the second connecting pipe 4, while the third connecting pipe 5 is disconnected and valve 9 is closed. Water can flow inside the fourth connecting pipe 6 and be sprayed out through the nozzle 7 for irrigation. The filter screen 12 installed inside the fourth connecting pipe 6 is used to filter out impurities and particles in the water flow, preventing the nozzle 7 from clogging. When it is necessary to clean the filter screen 12, the three-way diverter valve 2 is controlled to connect the first connecting pipe 3, the three-way diverter valve 2, and the third connecting pipe 5, while the second connecting pipe 4 is disconnected and valve 9 is opened. Water flows through the third connecting pipe 5 to the inside of the fourth connecting pipe 6, and some water flows from above the filter screen 12 into the inside of the second connecting pipe 4. Under the impact of the water flow, the filter screen 12 is backwashed, thus cleaning it. Wastewater is discharged through valve 9. Backwashing effectively removes impurities and particles accumulated on the filter screen 12, extending its service life and reducing replacement frequency due to clogging. Simultaneously, the flushed wastewater and impurities can be smoothly discharged through the open valve 9, preventing the retention and accumulation of contaminants in the irrigation system and further ensuring its clean and efficient operation.
