[0002] The sprinkler is the most important part of the sprinkler system. It sprays the pressurized water into the air, which is scattered into small water droplets and evenly scattered on the irrigation area controlled by it. It is also called a sprinkler. Its function is to convert the pressure energy of the water flow into kinetic energy, spray it into the air to form raindrops, and evenly distribute them to the irrigation area to irrigate the lawn. The sprinkler can be installed on a fixed or mobile pipeline, on the water pipe of the sprayer group truss, and on the traction frame of the winch sprinkler, and it can form a complete sprinkler or sprinkler system with matching machines and pumps. The performance of the sprinkler and whether it is used properly will play a decisive role in the spraying quality, economy and working reliability of the entire sprinkler system or sprinkler.

[0003] Existing sprinklers are directly connected to the water supply pipe. Although the water spraying is fast and smooth, after the sprinkler stops, a large amount of water remains in the water supply pipe, so the sprinkler will still flow water. In the scene of large-scale mechanized irrigation, the amount of water used for irrigation cannot be accurately controlled, and unnecessary waste of water resources will occur, resulting in poor irrigation effect and high irrigation cost. In addition, existing sprinklers all use a single sprinkler for irrigation, and the irrigation method is relatively single, which cannot be used in environments with different periods and different irrigation amounts.

[0028] Working principle: water flows through the water inlet connecting tube 112 into the buffer chamber 117. When the water flow pressure is large enough, the water flow will push open the anti-overflow top plate 25, so that the water flows through the buffer chamber 117 into the water inlet pipe 116. The water flows through the filter mesh tube 134 in the nozzle connecting tube 132 for filtering, and finally is atomized and sprayed out through the nozzle head 32. When the water flow pressure is insufficient, the anti-overflow top plate 25 is tightly connected to the top of the water outlet tube 113 under the action of the return spring 26, thereby preventing the water from flowing through the buffer chamber 117 into the water outlet pipe 116, thereby achieving an anti-overflow effect. The filter mesh tube 134 provided can effectively filter impurities in the water to prevent impurities in the water from clogging the nozzle head 32. The nozzle head 32 can expand the area of ​​water spraying to ensure the efficiency of the spray.
