[0001] The invention relates to the technical field of agricultural irrigation, in particular to a nozzle with a cleaning function. Background Art

[0002] With the development of agricultural technology and the increasing scarcity of water resources, traditional artificial irrigation methods are inefficient, resulting in serious waste of water resources. Efficient and precise irrigation technologies, such as sprinkler irrigation and drip irrigation, have gradually become the development direction of water-saving technologies. Adjustable irrigation sprinklers are a type of spraying device that can adjust the spraying range. They usually contain one or more movable or deformable parts to adjust the spraying characteristics according to different application requirements. For example, in some adjustable sprinkler designs, the sprinkler body changes the spraying channel by rotating the connected adjustment block, thereby achieving different coverage ranges to meet specific irrigation or cleaning needs.

[0003] The Chinese patent with application number CN118542218B discloses a water-saving and uniform drip irrigation device for sea buckthorn planting, including a through pipe connector, a water outlet regulating valve core rotatably connected in the pipe connector, a hollow drip irrigation frame is provided on the side of the pipe connector, a water outlet is provided at the extended end of the drip irrigation frame, an opening and closing member is longitudinally rotatably connected to the middle of the drip irrigation frame, a driving member is longitudinally rotatably connected to the drip irrigation frame, the driving member drives the opening and closing member through a first intermediate rod, one end of the first intermediate rod is rotatably connected to the lower end of the opening and closing member and the other end is rotatably connected to the lower end of the driving member, the lower end surface of the extended end of the drip irrigation frame is located below the water outlet and is laterally slidably connected to a water spray range adjusting rod, the water spray range adjusting rod is connected to the side of the opening and closing member through a second intermediate rod, the rotation of the opening and closing member will adjust the extended length of the water spray range adjusting rod through the second intermediate rod, the size of the opening during water spraying is adjusted according to the extended length of the water spray range adjusting rod, thereby adjusting the range of the landing point formed during water spraying.

[0004] Although such a setting can adjust the spraying range, there may be silt and impurities in the water flow connected through the external water pipe. When the silt and impurities pass through the nozzle, they will be deposited inside, causing the nozzle to be blocked. Therefore, the water flow needs to be filtered during irrigation to ensure the normal operation of the irrigation nozzle. At the same time, a corresponding cleaning structure needs to be set inside the nozzle to facilitate the cleaning of the filtered objects, thereby reducing the frequency of disassembly and maintenance.
