[0028] As Figures 1-6 The utility model discloses a spray head structure for garden afforestation irrigation, aims at providing a kind of spray head with stable structure, even water spraying and effectively filtering impurity.The spray head structure mainly includes spray head main part 1 and nozzle 2, when assembling, one end of spray head main part 1 is equipped with opening part 101, nozzle 2 is installed on opening part 101 by the way of rotation, and it is formed with a sealed cavity 3 with spray head main part 1, the cavity 3 is the position of water storage and flowing water in nozzle head.

[0029] The one end of the nozzle body 1 is coaxially provided with an inner ring body 102, which extends to the one end of the nozzle 2 and is located in the cavity 3. The main function of the inner ring body 102 is to serve as part of the water flow channel, and it can also be used to fix the filter cover 4. The inside of the nozzle 2 is coaxially provided with an outer ring body 201, which extends to the one end of the nozzle body 1 and is located in the cavity 3. In terms of structural distribution, the outer ring body 201 is distributed on the periphery of the inner ring body 102, and the extended end forms a staggered structure, so that the water flow channel in the cavity 3 forms a repeated bending structure, which helps to improve the water pressure.

[0030] The nozzle body 1 is provided with a water flow channel 103 for water injection, which is communicated with the cavity 3 through the inner side of the inner ring body 102. The water flow enters the cavity 3 through the water flow channel 103, then passes through the gap between the outer ring body 201 and the inner ring body 102, and finally is sprayed out from the water outlet 202. In order not to affect the water spraying of the water outlet 202, the height of the opening part 101 should be less than the internal depth of the nozzle 2, so as to avoid that the opening part 101 blocks the water outlet 202 after installation.

[0031] A plurality of protruding clamping strips 105 are arranged on the inner wall of the opening part 101. The clamping strips 105 are uniformly distributed on the inner wall of the opening part 101 and extend along the central axis of the opening part 101. The clamping strips 105 can uniformly disperse the direction of water flow, so that the water flow uniformly flows to the corresponding water outlet 202, improving the uniformity of water spraying.

[0032] The outer side of the one end of the nozzle 2 away from the nozzle body 1 is provided with a plurality of water outlets 202 for water spraying. The water outlets 202 are communicated with the cavity 3 and are uniformly distributed on the periphery of the outer ring body 201, so as to ensure that the sprayed water flow can uniformly cover the irrigation area.

[0033] In order to better connect the nozzle body 1 and the nozzle 2, the outer side of the opening part 101 is provided with a first threaded body 104, and the inner wall of the nozzle 2 is provided with a second threaded body 203 matched with the first threaded body 104.

The design of the connecting part 106 facilitates the connection of the nozzle with the water pipe of the irrigation system, so as to realize the input of water flow.

[0035] In addition, in order to prevent the water outlet 202 from being blocked, a filter screen cover 4 for filtering is additionally arranged in the cavity 3. Specifically, the filter screen cover 4 is arranged in the nozzle body 1 and has an open end, and the side surface of the filter screen cover 4 is fixedly arranged against the inner wall of the inner ring body 102. The main function of the filter screen cover 4 is to filter the impurities in the water, so as to prevent the impurities from blocking the water outlet 202 or affecting the uniformity of the water spray.

[0036] The filter screen cover 4 is arranged against the inner wall of the inner ring body 102 and has a circular frame 401 arranged at the open end of the filter screen cover 4 and distributed around the water flow channel 103. The circular frame 401 is arranged to increase the stability of the filter screen cover 4 and prevent the filter screen cover 4 from being deformed or falling off under the high-pressure water flow. After the filter screen cover 4 is arranged, the end of the filter screen cover 4 away from the water outlet is pushed out of the inner ring body 102 and contacts the nozzle 2, so as to prevent the filter screen cover 4 from falling off along the direction of the water flow.

[0037] Compared with the prior art, the nozzle provided by the technical scheme can extend the water flow path by additionally arranging the inner ring body 102 and the outer ring body 201 extending and staggered in the cavity, so as to form a repeatedly bent structure, which can prolong the water flow path and help to increase the water pressure, so as to form a better water spray effect. In addition, the filter screen cover 4 for filtering the impurities in the water is arranged in the water flow cavity 3, so as to effectively prevent the water outlet 202 from being blocked and prolong the service life of the nozzle.
