By adding auxiliary agents, the application range of the sprinkler is further improved; however, since many agents will cause certain corrosion to the transmission pipelines and pressure equipment of the sprinkler during the sprinkler irrigation process, these agents cannot be added to the sprinkler water before sprinkler irrigation. However, the sprinkler irrigation operation is performed by mixing the two fluids with each other during the sprinkler irrigation process. During the operation, due to the excessively fast flow rate of the water during the sprinkler irrigation process, the two fluids cannot be fully mixed, thereby affecting the sprinkler irrigation effect.

[0028] The utility model provides a sprinkler head for a sprinkler.

[0029] A sprinkler nozzle includes an outer tube 2, one end of which is provided with a water inlet pipe 1, the other end of the outer tube 2 is provided with a liquid outlet pipe 3, an inner tube 4 is sleeved inside the outer tube 2, and a baffle 5 is provided at the end of the inner tube 4 close to the water inlet pipe 1. A plurality of baffle rings 6 are provided in the annular space formed by the outer tube 2 and the inner tube 4. The baffle rings 6 are arranged at intervals along the axial direction of the outer tube 2, and buffer units 8 are formed between adjacent baffle rings 6. The buffer units 8 form a buffer zone (not marked), and the buffer units 8 are connected in sequence. The water inlet pipe 1, the buffer zone, the cavity of the inner tube 4 and the liquid outlet pipe 3 are connected in sequence. The buffer unit 8 close to the water inlet pipe 1 is connected to an auxiliary agent addition pipe 16.

[0030] In the technical solution proposed in the present application, the auxiliary agent enters the buffer unit 8 through the auxiliary agent adding pipe 16, and the sprinkler water enters the buffer unit 8 under the obstruction of the baffle 5. The sprinkler water and the auxiliary agent are mixed in multiple buffer units 8 in the buffer zone, which extends the mixing time and allows the two fluids to be fully mixed. The obtained mixed liquid is discharged through the cavity of the inner cylinder 4 and the liquid outlet pipe 3. Under the action of the baffle 5, the mixed liquid will not flow into the water inlet pipe 1, solving the technical problem that the pipelines and pressure equipment of the sprinkler are easily corroded by the auxiliary agent.

[0031] The sprinkler head also includes a buffer tube 9 with an open end. Buffer tube 9 is located within inner tube 4 and is provided with a plurality of first through-holes 10. The open end of buffer tube 9 is connected to the end of outer tube 2 provided with liquid outlet tube 3, thereby communicating with liquid outlet tube 3. In a specific embodiment, the buffer tube 9 has a plurality of first through-holes 10 on both the closed end and the side of the buffer tube 9. The arrangement of the buffer tube 9 and the plurality of first through-holes 10 allows the two fluids to further mix within the inner cavity of inner tube 4, resulting in a more uniform mixing of the two fluids.

[0032] An end cap 11 is provided at one end of the outer tube 2 connected to the liquid outlet pipe 3. The end cap 11 is detachably connected to the outer tube 2.

The outer circumferential surface of the connecting tube 13 is threadedly connected to the inner circumferential surface of the inner tube 4. In a specific embodiment, one end of the connecting tube 13 is connected to the end cap 11 by bolts (not shown) and studs (not shown). The other end of the connecting tube 13 is integrally formed with the baffle 5. When it is necessary to mix two fluids, the connecting tube 13 is connected to the end cap 11 and the connecting tube 13 is threadedly connected to the inner tube 4. When it is not necessary to mix the two fluids, the end cap 11, the connecting tube 13 and the baffle 5 are rotated out as a whole, and the end cap 11 and the connecting tube 13 are disassembled.

[0033] The open end of the buffer tube 9 is detachably connected to the end cover 11. This structure facilitates flushing and replacement of the buffer tube 9.

[0034] The inner tube 4 is open at both ends, while the outer tube 2 is open at one end. The open end of the outer tube 2 is connected to the end cap 11. One end of the inner tube 4 contacts the end cap 11, and the other end of the inner tube 4 contacts the closed end of the outer tube 2. The inner circumferential surfaces of the plurality of retaining rings 6 are fixedly connected to the outer circumferential surface of the inner tube 4, and the outer circumferential surfaces of the plurality of retaining rings 6 are respectively fitted with the inner circumferential surface of the outer tube 2. The plurality of retaining rings 6 are arranged on the outer circumferential surface of the inner tube 4, which facilitates their installation. When assembling the inner tube 4, outer tube 2, and the plurality of retaining rings 6, it is only necessary to place the inner tube 4 and the plurality of retaining rings 6 as a whole into the outer tube 2, which is quick and efficient.

[0035] Several baffle rings 6 are respectively provided with second through holes 7, and the second through holes 7 of adjacent baffle rings 6 are staggered. This structure can further prolong the flow time of the two fluids in the buffer zone, further prolong the mixing time, and ensure the mixing effect.

[0036] A third through hole 14 is provided at one end of the inner cylinder 4 near the water inlet pipe 1. The third through hole 14 is located between the water inlet pipe 1 and the baffle 5. The third through hole 14 is also located between the water inlet pipe 1 and the baffle ring 6 closest to the water inlet pipe 1. The function of the third through hole 14 is to connect the water inlet pipe 1 and the buffer zone.

[0037] A fourth through hole 15 is provided at the end of the inner tube 4 away from the water inlet pipe 1. The fourth through hole 15 extends through the inner tube 4 and the connecting tube 13. The fourth through hole 15 is located between the end cap 11 and the retaining ring 6 farthest from the water inlet pipe 1. The function of the fourth through hole 15 is to connect the buffer zone with the inner cavity of the inner tube 4.

[0038] In order to control the auxiliary agent, the auxiliary agent adding pipe 16 is provided with a valve 17. In order to ensure the sprinkler irrigation effect, the liquid outlet pipe 3 is connected to a spraying member 12.
