In this embodiment, one end of the spray rod 2 is the front end of the spray rod 2, that is, one end of the spray rod 2 for discharging water is provided with a nozzle 5. The limiting component is positioned at the front part of the fixed part 1; the limiting component is an arc-shaped gland 121 positioned on the spray rod 2, and the arc-shaped gland 121 is specifically arranged in front of the guide rail 12 of the fixed part 1.

In this embodiment, the waterway control portion has a water inlet 411, and the waterway control portion has two control states, wherein one state is that the water inlet 411 is communicated with the self-cleaning water outlet structure 21 and the flushing waterway 22, and the other state is that the water inlet 411 is communicated with the flushing waterway 22.

In this embodiment, the waterway control portion includes a waterway switching block 4, the waterway switching block 4 has the water inlet 411, a first water outlet 412 communicating with the water inlet 411, and a second water outlet 413 communicating with the water inlet 411, and the second water outlet 413 is connected to the flushing waterway 22; the waterway switching block 4 is slidably attached to the spray bar 2 in the sliding direction of the spray bar 2, and by sliding relative to the spray bar 2, the first water outlet 412 is staggered or communicated with the water inlet hole 211 correspondingly.

In this embodiment, the fixed portion 1 has a first limiting portion and a second limiting portion, and after the waterway switching block 4 slides along with the spray rod 2 in the extending direction until stopped by the first limiting portion, the first water outlet 412 is staggered with the water inlet hole 211 along with the spray rod 2 continuing to slide in the extending direction; after the waterway switching block 4 slides along the spray rod 2 in the retraction direction until being stopped by the second limit part, the first water outlet 412 and the water inlet 211 are restored to the corresponding connection state as the spray rod 2 continues to slide along the retraction direction. The cross-sectional area of the water inlet hole 211 is larger than that of the flushing waterway, so that the water inlet amount of the water inlet hole 211 is larger than that of the flushing waterway 22 when the first water outlet 412 is connected to the water inlet hole 211. In order to avoid the influence on the connection reliability between the second water outlet 413 and the flushing waterway 22 when the waterway switching block 4 slides relative to the spray bar 2, the flushing waterway 22 may be implemented by using a flexible hose.

In this embodiment, the waterway switching block 4 is sleeved with a sealing gasket 42 at the first water outlet 412, as shown in fig. 6, the sealing gasket 42 has an elastically deformable deformation portion 421, and the deformation portion 421 is provided with a water through hole 422 communicated with the first water outlet 412 and an annular water tank 423 surrounding the water through hole 422; the deformation portion 421 of the gasket 42 is attached to the wall surface of the water inlet 211 of the nozzle bar 2. The deformation part 421 of the sealing gasket 42 is provided with a ring of annular protrusion 424 protruding outwards, the annular protrusion 424 is coaxial with the water through hole 422, and the deformation part 421 is attached to the wall surface of the water inlet hole 211 of the spray rod 2 through the annular protrusion 424. The water path switching block 4 is in the water inlet process, water impacts the annular water channel 423 of the sealing gasket 42, so that the deformation part 421 of the sealing gasket 42 is expanded outwards under the impact of water, and the wall surface where the water inlet hole 211 of the spray rod 2 is located is compressed, when the water pressure is high, the outward expansion degree of the deformation part 421 of the sealing gasket 42 is high, the annular protrusion 424 of the sealing gasket 42 is attached to the wall surface where the water inlet hole 211 of the spray rod 2 is located tightly, and the water seepage phenomenon caused by the fact that the water pressure is too high is prevented.

In this embodiment, as shown in fig. 5 and 6, the waterway switching block 4 specifically includes a fixed support 43, a three-way pipe 41, and the sealing gasket 42, wherein three ends of the three-way pipe 41 correspond to the water inlet 411, the first water outlet 412, and the second water outlet 413, the three-way pipe is connected to the fixed support 43, and the sealing gasket 42 is sleeved on one end of the three-way pipe 41 where the first water outlet 412 is located. In order to make the water output of the first water outlet 412 greater than the water output of the second water outlet 413 when the first water outlet 412 is connected to the water inlet 211, a baffle 414 is disposed inside the three-way pipe 41, and the inlet of the water outlet passage where the second water outlet 413 is located inside the three-way pipe 41 is made smaller by the baffle 414.
