[0038] The top shower body 1 is provided with a water inlet channel 11 , a mounting cavity 12 , a water passage 13 and a water outlet channel 14 .

[0039] The water inlet channel 11 forms a water inlet joint at the periphery or top of the top shower. Preferably, the water inlet joint adopts a swinging ball head structure, which can flexibly adjust the water outlet direction, and the other end of the water inlet channel 11 is connected to the water inlet of the installation cavity 12.

[0040] The installation cavity 12 is provided with a water hole 15 connected to the water channel 13. There are at least two water outlet channels 14, and the switching component 2 is movably installed at the water outlet end of the water channel 13. The water channel 13 is connected to any water outlet channel 14 through the switching component 2, so that different water splashes can be produced. The hydraulic drive component 3 is movably installed in the installation cavity 12, blocking or opening the water hole 15, and one end faces the water inlet of the installation cavity 12, and the other end is connected to the switching component 2. When in use, water passes through the water inlet channel 11, and the hydraulic drive component 3 is driven by hydraulic power, and drives the switching component 2 to switch the water channel 13 connected to the water outlet channel 14, and open the water hole 15, so as to realize the switching of water outlet of the top spray. When the water inlet channel 11 stops flowing, the hydraulic drive component 3 resets and blocks the water hole 15.

[0041] In one embodiment, the water inlet end of each of the water outlet channels 14 forms an annularly distributed water inlet hole 16 inside the top shower body 1. The switching assembly 2 includes a water divider plate 21, which is rotatably installed and covers each of the water inlet holes 16, and the water divider plate 21 is provided with a water divider hole 211. The hydraulic drive assembly 3 drives the water divider plate 21 to rotate through hydraulic action, and the water divider hole 211 is sequentially connected with each of the water inlet holes 16, thereby switching the water outlet state of the top shower in sequence. In addition, in order to simplify the structure and reduce the difficulty of forming the installation cavity 12, a coaxial rotating disk 22 is provided on the top of the water divider plate 21, and the rotating disk 22 forms a partition between the installation cavity 12 and the water passage 13, and a Y-shaped sealing ring is provided between the rotating disk 22 and the peripheral wall of the installation cavity 12.

[0042] On the basis of the above-mentioned embodiment, a pressing and rotating structure is adopted between the hydraulic driving assembly 3 and the water diversion plate 21 . Preferably, the pressing and rotating structure includes a guide groove 231 and a driving block 31 .

[0043] Specifically, a coaxial rotating shaft 23 is provided at the top of the water diversion plate 21, and the guide groove 231 includes a plurality of inclined grooves 2311 and vertical grooves 2312, and the inclined grooves 2311 and vertical grooves 2312 are sequentially connected end to end and arranged at the periphery of the rotating shaft 23 to form a complete and cyclic guide groove 231. In addition, the top of the inclined groove 2311 is located at the top of the top of the vertical groove 2312, and is shallower than the top of the vertical groove 2312, forming a first non-return step 2313.
