When the ring assembly 4 is turned, the linkage member 5 moves along the adjustment track 41 to drive the rotating shaft 3 to move along its axial direction.

[0022] Specifically, the connecting portion is a tubular structure. In order to facilitate the installation between the dial ring assembly 4 and the connecting portion 22 and the setting of the linkage member 5, the dial ring assembly 4 includes a dial ring 43 and a track ring 42 which are sleeved on the rotating shaft 3, the dial ring 43 is provided with a track groove 431, the track groove 431 is provided on the inner wall of the dial ring 43, the outer wall of the dial ring 43 is provided with a paddle portion 432 for assisting manual shifting, the track ring 42 is provided with a track block 421 corresponding to the track groove 431, and the track block 421 cooperates with the track groove 431 to form the adjustment track 41. The design formed by the splicing of the adjustment track 41 can facilitate the linkage member 5 to be placed in the adjustment track 41 while being installed on the rotating shaft 3. Preferably, the dial ring assembly 4 also includes an auxiliary support ring 44 sleeved on the rotating shaft 3, and the auxiliary support ring 44 and the track ring 42 are respectively provided at two ends in the dial ring 43. Correspondingly, the auxiliary support ring 44 and the track ring 42 are provided with protrusions 45 for linkage, and the inner wall of the shift ring 43 is provided with grooves 46 corresponding to the protrusions 45, so that the shift ring 43, the track ring 42 and the auxiliary support ring 44 can rotate synchronously.

[0023] Moreover, the rotating shaft 3 is provided with a plug hole 33 for installing the linkage member 5, the connecting portion 22 is provided with a stroke hole 221 for limiting the axial movement of the rotating shaft 3, and one end of the linkage member 5 passes through the stroke hole 221 and is inserted into the adjustment track 41. The bottom of the linkage member 5 is adapted to the plug hole 33, and the part thereof inserted into the adjustment track 41 is cylindrical to reduce its movement resistance in the adjustment track 41.

[0024] The handle 1 is provided with a shaft groove 12 adapted to the shaft 3, and the water inlet 11 is provided on the side wall of the shaft groove 12. Therefore, the arrangement of the travel hole 221 can also prevent the water inlet 11 and the adjustment hole 32 from being misaligned along the rotation direction of the shaft 3.

[0025] In order to better adapt to the user's adjustment habits, see Figure 4, the adjustment track 41 includes two mirror-imaged graded tracks 41a, that is, the water volume adjustment effect can be obtained regardless of whether the user rotates the dial ring 43 clockwise or counterclockwise. Accordingly, in order to ensure that the adjustment range of the dial ring assembly 4 can cover the adjustment range between the water inlet 11 and the adjustment hole 32. The projection length of the graded guide rail 41a on the plane where the axis of the rotating shaft 3 is located is the maximum adjustment length; the water inlet 11 is a strip-shaped opening, and along the axial direction of the rotating shaft 3, its maximum opening length is the maximum flow length, and the maximum adjustment length is greater than the maximum flow length. Preferably, the adjustment track is V-shaped.

[0026] The rotating shaft 3 is provided with two positioning rings 34, and the handle 1 and the connecting portion 22 are both provided with limiting step surfaces 6 corresponding to the positioning rings 34, so that the rotating shaft 3 is limited to a preset area in the connecting portion 22 during initial installation. In addition, in order to improve the sealing between the handle 1 and the connecting portion 22 and prevent water from seeping out of the area, the positioning ring 34 is also provided with a sealing groove, and the sealing groove is provided with a sealing ring, and the sealing ring is preferably a V-shaped sealing ring.

[0027] See also Figure 5 The shower head 2 includes a shower body 23 and a rotating surface cover 24 .

The channel selection seat 242 is provided with a plurality of independent water outlet chambers 2421. The water outlet chambers 2421 are provided with channel openings 2422 adapted to the water inlet 21. The water splash cover 241 is provided with water outlet hole groups 2411 corresponding to each of the water outlet chambers 2421. The water outlet chambers 2421 are arranged in a multi-layer ring shape in the channel selection seat 242. Accordingly, the number of water outlet holes of the water outlet hole group 2411 connected to each of the water outlet chambers 2421 is different. Preferably, the number of the connected water outlet holes of the water outlet chamber 2421 gradually increases from the inside to the outside.

[0029] Furthermore, in order to allow the shower user to have a better shower feeling, the channel selection seat 242 is provided with a water outlet cavity 2421 corresponding to the rotating shaft seat 25, that is, the water outlet cavity located at the center. For the convenience of description, the water outlet cavity is a functional cavity 7, and a water outlet core 71 and a rotating member 72 are provided in the functional cavity 7. The water outlet core 71 is provided with a water spray hole 711 for use, and the water spray hole 711 is connected to the functional cavity 7. The rotating member 72 is provided with a water retaining portion 721 for shielding the water spray hole. Therefore, when the rotating member 72 rotates, the water retaining portion 721 and the water spray hole 711 will frequently switch between the two states of opening and closing, so that the ejected water flow has a burst of impact feeling, so as to achieve a massage effect.

[0030] Furthermore, in order to enable the rotating member 72 to rotate by the power of the water flow itself, the functional chamber 7 is provided with a lateral channel 73 for spraying water flow to the water retaining portion 721, and the lateral channel 73 is connected to the channel opening 2422. Preferably, the water retaining portion 721 is a sheet-like structure, and its thickness is consistent with the width of the water spray hole 711. More preferably, the rotating member 72 is an impeller.
