[0043] Please refer to Figures 1 to 7 , a shower head with adjustable water outlet angle according to a preferred embodiment of the present invention includes a fixed water outlet body 10, at least one movable water outlet body 20 and an angle adjustment structure 40.

[0044] Among them, the fixed water outlet body 10 has a first water outlet cavity 11 and a first water outlet nozzle 16 communicating with the first water outlet cavity 11. The first water outlet nozzle 16 is arranged on the front surface of the fixed water outlet body 10. The movable water outlet body 20 has a second water outlet cavity 21 and a second water outlet nozzle 23 communicating with the second water outlet cavity 21. The second water outlet nozzle 23 is arranged on the front surface of the movable water outlet body 20. The movable water outlet body 20 and the fixed water outlet body 10 are rotatably connected to each other, and the second water outlet cavity 21 communicates with the first water outlet cavity 11. An angle adjustment structure 40 is arranged between the fixed water outlet body 10 and the movable water outlet body 20 to adjust the angle between the fixed water outlet body 10 and the movable water outlet body 20.

[0045] Please refer to Figure 2 , in this embodiment, the angle adjustment structure 40 includes a first tooth part 41 arranged on the fixed water outlet body 10 and a second tooth part 42 arranged on the movable water outlet body 20. The angle between the fixed water outlet body 10 and the movable water outlet body 20 is adjusted through the engagement of the first tooth part 41 and the second tooth part 42, with a simple structure and reliable function. It can be understood that the angle adjustment structure 40 can also adopt other forms of structures, such as a structure in which a plurality of grooves or protrusions cooperate with each other. When adjusting the angle, the grooves and protrusions cooperate in sequence to position the angle so as to achieve the angle adjustment function.

[0046] In this embodiment, there are two movable water outlet bodies 20, which are respectively located on both sides of the fixed water outlet body 10. A first gear 12 and a second gear 13 with a first tooth part 41 are arranged on the fixed water outlet body 10. The first tooth part 41 on the first gear 12 cooperates with the second tooth part 42 on one of the movable water outlet bodies 20, and the first tooth part 41 on the second gear 13 cooperates with the second tooth part 42 on the other movable water outlet body 20. Specifically, there are two upper and lower second tooth parts 42 on each movable water outlet body 20, and the second tooth parts 42 are formed on the outer side wall of the following movable shaft sleeve 22.

[0047] In order to control the amplitude of relative rotation between the fixed water outlet body 10 and the movable water outlet body 20, in this embodiment, the second tooth part 42 only has partial teeth in the circumferential direction, that is, the second tooth part 42 does not form a complete gear, so that the end part of the second tooth part 42 forms a rotation stopping part 43. When the first tooth part 41 is engaged with the second tooth part 42 to reach the end part of the second tooth part 42, the rotation stopping part 43 restricts the two from continuing to rotate relatively, thereby realizing rotation limit. It can be understood that the rotation stopping part 43 can also be arranged on the fixed water outlet body 10. For example, the first tooth parts 41 on the first gear 12 and the second gear 13 are set to have the same structure with only partial teeth as the second tooth part 42, and the rotation stopping part 43 is formed at the end part of the first tooth part 41. In this way, the relative rotation between the fixed water outlet body 10 and the movable water outlet body 20 can also be restricted. Or, there can also be rotation stopping parts 43 on both the fixed water outlet body 10 and the movable water outlet body 20, and the rotation stopping parts 43 are formed at the end parts of the first tooth part 41 and the second tooth part 42.
