[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] First Embodiment

[0043] See Figures 1-6 A water outlet device, wherein the water outlet device is a handheld shower head 210, an overhead shower head, a spray gun 220, etc.; the water outlet device includes a housing 230 and a water distribution body located inside the housing 230, and the water outlet device also includes a plurality of water outlet holes 250, wherein the water distribution body is used to connect to an external water source and guide water to the water outlet holes 250 for spraying.

[0044] The water outlet device further includes a water outlet switching mechanism 10, which is arranged on the water distribution body. The water outlet switching mechanism 10 includes a main body component 1 and a switching component 2. The main body component 1 includes a first main body 11 and a second main body 12. The switching component 2 includes one or more rotating body structures 21. In this embodiment, the rotating body structure 21 is a sphere. In some simpler alternatives, the rotating body structure 21 is a cylinder, a spindle, or an ellipsoid, etc. The rotating body structure 21 is rolled between the first main body 11 and the second main body 12 so that the first main body 11 can rotate relative to the second main body 12. The main body component 1 also includes at least one water inlet channel 13 and at least one water outlet channel 14. When the first main body 11 and the second main body 12 rotate relative to each other to a predetermined rotation position, the rotating body structure 21 blocks the water inlet channel 13 and / or the water outlet channel 14 so that the water inlet channel 13 is connected to or not connected to the water outlet channel 14.

[0045] In this embodiment, the first main body 11 is fixedly connected to the water distribution body of the water outlet device, and the first main body 11 is cylindrical. The second main body 12 is rotatably connected inside the first main body 11, and a receiving space 15 is formed between the first main body 11 and the second main body 12. The rotating body structure 21 is arranged inside the receiving space 15. The receiving space 15 is connected to the water inlet channel 13 and the water outlet channel 14 respectively. When the water outlet switching mechanism 10 is filled with water, the receiving space 15 is filled with water to make the rotation between the first main body 11 and the second main body 12 smoother and less strenuous.

[0046] In this embodiment, the upper end of the first body 11 includes an external thread for fixed connection with the water distribution body. The lower end of the first body 11 includes a lower opening 111. The second body 12 is inserted into the first body 11 from bottom to top through the lower opening 111. The upper end of the first body 11 includes an upper opening 112. The upper end of the second body 12 corresponds to the upper opening 112. A recess 121 is formed at the upper end of the second body 12. The peripheral wall of the recess 121 includes one or more through holes 122 connecting to the receiving space 15. The recess 121 and the through holes 122 define the water inlet channel 13, that is, the second body 12 includes the water inlet channel 13. The lower end of the second body 12 includes a rotating disk seat 123. The rotating disk seat 123 is fitted into the lower opening 111 of the first body 11 so that the rotating disk seat 123 can rotate relative to the lower opening 111 of the first body 11. The lower part of the rotating disk base 123 includes multiple outlets 1231, and the middle waist of the second main body 12 includes an annular groove 124. Multiple inlets 1241 are included above the annular groove 124, and the multiple inlets 1241 are respectively connected to the multiple outlets 1231 to define multiple water outlet channels 14. The rotating body structure 21 rolls correspondingly above the annular groove 124 to block the inlets 1241, thereby blocking one or more of the water outlet channels 14. That is, the main body component 1 includes at least two water outlet channels 14; when the first main body 11 and the second main body 12 rotate relative to each other to different predetermined rotation positions, the water inlet channel 13 is connected to one of the water outlet channels 14, and the rotating body structure 21 correspondingly blocks the inlets 1241 of the remaining water outlet channels 14. In this embodiment, the rotating body structure 21 can be made of rubber, which can increase the sealing performance.

[0047] The inner wall of the first body 11 includes a positioning portion 113 for positioning the rotating body structure 21. The positioning portion 113 includes one or more positioning recesses 1131 corresponding to the number of rotating body structures 21. In the case of multiple positioning recesses 1131, the positioning recesses 1131 are arranged at circumferential intervals along the first body 11, and the rotating body structure 21 rolls within the positioning recesses 1131 so that the position of the rotating body structure 21 relative to the first body 11 remains unchanged. That is, in this embodiment, the rotating body structure is arranged between the inner and outer peripheral walls of the first body and the second body.

[0048] The water outlet switching mechanism 10 further includes a positioning mechanism 3; the positioning mechanism 3 is connected between the first body 11 and the second body 12; the positioning mechanism 3 is used to rotate the first body 11 and the second body 12 relative to each other to one of the predetermined rotation positions; the positioning mechanism 3 includes a plurality of positioning grooves 31 located on one of the first body 11 and the second body 12, and the positioning mechanism 3 also includes a positioning protrusion mechanism 32 located on the other of the first body 11 and the second body 12. When the first body 11 and the second body 12 rotate relative to each other, the positioning protrusion mechanism 32 is correspondingly embedded in one of the positioning grooves 31 to correspond to one of the predetermined rotation positions. In this embodiment, the inner wall of the first body 11 includes a plurality of positioning grooves 31, and the outer peripheral wall of the second body 12 is provided with the positioning protrusion mechanism 32. The positioning protrusion mechanism 32 includes a spring and a ball 322 pushed by the spring. The ball 322 is correspondingly embedded in one of the positioning grooves 31 to achieve the positioning of the predetermined rotation position. In this embodiment, four positioning grooves 31 are provided, that is, four predetermined rotation positions are provided.

[0049] In this embodiment, the switching component 2 includes six rotating structures 21, and the annular groove 124 includes six spaced-apart inlets 1241. In this embodiment, every two inlets 1241 arranged at 180-degree intervals are connected to an outlet 1231 to form a water outlet channel 14. That is, this embodiment includes three water outlet channels 14.

[0050] When the second main body 12 rotates relative to the first main body 11, the ball 322 of the positioning protrusion structure is embedded in one of the positioning grooves 31 to determine one of the predetermined rotation positions. The second main body 12 rotates relative to the first main body 11 to be in the first predetermined rotation position, the second predetermined rotation position, the third predetermined rotation position, and the fourth predetermined rotation position in sequence. When it is in the first predetermined rotation position, all six rotating structures 21 simultaneously block the six inlets 1241, and the water outlet device is in the water-off state. When it rotates at a specific angle (e.g., 30 degrees, 45 degrees, etc.) and enters the second predetermined rotation position, the ball 322 of the positioning protrusion structure is embedded in the next positioning groove 31. At this time, the movement of the six rotating structures 21 relative to the second main body 12 causes one pair of inlets 1241 to be unblocked, and the first water outlet channel 14 of the three water outlet channels 14 is connected to the water inlet channel 13. Similarly, the second water outlet channel 14 and the third water outlet channel 14 can be connected to the water inlet channel 13 in sequence, and the remaining water outlet channels 14 are blocked simultaneously.

[0051] In some simpler alternatives, the main body component 1 includes at least two water inlet channels 13; when the first main body 11 and the second main body 12 rotate relative to each other to different predetermined rotation positions, the water outlet channel 14 is connected to one of the water inlet channels 13, and the rotating body structure 21 correspondingly blocks the inlets 1241 of the remaining water inlet channels 13. That is, the main body component 1 may include multiple water inlet channels 13, each water inlet channel 13 can output different types of water, such as tap water, purified water, soda water, etc., and at different predetermined rotation positions, the water outlet channel 14 can be connected to different water inlet channels 13 to achieve the effect of outputting different types of water.

During assembly, the rotating body structure 21 is clamped between the abutting cylinder 125 and the annular groove 124.

The rotating body structure 21 moves within the annular groove 124. That is, in this embodiment, the rotating body structure is arranged between the inner and outer peripheral walls of the first and second bodies.
