[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] A shower faucet is disclosed for connection to a handheld showerhead and an overhead showerhead. The shower faucet includes a lower water outlet with the water flow direction pointing downwards. The handheld showerhead is connected to the shower faucet via a hose, and the overhead showerhead is connected to the shower faucet via a corresponding pipe. The shower faucet includes a faucet body and a thermostatic valve assembly disposed on the faucet body. The faucet body is connected to both hot and cold water, which flow to the thermostatic valve assembly to form a mixed water solution at a constant temperature. The shower faucet also includes a water distribution mechanism that receives the mixed water and can be connected to the lower water outlet of the handheld showerhead, the overhead showerhead, and the shower faucet. The water distribution mechanism controls the flow of the mixed water to one of these three lower water outlets.

[0025] SeeFigures 1-6 In this embodiment, the water distribution mechanism includes a switching body 1 and a switching mechanism 2. The switching body 1 includes an inlet channel 11, a first valve chamber 12, a second valve chamber 13, a first outlet channel 14, a second outlet channel 15, and a third outlet channel 16. The inlet channel 11, the first outlet channel 14, and the second valve chamber 13 are respectively connected to the first valve chamber 12, and the second outlet channel 15 and the third outlet channel 16 are respectively connected to the second valve chamber 13. In this embodiment, a connecting channel 17 is also provided between the first valve chamber 12 and the second valve chamber 13. In some simpler replacements, the connecting channel 17 may not be provided.

[0026] In this embodiment, the first water outlet channel 14 is connected to the lower water outlet, the second water outlet channel 15 is connected to the handheld shower head, and the third water outlet channel 16 is connected to the overhead shower head.

[0027] The switching body 1 has a columnar structure, and the water distribution mechanism also includes a housing 3 covering the switching body 1. The switching body 1 includes two connectors 18 protruding from the housing 3. Referring to the figure, the connector 18 located at the lower end of the switching body 1 connects to the water inlet channel 11, and the connector 18 located at the upper end of the switching body 1 connects to the overhead shower head. The outer peripheral wall of the connector 18 includes external threads to facilitate connection to other components.

[0028] The water inlet channel 11 is connected to mixed water. The first valve chamber 12 and the second valve chamber 13 are both cylindrical. The switching mechanism 2 includes a first valve body 21, a second valve body 22, a first reset member 23, a control button 24, a first connecting rod 25 and a second connecting rod 26. The first valve body 21 is movably arranged on the first valve chamber 12 to alternately block the first water outlet channel 14 or the second valve chamber 13. The second valve body 22 is movably arranged on the second valve chamber 13 to alternately block the second water outlet channel 15 or the third water outlet channel 16. It should be noted that blocking the second valve chamber 13 here means blocking the connection between the first valve chamber 12 and the second valve chamber 13, that is, blocking the connection channel 17. The first valve body 21 includes a first button 211, a first valve shaft 212, a first sealing ring 213, and a first bushing 214. The shape of the first bushing 214 is adapted to the shape of the first valve cavity 12 so that it can be arranged in the first valve cavity 12. The first sealing ring 213 is sleeved on the first valve shaft 212. The first button 211 is connected to one end of the first valve shaft 212. The first reset member 23 is a spring and its two ends abut against the first valve shaft 212 and the first bushing 214 respectively. The first valve shaft 212 can move in the first bushing 214 to achieve sealing through the first sealing ring 213. The second valve body 22 includes a second button 221, a second valve shaft 222, a second sealing ring 223, and a second bushing 224. The shape of the second bushing 224 is adapted to the shape of the second valve cavity 13 so that it can be arranged inside the second valve cavity 13. The second sealing ring 223 is sleeved on the second valve shaft 222. The second button 221 is connected to one end of the second valve shaft 222. The second valve shaft 222 can move within the second bushing 224 so that it can be sealed by the second sealing ring 223.

[0029] The first connecting rod 25 is pivotally connected between the first valve body 21 and the second valve body 22, and the second connecting rod 26 is pivotally connected between the control button 24 and the second valve body 22. Specifically, the middle component of the first connecting rod 25 is pivotally connected to the switching body 1, and the middle component of the second connecting rod 26 is pivotally connected to the switching body 1. The first end and the second end of the first connecting rod 25 are movably connected to the first valve body 21 and the second valve body 22, respectively, and the first end and the second end of the second connecting rod 26 are movably connected to the second valve body 22 and the control button 24, respectively. In this embodiment, the first end of the first connecting rod 25 is movably connected to the first valve shaft 212, the second end of the first connecting rod 25 is movably connected to the second valve shaft 222, the first end of the second connecting rod 26 is movably connected to the second valve shaft 222, and the second end of the second connecting rod 26 abuts against the control button 24.

[0030] SeeFigure 4 This indicates that the water distribution mechanism is in its initial state. In this initial state, the first reset member 23 drives the first valve body 21 to keep blocking the second valve chamber 13, and simultaneously drives the second valve body 22 to block the second water outlet channel via the first connecting rod 25. The first sealing ring 213 of the first valve body 21 blocks the inlet of the connecting channel 17, and the second end of the first connecting rod 25 drives the second valve body 22 to move to block the second water outlet channel 15. That is, the second sealing ring 223 of the second valve body 22 blocks the inlet of the second water outlet channel 15. At this time, the water in the inlet channel 11 exits through the first outlet channel 14 at the lower outlet.

[0031] See Figure 5 In the initial state, when the user presses the second button 221, the second valve shaft 222 of the second valve body 22 is pushed to block the third water outlet channel 16. At the same time, the first valve body 21 is moved to block the first water outlet channel 14 via the first connecting rod 25. At this time, water can flow through the inlet channel 11, the first valve chamber 12, the connecting channel 17, the second valve chamber 13, and the second water outlet channel 15 to the handheld shower head. The end of the first valve shaft 212 of the first valve body 21 away from the first button 211 is disc-shaped. When the water flows through the first valve chamber 12, it can generate water pressure on the end of the disc-shaped first valve shaft 212. This water pressure can overcome the elasticity of the first reset member 23. Therefore, the first valve body 21 can maintain the blockage of the first water outlet channel 14 under the action of water pressure. When the water inlet channel 11 is not stopped, the first valve body 21 always keeps the first water outlet channel 14 blocked. When the water inlet channel 11 is stopped, the first reset member 23 can drive the first valve body 21 to keep blocking the second valve chamber 13 and simultaneously drive the second valve body 22 to block the second water outlet channel through the first connecting rod 25. At this time, the water distribution structure is in the initial state again.

[0032] See Figure 6 ,exist Figure 5 In the indicated state, the control button 24 can be pressed by the user to drive the second valve body 22 to block the second water outlet channel 15 via the second linkage 26. Furthermore, the second button 221 can be pressed again to block the second water outlet channel 15. Therefore, the control button 24 and the second valve body 22 can be alternately controlled to alternately block the second water outlet channel 15 or the third water outlet channel 16 via the second linkage 26. In this embodiment, the structure of the second valve shaft 222 is similar to that of the first valve shaft 212. Therefore, the second valve body 22 can also maintain the blockage of the second water outlet channel 15 or the third water outlet channel 16 under water pressure. In non-initial states, the water distribution mechanism can be returned to its initial state by stopping the water inlet channel 11.

[0033] See Figure 2Combination Figures 4-5 The second valve shaft 222 of the second valve body 22 includes a first abutting surface 2221. When the water distribution mechanism is in its initial state, the first abutting surface 2221 abuts against the second end of the first connecting rod 25. The second valve body 22 can be controlled to move so as to drive the second end of the first connecting rod 25 to rotate through the first abutting surface 2221, thereby driving the first valve body 21 to move to block the first water outlet channel 14. The second valve shaft 222 of the second valve body 22 also includes a second abutting surface 2222. The first abutting surface 2221 and the second abutting surface 2222 are arranged at intervals along the moving direction of the second valve body 22. When the control button 24 and the second valve body 22 are alternately controlled to alternately block the second water outlet channel 15 or the third water outlet channel 16, the second end of the first connecting rod 25 moves between the first abutting surface 2221 and the second abutting surface 2222. In this embodiment, the side of the second valve shaft 222 facing the first valve body 21 includes a groove 2223. The groove 2223 defines the first abutment surface 2221 and the second abutment surface 2222 at both ends along the moving direction of the second valve shaft 222. The first abutment surface 2221 allows the second valve body 22 to switch by actuating the first connecting rod 25. The combination of the first abutment surface 2221 and the second abutment surface 2222 allows for a certain amount of movement between the second valve shaft 222 and the first connecting rod 25. When the second valve body 22 alternately blocks the second water outlet channel 15 and the third water outlet channel 16, it does not affect the first valve body 21.

[0034] See Figure 2 Combination Figures 4-6 The second valve shaft 222 of the second valve body 22 further includes a third abutment surface 2224 and a fourth abutment surface 2225 spaced apart along its moving direction; when the water distribution mechanism is in the initial state, the first end of the second connecting rod 26 moves between the third abutment surface 2224 and the fourth abutment surface 2225. Therefore, in the initial state, it is possible to prevent the control button 24 from being activated in conjunction with the second valve shaft 222.

[0035] When the second valve body 22 moves to block the third water outlet channel 16, the first end of the second connecting rod 26 abuts against the third abutment surface 2224. The control button 24 can be pressed to drive the second connecting rod 26 to rotate, so that the first end of the second connecting rod 26 pushes the third abutment surface 2224, thereby moving the second valve body 22 to block the second water outlet channel 15. The third abutment surface 2224 enables the second connecting rod 26 to control the second valve shaft 222.

[0036] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
