[0031] Reference Figure 1 , Figure 2 and Figure 3 A faucet according to an embodiment of the present invention includes: a housing 1, a water distribution assembly 2, and a valve stem assembly 3; the housing 1 has an inlet channel 11, a conversion chamber, and an outlet channel connected in sequence inside the housing 1, the outlet channel including a first outlet channel 131 and a second outlet channel 132, and a first outlet 14 and a second outlet 15 on the housing 1; the water distribution assembly 2 is disposed in the conversion chamber, and the water distribution assembly 2 has an inlet 21, a first water distribution port 22, and a second water distribution port 23 that are interconnected; the inlet 21 is connected to the inlet channel 11; the first water distribution port 22 is connected to the first outlet 14 through the first outlet channel 131; and the second water distribution port 23 is connected to the second outlet 15 through the second outlet channel 132.

[0032] The valve stem assembly 3 includes a valve stem 31 with a sealing part 32. The valve stem 31 is slidably inserted into the water distribution assembly 2 and can slide to the position where the sealing part 32 closes the first water distribution port 22 or the second water distribution port 23. In use, the user presses the valve stem 31 as needed to slide the sealing part 32 to the corresponding position, closing the unnecessary water distribution port, thereby achieving effective control and switching of water flow.

[0033] The faucet of this application, by setting a first water outlet 14 and a second water outlet 15, can meet different usage needs. The first water outlet 14 and the second water outlet 15 can be set with different functions or orientations according to the user's needs, making this faucet suitable for various usage scenarios such as oral cleaning and face washing. Users do not need to tilt or adjust the angle of the faucet when using it, making it more convenient to use.

[0034] The design of the water distribution component 2 makes the water flow switching more flexible. Users can easily select to close the first water outlet 22 or the second water outlet 23 by pressing the valve rod 31, thereby switching the water flow, simplifying the operation process, effectively avoiding water waste, and improving the efficiency of water resource utilization.

[0035] Reference Figure 4In some improvements of this application, the water distribution assembly 2 is provided with a water distribution channel 24 extending along a first direction x. The two ends of the water distribution channel 24 define the first water outlet 22 and the second water outlet 23. The water inlet 21 is opened on the peripheral wall of the water distribution channel 24. The valve stem 31 passes through the water distribution channel 24 along the first direction x, and the sealing part 32 slides between the two ends of the water distribution channel 24. By utilizing the space of the water distribution channel 24, the water inlet 21, the first water outlet 22, and the second water outlet 23 are integrated into one structure, greatly reducing the volume of the water distribution assembly 2. At the same time, the sliding cooperation with the valve stem 31 can realize the switching of water flow between the two water outlets, making the operation simple and convenient.

[0036] In some improvements of this application, the valve stem assembly 3 further includes an elastic element 33, which is disposed within the water distribution assembly 2 and abuts against the valve stem 31, and is capable of driving the valve stem 31 to move away from the water distribution assembly 2 along the first direction x. The elastic element 33 enables the sealing portion 32 of the valve stem 31 to remain in the position of sealing the first water distribution port 22 or the second water distribution port 23. In a specific embodiment of this application, the first water distribution port 22 is located above the second water distribution port 23, and the elastic element 33 drives the valve stem 31 to move toward the first water distribution port 22, so that the sealing portion 32 remains sealed to the first water distribution port 22. When the faucet is turned on, water flows from the water inlet channel 11 through the water inlet 21, the second water distribution port 23, and the second water outlet channel 132, and flows out from the second water outlet 15. When switching water outlets is required, the user presses the valve stem 31 to compress the spring, blocking the second branch outlet 23 with the sealing part 32. Water flows from the inlet channel 11 through the inlet 21, the first branch outlet 22, and the first outlet channel 131, exiting from the first outlet 14. Simultaneously, when the user stops pressing the valve stem 31, the water pressure causes the valve stem 31 to continuously press the elastic element 33, keeping the sealing part 32 in the sealed position for the second branch outlet 23. When the user closes the faucet, the water pressure disappears, and the valve stem 31 moves towards the first branch outlet 22 under the action of the elastic element 33, resetting to the position where the sealing part 32 blocks the first branch outlet 22. This eliminates the need for manual reset, greatly improving the convenience of using the second branch outlet 23 as a frequently used outlet and enhancing the user experience. Specifically, the elastic element 33 can be a spring.

[0037] In some improvements of this application, the water distribution assembly 2 is provided with an installation groove 25, which extends along the first direction x and communicates with the water distribution channel 24. The valve stem 31 is inserted into the installation groove 25 and connected to the installation groove 25 through the elastic member 33. This makes the installation and fixation of the valve stem 31 more stable and reliable, avoiding problems such as loosening or displacement. At the same time, the installation groove 25 can limit the movement trajectory of the valve stem 31, ensuring that it always slides along the first direction x, improving the performance and lifespan of the faucet.

[0038] In some improvements of this application, the valve stem assembly 3 further includes a sealing ring 34, which is sleeved on the valve stem 31 to define the sealing portion 32. In an embodiment of this application, two positioning portions are protruding from the peripheral wall of the valve stem 31 and spaced apart along a first direction x. The sealing ring 34 is located between the two positioning portions to fix the position of the sealing ring 34 on the valve stem 31. In other embodiments, the sealing ring 34 can also be fixed by forming an annular groove on the peripheral wall of the valve stem 31. Specifically, the cross-section of the outer peripheral wall of the sealing ring 34 can be V-shaped to further improve its sealing effect on the water outlet.

[0039] In some improvements of this application, the housing 1 includes a main body 17 and a water outlet 16. The first water outlet 14 and the second water outlet 15 are both located on the first end of the water outlet 16. The second end of the water outlet 16 is rotatably located on the top of the main body 17. The water inlet channel 11 and the conversion cavity are both located inside the main body 17. The water distribution assembly 2 is rotatably located inside the conversion cavity and is fixedly connected to the water outlet 16. An installation groove 161 is provided on the second end of the water outlet 16. The end of the valve stem 31 away from the water distribution assembly 2 slides through the installation groove 161.

[0040] By setting the first outlet 14 and the second outlet 15 at the first end of the water nozzle 16, and rotating the second end of the water nozzle 16 to the top of the main body 17, the water distribution assembly 2 can rotate within the conversion chamber 12 as the water nozzle 16 rotates. The water inlet 21 can communicate with the water inlet channel 11 through a port located on the rotation axis at the bottom of the water distribution assembly 2. The valve stem 31 is also located on the rotation axis of the water distribution assembly 2, ensuring the water outlet switching function of the water dispenser. This design retains the two-outlet switching function while realizing the rotatable function of the water nozzle 16. The water nozzle 16 can rotate 360° to the left and right, making it convenient for users to use water in different directions.

[0041] In a specific embodiment of this application, the valve stem 31 includes a rod body 311 and a button 312 connected sequentially along the first direction x. The sealing part 32 is located on the rod body 311. The button 312 is provided in the mounting groove by a spring and is flush with the upper surface of the spout 16. By pressing the button 312, the spring can be compressed to abut against the rod body 311, thereby moving the valve stem 311 downward to block the second water outlet 23. The rod body 311 maintains the position of blocking the second water outlet 23 under the action of water flow pressure. The button 312 is reset under the action of the spring to maintain the flatness and aesthetics of the entire faucet outer surface.

[0042] In some improvements of this application, the first water outlet 14 is located at the top of the water spout 16, and the second water outlet 15 is located at the bottom of the water spout 16. The second water outlet 15 faces downward and serves as a commonly used water outlet, configured for foaming water dispensing mode, suitable for routine use such as daily hand washing and cleaning; the first water outlet 14 faces upward and can be designed as a mouthwash water pattern, suitable for users to clean their mouths, improving portability and hygiene.

[0043] Reference Figure 5 In some improvements of this application, a switching valve core is also included. A third water outlet 18 is provided on the housing 1. The housing 1 also has a water supply channel 10 and a third water outlet channel 19 inside. The third water outlet channel 19 communicates with the third water outlet 18. The switching valve core is movably disposed within the housing 1. The switching valve core has an inlet end and an outlet end. The inlet end communicates with the water supply channel 10, and the outlet end can selectively communicate with either the inlet channel 11 or the third water outlet channel 19. The switching valve core can control the water flow to the third water outlet 18, or to the first water outlet 14 or the second water outlet 15 via the water distribution assembly 2, meeting different user water needs. In a specific embodiment of this application, a handle is also included. The handle is located outside the housing 1 and connected to the switching valve core. Controlling the handle allows control of the connection between the switching valve core and the internal channels of the housing 1. Specifically, opening the handle away from the housing 1 connects the outlet of the switching valve core to the third outlet channel 19. Water flows sequentially through the water supply channel 10, the inlet, the outlet, and the third outlet channel 19 before exiting from the third outlet 18. Pressing the handle closer to the housing 1 switches the outlet of the switching valve core to connect with the inlet channel 11. Water flows from the second outlet 15 when the valve stem 31 is not pressed, and from the first outlet 14 when the valve stem 31 is pressed. Rotating the handle rotates the switching valve core, thereby controlling the cross-section of the water flow between the inlet of the switching valve core and the water supply channel 10, thus controlling the water flow rate.

[0044] In some improvements of this application, the housing 1 includes a main body 17 and a water outlet 16. The first water outlet 14, the second water outlet 15, and the third water outlet 18 are all located on the first end of the water outlet 16, and the second end of the water outlet 16 is rotatably located on the top of the main body 17. The first water outlet 14 and the second water outlet 15 are both located on the top of the water outlet 16, and the third water outlet 18 is located at the bottom of the water outlet 16. The third water outlet 18, located at the bottom, can be used as a commonly used water outlet for hand washing, cleaning the sink, and collecting water, etc. The second water outlet 15 can be set to emit mouthwash-like water for daily oral cleaning. The first water outlet 14 can be set to emit a spray, further enriching the selection of water outlet modes.

[0045] Reference Figures 6-8 In some improvements of this application, a connecting component 4 is also included. The connecting component 4 is disposed inside the housing 1 and connected to the bottom of the water distribution component 2. The connecting component 4 has a first connecting channel 41 and a second connecting channel 42. The water outlet can selectively communicate with the water inlet channel 11 through the first connecting channel 41 or with the third water outlet channel 19 through the second connecting channel 42. The first connecting channel 41 has a first water inlet port 411 located at the bottom of the connecting component 4, and the second connecting channel 42 has a second water inlet port 421 located at the bottom of the connecting component 4. The first water inlet port 411 is located at the center of the connecting component 4, and the second water inlet port 421 is annular and surrounds the outer periphery of the first water inlet port 411. The connecting component 4 is connected to the water distribution component 2. When the water distribution component 2 rotates with the water outlet 16, the connecting component 4 rotates together. The first water inlet connection 411 is located at the center of the connecting component 4 and along the rotation axis. The second water inlet connection 421 is arranged in a ring shape to ensure that the rotation of the water outlet 16 remains unaffected even after adding multiple water outlets. (See the accompanying drawings for this application.) Figure 6 The arrow indicates the water flow path at the second outlet 15. Figure 7 The arrow indicates the water flow path at the third outlet 18. Figure 8 The arrow indicates the water flow path from the first outlet 14.

[0046] In some improvements of this application, the water supply channel 10 includes a hot water channel 101 and a cold water channel 102. The water inlet can be selectively connected to one or both of the hot water channel 101 and the cold water channel 102, realizing the function of mixing hot and cold water. Users can adjust the water temperature according to their own needs, improving the comfort and practicality of the faucet.

[0047] In summary, this utility model embodiment provides a faucet that controls the water distribution component 2 via the valve stem 31, enabling convenient switching and resetting between the first water outlet 14 and the second water outlet 15. Users can easily select different water flow modes and automatically reset without complex rotation or flicking operations, improving ease of use and comfort. Simultaneously, the spout 16 is a rotatable structure, allowing users to adjust the water flow direction according to actual needs, greatly expanding the faucet's applicability. Furthermore, this application also designs a third water outlet 18, expanding the water flow modes to include spray, rinsing, and bottom-aerated water, providing the faucet with more water flow options.
