[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0022] like Figures 1-10 As shown, this embodiment discloses a valve core for a shower, including a housing 1. The bottom of the housing 1 is provided with a cold water inlet 2, a hot water inlet 3, and at least two water outlets 19. Specifically, this embodiment provides two water outlets 19, which can be connected to the overhead shower and the shower head respectively. A water temperature regulating device is provided inside the housing 1. The water temperature regulating device includes a first static valve plate 4, a first dynamic valve plate 5 disposed on the first static valve plate 4, and a first control component disposed on the first dynamic valve plate 5, such as... Figure 4As shown, the first stationary valve plate 4 is provided with a cold water channel 42 connected to the cold water inlet 2 and a hot water channel 41 connected to the hot water inlet 3. A mixing chamber 43 is provided between the first stationary valve plate 4 and the first moving valve plate 5, which is connected to both the cold water channel 42 and the hot water channel 41. The mixing chamber 43 can be connected to any outlet 19. The cold water from the cold water inlet 2 and the hot water from the hot water inlet 3 can be discharged from the cold water channel 42 and the hot water channel 41, and then mixed through the mixing chamber 43. In this embodiment, the first control component can drive the first moving valve plate 5 to slide and rotate. The sliding of the first moving valve plate 5 can control the opening and closing of the cold water channel 42, the hot water channel 41 and the mixing chamber 43. When the first moving valve plate 5 closes the cold water channel 42 and the hot water channel 41, the water cutting-off function is realized; and when the cold water channel 42 and the hot water channel 41 are connected to the mixing chamber 43, the water supply function is realized. In addition, the rotation of the first moving valve plate 5 can control the drainage ratio of the cold water channel 42 and the hot water channel 41, thereby effectively regulating the outlet water temperature.

[0023] like Figure 5 As shown, a water distribution device is also provided inside the housing 1. The water distribution device is located between the mixing chamber 43 and the outlet 19. The water distribution device includes a second static valve plate 6, a second dynamic valve plate 7 rotatably mounted on the second static valve plate 6, and a second control component disposed inside the housing 1. The second dynamic valve plate 7 is provided with a communication port 71, and the second static valve plate 6 is provided with a control port 61 corresponding to the outlet 19. The number and position of the control ports 61 match the outlet 19. The communication port 71 is used to connect the mixing chamber 43 with the control port 61. The second control component is used to control the communication port 71 to connect with different control ports 61, thereby controlling the water output of different outlets 19.

[0024] like Figure 6 As shown, in this specific embodiment, the first control component includes a valve seat 8 rotatably mounted on the top of the housing 1, a lever 9 rotatably mounted on the valve seat 8, and a connecting seat 10 mounted at the bottom of the valve seat 8. The top of the connecting seat 10 is slidably connected to the valve seat 8, and the bottom is engaged with the first movable valve piece 5. The bottom of the lever 9 extends into the connecting seat 10, and rotation of the lever 9 can drive the connecting seat 10 to slide. Specifically, a rotating shaft 11 is provided inside the valve seat 8, and the lever 9 is rotatably connected to the valve seat 8 through the rotating shaft 11. A connecting groove 101 is provided at the bottom of the connecting seat 10, and the bottom of the lever 9 extends into the connecting groove 101. The lever 9 can drive the valve seat 8 and the first movable valve piece 5 to rotate. When the lever 9 is moved, the bottom of the lever 9 will drive the connecting seat 10 to move. Since the connecting seat 10 is engaged with the first movable valve piece 5, ... Figure 8 As shown, this will synchronously drive the first moving valve plate 5 to move, thereby controlling the opening and closing of the cold water channel 42, the hot water channel 41, and the mixing chamber 43. At the same time, the lever 9 can be rotated, which will drive the connecting seat 10 and the first moving valve plate 5 to rotate through the valve seat 8 to adjust the water temperature.

[0025] To ensure that the water in the mixing chamber 43 can be smoothly discharged through the outlet 19, a connecting seat 12 is provided at the bottom of the first static valve plate 4. This connecting seat 12 connects the cold water inlet 2 to the cold water channel 42, the hot water inlet 3 to the hot water channel 41, and the mixing chamber 43 to the connecting port 71. The connecting seat 12 has a corresponding number of through holes, allowing the water in the mixing chamber 43 to flow out through these holes. A transition static valve plate 13 is provided between the connecting seat 12 and the second dynamic valve plate 7 to achieve communication between the two, facilitating water discharge through the drain port.

[0026] like Figure 7 As shown, in this embodiment, a sealing sleeve 14 is also provided on the connecting seat 12. The sealing sleeve 14 is located inside the through hole and is used to ensure the seal between the connecting seat 12 and the first stationary valve plate 4, and between the connecting seat 12 and the transition stationary valve plate 13. The top and bottom of the sealing sleeve 14 are both higher than the surface of the connecting seat 12 and are made of rubber. Because the height of the sealing sleeve 14 exceeds the surface of the connecting seat 12, the sealing sleeve 14 can effectively achieve a seal between the first stationary valve plate 4 and the transition stationary valve plate 13 under the squeezing action. Compared with adding a sealing ring, the cost is lower and the processing is more convenient.

[0027] In this embodiment, the second control component includes a rotating sleeve 15 rotatably connected to the housing 1, the bottom of which is engaged with the second movable valve plate 7. Rotating the rotating sleeve 15 via the operating handle 17 rotates the second movable valve plate 7. Specifically, the housing 1 has a groove 16, and the top of the rotating sleeve 15 is equipped with a handle 17 that can rotate within the groove 16. Figure 9 As shown, by actuating the handle 17, the rotating sleeve 15 rotates within the housing 1, thereby driving the first moving valve plate 5 to rotate, thus achieving the switching of different water outlets 19. In addition, a sealing ring 18 is provided at the bottom of the housing 1 to enhance the sealing performance of the cold water inlet 2, the hot water inlet 3, and the drain outlet.

[0028] In summary, the valve core disclosed in this utility model has a cold water inlet 2, a hot water inlet 3, and at least two water outlets 19 at its bottom. Cold water and hot water enter the mixing chamber 43 through the cold water channel 42 and the hot water channel 41, respectively, and are moved and rotated by the first control component. The rotation of the first moving valve 5 can adjust the ratio of cold water to hot water inlet, thereby controlling the water temperature; at the same time, its movement can control the opening and closing of the cold water channel 42, the hot water channel 41, and the mixing chamber 43, thereby controlling the opening and closing of the water outlet. When the mixed water enters the mixing chamber 43, the second control component can control the connection state between the connecting port 71 and each water outlet 19, realizing the switching of different water outlets 19. This valve core integrates water outlet on / off control, water temperature adjustment, and water distribution functions, with a high degree of integration, effectively reducing the space occupied by the shower.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
