[0033] The present invention will be further described below through specific embodiments.

[0034] See Figures 1 to 7 An integrated water tank includes a water tank 10, a valve body assembly 20, and a first water outlet module 30. The valve body assembly 20 includes a main body 21 and at least one switch valve core 22. The main body 21 is provided with at least one inlet channel 24 and at least one outlet channel 26. The inlet channel 24 is used for water intake and may include one or both of cold and hot water inlet channels 24. The number of outlet channels 26 can be one, two, or even more. The switch valve core 22 is mounted on the main body 21 and is provided with a button 22a, which controls the opening or closing of the corresponding outlet channel 26. The first water outlet module 30 is connected to one of the outlet channels 26, representing a single water outlet mode.

[0035] The water tank 10 is a one-piece molded structure, comprising several side walls 11, a bottom wall 12, and a platform 13. The side walls 11 are sequentially connected and together with the bottom wall 12 form a cavity with an open top. The platform 13 is located on the top surface of the side walls 11 and surrounds the top surface of the cavity. A mounting groove 14 is provided below the platform 13 in the water tank 10. The mounting groove 14 is located on the top outer periphery of the side walls 11 of the water tank 10 and has an opening 14a on the side wall 11. The main body 21 can be inserted into the mounting groove 14 through the opening 14a. Specifically, the water tank 10 has a shell 15 with a notch. The notch of the shell 15 is opposite to and connected to the side wall 11 of the water tank 10 with the opening 14a to form the mounting groove 14. The shell 15 and the water tank 10 can be integrally molded or welded separately.

[0036] The main body 21 has an inlet 24a at the inlet end of the water inlet channel 24 and an outlet 26a at the outlet end of the other water outlet channel 26. The bottom surface of the housing 15, which is also the bottom surface of the mounting groove 14, has through holes 14b at both the inlet 24a and the outlet 26a. A water inlet hose can pass through the through hole 14b opposite to the inlet 24a to connect to it, and a water outlet hose can also pass through the through hole 14b opposite to the outlet 26a to connect to it. This water outlet hose can be used to connect to other water outlet modules. Sealing rings 27 are installed between the outer periphery of the connection between the inlet 24a and the through hole 14b, and between the outer periphery of the connection between the outlet 26a and the through hole 14b, to prevent leakage at the connection point. A check valve 25 is also installed on the water inlet channel 24 to prevent hot and cold water from mixing.

[0037] The main body 21 of the valve body assembly 20 is fixed in the mounting groove 14. The size of the mounting groove 14 can be larger than the size of the valve body assembly 20 to facilitate the accommodation of the valve body assembly 20. At least one fixing block 16 is provided on the side wall 11 of the mounting groove 14 opposite to the opening 14a. The main body 21 is fixed by at least one fastener 17 passing through the valve body and fixing it to the corresponding fixing block 16. The number of fixing blocks 16 can be one, two or more, and the multiple fixing blocks 16 can be distributed at intervals along the axial direction of the main body 21. Figure 2 In the example, three fixed blocks 16 are used.

[0038] Furthermore, the fixing block 16 is located near the top of the mounting groove 14. The side of the fixing block 16 opposite to the main body 21 is also provided with an inclined surface 16a that extends from top to bottom away from the opening 14a. When the main body 21 is locked in the mounting groove 14, the inclined surface 16a is in close contact with the main body 21 and exerts downward pressure on the main body 21, thereby pressing the sealing ring 27 to ensure the sealing effect and prevent residual water droplets in the mounting groove 14 from leaking out.

[0039] To facilitate the drainage of residual water in the mounting groove 14, the bottom surface of the mounting groove 14 is set to be inclined, with the bottom surface sloping downward from the side away from the opening 14a towards the side where the opening 14a is located, so that the residual water can be drained from the opening 14a side.

[0040] This invention mounts the first water outlet module 30 and the button 22a side-by-side at the opening 14a, thereby sealing the opening 14a. The first water outlet module 30 is fixed to the valve body assembly 20, for example, by screws. The first water outlet module 30 and the button 22a of the switch valve core 22 are arranged along the axial direction of the main body 21. There may be gaps between the first water outlet module 30, the button 22a, and the opening 14a to facilitate the drainage of residual water in the mounting groove 14.

[0041] The first water outlet module 30 includes a water outlet body 31 and a water inlet interface 32. The water outlet body 31 is installed at the opening 14a and its length direction is parallel to the axial direction of the main body 21. Several water outlet holes 33 are provided on the side of the water outlet body 31 facing away from the main body 21, and the water outlet body 31 has a water cavity inside. The water inlet interface 32 is connected to the side of the water outlet body 31 facing away from the water outlet holes 33, and the water inlet connects the water cavity of the water outlet body 31 and one of the water outlet channels 26 of the main body 21. The shape of the first water outlet module 30 is adapted to the shape of the opening 14a of the mounting groove 14, for example, it is rectangular. Several water outlet holes 33 are distributed on the water outlet side of the water outlet body 31, forming a waterfall-like water spray module.

[0042] In this invention, the valve body assembly 20 is further provided with a temperature regulating valve core 28. One end of the temperature regulating valve core 28 passes through the platform 13 and is inserted into the main body 21, and it is provided with a knob 29 to adjust the water temperature of the outlet channel 26. The knob 29 is located above the platform 13. Specifically, the platform 13 is provided with an installation port 18 for the temperature regulating valve core 28 to pass through. The main body 21 is provided with a mixing chamber 21a for the temperature regulating valve core 28 to be installed. The inlet channel 24, the mixing chamber 21a, and the outlet channel 26 are connected along the axial direction of the main body 21. The main body 21 can be a one-piece molded structure or a modular assembly. Figure 3 In the main body 21, the structure is divided into three parts: water inlet channel 24, water mixing chamber 21a and water outlet channel 26. The adjacent two parts are connected by threaded joints to achieve detachable fixed connection. The connection is sealed by sealing ring 27. The three-part structure is locked after docking, which reduces the assembly difficulty. The specific structure and connection relationship of the main body 21 are not limited to this.

[0043] Specifically, the temperature control valve core 28 can be implemented using a commonly available temperature control valve core 28. For example, the temperature control valve core 28 also includes an adjusting component 28a, a pressure cap 28b, an anti-rotation plate 28c, and a sleeve 28d. The adjusting component 28a includes a rotating component and a rod, which are fixedly connected by screws. During assembly, the adjusting component 28a can be pre-installed in the mixing chamber of the valve body. A cover 28g is also fitted around the rotating component for limiting its position. The height of the rotating component is set so as not to affect the main body from being inserted into the mounting slot through the opening. One end of the rod passes through the platform 13 and is inserted into the mixing chamber 21a of the main body 21, and is fixed to the rotating component by screws. The rotating component is provided with a cold water passage hole 28e and a hot water passage hole 28f. By driving the rotating component to rotate, the cold and hot water passage areas are changed, thereby achieving temperature control. The sleeve 28d is fitted around the adjusting component 28a, and the height of the area of ​​the sleeve 28d on the platform 13 can be adjusted as needed. After adjusting the height of the sleeve 28d, the anti-rotation plate 28c is inserted into the mounting groove 14 through the opening 14a and fitted over the sleeve 28d, thereby restricting the circumferential rotation of the sleeve 28d, ensuring it is at the current height, and not affecting the installation of other components. The pressure cap 28b is fitted over the sleeve 28d and threaded to it, with its bottom surface abutting against the platform 13. The knob 29 is fixed to the other end of the adjusting member 28a and covers the outer periphery of the sleeve 28d. By rotating the knob 29, the end of the adjusting member 28a rotates within the mixing chamber 21a, thereby adjusting the amount of cold and hot water entering the mixing chamber 21a, and thus adjusting the temperature of the mixed water entering the outlet channel 26.

[0044] Furthermore, it also includes a second water outlet module 40 and a connecting pipe 41. The inlet end of the second water outlet module 40 passes through the countertop 13 and is located below the countertop 13, while the other end serves as the outlet end located above the countertop 13. One end of the connecting pipe 41 is connected to the inlet end of the second water outlet module 40, and the other end passes through the corresponding through hole 14b of the mounting groove 14 and connects to another water outlet channel 26 of the main body 21. The connecting pipe 41 can be a flexible water outlet hose. The countertop 13 can be provided with a corresponding mounting port 18 near the mounting groove 14 for the second water outlet module 40 to pass through. The second water outlet module 40 is a faucet, such as a pull-out faucet.

[0045] During installation, the switch valve core 22 and the rotating component are pre-installed into the main body 21. Then, the main body 21 is installed into the mounting groove 14 through the opening 14a of the mounting groove 14. The end of the sleeve 28d is passed from top to bottom through the mounting port 18 of the table 13 and screwed into the mixing chamber 21a of the main body 21. An anti-rotation piece 28c is inserted from the opening 14a to restrict the rotation of the sleeve 28d. The rotating fastener 17 is used to fix the valve body to the fixing block 16. After that, the first water outlet module 30 and the button 22a of the switch valve core 22 are installed and locked at the opening 14a. The bottom end of the rod of the adjusting component 28a is passed from top to bottom through the sleeve 28d and installed into the mixing chamber 21a of the valve body. It is connected to the rotating component by screws. The pressure cap 28b is fitted onto the outer periphery of the sleeve 28d located on the table 13. The knob 29 is installed on the top of the adjusting component 28a. Connect the inlet 24a of the inlet channel 24 and the outlet 26a of the outlet channel 26 to the corresponding hoses respectively; install the second outlet module 40 and its connecting pipe 41.

[0046] The installation and maintenance of the valve body assembly 20 mentioned above are all carried out on the countertop 13, which can be adapted to the three installation methods of countertop basin, mid-mount basin and undermount basin, reducing maintenance costs and risks.
