[0053] A preferred embodiment is described below in conjunction with the accompanying drawings so as to more completely and fully convey the present application.

[0054] As Figures 1-7 shown, the present embodiment discloses a waterway board, which comprises a waterway board body 1 and a waste water ratio adjustable valve 2, the inside of the waterway board body 1 has a waste water passage, the waste water passage is communicated through the inside passage of the waste water ratio adjustable valve 2, the waterway board body 1 has a valve seat 11 thereon, the valve seat 11 is provided with a first flow hole 111 and a second flow hole 112, the first flow hole 111 and the second flow hole 112 are both located on the waste water passage, the first flow hole 111 is arranged in extension along a direction perpendicular to the valve seat 11, the inner diameter of the first flow hole 111 is gradually reduced in a conical structure from outside to inside, the waste water ratio adjustable valve 2 comprises a valve core 21, a sealing cover 22 and a drive mechanism 23, the valve core 21 has an abutment portion 211, the abutment portion 211 is arranged in correspondence with the first flow hole 111, the valve core 21 can be moved in a direction approaching or away from the valve seat 11 to change the flux of the first flow hole 111, the sealing cover 22 is installed on the valve seat 11, the valve core 21 passes through and is slidably arranged in the sealing cover 22, a passage 221 is formed between the sealing cover 22 and the valve seat 11, the passage 221 communicates the first flow hole 111 and the second flow hole 112, and the drive mechanism 23 is used to drive the valve core 21 to move in the direction approaching or away from the valve seat 11.

[0055] As Figures 1-7As shown, in the present embodiment, the waterway plate is provided with a wastewater ratio adjustable valve 2 on the internal wastewater passage. Since the first flow-through hole 111 and the second flow-through hole 112 are both located on the wastewater passage, the first flow-through hole 111 on the valve seat 11 is in communication with one end of the wastewater passage, and the second flow-through hole 112 on the valve seat 11 is in communication with the other end of the wastewater passage. The wastewater passage is in communication through the internal passage of the wastewater ratio adjustable valve 2. At the same time, since the inner diameter of the first flow-through hole 111 is gradually reduced from the outside to the inside in a tapered structure, when the abutting portion 211 of the valve core 21 moves in the direction close to the first flow-through hole 111, the flow rate of the first flow-through hole 111 will decrease, and when the abutting portion 211 of the valve core 21 moves in the direction away from the first flow-through hole 111, the flow rate of the first flow-through hole 111 will increase, thereby realizing the flow rate adjustment of the first flow-through hole 111, changing the flow rate of the wastewater passage, and realizing the adjustment of the wastewater flow rate, so as to facilitate the user to adjust the wastewater size according to the needs, and further obtain purified water with different mineral content.

[0056] For example, in an area with good water quality, the wastewater ratio adjustable valve 2 can be adjusted to reduce the flow rate of the wastewater passage and reduce the wastewater. For another example, in an area with relatively high ion content in water, the wastewater ratio adjustable valve 2 can be adjusted to increase the flow rate of the wastewater passage, improve the retention rate of the membrane, and reduce the ion content in the purified water.

[0057] As shown in Figures 2-4 , the waterway plate body 1 has a recessed portion 12, and the valve seat 11 is arranged at the bottom of the recessed portion 12. Arranging the valve seat 11 at the bottom of the recessed portion 12 facilitates the installation and fixation of the valve core 21, and facilitates the sealed connection between the valve core 21 and the valve seat 11.

[0058] As shown in Figure 3 and Figure 7 , the wastewater ratio adjustable valve 2 further comprises a sealing member 24, and the sealing member 24 is arranged on the outside of the abutting portion 211. The sealing member 24 is arranged on the abutting portion 211 of the valve core 21, which improves the sealing effect of the valve core 21 sealing the first flow-through hole 111. Preferably, the sealing member 24 is made of rubber material, which can reduce the friction between the abutting portion and the valve seat and protect the abutting portion of the valve core.

[0059] As shown in Figure 3 and Figure 7 , the wastewater ratio adjustable valve 2 further comprises a first sealing ring 25, and the first sealing ring 25 is arranged on the outer circumferential side of the valve core 21 and abuts against the sealing cover 22. By arranging the first sealing ring 25 between the valve core 21 and the sealing cover 22, the sealing effect between the valve core 21 and the sealing cover 22 is improved, and water leakage from the gap between the valve core 21 and the sealing cover 22 is prevented.

[0060] As shown in Figure 3 and Figure 7As shown, the wastewater ratio adjustable valve 2 also includes a second sealing ring 26. The second sealing ring 26 is sleeved on the outer periphery of the sealing cover 22, and the outer periphery of the second sealing ring 26 abuts against the inner wall of the recess 12. The second sealing ring 26 is used to seal the gap between the inner wall of the recess 12 and the sealing cover 22, preventing water leakage from the gap between the outer periphery of the sealing cover 22 and the inner wall of the recess 12, and improving the sealing effect.

[0061] like Figure 3 and Figure 7 As shown, the wastewater ratio adjustable valve 2 also includes a third sealing ring 27, which is disposed between the sealing cover 22 and the valve seat 11. The third sealing ring 27 is embedded in the valve seat 11 or the sealing cover 22. The third sealing ring 27 is positioned between the sealing cover 22 and the valve seat 11, and is pressed against the valve seat 11 by the sealing cover 22. The third sealing ring 27 seals the gap between the valve seat 11 and the sealing cover 22, preventing water from leaking out from the gap and improving the sealing effect.

[0062] like Figures 1-7 As shown, the wastewater ratio adjustable valve 2 also includes a pressure cap 28. The pressure cap 28 is installed on the water circuit board body 1 by fasteners. The pressure cap 28 is sleeved on the valve core 21 and embedded in the recess 12. The lower edge of the pressure cap 28 abuts against the upper edge of the sealing cover 22. The pressure cap 28 is installed on the water circuit board body 1 by fasteners. The pressure cap 28 limits and fixes the sealing cover 22 to the valve seat 11, which facilitates the installation and removal of the sealing cover 22 and also improves the fixing effect of the sealing cover 22.

[0063] like Figure 3 and Figure 7 As shown, the wastewater ratio adjustable valve 2 also includes a threaded component 29, which is installed on the outside of the sealing cover 22. The valve core 21 passes through and is threadedly connected to the threaded component 29. The threaded component 29 fixes the valve core 21, and can also be rotated to move the valve core 21 towards or away from the valve seat 11, thereby adjusting the flow rate of the first flow hole 111. The threaded component 29 is a nut.

[0064] In this embodiment, the drive mechanism 23 includes a motor, the output shaft of which is connected to the valve core 21. The motor drives the valve core 21 to rotate. The motor can be electrically connected to a controller, which controls the rotation of the motor, facilitating automatic control and adjusting the size of the wastewater passage.

[0065] In another embodiment, the drive mechanism 23 includes a knob mounted on the end of the valve core 21. The size of the wastewater passage can be adjusted by manually rotating the knob, making the operation simple and convenient.

[0066] The embodiment also discloses a water dispenser comprising the waterway plate.
