After adopting the above solutions, the dual-outlet faucet of the present invention is provided with the first spout tube and the second spout tube, so that the dual-outlet faucet has two water channels. It is convenient for the user to use the normal water and the water processed by the water treatment apparatus. Specifically, when the dual-outlet faucet is in use, the cold water outlet of the valve seat is in communication with the inlet end of the second spout tube through the water treatment apparatus, so that the cold water output from the cold water outlet is processed by the water treatment apparatus to be output from the second spout tube and the second spray head. In this way, when the user controls the mixed water outlet to discharge water by operating the control valve core, the dual-outlet faucet outputs ordinary mixed water. When the user controls the cold water outlet to discharge water by operating the control valve core, the dual-outlet faucet outputs the water processed by the water treatment apparatus. In addition, the water output from the first spout tube and the second spout tube of the dual-outlet faucet can share the cold water input from the cold water inlet. This can reduce the pipeline of the external water source connected to the dual-outlet faucet and simplify the structure.
The dual-outlet faucet system of the present invention comprises the dual-outlet faucet and the water treatment apparatus. The inlet and the outlet of the water treatment apparatus are connected to the cold water outlet of the dual-outlet faucet and the inlet end of the second spout tube, respectively. When the user controls the mixed water outlet to discharge water by operating the control valve core, the dual-outlet faucet system outputs mixed water. When the user controls the cold water outlet to discharge water by operating the control valve core, the cold water output from the cold water outlet is processed by the water treatment apparatus and then output through the second spout tube and the second spray head. At this time, the dual-outlet faucet system outputs the water processed by the water treatment equipment.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

The dual-outlet faucet A of the present invention is provided with the first spout tube 31 and the second spout tube 32, so that the dual-outlet faucet A has two water channels. It is convenient for the user to use the normal water and the water processed by the water treatment apparatus B. Specifically, when the dual-outlet faucet A is in use, the cold water outlet 2121 of the valve seat 21 is in communication with the inlet end of the second spout tube 32 through the water treatment apparatus B, so that the cold water output from the cold water outlet 2121 is processed by the water treatment apparatus B to be output from the second spout tube 32 and the second spray head 34. In this way, when the user controls the mixed water outlet 2113 to discharge water by operating the control valve core 22, the dual-outlet faucet A outputs ordinary mixed water. When the user controls the cold water outlet 2121 to discharge water by operating the control valve core 22, the dual-outlet faucet A outputs the water processed by the water treatment apparatus B. In addition, the water output from the first spout tube 31 and the second spout tube 32 of the dual-outlet faucet A can share the cold water input from the cold water inlet 2111. This can reduce the pipeline of the external water source connected to the dual-outlet faucet A and simplify the structure.

The lower portion of the spout body 12 is rotatably connected to the mounting seat 111, so that the spout body 12 can be rotated to control the direction of the first spray head 33 and the second spray head 34. Specifically, the lower portion of the spout body 12 is provided with a connecting section 123. The side wall of the connecting section 123 is formed with a limiting hole 1231. The inner wall of the mounting seat 111 is formed with an annular groove 1111. The annular groove 1111 is fitted with a rotatable C-shaped ring 5. The annular groove 1111 is configured to restrict the up and down movement of the C-shaped ring 5. The connecting section 123 is inserted into the C-shaped ring 5. The C-shaped ring 5 is provided with a limiting elastic plate 51. The inner side of the limiting elastic plate 51 is provided with a limiting block 511 to be engaged with the limiting hole 1231. In the present invention, the C-shaped ring 5 and the connecting section 123 rotate together through the cooperation of the limiting block 511 and the limiting hole 1231, and the C-shaped ring 5 is rotatably fitted in the annular groove 1111 of the mounting seat 111, so that the spout body 12 can rotate relative to the mounting seat 111. When the spout body 12, the mounting seat 111 and the C-shaped ring 5 are assembled, the C-shaped ring 5 is first inserted into the mounting seat 111, so that the C-shaped ring 5 is placed into the annular groove 1111 of the mounting seat 111. Then, the connecting section 123 of the spout body 12 is inserted into the C-shaped ring 5, so that the limiting block 511 of the C-shaped ring 5 is engaged with the limiting hole 1231 of the connecting section 123. The limiting block 511 of the C-shaped ring 5 is provided with a guide slope 512 that is inclined in a top-down direction to the inner side of the limiting elastic plate 51. The limiting block 511 can be easily inserted into the limiting hole 1231 through the guide slope 512. The inner wall of the C-shaped ring 5 is formed with a positioning plane 52. The outer wall of the connecting section 123 of the spout body 12 is formed with a connecting plane 1232 to be pressed against the positioning plane 52. The cooperation of the connecting plane 1232 and the positioning plane 52 can achieve a positioning effect, so that the user can quickly align the limiting hole 1231 of the connecting section 123 with the limiting block 511 of the C-shaped ring 5. Moreover, the cooperation of the connecting plane 1232 and the positioning plane 52 enables the connecting section 123 and the C-shaped ring 5 to rotate together. The inner wall of the annular groove 1111 of the mounting seat 111 is formed with a recess 1112. The recess 1112 is configured to provide a space for the limiting elastic plate 51 to be deformed outwardly. In this way, when the spout body 12 is to be removed from the mounting seat 111, the spout body 12 is first rotated so that the connecting section 123 of the spout body 12 drives the C-shaped ring 5 to rotate to a position where the limiting elastic plate 51 of the C-shaped ring 5 faces the recess 1112. Then, an external tool is inserted into the mounting seat 111 to pass through the limiting hole 1231 and push the limiting block 511 to disengage from the limiting hole 1231. When the limiting block 511 is disengaged from the limiting hole 1231, the spout body 12 can be pulled out. When the limiting block 511 of the C-shaped ring 5 is engaged with the limiting hole 1231 of the connecting section 123 of the spout body 12, the connecting section 123 can be inserted into the C-shaped ring 5 first, so that the connecting plane 1232 of the connecting section 123 is against the positioning plane 52 of the C-shaped ring 5. Then, the connecting section 123 is rotated and pressed down. When the connecting section 123 drives the C-shaped ring 5 to rotate to the position where the limiting elastic plate 51 of the C-shaped ring 5 faces the recess 1112, the limiting elastic plate 51 is deformed so that the limiting block 511 of the C-shaped ring 5 is locked into the limiting hole 1231 of the connecting section 123. In order to quickly align the limiting elastic plate 51 the C-shaped ring 5 with the recess 1112, the connecting section 123 is provided with a positioning protrusion 1233 extending downwardly, and the inner wall of the mounting seat 111 is provided with a positioning portion 1113 that extends inwardly and is configured to lean against the side of the positioning protrusion 1233. When the connecting section 123 is rotated until the side of the positioning protrusion 1233 of the connecting section 123 leans against the positioning portion 1113 of the mounting seat 111, the connecting section 123 drives the C-shaped ring 5 to rotate until the limiting elastic plate 51 of the C-shaped ring 5 faces the recess 1112.
