[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0031] A faucet valve seat structure, combined with Figure 1-10 As shown, the device includes a valve seat body 1, on which are provided a cold water channel 2, a hot water channel 3, a first water outlet 4, and a second water outlet 5. One end of the cold water channel 2 is a cold water inlet 6, and the other end is a cold water outlet 12, connecting the cold water inlet 6 and the cold water outlet 12. One end of the hot water channel 3 is a hot water inlet 7, and the other end is a hot water outlet 13, connecting the hot water inlet 7 and the hot water outlet 13. The cold water inlet 6 is used to connect to a first water source, which is a cold water source, such as directly connected to the cold water pipe in a household water supply network. The hot water inlet 7 is used to connect to a second water source. The first water source is a hot water source, such as a hot water pipe connected to a household water heater or a household water network. The valve seat body 1 is used to cooperate with a hot and cold water mixing valve 8. The hot and cold water mixing valve 8 has a cold water inlet 9, a hot water inlet 10, and a mixing outlet 11. The cold water inlet 9 is connected to the cold water outlet 12, and the hot water inlet 10 is connected to the hot water outlet 13. The hot and cold water mixing valve 8 is used to adjust the ratio of water supplied from the cold water inlet 9 and the hot water inlet 10 to the mixing outlet 11 and the water flow rate of the mixing outlet 11. Specifically, the hot and cold water mixing valve 8 is equipped with a mixing valve handle 27, which is operated by moving along the first direction ( Figure 7 The hot and cold water ratio is adjusted by rotating the mixing valve handle 27 in the direction of the arrow (as indicated by the arrow on the handle). Figure 6The mixing valve handle 27 (arrow direction) is rotated to adjust the flow rate of hot and cold water (including shutting off the water flow when the flow rate is zero). Since the internal structure of the hot and cold mixing valve 8 that achieves the above function is a conventional technical means in this field, it will not be described in detail in this embodiment. The mixing outlet 11 of the hot and cold mixing valve 8 is connected to the inlet 14 of the first outlet channel. When the valve seat structure is installed on the faucet 28, the outlet 16 of the first outlet channel is used to connect to the first faucet outlet 17 of the faucet 28 to supply water to the first faucet outlet 17. The inlet 15 of the second outlet channel is connected to the cold water channel 2 in the valve seat body 1 so that the water in the cold water channel 2 can flow to the second outlet channel 5. When the valve seat structure is installed on the faucet 28, the outlet 18 of the second outlet channel is used to connect to the second faucet outlet 19 of the faucet 28 to supply water to the second faucet outlet 19.

[0032] In the application scenario of this embodiment, the second faucet outlet 19 is used to flow out purified water. Therefore, a filter structure 22 should also be provided between the second water outlet 18 and the second faucet outlet 19. The filter structure 22 is used to filter the water flow from the second water outlet 18 and supply it to the second faucet outlet 19. The specific construction of the filter structure 22 is not limited. It can be any existing structure and material that can be used to filter water flow.

[0033] To facilitate the switching of water flow from the second faucet outlet 19, a single-cooling switch valve 20 is preferably installed between the second water outlet inlet 15 and the second faucet outlet 19. The single-cooling switch valve 20 is used to open and close the connection between the second water outlet inlet 15 and the second faucet outlet 19. The single-cooling switch valve 20 can be any existing water flow switch valve, and can be electrically controlled or manually controlled. Specifically, in this embodiment, a manual switch valve is selected, which is equipped with a water purification switch handle 29. The water purification switch handle 29 is turned... Figure 6 The flow rate of the second faucet outlet 19 is adjusted by the arrow direction of the water purification switch handle 29 (including shutting off the water flow when the flow rate is zero). The specific structure of the single-cooling switch valve 20 that achieves this function is also a conventional technical means in this field, and therefore will not be described in detail. In order to facilitate the installation of the single-cooling switch valve 20 onto the valve seat body 1, in a preferred embodiment, the valve seat body 1 is provided with an installation port 21. The installation port 21 connects the second water outlet 5 between the second water outlet inlet 15 and the second water outlet 18. The installation port 21 is used for the insertion and installation of the single-cooling switch valve 20, so as to open and close the conduction between the second water outlet inlet 15 and the second water outlet 18 through the single-cooling switch valve 20, thereby controlling the opening and closing of the water flow of the second faucet outlet 19.

[0034] To facilitate the installation of the hot and cold water mixing valve 8, the valve seat body 1 is provided with an assembly surface 24. The cold water outlet 12, the hot water outlet 13, and the first outlet inlet 14 are all located on the assembly surface 24. The hot and cold water mixing valve 8 has an installation surface 30. The cold water inlet 9, the hot water inlet 10, and the mixing water outlet 11 of the hot and cold water mixing valve 8 are all located on the installation surface 30 (this is the conventional structure on the hot and cold water mixing valve 8). The positions of each outlet are matched and correspond. The installation surface 30 is then sealed and fitted onto the assembly surface 24 and then fixed (by screws, etc.). This completes the installation of the hot and cold water mixing valve 8 on the valve seat body 1, realizing the assembly surface 24 for the hot and cold water mixing valve 8 to be connected and assembled.

[0035] To facilitate water connection, in a preferred embodiment, the cold water inlet 6 is used for the installation of one end of a cold water pipe 25, and the other end of the cold water pipe 25 is connected to a first water source; the hot water inlet 7 is used for the installation of one end of a hot water pipe 26, and the other end of the hot water pipe 26 is connected to a second water source; and the first water outlet 16 is used for the installation of one end of a water outlet pipe 23, and the other end of the water outlet pipe 23 is connected to the first faucet outlet 17.

[0036] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
