[0032] Reference Figures 1 to 5As shown, a faucet inner core includes an inner core body 1, a sealing ring 2, and a water outlet connector 3. The inner core body 1 forms a valve core mounting seat 4, and the lower end of the valve core mounting seat 4 is connected to a water outlet channel 40. An elongated water passage groove 41 is recessed into the side wall of the valve core mounting seat 4, and guide grooves 42 are provided on both sides of the elongated water passage groove 41. The water outlet channel 40 is connected to the lower end of the elongated water passage groove 41. A water outlet connector 5 is formed on the water outlet connector 3, communicating with the water outlet channel 40. An annular groove 6 for fixing the sealing ring 2 is provided on the side of the water outlet connector 3 near the elongated water passage groove 41. Guide blocks 30 adapted to the guide grooves 42 are provided on both sides of the water outlet connector 3. During assembly, the sealing ring 2 is first embedded in the annular groove 6 of the water outlet connector 3, and then the water outlet connector 3 is embedded in the guide groove 42 through the guide blocks 30, so that the water outlet connector 3 and the valve core mounting seat 4 are fixedly assembled.

[0033] Specifically, the sealing ring 2 is annular, and the outer ring surface of the sealing ring 2 is fitted and sealed to the inner ring surface of the elongated water passage 41; the bottom surface of the elongated water passage 41 and the inner ring surface of the sealing ring 2 form a water flow lifting channel 7, which can lift the water flow height in the water outlet channel 40, and can meet the structural design requirements of the faucet spout within a certain height range.

[0034] To further secure the valve core, a valve core mounting groove 9 is provided in the valve core mounting seat 4. During assembly, the valve core is installed in the valve core mounting groove 9, and the valve core can be used to control the opening and closing of the water outlet and the flow rate.

[0035] In this embodiment, the lower end of the valve core mounting base 4 is provided with an inlet pipe 8 along the axial direction, and the lower end of the inlet pipe 8 is provided with a water pipe connector 80 for connecting to an external water pipe, so that the inlet pipe can be firmly installed.

[0036] In order to enable the entry of cold and hot water when the water inlet pipe is in use, the water inlet pipe 8 includes a cold water inlet pipe 81 and a hot water inlet pipe 82 arranged side by side. The water pipe connector 80 is sleeved on the bottom of the cold water inlet pipe 81 and the hot water inlet pipe 82 to position the bottom of the cold water inlet pipe 81 and the hot water inlet pipe 82. The upper ends of the cold water inlet pipe 81 and the hot water inlet pipe 82 are integrally formed with the valve core mounting seat 4.

[0037] It should be noted that the bottom of the valve core mounting groove 9 is provided with an inlet hole 90 that communicates with the inlet pipe 8 and an outlet hole 91 that communicates with the outlet channel 40. When water flows in from the inlet pipe, it is controlled by the valve core to enter the outlet channel through the outlet hole 91 and finally flows out from the outlet connector 5 to the outlet pipe.
