The valve core 2 is arranged in the faucet body 1, and the valve seat 4 is arranged on the valve core 2. Specifically, the valve seat 4 has a mounting portion 16, and the valve seat 4 and the mounting portion 16 are integrally formed. A positioning hole 17 is opened on the mounting portion 16, and a positioning protrusion 18 is provided on the valve core 2. The positioning protrusion 18 passes through the positioning hole 17, and the positioning protrusion 18 is adapted to the positioning hole 17. In this embodiment, the number of the positioning protrusion 18 and the positioning hole 17 is two, and the positioning protrusion 18 corresponds to the positioning hole 17 one by one. The positioning protrusion 18 cooperates with the positioning hole 17 to ensure that the relative position of the valve core 2 and the valve seat 4 is stable, thereby improving the stability of the overall structure.

[0026] The faucet body 1 is internally threadedly connected to a limiting seat 20, the end face of the limiting seat 20 abuts against one end face of the valve core 2, and one end face of the mounting portion 16 abuts against the other end face of the valve core 2. A limiting convex ring 19 is arranged in the faucet body 1, and the end face of the limiting convex ring 19 abuts against the other end face of the mounting portion 16, thereby ensuring the relative stability of the valve core 2, the valve seat 4 and the faucet body 1.

[0027] A limiting protrusion 21 is provided on the inner side wall of the limiting protrusion ring 19, and a limiting groove 22 is provided on the side wall of the mounting portion 16. The limiting protrusion 21 is inserted into the limiting groove 22, and the limiting protrusion 21 is adapted to the limiting groove 22. The limiting protrusion 21 cooperates with the limiting groove 22 to limit the valve seat 4 circumferentially, thereby ensuring the stability of the valve seat 4. During installation, the installer can also determine the position of the valve seat 4 on the faucet body 1 by the relative position relationship between the limiting protrusion 21 and the limiting groove 22, thereby making the installation more convenient and quick.

[0028] It should be noted that during installation, first align the limiting groove 22 with the limiting protrusion 21, and then install the valve seat 4 into the faucet body 1, so that the limiting protrusion 21 is inserted into the limiting groove 22, until the end face of the limiting protrusion ring 19 abuts against the end face of the mounting portion 16, and then align the positioning protrusion 18 with the positioning hole 17, and then install the valve core 2 into the faucet body 1, so that the positioning protrusion 18 passes through the positioning hole 17, until the end face of the mounting portion 16 abuts against the end face of the valve core 2, and finally, the limiting seat 20 is threadedly connected to the faucet body 1 until the end face of the limiting seat 20 abuts against the end face of the valve core 2.

[0037] A guide strip 25 is provided on the inner side wall of the water outlet pipe 6. The guide strip 25 is provided along the axial direction of the water outlet pipe 6. The guide strip 25 is matched with the notch 26. The guide strip 25 and the notch 26 cooperate for guidance. The cooperation and guidance between the guide strip 25 and the notch 26 can further help the outer ring of the limiting ring 5 to be embedded in the annular groove 9, making the installation of the water outlet pipe 6 more convenient and quick. Moreover, the cooperation between the guide strip 25 and the notch 26 can further improve the relative stability of the water outlet pipe 6 and the buckle 8.

[0038] During installation, first sleeve the buckle ring 8 into the annular groove 7 of the joint 3, then embed the inner ring of the limiting ring 5 into the annular embedding groove 10, then align the guide strip 25 with the notch 26, and sleeve the water outlet pipe 6 onto the outside of the joint 3 by external force until the lower end face of the water outlet pipe 6 abuts against the upper end face of the annular flange 11, so that the outer ring of the limiting ring 5 is embedded in the annular embedding groove 9, and the installation is completed. During disassembly, it is only necessary to apply external force to the water outlet pipe 6 to remove it, so that the outer ring of the limiting ring 5 is separated from the annular embedding groove 9. The operation is simple, and no external tools are required, so it is convenient to disassemble and assemble.
