Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features.

[0025] It should be noted that the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0026] In the prior art, the gravity ball pull-out faucet needs to extend the water outlet pipe downward to connect the gravity ball and then extend upward out of the upper end of the housing, so two water inlet pipe connection ports and one water outlet pipe connection port need to be provided at the lower part of the valve seat. Figure 1 , three water pipe connection ports are opened on one surface, and a corresponding long water hole is set inside the valve seat, which will inevitably make the valve seat difficult to process and the cost high, and cause the valve seat and the shell to have a large size. In addition, the shell needs to accommodate two water inlet pipes, one water outlet pipe and a pull-out pipe (that is, the inner diameter of the shell needs to be able to accommodate at least four water pipes, and the pull-out pipe is connected to the water outlet pipe at the bottom). See Figure 2 , and the size of the shell is further increased. Therefore, the shell size of the prior art is large, not beautiful enough, and difficult to adapt to the installation requirements of various installation ports.

[0027] In view of this, see Figure 3-9 , an embodiment of the present application provides a pull-out faucet, comprising:

[0028] A shell 1, one side of which is provided with an interface; a valve seat 2 and a valve core 3, the valve seat 2 is arranged in the shell 1 and corresponds to the position of the interface 101, the lower part of the valve seat 2 is provided with two water inlet pipe connecting ports 202 for connecting two water inlet pipes 201 respectively, the upper part of the valve seat 2 is provided with a water outlet pipe connecting port 203, the side of the valve seat 2 is provided with a valve seat water outlet hole 205 connected with the water outlet pipe connecting port 203 and two valve seat water inlet holes 204 respectively connected with the two water inlet pipe connecting ports 202, the position of the valve seat water outlet hole 205 is located above the two water inlets of the valve seat 2, the valve core 3 is arranged at the interface 101, and assembled to the valve seat 2; an inner tube 4 and an outer tube 5, the inner tube 4 is connected with the water outlet pipe connecting port 203, the outer tube 5 is slidably sleeved outside the inner tube 4 and connected with the inner tube 4, and the outer part of the inner tube 4 is also sleeved with a spring 6 for providing a restoring force for resetting the outer tube 5;

[0029] Exemplarily, the housing 1 is a tubular structure, including a straight pipe or a curved pipe with various curvatures, and has a space inside to accommodate the water inlet pipe 201, the inner pipe 4, and the outer pipe 5;

[0030] Exemplarily, the interface extends outward to facilitate installation of the valve core 3, handles and other components, so as to operate the handle to adjust the temperature and water volume;

[0031] Exemplarily, the two water inlet pipes are a cold water inlet pipe and a hot water inlet pipe;

[0032] Regarding the defects of the prior art, see Figure 5-Figure 6 , the valve seat 2 of this embodiment is only provided with two water inlet pipe connection ports 202 at the lower part, and the water outlet pipe connection port 203 is provided at the upper part of the valve seat 2. Correspondingly, the side of the valve seat 2 is provided with a valve seat water outlet hole 205 connected with the water outlet pipe connection port 203 and two valve seat water inlet holes 204 respectively connected with the two water inlet pipe connection ports 202. The position of the valve seat water outlet hole 205 is located above the water inlets of the two valve seats 2. Obviously, since only two water pipe connection ports are provided at the lower part of the valve seat 2, the corresponding valve seat water outlet hole 205 and valve seat water inlet hole 204 are also respectively located above and below the side of the valve seat 2, which reduces the length of the water hole, thereby reducing the processing difficulty and cost, and the structure is simpler. Moreover, since the lower part only needs to connect and accommodate two water inlet pipes 201, see Figure 2 , thus greatly reducing the size of the housing 1 and improving the overall aesthetics and ease of installation of the pull-out faucet;

[0033] Exemplarily, a connection structure is provided at a position corresponding to the interface inside the housing 1 for realizing the installation of the valve seat 2;

[0034] The valve seat 2 designed in this embodiment is realized by using the inner tube 4, the outer tube 5 and the spring 6 to realize the pulling and drawing.
