The upper water flow channel 202 and the lower water flow channel 203 are communicated with a water passing groove 301 inside the valve core 3 through a water outlet hole 207 and a water inlet hole 208 on a valve core installation position 206, and the on-off of the water flow channel is controlled by the valve core 3. Water outlet ends 204 and water inlet ends 205 that communicate the upper water flow channel 202 and the lower water flow channel 203 are respectively arranged at the upper and lower ends of the water-passing inner core 2. When the water outlet pipe 5, the water inlet pipe 6 and the valve core 3 need to be installed, only the water outlet pipe 5 and the water inlet pipe 6 need to be respectively extended into the water outlet end 204 and the water inlet end 205, and the water outlet pipe 5 and the water inlet pipe 6 are fixed through an external locking part and the outer shell 1, thereby realizing the installation of the water outlet pipe 5 and the water inlet pipe 6.

[0039] As Figure 12 shown: A clamping part 213 is further arranged on the valve core installation position 206, and a notch matching the clamping part is opened on one end face of the valve core 3 close to the water passing groove 301.

[0040] Specifically, as Figures 3-4 shown: When installing the valve core 3, only need to snap it into the valve core installation position 206, so that the water outlet hole 207 and the water inlet hole 208 on the valve core installation position 206 correspond to the water passing groove 301 of the valve core 3, and then it can be fixed in a positioning hole 103 on one side of the outer shell 1 through a screwing part to complete the installation of the valve core 3. To sum up, the method of installing and fixing the water outlet pipe 5 and the water inlet pipe 6 through the water-passing inner core 2 will not only not affect the normal use of the faucet, but also be more convenient and fast when assembling the water outlet pipe 5 and the water inlet pipe 6. And a valve core installation position 206 is arranged on one side of the water-passing inner core 2, and the shape and size of the valve core installation position 206 are adapted to the valve core 3. Through the valve core installation position 206, the valve core 3 and the water-passing inner core 2 can be closely attached, so that the connection relationship between the valve core 3 and the faucet is closer and the sealing effect is better.

[0041] As Figures 1-2 shown: It further includes a water outlet pipe 5 and a water inlet pipe 6. The outer shell 1 is a three-way tubular shape. An upper connection hole 101 matching the water outlet end 204 is arranged at the upper end of the outer shell 1. The water outlet pipe 5 is hermetically connected to the water outlet end 204 through the upper connection hole 101. A lower connection hole 102 matching the water inlet end 205 is arranged at the lower end of the outer shell 1. The water inlet pipe 6 is hermetically connected to the water inlet end 205 through the lower connection hole 102. A positioning hole 103 matching the valve core installation position 206 is arranged on one side of the outer shell 1. The valve core 3 is installed on the valve core installation position 206 through the positioning hole 103.

[0042] In this embodiment, as Figures 9-10As shown in the figure: The outer surface of the upper connection hole 101 is provided with an external thread. When the water outlet pipe 5 extends and is fixed into the water outlet end 204, the sealing ring in the sealing groove at the lower end of the water outlet pipe 5 is compressed and sealed with the inner wall of the water outlet end 204. Then, the cover body sleeved on the water outlet pipe 5 is fixed to the upper connection hole 101 by means of threaded connection, thereby fixing the water outlet pipe 5 in the water outlet end 204. The water inlet pipe 6 is connected to the water inlet end 205 through the lower connection hole 102, and the sealing ring in the sealing groove of the water inlet pipe 6 is compressed and sealed with the inner wall of the water inlet end 205.

[0043] At the same time, as Figures 7-8 shown in the figure: The upper connection hole 101 may not be provided with an external thread. Instead, a notch matching the water outlet pipe 5 is directly opened at the top end of the outer shell 1, and the water outlet pipe 5 is fixed in the water outlet end 204 by means of compression sealing with a sealing ring through the notch.

[0044] As Figures 11-12 shown in the figure: The outer surface of the water passing inner core 2 is provided with a bone row type reinforcing rib 209 that fits closely with the inner wall of the outer shell 1. Axial positioning surfaces 210 are formed at the upper and lower ends of the valve core installation position 206, and the axial positioning surfaces 210 protrude from the valve core installation position 206.

[0045] As Figures 10-12 shown in the figure: A positioning notch 104 is opened on one side of the inner side of the outer shell 1 near the upper connection hole 101. A positioning block 211 matching the positioning notch 104 is provided at the upper end of the water passing inner core 2. When the water passing inner core 2 is installed in the outer shell 1, the positioning block 211 is inserted into the positioning notch 104, and the positioning block 211 is integrally formed at the upper end of the water passing inner core 2.

[0046] By providing a bone row type reinforcing rib 209 on the outer surface of the water passing inner core 2 that fits closely with the inner wall of the outer shell 1, axial positioning surfaces 210 are provided at the upper and lower ends of the valve core installation position 206 on one side of the water passing inner core 2, and a positioning block 211 is provided above the water passing inner core 2. When the water passing inner core 2 is installed in the outer shell 1, the bone row type reinforcing rib 209 is in close contact with the inner wall of the outer shell 1, the axial positioning surfaces 210 are matched and fitted with the positioning holes 103 on one side of the outer shell 1, and at the same time, the positioning block 211 is installed in the positioning notch 104 in the outer shell 1 through interlocking positioning. In the above way, the water passing inner core 2 is firmly fixed in the outer shell 1, avoiding the situation of deviation and misalignment of the water passing inner core 2, and at the same time being able to support the locking force when the valve core is locked and prevent its relative rotation.

[0049] Installation threads for fixing the valve core 3 are provided on the inner wall of the positioning hole 103. The valve core 3 is installed in the positioning hole 103 through a screw connector 8. The screw connector 8 is a columnar body with external threads. The disassembly and replacement of the valve core 3 are more convenient through the threaded connection method.

[0050] As Figure 12 shown: A valve core positioning hole 212 is formed on the valve core installation position 206, and a positioning end matching the valve core positioning hole 212 is provided on the valve core 3. When installing the valve core 3, the positioning end at the bottom end of the valve core 3 is snapped into the valve core positioning hole 212, and the threaded connection method of the screw connector 8 and the positioning hole 103 can enhance the connection relationship between the valve core installation position 206 and the valve core 3, thereby improving the stability between the two.

[0051] As Figures 1-2 shown: It further includes an outer housing 12. The outer housing 12 is sleeved outside the screw connector 8. By setting the outer housing 12, internal threads matching the external threads of the screw connector 8 are provided on the inner wall of the outer housing 12. The outer housing 12 covering outside the screw connector 8 through the threaded connection method can achieve the technical effects of protecting the screw connector 8 and increasing the aesthetic appearance.
