[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0039] This application discloses a faucet with a universal valve core seat. (Refer to...) Figure 1 and Figure 2 A faucet with a universal valve core seat includes a faucet housing 1, a valve core seat 2 arranged inside the faucet housing 1, a water outlet valve core 3 installed on the top of the valve core seat 2, and a limiting member 4 that presses the water outlet valve core 3 against the top surface of the valve core seat 2.

[0040] Reference Figure 2 The faucet housing 1 includes a cylindrical main body shell 11 and a water outlet shell 12 connected and fixed to the cylindrical main body shell 11. The cylindrical main body shell 11 has an installation chamber inside, and a support partition 111 fixed to the cylindrical main body shell 11 and used to support the bottom surface of the valve core seat 2 is arranged inside the installation chamber. An operating groove 112 is provided at the connection between the installation chamber and the water outlet pipe chamber of the faucet housing 1. The operating groove 112 has an arc-shaped structure, providing a larger operating space and facilitating the installation and maintenance of the water outlet valve core 3 and the valve core seat 2.

[0041] Reference Figure 2 The faucet housing 1 also includes a handle housing 13 on the upper side of the columnar main body housing 11 and connected to the top of the water outlet valve core 3. By lifting and rotating the handle housing 13, the top of the water outlet valve core 3 is lifted and rotated, thereby switching the internal structure of the water outlet valve core 3 and allowing the required water to flow out.

[0042] Reference Figure 2 and Figure 3 The valve core seat 2 has a first through hole 21 corresponding to the cold water inlet 31 of the outlet valve core 3, a second through hole 22 corresponding to the hot water inlet 32 ​​of the outlet valve core 3, and an outlet channel 23 corresponding to the outlet 33 of the outlet valve core 3; the valve core seat 2 is also equipped with an outlet pipe 5 connected to the outlet channel 23, and the outlet pipe 5 is arranged in the outlet pipe cavity of the connecting installation chamber provided inside the outlet outer shell 12 of the faucet housing 1.

[0043] Reference Figure 3The first through hole 21 of the valve core seat 2 includes a first section 211 connected to the lower cold water pipe 6 and a second section 212 connected to the cold water inlet 31 of the outlet valve core 3; the axis of the first section 211 is off-axis from the axis of the second section 212. The second through hole 22 includes a third section 221 connected to the lower hot water pipe 7 and a fourth section 222 connected to the hot water inlet 32 ​​of the outlet valve core 3; the axis of the third section 221 is off-axis from the axis of the fourth section 222. The bottom of the second section 212 has a first water guide surface 2121 inclined towards the cold water inlet 31 of the outlet valve core 3; the bottom of the fourth section 222 has a second water guide surface 2221 inclined towards the hot water inlet 32 ​​of the outlet valve core 3. The off-axis arrangement allows water in the cold water pipe 6 to flow through the second orifice 212, pass through the first guide surface, enter the first orifice 211, and then enter the cold water inlet 31 of the outlet valve core 3; water in the hot water pipe 7 can flow through the fourth orifice 222, pass through the second guide surface, enter the third orifice 221, and then enter the hot water inlet 32 ​​of the outlet valve core 3.

[0044] Reference Figure 2 and Figure 4 Water is discharged from the outlet 33 of the outlet valve core 3 and enters the outlet channel 23 of the valve core seat 2. The outlet channel 23 includes an arrangement through hole 232 radially arranged on the valve core seat 2 and penetrating the side wall, and an outlet through hole 231 opened on the top surface of the valve core seat 2 and communicating with the arrangement through hole 232. The outlet through hole 231 passes through the valve core seat 2 above the arrangement through hole 232 and communicates with the outlet 33 on the outlet valve core 3, so that the water discharged from the outlet 33 can flow into the arrangement through hole 232 through the outlet through hole 231. The arrangement through hole 232 has a sealing end 2321 and an outlet end 2322. The valve core seat 2 is provided with a sealing plug 24 for sealing the sealing end 2321 of the arrangement through hole 232. The outlet pipe 5 is installed at the outlet end 2322. The sealing plug 24 seals the sealing end 2321 of the through hole 232, so that the water entering the through hole 232 flows out from the outlet end 2322 and into the outlet pipe 5 connected to the outlet end 2322.

[0045] Reference Figure 2 and Figure 4 The valve core seat 2 has a plug groove 25 for installing the water outlet pipe 5 at the outlet end 2322 of the through hole 232. The end of the water outlet pipe 5 has a sealing ring groove 511, and a sealing ring 512 is provided in the sealing ring groove 511 for circumferential sealing with the inner wall of the plug groove 25. The sealing ring 512 at the end of the water outlet pipe 5 seals the water outlet pipe 5 with the inner wall of the plug groove 25, so that the water flowing out of the outlet end 2322 of the through hole 232 can directly enter the water outlet pipe 5, and is less likely to leak from the sealed connection between the outlet end 2322 of the through hole 232 and the water outlet pipe 5, thus reducing the probability of water leakage.

[0046] Reference Figure 2 and Figure 4 The water outlet pipe 5 includes an inlet section 51 connected to an outlet end 2322 with a through hole 232 and an outlet section 52 for supplying water. An aerator 521 is provided at one end of the outlet section 52, allowing water in the outlet pipe 5 to be aerated by the aerator 521 before flowing out. An outlet mesh 53 is provided at the end of the outlet pipe 5, located on the inner wall of the outlet casing 12 outside the aerator 521, reducing the probability of external impurities entering the outlet pipe 5 and causing blockage.

[0047] Reference Figure 2 and Figure 5 The valve core seat 2 is also provided with a weight reduction groove 26 on its lower side. The weight reduction groove 26 reduces the weight of the valve core seat 2 and reduces the pressure of the valve core seat 2 on the bottom support plate 111. The valve core seat 2 is also provided with a clearance groove 251 on the outer side of the upper end of the insertion groove 25 to facilitate the smooth installation of the water outlet pipe 5 and related components.

[0048] Reference Figure 6 and Figure 7 The bottom surface of the outlet valve core 3 is provided with a limiting post 34, and the top surface of the valve core seat 2 is provided with two circumferentially arranged limiting grooves 27 for the insertion of the limiting post 34. During installation, the limiting post 34 on the bottom surface of the outlet valve core 3 is inserted into the limiting grooves 27 on the valve core seat 2 to achieve positioning. The bottom surface of the outlet valve core 3 is also provided with a sealing element for isolating the cold water inlet 31, the hot water inlet 32, and the outlet 33. When the cold water inlet 31 of the outlet valve core 3 is connected to the first through hole 21 of the valve core seat 2, the hot water inlet 32 ​​of the outlet valve core 3 is connected to the second through hole 22 of the valve core seat 2, and the outlet 33 of the outlet valve core 3 is connected to the outlet through hole 231 of the valve core seat 2.

[0049] Reference Figure 2 and Figure 8 The limiting component 4 includes a threaded tube 41 threaded to the top of the inner cavity of the faucet housing 1 and a clamping ring 42 connected to the bottom end of the threaded tube 41 for pressing the water outlet valve core 3. The threaded tube 41 has external threads on its outer circumference, which mate with the internal threads circumferentially located at the top of the inner cavity of the faucet housing 1 to form a tight threaded connection, enhancing the sealing effect. The clamping ring 42 connected to the bottom end of the threaded tube 41 has its lower bottom surface abutting against the upper top surface of the water outlet valve core 3. Through the rotation and fixation of the threaded tube 41, the clamping ring 42 continuously moves downwards, pressing the water outlet valve core 3 against the valve core seat 2.

[0050] The implementation principle of a faucet with a universal valve core seat in this application embodiment is as follows: When the water outlet valve core 3 leaks and needs to be replaced, the handle housing 13 and the limiting member 4 at the top of the faucet housing 1 are removed, the water outlet valve core 3 is taken out, and a suitable water outlet valve core 3 is replaced; the water outlet valve core 3 is pressed and installed on the valve core seat 2 by setting the limiting member 4; the support partition 111 set on the inner wall of the faucet housing 1 is used to support the valve core seat 2; the limiting post 34 at the bottom of the water outlet valve core 3 is inserted into the limiting groove 27 of the valve core seat 2, so that the valve core seat 2 and the water outlet valve core 3 are tightly installed, and the water outlet valve core 3 can be used smoothly.

[0051] When the handle housing 13 is lifted and rotated, water flows from the cold water pipe 6 into the first through hole 21, and then into the cold water inlet 31 of the outlet valve core 3. Water flows from the hot water pipe 7 into the second through hole 22, and then into the hot water inlet 32 ​​of the outlet valve core 3. After being mixed into a suitable water in the outlet valve core 3, the water enters the outlet through hole 231 on the valve core seat 2 through the outlet 33, then enters the arrangement through hole 232, and finally flows into the outlet pipe 5 for discharge.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
