[0033] Embodiment 1

[0034] Reference Figures 1 to 11 As shown, a water outlet faucet provided in this embodiment includes a faucet housing 21, a thermostatic valve 22 and a faucet mounting seat 10. The faucet mounting seat 10 is used to be mounted on a basin 1 and is provided with a mounting through hole 111 and a plurality of water passages 101. In this specific embodiment, there are four water passages 101, namely, a cold water passage, a hot water passage and two water outlet passages. Of course, other embodiments are not limited thereto. The mounting through hole 111 is used to penetrate a water outlet pipe. The faucet housing 21 is mounted on the faucet mounting seat 10. The thermostatic valve 22 is arranged on the faucet housing 21. The thermostatic valve 22 has a docking housing 25. The docking housing 25 has a positioning column 251 and a plurality of water inlets 252. Specifically, there are four water inlets 252, two inlets and two outlets. The positioning column 251 is inserted into the mounting through hole 111 of the faucet mounting seat 10 to achieve positioning. The plurality of water inlets 252 and the plurality of water passages 101 of the faucet mounting seat 10 correspond to each other and form a connection.

[0035] Specifically, the positioning column 251 also has a hole for passing the water outlet pipe.

[0036] A docking shell 25 is provided on the temperature regulating valve 22, and a positioning column 251 is provided on the docking shell 25. When the faucet shell 21 is assembled on the faucet mounting seat 10, the positioning is achieved by inserting the positioning column 251 into the mounting through hole 111 of the faucet mounting seat 10, so that the water inlet 252 and the water passage 101 of the faucet mounting seat 10 are accurately aligned, and the operation is greatly simplified; at the same time, the existing mounting through hole 111 on the faucet mounting seat 10 is used for passing the water pipe and guiding at the same time, with minor changes and ingenious design; for example, the faucet mounting seat 10 can continue to use the existing structure, saving costs, especially mold development costs.

[0037] Further preferably, a sealing gasket 23 is provided between the docking housing 25 and the faucet mounting seat 10, and a sealing fit is achieved through the sealing gasket 23; a clearance through hole 231 and a plurality of water holes 232 are formed on the sealing gasket 23, the positioning column 251 passes through the clearance through hole 231 and is positioned and matched with the mounting through hole 111, and the corresponding water inlet 252 and the water channel 101 are connected through the water holes 232. The structure of the sealing gasket 23 can achieve a good sealing fit and effectively prevent problems such as water leakage.

[0038] Specifically, on the upper surface of the sealing gasket 23, the sealing gasket 23 has a sealing ring 233 protruding from the periphery of the water hole 232, and the sealing ring 233 is inserted into the water inlet 252, thereby achieving a large-area sealing contact with the inner wall of the water inlet 252, and the sealing effect is better.

[0039] At the same time, on the lower surface of the sealing gasket 23 , the sealing gasket 23 has a sealing ring 234 protruding from the outer periphery of the water hole 232 , and is sealed against the faucet mounting base 10 through the sealing ring 234 , thereby achieving a sealed connection between the water hole 232 and the water channel 101 .

[0040] With such arrangement, the sealing connection effect of each channel is better. Of course, in other embodiments, the upper surface and the lower surface of the sealing gasket 23 can also be a sealing ring 233, or can also be a sealing ring 234; or other sealing matching structures can be used instead.

[0041] Furthermore, an upper fixing ring 24 and a lower fixing ring 26 are fixed in the faucet housing 21, and the sealing gasket 23 is fixedly clamped between the upper fixing ring 24 and the lower fixing ring 26, so that the sealing gasket 23 is fixedly assembled. Specifically, the upper fixing ring 24 and the lower fixing ring 26 are both screwed in the faucet housing 21, with a simple structure and easy disassembly and assembly. Of course, other fixing methods can also be used for assembly in other embodiments.

[0042] Specifically, in this embodiment, the faucet mounting seat 10 includes a mounting seat body 11, an upper fixing portion 16 and a lower fixing portion 15. The mounting seat body 11 is inserted into the mounting hole of the basin 1. The mounting through hole 111 and a plurality of water passages 101 are formed on the mounting seat body 11. The mounting seat body 11 has a lower portion located at the bottom of the basin 1 and an upper portion extending from the surface of the basin 1. The lower fixing portion 15 is assembled to the lower portion of the mounting seat body 11 and abuts against the bottom surface of the basin 1. The upper fixing portion 16 is assembled to the upper portion of the mounting seat body 11 and abuts against the surface of the basin 1. The faucet housing 21 is fixedly assembled to the upper fixing portion 16. In this way, the faucet mounting seat 10 and the basin 1 are stably mounted.

[0043] Specifically, the upper fixing portion 16 includes a threaded abutment sleeve 161, which is threadedly connected to the top (ie, the upper part) of the mounting seat body 11 and abuts against the surface of the basin 1. The threaded assembly of the threaded abutment sleeve 161 is simple to assemble and disassemble.

[0044] Further preferably, the upper fixing portion 16 further includes a plurality of abutment bolts 162 threadedly connected to the threaded abutment sleeve 161, and the abutment bolts 162 are tightened to abut against the surface of the basin 1. After the threaded abutment sleeve 161 is tightened, the abutment bolts 162 are tightened to make the abutment bolts 162 press against the surface of the basin 1. This can better secure the faucet mounting base 10 to the basin 1 without loosening, and the firmness is better.

[0045] The faucet housing 21 is screwed and fixed on the threaded abutment sleeve 161. Specifically, a nut sleeve 211 is provided at the bottom of the faucet housing 21, and the outer peripheral surface of the threaded abutment sleeve 161 is also provided with an external thread that matches the nut sleeve 211.

[0046] Of course, in other embodiments, the structure of the upper fixing portion 16 is not limited thereto, and it can be replaced by fixing a component of the mounting seat body by means of a snap fastener or the like.

[0047] The lower fixing portion 15 includes an abutting gasket 152 and at least two abutting screws 151. In this embodiment, there are two abutting screws 151. Of course, in other embodiments, the number of abutting screws 151 can also be set to three or more. The two abutting screws 151 are respectively screwed on the opposite sides of the mounting seat body 1, such as the left and right sides. The abutting gasket 152 is arranged above the abutting screw 151, and the two abutting screws 151 are both pressed against the abutting gasket 152, so as to press against the bottom surface of the basin 1 through the abutting gasket 152. With the setting of the abutting gasket 152, the two abutting screws 151 directly act on the abutting gasket 152, and then evenly act on the bottom surface of the basin 1 through the abutting gasket 152, so that the abutting force is more balanced and will not wear the basin 1. Of course, in other embodiments, the structure of the abutting gasket 152 may not be adopted.
