[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] We know that the main components of the two-handle faucet in the prior art include a hot water regulating valve, a cold water regulating valve, and a faucet outlet pipe. Usually, the installation can be completed by completely assembling the above components on the countertop. The present invention is an improvement on the traditional two-handle faucet structure. It adopts a water channel component located below the countertop (i.e., a sinking installation) and a self-assembled component above the countertop. The self-assembled component above the countertop is called TRIM, which includes: a faucet outlet pipe, a valve body shell, and a handle for adjusting the valve core. When the valve core of the water channel component (hot water valve core and cold water valve core) is closed, the path with fluid pressure is cut off. At this time, the TRIM can be disassembled. Users can choose TRIMs with different surface colors or appearances according to their personal preferences for assembly without having to replace the water channel component already installed under the countertop, giving users a new experience.

The screw 63 is sleeved on one end of the screw 62, and the other end of the screw 62 passes through the connecting hole 14a and extends to the lower surface of the countertop 100. The upper end of the screw 63 abuts against the lower end of the connecting block 14. By rotating the adjusting screw 63, the connecting block 14 and the locking nut 61 are tightened toward each other, so that the hot water valve body 1 is fixed in the first mounting hole of the countertop 100.

[0061] As a further improvement, the locking assembly also includes a fixing plate 64 that is sleeved on the hot water valve body 1. The fixing plate 64 is in the shape of a hollow ring. A fixing hole 641 is provided at the lower end of the annular structure of the fixing plate 64. The upper end of the fixing plate 64 abuts against the lower surface of the countertop 100. The screw 63 is sleeved on one end of the screw rod 62. The other end of the screw rod 62 passes through the connecting hole 14a and extends to the fixing hole 641 of the fixing plate 64. The adjusting screw 63 is rotated, and the connecting block 14 and the locking nut 61 are tightened toward each other, so that the hot water valve body 1 is fixed in the first mounting hole of the countertop 100.

[0062] It should be noted that the locking and mounting structure of the locking nut 61, screw 62, screw 63 and fixing plate 64 on the cold water valve body 2 and the intermediate body 51 is the same as the locking and mounting structure of the hot water valve body 1 described above, and will not be repeated here.

[0063] As shown in Figures 5, 8, 9 and 10, a first external thread 15 is provided on the upper portion of the hot water valve body 1, and a second external thread 16 is provided near the first connection port 11. The connection between the first external thread 15 and the second external thread 16 has an annular step 17. The diameter of the first external thread 15 is larger than the diameter of the second external thread 16. The first external thread 15 is threadedly connected to the locking nut 61. The lower end of the locking nut 61 is tightly attached to the upper surface of the table 100. The second external thread 16 is used for threaded connection to the valve body housing 91. It should be noted that the structure of the cold water valve body 2 is the same as that of the hot water valve body 1.

[0064] As shown in Figures 9 and 10, the water channel assembly 200 of the present invention and the locking assembly for fixing the water channel assembly 200 can be pre-installed on the countertop 100. Most of the water channel assembly 200 is located below the countertop 100. The first interface 11 of the hot water valve body 1, the second interface 21 of the cold water valve body 2, and the pre-interface 51a of the intermediate body 51 in the water channel assembly 200 extend from the first mounting hole, the second mounting hole and the upper surface of the countertop 100 respectively. The core shaft of the hot water valve core 3 in the hot water valve body 1 extends upward from the first interface 11 and is connected to the handle, and the core shaft of the cold water valve core 4 in the cold water valve body 2 extends upward from the second interface 21 and is connected to the handle. The pre-interface 51a of the intermediate body 51 is connected to the faucet pipe body 93 and is locked and fixed by a top screw set in the connecting hole 51b.

[0065] The advantage of this embodiment 1 is that when the hot water valve core and the cold water valve core are closed, the faucet components located on the upper surface of the countertop, including the handle, valve body shell and faucet tube body, can be replaced or repaired by the user as needed, which is very convenient.

[0066] Example 2

[0067] Referring to Figures 11, 12, 13, and 14, the structure of Example 2 is largely identical to that of Example 1. The difference lies in the use of screws 62a, which replace the threaded rod, screws, and fixing plates of Example 1. Simply insert one end of screw 62a through the connection hole of the connecting block 14 of the hot water valve body 1 and extend it into the screw hole 62b on the lower surface of the countertop 100. Tightening screw 62a tightens the connecting block 14 of the hot water valve body 1 and the locking nut 61 toward each other, securing the hot water valve body 1 in the first mounting hole of the countertop 100. The cold water valve body 2 has the same structure as the hot water valve body 1 and is secured with screws 62a. This advantageously reduces the number of components, faucet installation becomes more convenient, and production costs are reduced.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
