[0023] The lower end outer wall of limit rod 13 and the lower end outer wall of locating rod 10 are both equipped with a lead-in taper surface 22, and the diameter of lead-in taper surface 22 gradually decreases from top to bottom.

[0024] The left side wall of valve core seat 8 is equipped with a left water delivery hole 23 that is through with the internal space, the right side wall of valve core seat 8 is equipped with a right water delivery hole 24 that is through with the internal space, and the lower end of valve core 3 is equipped with a water delivery channel 25, and left water delivery hole 23 and right water delivery hole 24 are through with water delivery channel 25.

[0025] The both sides of the upper surface of inner cover 15 are equipped with the bayonet 26 that is symmetrical with each other.

[0026] The outer wall of the part of valve core seat 8 in embedded hole 4 is equipped with a plurality of sealing grooves 27 that are evenly distributed in axial direction, and the sealing groove 27 is equipped with a sealing ring 28 that is matched with it.

[0027] The outer wall of the part of valve core 3 in valve core hole 11 is equipped with a annular groove 29, and the annular groove 29 is equipped with an O-shaped ring 30 that is matched with it.

[0028] The upper end outer wall of outer cover 20 is regular hexagon.

[0029] The use method of the utility model is as follows:

[0030] Since the valve core 3 is fixed in the valve core hole 11, and the valve core hole 11 is set on the valve core seat 8, which is embedded in the recess 4 of the faucet body 1, the valve core 3 can be removed at the same time simply by removing the valve core seat 8. The valve core 3 can be removed separately in any place with enough space, without having to remove it from the faucet body 1. This effectively avoids the situation where the removal of the valve core 3 must be done on the faucet body connected to the pipeline, which would limit the removal space due to the installation environment of the faucet body. When the valve core 3 can be removed separately, it is no longer limited by space, which can effectively ensure the removal efficiency.

[0031] If different models of valve cores are required during actual use, the valve core seat 8 can be directly removed from the recessed hole 4 of the faucet body 1, and then replaced with a valve core seat 8 with a valve core hole 11 of a different size. This allows the new model of valve core to be adapted to the new valve core hole. Throughout the replacement process, the faucet body 1 remains fixed to the pipeline system, effectively avoiding the need to replace different models of faucet body 1 when replacing different models of valve core 3. This also avoids wasting a lot of time by disassembling the faucet body 1 from the pipeline system, and effectively avoids increasing the replacement cost by replacing the entire faucet body 1.

[0032] When the valve core seat 8 needs to be removed from the recessed hole 4, since the second external thread 19 is located on the upper outer wall of the fixing part 18, and the outer cover 20 is screwed to the upper outer wall of the fixing part 18 through the second external thread 19, it is only necessary to rotate the outer cover 20 so that the outer cover 20 moves upward along the trajectory of the second external thread 19, and the outer cover 20 can be separated from the fixing part 18. At this time, the locking step 21 inside the outer cover 20 is no longer pressed tightly against the upper surface of the inner cover 15, and there is no longer any external force applied downward to the valve core seat 8 through the inner cover 15. The valve core seat 8 can then be pulled upward along the trajectory of the recessed hole 4, so that the valve core seat 8 and the valve core 3 are simultaneously separated from the recessed hole 4 on the faucet body 1.

[0033] When it is necessary to remove the valve core 3 from the valve core seat 8, since the first external thread 14 is located on the upper outer wall of the valve core seat 8, and the inner cover 15 is screwed to the upper outer wall of the valve core seat 8 through the first external thread 14, it is only necessary to rotate the inner cover 15 so that the inner cover 15 moves upward along the trajectory of the first external thread 14, and the inner cover 15 can be disengaged from the upper end of the valve core seat 8. At this time, the upper inner wall of the inner cover 15 is no longer pressed down on the limiting step 17 of the valve core 3. Then the valve core 3 can be pulled upward from the valve core hole 11 of the valve core seat 8 to complete the quick disassembly of the valve core 3.

[0034] The fit between the positioning rod 10 on the lower surface of the valve core seat 8 and the positioning hole 9 at the bottom of the recessed hole 4 enables quick positioning and installation when the valve core seat 8 is inserted into the recessed hole 4. Similarly, the fit between the limiting rod 13 on the lower surface of the valve core 3 and the limiting hole 12 at the bottom of the valve core hole 11 enables quick positioning and installation when the valve core 3 is inserted into the valve core hole 11. Both the lower outer wall of the limiting rod 13 and the lower outer wall of the positioning rod 10 are provided with an inlet cone surface 22. The diameter of the inlet cone surface 22 gradually decreases from top to bottom. The presence of the inlet cone surface 22 facilitates the quick insertion of the lower end of the positioning rod 10 into the positioning hole 9 and the quick insertion of the lower end of the limiting rod 13 into the limiting hole 12, further ensuring the efficiency of the installation of the valve core seat 8 and the valve core 3.

[0035] The valve core seat 8 has a left water inlet 23 that communicates with its internal space on the left side wall, and a right water inlet 24 that communicates with its internal space on the right side wall. The valve core 3 has a water inlet channel 25 at the lower end. The left water inlet 23 and the right water inlet 24 are connected through the water inlet channel 25. When the embedded hole 4 is located in the middle of the faucet body 1, if there is another water inlet device 31 on the right end of the faucet body 1 away from the water outlet connector 2, the water output by the water inlet device 31 can flow through the right water inlet 24, the water inlet channel 25, and the left water inlet 23 in sequence to the water outlet connector 2, and finally be output from the water outlet connector 2 for use.

[0036] The inner cover 15 has symmetrical latches 26 on both sides of its surface. The sheet structure can be simultaneously latched onto the latches 26 on both sides, and the inner cover 15 can be easily rotated through the sheet structure, which is convenient for the installation and removal of the inner cover 15.

[0037] The outer wall of the part of the valve core seat 8 located in the recess 4 is provided with several sealing grooves 27 that are evenly distributed axially. The sealing grooves 27 are provided with matching sealing rings 28. The presence of sealing rings 28 can effectively ensure the sealing between the outer wall of the valve core seat 8 and the inner wall of the recess 4, and prevent water leakage.

[0038] The outer wall of the part of the valve core 3 located inside the valve core hole 11 is provided with an annular groove 29, and an O-ring 30 matching it is provided in the annular groove 29. The presence of the O-ring 30 can effectively ensure the sealing between the outer wall of the valve core 3 and the inner wall of the valve core hole 11, and prevent water leakage.

[0039] The outer wall of the upper end of the outer cover 20 is a regular hexagon. Simply put the socket of the socket wrench on the upper end of the matching outer cover 20, and the outer cover 20 can be easily rotated by the socket wrench, which is convenient for the assembly and disassembly of the outer cover 20.
