[0028] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0029] like Figure 1 and Figure 10As shown, this utility model provides a faucet valve seat assembly structure, including: a valve seat 14, which includes a valve seat body 1 and a positioning post 2. The positioning post 2 is connected to the front side of the upper end of the valve seat body 1. The upper end face and lower end face of the positioning post 2 respectively have two first clearance planes 5 and 6. The positioning post 2 includes a flange portion 3 and a positioning portion 4 connected to the front end of the flange portion 3. The positioning portion 4 extends radially outward relative to the flange portion 3, thereby forming a positioning step 8 relative to the flange portion 3; a connecting pipe section, which is disposed in the transverse pipe section 12 of the faucet body 15, located in front of the valve core hole 16 of the faucet body 15. The upper side and lower side face of the connecting pipe section respectively have two second clearance planes 9 and 10. The connecting pipe section includes a first pipe section 22 and a second pipe section 23 connected to the front end of the first pipe section 22. The diameter of the second pipe section 23 is increased relative to the first pipe section 22, thereby... A positioning plane is formed relative to the first pipe segment 22; wherein, the width of the positioning post 2 in the lateral direction is set such that: when the positioning post 2 enters the interior of the connecting pipe segment through the valve core hole 16, one side of the positioning post 2 moves into the interior of the connecting pipe segment through the valve core hole 16 and moves towards the inner wall of the second pipe segment 23, causing the other side of the positioning post 2 to enter the interior of the connecting pipe segment through the valve core hole 16; when the positioning post 2 is disposed in the interior of the connecting pipe segment, the flange 3 is embedded in the first pipe segment 22, the positioning part 4 is embedded in the second pipe segment 23, the positioning step 8 abuts against the positioning plane, the first clearance plane 5 of the upper end face of the positioning post 2 and the second clearance plane 9 of the upper side face of the connecting pipe segment are in contact with each other, and the first clearance plane 6 of the lower end face of the positioning post 2 and the second clearance plane 10 of the lower side face of the connecting pipe segment are in contact with each other.

[0030] The faucet body 15 includes a horizontal pipe section 12 and a vertical pipe section 13. A valve core 18 is installed inside the horizontal pipe section 12, and a top cover 19 is installed on the outside of the valve core 18. The valve core 18 assembly includes a valve seat 14, an outlet pipe 21, and an inlet pipe 20. Both the outlet pipe 21 and the inlet pipe 20 are connected to the lower part of the valve seat body 1, and the positioning pin 2 is connected to the upper front side of the valve seat body 1.

[0031] When using the faucet valve seat assembly structure provided by this utility model, firstly, the valve seat assembly is vertically installed into the vertical pipe section 13 of the faucet body 15. Once the valve seat 14 reaches the valve core hole 16, the first clearance plane 5 of the upper end face of the positioning post 2 and the second clearance plane 9 of the upper side face of the connecting pipe section are aligned with each other. Simultaneously, the first clearance plane 6 of the lower end face of the positioning post 2 is aligned with the second clearance plane 10 of the lower side face of the connecting pipe section. Then, the positioning post 2 is operated so that one side of the positioning post 2 (relative to the upper and lower end faces of the positioning post, which can be the left or right side of the positioning post) is positioned. Figure 5and Figure 6 The side of the positioning pin (corresponding to the lower side) first enters the connecting pipe section through the valve core hole 16, and moves this side of the positioning pin 2 towards the inner wall of the adjacent side of the second pipe section 23, causing the positioning pin 2 to tilt and rotate, thereby exposing enough space in the valve core hole 16 for the other side of the positioning pin 2 (relative to the upper and lower end faces of the positioning pin, which can be the left or right side of the positioning pin). Figure 5 and Figure 6 The positioning pin 2 passes through the upper side and enters the interior of the connecting pipe section. Next, the position of the positioning pin 2 is adjusted so that the flange 3 of the valve seat 14 mates with the first pipe section 22, the flange 3 is embedded inside the first pipe section 22, the positioning part 4 is embedded inside the second pipe section 23, and the positioning step 8 abuts against the positioning plane, thereby fixing the valve seat 14 on the faucet body 15. Based on the above process, by rotating the valve seat 14 left and right, the positioning pin 2 can be installed into the transverse pipe section 12 of the faucet body 15. The installation process is not affected by the position of the valve core hole 16, reducing the installation difficulty of the valve seat 14.

[0032] When removing the valve seat assembly, the valve seat assembly can be operated so that one side of the positioning column 2 moves closer to the inner wall of the adjacent side of the second pipe section 23, causing the positioning column 2 to rotate, thereby exposing enough space in the valve core hole 16 for the other side of the positioning column 2 to pass through the valve core hole 16 and detach from the connecting pipe section, and then one side of the positioning column 2 is allowed to pass through the valve core hole 16 again.

[0033] Here, the flange portion 3 and the positioning portion 4 of the positioning post 2 can be understood as two interconnected cylinders. The diameter of the positioning portion 4 is larger than the diameter of the flange portion 3. These two cylinders are simultaneously cut off at the top and bottom, thus forming the upper and lower end faces of the positioning post 2, which serve as the two first clearance planes 5 and 6 of the positioning post 2. That is, the upper end faces of the flange portion 3 and the positioning portion 4 together constitute the upper end face of the positioning post 2, and the lower end faces of the flange portion 3 and the positioning portion 4 together constitute the lower end face of the positioning post 2. The flange portion and the positioning portion can be arranged coaxially, as long as one side of the positioning post, after entering the second hole section, can avoid the inner wall of the second hole section on the same side, allowing the other side of the positioning post to also enter the second hole section.

[0034] In a preferred embodiment, in the faucet valve seat assembly structure, the positioning post 2 includes a positioning rib 7, the front end of which is connected to the rear end face of the positioning part 4, and one side of which is connected to the outer peripheral surface of the flange part 3; the first pipe section 22 is provided with a positioning groove 11; when the positioning post 2 is located inside the connecting pipe section, the positioning rib 7 is engaged in the positioning groove 11.

[0035] When the positioning pin 2 is installed in the connecting pipe section, the positioning rib 7 engages with the positioning groove 11, thereby preventing the valve seat 14 from rotating axially relative to the faucet body 15. That is, the positioning rib 7 and the positioning groove 11 cooperate to achieve axial positioning of the valve seat 14.

[0036] In a preferred embodiment, in the faucet valve seat assembly structure, the positioning post 2 includes two positioning ribs 7 symmetrically distributed relative to the flange portion 3.

[0037] The two positioning ribs 7 can be located on the left and right sides of the flange 3 respectively, and together they axially position the valve seat 14.

[0038] In a preferred embodiment, the faucet valve seat assembly structure further includes a pressure cap 17, which is disposed inside the second pipe section 23, connected to the second pipe section 23, and pressed against the front end face of the positioning post 2.

[0039] To further secure the valve seat 14, a pressure cap 17 is installed inside the second pipe section 23. This pressure cap 17 can lock and fix the positioning pin 2. When the valve core 18 needs to be replaced, the pressure cap 17 can be removed, and then the valve seat 14 can be removed from the faucet body 15.

[0040] In a preferred embodiment, in the faucet valve seat assembly structure, the inner wall of the second pipe section 23 has an internal thread, and the outer peripheral surface of the pressure cap 17 has an external thread 24. The external thread 24 is threadedly connected to the internal thread, thereby connecting the pressure cap 17 to the connecting pipe section.

[0041] The valve core 18 inside the transverse pipe section 12 can be installed at the front end of the gland 17, and the front end of the valve core 18 is pressed by the upper cover 19.

[0042] In a preferred embodiment, the valve seat 14 in the faucet valve seat assembly structure is made of plastic.

[0043] The valve seat 14 is made of engineering plastic, which does not contain trace elements that are harmful to the human body, making it more environmentally friendly and ensuring water safety.

[0044] In a preferred embodiment, the valve seat 14 in the faucet valve seat assembly structure is an integrally formed structure.

[0045] The valve seat 14 is made of engineering plastic and can be directly molded as a single piece, which is convenient for processing and molding.

[0046] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
