In one embodiment, the first pipe section is connected to a drinking water supply pipe of a drinking water device, such as a silicone tube, and the drinking water supply pipe is sleeved on the outer surface of the first pipe section for inputting normal temperature drinking water into the faucet pipe 1. The present disclosure does not limit the outer diameter of the annular protrusion 13. In one embodiment, the outer diameter of the annular protrusion 13 is greater than or equal to 13 mm and less than or equal to 13.6 mm. By providing the annular protrusion 13, the friction between the drinking water supply pipe sleeved on the outer wall of the faucet pipe 1 and the faucet pipe 1 is increased, so that the connection between the two is more secure, and the drinking water supply pipe is prevented from sliding or falling off under the impact of water flow or other external forces.
[0040] like Figure 1 The sterilization device 2 includes a heating body 21 and a heat-insulating layer 22. The heat-insulating layer 22 is arranged on the outer surface of the heating body 21 to isolate the heat generated by the heating body 21; the heating body 21 is sleeved on the outer wall of the second pipe segment to heat the second pipe segment to a preset temperature. The present disclosure does not limit the material of the heat-insulating layer 22. In one embodiment, the heat-insulating layer 22 can be metal foil, ceramic fiber, glass fiber, etc., which can effectively reflect and block heat transfer and reduce heat loss to achieve energy saving and prevent scalding. The present disclosure does not limit the preset temperature. In one embodiment, the preset temperature is greater than or equal to 80°C. The preset temperature is greater than or equal to 80°C to ensure that the heating body 21 can reach a sufficiently high temperature, thereby effectively killing bacteria on the inner wall of the second pipe segment and the water outlet, thereby improving the reliability and effectiveness of the sterilization effect.
[0041] By heating the second pipe section to a preset temperature through the heating body 21, bacteria attached to the inner wall of the second pipe section and the water outlet 12 can be effectively killed; the insulation layer 22 arranged outside the heating body 21 can effectively isolate the heat generated by the heating body 21 and prevent the heat from being transferred to the faucet housing 3, thereby improving the energy utilization rate and the safety of the faucet mechanism. The heat acts concentratedly on the second pipe section, thereby improving the sterilization effect.
[0042] In one embodiment, the sterilization device 2 further includes a heat preservation layer 23, which is disposed on the outer surface of the heat insulation layer 22 and is used to insulate the heat generated by the heating body 21. The present disclosure does not limit the material of the heat preservation layer 23. In one embodiment, the heat preservation layer 23 can be polyurethane foam, polystyrene foam, polyurethane, etc. The heat preservation layer 23 is disposed on the outer surface of the heat insulation layer 22, which can effectively insulate heat, further prevent the heat generated by the heating body 21 from being lost, help maintain the temperature around the heating body 21 stable, and improve the heating efficiency and energy utilization rate.

Figure 3 The heating body 21 includes a heat transfer body 211 and a heating wire 212. The heating wire 212 is evenly distributed on the inner surface of the heat transfer body 211. The heat transfer body 211 is a flexible heat-conducting material. The heating wire 212 is used to heat the second pipe segment to a preset temperature when powered on. The present disclosure does not limit the distribution method of the heating wire 212. It is sufficient to ensure that the heating wire 212 is evenly distributed on the inner surface of the heat transfer body 211. In one embodiment, the heating wire 212 is distributed in a serpentine shape on the inner surface of the heat transfer body 211, and each inflection point of the serpentine distribution is transitioned through a right angle or a U shape. The heat transfer body 211 is made of a flexible heat-conducting material and has plasticity, which ensures that the heating body 21 can flexibly adapt to faucet pipes 1 of different shapes, and at the same time can ensure that heat is quickly transferred to the second pipe segment to effectively perform sterilization work; the heating wire 212 is evenly distributed on the inner surface of the heat transfer body 211, and heat can be evenly transferred to each part of the second pipe segment, thereby improving heating efficiency and stability.
[0044] like Figure 1 The faucet housing 3 is sleeved on the outer surface of the sterilizing device 2, and a first through hole is provided at the first end of the faucet housing 3, so that the faucet pipe 1 passes through the first through hole and is fixedly connected to the faucet housing 3. The present disclosure does not limit the material of the faucet housing 3. In one embodiment, the faucet housing 3 is made of polyphenylene sulfide (PPS), which has strong corrosion resistance and high temperature resistance. The design of the faucet housing 3 enables the faucet pipe 1 to pass through the first through hole and be firmly connected to the faucet housing 3, thereby ensuring the stability of the structure and facilitating installation and maintenance.
[0045] Figure 4 FIG. 2 shows a schematic diagram of the external structure of a sterilizing water nozzle mechanism according to an embodiment of the present disclosure. Figure 4 , a limiting plate 14 is provided on the outer wall of the faucet pipe 1, and a second through hole is provided on the limiting plate 14, which is used to allow the faucet pipe 1 to pass through the second through hole and be fixedly connected to the limiting plate 14; a slot matching the limiting plate 14 is provided on the first end of the faucet housing 3, which is used to limit the position of the faucet pipe 1, so that the sterilization device 2 is fixed between the faucet housing 3 and the faucet pipe 1. The present disclosure does not limit the shape of the limiting plate 14, and the limiting plate 14 can be clamped on the faucet housing 3. In one embodiment, the limiting plate 14 is fan-shaped. By limiting the position of the faucet pipe 1, it is ensured that the sterilization device 2 is fixed between the faucet housing 3 and the faucet pipe 1 to prevent it from moving or swaying during use, thereby ensuring the stability and effectiveness of the sterilization effect; by matching the slot on the faucet housing 3 with the limiting plate 14, the assembly process is made simpler.
[0046] like Figure 4 The first end of the faucet housing 3 is provided with a boss 31 for determining the installation direction of the faucet housing 3. The boss 31 provided at the first end of the faucet housing 3 can clearly indicate the installation direction, ensuring that the user or installer can quickly and accurately determine the correct position of the faucet housing 3 during installation, thereby simplifying the installation process and improving the installation efficiency. Figure 1 The second end of the faucet housing 3 is provided with a first extension portion 32 extending inwardly for fixing the faucet pipe 1. The first extension portion 32 extending inwardly provided at the second end of the faucet housing 3 provides a stable fixing structure for the faucet pipe 1.
[0047] like Figure 1-Figure 2 , an annular groove 16 is provided on the outer side of the edge of the water outlet 12, which is used to install the end of the heating body 21 in the annular groove 16. Through the annular groove 16, the end of the heating body 21 can be installed in the annular groove 16, thereby ensuring the firm fixation of the heating body 21, which helps to improve the effectiveness and safety of the heating body 21. A second extension portion 17 extending outward is provided at the top of the annular groove 16, and the second extension portion 17 is clamped above the first extension portion 32, which is used to fix the faucet pipe 1 in the faucet housing 3. By clamping the second extension portion 17 at the top of the annular groove 16 above the first extension portion 32, the faucet pipe 1 can be firmly fixed in the faucet housing 3, ensuring that the sterilization device 2 is fixed between the faucet pipe 1 and the faucet housing 3, preventing it from moving or loosening during use, and improving the stability and reliability of the sterilization effect.
[0048] Figure 5 FIG. 1 is a schematic diagram showing a cross-sectional structure of a faucet pipe according to an embodiment of the present disclosure. In one embodiment, the second pipe section includes a first portion 18 and a second portion 19. Figure 5 , along the flow direction of water in the faucet pipe 1, the inner diameter of the first part 18 gradually decreases, and the inner diameter of the second part 19 is smaller than the inner diameter of the first part 18. In one embodiment, the inner diameter of the front 1 / 2 section of the second part 19 gradually decreases, and the inner diameter of the rear 1 / 2 section remains unchanged. The present disclosure does not limit the inner diameter of the faucet pipe 1. In one embodiment, the inner diameter of the faucet pipe 1 is greater than or equal to 7 mm and less than or equal to 8.75 mm. The gradual reduction in the inner diameter can increase the speed of the water flow and help improve the water outlet efficiency of the faucet pipe 1; the inner diameter of the second part 19 is smaller than the inner diameter of the first part 18, which ensures that the water flow at the water outlet 12 is more concentrated, reduces the scattering of the water flow, and improves the user experience of the faucet mechanism.
[0049] like Figure 5The inner wall of the second part 19 is evenly provided with a plurality of guide ribs 15, and the guide ribs 15 extend from the connection position between the first part 18 and the second part 19 to the water outlet 12. The guide ribs 15 can effectively guide the water flow to flow more evenly to the water outlet 12, thereby reducing the bad water outlet phenomena such as bifurcation or splashing of the water flow at the water outlet 12.
[0050] The disclosed embodiment also provides a drinking water device including the above-mentioned sterilizing faucet mechanism, the drinking water device includes a fixing bracket, the fixing bracket can be a part of the drinking water device frame or a water baffle, in one embodiment, the fixing bracket is fixedly connected to the faucet housing 3 by screws, and the fixing bracket is provided with a through hole for the faucet pipe 1 to pass through, a through hole for the power cord of the heating body 21 to pass through, and a screw hole for the screw to pass through. Applying the sterilizing faucet mechanism to the drinking water device effectively reduces the growth of bacteria in the faucet pipe 1 and the water outlet 12, ensures the hygiene of drinking water, and improves the user's drinking experience.
