[0045] In conjunction with the accompanying drawings Figure 1 As shown, when in use, the switch shaft 11 is arranged inside the middle control valve core 9 of the limit valve 8, as shown in FIG. Figure 5As shown, the switch shaft 11 passes through the electric heating box 13 arranged inside the limit valve 8, and the grooves arranged at the bottom end of the electric heating box 13 are used to clamp the two sides of the switch shaft 11. Heat insulation cotton is arranged on the surface of the switch shaft 11 to isolate it from contact with the electric heating box 13. When in use, the electric heating box 13 is provided with a heating wire to heat the water contained in the filter tank 14 inside the electric heating box 13. Symmetrical activated carbon or high-temperature resistant resin filter materials are directly placed inside the filter tank 14 as needed to facilitate further treatment of the water. The child lock rotates the switch shaft 11, so that the switch shaft 11 lifts the blocking rod 10, and the water flows into the bottom opening of the electric heating box 13 through the gap at the bottom end of the control valve core 9 through the bottom opening of the limit valve 8. The switch shaft 11 simultaneously pulls the push rod 12 to move the movable plate 16 downward, so that the limiting silicone rod 17 inside the movable plate 16 moves downward, as shown in FIG. Figure 2 As shown, the water flows upward through the electric heating box 13, and the electric heating box 13 is connected to the power system through a cable, so that the electric heating box 13 is used synchronously with the power on and off, and can be freely opened and closed in cold weather;

[0046] In some embodiments, in conjunction with the instructions Figure 1-7 As shown, the electric heating box 13 is placed inside the limit valve 8, a filter tank 14 is arranged inside the electric heating box 13, and the upper end of the electric heating box 13 is slidably connected with the docking silicone 15, the upper end of the docking silicone 15 is installed and connected with the movable plate 16, and the bottom end of the movable plate 16 is snap-connected with the top of the push rod 12, the movable plate 16 is penetrated by the bottom end of the limit silicone rod 17, the limit silicone rod 17 is installed on the bottom end surface of the water distribution network 20, and the water distribution network 20 is installed at the bottom end of the inner tube 19, the inner tube 19 is installed inside the pipe sleeve 18, and the top of the pipe sleeve 18 is connected with the positioning pipe 2 6 is connected by snap-fitting, a U-shaped cavity structure is arranged inside the inner tube 19, and the inner tube 19 is penetrated by the water inlet 21, and a one-way valve 22 is arranged at the bottom of the water inlet 21, an ultraviolet waterproof disinfection rod 23 is arranged inside the cavity of the inner tube 19, an activated carbon layer 24 is arranged on the periphery of the cavity of the inner tube 19, and a ceramic ring 25 is arranged on the top of the activated carbon layer 24, the top of the ceramic ring 25 is against the positioning tube 26, and a mesh plate ring 27 is arranged inside the positioning tube 26, the mesh plate ring 27 is connected with the water outlet pipe 28, and a foamer 29 is threadedly connected to one end of the water outlet pipe 28;

[0047] In conjunction with the accompanying drawings Figure 1 As shown, when in use, the water body is heated and initially sterilized inside the electric heating box 13. After the push rod 12 pushes the movable plate 16 downward, the docking silica gel 15 arranged at the bottom end of the movable plate 16 is adsorbed on the openings on both sides of the top of the electric heating box 13, as shown in FIG. Figure 2As shown, water enters the water-dividing net 20 at the bottom of the inner tube 19 in the pipe sleeve 18 through the docking silicone 15. Since the water-dividing net 20 has a hole structure inside, the particles generated during the heating process are reduced. The silicone sleeve set at the connection position of the limiting silicone rod 17 located inside the movable plate 16 is in a closed state, as shown in FIG. Figure 1 As shown, the circulation of water is effectively isolated, and the water passes through the cavity at the bottom of the inner tube 19, as shown in FIG. Figure 1 and Figure 7 As shown, the water body pushes the one-way valve 22 to enter the inner tube 19, or through the opening at the bottom end of the inner tube 19, the water body flows into the inner tube 19 in an arc shape through the water inlet 21, wherein the inner and outer double-layer pipe insulation material arranged at the top of the inner tube 19 is a high-temperature resistant transparent material. When in use, the ultraviolet waterproof disinfection rod 23 arranged inside the inner tube 19 is driven by electricity, so that the ultraviolet waterproof disinfection rod 23 irradiates the water body inside the inner tube 19, purifies and sterilizes the bacteria in the water body, and disinfects the inner tube 19 at the same time. The ceramic ring 25 located at the top of the ultraviolet waterproof disinfection rod 23 alleviates the influence of the heat generated by the ultraviolet waterproof disinfection rod 23 during operation on the water body. The water body is pushed into the positioning tube 26 through the activated carbon layer 24, so that the positioning tube 26 pushes the water body to the mesh plate circle 27, so that the mesh plate circle 27 is finally filtered, and the water body is discharged to the foamer 29 through the outlet pipe 28, and the foamer 29 is better used for energy-saving work on the water body.

[0048] Working principle: When using the self-purifying and sterilizing faucet, first connect the water inlet pipe 2 with the bottom end of the supporting tube 1, so that the water enters the quartz sand filter 5 through the water inlet pipe 2, passes through the multi-layer filtration inside the quartz sand filter 5 and passes through the air-permeable net 6, and finally filters and processes large particles of sand and gravel and other impurities with the filter cotton 7. Then, by rotating the switch shaft 11, lift the blocking rod 10 and lower the push rod 12, so that the docking silica gel 15 at the bottom end of the push rod 12 follows the top rod body of the electric heating box 13 and sticks to the top opening of the electric heating box 13, so that the water passes through the bottom opening of the limit valve 8 and enters the filter tank 14 inside the electric heating box 13, and the corresponding adsorption and filtration resin or The activated carbon material allows the water to pass through the electric heating box 13 and the docking silica gel 15 through the limiting silica gel rod 17 and enter the lower part of the inner tube 19 cavity, so that the water enters the upper end cavity of the inner tube 19 through the water inlet 21 and the impact one-way valve 22, and the water is further treated and sterilized by the ultraviolet waterproof disinfection rod 23 and the activated carbon layer 24. The heat of the ultraviolet waterproof disinfection rod 23 is relieved and cooled as the water enters the interior. The ceramic ring 25 located at the top of the ultraviolet waterproof disinfection rod 23 relieves the rapid increase in water temperature caused by the overheating of the ultraviolet waterproof disinfection rod 23. At the same time, the water passes through the mesh ring 27 inside the positioning tube 26 and flows out through the foamer 29 at the other end of the outlet pipe 28.
