Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1-3, an embodiment provided by the present utility model: a stink-proof valve device for the sewage outlet of a straight-through toilet, an annular block 1, a rigid plastic pipe 9 is fixedly connected inside the annular block 1, a depth circular groove 17 is arranged inside the rigid plastic pipe 9, a groove 3 is arranged on one side of the annular block 1, a strong magnet 4 is embedded in the groove 3, a leak-proof rubber gasket 2 is fixedly connected to the annular block 1, a circular hole 16 is arranged inside the leak-proof rubber gasket 2, and the circular hole 16 communicates with the depth circular groove 17. A connecting block 5 is fixedly connected to one side of the annular block 1, a rotating shaft 6 is rotatably connected to the middle of the connecting block 5, a rotating block 7 is fixedly connected to the rotating shaft 6, an extension block 13 is fixedly connected to the middle of the inner side of the rotating block 7, a groove 14 is arranged on the extension block 13, and a strong magnet 15 is embedded in the groove 14. A fixing block 8 is fixedly connected to one side of the rotating block 7, a connecting rod 12 is fixedly connected to the side of the fixing block 8 away from the rotating block 7, a sealing ring 10 is fixedly connected to the outer surface of the rigid plastic pipe 9, a baffle 11 is fixedly connected to the side of the connecting rod 12 away from the fixing block 8. There are two groups of connecting blocks 5 and they are symmetrically distributed. The strong magnet 4 is magnetically connected to the strong magnet 15. There are two groups of leak-proof rubber gaskets 2, strong magnets 4, grooves 14, and strong magnets 15 and they are symmetrically distributed. There are two groups of fixing blocks 8 and connecting rods 12 and they are symmetrically distributed. Connect the leak-proof rubber gasket 2 to the drain outlet of the straight-through toilet, place the rigid plastic pipe 9 in the drain pipe. When the toilet flushes, when the flush button is pressed, the water in the water tank will quickly flow into the sewage outlet of the toilet, forming a strong water flow impact force. The water flow squeezes the baffle 11, and the baffle 11 drives the connecting rod 12, the fixing block 8, and the rotating block 7 to rotate and open along the rotating shaft 6, so that the water flows into the drain pipe from the opened baffle 11. After the water has flowed out, the strong magnet 4 magnetically attracts the strong magnet 15, causing the extension block 13 to drive the rotating block 7, the fixing block 8, the connecting rod 12, and the baffle 11 to rotate along the rotating shaft 6, and the baffle 11 rotates back to its original position to block the bottom of the rigid plastic pipe 9, effectively preventing the backflow of odors after the straight-through toilet drains, effectively improving the air quality in the room, and thus improving the mood of the user when using the straight-through toilet.

[0030] The baffle cover 11 is arranged below the rigid plastic pipe 9. The rigid plastic pipe 9 is composed of a surface layer 18, a strengthening layer 19, and an anti-corrosion layer 20. The lower surface of the surface layer 18 is fixedly connected to the strengthening layer 19. The lower surface of the strengthening layer 19 is fixedly connected to the anti-corrosion layer 20. The strengthening layer 19 is arranged between the surface layer 18 and the anti-corrosion layer 20. The surface layer 18 is mixed with polyethylene material. The strengthening layer 19 is composed of aramid fiber materials. The anti-corrosion layer 20 is mixed with polyvinyl chloride material. Since the surface layer 18 is mixed with polyethylene material, the odor-proof valve has excellent anti-aging, anti-impact, and wear-resistant properties. Since the strengthening layer 19 is composed of aramid fiber materials, the odor-proof valve has excellent tensile, bending, and shear mechanical properties, as well as corrosion resistance and flame retardancy. Since the anti-corrosion layer 20 is mixed with polyvinyl chloride material, the odor-proof valve has excellent physical and chemical properties, chemical corrosion resistance, high impact strength, small fluid resistance, and aging resistance, etc., which can increase its long service life.

[0031] Working principle: First, connect the leak-proof rubber gasket 2 to the drain outlet of the straight-through toilet. Place the rigid plastic pipe 9 in the drain pipe. When the toilet flushes and the flush button is pressed, the water in the water tank will quickly flow into the sewage outlet of the toilet, forming a strong water flow impact force. The water flow squeezes the baffle cover 11. The baffle cover 11 drives the connecting rod 12, the fixed block 8, and the rotating block 7 to rotate and open along the rotating shaft 6, so that the water flows into the drain pipe from the opened baffle cover 11. When the water flow is finished, the strong magnet 1 attracts the strong magnet 2, causing the extension block 13 to drive the rotating block 7, the fixed block 8, the connecting rod 12, and the baffle cover 11 to rotate along the rotating shaft 6. The baffle cover 11 rotates back to its original position to block the bottom of the rigid plastic pipe 9, effectively preventing the backflow of odors after the straight-through toilet drains, effectively improving the indoor air quality, and thus improving the user's mood when using the straight-through toilet. Since the surface layer 18 is mixed with polyethylene material, the odor-proof valve has excellent anti-aging, anti-impact, and wear-resistant properties. Since the strengthening layer 19 is composed of aramid fiber materials, the odor-proof valve has excellent tensile, bending, and shear mechanical properties, as well as corrosion resistance and flame retardancy. Since the anti-corrosion layer 20 is mixed with polyvinyl chloride material, the odor-proof valve has excellent physical and chemical properties, chemical corrosion resistance, high impact strength, small fluid resistance, and aging resistance, etc., which can increase its long service life.
