Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a drainage interface device, such as Figures 1-4 As shown, the drainage interface device includes a housing 1, a sealing assembly is fixedly connected to the inner wall of the housing 1, and a reinforcing assembly is fixedly connected to both the upper and lower ends of the outer surface of the housing 1.

[0026] The sealing assembly includes a fixed plate 2, the outer surface of which is fixedly connected to the inner wall of the housing 1. A spring 3 is fixedly connected to the upper surface of the fixed plate 2, and a first sealing plate 4 is fixedly connected to the top of the spring 3. A push rod 5 penetrating the spring 3 is provided on the lower surface of the first sealing plate 4, and a second sealing plate 6 is fixedly connected to the bottom of the push rod 5. Water flow impacts the first sealing plate 4, and at the same time, the push rod 5 pushes the second sealing plate 6, causing both to move away from the sealing plate 7 simultaneously, thereby realizing the automatic opening of the drainage channel. The operation is convenient and easy to use. Subsequently, under the push of the spring 3, the first sealing plate 4 and the second sealing plate 6 automatically reset and tightly adhere to the sealing plate 7, effectively preventing sewage backflow. At the same time, a water storage area is formed inside the housing 1, which acts as a water seal, isolating the odor in the pipe and preventing the odor from escaping, thereby improving the overall sealing performance and environmental hygiene level.

[0027] Both the upper and lower surfaces of the housing 1 are provided with through grooves, and a sealing plate 7 is fixedly connected inside the through grooves.

[0028] The upper surface of the sealing plate 7 is provided with a conical groove that is compatible with the first sealing plate 4 and the second sealing plate 6. The outer surfaces of the first sealing plate 4 and the second sealing plate 6 are provided with rubber rings 8. The outer surface of the rubber rings 8 overlaps the inside of the conical groove. The conical groove facilitates the passage of water. The rubber rings 8 can improve the sealing performance of the first sealing plate 4 and the second sealing plate 6 when sealing the sealing plate 7.

[0029] The reinforcement component includes a fixing ring 9, the middle of which is fixedly connected to the top of the outer surface of the housing 1. Threaded rods 10 are fixedly connected to both sides of the inner wall of the fixing ring 9. Snap rings 11 are slidably connected to both sides of the outer surface of the threaded rods 10. A limit nut 12 is threadedly connected to the outer surface of the threaded rods 10 outside the snap rings 11. The fixing ring 9 is fixedly connected to the housing 1, which prevents the snap rings 11 from being lost. The snap rings 11 are then moved relative to the surface of the threaded rods 10, and the limit nut 12 is tightened to limit and fix the position of the snap rings 11, so that the snap rings 11 fit tightly against the connection between the external pipe and the device, effectively enhancing the stability of the contact point and preventing the pipe from loosening or falling off during use.

[0030] A threaded connector 13 is fixedly connected to the outer periphery of the through groove on the upper surface of the housing 1. A sealing ring 14 is provided at the bottom of the outer surface of the threaded connector 13. The threaded connector 13 can be threadedly connected to an external device. The sealing ring 14 can improve the tightness of the connection between the external pipe and the device and prevent water leakage.

[0031] A smooth connector 15 is fixedly connected to the lower surface of the housing 1 around the through groove. A raised ring 16 is provided on the outer surface of the smooth connector 15. The smooth connector 15 can be connected to an external pipe. The raised ring 16 increases the friction between the smooth connector 15 and the external pipe to prevent it from falling off on its own.

[0032] Working steps: First, the threaded connector 13 can be threaded to the external device, and the smooth connector 15 can be connected to the external pipe. The convex ring 16 increases the friction between the smooth connector 15 and the external pipe. Next, the fixed ring 9 is fixedly connected to the housing 1 to prevent the retaining ring 11 from being lost. Then, the retaining ring 11 moves relative to the surface of the threaded rod 10. Then, the limit nut 12 is tightened to limit and fix the position of the retaining ring 11, so that the retaining ring 11 fits tightly against the connection part between the external pipe and the device. The device is then processed. Next, the water flow impacts the first sealing plate 4. At the same time, the push rod 5 pushes the second sealing plate 6. Both move away from the sealing plate 7 simultaneously, thereby realizing the automatic opening of the drainage channel. Finally, under the push of the spring force 3, the first sealing plate 4 and the second sealing plate 6 automatically reset and fit tightly against the sealing plate 7, effectively preventing sewage backflow. At the same time, a water storage area is formed inside the housing 1, which plays a water seal role.
