[0033] like Figure 3 As shown, the driving assembly includes a motor base 27, a motor 28, a gear 29 and a ring gear 30. The motor base 27 is fixed on the inner wall of the device housing 2 corresponding to the outer cavity 14, and the motor 28 is fixed on the motor base 27.

When the filter 19 rotates, the fixed scraper 2 18 can be used to scrape the surface of the filter 19 to ensure the smooth flow of the filter 19, thereby achieving the purpose of preventing blockage and drainage. In addition, it should be noted that the oblique support rod 15 cannot affect the rotation of the scraper 17. The oblique support rod 15 and the middle support rod 16 can be installed reasonably and adaptably.

[0036] The middle support rod 21 is also connected and fixed to the filter screen 19 through multiple oblique support rods 20 distributed circumferentially, which improves the reliability of relative fixation of the filter screen 19 and the middle support rod 21. The side support rod 1 23 is arranged perpendicular to the middle support rod 21. The transmission ball 24 is a spherical structure. The transmission ball 24 is connected to the arc groove 5 for anti-slip sliding. As for the shape of the arc groove 5, as long as the filter screen 19 moves along the inner cylinder 11, the side support rod 2 25 moves along the arc groove 5 and the filter screen 19 can rotate, no specific limitation is made.

[0037] The elastic component includes a rotating body 22, a side support rod 25 and an elastic telescopic rod 26.

[0038] like Figure 1 and 4As shown, as a preferred embodiment of the present invention, the sewage discharge and sedimentation component includes an impurity port 12, a spiral plate 3, a sedimentation pipe 8, a sedimentation cylinder 9 and a cleaning port 10, and the outer cavity 14 is close to the outer cavity 2 14. The end of the outer cavity 14 is provided with an impurity port 12 at the bottom of the inner cylinder 11, and the impurity port 12 is connected with the outer cavity 14, and when the filter screen 19 is abutted against the scraping component, the impurity port 12 is connected with the space on one side of the filter screen 19 close to the water inlet pipe 1, ensuring that the filter screen 19 can completely block the dirt and settle the dirt through the impurity port 12; the outer cavity 14 is in the outer wall of the inner cylinder 11 A spiral plate 3 is also fixed on it, and the outer ring of the spiral plate 3 is rotatably connected to the inner wall of the device shell 2. When the spiral plate 3 rotates with the inner cylinder 11, the spiral plate 3 is used to push the water in the outer cavity 4 to move away from the impurity port 12; the end of the outer cavity 14 away from the outer cavity 2 14 is also provided with a sedimentation pipe 8 at the bottom of the device shell 2, and the sedimentation pipe 8 is connected with the outer cavity 14.

A one-way valve (not shown) is also provided at the connection between the water pipe 7 and the water outlet pipe 6. The one-way valve is used to allow the water in the water pipe 7 to flow into the inner cavity of the water outlet pipe 6 and to cut off the reverse direction; the water pipe A dirt-blocking net 31 is also installed at the connection between the spiral plate 3 and the outer cavity 4, through which dirt can be blocked. A connecting rod 33 is also fixed to the end of the spiral plate 3 close to the water outlet pipe 6, and a scraper 32 is fixed to the end of the connecting rod 33 away from the spiral plate 3, which is in contact with the surface of the dirt-blocking net 31. When the spiral plate 3 rotates, the scraper 32 rotates accordingly, and the scraper 32 can be used to scrape the dirt on the surface of the dirt-blocking net 31, assisting the sedimentation to the sedimentation pipe 8 and the sedimentation cylinder 9, and ensuring the drainage of the water guide pipe 7. In addition, the one-way valve can improve the reliability of drainage, avoid the water in the water outlet pipe 6 from flowing in the direction of the body, and has high reliability.

[0040] In the embodiment of the present invention, no matter how the filter screen 19 moves, the impurity port 12 can discharge the dirt on the side of the filter screen 19 close to the water inlet pipe 1, with high reliability. By limiting the water transport of the spiral plate 3, the discharge and sedimentation of dirt can be accelerated. The superimposed arrangement of the water guide pipe 7, the dirt screening net 31, the scraper three 32 and the connecting rod 33 ensures the working effect of the spiral plate 3, thereby improving the overall effect of dirt sedimentation.

[0041] The above embodiment of the present invention provides a residential anti-blocking drainage device. When in use, when the water flow pressure in the inner cylinder 11 is normal, the inner cylinder 11 is driven to rotate by the driving component (the gear 29 can be driven to rotate by the motor 28, so that the gear 29 drives the gear ring 30 and the inner cylinder 11 to form an integral rotation, which is stable and reliable).
