The net basket 21 has multiple protrusions 22 on its inner side and multiple drainage grooves 23 on its inner side. The upper end of the net basket 21 is rotatably connected to a handle 24 via a pivot, and the lower end of the net basket 21 is fixedly connected to a flow guide hood 25.

[0019] Specifically, the mesh basket 21 can be detached from the drain body 1 via a movable connection, achieving the function of initially intercepting hair in the water flow; the inner protrusion 22 can change the water flow trajectory, guiding the water flow to form a vortex to gather and disperse hair; the drainage groove 23 allows water to smoothly penetrate downwards, while preventing hair from flowing directly out with the water flow; the handle 24 can rotate around the pivot, making it easy for users to hold and remove the mesh basket 21 and the connected guide cover 25, facilitating maintenance or replacement of parts; the guide cover 25 is fixed to the mesh basket 21, used to receive the water and hair flowing down from the mesh basket 21, and provides an installation carrier for subsequent crushing and filtering components, while guiding the water flow to be discharged into the sewer pipe.

[0021] Specifically, the filter screen 26 is fixed inside the guide shroud 25 to intercept shredded hair fragments and prevent insufficiently shredded impurities from entering the sewer. The toothed ring 27 is fixed to the upper end of the filter screen 26, and its inner toothed structure can cooperate with the turbine impeller 28 to form a shearing action to shred the hair. The turbine impeller 28 is rotatably connected to the filter screen 26 and can rotate at high speed around its own axis under the impact of water flow. The outer guide groove can enhance the impact force of water flow on the impeller and improve the rotation efficiency. The auger 29 rotates synchronously with the turbine impeller 28 through a rotating shaft, which can spirally transport the clumps of hair gathered in the basket 21 to the area of ​​the toothed ring 27. The conveying shell 210 is fixed to the lower end of the basket 21, which wraps around the auger 29, limits the hair conveying path, prevents hair from scattering during the conveying process, and provides rotational support for the auger 29.

[0022] In this embodiment, the cleaning mechanism 3 includes a first rotating shaft 31 rotatably connected to the filter screen 26. The upper end of the first rotating shaft 31 is fixedly connected to the turbine impeller 28. The lower end of the first rotating shaft 31 is fixedly connected to a slider 32. A slide cylinder 33 is slidably connected to the outside of the slider 32. A mounting plate 34 is fixedly connected to the lower end of the slide cylinder 33. Two symmetrical scrapers 35 are fixedly connected to the outside of the mounting plate 34. A slide rod 36 is fixedly connected to the outside of the slide cylinder 33.

[0023] Specifically, the upper end of the first rotating shaft 31 is fixed to the turbine impeller 28 and can rotate synchronously with the turbine impeller 28, transmitting rotational power to the downstream component of the cleaning mechanism 3; the slider 32 is fixed to the lower end of the first rotating shaft 31, and its outer side slides in cooperation with the inner side of the slide cylinder 33, so that the slide cylinder 33 can move up and down relative to the first rotating shaft 31, and rotate synchronously with the first rotating shaft 31; the slide cylinder 33, as a power transmission carrier, can drive the lower mounting plate 34 to rotate and move up and down synchronously; the mounting plate 34 is used to fix two symmetrical scrapers 35, ensuring the installation stability and force balance of the scrapers 35; the outer side of the scraper 35 is in contact with the inner wall of the guide shroud 25, and can scrape the hair debris and dirt attached to the inner wall during rotation and up and down movement to prevent blockage; the slide rod 36 is fixed to the outer side of the slide cylinder 33 and is used to cooperate with the annular slide groove 38 to provide trajectory guidance for the up and down movement of the slide cylinder 33.

[0024] In this embodiment, a sleeve 37 is rotatably connected to the outer side of the first rotating shaft 31. The upper end of the sleeve 37 is fixedly connected to the filter screen 26. An annular groove 38 is provided around the inner side of the sleeve 37. The inner side of the annular groove 38 is slidably connected to the slide rod 36.

[0025] Specifically, the upper end of the sleeve 37 is fixed to the filter screen 26, forming a rotational support for the first rotating shaft 31 and preventing the first rotating shaft 31 from shaking during rotation; the inner annular groove 38 has a spiral or wave-shaped trajectory, which slides in cooperation with the slide rod 36. When the slide cylinder 33 rotates with the first rotating shaft 31, the slide rod 36 moves along the trajectory of the annular groove 38, thereby converting the rotational motion into the up-and-down movement of the slide cylinder 33 along the axial direction of the sleeve 37, providing power guidance for the compound motion of the scraper 35.

[0026] In this embodiment, a spring 39 is provided on the outer side of the first rotating shaft 31. One end of the spring 39 is fixedly connected to the first rotating shaft 31, and the other end of the spring 39 is fixedly connected to the slide cylinder 33.

[0027] Specifically, the spring 39 is sleeved on the outside of the first rotating shaft 31, and its two ends are fixed to the first rotating shaft 31 and the slide cylinder 33 respectively, forming an elastic support structure. When the slide cylinder 33 moves downward along the first rotating shaft 31, the spring 39 is stretched to generate a restoring elastic force. When the slide cylinder 33 moves upward, the spring 39 releases the elastic force to assist in the restoring, ensuring the smooth movement of the slide cylinder 33 along the trajectory of the annular slide groove 38, avoiding the slide rod 36 from getting stuck in the annular slide groove 38, and at the same time enhancing the contact pressure between the scraper 35 and the inner wall of the guide shroud 25, thus improving the scraping effect.

[0028] In this embodiment, the cleaning mechanism 3 also includes two electric telescopic rods 310 installed inside the flow guide 25. The output shafts of the two electric telescopic rods 310 are fixedly connected to baffles 311. A sensor is provided on the inner side of the baffles 311. An annular rotating shaft 312 is rotatably connected to the outer side of the baffles 311 through a sliding sleeve. The outer side of the annular rotating shaft 312 is fixedly connected to the flow guide 25.

[0029] Specifically, two electric telescopic rods 310 are symmetrically installed inside the flow guide shroud 25, serving as the power source for the opening and closing of the baffle 311. The output shaft extends and retracts, driving the baffle 311 to rotate. When closed, the baffle 311 blocks the lower outlet of the flow guide shroud 25, preventing sewer odors and pests from entering. When open, it provides a channel for water to flow out. An inner sensor detects the presence of water flow, thereby controlling the electric telescopic rods 310 to start and automatically open and close the baffle 311. An annular rotating shaft 312 is fixed inside the flow guide shroud 25 and is rotatably connected to the baffle 311 via a sliding sleeve, providing a rotation fulcrum for the opening and closing of the baffle 311, reducing frictional resistance during rotation, and ensuring stable opening and closing.

[0030] Working principle: When the bathroom is draining water, the sensor inside the baffle 311 receives a signal and activates two electric telescopic rods 310. The output shaft drives the baffle 311 to rotate downwards along the annular shaft 312 to open. At the same time, the water flow carries hair into the basket 21. Under the guidance of multiple protrusions 22, the water flow forms a vortex, and the hair moves with the vortex. Subsequently, the water flow impacts the turbine impeller 28, causing it to rotate at high speed. The turbine impeller 28 drives the auger 29 to rotate through the shaft, causing the clumps of hair to enter the auger 29. Then, the hair is thrown towards the toothed ring 27 through the conveyor housing 210. Through the shearing action of the turbine impeller 28 and the toothed ring 27, the hair is pulverized into fragments. The water flow carries the fragments through the filter screen 26 and is discharged into the sewer pipe through the guide shroud 25. Meanwhile, the turbine impeller 28 drives the first rotating shaft 31 to rotate, and the first rotating shaft 31 drives the slide cylinder 33 to rotate. The slide cylinder 33 moves along the trajectory of the annular slide groove 38 via the slide rod 36, thereby causing the slide cylinder 33 to move up and down along the sleeve 37. When the slide cylinder 33 moves, its inner slide groove slides along the outer side of the slider 32. The slide cylinder 33 drives the mounting plate 34, and the mounting plate 34 further drives the scraper 35, so that the scraper 35 moves up and down while rotating. When the slide cylinder 33 moves downward, it will tighten the spring 39. When the slide cylinder 33 moves upward, the spring 39 returns to its original position, thereby scraping the inner wall of the guide shroud 25 through the scraper 35 to prevent the pipe from being blocked. After drainage is completed, the sensor inside the baffle 311 receives the signal and restarts the two electric telescopic rods 310; its output shaft drives the baffle 311 to rotate upward along the annular shaft 312 to close, so as to block the spread of sewer odor and prevent pests from entering; if parts need to be replaced, the user can take out the whole device through the handle 24 and then replace the parts.
