The slot filter cartridge cooperates with the bottom plate 10 to form a groove-shaped filtering structure, which can temporarily store impurities such as hair that have been filtered and intercepted, and prevent the intercepted impurities from being washed away from the surface of the filter screen surface 7 after contacting the water body, thereby preventing the filter screen surface 7 from increasing the difficulty of intercepting impurities such as hair; the slot filter cartridge includes a bottom plate 10 with a through hole 11, a filter screen surface 7 and a fixing ring 8, and the filter screen surface 7 is surrounded by a circle along the side wall of the bottom plate 10. The filter surface 7 is a table-shaped columnar body, and a plurality of filter holes are formed on the surface of the filter surface 7. The filter surface 7 is a stainless steel filter. The filter surface 7 intercepts impurities such as hair through the filter holes on its inner wall. The diameter of the bottom plate 10 is smaller than the inner diameter of the floor drain core 6, so that a gap can be formed between the filter surface 7 and the floor drain core 6, which is convenient for the filtered water to fall inside the floor drain core 6. The fixing ring 8 cooperates with the bottom plate 10 to fix the filter surface 7, so that the filter surface 7 surrounds the bottom plate 10 to form a cylindrical filtering surface, and the filter surface 7 surrounds the top of the bottom plate 10. On the side wall, a floor drain core 6 is coaxially welded to the bottom of the floor drain body 1 through a water discharge joint 5, and a handle structure is fixed at the top middle of the bottom plate 10. The handle structure facilitates the rotation of the fixing ring 8 to separate the filter surface 7 from the floor drain body 1, so as to facilitate the cleaning of impurities such as hair intercepted on the filter surface 7. The handle structure includes a fixed pipe 12, and a telescopic rod 13 is threadedly connected to the inner wall of the fixed pipe 12. The length of the telescopic rod 13 does not exceed the length of the fixed pipe 12, so as to avoid the minimum value of the sum of the lengths of the telescopic rod 13 and the fixed pipe 12 being greater than the height of the filter surface 7.
[0020] Preferably, Figure 1 As shown, the floor drain body 1 is a rectangular block made of stainless steel, the thickness of the floor drain body 1 is 5 mm, and the floor drain body 1 is embedded and fixed with the ground concrete, so that the floor drain body 1 can be fixedly installed.
[0021] Preferably, Figure 1 As shown, a thread groove 4 is formed on the inner wall of the filter port 3, and a thread line adapted to the thread groove 4 is formed on the surface of the fixing ring 8. The fixing ring 8 is threadedly connected to the inner wall of the filter port 3 to form a detachable connection structure, which is convenient for installing and removing the fixing ring 8.
[0022] Preferably, Figure 1As shown, a groove 2 co-centering with the filter port 3 is provided at the top of the floor drain body 1, and a limiting ring 9 is welded to the top of the fixing ring 8. The limiting ring 9 is tangent to the groove 2, and the thickness of the limiting ring 9 is less than the depth of the groove 2. The limiting ring 9 is tangent to the groove 2, and the groove 2 can support and limit the limiting ring 9, thereby reducing the load and wear risk of the threaded groove 4.

The handle 14 can improve the convenience of rotating the telescopic rod 13 .
[0024] Working principle: When in use, turn the handle 14 to retract the telescopic rod 13 into the fixed tube 12, so that the top surface of the handle 14 is not higher than the top surface of the floor drain body 1, and the filter surface 7 is surrounded by the side wall of the bottom plate 10 to form a hollow cylindrical surface or a truncated table surface. At the same time, the diameter of the bottom plate 10 is set to be smaller than the inner diameter of the floor drain core 6, so that a gap can be formed between the filter surface 7 and the floor drain core 6, so that the filtered water can fall inside the floor drain core 6. By setting a grooved filter cartridge as an interception structure for filtering hair in the floor drain, it can be more effective than the traditional flat filter. The hair that has been filtered multiple times is temporarily stored to prevent the intercepted hair and other impurities from drifting away from the filter surface 7 under the scouring of the water flow, thereby realizing centralized cleaning of the hair intercepted by the filter surface 7 and reducing the difficulty of intercepting the hair and other impurities by the filter surface 7. After intercepting the hair, the telescopic rod 13 can be extended out of the fixed tube 12 by rotating the handle 14 in the reverse direction. When it is further rotated, the fixing ring 8 can be pulled to rotate through the bottom plate 10 to separate the fixing ring 8 from the threaded groove 4, thereby taking out the filter surface 7 from the floor drain body 1 for centralized cleaning of the filter surface 7.
