A downcomer water accumulation inlet 12 communicating with the drain pipe 11 is fixedly connected to the back of the drain pipe 11. And the drain pipe 11 and the downcomer water accumulation inlet 12 form a tee structure.

[0041] An upper-stage filter screen 9 and a lower-stage filter screen 10 which are in damping sliding connection with the inner wall of the adjustable pipe sleeve 2 are arranged in the adjustable pipe sleeve 2 from top to bottom. Blocking rings capable of receiving the filter screens are arranged at the bottoms of the inner wall of the adjustable pipe sleeve 2 where the upper-stage filter screen 9 and the lower-stage filter screen 10 are located. Anti-odor check valves 13 are arranged inside both the drain pipe 11 and the downcomer water accumulation inlet 12.

[0042] According to the above structure, when the water seal liquid level height inside the first annular water seal 5 is insufficient, the water level sensor 7 sends an electrical signal to the alarm 8, causing the alarm 8 to issue an alarm, reminding relevant personnel to pay attention to the insufficient water seal liquid level, so that relevant personnel can timely add water to the interiors of the first annular water seal 5 and the second annular water seal 6, so that the liquid level of the water seal can always be maintained at a high level, ensuring the effect of the water seal.

[0043] And the drain pipe 11 and the downcomer water accumulation inlet 12 form a tee structure, and accumulated water at the bottom of the downcomer can be discharged through the downcomer water accumulation inlet 12 in the tee structure, effectively reducing the probability of downcomer water accumulation.

[0044] And a first-stage filter screen 9 and a second-stage filter screen 10 for filtering sundries, which are assembled in a damping sliding manner, are installed, facilitating the opening of the filter screen to clean the sundries inside the filter screen and the floor drain water seal box 1;

[0045] Meanwhile, the backflow of the discharged sewage is effectively avoided through the action of the anti-odor check valves 13 respectively installed inside the drain pipe 11 and the sunken floor water inlet 12.

[0046] Refer to the appendix Figure 2 - 10 , a placement groove 14 is opened at the middle position on the top of the stainless steel metal floor drain cover plate 3, a placement tray 15 is placed inside the placement groove 14, a through groove 17 communicating with the placement groove 14 is opened at the position corresponding to the placement tray 15 at the bottom of the stainless steel metal floor drain cover plate 3, the diameter of the through groove 17 is smaller than the diameter of the placement tray 15, a connecting rod 16 is rotatably arranged at the bottom of the placement tray 15, a damping sliding connecting rod 22 is fixedly arranged at the bottom of the placement tray 15, the bottom of the damping sliding connecting rod 22 extends into the inside of the connecting rod 16, and the outer wall of the damping sliding connecting rod 22 is damping slidably connected with a damping sliding sleeve 23, a water storage pipe 24 is fixedly arranged at the bottom of the damping sliding sleeve 23, and the density of the water storage pipe 24 is less than that of water, the damping sliding sleeve 23 is located inside the water storage pipe 24, water inlets 28 are symmetrically opened at the top of both sides of the connecting rod 16, and the water inlets 28 are located above the water storage pipe 24, the top of the water storage pipe 24 is of an open structure, a second ball 26 is fixedly arranged on one side of the water storage pipe 24, a sliding groove 25 is opened at the position corresponding to the second ball 26 on the inner wall of the connecting rod 16, the sliding groove 25 is slidably connected with the second ball 26, a spiral sliding groove 27 communicating with the sliding groove 25 is opened at the bottom of the inner wall of the connecting rod 16, and the spiral sliding groove 27 is adapted to the second ball 26;

[0047] Four cleaning rods 18 are equally spaced and hinged at the bottom of the outside of the connecting rod 16, the cleaning rods 18 are in a sword-shaped structure with thin sides and thick middle, a positioning column 19 is fixedly arranged at one end of the cleaning rod 18 away from the connecting rod 16, a first ball 20 is rotatably arranged at one end of the top of the positioning column 19, a limiting ring 29 is fixedly arranged above the positioning column 19 on the inner wall of the adjustable pipe sleeve 2, an annular sliding groove 33 is opened at the position corresponding to the first ball 20 at the bottom of the limiting ring 29, one side of the first ball 20 is located inside the annular sliding groove 33 and is slidably connected with the inner wall of the annular sliding groove 33, through grooves 30 penetrating through the inside of the limiting ring 29 are equally spaced and opened at the bottom of the limiting ring 29, the diameter of the through groove 30 is larger than the diameter of the positioning column 19, a hinge piece 38 is fixedly arranged at one end of the cleaning rod 18, and a hinge shaft 39 is fixedly arranged at the position corresponding to the hinge piece 38 at the bottom inside the connecting rod 16, and a torsion spring 40 is arranged between the hinge shaft 39 and the hinge piece 38.

[0048] According to the above structure, when there are people with long hair among the users of the house, the fallen long hair may flow into the interior of the adjustable sleeve 2 along with the water flow and land on the primary filter screen 9. At this time, the long hair may cause the primary filter screen 9 to be blocked, which is not conducive to drainage. When the primary filter screen 9 is blocked by long hair, the liquid level at the top of the primary filter screen 9 inside the adjustable sleeve 2 gradually rises, so that the liquid level gradually submerges the water inlet 28 on the connecting rod 16, and the water flow gradually flows into the interior of the water storage pipe 24 through the water inlet 28. As the amount of water inside the water storage pipe 24 increases, the gravity exerted on the water storage pipe 24 gradually becomes greater than the frictional force between the damping sliding connecting rod 22 and the damping sliding sleeve 23, so that the water storage pipe 24 drives the damping sliding sleeve 23 to slide downward on the outer wall of the damping sliding connecting rod 22. During the downward sliding process of the water storage pipe 24, the water storage pipe 24 drives the second ball 26 to enter the interior of the spiral sliding groove 27 from the interior of the sliding groove 25 and continue to slide inside the spiral sliding groove 27. When the second ball 26 slides along the trend of the spiral sliding groove 27, the connecting rod 16 rotates, so that the connecting rod 16 drives the cleaning rod 18 and the positioning column 19 to rotate. During the rotation process of the cleaning rod 18, a large amount of long hair winds around the cleaning rod 18. During the rotation process of the positioning column 19, the positioning column 19 drives the first ball 20 to slide inside the annular sliding groove 33. When the cleaning rod 18 drives the positioning column 19 to rotate to the moving position, the position of the positioning column 19 corresponds to the through groove 30. At this time, the limiting ring 29 no longer limits the position of the top of the positioning column 19. Due to the elastic force of the coil spring 40, one end of the cleaning rod 18 drives the positioning column 19 to rotate towards the direction close to the top of the connecting rod 16. At this time, the end of the cleaning rod 18 far from the hinge shaft 39 gathers towards the top of the connecting rod 16. During the gathering process, the cleaning rod 18 picks up the hair located between the primary filter screen 9 and the top of the cleaning rod 18, and clamps and positions the hair through the cooperation of the cleaning rod 18 and the connecting rod 16, so as to effectively dredge the long hair blocked on the primary filter screen 9 and ensure the smoothness of the primary filter screen 9. When the clamping is completed, at this time, since the limiting ring 29 no longer positions the cleaning rod 18, due to the buoyancy of the water, the top end of the connecting rod 16 drives the placement plate 15 to gradually float upward, so that the top of the connecting rod 16 protrudes from the surface of the stainless steel metal floor drain cover 3, so that the house user can quickly discover the situation that the primary filter screen 9 is blocked, so that the house user can timely clean the long hair on the primary filter screen 9, ensure the smoothness of the primary filter screen 9, and reduce the probability of the primary filter screen 9 being blocked for a long time;

[0049] When the placement plate 15 protruding from the surface of the stainless steel metal floor drain cover 3 is found, the placement plate 15 can be pulled out upward, so that the placement plate 15 drives the connecting rod 16 and the cleaning rod 18 to gradually pass through the through groove 17 and move to the outside of the adjustable sleeve 2, which is convenient for thoroughly cleaning the long hair clamped between the connecting rod 16 and the cleaning rod 18.

[0050] Refer to the attached Figure 9 、 11 11

[0051] According to the above structure, when the connecting rod 16 rotates, the placement plate 15 is positioned through the cooperation of the limiting block 32 and the limiting groove 35, so as to position the damping sliding connecting rod 22 fixedly connected to the placement plate 15. Furthermore, the damping sliding sleeve 23 is positioned through the slider 37 on the outer wall of the damping sliding connecting rod 22 and the sliding groove 36 on the inner wall of the damping sliding sleeve 23. Therefore, the water storage pipe 24 fixedly connected to the damping sliding sleeve 23 is positioned to prevent the water storage pipe 24 from rotating with the connecting rod 16 when the connecting rod 16 rotates.

[0052] Refer to the attached Figure 5 and 9 9

[0053] According to the above structure, when the top of the connecting rod 16 floats upward, the top of the connecting rod 16 drives the fluorescent ring 34 to protrude from the surface of the stainless steel metal floor drain cover 3. At this time, the fluorescent ring 34 emits fluorescence, so that relevant personnel can more quickly discover the blockage of the primary filter 9 in dim light, enabling the house user to clean the long hair on the primary filter 9 in time, ensuring the smoothness of the primary filter 9, and reducing the probability of the primary filter 9 being blocked for a long time.

[0054] Refer to the attached Figure 4 and 5 5

[0055] According to the above structure, when the limiting ring 29 no longer limits the positioning post 19 and the cleaning rod 18, it is more convenient for the connecting rod 16 to float up.

[0056] Refer to the attached Figure 6 Figure 6

[0057] According to the above structure, the water on the limiting ring 29 can be discharged through the water leakage grooves 31.

[0058] The working principle of the present invention is as follows:

[0059] When the drainage device is in use, sufficient water is injected into the first annular water seal 5 inside the floor drain water seal box 1 as the water seal, so that the water surface submerges the detection end of the water level sensor 7. When the liquid level of the water seal drops to the bottom of the detection end of the water level sensor 7, the water level sensor 7 detects that the liquid level of the water seal is relatively low, and the water level sensor 7 sends an electrical signal to the alarm 8, causing the alarm 8 to emit an alarm, thereby reminding the user that the liquid level of the water seal is relatively low and prompting the user to add water to the inside of the first annular water seal 5 and the second annular water seal 6 in time;

[0060] When draining water through this device, the surface water accumulation in areas such as the bathroom or kitchen drains into the adjustable pipe sleeve 2 of the floor drain cover plate. The drainage passes through the primary filter screen 9 and the secondary filter screen 10 with different thicknesses for filtration to separate solid garbage. The two-stage filter screens are assembled and installed, which is convenient for opening and cleaning the garbage. At the same time, the filter screens can prevent pests and the like from invading. The drainage passes through the filter screen and reaches the bottom of the floor drain water seal box 1. When the liquid level inside the floor drain water seal box 1 reaches a certain height, the liquid level of the water flow submerges the first annular water seal 5 and the second annular water seal 6, and is discharged to the riser through the anti-odor check valve 13;

[0061] When there are people with long hair among the users of the house, the fallen long hair may flow into the interior of the adjustable sleeve 2 along with the water flow and land on the primary filter screen 9. At this time, the long hair may cause the primary filter screen 9 to be blocked, which is not conducive to drainage. When the primary filter screen 9 is blocked by long hair, the liquid level at the top of the primary filter screen 9 inside the adjustable sleeve 2 gradually rises, so that the liquid level gradually submerges the water inlet 28 on the connecting rod 16, and the water flow gradually flows into the interior of the water storage pipe 24 through the water inlet 28. As the amount of water inside the water storage pipe 24 increases, the gravity exerted on the water storage pipe 24 gradually becomes greater than the frictional force between the damping sliding connecting rod 22 and the damping sliding sleeve 23, so that the water storage pipe 24 drives the damping sliding sleeve 23 to slide downward on the outer wall of the damping sliding connecting rod 22. During the downward sliding process of the water storage pipe 24, the water storage pipe 24 drives the second ball 26 to enter the interior of the spiral sliding groove 27 from the interior of the sliding groove 25 and continue to slide inside the spiral sliding groove 27. When the second ball 26 slides along the trend of the spiral sliding groove 27, the connecting rod 16 rotates, so that the connecting rod 16 drives the cleaning rod 18 and the positioning column 19 to rotate. During the rotation process of the positioning column 19, the positioning column 19 drives the first ball 20 to slide inside the annular sliding groove 33. When the cleaning rod 18 drives the positioning column 19 to rotate to the moving position, the position of the positioning column 19 corresponds to the through groove 30. At this time, the limiting ring 29 no longer limits the position of the top of the positioning column 19. Due to the elastic force of the coil spring 40, one end of the cleaning rod 18 drives the positioning column 19 to rotate in the direction close to the top of the connecting rod 16. At this time, the end of the cleaning rod 18 away from the hinge shaft 39 gathers towards the top of the connecting rod 16. During the gathering process, the cleaning rod 18 picks up the hair located between the primary filter screen 9 and the top of the cleaning rod 18, and clamps and positions the hair through the cooperation of the cleaning rod 18 and the connecting rod 16. When the clamping is completed, at this time, since the limiting ring 29 no longer positions the cleaning rod 18, due to the buoyancy of the water, the top end of the connecting rod 16 drives the placement tray 15 to gradually float upward, so that the top of the connecting rod 16 drives the fluorescent ring 34 to protrude from the surface of the stainless steel metal floor drain cover 3, so that relevant personnel can quickly discover the situation that the primary filter screen 9 is blocked;

[0062] After the placement tray 15 protruding from the surface of the stainless steel metal floor drain cover 3 is found, the placement tray 15 can be pulled out upward, so that the placement tray 15 drives the connecting rod 16 and the cleaning rod 18 to gradually pass through the through groove 17 and move to the outside of the adjustable sleeve 2, facilitating a thorough cleaning of the long hair clamped between the connecting rod 16 and the cleaning rod 18.

[0063] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented by conventional means in the art without special instructions and limitations.
