Description

Technical Field

[0001] This application relates to the field of floor drains, and in particular to a high-performance concealed floor drain. Background Technology

[0002] Floor drains are an important appliance for removing water from the floor and serve as a crucial interface between the drainage pipe system and the indoor floor. As a vital component of the drainage system in a residence, their performance directly affects indoor air quality and is extremely important for controlling odors in the bathroom.

[0003] The invention patent with authorization announcement number CN106869293A discloses a floor drain, including a shell with an inlet and an outlet and an internal cavity. The shell has a filter cover at the inlet and a filter cup with its opening facing the inlet at the outlet. The filter cup has several drainage holes on its side wall and a water-sealing structure to prevent odor backflow. The water-sealing structure includes a floor drain base and a back pressure cup. The bottom of the floor drain base has a drain pipe with its inlet end face higher than the bottom of the floor drain base. The opening of the back pressure cup has several support feet. The back pressure cup is placed upside down at the bottom of the floor drain base and covers the drain pipe. The inlet end face of the drain pipe is lower than the bottom of the back pressure cup but higher than the opening end face of the back pressure cup. The filter cup is placed on the back pressure cup. The floor drain base is fitted onto the outer circumference of the shell.

[0004] When using a floor drain, the end face of the filter cover is flush with the ground. When users walk through the floor drain, impurities adhering to the soles of their shoes easily stick to the end face of the filter cover. When the filter cover filters impurities in the sewage, these impurities accumulate on the end face of the filter cover and block it. Sewage cannot easily pass through the filter cover and drain from the drain hole. Users need to clean the filter cover before and after each use, which reduces users' satisfaction with using the floor drain. Summary of the Invention

[0005] To address the problem of impurities accumulating on the filter cover and clogging its end face, this application provides a high-performance concealed floor drain.

[0006] This application provides a high-performance concealed floor drain, which adopts the following technical solution:

[0007] A high-performance concealed floor drain includes a housing and a connecting pipe. The ends of the housing and the connecting pipe are fixed. A drain hole for sewage discharge is provided on the connecting pipe. A water inlet groove is provided on the outer wall of the housing away from the connecting pipe. An abutment block is fixed on the inner wall of the water inlet groove near the connecting pipe. A hidden plate is connected to the housing. When the hidden plate is located in the water inlet groove, the outer wall of the hidden plate abuts against the end face of the abutment block to form a limit, and the end face of the hidden plate is flush with the end face of the housing. A water flow gap is left between the circumferential outer wall of the hidden plate and the inner wall of the water inlet groove. A filter groove is provided on the inner wall of the water inlet groove near the connecting pipe, and the filter groove is connected to the drain hole and the water inlet groove. A filter screen is connected to the circumferential inner wall of the filter groove. The filter screen is located on the side of the filter groove near the water inlet groove. Water on the ground passes through the water flow gap, the water inlet groove, the filter groove, and the filter screen in sequence and is discharged from the drain hole. A cleaning component is connected to the housing for cleaning impurities on the end face of the filter screen.

[0008] By adopting the above technical solution, the outer wall of the shell is embedded in the ground to form a fixed structure, and the end face of the shell is flush with the ground. The outer wall of the connecting pipe is fixed to the inner wall of the drainage pipe, thereby realizing the installation of a high-performance concealed floor drain. Water on the ground passes through the water flow gap, the inlet tank, the filter tank, and the filter screen in sequence and is discharged from the drain hole, realizing the drainage of water on the ground. The concealed plate is placed in the drain tank, and the end face of the concealed plate abuts against the end face of the abutment block to form a limit. The end face of the concealed plate is flush with the end face of the shell. The concealed plate is located above the filter screen and covers the filter screen, thus concealing the filter screen. Impurities on the ground are not easily adhered to the end face of the filter screen as the user walks, making the end face of the filter screen less likely to be blocked by impurities. At the same time, the cleaning component cleans the impurities on the end face of the filter screen, thereby reducing the number of times the user cleans the filter screen and improving the user's comfort in using the high-performance concealed floor drain.

[0009] Optionally, the filter screen includes a filter section, the outer wall of which is fixed against the inner wall of the water filter tank, and a guide surface is provided on the end face of the filter section facing the hidden plate. The inclination height of the guide surface increases as the distance to the axis of the connecting pipe decreases.

[0010] By adopting the above technical solution, the guide surface is inclined, which increases the filtration area of ​​the filter screen in the water filter tank. The inclination height of the guide surface increases as the distance to the axis of the connecting pipe decreases, making it less likely for impurities to accumulate on the guide surface and clog the filter screen, thereby improving the drainage stability of the high-performance concealed floor drain.

[0011] Optionally, the end of the connecting pipe away from the housing is rotatably connected to a cover plate for opening and closing the drain hole. The cover plate rotates towards or away from the connecting pipe. A power component is connected between the cover plate and the connecting pipe. The power component has the tendency to drive the cover plate to rotate towards the connecting pipe and close the drain hole.

[0012] By adopting the above technical solution, the power component drives the cover plate to rotate towards the connecting pipe and seals the drain hole, making it difficult for sewage or insects in the external drainage pipe to enter the inlet tank through the drain hole, thereby improving the sealing performance of the high-performance concealed floor drain; when the ground water passes through the water flow gap, inlet tank, filter tank, filter screen and enters the drain hole in sequence, the water in the drain hole impacts the cover plate and drives the cover plate to rotate away from the connecting pipe, so that the sealing effect of the drain hole disappears, thereby realizing the discharge of ground sewage.

[0013] Optionally, the cleaning assembly includes a cleaning brush and a driving component. The cleaning brush is slidably connected to one end face of the filter section. The cleaning brush moves along a guide surface toward or away from the connecting pipe. The driving component is used to receive power from the cover plate and drive the cleaning brush to slide.

[0014] By adopting the above technical solution, when the water in the drain hole impacts the cover plate and drives the cover plate to rotate away from the connecting pipe, the driving component receives the power of the cover plate and drives the cleaning brush to move closer to or away from the connecting pipe along the guide surface, thereby realizing automatic cleaning of the filter screen. Users do not need to clean the end face of the filter screen before and after use, thus improving the user's comfort when using the high-performance concealed floor drain.

[0015] Optionally, a collection trough is provided on the inner wall of the filter tank facing the hidden plate. The collection trough is located on the side of the guide surface near the connecting pipe. When the cleaning brush slides along the guide surface towards the collection trough, the cleaning brush drives the impurities on the guide surface into the collection trough.

[0016] By adopting the above technical solution, the cleaning brush drives the impurities on the guide surface into the collection tank, thereby collecting the impurities and making it difficult for them to flow in the water filter tank, thus improving the cleaning efficiency of the high-performance concealed floor drain for users.

[0017] Optionally, a collection plate is slidably connected to the inner wall of the collection tank. The sliding direction of the collection plate is towards or away from the hidden plate. The end face of the collection plate facing the hidden plate is used to collect impurities in the sewage.

[0018] By adopting the above technical solution, when the user needs to clean the high-performance concealed floor drain, the collection plate is driven to slide away from the shell, thereby separating the collection plate from the shell and making it convenient for the user to clean the collection plate.

[0019] Optionally, the collecting plate includes a collecting part and an abutting part. The ends of the collecting part and the abutting part are fixed. Both the collecting part and the abutting part are strip plates. The length direction of the collecting part and the length direction of the abutting part are perpendicular to each other. When the collecting plate slides towards the direction of the hidden plate, the end face of the collecting part is flush with the bottom surface of the guide surface, and the end face of the abutting part away from the collecting part abuts against the end face of the hidden plate.

[0020] By adopting the above technical solution, the end face of the collection section is flush with the bottom surface of the guide surface. The cleaning brush drives the impurities on the guide surface into the end face of the collection section, thereby cleaning the garbage on the end face of the filter screen. The end face of the contact section abuts against the end face of the hidden plate, providing support for the hidden plate and making it less likely to shift within the drainage groove. This improves the connection stability between the hidden plate and the housing. When the user needs to clean the garbage on the end face of the collection section, the user holds the outer wall of the contact section and drives the collection section to slide away from the connecting pipe, thereby separating the collection plate from the housing. This facilitates the user's cleaning of the high-performance concealed floor drain.

[0021] Optionally, the end face of the collecting part is provided with a plurality of collecting holes, the collecting holes penetrate the outer wall of the collecting part and are connected to the collecting groove. The inner wall of the collecting groove near the axis of the connecting pipe is provided with a through groove, the through groove is connected to the collecting groove and the filtering groove. When the cleaning brush drives water into the end face of the collecting part, the water passes through the collecting holes, the collecting groove, the through groove and the filtering groove in sequence and is discharged from the drain hole.

[0022] By adopting the above technical solution, water on the end face of the collection section passes through the collection tank, the through tank, and the filter tank in sequence along the collection hole and is discharged from the drain hole, so that water is not easy to accumulate on the end face of the collection section, thereby achieving the filtration of water and impurities on the end face of the collection section.

[0023] Optionally, a warning component is connected to the housing. The warning component is used to receive the power of the collecting plate and drive the hidden plate to slide. When the collecting plate slides towards the connecting pipe, the warning component receives the power of the collecting plate and drives the hidden plate to slide away from the housing, and the end face of the hidden plate protrudes from the end face of the housing.

[0024] By adopting the above technical solution, the cleaning brush drives impurities from the filter screen end face into the collection section end face. Water flows sequentially through the collection groove, through groove, and filter groove along the collection hole and is discharged from the drain hole. Impurities accumulate on the collection section end face, and gravity drives the collection plate to slide away from the concealed plate. The warning component receives the power from the collection plate and drives the concealed plate to slide away from the housing, causing the concealed plate end face to protrude from the housing end face, thus alerting the user to clean the collection plate. This eliminates the need for the user to frequently open the collection plate to inspect the housing cavity, thereby improving the user's comfort in using the high-performance concealed floor drain.

[0025] Optionally, the power component is a power torsion spring, with both ends of the power torsion spring correspondingly abutting against the outer wall of the connecting pipe and the outer wall of the cover plate. The power torsion spring has the elastic force to drive the cover plate to slide closer to the connecting pipe and close the drain hole.

[0026] By adopting the above technical solution, the power torsion spring drives the cover plate to rotate towards the connecting pipe and seals the drain hole, making it difficult for sewage or insects in the external drainage pipe to enter the inlet tank through the drain hole, thereby improving the sealing performance of the high-performance concealed floor drain; when the ground water enters the drain hole through the water flow gap, the inlet tank and the filter tank in sequence, the water in the drain hole impacts the cover plate and drives the cover plate to rotate away from the connecting pipe, so that the sealing effect of the drain hole disappears and the sewage on the ground is discharged.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The hidden plate and cleaning component are designed to conceal the filter screen, preventing impurities on the ground from adhering to the filter screen end face as the user walks, thus preventing the filter screen end face from being clogged by impurities. At the same time, the cleaning component cleans the impurities on the filter screen end face, thereby reducing the number of times the user needs to clean the filter screen.

[0029] 2. The design of the power components and cover plate makes it difficult for sewage or insects in the external drainage pipe to enter the inlet tank through the drain hole, thereby improving the sealing performance of the high-performance concealed floor drain.

[0030] 3. The settings for the drive unit and cleaning brush enable automatic cleaning of the filter screen, eliminating the need for users to clean the filter screen end face before and after use. Attached Figure Description

[0068] Reference Figure 8 and Figure 9 The warning component 26 includes an elastic element 261, a gear set 262, a rack 1 263, a rack 264, and a rack 3 265. The gear set 262 includes a gear 1 2621, a gear 2622, and a gear 3 2623, which are sequentially and coaxially welded and fixed. The ends of the gears 1 2621 and 3 2623 that are far apart from each other are rotatably connected to the inner wall of the mounting cavity 25, and the rotation axis of the gear set 262 is perpendicular to the sliding direction of the collecting part 201.

[0069] Reference Figure 2 and Figure 3 A warning groove 31 is provided on the end face of the abutment block 3 facing the hidden plate 4. The depth direction of the warning groove 31 is parallel to the sliding direction of the collection part 201, and the warning groove 31 penetrates the abutment block 3 along the depth direction and connects to the mounting cavity 25. One end of the rack 263 passes through the warning groove 31 of one of the abutment blocks 3 and enters the mounting cavity 25.

[0070] Reference Figure 3 and Figure 9 One end of rack 263 meshes with gear 2621, and the other end of rack 263 is flush with the end face of abutment block 3, and the end face of rack 263 is used to abut the end face of concealed plate 4.

[0071] Reference Figure 2 and Figure 3 One end of the rack 3265 passes through the warning groove 31 of the abutment block 3 on the same side and enters the mounting cavity 25.

[0072] Reference Figure 3 and Figure 9 One end of rack 3 265 meshes with gear 3 2623, and the other end of rack 3 265 is flush with the end face of abutment block 3. One end of rack 3 265 is used to abut the end face of hidden plate 4.

[0073] Reference Figure 3 and Figure 9Rack 264 is slidably connected to the inner wall of the mounting cavity 25. The sliding axes of rack 1 263, rack 264, rack 3 265 and the collecting part 201 are parallel to each other, and rack 264 meshes with gear 2622.

[0074] Reference Figure 3 and Figure 9 A sealing plate is welded and fixed to the end of rack 264 facing the hidden plate 4. The outer wall of the sealing plate is slidably connected to the inner wall of the filter tank 22. The sliding direction of the sealing plate is towards or away from the hidden plate 4. The outer wall of the sealing plate abuts against the inner wall of the filter tank 22 and seals the mounting cavity 25. Rack 1 263 and rack 3 265 are located on the same side of the rotation axis of gear set 262, while rack 264 is located on the other side of the rotation axis of gear set 262.

[0075] Reference Figure 3 The elastic element 261 can be a compression spring or a torsion spring. In this embodiment, the elastic element 261 is a compression spring, which has a certain deformation capability. The two ends of the elastic element 261 in the direction of elastic force are welded and fixed to the end of the rack 264 and the inner wall of the mounting cavity 25. The elastic force of the elastic element 261 drives the rack 264 to slide towards the hidden plate 4.

[0076] Reference Figure 4 and Figure 8 A limiting block 27 is welded and fixed to the outer wall of the rack 264 facing the collection part 201. A limiting hole 2641 is opened on the outer wall of the rack 264 facing the filter screen 7. The limiting hole 2641 is located on the side of the limiting block 27 close to the hidden plate 4. A fixing block 28 is connected to the rack 264. The fixing block 28 is slidably connected to the inner wall of the limiting hole 2641. The sliding direction of the fixing block 28 is parallel to the axis of the limiting hole 2641.

[0077] Reference Figure 4 and Figure 8 An elastic element 29 is connected between the fixing block 28 and the inner wall of the limiting hole 2641. The elastic element 29 can be a compression spring or a torsion spring. In this embodiment, the elastic element 29 is a compression spring and has a certain deformation capability. The elastic element 29 forces the fixing block 28 to slide towards the filter screen 7. A limiting gap 281 is left between the fixing block 28 and the limiting block 27. When the outer wall of the collecting part 201 abuts against the end of the fixing block 28, the outer wall of the collecting part 201 forces the fixing block 28 to slide away from the filter screen 7. The bottom wall of the collecting part 201 abuts against the outer wall of the limiting block 27. At the same time, the outer wall of the collecting part 201 disengages from the end of the fixing block 28. The elastic element 29 forces the fixing block 28 to slide towards the filter screen 7. The outer wall of the fixing block 28 abuts against the top of the collecting part 201, so that the end of the collecting part 201 is limited within the limiting gap 281, realizing the connection between the collecting plate 20 and the rack 264.

[0078] Reference Figure 4 and Figure 9 When the elastic element 261 forces the rack 264 to slide closer to the hidden plate 4, the ends of rack 1 263 and rack 3 265 are flush with the end face of the abutment block 3, and the ends of rack 1 263 and rack 3 265 abut against the end face of the hidden plate 4. At the same time, the cleaning brush 81 drives the impurities on the end face of the filter screen 7 into the end face of the collection section 201. Water flows along the collection hole 203 through the through groove 24 and the filter groove 22 and is discharged from the drain hole 11. Impurities accumulate on the end face of the collection section 201, and the gravity of the impurities drives the collection plate 20 away from the hidden plate 4. The direction of the sliding motion causes rack 264 to slide away from the concealed plate 4. Gear 1 2621, gear 2622, and gear 3 2623 rotate, driving rack 1 263 and rack 3 265 to slide away from the connecting pipe 1. The concealed plate 4, which abuts against rack 1 263 and rack 3 265, slides away from the housing 2, causing the end face of the concealed plate 4 to protrude from the end face of the housing 2. This alerts the user to clean the collection plate 20, eliminating the need for the user to frequently check the inner cavity of the housing 2, and further improving the user's comfort in using the high-performance concealed floor drain.

[0079] The implementation principle of a high-performance concealed floor drain in this application embodiment is as follows: When the high-performance concealed floor drain is in use, the concealed plate 4 is located above the filter screen 7, and the concealed plate 4 covers the filter screen 7, thereby concealing the filter screen 7. Impurities on the ground are not easily adhered to the end face of the filter screen 7 as the user walks, so that the end face of the filter screen 7 is not easily blocked by impurities, thereby reducing the number of times the user cleans the filter screen 7.

[0080] During drainage, the water on the ground passes through the water flow gap 41, the water inlet trough 21, the water filter trough 22, and the sieve hole 73 in sequence and enters the drain hole 11. The water in the drain hole 11 impacts the cover plate 5 and drives the cover plate 5 to rotate away from the connecting pipe 1, so that the sealing effect of the drain hole 11 disappears, thereby realizing the discharge of sewage from the ground.

[0081] Simultaneously, slider 9 slides along slide groove 51 away from power component 6, driving slide rod 824 to slide along inner wall of connecting groove 14 away from connecting pipe 1, driving abutment rod 19 to slide along inner wall of limiting arc groove 15 towards cover plate 5, driving cleaning brush 81 to slide along end face of filter part 71 towards connecting pipe 1, and cleaning brush 81 bristles to slide into contact with end face of filter part 71, cleaning end face of filter part 71, realizing automatic cleaning of filter screen 7, eliminating the need for users to clean filter screen 7 regularly, thereby improving user comfort when using high-performance concealed floor drain.

[0082] When the bristles of the cleaning brush 81 drive the impurities on the end face of the filter screen 7 to enter the end face of the collection section 201 along the end face of the filter screen 7, water flows along the collection hole 203 through the through groove 24 and the filter groove 22 in sequence and is discharged from the drain hole 11. The impurities accumulate on the end face of the collection section 201. The gravity of the impurities drives the collection plate 20 to slide away from the hidden plate 4, which drives the rack 264 to slide away from the hidden plate 4. The gears 1 2621, 2622 and 3 2623 rotate and drive the racks 1 263 and 3 265 to slide away from the connecting pipe 1. The hidden plate 4, which abuts against the racks 1 263 and 3 265, slides away from the housing 2, so that the end face of the hidden plate 4 protrudes from the end face of the housing 2, thereby alerting the user to clean the collection plate 20. The user does not need to check the inner cavity of the housing 2 frequently, which further improves the user's comfort in using the high-performance concealed floor drain.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
