Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to a pre-embedded anti-seepage and anti-odor floor drain. Background Technology

[0002] Floor drains are crucial interfaces connecting indoor floors to drainage systems. As a vital component of residential drainage systems, their performance directly impacts indoor air quality. Existing floor drains, when embedded in the concrete floor, are prone to sewage seepage at the connection point, leading to water accumulation, bacterial growth, and odors. This makes later cleaning and maintenance difficult. Furthermore, conventional water-sealed floor drains have complex water-sealed zones that are difficult to disassemble and clean, resulting in sludge buildup and bacterial and odor accumulation over time. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pre-embedded anti-seepage and anti-odor floor drain. It not only has a good water seal and anti-odor effect, but also the interior of the floor drain is easy to disassemble and clean, does not easily produce odors, and has a good anti-seepage effect when pre-embedded in the ground. It can effectively solve the technical problems of existing floor drains having sanitary dead corners in the water seal area and easy water seepage at the connection between the floor drain and the ground.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0005] One technical solution of this utility model provides a pre-embedded anti-seepage and anti-odor floor drain, including a floor drain shell and a dirt intercepting basket and a water seal anti-odor inner core disposed in the inner cavity of the floor drain shell. The top opening of the floor drain shell forms a water inlet and the bottom opening forms a water outlet. A load-bearing filter plate is covered on the water inlet and a drain pipe is connected to the water outlet. The dirt intercepting basket is located between the load-bearing filter plate and the water seal anti-odor inner core.

[0006] The outer wall of the drain shell is provided with a water-stop ring extending outward. The water-stop ring is embedded in the ground base layer. A support ring is provided below the water-seal anti-odor core. The upper and lower ends of the support ring abut against the water-seal anti-odor core and the drain pipe, respectively. A water flow channel is opened on the side of the support ring. Sewage flows through the load-bearing filter plate, the intercepting basket, the water-seal anti-odor core and the support ring in sequence before entering the drain pipe.

[0007] Wastewater undergoes initial filtration through a load-bearing filter plate and flows into the drain casing through the inlet. A trap further filters impurities. The wastewater flows sequentially through the trap, the water-sealed odor-proof core, and the support ring before finally being discharged through the outlet pipe to the municipal sewage pipe or an external wastewater collection device. After drainage, some wastewater remains within the water-sealed odor-proof core, forming a water seal zone that prevents odors from flowing back into the room. The support ring provides support for the water-sealed odor-proof core, improving its stability during water flow and water sealing.

[0008] Furthermore, the water-sealed odor-proof inner core includes a water collection hopper and a water-sealed cup connected below the water collection hopper. The water collection hopper and the water-sealed cup are coaxial, and a suspension step is provided at the water inlet. The upper opening end of the water collection hopper is suspended on the suspension step, and the diameter of the lower opening end of the water collection hopper is smaller than the diameter of the upper opening end. The lower opening end of the water collection hopper extends into the interior of the water-sealed cup. Wastewater that has been filtered through the trap is collected by the water collection hopper and flows into the water-sealed cup below. After overflowing, it flows into the bottom of the drain casing and is finally discharged through the drain pipe. A water seal area can be formed between the bottom side wall of the water collection hopper and the water-sealed cup to store water, which plays a role in preventing odors.

[0009] Furthermore, a connecting plate is fixed on the inner side wall of the lower part of the water collection hopper, and a vertical threaded rod is fixed on the bottom of the water seal cup. The threaded rod is threadedly connected to the connecting plate, which improves the flexibility of assembly and disassembly between the water collection hopper and the water seal cup, facilitates transportation and storage, and allows for quick assembly to form a stable connection.

[0010] Furthermore, the inner depth of the water seal cup is no less than 50mm. The water level is no less than 50mm, meeting the national standard for water seal height and ensuring a good water seal odor prevention effect.

[0011] Furthermore, the drain casing and the water-stop ring are integrally molded, and the angle between the outer circumference edge of the water-stop ring and the horizontal plane is less than 30 degrees. During use, the water-stop ring is embedded in the concrete base layer of the floor, which not only improves the connection stability between the drain and the floor but also prevents sewage from seeping down through the installation gap between the drain and the floor base, thus preventing water seepage. The downward-sloping design of the water-stop ring prevents sewage from accumulating between the water-stop ring and the drain casing.

[0012] Furthermore, the load-bearing filter plate includes a main frame and several parallel and spaced twisted ribs inside the main frame. The main frame and the twisted ribs are integrally formed. The angle between the twisted ribs and the horizontal plane is 30 to 90 degrees, which improves the load-bearing capacity of the load-bearing filter plate while ensuring the filtration of sewage and debris. Several open grooves are provided on the upper part of the twisted ribs to play a role in anti-slip and filtration.

[0013] Furthermore, a groove is provided at the connection between the outlet and the drain pipe. The support ring is cylindrical, with its outer diameter being the same as the inner diameter of the groove and smaller than the outer diameter of the water seal cup. The bottom of the support ring is embedded in the groove and abuts against the drain pipe. The bottom end of the water flow channel on the support ring is flush with the upper edge of the groove. The support ring can be used to support the water seal cup, ensuring the connection stability between the water collection hopper and the water seal cup, while also ensuring that sewage flows into the drain pipe through the water flow channel, preventing water accumulation.

[0014] Furthermore, a sealing ring with a U-shaped cross-section is wrapped around the upper opening edge of the water collection hopper. The sealing ring forms an interference fit with the water collection hopper and the suspension step, thereby improving the sealing performance at the connection between the water collection hopper and the inlet, ensuring that all sewage is filtered through the intercepting basket and then collected in the water collection hopper before flowing into the water seal tray.

[0015] This utility model has the following beneficial effects:

[0016] The pre-embedded anti-seepage and anti-odor floor drain provided by this utility model improves the anti-seepage performance by setting a water-stop ring, and improves the anti-odor effect by setting a water-seal anti-odor inner core to form a water-seal zone. In addition, the water-seal anti-odor inner core can be quickly disassembled and installed, making it easy to remove the sludge accumulated at the bottom of the water-seal zone and preventing the generation of odors. The floor drain of this utility model is easy to disassemble and assemble quickly, convenient to transport, has low manufacturing cost, and is easy to mass-produce. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] refer to Figures 1 to 4This utility model provides a pre-embedded waterproof and odor-proof floor drain, including a floor drain shell 1 and a sludge-collecting basket 2 and a water-sealed odor-proof inner core 3 disposed within the inner cavity of the floor drain shell 1. The floor drain shell 1 has an inlet 11 at the top and an outlet 12 at the bottom. A load-bearing filter plate 4 covers the inlet 11, and a drain pipe 5 is connected to the outlet 12. The sludge-collecting basket 2 is located between the load-bearing filter plate 4 and the water-sealed odor-proof inner core 3. Both the sludge-collecting basket 2 and the load-bearing filter plate 4 have several water passage holes, the diameter of which is smaller than that of the water passage holes on the load-bearing filter plate 4. A water-stop ring 13 extending outwards is provided around the outer wall of the floor drain shell 1, and the water-stop ring 13 is embedded in the ground base layer. A support ring 6 is provided below the water seal odor-proof inner core 3. The upper and lower ends of the support ring 6 abut against the water seal odor-proof inner core 3 and the drain pipe 5 respectively, providing support for the water seal odor-proof inner core 3 and improving the installation stability of the water seal odor-proof inner core 3 during water flow and water storage. A water flow channel 61 is opened on the side of the support ring 6. Sewage flows through the load-bearing filter plate 4, the intercepting basket 2, the water seal odor-proof inner core 3 and the support ring 6 in sequence before entering the drain pipe 5.

[0030] refer to Figure 2 and Figure 4 The water-sealed odor-proof inner core 3 includes a water collection hopper 31 and a water-sealed cup 32 connected below the water collection hopper 31. The water collection hopper 31 and the water-sealed cup 32 are coaxial. A suspension step 15 is provided at the water inlet 11. The upper opening end of the water collection hopper 31 is suspended on the suspension step 15. The sludge trap 2 is pressed above the water collection hopper 31. The water collection hopper 31 is funnel-shaped, with the diameter of the lower opening end smaller than the diameter of the upper opening end. The lower opening end of the water collection hopper 31 extends into the interior of the water-sealed cup 32. After the sludge trap 2 filters out impurities, all the sewage is collected through the water collection hopper 31 and flows into the water-sealed cup 32 below. After overflowing, it flows into the bottom of the drain shell 1 and is finally discharged through the drain pipe 5. A water seal area can be formed between the bottom side wall of the water collection hopper 31 and the water-sealed cup 32 to store water, which plays a role in preventing odor. A connecting plate 33 is fixed to the inner wall of the lower part of the water collection hopper 31, and a vertical threaded rod 34 is fixed to the bottom of the water seal cup 32. The threaded rod 34 is threadedly connected to the connecting plate 33, which improves the flexibility of assembly and disassembly between the water collection hopper 31 and the water seal cup 32, facilitates transportation and storage, and allows for quick assembly to form a stable connection. The water level in the water seal cup 32 is not less than 50mm, meeting the national standard water seal height and ensuring a good water seal odor prevention effect.

[0031] refer to Figure 1 and Figure 4The drain housing 1 and the water-stop ring 13 are integrally formed, and the angle between the outer circumference edge of the water-stop ring 13 and the horizontal plane is less than 30 degrees. During use, the water-stop ring 13 is embedded in the concrete base of the floor, which not only improves the connection stability between the drain and the floor but also prevents sewage from seeping down through the installation gap between the drain and the floor base, thus preventing water seepage. The downward-sloping design of the water-stop ring 13 prevents sewage from accumulating between the water-stop ring 13 and the drain housing 1.

[0032] refer to Figure 4 and Figure 5 The load-bearing filter plate 4 includes a main frame 41 and several parallel, spaced-apart twisted ribs 42 disposed inside the main frame 41. The main frame 41 and the twisted ribs 42 are integrally formed, and the twisted ribs 42 are formed by cutting and twisting on the main frame 41, which is simple, convenient and low-cost to process. The angle between the twisted ribs 42 and the horizontal plane is 30 to 90 degrees, preferably 90 degrees, which improves the load-bearing capacity of the load-bearing filter plate 4 while ensuring the filtration of sewage and impurities. The upper part of the twisted ribs 42 is provided with several open grooves 43, which serve as anti-slip and filtration functions.

[0033] refer to Figure 2 and Figure 4 A groove 14 is provided at the connection between the outlet 12 and the drain pipe 5. The support ring 6 is cylindrical, and its outer diameter is the same as the inner diameter of the groove 14 but smaller than the outer diameter of the water seal cup 32. The bottom of the support ring 6 is embedded in the groove 14 and abuts against the drain pipe 5. The bottom end of the water flow channel 61 on the support ring 6 is flush with the upper edge of the groove 14. The support ring 6 can be used to support the water seal cup 32, ensuring the connection stability between the water collection hopper 31 and the water seal cup 32, while also ensuring that sewage flows into the drain pipe 5 through the water flow channel 61 without water accumulation. A sealing ring 7 is wrapped around the upper opening edge of the water collection hopper 31. The sealing ring 7 has a U-shaped cross-section and forms an interference fit with the water collection hopper 31 and the suspension step 15. This improves the sealing performance of the connection between the water collection hopper 31 and the inlet 11, ensuring that all sewage is filtered through the intercepting basket 2 and collected by the water collection hopper 31 before flowing into the water seal cup 32.

[0034] The drain provided by this utility model has a water-stop ring embedded in the concrete layer of the ground. The drain shell 1 is connected to the external drainage ditch. After the wastewater is initially filtered by the load-bearing filter plate 4, it flows into the interior of the drain shell 1 through the inlet 11 and is further filtered by the intercepting basket 2. The wastewater is collected by the collection hopper 31 and flows into the water seal cup 32, overflowing to the bottom of the drain shell 1. Finally, it is discharged into the municipal sewage pipe or an external sewage collection device through the drain pipe 5. After drainage, some wastewater remains in the water seal anti-odor core 3 to form a water seal area, which plays a role in preventing odor from flowing back into the room from the drain pipe.
