Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to a full-diameter, high-flow-rate, odor-proof floor drain. Background Technology

[0002] For example, publication number "CN222101099U" discloses "a water-sealed anti-odor floor drain core," which includes a pull-out core with a filter port and a water outlet cylinder with water outlet holes on its side wall. The pull-out core is completely or partially inserted into the water outlet cylinder and sealed to it. The water outlet holes are positioned higher than the filter port, and an installation kit is provided on the water outlet cylinder. The pull-out core includes an insertion part, and the filter port is located at the bottom of the insertion part. However, in practical applications, this type of anti-odor floor drain core, due to its anti-odor structure, results in a low drainage flow rate. Summary of the Invention

[0003] In view of the problem mentioned in the background art that the existing technology has a low drainage flow rate due to the setting of the anti-odor structure, the present invention provides a full-diameter large flow anti-odor floor drain, which can ensure that the floor drain has a sufficient anti-odor effect and can ensure smooth water flow and sufficient drainage volume during the drainage process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A full-bore, high-flow-rate odor-proof floor drain includes an upper panel assembly connected to an odor-proof drain core. The odor-proof drain core includes a perforated support member. An umbrella-shaped odor-proof core is connected to the side of the perforated support member away from the upper panel assembly. The umbrella-shaped odor-proof core includes a central connecting portion connected to the perforated support member and an umbrella-shaped elastic sheet connected to the central connecting portion. The umbrella-shaped elastic sheet fits snugly against the perforated support member.

[0006] As a crucial component of building drainage systems, floor drains play a vital role in connecting indoor floors to drainage pipes. After decades of development, traditional floor drain structures have evolved into two main technological approaches: water-sealed and mechanical-sealed. However, in practical applications, a persistent technical contradiction exists between odor prevention performance and drainage efficiency, a contradiction that has become a key bottleneck restricting the upgrading of floor drain products.

[0007] Water-sealed floor drains use a U-shaped or S-shaped water trap to form a water seal barrier, effectively preventing the backflow of sewer odors and harmful gases, offering a natural advantage in odor prevention through physical isolation. However, due to the inherent hydrodynamic characteristics of the water trap structure, these floor drains generally suffer from problems such as reduced drainage cross-section and increased water flow resistance. Experimental data shows that a standard 50mm diameter water-sealed floor drain can only achieve 60%-70% of its theoretical drainage capacity under full load conditions. In the event of heavy rain or sudden large-flow drainage demands, drainage lag is highly likely to occur, potentially even leading to backflow accidents. Furthermore, the water seal structure has an inherent defect of being prone to drying out and failure.

[0008] Mechanical seal floor drains use spring-loaded or magnetic sealing devices to achieve odor prevention through physical closure. While these products can achieve instantaneous high-flow-rate drainage, they reveal two major technical flaws in actual use: the durability of the mechanical seals is a significant issue, and the metal components are prone to corrosion and jamming in humid environments.

[0009] Therefore, based on the existing problems, this application provides an odor-proof drain core below the upper panel assembly. The odor-proof drain core includes a perforated support member with perforations to ensure drainage. In this application, the perforated support member is connected to a bulk odor-proof core. The umbrella-shaped odor-proof core includes a central connecting part that connects to the perforated support member. An umbrella-shaped elastic sheet is connected to the outside of the central connecting part. The umbrella-shaped elastic sheet is composed of an elastic material, including but not limited to silicone. Due to the material and structure of the umbrella-shaped elastic sheet, during drainage, the... The force of gravity on the water flow compresses the umbrella-shaped elastic sheet, causing it to contract and drain the water into the pipe. When drainage is not needed, the elastic sheet's resilience allows it to spring back to its original shape, ensuring it adheres to the perforated support and blocking the connection between the support and the pipe. This prevents odor buildup. Because this application relies on the elastic contraction and recovery of the umbrella-shaped elastic sheet, without complex mechanical or spring structures, it avoids creating many hard-to-clean cleaning nooks and ensures greater stability during use.

[0010] Preferably, the hollow support member includes a central support portion, which engages with the umbrella-shaped odor-proof core. By engaging with the umbrella-shaped odor-proof core, the central support portion allows water to flow downwards through the outer ring of the central support portion, thereby causing the umbrella-shaped elastic sheet to contract and ensuring the water flow rate.

[0011] Preferably, the perforated support includes an outer edge plate connected to the upper panel assembly. A plurality of connecting ribs connect the outer edge plate to the central support, and perforations are formed between each connecting rib. The connecting ribs ensure reliable connection between the outer edge plate and the central support, while also creating perforations between them to ensure sufficient water flow. When the umbrella-shaped elastic sheet opens, drainage can occur through these perforations.

[0012] Preferably, the perforated support includes an outer edge plate with a drain placement groove. An inner drain ring is placed in the drain placement groove. The upper panel assembly includes a connecting cylinder, which is sleeved on the outside of the outer edge plate. The inner drain ring fits against the inner wall of the connecting cylinder. The drain placement groove on the outer edge plate, the inner drain ring in the groove, and the interlocking connection between the inner drain ring and the connecting cylinder ensure a tight seal between the outer edge plate and the connecting cylinder. This prevents water from flowing through this area and also prevents backflow of odors from the sewer pipe through this gap.

[0013] Preferably, the upper panel assembly includes a connecting cylinder with a panel placement groove. A panel base rubber ring is provided on the panel placement groove. An extension sleeve is fitted onto the connecting cylinder, and the panel base rubber ring conforms to the inner wall of the extension sleeve. The panel placement groove and panel base rubber ring are positioned between the connecting cylinder and the extension sleeve to ensure a tight connection between them, while preventing gaps between them to avoid water flow and ensuring odor prevention.

[0014] Preferably, the upper panel assembly includes a connecting cylinder, and the odor-proof drain core includes a main body that is fitted inside the connecting cylinder. The odor-proof drain core includes a limiting edge plate that abuts against the top of the connecting cylinder. By providing a limiting edge plate on the odor-proof drain core, the drain core can be engaged with the connecting cylinder via the limiting edge plate. During subsequent maintenance and cleaning, the odor-proof drain core can be quickly removed from the connecting cylinder, improving cleaning efficiency.

[0015] Preferably, the umbrella-shaped odor-proof core is provided with a central reinforcing groove, and a pressure cap is connected to the central reinforcing groove. The umbrella-shaped odor-proof core is clamped between the pressure cap and the hollow support member. By providing the central reinforcing groove and the pressure cap, the umbrella-shaped odor-proof core can be more securely connected to the hollow support member, preventing the umbrella-shaped odor-proof core from falling downwards and ensuring the stability of the connection.

[0016] Preferably, the hollow support member is provided with a protruding shaft, the pressure cap is provided with a connecting sleeve, and the connecting sleeve is provided with a protruding rib. The connecting sleeve is fitted onto the protruding shaft, and the protruding rib abuts against the protruding shaft. The hollow support member has a protruding shaft, and the pressure cap has a connecting sleeve, wherein the size of the connecting sleeve is larger than the size of the protruding shaft. The connecting sleeve has a protruding rib, which is a vertically raised structure inside the connecting sleeve. The protruding rib can better connect and fix the protruding shaft, thereby ensuring the connection stability between the pressure cap and the umbrella-shaped odor-proof core.

[0017] Preferably, the upper panel assembly includes a panel base with an embedded groove. A filter screen and a filter panel are connected within the embedded groove, with the filter screen located below the filter panel. The upper panel assembly includes a panel base with an embedded groove, which facilitates better connection and installation of the filter screen and filter panel. Both the filter screen and filter panel have a grid structure, which makes subsequent cleaning easier.

[0018] Preferably, the filter panel has a beveled edge near the filter screen, and the recessed groove includes a surrounding plate with a guide surface adapted to the bevel. The bevel and guide surface facilitate alignment of the filter panel with the recessed groove during installation, improving installation efficiency. For routine maintenance, installation can be completed simply by moving the filter panel above the recessed groove, making it convenient to use.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) It can ensure that the floor drain has sufficient anti-odor effect and that the water flow is smooth and the drainage volume is sufficient during the drainage process; (2) It can improve the filtration effect of debris, facilitate subsequent cleaning, and improve the efficiency of disassembly and installation.

[0021] (3) It can ensure the connection stability of the umbrella-shaped deodorizing core and ensure that the umbrella-shaped deodorizing core will not fall off the hollow support. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1:

[0036] like Figure 1 , 3 As shown, a full-bore, high-flow-rate odor-proof floor drain includes an upper panel assembly 11, an odor-proof floor drain core 2 connected to the upper panel assembly 11, an odor-proof floor drain core 2 including a hollow support member 3, an umbrella-shaped odor-proof core 4 connected to the side of the hollow support member 3 away from the upper panel assembly 11, an umbrella-shaped odor-proof core 4 including a central connecting part 41 connected to the hollow support member 3, and an umbrella-shaped elastic sheet 42 connected to the central connecting part 41, the umbrella-shaped elastic sheet 42 being fitted to the hollow support member 3.

[0037] As a crucial component of building drainage systems, floor drains play a vital role in connecting indoor floors to drainage pipes. After decades of development, traditional floor drain structures have evolved into two main technological approaches: water-sealed and mechanical-sealed. However, in practical applications, a persistent technical contradiction exists between odor prevention performance and drainage efficiency, a contradiction that has become a key bottleneck restricting the upgrading of floor drain products.

In the event of heavy rain or sudden large-flow drainage demands, drainage lag is highly likely to occur, potentially even leading to backflow accidents. Furthermore, the water seal structure has an inherent defect of being prone to drying out and failure.

[0039] Mechanical seal floor drains use spring-loaded or magnetic sealing devices to achieve odor prevention through physical closure. While these products can achieve instantaneous high-flow-rate drainage, they reveal two major technical flaws in actual use: the durability of the mechanical seals is a significant issue, and the metal components are prone to corrosion and jamming in humid environments.

[0040] Therefore, based on the existing problems, this application provides an odor-proof drain core 2 below the upper panel assembly 11. The odor-proof drain core 2 includes a hollow support member 3, which has a hollowed-out portion to ensure drainage. In this application, the hollow support member 3 is connected to a bulk odor-proof core, and the umbrella-shaped odor-proof core 4 includes a central connecting part 41, which is connected to the hollow support member 3. An umbrella-shaped elastic sheet 42 is connected to the outside of the central connecting part 41. The umbrella-shaped elastic sheet 42 is made of elastic material, including but not limited to silicone. Due to the material and structure of the umbrella-shaped elastic sheet 42, it ensures drainage during the drainage process. During operation, the water flow is compressed by gravity, causing the umbrella-shaped elastic sheet 42 to contract and drain the water into the pipe. When drainage is not required, the elastic sheet 42 recovers its elasticity, allowing it to conform to the perforated support 3 and blocking the connection between the support 3 and the pipe, thus preventing odor buildup. Since this application relies on the elastic contraction and recovery of the umbrella-shaped elastic sheet 42 without complex mechanical or spring structures, it avoids creating many hard-to-clean corners and ensures more stable operation.

[0041] like Figure 3 As shown, the hollow support 3 includes a central support portion 41, which engages with the umbrella-shaped anti-odor core 4. By engaging with the umbrella-shaped anti-odor core 4, the central support portion 41 allows water to flow downwards through the outer ring of the central support portion 41, thereby causing the umbrella-shaped elastic sheet 42 to contract and ensuring the flow rate of water.

[0042] like Figure 3As shown, the perforated support member 3 includes an outer edge plate 32, which is connected to the upper panel assembly 11. Several connecting ribs 33 connect the outer edge plate 32 to the central support part 41, and perforations 34 are provided between each connecting rib 33. The connection between the outer edge plate 32 and the central support part 41 is ensured by the connecting ribs 33, which also form perforations 34 between the connecting ribs 33. These perforations 34 ensure the flow rate of water, allowing drainage when the umbrella-shaped elastic sheet 42 is opened.

[0043] like Figure 1 As shown, the upper panel assembly 11 includes a connecting cylinder 12, and the odor-proof drain core 2 includes a main body 21, which is sleeved inside the connecting cylinder 12. The odor-proof drain core 2 includes a limiting edge plate 22, which abuts against the top of the connecting cylinder 12. By providing the limiting edge plate 22 on the odor-proof drain core 2, the odor-proof drain core 2 can be engaged with the connecting cylinder 12 by the limiting edge plate 22. During subsequent maintenance and cleaning, the odor-proof drain core 2 can be quickly removed from the connecting cylinder 12, improving cleaning efficiency.

[0044] like Figure 3 , 4 As shown, the umbrella-shaped odor-proof core 4 is provided with a central reinforcing groove 43, and a pressure cap 6 is connected to the central reinforcing groove 43. The umbrella-shaped odor-proof core 4 is clamped between the pressure cap 6 and the hollow support member 3. By providing the central reinforcing groove 43 and the pressure cap 6, the umbrella-shaped odor-proof core 4 can be more firmly connected to the hollow support member, preventing the umbrella-shaped odor-proof core 4 from falling downwards and ensuring the stability of the connection.

[0045] like Figure 4 As shown, the hollow support member 3 is provided with a protruding shaft 36, and the pressure cap 6 is provided with a connecting sleeve 61. The connecting sleeve 61 is provided with a protruding rib 62. The connecting sleeve 61 is fitted onto the protruding shaft 36, and the protruding rib 62 abuts against the protruding shaft 36. The hollow support member 3 is provided with a protruding shaft 36, and the pressure cap 6 is provided with a connecting sleeve 61. The connecting sleeve 61 is larger than the protruding shaft 36. The connecting sleeve 61 is provided with a protruding rib 62, which is a vertical strip structure protruding inside the connecting sleeve 61. The protruding rib 62 can better connect and fix the protruding shaft 36, thereby ensuring the connection stability between the pressure cap 6 and the umbrella-shaped odor-proof core 4.

[0046] Example 2:

[0047] like Figure 1 , 3As shown, a full-bore, high-flow-rate odor-proof floor drain includes an upper panel assembly 11, an odor-proof floor drain core 2 connected to the upper panel assembly 11, an odor-proof floor drain core 2 including a hollow support member 3, an umbrella-shaped odor-proof core 4 connected to the side of the hollow support member 3 away from the upper panel assembly 11, an umbrella-shaped odor-proof core 4 including a central connecting part 41 connected to the hollow support member 3, and an umbrella-shaped elastic sheet 42 connected to the central connecting part 41, the umbrella-shaped elastic sheet 42 being fitted to the hollow support member 3.

The odor-proof drain core 2 includes a hollow support member 3, which has a hollowed-out portion to ensure drainage. In this application, the hollow support member 3 is connected to a bulk odor-proof core, and the umbrella-shaped odor-proof core 4 includes a central connecting part 41, which is connected to the hollow support member 3.

[0051] like Figure 2As shown, the upper panel assembly 11 includes a panel base 15, which includes an embedded groove 151. A filter screen 16 and a filter panel 17 are connected within the embedded groove 151, with the filter screen 16 located below the filter panel 17. The upper panel assembly 11 includes a panel base 15, on which the embedded groove 151 is provided. The embedded groove 151 allows for better connection and installation of the filter screen 16 and the filter panel 17. The filter screen 16 is positioned below the filter panel 17, and both the filter screen 16 and the filter panel 17 have a grid-like structure, facilitating subsequent cleaning operations.

The recessed groove 151 includes a surrounding plate 152, and the surrounding plate 152 includes a guide surface 153 adapted to the bevel 171. The bevel 171 and guide surface 153 facilitate alignment between the filter panel 17 and the recessed groove 151 during installation, improving installation efficiency. For routine maintenance, installation can be completed simply by moving the filter panel 17 above the recessed groove 151, making it convenient to use.

[0055] Water-sealed floor drains use a U-shaped or S-shaped water trap to form a water seal barrier, effectively preventing the backflow of sewer odors and harmful gases, offering a natural advantage in odor prevention through physical isolation. However, due to the inherent hydrodynamic characteristics of the water trap structure, these floor drains generally suffer from problems such as reduced drainage cross-section and increased water flow resistance.

While these products can achieve instantaneous high-flow-rate drainage, they reveal two major technical flaws in actual use: the durability of the mechanical seals is a significant issue, and the metal components are prone to corrosion and jamming in humid environments.

[0057] Therefore, based on the existing problems, this application provides an odor-proof drain core 2 below the upper panel assembly 11. The odor-proof drain core 2 includes a hollow support member 3, which has a hollowed-out portion to ensure drainage. In this application, the hollow support member 3 is connected to a bulk odor-proof core, and the umbrella-shaped odor-proof core 4 includes a central connecting part 41, which is connected to the hollow support member 3.
