Description

Technical Field

[0001] The invention relates to the technical field of wastewater sanitary pipeline devices, in particular to deodorizing seals. Background Art

[0002] With the continuous development of modern life and the increasing demand for comfortable quality of life, the functions of modern bathrooms have been deeply expanded. Sunken bathrooms have a larger space and beautiful appearance design, and are becoming more and more popular. However, the drainage system of the sunken bathroom is pre-buried in the lower layer of the ground, which is very inconvenient to clean. It is necessary to set up a reasonable pipe system before laying the floor tiles and cement. The drainage and deodorization of the bathroom need to rely on the same-level drainage floor drain with a water seal. The same-level drainage floor drain is a kind of pipeline component pre-set in the bathroom floor. Its purpose is to block the odor during the use of the bathroom. When the same-level drainage floor drain is installed in the early stage, the position needs to be set in advance, but due to the error of the early construction, the actual position of the floor drain panel may not be in the expected position; the traditional same-level drainage floor drain is very troublesome to clean because the internal channel of the floor drain is too narrow and the cleaning tools cannot penetrate into the inside; and traditional floor drains all have the common problem of small flow. For example, a Chinese patent with publication number CN202672324U discloses a new type of odor-proof floor drain and provides the following technical solution: the utility model discloses a new type of odor-proof floor drain, which relates to a water supply and drainage product installed in a fixed building for sewage discharge. The odor-proof floor drain includes a mounting seat, a drain hole, an odor-proof component, and a water leakage component, etc. The disclosed technical feature is to provide a mounting seat with a split structure, which is mainly composed of a base and a removable seal plug-in upper body connected to the top of the base. The upper body can be appropriately made high when leaving the factory, so that in the actual construction process, if the mounting seat is installed too high on the ground, it is only necessary to adjust the height of the upper body by cutting, so it brings great convenience to the construction. However, the above-mentioned new type of odor-proof floor drain cannot meet the requirements of large-flow drainage, nor does it have an adjustment function. While failing to achieve secondary drainage, it also cannot solve the problem of adjustable functions due to inaccurate early position positioning or unsatisfactory panel position. Summary of the invention

[0003] The present invention solves the problems of the prior art that it cannot be adjusted, cannot drain water at a large flow rate and is not aesthetically pleasing, and proposes an adjustable secondary drainage floor drain system, which achieves the purposes of being aesthetically pleasing, being able to drain water at a large flow rate, being easy to maintain, being adjustable and having a secondary drainage function.

[0004] To achieve the above object, the present invention adopts the following technical solutions: An adjustable secondary drainage floor drain system comprises a vertical floor drain, a horizontal floor drain and a toilet assembly, wherein the vertical floor drain and the horizontal floor drain are both provided with a heightened sleeve body and an umbrella-shaped deodorizing core; the umbrella-shaped deodorizing core is fixed on a deodorizing core support through a deodorizing core pressure cap, the vertical floor drain is inserted into a reserved pipe for interlayer drainage through a socket below the heightened sleeve body, the horizontal floor drain is connected to a drainage pipeline system on the same floor through a reducing pipe, and the toilet assembly is connected to the drainage pipeline system on the same floor through accessories.

[0005] The advantage of this design is that through the combined use of vertical floor drains and horizontal floor drains, it can be flexibly applied in different drainage demand scenarios. The heightened sleeve body provides a height adjustment function, and the umbrella-shaped anti-odor core effectively prevents the backflow of odor while ensuring smooth drainage.

[0006] Preferably, the top of the deodorizing core support is a sunken circular groove, in which a fishbone-shaped filter is installed. The fishbone-shaped filter adopts a fishbone-shaped design with a middle circular hole in the center. The middle circular hole is fixed to the truncated cone protrusion on the deodorizing core support, and the outer diameter of the lower circular periphery of the deodorizing core support is smaller than the inner diameter of the upper part of the heightened sleeve body.

[0007] The advantage of this design is that the herringbone filter can effectively prevent debris from entering the pipe, especially hair and other fine particles, while providing a good filtering effect; the sunken circular groove design enhances the sealing of the deodorizing core and avoids air leakage.

[0008] Preferably, the tops of the vertical floor drains and the horizontal floor drains are provided with a plastic panel base and a floor drain metal panel, the circumference of the deodorizing core support is provided with soft plastic, and the center of the plastic panel base is provided with a sunken stepped circular hole adapted to the deodorizing core support, and the soft plastic seals the gap between the deodorizing core support and the plastic panel base.

[0009] The advantage of this design is that the soft plastic seal enhances the sealing between the deodorizing core support and the base, preventing odor and water leakage; the sunken stepped circular holes provide better fit and support for the deodorizing core support, ensuring the stability of the system.

[0010] Preferably, the plastic panel base is provided with bevel chamfers around the top, and the floor drain metal panel is provided with metal panel chamfers around the top. The floor drain metal panel and the plastic panel base are fixed by the bevel chamfers and the metal panel chamfers, and the metal panel chamfer is a bevel chamfer structure.

[0011] The advantage of this design is that the beveled and chamfered design can not only enhance the firmness of the structure, but also improve the aesthetics and prevent the sharp angles of the metal panel from causing damage to the surrounding environment and personnel.

[0012] Preferably, the circumferential edge of the umbrella-shaped deodorizing core has a folded edge; when no water flows down, the umbrella-shaped deodorizing core is in an open state, and the folded edge is tightly fitted with the supporting circumference of the deodorizing core; when water flows down from above, the umbrella-shaped deodorizing core shrinks and closes.

[0013] The advantage of this design is that the umbrella-shaped deodorizing core is designed with folded edges, which will automatically close when there is no water flow to prevent odor from overflowing; when water flows through, the deodorizing core can automatically collapse to ensure smooth water flow, thus having the deodorizing function without affecting drainage efficiency.

[0014] Preferably, the vertical floor drain is inserted into the interlayer drainage reserved pipe through the socket below the vertical floor drain heightening sleeve body; a plurality of secondary drainage protrusions and a plurality of guide rib grooves are provided below the vertical floor drain heightening sleeve body, the secondary drainage protrusions are distributed around the circumference of the socket, and the guide rib grooves are distributed around the circumference of the socket; cutting grooves are provided at certain intervals above the heightening sleeve body.

[0015] The advantage of this design is that the secondary drainage protrusions and guide rib grooves can effectively guide the accumulated water for secondary drainage while avoiding the accumulation of impurities; the cutting grooves of the heightening sleeve body provide flexible installation adjustments to adapt to different lowering requirements.

[0016] Preferably, the horizontal floor drain is connected to the reducer through the horizontal floor drain heightening sleeve body, and then connected to the same-floor drainage pipe system. The reducer is a flat-to-round structure, and the drainage outlet connected to the horizontal floor drain heightening sleeve body is a horizontal flat pipe.

[0017] The advantage of this design is that the horizontal floor drain design adopts a flat-to-round structure, which makes the drain outlet have higher drainage efficiency while saving space, and is suitable for a variety of different scenarios.

[0018] Preferably, the toilet assembly includes a toilet, a toilet water tank and a water tank frame, the toilet is a hidden wall-mounted type, the toilet water tank and the water tank frame are hidden in a false wall, and the same-floor drainage pipe system is installed on a cast-in-place floor.

[0019] The advantage of this design is that the hidden toilet assembly can enhance the overall aesthetics of the bathroom and save space. At the same time, the connection with the drainage system on the same floor also ensures better drainage effect.

[0020] Preferably, the umbrella-shaped deodorizing core is made of soft rubber material, and the soft plastic is made of secondary injection molding and is integrated with the deodorizing core support.

[0021] The advantage of this design is that the soft rubber material makes the deodorizing core have better elasticity and sealing, and the secondary injection-molded soft plastic enhances the overall sealing between the deodorizing core support and the base, thus improving the durability and deodorizing effect of the system.

[0022] Compared with the prior art, the invention has the following beneficial effects.

[0023] 1. The present invention provides a flexible drainage solution through the combination of vertical and horizontal floor drains. The vertical floor drain is inserted into the reserved drainage pipe of the interlayer by raising the main body of the sleeve to ensure smooth drainage of the interlayer; the horizontal floor drain is connected to the drainage pipeline system on the same floor through a different diameter pipe to adapt to different drop plate heights and drainage requirements. The secondary drainage protrusion and the guide rib groove design ensure that the accumulated water between the floor drain and the ground can be effectively discharged to avoid the adverse effects of accumulated water. The height adjustment function of the overall system enables the floor drain to adapt to different installation conditions, further improving the drainage efficiency and installation flexibility of the floor drain.

[0024] 2. The present invention adopts an umbrella-shaped deodorizing core in terms of deodorization, and realizes automatic closure and opening through the folding edge design, which prevents the odor from flowing back without affecting the drainage. When water flows down, the deodorizing core can automatically shrink to ensure the smooth flow of water, and when there is no water flow, the folding edge fits tightly, and the deodorizing effect is significant. In addition, the deodorizing core support is equipped with a fishbone filter, which can effectively intercept hair and other debris, making cleaning easier. The full-diameter design and detachable structure make the later cleaning and maintenance easier. Whether it is the cleaning of debris or the cleaning of the deodorizing core, it can be easily operated, reducing the cumbersome maintenance process.

[0025] 3. The present invention adopts bevel chamfering and metal panel chamfering structure to ensure the close fit between the metal panel of the floor drain and the plastic base, thereby increasing the stability and firmness of the structure. At the same time, the chamfering design makes the surface of the floor drain smooth without sharp angles, effectively avoiding damage caused by sharp angles. The application of soft plastic sealing design and sunken circular groove strengthens the sealing between the deodorizing core and the base, ensuring a good deodorizing effect. The overall design not only improves the durability of the system, but also makes the appearance of the floor drain after installation more concise and beautiful, which meets the aesthetic requirements of modern bathrooms.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings. The proportions of the components are not drawn according to the actual proportions, and the proportions and sizes shown in the accompanying drawings should not limit the substantial technical scheme of the present invention. These embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described.

[0036] See also Figures 1 to 8 As shown, an adjustable secondary drainage floor drain system includes a vertical floor drain 1 and a horizontal floor drain 2 and a toilet assembly 3. The vertical floor drain 1 and the horizontal floor drain 2 are both provided with a heightened sleeve body and an umbrella-shaped deodorizing core 1.3; the umbrella-shaped deodorizing core 1.3 is fixed on the deodorizing core support 1.4 through a deodorizing core pressure cap 1.5, the vertical floor drain 1 is inserted into the interlayer drainage reserved pipe through the socket below the heightened sleeve body 1.1, the horizontal floor drain 2 is connected to the same-layer drainage pipeline system 9 through a reducing pipe connection 6, and the toilet assembly 3 is connected to the same-layer drainage pipeline system 9 through accessories. Among them, the schematic diagram of the deodorizing core support structure, the schematic diagram of the fishbone filter structure, the schematic diagram of the plastic panel base structure, and the schematic diagram of the floor drain metal panel structure are not shown.

[0037] like Figure 1In one embodiment shown, Figure 1 The schematic diagram of the overall structure of an embodiment of an adjustable secondary drainage floor drain system of the present invention. The adjustable secondary drainage floor drain system designed by the present invention includes a vertical floor drain 1, a horizontal floor drain 2 and a toilet assembly 3. Both the vertical floor drain and the horizontal floor drain are equipped with a heightened sleeve body 1.1, wherein the vertical floor drain is connected to the reserved drainage pipe of the interlayer through the socket below the heightened sleeve body, and the horizontal floor drain is connected to the drainage pipe system 9 on the same floor through a reducing pipe connection 6. The toilet assembly 3 includes a wall-mounted toilet 3, a toilet water tank 4 and a water tank frame 5, wherein the toilet water tank and the water tank frame are hidden in a false wall, thereby achieving an aesthetically pleasing appearance design. All components are connected to the drainage pipe system 9 on the same floor, and the system is installed on a cast-in-place floor 8.

[0038] In another embodiment, the present invention is designed as a vertical / horizontal floor drain with super large flow, displaceable eccentricity and easy to clean, which is composed of a system solution, which is composed of a vertical floor drain 1, a horizontal floor drain 2, a toilet 3, a toilet tank 4, a water tank frame 5, a pipe system composed of a different diameter pipe connecting a flat turn 6, a vertical inspection port 7, a cast-in-place floor 8, and other pipe fittings and pipes, a total of nine parts. The vertical floor drain 1 is suitable for interlayer drainage, and is inserted into the reserved DN50 pipe through the socket below the heightening sleeve body; the horizontal floor drain 2 is suitable for same-floor drainage, and is connected to the same-floor drainage pipe system 9 above the cast-in-place floor 8 through the different diameter pipe connecting a flat turn 6; the toilet 3 is a hidden wall-mounted type, and the toilet tank 4 and the water tank frame 5 are hidden in the false wall and connected to the same-floor drainage pipe system 9 through accessories.

[0039] The advantage of this design is that, first of all, through the combination of vertical and horizontal floor drains, the system can provide flexible drainage solutions under different environments and usage requirements. The vertical floor drain is connected to the interlayer drainage pipe by raising the main body of the sleeve to ensure that the interlayer drainage problem can be handled, especially in high-rise buildings, effectively solving the drainage problem of high floors; the horizontal floor drain is connected to the drainage system on the same floor through a reducer, so that the drainage function can still maintain high efficiency when the horizontal space is limited. This flexible design is highly adaptable and can be adjusted according to the drainage needs of different buildings, greatly improving the drainage efficiency and the applicability of the system. Secondly, the design of the toilet assembly also fully considers the needs of modern families for aesthetics and space utilization. By adopting a hidden wall-mounted toilet and hiding the toilet tank and tank rack in the false wall, it not only improves the cleanliness of the bathroom, but also saves space to the maximum extent, making the overall layout of the bathroom more concise and atmospheric, which meets the dual needs of modern families for aesthetics and practicality. The hidden design of the toilet tank and tank rack also reduces the visual conflict caused by the exposure of the traditional toilet tank, making the space look more open and tidy. Finally, the design of the same-floor drainage piping system makes all drainage components centralized and unified, installed on the cast-in-place floor, avoiding the complicated upper and lower pipe layout problems, greatly simplifying the installation process, and improving construction efficiency. In addition, the design of the entire system also makes later maintenance and repair more convenient. Since all components are easy to access and disassemble, users can easily clean and repair, avoiding problems caused by poor drainage or blockage, and extending the service life of the system.

[0040] Therefore, the present invention optimizes drainage performance and improves the aesthetics of the space through flexible design, and simplifies the installation and maintenance process. Its modular and adjustable characteristics provide efficient solutions for different building environments, which not only meet the needs of daily use, but also provide convenience for future maintenance and cleaning.

[0041] like Figure 2 and Figure 3 In one embodiment shown, Figure 2 This is a cross-sectional view of a vertical floor drain of an embodiment of an adjustable secondary drainage floor drain system of the present invention. Figure 3The schematic diagram of the vertical floor drain structure of an embodiment of an adjustable secondary drainage floor drain system of the present invention. The adjustable secondary drainage floor drain system designed by the present invention includes a vertical floor drain 1 and a horizontal floor drain 2, each of which is equipped with a heightened sleeve body 1.1 and an umbrella-shaped deodorizing core 1.3. The umbrella-shaped deodorizing core is fixed to the deodorizing core support 1.4 by a deodorizing core pressure cap 1.5. A sunken annular groove is designed above the deodorizing core support 1.4, and a fishbone-shaped filter screen 1.6 is installed in the groove. It has a unique fishbone-shaped design, with a circular hole in the middle, which is fixed to the truncated cone protrusion on the deodorizing core support 1.4. The outer diameter of the circular circumference below the deodorizing core support 1.4 is smaller than the inner diameter above the heightened sleeve body 1.1, ensuring the precise fit of the components. The top of the vertical floor drain and the horizontal floor drain are both equipped with a plastic panel base 1.2 and a floor drain metal panel 1.7. The odor-proof core support 1.4 is surrounded by soft plastic, and the center of the plastic panel base 1.2 is provided with a sunken stepped circular hole adapted to the odor-proof core support. The soft plastic plays a sealing role in it, effectively preventing the gap between the odor-proof core support and the plastic panel base from leaking odor. The plastic panel base 1.2 is provided with beveled chamfers around it, and the floor drain metal panel 1.7 is also provided with chamfers around it. The two are fixed by the coordination of the chamfers. The metal panel chamfer adopts a beveled chamfer structure, which not only improves the firmness, but also enhances the aesthetics of the product.

[0042] The circumferential edge of the umbrella-shaped deodorizing core 1.3 has a folded edge design. When there is no water flow, the umbrella-shaped deodorizing core is in an open state, and the folded edge fits tightly with the deodorizing core support 1.4, effectively preventing the leakage of odor. When water flows through, the umbrella-shaped deodorizing core will shrink and close, ensuring smooth drainage while avoiding reverse penetration of odor. The vertical floor drain is connected to the reserved drainage pipe of the interlayer through the socket under the heightening sleeve body, and the drainage performance is further optimized by the design of several secondary drainage protrusions 1.1.1 and guide rib grooves 1.1.2. The secondary drainage protrusions are distributed around the circumference of the socket, and the guide rib grooves are also distributed around the socket, helping to guide the flow of accumulated water and debris, avoiding water flow being blocked or debris accumulation. Several cutting grooves are also designed above the heightening sleeve body 1.1, so that the heightening sleeve body can be adjusted as needed in different installation environments, providing a flexible installation solution to meet the needs of different buildings. The umbrella-shaped deodorizing core 1.3 is made of highly elastic soft rubber material, which provides good elasticity and sealing performance, while the soft plastic is integrated with the deodorizing core support 1.4 through a secondary injection molding process, which enhances the sealing effect between the deodorizing core and the base and further improves the deodorizing capability of the system.

[0043] The design of this system significantly improves the performance of floor drains and drainage systems, especially in terms of drainage, sealing, deodorization and durability. First of all, through the combination of vertical floor drains and horizontal floor drains, the system can adapt to different drainage needs, especially in complex building environments, vertical or horizontal floor drains can be selected as needed to provide a flexible and efficient drainage solution. The connection between the heightened sleeve body of the vertical floor drain and the reserved drainage pipe of the interlayer ensures smooth drainage of the interlayer, especially in scenes such as high floors or basements, avoiding the problem of poor drainage. The horizontal floor drain is connected to the drainage pipeline system on the same floor through a reducing pipe connection, which can make full use of limited space, maintain good drainage effect, and adapt to the connection requirements of different drainage pipes. Secondly, the deodorization function has been fully optimized in the system design. The innovative design of the umbrella-shaped deodorization core enables the floor drain to close automatically when there is no water flow to prevent odor backflow; and when the water flows down, the umbrella-shaped deodorization core can shrink quickly to ensure smooth water flow without affecting drainage efficiency. The soft rubber material of the deodorizing core not only improves elasticity and sealing, but also ensures durability in long-term use. In addition, the fishbone filter on the deodorizing core support can effectively filter out hair, dust and other debris, avoid pipe blockage, improve the self-cleaning performance of the floor drain, and reduce the difficulty of cleaning.

[0044] The chamfer design of the plastic panel base and the metal panel of the floor drain not only enhances the stability and durability of the structure, but also avoids damage to personnel and the environment caused by sharp angles. The soft plastic sealing design enhances the sealing between the deodorizing core and the base, effectively isolates water and air, further prevents the leakage of odors, and ensures a fresh sanitary environment. The sunken annular groove and stepped circular hole design make the deodorizing core and filter mesh fit more accurately with the base, ensuring better sealing effect and system stability.

[0045] In addition, the design of the secondary drainage protrusion and the guide rib groove greatly improves the drainage efficiency. These designs enable the floor drain to guide the water flow more effectively, avoiding the accumulation of water and debris around the floor drain. Especially in environments that require efficient drainage, these designs can help the drainage system to dredge the water flow more quickly, reducing the risk of water accumulation and poor drainage. At the same time, the design of the cutting groove further enhances the adjustability of the heightening sleeve body, allowing the system to flexibly cope with different installation environments and reducing the difficulties and limitations during the installation process.

[0046] In general, the adjustable secondary drainage floor drain system designed by the present invention optimizes the drainage effect, improves the anti-odor performance, and enhances the durability of the system through precise structural design and high-quality material application, while also improving the flexibility of installation and the convenience of subsequent maintenance.

[0047] like Figure 4 and Figure 5 In one embodiment shown, Figure 4 This is a cross-sectional view of a horizontal floor drain of an embodiment of an adjustable secondary drainage floor drain system of the present invention. Figure 5 The horizontal floor drain structure schematic diagram of an embodiment of an adjustable secondary drainage floor drain system of the present invention. The horizontal floor drain 2 of the present invention is suitable for same-floor drainage. The horizontal floor drain scheme and the vertical floor drain scheme have the same accessories except for the floor drain heightening sleeve body. The horizontal floor drain 2 is connected to the reducer 6 through the horizontal floor drain heightening sleeve body 2.1. The reducer 6 adopts a flat-to-round structure to connect the drain outlet to the horizontal floor drain heightening sleeve body 2.1. The drain outlet is in the form of a horizontal flat tube, and finally the water flow is introduced into the same-floor drainage pipeline system 9.

[0048] The advantage of this design is that the flat-to-round structure of the reducer effectively transitions pipes of different sizes and shapes, ensuring smooth drainage and providing a flexible installation solution in places with relatively small spaces. The drainage outlet of the horizontal flat pipe adapts to different drainage needs, making the installation more flexible, especially suitable for environments with limited space or special layouts, avoiding the limitations of traditional drainage pipes.

[0049] like Figure 6 In one embodiment shown, Figure 6 The schematic diagram of the main structure of the vertical floor drain heightening sleeve of an embodiment of an adjustable secondary drainage floor drain system of the present invention. There are secondary drainage protrusions 1.1.1 and guide rib grooves 1.1.2 below the vertical floor drain heightening sleeve main body 1.1. After the floor drain is inserted into the DN50 pipe for installation, water accumulates in the gap between the floor drain and the ground. After the impurities such as mud and sand are filtered through the secondary drainage protrusions 1.1.1, secondary drainage is carried out through the guide rib grooves 1.1.2. In addition, there are cutting grooves at intervals above the vertical floor drain heightening sleeve main body 1.1. The heightening sleeve can be cut according to the actual lowering requirements to obtain the required height, thereby adjusting the overall height of the floor drain.

[0050] like Figure 7 In one embodiment shown, Figure 7The schematic diagram of the structure of an umbrella-shaped deodorizing core of an embodiment of an adjustable secondary drainage floor drain system of the present invention. The circumferential edge of the umbrella-shaped deodorizing core 1.3 is provided with a folded edge 1.3.1, and the umbrella-shaped deodorizing core 1.3 is fixed on the deodorizing core support 1.4 through the deodorizing core pressure cap 1.5. When there is no water flowing down, the umbrella-shaped deodorizing core 1.3 is in an open state, and the folded edge 1.3.1 can fit tightly with the circumference of the deodorizing core support 4, which can prevent the odor from overflowing from below and achieve the deodorizing effect; when there is water flowing down from above, the umbrella-shaped deodorizing core 1.3 will shrink and close like an umbrella due to its soft rubber material, allowing the water to flow through. The outer diameter of the circumference below the deodorizing core support 1.4 is smaller than the inner diameter above the vertical row 1.1 of the floor drain heightening sleeve body, which can adjust the panel position and solve the problem of inaccurate positioning and unsatisfactory panel position in the early stage. When cleaning in the later stage, take out the deodorizing core support 1.4, and the floor drain as a whole will achieve "full diameter", which is very convenient for later cleaning and maintenance. The top of the deodorizing core support 1.4 is designed as a sunken circular groove, which can accommodate the fishbone filter 1.6; the fishbone filter 1.6 adopts a fishbone design, which is very convenient for cleaning hair and other debris, and the middle circular hole can be fixed in position with the truncated cone protrusion on the deodorizing core support 1.4; soft plastic is provided on the periphery of the deodorizing core support 1.4, which can seal the gap between the deodorizing core support 1.4 and the plastic panel base 1.2, and the soft plastic adopts secondary injection molding and is a whole with the deodorizing core support 1.4.

[0051] The plastic panel base 1.2 is provided with support edges for cutting and breaking off according to actual needs. The plastic panel base 1.2 is provided with chamfers around its top to match the metal panel chamfers. This chamfer structure allows the metal panel 1.7 of the floor drain to match the plastic panel base 1.2 firmly. After the floor drain is installed, it can achieve a "frameless floor drain" effect from the ground surface. The metal panel 1.7 of the floor drain is 1.21mm higher than the plastic panel base, and the total protruding height is adjusted according to the thickness of the floor tiles.

[0052] like Figure 8 In one embodiment shown, Figure 8 This is a schematic diagram of a different-diameter pipe connection structure of an embodiment of an adjustable secondary drainage floor drain system of the present invention. In this embodiment, the drainage outlet of the horizontal row floor drain heightening sleeve body 2.1 is a horizontal flat tube, and the angle between the flat tube drainage outlet and the vertical outlet is 91.5°. The drainage outlet is tilted downward by 1.5° for easier drainage. The purpose of using a flat tube is to ensure that the minimum height of the floor drain is 50mm, which can be applied to all scenarios with lowered floor heights. The same-layer horizontal row can also be applied to more shiftable scenarios.

[0053] In summary, the present invention provides a flexible and efficient drainage solution through the combination of vertical and horizontal floor drains. The vertical floor drain is connected to the interlayer drainage reserved pipe by raising the main body of the sleeve, ensuring smooth drainage of the interlayer in high floors and complex building environments; while the horizontal floor drain is connected to the drainage system on the same floor through a reducing pipe connection, adapting to different drop plate heights and drainage requirements, and enhancing the adaptability of the drainage system. The design of the secondary drainage protrusion and the guide rib groove effectively avoids the residual water accumulation between the floor drain and the ground gap, ensures the drainage effect, and reduces the adverse effects that may be caused by water accumulation. In addition, the height adjustment function of the overall system improves the flexibility of installation and drainage efficiency, so that the floor drain can be freely installed under different environmental conditions, further enhancing the convenience of use. In terms of deodorization design, the umbrella-shaped deodorization core adopts a folding edge design, which can be automatically closed and opened, preventing odor backflow without affecting the smooth flow of water. When water flows through, the deodorization core automatically shrinks to ensure smooth drainage; when there is no water flow, the folding edge fits tightly to improve the deodorization effect. The fishbone-shaped filter net equipped with the deodorizing core support effectively intercepts hair and debris, making cleaning easier. The full-diameter design and detachable structure further simplify the subsequent cleaning and maintenance process, reduce tedious operations, and improve the user experience. In addition, the present invention uses bevel chamfers and metal panel chamfers in the structural design to ensure the close fit between the metal panel of the floor drain and the plastic base, increase stability and firmness, and avoid the risk of injury caused by sharp angles. The application of soft plastic sealing design and sunken circular groove improves the sealing between the deodorizing core and the base, and further optimizes the deodorizing effect. The overall design not only improves the durability of the system, but also makes the floor drain simple and beautiful in appearance, which meets the aesthetic needs of modern bathrooms and provides a solution that is both practical and beautiful.

[0054] The present invention is not limited to the above-mentioned embodiments. No matter any changes are made in the shape or material composition, any structural design provided by the present invention is a variation of the present invention and should be considered to be within the protection scope of the present invention.
