Description

Technical Field

[0001] This utility model relates to the field of drainage pipe system technology, and in particular to a high-flow-rate elongated concealed floor drain. Background Technology

[0002] Traditional concealed strip drains are limited by their elongated shape, so the drain core is often designed as an elongated flip-top. When water flows through the flip-top drain core, the flip-top opens and flips down by the weight of the water to drain the water. However, due to its height limitation, the flip-top drain core cannot achieve a large flow rate by lengthening the design. Therefore, traditional flip-top drain cores often have the problem of low flow rate.

[0003] Chinese Patent Publication No. CN205591321U, Publication Date: September 21, 2016, discloses a utility model entitled "A Flip-Top Drain Core". This application discloses a flip-top drain core including a stainless steel handle, a drain core body, a cover, a main body sealing ring, a cover sealing ring, and a stainless steel shaft. The cover is fixed to the drain core body via the stainless steel shaft. The cover has a gravity cone, an annular asymmetrical groove, and a fixing hole. The stainless steel handle is installed in the handle fixing hole on the drain core body, and the main body sealing ring is engaged in the annular groove of the drain core body. Because of the circular cover, this application cannot achieve an extended design, resulting in a relatively small flow rate. Utility Model Content

[0004] This utility model provides a high-flow-rate, long, invisible floor drain. By setting up a grid-type filter screen and a magnetic drain core, the flow rate is increased, making it easy to clean and odor-proof.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-flow-rate, long, invisible floor drain, comprising a drain panel and a drain body. The drain body contains a grid-type filter screen, the bottom end of which is connected to the drain core via a first limiting step. The drain panel is mounted on the top of the drain body via several limiting supports. The drain core has raised ribs along its inner wall, and a protrusion is provided on the outer ring of the drain core cover, with the protrusion contacting the lower surface of the raised ribs. Limiting supports are provided at the four corners of the drain body, and limiting grooves are provided at the top of the limiting supports near one corner of the drain body. The drain panel is installed in the limiting grooves at the four corners. The grid-type filter screen and magnetic drain core increase the flow rate, facilitating cleaning while also preventing odors.

[0006] Preferably, the drain body is elongated, with a drain seat at the bottom center, and the drain core is housed within the drain seat. The top surface of the drain core and the bottom surface of the drain body's inner cavity are on the same horizontal plane. A drain outlet is located at the bottom of the drain seat. Below the drain body is a circular pipe into which a DN50 pipe can be inserted, ensuring a tight seal. The drain body is a rectangular shell with an open top. The elongated design makes the drain more aesthetically pleasing, and its concealed shape blends seamlessly with the floor, enhancing the overall aesthetics of the interior. Simultaneously, the elongated design increases the drainage area and improves drainage efficiency.

[0007] Preferably, the drain core has several support columns circumferentially arranged at its bottom end. These support columns are bent inward and connected to each other, with several first magnets located at the connection points. The support columns hold the first magnets and provide drainage channels. The first magnet is frustum-shaped with a mounting hole on its upper surface. A second magnet slides within the mounting hole of the first magnet; the mounting hole is cylindrical. The support column design not only provides structural stability but also provides drainage channels, increasing drainage efficiency. The frustum-shaped design of the first magnet and the cylindrical design of the second magnet make the interaction between the magnets more stable, improving the reliability of the drain core cover's opening and closing.

[0008] Preferably, the drain core contains a drain core cover, which is concave with the concave side facing downwards. The upper surface of the drain core cover has several arc-shaped protrusions 7.1 along the axial direction, with the ends of the arc-shaped protrusions 7.1 not exceeding the ribs of the drain body. The outer periphery of the drain core cover has protrusions on a horizontal plane for limiting the position of the drain core cover. The bottom of the drain core cover has several second magnets, which are cylindrical. The concave design and arc-shaped protrusions 7.1 of the drain core cover allow for smoother water flow, reducing water resistance and increasing drainage speed. The protrusions effectively restrict the movement of the drain core cover, ensuring its stability during drainage.

[0009] Preferably, the first and second magnets repel each other, and initially, the protruding upper surface of the drain core cover is in contact with the lower surface of the convex rib of the drain core. When water flows into the drain core, the impact force of the water flow and gravity exert downward pressure on the drain core cover. As the water flow increases, when the water pressure reaches a certain level, the force generated exceeds the repulsive magnetic force on the drain core cover, causing the drain core cover to be pushed open downwards, the protrusion to leave the lower surface of the convex rib, thereby opening the drainage channel. The water flow can then drain into the drain seat through the gap between the support columns of the drain core. This water flow-driven opening and closing mechanism allows the drain core cover to open automatically when the water pressure increases, achieving automatic drainage, reducing the need for manual operation, and improving ease of use.

[0010] Preferably, several support blocks are evenly distributed along the entire length of both sides of the drain body, and the drain panel is placed on the support blocks. This ensures the support strength of the drain panel. The evenly distributed support blocks on both sides of the drain body improve the support strength of the drain panel, ensuring its stability and durability during use.

[0011] Preferably, the length of the drain panel is less than the length of the drain body, the width of the drain panel is less than the width of the drain body, and the thickness is less than or equal to the depth of the limiting groove. The limiting groove is used to restrict the position of the drain panel, ensuring that the drain panel is in the middle of the drain body and that there is a drainage gap between it and the inner wall.

[0012] Preferably, the bottom of the grille-type filter screen has a first limiting step, on which the drain core is placed. The surrounding wall of the grille-type filter screen has several water-passing holes. The design of the first limiting step inside the bottom of the grille-type filter screen and the water-passing holes on the surrounding wall increases the drainage flow while effectively intercepting larger particles of impurities, reducing the risk of pipe blockage.

[0013] Preferably, the bottom outer side of the grid-type filter screen is provided with a second limiting step, which is placed on the inner mounting groove at the top of the drain seat. The design of the second limiting step on the bottom outer side of the grid-type filter screen ensures a tight fit between the filter screen and the drain seat, improving the stability of the structure.

[0014] The beneficial effects of this utility model are as follows: By setting up a grid-type filter screen and a magnetic filter core, this utility model can achieve a large drainage flow and convenient cleaning of foreign objects while ensuring smooth drainage and odor prevention. Because it is an invisible floor drain, it is also aesthetically pleasing and simple after installation. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 As shown, this utility model of a high-flow-rate, long, concealed floor drain mainly consists of two key parts: a drain panel 4 and a drain body 1. The drain body 1, as the core load-bearing component of the entire drain, integrates several important components, including a grid-type filter screen 5 and a magnetic drain core. These components work together to achieve the various functions of the drain. The drain panel 4 covers the top of the drain body 1, serving not only an aesthetic decoration function but also working in conjunction with the drain body 1 to complete the relevant functions during the drainage process.

[0022] like Figure 1 and Figure 2As shown, the drain body 1 has a long, narrow design. Its unique shape allows it to blend seamlessly with the surrounding environment after installation, creating an invisible effect and greatly enhancing the overall aesthetics and functionality of the interior decoration. Structurally, it is a rectangular shell with an open top, providing ample space for the installation and layout of internal components. A drain seat 1.1 is located at its central bottom, serving as the crucial channel for water to drain out. Limiting supports 6.1 are located at the four corners of the drain body 1, with the height of each support slightly less than the depth of the drain body 1. Near the center corner of each of these limiting supports 2, a limiting groove 2.1 is formed. This groove 2.1 is rectangular, created by cutting away a corner of the supporting support 2. It accommodates the four corners of the drain panel 4, providing support while allowing for drainage. This design provides a precise positioning and fixing method for the installation of the drain panel 4, ensuring that the drain panel 4 can be stably installed on the top of the drain body 1, and leaving a suitable drainage gap between it and the inner wall of the drain body 1 to ensure smooth drainage.

[0023] like Figure 1 and Figure 2 As shown, the drain core 6 is elongated to increase drainage flow. The drain core 6 is housed within the drain seat 1.1, with its top surface and the bottom surface of the drain body 1's inner cavity on the same horizontal plane. This design allows water to flow smoothly from the drain body 1's inner cavity into the drain core 6, reducing water resistance and turbulence. The drain seat 1.1 has a drain outlet at its bottom, and a round pipe that can be inserted into a DN50 pipe is connected below the drain body 1. This structural design ensures a tight seal during drainage, preventing odors and pests from the sewer from leaking into the room through the drain outlet.

[0024] like Figure 3As shown, the drain core 6 has several support columns 6.1 circumferentially arranged at its bottom end. In this embodiment, six columns are preferred, with two columns on each of the two long sides and one column on each of the short sides. These support columns 6.1 are bent inward and connected to each other, forming a stable structural frame. The six support columns 6.1 are connected to each other, forming two cross-shaped connection points. Several first magnets 6.2 are provided at the connection points. In this embodiment, two first magnets 6.2 are preferred. One of the main functions of the support columns 6.1 is to place the first magnets 6.2, while cleverly leaving drainage channels. The first magnet 6.2 is designed as a frustum, with a mounting hole on its upper surface and its lower surface fixed to the upper surface of the connection point. The area of ​​the upper surface is smaller than that of the lower surface. The second magnet 7.2 is slidably placed in the mounting hole of the first magnet 6.2, which is cylindrical. This combination of frustum and cylindrical design makes the interaction between the magnets more stable. The inner wall of the drain core 6 has circumferentially circumferentially raised ribs 6.3. The cross-section of the raised ribs 6.3 is trapezoidal, with the hypotenuse at the top and the lower surface on the inner wall, used to limit the position of the drain core cover 7. When water flows into the drain core cover 7, the repulsive magnetic force between the first magnet 6.2 and the second magnet 7.2 interacts with the impact force of the water flow, affecting the opening and closing state of the drain core cover 7. The presence of the support column 6.1 not only enhances the structural stability of the drain core 6, but also increases drainage efficiency by rationally planning the space of the drainage channel, allowing water to be discharged more quickly through the drain core 6.

[0025] like Figure 1 and Figure 4 As shown, the drain core cover 7 is elongated, with a length and width slightly smaller than the drain core 6. It is located inside the drain core 6 and is concave, with the concave side facing downwards. This unique shape design allows water to flow more smoothly through the drain core cover 7, reducing water flow resistance and improving drainage speed. Several arc-shaped protrusions 7.1 are provided axially on the upper surface of the drain core cover 7. The ends of these arc-shaped protrusions 7.1 do not exceed the ribs 6.3 of the drain body 1. When water flows through, the arc-shaped protrusions 7.1 guide the water flow, ensuring it follows a predetermined path and further optimizing drainage smoothness. The drain core cover 7 has a protrusion 7.3 around its periphery. The plane where the protrusion 7.3 is located is a horizontal plane. The design of this protrusion 7.3 is used to limit the position of the drain core cover 7, ensuring the stability of the drain core cover 7 during the drainage process, preventing it from excessive displacement or shaking under the impact of water flow or magnetic force, and ensuring that the drainage channel can be opened and closed normally.

[0026] like Figure 3As shown, the bottom of the drain core cover 7 is provided with several second magnets 7.2, preferably two in this embodiment. The second magnets 7.2 are cylindrical and repel the first magnets 6.2 on the support column 6.1 at the bottom of the drain core 6. In the initial state, the upper surface of the protrusion of the drain core cover 7 is in contact with the lower surface of the rib 6.3 of the drain core 6, and the drain core cover 7 is in a closed state, effectively preventing the emission of sewer odors. When water flows into the drain core 6, the impact force of the water flow and gravity will exert downward pressure on the drain core cover 7. As the water flow increases, when the water pressure reaches a certain level, the force generated is greater than the repulsive magnetic force on the drain core cover 7, and the drain core cover 7 will be pushed down, the protrusion 7.3 will leave the lower surface of the rib 6.3, thereby opening the drainage channel, and the water flow can be discharged into the drain seat 1.1 through the gap between the support columns 6.1 of the drain core 6. This water-driven opening and closing mechanism allows the drain core cover 7 to open automatically when the water pressure increases, achieving automatic drainage, reducing the need for manual operation, and improving ease of use. Moreover, because the repulsive effect between the first magnet 6.2 and the second magnet 7.2 is relatively stable, it ensures that after drainage, as the water pressure decreases, the drain core cover 7 accurately resets under the action of magnetic force, returning to the closed state and continuing to play its role in preventing odors.

[0027] like Figure 2 and Figure 3As shown, the bottom of the grille-type filter screen 5 has a first limiting step 5.2, and the top outer side of the drain core 6 has a limiting protrusion 6.4 along the circumferential direction. The width of the limiting protrusion 6.4 is equal to the width of the first limiting step 5.2. The limiting protrusion 6.4 is placed on the upper surface of the first limiting step 5.2, and the drain core 6 is placed on the first limiting step 5.2. In this way, the drain core 6 and the grille-type filter screen 5 are initially positioned and connected. At the same time, the bottom outer side of the grille-type filter screen 5 has a second limiting step 5.3, which is placed on the inner side of the top of the drain seat 1.1 in the mounting groove 1.1.1. The width of the second limiting step 5.3 is equal to the width of the mounting groove 1.1.1. This design improves the stability of the entire drain structure. During installation, this double limiting step design ensures that the grille-type filter screen 5 is accurately installed in the predetermined position within the drain body 1, and will not loosen or shift during long-term use, ensuring the normal operation of the drain. The grating-style filter screen 5 has several water passage holes 5.1 on its perimeter, which increase the drainage flow rate. Compared to traditional solid filter screens, the grating structure allows more water to pass through simultaneously, improving the drain's drainage efficiency. Simultaneously, the size and distribution of the water passage holes 5.1 are carefully designed to effectively intercept larger particles of impurities, such as hair and sediment, preventing them from entering the drain core 6 and drain pipes, thus reducing the risk of blockages. In daily use, users only need to periodically clean the surface of the grating-style filter screen 5 to maintain good drainage performance. This cleaning method is relatively simple and convenient, requiring no disassembly of the complex internal structure of the drain, greatly reducing maintenance costs and difficulty for users.

[0028] like Figure 1 As shown, the length of the drain panel 4 is less than the length of the drain body 1, the width is less than the width of the drain body 1, and the thickness is less than or equal to the depth of the limiting groove 2.1. This size design allows the drain panel 4 to be accurately installed at the top of the drain body 1, and the limiting groove 2.1 ensures that the drain panel 4 is positioned in the middle of the drain body 1, leaving a suitable drainage gap between it and the inner wall of the drain body 1. Several support blocks 3 are evenly distributed along the entire length of both sides of the drain body 1. The drain panel 4 is placed on the support blocks 3, which ensure the support strength of the drain panel 4. During long-term use, even if people walk on it or heavy objects press on the drain panel 4, the support blocks 3 can evenly distribute the pressure, preventing the drain panel 4 from deforming or being damaged, ensuring the normal use and aesthetics of the drain.

[0029] Work process.

[0030] In daily use, whether it's the large amount of bathwater generated in the bathroom or the water used to wash vegetables in the kitchen, this water flow first comes into contact with the drain panel 4. The drain panel 4 is designed to be both aesthetically pleasing and practical, allowing water to flow smoothly across its surface and guiding it into the main structure of the drain. The water then flows in along the drainage gap between the drain body 1 and the drain panel 4. This gap ensures rapid water flow while effectively intercepting larger particles of impurities, preventing them from entering the drain. The water continues to flow downwards, passing through the grille-type filter screen 5. The design of this filter screen 5 is crucial; its grille structure effectively intercepts larger particles of impurities that could clog the drain, such as hair and food scraps. After these impurities are intercepted, the water is filtered, becoming cleaner, and then continues to flow into the drain core 6. The drain core 6 contains a first magnet 6.2, while the drain core cover 7 contains a second magnet 7.2. The design of these two magnets cleverly utilizes the principle of magnetic repulsion, allowing the drain core cover 7 to close tightly when there is no water flow, effectively preventing odors and pests from flowing back up from the sewer. As the water pressure gradually increases, the impact force of the water flow and gravity work together on the drain core cover 7, ultimately overcoming the repulsive magnetic force between the first magnet 6.2 and the second magnet 7.2. At this point, the drain core cover 7 is pushed open by the water flow, and the protrusion 7.3 moves away from the lower surface of the rib 6.3, allowing the water to flow smoothly through the gap between the support columns 6.1 of the drain core 6 into the drain seat 1.1. The drain seat 1.1 is located at the bottom center of the drain body, with a drain outlet at the bottom, ensuring that the water flows smoothly into and ultimately drains into the sewer. Throughout the drainage process, the user does not need to perform any manual operation; the drain core cover 7 automatically responds to changes in water flow, achieving an automatic drainage function. This automated design not only improves ease of use but also reduces the workload for users in daily maintenance, making drain maintenance simpler and more efficient.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
