Technical Field
[0001] This utility model relates to the field of bathroom equipment technology, specifically a drainage floor drain with spiral flow guiding function. Background Technology
[0002] Floor drains, as an important component of drainage systems, are widely used in homes and public places. Their main function is to drain wastewater from the ground while preventing odors, insects, and debris from entering the drainage pipes. However, existing floor drains generally suffer from some problems that urgently need to be addressed, affecting the user experience and the overall performance of the drains.
[0003] First, existing floor drains often lack innovation in appearance design, resulting in severe homogenization. Most floor drains use a design with several regular or irregular drainage holes on a flat surface. While this design offers limited functionality, it leads to a uniform appearance of floor drains on the market, failing to meet the aesthetic and personalized needs of modern homes and buildings. Consumers find it difficult to find products with unique design and visual appeal when choosing a floor drain.
[0004] Secondly, existing floor drain panels have significant shortcomings in terms of debris isolation and cleaning / maintenance. Since the main function of the panel is to isolate larger debris to prevent it from entering the drain pipe and causing blockages, debris such as hair, sediment, and food scraps carried by the water flow often remain directly on the panel's surface. This accumulation not only severely affects the overall aesthetics of the floor drain, giving it an unclean appearance, but also easily breeds bacteria and produces odors in a damp environment. This necessitates frequent (even daily) cleaning of the floor drain panel by users, increasing the burden of daily maintenance and greatly reducing ease of use.
[0005] Furthermore, existing floor drains suffer from poor drainage efficiency and clogging resistance. The traditional panel design has a relatively small effective filtration and drainage area. When a large flow of water carrying small debris (such as hair and particles) passes through these limited holes, the debris easily accumulates, causing the drain panel to become clogged. Once clogged, water cannot drain away promptly, affecting usability and potentially creating safety hazards such as slippery surfaces. Therefore, further improvements are necessary. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a floor drain with a spiral flow guiding function that is more compact in structure, more aesthetically pleasing in appearance, easier to clean and maintain, and has strong drainage efficiency and anti-clogging ability.
[0007] The purpose of this utility model is achieved through the following means: a drainage floor drain with spiral flow guiding function, which includes a rectangular body, an installation cavity is provided in the upper part of the rectangular body, and a connecting pipe is provided at the bottom of the installation cavity; Isolation platforms are provided at one pair of opposite diagonal points of the mounting cavity, and drainage channels are provided at the other pair of opposite diagonal points; The top of the mounting cavity is covered with a panel, the bottom of which rests on an isolation platform. An air-avoidance area is provided on the panel at the diagonal corner corresponding to the location of the drainage channel.
[0008] Furthermore: the isolation platform is arranged along two adjacent sides facing opposite corners, and the distance between the top of the isolation platform and the top of the rectangular main body is less than or equal to the thickness of the panel.
[0009] Furthermore, the isolation platform is a step that extends outward along the side wall of the mounting cavity.
[0010] Furthermore, the drainage groove is an arc-shaped inclined surface that is set inside the mounting cavity and tilted towards the center of the mounting cavity.
[0011] Furthermore: the aforementioned clearance area is a rounded corner set at the diagonal of the panel, and a drainage area is formed between the rounded corner and the drainage channel.
[0012] Furthermore, the connecting pipe is a cone shape that is wider at the top and narrower at the bottom, and a filter cup is also installed inside the mounting cavity.
[0013] Furthermore: the filter cup includes a cup body and a docking ring located at its top. Correspondingly, a connecting seat is provided inside the docking tube, and the filter cup is installed in the connecting seat through the docking ring.
[0014] Furthermore, the top of the docking ring also has symmetrically outwardly extending support feet, the bottom of the support feet covers the mounting cavity, and the top of the support feet is provided with a limiting seat that is locked at the corner of the mounting cavity.
[0015] Furthermore, an upward arc extending from the inside of the cup body is provided with a flow guide platform, which is connected to the support foot by an arc transition. The arc transition connection structure between the flow guide platform and the support foot is used to guide the water flow to form a spiral vortex.
[0016] Furthermore, the top of the panel is recessed and has an inlay area, in which a decorative panel is installed.
[0017] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.
[0018] This utility model adopts a design where the panel is essentially a single piece, and water flow is mainly through a recessed area for drainage, rather than through traditional panel openings. This design makes the panel surface smoother and more complete, greatly improving the overall appearance of the floor drain and breaking away from the monotonous perforated panel design of traditional floor drains.
[0019] Because foreign objects do not accumulate directly on the panel surface, but instead flow with the water through the air-retaining area directly into the filter cup below the panel for filtration, this effectively prevents hair, sand, and other debris from remaining on the panel surface. This fundamentally ensures the cleanliness and hygiene of the panel, eliminating the need for frequent cleaning and significantly reducing the user's daily maintenance burden. It also solves the pain points of existing technologies where unsightly foreign object accumulation requires daily cleaning.
[0020] 4. The utility model panel features a recessed mounting area at the top, within which a decorative panel is installed. This unique design endows the drain with exceptional customizability and aesthetic value. Users can select a decorative panel that matches the bathroom floor tiles in frame or material, allowing the drain's appearance to seamlessly integrate with its surroundings, achieving a more beautiful, clean, and unified visual effect. This breaks through the limitations of traditional drains in terms of appearance, providing users with greater design freedom and satisfying modern architecture's pursuit of detail and overall aesthetics.
[0021] 5. This invention not only guides water flow through the clearance zone and diversion channel, but more importantly, it uses a guide platform extending upwards in an arc within the filter cup, and an arc-shaped transition connection between the guide platform and the support foot, to guide the water flow into a spiral vortex. This spiral guide design generates strong rotational kinetic energy when the water enters the filter cup, effectively flushing and removing debris adhering to the filter cup wall, thus achieving efficient drainage and strong self-cleaning ability, significantly reducing the risk of filter cup clogging. Compared with existing leak holes and filter screens that are easily clogged by debris, the spiral guide function of this invention greatly improves the anti-clogging performance and continuous drainage efficiency of the floor drain.

Detailed Implementation
[0030] The present invention will be further described in detail below with reference to the accompanying drawings. A drainage floor drain with spiral flow guiding function includes a rectangular body 1, an installation cavity 2 recessed at the top of the rectangular body 1, and a connecting pipe 3 at the bottom of the installation cavity 2; An isolation platform 4 is provided at one pair of opposite diagonal positions of the mounting cavity 2, and a drainage channel 5 is provided at the other pair of opposite diagonal positions; The top of the mounting cavity 2 is covered with a panel 6, the bottom of the panel 6 is supported on the isolation platform 4, and an air-avoidance area 7 is provided on the panel 6 at the diagonal position corresponding to the drainage channel 5.
[0031] In this embodiment: when water needs to be discharged, it first enters the mounting cavity 2 from the clearance area 7 on the panel 6. The clearance area 7 is located at a pair of corners of the panel 6, corresponding to the drainage channel 5 in the mounting cavity 2 below. After passing through the clearance area 7, the water is guided into the mounting cavity 2 by the drainage channel 5. The panel 6 is supported by the isolation platform 4 set in the mounting cavity 2 at its bottom, thereby isolating the mounting cavity 2 from the external environment and serving as the main supporting and decorative component. Finally, the water in the drain will be discharged through the connecting pipe 3 at the bottom of the mounting cavity 2.
[0032] In this invention, the panel 6 features only a void area 7 instead of being covered with numerous drainage holes, resulting in a largely intact panel surface and significantly enhancing the overall aesthetic appeal of the drain. Furthermore, the combination of the void area 7 and the drainage channel 5 prevents large foreign objects from directly covering and clogging the densely packed drainage holes found on traditional panels.
[0033] In one embodiment: the isolation platform 4 is arranged along two adjacent sides facing opposite corners, and the distance between the top of the isolation platform 4 and the top of the rectangular body 1 is less than or equal to the thickness of the panel 6.
[0034] In this embodiment, the isolation platform 4 is not a point support, but rather a step formed by extending along two adjacent sides connected at opposite diagonals in the mounting cavity 2, i.e., right-angled sides. Simultaneously, the distance between its top and the top of the rectangular body 1, i.e., the lower surface of the panel 6, is precisely defined to be less than or equal to the thickness of the panel 6. This ensures that the panel 6, after installation, is flush with or slightly below the floor drain body, preventing the panel from bulging.
[0035] The isolation platform 4 extends along the side rather than being a point support, providing a wider and more stable bearing surface for the panel 6 and improving the installation stability of the panel.
[0036] In one embodiment: the isolation platform 4 is a step that extends outward along the side wall of the mounting cavity 2.
[0037] The isolation platform 4 is integrally formed with the side wall of the mounting cavity 2, which improves the integrity and strength of the main structure of the floor drain, reduces the number of parts, and facilitates manufacturing. At the same time, this forming method provides precise load-bearing positioning for the panel 6.
[0038] In one embodiment, the drainage channel 5 is an arc-shaped inclined surface disposed within the mounting cavity 2 and tilted towards the center of the mounting cavity 2. After the water flows through the clearance area 7 into the drainage channel 5, the arc-shaped inclined surface of the drainage channel 5 guides the water flow towards the center of the mounting cavity 2. This inclined and arc shape helps the water flow smoothly and may initially form a guiding effect to some extent.
[0039] In this embodiment, the arc-shaped bevel design avoids the obstruction of water flow by right angles or acute angles, ensuring that water can enter the installation cavity 2 quickly and smoothly, creating conditions for subsequent spiral flow guidance.
[0040] In one embodiment: the clearance zone 7 is a rounded corner set at the opposite corner of the panel 6, and a drainage zone 8 is formed between the rounded corner and the drainage channel 5.
[0041] The clearance zone 7 is a rounded corner at the diagonal of panel 6. This corner shape, together with the drainage channel 5 below, forms a drainage zone 8. Water flows through this drainage zone 8 into the installation cavity 2. The rounded corner design ensures a sufficient drainage outlet area, allowing large flow rates of water to enter quickly. At the same time, this open, rounded corner design is less prone to blockage by large debris compared to small holes, thus improving the initial anti-clogging capability of the floor drain.
[0042] In one embodiment, the connecting pipe 3 is a cone shape that is larger at the top and smaller at the bottom, and a filter cup is also installed in the mounting cavity 2.
[0043] In this embodiment, the conical design of the connecting pipe 3, which is wider at the top and narrower at the bottom, helps to guide the water flow smoothly from the installation cavity 2 and accelerate its discharge, reducing water flow resistance. Secondly, a filter cup is installed inside the installation cavity 2. This filter cup is the core component inside the floor drain for intercepting and filtering debris, ensuring that debris does not enter deeper drainage pipes.
[0044] In addition, the conical connecting pipe 3 helps to create a siphon effect, accelerates water flow and improves drainage efficiency.
[0045] In one embodiment: the filter cup includes a cup body 9 and a docking ring 10 located at its top. Correspondingly, a connecting seat 11 is provided in the connecting tube 3, and the filter cup is installed in the connecting seat 11 through the docking ring 10.
[0046] In this embodiment, the filter cup consists of a cup body 9 with filter holes and a top mating ring 10. A connecting seat 11 is provided inside the connecting tube 3. The filter cup is connected to the connecting seat 11 through the mating ring 10 at its top and is installed inside the connecting tube 3.
[0047] Therefore, the mating installation of the docking ring 10 and the connecting seat 11 ensures the stable placement of the filter cup in the installation cavity 2, preventing shaking or accidental detachment.
[0048] Meanwhile, this installation structure is usually designed to snap or screw on, making it easy for users to remove the filter cup by hand or with simple tools for cleaning and maintenance.
[0049] In one embodiment: the top of the docking ring 10 also has a support foot 12 extending symmetrically outward, the bottom of the support foot 12 covers the mounting cavity 2, and the top of the support foot 12 is provided with a limiting seat 13 that is locked at the corner of the mounting cavity 2.
[0050] In this embodiment, support feet 12 extend symmetrically outward from the top of the docking ring 10. The bottoms of these support feet 12 are supported on the inner wall of the mounting cavity 2, and they extend upward, with limiting seats 13 at their top ends. When the filter cup is installed in place, these limiting seats 13 precisely engage at the corners of the mounting cavity 2, thereby providing multi-point limiting and support for the filter cup. This prevents the filter cup from rotating or shifting due to water flow impact or during use.
[0051] In one embodiment: a flow guide platform 14 is provided in the cup body 9 extending upward in an arc. The flow guide platform 14 is connected to the support foot 12 in an arc transition. The arc transition connection structure between the flow guide platform 14 and the support foot 12 is used to guide the water flow to form a spiral vortex.
[0052] In this embodiment, an upwardly extending flow guide platform 14 is designed inside the body 9 of the filter cup. More importantly, this flow guide platform 14 and the support leg 12 employ a unique structure with a rounded transition connection. When water enters the filter cup, it flows along the continuous arc surface formed by the flow guide platform 14 and the support leg 12. This carefully designed curved surface structure cleverly converts the downward kinetic energy of the water flow into tangential rotational kinetic energy, thereby actively guiding the water flow to form a strong spiral vortex within the filter cup.
[0053] The resulting spiral vortex has a powerful scouring force, which can effectively remove hair, mud and other debris attached to the inner wall of the filter cup and the guide platform 14, achieving a self-cleaning effect of the filter cup, significantly reducing the probability of clogging and extending the cleaning cycle.
[0054] At the same time, the vortex can cause debris to rotate inside the filter cup and concentrate at the bottom or in a specific area, improving filtration efficiency and preventing debris from accumulating around the filter holes and causing local blockage.
[0055] In addition, the arc transition connection between the flow guide platform 14 and the support foot 12 achieves a perfect integration of structure and function, improving component strength and manufacturing efficiency.
[0056] In one embodiment: the top of the panel 6 is recessed with an inlay area 15, and a decorative panel 16 is installed in the inlay area 15.
[0057] In this embodiment, the decorative panel 16 can be a ceramic tile of the same material and pattern as the surrounding floor tiles, or it can be other decorative materials such as metal, glass, or wood. This allows the floor drain to blend seamlessly with the bathroom or kitchen floor decoration style, achieving the effect of an invisible or personalized floor drain.
[0058] Therefore, the decorative panel 16 can be integrated with the bathroom floor tiles, making the drain more aesthetically pleasing and neat, breaking through the monotony of traditional drain panels and greatly enhancing the overall decorative effect.
[0059] The specific working principle is as follows: When water needs to be drained from the ground, the water will first converge in the drain area. Since the panel 6 of this invention is mostly fully covered, the water will enter the drain through the pre-set clearance area 7 on the panel 6. The clearance area 7 is usually located at a diagonal corner of the panel 6, precisely corresponding to the drainage channel 5 set in the mounting cavity 2 below. The arc-shaped sloping surface design of the drainage channel 5 can guide the water to flow smoothly towards the center of the mounting cavity 2.
[0060] After initial guidance by the flow channel 5, the water enters the central area of the mounting cavity 2 and further flows into the filter cup installed within the mounting cavity 2. The filter cup is the core component of this invention for achieving efficient filtration and spiral flow guidance.
[0061] Inside the filter cup, the water flow encounters a carefully designed guide platform 14 and an arc-shaped transition connection structure between it and the support feet 12. It is this unique structure that converts the energy of the falling water flow into tangential kinetic energy, actively guiding the water flow to form a strong spiral vortex inside the filter cup.
[0062] This spiral vortex plays several key roles within the filter cup: High-efficiency filtration: The vortex drives the water flow to rotate at high speed inside the filter cup, making it easier for impurities in the water, such as hair and sediment, to be washed into the filter holes of the filter cup due to centrifugal force or driven by the vortex, and effectively intercepted, preventing them from entering the drain pipe.
[0063] Powerful self-cleaning ability: The scouring force of the vortex can effectively remove debris adhering to the inner wall of the filter cup and the guide platform 14, significantly reducing debris accumulation, thereby reducing the risk of filter cup clogging and extending the cycle of cleaning the filter cup for users.
[0064] The filtered water, driven by the vortex, flows through the bottom of the filter cup and converges into the connecting pipe 3. The connecting pipe 3 adopts a conical design that is wider at the top and narrower at the bottom, which helps to further accelerate the water flow and ultimately discharge the treated water smoothly into the main drain pipe.
[0065] Furthermore, this utility model has also been optimized in terms of installation and maintenance: Panel 6 is securely installed by being supported on the isolation platform 4 within the mounting cavity 2.
[0066] The filter cup is installed with the connecting seat 11 inside the connecting pipe 3 via the docking ring 10 at its top, and is secured at the corner of the mounting cavity 2 by the symmetrically extending outward support feet 12 and the limiting seat 13 at its top, ensuring that the filter cup is stably supported and precisely positioned at multiple points inside, while also allowing users to easily disassemble the filter cup for cleaning and maintenance.
[0067] The mounting area 15 at the top of panel 6 can be fitted with decorative panel 16, which enables a high degree of customization of the appearance of the floor drain, allowing it to blend in with the surrounding environment and greatly improving the aesthetics of the floor drain and the overall decoration effect.
[0068] In summary, this utility model of floor drain comprehensively improves the drainage efficiency, anti-clogging ability, self-cleaning performance, ease of cleaning and maintenance, and aesthetics of the floor drain through the clearance area on the panel, the flow channel, and especially the spiral vortex structure formed by the flow guide platform and support feet inside the filter cup, as well as convenient installation and maintenance and highly customizable appearance design. It provides a new drainage solution with excellent performance and better user experience, and therefore can be widely promoted.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
