However, when faced with drainage needs of large flow and high flow velocity, such as the centralized drainage of washing machines, the drainage capacity of a single channel is insufficient. This can easily lead to water not being able to drain away in time, resulting in water accumulation on the ground or even overflow, causing inconvenience to users. Utility Model Content

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: This embodiment provides a dual-channel diversion drain core, designed to efficiently separate high-flow equipment drainage from conventional floor drainage, and possesses reliable odor-proof and insect-proof functions. For example... Figures 1-6 As shown, it includes the drain body 1 and the inner connecting pipe 2.

[0022] The drain body 1 has an upper opening 11 and two mutually isolated lower outlets 12 and 13. Specifically, the drain body 1 forms the base of the entire drain core and is typically integrally molded from corrosion-resistant materials such as engineering plastics or stainless steel. The overall shape of the drain body 1 can be cup-shaped or frustum-shaped, wider at the top and narrower at the bottom, with an upper opening 11 for receiving water flow. The lower structure of the drain body 1 is the core for diversion, and its interior is divided into at least two physically isolated drainage zones by a partition 16, each drainage zone corresponding to an independent lower outlet. In this embodiment, it is specifically divided into a first lower outlet 12 and a second lower outlet 13. It should be noted that these two lower outlets are spatially independent and do not communicate with each other, laying the foundation for constructing two independent drainage channels.

[0023] The inner connecting pipe 2 is installed inside the drain body 1. Its material can be the same as or similar to the engineering plastic used in the drain body 1 to ensure good fit and durability. The top end of the inner connecting pipe 2 is suitable for connection to a drainage device, which can be a high-flow-rate drainage device (such as a washing machine drain hose). The top end of the inner connecting pipe 2 is tightly connected to the end of the drainage device. An inlet gap 9 for floor drainage is formed between the outer wall of the inner connecting pipe 2 and the inner wall of the upper opening 11. This inlet gap 9 is used to collect and guide surface water (such as shower water, floor cleaning wastewater, etc.) into the drain core. The inner connecting pipe 2 constitutes a first drainage channel connecting its top end to the first lower outlet 12, and the inlet gap 9 constitutes a second drainage channel connecting to the second lower outlet 13.

[0024] In this embodiment, the above-described structural layout forms two independent drainage channels. The first drainage channel is dedicated to high-flow-rate drainage. Its path is as follows: water discharged from high-flow-rate equipment flows through the internal space of the inner connecting pipe 2 and is directly discharged from the first lower outlet 12. Because this channel is a closed pipe, the water flow speed is fast, the flow rate is large, and it does not interfere with the water flow in other areas within the drain core. The second drainage channel is dedicated to ground drainage. Its path is as follows: ground water flows to the drain core, enters the inlet gap 9, and then flows downward along the inner wall of the drain body 1 under the action of gravity, converging at the second lower outlet 13 which is not occupied by the inner connecting pipe 2, and is discharged from there. Since the first and second drainage channels are completely isolated from each other from the inlet to the outlet, efficient diversion drainage is achieved, avoiding the problem of water overflowing from the drain to the ground due to excessive instantaneous flow, or interfering with the normal infiltration of ground water.

[0025] As a preferred embodiment, such as Figure 1As shown, a baffle 8 is connected to the upper end of the inner connecting pipe 2. The baffle 8 is located outside the inner connecting pipe 2 and perpendicular to its axis. The baffle 8 has multiple perforated holes 81 and is detachably connected to the upper opening 11 of the drain body 1, for example, by means of clips or overlaps. The baffle 8 is typically a thin, circular sheet structure. The size of the perforated holes 81 is designed to ensure sufficient water flow area while effectively intercepting larger debris such as hair and paper scraps, preventing them from entering the second drainage channel and causing blockage. A positioning hole is provided in the center of the baffle 8, the diameter of which matches the outer diameter of the inner connecting pipe 2. Preferably, the baffle 8 and the inner connecting pipe 2 are an integral structure or an interference fit connection. Preferably, the baffle 8 overlaps the upper opening 11 of the drain body 1, thereby connecting the inner connecting pipe 2 into the drain body 1. The inner connecting pipe 2 is installed in the middle of the drain body 1, and its upper end is coaxially aligned with the upper opening 11 of the drain body 1. The baffle 8 can be formed by connecting multiple baffles, with a perforation 81 formed between two adjacent baffles. Alternatively, the baffle 8 can also be a flat plate with multiple through holes forming the perforation 81.

[0026] In this embodiment, the baffle 8 serves a dual purpose: firstly, it acts as a filter to protect the downstream pipe; secondly, it supports and positions the inner connecting pipe 2, ensuring its stability and maintaining the shape and dimensions of the inlet gap 9, thereby ensuring smooth drainage from the ground. Its detachable design also greatly facilitates users in cleaning up intercepted debris.

[0027] As a preferred embodiment, such as Figure 3 and Figure 4 As shown, the inner connecting pipe 2 includes a connector 21, a straight pipe section 22, and an inclined pipe section 23. The connector 21 and the inclined pipe section 23 are respectively connected to the upper and lower ends of the straight pipe section 22. A baffle 8 is connected to the straight pipe section 22. The inclined pipe section 23 passes through the first lower outlet 12, and the pipe wall of the inclined pipe section 23 is sealed to the side wall of the first lower outlet 12.

[0028] In this embodiment, the inner connecting pipe 2 can be structurally divided into three parts: upper, middle, and lower. Its top end is a connector 21, the diameter and shape of which are suitable for tight connection with the end of a high-flow-rate drainage device (such as a washing machine drain hose). For example, a reliable anti-detachment and leak-proof connection can be achieved through threads, snap-fits, or elastic sealing rings. The middle part of the inner connecting pipe 2 is a straight pipe section 22, the outer diameter of which is smaller than the inner diameter of the upper opening 11 of the drain body 1. When the inner connecting pipe 2 is coaxially or eccentrically positioned within the drain body 1, a ring-shaped or crescent-shaped inlet gap 9 is naturally formed between its outer wall and the inner wall of the upper opening 11. The lower part of the inner connecting pipe 2 is an inclined pipe section 23, its axis having an angle of deflection relative to the axis of the straight pipe section 22, allowing its end to be precisely aligned and extended into the first lower outlet 12 of the drain body 1.

[0029] As a preferred embodiment, such as Figure 4 As shown, the first lower outlet 12 and the second lower outlet 13 are separated by a partition 16. To ensure a secure and sealed connection between the inner connecting pipe 2 and the first lower outlet 12, a snap-fit ​​plate 24 is provided on the outside of the inclined pipe portion 23. The snap-fit ​​plate 24 is adapted to the first lower outlet 12 and snaps between the partition 16 and the inner wall of the drain body 1, thereby achieving complete isolation between the first drainage channel and the second drainage channel from the inlet to the outlet. A first sealing groove and a first sealing ring 25 are provided on the side of the snap-fit ​​plate 24. The first sealing ring 25 is set in the first sealing groove to seal the snap-fit ​​plate 24 and the first lower outlet 12. During installation, the inclined pipe portion 23 of the inner connecting pipe 2 is pressed into the first lower outlet 12. The snap-fit ​​plate elastically deforms and passes over the edge of the groove before snapping into place, achieving a secure axial fixation. At the same time, the first sealing ring on the snap-fit ​​plate is compressed, filling the fitting gap, thereby achieving a reliable waterproof seal.

[0030] As a preferred embodiment, in order to achieve the functions of deodorization and insect prevention, such as Figure 3 and Figure 4 As shown, a cover assembly 3 is installed at the second lower outlet 13. The cover assembly 3 is closable and connected to the second lower outlet 13, and is equipped with an openable and closable sealing device. When there is surface water flowing through, the cover assembly 3 can be easily opened by the water flow to achieve unobstructed drainage; when there is no water flow, it can automatically and reliably close the second lower outlet 13 to prevent odors and pests in the drainage pipe from entering the room.

[0031] In a preferred embodiment, the cover plate assembly 3 includes a sealing plate 33, a snap fastener 32, and a connecting plate 31. The connecting plate 31 and the sealing plate 33 are respectively connected to both sides of the snap fastener 32. The surface of the connecting plate 31 and the surface of the sealing plate 33 are set at an obtuse angle, or the two can be integrally formed into an L-shaped or V-shaped structure. A mounting cavity 14 is provided on the side of the second lower outlet 13 away from the first lower outlet 12. A rotating shaft 110 is provided on the side wall of the mounting cavity 14. The snap fastener 32 is rotatably connected to the rotating shaft 110. The connecting plate 31 extends into the mounting cavity 14, and the sealing plate 33 extends out of the mounting cavity 14 and is able to seal the second lower outlet 13. The snap fastener 32 has a pivot hole adapted to the rotating shaft 110. By snapping the snap fastener 32 into the mounting cavity 14 and fitting it onto the rotating shaft 110, the entire cover plate assembly 3 can rotate freely around the rotating shaft 110. The size and shape of the sealing plate 33 match the opening of the second lower outlet 13. When closed, it will fit tightly against the inclined plate 17 or sealing edge provided on the drain body 1 around the second lower outlet 13 to achieve a sealing effect.

[0032] In a preferred embodiment, the mounting cavity 14 and the second lower outlet 13 are separated by a guide plate 15. A ramp 17 is connected to the bottom end of the partition plate 16. The ramp 17 is inclined towards the first lower outlet 12, and its bottom end is lower than the bottom end of the guide plate 15. The sealing plate 33 can seal the bottom sides of the ramp 17 and the guide plate 15. In this embodiment, the mounting cavity 14 and the second drainage channel are isolated by the guide plate 15. The upper end of the guide plate 15 is inclined and smoothly connected to the inner wall of the drain body 1. The lower end of the guide plate 15 is vertical, and the inclined plate shape at the upper end and the vertical plate shape at the lower end are smoothly connected. The guide plate 15 guides the water flowing into the second drainage channel, allowing it to flow more smoothly towards and push open the cover assembly 3, preventing water from remaining in the second drainage channel.

[0033] In a preferred embodiment, a magnetic attraction scheme is used to achieve automatic closing of the cover assembly 3. A magnetic cover 4 is provided at the bottom of the mounting cavity 14, and an armature 34 is connected to the connecting plate 31. When the connecting plate 31 is attracted to the magnetic cover 4, the sealing plate 33 seals the second lower outlet 13. The magnetic cover 4 is detachably connected to the bottom of the mounting cavity 14, and one or more permanent magnets are encapsulated inside it. Correspondingly, the armature 34 is disposed inside or on the surface of the connecting plate 31. The armature 34 is a sheet or block made of ferromagnetic material, and its position is directly opposite the magnetic cover 4 below. When surface water flows into the second drainage channel, the weight and impact force of the water flow act on the sealing plate 33, and the torque generated is greater than the closing torque generated by the magnetic attraction force of the magnetic cover 4 on the armature 34, thereby pushing the cover assembly 3 to flip upward around the pivot 110 and open, allowing the water to drain smoothly. When the water flow stops or decreases, the thrust of the water flow is insufficient to overcome the magnetic attraction. At this time, the magnetic attraction of the magnet cover 4 to the armature 34 becomes dominant, attracting the connecting plate 31 to move downward, thereby driving the sealing plate 33 to rotate around the rotating shaft 110 to the closed position, thus achieving reliable automatic sealing.

[0034] Alternatively, a counterweight can be installed on the connecting plate 31. Under the action of the counterweight, the sealing plate 33 naturally seals at the second lower outlet 13. This counterweight is typically made of a high-density metal material and can be firmly attached to the connecting plate 31 by methods such as injection molding, screw fixing, or adhesive bonding. The mass and installation position of the counterweight are precisely designed, and it is installed on the side away from the rotating shaft, so that its center of gravity generates a significant lever arm relative to the rotating shaft. Its working principle is as follows: when no water flows through the second drainage channel, the counterweight's own weight generates a closing torque around the rotating shaft. This torque is sufficient to drive the entire cover assembly to automatically rotate to the closed position, causing the sealing plate 33 to tightly seal the second lower outlet 13. When surface water flows down, the opening torque generated by the pressure of the water flow acting on the sealing plate 33 is greater than the closing torque generated by the counterweight, thus pushing the cover open to achieve drainage. Once the water flow stops, the opening torque disappears, the closing torque becomes dominant again, and the cover automatically resets and closes. Compared to magnetic attraction methods, the gravity-based method in this embodiment has a simpler structure, eliminates the need for magnetic materials, and thus reduces manufacturing costs. Furthermore, its performance is unaffected by ferromagnetic impurities in the environment and will not fail due to demagnetization of the magnet caused by prolonged use or high-temperature environments, thereby improving long-term reliability and lifespan.

[0035] In a preferred embodiment, the dual-channel diversion drain core of this embodiment also includes a wide-mouth component 5. The wide-mouth component 5 is an independent annular part, and its overall shape is usually a conical or stepped ring that is wider at the top and narrower at the bottom. The material is usually the same as that of the drain body 1. The wide-mouth component 5 is coaxially installed on the outside of the drain body 1. A connecting ring 18 is formed radially extending from the upper outer edge of the drain body 1. A first connecting platform 51 is provided on the wide-mouth component 5, and the connecting ring 18 can be embedded in the wide-mouth component 5. A second sealing ring 19 is connected to the lower side of the connecting ring 18 of the drain body 1. The second sealing ring 19 can abut against the first connecting platform 51. During installation, the drain body 1 is placed into the wide-mouth component 5 from above, and the second sealing ring 19 abuts against the first connecting platform 51, achieving reliable axial positioning. This sealing structure can prevent water from leaking from the joint. A pull ring 7 is connected to the drain body 1 to facilitate the installation or removal of the drain body 1 by pulling the pull ring 7.

[0036] In a preferred embodiment, a second overlapping platform 52 is provided on the upper side of the first overlapping platform 51 of the wide-mouth component 5, and the diameter of the second overlapping platform 52 is larger than the diameter of the first overlapping platform 51. The second overlapping platform 52 is set at the same height as the overlapping ring 18 of the drain body 1, and the baffle 8 can be installed on both the second overlapping platform 52 and the overlapping ring 18 simultaneously. A retaining edge 53 is also provided on the top of the wide-mouth component 5, and the retaining edge 53 is connected to the outer ring of the second overlapping platform 52, and the outer side of the retaining edge 53 is provided with external threads. Preferably, a third sealing ring 52 is installed on the bottom side of the second overlapping platform 52 of the wide-mouth component 5 to achieve a seal between the wide-mouth component 5 and the connecting component during installation.

[0037] During installation, if the inner diameter of the pre-drain hole in the ground matches the outer diameter of the drain body 1, the drain body 1 can be installed directly. If the inner diameter of the pre-drain hole is larger, the wide-mouth fitting 5 should be installed and fixed in the pre-drain hole first, and then the drain body 1 should be installed into the wide-mouth fitting 5. In this way, a set of standard-sized drain core products can flexibly adapt to various sizes of drain holes by matching one or more wide-mouth fittings with different outer diameters, improving the product's versatility and ease of installation.

[0038] In summary, this embodiment constructs independent first and second drainage channels through the structural combination of the drain body 1 and the inner connecting pipe 2. The baffle 8 with hollowed-out holes realizes filtration and positioning, and the magnetic cover assembly 3 realizes automatic odor prevention of the ground drainage channel. The structure is reasonable and the function is complete.

[0039] In this embodiment, by constructing independent first and second drainage channels, the drainage from high-flow equipment and the ground drainage are separated. High-flow wastewater can be discharged directly and quickly without affecting the normal infiltration of ground water, fundamentally solving the problem of ground water accumulation and overflow caused by interference from high-flow drainage, and significantly improving drainage efficiency. By setting an automatically opening and closing cover assembly at the outlet of the ground drainage channel, the drainage pipe is effectively sealed when there is no water, reliably preventing sewer odors and insects from entering the room, thus improving the hygiene level of the living environment. By setting a detachable filter baffle, not only can the internal connecting pipe be effectively fixed, but debris can also be intercepted, making cleaning and maintenance convenient. By adding an optional wide-mouth fitting, the drain core can be adapted to installation bases of different diameters, improving the product's versatility and ease of installation.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
