Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment, and in particular to an odor-proof floor drain core and a floor drain installation structure including the odor-proof floor drain core. Background Technology

[0002] Floor drains are an important interface connecting the drainage pipe system to the indoor floor, and odor-proof drain cores are installed inside the floor drains. As an important component of the drainage system in a residence, the drain core not only drains water normally but also prevents odors or flying insects from the drainage pipes from entering the bathroom through the drain.

[0003] Existing odor-proof drain cores typically achieve a seal between the flap and the drain core seat using magnets, torsion springs, or counterweights. With torsion springs, the spring force weakens quickly after repeated use, making it difficult for the flap to completely close. However, flaps using magnets or counterweights, such as the Chinese patent "A Double-Magnet Sealing Odor-Proof Drain" (CN217949276U), employ two pairs of magnets to control the flap. The first and second magnets at the hinge end of the flap have the same magnetic poles, while the third and fourth magnets at the other end have opposite magnetic poles. Thus, when the flap is opened to a certain angle, the second magnet on one side of the drain core drives the first magnet with the same magnetic poles to close the flap. During closure, the fourth magnet on the outside of the drain core attracts the third magnet on one side of the flap, causing the third magnet to press the flap against the outlet, achieving a seal.

[0004] In the above solution, since the third magnet on the flap is located at the bottom of the flap, dirt can easily adhere to the magnet's attraction part after a period of use, causing the third magnet and the fourth magnet to not be able to be tightly attracted. As a result, the flap and the end of the drain core body cannot be completely closed, thus failing to play the role of preventing odors and insects. Therefore, it needs to be improved. Utility Model Content

[0005] To address the problem in existing technology where the magnetic block at the bottom of the flap is prone to accumulating dirt after a period of use, preventing the flap from fully closing with the drain core, this invention aims to provide an odor-proof drain core. By setting a pressure plate on the side of the flap away from the drain outlet and placing a magnetic block on the pressure plate, and ensuring that the hinge position between the pressure plate and the core, as well as the height of the magnetic block on the pressure plate, are both higher than the hinge between the flap and the core, dirt is prevented from affecting the pressure plate or the magnetic block, thus ensuring that the flap and the drain outlet can be fully closed.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An odor-proof drain core includes a core body and a flap. The core body has a drain outlet on its side, and the flap can close the drain outlet. It also includes a pressure plate located on the side of the flap away from the drain outlet. The top of the flap is hinged to the core body, and the top of the pressure plate is hinged to the core body. The flap can cover the drain outlet, and the bottom of the pressure plate always abuts against the side of the flap away from the drain outlet.

[0008] The present invention is further configured such that: a hinge portion is provided at the top of the flip plate, the flip plate is hinged to the core body through the hinge portion, and the hinge position between the pressure plate and the core body is higher than the hinge portion.

[0009] The present invention is further configured such that a counterweight is provided on the side of the pressure plate away from the flip plate.

[0010] The present invention is further configured such that: the counterweight is a movable magnetic block, and a fixed magnetic block that attracts the movable magnetic block is fixed on the core; the movable magnetic block and the fixed magnetic block are positioned opposite each other and are located on both sides of the pressure plate.

[0011] The present invention is further configured such that the positions of the movable magnetic block and the fixed magnetic block are higher than the drain outlet.

[0012] The present invention is further configured such that the side of the fixed magnetic block facing the pressure plate can be tightly fitted with the pressure plate.

[0013] The present invention is further configured such that: a sliding head is provided at one end of the pressure plate that abuts against the flip plate, the sliding head protrudes from the pressure plate and has a curved surface, and the pressure plate abuts against the flip plate through the sliding head.

[0014] The present invention is further configured such that: the sliding head is hemispherical, and the spherical surface of the sliding head abuts against the flap.

[0015] The present invention is further configured such that the drain outlet of the core extends at an angle and the angle is directed toward the flap.

[0016] This utility model also provides a floor drain installation structure, including a mounting base, a floor drain core installed inside the mounting base, and the aforementioned odor-proof floor drain core. The odor-proof floor drain core includes a mounting pull ring and a mounting clip. The mounting pull ring is located at the top of the core, and the mounting clip is located on the outer wall of the core. The mounting base is provided with a mounting groove, and the mounting clip can engage with the mounting base.

[0017] In summary, the beneficial effects achieved by this utility model are as follows:

[0018] (1) The hinge position of the flap and the core is higher than the drain outlet, and the structure such as the pressure plate and magnetic block that the flap covers on the drain outlet are located above the drain outlet or on the side of the flap away from the drain outlet, so as to avoid the dirt in the sewage flowing out of the drain outlet affecting the pressure plate or magnetic block during long-term use, and ensure that the flap and the drain outlet can be completely closed.

[0019] (2) The weight of the flap and the pressure plate itself, as well as the weight of the movable magnetic block set on the side of the pressure plate away from the flap, can all act on the flap. Furthermore, the drain outlet of the core is not set vertically but extends in an inclined direction toward the flap, so that the flap can cover the drain outlet in its natural state and exert a certain pressure on the drain outlet.

[0020] (3) Since the pressure plate is always in contact with the flap, the weight of the pressure plate and the counterweight can be used to make the flap cover the drain outlet, thus allowing the drain outlet of the core to be tilted away from the pressure plate in the vertical direction. That is, the opening of the drain outlet can be tilted downward, which helps to reduce the impact between the sewage and the sewage pipe wall, so that the sewage can be discharged quickly from the drain outlet.

[0021] (4) When the sewage flowing into the core opens the flap, the larger the opening angle of the flap, the longer the lever arm of the weight of the pressure plate, the flap, and the movable magnetic block acting on the flap, thus ensuring that the flap can quickly close the drain outlet when the impact force of the sewage decreases; while when the flap is already covering the drain outlet, the lever arm of the weight of the pressure plate, the flap, and the movable magnetic block acting on the flap is the smallest, which may not guarantee that the flap and the drain outlet are tightly fitted. However, at this time, the distance between the movable magnetic block and the fixed magnetic block is the closest and the attraction surfaces are aligned with each other, that is, at this time the attraction between the movable magnetic block and the fixed magnetic block is the greatest, thus ensuring that the flap and the drain outlet are tightly fitted.

[0022] (5) A hemispherical sliding head is provided on the side of the pressure plate facing the flip plate. The sliding head abuts against the flip plate, so that the sliding head can slide smoothly on the flip plate when the flip plate is in any angle posture, reducing the friction between the pressure plate and the flip plate, and avoiding scratches that affect the service life.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] As attached Figure 1-5 As shown, an odor-proof drain core includes a core body 4, a flap 5, a pressure plate 6, and a fixing magnetic block 7. The drain core is in a vertical position in the drain.

[0035] The core 4 is a vertically arranged tubular structure, and its interior serves as a sewage flow channel. The core 4 gradually tapers from its upper end to its lower end, and a drain outlet 41 is provided at the lower end of the core 4.

[0036] The drain outlet 41 is semi-circular and located on the side of the core 4. The sewage flowing into the core 4 flows out from the drain outlet 41 and into the sewage pipe.

[0037] The flap 5 is a flat structure, and its shape and size are adapted to the drain outlet 41, so that the flap 5 can completely cover and seal the drain outlet 41, preventing odors or flying insects in the sewage pipe from entering the room through the drain outlet 41.

[0038] The top of the flap 5 is provided with two block-shaped hinge parts 51, and the hinge parts 51 are provided with a rotating shaft that cooperates with the core 4, thereby realizing the hinge connection between the flap 5 and the core 4. When the sewage in the core 4 flows out from the drain outlet 41, the flap 5 is impacted by the sewage and rotates towards the side away from the drain outlet 41.

[0039] The drain outlet 41 of the core 4 is not vertically positioned but rather extends at an angle towards the flap 5, meaning the drain outlet 41 is slightly tilted upwards. Therefore, under its own weight, the flap 5 can cover the drain outlet 41 and exert a certain pressure on it in a natural state.

[0040] A sealing soft rubber layer 52 is provided on the flap 5. The sealing soft rubber layer 52 covers the four edges of the flap 5, thereby reducing the gap between the flap 5 and the drain outlet 41 and improving the sealing performance.

[0041] The pressure plate 6 has a stepped plate structure and is located on the side of the flap 5 away from the drain outlet 41. The top of the pressure plate 6 is hinged to the core 4, and the bottom of the pressure plate 6 abuts against the flap 5, so that when the flap 5 is flipped by the impact of sewage, the pressure plate 6 can also rotate with the flap 5 in the direction away from the drain outlet 41.

[0042] A rectangular movable magnetic block 62 is fixedly installed on the side of the pressure plate 6 away from the flap 5. When the flap 5 drives the pressure plate 6 to rotate, the movable magnetic block 62 can act as a counterweight on the pressure plate 6, and rely on gravity to act on the flap 5, causing the flap 5 to close the drain outlet 41.

[0043] The fixed magnet 7 is fixed to the core 4, and its position is below the hinge point between the pressure plate 6 and the core 4 but above the drain outlet 41. The fixed magnet 7 and the movable magnet 62 are located on opposite sides of the pressure plate 6, their positions are corresponding and their magnetic properties are opposite, allowing them to attract each other. Furthermore, the side of the fixed magnet 7 facing the pressure plate 6 can fit tightly against the pressure plate 6, thereby minimizing the distance between the fixed magnet 7 and the movable magnet 62 and maximizing the attraction between them.

[0044] When the flap 5 covers the drain outlet 41, both the flap 5 and the pressure plate 6 are nearly vertical. At this time, the pressure plate 6 is tightly fitted with the fixed magnet 7, the distance between the fixed magnet 7 and the movable magnet 62 is minimal, and the attraction between them is maximum, ensuring a tight fit between the flap 5 and the drain outlet 41. However, as the sewage inside the core 4 flows out of the drain outlet 41 through the flap 5, the flap 5 and the pressure plate 6 rotate. The distance between the fixed magnet 7 and the movable magnet 62 increases, and the angle difference between the attraction surfaces increases, causing the attraction between them to continuously decrease. But the greater the rotation angle of the flap 5 and the pressure plate 6, the longer the lever arm of the weight of the pressure plate 6, the flap 5, and the movable magnet 62 (acting as a counterweight) acts on the flap 5, thus ensuring that the flap 5 can quickly rotate back to its original position when the impact force of the sewage decreases. During the reset process, the lever arm of the gravity of the pressure plate 6, the flap 5, and the movable magnetic block 62 acting on the flap 5 continuously decreases, but at the same time, the distance between the fixed magnetic block 7 and the movable magnetic block 62 continuously decreases and the angle difference of the attraction surfaces decreases, and the attraction between the two continuously increases, ensuring that the drain outlet 41 is finally sealed.

[0045] Since the hinge positions of the flap 5 and the core 4, the hinge positions of the pressure plate 6 and the core 4, and the heights of the movable magnetic block 62 and the fixed magnetic block 7 are all located above the drain outlet 41, and the pressure plate 6 is located on the side of the flap 5 away from the drain outlet 41, it is possible to prevent dirt in the sewage flowing out of the drain outlet 41 from adhering to the pressure plate 6 or the magnetic block, thereby preventing dirt from affecting the sealing effect of the flap 5 on the drain outlet 41.

[0046] In any position of the flip plate 5, the bottom end of the pressure plate 6 always abuts against the flip plate 5. To reduce friction between the pressure plate 6 and the flip plate 5 and to prevent the pressure plate 6 from causing scratches on the flip plate 5 and affecting its service life, two sliding heads 61 are provided on the side of the pressure plate 6 facing the flip plate 5. The sliding heads 61 protrude from the pressure plate 6 and have a hemispherical surface. The pressure plate 6 abuts against the flip plate 5 through the sliding heads 61, so that the sliding heads 61 can slide smoothly on the flip plate 5 in any angle position.

[0047] Specifically, since the pressure plate 6 always abuts against the flap 5, in some other embodiments, by changing the shape of the pressure plate 6 (e.g., setting the pressure plate 6 to a C-shape) and / or increasing the weight of the pressure plate 6 or the movable magnetic block 62, it is possible to make the flap 5 cover the drain outlet 41 solely by the gravity of the pressure plate 6 and the movable magnetic block 62. In this case, the drain outlet 41 of the core 4 can be tilted in the vertical direction away from the pressure plate 6, that is, the opening of the drain outlet 41 can be tilted downwards. Compared to the slightly tilted upward drain outlet 41 in this embodiment, this effectively enlarges the drain outlet 41 and improves the drainage angle, reducing the impact between sewage and the sewage pipe wall, and facilitating the rapid discharge of sewage from the drain outlet 41.

[0048] Example 2

[0049] This utility model also discloses a floor drain installation structure, including a mounting base 8 and the odor-proof floor drain core in Embodiment 1.

[0050] As attached Figure 1-4 As shown, the odor-proof drain core is also equipped with an installation pull ring 1, a sealing ring retaining ring 2, and an installation block 3.

[0051] The installation pull ring 1 is located at the top of the core 4, with both ends extending into the structure of the core 4. The installation pull ring 1 is for holding by hand, and the odor-proof drain core can be inserted into or pulled out of the mounting base 8 through the installation pull ring 1.

[0052] The sealing ring retainer 2 is used to install and fix the sealing ring, thereby enhancing the sealing effect between the odor-proof drain core and the mounting base 8.

[0053] Mounting blocks 3 are disposed on the outer wall of the core 4, with two mounting blocks 3 located on both sides of the core 4. The mounting blocks 3 are elongated protrusions and are inclined in the horizontal direction.

[0054] Mounting bracket 8 is a common structure in existing floor drains. The drain core is installed in mounting bracket 8, and then the drain core and mounting bracket 8 are installed in the floor drain for normal use. (See attached image) Figure 6 As shown, the central channel of mounting base 8 is used to install and accommodate the odor-proof drain core.

[0055] The mounting base 8 has a mounting groove 81 that matches the mounting block 3. Adjust the position of the core 4 so that the mounting block 3 is aligned with the mounting groove 81, and then insert the odor-proof drain core into the mounting base 8. Then, pull the mounting ring 1 to rotate the odor-proof drain core horizontally, so that the mounting block 3 and the mounting base 8 engage, completing the installation.
