Description

Technical Field

[0001] This utility model belongs to the field of drainage floor drain technology, and relates to a same-layer leak-proof and odor-proof drainage floor drain. Background Technology

[0002] In building floor drainage systems, floor drains, as key components connecting drainage pipes to the indoor floor, directly affect the comfort and hygiene of the living environment through their leak-proof and odor-proof performance. Existing floor drains for floor drainage systems generally suffer from the following problems: First, their odor-proof structures are often simplistic, employing only a single water seal or check valve. Water seals are prone to drying out and failing due to prolonged disuse, while check valves are easily blocked by hair and debris, leading to inadequate sealing and unstable odor-proofing effects. Second, they lack adaptability; a single floor drain typically only matches a specific type of drainage pipe. When the pipe specifications need to be changed, the entire floor drain must be replaced, increasing construction costs and inconvenience.

[0003] To address the aforementioned issues, there is an urgent need for a floor drain with multiple odor-proof structures, strong adaptability, and excellent sealing and leak-proof performance, in order to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a same-floor leak-proof and odor-proof drainage floor drain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A leak-proof and odor-proof floor drain with a single-layer design includes a drain body, which comprises a drain trough, a magnetic gravity odor-proof drain core, and a water-sealed odor-proof container. The magnetic gravity odor-proof drain core is fixedly installed at the middle of the bottom of the drain trough, and its bottom is mounted on the water-sealed odor-proof container. The drain trough includes a trough body and a cover plate. The interior of the trough body has a fixing hole, and the cover plate is fastened to the top of the trough body. The edge of the cover plate has a drain hole. The magnetic gravity odor-proof drain core includes a closing plate, a counterweight, and a drain core shell. The top of the drain core shell is installed in the fixing hole, and a fixing ring is threaded onto the exterior of the drain core shell.

The closing plate is movably hinged to the drain interface, and the counterweight is fixedly installed on one side of the closing plate. A magnetic plate is provided on the contact surface between the closing plate and the drain interface.

[0006] In the above-mentioned same-layer leak-proof and odor-proof drainage floor drain, the water seal structure odor-proof pot includes a pot body, a drain pipe and a sealing cap. The drain pipe is fixedly installed on one side of the pot body, and the sealing cap is installed on the top of the pot body. The sealing cap is provided with an installation hole.

[0007] In the above-mentioned same-layer leak-proof and odor-proof drainage floor drain, the inner wall of the mounting hole is provided with a detachable docking ring, and the outer wall of the docking ring is provided with a double-layer sealing element.

[0008] In the above-mentioned same-layer leak-proof and odor-proof drainage floor drain, the inside of the pot body is provided with a water seal groove, the bottom of the water seal groove is fixedly connected to the bottom surface of the pot body, and the top of the water seal groove is open.

[0009] In the above-mentioned same-layer leak-proof and odor-proof drainage floor drain, the sealing cover is provided with an installation pipe inside, the top of the installation pipe extends to the installation hole, and the bottom of the installation pipe extends into the water seal groove.

[0010] In the above-mentioned same-layer leak-proof and odor-proof floor drain, one side of the drain pipe is connected to the side wall of the kettle body, and a backflow prevention and odor-proof floor drain core is provided at the end of the drain pipe away from the kettle body.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-6As shown, a same-floor leak-proof and odor-proof floor drain includes a floor drain body 1. The floor drain body 1 includes a drainage channel 2, a magnetic gravity odor-proof drain core 3, and a water seal structure odor-proof container 4. The magnetic gravity odor-proof drain core 3 is fixedly installed at the middle position of the bottom of the drainage channel 2, and the bottom of the magnetic gravity odor-proof drain core 3 is installed on the water seal structure odor-proof container 4. The drainage channel 2 includes a channel body 5 and a cover plate 6. The inside of the channel body 5 is provided with fixing holes. The cover plate 6 is fastened to the top of the channel body 5, and the edge of the cover plate 6 is provided with drainage holes. The odor-proof drain core 3 includes a closing plate 7, a counterweight 8, and a drain core housing 9. The top of the drain core housing 9 is installed in a fixing hole. A fixing ring 10 is threaded onto the outside of the drain core housing 9. A sealing ring is fixedly installed on the upper surface of the fixing ring 10. The drain core housing 9 is a hollow structure with an open top and a drain interface 11 at its lower end. The closing plate 7 is movably hinged to the drain interface 11. The counterweight 8 is fixedly installed on one side of the closing plate 7. A magnetic piece 12 is provided on the contact surface between the closing plate 7 and the drain interface 11.

[0027] Furthermore, the water-sealed odor-proof kettle 4 includes a kettle body 13, a drain pipe 14, and a sealing cap 15. The drain pipe 14 is fixedly installed on one side of the kettle body 13, and the sealing cap 15 is installed on the top of the kettle body 13. The sealing cap 15 is provided with an installation hole 16.

[0028] In this embodiment, the water-sealed odor-proof bottle 4 and the magnetic gravity odor-proof drain core 3 work together to achieve the odor-proof function of the drain, effectively solving the problem of traditional drains easily emitting odors.

[0029] Furthermore, the inner wall of the mounting hole 16 is provided with a detachable docking ring 17, and the outer wall of the docking ring 17 is provided with a double-layer sealing element.

[0030] Furthermore, a water seal groove 18 is provided inside the kettle body 13. The bottom of the water seal groove 18 is fixedly connected to the bottom surface of the kettle body 13, and the top of the water seal groove 18 is open.

[0031] In this embodiment, the water seal groove 18 can further enhance the odor-proof effect of the water seal structure odor-proof pot 4. When water flows into the pot body 13, a water seal of a certain height will be formed in the water seal groove 18, which effectively prevents odor from overflowing from the drain pipe 14 in the reverse direction. Together with the magnetic gravity odor-proof floor drain core 3, it forms a double odor-proof barrier, which greatly improves the overall odor-proof performance of the floor drain and provides a more reliable guarantee for the indoor environment.

[0032] Furthermore, the sealing cover 15 is provided with an installation tube 19 inside, the top of the installation tube 19 extends to the installation hole 16, and the bottom of the installation tube 19 extends into the water seal groove 18.

[0033] In this embodiment, the bottom of the installation pipe 19 extends into the water seal groove 18, so that the water flowing in from above can accurately enter the water seal groove 18 and form an effective water seal in the water seal groove 18.

[0034] Furthermore, one side of the drain pipe 14 is connected to the side wall of the kettle body 13, and a backflow prevention and odor prevention drain core 26 is provided at the end of the drain pipe 14 away from the kettle body 13.

[0035] In this embodiment, the backflow prevention and odor-proof floor drain core 26 installed at one end of the drain pipe 14 can automatically open when draining and automatically close after draining to prevent odors from entering the room from the drain pipe 14.

[0036] Furthermore, the backflow prevention and odor prevention drain core 26 includes a sealing plate 20 and a sealing pipe 21. The sealing pipe 21 is fixedly installed inside the drain pipe 14, and the sealing plate 20 is installed obliquely at the water outlet end of the sealing pipe 21. The top of the sealing plate 20 is movably hinged to the sealing pipe 21.

[0037] In this embodiment, the sealing plate 20 can be flexibly opened and closed under the action of water flow. When water flows through, the water flow impacts the sealing plate 20, causing it to rotate around the hinge point and open, allowing the water to flow out smoothly. When the water flow stops, the sealing plate 20 automatically closes under its own weight and tilt angle, preventing the odor from flowing back.

[0038] Furthermore, a counterweight 22 is fixedly installed on the outer side of the sealing plate 20.

[0039] In this embodiment, the installation of the counterweight 22 can increase the weight of the sealing plate 20, enabling it to close more quickly and tightly at the outlet end of the sealing pipe 21 when there is no water flow, further improving the sealing performance of the backflow prevention and odor prevention drain core 26.

[0040] Furthermore, a connecting pipe 23 is installed on the outside of the drain core housing 9, and a first sealing ring 24 is installed on the outside of the connecting pipe 23. The connecting pipe 23 is installed inside the docking ring 17 through the first sealing ring 24.

[0041] In this embodiment, the first sealing ring 24 enhances the sealing between the connecting pipe 23 and the docking ring 17, preventing water from leaking out from the connection and ensuring the overall leak-proof effect of the floor drain.

[0042] Furthermore, a second sealing ring 25 is installed on the outside of the drain core housing 9.

[0043] In this embodiment, another matching style of drainage floor drain is provided, which can be matched with floor drains of different specifications by changing the sealing ring.

[0044] The working principle of this utility model is as follows: When this utility model is in use, after the water flows into the drainage channel 2 through the drainage hole at the edge of the cover plate 6, it flows along the channel body 5 to the magnetic gravity anti-odor drain core 3. At this time, the water flow impacts the closing plate 7. Since a counterweight 8 is fixedly installed on one side of the closing plate 7, and a magnetic plate 12 is provided on the contact surface between the closing plate 7 and the drainage interface 11, the closing plate 7 rotates and opens around the hinge point under the action of the water flow impact force, and the water flows through the drainage interface 11 into the water seal structure anti-odor pot 4. Part of the water flowing into the water seal structure anti-odor pot 4 flows into the water seal groove 18 through the installation pipe 19, forming a water seal of a certain height in the water seal groove 18, effectively preventing odor from overflowing back from the drain pipe 14; the other part of the water flows into the pot body 13. When the water flow continues to flow to the drain pipe 14, the water flow impacts the sealing plate 20 in the anti-odor drain core 26, and the sealing plate 20 rotates and opens around the hinge point, and the water flows smoothly out through the drain pipe 14.

[0045] When the water flow stops, the closing plate 7 in the magnetic gravity anti-odor drain core 3 automatically closes on the drain interface 11 under its own weight, the weight of the counterweight 8, and the magnetic force of the magnetic plate 12, preventing odor from entering the drain trough 2 from below; at the same time, the sealing plate 20 in the backflow prevention drain core 26 also automatically closes on the water outlet end of the sealing pipe 21 under its own weight and tilt angle, preventing odor from entering the room from the drain pipe 14.

[0046] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.

[0047] Although this article frequently uses terms such as 1. drain body; 2. drain groove; 3. magnetic gravity anti-odor drain core; 4. water seal structure anti-odor pot; 5. groove; 6. cover plate; 7. closing plate; 8. counterweight; 9. drain core shell; 10. fixing ring; 11. drain interface; 12. magnetic plate; 13. pot body; 14. drain pipe; 15. sealing cap; 16. mounting hole; 17. docking ring; 18. water seal groove; 19. mounting pipe; 20. sealing plate; 21. sealing pipe; 22. counterweight; 23. connecting pipe; 24. first sealing ring; 25. second sealing ring; 26. check-back anti-odor drain core, the possibility of using other terms is not excluded.
