Technical Field

[0001] The utility model belongs to the technical field of floor drains, and particularly relates to a new type of floor drain core. Background Technique

[0002] The floor drain core, also known as the floor drain odor prevention device, is a device used to transform old floor drains that do not prevent odors and can be installed in the original old floor drains to achieve the purpose of preventing odors. It can be classified into water-sealed floor drain cores and mechanical floor drain cores. The bottom of the mechanical floor drain core has a closable sealing plate, and the sealing plate is rotatably connected to the floor drain core through a rotating shaft. The sealing plate is opened by the gravity of water for drainage, and when there is no water or little water, the sealing plate is automatically closed by the pressure of the counterweight. However, the rotating shaft and the floor drain core are of a split structure, resulting in greater assembly difficulty between the rotating shaft, the sealing plate, and the floor drain core, more parts, easy entry of sundries leading to rotational blockage, poor sealing performance, and easy rusting of the counterweight when encountering water.

[0003] Therefore, a new type of floor drain core with a simple structure, easy to assemble, and not easily blocked is urgently needed. Content of the Utility Model

[0028] Embodiment 1:

[0029] In this embodiment, a new type of floor drain core, as Figures 1 to 4As shown in the figure, it includes a core barrel 1 and a cover plate 2 rotatably connected to the bottom of the core barrel 1. Specifically, an inclined partition 3 is provided inside the core barrel 1, and the inclined partition 3 divides the core barrel 1 into a water outlet chamber 4 and a water isolation chamber 5. The top edge and both side edges of the inclined partition 3 are connected to the inner wall of the core barrel 1. The upper end of the water outlet chamber 4 is the water inlet end and the lower end is the drainage end. The upper end of the water isolation chamber 5 is closed and the lower end is open. The bottom edge of the inclined partition 3 separates the drainage end of the water outlet chamber 4 from the open lower end of the water isolation chamber 5. The cover plate 2 includes a counterweight plate 6 and a water sealing plate 7 integrally connected to the counterweight plate 6 at an angle. Two symmetric convex shafts 8 are extended on the barrel wall of the lower part of the water isolation chamber 5 close to the inclined partition 3. Two hinge seats 9 matching the convex shafts 8 are provided at one end of the water sealing plate 7 close to the counterweight plate 6. The hinge seat 9 is provided with an opening 10. The hinge seat 9 is rotatably buckled on the convex shaft 8 through the opening 10 so that the water sealing plate 7 opens or closes the water outlet chamber 4 from the bottom during rotation. The counterweight plate 6 plays a role in counterweight control for the rotation of the water sealing plate 7. When the water volume is large, the self-weight of the water is greater than the weight of the counterweight plate 6, causing the water sealing plate 7 to rotate forward and open the water outlet chamber 4. When the water volume is small, the weight of the counterweight plate 6 is greater than the self-weight of the water, causing the water sealing plate 7 to flip and close the water outlet chamber 4.

[0030] With this structure, the integrated design of the convex shaft 8 and the core barrel 1 reduces the number of parts and assembly processes. The hinge seat 9 with an opening 10 is more easily buckled and connected to the convex shaft 8, ensuring the rotational stability of the cover plate 2. The structure is simpler, not easily blocked by debris, and the combined assembly makes disassembly and assembly more convenient.

[0031] As an optimized implementation manner of this embodiment, as Figure 3 shown, the counterweight plate 6 is provided with a groove, the notch of the groove is arranged upward, and a counterweight block 11 is provided in the groove. The counterweight block 11 is a metal block, and the counterweight block 11 makes the water sealing plate 7 always close the water outlet chamber 4 during idle time.

[0032] Furthermore, a thermoplastic plate 12 is provided at the notch of the groove. The thermoplastic plate 12 ultrasonically melts and seals the groove, thus completely closing the notch of the groove. The hot melt adhesive completely wraps the counterweight block 11, preventing the counterweight block 11 from rusting and eliminating the need for electroplating anti-rust treatment.

[0033] In this embodiment, a circle of sealing strip 13 is provided on the edge of the water sealing plate 7. The shape of the water sealing plate 7 matches the bottom of the cavity wall of the water outlet cavity 4. When the water sealing plate 7 closes the water outlet cavity 4, the sealing strip 13 is tightly attached to the bottom of the cavity wall of the water outlet cavity 4. The sealing strip 13 is a soft rubber strip. Under the force applied by the counterweight plate 6, both sides of the sealing strip 13 are squeezed by the bottom of the cavity wall of the water outlet cavity 4 and the water sealing plate 7, so that the bottom of the cavity wall of the water outlet cavity 4 can be partially embedded in the sealing strip 13, thereby having better sealing performance.

[0034] It is worth noting that when the amount of water is small, the weight of the water cannot overcome the gravity of the above-mentioned counterweight plate 6, and the above-mentioned water sealing plate 7 will not be opened, so that a small amount of water is retained in the above-mentioned water outlet chamber 4, which plays the role of water sealing and odor isolation.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a limit plate 14, which is arranged at the bottom of the water outlet chamber 4 and below the counterweight plate 6. When the water sealing plate 7 closes the water outlet chamber 4, the counterweight plate 6 fits against the upper surface of the limit plate 14. When the water sealing plate 7 fully opens the water outlet chamber 4, the water sealing plate 7 fits against the end surface of the limit plate 14 and the counterweight plate 6 fits against the inclined partition 3. The water sealing plate 7 is used to constrain the rotation starting position of the cover plate 2, so that the cover plate 2 will not be unable to return to its original position due to excessive rotation angle, thereby ensuring the reliability of the water sealing plate 7 in closing the water outlet chamber 4.

[0036] Specifically, the side wall where the above-mentioned limit plate 14 connects with the wall of the core tube 1 is an arc-shaped wall, and an arc-shaped convex strip 15 is provided at the bottom of the above-mentioned arc-shaped wall. The inner side of the wall of the above-mentioned core tube 1 is provided with an arc-shaped groove 16, and the above-mentioned arc-shaped convex strip 15 is embedded in the above-mentioned arc-shaped groove 16. When water is discharged, the above-mentioned cover plate 2 rotates to make the water sealing plate 7 laterally close to the side of the above-mentioned limit plate 14. The above-mentioned arc-shaped convex strip 15 and the arc-shaped groove 16 constrain the position of the above-mentioned limit plate 14 in the circumferential direction, so that the above-mentioned limit plate 14 will not be displaced or moved laterally, and at the same time, it also partially blocks the mouth of the above-mentioned water-isolating cavity 5, effectively preventing most of the water from splashing into the above-mentioned water-isolating cavity 5.

[0037] Further, such as Figure 4 and Figure 5As shown in the figure, internal engaging teeth 17 are provided on the inner side of the barrel wall of the above-mentioned core barrel 1 near the above-mentioned convex shaft 8. External engaging teeth 18 are provided at both ends of the above-mentioned limiting plate 14 corresponding to the positions of the internal engaging teeth 17. The above-mentioned limiting plate 14 is clamped on the above-mentioned core barrel 1 through the cooperation of the external engaging teeth 18 and the internal engaging teeth 17. When there is no water flowing out, the counterweight plate 6 of the above-mentioned cover plate 2 vertically presses tightly on the top surface of the above-mentioned limiting plate 14. The internal engaging teeth 17 and the external engaging teeth 18 limit the position of the above-mentioned limiting plate 14 vertically, so that the above-mentioned limiting plate 14 will neither move up nor move down.

[0038] In this embodiment, as Figure 1 shown, a wide-mouth portion 19 extends from the top of the above-mentioned core barrel 1. The shape of the above-mentioned wide-mouth portion 19 is an inverted cone-shaped barrel. An outer edge 20 is provided at the top of the above-mentioned wide-mouth portion 19. The above-mentioned outer edge 20 is used for lapping on the top plane of the floor drain. An annular rib 21 is provided on the outer wall of the above-mentioned wide-mouth portion 19. A U-shaped sealing ring 22 is sleeved on the above-mentioned annular rib 21. The above-mentioned U-shaped sealing ring 22 is used to enhance the sealing performance between the floor drain core and the inner wall of the floor drain. It should be noted that the top of the floor drain is self-equipped with a filter screen, which can block most sundries, and small impurities directly pass through the water outlet cavity 4 and are discharged with the water flow.

[0039] It further includes a lifting hook 23. Two mounting holes are symmetrically provided on the inner wall of the above-mentioned wide-mouth portion 19. Both ends of the above-mentioned lifting hook 23 are rotatably connected in the above-mentioned mounting holes, so as to facilitate taking out the above-mentioned core barrel 1 from the floor drain through the above-mentioned lifting hook 23.

[0040] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
