Seals and toilet mounting flanges

Abstract

This invention discloses a sealing element and a toilet mounting flange. The sealing element is made of an elastic material and includes an upper ring, a connecting ring, and a lower ring connected sequentially from top to bottom. The upper ring is used to assemble the sealing element onto a flange. The upper and lower ends of the connecting ring are connected to the upper and lower rings, respectively, to form a sewage discharge channel. The inner wall of the connecting ring is connected to the toilet drain pipe. The diameter of the lower ring is smaller than that of the upper ring, and the outer wall of the lower ring is connected to the ground drain pipe. This invention connects the inner wall of the connecting ring to the toilet drain pipe and the outer wall of the lower ring to the ground drain pipe. After the toilet drain pipe and the ground drain pipe are joined, the ground drain pipe will push upwards and deform the lower half of the connecting ring. Under the action of the elastic material, the deformed part of the connecting ring will seal the joint between the toilet drain pipe and the ground drain pipe, ensuring a good sealing effect even if the size of the ground drain pipe is smaller than that of the toilet drain pipe.

Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, and in particular to a well-adaptable sealing element and a toilet mounting flange using the sealing element. Background Technology

[0002] The traditional toilet installation process is as follows: a sewage pipe is pre-embedded in the bathroom floor, the toilet sewage pipe is connected to the floor sewage pipe, and the toilet sewage pipe and the floor sewage pipe are connected by a toilet installation flange, and the joint is sealed with adhesive materials such as grease, putty, and wax ring.

[0003] In practical use, due to changes in building construction standards, the size of the ground sewage pipes in some older buildings is relatively small. However, the existing toilet sewage pipes are designed according to current building construction standards, resulting in incompatibility between commercially available toilet sewage pipes and the ground sewage pipes of older buildings. Using existing installation flanges cannot solve the sealing problem between the two. Furthermore, retrofitting the ground sewage pipes of older buildings is difficult, involves a large amount of work, and is quite costly, making it not a good solution. At the same time, the sealing effect of adhesives such as grease, putty, and wax rings is not ideal. The characteristic of adhesives hardening when cold and softening when hot makes their sealing effect easily affected by ambient temperature and drainage water temperature. Moreover, adhesives are usually individually packaged and transported, requiring the use of release paper for isolation. During use, the release paper must be removed before connecting to the toilet installation flange, making the packaging and installation process more complex and costly. Summary of the Invention

[0004] The purpose of this invention is to provide a sealing element and a toilet mounting flange that can solve the compatibility problem between toilet drain pipes of different sizes and ground drain pipes, and has a stable and efficient sealing effect.

[0005] To achieve the above objectives, one solution of the present invention is:

[0006] A sealing element, made of an elastic material, includes an upper ring body, a connecting ring body, and a lower ring body connected sequentially from top to bottom; the upper ring body is used to assemble the sealing element onto a flange; the upper and lower ends of the connecting ring body are respectively connected to the upper ring body and the lower ring body to form a sewage discharge channel; the inner wall of the connecting ring body is connected to a toilet drain pipe; the diameter of the lower ring body is smaller than the diameter of the upper ring body, and the outer wall of the lower ring body is connected to a ground drain pipe.

[0007] The elastic material is TPE50°.

[0008] The sidewalls of the connecting ring are arc surfaces. Alternatively, the cross-section of the connecting ring is an inverted frustum, larger at the top and smaller at the bottom.

[0009] The inner wall of the connecting ring is recessed to form a foldable groove.

[0010] The cross-section of the foldable groove is triangular, with two corners of the triangle located on the inner wall of the connecting ring.

[0011] The second solution of the present invention is:

[0012] A toilet mounting flange includes the aforementioned sealing element and a flange; the upper ring body is axially limited and fitted within the inner ring of the flange.

[0013] The toilet mounting flange also includes a sealing ring made of elastic material; the sealing ring fits onto the lower surface of the flange.

[0014] The elastic element is made of TPE50°.

[0015] The sealing ring is detachably connected to the lower surface of the flange. Alternatively, the sealing ring is integrally formed on the lower surface of the flange using a mold.

[0016] When the sealing ring is detachable from the flange, the inner ring edge of the upper surface of the sealing ring protrudes to form a ring-shaped boss, and the lower surface of the flange is recessed to form a ring-shaped groove, with the ring-shaped boss embedded in the ring-shaped groove.

[0017] When the sealing ring is detachable from the flange, the upper surface of the sealing ring is provided with a plurality of protrusions, the end circumferential surface of the protrusions is provided with grooves, the flange is provided with mounting holes corresponding to the positions of the protrusions, and the sidewalls of the mounting holes are engaged in the grooves.

[0018] The upper ring body is provided with an annular flange extending outward along its own radial direction; the inner ring edge on the upper surface of the flange is recessed to form a step, and the annular flange fits onto the step. Alternatively, the sealing element is integrally formed onto the flange by a mold.

[0019] When the seal is detachable from the flange, the edge of the annular flange is provided with several snaps; the side wall of the step is provided with snap holes for the snaps to engage.

[0020] In addition, the seal can be integrally formed with the sealing ring using a mold.

[0021] After adopting the above technical solution, the present invention has the following technical effects:

[0022] ① The inner wall of the connecting ring of the sealing element is connected to the toilet drain pipe, and the outer wall of the lower ring of the sealing element is connected to the ground drain pipe. After the toilet drain pipe and the ground drain pipe are connected, the ground drain pipe will push up the lower half of the connecting ring and deform it. Under the action of the elastic material, the deformed part of the connecting ring will seal the connection between the toilet drain pipe and the ground drain pipe. Even if the size of the ground drain pipe is smaller than the size of the toilet drain pipe, a good sealing effect can be guaranteed.

[0023] ② Compared with existing sealing methods that use adhesive materials, the sealing performance of this seal is less affected by ambient temperature and drainage temperature, and its sealing performance is durable and efficient. Attached Figure Description

[0051] Furthermore, this invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0052] refer to Figures 1 to 7 As shown, the present invention discloses a sealing element 1 and a toilet mounting flange using the sealing element 1. The sealing element 1 and the toilet mounting flange will be described in detail below.

[0053] Firstly, the present invention discloses a sealing element 1, which is made of elastic material and includes an upper ring body 11, a connecting ring body 12 and a lower ring body 13 connected from top to bottom;

[0054] The upper ring 11 is used to assemble the seal 1 onto the flange 2;

[0055] The upper and lower ends of the connecting ring 12 are connected to the upper ring 11 and the lower ring 13 respectively to form a sewage discharge channel 10; the inner wall of the connecting ring 12 is connected to the toilet drain pipe a.

[0056] The diameter of the lower ring 13 is smaller than that of the upper ring 11, thus forming a narrowing at the lower end of the connecting ring 12; the outer wall of the lower ring 13 is connected to the ground drain pipe b.

[0057] In some embodiments of the above-described seal 1, the elastic material is TPE50°.

[0058] In some embodiments of the aforementioned seal 1, the sidewall of the connecting ring 12 is an arc surface. Since the lower end of the connecting ring 12 is designed with a constricted opening to connect to the lower ring 13, designing the sidewall of the connecting ring 12 as an arc shape allows for the application of adhesive material 4 to the inner wall of the connecting ring 12 during actual use. After the toilet is installed, the adhesive material 4 will fill the space between the end of the toilet drain pipe a and the inner wall of the connecting ring 12, improving sealing performance. Alternatively, the connecting ring 12 can be designed as an inverted frustum (i.e., a frustum larger at the top and smaller at the bottom) to accommodate the constricted opening at the lower end of the connecting ring 12.

[0059] Furthermore, a folding groove 121 is formed in the inner wall of the connecting ring 12. During actual use, due to the connection between the toilet drain pipe a and the floor drain pipe b, the lower half of the connecting ring 12 will be squeezed upwards and inwards by the floor drain pipe b. By providing the folding groove 121, the deformation of the connecting ring 12 becomes easier and more directional. In this embodiment, the cross-section of the folding groove 121 is triangular, with two corners located on the inner wall of the connecting ring 12. That is, the inner wall of the connecting ring 12 forms a triangular notch as the folding groove 121, making it easier for the connecting ring 12 to deform in a predetermined direction under the pressure of the floor drain pipe b.

[0060] In some embodiments of the above-mentioned sealing element 1, the upper ring body 11 is provided with an annular flange 111 extending outward along its own radial direction. The annular flange 111 can cooperate with the flange 2 to achieve axial positioning of the connecting ring body 12, preventing the sealing element 1 from being pulled off the flange 2 after the toilet drain pipe a is inserted into the inner wall of the connecting ring body 12. Thus, through the positioning effect of the annular flange 111 and the elasticity of the sealing element 1, when the toilet drain pipe a exerts a downward pulling force on the sealing element 1, the upper part of the connecting ring body 12 deforms and comes into close contact with the end of the toilet drain pipe a, thereby improving the sealing performance between the sealing element 1 and the toilet drain pipe a.

[0061] Furthermore, the edge of the aforementioned annular flange 111 is provided with several snap fasteners 112, which allow for detachable installation of the snap fasteners 1 and flange 2, further enhancing the firmness of the seal 1 after assembly on flange 2. Of course, the snap fasteners 112 can also be replaced with a detachable mating structure.

[0062] Secondly, the present invention discloses a toilet mounting flange, which uses the aforementioned sealing element 1 and also includes a flange 2; the upper ring body 11 is axially limited and fitted within the inner ring of the flange 2.

[0063] In this embodiment, the flange 2 is made of ABS.

[0064] In some embodiments of the toilet mounting flange described above, a sealing ring 3 made of elastic material is also included; the sealing ring 3 fits onto the lower surface of the flange 2. The aforementioned sealing element 1 can solve the compatibility and sealing problem between the toilet drain pipe a and the floor drain pipe b. Similarly, by setting the sealing ring 3, the sealing problem between the flange 2 and the floor can be solved. Since the sealing ring 3 itself is made of elastic material, after the toilet mounting flange is installed, the weight of the toilet ceramic body will cause the flange 2 to press down and tighten the sealing ring 3, making the sealing ring 3 tightly connected between the flange 2 and the floor. Even if there is accidental leakage at the junction of the two drain pipes, dirt will not leak out from the gap between the flange 2 and the floor. At the same time, the sealing ring 3 can also act as a buffer between the flange 2 and the floor, preventing rigid contact between the flange 2 and the floor when locking the flange 2 on the floor.

[0065] Furthermore, the material of the aforementioned elastic element is TPE50°.

[0066] Meanwhile, the sealing ring 3 is detachably connected to the lower surface of the flange 2. Since the flange 2 and the sealing ring 3 are made of different materials, their detachable connection facilitates assembly. In this embodiment, the inner ring edge of the upper surface of the sealing ring 3 protrudes to form an annular boss 31, and the lower surface of the flange 2 is recessed to form an annular groove 21. The annular boss 31 is embedded in the annular groove 21 to achieve a limiting fit between the sealing ring 3 and the flange 2. The upper surface of the sealing ring 3 is provided with several protrusions 32, and the end circumference of each protrusion 32 is provided with a groove 321. The flange 2 is provided with mounting holes 22 corresponding to the positions of the protrusions 32. The sidewalls of the mounting holes 22 are engaged within the grooves 321, achieving a detachable connection between the sealing ring 3 and the flange 2. The protrusions 32 can be evenly arranged to improve the force balance between the flange 2 and the sealing ring 3, and to achieve randomness during assembly, without a specific installation direction.

[0067] In some embodiments of the toilet mounting flange described above, the flange 2 is provided with several fixing holes 23 for bolts to pass through to achieve locking between the flange 2 and the ground. Of course, when a sealing ring 3 is provided, a through hole 33 corresponding to the fixing hole 23 needs to be provided on the sealing ring 3 so that the bolt can pass through the sealing ring 3 and be locked into the ground.

[0068] In some embodiments of the toilet mounting flange described above, a step 24 is formed by the recessed inner ring edge on the upper surface of the flange 2. The step 24 matches the annular flange 111, thereby achieving axial positioning of the seal 1 after it is assembled onto the flange 2.

[0069] Furthermore, the side wall of the aforementioned step 24 is provided with a buckle hole 241 for the buckle 112 to engage.

[0070] In some embodiments of the toilet mounting flange described above, the flange 2 is provided with several arc-shaped guide grooves 25 for movable fitting bolts to achieve locking between the flange 2 and the toilet (ceramic body). These arc-shaped guide grooves 25 can each allow the head of a bolt to slide down and be positioned with its threaded portion facing upwards.

[0071] Furthermore, the aforementioned arc-shaped guide groove 25 includes a wide groove portion 251 and a narrow groove portion 252 connected to the wide groove portion 251. During assembly, after the bolt is inverted, its head is inserted downwards through the wide groove portion 251 and then slidably positioned in the narrow groove portion 252.

[0072] Of course, it is conceivable that the aforementioned sealing element 1 and sealing ring 3 can be integrally formed on the flange 2 by a mold to form an integral structure; or, the sealing element 1 and sealing ring 3 can form an integral structure and then be assembled onto the flange 2, such as directly forming the sealing ring 3 on the outer wall of the upper half of the connecting ring body 12.

[0073] refer to Figure 8 As shown, the working principle of this invention is as follows:

[0074] This invention designs a sealing component 1 that is larger at the top and smaller at the bottom. The inner wall of the connecting ring 12 of the sealing component 1 is connected to the toilet drain pipe a, and the outer wall of the lower ring 13 of the sealing component 1 is connected to the ground drain pipe b. During assembly, after the toilet drain pipe a and the ground drain pipe b are connected, the ground drain pipe b will push up the lower half of the connecting ring 12 and deform it. Under the action of the elastic material, the deformed part of the connecting ring 12 will seal the connection between the toilet drain pipe a and the ground drain pipe b. Even if the size of the ground drain pipe b is smaller than the size of the toilet drain pipe a (in reality, the difference between the two will not be very large), a good sealing effect can still be guaranteed. At the same time, compared with the existing sealing method that uses adhesive material 4, the sealing component 1 is not easily affected by the ambient temperature and drainage temperature, and its sealing performance is durable and efficient.

[0075] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
