Description

Technical Field

[0001] This application relates to the field of building drainage, and in particular to a vent connector for a drainage riser. Background Technology

[0002] Currently, if the toilet drain pipe is not equipped with an effective vent pipe, the negative pressure inside the pipe during drainage may break the water seal (water in the trap), causing harmful gases to enter the room from the sewer. According to the "Code for Design of Building Water Supply and Drainage", the drain pipe of sanitary ware should be equipped with a vent pipe to balance the air pressure inside and outside the pipe and prevent the water seal from failing. In older buildings, a separate vent riser is often not installed, and only a drain pipe is installed. However, with the improvement of people's living standards, the requirements for indoor air quality are also getting higher and higher. For the conversion of squat toilets to sit-down toilets, in order to prevent toxic and harmful pollutants from spreading into the living environment, a separate vent pipe needs to be installed and connected to the existing drain riser.

[0003] However, existing vent connectors typically require drilling holes in the drain pipe before installation. Since drain pipes are usually shared with residents above, drilling can easily lead to downstairs residents using the drain pipe, causing sewage to flow out through the holes and resulting in widespread pollution. Furthermore, the vent pipes of existing vent connectors are usually suspended directly outside, which can easily lead to damage to external connectors and changes in the position of the vent pipe over time. Utility Model Content

[0004] To address the issue that during installation, the downstairs neighbor may use the sewer system, causing sewage to drain through the drilled holes and resulting in widespread pollution, this application provides a drainage riser vent connector.

[0005] The drainage riser vent connector provided in this application adopts the following technical solution: it includes a connector, with cable ties fixed through and fixed to the top and bottom of one side of the connector, a connecting pipe movably sleeved through the middle of the connector, a threaded tapered head fixed to one end of the connecting pipe, a connector head fixed to the other end of the connecting pipe, a vent pipe connected to the outer wall of the connector head, a hexagonal sleeve fixed to the outer wall of the connecting pipe near the connector head, a first vent hole opened through the bottom of the other end of the connecting pipe, a connecting ring movably sleeved through the outer wall of the vent pipe, a support rod fixed to the bottom of the connecting ring, a connecting block fixed to the bottom of the support rod, a bolt threaded through and connected to one side of the connecting block, and a second vent hole opened through the bottom of the other end of the vent pipe.

[0006] By adopting the above technical solution, during installation, the threaded cone can be rotated into the drainage riser by turning the hexagonal sleeve with a hexagonal wrench. The gas inside the drainage riser is then discharged to the outside through the first vent hole, introduced into the connecting pipe, and then discharged to the outside through the vent pipe and the second vent hole.

[0007] Preferably, an indicator arrow is provided on one side of the outer wall of the hexagonal sleeve, and the indicator arrow and the first vent hole are located at the top and bottom of the connecting pipe, respectively.

[0008] By adopting the above technical solution, the position of the first vent hole inside the drainage riser can be determined by the indicator arrow. After installation, the indicator arrow is kept directly above the hexagonal sleeve, thereby ensuring that the first vent hole is located inside the drainage riser and facing directly downwards, thus preventing sewage inside the drainage riser from blocking the first vent hole.

[0009] Preferably, a sealing ring is fixed to the outer wall of the connector, and multiple sealing rings are provided, which are arranged horizontally and equidistantly.

[0010] By adopting the above technical solution, multiple sealing rings are used to fill the gap between the connector and the vent pipe, allowing the vent pipe to discharge the gas inside the connector to the outside.

[0011] Preferably, multiple connecting rings and support rods are provided, and the height of the support rods is set in a stepped manner, with the support rods closer to the connecting piece having shorter heights.

[0012] By adopting the above technical solution, the ventilation pipe is supported by support rods of different heights, which cause the fixed ventilation pipe to extend outward in an upward state.

[0013] Preferably, the connecting block is U-shaped, with one end of the bolt penetrating the connecting block and the other end abutting against the inner wall of the connecting block.

[0014] By adopting the above technical solution, when installing the support rod, the connecting block can be connected to the keel of the bathroom ceiling, and the connecting block can be fixed to the keel by rotating the bolt.

[0015] Preferably, the vent pipe is closed at the end away from the connector, and the top of the second vent hole is located in the middle of the vent pipe. A soft rubber sleeve is fixed to the outside of the through hole on the side of the connector near the threaded cone.

[0016] By adopting the above technical solution, water seepage into the vent pipe port is prevented. At the same time, the soft rubber sleeve will deform under pressure, which can fill the gap between the drainage riser and the connecting pipe, thus preventing water seepage.

[0017] Preferably, the connector has an arc-shaped groove on the side near the threaded cone, and a protrusion is fixed in the middle of the arc-shaped groove. Multiple protrusions are provided, and the multiple protrusions are arranged vertically at equal intervals, with the top of the protrusions being pointed.

[0018] By adopting the above technical solution, the arc-shaped connector can fit tightly with the drainage riser. The pointed protrusions squeeze and penetrate the outside of the drainage riser, making the connection between the connector and the drainage riser tighter.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application involves placing the arc-shaped groove of the connector at the location where air needs to be vented in the drainage riser, then pressing the connector firmly. The pointed protrusions squeeze and penetrate the outside of the drainage riser, making the connection between the connector and the drainage riser tighter. Then, a cable tie is tied to the outside of the drainage riser. After tightening, a hex wrench is used to rotate the hexagonal sleeve to rotate the threaded cone into the inside of the drainage riser. After installation, the indicator arrow is kept directly above the hexagonal sleeve, thus achieving the effect of direct installation. Installation is completed when drilling.

[0021] 2. This application connects the connecting block to the keel of the bathroom ceiling, fixes the connecting block to the keel by rotating bolts, and supports the vent pipe with support rods of different heights so that the fixed vent pipe extends outward in an upward state. In use, the gas inside the drain riser is discharged to the outside through the first vent hole, introduced into the connecting pipe, and then discharged to the outside through the vent pipe and the second vent hole. The vent pipe is fixed indoors, thereby achieving a more stable installation of the vent pipe and less susceptibility to external influences. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a vent connector for a drainage riser, including a connector 1. Cable ties 4 are fixedly inserted through the top and bottom of one side of the connector 1. A connecting pipe 6 is movably sleeved through the middle of the connector 1. A threaded cone 7 is fixed to one end of the connecting pipe 6, and a connector 9 is fixed to the other end. A vent pipe 13 is connected to the outer wall of the connector 9. A hexagonal sleeve 11 is fixed to the outer wall of the connecting pipe 6 near the connector 9. During installation, a hexagonal wrench can be used to rotate the hexagonal sleeve 11 to rotate the threaded cone 7 into the drainage riser. The bottom of the other end of the connecting pipe 6... A first vent hole 8 is provided through the vent pipe 13. A connecting ring 15 is movably sleeved on the outer wall of the vent pipe 13. A support rod 16 is fixed at the bottom of the connecting ring 15. The support position of the support rod 16 can be adjusted by moving the position of the connecting ring 15. A connecting block 17 is fixed at the bottom of the support rod 16. A bolt 18 is threaded through one side of the connecting block 17. A second vent hole 14 is provided through the bottom of the other end of the vent pipe 13. The gas inside the drainage riser is discharged to the outside through the first vent hole 8, introduced into the connecting pipe 6, and then discharged to the outside through the vent pipe 13 and the second vent hole 14.

[0029] Reference Appendix Figure 2 The hexagonal sleeve 11 has an indicator arrow 12 on one side of its outer wall. The indicator arrow 12 and the first vent hole 8 are located at the top and bottom of the connecting pipe 6, respectively. The position of the first vent hole 8 inside the drainage riser is determined by the indicator arrow 12. After installation, the indicator arrow 12 is kept directly above the hexagonal sleeve 11 to ensure that the first vent hole 8 is located inside the drainage riser and faces directly downward, thus preventing sewage inside the drainage riser from blocking the first vent hole 8.

[0030] Reference Appendix Figure 4 The outer wall of the connector 9 is fixed with a sealing ring 10. Multiple sealing rings 10 are provided and are arranged horizontally at equal intervals. The multiple sealing rings 10 fill the gap between the connector 9 and the vent pipe 13, so that the vent pipe 13 can exhaust the gas inside the connector 6 to the outside.

[0031] Reference Appendix Figure 1Multiple connecting rings 15 and support rods 16 are provided. The height of the support rods 16 is set in a stepped manner. The support rods 16 closer to the connector 1 have shorter heights. The vent pipe 13 is supported by the support rods 16. The support rods 16 with different heights make the fixed vent pipe 13 extend outward in an upward state.

[0032] Reference Appendix Figure 1 The connecting block 17 is U-shaped. One end of the bolt 18 passes through the connecting block 17 and the other end abuts against the inner wall of the connecting block 17. When installing the support rod 16, the connecting block 17 can be connected to the keel of the bathroom ceiling. The connecting block 17 can be fixed to the keel by rotating the bolt 18.

[0033] Reference Appendix Figure 1 The vent pipe 13 is closed at the end away from the connector 1, and the top of the second vent hole 14 is located in the middle of the vent pipe 13. A soft rubber sleeve 5 is fixed to the outside of the through hole on the side of the connector 1 near the threaded cone 7 to prevent water from seeping into the vent pipe 13. At the same time, the soft rubber sleeve 5 will deform when it is squeezed by pressure, which can fill the gap between the drainage riser and the connecting pipe 6 to avoid water leakage.

[0034] Reference Appendix Figure 3 The connector 1 has an arc-shaped groove 2 on the side near the threaded cone 7. A protrusion 3 is fixed in the middle of the arc-shaped groove 2. There are multiple protrusions 3, which are arranged vertically at equal intervals. The top of the protrusions 3 is pointed. The arc-shaped connector 1 can fit tightly with the drainage riser. The pointed protrusions 3 squeeze and penetrate into the outside of the drainage riser, making the connection between the connector 1 and the drainage riser tighter.

[0035] The implementation principle of a drainage riser vent connector according to an embodiment of this application is as follows: First, place the arc-shaped groove 2 of the connector 1 at the location where ventilation is required in the drainage riser. Then, press the connector 1 firmly, and the pointed protrusion 3 will press and insert it into the outside of the drainage riser, making the connection between the connector 1 and the drainage riser tighter. Then, tie the cable tie 4 to the outside of the drainage riser. After tightening, use a hex wrench to rotate the hexagonal sleeve 11 to rotate the threaded cone 7 into the inside of the drainage riser. After installation, keep the indicator arrow 12 directly above the hexagonal sleeve 11 to ensure that the first vent 8 is located inside the drainage riser and faces directly downwards, preventing sewage inside the drainage riser from blocking the first vent 8. Then, the vent pipe 13 is connected to the connector 9. Multiple sealing rings 10 are installed to fill the gap between the connector 9 and the vent pipe 13, so that the vent pipe 13 can exhaust the gas inside the connector pipe 6 to the outside. Then, the connecting block 17 is connected to the keel of the bathroom ceiling. The connecting block 17 is fixed to the keel by rotating the bolt 18. The vent pipe 13 is supported by the support rod 16. The support rods 16 of different heights make the fixed vent pipe 13 extend outward in an upward state. When in use, the gas inside the drain riser is exhausted to the outside through the first vent hole 8, introduced into the connector pipe 6, and then exhausted to the outside through the vent pipe 13 and the second vent hole 14.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
