Description

Technical Field

[0001] This utility model belongs to the field of flue construction technology, and in particular relates to a wall-penetrating structure for a water heater flue. Background Technology

[0002] A water heater exhaust pipe penetrating a wall refers to the construction process where the exhaust pipe passes through the building wall during the installation of a water heater. This operation aims to safely vent the exhaust gases produced by the water heater to the outside, preventing the accumulation of exhaust gases indoors and harming human health. During construction, attention must be paid to the sealing, waterproofing, and fixing between the exhaust pipe and the wall to prevent rainwater backflow and exhaust gas leakage. At the same time, it is necessary to ensure that the exhaust pipe is stable. A properly constructed water heater exhaust pipe penetrating the wall can ensure the normal operation of the water heater, improve the safety of use, and maintain the structural integrity of the building and the health of the indoor environment.

[0003] During the installation of water heaters, the wall-penetrating structure of the exhaust pipe is crucial for ensuring the safe and stable operation of the water heater and the waterproofing and sealing performance of the house. However, the wall-penetrating structure may lack effective positioning and fixing devices, causing the exhaust pipe to easily shake or shift at the wall penetration point. Furthermore, the sealing treatment between the exhaust pipe and the wall is often inadequate, easily resulting in gaps that lead to exhaust gas leakage and rainwater backflow. Therefore, it is necessary to provide a wall-penetrating structure for water heater exhaust pipes that can accurately position the exhaust pipe within the pre-embedded pipe cavity through indoor and outdoor positioning rings, ensuring its stable installation position. At the same time, the rubber bushing and tie rod assembly work together to not only effectively seal the pre-embedded pipe and both sides of the exhaust pipe to prevent exhaust gas leakage and rainwater backflow, but also further enhance the overall stability through tie rod fixing. Utility Model Content

[0004] The purpose of this utility model is to provide a wall-penetrating structure for a water heater exhaust pipe, which can accurately position the exhaust pipe within the pre-embedded pipe cavity through indoor and outdoor positioning rings, ensuring its stable installation position.

[0015] Figure 1-4This invention illustrates a wall-penetrating structure for a water heater exhaust pipe according to an embodiment of the present invention. It includes an embedded pipe 1 pre-embedded within the wall. A water-stop ring 2 is fixedly connected to the surface of the embedded pipe 1, and the water-stop ring 2 is also pre-embedded inside the wall. An exhaust pipe 3 penetrates the inner cavity of the embedded pipe 1. Semi-circular pins 14 are integrally molded on the top and bottom of the left side of the inner cavity of the exhaust pipe 3. The semi-circular pins 14 are inserted into the inner cavity of an injection hole 10. Through the injection hole 10, the user can easily fill the space between the embedded pipe 1 and the exhaust pipe 3 with expanding sealant 7, thereby ensuring that the expanding sealant 7 is evenly and fully distributed on the surface of the exhaust pipe 3 and the inner cavity of the embedded pipe 1. An indoor positioning ring 4 is engaged on the left side of the pre-embedded pipe 1. Injection holes 10 are provided at the top and bottom of the left side of the indoor positioning ring 4, and these holes are connected to the inner cavity of the pre-embedded pipe 1. An outdoor positioning ring 5 is engaged on the right side of the pre-embedded pipe 1. Multiple ring-shaped positioning plates 9 are integrally molded on the surfaces of both the indoor positioning ring 4 and the outdoor positioning ring 5. The surfaces of the positioning plates 9 are tightly fitted to the inner wall of the pre-embedded pipe 1. Through the positioning plates 9, the indoor positioning ring 4, the outdoor positioning ring 5, and the pre-embedded pipe 1 are engaged and connected, allowing the exhaust pipe 3 to be stably positioned in the middle of the inner cavity of the pre-embedded pipe 1, thus facilitating the subsequent filling of the foamed sealant 7. The indoor positioning ring 4 and the outdoor positioning ring 5 are uniformly and fully fitted with rubber bushings 6 on opposite sides. The rubber bushings 6 are fitted onto the surface of the exhaust pipe 3. Foamed sealant 7 is filled between the embedded pipe 1 and the exhaust pipe 3. A pull assembly 8 is provided between the indoor positioning ring 4 and the outdoor positioning ring 5. The pull assembly 8 includes pull rods 81 located on the front and rear sides of the exhaust pipe 3, respectively. The two ends of the pull rods 81 pass through the outer sides of the indoor positioning ring 4 and the outdoor positioning ring 5, respectively. A through hole 82 adapted to the pull rod 81 is opened on opposite sides of the indoor positioning ring 4 and the outdoor positioning ring 5. The pull rod 81 passes through the inner side of the through hole 82. The cavity has a threaded connection of nut 83 to the surface of the pull rod 81. The surfaces of the indoor positioning ring 4 and the outdoor positioning ring 5 are both fitted with sealing gaskets 84. The sealing gaskets 84 are tightly fitted to the side of the pre-embedded pipe 1. A rain shelter 11 is provided on the right side of the pre-embedded pipe 1. The rain shelter 11 is fitted on the surface of the pre-embedded pipe 1. Arc-shaped grooves 12 are opened on the front and rear sides of the bottom of the rain shelter 11.

Two covers 13 are fitted on the left side of the surface of the pre-embedded pipe 1. The right side of the covers 13 is tightly fitted to the wall. The edges of the covers 13 and the wall are coated with sealant.

[0016] Working principle: In use, the user engages the indoor positioning ring 4 and the outdoor positioning ring 5 on both sides of the pre-embedded pipe 1, then inserts the pull rod 81 into the inner cavity of the through hole 82, and fits the arc-shaped groove 12 onto the right side of the surface of the pull rod 81. The nut 83 is then screwed onto the surface of the pull rod 81, and the indoor positioning ring 4 and the outdoor positioning ring 5 are threadedly fixed using the nut 83. Finally, the user inserts the exhaust pipe 3 into the inner cavity of the pre-embedded pipe 1, so that the indoor positioning ring... 4. The outdoor positioning ring 5 and the rubber bushing 6 are both fitted onto the surface of the exhaust pipe 3. Then, the user seals the space between the pre-embedded pipe 1 and the exhaust pipe 3 through the inner cavity of the injection hole 10. After that, the cover 13 is fitted onto the left end of the pre-embedded pipe 1, and the semi-circular pin 14 is inserted into the inner cavity of the injection hole 10. After the foam sealant 7 has completely solidified, the cover 13 is fixed by bonding the semi-circular pin 14. Finally, the edge of the cover 13 and the wall is sealed.

[0017] In summary, the wall-penetrating structure of this water heater exhaust pipe, through the combined use of the indoor positioning ring 4 and the outdoor positioning ring 5, positions the exhaust pipe 3 within the cavity of the pre-embedded pipe 1. Furthermore, through the combined use of the rubber bushing 6 and the tie rod assembly 8, the positions on both sides of the pre-embedded pipe 1 and the exhaust pipe 3 are sealed and secured by tie rods, thus achieving stable and secure installation and a tight connection.
