Detailed Implementation

[0019] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0020] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0024] In the existing technology, the exhaust port of the door is equipped with a sealing ring. The sealing ring is put into the exhaust pipe by closing the door. The closing action is a process of changing the door from an angle to a flat surface. The inner diameter of the sealing ring needs to be 5mm larger than the outer diameter of the exhaust pipe in order to be put into the exhaust pipe by closing the door. However, this 5mm gap cannot achieve the purpose of sealing and zero leakage. As a result, the flue gas in the exhaust pipe leaks into the box through the gap between the exhaust pipe and the sealing ring.

[0025] Combination Figures 1 to 5 As shown, this utility model provides a smoke exhaust pipe 10 structure, including: a smoke exhaust pipe 10 having a smoke exhaust end 110; a sealing member 20 disposed at the smoke exhaust end 110; and a door 30 having a smoke exhaust port 310. When the door 30 is in the closed state, the smoke exhaust port corresponds to the smoke exhaust pipe 10, and the end face of the door 30 abuts against the end face of the sealing member 20 to form a sealing boundary 210, which surrounds the smoke exhaust port.

[0026] Specifically, the exhaust pipe 10 is used in conjunction with the burner, and the flue gas generated by the burner is discharged through the exhaust pipe 10. The exhaust end 110 of the exhaust pipe 10 (i.e., the end of the exhaust pipe 10 near the door 30) is equipped with a sealing element 20, which can be understood as a sealing ring. The door 30 has an open state and a closed state. When the door 30 is in the closed state, the exhaust port corresponds to the exhaust pipe 10, ensuring that the flue gas discharged from the exhaust pipe 10 can only be discharged through the exhaust port. Furthermore, the end faces of the door 30 and the sealing element 20 abut against each other to form a sealing boundary 210. The sealing boundary 210 surrounds the exhaust port, and the sealing boundary 210 is used to seal and prevent flue gas leakage through the connection between the sealing element 20 and the door 30, achieving zero leakage between the exhaust pipe 10 and the door 30. When the door 30 is in the open state, the exhaust pipe 10, the sealing element 20, the burner, etc., can be displayed, facilitating maintenance operations by users or staff.

[0027] This application abandons the existing technology of setting the sealing ring on the door body 30 and making the sealing ring fit into the exhaust pipe 10 when the door is closed. Instead, the sealing element 20 is set on the exhaust pipe 10 and formed as an integral part. After the door body 30 is closed, the inner side of the door body 30 and the sealing element 20 make a surface-to-surface fit to form a sealing boundary 210, thereby improving the sealing effect.

[0028] In this embodiment, the exhaust end 110 is provided with an exhaust pipe bracket 120, which is connected to the sealing member 20. The exhaust pipe bracket 120 helps to better fix the sealing member 20 to the exhaust end 110, ensuring that the sealing member 20 is not easily displaced or detached during long-term use.

[0029] Furthermore, the exhaust pipe bracket 120 is sleeved on the exhaust pipe 10, and the exhaust pipe bracket 120 has a positioning part 121 extending outward in the radial direction; the sealing element 20 is sleeved on the positioning part 121. Through the above design, the positioning part 121 provides stable support and positioning for the sealing element 20, enabling the sealing element 20 to be accurately installed at a predetermined position on the exhaust pipe 10, further enhancing the connection stability between the sealing element 20 and the exhaust pipe 10. Moreover, the sealing element 20 can be replaced as needed, avoiding a decrease in sealing effect due to aging of the sealing element 20. In addition, the outward extension of the positioning part 121 facilitates the positioning and installation of the sealing element 20 by the operator during installation, improving installation efficiency.

[0030] Furthermore, the sealing element 20 includes a mounting portion 201, which has a mounting groove 202. The mounting groove 202 is inserted into and engages with the positioning portion 121. This embodiment makes the connection between the sealing element 20 and the exhaust pipe bracket 120 tighter and more stable. The size and shape of the mounting groove 202 are adapted to the positioning portion 121, ensuring that the positioning portion 121 is accurately inserted into the mounting groove 202, preventing loosening or shaking during installation or use. At the same time, the edges of the mounting groove 202 are specially treated to have a certain degree of elasticity and toughness, providing a certain buffering and wrapping effect when the positioning portion 121 is inserted, preventing damage to the sealing element 20 due to excessive compression.

[0031] Furthermore, the sealing element 20 also includes a top abutment portion 203, which is connected to the mounting portion 201. When the door 30 is in the closed state, the end face of the top abutment portion 203 abuts against the door 30 to form the sealing boundary 210. In the closed state, the top abutment portion 203 fits tightly against the door 30. This design not only enhances the sealing performance and effectively prevents smoke leakage from the exhaust pipe 10, but also provides cushioning and shock absorption. The top abutment portion 203 is made of an elastic material, which can adaptively adjust to the slight deformation of the door 30, ensuring the stability and reliability of the sealing boundary 210.

[0032] Furthermore, when the door 30 is in the closed state, the top abutment 203 is arranged around the smoke vent. This arrangement of the top abutment 203 around the smoke vent ensures a complete seal, preventing smoke leakage from the gap between the smoke vent and the door 30. Moreover, the surrounding arrangement increases the contact area between the top abutment 203 and the door 30, further enhancing the cushioning and shock absorption effect. Even during RV travel, when encountering bumps or other rough terrain, the top abutment 203 remains tightly fitted to the door 30, maintaining a good seal and ensuring the stable operation of the smoke vent 10 structure.

[0033] In this embodiment, the exhaust pipe support 120 is provided with a plurality of connecting portions 122, which are spaced apart and attached to the exhaust pipe 10; one or more of the connecting portions 122 are connected to the exhaust pipe 10 at connection points. The arrangement of the plurality of connecting portions 122 makes the connection between the exhaust pipe support 120 and the exhaust pipe 10 more stable, effectively dispersing the stress generated during the welding process between the exhaust pipe 10 and the exhaust pipe support 120, and avoiding damage to the exhaust pipe 10 due to local stress concentration.

[0034] Furthermore, the exhaust pipe 10 is provided with a positioning hole 101; one or more of the connecting parts 122 are provided with positioning protrusions 123. The positioning protrusions 123 cooperate with the positioning holes 101 to accurately and temporarily position the exhaust pipe bracket 120 on the exhaust pipe 10, ensuring that each connecting part 122 can accurately correspond to the appropriate position on the exhaust pipe 10, greatly improving the accuracy and efficiency of installation, so as to facilitate the subsequent welding of the exhaust pipe 10 to the exhaust pipe bracket 120.

[0035] This utility model also provides a RV water heater, which includes: a housing 40; and a flue pipe 10 structure as described above; the door 30 is rotatably connected to the housing 40; the door 30 is rotatable relative to the housing 40 and has a closed state and an open state.

[0036] This utility model also provides a motorhome, which includes the motorhome water heater described above.

[0037] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
