[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0030] REFERENCE Figures 1-3 An embodiment provided by the utility model: a chimney flue joint sealing structure, comprising chimney pipe 1, the outer wall of chimney pipe 1 is provided with connecting assembly and sealing assembly;

[0031] The sealing assembly includes a sealing ring 12 located at one end of the chimney pipe 1. The main function of the sealing ring 12 is to ensure the sealing between the chimney pipe 1 and other connecting components, prevent gas or liquid leakage, and maintain the high efficiency of the system. It forms a closed space by closely contacting with the connecting components, which plays a role in blocking external air or pollutants. The chimney pipe 1 is fixedly connected with a limiting tube 10 at one end. The function of the limiting tube 10 is to provide stable support for the sealing assembly, ensure that the sealing ring 12 does not deviate or displace during work, thereby maintaining the firmness and stability of the connection. At the same time, the limiting tube 10 also plays a limiting role to prevent the sealing ring 12 from moving beyond the predetermined position when subjected to external force. Each limiting tube 10 is provided with a spring 11 on the outer wall. The main function of the spring 11 is to provide elastic support, which can be appropriately compressed or stretched according to the changes of external pressure or force, to ensure that the sealing ring 12 is always in the appropriate working position. The spring 11 is fixedly connected at one end to the inner wall of the limiting tube 10 and at the other end to the outer wall of the sealing ring 12. The sealing ring 12 is slidably connected to the inner wall of the spring 11. The sealing ring 12 is fixedly connected at one end with a plurality of rubber strips 13. The function of the rubber strips 13 is to further enhance the sealing performance and fill the small gap between the sealing ring 12 and the chimney pipe 1, to ensure that no gas or liquid passes through;

[0032] Specifically, during the device connection process, as the connecting pipe 2 is gradually inserted, the sealing ring 12 will be subjected to external force from the connecting pipe 2. During the extrusion process, the sealing ring 12 will deform along the contact surface. This deformation promotes the sealing ring 12 to closely fit the surface of the connecting pipe 2. The deformation of the sealing ring 12 not only helps to close the pipe interface, but also effectively prevents smoke leakage or external pollutants from entering the pipe system. This extrusion action will further drive the spring 11 to compress. The compression action of the spring 11 is to store energy and prepare to restore to the original state through the rebound force after the external force is removed. By using the rebound force of the spring 11, the extrusion force of the connecting pipe 2 is transferred to the surface of the sealing ring 12. The rebound action of the spring 11 can enhance the compression degree of the sealing ring 12, so that the sealing ring 12 forms a stronger contact pressure on the contact surface with the connecting pipe 2. This enhanced contact pressure can improve the sealing performance and ensure that the connection between the sealing ring 12 and the connecting pipe 2 is more tight, thereby preventing air or other medium leakage. At the same time, the rubber strips 13 are used to fill the small gap between the sealing ring 12 and the connecting pipe 2, further enhancing the sealing of the connection. Since the rubber strips 13 have good elasticity and adaptability, they can automatically fill and compensate for any existing gap under the action of the sealing ring 12, ensuring that there is no risk of gas leakage or other liquid leakage.

[0033] Reference Figure 1 and Figure 2The connecting assembly comprises a plurality of clamping balls 5 located at one end of the chimney pipe 1, a fixed pipe 4 fixedly connected at one end of the chimney pipe 1 for providing support and ensuring the stability of the connecting structure, the clamping ball 5 being slidingly connected inside the fixed pipe 4, a spring 7 provided on the outer wall of the fixed pipe 4, one end of the spring 7 being fixedly connected with a fixed ring 8 for ensuring the stability and position of the spring 7, the other end of the spring 7 being fixedly connected with a blocking ring 6 for limiting the moving range of the clamping ball 5 to prevent excessive sliding or deviation, the inner wall of the fixed ring 8 being fixedly connected with the outer wall of the fixed pipe 4, the inner wall of the blocking ring 6 being slidingly connected with the outer wall of the fixed pipe 4, the inner wall of the blocking ring 6 being in abutment with one side of the clamping ball 5, the outer wall of the blocking ring 6 being fixedly connected with a push-pull pipe 9, the other end of the chimney pipe 1 being fixedly connected with a connecting pipe 2, a plurality of clamping grooves 3 being formed in the connecting pipe 2 for providing a fixed position for the clamping ball 5 to be firmly fixed inside the connecting pipe 2;

[0034] Specifically, during the connection of the two chimney pipes 1, the push-pull pipe 9 is pushed to move, and the blocking ring 6 is moved away from one side of the clamping ball 5 during the movement of the push-pull pipe 9 to provide a moving space for the clamping ball 5, and the blocking ring 6 drives the spring 7 to be compressed during the movement, the spring 7 providing necessary rebound force during the whole process to ensure that all components can be restored in a predetermined manner and reliably connected. Subsequently, the connecting pipe 2 at one end of one of the chimney pipes 1 is moved to the inner wall of the fixed pipe 4 at one end of the other chimney pipe 1, the movement of the connecting pipe 2 ensuring accurate butt joint of the pipes, and the fixed pipe 4 providing a fixed position through the inner wall to prevent deviation or loosening of the pipes during the connection, and then the pulling force on the push-pull pipe 9 is released, the rebounding force of the spring 7 is utilized to push the blocking ring 6 to move to one side of the clamping ball 5 again, so that the clamping ball 5 can smoothly return to the inner wall of the clamping groove 3 to complete the final clamping, which not only enhances the firmness of the connection, but also improves the portability of the connection.

[0035] Working principle: During the connection of the two chimney pipes 1, the push-pull tube 9 is moved. During this movement, the push-pull tube 9 causes the retaining ring 6 to move out from one side of the retaining ball 5, providing space for the retaining ball 5 to move. The retaining ring 6 compresses the spring 7 during its movement, subsequently moving the connecting pipe 2 at one end of one chimney pipe 1 to the inner wall of the fixed pipe 4 at the other chimney pipe 1. Then, the pulling force on the push-pull tube 9 is released, and the rebound force of the spring 7 pushes the retaining ring 6 back to one side of the retaining ball 5, pushing... The ball 5 is inserted into the inner wall of the slot 3, enabling convenient connection between the two chimney pipes 1. During the movement of the connecting pipe 2, the sealing ring 12 is squeezed. During the squeezing process, the sealing ring 12 drives the spring 11 to compress. The rebound force of the spring 11 is used to rebound this squeezing force to the surface of the sealing ring 12, enhancing the tightness of the connection between the sealing ring 12 and the connecting pipe 2. At the same time, the rubber strip 13 is used to fill the gap between the sealing ring 12 and the connecting pipe 2, enhancing the sealing of the connection between the two chimney pipes 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
