[0002] Nowadays, building flues are equipped with cement flues for airflow. Cement flues consist of modularly designed flue sections and flue connecting sections. After the flue connecting section is connected to the flue section, there will be gaps, resulting in poor sealing. These gaps can lead to smoke leakage, and smoke or other odors can seep into the room through the gaps, causing unpleasant smells. Utility Model Content

For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0021] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0022] like Figures 1-4 The novel flue sealing structure shown includes a connecting cylinder 1 for connecting a first flue duct 6 and a second flue duct 7. A mounting frame is provided on the outer side of the connecting cylinder 1, and sealing strips 4 are respectively provided on the upper and lower sides of the mounting frame. The sealing strips 4 are used to seal the gap between the upper side of the mounting frame and the bottom of the first flue duct 6, and to seal the gap between the lower side of the mounting frame and the top surface of the second flue duct 7. The sealing strips 4 are approximately 10mm thick and are the soft sealing strips found in existing technology.
[0023] In this embodiment, the first flue duct 6 and the second flue duct 7 are installed through the connecting cylinder 1. A first gap is formed between the upper side of the mounting frame and the first flue duct 6, and a second gap is formed between the lower side of the mounting frame and the second flue duct 7. Under the action of gravity, the first flue duct 6 and the connecting cylinder 1 press the sealing strip 4, and the sealing strip 4 seals the first gap and the second gap, reducing the gap and preventing smoke leakage.
[0024] The mounting bracket includes a first connecting pipe 201 and a second connecting pipe 202; the first connecting pipe 201 extends longitudinally to the outer walls on both sides of the flue, and the two ends of the second connecting pipe 202 are connected to the first connecting pipe 201. Specifically, the two ends of the second connecting pipe 202 are fixedly connected to the side walls of the first connecting pipe 201.
[0025] In this embodiment, the mounting bracket has a simple structure, making it easy to install and use. After the first connecting pipe 201 and the second connecting pipe 202 are connected, they can better support the first flue duct 6 and the second flue duct 7, while controlling the number and position of gaps, making it convenient to place the sealing strip 4 for sealing.
[0026] A connecting rod 5 is installed inside the first connecting pipe 201, and the length of the connecting rod 5 is greater than the length of the first connecting pipe 201. The connecting rod 5 is a steel bar with a diameter of about 15mm.
[0027] In this embodiment, the first connecting rod 5 is used to insert into the first connecting tube 201, and both ends of the first connecting rod 5 are used to insert into designated positions to support the first connecting tube 201. How the first connecting rod 5 is used for support is existing technology and will not be described in detail here.
[0028] The first connecting pipe 201 has sealing strips 4 extending along its length on both its upper and lower sides, and the second connecting pipe 202 has sealing strips 4 extending along its length on both its upper and lower sides. The sealing strips 4 on the first connecting pipe 201 and the sealing strips 4 on the second connecting pipe 202 abut against each other. The first connecting pipe 201 and the second connecting pipe 202 are square pipes with a width and thickness of 20mm.
[0029] In this embodiment, the sealing strip 4 on the top surface of the mounting bracket abuts end to end to reduce the gap between the sealing strips 4 on the top surface of the mounting bracket, thereby reducing the possibility of smoke leakage; the sealing strip 4 on the bottom surface of the mounting bracket abuts end to end to reduce the gap between the sealing strips 4 on the bottom surface of the mounting bracket, thereby reducing the possibility of smoke leakage.
[0030] The four corners of the connecting cylinder 1 are chamfered. The connecting cylinder 1 is made of 1.5mm thick galvanized sheet.
[0031] In this embodiment, the chamfer is provided to facilitate the upward insertion of the connecting cylinder 1 into the first flue 6 or the downward insertion of the connecting cylinder 1 into the second flue 7. The chamfer is a prior art feature and will not be elaborated upon here.
[0032] A connecting plate 3 is connected to the chamfered part of the connecting cylinder 1. The two sides of the connecting plate 3 are connected to the first connecting pipe 201 and the second connecting pipe 202 respectively. The connecting plate 3 is in the shape of a three-star.
[0033] In this embodiment, the connecting plate 3 is used to make the entire device structure more stable.
[0034] Working principle: The second flue 7 is placed into the pre-set channel, and the bottom end of the connecting tube 1 is inserted downward into the second flue 7. Then, the connecting rod 5 in the first connecting pipe 201 is cast into the building to fix the position of the first connecting pipe 201. Then, the first flue 6 is placed into the channel and moved downward until the top of the first flue 6 is inserted into the first flue 6.
[0035] Under the action of gravity, the first flue 6 presses down on the connecting plate 3 above the mounting frame, and the sealing strip 4 seals the gap between the first flue 6 and the top surface of the mounting frame. The sealing strip 4 also seals the gap between the second flue 7 and the bottom surface of the mounting frame, thus completing the seal in the horizontal direction and preventing smoke leakage.
[0036] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
