[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] In the description of the present utility model, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] The present utility model provides an air leakage-proof and heat-insulating air duct, which includes an air duct body 1, a waterproof and wind-proof zipper 2, and a cover edge structure 3. Among them, two adjacent air duct bodies 1 are connected by the waterproof and wind-proof zipper 2, and the cover edge structure 3 covers the waterproof and wind-proof zipper 2 and the cut edge of the air duct body 1 and is tightly connected. The air leakage-proof and heat-insulating air duct provided by the present utility model has two adjacent air duct bodies 1 connected by the waterproof and wind-proof zipper 2. The waterproof and wind-proof zipper 2 has the functions of waterproof and wind-proof, and also has good wear resistance and tensile strength, ensuring the long-term use of the air leakage-proof and heat-insulating air duct. At the same time, the cover edge structure 3 is used to cover the waterproof and wind-proof zipper 2 and the cut edge of the air duct body 1, thereby further covering the air leakage and rain leakage parts, and effectively blocking the air leakage and water leakage phenomenon, solving the technical problem that small pinholes may appear at the cut pieces of the connection of the composite heat-insulating air duct in the prior art, resulting in serious air leakage.

[0026] As an optional implementation manner, the air duct body 1 and the waterproof and wind-proof zipper 2 are adhesively connected by hot melt adhesive, making the connection between the air duct body 1 and the waterproof and wind-proof zipper 2 more firm. The hot melt adhesive has high adhesive strength and aging resistance, and can maintain stable connection performance when the air leakage-proof and heat-insulating air duct is vibrated or the temperature changes.

[0027] As an alternative implementation, between the edge covering structure 3 and the waterproof and windproof zipper 2, and at the trimmed edge of the edge covering structure 3 and the air duct body 1, they are connected by Velcro. The Velcro has good adhesiveness, which can ensure the tight fit between the edge covering structure 3 and the waterproof and windproof zipper 2, and prevent air leakage at the connection of the air duct body 1.

[0028] As an alternative implementation, the cross-sectional shape of the air duct body 1 can be circular or oval.

[0029] As an alternative implementation, there is a print, that is, color printing, on the outer wall of the air duct body 1, which increases the aesthetic degree of the air duct body 1.

[0030] As an alternative implementation, the air duct body 1 includes a wire mesh layer and a support layer. The air duct body 1 adopts special wire mesh forming and support forming processes, so that while maintaining aesthetics, the air duct body 1 has good strength and stability. This process also helps to reduce deformation and damage of the air duct body 1 during the production process.

[0031] As an alternative implementation, it further includes a connecting edge covering 4. The connecting edge covering 4 is adhesively bonded to the side wall of the air duct body 1. The connecting edge covering 4 is used to connect two air duct bodies 1, and the length direction of the connecting edge covering 4 is the same as the length direction of the air duct body 1.

[0032] In summary, through the upgrading of the aesthetic shape, wire mesh forming, support forming, waterproof and windproof zipper, the combination of the edge covering structure and Velcro, and the application of the hot melt adhesive process, the airtight and heat-insulating air duct of the present utility model effectively solves the problems existing in the traditional composite heat-insulating air duct, and realizes an aesthetic, efficient, convenient and airtight heat-insulating air duct.

[0033] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
