Description

Technical Field

[0001] This utility model relates to the field of flexible air duct technology, and in particular to a completely non-combustible glass wool flexible air duct. Background Technology

[0002] Flexible ducts are pipes made of flexible materials that are corrosion-resistant, airtight, and resistant to mold, and are mainly used in air conditioning systems.

[0003] Existing flexible ducts, although their overall structure is flexible, have been processed into fixed duct shapes such as circles. This structure occupies a large area during transportation, which is not conducive to transportation. At the same time, when assembling and using multiple ducts, external accessories and tools are required, which is very inconvenient to use.

[0004] To address the aforementioned issues, this application proposes a completely non-combustible glass wool flexible duct. Utility Model Content

[0005] This invention provides a completely non-combustible glass wool flexible duct to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a completely non-combustible glass wool flexible air duct, including an air duct body. The air duct body is composed of a glass wool insulation layer, an outer glass fiber layer, and an inner glass fiber layer. The glass wool insulation layer is located between the outer glass fiber layer and the inner glass fiber layer. A U-shaped edging is fixedly fitted at the edge of the air duct body. A first zipper and a second zipper are fixedly connected to the front and rear sides of the air duct body, respectively. A third zipper and a fourth zipper are fixedly connected to the left and right sides of the air duct body, respectively.

[0007] Preferably, multiple fixing seams are sewn onto the main body of the air duct, and the glass wool insulation layer, the outer glass fiber layer, and the inner glass fiber layer are connected by the fixing seams.

[0008] Preferably, the outer surface of the duct body is fixedly connected with multiple perforated webbing.

[0009] Preferably, a sealing strip is fixedly connected to the top front side of the duct body, and a male hook and loop fastener and a female hook and loop fastener are respectively sewn and fixed to the outer surfaces of both ends of the sealing strip.

[0010] Compared with related technologies, the completely non-combustible glass wool flexible air duct provided by this utility model has the following beneficial effects:

[0011] The duct body, composed of a glass wool insulation layer, an outer glass fiber layer, and an inner glass fiber layer, is completely non-combustible. Furthermore, with the third and fourth zippers, the originally flat duct body can be assembled into round or oval ducts. The flat duct body before assembly is easy to transport, and the assembled duct does not affect normal use. Multiple duct bodies can also be connected and assembled using the first and second zippers without the need for external accessories or tools, making it very convenient to use.

[0016] Implementation examples, by Figure 1-3 The present invention includes a duct body 1, which is composed of a glass wool insulation layer 11, an outer glass fiber layer 12, and an inner glass fiber layer 13. The glass wool insulation layer 11 is located between the outer glass fiber layer 12 and the inner glass fiber layer 13. A U-shaped edging 15 is fixedly fitted at the edge of the duct body 1. A first zipper 4 and a second zipper 5 are fixedly connected to the front and rear sides of the duct body 1, respectively. A third zipper 6 and a fourth zipper 7 are fixedly connected to the left and right sides of the duct body 1, respectively. The duct body 1 can be rolled up and connected together to form a circular or flat circular duct through the third zipper 6 and the fourth zipper 7. Multiple rolled-up duct bodies 1 can be connected together through the first zipper 4 and the second zipper 5.

[0017] Multiple fixing seams 14 are sewn onto the duct body 1. The glass wool insulation layer 11, the outer glass fiber 12, and the inner glass fiber 13 are sewn together by the fixing seams 14. The fixing seams 14 can sew the glass wool insulation layer 11, the outer glass fiber 12, and the inner glass fiber 13 that make up the duct body 1 together. After the duct body 1 is rolled up and formed, the outer glass fiber 12 and the inner glass fiber 13 are located on the outside and inside of the glass wool insulation layer 11, respectively.

[0018] Multiple perforated webbing 2 are fixedly connected to the outer surface of the duct body 1. The perforated webbing 2 facilitates the installation and fixation of the rolled-up duct body 1.

[0019] A sealing strip 3 is fixedly connected to the top front side of the duct body 1. The outer surfaces of the two ends of the sealing strip 3 are respectively sewn and fixed with a male hook and loop fastener 31 and a female hook and loop fastener 32. When the duct body 1 is rolled up and formed and multiple duct bodies 1 are connected and assembled, the sealing strip 3 can wrap the connection between the two duct bodies 1 inside and connect the two ends of the sealing strip 3 together through the male hook and loop fastener 31 and the female hook and loop fastener 32. An end seal 8 can be installed at the end of the duct formed by the combination of multiple duct bodies 1, and the end seal 8 is also located inside the sealing strip 3 and wrapped.

[0020] Working principle:

[0021] Before assembly, the duct body 1 is flat. When in use, the duct body 1 can be rolled up and connected to each other by the third zipper 6 and the fourth zipper 7 to form a circular or flat circular duct. Multiple rolled-up duct bodies 1 can be assembled. During assembly, they are mainly connected to each other by the first zipper 4 and the second zipper 5. Then, the connection between two duct bodies 1 is wrapped with a sealing strip 3, and the two ends of the sealing strip 3 are glued and fixed by the female Velcro 31 and the female Velcro 32. At the same time, an end seal 8 can be installed on the last duct body 1 for sealing. The end seal 8 is also wrapped by the sealing strip 3 on the duct body 1.
