[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] A detachable steel wire frame irregular-shaped flexible air duct, as shown in the reference Figure 1-3 ,include:

[0027] The frame 1 has multiple sets, and these frames 1 can form a complete frame at both ends of the flexible duct. Frame 1 serves as the end support structure for the flexible duct, providing a stable boundary for the entire duct. Its shape is designed according to the irregular requirements of the flexible duct, and multiple frames 1 can cooperate to form irregular ports that meet usage needs. Simultaneously, the frame 1 has multiple mounting holes 11, which are equally spaced. These mounting holes 11 facilitate the connection and fixation of the flexible duct to other equipment or pipes, improving installation convenience and stability. Furthermore, the end faces of the multiple frames 1 are horizontal, and the vertical projection of the end faces of the multiple frames 1 is on the end face of the bottommost frame 1. This design ensures that during use, the upper frames 1 receive stable support from the lower frames 1, resulting in neater and more stable stacking, facilitating transportation and storage.

[0028] Connecting fabric 2 is used to connect two corresponding frame pieces 1 in the same group. Multiple connecting fabrics 2 are connected end-to-end via Velcro 5 and zippers 6. After connection, multiple frame pieces 1 automatically form a complete frame. The zipper 6 is located inside the Velcro 5, and the Velcro 5 seals the zipper 6, facilitating the replacement of parts of the structure and avoiding the need for complete replacement. Connecting fabric 2, as the main flexible part of the flexible duct, realizes the connection and spatial transition between frame pieces 1. The dual connection method of Velcro 5 and zipper 6 facilitates quick assembly and disassembly of the flexible duct while ensuring the sealing of the connection points. The zipper 6 provides a reliable fastening connection, while the outer Velcro 5 not only assists in fixing but also seals and protects the zipper 6, preventing dust and debris from entering the gaps and affecting its use. It also further enhances the sealing effect of the connection points, preventing air leakage.

[0029] Multiple steel wires 3 are provided and evenly distributed on the inner or outer side of the connecting fabric 2. The shape of the steel wires 3 is the same as the shape of the corresponding frame 1. The steel wires 3 serve as the skeleton of the flexible duct, providing necessary support strength to maintain its shape stability during use and prevent deformation or collapse. The even distribution of the steel wires 3 ensures uniform stress distribution throughout the flexible duct, improving overall support performance. Simultaneously, the shape of the steel wires 3 matches the shape of the frame 1, ensuring continuity and consistency in the shape of the flexible duct from its ends to its main body, meeting the special shape requirements of irregularly shaped flexible ducts. Furthermore, the steel wires 3 are evenly distributed at equal intervals on the connecting fabric 2, and are located at the center of the adhesive strip 4. This arrangement allows the steel wires 3 to better perform their supporting function and ensures the stability of their fixation on the connecting fabric 2.

[0030] Multiple adhesive strips 4 are evenly distributed and fixedly connected to the connecting fabric 2 to wrap the steel wire 3. The adhesive strips 4 secure the steel wire 3 to the connecting fabric 2, preventing it from shifting or puncturing the fabric, while also providing some protection and extending its service life. The adhesive strips 4 are elongated and longer than the steel wire 3, and are heat-sealed to the connecting fabric 2. The elongated shape and greater length of the adhesive strips 4 allow them to completely wrap the steel wire 3, and the heat-sealing method ensures a firm connection between the adhesive strips 4 and the connecting fabric 2, preventing detachment and guaranteeing the reliability of the steel wire 3's fixation.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
