[0033] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention.

[0034] Example 1
[0035] Embodiment 1 of this application provides a highly airtight flexible and rigid module airtight connector. This connector enhances the airtightness of the connection between the flexible and rigid modules, allowing highly elastic silicone and non-deformable rigid components to be tightly bonded, ensuring the airtightness and fastness of the pneumatic silicone.
[0036] The highly sealed flexible and rigid module airtight connector includes interface component 1 (2) and interface component 2 (3). During silicone injection, silicone component 1 and interface component 2 naturally interlock. Silicone component 1 has a cuboid or cylindrical structure, and its connection point fits tightly with the outer surface of interface component 2, achieving a seamless, leak-proof connection. Interface component 1 (2) and interface component 2 (3) can be quickly connected via plugging and unplugging. Both interface component 1 (2) and interface component 2 (3) are made of PLA material. Interface component 2 mainly consists of an enlarged section, a connecting section, and a gas channel. The enlarged section is used to connect with silicone component 1, and the connecting section is used to connect with interface component 3. The enlarged section and the connecting section are welded together. Gas channels are provided inside the enlarged section and the connecting section. The outer diameter of the enlarged section near silicone component 1 is larger than the outer diameter away from silicone component 1. The design of the interface being wider inside and narrower outside enhances the airtightness of the interface in the direction perpendicular to the air intake. The texture on the outer surface of the enlarged section increases the contact area between the interface component and the silicone component, thereby enhancing the tightness of the connection. The end of the enlarged section near silicone component 1 has a double-ring structure, with connecting ribs between the double rings to ensure free airflow during inflation and deflation while also providing structural strength. The connecting section has an annular groove, which engages with the annular protrusion of interface component 3 to achieve a plug-in connection. The gas channel has a funnel-shaped structure, with a conical funnel located inside the enlarged section and a funnel handle located inside the connecting section with its end extending beyond the connecting section. The part of the funnel handle extending beyond the connecting section extends into interface component 3. Interface component 2 3 is a circular tube structure. Interface component 2 3 has an annular protrusion and a channel for the funnel handle to pass through at one end near interface component 1 2.
[0037] Example 2
[0038] Embodiment 2 of this application provides a method for manufacturing and installing a highly airtight flexible and rigid modular ventilable connector, comprising the following steps:
[0039] S1, Interface component 1 2 and Interface component 2 3 for 3D printing PLA material; wherein Interface component 1 2 consists of an enlarged section, a connecting section and a gas channel, and the connecting section is provided with an annular groove; wherein Interface component 2 3 is provided with an annular protrusion;
[0040] S2, 3D printed silicone injection mold, the silicone injection mold has cavities for fixing interface component 2, so that it can be tightly connected with the interface component;
[0041] S3. Fix the enlarged section of interface component 2 into the cavity reserved in the silicone injection mold;
[0042] S4. Pour silicone into the assembled mold, ensuring that the silicone is in full contact with the outer surface of the enlarged section of interface component 2.
[0043] S5. After the silicone has cured, demold and remove the mold. At this time, silicone component 1 and interface component 2 will naturally snap together.
[0044] S6. Pass the gas passage of interface component 2 through the hole of interface component 3, and connect interface component 2 and interface component 3 through the annular groove and annular protrusion.
[0045] The connector of this invention is suitable for most manufacturing processes, including but not limited to CNC machining and 3D printing.
[0046] Example 3
[0047] The structure of this invention is easily expandable and can be connected to other expansion components to achieve combined control of the inflation structure.
[0048] Based on the existing dimensions of the flexible structure, the dimensions of the interface components are designed to ensure a tight connection with the flexible structure. Then, the fabricated interface component one is fastened to the flexible structure, allowing the flexible material to seamlessly enclose the enlarged section of interface component one. The connecting section of interface component one is then inserted into interface component two. Interface component two is then connected to an inflation / deflation control device, enabling inflation or deflation of the flexible structure through the interface components. Alternatively, multiple flexible pneumatic structures can be connected to individual interface components, and then these multiple interface components are connected to a main pipeline. Each interface component two can be fitted with a partition plate, and the opening or closing of the partition plate controls the continuity of each interface component. Finally, the main pipeline is connected to an inflation / deflation control device, achieving combined control of multiple flexible pneumatic structures.
