[0021] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 A soft bag sealing interface structure, comprising a connector 1 and a cover 2. The outer side of the connector 1 is provided with external threads, and the inner side wall of the cover 2 is provided with internal threads. The connector 1 and the cover 2 are connected by the threaded connection of the external threads and the internal threads. This connection method not only facilitates the operation of the user, but also ensures the stability and sealing of the connection.

[0022] A sealing ring 3 is arranged on the top inner side of the cover 2. A groove 4 is formed between the sealing ring 3 and the cover 2. The side of the sealing ring 3 close to the cover 2 is an arc-shaped protruding structure 5. The top of the structure can be embedded into the groove 4. When the connector 1 is embedded, it is pressed tightly to one side of the cover 2 by the counterforce of the arc-shaped protruding structure 5, forming a tight sealing contact, thereby further enhancing the sealing performance. In order to ensure the stability and durability of the sealing ring 3, the sealing ring 3 and the cover 2 are integrally formed. The arc-shaped protruding structure 5 is hollow inside and can be deformed to adapt to the pressure change when the connector 1 is embedded.
