By setting the outer diameter of the sealing ring 5 to be larger than the inner diameter of the air duct 2, the outside of the sealing ring 5 can be in contact with the inner wall of the air duct 2, so that the sealing ring 5 can seal the air duct 2.

[0029] Specifically, by placing the airbag bag 4 inside the air duct 2, the gas in the accumulator body 1 flows into the airbag bag 4 through the air port 12, so that the airbag bag 4 can be expanded to fit the inner wall of the air duct 2, thereby achieving a sealing and leak-proof effect. With the help of the setting of multiple sealing rings 5, the airbag bag 4 can be limited and separated into multiple levels at the same time, thereby achieving the purpose of multi-level sealing to ensure airtightness.
