Inflatable material structure, has hollow material with interior and exterior wall, where hydrophilic, humidity-storing glue layer is at inner wall and down-modular layer is at hydrophilic, humidity-storing glue layer

摘要

The structure has a hollow material (31) with an inner and an outer wall (312), where a hydrophilic and humidity-storing glue layer with low melting point is at the inner wall. The down-modular layer is at the hydrophilic and humidity-storing glue layer, which closely locks the cavity. An opening (37) for the air inlet and air outlet, is connected by the cavity to the hollow material which lets the air in and out.
