Claim:
A multi-sectional air enclosure, comprising: two outer films, folded together vertically; an inner film, disposed between the two outer films and one surface thereof being spread with a heat resistant material; an air filling passageway, disposed between the two outer films and used for allowing outside air to be filled in; a plurality of air cylinders, disposed side by side beside the air filling passageway and adhered to form between the two outer films by means of hot sealing, each air cylinder being adhered to form a plurality of air chambers in series by means of hot sealing; at least one air inlet, formed between the inner film and one of the outer films by not adhering the inner film to another film by means of hot sealing and used for communicating the air filling passageway with the air cylinder; a plurality of air passageways, connected to the air inlets and formed between the inner film and one of the outer films by not adhering the inner film to another film by means of hot sealing; a plurality of branch air passageways, communicating with the air passageway and formed between the inner film and one of the outer films by not adhering the inner film to another film by means of hot sealing; and a plurality of openings, positioned on the inner film, each opening being positioned at an end of each branch air passageway; wherein, outside air in the air filling passageway flows into the plurality of branch air passageways via the air passageway and is filled into each air chamber via each opening to allow the air chamber to be filled with air and inflated, and the air in the air chamber thrusts the air passageway to cause the air to be locked.
