Abstract
An air pump includes a first sheet, a second sheet, an inflation valve and a check valve. The second sheet is directly connected to the first sheet so as to form a chamber. The inflation valve is provided on the chamber to lead air into the chamber when the chamber is extended. The check valve is also provided on the chamber to discharge the air in the chamber when the chamber is compressed. The air pump can be built in an inflatable product.
