1. An inflatable product having a built-in air pump assembly and an inflatable chamber, the built-in air pump assembly comprising:
a casing defining an accommodating chamber;
a main air pump disposed in the accommodating chamber;
an air pressure adjustment assembly comprising:
a housing disposed in the accommodating chamber;
a flexible board dividing an interior of the housing into a first chamber in fluid communication with the inflatable chamber and a second chamber in fluid communication with an exterior of the inflatable chamber;
an adjusting device comprising:
a positioning component disposed in the second chamber; and
an electrically conductive elastic member disposed between the positioning component and the flexible board, one end of the elastic member being restrained by the positioning component; and
a driving device coupled to the positioning component and configured to drive the positioning component to move relative to the housing to thereby adjust the distance between the positioning component and the flexible board;
a first conductive element fixed to the positioning component; and
a second conductive element fixed to the flexible board;
wherein the first conductive element and the elastic member are, in response to a change in an internal air pressure of the inflatable chamber, moved into contact with the second conductive element and separated from the second conductive element.
