摘要
An inflation device comprises an electrically-driven air pump, a rotary valve, two sets of air sacs, and a pressure control unit. The air sacs are connected with the rotary valve which is in turn connected with the air pump. The air sacs are kept in the state of periodic and alternate inflation and deflation. The magnitude of pressure of the compressed air from the air pump is detected by the pressure control unit so as to interrupt or resume the power supply to the air pump.
