1. A pneumatic therapy apparatus comprising a wrap and a controller:
wherein the wrap includes an outer wrap, an inner component housing, and an inner air bladder set;
wherein the controller is detachably connected to or separately connected to an outer surface of the outer wrap;
wherein the controller is connected directly, and detachably or separably to the inner component housing, the inner component housing is partially hidden inside the outer wrap and partially exposed outside the outer wrap, and the inner component housing contains an inflation motor and an integrated control board;
wherein the inflation motor is controlled by the integrated control board;
wherein the inner air bladder set includes one set or more than one set of a first air bladder and a second air bladder that are overlapped;
wherein a size of the first air bladder is bigger than that of the second air bladder, and the second air bladder is welded and located outside a lower section of the first air bladder;
wherein a boundary of the first air bladder is seal welded with one or more than one air flow hole on the lower section of the first air bladder, and a boundary of the second air bladder is seal welded on the lower section of the first air bladder, making the second air bladder cover the one or more than one air flow hole on the first air bladder;
wherein the one or more than one air flow hole on the lower section of the first air bladder creates one or more than one air flow passageway between the first air bladder and the second air bladder;
wherein there is a flow nozzle directly connected to the second air bladder without any part of the flow nozzle going through the first air bladder for the inflation motor to inflate the second air bladder first and then the first air bladder; wherein through the one or more than one air flow passageway, air flow enters the first air bladder from the second air bladder to achieve overlapped compression between the first air bladder and the second air bladder;
wherein the second air bladder is located on a side of the first air bladder that is farther away from a human body while using, and the second air bladder is completely overlapped on the side of the first air bladder;
the controller is outside the wrap;
the inner air bladder set is adjacent to the inner component housing;
the outer wrap is between the controller and the inner component housing directly or indirectly;
wherein the inner component housing contains a valve; and
the wrap includes an external patch outside to provide hot/warm and/or cold/cool.
