Abstract

An inflatable knapsack comprises a back body which comprises a bag body to form a knapsack with an accommodating space. the back body comprises a second gas chamber; two ends of the second gas chamberrespectively extend outward with waistband structures; a first gas chamber with a gas pump and two ends of the first gas chamber extend outward with strap structures; an air channel which is betweenthe first gas chamber and the second gas chamber; a switch member; and a control module which is electrically connected with the switch member and the gas pump; by turning on the switching element, the enabling signal is transmitted to the control module, and the control module energizes the gas pump according to the enabling signal, so that the gas permeates the gas pump to inflate the strap structure by the first air chamber; the gas enters the second air chamber from the air channel, and is inflated with the waistband structure.
