The main points are that the travel backpack also comprises a first liner arranged inside the backpack body, wherein a first chamber is formed by the first liner and the back of the backpack body; a first air bag arranged inside the first chamber; a second liner arranged inside the backpack body, wherein a second chamber is formed by the second liner and the bottom of the backpack body; a second air bag disposed inside the second chamber; a third liner disposed inside the backpack body, wherein a third chamber is formed by the third liner and the side portion of the backpack body; a third air bag disposed inside the third chamber; an inflation handle with an unidirectional inverted valve; and an air escape valve. Moreover, the first air bag is communicated with the inflation handle via a first air pipe, the second air bag is communicated with the inflation handle via a second air pipe, and the third air bag is communicated with the inflation handle via a third air pipe. The technical effects are that the travel backpack which has a simple structure, is convenient to use and occupies less space effectively enables articles in the backpack from being thoroughly wet once falling into water or is prevented from directly sinking into the bottom of the water, such that travelers can have fun without any worries.
