[0002] A backpack refers to a bag that is carried on the back. It is made of a variety of materials, including leather, plastic, polyester, canvas, nylon, cotton and linen. It is also divided into many types according to the type of use. Among them, outdoor backpacks such as mountaineering bags, travel bags, ordinary school bags and daily backpacks have different characteristics according to different usage scenarios.

[0003] The existing outdoor backpacks generally have greater wear resistance to ensure that they are not easily damaged by friction and collision when used outdoors. At the same time, outdoor use often requires carrying more items, so the load-bearing performance will generally be improved. At the same time, in order to protect the user from being squeezed by the straps or feeling uncomfortable on the shoulders when bearing a large load, the backpack generally adds air cushions or air bags to make the straps softer and reduce the force on the user's shoulders. In addition, due to the weight of the backpack, the backpack fits the user's back when carried, which may cause the back to be too stuffy in hot weather. Therefore, the prior art also provides some air bags so that there is a gap between the back of the backpack to accommodate gas circulation. However, this arrangement is still insufficient. Carrying the backpack for a long time outdoors still causes insufficient ventilation of the back and sweat to get hot on the back. Therefore, a new solution is proposed to enhance the ventilation effect of the back of the backpack. Utility Model Content
