[0002] A backpack refers to a bag carried on the back, with diverse materials, such as genuine leather, plastic, polyester, canvas, nylon, cotton and linen texture suitcases. In the era of increasingly advocating individuality, various styles such as simple, retro, and cartoon also meet the needs of fashionable people to show off their individuality from different aspects. The styles of suitcases have also expanded from traditional business bags, schoolbags, and travel bags to pen cases, coin purses, small sachets, etc.

[0003] At present, by setting a support pad, bamboo slices or jade slices on the back of the backpack, the human back and the back of the backpack do not come into complete contact, and the human back can dissipate heat through the breathable gaps, so that the user will not feel stuffy when carrying the backpack. For example, a comfortable backpack disclosed in Chinese Patent Publication No. CN207803745U. However, when the user carries the backpack, the air flow speed at the breathable gaps is often slow, resulting in the inability of the hot air between the human back and the backpack to dissipate quickly, so that the user still feels stuffy when carrying the backpack.
