A female buckle 940 is fixedly installed on the left side of the straps 910, and a male buckle 930 is fixedly installed on the right side of the straps 910. The male buckle 930 and the female buckle 940 are connected to each other. Through the connection of the male buckle 930 and the female buckle 940, the straps 910 pull the lumbar support sponge block 500 to fit snugly and wrap around the waist of the human body. At the same time, the back straps 920 are the back straps of a schoolbag. When carrying a schoolbag, the back straps 920 also pull the upper part of the lumbar support sponge block 500 to fit snugly against the waist of the human body, making the lumbar support sponge block 500 more effective in supporting the waist.

[0034] The working principle of this utility model is as follows: a fabric layer 200 is wrapped around the base plate 100, and the fabric layer 200 is circumferentially sewn onto the back of the backpack. Sponge block 300, sponge block 400 and waist support sponge block 500 are provided on both sides of the front end of the fabric layer 200. The sponge block 300, sponge block 400 and waist support sponge block 500 are sewn onto the fabric layer 200 through a mesh fabric layer 600.

[0035] The heat dissipation vent pipe 800 is fixedly installed on the base plate 100 through the fixing head 820, and the connecting head 840 is connected to the hose. The micro air pump and power bank can be directly put into the backpack. By starting the micro air pump, the gas is injected into the heat dissipation vent pipe 800 through the hose and then discharged from the through hole 830, thereby accelerating the gas flow inside the gap channel 700 and improving the heat dissipation effect on the back of the human body.
