[0002] Schoolbags refer to bags made of cloth, leather, etc. Students use them to carry textbooks and stationery. According to the change of consumers' aesthetic taste, schoolbags have developed into a kind of schoolbag that can reduce students' burden - luggage. The materials of luggage are more diverse. Leather, PU, ​​polyester, canvas, cotton and linen, etc. Luggage keeps up with fashion trends. At the same time, in an era where individuality is increasingly flaunted, various styles such as simplicity, retro, and cartoon also cater to the needs of fashion people to show their individuality from different aspects.

[0003] The current back pad structure of school bags is an integrated fixed structure, which makes it impossible to disassemble and replace. The bubble pad uses a mesh cover to cover the sponge inside, which makes the support insufficient and forms a situation of squeezing the soft couch, making the school bag uncomfortable to carry. In addition, when the back is attached to the side of the bubble pad, the soft couch causes the exhaust to be not smooth, resulting in excessive temperature of the back affecting the comfort. Utility Model Content

[0006] A school bag TPU bubble pad comprises a main breathable outer isolation layer, inner side edges of the main breathable outer isolation layer are evenly provided with inner support sponge layers, sides between the inner support sponge layers are provided with exhaust channels, and inner side edges of the inner support sponge layers are fixedly provided with porous support inner pad sponge elements.

[0007] As a preferred embodiment of the present utility model: the main breathable outer isolation layer is made of high wear-resistant material, and the main breathable outer isolation layer is arranged with an inner hollow mesh structure, the number of the main breathable outer isolation layers is two, and the specifications and dimensions of the two main breathable outer isolation layers are kept consistent, and the main breathable outer isolation layer has memory shaping properties.

[0008] As a preferred embodiment of the present invention: the number of the inner supporting sponge layers is eight, and the eight inner supporting sponge layers are arranged in a group of four in a straight line with each other on the inner side of the main breathable outer isolation layer, and the inner supporting sponge layers are made of porous and highly breathable sponge material.

[0009] As a preferred embodiment of the present utility model: the exhaust channels are arranged between the side edges of multiple inner supporting sponge layers and the inner side of the main breathable outer isolation layer, the interior of the exhaust channels is connected to the interior of the multiple inner supporting sponge layers, and the interior of the exhaust channels is connected to the hollow interior of the main breathable outer isolation layer.

[0010] As a preferred embodiment of the utility model: the number of the porous support inner pad sponge elements is set consistently with the number of the inner support sponge layer, the porous support inner pad sponge elements are made of highly supportive sponge materials, and the porous support inner pad sponge elements are arranged in a filling state on the inner side of the inner support sponge layer, the inner side of the porous support inner pad sponge elements is arranged in a multi-granular state, and the internal particles of the porous support inner pad sponge elements are arranged in a polygonal shape, and the particles are butt-jointed with each other to leave gap structures at the corners.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model arranges two main breathable outer isolation layers symmetrically and plug-in inside the back mounting bag of the school bag, and seals and fixes the opening through the zipper structure of the opening, so that the two main highly breathable outer isolation layers are fixedly installed. After the person carries the school bag, the side edges of the two main breathable outer isolation layers on the back are butt-jointed and arranged at the back position, and the position with a gap between the two main breathable outer isolation layers is arranged at the spine position of the back of the person, forming a hollow ventilation effect. The main breathable outer isolation layer adopts wear-resistant material, so that it is not easy to be damaged when rubbing against the back. At the same time, under the support of the internal inner supporting sponge layer, the school bag can squeeze the back to form a supporting and isolating effect, and the middle air of the back can be smoothly discharged through the exhaust grooves between the multiple inner supporting sponge layers. Under the support of the porous supporting inner pad sponge element, gaps are left between the particles, so that the temperature of the back can be further exhausted, thereby forming a cooling effect on the temperature of the back. The split multi-piece structure is adopted, which makes it more convenient to install and use. At the same time, the combination of multiple breathable gap structures makes the exhaust and cooling effects better when used. BRIEF DESCRIPTION OF THE DRAWINGS
