[0006] Preferably: An anti-string zipper extension layer is installed on the outer side wall of the rear panel.

[0007] Preferably: A zipper pocket storage is installed on the front side end face of the front panel, and a waterproof zipper bag is arranged below the zipper pocket storage.

[0008] Preferably: An anti-string zipper layer is installed on the front inner side end face of the front panel.

[0009] Preferably: A breathable mesh layer is installed on the rear side end face of the rear panel. On the left and right sides symmetrically behind the breathable mesh layer, woven belt shoulder straps are installed, and buckle inserts are installed on the rear side end faces of the woven belt shoulder straps.

[0010] Technical Effects and Advantages of the Utility Model

[0011] In the utility model, the vacuum bag and exhaust valve structure is adopted. By exhausting air manually or by machine, a vacuum compression effect is achieved, realizing a practical design with a small bag size and a large bag capacity, and meeting the needs of people on business trips and travels.

[0016] The following further describes the present utility model in detail with reference to the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0017] Please refer to Figures 1 to 3 , in this embodiment, an extended backpack with an in-built vacuum bag is provided, which includes a backpack body 1. The backpack body 1 includes a front panel 2 and a rear panel 3. The rear end face of the front panel 2 is chain-connected and installed with the rear panel 3 through a first zipper 4. A vacuum bag 5 is arranged on the front end face inside the rear panel 3. A sealing zipper head 6 is installed on the front end face of the vacuum bag 5. An exhaust valve 7 is arranged to the right of the sealing zipper head 6. During operation, the inner lining structure of the main bag of a conventional backpack is improved into a vacuum bag 5 design to store multiple amounts of clothes. Close the exhaust valve 7 and zip up the sealing zipper head 6, and then exhaust manually or by machine to achieve the vacuum compression effect, realizing the practical design of a small bag size with a large bag capacity and meeting the travel needs of people.

[0018] A reverse zipper extension layer 8 is installed on the outer side wall of the rear panel 3. During operation, open the extension layer zipper on the side to assist in increasing the capacity of the bag body and adding storage space to the inner main bag.

[0019] A zipper pocket storage 9 is installed on the front end face of the front panel 2, and a waterproof zipper pocket 10 is arranged below the zipper pocket storage 9.
