This structure allows the bag body 1 to have a large liquid capacity and be stable upright. The liquid supply assembly 2 includes a joint 3 and a seal cover 4, the joint 3 having a liquid supply hole 31 formed therein, and a side wall at the top end of the bag body 1. The sealing cover 4 is fixed to the bag body 1, and the sealing cover 4 is detachably connected to the joint 3 so as to seal the communication between the bag body 1 and the outside world. Preferably, the sealing cover 4 and the joint 3 are screwed together, which has a simple structure and makes it easy to inject liquid into the bag body 1 multiple times. At least one elastic belt 5 is provided on each side of the bag body 1, and both ends of the elastic belt 5 are connected to the upper and lower ends of the bag body 1 respectively, which combine to form a convenient backpack structure that frees up both hands and is easy to carry, significantly improving comfort and convenience in use and optimizing the user experience.

[0015] Specifically, as shown in Figures 1 to 3, in this embodiment, movable latches 6 are provided on both ends of the elastic belt 5, and connecting rings 7 connected to the movable latches 6 are provided on the bag body 1. The elastic belt 5 can be attached and detached as needed, and when in use, only one elastic belt 5 is used, and is connected to the connecting rings 7 on both sides of the upper end of the bag body 1 via the movable latches 6, and when combined, they form a one-shoulder structure that is easy to carry.
