The bottom surface of the airtight bag 2 is tightly attached to the bag body 1 by the attaching or high-temperature pressing technology, so that the bottom of the airtight bag 2 is prevented from deforming to waste the inner space of the bag body 1 when air is pumped, and no gap is reserved between the airtight zipper 22 and the airtight bag 2, so that good airtight effect and waterproof effect are achieved.
In some embodiments, the inner layer is made of one of TPU, PVC, or rubber and the outer layer is made of one of Coodura, polyester fiber, or ballistic nylon cloth.
TPU, PVC and rubber all possess good air tightness, wear resistance and water resistance, and TPU materials are preferred, TPU has higher wear resistance than PVC and rubber, which means that the TPU can bear more friction and is not easy to damage, and the TPU is very important for vacuum pumping backpacks which need long-term use. The coodola, the polyester fiber or the ballistic nylon cloth have good wear resistance, the cost of the polyester fiber is relatively low, and the polyester fiber is preferred from the aspect of production cost.
In some embodiments, a vacuum pumping backpack further comprises a micro pump, wherein the micro pump is provided with an air inlet, the air inlet is communicated with the one-way exhaust valve 21, the micro pump is used for exhausting air in the airtight bag 2, and the micro pump is installed on the airtight bag 2 or the backpack body 1.
