An external one-way exhaust valve is arranged on the outer surface of the corrugated sealed air bag, and the corrugated sealed air bag is connected with the outside through the external one-way exhaust valve. A handle is arranged on the surface of the corrugated sealed air bag. This design has a reasonable structure and a compression function. There is no need to carry an additional vacuuming tool. It is easy to use and meets people's needs.

[0004] Since the outer layer of this type of backpack is made of cloth as a storage layer, after the internal gas is discharged through the external one-way exhaust valve, external gas will slowly enter the backpack after long-term use. If the backpack is carried for a long time, the gas in the bag needs to be extracted regularly, and the final use effect is not good.

[0005] Based on the above problems, there is an urgent need for a backpack that can extract the gas in the bag without the need to regularly use a one-way exhaust valve, and can remain in a vacuum state during long-term use. Summary of the invention

[0006] In view of the fact that the current vacuum backpack cannot be kept in a vacuum state for a long time, the present invention provides a vacuum backpack with a sterilization function to solve the above problem.

At the same time, discharging the air can prevent the growth of bacteria on the clothes in the storage air-evacuation bag. In addition, an elastic sensing component is arranged in the storage air-evacuation bag in the backpack. As the backpack is used for a long time, air enters the backpack, and the atmospheric pressure in the backpack is constant with that outside. The pressure sensed by the elastic part decreases, and the single-chip microcomputer senses the decrease in pressure signal, so as to control the exhaust pump to exhaust again, and the storage air-evacuation bag can be automatically exhausted without manual operation.

[0015] Further preferably, the single chip microcomputer and the exhaust pump perform wireless communication via Bluetooth.

[0016] Adopting the above technical solution: Since the single-chip microcomputer and the elastic sensing device are both arranged on the inner side of the storage vacuum bag, the use of connecting wires can easily cause air to enter the storage vacuum bag.

[0032] See also Figure 1-3, like the original vacuum pumping backpack 1, only a one-way exhaust valve 3 is set on the backpack 1. When in use, the gas in the backpack is discharged to the outside of the backpack through the one-way exhaust valve 3, thereby reducing the space occupied by items in the backpack. However, during the long-term use of the backpack, other external items can slowly penetrate into it, and the backpack needs to be opened regularly to exhaust the gas, which is not convenient to use. Based on the above problems, the embodiment of the present application discloses a vacuum pumping backpack 1 with a sterilization function, including a backpack 1, a storage pumping bag 2 is set inside the backpack 1, and the storage pumping bag 2 is provided with a one-way exhaust valve 3 and an airtight zipper 4.

The elastic sensing component 6 includes an elastic member 7 and an elastic force sensing device 8 arranged on the surface of the elastic member 7. The elastic force sensing device 8 is electrically connected to a single-chip microcomputer 9. The single-chip microcomputer 9 is used to send a control command to the exhaust pump 5 for exhaust. During the exhaust process of the exhaust pump 5, the storage vacuum bag 2 will apply a squeezing force to the elastic member 7. The elastic force sensing device 8 senses the pressure and transmits it to the single-chip microcomputer 9. The single-chip microcomputer 9 determines the leakage of the storage vacuum bag 2 according to the pressure signal, and thus sends a control command to the exhaust pump 5 for exhaust. It is worth mentioning that in the above scheme, a one-way exhaust valve 3 is arranged on the storage air-evacuation bag 2 in the backpack 1. After the items are placed in the storage air-evacuation bag 2, the air in the storage air-evacuation bag 2 can be exhausted through the one-way exhaust valve 3, which can save space. At the same time, exhausting the air can prevent the growth of bacteria on the clothes in the storage air-evacuation bag 2. In addition, an elastic sensing component 6 is arranged in the storage air-evacuation bag 2 in the backpack. When the exhaust pump 5 evacuates the backpack, the internal air pressure will be continuously reduced, thereby providing a force to squeeze the elastic member 7, and the elastic force sensing device 8 on the elastic member 7 can The elastic force is sensed and the elastic force signal is continuously transmitted to the single-chip microcomputer 9. When the backpack is used for a long time, external gas will penetrate into the backpack, and the atmospheric pressure inside the backpack will gradually become constant with the external pressure. The pressure applied to the elastic member 7 is reduced, and the elastic force of the elastic member 7 on the elastic force sensing device 8 is also reduced accordingly. The single-chip microcomputer 9 receives the sensing signal of the elastic force sensing device 8 which is smaller than the threshold value set by its program, and can generate a control command signal to send to the exhaust pump 5.

The above scheme can sense the arrangement of the stored items. When the heights of items in different parts of the storage air-evacuation bag 2 are different, it is easy to cause gaps in the schoolbag, resulting in air residue. The present design can sense the storage status of the schoolbag and sound an alarm. The operator can adjust the items in the storage air-evacuation bag 2.
