[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0016] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "install," "connect," "connect," and "assemble" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0017] Reference Figure 1 A vacuum backpack includes a bag body 1, a shoulder strap and a handle, and is characterized in that it includes an airtight bag 2, the bag body 1 is provided with a accommodating cavity 11, the accommodating cavity 11 is used to accommodate luggage, the airtight bag 2 is arranged in the accommodating cavity 11, the airtight bag 2 is provided with a one-way exhaust valve 21 and an airtight zipper 22, the airtight bag 2 includes an inner layer and an outer layer, the outer layer is a wear-resistant material, and the inner layer is a sealing material.

[0018] By setting the airtight bag 2 as a double-layer structure including an inner layer and an outer layer, the outer layer is made of wear-resistant material and the inner layer is made of sealing material, the sealing effect is better than that of the existing vacuum pumping backpack; by setting the airtight bag 2 in the accommodating cavity, the airtight bag 2 is protected; by setting a one-way exhaust valve 21 on the airtight bag 2, a one-way exhaust effect is achieved, and by setting an airtight zipper 22 on the airtight bag 2, a sealing effect is achieved; the problem that the existing vacuum pumping backpack is easily damaged after long-term use, resulting in air leakage and affecting the compression effect is solved.

[0019] In some embodiments, the bottom surface of the airtight bag 2 is fixedly connected to the package body 1 by laminating or high-temperature pressing, and the airtight zipper 22 is fixedly connected to the airtight bag 2 by laminating or high-temperature pressing.

[0020] Through the bonding or high-temperature pressing technology, on the one hand, the bottom surface of the airtight bag 2 is tightly fitted to the package body 1 to prevent the bottom of the airtight bag 2 from deforming when the air is evacuated, resulting in waste of the internal space of the package body 1; on the other hand, it ensures that there is no gap between the airtight zipper 22 and the airtight bag 2, thereby achieving good airtight and waterproof effects.

[0021] In some embodiments, the inner layer is made of one of TPU, PVC, or rubber; and the outer layer is made of one of Cordura, polyester, or ballistic nylon.

[0022] TPU, PVC, and rubber all offer excellent airtightness, abrasion resistance, and water resistance. TPU is the preferred material because it has higher abrasion resistance than PVC and rubber, meaning it can withstand more friction without damage, which is crucial for vacuum backpacks that require long-term use. Cordura, polyester, or ballistic nylon all offer excellent abrasion resistance. Polyester is relatively inexpensive, making it the preferred material for production costs.

[0023] In some embodiments, a vacuum backpack also includes a micro vacuum pump, which is provided with an air inlet connected to a one-way exhaust valve 21. The micro vacuum pump is used to discharge the gas in the airtight bag 2. The micro vacuum pump is installed in the airtight bag 2 or the bag body 1.

[0024] When exhausting the airtight bag 2, it is usually done by directly squeezing the airtight bag 2 manually. This method is labor-intensive, inconvenient to use, and can easily damage the airtight bag 2, and the vacuuming effect is poor. Alternatively, an external exhaust device is used to exhaust the airtight bag 2. This method needs to be used in conjunction with an external exhaust device that is independent of the package 1, which is inconvenient to use. By setting up a micro vacuum pump and connecting the air inlet of the micro vacuum pump to the one-way exhaust valve 21, it is ensured that the airtight bag 2 will only be exhausted when the micro vacuum pump is needed to exhaust air. When the micro vacuum pump is turned off, the one-way exhaust valve 21 can prevent outside air from re-entering the airtight bag 2, thereby maintaining the vacuum state in the airtight bag 2, avoiding the problem of manual squeezing of the airtight bag 2, which causes damage to the airtight bag 2, and poor vacuuming effect. Installing the micro vacuum pump on the airtight bag 2 or the package 1 makes the exhaust process more convenient.

[0025] Preferably, the micro vacuum pump is an electromagnetic vacuum pump, an electromagnetic diaphragm pump, an electromagnetic piston vacuum pump or an electromagnetic vortex pump.

[0026] The micro vacuum pump extracts air from the airtight bag 2, creating a certain vacuum state, thereby further enhancing the sealing of the airtight bag 2, ensuring that the items inside are not affected by moisture, reducing the space occupied by luggage, and facilitating the carrying and storage of luggage. In other embodiments, the micro vacuum pump can also be other devices that can extract the gas from the airtight bag 2.

[0027] In some embodiments, a hard flat plate is provided on the top of the airtight bag 2 .

[0028] The hard surface protects the airtight bag 2 and the luggage inside it, preventing any luggage outside the bag from damaging it. It also flattens the top of the evacuated bag, making it easier to store luggage outside the bag, such as tablets, laptops, and other electronic devices. The hard surface is made of plastic or lightweight metal.

[0029] In some embodiments, there are 1 to 4 airtight bags 2 .

[0030] Preferably, two airtight bags 2 are provided. The two airtight bags 2 can meet the luggage classification needs of most users and facilitate the degassing operation of the airtight bags 2 .

[0031] In some embodiments, the package 1 is provided with an electrically connected solar panel and a battery, the battery is electrically connected to the micro air pump, and the battery is provided with a bidirectional interface for charging and discharging.

[0032] A solar panel is located on the outside of the backpack. The panel is flexible and adapts to the backpack's curves and folds. The panel converts solar energy into electricity, which is stored in a battery. The battery powers the micro-vacuum pump, which can also be powered by an external power source when the battery is low. A bidirectional interface not only allows the battery to be charged from an external power source, but also allows the battery to serve as a mobile power source for other external devices. The combination of the solar panel and battery allows the airtight bag 2 to operate normally even when away from a power source, reducing reliance on traditional power sources, contributing to energy conservation and emissions reduction, and aligning with the concept of sustainable development.

[0033] Preferably, an air pressure sensing component is provided in the airtight bag 2, and the air pressure sensing component includes an electrically connected microcontroller and an air pressure sensor. The battery is electrically connected to the microcontroller and the air pressure sensor respectively. The air pressure sensor is used to detect the air pressure. The microcontroller is electrically connected to the micro air pump. The microcontroller is used to read the data from the air pressure sensor and process the data. When it is detected that the air pressure in the airtight bag 2 reaches a preset value, a command is sent to control the micro air pump to stop pumping air.

[0034] When the air pressure in the airtight bag 2 reaches a preset value, the system automatically stops pumping air to prevent damage to the bag or items due to excessive pumping.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
