Background technique

With the changes in modern lifestyles and the rapid development of the logistics industry, many items are traded in the form of logistics, such as electronic products, chemical products, pharmaceutical products, ceramics, glass and other daily necessities, where they are stored or transported. In the process, it is inevitable that there will be crushing, collision, falling, etc., resulting in damage or deformation of the product, causing serious losses to people.

In order to protect the product, people will use a box or the like to package the product before storage or transportation, and provide a certain cushioning effect for the product to achieve the purpose of protection. At present, the commonly used packaging boxes include paper packaging boxes and inflatable packaging bags. The traditional paper packaging boxes do not provide a good cushioning effect and do not have a good protective effect. Therefore, in the process of use, it is often necessary to use foam first. Flexible plastics and the like are packaged in multiple layers and then placed in a package to achieve good anti-fall and anti-collision performance, but this undoubtedly increases the transportation cost, and is extremely inconvenient to package, which not only wastes time, but also reduces work efficiency. And increased labor costs, which are no longer in line with the needs of the modern transportation industry.

The air-filled packaging material achieves the cushioning effect by filling the film with gas, which can be inflated and put into use at the packaging site, so that it has the advantages of low transportation cost, easy storage, and better buffering performance than the conventional packaging material. Also conducive to environmental protection.

With the development of the packaging industry, inflatable packaging devices serve a wide variety of industries in a variety of industries. Markets and consumers are increasingly diversifying their needs for inflatable packaging devices. In order to ensure that the packaged article can be well protected by the air-packing device and to ensure a good appearance after being packaged, the developer of the air-packing device is dedicated to providing a suitable air-packing device for the packaged product having packaging requirements.

Therefore, it is necessary to invent a package which is capable of integrally packaging an electronic device and its accessories and enabling the electronic product and the accessory to have their own independent space. Thus, in a state where the electronic product is transported, stored, and the like, the electronic device and its accessories can be safely packaged in the respective spaces. When the electronic products need to be used together, there are cases where they can be conveniently connected together, and it is not possible to find a suitable accessory when using.

For a package such as a television or a computer monitor, it usually has some matching connecting accessories. At the same time, it has a large area such as a screen that is easily damaged. These accessories also have some parts that are vulnerable to damage. In order to avoid damage to the screen caused by the matching connection accessories, it is usually necessary to separately place these accessories in a space that can stably store and protect these accessories. In this way, the electronic product and its accessories will not cause damage to each other due to collision. At the same time, because many electronic products have a wide variety of accessories and need to be used together, these accessories should not be packaged separately with their accompanying electronic products. Therefore, the invention is an extremely important meaning of an air-packing device which enables an electronic product and its accessories to have independent packaging space and can be separately protected in different spaces of the same packaging device.
