The periphery of the first cover is equipped with a sealing ring which can effectively seal against the periphery of the material port, thereby ensuring that the vacuum state inside the storage bin is not destroyed, preventing the entry of external air and moisture, and prolonging the shelf life of the stored material. The lighting assembly is arranged on the side of the first cover away from the storage bin, which can provide additional light source for the storage bin when needed, especially in low light environment, so that the user can clearly observe the material in the storage bin. This design not only ensures the sealing and aesthetics of the storage bin, but also improves the user experience, making it more efficient and convenient in actual application.

[0010] In some embodiments, the first cover is a transparent cover. The transparent cover allows the user to clearly observe the material state in the storage bin, without the need to open the lid to know the remaining amount and quality of the stored material in real time. This design not only improves the convenience of use, but also effectively reduces the damage to the vacuum state caused by frequent opening of the lid, thereby better maintaining the vacuum environment in the storage bin and prolonging the shelf life of the material.

[0011] In some embodiments, the side of the first cover away from the storage bin is formed with a mounting groove, and the lighting assembly is arranged in the mounting groove. The side of the first cover away from the storage bin is formed with a mounting groove, which provides a special space for the installation of the lighting assembly. The lighting assembly is arranged in the mounting groove, which can effectively hide the lighting device while ensuring its functionality, avoiding the safety hazards that may be caused by exposed wires and components, and not affecting the overall appearance. Such design not only makes the installation of the lighting assembly more stable and avoids damage caused by external environment, but also makes the lighting effect more concentrated and effective.

The arrangement of the second cover can provide protection for the mounting slot and the lighting assembly inside, prevent the intrusion of dust, dirt or other external objects, and prolong the service life of the lighting assembly. The cover design can also make the product appearance more neat, reduce visual interference, and make the entire storage barrel look more beautiful and modern. In addition, the second cover can also serve as an additional functional component, for example, it can be designed in a detachable form to facilitate users to conveniently replace or maintain the lighting assembly when needed without having to disassemble the entire cover. The flexibility of this design improves the user experience and makes the product more user-friendly during use.

[0013] In some embodiments, the lighting assembly comprises a circuit board and a light-emitting component electrically connected to the circuit board, and the cover further comprises a button embedded in the second cover and connected to the circuit board, the button being used for operation to control the on-off of the light-emitting component. The arrangement of the button allows users to conveniently control the on-off of the lighting assembly. Users can quickly turn on or off the light-emitting component by simply pressing the button, improving the convenience of use. The electrical connection between the circuit board and the light-emitting component means that users can achieve more intelligent control through the button, such as setting different brightness modes or flashing modes, further improving the functionality of the lighting assembly.

[0014] In some embodiments, the second cover is a non-transparent cover, and an opening is formed in the second cover, through which the storage bin can be observed through the first cover.
