[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a composite atmosphere-controlled fresh-keeping device for seafood comprises a box body 1, a box cover 2 and an atmosphere-controlled mechanism.

[0024] The box cover 2 is rotatably hinged to the box body 1 through a hinge 21. A magnet structure is provided on the box cover 2 and the box body 1. Specifically, the magnet structure is a magnet 11 provided on the box body 1 and an iron sheet provided on the box cover 2. The box cover 2 is detachably magnetically attracted to the box body 1 through the magnet structure. Through the above-mentioned hinge and magnet structure, the box cover 2 can be opened and closed on the box body 1.

[0025] At least two storage compartments 3 are arranged on the box body 1. In this embodiment, four storage compartments 3 are arranged on the box body 1. When the box cover 2 is closed on the box body 1, the box cover 2 forms an independent sealed space with each storage compartment 3, so that each storage compartment 3 is independent and not connected. In order to improve the sealing performance of the storage compartment 3, a sealing ring 12 is arranged between the box cover 2 and each storage compartment 3, and the sealing ring 12 fills the gap between the box cover 2 and the storage compartment 3 to achieve sealing.

[0026] The box cover 2 is rotatably hinged with a compartment cover 4 at a position corresponding to each storage compartment 3 through a hinge 22, and a magnet structure is provided on the box cover 2 and the compartment cover 4. The magnet structure is a magnet 23 provided on the box cover 2 and an iron sheet provided on the compartment cover 4. The compartment cover 4 is magnetically attracted to the box cover 2 in a detachable manner through the magnet structure. Through the above-mentioned hinge and magnet structure, the compartment cover 4 can be opened and closed on the box cover 2, and the corresponding storage compartment 3 can be opened and closed separately through the opening and closing of the compartment cover 4. In addition, a sealing ring 24 is provided between the compartment cover 4 and the box cover 2, and the gap between the compartment cover 4 and the box cover 2 is filled by the sealing ring 24 to achieve sealing.
