The cover body 103 is rotatably connected to the main body 101 through the support rod 104 and is used to close the opening of the packaging cavity 102. The sealing component includes a first magnetic monomer 105 connected to the main body 101 and arranged around the open edge of the packaging cavity 102, and a second magnetic monomer 106 connected to the cover body 103 and used for mutual magnetic attraction with the first magnetic monomer 105. The first magnetic monomer 105 and the second magnetic monomer 106 are both magnetic steels that can generate magnetism after being energized. The sealing component also includes a power supply element that is electrically connected to the first magnetic monomer 105 and the second magnetic monomer 106 respectively.
