By welding both the inner edge and the outer edge of the gasket 20 to the air duct 100, the sealing performance between the gasket 20 and the air duct 100 can be ensured, and at the same time, the gasket 20 can be stably fixed to the air duct 100. By using continuous welding, the weld formed by the connection welding is continuous from beginning to end, which can ensure the strength and stability of the welding position and also provide better sealing performance.

[0062] In order to be able to distinguish the installation position of the marine kitchen maintenance structure on the surface of the air duct 100 after wrapping the protective layer, the protective layer includes a first protective layer and a second protective layer. The first protective layer wraps the air duct 100, and the second protective layer wraps the marine kitchen air duct maintenance structure. By using two protective layers to separately wrap the air duct 100 and the marine kitchen air duct maintenance structure, the installation position of the marine kitchen air duct maintenance structure can be distinguished after wrapping, which is convenient for maintenance.
