Description

Technical field

[0001] The invention relates to a ventilation device, in particular to a thin ventilation skylight (ventilator) used in various industrial plants. Background technique

[0002] At present, combined roof ventilation skylights are mostly used in natural ventilation equipment for high-heat workshops. This type of ventilation skylights are mainly composed of windshields, rain shields, flood panels and valve plates. However, the existing ventilation skylights are not only complicated in structure and heavy load, but the height of the ventilation skylights above the roof opening is also relatively high, so the wind resistance is not strong. In the case of relatively strong wind, there will also be rain caused by wind around the ventilation skylight. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a ventilation skylight with simple structure and strong wind resistance.

[0004] The technical problem to be solved ...
