When the vane 2 is opened, the first fulcrum plate 21 can only rotate upward, and the second fulcrum plate 22 can only rotate downward. The width of the first support plate 21 is greater than that of the second support plate 22, so that when there is an air pressure difference between the two sides of the blind, the stress on the first support plate 21 is greater than that on the second support plate 22, so that the vanes 2 can be always in the closed state.

The weight of the first plate 21 is also greater than the weight of the second plate 22. When the vane 2 is closed, the first fulcrum plate 21 is positioned below the second fulcrum plate 22, and therefore, the first fulcrum plate 21 can be automatically closed under the effect of its own weight.
