As shown in fig. 1, in the present embodiment, the bent side of the first flange 101 is connected to one end of the first straight side 102, the first flange 101 is connected to the first straight side 102 in a right angle relationship, and the first straight side 102 is parallel to the vertical side of the window blind frame 2, and in other embodiments, the angle relationship between the first flange 101 and the first straight side 102 may be an acute angle or an obtuse angle, which determines whether water drops, dust, and foreign substances can be blocked by the first flange 101. The other end of the first straight edge 102 is connected to one end of the connecting portion 103, and the connection angle relationship is an obtuse angle, and determines whether water drops, dust, and foreign substances blocked by the first folding edge 101 are guided to the connecting portion 103 by the first leg 102 and can be guided to the outside by the connecting portion 103. The other end of the connecting portion 103 is connected to one end of a second straight edge 104, the second straight edge 104 is parallel to the vertical side of the window blind frame 2, the other end of the second straight edge 104 is connected to a second folded edge 105, the second folded edge 105 and the second straight edge 104 form an obtuse angle, and water drops, dust and impurities can be guided from the second straight edge 104 to the second folded edge 105 and then fall from the edge of the second folded edge 105.

Specifically, referring to fig. 2, fig. 2 is a schematic side view of a louver of a dustproof louver according to an embodiment of the present disclosure, and a right side of the view is a portion of the louver facing the outside. When water drops, dust and impurities enter the louver, the water drops, the dust and the impurities can contact the second straight edge 104, the second folded edge 105, the connecting part 103 and the first straight edge 102 in the louver blade 1 under the normal condition, and when the water drops, the dust and the impurities contact the second straight edge 104, the water drops, the dust and the impurities are blocked and vertically fall to the ground; when the water drops, dust and impurities contact the second folded edge 105, they will continue to move forward along the second folded edge 105 until they hit and are blocked by the first straight edge 102 or the connecting portion 103 in the other louver blade 1 at the lower end, slide down by the slope of the connecting portion 103 and fall vertically to the ground; when the water drops, dust and impurities contact the connecting part 103, the water drops, dust and impurities move to the first straight edge 102 along the connecting part 103 due to inertia, then impact on the first straight edge 102 and are blocked by the first straight edge 102, and then slide down by the gradient of the connecting part 103 and vertically fall to the ground; when the water drops, dust and impurities contact the first straight edge 102, they will be blocked by the first straight edge 102 and slide down by the slope of the connecting portion 103 and fall vertically to the ground. In special cases, such as bad weather conditions like sand storm, heavy rain, etc., the water drops, dust and impurities may reach the inside through the path of the connecting portion 103, the first straight edge 102, the first folded edge 101, and at this time, the water drops, dust and impurities will be blocked by the second straight edge 104 of the upper end blade of the blind blade 1, guided to the connecting portion 103 along the second folded edge 105 of the upper end blade, slide down by the slope of the connecting portion 103 and fall vertically to the ground. In addition, the straight line formed by the edge point of the first folding edge 101 and the edge point of the second folding edge 105 is parallel to the vertical edge of the window frame of the blind, which is designed to fix the shape of the air channel uniformly and simultaneously to enable water drops, dust and impurities to be removed from the blind more quickly.

Referring to fig. 4, fig. 4 is a schematic view illustrating a dust-proof screen structure of a dust-proof blind according to an embodiment of the present disclosure, where the dust-proof screen structure includes a fixing member 3, a rotating buckle 4, a limiting member 5, a dust-proof screen 6, a fixing rivet 7, and filter cotton (not released). In this embodiment, the dust screen structure faces the inside, the limiting member 5 and the fixing member 3 are both fixed on the window frame 2 of the window shutter, the dust screen 6 is installed in the inner groove of the window frame 2 of the window shutter, the dust screen 6 is a dust screen in the prior art and can intercept foreign matters, and the rotating buckle 4 is rotatably installed at the edge of the dust screen 6. When a large wind blows from the outside of the blind, the limiting member 5 can prevent the dust screen 6 from escaping into the inside, and the limiting member 5 can be any component capable of limiting the position movement of the dust screen, in this embodiment, one limiting member 5 is respectively arranged above and below the edge of the window frame 2 of the blind. The rotating buckle 4 is installed at the edge of the dust screen 6, and in this embodiment, the height of the rotating buckle is the same as that of the limiting member 5, and there are 2 same rotating buckles. The fixing member 3 has the same height as the rotating buckle 4 and the limiting member 5, and is a fixing member in the prior art, and when the rotating buckle 4 rotates toward the fixing member 3, the rotating buckle 4 and the fixing member 3 are fixed together, that is, the dust screen 6 and the rotating buckle 4 are fixed, the fixing member 3 and the window frame 2 are fixed, and the fixing of the rotating buckle 4 and the fixing member 3 represents that the dust screen 6 and the window frame 2 are fixed together. The fixing rivet 7 fixes the fixing piece 3 on the window frame 2 of the shutter. The filter cotton tightly covers on the dust screen and is tiled and arranged in the inner groove of the window frame 2 of the shutter. Because of the relationship between the rotary buckle 4 and the fixing part 3, when the rotary buckle 4 is separated from the fixing part 3, the dust screen 6 can be drawn out from the position of the rotary buckle 4, so as to achieve the purpose of replacing the dust screen 6 or replacing the filter cotton tightly attached to the dust screen.

It should be added that the connection mode between the first folding edge 101 and the first straight edge 102, the first straight edge 102 and the connection portion 103, the connection portion 103 and the second straight edge 104, and the second straight edge 104 and the second folding edge 105 is a seamless tight connection, if the connection mode is not tight, the ventilation efficiency is reduced, and water drops, dust and impurities cannot be completely blocked outside the louver.
