Embodiment 1,

The embodiment discloses a waterproof shutter capable of quickly replacing dustproof cotton, which comprises a shutter body 1, wherein the shutter body 1 comprises a window frame 13 and shutter blades 11 transversely arranged in the window frame 13, as shown in fig. 1;

as shown in fig. 4 and 5, the cross section of the louver 11 has an elongated S-shaped structure including an inclined surface 11a and bent portions 11b reversely symmetrical at both ends of the inclined surface. The high end of inclined plane is located the inboard, combines the kink simultaneously, can play effectual waterproof effect. In addition, a plurality of louver blades 11 are distributed at equal intervals according to a proper distance, labyrinth passages 12 are formed between adjacent louver blades, and the labyrinth-like shape has a good protection effect on raindrops in a free falling state or raindrops with a certain angle with the vertical plane, namely, water drops are prevented from entering the inner side of the louver; unless the water source is flushed inwardly at an angle parallel to the inclined plane of the louver blades, this condition is not within the scope of the present embodiment as a human vandalism.

And the labyrinth channels formed between the adjacent louver blades can keep internal and external communication while being waterproof, so that ventilation of the inner side and the outer side of the louver can be ensured.

Therefore, for the waterproof shutter with the dustproof cotton capable of being replaced quickly disclosed by the embodiment, the shutter can have a good ventilation effect while being waterproof by setting the shutter blade structure with a specific shape.

Embodiment II,

The embodiment discloses a waterproof shutter capable of quickly replacing dustproof cotton, and on the basis of the shutter structure disclosed in the first embodiment, as shown in fig. 2, 3, 6 and 7, a slot structure 14 is formed on the back of a window frame 13; the dustproof cotton 2 and the pressing plate 3 are sequentially inserted into the slot structure 14, the dustproof cotton 2 is located at the inner side air inlet of the shutter blade 11, and the pressing plate 3 presses the dustproof cotton 2.

Wherein, dustproof cotton 2 installs between tripe blade and clamp plate 3, hugs closely the inboard air intake of individual tripe, has fine blocking effect to the dust that gets into from the air intake, and dustproof cotton adopts the air filtration cotton that does not influence ventilation effect to ensure not influence the normal circulation of air.

The back of the shutter window frame 13 is formed with a slot structure suitable for the insertion of dustproof cotton and a pressing plate, and is specifically provided with: as shown in fig. 6 and 7, the back of the window frame 13 is fixed with three turning plates 131 and one straight plate 132, and the three turning plates 131 and one straight plate 132 are enclosed into a circle and form a slot structure 14 together; wherein, the position of the straight plate 132 forms the opening position of the slot structure 14, and the dustproof cotton 2 and the pressing plate 3 are installed in the slot structure 14 at the back of the shutter in an inserting way from the opening position. The opening position of the slot is not limited to the top in the drawing, but may be provided at the side or bottom of the window blind frame.

Further, in order to enable the pressing plate 3 and the dustproof cotton 2 to be tightly fixed in the slot structure, as shown in fig. 6 and 7, a fixing hole 15 is formed in any folding plate 131, a nut 4 is welded at the fixing hole 15, and the nut 4 is connected with a bolt 5 in a matching manner. The bolt is pressed against the pressing plate 3 from the back by the nut 4, so that the dustproof cotton 2 is tightly attached to the inner air inlets of the shutters.
