Soundproof and rainproof louver
The invention relates to the technical field of draught fans, in particular to a soundproof and rainproof louver. The soundproof and rainproof louver comprises a frame and slats, the parallel slats are arranged in the frame, each slat is formed by fixedly connecting an air inlet end slat body and an air outlet end slat body in a crossed mode, and an inner cavity of each slat is filled with sound absorption cotton. The soundproof and rainproof louver is characterized in that the two ends of each slat are fixedly connected with the frame, the height of each air inlet end slat body is one half that of each air outlet end slat body, the periphery of each air outlet end slat body is coated with a perforated plate, the upper end face and side face of each air inlet end slat body are coated with a rain shielding plate, the lower end face of each air inlet end slat body is provided with a lower perforated plate, the upper end of each rain shielding plate is fixedly connected with the upper end face of the corresponding air outlet end slat body through a transition arc face, and the lower end of each rain shielding plate is fixedly connected with the corresponding perforated plate through an arc convex face. By the adoption of the structure, the soundproof and rainproof louver has the advantages of being simple in structure, compact in appearance, low in weight, small in resistance, soundproof, rainproof, capable of absorbing sound and the like.
