Rain-proof unpowered ventilation device
The invention discloses a rain-proof unpowered ventilation device. The device comprises an unpowered ventilation cowl and a rain-proof barrel which are connected mutually. Openings are formed in the upper and lower ends of the rain-proof barrel correspondingly. The opening in the upper end of the rain-proof barrel is connected with the unpowered ventilation cowl. An expanding tube with the outer diameter larger than those of the two ends of the rain-proof barrel is arranged in the middle of the rain-proof barrel. A rain-proof cone and a drainage pipe are fixedly connected into the expanding tube. An opening of the rain-proof cone faces the unpowered ventilation cowl and at least covers the opening in the upper end of the rain-proof barrel. One end of the drainage pipe communicates with thebottom of the rain-proof cone, and the other end of the drainage pipe penetrates downwards out of the rain-proof barrel. According to the rain-proof unpowered ventilation device provided by the invention, by arranging the rain-proof barrel on the lower side of the unpowered ventilation cowl, accordingly, rainwater entering the unpowered ventilation cowl can be collected and drained outwards, andthe rainwater is prevented from entering a ventilation pipeline in a room through the unpowered ventilation cowl. Meanwhile, by arranging a filter net in the rain-proof barrel, external dust can be isolated, and at the same time, insects and the like outside can also be isolated.
本发明公开了一种防雨型无动力换气装置，包括相互连接的无动力风帽和防雨筒，防雨筒的上下两端设置有开口，防雨筒上端的开口与无动力风帽连接，防雨筒的中部设置有一外径大于两端的扩大筒，扩大筒内固接有一防雨锥和排水管，防雨锥的开口朝向无动力风帽且至少覆盖防雨筒上端的开口，排水管的一端与防雨锥的底部连通，另一端向下贯穿至防雨筒外。本发明的通过在无动力风帽的下侧设置防雨筒，从而可以将进入无动力风帽内的雨水收集向外排放，避免雨水通过无动力风帽进入室内的换气管路。同时，通过在防雨筒内设置过滤网，可以隔离外部粉尘，同时也可隔离外部的昆虫等。
