AIR-PURIFYING DUST-COLLECTING DEVICE, STREETLIGHT FOR AIR-PURIFYING DUST-COLLECTING DEVICE, AND TRAFFIC LIGHT FOR AIR-PURIFYING DUST-COLLECTING DEVICE

摘要

The present invention provides an air-purifying dust-collecting device, a streetlight for the air-purifying dust-collecting device, and a traffic light for the air-purifying dust-collecting device, which comprise: a pipe-shaped body having a channel part formed therein; a first suction part formed in the body and formed at the channel part to allow air to be introduced therethrough so as to generate an ascending air current; a first dust-collecting part formed at an upper side of the body to have a cross-section area larger than that of the body so as to reduce the flow velocity of the air having been introduced through the first suction part; and a discharge part, which is formed above the first dust-collecting part, includes a fan rotatable by an external wind, and is configured to be able to discharge the air by using the fan.
