<p>The present invention relates to an air umbrella device. The air umbrella device comprises: an air intake tube which is vertically arranged on the ground and includes an air intake hole on an upper part thereof; a water collecting tube which is arranged to accommodate the air intake tube therein concentrically to the air intake tube and includes a water guide tube formed on an upper part thereof to guide rain or snow downward; an exhaust gas tube which is arranged to accommodate the water collecting tube therein concentrically to the water collecting tube and includes an exhaust gas guiding tube coupled to an upper part thereof to guide air to the outside; a connection tube which is coupled to the lower parts of the air intake tube, the water collecting tube, and the exhaust gas and connects the air intake tube with the exhaust gas tube; and an air blower which is arranged between the exhaust gas tube and the water collecting tube and sucks the air through the air intake tube and exhausts the air through the exhaust tube. The air umbrella device can block rain and snow from falling to the lower part of the exhaust gas guiding tube by allowing the air exhausted through the exhaust air guiding tube to form an air film of a predetermined area on an upper part of the exhaust gas guiding tube.</p> |
