Air umbrella device

An air umbrella apparatus comprising:

• an air suction pipe vertically disposed on a ground and having a suction hole formed in an upper end thereof, into which outside air is suctioned;
• a water collection pipe disposed concentrically with the air suction pipe so as to accommodate the air suction pipe therein, a water-collection-inducing pipe being coupled to an upper end of the water collection pipe so as to guide rain or snow inward;
• an exhaust pipe disposed concentrically with the water collection pipe so as to accommodate the water collection pipe therein, an exhaust-guiding pipe being coupled to an upper end of the exhaust pipe so as to guide inside air outward;
• a communication pipe accommodated in the water collection pipe and coupled to a lower end of the air suction pipe so as to move the outside air that has passed through the air suction pipe to a space between the water collection pipe and the exhaust pipe;
• a blower rotatably provided at a lower side of the exhaust pipe so as to form an air stream so that the outside air is introduced through the air suction pipe, and thereafter the inside air is exhausted through the exhaust-guiding pipe;
• an air guiding unit disposed between the blower and the water collection pipe and configured to guide the inside air that has passed through the blower to a space between the exhaust-guiding pipe and the water-collection-inducing pipe;
• and
• a dehumidification unit provided between a bottom surface of the exhaust pipe and the blower and configured to remove moisture contained in the outside air introduced into the exhaust pipe,
• wherein the inside air exhausted through the exhaust-guiding pipe forms an air curtain having a predetermined area at an upper side of the exhaust-guiding pipe, thereby preventing the rain and snow from falling from the exhaust-guiding pipe.
