The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

FIG. 1 is a perspective view showing a state in which the air umbrella device 100 according to the present invention is installed to block the eyes, FIG. 2 is an exploded perspective view of the air umbrella device 100 according to the present invention, And FIG. 3 is a cross-sectional view illustrating the operation of the air umbrella apparatus 100.

As shown in the drawing, the air umbrella device 100 according to the present invention is constructed such that the air suction pipe 110, the collector pipe 120, and the exhaust pipe 130 are concentrically disposed one on the other. The air suction pipe 110 is disposed in the center and the collector pipe 120 is disposed to receive the air suction pipe 110 and the exhaust pipe 130 is disposed outside the air suction pipe 110. The air suction pipe 110 and the exhaust pipe 130 are connected to each other by a communicating pipe 140 so as to communicate with each other.

The air suction pipe 110 is vertically arranged to have a constant height from the ground. A suction head 111 for sucking air is provided at an upper portion of the air suction pipe 110. The suction head 111 is formed in a spherical or hemispherical shape. On the surface of the suction head 111, a plurality of suction holes 111a through which air is sucked are formed.

The air introduced into the suction head 111 is discharged to the atmosphere through the exhaust pipe 130 via the air suction pipe 110. The air suction pipe 110 and the suction head 111 may be integrally formed or separately detachably coupled.

The collector pipe 120 is formed to have a larger diameter than the air suction pipe 110. The water collecting pipe 120 is arranged to receive the air suction pipe 110 therein. The water collection tube 120 is vertically coupled to the upper portion of the communicating tube 140. The collecting water pipe 121 is formed at the upper part of the collecting water pipe 120 in the form of a trumpet tube having a gradually increasing diameter.

The collecting conduit 121 guides the snow or rain to the collecting pipe 120. The snow and rain flow into the water collecting pipe 120 along the inclined surface of the water collecting duct 121. The snow and rain flowing into the collector pipe 120 pass through the communicating pipe 140 and are moved to the lower portion and then to the water storage tank 160.

Here, the hot water heater 125 may be installed in the water collecting conduit 121. Thus, it is possible to prevent snow from being attached to the surface of the collecting duct 121 and freezing and blocking the path of the snow during the winter season. That is, in the winter season, the hot-wire heater 125 is driven to melt the snow on the surface of the collecting duct 121 and flow to the collector pipe 120.

The exhaust pipe 130 is disposed outside the collecting conduit 121. An exhaust guide pipe 131 is disposed at the upper part of the exhaust pipe 130 to guide the exhaust of air.

The exhaust pipe 130 discharges the air moved through the communicating pipe 140 to the atmosphere to form an air wall having a predetermined thickness. The snow or rain can be prevented from moving to the lower part by the air wall, and the shielding area L can be formed in the lower part of the exhaust guide pipe 131 to avoid snow and rain.

Here, it is preferable that the length of the exhaust guide pipe 131 is longer than the length of the collecting oil conduit 121 because the length of the air wall can be extended.

The collector pipe 120 and the exhaust pipe 130 may be formed of a synthetic resin such as plastic or a metal material.

The communication pipe 140 connects the air suction pipe 110 with the collector pipe 120 and the exhaust pipe 130 and connects the air flow path so that the air introduced into the air suction pipe 110 can be discharged to the exhaust pipe 130 .

3, the communicating tube 140 includes a communicating tube main body 141 disposed coaxially with the air suction tube 110, and a communicating tube body 141 extending from both sides of the communicating tube main body 141 and inserted through the collector tube 120, And an air flow pipe 145 connected to the air flow pipe 145.

The communicating tube body 141 is formed to have the same diameter as the air suction pipe 110. A suction pipe connecting hole 143 is formed through the communicating tube body 141. The communicating tube body 141 is disposed coaxially with the air suction pipe 110 so that air introduced into the air suction pipe 110 flows into the suction pipe connecting hole 143. The lower portion of the communicating tube body 141 is clogged so that all of the introduced air moves to the air moving tube 145.

The air moving pipe 145 extends through the side surface of the communicating pipe body 141 and is inserted through the lower portion of the collecting pipe 120. A first opening 123 is formed through the bottom of the collector pipe 120.

The air moving pipe 145 is inserted into the first opening 123 to transfer air to the exhaust pipe 130. At this time, the exhaust pipe connecting hole 145a at the end of the air moving pipe 145 is opened to supply air to the exhaust pipe 130.

The blower 150 is coupled to the space between the exhaust pipe 130 and the collector pipe 120 to apply a driving force for forced air movement. The blower 150 is formed in a ring shape surrounding the outer circumferential surface of the collector pipe 120, and a plurality of rotating blades 151 are formed along the circumferential direction.

Although not shown in the drawing, a bearing (not shown) is provided between the collector pipe 120 and the blower 150. A rotor (not shown) is provided inside the blowing pipe 150 and a driver (not shown) corresponding to a rotor (not shown) is provided in the collector pipe 120. As the power is supplied, the blower pipe 150 rotates about the bearing (not shown) while the rotor (not shown) rotates along the driver (not shown).

When the blower 150 is rotated, air flows through the air suction pipe 110 and air is discharged to the outside through the exhaust pipe 130 to form an air curtain.

Here, an inverter (not shown) may be further coupled to the blower 150. By the coupling of the inverter (not shown), the manager can rotate the blower 150 in the forward and reverse directions. The forward drive of the blower 150 functions as a air umbrella that shields the rain and the snow and the reverse drive is used to remove foreign substances on the surface of the air suction pipe 110 by discharging air to the air suction pipe 110 have.

The operation of the air umbrella apparatus of the present invention having such a configuration will be described with reference to Figs. 1 to 3. Fig.

For installation, the user arranges the air suction pipes 110, the collector pipes 120 and the exhaust pipes 130 having different diameters concentrically with each other and the communication pipe 140 at the bottom. The air suction pipe 110 is arranged coaxially with the communicating tube body 141 and fixed. The fastening can be done using a fastening member such as a bolt-nut or by welding.

Then, the air moving pipe 145 is inserted into the first opening 123 of the collector pipe 120 to be engaged.

A water tank 160 is provided below the ground on which the air umbrella apparatus 100 is installed to store snow and rain that have flowed into the water collector pipe 120.

When the rain and snow do not come, the blower 150 is kept in a state of not supplying power. In the event of sudden rain and snow, the manager supplies power to blower 150. Air is sucked into the air suction pipe 110 while the blower 150 rotates.

The air A sucked into the suction hole 111a of the suction head 111 is moved along the air suction pipe 110 as shown in FIG. Then, the air is introduced into the communicating tube body 141 and then moved to the exhaust pipe 130 along the air moving pipe 145. The air is moved upward from the exhaust pipe 130 and then discharged obliquely into the atmosphere along the exhaust guide pipe 131.

At this time, the discharged air is discharged to a thickness equal to the space between the exhaust pipe 130 and the collector pipe 120, and an air film is formed. The snow and rain falling into the air film due to the pressure of the air film are guided to the collector pipe 120 side and moved.

That is, at the upper portion of the collecting pipe 120, a low-pressure inhaler intestine as much as the amount of the air introduced into the inside through the air suction pipe occurs. Accordingly, when the air or rain reaches the inside of the air membrane, it is bent toward the low pressure suction pipe formed by the water collecting conduit 121 and guided to the collector pipe 120 by gravity, And a shielding region L is formed on the lower side to protect against exposure to rain or snow.

Thereby, a blocking region L is formed in the lower portion of the exhaust guide pipe 131 where the air film is formed. The pedestrian can stop at the lower portion of the exhaust guide pipe 131 to avoid rain and snow when it rains.

At this time, if the rotating speed of the blower 150 is increased or decreased to increase the length of the air film, the area of the blocking region L may be increased. In addition, the rotational speed of the blower 150 can be increased or decreased according to the amount of snow and the amount of snow.

On the other hand, the rain and snow that have flowed into the collector pipe 120 are moved downward and then stored in the water storage tank 160.

The air umbrella device of the present invention is an air film formed by suction and discharge of air without a separate shielding film, and forms a shielding region which is safe from rain and snow. As a result, it can be used as a place to evacuate visitors in case of a sudden rainy weather, and it can prevent snow damage by installing it on a plastic house or a soft roof.

In addition, when the air umbrella device of the present invention is installed in a stand of a soccer stadium or a bus stop in a city center, it is possible to safely avoid rain and snow without a separate umbrella.

Also, the rain and snow stored in the water tank can be collected in a clean state and reused in useful areas.

That is, as shown in Fig. 4 (a), the air umbrella is unfolded when it is used, and when not used, the upper portion is folded as shown in Fig. 4 (b). Accordingly, it is possible to prevent foreign matter from flowing into the air suction pipe 110 and the collector pipe 120 at the time of non-use.

For the folded structure, the exhaust guide pipe 135 of the exhaust pipe 130a is formed of a waterproof fiber such as an umbrella. Then, the vertical frame 137 is arranged at regular intervals, and the horizontal frame 137a is formed in the horizontal direction. The vertical frame 137 is folded inward about the horizontal frame 137a. That is, the vertical frame 137 is provided as a vertical link around the horizontal frame 137a.
