That is, the air pipe 211 is preferably arranged in a form in which several common straws are bundled, and most of the wind moves through the air pipe 211 , and cannot pass through the air pipe 211 . Other winds are moved to the gap between the air pipe 211 and the air pipe 211 to be discharged.

On the other hand, as shown in Figs. 1 to 3, the outer side of the main body 200 extends with the inner space of the main body 200, and the external air can be sucked by the rotation of the impeller 240 to be described below. The inlet 220 is formed, and serves to allow external air to be sucked in.

Here, the suction port 220 is simply formed on both sides of the main body 200, and is formed to be long in the horizontal direction, so that even if the position of the impeller 240 to be described below is located in any part, air can be sucked from the outside. There is an effect that there is no restriction on the installation position of the impeller 240 at all.

In other words, as shown in FIG. 1, the suction ports 220 are formed in pairs at regular intervals on both sides of the main body 200, respectively, and the formed form is formed to be long in the horizontal direction as a whole, and if necessary Therefore, the suction port 220 is formed in one shape on both sides of the main body 200, and the upper and lower heights thereof are determined according to the position of the impeller 240 configured in the interior of the main body 200. It can also be configured.

In addition, a separate cover 250 can be configured on the outside of the main body 200 to prevent foreign substances from entering into the suction port 220 to prevent damage and damage to the impeller 240 . have.

The cover 250 may be formed of a mesh-like mesh as shown in FIG. 1 , and the holes may be formed in various sizes as needed.

In addition, although the cover 250 is illustrated as being configured to protrude slightly than the outside of the main body 200 as a whole in the present invention, the outside of the cover 250 is on the same line as the outside of the body 200 as necessary. It may be configured to be fitted in the suction port 220 so as to be disposed in the .

The outlet 230 is a configuration substantially formed at the uppermost end of the blower pipe 210 , and is not a separate configuration, but is formed in the blower pipe 210 .

That is, air is sucked in through the suction port 220 , and the wind generated through the impeller 240 is moved and discharged through the air pipe 211 of the blower pipe 210 , but is not moved to the air pipe 211 . An outlet 230 is formed so that the unsatisfactory winds are discharged.

At this time, as shown in FIG. 2 or FIG. 3 , the outlet 230 or the air pipe 231 is configured such that a part is disposed inside the discharge member 300 so that the wind blows through the outlet 230 or air. When discharged from the pipe 211, it is possible to discharge smoothly without resistance such as bumping.

As an example, as shown in FIG. 2 , the end of the air pipe 211 protrudes toward the discharge member 300 and is formed to have different lengths to be bent outwardly, so that the wind is rapidly and strongly discharged to the outside. can be

In other words, the end of the air pipe 211 is bent in the lateral direction from which the wind is finally discharged and positioned close to it.

The impeller 240 is configured in the interior of the main body 200, is configured in the lower portion of each blower pipe 210, and the arrangement is arranged on the same line as the suction port 220 on a horizontal line, the suction port ( 220) to generate wind through rotation, and is configured to be discharged through the outlet 230 and the air pipe 211 when the air is moved between the air pipe 211 and the air pipe 211.

Here, the impeller 240 is configured with a motor 241 operating through external power or a battery to rotate the impeller 240, and in the case of the battery, although not shown separately, the shape of the body 200 It can also be arranged in the lower inner part through deformation.

In addition, as shown in FIG. 1 or FIG. 2 , the impeller 240 has a pair of suction ports 220 on both outer side surfaces of the main body 200 , and is spaced apart from each other at regular intervals or in a horizontal direction in a form on both sides. As it is formed as a whole, it should be arranged at the same position on a vertical line, but it can be arranged at any position on a horizontal line, so there is no restriction on the installation position at all.

At this time, the impeller 240 generates wind by sucking air from the suction ports 220 on both sides of the main body 200 through rotation substantially as shown in FIG. 3 , and at this time, suction in different directions. In order to prevent the generated air from rubbing against each other, a partition wall 243 is formed in the central portion of the impeller 240 to prevent the sucked air and the generated wind from collide with each other.

On the other hand, the power supply unit 260 is a configuration for controlling the operation of the motor 241, it is possible to apply a button method, a slide method, and the like.

In this case, the power supply unit 260 may be selectively controlled by configuring a remote control capable of operating the power supply unit 260 at a short distance.

As described above, the blower pipe 210, the outlet 230, and the impeller 240 are each individually configured as a pair, and the inlet 220 is a pair of final four on both sides of the main body 200. Only one impeller 240 can be operated under the control of the power supply unit 260, each of the impellers 240 can be operated simultaneously, and the discharge member 300 is finally removed according to the operated impeller 240 The exhaust wind can be discharged from any direction at 180° or 360° above the horizon.

In addition, two or more impellers 240 are configured between the air pipe 211 and the suction port 220 , and may be arranged on different lines (zigzags) to amplify the suction power.

That is, a plurality of impellers 240 are constituted, but the impeller 240 except for the impeller 240 disposed closest to the blower pipe 210 is not connected to a separate blower pipe 210, and only wind can be generated. , it is preferable that the corresponding suction ports 220 are formed according to the number of the impellers 240 .

In addition, when the plurality of impellers 240 are configured, they may be rotated in the same direction or in different directions.

The discharge member 300 is a core component of the present invention, and as shown in FIGS. 1, 2, 3 and 5, may be coupled or fitted to the upper portion of the main body 200. As shown in FIGS.

More specifically, as shown in FIGS. 2, 3 and 6, one side is extended with the outlet 230, and the other side is discharged from the outlet 230 and discharged to the outside, so that it can be discharged in multiple directions. A flow path 310 and a partition plate 320 configured in the central portion of the flow path 310 so that the wind discharged from the outlet 230 can be uniformly distributed to the flow path 310 , It is configured to extend to the upper portion of the partition plate 320, and is composed of a horizontal induction part 330 for guiding the air flowing from the flow path 310 to move in a horizontal direction to discharge it.

2 or 3, the lower portion of the flow path 310 is a portion in which the wind discharged from the outlet 230 and the air pipe 211 is introduced, and the central portion serves as a passage through which the wind moves. And the other side direction of the outlet 230 and the air pipe 211 is a portion from which the wind is finally discharged to the outside.

At this time, the flow path 310 is formed such that one side is naturally curved through the shape of the horizontal induction part 330 as shown in FIG. 6 , and the discharge member 300 of the present invention is 180° in the horizontal direction or Since 360° should be able to be discharged in all directions, it can be formed of two or four, and in the present invention, it is shown that it is formed of four, and it is not limited as an embodiment of the present invention.

The partition plate 320 has a central portion protruding downward as shown in FIGS. 2, 3 and 6, so that the wind generated from each of the outlet 230 and the air pipe 211 does not collide with each other, It is configured such that the wind discharged to each flow path 310 can be uniformly distributed.

In other words, when the wind generated from one impeller 240 is discharged through the connected blower pipe 210, the air pipe 211, and the outlet 230, the discharged wind is different from the blower pipe 210, the air pipe ( 211) and the wind discharged through the outlet 230 so as not to collide with the wind to generate friction, so as not to affect the strength of the wind at all.

In addition, the wind discharged through the partition plate 320 is uniformly distributed to each flow path 310, so that the strength of the wind can also be maintained uniformly in either direction of 180° or 360°.

The horizontal guide part 330 is formed to extend outwardly from the upper part of the partition plate 320, and as the flow path 310 is formed in four, it is preferable that the horizontal guide part 330 is also formed in four correspondingly. And, the shape is formed to be curved, that is, it is formed to be curved so that the wind flowing through the flow path 310 can be discharged in the horizontal direction.

In other words, as shown in FIG. 5 , the direction of the wind moving in the vertical direction is naturally transformed by the horizontal induction unit 330 and finally becomes a horizontal direction so that it can be discharged to the outside, so that it can be discharged to the outside by 180° in the horizontal direction. Alternatively, the wind can be uniformly discharged in all directions over a 360° direction.

Here, as shown in FIG. 5 , protrusions 340 are formed on both sides of the discharge member 300 to extend outwardly so that the wind discharged to the outside does not spread and maintains straightness.

With the configuration of the protrusion 340, the wind discharged to the outside does not spread immediately as it is discharged, but rather maintains a straightness, so that the discharged wind can be maintained a little more.

In addition, the lower portion of the discharging member 300 is formed with a protruding frame 350 protruding from the lower portion and can be fixed to the upper outer side of the main body 200 through fitting or rotational coupling, and for rotational coupling, the It is preferable that a screw thread is formed on the upper outer side of the main body 200 and a screw thread is formed on the inner side of the protrusion frame 350, and in the case of the fitting structure, a general structure such as a sliding method can be applied.
