And the discharge port 111 can be opened by the second concave portion 123-2. At least a part of the second concave portion 123-2 may overlap the first main body 122-1 so that the discharge port 111 is closed. The opening area of the discharge port 111 can be changed by the overlap area of the second concave portion 123-2 and the first main body 122-1. The second concave portion 123-2 may be an isosceles triangular shape in which two hypotenuses extend to the left.

The open portion 124 can be determined by the first concave portion 122-2 and the second concave portion 123-2. The open portion 124 has a first concave portion 122-2 that does not overlap the second body 123-1 and a second concave portion 123-2 that does not overlap the first body 122-1 Can be determined by an outline.

The overlapped area between the first concave portion 122-2 and the first main body 122-1 and the overlapped area between the second concave portion 123-2 and the second main body 123-1 are equal to each other, And the movement of the second blade 123 can be changed. The open area is changed by the overlapped area between the first concave portion 122-2 and the first main body 122-1 and the overlapped area between the second concave portion 123-2 and the second main body 123-1 . The "wind speed" can be adjusted as the open area is adjusted.

The driving unit 150 may be disposed inside the exterior member 110. The driving unit 150 can move the first blade 122 and the second blade 123. That is, the driving unit 150 can provide the sliding movement power of the first blade 122 and the second blade 123. The driving unit 150 may include a first screw 151 and a first rotation motor 152.

[ 3 may be formed by screwing a second thread 151-2.

Since the first and second blades 122 and 123 are slidably coupled to the rails 121 and are constrained to rotate, the first screw 151 rotates to rotate the first connection 122 - The first blade 122 and the second blade 123 are moved in the left or right direction when the screw connection of the first connection hole 151-1 and the screw connection of the second connection hole 123-3 and the second screw thread 151-2 is tightened or loosened, You can move to the right.

The threading directions of the first thread 151-1 and the second thread 151-2 may be opposite to each other. That is, the helical inclination of the first thread 151-1 and the second thread 151-2 may be opposite to each other. As a result, the moving directions of the first blade 122 and the second blade 123 may be opposite to each other.

Hereinafter, the operation and operation of the first embodiment will be described with reference to Figs. 4A, 4B, and 4C. 4A is a conceptual view of the mobile unit 120 viewed from the front in the "pneumatic operation mode ". FIG. 4B is a conceptual view of the mobile unit 120 viewed from above in the" 4C is a conceptual view of the mobile unit 120 viewed from the front in the "gentle wind operation mode ". FIG. 4C is a conceptual view of the mobile unit 120 in the"

As shown in Fig. 4A, the first rotary motor 152 is in the stopped state, and the first blade 122 and the second blade 123 do not move. Therefore, the open area is maintained and the constant wind speed (paralysis) can be maintained.

As shown in FIG. 4B, when changing from the "stern mode" to the "strong wind mode", the first rotation motor 152 can rotate forward. The first blade 122 moves to the right side and the second blade 123 can move to the left side (the first blade and the second blade come close to each other) due to the forward rotation of the first rotation motor 152.

When the first blade 122 and the second blade 123 are brought close to each other, the overlap area between the first recess 122-2 and the second main body 123-1 and the overlapping area between the second recess 123-2 The overlap area of the first main body 122-1 increases, and the open area can be reduced.

The air blowing amount Q is maintained in the following formula, so that if the open area A is decreased, the air blowing speed V becomes faster. Therefore, it is possible to switch from the "stern operation mode" to the "strong wind operation mode" by the first rotation of the first rotary motor 152.

[Equation]

Air volume (Q, volume of discharged fluid per unit time) = open area (A, area of discharged fluid per unit time) × air velocity (V, moving distance of discharged fluid per unit time)

As shown in FIG. 4C, when changing from the "stern mode" to the "weak wind operation mode", the first rotation motor 152 can rotate in the reverse direction. By the reverse rotation of the first rotary motor 152, the first blade 122 moves to the left side and the second blade 123 can move to the right side (the first blade and the second blade are distant from each other).

When the first blade 122 and the second blade 123 are separated from each other, the overlap area between the first recess 122-2 and the second main body 123-1 and the overlapping area between the second recess 123-2 The overlap area of the first main body 122-1 decreases, and the open area can be increased.

Since the blowing amount Q is maintained in the following formula, if the open area A increases, the blowing speed V becomes slower. Therefore, by the reverse rotation of the first rotation motor 152, it is possible to switch from the "stern operation mode" to the "light wind operation mode".

[Equation]

Air volume (Q, volume of discharged fluid per unit time) = open area (A, area of discharged fluid per unit time) × air velocity (V, moving distance of discharged fluid per unit time)

The first blade 122 moves to the right due to the forward rotation of the second rotation motor 162 and the second blade 123 can move to the right due to the forward rotation of the third rotation motor 163. [

The screw connection between the first blade 122 and the second screw 161 and the screw connection between the second blade 123 and the third screw 164 are the same, (RPM) of the first blade 122 and the second blade 123 are the same, the moving speeds of the first blade 122 and the second blade 123 are the same. Thus, the open portion 124 maintains the open area and can move to the right. As a result, the "wind speed" can be maintained and the "wind direction" can be changed to the right side.

5E, the second rotating motor 162 and the third rotating motor 163 are rotated in the opposite direction to each other when the open portion 124 is to be moved to the left while maintaining the "wind speed" in the " All can be reversed. The first blade 122 moves to the left side by the reverse rotation of the second rotation motor 162 and the second blade 123 can move to the left side by the reverse rotation of the third rotation motor 163. [ In this case, the open portion 124 maintains the open area and can move to the left. As a result, the "wind speed" can be maintained and the "wind direction" can be changed to the left side.

In the second embodiment, the first blade 122 and the second blade 123 are independently controlled by the second rotary motor 162 and the third rotary motor 163, You can change both "wind speed" and "wind direction".
