Include. By arranging the first rotating blade 310 and the second rotating blade 320 up and down while including two or more rotating blades, the width of the portable fan 1 can be narrowed, thereby increasing portability. That is, by making the portable fan 1 in a vertically long shape, it can be easily stored in a user's pocket or bag, and by arranging two or more rotating blades, the movement of air is smoother and the user can It can effectively increase the amount of wind felt.

The rotating blade is accommodated in the fan body including ventilation holes (410, 420) formed at the front and rear of the rotating blade so that wind passes through the rotating blade, and is located at the lower end of the rotating blade inside the fan body to operate the rotating blade.

You can have a width of. In addition, the control circuit board 800 has a surface direction facing upward and downward (ie, a direction perpendicular to the direction from the first rotating blade 310 to the second rotating blade 320). Can be prevented from being too long in the vertical direction.

The front of the fan body 100 and the rear of the fan body 200 may be combined to block not only the front and rear surfaces of the portable fan 1 but also the side portions of the portable fan 1 from the outside, and may have a curved shape at the side portion for this purpose.

FIG. 9 is an exploded perspective view of a portable fan according to another embodiment of the present invention, and FIG. 10 is an enlarged view of part A of FIG. 9, and FIG. 11 shows the first wiring and support of FIG. A more enlarged perspective view is shown.

9 to 11, a portable fan according to another embodiment of the present invention is formed on the body, fixed at both sides of the first wiring 810, and includes a plurality of supports 280 including a silicon material. Further comprising, the first between a first position fixed by the support body 280 of the first wiring 810 and a second position fixed by the support body 280 at a position adjacent to the first position It may be characterized in that the wiring 810 is bent so that it is not straightened. The support 280 is formed of a material containing silicon, so that the first wiring 810 is prevented from unnecessarily moving in the vertical, left and right directions, while also preventing the first wiring 810 from moving in the front and rear directions.

The first wiring 810 has a longer path than the second wiring 820 connected from the second rotating blade 320 adjacent to the control circuit board 800, and is controlled by passing through the side of the second rotating blade 320. Since it is connected to the circuit board 800, it is relatively easy to cause a short circuit. In addition, in the case of a portable fan, since a user carries it, a number of factors may cause an external shock, and there is a high possibility that a short circuit of the first wiring 810 may occur when an external shock occurs.

Accordingly, in the present invention, the first wiring 810 is formed to be bent, and a certain margin is secured by semi-fixing the first wiring 810 using the support 280 at some points of the first wiring 810, even if an external shock is applied, the control circuit board ( It is possible to prevent a short circuit between 800) and the first wiring 810 from occurring.

More specifically, the support 280 is formed of a material containing silicon, is formed on the fan body (a part of the inside of the fan body front 100 or the fan body rear 200), and a pair of supports 280 A portion of the support body 280 protrudes toward a portion facing each other while) facing each other, thereby fixing a portion of the first wiring 810. However, since the support bodies 280 are partially fixed by the first wiring 810 on both sides, since they are formed of a material containing silicon, the first wiring 810 can move when a specific force is applied. (In other words, the meaning of fixing by a support can be interpreted as meaning that it is supported without moving until a specific force is applied.)

As described above, if a part of the first wiring 810 fixed by the two supports 280 is the first position, the two supports 280 fix the first wiring 810 at the second position in the same position adjacent thereto. Likewise, the third position, the fourth position, the fifth position, where the first wiring 810 is fixed by the two support bodies 280 ... by the support bodies 280 such as the nth position There may be several positions of the first wiring 810 to be fixed. On the other hand, even when the first wiring 810 between the adjacent first position and the second position is not straightened but bent (that is, curved), so that movement occurs in the first wiring 810 due to an external shock. The first wiring moves only between the first position and the second position where the first wiring 810 is fixed while being adjacent, and the first wiring 810 secures a certain margin between the first position and the second position. Therefore, a short circuit between the first wiring 810 and the control circuit board 800 can be prevented as much as possible. In addition, since the first wiring 810 is fixed by the support 280 until an impact of more than a certain force is applied, the first wiring 810 is twisted or moved to an unnecessary position inside the fan body to operate the portable fan. It can prevent unnecessary influence on

Preferably, the support 280 is disposed so that the first wiring 810 is bent while changing right and left turns to fix the first wiring 810. By arranging the first wiring 810 to alternately bend to the right and left several times, even when the first wiring 810 is moved in a specific direction due to an external shock, the control circuit board 810 is made by a predetermined margin already secured. Since a short circuit between the and the first wiring 810 can be very effectively prevented, durability can be improved.

Meanwhile, although not shown separately, the support 280 applied to the first wiring 810 may be applied to the second wiring 820 as well, without limitation.

Considering the usage pattern of the user's portable fan, it is common to have the rotating blades in the direction of the user's face, and a motor (not shown) exists at the rear of the rotating blade to provide rotational power to the rotating blades. The electromagnetic waves generated by the motor (not shown) can be directed to the user's face by arranging the electromagnetic wave shielding unit 350 including the electromagnetic wave shielding agent in the centers 311 and 321 of the rotating blades. It can effectively block the heading. In addition, by covering only the vertical section of the center portion 311 and 321 of the rotor blades and not disposed on the blades 312 and 322, the weight of the rotor blades is prevented from unnecessarily increasing. While preventing the electromagnetic wave shielding force can be effectively generated. That is, by arranging the electromagnetic wave shielding unit 350 very effectively only where necessary and appropriate, unnecessary weight increase of the rotating blade can be prevented and the electric wave shielding power can be maximized.

The heat dissipation plate 751 includes a central plate overlapping the battery part 720 on a vertical line, thereby receiving heat directly transferred from the battery part 720, and transferring it to a radiating leg extending radially, thereby reducing the heat dissipation area. It can be increased to efficiently dissipate heat to the outside.

The heat dissipation legs may have a shape extending in the left and right directions of the center plate similar to the shape of the battery part 720, and the heat dissipation legs are disposed to be spaced apart from each other to minimize the weight increase due to the heat dissipation plate 751 and efficiently discharge heat. You can do it.

On the other hand, it may be characterized in that it is formed on the rear surface 200 of the fan body, and may further include a heat dissipating portion 255 formed to be opened so as to overlap with the radiating legs of the heat sink 751. In addition, the heat dissipating part 255 may be included in the area of the radiating leg of the radiating plate 751 and may be smaller than the area of the radiating leg. Accordingly, a part of the heat dissipation leg of the heat dissipation plate 751 is exposed to the outside and heat is efficiently discharged to the outside, while preventing the heat dissipation leg from being bent due to an external shock from coming out.
