According to this configuration, when the hair dryer 1 is used, when the air is discharged through the nozzle 100, the driving fan 130 is rotated by the discharged air, and by the rotational force of the driving fan 130 The driving disc 140 is decelerated and rotated so that the decelerated rotational force is again switched to the linear reciprocating motion of the connecting rod 160 via the crank 150 to turn the wind direction changing flap 170 to the left and right The wind ejected from the nozzle 100 can be diverted to a wide angle from left to right without being directed only in one direction.

The rear portion 110 of the nozzle 100 is formed in a circular shape in consideration of the fact that the discharge port 2 of the hair dryer 1 is generally circular, A notch is formed on the inner side of the discharge port 2 of the dryer 1 so as to be removable by an elastic coupling method. However, the present invention is not limited thereto, Therefore, detailed description and illustration are omitted.

The front face portion 120 of the nozzle 100 is formed to have a smaller sectional area than the rear face portion 110 to increase the speed of wind by concentrating the wind discharged from the hair dryer 1 into a narrow region. In the present embodiment, the shape of the front portion 120 is a rectangle having a larger width than that of the left and right widths.

A protrusion 102 protruding leftward and rightward outward is formed at an intermediate portion of the nozzle 100 in order to install the driving fan 130 and the driving disc 140. The protrusion 102 In order to minimize the resistance caused by the driving fan 130 and the driving disk 140 when the air flows (discharged) in the nozzle 100, the driving fan 130 and the driving disk 140 In order to allow the driving fan 130 to rotate only in one direction during the air flow inside the nozzle 100, the half of the driving fan 130 is not directly exposed to the discharged wind, So that rotation can be performed by being exposed to the wind.

The upper and lower ends of the shaft 132 of the driving fan 130 are rotatably coupled to the projections 102 and the lower ends of the nozzle 100, A drive gear 142 is formed at an outer periphery of the drive disk 140 so as to be gear-engaged with the drive gear 134 of the drive fan 130. The drive disk 140 includes a drive gear 142, The driving force of the driving gear 142 formed on the outer periphery of the driving disk 140 may be increased by more than the driving force of the driving gear 134 by 10: 1, so that the driving disk 140 rotates once when the driving fan 130 rotates 10 times.

One end of the crank 150 is coupled to an eccentric position on the driving disk 140 and the other end of the crank 150 is slidably inserted into a slot 162 formed on one end of the connecting rod 160 The crank shaft 150 is pivoted by the rotational force of the driving disc 140 and the oscillating motion of the crank 140 is switched to the reciprocating motion of the connecting rod 160 in the left and right direction.

The directional switching flap 170 rotates the intermediate flap 172 and the left and right side flaps 174 and 176. The left and right side flaps 174 and 176, And the intermediate flaps 172 and the side flaps 174 and 176 are provided with pivot shafts 173, 175 and 177 at intermediate portions thereof. The pivot shafts 173, 175 and 177 are rotatably fixed to the nozzle 100, The rear end of each of the flaps 172, 174 and 176 is connected to the connecting rod 160 by a pin so that the flaps 172, 174 and 176 are reciprocally rotated left and right about the rotating shafts 173, 175 and 177 in the linear reciprocating motion of the connecting rod 160 do.

The side flaps 174 and 176 can be actuated to extend more than a predetermined angle to the left and right outside of the front portion 120 of the nozzle 100 as shown in the operating state diagrams of Figs. This is because, when the intermediate flap 172 is installed only in the front part 120 having a narrow width, the angle of change of the wind direction is limited, and the left and right sides of the front part 120 are opened, The side flaps 174 and 176 are disposed and rotated so that the opening angle of the front portion 120 of the nozzle 100 can be extended.

The nozzle for a hair dryer according to the present embodiment having such a structure is mounted on a discharge port of a hair dryer, and the wind direction is automatically switched in the left and right direction as the flap is rotated by the wind blown out. Therefore, even if the user uses the wrist to shake the hair dryer, It is possible to prevent the user from waving the wrist easily. Also, the user can prevent the wrist from being easily tired, Only the nozzle of the present embodiment is mounted on the hair dryer, and the above-described functions are exerted, thereby reducing the burden of replacing and purchasing the entire hair dryer.

In the present invention, the driving fan or the driving disc may be configured such that rotational motion is suppressed by a stopper operated from the outside of the nozzle, so that the turning operation of the flap can be controlled by the operation of the stopper. And can be manufactured in such a manner that rotation is suppressed by being in contact with or separated from the driving fan or the driving disk while being depressed downward by one press and depressed downward by being depressed again, .
