Description

{A Rotatable hair drier}

The present invention relates to a hair dryer. More particularly, the present invention relates to a hair dryer, and more particularly, to a hair dryer in which a dryer body having a discharge port is rotatable at its tip end so that the direction of spraying wind can be extended at wide angles Dryer.

Generally, a hair dryer is provided with a blowing fan that sucks air from a side or rear of a body by a motor installed inside the body and discharges the air through a discharge port at the front end. In the body, A heater is installed for heating.

In the case of drying the hair using such a conventional hair dryer, it is necessary to shake the wrist of the hand holding the hair dryer handle from side to side or up and down. However, people working in the hairdressing industry have to deal with a lot of guests all day long and have to dry hair or hair with the hair dryer, so that the wrist arthritis is caused by the twisting of the fingers and wrists, and the muscle stiffness And it became a factor to cause occupational diseases.

In order to solve the above problems, there has been proposed a hair dryer capable of adjusting the wind direction as in Patent Documents 1 to 4.

On the other hand, in the hair dryers disclosed in Patent Documents 1 to 4, a flap in a flat shape is rotated in the discharge port or in front of the discharge port to change or extend the wind direction. However, There is a drawback that the hair dryer user must still rotate the entire hair dryer by using the wrist because the effect of the directional change is insignificant or the angle of the blower extending to the left and right is not wide enough.

As shown in Patent Document 1 and Patent Document 2, a flap is provided inside the discharge port, and the flap is linked to the driving fan by a wind to be pivoted, It is difficult to assemble due to the degradation of performance and complexity of the internal structure, so that the price of the product is increased, and there is a possibility of failure due to breakage or dropout of internal parts during use.

In the case of a hair dryer in which a pair of flaps are rotatable in the left and right direction in front of a discharge port as in Patent Document 3, the flap is exposed to the outside, so that there is a high possibility of breakage during use, There is a problem that the air resistance is increased and the blowing ability of the hair dryer is lowered.

Also, in the case of Patent Document 4, the flap is attached to the front left and right sides of the nozzle, and there is a fear of damage due to external exposure, and when the safety cover is put on the front, there is a problem that the blowing angle of wind is limited.
