Traditional hairdryer generally has longer power line. While being used, the power line will be wrapped together, which is difficult to separate. While not being used, the power line will not be a good storage, which is very trouble. Helix hairdryer designs the longer power line into spiral elastic shape, which is on the bottom of hairdryer. While being not used, helix and hairdryer is integrated into whole. While being used, you only need to gently pull and it could be freely elongated. This method could ensure that the power line could not be wrapped, which could effectively storage, and is convenient and practical.
