  • the power supply 200 supplies AC power to the hair dryer according to whether the intensity of the optical signal according to the event signal is equal to or greater than a preset threshold. It can be supplied to the unit 1000 .
  • the power supply device 200 is provided at one end of the power cable, and may supply at least one of AC power and DC power to the hair dryer unit through a connector physically connectable to the connection terminal of the hair dryer unit 1000 .
  • the power cable may include first and second output lines for supplying AC power, third and fourth output lines for DC power supply and ground use, and a fifth output line for receiving event signals. .
  • the first to fifth output lines may be accommodated in the power cable to a depth of at least 5 mm or more based on both ends of the power cable.
  • the connector may be implemented in the form of a 5-pin receptacle for receiving the 5-pin connector of the hair dryer 1000 to be connected to each of the first to fifth output lines.
