The present invention relates to a wired / wireless combined use hair dryer device using a hybrid power adapter that can reduce the weight of a small household appliance by implementing a hybrid power adapter that can be detached freely.

In general, a hair dryer applies commercial power from a power supply to a device to heat air sucked from the outside, and then blows the heated air to the front of the device to remove water from the hair in a short time. Or to set the user's head to the desired shape.

More specifically, the hair dryer is used to supply the warm air or cold air to the hair through the air inlet air sucked through the air inlet to set or dry the hair. Heater wires are arranged, and the heater wires have a structure in which hot air is blown out through an air outlet while the heating is performed by a user's operation, and in the case where there is no heating of the heater wires, cold air is blown out through an air outlet. .

On the other hand, since such a hair dryer device requires high power to supply warm air, according to the prior art, most of the hair dryers were supplied with AC power by wire. There is a growing interest in small appliances using power supply.

However, in order to supply power in a wireless manner, a method of embedding a battery that outputs DC power is required.However, if a method of incorporating a battery that supplies only DC power is used in a hair dryer device, hot air is emitted. There is a problem that it is difficult to secure the high power required for this purpose, and since the product requires an AC / DC converter that converts AC power into DC power to charge the battery, the size of the product increases and consequently becomes heavy. It was difficult to carry to women who mainly use the problem.

Therefore, there is an urgent need for a technology related to a realistic and applicable hair dryer device that can be implemented while a wireless hair dryer device is portable.
