Abstract
The hair dryer includes a housing body that includes an air intake opening and an air outlet opening. The air outlet opening includes a non-ionized air outlet opening and an ionized air outlet opening. A fan is disposed within the housing body for introducing air into the housing body through the air intake opening and directing the air to the air outlet opening. An ionized air passage mechanism is formed within the housing body and is connected to the ionized air outlet opening. An air ionizing device is disposed within the ionized air passage mechanism for generating ionized air. Under this configuration, ionized air generated by the air ionizing device is discharged from the ionized air outlet opening and non-ionized air is discharged through the non-ionized air outlet opening such that both ionized air and non-ionized air are blown together from the air outlet openings of the hairdryer against hair.
