Abstract
The present disclosure provides a hair dryer including: a housing, having an air duct, an air inlet and an air outlet both communicated with the air duct; a fixing sleeve, arranged in the air duct of the housing, an inner wall surface of the fixing sleeve being provided with an elastic contact layer; and a fan, embedded in the fixing sleeve and abutted against the elastic contact layer. The present disclosure aims to reduce the fan vibration during the operation of the hair dryer, so as to reduce the noise generated by the hair dryer, thereby mitigating the impact of the noise on users.
