Title:
HAND-HELD HAIR DRYER
Document Type and Number:
WIPO Patent Application WO/2021/047626
Kind Code:
A1
Abstract:
The present application relates to a hand-held hair dryer, and belongs to the technical field of hair dryers. The hand-held hair dryer comprises a dryer head and a handle, the handle comprising a first end part connected to the dryer head, and a second end part away from the dryer head. An air channel is formed inside the handle, and an air sucking assembly used to suck external air into the air channel is arranged inside the air channel. The handle further comprises: a silencing assembly, the silencing assembly comprising a silencing support piece. The silencing support piece comprises a first grating used to eliminate high-frequency sound. The problem of too-loud sound in hair dryers can thus be solved. Because the hair dryer is provided with a silencing assembly, the silencing assembly is able to eliminate high-frequency sound by means of the first grating. The cross-sectional area of the airflow channel is increased, reducing air speed, and thus reducing noise when the hair dryer is operating.
