  • Patent number: 11844408
    Abstract: A diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Gas discharged from the main body is introduced into the diffusing case through a gas inlet hole defined at the rear side. The gas introduced into the diffusing case is discharged from a front side of the diffusing case. The diffusing case has a concave or curved structure such that an inner diameter of the diffusing case increases in a forward direction. A guide frame provided inside the diffusing case to guide a flow of the introduced gas includes a diffusion portion or protrusion provided to face the gas inlet hole to diffuse the gas introduced through the gas inlet hole.
