Abstract: A diffuser may include a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid (such as gas or air) discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. The fluid introduced into the diffusing case is discharged to an outside through a front side of the diffusing case. A light irradiator may be provided inside the diffusing case to irradiate light toward the front side of the diffusing case. The light irradiator may include a plurality of light emitters arranged on a circuit board to emit light. Some of the plurality of light emitters may be spaced apart from others of the plurality of light emitters in a front-rear direction.

Abstract: A diffuser for a hair dryer includes a diffusing case having a rear side removably coupled to a main body of the hair dryer. Air or fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. A n open surface is defined at a front side of the diffusing case such that the air introduced into the diffusing case is discharged to an outside through the open surface. The diffusing case includes a front circumferential portion surrounding the open surface. The front circumferential portion includes a first portion and a second portion. The first portion is at least partially located further forward of the second portion.

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.
