A hair dryer attachment is formed of a hollow cylinder made of high-heat resistant material and includes a first end and a second end, opposite the first end. The hollow cylinder extends an axial distance between the first end and the second end. The first end embodies a first opening that is larger in diameter than a second opening embodied by the second end. Vertical ribs extend inwardly from an internal surface of the hollow cylinder that are equally spaced along the internal surface of the cylinder. A plurality of hole patterns consisting of between five and fifteen holes that are centered along the interior between each of the vertical ribs. The first opening at the first end of the attachment is configured to be securely fixed over a barrel or air source of a hair dryer. The first end preferably comprises silicone rubber to facilitate a friction fit.

The diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side and discharged from a front side of the diffusing case. A light irradiator is provided inside the diffusing case to irradiate light toward the front side of the diffusing case, and a light diffusion frame is provided in front of the light irradiator. The light irradiated from the light irradiator is diffused while forwardly penetrating the light diffusion frame.

A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case having a rear side coupled to the main body. The main body is provided such that a front end of an outer wall surrounds a gas or air outlet, and a first coupling portion coupled with the diffuser is provided at the front end. The diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas or air inlet hole defined at the rear side. The first coupling portion includes a power transmitter to supply power to the diffuser, and the second coupling portion includes a power receiver to receive the power from the power transmitter.

A diffuser for a hair dryer includes a diffusing case, a guide frame provided inside the diffusing case to guide a flow of gas introduced into the diffusing case, a light irradiator provided inside the diffusing case and in front of the guide frame to irradiate light toward a front side of the diffusing case, and a discharge cover provided at the front side of the diffusing case. The discharge cover includes a gas discharge hole to discharge the gas inside the diffusing case to outside. The discharge cover includes a plurality of massage protrusions to press a target located in front of the discharge cover.

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.

A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case. The main body is provided such that a front end of an outer wall surrounds the gas outlet, a first coupling portion coupled with the diffuser is provided at the front end, and the diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas inlet hole defined at a rear side. The first coupling portion includes a wireless power transmitter to wirelessly supply power to the diffuser, and the second coupling portion includes a wireless power receiver to wirelessly receive the power from the wireless power transmitter.

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.

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.

A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case and a discharge cover. The discharge cover includes a plurality of massage protrusions protruding forward to press a target located in front of the discharge cover and at least one moisture measurement protrusion provided to measure a moisture amount of the target.

A portable hand held hair dryer operable in a mode of operation to draw air through hair into the hair dryer. The hair dryer having at least one cyclone operable to separate water from the air flowing therethrough and an exterior separated water storage tank.
