A hair diffuser includes a connection member having a chamber wall that forms an air inlet that is connectable to a hair dryer and a cover member that is connected to the chamber wall of the connection member to form an interior chamber between the cover member and the connection member. The cover member has at least one generally vertically aligned inner circumferential wall having a longitudinally extending vent that directs air flow toward a central axis of the cover member.

A hairdryer including: a handle; a body comprising a duct extending within the body; a fluid flow path extending through the duct from a fluid inlet through which a fluid flow enters the hairdryer to a fluid outlet for emitting the fluid flow from a front end of the body; a primary fluid flow path extending at least partially through the body from a primary fluid inlet through which a primary fluid flow enters the hairdryer to an annular primary fluid outlet at a front end of the body; a fan unit for drawing the primary fluid flow through the primary fluid inlet; and an attachment for adjusting at least one parameter of fluid emitted from the hairdryer, the attachment being attachable to the hairdryer so that the attachment protrudes from the front end of the body, wherein the attachment is configured to inhibit the generation of the fluid flow.

A hand held hair dryer is provided herein with a split nozzle having a first nozzle arm and a second nozzle arm arranged opposing the first nozzle arm, such that a slot region is formed between the first nozzle arm and the second nozzle arm. The first nozzle arm and the second nozzle arm each include a plurality of air vents, which are configured to direct air flow within the slot region simultaneously from multiple opposing directions. In some embodiments, the hair dryer is further provided with a moveable component, which is selectively configurable to direct the air flow within the slot region simultaneously from multiple opposing directions, or to redirect the air flow in a primarily forward direction out a front end of the split nozzle.

An attachment for a haircare appliance, the attachment having a main body including an air inlet and an air outlet. The attachment has a guide for directing airflow from the air outlet across a curved surface of the main body, such that airflow directed by the guide generates a first force to attract hair toward the curved surface, and a second force to push hair away from the curved surface. The main body is rotatable relative to the guide between a first position in which airflow exiting the air outlet is directed by the guide and a second position, in which airflow exiting the air outlet is not directed by the guide.

A diffuser includes an air inlet for receiving an airflow from a hair dryer, a grille having a plurality of air outlets for emitting at least part of the airflow from the diffuser, a baffle having an outwardly tapering wall which defines a diffusing air chamber through which the airflow passes between the air inlet and the air outlets, and an external wall which surrounds the wall of the baffle to define a second air chamber therebetween. The second air chamber has a plurality of ports in fluid communication with the ambient atmosphere.

A diffuser includes an air inlet for receiving an airflow from a hair dryer, an external grille having a plurality of air outlets for emitting at least part of the airflow from the diffuser, and an internal grille located between the air inlet and the external grille.

An attachment assembly for an air-moving appliance includes a diffuser attachment and a hair engagement cover. The diffuser attachment includes an inlet end configured to removably attach to the air-moving appliance. The inlet end includes an inlet for airflow to enter the diffuser attachment and the outlet end includes a diffuser surface defining discharge openings for airflow in part to expel from the diffuser attachment. The diffuser surface is curved relative to an exterior of the diffuser attachment. The hair engagement cover includes prongs arranged to extend outward from the diffuser surface when the hair engagement cover is attached to the outlet end. The attachment assembly has a first configuration in which the hair engagement cover is not attached to the diffuser surface of the diffuser attachment, and a second configuration in which the hair engagement cover is attached to the outlet end of the diffuser attachment.

A hair styling device for use with an end styling attachment. The hair styling device comprises a housing, and the housing comprises a motor, a fan, a heating element, and an air concentrator. A styling attachment is configured to be removably attached to an end of the air concentrator and the styling attachment comprises a comb and an air diffuser. The comb of the styling attachment may comprise three paired rows of teeth having differing lengths and shapes, and the styling attachment may further comprise temperature and/or proximity sensors therein.

A hair blow-dryer includes a scent charge receptacle on the side of the air tube, preferably downstream from the heating element. Openings within the scent charge receptacle extend through the air tube to let ambient air flow through the receptacle and into the air stream within the air tube. A scent charge is placed within the scent charge receptacle, providing a fragrant scent that flows into the air stream, and is blown onto a user or hair style customer. Scent charges may take various forms, including absorbent materials that absorb fragrant oils, fragrant gel packs, or solid materials infused with fragrant compositions. Another embodiment includes an extension attachment for a commercially available hair blow-dryer, including the scent charge receptacle on an outer side thereof.

A carbon formed body covers an outlet of a dryer. The carbon formed body is formed into a disc made from isotropic high-density graphite, and elongated holes are provided along a spiral line so as to penetrate through the disc. Hence, the opening areas of the carbon formed body can be extended while preventing reduction in the strength of the carbon formed body. Therefore, when the dryer that includes the carbon formed body attached to the outlet is in use, a smaller pressure loss is caused at the carbon formed body and the heat accumulation phenomenon is prevented. Furthermore, breakage of carbon formed bodies is inhibited at the time of manufacturing.
