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.

Diffuser device for cosmetic liquids for hair dryers, characterized in that it comprises a cylindrical barrel, which can be associated with the blowing part of a hair dryer; said cylindrical barrel housing a diaphragm comprising a transverse septum which has a central expansion and lateral lobes; said lateral lobes defining respective lateral passages; said lateral passages and said transverse septum causing the air produced by said blowing part to pass in the form of two flows channeled to the exit of said device with laminar motion. The device makes passage of the air that passes through it more uniform in pressure and temperature, and at the same time enables cosmetic products to be dispensed for hair treatment.

A concentrator and hair dryer including a concentrator are provided. The concentrator may include a head having at least one flow path provided therein to enable gas discharged from a gas discharge of the hair dryer to flow therethrough, and a body that extends backward from the head and coupled to a main body of the hair dryer. Accordingly, the concentrator may be securely coupled to the hair dryer to prevent separation and shaking upon use.

One aspect of the present invention provides a haircare device (10) configured for being used when styling hair. The hair care device comprising a hollow body (101), an air inlet (102) through which air can enter the hollow body, and a hair receiving portion (103) on the outside of the hollow body, wherein the hair receiving portion comprises multiple air outlets (104) through which In air can exit the haircare device. The haircare device further comprises a fan (105) configured for transporting air from the air inlet to the air outlets. The hair receiving portion comprises multiple slats (106) provided between respective pairs of air outlets under an obtuse angle with the hair receiving portion, wherein the slats and the air outlets are positioned along a straight line (109), and wherein the multiple slats have a substantially rounded surface (111) on the outside of the hollow body such that in use an airflow is generated that moves predominantly along the hair receiving portion along the straight line.

Systems are provided for a hair dryer. A hair drying system can include a plurality of different types of accessories and a hair dryer having an output end configured to supply air. The output end can include an attachment assembly having a retaining mechanism configured to engage each of the plurality of different types of accessories to retain a selected one of the different types of accessories on the hair dryer, an alignment mechanism configured to align one of the accessories in a predetermined rotational orientation relative to the output end, and an accessory detection assembly configured to move to one of a plurality of predetermined structural configurations based on the type of accessory attached to the hair dryer. The hair dryer can further include a controller configured to control the supply of air through the output end in dependence on the predetermined structural configuration of the accessory detection assembly.

Hairstyling devices include one or more heat transmissive elements having a coating disposed thereon, the coating having ceramic and lava rock incorporated therein. The use of lava rock-containing coatings as described herein results in hairstyling devices with heat transmissive elements exhibiting enhanced heat retention, faster heat recovery, and increased ion emission. Furthermore, lava rock-containing coatings have been found more durable than equivalent heat transmissive element coatings that do not have lava rock incorporated therein.

A hair dryer has a primary air flow path and a secondary air flow path. The primary air flow path is operable to dry hair using suction in a first mode of operation. The secondary air flow path is operable to blow dry hair in a second mode of operation. In the primary mode of operation, the motor and fan assembly of the secondary air flow path is operated in reverse to direct air towards hair that is being dried by suction.

A hairdryer includes a casing having a main body having a main through cavity containing an electric motor and a fan to generate an air flow with a settled speed; an inner diffuser inside the main through cavity at the front outlet opening of main body and includes a through cavity having a passage section decreasing towards the front outlet opening to increase the speed of the air flow; the main body includes at least one side opening at the front outlet opening to enable air from outside entering into the main through cavity to increase an air output flow rate from the front outlet opening; an outer outlet element is reversibly coupled to the front outlet opening and includes an outflow tubular portion and a coupling tubular portion inserted into the front outlet opening to close the side opening and prevent the air from entering the main through cavity.

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 digitally controlled hairdryer has removable attachments that are used to style hair. The hairdryer is powered with AC and DC power, with the DC power supply being separate from the main body. The removable attachments are powered and controlled by the hairdryer. The oscillating attachment has a motor that moves an oscillating portion to direct airflow from the outlet of the hairdryer.
