Disclosed is a diffuser and a hair dryer. The diffuser includes a casing, which includes: an air inlet end, configured to be in communication with a main body of the hair dryer; and an air outlet end, defining at least two first air outlet holes, where air outlet directions of the at least two first air outlet holes are configured to be distributed at intervals clockwise or counterclockwise around a center of the air outlet end. The technical solution of the present disclosure improves the hair blowing effect of the hair dryer.

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 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. The diffuser attachment has a motor that is connected to a slider that moves along a central axis. The slider moves wire fingers between a grasped and relaxed position. The ends of the fingers are connected to a blocking membrane that directs airflow through an outlet aperture that is small in the grasped position and large in the relaxed position.

A multiple nozzle attachment for a hair dryer is provided. The multiple nozzle attachment has at least two nozzles that concentrate air flow and optimize exiting air pressure while maximizing air flow volume.

A hair dryer (10) has a hand-held housing comprising an air inlet (12), an air outlet (14), a motor (1) between said air inlet (12) and said air outlet (14) to draw air in from said air inlet (12) and drive air out from said air outlet (14). A heating element (17) is located in said air flow between said air inlet (12) and said air outlet (14). The hair dryer (10) further comprises a filter on said air inlet (12). The filter comprises a metal filter plate (20) bearing a plurality of holes, wherein at least some of said holes have a maximum lateral dimension of less than 1.5 mm and wherein vertical walls of said holes through a thickness of said filter plate are substantially straight or at least partially concave.

A handheld hair dryer includes a body extending about an axis and including a first end, a second end, an inner wall, and an outer wall. The outer wall and the inner wall extend from the first end of the body to the second end of the body and define a cavity therebetween. A central passage is defined by the inner wall. The hair dryer also includes an inlet defined by the inner wall and an outlet for the airflow to exit the cavity. The inlet is defined by the inner wall intermediate the first end and the second end. The hair dryer is configured to direct the airflow through the cavity and towards the outlet. The hair dryer further includes a handle connected to the body, a fan, and a motor positioned at least partly within the handle and coupled to the fan.

Hairdressing device (1) for shaping hair, comprising a holder (2) arranged with an air distribution chamber (3) and arranged with a plurality of teeth projecting from the holder (2), the plurality of teeth comprises combing teeth (20) and hollow teeth (50, 5) wherein each hollow tooth (50) comprises a channel (51) with at least one outlet opening (52, 52a, 52b) for the air to flow from the air distribution chamber (3) and exit through the at least one outlet opening (52, 52a, 52b). The hollow teeth (50) and the combing teeth (20) are positioned in an alternating pattern (10) where a hollow tooth is placed next to a combing tooth, and the hollow teeth (50) is configured for the air to flow out from outlet openings (52) at opposite sides (AB) of a central longitudinal plane through the holder (2).

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.

Disclosed herein is a hairdryer attachment. The hairdryer attachment comprises an inlet section for receiving a flow of air in a first direction and an outlet section. A plurality of air channels are located within the outlet section for turning and separating the flow of air into a plurality of streams of air. The air channels are arranged such that the streams of air exit the outlet section in a plurality of different directions.

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.
