A hair dryer may comprise a concentrator coupled to a main body part. The concentrator can include a nozzle passage, which is formed between the inner peripheral surface of a nozzle part and the outer peripheral surface of a passage-forming auxiliary part to guide, to the outside, gas provided from a gas discharge part of the main body part. A nozzle coupling part and an auxiliary coupling part are provided on the nozzle passage to space a passage-forming part including the nozzle part from the passage-forming auxiliary part, and can fix the passage-forming part and the passage-forming auxiliary part. Therefore, the concentrator can be easily coupled to the hair dryer. In addition, the gas can be stably supplied to a user through the concentrator. That is, user convenience can be increased.

Disclosed is an airflow hood for a hair dryer, which includes a fixing component, a flaring airflow shell, and a plate with holes for air exiting, the fixing component includes a sleeve and two clamping mechanisms arranged inside the sleeve at opposite sides, each of the clamping mechanisms includes two clips symmetrically arranged left and right and a pressing block located between the two clips for simultaneously pressing the two clips, wherein the clip includes a clip body extending in the circumferential direction of the sleeve, a mounting shaft which is used to hingedly install the clip body on the sleeve, a torsion spring, and a contact plate hingedly connected to the clip body via a rotating shaft.

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.

An attachment is described for a haircare appliance. The attachment comprises an inlet for receiving an airflow, and a body comprising one or more pairs of outlets, each pair of outlets comprising a first outlet and a second outlet. The attachment further comprises a valve moveable relative to the body between a first position in which the valve occludes the first outlet and the airflow is discharged from the second outlet of each pair of outlets, and a second position in which the valve occludes the second outlet and the airflow is discharged from the first outlet of each pair of outlets. The valve comprises a sealing element that contacts the body at a position between the first and second outlets of each pair of outlets.

The present disclosure relates to the technical field of electric hair driers, in particular to a double-duct hot air guide structure and a hair drier thereof. The double-duct hot air guide structure includes a shell, a heating module and a blowing module. The shell is provided with an outer sleeve-shaped body and an inner sleeve-shaped body mounted inside the outer sleeve-shaped body. A front end of the outer sleeve-shaped body is matched with a front end of the inner sleeve-shaped body through butting so that an inner air outlet inside the inner sleeve-shaped body correspondingly and an outer air outlet between the outer sleeve-shaped body and the inner sleeve-shaped body correspondingly are formed in a front end of the shell. The heating module is arranged between the outer sleeve-shaped body and the inner sleeve-shaped body.

A haircare appliance is provided for detecting a hair moisture content. The haircare appliance includes a processing element, at least one light emitting element emitting at least two wavelengths, and a sensor element, wherein the light emitting element is adapted to irradiate a portion of hair to be treated. The sensor element is adapted to receive a sensor reading from an acquisition region of the irradiated hair and generate a sensor signal dependent on the sensor reading and includes a spectral sensor element. The processing element is adapted to determine a moisture content of at least the irradiated portion of the hair from the sensor signal.

A hair care appliance is provided. The hair care appliance includes a handle and a body coupled to the handle via a rotational hinge joint. The body can be movable via the rotational hinge joint between a straight configuration in which the body is aligned with a longitudinal axis of the handle and a bent configuration in which the body extends along an axis transverse to the longitudinal axis of the handle. A fluid flow path extends between an inlet in the handle and an outlet in the body. The hair care appliance can be operated with minimal loss of fluid flow in either the straight configuration and the bent configuration. The hair care appliance includes a fan assembly in the handle and a heater assembly in the body that are positioned to create a balanced center of mass of the hair care appliance when operated by a user.

An attachment for a haircare appliance, the attachment having an air inlet, an air outlet, a curved surface adjacent to and downstream of the air outlet, and a switching member for directing airflow exiting the air outlet. The switching member is switchable relative to the air outlet between a first switch position, in which airflow exiting the air outlet passes between a first side of the switching member and the curved surface and attaches to the curved surface, and a second switch position, in which airflow exiting the air outlet passes over a second, opposing side of the switching member and is directed away from the curved surface.

A hair care appliance is provided and includes a heater having a heating element, an airflow passage extending from an airflow inlet to an airflow outlet, and an air mover for moving airflow along the passage from the inlet to the outlet. The appliance further includes a thermal barrier at least partly surrounding the airflow passage so as to restrict heat transfer from the heater to an external surface of the appliance. The thermal barrier includes an inner wall proximal to the heater, an outer wall distal from the heater, and a sealed evacuated space defined between the inner and outer walls.

A haircare appliance has a main body housing an airflow generator for generating an airflow, an intermediate attachment for detachably connecting to the main body, and a hair treatment attachment for detachably connecting to the intermediate attachment. The intermediate attachment has an inlet for receiving the airflow from the main body and an outlet for emitting the airflow. The hair treatment attachment is configured to receive the airflow from the outlet of the intermediate attachment and emit the airflow towards hair to be treated in use. The intermediate attachment has a sensor module for sensing a property of at least one of hair to be treated and the hair treatment attachment.
