The ectoparasite eradicating device is configured to eradicate lice and eggs by conveying and directing heated air to the base of the hair shaft where lice live and lay egg by connecting to a common commercially available blow dryer. The device includes a rotatable sleeve to facilitate maintenance of contact of the lower concave edge with the scalp over a range of movements of the blow dryer. A plate with a flow disrupting lip separates the hot air flow from the scalp to avoid burning, while ensuring effective treatment of the hair to the root at the edge of the plate.

A handheld electric hair drier comprising a main body including a primary fluid inlet, a primary fluid outlet, a fan unit, a heating element, and a fluid flow path, and a handle. The fluid flow path comprises a primary fluid flow path that extends from the main body to the primary fluid outlet along a straight line, a side fluid flow path, and a wall-defined fluid flow path. Air fluid drawn through the side fluid flow path and the wall-defined path enters the fan unit through the primary fluid flow path. The fan unit is arranged on the primary fluid flow path, and the fan unit sucks fluid into the primary fluid flow path and transmits the fluid to pass through the heating element, so that the fluid in the primary fluid flow path is heated. The hair drier can provide high-pressure jet airflow and improve the air supplementing speed.

An attachment for a hair dryer that is movable between a first position and a second position in order to alter one or more characteristics of the airflow therethrough. In one embodiment, an attachment having multiple facets and types of projections with varying stiffness are provided on an outer housing that can be rotated relative to a base by the user. In a second embodiment, an attachment having a concave surface with prongs extending therethrough that can be moved such that the exposed portion of the prongs are lengthened or shortened, as desired.

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.

A hair dryer comprises a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port, a water collection member located inward of the inlet port wherein hair being dried is directed against a screen positioned forward of the water collection member, whereby ingress of hair into the interior of the primary air flow path is inhibited.

The present invention relates to a metal hair dryer with an adjustable air volume. The hair dryer comprises: an air-blocking plate is used for adjusting the air intake volume of the hair dryer; a field data extraction device comprising an infrared transmitter, an infrared receiver, an ARM11 processor and an extraction controller, wherein the infrared transmitter is located on a data collection device and is used for vertically transmitting an infrared signal downwards, and the infrared receiver is located beside the infrared transmitter and is used for receiving the infrared signal, which is reflected back; and an air-blocking plate driving device is used for enabling an operation on the air-blocking plate when the human body detection device determines that there is a human body. By means of the present invention, an effective authentication mechanism is introduced for the hair dryer.

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 smart nozzle system for a hair dryer includes a proximity detection circuit, a temperature sensing circuit, a speed detection circuit, and a rotating nozzle vane, among other features. The nozzle includes a microcontroller and a wireless communication module to interface with an external computing device via an application. Also included is a camera, a timer, a fluid dispenser, and a therapeutic UV light. The power supply can be a dynamo powered by air flowing through the nozzle. The nozzle can be an add-on to existing hair dryers or can be integral with a hair dryer system.
