Benefits of technology

This patent describes an attachment for a hair styling apparatus that reduces turbulent airflow and the resulting noise of the device. The attachment has a duct with a gradually reduced cross-sectional area, creating consistent pressure and minimizing surface touch temperature. A cool wall also helps to minimize the attachment's temperature. A split vane design is used to ensure efficient attachment of airflow and minimized turbulence. Overall, this attachment improves the performance and comfort of hair styling devices.

Problems solved by technology

Heated airflow through an attachment may cause an outer surface of the attachment to become uncomfortably hot to touch.

Embodiment Construction

[0031]FIGS. 1, 3, 4 and 5 are external views of an attachment 10. The attachment 10 comprises an air inlet 12 for receiving an airflow from an air outlet end of a hot air styling device or similar apparatus. The air inlet 12 is generally circular in shape, to enable an air-tight connection with a generally annular air outlet end of the hot air styling device.

[0032]The air inlet 12 is in fluid communication with a duct 16. The duct 16 has an air outlet 18, which in this example is elongate in shape. An external surface of the attachment 10 is in the form of a cool wall 14 extending partially about the duct 16. The air outlet 18 extends beyond a top opening 20 of the cool wall 14.

[0033]FIG. 2 illustrates the three components of the attachment, and the internal features thereof.

[0034]A first component 21 defines a first half of the duct 16 and has a plurality of vanes 22, 23, 24, 25, 26 integrally moulded. A second component 28 defines a second half of the duct 16 and has the air inlet...

Abstract

An attachment including a duct having an air inlet for receiving an airflow from a hair styling apparatus, at least one vane located within the duct for directing the airflow towards an air outlet and the air outlet is elongate in shape and orientated generally parallel to the direction of airflow at the air inlet.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of United Kingdom Application No. 1605034.6, filed Mar. 24, 2016, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to an attachment for a handheld appliance, in particular a hair care appliance such as a hot air styling device or hair dryer.BACKGROUND OF THE INVENTION[0003]In a conventional hot air styling device, air is drawn into an inlet by a fan unit and directed towards the hair by an attachment or head. Depending on the style desired, the airflow may or may not be heated. Removable attachments are attached to the airflow outlet end of the hot air styling device or hairdryer, and serve to modify the velocity and form of the airflow emitted from the hot air styling device before it is incident upon the hair of the user.[0004]A concentrator is a known attachment which focuses and flattens the emitted airflow. Another known attachme...
