Embodiment Construction

[0030] figure 1 , 3 , 4 and 5 are external views of the accessory 10. The accessory 10 includes an air inlet 12 for receiving an air flow from an air outlet end of a hot air profiling appliance or similar appliance. The air inlet is generally circular in shape to enable an airtight seal connection with the generally annular air outlet end of the hot air profiling device.

[0031] The air inlet 12 is in fluid communication with a conduit 16 . The duct 16 has an air outlet 18 which is elongated in this embodiment. The outer surface of the attachment 10 is in the form of a cold wall 14 extending partly around the duct. The air outlet 18 extends beyond the top opening 20 of the cold wall 14 .

[0032] figure 2 The three parts of the attachment and their internal structure are shown.

[0033] The first portion 21 defines the first half of the duct 16 and has a plurality of fins 22 , 23 , 24 , 25 , 26 integrally molded. The second portion 28 defines the second half of the d...

Abstract

An attachment including an air inlet for receiving airflow from a hair styling apparatus, an air outlet, a duct for conveying air from the air inlet to the air outlet, wherein the air inlet is located at one end of the duct, and the air outlet extends along the length of the duct and the cross-sectional area of the duct decreases in size from the air inlet along the length of the air outlet.

Description

technical field [0001] The invention relates to an accessory for a hand-held appliance, in particular a hair care appliance, such as a hot-air styling device or a hair dryer. Background technique [0002] In traditional hot air styling appliances, air is drawn into the inlet by a fan unit and directed towards the hair through the attachment or head. Depending on the desired shape, the air flow may or may not be heated. The removable attachment is attached to the air outlet port end of the hot air styling device or hair dryer and is used to change the speed and form of the air flow emitted from the hot air styling device before the air flow hits the user's hair. [0003] Convergents are known accessories that converge and flatten the emitted air stream. Another known accessory is a diffuser, which reduces the velocity of the emitted air stream. The flow of heated air through the accessory can cause the outer surface of the accessory to be uncomfortably hot to the touch. I...
