  • the present invention refers to a device designed to air diffusing to facilitate hair drying and shaping.
  • Air diffusing device have been known for some time allowing the user to hair drying and at the same time to hair shaping or curling by using a brush or other devices suitable for use.
  • such a known in the art device is provided with an air inlet, a resistance suitable for heating the air entering the diffuser and a perforated surface which acts as an air outlet suitable for allowing the hot air passage through these holes in order to dry the hair.
  • This known in the art device typically remains in operation for a particularly long period, since the hair curling action takes a long time.
  • the hair is at risk of being damaged by being subjected to a hot air flow for a long period of time.
  • the Chinese utility model published under no. CN 210 353 624 describes a hair dryer wherein a first air duct is arranged on the air outlet surface of the fan; a second air duct is arranged on the air outlet surface of the fan; a part of the air flow generated by the rotation of the fan exits through the first air duct, a part of the air flow generated by the rotation of the fan exits through the second air duct, in the first air duct is arranged a duct heating element and the heating element heats the cold air flowing in the first air duct into hot air.
  • JP 2010/274050 discloses a hair dryer configured to divide the air flow into a hot air flow passage for blowing hot air and a cold air flow passage for blowing cold air by setting a heating element in an intermediate position between the fan and an outlet.
  • the present application relates to an air emitting device for hair treatment, not indicated in the appended claims.
  • an air emitting device for hair treatment comprising an entry air area, a casing suitable for containing within it at least one heating element suitable for heating said air inside said casing, an outlet area for said air heated by said heating element, opposite to said entry air area, and an external body arranged around said casing.
  • the air emitting device also comprises an interspace placed between said casing and said external body so that the air present in said interspace is not capable of being heated by said at least one heating element.
  • the interspace also includes at least one outlet for said air not heated by said at least one heating element.
  • the hair subjected to treatment with said air emitting device receives an air flow at a lower temperature because it is not directly heated by said heating element, such as to allow the hair treatment, such as for example the curl formation, without damaging the hair itself, contrary to what happens in the known in the art devices not having such an outlet for the air not heated by said heating element.
  • Said at least one outlet area for said air not heated by said at least one heating element is different from said outlet area for said air heated by said at least one heating element.
  • Said outlet area for said air heated by said heating element consists of a grid consisting of a substantially concave base surface provided with a plurality of holes for the exit of said air heated by said at least one heating element.
