Definitions

  • This invention relates to hair styling apparatus and, more particularly, to air diffusers for hair styling applications. More specifically, but not exclusively, this invention relates to an air diffuser attachment for use with a hair blower.
  • Air diffusers for hair styling applications are well known and are typically available in the form of a hair styling attachment comprising a coupling portion for attaching to the outlet of an air blower and a down-stream end for delivery of diffused air towards the scalp of a user.
  • Examples of known air diffusers are described, for example, in US 5,060,398, US 5,488,783 and US 5,638,608.
  • air diffusers are adapted for spreading a jet of concentrated air stream from a source hair blower and/or for slowing down the velocity of an air stream before delivery to a user.
  • Conventional air diffusers typically comprise an upstream air inlet and a downstream outlet of a significantly larger aperture than that of the air inlet.
  • An air baffle typically in the form of a grid with apertures, is mounted at the downstream end to force an incoming air stream to diffuse.
  • Such conventional air diffusers are bulky due to the need of a large diffusing volume and the need to have a transversal baffle spreading across the downstream outlet. Therefore, it will be advantageous if there can be provided an improved air diffuser for hair styling applications.
  • an air diffuser comprising a main body and an air diffusing baffle for hair styling, wherein said main body comprises an upstream end with an air inlet and coupling means for attaching to a hair blower, and a downstream end with an air outlet for delivery of air to a user, and said air diffusing baffle comprises an air baffling surface; characterised in that said air baffling surface is movable relative to said main body for varying effective level of baffling to an air stream from said air inlet portion.
  • the air baffling characteristics can be varied or adjusted according to individual requirements or for achieving specific styling objectives.
  • an air diffuser comprising a main body and an air diffusing baffle for hair styling, wherein said main body comprises an upstream end with an air inlet and coupling means for attaching to a hair blower, and a downstream end with an air outlet for delivery of air to a user, and said air diffusing baffle comprises an air baffling surface; characterised in that said air baffling surface is movable along the direction of air flow from said air inlet to provide variable adjustability of an effective level of baffling to an air stream from said air inlet portion.
  • said air baffling surface is movable between said downstream end and said upstream end to vary the effective baffling resistance.
  • an air baffling surface which can be moved intermediate the upstream and downstream ends and set to stay at a selected intermediate position provides enhanced flexibility.
  • said air baffling surface is movable towards and away from said air inlet portion to vary the effective separation between said air baffling surface and said air inlet. Similar, as the velocity of an air stream gradually reduces as the stream of air moves away from the air inlet, an air baffling surface which is movable towards and away from the air inlet portion could be effectively adjusted to set a desired separation between the air baffle surface and the air inlet to alter the baffling characteristics.
  • the effective separation between said air inlet and said air baffling surface is adjustable by moving said air baffling surface away from or towards said air inlet.
  • said air diffusing baffle comprises an air baffling member, said air baffling member being extendible from and retractable towards said coupling means.
  • said air inlet defines an inlet aperture, said air outlet defining an outlet aperture, said air outlet aperture being larger than said air-inlet aperture.
  • said air baffling surface of said movable air diffusing baffle is telescopically movable towards and away from said air inlet.
  • a telescopic extension and retraction system is advantageous since it is simple and space efficient.
  • a plurality of apertures is distributed on said air baffling surface of said air diffusing baffle.
  • said air baffling surface is convex towards said air inlet.
  • a convex baffling surface is advantageous since it provides a smooth and gradually expanding diffusing surface.
  • the diffuser further comprises an intermediate air diffusing baffle, wherein said intermediate baffle is disposed intermediate said air inlet and said air diffusing baffle, and said intermediate air diffusing baffle is movable relative to said air diffusing baffle and said air inlet.
  • an additional intermediate air diffusing baffle provides an added degree of flexibility so that a user can adjust the baffling characteristics according to the specific needs and/or preferences.
  • said intermediate air diffusing baffle is supported by a plurality of stays extending axially from said main body, and said air diffusing baffle being supported by a plurality of stays extending axially from said intermediate air diffusing baffle; characterised in that said air diffusing baffle and said intermediate air diffusing baffle are individually movable relative to said main body along said stays.
  • said intermediate air diffusing baffle and said air diffusing baffle are individually movable relative to said air inlet along an axial direction.
  • the deployment of individually movable diffusing baffles provides an added degree of flexibility for a user to suit specific applications.
  • said intermediate air diffusing baffle and said air diffusing baffle are individually and telescopically movable relative to said air inlet along an axial direction.
  • said intermediate air diffusing baffle comprises a hollow housing, said hollow housing being convex towards said air inlet and being concave towards said air outlet.
  • said main body, said intermediate air diffusing baffle and said air diffusing baffle are stackable with respect to each other.
  • the diffuser can be fully collapsed into a more compact size for more efficient storage and transport.
  • said air diffusing baffle comprises a hollow housing, said hollow housing being convex towards said air inlet and being concave towards said air outlet. More advantageously, each one of said intermediate air diffusing baffle and said air diffusing baffle is telescopically movable relative to said air inlet along an axial direction.
  • said intermediate air diffusing baffle defines a central aperture, said central aperture overlapping with said aperture of said air inlet.
  • said air diffusing baffle comprises a hollow housing, said hollow housing being convex with a rounded end extending towards said air inlet.
  • Fig. 1 is a top plan view of a preferred embodiment of this invention
  • Fig. 2 is a side view of the air diffuser of Fig. 1 in the fully extended configuration
  • Fig. 2A is a side view of the air diffuser of Fig. 1 in the fully retracted configuration
  • Fig. 3 is a cross-sectional view of the air diffuser of Fig. 2,
  • Fig. 3A is a cross-sectional view of the air diffuser of Fig. 2A
  • Fig. 4 is a view from bottom of the air diffuser of Figs. 2 and 2A
  • Fig. 5 is an exploded view of the component parts of the air diffuser of Fig. 1.
  • the air diffuser 100 comprises a main body 120 and a movable diffuser assembly 140.
  • the main body defines an air inlet at its upstream end, an air outlet at its downstream end and comprises an air diffusing housing 124 which inter-connects the air inlet and the air outlet.
  • the main body also defines a coupling means 122 for coupling the air inlet to a hot air source, for example, a hair blower.
  • the air diffusing housing 124 comprises a peripheral wall 130 which defines a downstream air-outlet aperture 132 and an upstream air inlet aperture 134 of the air diffuser.
  • the peripheral wall 130 forms a hollow air diffusing housing 124 which defines an air diffusing space so that air coming in from the air inlet and moving towards the air outlet will pass through the air diffusing space and will be spread before leaving the diffuser 100.
  • the air diffusing housing 124 is bowl shaped wherein the area of aperture defined by the peripheral wall 130 gradually increases as the aperture moves away axially away from the upstream end, that is, from the air-inlet aperture 134. As shown in Figs.
  • the air-outlet aperture 132 defined by the peripheral wall 130 at its downstream end is larger than that of the air-inlet aperture 134.
  • the bowl-shaped hollow air diffusing housing 124 defines a hollow air diffusing compartment 131 which flares towards the outlet aperture, as more particularly depicted in Fig. 3. Although a bowl-shaped housing has been depicted here, other form of housings which defines a flaring compartment, for example, a frustoconical housing, a pyramidal housing, or like shaped housing could also be used.
  • a coupling means 122 for coupling the air diffuser to the downstream end, for example, a nozzle, of a hair blower (not shown) is formed at its upstream end, and more specifically, adjacent the air inlet.
  • An exemplary coupling means of a bayonet type which comprises a collar 126 and a fastening means 128 are depicted in Figs. 2, 2A, 3 and 4.
  • the collar 126 forms a peripheral wall which is adapted to surround the air-outlet aperture of a hair blower upon coupling for maximum air coupling efficiency. This peripheral wall in effect defines the air-inlet aperture 134 of the air diffuser 100.
  • the fastening means is for fastening the air diffuser 100 to a hair blower when the diffuser has been coupled or attached to the hair blower.
  • the fastening means depicted in this example comprises three resilient hooks 128 for clipping onto the nozzle of a hair blower. Each of the hooks is resiliently urged in the radial direction for clipping on to the nozzle of a hair blower.
  • Other appropriate fastening means include, a screw threaded collar (with internal or external threads).
  • the hollow housing defined by the peripheral wall 130 and the collar member 126 are co-axial, that is, sharing a common longitudinal axis.
  • the collar member is also co-axial with the nozzle of a hair blower with which the diffuser collar member 126 is adapted to engage with during use.
  • the term "axis" or “axial” refers to the axis of the collar member or the nozzle of a hair blower. The axial direction substantially defines the direction of air flow from a hair blower.
  • the movable diffuser assembly 140 comprises a first movable air diffusing baffle member 150 (the "first baffle member”) and a second movable air diffusing baffle member 160 (the “second baffle member”)-
  • the first baffle member 150 comprises a hollow bowl-shaped concave body 152 with an air diffusing surface 154 and a central aperture 156.
  • the air diffusing surface 154 is convexly curved and is disposed opposite to the air-outlet aperture 132 of the main body 120 so that air exiting from the air-outlet aperture 132 will be diffused when encountering the convexly curved air diffusing surface 154 on moving towards the hair of a user. Part of the air exiting from the air-outlet aperture 132 will pass through the central aperture 156 of the first baffle member, move way from the coupling means, and then move toward the second baffle member.
  • the second baffle member 160 comprises another bowl-shaped hollow member 162 which comprises an air diffusing surface 164 which is disposed, at least partially, within the compartment 151 defined by the hollow bowl-shaped member 152.
  • the air diffusing surface 164 is convexly curved towards the air inlet.
  • a plurality of air diffusing apertures 166 are distributed on the bowl- shaped member 162 so that air coming out from the central aperture 156 can be diffused via the through apertures 166 or the external curved surface 164.
  • the first and the second baffle members 150, 160 are movable towards and away from the air-inlet aperture 134 or the coupling means.
  • the first baffle member 150 is axially movable and is movable relative to the peripheral wall 132 of the main housing to vary its axial separation with the air-inlet aperture.
  • the first baffle member 150 is supported by a plurality of posts or stays axially extending from the main body 120. The stays are adapted so that the first baffle member 150 can slide along the stays and along an axial direction to move towards and away from the coupling means.
  • the second movable baffle member 160 is supported on the internal bowl surface of the first movable baffle member by a plurality of axially extending posts or stays so that the second baffle member can slide relative to the first baffle member 160 and also along an axial direction.
  • the second baffle member will be moved towards and away from the bowl-shaped member 152 of the first movable baffle member 150.
  • the bowl-shaped members 152 and 162 are shaped and dimensioned so that the bowl-shaped member 162 of the second baffle member is receivable within the compartment 151 formed by the first movable baffle member and the first baffle member is receivable within the bowl compartment formed by the peripheral wall 132 of the main body.
  • each of the movable baffle members comprises an air diffusing baffle surface for varying the air diffusing characteristics of the air diffuser 100.
  • an air diffuser which can be re-configured into a more compact size for travelling or transport is provided.
  • the movable diffusers can be telescopically extended to an appropriate baffling level for use.
  • Each of the first 150 and second 160 baffle members is individually movable so that a user can adjust each of the baffle members independently.
  • the movable diffuser assembly comprises first and second baffle members, it will be appreciated that an air diffuser may only comprise a single movable baffle member, for example, either the first baffle member or the second baffle member, without loss of generality. Where a diffuser only comprises the first baffle member only, the central aperture 156 would be replaced by a plurality of smaller apertures or non aperture at all.
  • more than two individually movable baffle members can be incorporated into a diffuser of this invention.
  • an air diffuser of this configuration also enables the variation of air diffusing characteristics by adjusting the relative separation between the diffusing surfaces 154, 164 of the respective baffle members and the upstream end of the air diffuser.
  • each of the main body and the baffling members could be formed of plastics and can be formed by plastic moulding.
  • a user can extend each of the baffle members 150, 160 to a desired baffling level and the baffle member will stay in position by frictional engagement with the corresponding stays.
  • the baffle members can be fully retracted for storage, as shown in Fig. 2A.
