Definitions

  • the application relates to hair styling apparatus for styling a user's hair, for example for curling, straightening, for creating flicks or for creating volume in a user's hair, e.g. close to the root.
  • volume means changing the angle of the hair fibres relative to the scalp or gravity.
  • Volume is a term which is commonly used and can be created in different parts of the hair.
  • Figures 1a and 1b illustrate the creation of volume at, or close to, the roots of the hair fibres.
  • Figure 1a illustrates the natural angle that a user's hair fibres 12 make to the user's scalp 10.
  • Each hair fibre falls under gravity to make an acute angle of between 10 to 25 degrees to a user's scalp.
  • each hair fibre is roughly aligned with the vertical (i.e. with the direction of gravity).
  • each hair fibre 12 has now overcome the force of gravity in the root region of the hair fibre and is set approximately perpendicular to the user's scalp.
  • each hair fibre has an increased angle, in the region of the root, relative to the hair fibre without volume in Figure 1a .
  • hair stylers which aim to create volume in a user's hair.
  • hair dryers can be used with brushes; straighteners, curling tongs or wet line products can also be used.
  • Hot air brushes for creating volume are known from GB2294200 and CN203106087 .
  • a hair styling apparatus which manipulates a user's roots is also known from WO2011/055116 to the present applicant. Some of these devices demonstrate poor efficiency of heating a user's hair and thus a user does not experience a quick and easy method of creating volume. There is also a risk of a user burning their scalp with some known devices due to the need to get close to the roots of the user's hair to create the desired volume in the user's hair.
  • US 6354305 discloses a hair styling appliance comprising a handle portion and a heating portion with a dome-shaped heating zone for heating and styling hair, and a cooling portion with a cooling zone for cooling the hair thus styled, wherein the difference in temperature between the surface temperatures of the heating zone and the cooling zone amounts to at least 80 kelvin and, more particularly, 100 kelvin.
  • a hair styling device comprising a shaft with a comb-like shaped forming tool with a hair receptacle spaced from one another and arranged in a row from the shaft protruding prongs and with a heated molded part.
  • the circumferential direction of the shaft the prongs extend only over a partial circumferential area and a heat sink or a heat sink arrangement is arranged in the area not carrying tines in such a way that when the hair styling device is used, under exercising a rotary movement about the longitudinal axis of the shaft, the heated hair guided out of the hair receptacles contacts the latter.
  • US 5673710 discloses an appliance for treating hair, which is comprised of a handle section and a heatable hair treatment section.
  • the hair treatment section possesses an approximately tubular bristle mounting member which is assembled from two half shells. Projecting outwardly from one of the half shells are bristles, and the other half shell is equipped with rib members.
  • the radius of the cross section of the bristled half shell is smaller than the radius of the cross section of the ribbed half shell.
  • the applicant has recognised the need to create an improved hair styling apparatus for creating volume at a user's roots.
  • the present invention provides a hair styling apparatus as set out in claim 1 and a hair styling method as set out in claim 15. Preferred features are set out in the dependent claims.
  • hair styling apparatus comprising: a heating member having a heating contacting surface for heating hair in contact with the heating member; a cooling member adjacent to the heating member, wherein the cooling member has a cooling contacting surface for cooling hair in contact with the cooling member and the cooling member is cooled by an active cooling mechanism; thermal insulation between the cooling member and the heating member; one or more tensioning members which project from the heating member and which, in use, tension a user's hair; and a guard which at least partially surrounds the heating member and tensioning member and which is thermally insulated from the heating member.
  • a styling mechanism may be provided that houses the heating member and the cooling member and wherein the heating contacting surface is provided on an upper surface of the styling mechanism and the cooling contacting surface is provided on a lower surface of the styling mechanism.
  • the hair styling apparatus has a plurality of tensioning members which project from different portions of the heating member. These may be arranged in a regular pattern (such as in rows) or in a random pattern.
  • the plurality of tensioning members may comprise one or more rows of teeth or bristles. Each row of teeth or bristles may comprise a base portion and a plurality of teeth or bristles that attach to the base portion.
  • the heating member may comprise one or more channels, each channel for receiving a respective base portion, and a plurality of cavities provided in the heating contacting surface and extending into a channel and through each of which a respective tooth or bristle can be inserted to attach to the base portion provided in the corresponding channel.
  • the tensioning members are spaced apart from each other by between 5 mm and 10 mm - to prevent the user from touching the heating contacting surface.
  • the teeth or bristles will typically extend out from the heating contacting surface by between 6 mm and 50 mm, preferably between 8 mm and 40 mm. If the teeth or bristles are shorter than about 5 mm then they will not be able to tension the hair during use. Not all teeth or bristles need to be within this range and in some embodiments some teeth or bristles will extend away from the heating contacting surface or the cooling contacting surface by between 1 mm and 8 mm. These smaller bristles or teeth are preferably provided close to the boundary between the heating and cooling contacting surfaces and make it easier for the user to slide the longer hair tensioning bristles or teeth close to the roots of the user's hair.
  • the tensioning member (or when plural tensioning members are provided at least some of the tensioning members) may be made from a thermally insulative material, such as a plastics material.
  • the tensioning members may be made from a thermally conductive material such as metal or a ceramic material.
  • the active cooling mechanism may be arranged to draw or blow air along a longitudinal axis of the hair styling apparatus.
  • the tensioning member may tension the user's hair during heating and/or cooling the hair.
  • tensioning it is meant that the hair is gripped, pulled or otherwise placed under stress.
  • the tensioning member may tension (i.e. pull) the user's hair against the heating contacting surface to improve heat transfer into a user's hair while the hair is being heated.
  • the tensioning member may tension the hair to apply stress to a user's hair as the hair contacts the cooling contacting surface adjacent the heating contacting surface. In this way, the tension is provided at the point of styling the hair, for example, to create volume or to otherwise style the hair.
  • the guard provides a buffer between the heating contacting surface and tensioning element and a user's scalp to help a user to avoid burning their scalp when using the apparatus.
  • the guard may thus cover the hot side of the heating member.
  • the guard may comprise a plurality of spaced apart elements.
  • the spacing (or gap) between each element may be larger than the gap (or spacing) between each tooth in the tensioning element. This means that hair slips easily through the guard to be captured by, and tensioned, by the tensioning element.
  • Each element has a shape which tapers from a wider section adjacent the cooling member towards a narrower section adjacent the tensioning element. For example, each element may be teardrop shaped.
  • the guard is preferably connected to the cooling member, and is not in any contact with the heating member, to avoid heating the guard.
  • the function of the guard and the function of the tensioning member may be performed by a plurality of teeth or bristles that extend from the heating contacting surface.
  • At least one or both of the heating contacting surface and cooling contacting surface is curved, for example at least a part of a surface of a cylinder.
  • the curvature of the contacting surface(s) helps to change the angle of the user's hair.
  • the hair styling apparatus may be used to create an increased angle between a user's hair and a user's scalp and which overcomes at least part of the gravitational force. In this way, volume may be created near the scalp.
  • the tensioning member may have a plurality of spaced apart teeth or bristles with a gap between each pair of teeth or bristles.
  • the tensioning member may thus be termed a comb and the terms are used interchangeably within this application.
  • Each gap may be relatively small to provide tension on a user's hair.
  • Each of the plurality of teeth or bristles may have generally tapering shape which is widest adjacent the heating contacting surface. In other words, the shape may be generally triangular. This arrangement increases the surface area of the comb which is in contact with the hair thus increasing the heating into the hair - where the teeth or bristles are made of a thermally conductive material.
  • the tapering may be to a rounded point whereby the comb is relatively easy to insert into a user's hair.
  • the tapering shape may also assist in separating strands of a user's hair so that the user's hair is caught easily and hence tensioned in the gaps.
  • the tensioning member and hence each of the plurality of teeth or bristles may project generally perpendicularly to the heating contacting surface. This may increase usability.
  • the tensioning member may also be generally centrally mounted on the heating contacting surface. This may improve the heat transfer into a user's hair.
  • the tensioning member may extend along the length (i.e. longitudinal axis) of the heating contacting surface. This increases the surface area of the tensioning member which contacts a user's hair.
  • the thermal insulation may comprise at least one of, or both of, an air gap and an insulating material, e.g. aerogel.
  • the thermal insulation may extend along the length of both the heating and cooling members.
  • the insulating material may be positioned, laterally (i.e. along the shorter axis of the heating and cooling members), between the air gap.
  • the air gap may be small, e.g. a few millimetres but is sufficient to ensure no direct contact between the edges of the heating contacting surface and the cooling contacting surface.
  • the cooling member, heating member, thermal insulation and tensioning member may together form a styling mechanism which when used to create volume may be termed a volume styling mechanism.
  • the apparatus may further comprise a handle by which the user holds the apparatus.
  • the handle may be attached to the styling mechanism or may form a support for at least one (or all components) of the styling mechanism.
  • the handle may be hollow, e.g. a hollow cylinder.
  • the handle may house the active cooling mechanism.
  • An active cooling mechanism is one that draws or pushes heat away from the cooling member.
  • the active cooling mechanism may comprise a fan.
  • the fan may be mounted adjacent the cooling member and may blow or draw air over the cooling member to cool the opposite surface of the cooling member to the cooling contacting surface. The fan thus removes heat from the cooling member.
  • the active cooling mechanism may comprise a heat sink and at least one heat pipe connecting the heat sink to the cooling contacting surface. The heat pipes thus draw heat from the cooling member into the heat sink.
  • the heat sink may be mounted at the opposed end of the handle to the styling mechanism, e.g. at least the cooling member, to maximize the length of, and hence efficiency of, the heat pipe.
  • a fan may be mounted adjacent the heat sink to assist in cooling the heat sink.
  • At least one of the heating contacting surface and tensioning element has an operative temperature of approximately 185 degrees C.
  • the cooling contacting surface may have an operative temperature of between room temperature and 70 degrees C and preferably between room temperature and 45 degrees C.
  • the significant difference in temperature allows the hair to be heated above its glass transition temperature so that it can be styled and then the hair can be rapidly cooled to set the style.
  • This temperature difference can be achieved in part by the thermal insulation and the temperature across the insulation material and/or air gap may range from room temperature to 185 degrees C.
  • the temperature difference can also be achieved due to the active cooling. Where a fan is used, the air outlet temperature from the fan is preferably no higher than 40 degrees C and preferably no higher than 30 degrees C.
  • the guard may have an operative temperature of between room temperature and 60 degrees C and in most cases between room temperature and 45 degrees C. This may be achieved by connecting the guard to the cooling member and not to the heating member.
  • the tensioning element may be made from plastics, metal or ceramic. Where the tensioning element is made from a heat conducting material, it will transfer heat into a user's hair which helps with the heating process. Where the tensioning element is made from an insulating material, e.g. plastics, the tensioning member should tension the hair against the heating contacting surface to ensure adequate thermal transfer into the user's hair.
  • Figures 2a to 3 show a hair styling apparatus 1 which can be used, for example to style hair by curling, straightening, creating flicks or creating volume at a user's root.
  • the hair styling apparatus 1 may be used to create the increased change in angle relative to the user's scalp and which overcomes at least part of the gravitational force as shown in Figure 1b .
  • the apparatus 1 comprises a body 20 having a handle 22 at one end of the body for the user to hold the apparatus 1.
  • the apparatus 1 At the opposed end of the body 20 to the handle, the apparatus 1 comprises a styling mechanism 24 which when used to create volume may be termed a volume styling mechanism.
  • the styling mechanism 24 is generally tubular having a generally tear shaped cross-section.
  • the handle 22 is also generally tubular having a generally circular cross-section which is more comfortable for the user to hold.
  • the handle 22 is hollow and is formed from two pieces 220, 222 which are connected together. It will be appreciated that other methods for forming the handle can be used.
  • the styling mechanism 24 is shown in more detail in Figures 2c and 2e . It is generally elongate.
  • the styling mechanism 24 comprises a heating member having heater 26 which may be a ceramic heater plate.
  • the heater 26 heats a comb 30 which protrudes from a heating contacting surface 27 of the heater 26.
  • the comb 30 may be made from plastics, metal or the same material as the heater plate. Indeed, the comb 30 may be separate from the heater plate 26 and the heating contacting surface 27 or a single part may provide the comb 30, the heater plate 26 and the heating contacting surface 27. Both the heating contacting surface of the heater and the comb 30 contact and heat a user's hair in use; when the comb is made from a thermally conducting material.
  • the tensioning created by the comb 30 improves heat transfer into the hair by ensuring a better contact between the hair and the heating contacting surface 27.
  • the heating contacting surface 27 is a generally elongate curved arcuate surface.
  • the comb 30 comprises a plurality of teeth each of which projects from the heating contacting surface 27 (in this embodiment by about 15 mm) and is generally triangular in cross-section. This arrangement increases the surface area of the comb which is in contact with the hair thus increasing the heating into the hair.
  • the comb 30 also tensions and grips the hair to assist with styling and thus may be considered to be a tensioning member.
  • the apparatus 1 also comprises a cooling member 32.
  • the cooling member 32 has a cooling contacting surface 33 which is also an elongate curved arcuate surface, which contacts and cools the user's hair.
  • the cooling member 32 is cooled by a heat pipe 36 which draws heat from the cooling member 32 to a heat sink 38.
  • the heat pipe 36 comprises two separate generally parallel pipes 36a and 36b that each couple with a respective one of two channels 32a and 32b that extend along the length of the cooling member 32.
  • the heat sink 38 is then cooled by air blown (or drawn) by a fan 34 which cools to ambient temperature.
  • the fan 34, heat pipe 36 and heat sink 38 are mounted within the handle 22.
  • the heat sink 38 ensures that there is active cooling of the cooling member 32, i.e. actively draws heat away from the cooling member 32.
  • the heat sink 38 and heat pipe 36 should be made from a suitable thermally conductive material, e.g. extruded aluminium having a thermal conductivity of about 200w/m/k.
  • the styling mechanism 24 also comprises a guard 40 which provides a buffer between the heating contacting surface 27 and comb 30 and the user's scalp.
  • the guard 40 thus helps the user to avoid burning their scalp when using the apparatus 1.
  • the guard 40 comprises a plurality of spaced apart elements 41 which allow the user's hair to pass between adjacent guard elements 41 and contact the comb 30 and heating contacting surface 27.
  • the spacing between adjacent guard elements 41 is the same along the length of the styling mechanism 24 and is set so that a user cannot touch the heat contacting surface 27 or comb 30 with their fingers or scalp.
  • each spaced apart guard element 41 is a generally tear-shaped ring and is thus tapered from a wider portion adjacent the cooling member 32 to a narrower, pointed, portion above the comb 30.
  • the ring shaped guard elements 41 may not be completely closed and a small gap may be present on the underside of the apparatus 1.
  • the two ends of each guard element 41 slot into a channel 43 which runs along the length of the cooling member 32 to mount the guard elements 41 on the apparatus 1.
  • Each guard element 41 surrounds the heating member 26, comb 30 and at least part of the cooling member 32.
  • each guard element 41 may only be arranged around the heating member 26 as described below.
  • the guard elements 41 should be directly connected only to the cooling member 32 (or to some other portion of the apparatus 1 that is thermally insulated from the heating member 26) and not to the heating member 26 to avoid heat transfer into the guard.
  • Each guard element 41 is preferably made from a thermally insulating material, e.g. plastics.
  • the cooling member 32 may thus draw heat out of the guard 40.
  • the hair styling apparatus 1 also comprises end caps 42, 44 which define either end of the guard 40 and also define both ends of the styling mechanism 24.
  • the end caps 42, 44 hold separate the heating member 26 and the cooling member 32 so that they do not touch and are thermally insulated from each other.
  • a connector 46 connects the end cap 42 of the styling mechanism 24 to the handle 22. It will be appreciated that the end caps 42, 44 and connector 46 are merely one mechanism for supporting and connecting the styling mechanism 24 to the handle 22. Any suitable mechanism may be used.
  • Figures 3a to 3f show an alternative hair styling apparatus 1 which is similar to that shown in Figure 2a and thus elements in common have the same reference number.
  • the apparatus 1 comprises a body 20 having a handle 22 at one end of the body 20 for the user to hold the apparatus 1.
  • the handle 22 has a button 126 for turning the apparatus 1 on and off.
  • the apparatus 1 comprises a styling mechanism 124.
  • a vent portion122 is provided through which the fan 34 can draw air into the styling mechanism 124 to cool the cooling member.

  • the comb 130 comprises a plurality of triangular shaped teeth which are grouped in threes and which extend from the heating contacting surface by about 20 mm. Between each group of teeth, there is a guard element 141. As before, the spacing between the elements is narrower in the comb 130 than in the guard 140. In this embodiment, each guard element 141 is generally arched.
  • a fan 34 is mounted mid-way along the body of the apparatus 1 adjacent the vent portion 122.
  • the fan 34 is located at the handle end of the styling mechanism 124.
  • Figure 3c is a perspective view of the styling mechanism 124 with the comb 130 and guard 140 removed for clarity.
  • the air flow from the fan 34 is shown by the arrows that extend along the styling mechanism 124.
  • the fan 34 blows air along the styling mechanism 124 and in particular across the cooling member 32 to actively cool the cooling member.
  • An air outlet is provided at the opposite end of the styling mechanism 124 to the fan 34.
  • the air may be arranged to exit through a junction between the heating member and the cooling member. In this way, stagnant hot air which may accumulate around the styling mechanism 124 is regularly blown away.

  • the fan is mounted at an angle to the longitudinal axis of the handle.
  • the fan 34 could be mounted at the far end of the handle, i.e. adjacent the power inlet. Regardless of the orientation of the fan 34, it is preferably arranged to blow or to draw the cooling air axially along the styling mechanism 24.
  • Figures 3e and 3f show a cross-section about half-way along the styling mechanism 124 and at the fan end of the styling mechanism 124. These Figures show the generally triangular cross-section of each tooth of the comb 130 and the arched shape of each guard element 141 of the guard 140. Each guard element 141 has a thicker region at the apex of the arch compared to the ends of the arch which connect to a thermally insulative support frame 125 of the styling mechanism 124.
  • two thermal insulation layers 128, such as aerogel layers are also provided together with an air gap 129 in order to separate the cooling member 32 from the heater 26 to reduce the risk of the heater 26 transferring heat into the cooling member 32.
  • the cooling member 32 has a plurality of fins 131 projecting inwards from the generally curved cooling surface, to assist with heat transfer away from the cooling member 32, e.g. to increase the surface area so that air from the fan 34 cools the cooling member.
  • the heater 26 heats a heating surface 127 which has a generally curved surface.
  • FIG 4 is a schematic illustration of a simplified version of the hair styling apparatus 1 of Figure 2a or Figure 3 in use next to a user's head.
  • the styling mechanism comprises a heater 326 which heats a heating contacting surface 327 and a comb 330 which contacts and heats the user's hair in use.
  • the styling mechanism also comprises a cooling member 332 which cools the user's hair after it has been heated and tensioned.
  • the cooling member 332 is actively cooled by a cooling mechanism 342 which may be a heat sink and/or fan as previously described or another mechanism to actively draw heat away from the cooling member 332.
  • There is also a guard 340 which helps control the user's hair and keep the heater a safe distance "d" from the user's scalp.
  • the hair is heated close to the root but neither the heating contacting surface 327 nor the comb 330 touch the user's scalp.
  • the comb 330 helps to apply tension to the hair (by gripping the hair) which helps to impart the stress to the root of each hair fibre needed to "volumise" the hair. Tensioning the hair also helps transfer heat from the heating contacting surface 327 into the hair. As the user lifts and rotates the apparatus 1, the tensioned hair comes into contact with the cooling member 332, which cools the hair and retains the hair's new form (with root lift).
  • Arrow A indicates the typical direction of movement to create volume which is illustrated and described in more detail below with reference to Figures 5 and 6 .
  • Figure 5 shows the change in hair temperature and stress as the apparatus 1 is moved through the user's hair and Figures 6a to 6g illustrate the movement of the apparatus 1 through the user's hair.
  • Figures 6a and 6b initially the user guides the apparatus 1 under the hair section which is to be styled and close to the user's scalp.
  • the tear-dropped shape of the guard assists with sliding the apparatus 1 under the user's hair because the pointed tip of the guard is relatively easy to insert.
  • the hair is not yet in contact with the heating contacting surface or the comb and thus the hair temperature remains constant at a little above ambient temperature as shown in Figure 5 to the left of the line 1.
  • both the slower and faster rates of use are able to ensure that the hair is heated to above the glass transition temperature and zone 3 of Figure 5 is entered. It may be advisable for the user to hold the apparatus 1 in the position shown in Figure 6c for a short period to allow the hair to heat up sufficiently to perform good styling.
  • the stress on the hair increases during zone 3 and remains high throughout zone 4 in which the hair is cooled.
  • zone 3 the user has turned the styling apparatus 1 to the position shown in Figure 6d - where the roots of the hair are now in contact with the cooling member.
  • the comb is still providing tension on the hair to impart the necessary force to stress and style the hair and the cooling member cools down the hair to set the style in place.
  • Figure 5 the increase in stress occurs at the transition between heating and cooling to form the style.
  • the rate of cooling is greater with the slower rate of use and will typically set the style better.
  • the slower rate of use ensures that the hair rises further above the glass transition temperature and that there is a large temperature drop during the cooling stage. Accordingly, a slower rate of use will typically result in increased performance or greater styling results.
  • Figures 6e to 6g show how the apparatus 1 is turned and then drawn across the rest of the user's hair.
  • the apparatus 1 can be used to create different shapes and styles in the rest of the hair.
  • the hair could be straightened by tensioning the hair straight across the heating contacting surface.
  • waves, curls or flicks can be formed by curling the hair around the heating contacting surface and cooling across the curved cooling surface of the cooling member as shown in Figure 6h . Crimping could also be achieved with a suitable arrangement of apparatus 1.
  • FIGs 7a to 7c schematically illustrate a further alternative apparatus 1 for styling hair comprising a styling mechanism 724 having a cooling member 732, a comb 730 and a heat contacting surface 727 which heats the user's hair.
  • the apparatus 1 also includes a guard which is not shown for convenience.
  • the cooling member 732 is actively cooled by the fan 734 which, as shown in Figure 7b , blows air across the inner surface of the cooling member 732 to cool the cooling member, for example to remove heat transferred into the cooling member by the user's hair.
  • the fan 734 is mounted within the handle 722 adjacent the styling mechanism. Thus the fan 734 is generally centrally mounted within the apparatus 1.
  • the cooling system may thus be more compact than that illustrated in the first embodiment and thus the overall device may be smaller, lighter and cheaper to manufacture.
  • Figure 7d shows how the styling mechanism used in Figure 2a is also adjusted in this embodiment. It will be appreciated that the change of cooling system and the change to the styling mechanism are independent of each other and either may be used in any of the other embodiments.
  • the styling mechanism comprises a heater 726 which may be a ceramic heater plate.
  • the heater 726 may also comprise a thermistor and thermal fuse for heat input and regulation.
  • the heater 726 heats a heating contacting surface 727 which contacts and heats the user's hair in use.
  • the heating contacting surface 727 should be made from a material which effectively transfers heat from the heater 726 into the user's hair.
  • the heating contacting surface 727 may be a surface of an extruded aluminium member having a thermal conductivity of about 200w/m/k.
  • the shape of the heating contacting surface 727 and the shape of the comb 730 are slightly different to those used in Figure 2a and are formed as two separate components which are then assembled together.
  • the heating contacting surface 727 is formed by the upper surface of a heating contacting member 747 that has a relatively large surface area to contact the user's hair during use, in order to improve heat transfer.
  • the comb 730 is mounted within a central channel 749 formed in the heating contacting member 747. In this arrangement, the comb 730 is generally planar with a plurality of teeth projecting generally perpendicular to the heating contacting surface 727 by about 20 mm.
  • the teeth are generally triangular in cross-section but the angle between the sloping slides of the triangle is more acute than in the arrangement of Figure 2a .
  • the time that the hair contacts and is tensioned by the comb in Figure 7d is shorter than that in the embodiment of Figure 2a .
  • a larger angled triangle may be preferable.
  • the comb is tapered to be wider closer to the heating contacting surface 727 to create a longer path for tensioning hair whilst it is being heated.
  • the embodiments preferably include thermal insulation and an air gap between the heater and the cooling member. These are most clearly seen in Figure 7d in which the thermal insulation 750 is mounted between the heater 726 and the cooling member 732.
  • the thermal insulation 750 extends along the length of the styling mechanism and is made from an insulating material such as aerogel. Further insulation is achieved by providing an air gap 736 which extends along the length of the styling mechanism either side of the thermal insulation 750 and between the edges of the heating contacting member 747 and the cooling member 732. In this way, there is no direct contact between the heating contacting member 747 and the cooling member 732.
  • the cooling member 732 of Figure 7d also has a plurality of fins 731 which project inwards.
  • the use of the fins 731 increases the surface area for cooling by the air blown from the fan 734. Waste heat from the cooling member 732 is conducted through the fins into the ducted air flow between the fins. This heat is then removed by the ducted air flow as it exits an air outlet (as shown in Figure 7c ).
  • FIGS 8a to 8c schematically illustrate a further alternative apparatus 1 for styling hair.
  • the apparatus 1 has a number of bristles 801 extending from a heating contacting surface 827 which heats the user's hair.
  • the bristles 801 are arranged in longitudinal rows that are spaced apart from each other around the arcuate heating contacting surface 827.
  • the spacing between bristles in the same row and between the bristles in adjacent rows is between 5 mm and 10 mm and preferably about 8 mm, to prevent the user touching the heat contacting surface 827 with their scalp or their finger.
  • the bristles 801 are made of a thermally insulative material, such as plastic. Due to the spacing between the bristles 801 and the thermally insulative material from which they are made, the bristles 801 perform the dual functions of the comb and the guard of the previous embodiments.
  • the hair styling apparatus 1 has the overall appearance of a conventional hair brush and is easier to use as the user does not need to angle an apex of the device under their hair. They can instead use the apparatus like a conventional hairbrush.
  • the handle 822 houses a fan 834 which is used to force air past the cooling member 832 and out through the air outlet 803 (or in through the air inlet 803 past the cooling member 832) to keep the cooling member 832 cool.
  • Figure 8d is a cross sectional view of the styling mechanism 824, showing the heating contacting member 847 and the cooling member 832 which are both supported by a thermally insulative supporting frame 825.
  • the supporting frame 825 also provides a roof over the cooling member 832 - so that air drawn past the cooling member 832 by the fan 834 is kept away from the heater 826.
  • a heat insulating layer 850 is provided between the heater 826 and the cooling member 832 to minimise heat transfer from the heater 826 to the support frame 825 and from there to the cooling member 832.
  • Figure 8d also shows a second (optional) insulating layer 850' (which may also be an aerogel layer) that is provided between the insulative frame 825 and the cooling member 832.
  • Figure 8d also shows that in this embodiment, the heating contacting member 847 has seven rows of bristles 801 and the supporting frame 825 has two rows of bristles 801; and that the length of the bristles 801 varies from a maximum length of about 35 mm at the apex of the heating contacting surface 827 to a shortest length of about 8 mm for the bristles 801 mounted on the supporting frame 825, thereby giving the apparatus 1 an overall elliptical shape.
  • the bristles 801 may also be arranged to extend out from the cooling member 832 such that bristles are provided right around the circumference of the styling mechanism 824.
  • the bristles 801 are preferably flexible. This is because fixed (rigid) bristles catch on tangles in the user's hair and do not absorb or reduce the force applied to the hair, which makes the device feel harsh and damaging to the user and can result in excessive force being applied to the user's hair.
  • Figure 9a illustrates the case where each bristle 801 is mounted within a flexible base so that the whole bristle can move in response to force on the hair; and
  • Figure 9b illustrates an alternative arrangement, in which an upper part of each bristle 801 can flex and thus absorb at least some of the forces applied through the device to the user's hair.
  • still bristles 801 may be provided that have both a flexible base and a flexible upper part.
  • FIGs 10 and 11 illustrate two ways in which the bristles 801 may be mounted within the heating contacting member 847.
  • the heating contacting member 847 (which may be formed as an aluminium extrusion) is provided with elongate channels 851 into each of which a pre-assembled or co-moulded row of bristles 801 is slid.
  • Each row of bristles 801 includes a base portion 853 and the individual bristles 801, both of which can be made from plastics material.
  • Each channel 851 narrows towards an open end at the heating contacting surface 827 and the base portion 853 is shaped to dovetail with the channel 851 so that the base portion 853 can only be removed from the heating contacting member 847 from the edge thereof and not through the open end of the channel 851 on the heating contacting surface 827.
  • Figure 10a shows the individual components of the heating contacting member 847, the base portion 853 and the individual bristles 801.
  • Figure 10b illustrates the way in which the assembled row of bristles 801 is inserted into a channel 851; and
  • Figure 10c illustrates the heating contacting member 847 with the row of bristles inserted therein.
  • Figure 11 illustrates an alternative arrangement which provides a more uniform heating contacting surface 827.
  • the heating contacting member 847' has a smooth surface with internal cavities 855 arranged in rows. Channels 851 are also provided under the rows of cavities 855 to receive the base portion 853.
  • the base portion 853 is slid within the channel 851 of the heating contacting member 847' (as illustrated in Figure 11a ) and then the individual bristles 801 are inserted into the base portion 853 through the cavities 855 in the surface of the heating contacting member 847' (as illustrated in Figure 11b ).
  • each bristle 801 is slightly smaller in diameter than the cavity 855 to provide space for the bristle 801 to flex and move relative to the heating contacting member 847'.
  • the arrangement shown in Figure 11 is preferred over the arrangement shown in Figure 10 as it provides for a more uniform heating contacting surface and also provides less space in which debris and hair product can accumulate.
  • illustrative operational temperatures are approximately 185 degrees C for the heater, heating contacting surface and preferably also for the comb; although it is appreciated that the temperatures will depend on the materials being used.
  • Both the guard and the cooling member are preferably at a much lower temperature, with the guard having an operating range of room temperature to 60 degrees C and the cooling member having an operating range of room temperature to 70 degrees C.
  • the upper end of the target temperature range for the cooling member is preferably 45 degrees C to provide effective setting of the hair style.
  • the temperature across the insulation and/or air gap will range from room temperature to 185 degrees C.
  • the air outlet temperature from the fan is preferably no higher than 40 degrees C. Both the temperature of the cooling member and the air outlet will depend on the duty cycle of the fan.
  • the teeth or bristles will typically extend out from the heating contacting surface by between 6 mm and 50 mm, preferably between 8 mm and 40 mm. If the teeth or bristles are shorter than about 5 mm then they will not be able to tension the hair during use. Not all teeth or bristles need to be within this range and in some embodiments some teeth or bristles will extend away from the heating contacting surface or the cooling contacting surface by between 1 mm and 6 mm. These smaller bristles or teeth are preferably provided close to the boundary between the heating and cooling contacting surfaces and make it easier for the user to slide the longer hair tensioning bristles or teeth close to the roots of the user's hair.
  • the heating contacting surface and the cooling contacting surface were formed on upper and lower surfaces of a generally tubular body portion.
  • the heating contacting surface and the cooling contacting surface may be provided next to each other in a side by side arrangement on a generally flat body portion.
