Definitions
- the present invention relates to the field of hairdressing accessories and in particular heated hairdressing accessories extending longitudinally along an axis between a proximal end and a distal end, said accessory comprising an at least partially hollow grip tip extending longitudinally. along and around the axis and assembled on said distal end, said grip end being designed to be grasped by the user of the accessory.
- Many hairdressing devices are known to blow hot air to allow users to dry the hair and / or shape it.
- the pouters (or "curlers" according to the English expression) which have a handle and a heating mandrel, generally cylindrical.
- the mandrel can be fixed with respect to the handle or mobile in rotation and motorized with respect to the handle.
- the user of the device is forced to turn the handle, and therefore his hand, of the device to wrap the hair around the mandrel.
- the rotation of the mandrel is motorized and the user does not have to turn his hand.
- the mandrel is heated to a high temperature (of the order of 100 ° C. to 250 ° C. so that it is impossible for the user to touch this mandrel. Consequently, the user is forced to use the hair styling device with one hand which makes the hair styling operation difficult and will tire the user quickly, especially if his hair is long.
- patent application US4695704 proposes a gripping endpiece which remains fixed despite the rotation of the mandrel, which makes it possible to constitute a point of support against a first hand of the user, while the other hand rotates the handle integral with the mandrel in order to wind the hair around the mandrel.
- This known solution is generally satisfactory as long as the user applies only axial forces.
- the end piece proposed by this document cannot remain independent in rotation with respect to the accessory in the event of the presence of a radial force given its limited rotation guidance.
- the mandrel can comprise a plurality of bristles or pins, in the manner of a brush (this is called a rotary brush).
- a rotary brush the manner of a brush
- the gripping end piece will then become integral in rotation with the mandrel, which will exert unpleasant friction on the user's hand.
- this type of device is sometimes used by users to perform hair straightening.
- the user must manipulate the device from the scalp to the tips of the hair, applying a fairly substantial traction on the latter in order to smooth it.
- the radial force applied to the mandrel and to a possible gripping tip is then significant, and the known gripping tips tend to block and become integral with the mandrel or the brush.
- the known end-piece mentioned previously can detach from the mandrel, which risks causing burns risks for the user.
- An objective of the invention is to provide a hair styling device which is particularly simple and intuitive to use.
- An objective of the invention is to provide a hairstyling device that is particularly comfortable to use, regardless of the mode of use of the hairstyling appliance.
- Another object of the invention is to provide a hairstyling device which is particularly safe to use.
- Another objective of the invention is to provide a hair styling device which is particularly compact and ergonomic.
- Another objective of the invention is to propose a hairstyling device which is particularly reliable and robust.
- Another objective of the invention is to provide a hairstyling device which is inexpensive and simple to manufacture.
- a heated hairstyling accessory extending longitudinally along an axis between a proximal end and a distal end
- said accessory comprising an at least partially hollow grasping tip extending longitudinally along and around the axis and assembled on said distal end, said grip end being designed to be grasped by the user of the accessory, characterized in that the grip end is free to rotate relative to the accessory and in that that the distal end extends inside and in contact with the grasping tip longitudinally along the axis, the distal end ensuring a first guide in rotation of the grasping tip relative to the accessory in a plurality of points along the axis.
- heating styling accessory any accessory capable of transferring heat to the hair, whether by convection, conduction or radiation, or the like.
- the accessory can be passively heated, that is to say that it does not have any element producing heat in its own right: the accessory is then heated thanks to the heat that it receives, for example from a hot fluid passing through it.
- the accessory can also be actively heating, that is to say that it itself has an element producing heat in its own right, such as an electrical resistance.
- gripping tip any element allowing the user to handle the heating accessory without the risk of burning or discomfort.
- the grasping tip is substantially cold, that is to say that it is isolated from the heated hairdressing accessory so as to remain at an acceptable temperature so that it can be handled directly by hand.
- the temperature of the grip tip does not exceed 40 ° C to 50 ° C.
- distal and proximal can preferably be understood in relation to a direction of flow of a fluid which would pass through the accessory, as will be detailed later.
- the invention aims to propose a gripping endpiece which is mounted in rotation, that is to say in rotation, relative to the accessory with an optimized rotation guide.
- the distal end which extends inside and in contact with the grasping tip makes it possible to multiply the points of contact between said distal end and the grasping tip along the longitudinal axis, which allows to improve the guidance in rotation, in particular by avoiding the phenomenon of bracing which could appear in the event of radial forces applied to the gripping end piece, when the guidance in rotation is carried out at only one point , as is the case in known devices.
- the invention thus notably makes it possible to remarkably facilitate the use of hairdressing devices, and in particular hairdressing devices of the rotary brush or pouting type, by allowing the user to safely grasp the grip tip which remains cold. (or at least at a completely acceptable temperature to be able to be grasped directly by hand) the gripping tip remaining fixed in his hand despite the rotation of the mandrel or the brush and despite the presence of significant radial forces.
- radial force or radial forces is meant one or more forces which are oriented in a radial direction to the mandrel or to the brush, that is to say along a radius of the mandrel if the latter has a form of revolution, or alternatively substantially perpendicular to its longitudinal axis, that is to say its axis of revolution or rotation.
- an axial force is a force oriented along the longitudinal axis of the mandrel or the brush.
- the hairdressing accessory is intended to be removably assembled on a hairdressing appliance, and more precisely on the main body of this hairdressing appliance, as will be detailed below.
- said accessory is designed to be, after assembly on the main body, driven in rotation by the hairdressing appliance, in order to give the accessory a rotational movement relative to the hairdressing appliance, and therefore also by compared to the grip.
- the hair styling device and the attachment grip of the accessory remain stationary while the accessory is rotating.
- the proximal end is intended to be assembled with the main body, that is to say to be mounted on the main body as will be detailed later.
- the contact between the grasping tip and the distal end of the accessory is a surface or linear contact, that is to say a continuous contact. We can then speak of an infinity of contact points.
- the contact between the grasping tip and the distal end comprises a plurality of distinct and different point contact points, for example by using balls interposed between the two parts.
- the gripping endpiece comprises a substantially cylindrical cap and the distal end comprises a circular guide rib extending longitudinally along the axis XX 'inside and in contact with said cap so as to define a contact surface cylindrical between the grip and the accessory.
- the guiding in rotation of the gripping end piece with respect to the accessory is achieved by means of a sliding pivot connection consisting of two cylinders nested one inside the other. This construction allows large radial forces to be absorbed, including if these are applied cantilevered, that is to say outside the zone carrying out the guiding in rotation, for example at the end. free from the grip.
- the cylindrical contact surface between the gripping end piece and the accessory, or more precisely between the gripping end piece and the distal end, or even according to the preceding preferred embodiment, between the cap and the guide rib has a length between 2 mm and 15 mm, advantageously between 4 mm and 10 mm and is preferably equal to 6 mm. These dimensions have been carefully studied to ensure good guiding in rotation while limiting the size of the device. In addition, such a cylindrical contact surface ensures good heat exchange between the distal end and the gripping end piece.
- the accessory is a hollow accessory forming an air circulation chamber, said proximal end comprises an air inlet and said distal end comprises a plug.
- the air inlet then allows air to enter the interior of the accessory while the cap prevents air from escaping axially from the accessory and forces the latter to exit through radial openings.
- the plug is then mounted fixed relative to the accessory, by any suitable means, such as by clipping, screwing, gluing, welding, etc. Consequently, the gripping end piece is therefore movable in rotation relative to the plug.
- the plug is mounted movable in rotation relative to the accessory, so that in this case, the gripping end piece can be mounted fixed vis-à-vis of the plug.
- the distal end comprises a rotational drive device designed to transfer a rotational movement from a hairdressing appliance on which the accessory is installed to the accessory.
- the distal end is designed to receive a torque from a hairdressing appliance and transfer this torque to the accessory, in order to give the latter a rotational movement.
- the plug has a shape of revolution around the axis and the rotary drive device extends longitudinally along the axis through the plug. It is then the plug which comprises the rotary drive device and will transmit the torque to the accessory.
- the rotary drive device extends over the entire length of the plug, that is to say that it passes right through it.
- the rotary drive device has grooves.
- other means of rotational drive such as for example a key, a pin, or even a particular form of bore such as for example a bore of square, rectangular, cruciform section, etc. .
- said accessory comprises an axial holding device designed to prevent any relative translation between the gripping end piece and the distal end.
- the gripping tip cannot move longitudinally relative to the accessory, which in particular makes it possible to avoid any unexpected disassembly of the gripping tip of the accessory.
- this also makes it possible to be able to manipulate the accessory only by means of the grasping tip, including during the operations of assembling and disassembling a hairstyling device, which is very useful when the accessory is still hot.
- the axial holding device forms a second guide in rotation of the gripping end piece relative to the accessory, for example by proposing a guide of pivot link type, which makes it possible to improve the guide in rotation of the grip tip relative to the accessory.
- the gripping endpiece is guided in rotation in two different and distinct places along the longitudinal axis, which allows the gripping endpiece to absorb significant radial forces while remaining perfectly mobile and guided in rotation with respect to the accessory.
- the axial holding device comprises a circular ring integral with the gripping end piece and disposed in a circular guide groove within the plug.
- the gripping endpiece comprises a movable attachment device between an open position designed to allow the assembly or disassembly of the accessory on a hairdressing appliance and a closed position designed to keep the assembly assembled. accessory with the hairdressing appliance.
- the gripping endpiece as defined by the invention can preferably also perform an assembly function of the accessory on a hairdressing appliance. This grouping of rotation guidance and assembly functions within the grasping tip is entirely clever since it makes it possible to be able to assemble or disassemble the accessory of a hairdressing appliance, including when this accessory is still hot and therefore cannot be handled directly by hand.
- the closed position is advantageously a rest position.
- the attachment device naturally returns to the closed position, which permanently guarantees the correct assembly of the accessory on the hairdressing appliance.
- the gripping endpiece may include a locking button making it possible to move the attachment device between its open and closed positions.
- the locking button can be a push button or a lever making it possible to act directly and mechanically on the hooking device, and this very intuitively for the user.
- the attachment device advantageously forms a guide in rotation between the gripping endpiece and a hairstyling device, which makes it possible to further improve the quality of the guiding in rotation of the gripping endpiece, in particular by strengthening its resistance to radial forces.
- the gripping end piece has a gripping relief, which makes it possible to prevent the gripping end piece from slipping from the user's fingers.
- the accessory forms a tube intended to receive inside it preferably hot air, said tube comprising a radial air outlet for ejecting the air.
- the accessory also includes bristles or pins distributed over its entire external surface. The accessory thus forms for example a rotating brush.
- the invention also relates to a hairdressing appliance, such as for example a rotary blower brush, comprising an accessory as defined previously, said accessory being assembled with a main body of the hairdressing appliance.
- a hairdressing appliance such as for example a rotary blower brush
- Figure 1 is a perspective view of a hairdressing apparatus according to the invention, in this case a blower brush, the apparatus comprising in particular two different and interchangeable accessories, one of which is assembled and the other not .

- Figure 12 is a perspective view of the tip of Figure 1 1, some parts having been hidden.
- an accessory 2 is an accessory of an appliance which constitutes a rotary blower brush.
- This type of device well known as such, makes it possible to combine the operations of drying and styling the hair. Indeed, as will be described later, the device can simultaneously blow air, possibly heated beforehand, and grip and set in motion the hair in order to give it a shaping, and in particular a waving or a closure.
- the invention is in no way limited to this embodiment and can relate to any other hairdressing appliance, such as for example hair dryers, the construction, the problems and the challenges of which are described below are relatively relatives.
- upstream means “before” or “at the beginning”
- downstream means “after” or “at the end” by analogy with the hydraulic theme from which these expressions.
- proximal means “close to the air inlet” while the term “distal” means “remote from the air inlet”.
- the hairdressing apparatus comprises a main body 1 which itself advantageously comprises an external shell 12, preferably forming a grip zone for the user, such as for example a handle or a handle .
- a main body 1 which would not necessarily constitute a handle such as for example a barrel of hair dryer.
- the main body 1 extends longitudinally along an axis XX ′.
- the main body 1 has a shape of revolution around the axis XX ′, for example having the shape of a tube of circular section.
- the main body 1 could take the form of a tube of oval, square section, etc., the important thing being that the main body 1 is of hollow section to allow accommodating different components and the circulation of a air flow 3 as will be detailed later.
- an air flow 3 circulates inside the main body 1.
- This air flow 3 is set in motion by a motor-fan unit 13 disposed inside the main body 1 as can be seen in FIG. 5 or 6. More specifically, the air flow 3 is advantageously drawn in through an air inlet 1 1 preferably located at a proximal end of the main body 1.
- the air inlet 1 1 preferably comprises a first grid 1 1 1, advantageously removable to allow cleaning.
- the air inlet 1 1 further comprises a second grid 1 12, preferably fixed in order to enhance the operational safety of the device. Indeed, this second grid 1 12 makes it possible to prevent the hair from penetrating inside the main body 1, even in the absence of the first removable grid 1 1 1.
- the openings of the second grid 1 12 are preferably larger than those of the first grid 1 1, for example, the first grid 1 1 1 has a plurality of holes of small diameters uniformly distributed over the entire surface of the first grid 1 1 1, while the second grid 1 12 comprises a plurality of open angular sectors.
- the air thus circulates inside the main body 1 from the air inlet 1 1 to an air outlet 191 advantageously coaxial with the air inlet 1 1.
- the motor-fan unit 13 used in the embodiment illustrated by the different figures therefore makes it possible to generate and set in motion the air flow 3.
- the motor-fan group 13 comprises a propeller 131 which can be either an axial (or helical) propeller as illustrated, a centrifugal propeller, a helico-centrifugal propeller, or even a tangential propeller without departing from the scope of the invention.
- the propeller 131 is rotated by a motor 133 in a manner known as such.
- the hairdressing apparatus comprises a heating device 18 intended to heat the air flow 3. More specifically, the heating device 18 is arranged inside the main body 1, downstream of the motor-fan unit 13. Thus, the air flow 3 set in motion by the motor-fan group 13 is sucked in at ambient temperature through the air inlet 1 1 and then passes through the heating device 18 which has the effect of heating the air flow 3 in order to eject hot air on the hair of the user on the one hand to dry these and on the other hand to shape them.
- the heating device 18 comprises a support of mica 182, or of any other insulating material, in the form of a cross or an X as can be seen in FIGS. 5 and 6.
- the heating device 18 further comprises a conductive wire (not shown) wound around the support of mica 182. An electric current flows inside this wire which has the effect of producing heat by Joule effect, as is well known as such in hairdressing apparatus.
- the hairdressing appliance also includes a hairdressing accessory 2, generally removably mounted on the main body 1.
- the hairdressing apparatus comprises a plurality of accessories 2, for example two accessories, advantageously different from each other. It is thus possible for the user to choose which accessory he wants to use, according to the hair shaping he wishes, and to install it on the main body 1 of the device.
- Figure 1 illustrates two accessories 2 of different diameters, for example 38 mm and 50 mm, which allows to make waves or curls in hair of different diameters but also to adapt to the length of the hair of the user .
- the length of the accessories 2 does not vary and remains, for example, between 120 mm and 160 mm, for example being substantially equal to 140 mm.
- the accessory offers a useful length, that is to say a length intended to be in contact with the hair of the order of 100 mm.
- the hairstyle accessory 2 therefore extends longitudinally along the axis X-X ’between a proximal end and a distal end according to the preferred dimensions above.
- the accessory 2 is mounted movable in rotation relative to the main body 1 so as to be able to wrap the hair around the accessory 2 to give them a shaping, in particular a waving or curling.
- the accessory 2 is mounted coaxially with the main body 1.
- the accessory 2 comprises an air inlet 21 intended to cooperate with the air outlet 191 of the main body 1 so as to pass the air from the main body 1 to the accessory 2
- the proximal end comprises the air inlet 21.
- the accessory 2 also has a hollow shape, preferably a tube shape, thus defining an interior air circulation chamber.
- the air flow 3 coming from the main body 1 and set in motion by the motor-fan unit 13 can enter inside the accessory 2.
- the accessory 2 also comprises an air outlet 23 radial designed to eject the air radially, that is to say substantially perpendicular to the axis XX ′, as can be seen for example in FIG. 1.
- the accessory 2 forms a tube intended to receive inside it preferably hot air, said tube comprising a radial air outlet 23 for ejecting the air.
- the air outlet 23 includes a plurality of openings, in this case holes, the diameter of which can be variable depending on their position relative to the flow d 'air 3.
- the diameter of the different holes will be decreasing in the direction of the air flow 3: in other words, the holes with the largest diameter are located near the air inlet 21 while the smaller diameter holes are located opposite the air inlet 21, for example near a gripping end piece 24.
- the section openings of the air outlet 23 decreases according to the direction of flow of the air flow 3 within the accessory 2, which makes it possible to guarantee an optimal drying efficiency of the hair insofar as the reduction in the section of the air outlet openings 23 compensates for the pressure drop in the air flow 3 due to the increase in the distance from the fan-motor unit 13.
- the accessory 2 comprises an external mandrel 22, preferably made of heat conductive material such as a metallic material for example, in order to optimize the heat transfer to the hair, and thus improve the setting in shape.
- the air flow 3 is heated in the main body 1 by the heating device 18 and is then found inside the accessory 2 which it will heat.
- the external mandrel 22 then advantageously comprises the air outlet 23 described above.
- the accessory 2 is heated insofar as the air flow 3 which passes through it is itself heated by the heating device 18 as explained above.
- the external mandrel 22 of the accessory 2 will make it possible to diffuse the heat transmitted by the air flow 3 to the hair and therefore allow the accessory 2 to give the hair a shape.
- the main body 1 also advantageously comprises an accessory support 19 intended to receive and rotate one of said accessories 2.
- the accessory support 19 extends longitudinally and coaxially with the main body 1, from the air outlet 191 towards a distal end opposite to the air inlet 1 1.
- the length of the accessory support 19 is preferably substantially equal to the length of the accessories 2.
- the accessory support 19 advantageously comprises a casing 193 of substantially cylindrical shape.
- the accessory support 19 further comprises an engine group 196, visible in FIGS. 5 and 6, remarkably arranged inside the casing 193.
- the engine group 196 is arranged inside the accessory 2, more precisely in the interior chamber of the accessory 2.
- Said motor group 196 is then intended to set in motion the accessory 2 installed on the accessory support 19 so that the accessory 2 is driven in a rotational movement around the 'longitudinal axis XX' and relative to the main body 1.
- the power unit 196 comprises an electric motor 1961 and a transmission box (or gearbox) 1962, as can be see in Figure 10.
- the 1962 gearbox is then coaxial and mounted at the end of the 1961 electric motor.
- the 1962 gearbox is designed to reduce or modify the rotational movement of the 1961 electric motor, and more particularly to reduce its rotational speed while increasing its torque, as is well known as such, thus advantageously forming a geared motor.
- the accessory support 19 preferably comprises, at its distal end, a rotary drive device 194 intended to correspond with a device for receiving the accessory 2 in addition to transmit the torque from the engine group 196 towards the accessory 2.
- the rotary drive device 194 comprises for example grooves which correspond with grooves arranged inside the gripping end piece 24 of the accessory 2.
- the accessory support 19 advantageously comprises a coupling device 195 situated at a distal end of the accessory support 19 which comprises for example a groove or a circular groove produced on a motor shaft 197.
- the accessory support 19 advantageously comprises a device 192 for guiding the air flow 3 which extends longitudinally from the air outlet 191 and opposite the inlet air 1 1.
- This guide device 192 may for example include ribs or arches.
- the guide device 192 is integral with the main body 1.
- the guide device 192 is mounted substantially end to end with the heating device 18, without however being in contact with the latter so that the guide device 192 is not deteriorated by heat.
- the main body 1 also comprises a control and supply device 16 as can be seen for example in FIG. 4.
- this control and supply device 16 comprises in particular a speed switch 161 allowing the user to control the speed of rotation of the motor 133 and therefore the speed of flow of the air flow 3.
- this speed switch 161 is located near the air inlet 1 1 and of the motor 133 and can take the form of a sliding switch with several positions.
- the main body 1 can also include a rotation switch 162 allowing the user to select the direction of rotation of the power unit 196 and therefore to control the direction of rotation of the accessory 2 which it will have previously mounted on the accessory support 19 as described above.
- This rotation switch 162 also makes it possible to control the starting or stopping of the motor unit 196 and therefore the turning or stopping of the accessory 2.
- the selection of the direction of rotation of accessory 2 allows the user to choose which direction will be the ripples or curls that he will create on his hair.
- the rotation switch 162 is arranged near the air outlet 191, that is to say near the accessory 2 so as to be easily actuated by the thumb of the user which allows the latter to precisely control the rotation and stopping of the motor unit 196 and therefore the rotation and stopping of the accessory 2 during its styling operation.
- the main body 1 also advantageously comprises a rotary cord 163 which allows the cord to rotate freely. power supply within the main body 1, therefore not impeding the movements of the user.
- This device is well known as such, so it is not detailed here.
- the accessory 2 has a cold endpiece 24, 25 designed to stay at a temperature preferably not exceeding the ambient temperature of 50 ° C and ideally not exceeding the ambient temperature of 5 ° C to 15 ° C which allows the user to be able to handle this cold nozzle directly by hand without the risk of getting burned.
- the cold end piece 24, 25 is therefore intended to be grasped by the user of the hairdressing apparatus, advantageously having a temperature between 20 and 50 ° C, preferably around 30 ° C.
- the cold end piece 24, 25 extends at least partially around the power unit 196 and more preferably around the gearbox 1962.
- at least part of the motor group 196 preferably at least part of the gearbox 1962, is arranged inside the cold end piece 24, 25.
- the power unit 196 and the cold end piece 24, 25 overlap on a certain length, which gives the motor unit 196 a cooling zone.
- the 1962 gearbox and the cold end piece 24, 25 are overlap over a certain length, which gives the 1962 gearbox a cooling zone.
- the engine group 196 and preferably the gearbox 1962, can then dissipate its calories, including the calories received by the flow of hot air 3 which circulates inside the accessory 2 and around the engine group 196 by through this cold end piece 24, 25.
- the heat exchange surface between the power unit 196 and the open air is thus increased by the overlap of the power unit 196 and the cold end piece 24, 25.
- the power unit 196 heats less, which can improve its reliability and its lifespan.
- the heat exchange surface between the gearbox 1962 and the open air is thus increased by the overlap of the gearbox 1962 and the cold end piece 24, 25.
- the gearbox 1962 heats up less, this which allows the lubricant it contains to retain all its properties and therefore to properly lubricate the gears of the gearbox 1962. The life of the latter is therefore improved, as well as its performance. In addition, the noise emitted by the latter can also be reduced and the risk of lubricant leakage is minimized.
- the cold end piece 24, 25, the power unit 196 and the accessory 2 are all coaxial, and more specifically, the power unit 196 is inside a chamber interior of the accessory 2.

- the cold end piece 24, 25 comprises two separate sub-assemblies: a gripping end piece 24 and a plug 25, the constructions of which are detailed below.
- the cold end piece 24, 25 advantageously constitutes one end of the hairdressing appliance.
- the distal end of the accessory 2 comprises a plug 25, that is to say a piece whose function is preferably to plug or close the distal end of the accessory 2, in particular in order to make this end tight vis-à-vis the air flow 3.
- the plug 25 then forces the air flow 3 to take another outlet to leave the accessory 2, in this case the radial air outlet 23 as defined above.
- the plug 25 advantageously has a shape of revolution around the axis XX ′, and more particularly a substantially cylindrical shape as can be seen in FIGS. 7 to 12. In fact, such a shape is particularly suitable for rotation of the hairdressing accessory 2 as represented by the illustrated embodiment, namely an accessory 2 of a rotary blower brush.
- the plug 25 preferably comprises a first part 251 intended to be mounted on the accessory 2.
- the plug 25 is preferably mounted fixed relative to the accessory 2, by example using a plurality of latching tabs 251 1 intended to come into contact with the tube of the accessory 2.

- the distal end of the accessory, more precisely the plug 25 advantageously comprises a circular guide rib 254, that is to say the generator of which is a circle, which extends longitudinally along the axis XX ' .
- the plug 25 advantageously comprises a rotary drive device 255 designed to transfer a rotational movement from the hairdressing appliance on which the accessory 2 is installed to the accessory 2.
- the rotational drive device 255 is then intended to correspond with a complementary rotational drive device 194 belonging to the main body 1 of the hairdressing apparatus, as will be detailed later. More specifically, the rotational drive device 255 comprises grooves, as illustrated, which correspond with other grooves of said complementary device 194.
- Such a device allows the plug 25, that is to say at the distal end, to be able to drive the accessory 2 in rotation from the main body 1 of the hairdressing appliance.
- the rotary drive device 255 extends longitudinally along the axis XX ′ through the plug 25, which allows the rotational drive torque to be well distributed over at least part of the length of the plug 25. This also makes it possible to increase the potential heat exchange surface between the complementary device 194 integral with the motor group 196 and the plug 25, and therefore indirectly the cooling of the motor group 196.
- the first part 251, the tongues 251 1, the guide flange 252, the guide groove 253, the guide rib 254 or even the complementary drive device 255 are coaxial to the axis XX 'and preferably have forms of revolution around the axis XX'.
- the plug 25, and more precisely the first part 251 extends at least partially around the motor unit 196, so as to allow the latter to cool as explained above.
- the first part 251 extends around the power unit over a length of between 1 mm and 50 mm, advantageously between 2 mm and 15 mm and is preferably equal to 6 mm.
- the plug 25 is in contact with the enveloping casing 193 and in contact with the motor unit 196 which therefore allows heat exchange between the plug 25 and the motor unit 196, via the casing 193.
- the accessory 2 includes a gripping tip 24 allowing the user to grasp the accessory 2 even when the latter is in motion.
- this gripping nozzle is coaxial with the main body 1 and opposite the air inlet 1 1 of the latter which allows good ergonomics of the device.
- the gripping tip 24 is at least partially hollow and extends longitudinally along and around the axis XX '.
- the grip end 24 comprises a substantially cylindrical cap 241.
- this shape has ergonomic and economical qualities, in particular with regard to its ease of manufacture.
- the gripping end piece 24 is assembled on the distal end of the accessory 2, and more precisely on the plug 25 defined above.
- the gripping tip is therefore designed to be grasped by the user of the accessory while being free to rotate relative to the accessory 2, which, as explained, allows the user to grasp said tip firmly with his fingers. grip without getting burned and despite the rotation of the accessory. Indeed, the free rotation of the gripping end piece with respect to the accessory 2 makes it possible to avoid any risk of friction between the hand of the user and the gripping end piece.
- the distal end of the accessory 2, and more precisely the plug 25, extends inside and in contact with the grip 24, longitudinally along the axis X-X '.
- the distal end of the accessory 2 protrudes inside the grip end 24 and the distal end and the grip end are in contact with each other on a certain length along the axis XX '.
- This allows the distal end to provide rotational guidance of the gripping endpiece relative to the accessory at a plurality of points along the axis X-X ’.
- the gripping tip extends, at least in part, along the axis X-X ’, around the distal end, and more precisely around the plug 25.
- the contact between the grip end 24 and the distal end of the accessory 2, or more particularly the plug 25, is a surface contact.
- the gripping end piece and the plug 25 are in contact on a continuous surface.
- Such a contact makes it possible to improve the guiding in rotation of the gripping endpiece relative to the accessory 2 in particular by distributing the radial forces well over the entire contact surface, which makes it possible to absorb said radial forces without compromising the rotation of the grip.
- the guide rib 254 of the plug 25 extends, longitudinally along the axis XX ′, inside and in contact with said cap 241 so as to define a contact surface cylindrical between the gripping end piece 24 and the accessory 2.
- the cylindrical contact surface has a length of between 2 mm and 15 mm, advantageously between 4 mm and 10 mm and is preferably equal to 6 mm.
- This length therefore corresponds to the contact length between the gripping end piece 24 and the plug 25, and therefore advantageously to the length of the guide rib 254, and has been optimized to guarantee good rotation guidance of the end piece grip 24 vis-à-vis the accessory 2 while containing the size of these elements.
- this length but above all the surface contact surface, and preferably cylindrical, makes it possible to remarkably contribute to good heat exchange between the plug 25 and the gripping end piece 24 which has an exchange surface with the fresh air. consequent environment (notably thanks to its cylindrical shape).
- the diameter of the cylindrical contact surface that is to say the diameter of the guide rib 254 or of the cap 241 can be between 10 mm and 50 mm, for example preferably being substantially equal to 27 mm.
- the gripping tip comprises a gripping relief 241 1, such as for example streaks, hollows, bumps or any other shape making it possible to prevent the fingers from l user slide on the grip 24.
- a gripping relief 241 such as for example streaks, hollows, bumps or any other shape making it possible to prevent the fingers from l user slide on the grip 24.
- the grip end 24 comprises a circular ring 2412 and integral with the grip tip 24 and preferably located at a proximal end of the grip tip.
- the gripping end piece comprises a circular rib projecting radially relative to the cap 241.
- This ring 2412 is designed to fit into the guide groove 253 defined above, that is to say under the guide flange 252.
- the ring 2412 disposed in the guide groove 253 thus achieves quite remarkable a stop in translation along the axis XX '.
- the ring 2412, the guide groove 253 and the guide flange 252 jointly produce an axial holding device to prevent any relative translation between the gripping end piece 24 and the distal end of the accessory 2
- the ring 2412 cannot translate within the guide groove 253, but it can rotate along the axis XX ′, which makes it possible, quite cleverly, to produce a second guide device in rotation of the gripping end piece 24 relative to the accessory 2. Thanks to this second rotary guide, distinct from the first rotary guide, the distribution of the axial forces is even better distributed which further improve the rotational guidance of the gripping end piece vis-à-vis the accessory.
- the diameter of the ring 2412, and therefore of the guide groove 253 is substantially equal to 34 mm.
- the gripping end piece 24 includes a hooking device 242 designed to interact with the main body 1 of the hairdressing accessory, and more precisely to allow assembly or disassembly (that is to say assembly or disassembly) of the accessory 2 on the main body 1 of the hairdressing appliance.
- the attachment device 242 is advantageously movable between an open position designed to allow the assembly or disassembly of the accessory 2 on a hairdressing device and a closed position designed to keep the accessory 2 assembled with the hair styling device.
- the closed position is a rest position, which makes it possible to guarantee permanently (except during disassembly phases of course) the proper attachment of the accessory 2 to the main body 1 of the hairdressing appliance.

More specifically, the elastic locking device 2422 can be inserted into a groove in the coupling device 195 so as to constitute a stop in translation along the axis X-X ’.
- the elastic locking device 2422 can be a spring whose shape is similar to that of the capital Greek letter Omega W.
- the hooking device 242 also comprises a chassis 2423 whose general shape is that of a capital U.
- the chassis 2423 makes it possible to hold in place the elastic locking device 2422 within the gripping end piece 24 by means of an axis (not shown) passing through a hole 2426 in the chassis 2423 and the elastic locking device 2422.
- the hole 2426 is located in the center of the non-parallel bar of the U, while the parallel bars of the U are in contact with the cap 241 in order to position the frame 2423 in the middle and inside of the cap 241.
- the hanging device 242 includes a locking button 2421 which allows, by acting directly on the elastic locking device 2422, to move the hooking device 242 between its open and closed positions.
- the attachment device 242 also includes a support 2425 of arcuate shape movable relative to the chassis 2423.
- a spring 2424 is disposed along each of the parallel bars of the U of the chassis 2423 between the chassis 2423 and the support 2425.
- the support 2425 is slidably mounted relative to the chassis 2423 by means of a sliding device 2427 comprising a groove produced in each of the parallel bars of the U of the chassis 2423 and two tongues integral with the support 2425.
- the support 2423 pushed back by the two springs 2424, makes it possible to hold the locking button 2421 in a position corresponding to the closed position, for example by being flush with the grip.
- the hooking device 242 forms a guide in rotation between the gripping end piece 24 and a device. hairstyle.
- Such an architecture also makes it possible to improve the distribution of the radial forces applied to the grasping tip by partially transferring them to the hairdressing device, which further improves the rotational guidance of the grasping tip.
