Title of the invention: HAIRDRESSING APPARATUS WITH ROTATING HEAD

The present invention relates to the general technical field of hairdressing devices, for example for domestic use, and more specifically to the field of portable electric hairdressing devices designed to blow an air flow in order to dry and / or facilitate hair shaping.

Hairdressing devices are known, of the hand-held hair dryer type, comprising a handle and a blowing head, which comprises an air outlet for directing a forced air flow, hot or cold, towards the hair. of a user. If such hair dryers are mainly used to dry damp hair, by evaporation of the water under the effect of the air flow blown by the hair dryer (drying function), they can however also be used in combination with a number of removable accessories designed to facilitate hair shaping (styling aid function). Intended to be fixed on the head of the hair dryer and to be traversed by the air flow emitted by the blowing head, these accessories - which can, for example, be of the diffuser or concentrator type - form nozzles modifying the shape of the air flow blown by the blowing head of the hair dryer.

These known hair dryers, if they are generally satisfactory, nevertheless have certain drawbacks. In particular, the passage of the hair dryer from a mode of use for drying to a mode of use for styling aid requires, on the part of the user, an operation of assembling / disassembling the accessories. . Such an operation can sometimes be tedious, and there is also a non-negligible risk of burns when handling the accessories, as well as loss of the accessories, when the latter are not simply stored out of reach and are inaccessible to the user when the user wishes to use them.

The objects assigned to the invention therefore aim to propose a new portable multifunctional hairdressing device which is particularly practical and simple to use.

Another object of the invention is to propose a new portable hair styling device of ergonomic design and particularly intuitive use.

Another object of the invention is to propose a new portable hair styling device of particularly simple and compact construction.

Another object of the invention is to propose a new portable hairstyling device which is particularly robust and reliable.

Another object of the invention is to propose a new portable hairstyling device which makes it possible to obtain particularly effective drying and shaping of the hair under comfortable conditions of use.

The objects assigned to the invention are achieved using a portable hairdressing apparatus comprising an onboard blower module for generating an air flow, and a manual gripping handle extended by a blowing head, said blowing head being provided with at least a first air outlet and a second air outlet, said first and second air outlets being separate and having openings of different geometries, said blowing head being mounted in rotation relative to the handle, between at least a first position in which said air flow is blown by the blowing head via said first air outlet and a second position in which said air flow is blown by the blowing head via said second air outlet.

Other features and advantages of the invention will appear and become more apparent on reading the description given below, with reference to the accompanying drawings, given solely by way of illustrative and non-limiting example, among which :

[Fig. 9] illustrates, in a side view, the hairdressing apparatus of FIG. 6.

[Fig.10] illustrates, in a side view in longitudinal section, the hair styling apparatus of Figures 6 to 9.

The 1.1 ’hair styling device according to the invention is designed to be grasped and manipulated by hand. It is therefore a portable, manual hairstyling device, preferably intended for use in a domestic setting by a user lacking particular professional skills in hairstyling, that is to say both in terms of drying. than styling, hair shaping.

Preferably, and in accordance with a first embodiment illustrated in Figures 1 to 5, the hair styling device 1 forms a hair dryer (or hair dryer), which allows a user to dry his wet hair or damp by blowing towards the hair with a forced air flow, hot or cold, and to facilitate shaping of the hair. The invention is however not limited to this specific embodiment and it is for example entirely conceivable that the hairdressing appliance 1 'forms a blower hair brush, in accordance with a second embodiment illustrated in FIGS. 6 to 10, or any other portable hairstyling device having a function involving the blowing of an air flow on the user's hair, and which could be more specifically used for styling purposes, for example in direct contact with hair (brushing, straightening, etc.).

For the sake of brevity, the following description will nonetheless be essentially centered on a hairdressing appliance 1 of the hair dryer type (FIGS. 1 to 5) and on a hairdressing appliance 1 ′ of the blower hairbrush type (FIGS. 6 to 10). Unless expressly stated otherwise, the technical characteristics described in connection with the hairstyling device according to the first embodiment advantageously remain transposable mutatis mutandis to a hairstyling device according to the second embodiment (and vice versa). Identical or analogous elements between the two embodiments illustrated in the figures will bear, in the description which follows, the same references.

The hair styling device 1.1 ′ according to the invention comprises a handle 2 (or handle) for manual gripping, intended to be grasped by Γ user to handle the hairdressing device 1, 1 ’. The handle 2 extends between a first end 3 and an opposite second end 4, preferably longitudinally along a first axis A-A ’. In the embodiments illustrated in the figures, the handle 2 is formed of a part - or an assembly of parts - generally tubular (for example of circular or elliptical mean section, constant or not), shaped and dimensioned to ensure it good handling by the user.

The hairdressing device 1,1 'also includes an on-board blower module 5, designed to generate an (forced) air flow, and a blowing head 6 which extends the handle 2 and through which the air flow generated by the blower module 5 is directed out of the hair styling device 1.1 ′, so that it can be projected towards the user's hair.

More specifically, the blowing head 6 is provided with at least a first air outlet 7 and a second air outlet 8, which are separate (and therefore different, not confused) one of the other. Advantageously forming a unitary sub-assembly, the blowing head 6 is rotatably mounted relative to the handle 2, between at least a first position in which the air flow generated by the blowing module 5 is blown by the blowing head 6 via the first air outlet 7, and a second position (FIGS. 5 and 10) in which said air flow is blown by the blowing head 6 via the second air outlet 8 of the latter. In other words, the blowing head 6 is mounted relative to the handle 2 in a pivot connection, so that it can thus rotate relative to the handle 2, and the hairdressing appliance 1, 1 ′ according to the invention is designed and configured to allow the user, by pivoting the blowing head 6 relative to the handle 2, to alternately select one or the other of the first 7 and second 8 air outlets of the blowing head 6 by which the air flow will be blown by the blowing head 6. Preferably, the blowing head 6 is designed to remain permanently attached to the handle 2 of the hairdressing appliance 1, 1 ', the blowing head 6 n' being not intended (in normal use) to be dissociated from the handle 2 of the hair styling device 1.1 ′ by the user.

According to the invention, the first 7 and second 8 air outlets have openings of different geometries. In other words, the useful air passage section of the opening of the first air outlet 7 is defined by a contour (or a plurality of contours) of shape different from the shape of the contour (or the plurality of contours) which respectively defines the useful air passage section of the opening of the second air outlet 8. The flow of air blown by the blowing head 6 will therefore thus affect a different profile depending on the outlet d 'air 7, 8 selected, so that the user can make use of the hair styling device 1.1' according to at least two different blowing configurations. Thus, the first air outlet 7 and second air outlet 8 are advantageously designed to blow, project, two air streams of different profiles, respectively a first air stream and a second air stream, each of the latter allowing the user to perform a different operation on his hair. For example, the first air flow may correspond to a drying air flow, of broad and diffuse profile, and of high flow rate (for example, of the order of 70 m ³ / h), to allow the user to quickly dry their hair. The second air flow can correspond to a shaping air flow, of concentrated and narrow profile, and of lower flow rate (for example, of the order of 50 m ³ / h), to allow the user to choose precisely the location of his hair to which the second air flow will be blown. In this way, the user can skillfully and easily achieve shaping of his hair, such as for example waves, or on the contrary smoothing.

For example, in the first embodiment illustrated in Figures 1 to 5, where the hair styling device 1 forms a hair dryer, the first air outlet 7 has an opening of generally circular shape substantially circular (Figure 2 ), while the second air outlet 8 (Figures 1 and 3) has a generally oblong, elongated opening. Thus, when the blowing head 6 occupies said first position relative to the handle 2, the hairdressing apparatus 1 can be used in a conventional manner for drying wet hair, the first flow of air blown by the blowing head 6 having, in the vicinity of the first air outlet 7, a substantially cylindrical or conical profile. When the blowing head 6 occupies said second position relative to the handle 2, the hairdressing device 1 can then be used to dry the hair while facilitating the shaping of the hair (for example, to carry out “brushing”), the second flow of air blown by the blowing head 6 forming, in the vicinity of the second air outlet 8, an air space which allows the user to choose with precision the place of his hair where to apply the flow of air to achieve shaping.

By way of illustration and not limitation, the opening of the first air outlet 7, which is preferably intended to produce a first flow of drying air, may have a first useful section of air passage whose l the area is advantageously between 707 mm ² and 1,963 mm ² , and for example equal to 962 mm ² (which corresponds, for an opening of the first air outlet 7 of circular shape, to a diameter preferably between 30 and 50 mm, and preferably equal to 35 mm). The opening of the second air outlet 8 may advantageously have a second useful air passage section, the area of which is less than that of said first useful air passage section of the opening of the first air outlet 7. For example, making said second useful air passage section can be between 240 mm ² and 640 mm ² , and for example be equal to 360 mm ² (which corresponds, for an opening of second air outlet 8 of oblong shape, at a length of about 60 to 80 mm and a width of about 4 to 8 mm, and preferably at a length of about 60 mm for a width of about 6 mm ).

In the second embodiment illustrated in Figures 6 to 10, where the hair styling device 1 'forms a blower brush, the first air outlet 7 has for example an opening of generally substantially oblong shape, elongated (Figure 7), while the second air outlet 8 (Figures 6 and 8) has for its part, for example, an opening consisting of a multitude of orifices distributed between rows of brush bristles (or pins), each of these orifices being of generally circular shape. Thus, when the blowing head 6 occupies said first position relative to the handle 2, the hairdressing apparatus 1 ′ can be used, for example, to carry out a pre-drying of the hair by blowing a first air flow of broad profile. and diffuse, and high throughput. When the blowing head 6 occupies said second position relative to the handle 2, the hairdressing apparatus 1 ′ can then be used, for example, to brush the hair while finalizing the drying of the latter, by blowing a second flow. more concentrated profile air but less flow, closer to the hair brushed by the bristles (or pins) of brush.

Thus, the hairstyling device 1.1 ′ according to the invention advantageously allows the user to choose between at least a first mode of use (for example for drying) and a second mode of use (by example of hair shaping) of the hairdressing apparatus 1,1, 'by a simple rotation of the blowing head 6 relative to the handle 2, which rotation makes it possible to select, in a particularly simple and rapid manner, a profile of air flow adapted to the operation to be performed on the hair.

It is conceivable, without departing from the scope of the invention, that the first and second air outlets are one and / or the other formed by accessory parts removably assembled (for example by snap-on, screwing, press fitting, etc.) to the rest of the blowing head rotatably mounted relative to the handle (variant not shown). Indeed, this would allow the user to equip the hairdressing device 1, 1 'with two air outlets (and not just one, as is the case for conventional drying appliances), distinct and sections of different geometries, and to be able to use successively one or the other of them, without intermediate operations of disassembly / reassembly of parts, while nevertheless retaining the option of exchanging one or the other of these accessory parts according to the particular use that the user wishes to make of the hairdressing appliance.

It is however advantageous that the blowing head 6 on the contrary forms a coherent assembly, not intended to be disassembled by the user, the first 7 and second 8 air outlets being formed by one or more irremovable components (in normal use) belonging to the blowing head 6. Thus, by means of a rotation of the blowing head 6 relative to the handle 2 of the device 1.1 ′, the user can, in a completely remarkable, select one or the other of the first air outlet 7 or second air outlet 8, and therefore advantageously choose the air flow profile he wishes, without having to install or dismantle any element 1.1 'hair styling accessory. The user thus benefits from easy and rapid use of the device 1, 1 'and is sure not to lose any element of the latter.

More specifically, the blowing head 6 is rotatably mounted relative to the handle 2 around a second axis B-B 'which is preferably coincident with the first axis A-A' of extension of the handle 2, as in the embodiments illustrated in the figures. However, the second axis B-B ’of rotation could be parallel to said first axis A-A’ (and more or less offset from the latter). The kinematics of the blowing head 6 is thus simple and reliable, and allows an intuitive handling of the hairdressing apparatus 1 by the user. Alternatively still, it could be envisaged that the second axis B-B ’is intersecting said first axis A-A’ at an angle typically between 5 and 15 °.

To allow easy use of the hair styling device 1, 1 'in all circumstances, in particular for treatment of the hair from the back of the user's head, the first 7 and second 8 outlets air are preferably arranged and configured so that the air flow generated by the blower module 5 is blown by the blowing head 6 in a mean secant direction, and preferably substantially orthogonal, to the first axis A-A 'd' longitudinal extension of the handle 2. In a particularly advantageous manner, the hairdressing appliance 1 1 ′ can be designed and configured so that the blowing head 6 blows the air flow in a substantially identical mean direction and direction whatever the first position or the second position occupied by the blowing head 6 relative to the handle 2. Thus, the user can alternatively use the hair styling device 1.1 ′ in one then in the other of said first and second po blower head 6, without having to modify its manual grip on the handle 2 or to modify the general spatial orientation of the 1.1 ’hair styling device.

As illustrated as an example in the figures, the passage of the blowing head 6 from said first position to said second position preferably corresponds to a rotation of said blowing head 6 by an angle of 180 ° around said second axis BB ' . In other words, the blowing head 6 of the hairdressing appliance 1, 1 ′ is designed and configured in such a way that the first 7 and second 8 air outlets of the blowing head 6 are arranged on either side of the second axis B-B 'of rotation of the blowing head 6 relative to the handle 2. This arrangement contributes to a practical and particularly intuitive handling of the hairdressing apparatus 1,1' by the user.

Preferably, the first and second positions of the blowing head 6 are stable positions, so that the blowing head 6 can not leave the position it occupies unexpectedly, without voluntary action on the part of the user. As such, the hairdressing device 1,1 ′ advantageously comprises means of indexing (not illustrated) of the blowing head 6 in said first and second positions relative to the handle 2, such as for example pairs of magnets, "goose bumps" or any other known and suitable means.

This being stated, it is understood that the invention is however not limited to the implementation of a blowing head 6 comprising only two air outlets 7, 8, in particular oriented at 180 ° l 'from each other relative to the second axis B-B' of rotation of the blowing head relative to the handle 2, although this assumption is retained in the preferred embodiments illustrated in the figures. Indeed, the blowing head 6 could quite comprise a greater number of distinct air outlets and sections of different geometries (for example, 3 or 4), which could be selected by par user by rotation of the blowing head relative to the handle and positioning of the blowing head in as many corresponding distinct positions.

These three or four (or more) air outlets would then preferably be regularly distributed around the second axis B-B ’of rotation, according to equal angular sectors as a function of the number of said air outlets. For example, one could thus envisage the implementation of three separate air outlets and having openings of different geometries, arranged in relation to each other so that the passage of the blowing head from a first position towards a second position, then from this second position towards a third position, corresponds for example to a rotation of the blowing head by an angle of 120 ° around said second axis BB '. One could also consider, for example, the implementation of four separate air outlets and having openings of different geometries, arranged relative to each other so that the passage of the blowing head from a position given to another corresponds, for example, to a rotation of said blowing head by an angle of 90 ° around said second axis B-B '. In addition, the rotation of the blowing head around the second axis B-B ', to move the blowing head from a given position to another, could obviously correspond to a different angle of rotation of the ratio of 360 ° on the total number of separate air positions / outlets.

The blower module 5 of the hairdressing device 1.1 ′ preferably comprises a motor-fan group 10, itself comprising an electric motor 11. The motor-fan group 10 can comprise a conventional axial fan with propeller or helical. Alternatively, the motor-fan unit 10 can advantageously comprise a fan of the helico-centrifugal or centrifugal type. The use of such a helical-centrifugal or centrifugal fan can make it possible to obtain, with equivalent dimensions, a high internal pressure with an air flow rate substantially similar to that of a propeller or helical fan, but with a lower rotation speed and therefore less noise generated by the motor-fan unit 10. Preferably, the electric motor 11 of the motor-fan unit 10 is a brushless electric motor (so-called “brushless” motor or synchronous self-piloting machine with permanent magnets). Such a brushless motor is generally more robust and lighter than a conventional brushed electric motor. Less noisy and more energy efficient, it also offers greater flexibility and better precision in adjusting its rotation speed.

The blower module 5 can be arranged within the handle 2 or within the blowing head 6. More preferably, however, the blower module 5 of the hairdressing appliance 1 is assembled to the handle 2 at level of the first end 3 of the latter, the blowing head 6 being in turn mounted in rotation relative to the handle 2 at the second end 4 of the latter, as in the embodiments illustrated in the figures. The blowing head 6 thus extends from the second end 4 of the handle 2, while the blower module 5 extends the handle 2 from the first end 3 of the latter. Preferably, the blower module 5 is secured to the handle 2, at the first end 3 of the latter, without the possibility of rotation of the blower module 5 relative to the handle 2. In addition, said blower module 5 can itself even to be extended by a power supply cord 9, as for example illustrated in FIGS. 6 to 10. The blower module 5 of the hairdressing apparatus 1, 1 ′ is therefore preferably offset from the blowing head 6 and of the handle 2 for gripping the hairdressing appliance 1, 1 '. It is thus possible to size the blower module 5 so as to generate an air flow with a large flow, economically, and without impacting the overall size of the blowing head 6 and of the handle 2. In addition, such an arrangement of the blower module 5 advantageously makes it possible to better balance the weight of the hairdressing apparatus 1, by a distribution of the masses on either side of the handle 2, which contributes to the comfort of use of this last.

In the case where the blower module 5 is arranged within the handle 2 or is assembled to the handle 2 at the first end 3 of the latter, the handle 2 may advantageously include a guide channel 12 of the flow d air generated by the blower module 5 towards the blowing head 6. Said guide channel 12 advantageously channels said air flow through the handle 2, typically in the direction of the first end 3 of the handle 2 towards the second end 4 of the latter. The hairstyling device 1,1 'can also advantageously comprise a deflector 13, designed and configured to guide the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 towards the first outlet of air 7 when the blowing head 6 occupies said first position, and vice versa towards the second air outlet 8 when the blowing head 6 occupies said second position.

In the first embodiment of Figures 1 to 5, the motor fan group 10 advantageously comprises a fan 14 of the centrifugal type, and the blower module 5 comprises an internal working chamber 15 in the form of a scroll, within of which the motor-fan unit 10 is housed. Said working chamber 15 can, as illustrated in FIG. 5, be defined by the internal walls of two half-hulls 16, 17 assembled together (for example, by screwing) and secured to the handle 2 at the first end 3 of the latter. The blower module 5 is provided with an air inlet 18, by which the ambient air is sucked axially by the fan 14 within the working chamber 15, and an air outlet which is advantageously connected to the channel 12 for guiding the air in the handle 2 and through which the sucked air is discharged radially out of the working chamber 15. The blower module 5 also preferably comprises a grid (possibly removable and repositionable) for protecting the inlet of air 18 from the working chamber 15. As illustrated in particular in FIG. 5, the blower module 5 is preferably designed and configured so that the axis of the centrifugal fan 14 of the fan unit 10 is substantially orthogonal to the first axis A-A 'of longitudinal extension of the handle 2. The air inlet 18 of the working chamber 5 is preferably arranged so that the ambient air is sucked into the working chamber 15 in a substantially parallel direction els to the mean direction of blowing of the air flow through the blowing head 6 and, even more preferably, in an identical direction. One could however envisage, without departing from the scope of the invention, that the ambient air be sucked into the working chamber 15 in a secant direction, and for example substantially orthogonal, to the mean direction of blowing of the flow of air through the blower head 6.

As regards the second embodiment illustrated in FIGS. 6 to 10, in which the hairdressing appliance 1 forms a blower hair brush, the fan unit 10 preferably comprises a fan 14 of the helical type. Attached to the handle 2 at the first end 3 of the latter, the blower module 5 comprises an internal working chamber 15 which is substantially cylindrical, within which is housed the motor-fan group 10. The motor-fan group 10 is mounted so that the axis of the helical fan 14 is parallel, and preferably coincident, with the first axis A-A 'of longitudinal extension of the handle 2. The blower module 5 is provided with an inlet air 18, for example screen, by which the ambient air is sucked in radially by the fan 14 within the working chamber 15, and an air outlet which is advantageously connected to the air guide channel 12 of the handle 2 and by which the sucked air is discharged axially out of the working chamber 15. Such an arrangement advantageously makes it possible to limit the radial size of the part of the hairdressing apparatus 1 ′ formed by the handle 2 and the blower module 5.

Preferably, the blowing head 6 comprises an outer casing 20 which defines the shape and the outer contour of the blowing head 6 and, advantageously, the shape and the outer contour of a terminal part of the apparatus. 1,1 'hairstyle which extends the handle 2 of said 1,1' hairstyling appliance. Advantageously, the external envelope 20 is shaped to allow manual gripping by the user, so that the latter can print directly by hand to said external envelope 20 (and therefore to the blowing head 6), a pivoting movement. around the second axis B-B 'of rotation of the blowing head 6 relative to the handle 2, to select one or the other of said first 7 and second 8 air outlets of the blowing head, and therefore the corresponding operating mode of the hair styling device 1,1 '.

Advantageously, the blowing head 6 comprises a nozzle body 19 for guiding the air flow out of the hairdressing appliance 1, in the direction of the user's hair. In the first embodiment illustrated in Figures 1 to 5, the nozzle body 19 is advantageously embedded in said outer casing 20 (or fairing), formed for example of half-shells assembled by snap-fastening or by screwing. The rotation, by the user, of the outer casing 20 of the blowing head 6 around the second axis B-B 'causes the joint body of the nozzle 19 to rotate around said second axis B-B'. The outer casing 20 can be shaped to give the blowing head 6 a particular aesthetic appearance, for example a generally cylindrical appearance as illustrated in examples in Figures 1 to 5.

Advantageously, the outer casing 20 of the blowing head 6 extends generally longitudinally along a third axis C-C 'orthogonal to a median plane of the blowing head 6, said blowing head 6 being arranged relative to the sleeve 2 so that the second axis B-B 'of rotation of the blowing head 6 is coincident with the first axis A-A' of longitudinal extension of the handle 2, and that said first A-A 'and second B- B 'axes are inscribed in the median plane of the blowing head 6. The outer casing 20 therefore advantageously extends along a third axis C-C' which is orthogonal to both the first axis A-A 'of extension longitudinal of the sleeve 2 and to the second axis B-B 'of rotation of the blowing head 6, and over an average length substantially equal on either side of said first A-A' and second B-B 'axes.

In addition to the aesthetic effect of symmetry or quasi-symmetry which can be thus obtained, this particular arrangement advantageously contributes to a good general balance and to good maneuverability of the hairdressing apparatus 1 by the user.

As illustrated in particular in the sectional view of Figure 5, the nozzle body 19, advantageously monolithic, preferably extends itself along the third axis C-C 'of longitudinal extension of the blowing head 6 between, on the one hand, a first end of the nozzle forming the first air outlet 7 of the blowing head 6 (which advantageously has an opening of generally circular shape, as mentioned above) and, on the other hand part, a second opposite nozzle end forming, for its part, the second air outlet 8 of the blowing head 6 (which advantageously has a generally oblong opening, elongated, in a direction perpendicular to the second axis B- B 'of the blowing head 6).

In this first particular embodiment, the hair styling device 1 also includes a deflector 13, as envisaged above, for guiding the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately towards one or the other of said first 7 and second 8 air outlets, according to the position occupied by the blowing head 6. As illustrated in FIG. 5, the deflector 13 preferably comprises a bent tubular element 21, mounted fixed relative to the handle 3 and extending the air guide channel 12 of said handle 2 along the first axis A-A 'of extension of the handle 2. Thus, the blowing head 6 advantageously rotates around the bent tubular element 21 of the deflector 13, when it passes from one to the other of said first and second positions.

Particularly preferably, the bent tubular element 21 forms with the handle 2 a monolithic part (Figure 5), which in particular allows to limit the number of parts of the hairdressing apparatus 1, and therefore in facilitate manufacturing.

As illustrated in Figure 5, the nozzle body 19 advantageously comprises an air inlet orifice 22, of dimensions combined with those of the bent tubular element 21 of the deflector, and through which said element bent tubular 21 enters the nozzle body 19, along the second axis B-B 'of rotation of the blowing head 6. The bent tubular element 21 and the nozzle body 19 are advantageously configured and arranged one with respect to to the other so that, when the blowing head 6 occupies said first position, the bent tubular element 21 directs the air flow in the nozzle body 19 towards the first nozzle end forming the first outlet d 'air 7 from the blowing head 6, while preferably preventing any air leakage towards the second opposite nozzle end. Conversely, the bent tubular element 21 and the nozzle body 19 are advantageously configured and arranged relative to each other so that, when the blowing head 6 occupies said second position (in this case, at the following a rotation of the blowing head 6 by an angle of 180 ° around the second axis B-B '), the bent tubular element 21 then directs the air flow in the nozzle body 19 in the direction of the second nozzle end forming the second air outlet 8 of the blowing head 6, while preferably preventing any air leakage in the direction of the opposite first nozzle end (FIG. 5). As illustrated, the deflector 13 (and in particular the bent tubular element 21 of the latter) and the nozzle body 19 are advantageously shaped and arranged to subject the air flow coming from the air guide channel 12 of the handle 2 a 90 ° deflection towards one or the other of the first 7 and second 8 air outlets.

A different design of the blowing head 6 of the hairdressing apparatus 1 can obviously be envisaged, such as, for example, that illustrated in Figures 6 to 10 in connection with the second preferred embodiment of the hairdressing appliance 1, 1 'according to the invention.

The hair styling apparatus 1 ’illustrated in FIGS. 7 to 10 forming a blowing hair brush, the blowing head 6 here advantageously has an external shape substantially similar to that of a conventional hair brush. As such, the blowing head 6 thus extends longitudinally along a fourth axis D-D 'parallel to, and preferably coincident with, the second axis B-B' of rotation of the head relative to the handle 2. As illustrated, the blowing head 6 is also arranged relative to the handle 2 so that the second axis B-B 'of rotation of the blowing head 6 is coincident with the first axis A-A' of longitudinal extension of the handle 2 .

As illustrated in particular in Figure 10, the blowing head 6 may include a nozzle body 19, which this time is not in the form of a separate part mounted in the outer casing 20 of the head blowing 6, but which is on the contrary directly defined by an inner wall of said outer casing 20. Said outer casing 20 may, similarly to the first embodiment, be formed of a plurality of shell elements assembled together (for example, by snap-fastening or screwing). Said nozzle body 19 then advantageously extends along a fifth axis E-E 'orthogonal to the fourth axis D-D' of longitudinal extension of the blowing head 6, between, on the one hand, a first nozzle end forming the first air outlet 7 from the blowing head 6 and, on the other hand, a second opposite nozzle end forming, for its part, the second air outlet 8 from the blowing head 6.

The first air outlet 7 of the blowing head 6 advantageously has an opening of generally substantially oblong shape, elongated, in a general direction parallel to the fourth axis D-D 'of longitudinal extension of the blowing head 6 (Figure 7). The second air outlet 8 has, for example, an opening consisting of a multitude of orifices distributed between rows of bristles (or pins) of brush which is advantageously provided with the blowing head 6, each of these orifices being of generally circular shape (Figures 6 and 8).

In this second particular embodiment, the hair styling device 1 'also includes a deflector 13 for guiding the air flow generated by the blower module 5 from the guide channel 12 of the handle 2 alternately towards the one or the other of said first 7 and second 8 air outlet, depending on the position occupied by the blowing head 6. As illustrated in FIG. 15, the deflector 13 preferably comprises a bent tubular element 21, in this case formed of a section of frustoconical tube closed at one end and the side wall of which is provided with an axial opening. Fixed relative to the handle 2, the bent tubular element 21, extends the air guide channel 12 of said handle 2 beyond the second end 3 and along the first axis A-A ’of extension of the latter.

As illustrated in Figure 5, the nozzle body 19 advantageously comprises an air inlet orifice, of dimensions combined with those of the bent tubular element 21 of the deflector 13, and through which said element bent tubular 21 enters the nozzle body 19, along the second axis B-B 'of rotation of the blowing head 6. The respective configurations and arrangements of the bent tubular elements 21 and nozzle body 19 of the hairdressing apparatus 1 'according to the second embodiment of Figures 6 to 10 are advantageously similar, if not identical, to those described above in connection with the bent tubular element 21 and nozzle body 19 corresponding to the hairdressing apparatus 1 according to the first mode of Figures 1 to 5, and produce substantially the same effects.

Advantageously, one and / or the other of the first 7 and second 8 air outlets from the blowing head may (have) also be provided with one or more deflector flaps, more or less inclined and preferably fixed, designed and configured to homogenize, if necessary, the spatial speed / flow profile of the air flow blown through the air outlet concerned. For example, in the embodiments illustrated in the figures, the first air outlet 7, the geometry of the opening of which is advantageously adapted to use of the hairstyling device 1.1 ′ for drying / pre-drying purposes hair drying, is provided with such deflector flaps 23. In the first embodiment of Figures 1 to 5, the deflector flaps 23 advantageously come in one piece with the nozzle body 19. Alternatively, the deflector flaps 23 can be formed by a separate added part, as in the second embodiment of FIGS. 6 to 10. The second air outlet 8, the geometry of the opening of which is preferentially suitable for use of the hairdressing appliance 1, 1 'for purposes of styling aid or styling of the hair, is itself devoid of deflector flaps.

Preferably, the hairdressing device 1,1 'comprises a heating element 24 designed to raise the temperature of the air flow generated by the blower module 5. Embedded within the hairdressing device 1,1 ', the heating element 24 can be arranged within the blowing head 6 or within (that is to say inside) of the handle 2 of the latter. Advantageously, the heating element 24 is arranged (at least in part) within (that is to say inside) of the handle 2, and even more advantageously even inside the channel of guide 12 of said sleeve 2, as in the embodiments illustrated in the figures, so as to be interposed in the air flow generated by the blower module 5. Such a configuration makes it possible in particular to reduce the size and the weight of the blowing head 6, and to simplify the design thereof. It is typically an electric heating element, operating on the principle of the Joule effect, and the power of which is preferably greater than 500 W. Preferably, the heating element 24 comprises at least one electric heating resistance formed by winding a metallic conducting wire (for example, in nichrome) around an insulating core. In the preferred embodiments illustrated in the figures, the heating element 24 is more precisely in the form of a winding of a metallic conductive wire (not illustrated) around an insulating core 25 (for example, made of mica) cross-shaped and provided at its ends with fixing fins. Advantageously, the hairdressing device 1,1 ′ further comprises a thermal insulator 26, for example a tubular piece 26 with a circular base, within which the heating element 24 is mounted, and which in particular makes it possible to protect the user from risk of burns by limiting heating of the handle 2. As illustrated in the figures, the inner wall of the thermal insulator 26 can advantageously define all or part of the guide channel 12 of the air flow mentioned above.

Preferably, the hairstyling device 1,1 'also includes an electronic module 27. Not necessarily intended to be manipulated directly by the user, nor even to be accessible by the latter, the electronic module 27 is advantageously designed to interact (directly or indirectly) with all or part of the different functional organs that the hairdressing apparatus can include 1. It is typically a card, an electronic circuit, a printed circuit ("PCB") ) or a set of electrical, electronic or electromechanical components, internal to the hairdressing appliance 1, 1 '. The electronic module 27 may be intended to provide a particular mode of electrical supply (with, for example, a filtering, transforming or rectifying current function), to provide monitoring, control or even regulation of the operation of one and / or the other of the functional organs of the hairdressing apparatus 1,1 '. Optionally, said electronic module 27 can comprise components such as an electric battery, a display, one or more microcontroller (s), etc. The electronic module 27 can optionally be connected to a certain number of sensors and sensors distributed in the hairdressing apparatus 1, 1 ′ and intended to measure, to monitor, physical quantities linked to the functioning of the latter (temperatures, voltages and intensities electrical, air flow speeds / flow rates, rotation speed of the fan 14 of the blower module 5, etc.), in order to optimally control the operation of the various functional organs of the hairdressing appliance 1 , 1 '.

More preferably, said electronic module 27 is an electronic module designed to control the operation of the blower module 5 and / or the heating element 24 of the hairdressing appliance 1, 1 ’. Indeed, the blower module 5 and / or the heating element 24 of the hairdressing appliance 1, 1 ′ may require, for their respective operation and according to the technologies employed, the implementation of one (or more) specific control module (s) or electronic card (s).

For example, when the electronic module 27 is designed to control the operation of the heating element 24, the electronic module 27 may include a circuit for controlling electrical power and / or specific regulation (power, temperature, etc. .) of said heating element 24. In the preferred case where the blower module 2 comprises a brushless electric motor 11, as envisaged above, the control of said brushless electric motor 11 can be advantageously ensured by the electronic module 27. A As such, the electronic module 27 can then be designed to ensure in particular the switching of the electric current in the stator windings (phase control) of the motor 11 as a function of data from position sensors (for example, Hall effect), Γ self-regulation of rotation speed, etc.

Preferably, as in the first preferred embodiment illustrated in Figures 1 to 5, such an electronic module 27 is advantageously arranged within the blowing head 6, preferably outside the air flow circulating within the latter. Advantageously, the blowing head 6 comprises a dedicated compartment 28, capable of receiving said electronic module 27.

Such an arrangement helps to limit the overall size of the hairdressing device 1, 1 ', in particular in the case where the electronic module 27 is designed to control the operation of the blower module 5 and / or the heating element 24 and that the latter are arranged outside the blowing head 6. Thus, when as mentioned above the heating element 24 is arranged within the handle 2 and / or the blowing module 5 is assembled within of the handle 2 or at one end of the latter, the electronic module 27 is then advantageously offset from the heating element 24 and / or from the blower module 5 which it controls, which makes it possible to limit the overall dimensions of the handle as much as possible. 2 and / or the blower module 5 connected to the latter.

However, given the rotary nature of the blowing head 6, it can then be difficult to ensure a simple and robust electrical connection between, on the one hand, the heating element 24 and / or the module blower 5 arranged outside the blowing head 6 (or any other functional member of the hairdressing apparatus 1,1 'which would be connected to the electronic module 27 and which would be arranged outside the blowing head 6) and, on the other hand, the electronic module 27 arranged in the blowing head 6.

This is why, as in the first preferred embodiment illustrated in Figures 1 to 5, the electronic module 27 is preferably mounted, within the blowing head 6, so as to remain stationary relative to the blower module 5 and / or to the heating element 24 during the rotation of the blowing head 6. As such, and as illustrated in example in FIG. 5, the nozzle body 19 may be provided with an additional orifice 29, which is opposite to the air inlet orifice through which the bent tubular element 21 of the deflector 13 enters the nozzle body 19. At the level of said additional orifice 29 is flush with or protrudes outside of the nozzle body 19 a portion of the bent tubular element 21 to which the electronic module 27 can be fixed, directly or through a specific support 30. Obviously, other suitable mounting configurations can be envisaged. For example, depending on its size, the electronic module 27 could be mounted on the back of the bent tubular element 21 of the deflector 13.

In this way, the electrical connection between the heating element 24 and / or the blower module 5 and the electronic module 27 arranged in the blowing head 6 can advantageously be carried out very simply, using for example conventional electrical conductor wires (not shown), without risk of damaging the electrical wires by torsion or even without requiring the use of complex mobile electrical connection means (of the rotary connector connection type, for example). The manufacturing cost of the hairdressing appliance 1 is thus limited and its reliability increased.

Being housed within the blowing head 6, and although preferably arranged outside the air flow flowing through the latter, the electronic module 27 is likely to see its temperature increase significantly when the air flow generated by the blower module 5 is heated by the heating element 24 before being blown out of the device 1 by the blowing head 6. In addition, and even so the heating element 24 is not activated or the hairdressing appliance does not include such a heating element, the electronic module 27 is liable, during its normal operation, to heat up by itself under the effect in particular of the electric current which passes through it. In all cases, this results in a high risk of malfunction, or even total failure, of the electronic module 27, if the temperature of the latter is not controlled and comes to exceed a certain tolerance threshold.

In a particularly advantageous manner, the hairdressing device 1.1 ′ may as such comprise a bypass channel 31 designed to capture part of the air flow generated by the blower module 5 in order to ensure cooling. of the electronic module 27. The bypass channel 31 is thus designed and configured to ensure the collection and diversion of part of the forced air flow produced by the blower module 5 - before said air flow is, if necessary, heated by the heating element 24 - in order to guide and blow the part of the air flow thus taken as close as possible to the electronic module 27 to ensure forced cooling of the latter.

In the case where the blower module 5 is arranged within the handle 2 or is assembled to the handle 2 at the first end 3 of the latter, said bypass channel 31 preferably extends at least in part in the handle 2. The bypass channel 31 is thus advantageously integrated into the handle 2. Even more preferably, the hair styling device 1,1 ′ can be designed so that the guide channel 12 and the bypass channel 31 extend parallel to each other within the handle 2, advantageously along the first axis A-A 'of extension of the latter.

For example, in the first preferred embodiment illustrated in Figures 1 to 5, the bypass channel 31 opens, on the one hand, at the air outlet of the working chamber 15 of the blower module 5, to capture part of the air flow there (fresh, that is to say not yet heated by the heating element 24) generated by said blower module 5 and, on the other hand, in the immediate vicinity of the electronic module 27 which is arranged in the blowing head 6.

As illustrated as an example in Figure 5, said bypass channel 31 can be formed, along all or part of the length of the handle 2, by a free space formed between an inner wall of the handle 2 and an outer wall of the 'tubular thermal insulator 26. Such a design also advantageously makes it possible to cool the handle 2, which improves the comfort of use of the 1.1 ’hairdressing appliance. Said bypass channel 31 can advantageously extend, at the level of the blowing head 6, inside a double-walled wall 32 forming a back of the bent tubular element 21, then through the support 30, mentioned above, by means of which the electronic module 27 is fixed to the bent tubular element 21.

Advantageously, the hairstyling device 1, 1 ′ may also comprise a circuit for re-injecting the part of the air flow captured in the air flow (main) blown by the blowing head 6, so that after having contributed to the cooling of the electronic module 27, the part of the air flow which has been captured by the bypass channel 31 can itself be blown towards the hair of the user by means of the air outlet (s) 7, 8 of the blowing head 6. In this way, the cooling of the electronic module 27 does not substantially affect the flow rate of the air flow generated by the blower module 5 and blown by the blowing head 6. For example, the nozzle body 19 of the blowing head 6 may be provided with an orifice (not shown) for reinjection of the air flow part captured directly inside the nozzle body 19, preferably downstream of the bent tubular element 21 of the deflector 13.

Alternatively (or additionally), the outer casing 20 of the blowing head 6 can be provided with gills (or equivalent) by which all or part of the captured air flow part can escape out of the blowing head 6, and therefore out of the hairdressing apparatus 1,1 '. Thus, the part of the air flow used to cool the electronic module 27 can be discharged to the outside of the hairdressing appliance 1, 1 ′ without impacting (or at least without significantly impacting) the temperature. of the (main) air flow blown by the blowing head 6 towards the hair of the user.

Typically, said bypass channel 31 can be dimensioned to allow the passage within it of an air flow of between 1 and 10 m ³ / h, to allow efficient cooling of the electronic module 27.

According to a variant, used in the embodiments illustrated in the figures, the hairstyling device 1,1 'comprises manual means 33 for adjustment, by the user, of the operation of the blower module 5 and / or the heating element 24. These are adjustment means, for example of the rocker switch, push button type and / or of the slide or wheel dimmer type, on which the user can directly act in order to electrically activate / deactivate the hairdressing appliance 1, 1 ′ and modify the speed of rotation of the fan 14 of the blower module 5, and therefore the speed / flow rate of the air flow blown by the blowing head 6, and / or the heating temperature of the heating element 24. Such manual adjustment means, known as such, can be positioned, for example, at the level of the handle 2 or at the level of the blower module 5, when the latter is assembled at the first end 3 of the latter as illustrated in x figures.

According to another variant (not illustrated), the hairstyling device 1, 1 ′ may include automatic means for adjusting the operation of the blower module 5 and / or the heating element 24, which automatic means for adjusting (automatically) control the operation of the blower module 5 and / or the heating element 24 in the position occupied by the blowing head 6 relative to the handle 2. In other words, these are then adjustment means on which the user acts not directly, but indirectly by means of the rotation of the blowing head 6 relative to the handle 2. Said automatic adjustment means thus cooperate with the blowing module 5 and the heating element 24 (if necessary, via the electronic module 27 mentioned above) in order to automatically modify the respective operation in response to a modification, operated by the user, of the position of the blower head age 6 compared to round 2.

Such automatic adjustment means can be formed by any means otherwise known as such and adapted to such an automatic servo-control function. For example, said automatic adjustment means may include in particular one or more switches or contactors (electrical, optical, mechanical or even magnetic), and / or one or more potentiometers, and / or one or more or position sensors of the head. blowing 6 relative to the handle 2. Typically arranged at the interface between the blowing head 6 and the handle 2, and electrically connected to the blowing module 5 and / or to the heating element 24 (if necessary, by the intermediary of the electronic module 27 mentioned above), such automatic adjustment means are capable of being activated or deactivated depending on the position occupied by the blowing head 6 relative to the handle 2, in order to modify the operation of the module in return. blower 5 and the heating element 24. In this way, it is advantageously possible to provide that each of said first and second positions of the blowing head 6 corresponds to a different predefined setting rent from the operation of the blower module 5 and / or the heating element 26, and preferably to a predefined setting different from the operation of both the blower module 5 and the heating element 24.

Said automatic adjustment means could preferably be designed and configured so that at said first position of the blowing head 6 correspond a first speed F1 and a first temperature Tl of the air flow blown by the blowing head 6 ( therefore via the first air outlet 7 of the latter). Conversely, said automatic adjustment means could preferably be designed and configured so that at said second position of the blowing head 6 correspond a second speed F2 and a second temperature T2 of the air flow blown by the blowing head 6 (by the intermediary therefore, this time, the second air outlet 8 of the latter).

Even more preferably, said first F1 and second F2 speeds of the flow of air blown by the blowing head 6 may be different from each other, and said first T1 and second T2 temperatures of the flow d air blown by the blowing head 6 may be different from each other. However, it nevertheless remains conceivable that said automatic adjustment means can be designed and configured to cooperate with the blower module 5 and the heating element 24 in order to automatically maintain an identical speed or temperature of the supply air flow whatever the position of the blowing head 6, and therefore whatever the air outlet 7, 8 selected and the geometry of the opening thereof.

Thus, each of said first and second positions of the blowing head 6 can automatically be associated with a speed-temperature couple of the blown air flow which can be advantageously predefined and optimized for a particular use of the hairdressing appliance. 1.1 '. Said first speed F1 and first temperature T1 of the air flow blown by the blowing head 6 can be advantageously predefined and optimized for use of the hairdressing apparatus 1 for hair drying purposes. Said first position of the blowing head 6 can thus advantageously correspond to a so-called hair drying position. Conversely, said second speed F2 and second temperature T2 of the air flow blown by the blowing head 6 may in turn be advantageously predefined and optimized for use of the hairdressing apparatus 1 for the purpose of setting assistance. in the shape of hair. Said second position of the blowing head 6 can thus advantageously correspond to a position known as shaping (styling) of the hair. As such, and in an illustrative and nonlimiting manner, said first temperature T1 of the air flow blown by the blowing head 6 may advantageously be between 64 and 104 ° C, and more advantageously still equal to 84 ° vs. Said first speed F1 of the air flow blown by the blowing head 6 may in turn be advantageously between 35.7 km / h and 99.0 km / h, and even more advantageously equal to 72.8 km / h . Said second temperature T2 of the second flow of air blown by the blowing head 6 may advantageously be between 60 and 100 ° C, and more advantageously still equal to 80 ° C. Said second speed F2 of the air flow blown by the blowing head 6 may in turn be advantageously between 78.1 km / h and 208.3 km / h, and more advantageously still equal to 138.9 km / h .

Advantageously, said automatic adjustment means can be designed and configured so that at said first position of the blowing head 6 correspond a first operating power PI of the heating element 24 and a first speed VI of rotation of the fan 14 of the motor-fan unit 10 of the blower module 5. Said first power PI and first speed VI of rotation can advantageously be predefined and optimized for use of the hairdressing appliance 1, 1 'for drying the hair.

As such, and in an illustrative and nonlimiting manner, said first operating power PI of the heating element 24 may advantageously be between 1000 W and 2000 W, and more advantageously still be equal to 1500 W The first speed VI of rotation of the fan 14 may advantageously be between 13,000 rpm (revolutions per minute) and 17,000 rpm, and more advantageously still be equal to 15,000 rpm. According to the dimensioning of the blower module 5, such a first speed VI of rotation of the fan 14 may advantageously correspond to a flow rate Q1 of the first flow of air blown by the blowing head 6 which is between 50 m ³ / h and 90 m ³ / h, and more advantageously still equal to 70 m ³ / h.

Conversely, said automatic adjustment means may advantageously be designed and configured so that in said second position of the blowing head 6 correspond a second operating power P2 of the heating element 24 and a second speed V2 of rotation of the fan 14 of said motor-fan unit 10. Said second power P2 and second speed V2 may advantageously be predefined and optimized for use of the hairdressing apparatus 1 for the purpose of assisting in the shaping of the hair. As such, and in an illustrative and nonlimiting manner, said second power P2 for operating the heating element 24 may advantageously be between 500 W and 1,500 W, and more advantageously still be equal to 1,000 W. The second speed

V2 of rotation of the fan 14 may advantageously be between 14,000 rpm and 18,000 rpm, and more advantageously still equal to 16,000 rpm. According to the dimensioning of the blower module 5, such a second speed V2 of rotation of the fan 14 may advantageously correspond to a flow rate Q2 of the second flow of air blown by the blowing head 6 which is between 30 m ³ / h and 70 m ³ / h, and more advantageously still equal to 50 m ³ / h. Optionally, in the case where the hairdressing appliance 1 ′ forms a blower brush, in accordance with the second embodiment of the invention, the values given above in terms of speeds, power and flow rate, may be reduced by 60 %, while the values given above in terms of temperature may remain substantially identical.

A hair styling device according to such a variant of the invention is thus of even simpler and more intuitive use for Γ user, since the operation of the blower module 5 and / or of the heating element 24 is thus advantageously predefined, preset, according to the position of the blowing head 6 relative to the handle 2. It is thus possible, during the manufacture of the hairdressing appliance 1, 1 ′ to define in advance the best settings for the hairstyling device 1, 1 'depending on the position of the blowing head 6. The result will therefore be advantageously optimized for the user of the hairstyling device 1, 1', whatever their level of experience in hairdressing.

It is also advantageously possible to provide that the hairdressing device 1,1 'is designed so that the blowing head 6 thereof is able to occupy a third position relative to the handle 2, distinct from said first and second positions, and in which the automatic means for adjusting the operation of the blower module 5 and / or of the heating element 24 are designed to stop the operation of the hairdressing apparatus 1,1 '. Thus, stopping the operation of the hairstyling device 1,1 ′ can be advantageously obtained by a rotation of the blowing head 6 operated by the user, without the latter necessarily needing to act directly on any main on / off switch.

Preferably, the hair styling device 1, 1 'is designed and configured so that said third position (or stop position) corresponds to a position of the blowing head 6 relative to the handle 2 which is intermediate to said first and second positions. For example, in the case where the hairdressing appliance 1, 1 ′ is designed so that the passage of the blowing head 6 from said first position to said second position corresponds to a rotation of an angle of 180 ° of the head blowing 6 around the second axis B-B ', said third position may correspond, in a particularly intuitive manner for Γ user, to a rotation of the blowing head 6 by an angle of 90 ° around said second axis B-B' , from one and / or the other of said first and second positions.

Whether the means for adjusting the operation of the blower module 5 and / or the heating element 24 are manual or automatic, the hair styling device 1.1 ′ preferably comprises, in addition to said adjusting means, means manual activation / deactivation of the heating element 24. Thus, whatever the position of the blowing head 6 (and therefore the air outlet 7, 8 selected), and whatever the chosen setting of the operation of the blower module 5 and / or the heating element 24, it remains possible at any time for the user to stop at will the operation of the only heating element 24, so as to blow towards the hair only a flow of fresh air (that is to say not heated by the heating element 24).

For example, such a manual activation / deactivation means of the heating element 24 can be formed of a conventional electrical switch, of the rocker switch type or of the push button type, positioned at the level of the handle 2 of the hairdressing appliance 1, Γ, and connected between the heating element 24 and its electrical supply circuit. Alternatively and more advantageously, and as illustrated in an example in FIGS. 1 to 5, the manual activation / deactivation means of the heating element 24 comprises a mechanical rocker selector 34, which protrudes from the handle 2 and which is mechanically connected, using a rod (not shown) housed inside the handle 2, to a miniaturized switch 35 arranged within the blower module 5, itself assembled at the first end 3 of the handle 2. By thus deporting part of the manual activation / deactivation means of the heating element 24, space is thus gained within the handle 2, in particular for arranging the heating element 24 there.

In the embodiments illustrated in the figures and described above, the hairdressing device 1, 1 'is preferably designed so that the passage of the blowing head 6 from one position to another is achieved by the user, the latter holding with one hand the handle 2 of the hairdressing appliance 1, 1 ′ and grasping, with the other hand, the blowing head 6 in order to impart to it a rotational movement around its axis of rotation B-B 'relative to the handle 2. However, according to variants not illustrated, it is perfectly conceivable that the rotation of the blowing head 6 is motorized, for example using a controlled electric motor by a dedicated switch positioned at the level of the handle 2, or simply mechanized, for example using a trigger system and cams. In this case, the grip of the handle 2 and the rotation of the blowing head 6 can be carried out by the user in a simplified manner, using one hand.

The operation and use of the device 1.1 ’are for example the following.

The blowing head 6 of the device 1.1 ′ initially occupying its first position relative to the handle 2, the user grasps the handle 2 of the device 1.1 ′ with one hand while preparing to position the device 1,1 'so that the first air outlet 7 from its blowing head 6 is oriented towards his damp hair. The user then actuates the manual means 33 for adjusting the operation of the blower module, and preferably also the operation of the heating element of the appliance 1.1 ′, so that a forced air flow, of preferably hot, either blown towards her hair via the first air outlet 7 of the blowing head 6.

Then, after having thus used the device 1.1 ′ for the desired time, for example until reaching a certain level of drying or pre-drying of his hair, the user grasps, with his other hand, the blowing head 6 in order to impart to it a rotational movement around its axis of rotation B-B 'relative to the handle 2 and to position the blowing head 6 in its second position. The air flow is then blown through the second air outlet 8 of the blowing head 6. By positioning the device 1,1 'so that the second air outlet 8 of the blowing head 6 is oriented towards his hair, the user can, for example, now use the hair styling device 1,1 'to shape his hair.
