Hair styling apparatus with movable head and controlled operation at position of said head

Technical Field

The present invention relates to the general field of hair styling devices, such as home hair styling devices, and more specifically to the field of electric hair styling devices designed to blow an air stream to dry and/or facilitate hair styling.

More specifically, the present invention relates to a hair styling apparatus comprising an air supply module for generating an air flow, a heating element for raising the temperature of the air flow generated by the air supply module, a handle to be held by a hand, and an air supply head connected to the handle.

Background

Hairdressing apparatuses of the type known as hand-held hair dryers comprise a handle and a blower head comprising an air outlet for directing a powerful flow of hot or cold air towards the hair of a user. Even if the hair dryer is mainly used for drying wet hair (hair drying function) by evaporating moisture by the action of the blow air stream, it is also possible to use in combination a certain number of detachable fittings designed to facilitate hair styling (auxiliary styling function). In order to be fixed to the head of the hair dryer and to allow the flow of air blown out of the blowing head to pass through, the above-mentioned fittings, for example of the diffusion or collection type, constitute different endpieces which modify the shape of the flow of air blown out of the blowing head of the hair dryer.

Such prior art hair dryers, while generally satisfactory, still have some drawbacks. Particularly when switching the hair dryer from a dry hair use mode to an auxiliary styling use mode, it is often necessary for the user to adjust the hair dryer to obtain the desired optimum air flow temperature and flow rate. However, the user may forget to make such adjustments, or may not know which optimal adjustment to use to achieve the desired hairstyle result. This not only risks the user not being able to obtain the result desired, but also risks the user damaging the hair quality.

Further, when the hair dryer is switched from the dry hair use mode to the auxiliary styling use mode, it is necessary for the user to perform an assembling/disassembling operation of the parts. This operation proves to be sometimes tiring and there is also a not negligible risk of scalding during the operation of the fitting, and in addition there is a risk of the fitting being lost, when it is not simply tidied up in inaccessible places and when the user wants to use it but is not available.

Detailed Description

The hairdressing apparatus 1, 1' according to the present invention is designed to be held and operated by hand. It therefore relates to a manually, preferably hand-held, hair styling apparatus which can generally provide better operability in the home range for users who lack expertise, in particular styling skills, not only for drying hair, but also for combing and styling hair.

Preferably, according to the first embodiment shown in fig. 1 to 5, the hair dressing apparatus 1 is constituted as a hair dryer (or hair dryer) that dries wet hair of a user while making hair styling easier by blowing hot or cold strong wind directly to the hair. The invention is not limited to this particular embodiment, however, and can also be realized, for example, by a hair styling apparatus 1' which is designed as a blowing comb according to the second embodiment shown in fig. 6 to 10. Alternatively, the present invention can also be implemented with other handheld hair styling devices: including the function of blowing air towards the user's hair, in particular for styling purposes, for example the function of directly touching the hair (combing, straightening, etc.).

For the sake of simplicity, the present specification focuses mainly on a hair-dryer type hair setting device 1 (fig. 1 to 5) and a hair-comb type hair setting device 1' (fig. 6 to 10). Unless indicated to the contrary, the technical features associated with the hair setting device of the first embodiment are preferably interchangeable with the technical features associated with the hair setting device of the second embodiment (and vice versa) with necessary modifications. The same or similar parts between the two embodiments shown in the drawings are referred to in this description by the same reference numerals.

The hair dressing apparatus 1, 1 'according to the present invention comprises a handle 2 (or knob) for manual holding for a user to hold and thereby operate the hair dressing apparatus 1, 1'. The handle 2 extends between a first end 3 and an opposite second end 4, preferably the second end 4 being in the length direction of the first central axis a-a'. In the embodiment shown in the figures, the handle 2 is formed as a single body, or assembled as a single body, generally tubular (for example circular or oval, continuous or discontinuous, in median section), sized and adapted to ensure a better grip of the user's hand.

The hair dressing apparatus 1, 1 'also includes an air supply module 5 for generating a (powerful) air flow, and an air supply head 6 connected to the handle 6, and the air flow generated by the air supply module 5 is guided to the outside of the hair dressing apparatus 1, 1' through the air supply head 6 so that the air flow can be directly sprayed to the hair of the user. Preferably, the blower head 6 extends from one of the first end 3 and the second end 4 of the handle 2, for example from the second end 4. More preferably, as shown in the embodiment shown in the drawings, the air blowing head 6 thus constitutes one end portion of the hair setting apparatus 1, 1'.

More precisely, the blower head 6 has at least one first air outlet 7 and one second air outlet 8, preferably separate from each other (distinct from each other, not coinciding). Preferably, the blower head 6 is arranged so as to be rotatable with respect to the handle 2 between at least a first position, in which the air flow blown out from the blower head 6 is blown out from said first air outlet 7, and a second position, in which the air flow blown out from the blower head 6 is blown out from said second air outlet 8, said components forming a unified subassembly. On the other hand, the hair dressing apparatus 1, 1' according to the present invention is configured such that one of the first air outlet 7 and the second air outlet 8 of the blower head 6 can be selected by moving the blower head 6 (that is, by changing the layout, changing the position) with respect to the handle 2, the blower head 6 blowing out the air flow through the above-mentioned air outlets.

Regardless of the position of the blower head 6 with respect to the handle 2 of the hair styling apparatus 1, 1', the blower head 6 is preferably designed to be permanently attached to the handle 2 of the hair styling apparatus 1, 1', and the blower head 6 cannot be detached from the handle 2 of the hair styling apparatus 1, 1' (in normal use conditions).

Preferably, as in the embodiment shown in the figures, the blower head 6 is rotatably mounted with respect to the handle 2 about a second axis B-B'. In other words, the blower head 6 is preferably connected with respect to the handle 2 according to a rotation axis so that it can rotate with respect to the handle 2. Therefore, the hair setting device 1, 1' is preferably designed and constructed so that the user can select one of the first air outlet 7 and the second air outlet 8 alternately by pivoting the blower head 6 with respect to the handle 2, wherein the blower head 6 blows the air flow through the first air outlet 7 and the second air outlet 8. More preferably, as shown, the second axis B-B 'about which the blowing head 6 rotates relative to the handle 2 coincides with the first axis A-A' along which the handle 2 extends. Furthermore, the second axis B-B ' may also be parallel to said first axis A-A ' (may be more or less offset with respect to the first axis A-A '). Thus, the kinematic principle of the blower head 6 is simple and reliable, and allows the user to intuitively manipulate the hairdressing apparatus 1. Alternatively, the second axis B-B 'intersects the first axis A-A' at an angle typically between 5 ° and 15 °.

That is, other movements of the blower head 6 relative to the handle 2 are clearly foreseeable. For example, according to an alternative not shown in the figures, the blower head 6 can translate with respect to the handle 2, for example along an axis parallel to or coinciding with the first axis a-a 'of the handle 2, or even along an axis perpendicular to said first axis a-a' of the handle 2. The blower head 6 may also perform, for example, a pure translation, a joint slide or a helical translation with respect to the handle 2.

Preferably, the first air outlet 7 and the second air outlet 8 have openings of different geometries. Furthermore, the effective cross-section of the air outlet channel of the first air outlet 7 is determined by a contour (or contours) having a shape different from the contour (or contours) determining the corresponding effective cross-section of the air outlet channel of the second air outlet 8. Therefore, the air flow blown out from the air blowing opening 6 has different air flow profiles depending on the selected

air outlet

7 or 8, thereby enabling the user to use the hair setting device 1, 1' according to at least two different blowing shapes.

Accordingly, the first air outlet 7 and the second air outlet 8 are preferably arranged to blow or emit two different contours of air, a first air flow and a second air flow, respectively, either of which ensures that the user performs different operations on the hair. For example, the first air flow may correspond to a larger flow rate (e.g., set at 70 m) with a wider and diverging profile³H) to ensure that the user can blow the hair quickly. The second air flow may correspond to a relatively small flow rate (e.g., set at 50 m) with a more concentrated and narrow profile³H) to ensure that the user can precisely select the location on his hair to which the second air stream is to be blown. In this way, the user can perform a styling of the hair, such as a wave styling, or, conversely, straightening the hair, skillfully and simply.

For example, in the first embodiment shown in fig. 1 to 5, the hair setting device 1 is constituted as a blower, and the first air outlet 7 has a substantially circular opening (fig. 2), while the second air outlet 8 (fig. 1 and 3) has a substantially elongated oval opening. Based on this, when the air blowing head 6 is located at the first position with respect to the handle 2, the hair styling apparatus 1 can dry wet hair in a conventional manner, and the first air flow blown by the air blowing head 6 is formed in the vicinity of the first air outlet 7, and is substantially cylindrical or conical in profile. When the air blowing head 6 is located at the second position with respect to the handle 2, the hair dressing apparatus 1 can not only dry hair but also easily style hair (for example, comb hair), and the blast of the second air flow blown from the air blowing head 6 near the second air outlet 8 allows the user to accurately select the hair region to be treated, and also enables the hair styling operation to be performed with the air flow.

According to the illustrated way, but not limited to this way, the opening of the first air outlet 7 is preferably capable of generating a first drying air flow, the opening having a first air passage effective cross-section, preferably 707mm²To 1963mm²For example equal to 962mm²(the corresponding opening is a circular first air outlet, preferably 30 to 50mm in diameter, most preferably 35 mm). The opening of the second air outlet 8 preferably has a second air passage effective cross-section, the air circulating in a corresponding passage with said first air passage effective cross-section of said first air outlet 7. For example, the effective cross-section of the second air passage is 240mm²To 640mm²E.g. equal to 360mm²(the second air outlet 8, which corresponds to an oblong opening, has a length of about 60 to 80mm and a width of about 4 to 8mm, preferably a length of about 60mm and a width of about 6 mm).

In a second embodiment, shown in fig. 6 to 10, the hair styling apparatus 1' is configured as a blowing comb, the first air outlet 7 for example having a generally elongated oval opening (fig. 7), to the second air outlet 8 (fig. 6 and 8), which has an opening formed by a large number of holes, generally circular, distributed between the rows of hairs (or hair pins) of the comb. In this way, when the blower head 6 is in said first position with respect to the handle 2, the hair styling apparatus 1' can effect, for example, a preliminary hair drying operation with a first air flow having a wide and dispersed but large flow rate. When the blowing head 6 is in said second position with respect to the handle 2, the hair dressing device 1 'can effect, for example, a final drying operation with a second air flow blowing out from between the combs' bristles (or needles) at a more concentrated but relatively small flow rate.

Accordingly, the hair styling apparatus 1, 1' according to the invention allows the user to select at least one first mode of use (for example, drying hair) and one second mode of use (for example, styling hair) preferably by changing the layout or position of the blower head 6 with respect to the handle 2 (preferably by simply rotating the blower head 6 with respect to the handle 2), which makes it possible to adjust the air flow profile particularly simply and quickly to different operations on the hair.

It is foreseen that the first and second air outlets are fitted to each other in the form of removable (for example by snap, screw, press-fit, etc.) parts in the remaining positions of the blowing head rotatable with respect to the handle (variants not shown in the figures) without going beyond the ambit of the present invention. In fact, this ensures that the user can equip the hairstyling apparatus 1, 1' (instead of having only one air outlet, as is the case with conventional hair drying apparatuses) with two air outlets separated from each other, having different shaped cross-sections, and also ensures that the user can use these air outlets continuously without having to perform operations of removing/remounting the parts, while still retaining the option of replacing one or the other part, these parts being selected according to the specific use of the hairstyling apparatus desired by the user.

Advantageously, however, the blowing head 6 forms a coherent assembly, rather than being intended to be detached by the user, the first air outlet 7 and the second air outlet 8 being constituted by one or more non-detachable parts belonging to the blowing head 6 (in normal use). Thus, by displacing, the position of the blowing head 6 relative to the handle 2 of the device 1, 1 'is changed (preferably by rotation), the user can very significantly select one or the other of the first air outlet 7 or the second air outlet 8, thus advantageously selecting its desired air flow profile, without having to mount or dismount any accessories of the hair styling device 1, 1'. Thus, the user benefits from the easy and quick use of the device 1, 1' and ensures that no elements of the device are lost.

In order to make the hair dressing apparatus 1, 1' easy to use in all cases, particularly for treating the hair at the back of the user's head, the first air outlet 7 and the second air outlet 8 are preferably arranged such that the air flow generated by the air supply module 5 is blown out by the air supply head 6 in a direction intersecting, preferably substantially orthogonal, to the direction in which the first axis a-a ' extends. Particularly preferably, the hair styling apparatus 1, 1' is designed and constructed such that the blower head 6 blows air in substantially the same direction regardless of whether the blower head 6 is in the first position or the second position with respect to the handle 2. Therefore, the user can selectively use the first and second of the air blowing heads 6 of the hair setting device 1, 1 'without adjusting the manual holding position thereof on the handle 2 or changing the overall spatial position of the hair setting device 1, 1'.

Preferably, the blower head 6 is rotatable relative to the handle 2, as in the preferred embodiment shown in the figures, the switching of the blower head 6 from said first position to said second position preferably using a rotation of said blower head 6 through 180 ° about said second axis B-B'. In other words, the air blowing head 6 of the hair dressing apparatus 1, 1 'is designed and constructed such that the first air outlet 7 and the second air outlet 8 of the air blowing head 6 are arranged on both sides of the second axis B-B' along which the air blowing head 6 rotates with respect to the handle. This arrangement facilitates easy and intuitive operation of the hairdressing apparatus 1, 1' by the user.

The first and second positions of the blower head 6 are preferably stable positions, regardless of how the blower head 6 is moved relative to the handle 2, and the blower head 6 cannot be moved out of position in an unexpected manner by a user without active operation. In this case, the hairdressing apparatus 1, 1' preferably includes a device (not shown) for fixing the blower head 6 in the first and second positions with respect to the handle 2, such as a pair of magnets, "dishes" or any other known appropriate method.

It should be pointed out that it is understood that the invention is not limited to a blowing head 6 comprising only two

air outlets

7, 8, in particular rotatable with respect to the handle 2 and arranged at 180 ° with respect to each other only with respect to the second axis B-B', although this assumption is retained in the preferred embodiment shown in the figures. In fact, the blowing head 6 can comprise quite as many air outlets, separated from each other, with different geometrical sections (for example 3 or 4), which the user can select by rotating with respect to the handle and blow the head in correspondingly different positions.

These three or four (or more) air outlets are regularly distributed around the second rotation axis B-B' in sectors of equal angles according to the number of said air outlets. Thus, for example, it is possible to envisage providing three separate air outlets, separated from each other and having a section of different geometry, the air outlets being arranged so that the blower head can be transferred from a first position to a second position and then from this second position to a third position, for example in a manner corresponding to a 120 ° rotation of the blower head about said second axis B-B'. For example, it is also possible to envisage providing four independent air outlets, whose positions are separated from each other and have sections of different geometries, so that the switching of the blowing head from one position to another, for example, corresponds to the way in which said blowing head rotates by 90 ° about said second axis B-B'. Furthermore, the rotation of the blower head about the second axis B-B' to switch the air outlets from a given position to another obviously allows different angles of rotation to be obtained according to the total number of positions/air outlets and the 360 ° ratio.

The air supply module 5 of the hairdressing apparatus 1, 1' preferably comprises an electric fan unit 10, which itself comprises an electric motor 11. The electric fan unit 10 may include a conventional axial fan having a spiral shape. Alternatively, the electric fan unit 10 preferably comprises a spiral centrifugal or centrifugal fan. In embodiments using such a spiral centrifugal or centrifugal fan, a higher internal pressure can be achieved with the same fan size, the air flow rate of which is substantially similar to that of a spiral fan, but such a fan has a lower rotational speed, and therefore the noise generated by the electric fan unit 10 is less. Preferably, the electric motor 11 of the electric fan unit 10 is a brushless motor (a so-called "brushless" motor or a self-controlled synchronous motor with permanent magnets). Such brushless motors are generally more robust and lighter than conventional brushed motors. It is less noisy, more energy efficient, and provides greater flexibility and greater accuracy in adjusting the speed.

Preferably, the air blowing module 5 embedded in the hair styling apparatus 1, 1' is placed inside the handle 2 or inside the air blowing head 6. More preferably, as in the embodiment shown in the figures, the air delivery module 5 of the hair setting device 1 is assembled on the first end 3 of the handle 2, and the air delivery head 6 is movably (preferably rotatably) mounted at the second end 4 of the handle 2 with respect to the handle 2. Thus, blower head 6 preferably extends from second end 4 of handle 2, while blower module 5 extends from first end 3 of handle 2. Preferably, the air delivery module 5 is fixed to the handle 2 at the first end 3 of the handle 2 so that there is no possibility of rotation of the air delivery module 5 relative to the handle 2. Furthermore, the blower module 5 itself can be provided with power supply lines 9, as shown, for example, in fig. 6 to 10. Therefore, the air blowing module 5 of the hair dressing apparatus 1, 1 'is preferably remote from the air blowing head 6 and the handle 2 for holding the hair dressing apparatus 1, 1'. The blower module 5 can be dimensioned accordingly in order to economically produce a large flow of air without affecting the overall dimensions of the blower head 6 and the handle 2. In addition, by distributing the mass on the other side of the handle 2, this arrangement of the blower module 5 facilitates a better balancing of the weight of the molding machine 1, which contributes to the comfort of use.

In case the air supply module 5 is arranged inside the handle 2 or assembled at the first end 3 of the handle 2, the handle 2 may preferably comprise a guiding channel 12 for guiding the air flow generated by the air supply module 5 and conveyed in the direction of the air supply head. Preferably, the guide channel 12 guides the air flow through the handle 2 in the direction of the first end 3 of the handle 2 towards the second end 4. The hair styling apparatus 1, 1' may preferably further comprise a deflector 13, which deflector 13 is designed and arranged to direct the air flow generated by the air supply module 5 from the guide channel 12 of the handle 2 towards the first air outlet of the first handle when the air supply head 6 is in said first position. Vice versa, when the blower head 6 is in the second position, it is directed towards the second air outlet 8.

In the first embodiment shown in fig. 1 to 5, the electric fan unit 10 preferably comprises a centrifugal fan 14, and the blowing module 5 comprises a working chamber 15 in the form of a volute, inside which the electric fan unit 10 is placed. The working chamber 15, as shown in fig. 5, may be defined by the inner walls of the two half-

shells

16, 17 assembled together (for example bolted) and fixed to the first end 3 of the handle. The air delivery module 5 has an air inlet 18 from which the fan 14 draws in ambient air axially into the working chamber 15, while preferably the air outlet communicates with the guide channel 12 of the handle 2, the drawn-in air being forced radially from outside the working chamber 15 into the guide channel 12. The air supply module 5 also preferably comprises a grille (removable and repositionable if desired) for protecting the air inlet 18 of the working chamber 15. As shown in particular in fig. 5, the air intake module 5 is preferably designed and constructed so that the axis of the centrifugal fan 14 of the electric fan unit 10 is substantially orthogonal to the first axis a-a' of the handle 2 in the direction of extension. The air inlet 18 of the working chamber 15 is preferably arranged to suck in ambient air in a direction substantially parallel to the direction of the air flow blown by the blower head 6, and more preferably in the same direction. Of course, it is contemplated that ambient air may be drawn into the working chamber 15 in a secant direction (e.g., substantially perpendicular to the average direction of the air flow blown by the blower head 6) without departing from the scope of this invention.

For the second embodiment shown in fig. 6 to 10, in which the hair setting device 1 is constituted as a blowing comb, the electric fan unit 10 preferably includes a screw-type fan 14. The air supply module 5 is connected at the first end 3 of the handle 2, the air supply module 15 comprising a working chamber 15 having a substantially cylindrical inner wall, the working chamber 15 accommodating the electric fan unit 10. The electric fan unit 10 is arranged such that the axis of the helical fan 14 is parallel to, and preferably coincides with, a first axis a-a' extending longitudinally of the handle 2. The air supply module 5 is provided with an air inlet 18, which may be, for example, a grille, from which air inlet 18 the fan 14 draws in ambient air axially into the working chamber 15, while preferably the air outlet communicates with the guide channel 12 of the handle 2, the drawn-in air being pressed radially from outside the working chamber 15 into the guide channel 12.

Preferably, the blower head 6 comprises a casing 20, the casing 20 defining the shape and contour of the blower head 6 and advantageously of the end of the hair-setting device 1, 1' extending from its handle 2. Preferably, the shape of the casing 20 is designed to allow a manual grip by the user, so that the user can directly and manually press said casing 20 (i.e. the blowing head 6) to rotate the blowing head 6 about the second axis B-B 'with respect to the handle 2 to select one of said first air outlet 7 and second air outlet 8 of said blowing head and thus the respective operating mode of the hairdressing apparatus 1, 1'.

Preferably, the air blowing head 6 includes a nozzle body 19, and the nozzle body 19 is used for guiding the air blown by the hairdressing apparatus 1 to the direction of the user's hair. In the first embodiment shown in fig. 1 to 5, the nozzle body 19 is preferably embedded in the casing 20 (or fairing), said casing 20 being formed, for example, by half shells which can be fastened by snap fastening or assembled by screws. The housing 20 of the blower head 6 is rotated by the user about a second axis B-B ', which causes the nozzle body 19 to also rotate about said second axis B-B'. The casing 20 may be formed so as to give the blower head 6 a particular aesthetic appearance, for example a substantially cylindrical appearance as shown in figures 1 to 5.

Preferably, the casing 20 of the blower head 6 extends longitudinally substantially along a third axis C-C ' orthogonal to the median plane of the blower head 6, said blower head 6 being arranged with respect to the handle 2 such that the second axis of rotation B-B ' of the blower head 6 coincides with the first axis a-a ' extending longitudinally of the handle 2, and such that said first and second axes a-a ' and B-B ' lie in the median plane of the blower head 6. Thus, the housing 20 preferably extends along a third axis C-C ' orthogonal to and having a substantially equal distance from the first axis A-A ' and the second axis B-B ' about which the blower head 6 rotates, both extending longitudinally of the handle.

This particular arrangement provides in particular a good overall balance and contributes to providing the user with a good manoeuvrability, in addition to the symmetrical or quasi-symmetrical aesthetic effect that can be obtained thereby.

In particular, as shown in the cross-section of fig. 5, it is preferred that the mouthpiece 19 extends integrally with a third axis C-C extending longitudinally inside the blower head 6; a first end of the tuyere body constitutes, on the one hand, a first air outlet 7 of the blowing head 6 (which, as mentioned above, preferably has a substantially circular opening) and, on the other hand, a second end, located on the opposite side of the tuyere body, constitutes a second air outlet 8 of the blowing head 6 (which preferably has a substantially elongated oblong opening in a direction perpendicular to the second axis B-B').

In this particular first embodiment, the hair setting device 1 further comprises a deflector 13 which, as previously mentioned, directs the air flow generated by the air supply module 5 alternatively from the guide channel 12 of the handle 2 towards one of said first and

second air outlets

7, 8, depending on where the air supply head 6 is located. As shown in fig. 5, the deflector 13 preferably comprises an elbow 21, which is relatively fixedly mounted on the handle 3 and extends the guide channel 12 of the handle 2 in the direction of the first axis a-a' of the handle 2. The blower head 6 is therefore preferably rotated about the elbow 21 of the deflector 13, causing it to be transferred between said first and second positions.

In a particularly preferred manner, the elbow 21 is formed integrally with the handle 2 (fig. 5), which significantly reduces the number of parts of the hairdressing apparatus 1 and facilitates manufacturing.

As shown in fig. 5, the nozzle body 19 preferably comprises an air inlet hole 22 which is dimensioned to cooperate with an elbow 21 of the deflector and by means of which said elbow 21 passes through the nozzle body 19 in the direction of the second axis B-B' of rotation of the blowing head 6. The elbow 21 and the nozzle body 19 are arranged with respect to each other as follows: when the blower head 6 is in said first position, the elbow 21 directs the air flow in the nozzle body 19 towards the first nozzle body end constituting the first air outlet 7 of the blower head 6, while preferably preventing air leakage in the direction of the opposite second nozzle body end. Vice versa, the elbow 21 and the nozzle body 19 are mutually arranged according to one another as follows: (after rotating the rotatable blower head 6 by 180 ° about the second axis B-B') when the blower head 6 is in said second position, the elbow 21 directs the air flow in the nozzle body 19 towards the second nozzle body end constituting the second air outlet 8 of the blower head 6, while preferably preventing air leakage in the direction of the opposite first nozzle body end (fig. 5). As shown, the deflector 13 (and in particular the elbow 21 thereof) and the nozzle body 19 are configured to direct the airflow in the guide channel 12 of the handle 2 in a 90 ° deflected manner towards either of the first and

second air outlets

7, 8.

Obviously, it is foreseeable that the blower head 6 of the hair setting device 1 has a different design, for example as shown in fig. 6 to 10 in relation to the second preferred embodiment of the hair setting device 1, 1' according to the present invention.

The hair setting device 1' shown in fig. 6 to 10 is constructed as a blowing comb, the blowing head 6 here preferably having an outline substantially similar to a conventional comb. In this case, the blower head 6 extends along a fourth axis D-D 'parallel to, and preferably coinciding with, a second axis B-B' along which the blower head 6 rotates with respect to the handle 2. Furthermore, as shown, the blower head 6 is arranged relative to the handle 2 such that a second axis of rotation B-B 'of the blower head 6 coincides with a first axis A-A' of the handle 2 extending in the longitudinal direction.

As shown in particular in fig. 10, the blower head 6 may comprise a tuyere body 19, which tuyere body 19 is not in this case mounted in the form of a separate part in a housing 20 of the blower head 6, but which tuyere body 19 is defined directly by the inner wall of said housing 20. The housing 20 may be formed of a plurality of shell-shaped elements assembled together (e.g., by snap or screw fastening) in a similar manner to the first embodiment. Said nozzle body 19 then preferably extends along a fifth axis E-E 'orthogonal to a fourth longitudinal axis D-D' inside the blower head 6. The first tuyere body end forms, on the one hand, a first air outlet 7 of the blowing head 6 and, on the other hand, the opposite second tuyere body end forms a second air outlet 8 of the blowing head 6.

According to another embodiment, the housing 20 may include at least one post (not shown) disposed at an edge of the housing 20 that is configured to contact hair during a hair styling operation. The post is preferably heatable or at least capable of transferring heat from the drying air stream flowing in the blower head 6 to the hair. For example, the columns may be made of a heat conductive material, such as a metal material (steel, aluminum, etc.), and are in direct contact with the drying air flow flowing inside the tuyere body 19. For example, the post may extend through the entire housing 20 on one side into the interior of the nozzle body 19 for contact with the drying air stream and on the other side out into contact with the hair. The protruding edges of such posts may be contacted with the hair during styling, preferably by heating the edges, which gives the hair the effect of a webbing. By this outstanding effect, a bundle of hair can be formed into a harmonious wave, just like the wave we produce by rubbing a ribbon with a blade when preparing a delicate gift wrapping. Preferably, the housing comprises two posts opposite each other, substantially parallel and arranged on either side of the fourth axis D-D', so as to enable a webbing-like hair-waving effect to be achieved by a person having little or no experience in operating the hair setting device.

The first air outlet 7 of the blower head 6 has a substantially elongated oval opening substantially parallel to the direction of a fourth axis D-D' extending longitudinally of the blower head 6 (fig. 7). The second air outlet 8 of the blowing head 6 can, for example, consist of a plurality of holes, generally circular in shape, distributed between the rows of combs (or needles) (figures 6 and 8).

In this second particular embodiment, the hairdressing apparatus 1' also comprises a deflector 13, which deflector 13 directs the air flow generated by the air supply module 5 from one of said first and

second air outlets

7, 8 to the other from the guide channel 12 of the handle 2, depending on where the air supply head is located. As shown in fig. 5, the deflector 13 preferably comprises an elbow 21 formed as a segment of closed conical section, with its inner side wall provided with an axial opening. The elbow 21, which is fixed with respect to the handle 2, extends along the first axis a-a' and extends the air guide channel 12 of said handle 2 to protrude beyond the second end 3.

As shown in fig. 5, the nozzle body 19 preferably comprises air inlet holes which are dimensioned to fit the elbow 21 of the deflector 13 and by means of which said elbow 21 can pass through the nozzle body 19 in the direction of the second axis B-B' of rotation of the blowing head 6. The corresponding arrangement and disposition of the elbow 21 and the nozzle body 19 according to the second embodiment of figures 6 to 10 is similar, or even identical, to that of the elbow 21 and the nozzle body 19 according to the first embodiment of figures 1 to 5, giving substantially the same effect.

Preferably, one and/or the other of the first air outlet 7 and the second air outlet 8 may also be provided with one or more baffles, more or less inclined, and preferably fixedly mounted, so designed and configured as necessary to even out the velocity/flow distribution of the air flow profile blown out of the air outlets. For example, in the embodiment shown in the figures, the first air outlet 7 opening is provided with a fin deflector 23, which, in combination with its opening geometry, may be adapted to the use of the hair-styling apparatus 1, 1' for drying/pre-drying purposes. In the first embodiment of fig. 1-5, the vane deflector 23 is preferably integrally formed with the nozzle body 19. Alternatively, the vane baffle 23 is a separate additional component, as shown in the second embodiment of fig. 6-10. Preferably, the geometry of the opening of the second air outlet 8 is adapted to the use of the hairdressing apparatus 1, 1' for styling or assisted styling purposes, which is not equipped with fin deflectors per se.

The hair setting device 1, 1' further comprises a heating element 24 for heating the air flow generated by the air supply module 5. The heating element 24, which is preferably embedded inside the hair styling apparatus 1, 1', can be housed inside the air delivery head 6 or inside (i.e., inside) the handle 2. More preferably, the heating element 24 is (at least partially) housed within (i.e. inside) the handle 2, and even more preferably, as in the embodiment shown in the figures, is arranged in a guide channel of the handle 2 in such a way as to be interposed between the air flows generated by the air supply module 5. This arrangement allows to considerably reduce the size and weight of the blower head 6 while simplifying the design. The electric heating elements are generally elements operating according to the joule effect principle, the power preferably being greater than 500W. Preferably, heating element 24 comprises at least one heating resistor made of a conductive wire (e.g., nichrome) wound around an insulating core. In the preferred embodiment shown in the figures, the heating element 24 is more precisely constituted by an insulating core 25 (for example made of mica) wound with a cross-section of metal wire (not shown) and provided with fixing fins at its ends. Preferably, the hair styling apparatus 1, 1' further comprises a thermal insulator 26, for example a tubular member with a circular bottom surface, and the heating element 24 is arranged inside this thermal insulator 26, which is heated by the restraining handle 2 to protect the user in particular from burns. As shown, the inner wall of the thermal insulator 26 preferably constitutes all or part of the channel of the aforementioned guide channel 12.

Preferably, the hairdressing apparatus 1, 1' further includes an electronic module 27. Which does not require user manipulation nor contact by the user, the electronic module 27 is preferably designed to interact (directly or indirectly) with all or part of the components that make up the hairdressing apparatus 1. Which is typically a circuit board, an electronic circuit, a printed circuit ("PCB") or a collection of electrical, electronic or electromechanical components inside the hairdressing apparatus 1, 1'. The electronics module 27 is used to ensure a specific power supply mode (e.g., with current filtering, conversion or rectification functions) to ensure control, command or even regulation of one and/or other functional components of the hairdressing apparatus 1, 1'. Optionally, the electronics module 27 may include components such as a battery, a display, one or more microcontrollers, and the like. The electronic module 27 can also be optionally connected to a number of sensors and inductive elements distributed in the hairdressing apparatus 1, 1' for measuring, monitoring physical parameters (temperature, voltage and current, air flow rate/quantity, rotation speed of the fan 14 of the air supply module 5, etc.) related to the function of the hairdressing apparatus 1, 1', thereby better controlling the operation of the various functional components of the hairdressing apparatus 1, 1 '.

In a more preferred manner, the electronic module 27 is designed as an electronic module for controlling the operation of the air supply module 5 and/or the heating element 24 of the hairdressing apparatus 1, 1'. In fact, in order to control the air supply module 5 and/or the heating element 24 of the hairdressing apparatus 1, 1', respectively, according to the technology employed, specific control needs to be implemented on the electronic module(s) or electronic circuit.

For example, when the electronic module 27 is designed to control the heating element 24, the electronic module 27 may comprise electrical supply and/or specific regulating (power, temperature, etc.) circuits for controlling said electronic module. As mentioned above, in the preferred case in which the air supply module 2 comprises a brushless motor 11, the control of said brushless motor 11 can be ensured by the electronic module 27. In this case, the electronics module 27 can be designed to control the commutation of the current in the stator winding (phase control) on the basis of position sensor data (e.g. hall effect), to ensure autonomous regulation of the rotational speed, etc.

Preferably, such electronic module 27 is preferably arranged inside the blower head 6, preferably outside the air flow inside the blower head 6, as in the first preferred embodiment shown in fig. 1 to 5. Preferably, the blower head 6 comprises a dedicated compartment 28 for housing said electronic module 27.

This arrangement helps to limit the overall size of the hair styling apparatus 1, 1', particularly in the case where the electronic module 27 is designed to control the air supply module 5 and/or the heating element 24, which is then located outside the air supply head 6. In the case of the heating element 24 being located inside the handle 2 and/or the blower module 5 being mounted inside the handle 2 or at one end of the handle 2, as previously described, the electronic module 27 is preferably located separately from the heating element 24 and/or the blower module 5 it controls, which makes it possible to reduce the overall dimensions of the handle 2 and/or the blower module 5 connected thereto as much as possible.

However, given the moving (preferably rotating) characteristics of the blowing head 6, it may be difficult to ensure a simple and robust electrical connection, both with the heating element 24 and/or the blowing module 5 outside the blowing head 6 (or any other functional component of the hairdressing apparatus 1, 1' that may be connected to the electronic module 27 and arranged outside the blowing head 6) on the one hand and with the electronic module arranged inside the blowing head on the other hand. This is why, in the first preferred embodiment shown in figures 1 to 5, electronic module 27 is preferably mounted inside blower head 6 so as to remain relatively stationary with respect to blower module 5 and/or heating element 24 outside blower head 6. In this case, as shown in fig. 5, the tuyere body 19 may be provided with an auxiliary hole 29, which is opposite to the air intake hole, and the elbow 21 of the baffle plate 13 passes through the tuyere body 19 through the auxiliary hole 29. The height of the auxiliary hole 29 is flush with the nozzle body 19 or partially exceeds the nozzle body 19, so that the electronic module 27 can be fixed to the elbow 21 directly or indirectly via the support 30. Obviously, other suitable mounting means are foreseen. For example, depending on the size, the electronics module 27 may be mounted on the back of the elbow 21 of the baffle 13.

The electrical connection between the heating element 24 and/or the blower module 5 and the electronics module 27 provided in the blower head 6 can thus be realized very simply, for example using conventional electrical wires (not shown), i.e. without the risk of damaging the wires by twisting, and without the use of complex moving electrical connection means (for example of the rotary-connected connector type). Therefore, the manufacturing cost of the hairdressing apparatus 1 can be reduced and the reliability can be improved.

Although the electronic module 27 is arranged inside the blower head 6 and preferably outside the air flow passing through the blower head 6, in the case where 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 blower head 6, the temperature of the electronic module 27 is likely to rise significantly as a result. Furthermore, even if the heating element 24 is not activated or the device is not equipped with such a heating element, the electronic module 27 is likely to self-heat under the influence of the current during normal operation. If the temperature of the electronic module 27 is not controlled beyond a certain threshold, the risk of malfunctioning of the electronic module 27 and even of the entire apparatus is in any case increased.

For this reason, the hair setting device 1, 1' may particularly preferably include a branch passage 31, and the branch passage 31 serves to catch a part of the air flow generated by the air blowing module 5, thereby ensuring cooling of the electronic module 27. In order to ensure forced cooling of the electronic module 27, this portion of the air flow is directed and blown as close as possible to the electronic module, so that the diversion channel 31 is designed and constructed to collect and divert a portion of the forced air flow generated by the air supply module 5, if necessary, before the air flow is heated by the heating element 24.

In case the blower module 5 is arranged in the handle 2 or at the first end 3 of the handle 2, said diversion channel 31 preferably extends at least partially in the handle 2. Thus, the shunt channel 31 is preferably integrated in the handle 2. As a further preferred way, the hairdressing apparatus 1, 1 'can be arranged such that the guide channel 12 and the flow dividing channel 31 extend in parallel to each other within the handle, preferably along the first axis a-a' of the handle.

For example, in a first preferred embodiment shown in fig. 1 to 5, on the one hand a diversion channel 31 opens at the air outlet of the working chamber 15 of the air supply module 5 for capturing part of the air flow (cold air, i.e. air that has not been heated by the heating element 24) generated by said air supply module 5; on the other hand directly adjacent to the electronic module 27 provided in the blower head 6. As in the embodiment shown in fig. 5, the shunt channel 31 may occupy, in whole or in part, the free space formed between the inner wall of the handle 2 and the outer wall of the thermal insulator 26 in the length direction of the handle 2. This arrangement also facilitates the cooling of the handle 2, which improves the comfort of use of the hairdressing apparatus 1, 1'. Said diversion channel 31 may also preferably extend, at the level of the blower head 6, between a double wall 32 formed by the back of the elbow 21 and then through said support 30, as previously mentioned, the electronic module 27 being fixed to the elbow 21 by means of the support 30.

Preferably, the hair-styling apparatus 1, 1 'can furthermore comprise a circuit for re-blowing a part of the air stream captured in the (main) air stream blown by the blowing head 6, so that part of the air stream captured by the diversion channel 31 and distributed to the electronic module 27 for cooling can be blown directly towards the user's hair through the

air outlets

7 and 8 in the blowing head. 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 out of the blower head 6. For example, the nozzle body 19 of the blower head 6 may be provided with holes (not shown) for re-ejecting a portion of the collected airflow directly inside the nozzle body 19, preferably downstream of the elbow 21 of the deflector 13. Alternatively (or additionally), the housing 20 of the blower head 6 can be provided with an air vent (or equivalent structure) through which all or part of the trapped air flow can escape from the blower head 6, i.e., from the hairdressing apparatus 1, 1'. In this way, the part of the air flow that cools the electronic module 27 is discharged from the hairdressing apparatus 1, 1 'without affecting (or at least without significantly affecting) the temperature of the (main) air flow that is directly blown from the blower head 6 towards the user's hair.

Typically, the flow dividing channel 31 is dimensioned to allow a flow of air in the range of 1 to 10m³The flow rate/h is passed through, so that the electronic module 27 is effectively cooled.

According to the invention, the hair styling apparatus 1, 1' comprises automatic adjustment means 33 for operating the air supply module 5 and/or the heating element 24, which automatic adjustment means 33 (automatically) control the air supply module 5 and/or the heating element 24 depending on the position of the air supply head 6 with respect to the handle 2. In other words, these adjustments are not made directly by the user, but indirectly by changing the position of the blower head 6 relative to the handle 2. Said automatic adjustment means 33 thus cooperate (possibly through the aforesaid electronic module 27) with the blowing module 5 and with the heating element 24, so as to automatically adjust accordingly to the change in position of the blowing head 4 with respect to the handle 2 made by the user.

Such automatic adjustment means 33 can also be obtained by any other known means using said automatic control function. For example, said automatic adjustment means 33 may comprise in particular one or more switches or contactors (electrical, optical, mechanical, even magnetic) and/or one or more potentiometers, and/or one or more position sensors for sensing the position of the blower head 6 with respect to the handle 2. Which are normally provided at the interface between the blower head 6 and the handle 2 and are electrically connected to the blower module 5 and/or to the heating element 24 (possibly through the aforementioned electronic module 27), said automatic adjustment means 33 being able to be activated or deactivated depending on the position of the blower head 6 with respect to the handle 2, so as to adjust the relative operation of the blower module 5 and the heating element 24. In this way, the respective operation of the blowing modules and/or heating elements can be preset, preferably according to said first and second position of the blowing head 6, preferably simultaneously corresponding to different preset functions.

Preferably, said automatic adjustment means 33 of the blowing module 5 and of the heating element 24 are designed and arranged so that said first position of the blowing head 6 corresponds to a first speed F1 and a first temperature T1 of the air flow blown by the blowing head 6 (i.e. through the first air outlet 7 of the blowing head 6). Likewise, said automatic adjustment means 33 may preferably be designed and configured so that said second position of the blower head 6 corresponds to a second speed F2 and a second temperature T2 of the air flow blown out by the blower head 6 (in this case through the second air outlet 8 of the blower head 6).

In a more preferred manner, said first speed F1 and second speed F2 of the air flow blown by the blower head 6 are different from each other, and said first temperature T1 and second temperature T2 of the air flow blown by the blower head 6 may also be different from each other. It is however foreseen that said automatic adjustment means 33 may be arranged in cooperation with the blower module 5 and the heating element 24, so that the air flow is automatically blown out at the same speed or temperature, irrespective of the position of the blower head 6, and thus of the selected

air outlet

7 or 8, and of the shape of the opening of the

air outlet

7 or 8.

In this way, either of said first and second positions of the blower head 6 can be automatically paired with the speed-temperature of the blow-out air flow, which can also preferably be preset and optimized according to the specific use of the hairdressing apparatus 1, 1'. For the purpose of drying hair using the hair dressing apparatus 1, the first speed F1 and the first temperature T1 of the air flow blown out by the blower head 6 can preferably be preset and optimized. Said first position of the blower head 6 preferably corresponds to a so-called hair drying position. Also, the second speed F2 and the second temperature T2 of the air flow blown by the air blowing head 6 can preferably be preset and optimized in order to achieve styling of the hair using the hair setting device 1. Said second position of the blower head 6 therefore preferably corresponds to a so-called hair styling position.

Here, said first temperature T1 of the air flow blown by the blower head 6 is preferably, by way of illustration and not by way of limitation, between 64 and 104 ℃, more preferably equal to 84 ℃. Said first speed F1 of the air flow blown by the blower head 6 is preferably between 35.7km/h and 99.0km/h, more preferably equal to 72.8 km/h. Said second temperature T2 at which the blower head 6 blows the second air flow is preferably between 60 and 100 c, more preferably equal to 80 c. Said second speed F2 of the air flow blown by the blower head 6 is preferably comprised between 78.1km/h and 208.3km/h, more preferably equal to 138.9 km/h.

Preferably, said automatic adjustment means 33 are designed and arranged so that the blower head 6, in said first position, corresponds to the first power P1 of the heating element 24 and to the first speed of rotation V1 of the fan 14 of the motorized fan unit 10. For the purpose of using the hair dressing apparatus 1, 1' for drying hair, the first power P1 and the first rotational speed V1 can preferably be preset and optimized. Here, said first power P1 of the heating element 24 is preferably comprised between 1000W and 2000W, more preferably equal to 1500W, by way of illustration and not by way of limitation. The first speed of rotation V1 of fan 14 is preferably between 13000rpm and 17000rpm, more preferably equal to 15000 rpm. This first speed V1 of the fan 14 corresponds to the flow Q1 of the first air flow blown by the blower head 6, preferably at 50m, according to the size of the blower module 5³H to 90m³More preferably equal to 70m³/h。

Likewise, said automatic adjustment means 33 are preferably designed and arranged so that the blower head 6, in said second position, corresponds to a second power P2 of the heating element 24 and a second speed V2 of the fan 14 of the motor-fan unit 10. For the purpose of use of the hair styling apparatus 1 for assisting hair styling, the second power P2 and the second rotational speed V2 can preferably be preset and optimized. In this case, said second power P2 of the heating element 24 is preferably comprised between 500W and 1500W, more preferably equal to 1000W, by way of illustration and not by way of limitation. The speed of rotation V2 of fan 14 is preferably between 14000rpm and 18000rpm, more preferably equal to 16000 rpm. This second speed of rotation V2 of the fan 14 corresponds to the flow rate Q2 of the second air flow blown by the blower head 6, which is preferably 30m, according to the size of the blower module 5³H to 70m³Between/h, more preferably equal to 50m³/h。

If necessary, according to the second embodiment of the present invention, in the case where the hair setting device 1' is configured as a blowing comb, the above-mentioned values of speed, power and flow rate can be reduced by 60%, while the above-mentioned values of temperature can be kept substantially the same.

Therefore, the hair setting device 1, 1' according to the present invention is simpler and more intuitive for the user, since the operation of the air supply module 5 and/or the heating element 24 can be preset, pre-adjusted depending on the position of the air supply head 6 with respect to the handle 2. Therefore, an optimum adjustment operation for the hair setting device 1, 1 'is set in advance in accordance with the position of the blower head 6 in the manufacturing process of the hair setting device 1, 1'. Therefore, the user of the hair dressing apparatus 1, 1' can greatly optimize the styling result regardless of the hair styling experience.

Preferably, the hair styling apparatus 1, 1 'is designed such that its blowing head 6 can be positioned in at least one third position (even a fourth position) with respect to the handle 2, different from the first and second positions, in which the automatic adjustment means 33 of the blowing module 5 and the heating element 24 are designed to stop the operation of the hair styling apparatus 1-1'. In other words, said automatic adjustment means 33 are designed and configured to cooperate with the blower module 5 and with the heating element 24 so that, when the blower head 6 is in said third position with respect to the handle 2, both the rotation speed of the fan 14 of the group 10 of electric fans of the blower module 5 and the power of the heating element 24 are zero. For this purpose, the automatic adjustment device 33 can be designed, for example, to interact directly with the respective supply circuits of the blower module 5 and the heating element 24, or, if necessary, with the aforementioned electronic control module 27. In this way, the user can advantageously stop the operation of the hairdressing apparatus 1, 1' simply by changing the position (preferably simply by rotating) of the blower head 6 with respect to the handle 2, without having to act directly on any conventional on/off switch.

Preferably, the hair styling apparatus 1, 1' is designed and constructed such that said third position (or stop position) corresponds to the position of the blowing head 6 with respect to the handle 2 between said first and second positions. In this case, for example, the hair-styling apparatus 1, 1' is designed to switch the blower head 6 from said first position to said second position by rotating it through 180 ° about the second axis B-B ', the switching to said third position being therefore intuitive for the user, which corresponds to the blower head 6 being reached by rotating it through 90 ° about said second axis B-B ' from one and/or the other of said first and second positions. Alternatively, in the case where the blower head 6 is movable with respect to the handle 2 without being rotated, for example with respect to the handle 2 in translation between said first and second positions, it is foreseen that said third stop position corresponds to a position of the blower head 6 equidistant from said first and second positions in the direction of translation.

Optionally, and as shown in the figures, the hair setting device 1, 1' may further comprise manual adjustment means 34 for the user to adjust the air supply module 5 and/or the heating element 24. The adjustment devices concerned, for example of the rocker switch type, push button type and/or slide type or rotary disk type, are acted upon directly by the user if necessary for precise adjustment of the blower module 5 and/or the heating element 24. For example, the manual adjustment device 34 may be designed and configured to cooperate with the air supply module 5 and/or the heating element 24 in order to more finely adjust the rotational speed of the fan 14 of the air supply module 5 and/or the power of the heating element 24. Furthermore, the manual adjustment means 34 can be designed and configured to start/stop the hairdressing apparatus 1, 1', i.e. to stop operation completely, in which case it is foreseen that the blower head 6 does not have to be designed with a (third) stop position.

As regards the position of the manual adjustment device 34, it can be, for example, at the handle or at the blower module 5, in the latter case, as shown, assembled at the first end 3 of the blower module 5.

In addition to said automatic adjustment means 33 for the air supply module 5 and the heating element 24, the hairdressing apparatus 1, 1' preferably also comprises manual start/stop means for the heating element 24. In this way, the user can at any time stop the operation of the heating element 24 alone, so as to blow only cold air (i.e. air not heated by the heating element 24) towards the hair, regardless of the position of the blower head 6 (i.e. whether the

air outlet

7 or 8 is selected) and regardless of the operating adjustment of the blower module 5 and/or the heating element 24.

Such manual activation/deactivation means of the heating element 24 can, for example, consist of a conventional electric switch, rocker-like switch or push-button-like switch provided at the handle 2 of the hairdressing apparatus 1, 1', which is connected to the heating element 24 and its power supply circuit. Alternatively and more preferably, as shown in fig. 1 to 5, the manual activation/deactivation means of the heating element 24 comprise a mechanical rocker switch 34, which protrudes from the handle 2 and is mechanically connected, using a pull rod (not shown) housed inside the handle 2, to a microswitch housed inside the blower module 5, which microswitch 35 is itself assembled at the first end 3 of the handle. By removing a part of the manual activation/deactivation means of the heating element 24 in this way, space can be made available for the interior of the handle 2, which is mainly used for arranging the heating element 24.

In the embodiment shown in the drawings and described above, hair dressing device 1, 1' is preferably designed to let the user switch air delivery head 6 from one position to another, and the user holds handle 2 of hair dressing device 1, 1' with one hand and air delivery head 6 with the other hand, so that air delivery head 6 rotates around rotation axis B-B ' with respect to handle 2. However, according to variants not shown, it is fully foreseen that the rotation of the blower head 6 (or translation according to the different movement modes selected) can be motorized, for example by means of an electric motor controlled by a switch provided on the handle 2, or simply mechanized, for example by means of a triggering system and a cam. In this case, the user can grip the handle 2 with one hand in a simplified manner while effecting rotation (or translation) of the blower head 6.

The following are examples of the function and use of the hair dressing apparatus 1, 1' in connection with the embodiments shown in the drawings.

The air blowing head 6 of the hair styling apparatus 1, 1 'is initially located in a first position with respect to the handle 2, and the user grasps the handle 2 of the hair styling apparatus 1, 1' with one hand while preparing to position it: the first air outlet 7 of its blower head 6 is directed in the direction of the wet hair. Thanks to the automatic adjustment means 33 for adjusting the blower module 5 and the heating element 24, the blower head 6 is able to blow an optimized flow of air in the direction of the user's hair, for example for pre-drying or drying the hair.
