The hair styling device 1 according to the invention, a non-limiting embodiment of which is shown by way of example in the drawings, is a portable hair styling device designed to be picked up and handled by hand. This is a hair styling device 1, which is preferably intended for home use by users without specific professional hair styling skills, ie both in terms of drying and styling hair, or also in terms of hair shaping. Preferably, the hair styling device 1 is designed so that the user uses the hair styling device 1 on his or her own hair. However, it is perfectly conceivable that the hair styling device 1 is designed for use by a user on other people's hair.

As will be understood from the following, the hair styling device 1 is configured to generate the airflow F according to at least two different blowing modes, i.e. at least a first blowing mode and therefore a second blowing mode different from the first blowing mode. ) and means for generating an airflow (F) designed and configured to generate an airflow (F). It is therefore advantageously a “multi-mode” or “multifunctional” device, designed and configured to blow the airflow F towards the hair according to at least two different blowing modes which can be alternately selected by the user. “Different blowing modes” preferably means that the hair styling device 1 thereby enables different operations to be performed on the hair depending on the selected blowing mode, for example hair drying operations or hair shaping operations. To this end, it is understood as a blowing mode that blows different air currents, for example, depending on their shape, direction and/or intensity.

The hair styling device (1) has at least a first air-blowing outlet (2) for blowing the air current (F) out of the hair styling device (1), for example in a first of the blowing modes, and, for example, and a second air-blowing outlet 3 for blowing the airflow F out of the hair styling device 1 in the second of the blowing modes. The first and second air-blowing outlets 2, 3 are separate from each other, preferably spaced apart from each other, preferably opposite each other. As in the embodiment shown in the figures, the hair styling device 1 advantageously has a first side 4 with said first air-blowing outlet 2 and said second air-blowing outlet 3 It has a second side 5 having ). The first and second sides 4 , 5 are different, preferably opposite sides of the hair styling device 1 . Advantageously, the first and second air-blowing outlets 2 , 3 do not exist alternately, but simultaneously (i.e. they are both permanently present on the hair styling device 1 ). Typically, the hair styling device 1 comprises a casing 6 , for example made of plastic, the outer side of which corresponds to at least the first and second sides 4 , 5 of the hair styling device 1 . forms part of The casing 6 has an outer surface (defined by said outer side) which forms at least part of the outer surface of the hair styling device 1 .

Preferably, the blowing modes correspond to different paths of the airflow F inside the hair styling device 1 . Accordingly, the hair styling device 1 is preferably designed and constructed in such a way that the airflow F takes different (aerodynamic) paths through the hair styling device 1 depending on the blowing mode selected by the user. Therefore, the air flow F is advantageously inside the hair styling appliance 1 in the first blowing mode until it is blown out of the hair styling appliance 1 via the first air-blowing outlet 2 ( FIG. 6 ). follows at least the first path of In the second blowing mode, the air flow F is advantageously directed to the hair styling appliance in the first blowing mode until it is blown out of the hair styling appliance 1 via the second air-blowing outlet 3 ( FIG. 8 ). (1) Follows another internal path, i.e. a path that is at least partially different from the path(s) taken by the air current F. The embodiment of these different aerodynamic paths advantageously allows for the definition of very different blowing modes, especially as a function of the configuration and shape selected for the first and second air-blowing outlets 2, 3, their relative arrangement, etc. Make it possible. In particular, this means that the air currents F are thereby blown out of the hair styling device 1 in different respective directions, possibly in opposite directions, for example through the air-blowing outlets 2, 3 spaced apart from each other. It makes it possible to provide a blowing mode.

As in the embodiment shown in the figures, the first blowing mode can advantageously correspond to the mode of operation of the hair styling device 1 in the “blower brush” mode (in particular FIGS. 3 , 6 and 7 ). while the second blowing mode can advantageously correspond to the operating mode of the hair styling device 1 in the “hair dryer” mode (in particular FIGS. 5 , 8 and 9 ). Of course, the present invention is not limited to this specific blowing mode, and other blowing modes may be considered depending on the intended use of the hair styling device 1 for drying and/or shaping hair. Moreover, in practice, the number of different blowing modes is not limited to two. Moreover, the same given blowing mode can possibly correspond to a plurality of different paths of the airflow F inside the hair styling device 1 .

The hair styling device 1 includes a handle 7 (or grip) for manual gripping, which is intended to be manually held by a user in order to handle the hair styling device 1 . Advantageously, the handle 7 formed by part of the casing 6 of the hair styling device 1 is typically positioned between the first end 8 and the opposing second end 9, preferably along the average extension axis ( It extends longitudinally along A-A'). The handle 7 advantageously has an elongated shape in such a way that an adult user can hold it with his entire hand. The hair styling device 1 further includes a blow head 10 that blows the airflow F out of the hair styling device 1 toward the hair. The blow head 10 connected to the handle 7 is arranged in such a way that the air current F is thus advantageously intended to be blown out of the hair styling device 1 via the blow head 10 towards the hair. It has first and second air-blowing outlets (2, 3). The blow head 10 advantageously formed by part of the casing 6 of the hair styling device 1 advantageously forms, or at least serves to form, the first side 4 of the hair styling device 1. It preferably has at least one first side with a first air-blowing outlet (2). The blow head 10 advantageously forms, or at least contributes to form, the second side 5 of the hair styling device 1, preferably the second side having a second air-blowing outlet 3. also has. Advantageously, the blow head 10 has a lower end (first end) at which the blow head 10 is connected to the handle 7 and thus preferably extends the handle 7 beyond the first end 8 of the blow head. ) and the opposite free upper end (second end) along the average extension axis (B-B'). Depending on the shape and size of the blow head 10, the average extension axis B-B' may form the longitudinal extension axis of the blow head 10. As in the embodiment shown in the figures, the mean axis of extension B-B' of the blow head 10 is advantageously parallel to the mean longitudinal axis A-A' of the handle 7. They are on the same line (merged). The hair styling device 1 is then advantageously generally parallel to the average longitudinal extension axis A-A' of the handle 7 and the average extension axis B-B' of the blow head 10. It extends along the average extension direction on the same line.

As in the embodiment shown in the figures, the first blowing mode advantageously corresponds to the mode of operation of the hair styling device 1 in the “blower brush” mode, where the blow head 10 typically performs, in particular, its brushing, and a mechanical hair-binding element (11) configured to mechanically interact with the user's hair for styling and/or combing. Advantageously by the first side of the blow head 10 (which forms or contributes to form said first side 4 of the hair styling device 1 ) which also has a first air-blowing outlet 2 The supported mechanical hair-engaging element 11 may comprise a plurality of rows or bars of brush bristles and/or pins. Preferably, as in the embodiment shown in the figures, the first air-blowing outlet 2 comprises a plurality of air-blowing holes, i.e. a plurality of air-blowing outlet parts, said blowing holes It is arranged between brush bristles or pins included in the mechanical hair-engaging element (11). For example, the air-blowing holes may each be formed by a slot (straight or curved). Accordingly, the airflow F can be optimally blown towards the hair when engaged with the mechanical hair-binding element 11 during a hair styling operation. Preferably, the first air-blowing outlet 2 extends longitudinally along the average extension axis B-B' of the blow head 10. For example, the first air-blowing outlet 2 may then comprise a plurality of air-blowing holes each in the form of a slot and arranged staggered along the average extension axis B-B' of the blow head 10. (Figure 3). Respectively, the second blowing mode advantageously corresponds to the mode of operation of the hair styling device 1 in the “hair dryer” mode, and the second air-blowing outlet 3 preferably corresponds to the above-mentioned average blowing outlet 3 of the blow head 10. It preferably has a distinctive air-blowing opening extending longitudinally along the extension axis B-B'. Accordingly, the second air-blowing outlet 3 of the blow head is generally designed for blowing an air stream F in the form of an air blade, as shown by way of example in FIGS. 1, 2 and 4 to 9. It has a rectangular, elongated opening. As an alternative, the second air-blowing outlet 3 may have a generally circular opening for blowing the air stream F, for example in a substantially cylindrical or frustoconical shape. Preferably, the second air-blowing outlet 3 is formed, for example, by a fixed (non-movable) or detachable (removable) nozzle 12, at least a part of which is of the blow head 10. From the surface of the second side, it typically protrudes from the outer surface of the casing 6. Accordingly, the second air-blowing outlet 3 is advantageously easily identifiable by the user.

The means for generating the airflow F is a blower module 13 (or “motor-fan unit) that initiates the airflow F from the ambient air around the hair styling device 1, i.e. generating the airflow F. ") includes. Preferably, the blower module 13 is integrated within the hair styling device 1 itself. The hair styling device 1 is advantageously provided with an air input 14 through which ambient air can be drawn in by the blower module 13 to be blown towards the hair. The blower module 13, which typically includes at least one fan operated by an electric motor, can advantageously be arranged inside the blow head 10 or inside the handle 7, or also at the second end of the handle ( 9) can be assembled to the handle (7). However, more preferably, the blower module 13 is positioned at the second end of the handle in such a way that the blower module 13 advantageously extends the handle 7 beyond the second end 9 of the handle. It is assembled to the handle (7) at 9). Advantageously, the blow head 10 is connected to the handle 7 at a first end 8 of the handle. If the blower module 13 is thus arranged inside the handle 7 or, more preferably, assembled to the handle 7 at its second end 9, the hair styling device 1 advantageously It is arranged at least partially inside the handle 7 and comprises a formed guiding channel 15 for guiding and channeling the air flow F initiated by the blower module 13 to the blow head 10 . As in the embodiment shown in the figure, the guiding channel 15 advantageously defines a common part of the different paths followed by the air currents F inside the hair styling device 1 depending on the different blowing modes. It can be unique. However, as an alternative, several separate guiding channels could be implemented, although the simplicity of design and manufacture of the hair styling device 1 is nevertheless sacrificed. Advantageously, the means for generating an air flow F according to at least two different blowing modes thus comprise the guiding channel 15 .

The blow head 10 is removable on the handle 7 in such a way that the user can separate the blow head 10 from the handle 7, for example to clean or replace the blow head 10. It can be designed to be connected and assembled. Alternatively, as in the embodiment shown in the figures, the blow head 10 is designed to remain permanently connected to the handle 7 and is therefore not designed to be separated from the handle 7 by the user (normally when used). This further simplifies both the design and use of the hair styling device 1.

Preferably, the hair styling device 1 also comprises a heating element provided to increase the temperature of the air stream F advantageously initiated by the blower module 13 . The heating elements typically integrated into the hair styling appliance 1 are advantageously arranged in this way, intervening in the airflow F initiated by the blower module 13 . As in the embodiment shown in the figures, the heating element is advantageously located inside a guiding channel 15 arranged in the handle 7 . The heating element is typically an electrical heating element comprising an electrical heating resistor formed by an electrically conductive wire (not shown) wound around an insulating core 16. As an alternative, the heating element could be accommodated within the blow head 10, but its compactness would be compromised. Advantageously, the hair styling device (1) comprises means (17) for manual control and/or adjustment by the user of the electrical operation of the hair styling device (1), in particular the blower module (13) and/or the heating element. do. These are adjustment means, for example rocker switches, push-buttons and/or slide or thumb wheel dimmers, as in the example shown in the figure, and the user controls the hair styling device 1 to electrically activate/deactivate and change the rotational speed of the fan of the blower module 13 and thus the speed/flow rate of the air stream F blown by the hair styling device 1 and/or the heating temperature of the heating element. It can act directly on the adjustment means. These manual control/adjustment means 17 may be mounted on the handle 7 or on the blower module, for example when the blower module is assembled to the second end 9 of the handle 7, as in the example shown in the figures. It can be located at (13). The hair styling appliance 1 optionally has a cold/warm air switch (not shown) arranged on the handle 7, preferably at its first end 8, for example for switching the heating element on and off. You can include more. The hair styling device 1 , which constitutes a portable electrical appliance, is advantageously designed to be supplied with mains power, preferably via a power cord fitted at one free end with an electrical connection plug (not shown).

The means for generating the airflow F may direct the airflow F initiated by the blower module 13 to one of the first and second air-blowing outlets 2 , 3 of the hair styling device 1 and/or It also comprises an air-guiding element 18 (“air distribution element” or “air deflecting element”) for guiding and distributing it towards the other (preferably one), thus as a function of the selected blowing mode. In this way, the air-guiding member 18 arranged inside the blow head 10 and the blow head 10 are at least

Thus, the air-guiding element 18 advantageously defines or at least contributes to defining different paths of the airflow F inside the hair styling device 1 depending on the air direction configuration it takes with respect to the blow head 10 It is designed and constructed to Advantageously, the air-guiding element 18 alternately directs the airflow F coming out of the guiding channel 15 into first and second blowing outlets, depending on the air direction configuration it adopts with respect to the blow head 10. It is configured to deviate toward either 2 or 3). Preferably, the air-guiding member 18 is an air-guiding pipe (or “air-leaving pipe”) extending beyond the end of the handle 7, typically beyond the first end 8 of the handle 7. or “cup”).

According to the invention, the air-guiding element 18 has a first air-blowing outlet when the air-guiding element 18 is in said first air direction configuration (see in particular FIGS. 3 , 6 and 7 ). towards (2) and vice versa towards the second air-blowing outlet (3) when the air-guiding element (18) is in the second air direction configuration (see in particular FIGS. 5, 8 and 9), It comprises (only) one unique air-guiding outlet 19 for guiding the airflow F through said air-guiding outlet 19 . In the first air direction configuration, the air-guiding outlet 19 of the air-guiding element 18 is therefore in aerodynamic communication with the first air-blowing outlet 2, while in the second air direction configuration , the air-guiding outlet 19 of the air-guiding element 18 communicates aerodynamically with the second air-blowing outlet 3. The air-guiding element 18 is connected to the blower module 13, i.e. in aerodynamic communication with the blower module, and preferably has a unique air inlet 20 for collecting the air flow F initiated by the blower module. Also includes: If the blower module 13 is arranged within the handle 7 or at the second end 9 of the handle 7, as in the embodiment shown in the figure, the air inlet of the air-guiding element 18 ( 20 is advantageously connected, as described above, to the guiding channel 15 of the handle 7 and thus collects the air flow F initiated by the blower module 13 . Accordingly, the air-guiding element 18 advantageously extends the guiding channel 15 beyond the first end 8 of the handle 7 .

- the plurality of primary air deflectors 21 of the air-guiding outlets 19 of the air-guiding element 18 are configured such that the air-guiding element 18 is configured in the second air direction configuration ( FIGS. 8 and 9 ) are designed and configured in such a way that they are each arranged in line with a plurality of said second secondary air deflectors 23 when in position.

In other words, in the first air direction configuration, a number of primary air deflectors (21) are each aligned with one of the corresponding first secondary air deflectors (22), and in the second air direction configuration, a number of primary air deflectors (21) are each aligned with one of the corresponding first secondary air deflectors (22). Each of the two primary air deflectors 21 is aligned with one of the corresponding second secondary air deflectors 23. Advantageously, when the plurality of primary air deflectors 21 are thus arranged in line with the plurality of secondary air deflectors 22 (first air direction configuration/first blowing mode), The trailing edge of the primary air deflector 21 is thus arranged opposite the respective trailing edge of the first secondary air deflector 22 ( FIGS. 6 and 7 ). Advantageously, when the plurality of primary air deflectors 21 are thus arranged in line with each other with the plurality of second secondary air deflectors 23 (second air direction configuration/second blowing mode), The trailing edge of the primary air deflector 21 is thus arranged opposite the respective trailing edge of the first secondary air deflector 22 ( FIGS. 8 and 9 ). Advantageously, when the plurality of primary air deflectors 21 are thus arranged in line with the plurality of secondary air deflectors 22 (first air direction configuration/first blowing mode), The central extending plane Pm1 of the primary air deflector 21 is thus arranged in the same plane as the respective central extending plane Pm2 of the first secondary air deflector 22 ( FIGS. 6 and 7 ). . Advantageously, when the plurality of primary air deflectors 21 are thus arranged in line with each other with the plurality of second secondary air deflectors 23 (second air direction configuration/first blowing mode), The central extending plane Pm1 of the primary air deflector 21 is thus arranged in the same plane as the respective central extending plane Pm3 of the second secondary air deflector 23 ( FIGS. 8 and 9 ).

Thanks to the specific combination of the above-described features, the multi-mode blow hair styling device 1 according to the invention therefore has a particularly simple and efficient aerodynamic design. The embodiment of the primary air deflector 21, the first secondary air deflector 22 and the second secondary air deflector 23, and their relative selective alignment as described above, are used Whatever the air-blowing outlets 2, 3, it makes it possible to particularly optimize and homogenize the blowing of the airflow F out of the hair styling device 1 towards the hair in a particularly efficient manner. Therefore, as in the embodiment shown in the figures, the first and second air channels are inclined, in particular orthogonal, to the longitudinal extension axis A-A' of the handle 7 of the hair styling device 1. Hair styling device for ergonomic use, providing at least first and second different blowing modes, in which, depending on each blowing direction, the airflow F can be blown out of the hair styling device 1 towards the hair in a simple and efficient manner. It is possible to obtain (1). Moreover, the simplicity of the aerodynamic design of the hair styling device 1 advantageously makes it easier to manufacture the hair styling device and also contributes to its robustness and reliability.

Advantageously, with regard to design simplicity, as shown by way of example in the figures, the blow head 10 preferably:

- an additional air deflector to be arranged between the primary air deflector 21 and the first secondary air deflector 22, respectively between the primary air deflector 21 and the second secondary air deflector 23. air deflectors (“flaps” or “blades”), and/or

- to be arranged between the first secondary air deflector (22) and the first air-blowing outlet (2), respectively between the second secondary air deflector (23) and the second air-blowing outlet (3) There are no additional air deflectors (“flaps” or “blades”).

Preferably, as in the embodiment shown in the figures, on the one hand the primary air deflector 21 and on the other hand the first and second secondary air deflectors 22, 23 are stationary. do. In other words, the primary air deflector 21 remains stationary with respect to the air-guiding outlet 19 of the air-guiding element 18, whatever the air direction configuration taken by the air-guiding element 18. , the first secondary air deflector 22 does not move relative to the first air-blowing outlet 2 of the blow head 10, and the second secondary air deflector 23 moves relative to the first air-blowing outlet 2 of the blow head 10. It does not move relative to the second air-blowing outlet (3). This contributes in particular to the simplified aerodynamic design of the hair styling device 1 and the reliability of its operation.

Advantageously, with regard to aerodynamic efficiency, the hair styling device 1 is such that when the air-guiding element 18 is in the first air direction configuration, half of the primary air deflectors 21 are in the first two directions. It is designed and constructed in such a way that it is arranged in line with more than half of the primary air deflector (22). Respectively, the hair styling device (1) is advantageously configured such that when the air-guiding element (18) is in the second air direction configuration, one half of the primary air deflector (21) is in the second secondary air deflector (23). ) are designed and constructed in such a way that they are arranged in a row with more than half of the Even more advantageously, as in the embodiment shown in the figures, the hair styling device 1:

- in said first air direction configuration, a number of primary air deflectors (21) equal to at least n1-1 are arranged in line with a number (n2) of first secondary air deflectors (22), while

- in said second air direction configuration, a number of primary air deflectors (21) equal to at least n1-1 are arranged in line with a number (n3-1) of second secondary air deflectors (23). It is designed and structured in a way.

In order to mechanically reinforce the primary air deflector 21 , the air-guiding elements 18 are preferably arranged in pairs on the one hand and between air-guiding outlets 19 on the other (FIG. 13 ) and a primary spacer 24 that mechanically connects the primary air deflector 21 to the peripheral edge of the primary air deflector 21. Even more preferably, the primary spacer 21 simplifies the design of the air-guiding element 18 and eliminates flow disturbances of the air current F that can be created by the presence of the primary spacer 24. In this way, along at least one line 24A of the primary spacer 24, as in the example shown in the figure, two lines of the primary spacer are possibly advantageously parallel to each other. They are arranged in a row along (24A, 24B). Similarly, in order to mechanically reinforce the first secondary air deflectors 22, the blow heads 10 are advantageously provided in pairs mechanically connecting said first secondary air deflectors 22 to each other. It may include a first secondary spacer (25). Preferably, the first secondary spacer 25 then extends, possibly advantageously, along at least one line 25A of the first secondary spacer 25, as in the example shown in the figures. They are arranged in a row along two lines 25A, 25B of the first secondary spacers 25 that are parallel to each other. Conversely, in order to mechanically reinforce the second secondary air deflector 23, the blow head 10 advantageously has a second device which mechanically connects the second secondary air deflector 23 between each other. May include secondary spacers. Preferably, the second secondary spacers are then arranged in line along at least one line of spacers, possibly along two lines of second secondary spacers.

Even more preferably, the line(s) 24A; 24B or the respective line(s) 24A; 24B of the primary spacer 24 are in said first air direction configuration of the air-guiding member 18. , are aligned coplanarly in the alignment plane Pa1 with the line(s) 25A, 25B of the corresponding first secondary spacer 25 or one of them. Conversely, the line(s) 24A, 24B of the primary spacer 24 or the respective line(s) 24A, 24B are advantageously in said second air direction configuration of the air-guiding element 18 , may be arranged coplanarly in line with the line(s) of corresponding second secondary spacers or in an alignment plane with one of them. This alignment of the lines of spacers advantageously serves to limit flow disturbances of the air current F that can be created by the presence of said spacers. In general, this embodiment of the primary spacer 24, the first secondary spacer 25 and the second secondary spacer advantageously comprises a primary air deflector 21 and the first and second secondary air deflectors. The air-guiding outlet 19, the first air-blowing outlet, in this way maintains the good mechanical robustness of the deflectors 22, 23, while providing them with a high useful airflow cross-section, usually in the preferred range mentioned below. (2) and the size of the second air-blowing outlet (3).

In order to provide optimal blowing of the air flow F towards the hair, especially in view of the air flow rate, the first air-blowing outlet 2 and the second air-blowing outlet 3 each preferably have an area of between 1 cm 2 and 3. Each has a minimum total effective cross-sectional area of 20 cm2, more preferably 8 cm2 to 15 cm2. Even more preferably, the first air-blowing outlet (2) and the second air-blowing outlet (3) have a minimum total effective cross-sectional area of the same value. The air inlet 20 of the air-guiding element 18 then preferably has an effective cross-sectional area (or “air inlet effective cross-sectional area”) of between 1 cm 2 and 20 cm 2, more preferably between 8 cm 2 and 15 cm 2 . The air-guiding outlet 19 of the air-guiding element 18 preferably has an effective cross-sectional area (or “air outlet effective cross-sectional area”) of preferably between 1 cm 2 and 20 cm 2, more preferably between 8 cm 2 and 15 cm 2. .

Preferably, as described above, the first air-blowing outlet 2 extends longitudinally along the average extension axis B-B' of the blow head 10. Conversely, as also described above, the second air-blowing outlet 3 preferably extends longitudinally along the average extension axis B-B' of the blow head 10, preferably with a unique It has an air-blowing opening. This advantageously results in rapid and efficient processing of the hair in a limited number of passages of the hair styling device 1 for said hair (and thus independently of the nature of the blowing mode in which the hair styling device 1 is designed to operate). makes possible. Even more advantageously, the blow head 10 connects the first air-blowing outlet 2 and the mechanical hair-engaging element 11, as considered above and in the embodiment shown in the figures. When having a first side, the first air-blowing outlet 2 preferably has mechanical hair-engaging elements 11 extending respectively along the average extension axis B-B' of the blow head 10. extends longitudinally along the average extension axis B-B' of the blow head 10 over a length that is at least half, more preferably at least two-thirds, of its respective length.

In the specific case of this longitudinally extending configuration of the first and second air-blowing outlets 2, 3, the air-guiding element 18 preferably has an air inlet 20 of the air-guiding element 18. A side wall 26 extending along the longitudinal extension axis E-E' of the air-guiding element 18 between the first end 27 defining it and the opposing closed second end 28 (airtight). ) (Confidential). Advantageously, the air-guiding outlet 19 of the air-guiding element is formed through the side wall 26 of the air-guiding element 18 and along the longitudinal extension axis E-E' of the air-guiding element. extending longitudinally (but not necessarily parallel to the axis of longitudinal extension (E-E')). Accordingly, as described above, the air-guiding outlet 19 is advantageously such that the air flow F flowing through the air inlet 20 flows along it into said air input 20 (Figure 6 and which flows out through the air-guiding outlet 19 along a mean outflow direction intersecting (or at least arranged to be inclined towards) the mean inflow direction into the air-guiding element 18 via FIG. 8 ). It is designed and structured in a way. As shown by way of example in the figures, the side wall 26 advantageously forms a hollow internal shape whose cross-sectional area decreases from the first end 27 towards the second end 28 of the side wall 26. . The air-guiding element 18 thus advantageously forms an air-guiding pipe formed by said side wall 26 , which has a generally truncated conical internal shape. In other words, the air-guiding element 18 advantageously comprises a hollow tube of generally frustoconical internal shape formed by said side wall 26 . The hollow tube typically has an axis of revolution advantageously defined by or parallel to the longitudinally extending axis E-E' of the air-guiding element 18 . The longitudinal extension axis E-E' of the first air-blowing outlet 18 is advantageously merged with the average extension axis B-B' of the blow head 10. The respective longitudinal extension axes B-B', E-E' of the blow head 10 and the air-guiding element 18 advantageously have an average longitudinal extension axis A-A' of the handle 7. ) is on the same line. The first end 27 of the side wall 26 thus forms a large base of generally truncated conical internal shape, through which the airflow F enters the air-guiding element 18 . This hollow internal shape, the cross-sectional area of which decreases from the first end 27 of the side wall 26 towards the second end 28 , advantageously profiles the air flow F circulating inside the air-guiding element 18 homogenizes and thus makes it possible to further improve the aerodynamic performance of the hair styling device 1.

Even more advantageously, the air-guiding outlet 19 of the air-guiding outlet 18 is located at the second end of the side wall 26 of the air-guiding element 18, as shown by way of example in FIG. 13 in particular. It has an effective cross-sectional area that decreases towards (28). This advantageously homogenizes the profile of the airflow F exiting the air-guiding element 18 via the air-guiding outlet 19 and thus further improves the aerodynamic performance of the hair styling device 1. Contribute.

The blow head 10 advantageously has a first air-blowing outlet of the blow head 10 when the air-guiding element 18 assumes the first air direction configuration, as in the embodiment shown in the figures. 2) and a first channeling portion 29 provided to ensure aerodynamic communication of the air-guiding outlet 19 of the air-guiding member 18, and the air-guiding member 18 of the blow head 10. It comprises a second channeling portion (30) provided to ensure aerodynamic communication of the air-guiding outlet (19) with the second air-guiding outlet (3) when taking the two-air direction configuration. As shown in the figure, the blow head 10 forms for this purpose at least in part the first and second channeling portions 29, 30 and thus forms a “two-way” internal channeling system (or “two-way distributor”). ) may also include an internal channeling system 31 constituting the. The internal channeling system 31 is advantageously fixed and motionless relative to the first and second air-blowing outlets 2, 3 of the blow head. Accordingly, the air-guiding element 18 and the internal channeling system 31 of the blow head 10 are movably mounted relative to each other between the first and second air direction configurations. Accordingly, when the air-guiding element 18 assumes the first air direction configuration (in particular FIGS. 3 , 6 and 7 ), the air-guiding outlet 19 of the air-guiding element 18 has an internal channeling system. It communicates aerodynamically with the first channeling part 29 of 31 and thus with the first air-blowing outlet 2 . On the other hand, the air-guiding element 18 (eg its side wall 26 ) then closes the second channeling portion 30 of the internal channeling system 31 . Conversely, when the air-guiding element 18 assumes the second air direction configuration (in particular FIGS. 5, 8 and 9), the air-guiding outlet 19 of the air-guiding element 18 It communicates aerodynamically with the channeling portion 30 and thus with the second air-blowing outlet 3 . The air-guiding element 18 (eg its side wall 26 ) then closes the first channeling portion 29 of the internal channeling system 31 .

Preferably, the air-guiding element 18 is arranged at least partially within the internal channeling system 31 , as can be seen by way of example in the figures, which depends on the size of the blow head 10 and, more generally, on the hair This contributes to reducing the size of the styling device (1). Advantageously, the first and second secondary air deflectors 22 , 23 included in the blow head 10 are supported by an internal channeling system 31 ( FIGS. 15 to 17 ). Advantageously, as in the embodiment shown in the figures, the first channeling portion 29 has an effective airflow cross-section that continuously decreases towards the first air-blowing outlet 2 . Conversely, the second channeling portion 30 advantageously has an effective airflow cross-section that continuously decreases towards the second air-blowing outlet 3 . This advantageously promotes the circulation of the air flow F towards the first air-blowing outlet 2 (FIG. 18) and, respectively, towards the second air-blowing outlet 3 (FIG. 19) and thus the blow head. (10) contributes to reducing the risk of internal increased air pressure and air blockage, as well as the risk of (possibly hot) air leakage into other parts of the blow head (10).

In particular, depending on the shape and configuration of the air-guiding element 18, various kinematics can be considered for the air-guiding element 18 and the blow head. However, preferably, in view of the simplicity of design and use of the hair styling device 1, the blow head 10 is fixedly connected to the handle 7 of the hair styling device 1, and the air-guiding element ( 18) is movably mounted relative to the blow head 10 and the handle 7 between the first and second air direction configurations. In particular, in order to simplify the design of the hair styling device 1 and improve its miniaturization, the air-guiding element 18 and the blow head 10 are preferably positioned at least between the first and second air direction configurations. They are mounted to rotate and pivot relative to each other about the axis of rotation (D-D'). Preferably, the axis of rotation (D-D') is an air-guiding element (18) which is itself advantageously merged (colinear) with the average extension axis (BB') of the blow head (10). is merged with (collinear with) the longitudinal extension axis (E-E'), or is at least parallel. As an alternative (not shown), the air-guiding element 18 is fixedly connected to the handle 7 and the blow head 10 is then connected to the air-guiding element 18 and the blow head 10. It is mounted to rotate around the rotation axis (D-D'). As another alternative implemented in the embodiment shown in the figures, the blow head 10 is fixedly connected to the handle 7 and the air-guiding element 18 is connected to the blow head 10 and the handle 7. , is mounted for rotation about the rotation axis (D-D'). According to the above, this second alternative is advantageous in that it contributes to simplifying the design and use of the hair styling device 1. In this case, the above-described internal channeling system 31 is thus advantageously itself fixedly connected to the handle 7 of the hair styling device 1, and the air-guiding element 18 is advantageously connected to said first and Between the second air direction configurations, it is arranged for rotation about the axis of rotation D-D' within the internal channeling system 31.

In order to make the hair styling device 1 even more practical and intuitive to use, the first and second air-blowing outlets 2, 3 preferably have an average direction of extension of the hair styling device 1 (or if Accordingly, one of the average extension directions of the hair styling device 1) is arranged opposite to each other on both sides of the inscribed plane P1. The average direction of extension thus corresponds here to the average direction of extension of the part of the hair styling device 1 with the first and second air-blowing outlets 2, 3. Accordingly, the average direction of extension of the hair styling device 1 preferably corresponds to the average extension axis B-B' of the blow head 10. Accordingly, the first and second air-blowing outlets 2, 3 are preferably arranged opposite to each other on both sides of the plane P1 in which the average extension axis B-B' is inscribed. In this way, the first and second air-blowing outlets 2 , 3 are thus advantageously positioned when the user is looking straight at the first air-blowing outlet 2 and the second air-blowing outlet 3 respectively. It is not simultaneously visible to the user. The user can, in the preferred case, typically have the blow head 10 fixedly connected to the handle 7 and the air-guiding element 18 mounted for rotation relative to the blow head 10 and the handle 7. The hair styling device (1) can be adjusted by simply rotating the handle (7) of the hair styling device (1) by 180° to direct the corresponding one of the air-blowing outlets (2, 3) towards the hair to be treated. It can be easily used alternately depending on the first blowing mode or the second blowing mode.

Advantageously, the hair styling device 1 also comprises a control system for controlling the respective switching of the hair styling device 1 from one of the first and second air direction configurations to the other. Accordingly, the control system allows the user to alternately select any of the blowing modes, i.e. from one of the blowing modes to another of the blowing modes, for example from a first blowing mode to a second blowing mode, and vice versa. It is provided to control the transition of the hair styling device 1 from the second blowing mode to the first blowing mode. In this respect, as in the embodiment shown in the figures, the control system advantageously controls the respective transition of the air-guiding element 18 from one of the above-described first and second air direction configurations to the other. It is connected to the air-guiding member 18 to do this. By acting on the control system, the user can thus alternately select one or the other of the blowing modes of the hair styling device 1 among said at least two different blowing modes. Accordingly, the user can advantageously choose whether the air stream F will be blown from the hair styling device 1 via either the first and second air-blowing outlets 2, 3, and thus the hair styling device ( 1) You can select the operation mode. The control system advantageously comprises means ( 17 ) is separate from Therefore, before starting the blower module 13 of the hair styling appliance 1, it is advantageously possible for the user to select one of the blowing modes, while the other of the blowing modes is selected. The control system is advantageously integrated into the blow head 10 and is preferably positioned along the average extension axis B-B' of the blow head. Preferably, at least one part of the elements of the control system forms or at least contributes to form the upper part (free end) of the blow head 10 . This enables easy and intuitive activation of the control system by the user.

Advantageously, the control system for changing the blowing modes of the hair styling device 1 allows the user to act on the control system and thus move to alternately manually select one or the other of the blowing modes. Possible manual control elements include, for example, buttons 32 and thumbwheels. “Moveable” means herein that the manual control member is advantageously predefined (hair styling device (1 ) is advantageously understood to be possible to develop between at least two positions and/or spatial orientations. Preferably, as shown by way of example in the figures, the manual control member is arranged on the blow head 10, i.e. supported by (or belonging to) the blow head 10 and not by the handle 7. . This makes it possible to limit the risk of unintentional handling of the manual control unit by the user's hand holding the handle 7. Also preferably, the manual control element is arranged at such a distance from the handle 7 that the fingers of the user's hand holding the handle 7 cannot reach it. Manual control elements that are inaccessible to the fingers of the user's hand holding the handle 7 are, however, advantageously kept accessible by the fingers of the other user's hand. Even more preferably, as also shown by way of example in the figures, the manual control member is arranged substantially along an axis parallel to or merging with the average extension axis B-B' of the blow head 10, such that the blow It becomes accessible to the user from above the head 10.

Advantageously, as shown in the figure, the control system of the hair styling device 1 is a “push-push” button control mechanism 32 (or a “push-push kinematic control mechanism”) and thus the blowing mode. Controls the respective switching of the hair styling device 1 from one of the blowing modes to the other of the blowing modes. A control system, for example designed to be operated manually by a user, may thus be configured to direct the hair styling device 1 from one of the blowing modes to the other of the blowing modes, or at least from one of the blowing modes to the other of the blowing modes. It is designed and configured to mechanically translate each push applied by a user (typically using the user's finger) on a button 32 of the control system into a transition. The button 32 of the control system then advantageously forms the manual control element described above. Accordingly, as in the embodiment shown in the figures, the push-push button control mechanism 32 advantageously switches the air-guiding element 18 from one of the first and second air direction configurations described above to the other. It is connected to an air-guiding member 18 to control the respective transitions.

Thanks to this push-push button control mechanism 32, the reproduction of a simple push action by the user on the button 32 of the control mechanism changes the respective blowing mode of the hair styling device 1, each time following the same push direction. The use of the hair styling device 1 is therefore particularly simple and intuitive. Accordingly, each push applied by the user on the button 32 of the control mechanism will cause the hair styling device 1 to return to said initial blowing mode after the control mechanism has been operated successively the number of times it has a different blowing mode. and controlling periodic switching of the hair styling device 1 from a given initial blowing mode to the next blowing mode, etc. In the hypothesis that the means for generating the airflow F of the hair styling device 1 are designed to generate the airflow F according to only two different blowing modes, each applied by the user on the button 32 The push thus moves from the first operating mode of the hair styling device 1 (first blowing mode) to the second operating mode of the hair styling device 1 (second blowing mode) and then to the first operating mode of the hair styling device 1 (second blowing mode). Controls alternate switching from the operation mode to the second operation mode, etc.

Advantageously, the push-push button control mechanism 32 is designed and configured to control the respective switching of the hair styling device 1 from one of the blowing modes to the other of the blowing modes in a purely mechanical manner. Accordingly, the control mechanism is configured to switch the hair styling appliance 1 from one of the blowing modes to the other of the blowing modes, or at least from one of the blowing modes to the other of the blowing modes, by pressing the button 32 of the control system by the user. It is designed and configured to mechanically translate each push applied on the device (typically using the user's finger). Accordingly, the push-push button control mechanism 32 advantageously has no electrical or electromechanical components, making its design particularly simple, economical and reliable. Accordingly, as in the embodiment shown in the figures, the button 32 of the push-push button control mechanism advantageously operates under the influence of a push applied (by the user) to the button 32. mechanically connected to the air-guiding element 18 to mechanically convert each movement of the button 32 into a movement of the air-guiding element 18 from one of the first and second air direction configurations to the other. do. This will thus advantageously establish an electromechanical connection between the button of the control mechanism and the pneumatic-guiding element, i.e. the mechanical push applied by the user on the button is connected to the electrical actuator to be connected to the pneumatic-guiding element 18 . It is not an electromechanical push-push button control mechanism that will be designed to convert to electrical control. An embodiment of this purely mechanical control mechanism advantageously allows the user to control the hair styling device 1 even while the hair styling device 1 is not switched on (i.e. when the hair styling device 1 is switched off or even unplugged). Allows you to change the blowing mode. Accordingly, the safety of use of the hair styling device 1 is improved, in that the risk of immediate air blowing in a direction unexpected by the user, for example towards his/her face, is thus limited. Nevertheless, the hair styling device 1 remains easy to use because the user maintains the possibility of changing the blowing mode of the hair styling device 1 even while the hair styling device is in operation. Moreover, the implementation of purely mechanical control of the blowing mode change, rather than electromechanical control, tends to improve the operational reliability of the hair styling device 1 and to reduce its manufacturing and use costs.

According to an alternative (not shown), the button of the push-push button control mechanism is a bistable button. Typically, the control mechanism then deploys the button from a first stable position (referred to as the release position) to a second unstable position (referred to as the unstable push position) under the influence of a first push applied by the user, When the first push applied by is stopped, under the influence of the elastic return member, it automatically returns to a third stable position (referred to as a stable pressing position) intermediate between the first stable position and the second unstable position. It is designed and structured in such a way that it is possible. The button is then kept temporarily locked in the stable pressed position corresponding to one of the blowing modes of the hair styling device 1 . Conversely, the control mechanism then moves the button from the third stable pressed position towards the second unstable pressed position under the influence of a second push applied by the user, which is continuous with said first push and thus enables the button to be unlocked. It is designed and constructed in such a way that it is possible to deploy and then, when the second push applied by the user is stopped, return towards the first stable release position under the influence of the elastic return element. For example, such a bistable push-push button control mechanism can implement so-called “cardioid” mechanism kinematics.

According to a preferred alternative implemented in the embodiment shown in the figures, the button 32 of the push-push button control mechanism 32 is a monostable button. Accordingly, the control mechanism preferably causes button 32 to shift from a first stable position (also referred to as a release position or “non-pressed position” or also “rest position”) to a second unstable position under the influence of a push authorized by a user. designed in such a way that it is deployed to a position (referred to as the pressed position) and is then configured to automatically return from the pressed position to the released position, under the influence of the elastic return member 33, when the push applied by the user is stopped. becomes and is composed. This “monostability” alternative is more advantageous than the “bistable” alternative described above, because the button 32 systematically returns to the released position, remaining equally accessible to the user whatever the selected blowing mode. Because it becomes. Moreover, these "monostable" alternatives are simpler in design and more robust in use.

Accordingly, whether a “bi-stable” or “monostable” alternative is considered, the push-push button control mechanism 32 advantageously includes at least one device that automatically guides the button 32 from the pressed position back to the released position. It includes an elastic return member (33). Preferably, the elastic return element 33 is a spring, in particular a tension, compression or flexion (leaf) spring.

Button 32 of the push-push button control mechanism 32 is typically connected to a user (e.g., his/her device) when he/she applies a push on the button 32 to control a blowing mode change. It has a contact portion 34 or an interaction portion intended to be in direct contact (with the finger). Accordingly, the contact portion 34 is oriented towards the outside of the hair styling device 1 and forms that part of the outer surface of the button 32 that is visible and accessible to the user from outside the hair styling device 1 . Advantageously, the contact portion 34 forms a free upper part of the button 32 opposite a lower end of the button 32 which is (permanently) arranged inside the hair styling device 1 . As in the embodiment shown in the figures, the control mechanism is such that when button 32 is in the released position, the contact portion 34 of button 32 is preferably (completely) connected to the casing of hair styling device 1. (6) Designed and constructed in such a way that they are arranged externally. Accordingly, in the release position and thus in the absence of an applied push on the button 32 the button is advantageously pushed away from the outer surface of the hair styling device 1, typically from the outer surface of the casing 6 of the hair styling device. It protrudes. This allows easier visual and/or tactile identification of the button 32, access to the button 32, and handling of the button by the user. Moreover, this may advantageously limit the risk of contact between the user and the external surface of the hair styling device 1, which can possibly be hot, and thus may contribute to limiting the risk of burns.

In either case, the control mechanism is preferably such that the button 32 deploys towards its pressed position under the influence of a push applied by the user to switch the hair styling device 1 from one blowing mode to another. in such a way that the contact portion 34 of the button 32 is arranged below the outer surface (or at least the outer geometric envelope) of the casing 6 of the hair styling device 1 (i.e. the button 32 The hair styling device 1 is preferably designed and constructed in such a way that it fully retracts and retracts within the hair styling device 1. Accordingly, the risk of unintentional changing of the blowing mode due to interaction of the button 32 with the user or surrounding elements is advantageously limited. As in the embodiment shown in the figures, the contact portion 34 of the button 32 is preferably provided with a recessed area, ie an area with a recess directed towards the outside of the hair styling device 1 . The presence of this recessed area, preferably located in the center of the contact portion 34, advantageously guides the positioning of the fingertip end, especially the fingertip pulp portion, on the contact portion 34 of the button 32. This helps to keep the finger positioned in this way to efficiently apply a push effort on the button 32 to control blowing mode changes, in particular without having to make visual contact with the button 32.

According to an alternative (not shown), the control mechanism is configured to convert each push applied by the user on a button of the control mechanism into a switch of the hair styling device 1 from one of the blowing modes to another of the blowing modes. It can be designed and constructed. In this case, a single push applied by the user on the button of the control mechanism makes it possible to switch the hair styling device 1 from one of the blowing modes to another of the blowing modes. Once the hair styling device 1 has effected this different blowing mode, the user can then stop applying his/her push effort on the button. According to another, more preferred alternative implemented in the embodiment shown in the figures, the push-push button control mechanism 32 is such that each push applied by the user on the button 32 of the control mechanism causes one of the blowing modes. Switching of the hair styling device 1 from one of the blowing modes, i.e. to a transition, and then, when the push authorized by the user stops, the button 32 towards said stable release position (non-pressed position). ) is designed and configured to automatically complete the transition of the hair styling device 1 to another one of the blowing modes under the influence of the automatic return of the blowing mode. In other words, the blowing mode change is then initiated only by pressure applied by the user on the button 32 and then automatically terminated by the control mechanism. This makes changing the blowing mode particularly easier, more intuitive and faster for the user.

As in the embodiment shown in the figures, the air-guiding element 18 is advantageously mounted for rotation, pivoting about said axis of rotation D-D', at least between the first and second air direction configurations. When done, the control system, for example the push-push button control mechanism 32 described above, then controls the rotation of the air-guiding element 18 according to a predetermined rotation angle about the axis of rotation D-D'. thereby controlling the switching of the air-guiding element 18 from one of the first and second air direction configurations to the other. Even more preferably, the air-guiding element 18 is mounted for rotation relative to the handle 7 of the hair styling device 1, and the axis of rotation D-D' of the air-guiding element 18 is preferably It is preferably parallel to, or even more preferably merges with, the longitudinal extension axis A-A' of the handle 7.

As described above, ensuring a mechanical connection between the button 32 of the push-push button control mechanism and the pneumatic-guiding member 18, thereby reducing the mechanical push effort applied by the user on the button 32 to the pneumatic-guiding member 18. For transmission to the guiding element, the control mechanism preferably has a rotary engagement part ( 35). The button 32 is advantageously configured such that each push applied on the button 32 causes a rotation of the rotatable engaging portion 35 about the axis of rotation and an air-guiding member along that axis D-D'. 18) is fastened to at least one pin 36 (or roller) forming a follower that cooperates with the cam in this way to cause a corresponding rotation of the cam. Preferably, as in the embodiment shown in the figures, the button 32 of the push-push button control mechanism 32 is mounted for straight translation, even more preferably the rest of the hair styling device 1. Whether, in particular, the handle 7 is equipped for purely straight translation along the direction of translation C-C' between the non-pressed position (or release position) and the pressed position, as described above. . Accordingly, the movement of button 32 under the influence of a push applied by the user is purely linear translation, i.e. according to a straight glide connection, and has the same average direction as the pushing effort applied by the user. Therefore, whatever the position and orientation of the button 32 with respect to the user when the hair styling device 1 is used, the handling of the button 32 is particularly easy and intuitive for the user. Alternatively, although less advantageous from the point of view of design simplicity and size, as well as from the point of view of ergonomics, the button can be mounted for tilting, for example by rotating or pivoting, and the contact part of the button can be pushed by the user. It can be formed and configured in such a way that it follows a curved arc-shaped trajectory under the influence of . Even more preferably, the button 32 is arranged relative to the rotationally engaging portion 35 in such a way that the straight translational direction (C-C') of the button 32 merges with the rotational axis of the rotationally engaging portion 35. do. Accordingly, each push applied by the user on the button 32, according to a particularly simple and compact design due to the advantageous absence of the intermediate part between the button 32 and the rotary engagement part 35, This causes a linear translation of the button 32 and, preferably directly, a rotation of the rotationally engaging portion 35 about the direction of translation C-C' of the button 32. Alternatively, the direction of linear translation of the button 32 is provided parallel to and offset with respect to the axis of rotation of the rotary engagement portion 35, or also inclined or perpendicular to the axis of rotation of the rotary engagement portion 35. This can be provided, but at the expense of simplicity and miniaturization of the design of the control mechanism. Advantageously, the rotationally engaging portion 35 is rotationally locked relative to the air-guiding member 18 , and the rotational axis of the rotationally engaging portion 35 is aligned with the respective rotational axes D-D of the air-guiding member 18. ') and merged with. Accordingly, each movement of the button 32 under the influence of a push applied by the user, by the predetermined rotation angle, causes the joint of the air-guiding member 18 and the rotational engagement portion 35 about the common axis of rotation to move by the predetermined rotation angle. causes rotation. This contributes to the simplicity and reliability of the design and operation of the hair styling device 1. For example, as shown in the figure, the rotational engagement portion 35 and the air-guiding member 18 are assembled together by shape complementarity and by screw connection or by clip fastening/snap connection or gluing. can be fixed to each other. As an alternative, the rotationally engaging portion 35 and the air-guiding element 18 could possibly together form a monolithic part.

Preferably, as in the embodiment shown in the figures, the rotary engagement part 35 more specifically forms a grooved drum cam. Accordingly, the rotationally engaging portion 35 comprises at least a revolving cylindrical portion, which forms a cam track bounded by two opposing side walls of the groove 37 and a follower pin 36 fixed to the button 32. ) A groove 37 designed to be moved is provided. Accordingly, the pin 36 is captured in the groove 37 , which serves to provide a reliable mechanical connection between the button 32 and the rotary engagement part 35 . Even more preferably, the groove 37 is peripheral, extending along the entire circumference of the revolved cylindrical part and closed to itself. Accordingly, the rotation of the rotary engagement part 35 about its rotation axis can be performed in the same direction of rotation in each command for changing the air direction configuration, and therefore the blowing mode.

For example, in the embodiment shown in the figures, button 32 is configured for (pure) straight-line translation along its translation (gliding connection) direction C-C', which merges with the axis of rotation of straight-line translation 35. It is installed. Preferably, the straight translational direction C-C' is parallel to or merges with the mean extension axis B-B' of the blow head 10, which itself is advantageously parallel or merged with the axis of rotation (D-D') of the air-guiding element (18), which axis of rotation (D-D') is advantageously the average longitudinal extension axis (A-A') of the handle (7) parallel to or merged with This is thus advantageous, especially when the four aforesaid axes and directions (A-A', B-B', C-C', D-D') are merged, resulting in a particularly simple construction and a particularly compact hair styling device. causes (1). The button 32 advantageously has at least a partial overlap of said cylindrical parts and is circular in revolution around a straight translational direction C-C', which is arranged parallel to the revolution cylindrical part of the rotationally engaging part 35. It includes a cross-sectional side skirt portion 38. Button 32 is not connected to a single pin 36, for even greater reliability of the mechanical connection between button 32 and rotary engagement part 35, but is positioned in the straight translational direction (C-C'). It is connected to two follower pins 36 arranged on the sides. The free end portion of each pin 36 is here received in a groove 37 of the grooved drum cam formed by the rotary engagement part 35 . blocking the rotation of the button 32 relative to the rest of the hair styling device 1, in particular relative to its handle 7 and guiding the translation of the button 32 along the straight translation direction C-C' For this purpose, a portion of each pin 36 is positioned within a respective rectangular guide hole 39 formed in a portion that is immovable relative to the handle 7 (e.g., a portion fixed to the internal channeling system 31 described above). It is accepted. To facilitate assembly of the hair styling device 1, once the button 32 has been assembled overlapping the pivoting cylindrical portion of the rotationally engaging portion 35, the portion of the bar forming the follower pin 36 In this way, the pin 36 extends radially on the inside of the button 32, while the opposing portion of the bar extends radially on the outside of the button 32 and is captured within one of the rectangular guide holes 39. Each of these may be formed by a cylindrical bar press-fitted into a hole formed in the wall of the side skirt portion 38 of the button 32.

Advantageously, the push-push button control mechanism 32 comprises an elastic return element 33, for example a compression spring, as already described above. The resilient return member 33 is constructed and arranged to automatically guide the button 32 back to its stable released position (non-depressed position) when the push applied by the user on the button 32 is stopped. As shown in the figure, the compression spring may be arranged between the inner surface of the button 32 and the surface of the rotationally engaging portion 35. Advantageously, the cam formed by the rotationally engaging portion 35:

- movement of the button 32 of the push-push button control mechanism under the influence of a push applied by the user on the button 32, for only one first part of said predetermined rotation angle,

- Then, when the push applied by the user stops, by means of a movement of the button 32 in the opposite direction under the combined influence of the elastic return element 33 and the cam, for the remainder of said predetermined rotation angle,

Said predetermined method, which allows the hair styling device 1 to be switched from one blowing mode to another by means of a corresponding switch of the air-guiding element 18 from one air direction configuration to another air direction configuration. It is adapted and configured in such a way that rotation of the air-guiding element 18 by the angle of rotation is carried out.

Therefore, as described above as a preferred alternative, the blowing mode change is initiated only by a push authorized by the user on the button 32, and the blowing mode change is initiated only after the user stops pushing the button 32 of the control mechanism. , it is automatically terminated by the control mechanism. Accordingly, the user advantageously has to provide only a fraction of the effort required to rotate the air-guiding element 18 by a predetermined rotation angle to switch from one of its air direction configurations to the other. As described above, this makes changing the blowing mode particularly easier, more intuitive and faster for the user. Even more preferably, the cam moves the button 32 of the control mechanism under the influence of a push applied on the button 32 for no more than 50% of said predetermined rotation angle (i.e. up to 50%). (for example only 30%, 40% or 50%) and then, when the applied push is stopped, the button 32 in the opposite direction, under the combined influence of the elastic return element 33 and the cam. movement of the air-guiding member 18 by the predetermined rotation angle for the remainder of the predetermined rotation angle (i.e. for at least 50%, for example 50%, 60% or 70%). It is formed and constructed in such a way that rotation is performed.

This feature is obtained, for example, by modulating the profile of the cam track defined by the grooves 37 of the grooved drum cam described above to form at least two successive cam track portions forming slopes of opposite slope. may occur, and its movement by the follower pin 36 causes rotation of the air-guiding member 18 by a predetermined rotation angle as follows: First, when the user applies pressure on the button 32 to guide the button from the released position to the pressed position, the pin 36 slides against one of the side walls of the groove 37 forming the first slope, thereby It moves along the first cam track portion, thereby causing rotation of the rotationally engaging portion 35 by a first rotation angle. Then, when the user stops pushing the button 32, the resilient return member 33 automatically guides the button 32 back to its released position (non-pressed position), and the pin 36 then At this time, the pin 36 moves along the second cam track portion by sliding against another one of the side walls of the groove 37 forming the second inclined portion with an inclination opposite to that of the first inclined portion, and the pin 36 moves along the elastic return member 33. ) is applied to the second inclined portion under the influence of ), thus forcing the rotation of the rotationally engaging portion 35 in the same direction by the second rotation angle. The inclination of the first ramp is equal to or greater than the inclination of the second ramp, in such a way that the first rotation angle is therefore smaller than the second rotation angle and the sum of the first and second rotation angles corresponds to a predetermined rotation angle. It is chosen to be larger and steeper. Accordingly, the first rotation angle corresponds to a movement initiated by a user push, while the second rotation angle corresponds to the automatic complementary movement described above.

For example, as in the embodiment shown in the figures, the transition of the air-guiding element 18 from one of the first and second air direction configurations to the other causes the air-guiding element 18 to rotate its axis of rotation by a predetermined rotation angle of 180°. This is accomplished by rotation of the air-guiding member 18 about (D-D'). Accordingly, by rotating 360° about its axis of rotation D-D' under the influence of two successive pushes applied on button 32, air-guiding element 18 advantageously changes its angular configuration into 2 By changing the number of times, the first and second air direction configurations can be alternated. The grooved drum cam is then advantageously provided with a rotation of the air-guiding element 18 by the predetermined rotation angle from its (stable) release position under the influence of the pressure applied by the user to the button 32. a purely linear translation of the button 32 to the (unstable) pressed position for only 90° (the first rotation angle) (i.e. 50%), followed by a push authorized by the user for the remaining 90°. When stopped, by a purely linear translational movement in the opposite direction of the button 32 from its (unstable) pressed position to its (stable) released position, under the combined effect of the elastic return element 33 and the grooved drum cam. It can be formed and structured in this way.

Preferably, the hair styling device 1 further comprises an indicator system comprising a visual selection indicator, for providing the user visual information as to which of the blowing modes has been selected. The implementation of such an indicator system is even more interesting in the preferred case shown by way of example in the drawing, wherein the button 32 of the control mechanism is a monostable button, i.e. always in the same rest position whatever the operating mode of the device 1 is. This is the button that occupies. As in the embodiment shown in the figures, the indicator system may be a mechanical indicator system, ie an indicator system whose state changes are controlled in a purely mechanical manner to reflect the selected blowing mode. In this respect, the indicator system preferably has at least one opening 40A formed on the side of the button 32 of the control mechanism (through-opening potentially closed by a transparent element) and at least partially inside the button 32. and which, depending on which of the blowing modes is selected, is visible through the opening 40A or not, or is visible in a different way (from the outside of the device 1). It includes a display portion 41 that is movably mounted relative to 40A). Advantageously, the side of the button 32 on which the opening 40A is formed is the side that is visible to the user, whatever the blowing mode selected. Even more advantageously, as in the embodiment shown in the figures, this side of the button 32 has its previously described contact portion 34. Even more preferably, the indicator system comprises at least two (separate) openings 40A, 40B arranged on the side of the button 32, wherein the indicator portion 41 is configured to indicate which of the blowing modes is selected. movable relative to the button 32 in this way, alternatively visible or not visible, or visible in a different way (from outside the device 1), depending on whether it is visible through either of the openings 40A, 40B. It is installed. More generally, the indicator system may advantageously comprise the same number of openings 40A, 40B as the hair styling device 1 has different blowing modes. Openings 40A, 40B may have the same shape (FIG. 22), or may have a different, unique shape.

For example, as in the embodiment shown in the figures, the marking part 41 can be mechanically connected to the air-guiding member 18 via a rotatable coupling part 35 , In this way, where the rotation causes a co-rotation of the display portion 41, the rotation can be fixed relative to the rotationally engaging portion. The display portion 41 may advantageously comprise at least one arm or disk 42 extending radially with respect to the axis of rotation of the display portion 41 , the upper side of which has an area 43 colored. located (or otherwise marked) (FIG. 22) is directed towards the side of the button 32 with openings 40A, 40B. The colored area 43 then forms the visual selection indicator. The rotationally engaging portion 35 is advantageously blocked from rotation relative to the air-guiding element 18 , and the rotational axis of the rotationally engaging portion 35 corresponds to the respective rotational axes D-D' of the air-guiding element 18. merged with, the rotation of the air-guiding member 18 of said predetermined rotation angle thus causes a corresponding rotation of the display portion 41 by the same predetermined rotation angle. The openings 40A, 40B are advantageously:

- in such a way that when the air-guiding element 18 assumes the first air direction configuration, the colored area 43 on the upper side of the disk 42 of the display portion 41 is visible by the user through the aperture. (FIG. 22, left), located opposite one of the openings 40A, 40B, and then

- in this way that when the air-guiding element 18 assumes the second air direction configuration through rotation by the predetermined rotation angle, the colored area 43 is then visible by the user through the aperture (FIG. 22 , right), is constructed and arranged in such a way that it is positioned opposite the other of the openings 40A, 40B.

As already mentioned above, the predetermined angle of rotation is 180° in the example shown in the figures, and the air-guiding element 18 advantageously changes its angular configuration twice, so that the When rotated 360° about its axis of rotation (D-D') under the influence of two successive pushes, it alternates between the first and second air direction configurations. As shown in the figure, the openings 40A, 40B are advantageously arranged on both sides of the combined rotation axis of the air-guiding member 18, the rotational engagement part 35 and the display part 41. Here, the display portion 41 includes a disk 42 extending radially with respect to the axis of rotation of the display portion 41, the upper side of which is directed toward the side of the button 32 with openings 40A, 40B. So, for example, it has an area 43 occupying half of the upper surface of the disc.

Of course, other designs and configurations of indicator systems may also be considered. In particular, it is also conceivable to implement an indicator system comprising a luminous visual selection indicator and thus electrically controlled. Moreover, in the embodiment shown in the figures, the visual selection indicator is visible from the top of the blow head 10 of the hair styling device 1, while the indicator system thus makes the hair styling device 1 even more usable. In this way, which makes it convenient and intuitive, the light-emitting or It may also advantageously be provided to include a visual selection indicator that is not.
