Description

Technical Field

[0001] This invention relates to the general technical 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 airflow to dry hair and / or facilitate hair styling.

[0002] More specifically, the present invention relates to a hair styling device, comprising an air supply module for generating airflow, a heating element for increasing the temperature of the airflow generated by the air supply module, a handle for holding by hand, and an air supply head connected to the handle. Background Technology

[0003] A handheld hair dryer-type hair styling device is known to include a handle and a nozzle, the nozzle including an air outlet for directing a powerful airflow of hot or cold air toward the user's hair. Even though this hair dryer is primarily used for drying wet hair by evaporating moisture through the blowing airflow (drying function), it can also be combined with a number of detachable accessories designed to facilitate hair styling (styling aid function). To secure it to the hair dryer head and to allow the airflow from the nozzle to pass through, these accessories—e.g., diffuser or concentrator types—form different end caps that alter the shape of the airflow from the hair dryer's nozzle.

[0004] While existing hair dryers can meet basic needs, they still have some drawbacks. Especially when switching from drying mode to styling mode, users typically need to adjust the hairdryer to achieve the optimal airflow temperature and speed. However, users may forget to make these adjustments or be unsure which optimal setting to use for the desired hairstyle. This not only risks failing to achieve the desired result but also risks damaging the hair.

[0005] Furthermore, when switching a hair dryer from drying mode to styling mode, users need to assemble / disassemble the accessories. This process has proven to be tedious at times and carries a significant risk of burns while handling the accessories. There is also a risk of accessories being lost, especially when they are not properly organized in inaccessible locations and cannot be found when the user needs them. Summary of the Invention

[0006] Therefore, the objective of this invention is to provide a novel multifunctional hair styling device that is particularly simple and intuitive to use.

[0007] Another objective of this invention is to propose a novel hair styling device that conforms to ergonomic design.

[0008] Another objective of this invention is to propose a novel hair styling device with a particularly simple and compact structure.

[0009] Another objective of this invention is to provide a particularly robust and reliable new type of hair styling device.

[0010] Another objective of this invention is to provide a novel hair styling device that allows for particularly efficient drying and styling in a comfortable and relaxed manner.

[0011] The objective of this invention is achieved through a hair styling device comprising an air supply module for generating airflow, a heating element for increasing the temperature of the airflow generated by the air supply module, a handle for hand gripping, and an air supply head connected to the handle. The hair styling device is characterized in that the air supply head has at least one first air outlet and a second air outlet, and the air supply head is movably mounted relative to the handle between at least one first position and one second position. In the first position, the airflow exits from the air supply head through the first air outlet; in the second position, the airflow exits from the air supply head through the second air outlet. Furthermore, the hair styling device includes an automatic adjustment device for the air supply module and the heating element, the automatic adjustment device controlling the operation of the air supply module and the heating element at the positions occupied by the air supply head relative to the handle.

[0023] The hair styling device 1, 1' according to the invention is designed to be held and operated by hand. Therefore, it relates to a manually operated, preferably handheld, hair styling device that generally provides better operability at home for users lacking professional skills, especially styling skills, including not only drying hair but also combing and styling it.

[0024] Preferably, according to Figures 1 to 5 In the first embodiment shown, the hair styling device 1 is configured as a hair dryer (or hair dryer) that dries the user's damp hair by blowing hot or cold air directly onto the hair, while also making hair styling easier. However, the invention is not limited to this specific embodiment; for example, the invention can also be implemented according to… Figures 6 to 10 The second embodiment shown is implemented as a hair styling device 1' consisting of a blow-drying comb. Alternatively, the invention can also be implemented with other handheld hair styling devices, including those that deliver airflow to the user's hair, particularly for styling purposes, such as direct contact with the hair (combing, straightening, etc.).

[0025] For the sake of brevity, this instruction manual mainly focuses on hair dryer-type hair styling equipment 1 ( Figures 1 to 5 ) and hair styling equipment with hair dryer and comb 1' ( Figures 6 to 10 Unless otherwise indicated, the technical features associated with the hair styling device of the first embodiment are preferably interchangeable with the technical features associated with the hair styling device of the second embodiment, with necessary modifications (and vice versa). Components that are identical or similar between the two embodiments shown in the drawings are referred to by the same reference numerals in this specification.

[0026] According to the hair styling device 1, 1' of the present invention, a handle 2 (or grip) for manual holding is provided for a user to hold and operate the hair styling device 1, 1'. The handle 2 extends between a first end 3 and an opposing second end 4, preferably the second end 4 along the length of the first central axis A-A'. In the embodiment shown, the handle 2 is integrally formed—or assembled as a single unit—and is generally tubular (e.g., with a circular or elliptical cross-section, continuous or discontinuous), and its size is adjusted to ensure a good grip by the user.

[0027] The hair styling devices 1, 1' also include an air delivery module 5 for generating (powerful) airflow, and an air delivery head 6 connected to the handle 6. The airflow generated by the air delivery module 5 is guided outside the hair styling devices 1, 1' through the air delivery head 6, allowing the airflow to be directly sprayed onto the user's hair. Preferably, the air delivery 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 illustrated, the air delivery head 6 thus constitutes one end of the hair styling devices 1, 1'.

[0028] More specifically, the air outlet 6 has at least one first air outlet 7 and one second air outlet 8 that are preferably separate from each other (different from each other and do not overlap). Preferably, the air outlet 6 is configured to rotate relative to the handle 2 between at least one first position and one second position, with the airflow from the air outlet 6 exiting from the first air outlet 7 at the first position and the airflow from the air outlet 6 exiting from the second air outlet 8 at the second position, the above components forming a unified sub-assembly. On the other hand, in the hair styling device 1 according to the invention, 1' is configured to allow selection of one of the first air outlet 7 and the second air outlet 8 of the air outlet 6 by moving the air outlet 6 relative to the handle 2 (that is, by changing the layout, changing the position), through which the air outlet 6 blows airflow.

[0029] Regardless of the position of the air outlet 6 relative to the handle 2 of the hair styling device 1, 1', the air outlet 6 is preferably designed to be permanently connected to the handle 2 of the hair styling device 1, 1', and the user (under normal use) cannot detach the air outlet 6 from the handle 2 of the hair styling device 1, 1'.

[0030] Preferably, as shown in the embodiment, the blower head 6 is rotatably mounted relative to the handle 2 about a second axis B-B'. In other words, the blower head 6 is preferably connected relative to the handle 2 via a pivot, allowing it to rotate relative to the handle 2. Therefore, the hair styling device 1, 1' is preferably designed and configured to allow the user to alternately select one of a first air outlet 7 and a second air outlet 8 by pivoting the blower head 6 relative to the handle 2, wherein the blower head 6 blows air through the first air outlet 7 and the second air outlet 8. More preferably, as shown, the second axis B-B' about which the blower head 6 rotates relative to the handle 2 coincides with a first axis A-A' extending from the handle 2. Furthermore, the second axis B-B' may also be parallel to the first axis A-A' (and may be more or less offset relative to the first axis A-A'). Therefore, the kinematics of the blower head 6 are simple and reliable, and allow the user to intuitively operate the hair styling device 1. Alternatively, the second axis B-B' intersects the first axis A-A' at an angle typically between 5° and 15°.

[0031] In other words, other movements of the air outlet 6 relative to the handle 2 are clearly predictable. For example, according to an alternative form not shown in the figure, the air outlet 6 can translate relative to the handle 2, for example, moving along an axis parallel to or coincident with the first axis A-A' of the handle 2, or even moving along an axis perpendicular to the first axis A-A' of the handle 2. The air outlet 6 can also perform, for example, pure translation, coupled sliding, or helical translation relative to the handle 2.

[0032] Preferably, the first air outlet 7 and the second air outlet 8 have openings with different geometries. Furthermore, the effective cross-section of the air outlet channel of the first air outlet 7 is defined by one (or more) profiles, the shape of which differs from the corresponding effective cross-section of the air outlet channel of the second air outlet 8. Therefore, the airflow from the air inlet 6 has different airflow profiles depending on the selected air outlet 7 or 8, allowing the user to use the hair styling devices 1, 1' according to at least two different blowing patterns.

[0033] Accordingly, the first air outlet 7 and the second air outlet 8 are preferably configured to blow out or spray out two different airflow profiles, namely the first airflow and the second airflow, respectively, so that the user can perform different operations on the hair. For example, the first airflow can correspond to a wider and more dispersed profile with a larger flow rate (e.g., 70m). 3 The first drying airflow (50 m³ / h) ensures the user can quickly dry their hair. The second airflow can correspond to a more concentrated and narrow profile with a relatively small flow rate (e.g., 50 m³ / h). 3The second drying airflow ( / h) ensures that the user can precisely select the area of ​​their hair to be styled. This allows the user to subtly and easily achieve hairstyles such as waves, or conversely, straighten their hair.

[0034] For example, in Figures 1 to 5 In the first embodiment shown, the hair styling device 1 is configured as a hair dryer, and the first air outlet 7 has a generally circular opening. Figure 2 ), while the second air outlet 8 ( Figure 1 and 3 The nozzle 6 has a roughly elongated elliptical opening. Based on this, when the nozzle 6 is in the first position relative to the handle 2, the hair styling device 1 can dry wet hair in a conventional manner. The first airflow from the nozzle 6 is formed near the first air outlet 7, and its outline is roughly cylindrical or conical. When the nozzle 6 is in the second position relative to the handle 2, the hair styling device 1 can not only dry hair but also easily style it (e.g., comb it). The second airflow from the nozzle 6, forming an air wave near the second air outlet 8, allows the user to precisely select the area of ​​hair to be treated, and hair styling can also be achieved using airflow.

[0035] According to, but not limited to, the opening of the first air outlet 7 is preferably capable of generating a first dry airflow, and the opening has an effective cross-section of a first air passage, which is preferably 707 mm. 2 Up to 1963mm 2 For example, equal to 962mm 2 (The first air outlet, with a circular opening, preferably has a diameter of 30 to 50 mm, most preferably 35 mm). The opening of the second air outlet 8 preferably has an effective cross-section of a second air channel, through which air flows. For example, the effective cross-section of the second air channel is 240 mm. 2 Up to 640mm 2 For example, equal to 360mm 2 (The corresponding second air outlet 8 is rectangular, with a length of about 60 to 80 mm and a width of about 4 to 8 mm, preferably about 60 mm in length and about 6 mm in width).

[0036] exist Figures 6 to 10 In the second embodiment shown, the hair styling device 1' is configured as a hair dryer comb, and the first air outlet 7 may, for example, have a generally elongated elliptical opening. Figure 7 As for the second air outlet 8 ( Figure 6 and 8The hair styling device 1' has openings consisting of numerous holes, typically circular, distributed between rows of bristles (or bristles) of the comb. Thus, when the air outlet 6 is in the first position relative to the handle 2, the hair styling device 1' can perform, for example, a pre-drying operation using a first airflow with a wide and dispersed but relatively large flow rate. When the air outlet 6 is in the second position relative to the handle 2, the hair styling device 1' can perform, for example, a final drying operation using a second airflow with a more concentrated but relatively smaller flow rate blowing from between the bristles (or bristles) of the comb.

[0037] Accordingly, the hair styling device 1, 1' according to the present invention allows the user to select at least one first usage mode (e.g., drying hair) and one second usage mode (e.g., hair styling) by changing the layout or position of the air supply head 6 relative to the handle 2 (preferably by simply rotating the air supply head 6 relative to the handle 2). This method allows for particularly simple and quick adjustment of the airflow profile according to different operations on the hair.

[0038] It is foreseeable that the first and second air outlets are assembled to each other as detachable components (e.g., by snaps, screws, press-fitting, etc.) in the remaining position of the air head that can rotate relative to the handle (variations not shown in the figures), which does not exceed the scope of the invention. In fact, this ensures that the user can equip a hair styling device 1, 1' with two separate air outlets of different cross-sectional shapes (instead of a single air outlet, as is the case with conventional hair dryers), and also ensures that the user can use these air outlets continuously without removing / reinstalling parts, while still retaining the option to replace one or the other part, selecting these accessories according to the specific purpose the user desires for the hair styling device.

[0039] However, advantageously, the blow-dry head 6 forms a cohesive assembly rather than being disassembled by the user, and the first air outlet 7 and the second air outlet 8 are constituted by one or more non-removable parts belonging to the blow-dry head 6 (in normal use). Therefore, by displacement, the position of the blow-dry head 6 relative to the handle 2 of the device 1, 1' changes (preferably by rotation), allowing the user to very significantly select one or the other of the first air outlet 7 or the second air outlet 8, thus advantageously selecting their desired airflow profile without having to install or remove any accessories from the hair styling device 1, 1'. Thus, the user benefits from the ease and speed of use of the device 1, 1' and is assured that no components of the device will be lost.

[0040] To ensure ease of use in all situations, particularly for styling the hair at the back of the user's head, the first air outlet 7 and the second air outlet 8 are preferably configured such that the airflow generated by the air delivery module 5 is blown out by the air delivery head 6 in a direction intersecting the extension direction of the first axis A-A', preferably in a substantially orthogonal direction. Particularly preferably, the hair styling devices 1, 1' are designed and constructed such that the air delivery head 6 blows airflow in substantially the same direction, regardless of whether the air delivery head 6 is in a first or second position relative to the handle 2. Therefore, the user can selectively use the first and second air delivery heads 6 of the hair styling devices 1, 1' without adjusting their manual grip position on the handle 2 or changing the overall spatial position of the hair styling devices 1, 1'.

[0041] In a preferred embodiment, the air outlet 6 is rotatable relative to the handle 2. As shown in the preferred embodiment, the transition of the air outlet 6 from the first position to the second position is preferably achieved by rotating the air outlet 6 180° about the second axis B-B'. In other words, the air outlet 6 of the hair styling device 1, 1' is designed and configured such that the first air outlet 7 and the second air outlet 8 of the air outlet 6 are arranged on either side of the second axis B-B' on which the air outlet 6 rotates relative to the handle. This arrangement facilitates simple and intuitive operation of the hair styling device 1, 1' by the user.

[0042] Regardless of how the air outlet 6 moves relative to the handle 2, the first and second positions of the air outlet 6 are preferably stable positions, whereby the air outlet 6 cannot unexpectedly detach from its position without active operation by the user. In this case, the hair styling device 1, 1' preferably includes a device (not shown) for fixing the air outlet 6 relative to the handle 2 in the first and second positions, such as a pair of magnets, a "cooking bowl" or any other known suitable method.

[0043] It should be noted that, as is understood, the present invention is not limited to a blower head 6 comprising only two air outlets 7 and 8, particularly one that is rotatable relative to the handle 2 and whose air outlets are only 180° apart with respect to the second axis B-B', although this assumption is retained in the preferred embodiment shown in the figures. In practice, the blower head 6 could easily include more separate air outlets with different geometric cross-sections (e.g., 3 or 4), which the user could select by rotating relative to the handle and blow air onto the head at the corresponding different positions.

[0044] These three or four (or more) air outlets are regularly distributed in a sector shape with equal angles around the second axis of rotation B-B', depending on the number of air outlets. Therefore, for example, it is conceivable to arrange three independent air outlets, separated from each other and with different cross-sectional geometries, such that the air outlets allow the air supply head to be switched from a first position to a second position, and then from that second position to a third position, for example, corresponding to a 120° rotation of the air supply head around the second axis B-B'. For example, it is also possible to consider arranging four independent air outlets, separated from each other and with different cross-sectional geometries, such that the air supply head can be switched from one position to another, for example, corresponding to a 90° rotation of the air supply head around the second axis B-B'. Furthermore, the rotation of the air supply head around the second axis B-B' to switch the air outlets from one position to another can obviously result in different rotation angles depending on the position / total number of air outlets and the 360° ratio.

[0045] The air supply module 5 of the hair styling equipment 1, 1' preferably includes an electric fan unit 10, which itself includes an electric motor 11. The electric fan unit 10 may include a conventional axial fan with a spiral shape. Alternatively, the electric fan unit 10 preferably includes 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, and the airflow at that internal pressure is substantially similar to that of a spiral fan, but this fan has a lower rotational speed, thus producing less noise from the electric fan unit 10. 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 lightweight than conventional brushed motors. They are quieter, more energy-efficient, and offer greater flexibility and higher precision in adjusting rotational speed.

[0046] Preferably, the air supply module 5 embedded in the hair styling device 1, 1' is placed inside the handle 2 or inside the air supply head 6. More preferably, as shown in the embodiment, the air supply module 5 of the hair styling device 1 is assembled on the first end 3 of the handle 2, and the air supply head 6 is movably (preferably rotatably) mounted relative to the handle 2 at the second end 4 of the handle 2. Thus, the air supply head 6 preferably extends from the second end 4 of the handle 2, while the air supply module 5 extends from the first end 3 of the handle 2. Preferably, the air supply module 5 is fixed to the handle 2 at the first end 3, so that the air supply module 5 has no possibility of rotation relative to the handle 2. Furthermore, the air supply module 5 itself can have a power cord 9 led out, for example... Figures 6 to 10As shown. Therefore, the air supply module 5 of the hair styling device 1, 1' is preferably located away from the air supply head 6 and the handle 2 for holding the hair styling device 1, 1'. Based on this, the size of the air supply module 5 can be determined to economically generate a large airflow without affecting the overall size of the air supply head 6 and the handle 2. Furthermore, by distributing the weight to the other side of the handle 2, this arrangement of the air supply module 5 helps to better balance the weight of the styling device 1, which contributes to ease of use.

[0047] When the air delivery module 5 is disposed inside the handle 2 or assembled on the first end 3 of the handle 2, preferably, the handle 2 may include a guide channel 12 for guiding the airflow generated by the air delivery module 5 toward the air delivery head. Preferably, the guide channel 12 guides the airflow through the handle 2, toward the second end 4 along the direction of the first end 3 of the handle 2. The hair styling device 1, 1' may also preferably include a deflector 13, which is designed and configured to guide the airflow generated by the air delivery module 5 from the guide channel 12 of the handle 2 toward the first air outlet of the first handle when the air delivery head 6 is in the first position. Conversely, when the air delivery head 6 is in the second position, it is guided toward the second air outlet 8.

[0048] exist Figures 1 to 5 In the first embodiment shown, the electric fan unit 10 preferably includes a centrifugal fan 14, and the air delivery module 5 includes a working chamber 15 in the form of a volute, within which the electric fan unit 10 is housed. The working chamber 15, as... Figure 5 As shown, it can be defined by the inner walls of two half-shells 16, 17 assembled together (e.g., fixed with bolts), and simultaneously fixed to the first end 3 of the handle. The air supply module 5 has an air inlet 18 from which the fan 14 axially draws ambient air into the working chamber 15. Preferably, the air outlet communicates with the guide channel 12 of the handle 2, through which the drawn-in air is radially compressed from outside the working chamber 15 into the guide channel 12. The air supply module 5 also preferably includes a grille (removable and repositionable as needed) for protecting the air inlet 18 of the working chamber 15. Specifically, as... Figure 5 As shown, the air intake module 5 is preferably designed and constructed such that the axis of the centrifugal fan 14 of the electric fan unit 10 is substantially orthogonal to the first axis A-A' in the extension direction of the handle 2. The air inlet 18 of the working chamber 15 is preferably configured to draw in ambient air in a direction substantially parallel to the airflow from the air outlet 6, more preferably in the same direction. Of course, it is contemplated that, without departing from the scope of the invention, ambient air may be drawn into the working chamber 15 in a secant direction (e.g., substantially perpendicular to the average direction of the airflow from the air outlet 6).

[0049] for Figures 6 to 10In the second embodiment shown, the hair styling device 1 is configured as a hair dryer comb, and the electric fan unit 10 preferably includes a spiral fan 14. An air delivery module 5 is connected to the first end 3 of the handle 2. The air delivery module 15 includes a working cavity 15 with a substantially cylindrical inner wall, in which the electric fan unit 10 is housed. The electric fan unit 10 is configured such that the axis of the spiral fan 14 is parallel to, and preferably coincides with, a first axis A-A' extending longitudinally along the handle 2. The air delivery module 5 has an air inlet 18, which may be a grille. The fan 14 draws ambient air axially into the working cavity 15 from the air inlet 18. Preferably, the air outlet communicates with the guide channel 12 of the handle 2, and the drawn-in air is radially compressed from outside the working cavity 15 into the guide channel 12.

[0050] Preferably, the air outlet 6 includes a housing 20 that defines the shape and profile of the air outlet 6, and advantageously defines the shape and profile of the end of the hair styling device 1, 1' extending from its handle 2. Preferably, the housing 20 is shaped to allow the user to grip it manually, so that the user can directly apply pressure to the housing 20 (i.e., the air outlet 6) to rotate the air outlet 6 about the second axis B-B' relative to the handle 2, in order to select one of the first air outlet 7 and the second air outlet 8 of the air outlet, and thus select the corresponding operating mode of the hair styling device 1, 1'.

[0051] Preferably, the air supply head 6 includes a nozzle body 19, which is used to direct the air blown out by the hair styling device 1 in the direction of the user's hair. Figures 1 to 5 In the first embodiment shown, the nozzle body 19 is preferably embedded in the housing 20 (or shroud), which may be formed, for example, by a half-shell fastened with snaps or assembled with screws. The housing 20 of the air outlet 6 is rotated by the user about a second axis B-B', causing the nozzle body 19 to also rotate about the second axis B-B'. The housing 20 may be configured to give the air outlet 6 a specific aesthetic appearance, for example... Figures 1 to 5 The shape is roughly cylindrical.

[0052] Preferably, the outer casing 20 of the air outlet 6 extends longitudinally approximately along a third axis C-C', which is orthogonal to the mid-plane of the air outlet 6. The air outlet 6 is configured relative to the handle 2 such that its second axis of rotation B-B' coincides with a first axis A-A' extending longitudinally along the handle 2, and the first axis A-A' and the second axis B-B' are located in the mid-plane of the air outlet 6. Thus, the outer casing 20 preferably extends along the third axis C-C', which is orthogonal to the first axis A-A' extending longitudinally along the handle and the second axis B-B' around which the air outlet 6 rotates, and has a substantially equal distance from the first axis A-A' and the second axis B-B'.

[0053] In addition to the aesthetic effect of symmetry or quasi-symmetry that can be obtained, this particular setup provides a good overall balance and helps to provide the user with good operability.

[0054] In particular, such as Figure 5 As shown in the cross-sectional view, the nozzle body 19 preferably extends along the third axis C-C' that extends longitudinally inside the air supply head 6; on the one hand, the first end of the nozzle body constitutes the first air outlet 7 of the air supply head 6 (as mentioned above, it preferably has a generally circular opening), and on the other hand, the second end located on the opposite side of the nozzle body constitutes the second air outlet 8 of the air supply head 6 (preferably has a generally elongated oval opening in the direction perpendicular to the second axis B-B').

[0055] In this particular first embodiment, the hair styling device 1 further includes a deflector 13, which, as previously described, selectively guides the airflow generated by the air delivery module 5 from the guide channel 12 of the handle 2 to one of the first air outlet 7 and the second air outlet 8, depending on the position of the air delivery head 6. Figure 5 As shown, the deflector 13 preferably includes an elbow tube 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. Therefore, the air outlet 6 preferably rotates about the elbow tube 21 of the deflector 13, causing it to move between the first and second positions.

[0056] As a particularly preferred embodiment, the elbow tube 21 and the handle 2 form an integral structure. Figure 5 This significantly reduces the number of parts in hair styling equipment 1, making it easier to manufacture.

[0057] like Figure 5 As shown, the nozzle body 19 preferably includes an air inlet 22, which has dimensions that mate with the elbow tube 21 of the guide plate, and by means of this air inlet, the elbow tube 21 passes through the nozzle body 19 in the direction of the air supply head 6 about the second axis of rotation B-B'. The elbow tube 21 and the nozzle body 19 are configured relative to each other as follows: when the air supply head 6 is in the first position, the elbow tube 21 directs the airflow in the nozzle body 19 to the first nozzle body end constituting the first air outlet 7 of the air supply head 6, while preferably preventing air leakage from the direction of the second nozzle body end on the opposite side. Conversely, the elbow tube 21 and the nozzle body 19 are configured relative to each other as follows: (after rotating the rotating air supply head 6 180° about the second axis B-B') when the air supply head 6 is in the second position, the elbow tube 21 directs the airflow in the nozzle body 19 to the second nozzle body end constituting the second air outlet 8 of the air supply head 6, while preferably preventing air leakage from the direction of the first nozzle body end on the opposite side. Figure 5As shown in the figure, the deflector 13 (especially its elbow tube 21) and the nozzle body 19 are configured to guide the airflow in the guide channel 12 of the handle 2 in a 90° deflection toward either the first air outlet 7 or the second air outlet 8.

[0058] Obviously, it is foreseeable that the air outlet 6 of the hair styling device 1 will have different designs, such as... Figures 6 to 10 The design shown relates to a second preferred embodiment of the hair styling device 1, 1' according to the present invention.

[0059] Figures 6 to 10 The hair styling device 1' shown is configured as a hair dryer comb, with the air delivery head 6 preferably having a shape generally similar to a conventional hair comb. In this case, the air delivery head 6 extends along a fourth axis D-D', which is parallel to, and preferably coincides with, a second axis B-B' on which the air delivery head 6 rotates relative to the handle 2. Furthermore, as shown, the air delivery head 6 is positioned relative to the handle 2 such that the second axis of rotation B-B' of the air delivery head 6 coincides with the first axis A-A' of the handle 2 extending longitudinally.

[0060] For example, especially in Figure 10 As shown, the air supply head 6 may include a nozzle body 19, which is not mounted as a separate component within the housing 20 of the air supply head 6, but is directly defined by the inner wall of the housing 20. The housing 20 may be constructed from multiple shell-shaped elements assembled together (e.g., secured by snaps or screws) in a manner similar to the first embodiment. The nozzle body 19 then preferably extends along a fifth axis E-E', which is orthogonal to a longitudinal fourth axis D-D' within the air supply head 6. On one hand, the first nozzle body end constitutes the first air outlet 7 of the air supply head 6; on the other hand, the opposite second nozzle body end constitutes the second air outlet 8 of the air supply head 6.

[0061] According to another embodiment, the housing 20 may include at least one post (not shown) disposed at the edge of the housing 20, configured to contact the hair during hair styling operations. This post is preferably heatable, or at least capable of transferring heat from the drying airflow flowing in the nozzle 6 to the hair. For example, the post may be made of a thermally conductive material, such as a metal (steel, aluminum, etc.), and in direct contact with the drying airflow flowing inside the nozzle body 19. For example, the post may extend through the entire housing 20, one side inside the nozzle body 19 to contact the drying airflow, and the other side extending outward to contact the hair. The protruding edge of this post can contact the hair during styling, preferably heated, giving the hair a ribbon-like effect. This protruding effect allows a strand of hair to form a coordinated wave, much like the waves created when rubbing a ribbon with a blade while preparing elegant gift wrapping. Preferably, the housing includes two posts opposite each other, generally parallel, and arranged on either side of the fourth axis D-D', thereby enabling the ribbon-like hair effect to be achieved regardless of the user's experience with hair styling equipment.

[0062] The first air outlet 7 of the air supply head 6 has a generally elongated elliptical opening that is generally parallel to the direction of the fourth axis D-D' extending longitudinally from the air supply head 6. Figure 7 The second air outlet 8 of the blower head 6 may, for example, consist of multiple holes distributed among rows of comb (or hairpins), these holes typically being circular. Figure 6 and 8 ).

[0063] In this second specific embodiment, the hair styling device 1' also includes a deflector 13, which, depending on the position of the air outlet, guides the airflow generated by the air delivery module 5 from the guide channel 12 of the handle 2 from one of the first air outlet 7 and the second air outlet 8 to the other. Figure 5 As shown, the baffle 13 preferably includes an elbow tube 21, which is formed as a closed tapered section, with an axial opening on its inner sidewall. The elbow tube 21, which is fixed relative to the handle 2, extends along the first axis A-A' and extends the air guide channel 12 of the handle 2 to extend out to the second end 3.

[0064] like Figure 5 As shown, the nozzle body 19 preferably includes an air inlet, the size of which matches the size of the elbow tube 21 of the guide plate 13, and by means of the air inlet, the elbow tube 21 can pass through the nozzle body 19 along the second axis B-B' of the blower head 6 about which it rotates. Figures 6 to 10 The second embodiment makes corresponding configurations and arrangements for the elbow tube 21 and the nozzle body 19, which are consistent with those according to... Figures 1 to 5In the first embodiment, the configuration and setting of the elbow tube 21 and the nozzle body 19 are similar or even the same, and can produce essentially the same effect.

[0065] 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 deflectors, more or less inclined, and preferably fixedly installed, so as to ensure a uniform velocity / flow rate distribution of the airflow profile blowing from the air outlet when necessary. For example, in the embodiment shown in the figures, the opening of the first air outlet 7 is equipped with a vane deflector 23, which, combined with the geometry of its opening, is suitable for use on the hair styling equipment 1, 1' for drying / pre-drying purposes. Figures 1 to 5 In the first embodiment, the vane guide 23 is preferably integrally formed with the nozzle body 19. Alternatively, the vane guide 23 may be a separate additional component, such as... Figures 6 to 10 As shown in the second embodiment. Preferably, the geometry of the opening of the second air outlet 8 is adapted to the use of the hair styling equipment 1, 1' for the purpose of achieving or assisting in styling, and it is not equipped with a vane deflector itself.

[0066] Hair styling devices 1, 1' also include a heating element 24 for heating the airflow generated by the air delivery module 5. Preferably, the heating element 24, embedded within the hair styling device 1, 1', can be housed within the air delivery head 6 or the handle 2 (i.e., internally). More preferably, the heating element 24 is (at least partially) housed within the handle 2 (i.e., internally), and more preferably, as in the embodiment shown in the figures, is positioned within the guide channel of the handle 2 in a manner placed between the airflow generated by the air delivery module 5. This configuration can significantly reduce the size and weight of the air delivery head 6 while simplifying the design. The electric heating element is typically an element operating based on the Joule effect principle, preferably with a power greater than 500W. Preferably, the heating element 24 comprises at least one heating resistor obtained by winding an insulating core with conductive metal wire (e.g., nickel-chromium alloy). In the preferred embodiment shown in the figures, the heating element 24 is more precisely composed of an insulating core 25 (e.g., made of mica) with a cross-shaped cross-section wound with metal wire (not shown), and has fixing fins at its ends. Preferably, the hair styling device 1, 1' further includes a thermal insulator 26, such as a tubular component with a circular bottom surface, within which a heating element 24 is disposed, specifically protecting the user from burns by limiting the heating of the handle 2. As shown, the inner wall of the thermal insulator 26 preferably forms all or part of the aforementioned guide channel 12.

[0067] Preferably, the hair styling device 1, 1' further includes an electronic module 27. This module requires no user operation or contact, and is preferably designed to interact (directly or indirectly) with all or some of the components constituting the hair styling device 1. It is typically a circuit board, electronic circuit, printed circuit board (“PCB”), or a collection of electrical, electronic, or electromechanical components within the hair styling device 1, 1'. The electronic module 27 ensures 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 another functional component of the hair styling device 1, 1'. Optionally, the electronic module 27 may include components such as a battery, a display, one or more microcontrollers, etc. Electronic module 27 can also optionally be connected to a number of sensors and sensing elements distributed in hair styling equipment 1, 1' to measure and monitor physical parameters (temperature, voltage and current, air velocity / flow rate, fan speed of air supply module 5, etc.) related to the function of hair styling equipment 1, 1', thereby better controlling the operation of various functional components of hair styling equipment 1, 1'.

[0068] In a more preferred embodiment, the electronic module 27 is designed to control the air supply module 5 and / or heating element 24 of the hair styling devices 1 and 1'. In practice, to control the air supply module 5 and / or heating element 24 of the hair styling devices 1 and 1' separately according to the technology employed, specific control of one (or more) electronic modules or electronic circuits is required.

[0069] For example, when the electronic module 27 is designed to control the heating element 24, the electronic module 27 may include circuitry for controlling the electrical supply and / or specific adjustments (power, temperature, etc.) of the electronic module. As previously mentioned, in a preferred embodiment where the air supply module 2 includes a brushless motor 11, control of the brushless motor 11 can be ensured by the electronic module 27. In this case, the electronic module 27 can be designed to control the current commutation in the stator windings (phase control) based on position sensor data (e.g., Hall effect), ensuring autonomous speed adjustment, etc.

[0070] Preferably, such as Figures 1 to 5 In the first preferred embodiment shown, the electronic module 27 is preferably disposed inside the air supply head 6, preferably outside the airflow inside the air supply head 6. Preferably, the air supply head 6 includes a dedicated cavity 28 for accommodating the electronic module 27.

[0071] This arrangement helps limit the overall size of the hair styling devices 1, 1', especially when the electronic module 27 is designed to control the air delivery module 5 and / or the heating element 24, in which case the heating element is located outside the air delivery head 6. Where, as previously described, the heating element 24 is located inside the handle 2 and / or the air delivery module 5 is mounted inside the handle 2 or at one end of the handle 2, the electronic module 27 is preferably located separately from the heating element 24 and / or the air delivery module 5 it controls. This minimizes the overall size of the handle 2 and / or the air delivery module 5 connected thereto.

[0072] However, considering the movable (preferably rotating) nature of the air outlet head 6, on the one hand, the heating element 24 and / or the air supply module 5 are located outside the air outlet head 6 (or any other functional component of the hair styling device 1, 1' that may be connected to the electronic module 27 and located outside the air outlet head 6), and on the other hand, the electronic module is located inside the air outlet head, it may be difficult to ensure a simple and secure electrical connection. This is why... Figures 1 to 5 In the first preferred embodiment shown, the electronic module 27 is preferably installed inside the air outlet 6, thereby maintaining relative stillness with respect to the air outlet module 5 and / or the heating element 24 outside the air outlet 6. In this case, as Figure 5 As shown, the nozzle body 19 may be provided with an auxiliary hole 29, which is opposite to the air inlet. The elbow tube 21 of the guide plate 13 passes through the nozzle body 19 via this auxiliary hole 29. The height of the auxiliary hole 29 is flush with the nozzle body 19 or partially extends beyond the nozzle body 19, so that the electronic module 27 can be directly or indirectly fixed to the elbow tube 21 by the support member 30. Obviously, other suitable installation methods can be foreseen. For example, depending on the size, the electronic module 27 can be installed on the back of the elbow tube 21 of the guide plate 13.

[0073] Therefore, the electrical connection between the heating element 24 and / or the air supply module 5 and the electronic module 27 disposed in the air supply head 6 can be achieved very simply using, for example, conventional conductive wires (not shown), without the risk of damaging the wires due to twisting, and without the need for complex moving electrical connection devices (e.g., rotatable connector types). Thus, the manufacturing cost of the hair styling device 1 can be reduced and its reliability improved.

[0074] Although the electronic module 27 is located inside the air outlet 6, and preferably outside the airflow passing through the air outlet 6, the temperature of the electronic module 27 is likely to rise significantly if the airflow generated by the air outlet module 5 is heated by the heating element 24 before being blown out of the device 1 by the air outlet 6. 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 may still generate its own heat under normal operating conditions due to the influence of the current. If the temperature of the electronic module 27 is not controlled and exceeds a certain threshold, the risk of failure of the electronic module 27, and even the entire device, will increase regardless.

[0075] For this purpose, the hair styling device 1, 1' may particularly preferably include a diversion channel 31 for capturing a portion of the airflow generated by the air supply module 5, thereby ensuring cooling of the electronic module 27. To ensure forced cooling of the electronic module 27, this portion of the airflow must be guided and blown as close as possible to the electronic module; therefore, the diversion channel 31 is designed and constructed to collect and transfer a portion of the forced airflow generated by the air supply module 5 before the heating element 24 heats the airflow, if necessary.

[0076] When the air supply module 5 is located inside the handle 2 or at the first end 3 of the handle 2, the diversion channel 31 preferably extends at least partially within the handle 2. Therefore, the diversion channel 31 is preferably integrated into the handle 2. As a more preferred embodiment, the hair styling device 1, 1' can be configured such that the guide channel 12 and the diversion channel 31 extend within the handle in a manner parallel to each other, preferably along the first axis A-A' of the handle.

[0077] For example, in Figures 1 to 5 In the first preferred embodiment shown, on the one hand, the diversion channel 31 opens at the air outlet of the working chamber 15 of the air supply module 5 to capture part of the airflow (cold air, i.e., air that has not yet been heated by the heating element 24) generated by the air supply module 5; on the other hand, it is directly adjacent to the electronic module 27 disposed in the air supply head 6. Figure 5 In the illustrated embodiment, the diversion 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 along the length of the handle 2. This arrangement also facilitates cooling of the handle 2, which improves the user comfort of the hair styling devices 1, 1'. The diversion channel 31 may also preferably extend at the height of the air outlet 6 between the double walls 32 formed by the back of the elbow tube 21, and then through the support member 30, to which the electronic module 27 is fixed as described above.

[0078] Preferably, hair styling devices 1, 1' may further include circuitry for re-ejecting a portion of the airflow captured in the (main) airflow blown out by the air outlet 6, such that the portion of the airflow captured by the diversion channel 31 and allocated to the electronic module 27 for cooling can be blown directly onto the user's hair through the air outlets 7 and 8 on the air outlet 6. In this way, the cooling of the electronic module 27 has virtually no impact on the flow rate of the airflow generated by the air delivery module 5 and blown out from the air outlet 6. For example, the nozzle body 19 of the air outlet 6 may be provided with a hole (not shown) for re-ejecting a portion of the airflow collected directly inside the nozzle body 19, preferably located downstream of the elbow tube 21 of the guide plate 13. Alternatively (or supplementarily), the housing 20 of the air outlet 6 may be provided with an vent (or equivalent structure) through which all or part of the captured airflow can escape from the air outlet 6, i.e., from the hair styling devices 1, 1'. In this way, the portion of the airflow used to cool the electronic module 27 is discharged from the hair styling device 1, 1' without affecting (or at least not significantly affecting) the temperature of the (main) airflow blowing directly onto the user's hair from the air outlet 6.

[0079] Typically, the dimensions of the diversion channel 31 are determined to allow airflow within it to be between 1 and 10 m. 3 A flow rate of / h is passed through, thereby effectively cooling the electronic module 27.

[0080] According to the present invention, hair styling equipment 1, 1' includes an automatic adjustment device 33 for operating the air supply module 5 and / or the heating element 24. This automatic adjustment device 33 automatically controls the air supply module 5 and / or the heating element 24 based on the position of the air supply head 6 relative to the handle 2. In other words, these adjustments are not directly operated by the user, but are indirectly achieved by changing the position of the air supply head 6 relative to the handle 2. Therefore, the automatic adjustment device 33 (if necessary via the aforementioned electronic module 27) cooperates with the air supply module 5 and the heating element 24 to automatically adjust accordingly based on changes in the position of the air supply head 4 relative to the handle 2 made by the user.

[0081] This automatic adjustment device 33 can also be obtained by any other known means of using the aforementioned automatic control function. For example, the automatic adjustment device 33 may specifically include one or more switches or contactors (electric, optical, mechanical, or even magnetic) and / or one or more potentiometers, and / or one or more position sensors for sensing the position of the air outlet 6 relative to the handle 2. These are typically located at the interface between the air outlet 6 and the handle 2 and are electrically connected to the air supply module 5 and / or the heating element 24 (if necessary via the aforementioned electronic module 27). The automatic adjustment device 33 can be activated or deactivated according to the position of the air outlet 6 relative to the handle 2, thereby adjusting the relevant operation of the air supply module 5 and the heating element 24. In this way, the corresponding operation of the air supply module and / or the heating element can preferably be preset according to the first and second positions of the air outlet 6, preferably, the air supply module and / or the heating element simultaneously correspond to different preset functions.

[0082] Preferably, the automatic adjustment device 33 of the air supply module 5 and the heating element 24 is designed and configured such that the first position of the air supply head 6 corresponds to the first velocity F1 and the first temperature T1 of the airflow blown out by the air supply head 6 (i.e., through the first air outlet 7 of the air supply head 6). Similarly, the automatic adjustment device 33 can preferably be designed and configured such that the second position of the air supply head 6 corresponds to the second velocity F2 and the second temperature T2 of the airflow blown out by the air supply head 6 (i.e., through the second air outlet 8 of the air supply head 6).

[0083] In a more preferred embodiment, the first velocity F1 and the second velocity F2 of the airflow blown out by the air outlet 6 are different from each other, and the first temperature T1 and the second temperature T2 of the airflow blown out by the air outlet 6 can also be different from each other. However, it is foreseeable that the automatic adjustment device 33 can be configured to cooperate with the air supply module 5 and the heating element 24, so that regardless of the position of the air outlet 6, and thus regardless of the selected air outlet 7 or 8, and the opening shape of the air outlet 7 or 8, the airflow can be automatically blown out at the same speed or temperature.

[0084] Thus, either the first or second position of the air outlet 6 can be automatically paired with the speed and temperature of the airflow, and this pairing is preferably preset and optimized according to the specific purpose of the hair styling device 1, 1'. For the purpose of drying hair using the hair styling device 1, the first speed F1 and first temperature T1 of the airflow from the air outlet 6 are preferably preset and optimized. The first position of the air outlet 6 preferably corresponds to the so-called hair drying position. Similarly, for the purpose of styling hair using the hair styling device 1, the second speed F2 and second temperature T2 of the airflow from the air outlet 6 can also preferably be preset and optimized. The second position of the air outlet 6 therefore preferably corresponds to the so-called hair styling (setting) position.

[0085] Hereinafter, illustratively and not limitingly, the first temperature T1 of the airflow emitted from the air outlet 6 is preferably between 64 and 104°C, more preferably equal to 84°C. The first velocity F1 of the airflow emitted from the air outlet 6 is preferably between 35.7 km / h and 99.0 km / h, more preferably equal to 72.8 km / h. The second temperature T2 of the second airflow emitted from the air outlet 6 is preferably between 60 and 100°C, more preferably equal to 80°C. The second velocity F2 of the airflow emitted from the air outlet 6 is preferably between 78.1 km / h and 208.3 km / h, more preferably equal to 138.9 km / h.

[0086] Preferably, the automatic adjustment device 33 is designed and configured such that when the air outlet 6 is in the first position, it corresponds to the first power P1 of the heating element 24 and the first rotational speed V1 of the fan 14 of the electric fan unit 10. For the purpose of drying hair using the hair styling devices 1, 1', the first power P1 and the first rotational speed V1 can preferably be preset and optimized. Here, illustratively and not limitingly, the first power P1 of the heating element 24 is preferably between 1000W and 2000W, more preferably equal to 1500W. The first rotational speed V1 of the fan 14 is preferably between 13000rpm and 17000rpm, more preferably equal to 15000rpm. Depending on the size of the air delivery module 5, this first rotational speed V1 of the fan 14 corresponds to the flow rate Q1 of the first airflow blown by the air outlet 6, which is preferably 50m³ / min. 3 / h to 90m 3 Between, more preferably equal to 70m 3 / h.

[0087] Similarly, the automatic adjustment device 33 is preferably designed and configured such that when the air outlet 6 is in the second position, it corresponds to the second power P2 of the heating element 24 and the second rotational speed V2 of the fan 14 of the motor-fan unit 10. For the purpose of assisting in hair styling with the hair styling device 1, the second power P2 and the second rotational speed V2 can preferably be preset and optimized. In this case, illustratively and not limitingly, the second power P2 of the heating element 24 is preferably between 500W and 1500W, more preferably equal to 1000W. The rotational speed V2 of the fan 14 is preferably between 14000rpm and 18000rpm, more preferably equal to 16000rpm. Depending on the size of the air delivery module 5, this second rotational speed V2 of the fan 14 corresponds to the flow rate Q2 of the second airflow blown by the air outlet 6, which is preferably 30m³. 3 / h to 70m 3 Between / h, more preferably equal to 50m 3 / h.

[0088] If necessary, according to the second embodiment of the present invention, when the hair styling device 1' is configured as a hair dryer comb, the speed, power and flow rate values ​​mentioned above can be reduced by 60%, while the temperature values ​​mentioned above can remain basically the same.

[0089] Therefore, the hair styling devices 1, 1' according to the present invention are simpler and more intuitive for users because the operation of the air supply module 5 and / or heating element 24 can be preset and pre-adjusted according to the position of the air supply head 6 relative to the handle 2. Therefore, during the manufacturing process of the hair styling devices 1, 1', the optimal adjustment operation can be pre-set based on the position of the air supply head 6. Thus, regardless of their hair styling experience, users of the hair styling devices 1, 1' can greatly optimize the styling results.

[0090] Preferably, the hair styling devices 1, 1' are designed such that their air delivery head 6 can be positioned relative to the handle 2 in at least one third position (or even a fourth position) different from the first and second positions, in which the automatic adjustment device 33 of the air delivery module 5 and the heating element 24 is designed to stop the operation of the hair styling devices 1, 1'. In other words, the automatic adjustment device 33 is designed and configured to cooperate with the air delivery module 5 and the heating element 24 such that when the air delivery head 6 is in the third position relative to the handle 2, the speed of the fan 14 of the electric fan assembly 10 of the air delivery module 5 and the power of the heating element 24 are both zero. For this purpose, the automatic adjustment device 33 can be designed to interact, for example, directly with the corresponding power supply circuits of the air delivery 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 hair styling devices 1, 1' by simply changing the position of the air delivery head 6 relative to the handle 2 (preferably a simple rotation) without having to directly operate any conventional on / off switch.

[0091] Preferably, the hair styling devices 1, 1' are designed and configured such that the third position (or stop position) corresponds to the position of the air delivery head 6 relative to the handle 2 between the first and second positions. For example, in this case, the hair styling devices 1, 1' are designed to rotate the air delivery head 6 180° about the second axis B-B' to change it from the first position to the second position, so the change to the third position is intuitive for the user, corresponding to rotating the air delivery head 6 about the second axis B-B' from one of the first and / or the other by 90°. Alternatively, where the air delivery head 6 can move rather than rotate relative to the handle 2, for example, translate relative to the handle 2 between the first and second positions, it is foreseeable that the third stop position corresponds to a position where the air delivery head 6 is equidistant from the first and second positions in the translational direction.

[0092] Optionally, and as shown in the figures, hair styling devices 1, 1' may also include a manual adjustment device 34 allowing the user to adjust the air supply module 5 and / or the heating element 24. The adjustment device involved may be, for example, a rocker switch, button, and / or sliding or rotary adjustment device, which the user can directly act upon to precisely adjust the air supply module 5 and / or the heating element 24 when necessary. 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 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 device 34 may be designed and configured to start / stop the hair styling device 1, 1', i.e., to completely stop operation. In this case, it is foreseeable that the air supply head 6 does not need to be designed with a (third) stop position.

[0093] As for the location of the manual adjustment device 34, it can be located at the handle or at the air supply module 5. When it is located at the latter, it is assembled at the first end 3 of the blower module 5 as shown in the figure.

[0094] In addition to the automatic adjustment device 33 for the air supply module 5 and the heating element 24, the hair styling equipment 1, 1' preferably also includes a manual start / stop device for the heating element 24. Thus, regardless of the position of the air outlet 6 (i.e., whether air outlet 7 or 8 is selected) and regardless of the selected operation adjustment method for the air supply module 5 and / or the heating element 24, the user can stop the operation of the heating element 24 at any time, thereby blowing only cold air (i.e., air not heated by the heating element 24) onto the hair.

[0095] For example, this manual start / stop device for the heating element 24 can be constituted by a conventional electric switch, rocker switch, or push-button switch located at the handle 2 of the hair styling device 1, 1', which connects to the heating element 24 and its power supply circuit. Alternatively and more preferably, such as Figures 1 to 5 As shown, the manual start / stop device for the heating element 24 includes a mechanical rocker switch 34, which protrudes from the handle 2 and is mechanically connected to a microswitch 35 housed in the air supply module 5 via a lever (not shown) housed within the handle 2. This microswitch 35 is itself assembled at the first end 3 of the handle. By removing a portion of the manual start / stop device for the heating element 24 in this way, space can be freed up inside the handle 2 primarily for housing the heating element 24.

[0096] In the embodiments shown in the accompanying drawings and described above, the hair styling devices 1, 1' are preferably designed to allow the user to move the air outlet 6 from one position to another, with the user holding the handle 2 of the hair styling device 1, 1' with one hand and the air outlet 6 with the other, so that the air outlet 6 rotates relative to the handle 2 about the axis of rotation B-B'. However, according to variations not shown, it is entirely foreseeable that, for example, the rotation (or translation, depending on the selected movement mode) of the air outlet 6 can be electrified or simply mechanized using a motor controlled by a switch provided on the handle 2, for example, using a trigger system and a cam. In this case, the user can achieve rotation (or translation) of the air outlet 6 in a simplified manner by holding the handle 2 with one hand.

[0097] The functions and uses of hair styling equipment 1, 1', are illustrated in the embodiments shown in the accompanying drawings.

[0098] The air outlet 6 of the hair styling device 1, 1' is initially positioned relative to the handle 2 in a first position. The user grasps the handle 2 of the hair styling device 1, 1' with one hand, preparing to position it by pointing the first air outlet 7 of the air outlet 6 towards the direction of wet hair. Thanks to the automatic adjustment device 33 that adjusts the air supply module 5 and the heating element 24, the air outlet 6 can blow an optimized airflow in the direction of the user's hair, such as for pre-drying or drying hair.

[0099] Then, after using the hair styling devices 1, 1' for the desired time, for example, until the hair is sufficiently dry or pre-dried, the user grasps the air outlet 6 with their other hand, rotating it relative to the handle 2 about axis B-B', positioning the air outlet 6 in its second position. Airflow then exits through the second air outlet 8 of the air outlet 6. Thanks to the automatic adjustment device 33 that adjusts the air supply module 5 and the heating element 24, the air outlet 6 can blow optimal airflow towards the user's hair, for example, for hair styling.
