Description

Technical Field

[0001] The present invention relates to the general technical field of hairdressing devices, such as home hairdressing devices, and more particularly to the field of portable electric hairdressing devices designed to emit airflow for drying hair and / or facilitating hair styling. Background Art

[0002] As a known hand-held hairdressing device, there is a handle and an air supply head, wherein the air supply head comprises an air outlet for directing a strong hot or cold air flow toward the hair of the user. Even if the hair dryer is mainly used for drying wet hair (hair drying function) by evaporating water through the action of the blown air flow, it can also be combined with a certain number of detachable accessories designed to facilitate hair styling (auxiliary styling function). In order to be fixed to the head of the hair dryer and to allow the air flow blown from the air supply head to pass through, the above accessories, such as diffuser type or air collection type, form different end sleeves, which change the shape of the air flow blown from the air supply head of the hair dryer.

[0003] Although such existing hair dryers can basically meet the needs, they still have some drawbacks. In particular, when switching the hair dryer from a drying mode to an auxiliary styling mode, the user needs to assemble / disassemble the accessories. This operation has proven to be annoying at times, and there is also a considerable risk of burns when operating the accessories, as well as the risk of losing the accessories when the accessories are not simply organized in an inaccessible place and when the user wants to use the accessories but cannot obtain them.

[0021] The hairdressing device 1, 1' according to the present invention is designed to be held and operated by hand. Therefore, it is a handheld, manually operated hairdressing device that can provide better operability for users who lack professional skills, especially hairdressing skills, at home, that is, not only drying hair, but also combing and styling hair.

[0022] Preferably, according to Figures 1 to 5 In the first embodiment shown, the hairdressing device 1 is formed as a hair dryer (or hair dryer), which dries the user's wet hair by blowing hot or cold strong air directly to the hair, and also makes hair styling easier. However, the present invention is not limited to this specific embodiment. For example, the present invention can also be implemented according to Figures 6 to 10 The second embodiment shown is implemented as a hairdressing device 1' in the form of a hair-drying comb. Alternatively, the present invention can also be implemented by other portable hairdressing devices: including a function of blowing air to the user's hair, especially a function used for hair styling purposes, such as a function of directly contacting the hair (combing, straightening, etc.).

[0023] For the sake of simplicity, this specification mainly focuses on the hairdressing device 1 ( Figures 1 to 5 ) and a hairdressing device 1'( Figures 6 to 10 ). Unless otherwise indicated, the technical features associated with the hairdressing device of the first embodiment are preferably interchangeable with the technical features associated with the hairdressing device of the second embodiment (and vice versa) with necessary modifications. The same or similar parts between the two embodiments shown in the drawings are marked with the same reference numerals in this specification.

[0024] The hairdressing device 1, 1' according to the present invention comprises a handle 2 (or grip) for manual gripping, which is used for the user to grip and thus operate the hairdressing device 1, 1'. The handle 2 extends between a first end 3 and an opposite second end 4, preferably the second end 4 is in the length direction of the first central axis A-A'. In the embodiment shown in the figure, the handle 2 is formed as one piece - or assembled as one piece - and is generally tubular (for example, the middle cross section is circular or oval, continuous or discontinuous), and the size is adjusted and the handle 2 is suitable to ensure that the user can grasp it well with his hand.

[0025] The hairdressing device 1, 1' also includes an embedded air supply module 5 for generating (strong) airflow, and an air supply head 6 extending from a handle 6, and the airflow generated by the air supply module 5 is guided to the outside of the hairdressing device 1, 1' through the air supply head 6, so that the airflow can be directly sprayed onto the user's hair.

[0026] More specifically, the air supply head 6 has at least one first air outlet 7 and one second air outlet 8 which are separated from each other (different from each other and do not overlap). Preferably, the air supply head 6 is configured to be rotatable between at least one first position and one second position relative to the handle 2, the air flow blown out of the air supply head 6 is blown out from the first air outlet 7 in the first position, and the air flow blown out of the air supply head 6 is blown out from the second air outlet 8 in the second position, and the above components form a unified subassembly. On the other hand, the air supply head 6 is relatively arranged on the handle 2 through a connecting shaft so that it can be rotated relative to the handle. At the same time, the hairdressing device 1, 1' according to the present invention is designed and configured to allow the user to select the air flow blown out of the air supply head 6 from one of the first air outlet 7 and the second air outlet 8 by rotating the air supply head 6 relative to the handle 2. Preferably, the air supply head 6 is designed to be permanently connected to the handle 2 of the hairdressing device 1, 1', and the user (under normal use) cannot separate the air supply head 6 from the handle 2 of the hairdressing device 1, 1'.

[0027] According to the present invention, the first air outlet 7 and the second air outlet 8 have openings with different geometric shapes. In addition, the effective cross-section of the air outlet channel of the first air outlet 7 is determined by one (or more) contours, and the shape of the contour is different from the one (or more) contours that determine the corresponding effective cross-section of the air outlet channel of the second air outlet 8. Therefore, the airflow blown out from the air supply port 6 has different airflow contours depending on the selected air outlet 7 or 8, thereby enabling the user to use the hairdressing device 1, 1' according to at least two different blowing shapes. Accordingly, the first air outlet 7 and the second air outlet 8 are preferably configured to blow out or spray out two airflows with different contours, namely the first airflow and the second airflow, and any one of the airflows can ensure that the user can perform different operations on the hair. For example, the first airflow may correspond to a relatively wide and dispersed contour with a large flow rate (for example, set to 70m 3 / h) of the first drying airflow to ensure that the user can quickly dry the hair. The second airflow may correspond to a relatively concentrated and narrow profile with a relatively small flow rate (e.g., 50m / h). 3 / h) of the second dry airflow, ensuring that the user can accurately select the part of the hair on which the second airflow blows. In this way, the user can cleverly and simply achieve the styling of the hair, such as wavy styling, or conversely, straightening the hair.

[0028] For example, in Figures 1 to 5 In the first embodiment shown, the hairdressing device 1 is formed as a hair dryer, and the first air outlet 7 has a substantially circular opening ( Figure 2 ), while the second air outlet 8 ( Figure 1 and 3) has a roughly stretched elliptical opening. Based on this, when the air supply head 6 is located at the first position relative to the handle 2, the hairdressing device 1 can dry wet hair in a traditional way, and the first airflow blown out by the air supply head 6 is formed near the first air outlet 7, and the outline is roughly cylindrical or conical. When the air supply head 6 is located at the second position relative to the handle 2, the hairdressing device 1 can not only dry hair but also easily style hair (for example, combing hair), and the air wave formed by the second airflow blown out from the air supply head 6 near the second air outlet 8 allows the user to accurately select the hair area to be processed, and the airflow can also be used to achieve hair styling operations.

[0029] According to the illustrated method but not limited to this method, the opening of the first air outlet 7 is preferably capable of generating a first drying airflow, and the opening has a first air channel effective cross-section, which is preferably 707 mm 2 Up to 1963mm 2 , for example, equal to 962mm 2 (The corresponding opening is a circular first air outlet, which preferably has a diameter of 30 to 50 mm, most preferably 35 mm). The opening of the second air outlet 8 preferably has a second air channel effective cross-section, and air flows in a channel corresponding to the first air channel effective cross-section of the first air outlet 7. For example, the second air channel effective cross-section is 240 mm 2 Up to 640mm 2 , for example, equal to 360mm 2 (The corresponding opening of the 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 a length of about 60 mm and a width of about 6 mm).

[0030] exist Figures 6 to 10 In the second embodiment shown, the hairdressing device 1' is formed as a hair-drying comb, and the first air outlet 7 may have a substantially stretched elliptical opening ( Figure 7 ), as for the second air outlet 8 ( Figure 6 and 8 ), the openings of which are formed by a large number of holes distributed between the rows of combing hairs (or hairpins) of the comb, and these holes are generally circular. In this way, when the air supply head 6 is located at the first position relative to the handle 2, the hairdressing device 1' can achieve, for example, a pre-drying operation of the hair using a first airflow with a wide and dispersed but large flow rate. When the air supply head 6 is located at the second position relative to the handle 2, the hairdressing device 1' can achieve, for example, a final drying operation using a second airflow with a more concentrated but relatively small flow rate blown out from between the combing hairs (or hairpins) of the comb.

[0031] Accordingly, the hairdressing device 1, 1' according to the present invention can preferably be selected by the user between at least one first usage mode (e.g. hair drying) and a second usage mode (e.g. hair styling) by simply rotating the air supply head 6 relative to the handle 2. This method can particularly simply and quickly adjust the air flow profile according to different operations on the hair.

[0032] It is foreseeable that the first and second air outlets are assembled to each other in the form of detachable (e.g. by snaps, screws, press-fitting, etc.) parts at other positions of the air supply head that can be rotated relative to the handle (variations are not shown in the figures), which does not exceed the scope of the present invention. In fact, this ensures that the user can equip the hairdressing device 1, 1' with two separate air outlets with different cross-section shapes (rather than only one air outlet, as in the case of traditional hair drying instruments), and also ensures that the user can use these air outlets continuously without the need to remove / reinstall parts, while still retaining the option of replacing one or another part, and choosing these accessories according to the specific use of the hairdressing device desired by the user.

[0033] Advantageously, however, the blowing head 6 forms, on the contrary, a coherent assembly, not intended to be disassembled by the user, the first air outlet 7 and the second air outlet 8 being constituted by one or more non-detachable parts belonging to the blowing head 6 (in normal use conditions). Thus, by displacing, the position of the blowing head 6 relative to the handle 2 of the device 1, 1' is changed (preferably by rotation), and the user can very significantly select one or the other of the first air outlet 7 or the second air outlet 8, and thus advantageously select his desired air flow curve, without having to mount or dismount any accessories of the hairdressing device 1, 1'. Thus, the user benefits from an easy and quick use of the device 1, 1' and is assured that no element of the device will be lost.

[0034] More specifically, the air supply head 6 is rotatably mounted relative to the handle 2 about a second axis BB', which preferably coincides with the first axis A-A' extending from the handle 2, as shown in the embodiment shown in the accompanying drawings. In addition, the second rotation axis BB' can also be parallel to the first axis A-A' (and can be more or less offset relative to the first axis A-A'). Therefore, the kinematic principle of the air supply head 6 is simple and reliable, and allows the user to intuitively operate the hairdressing device 1. Alternatively, the second axis BB' intersects the first axis A-A' at an angle generally between 5° and 15°.

[0035] In order to make the hairdressing device 1, 1' easy to use in all cases, in particular for treating the hair at the back of the user's head, the first air outlet 7 and the second air outlet 8 are preferably arranged so that the airflow generated by the air supply module 5 is blown out by the air supply head 6 in a direction intersecting the extension direction of the first axis A-A', preferably in a substantially orthogonal direction. Particularly preferably, the hairdressing device 1, 1' is designed and constructed so that the air supply head 6 blows the airflow in substantially the same direction, regardless of whether the air supply head 6 is in the first position or the second position relative to the handle 2. Therefore, the user can selectively use the first and second positions of the air supply head 6 of the hairdressing device 1, 1' without adjusting its manual grip position on the handle 2 or changing the overall spatial position of the hairdressing device 1, 1'.

[0036] In the embodiment shown in the figure, the conversion of the air supply head 6 from the first position to the second position is preferably performed by rotating the air supply head 6 180° around the second axis BB'. In other words, the air supply head 6 of the hairdressing device 1, 1' is designed and constructed so that the first air outlet 7 and the second air outlet 8 of the air supply head 6 are arranged on both sides of the second axis BB' of the rotation of the air supply head 6 relative to the handle. This layout helps the user to operate the hairdressing device 1, 1' simply and intuitively.

[0037] Preferably, the first and second positions of the air supply head 6 are stable positions, and the air supply head 6 cannot be dislocated in an unexpected manner without active operation by the user. In this case, the hairdressing device 1, 1' preferably includes a device (not shown) for fixing the air supply head 6 in the first and second positions relative to the handle 2, such as a pair of magnets, a "cooking bowl (culs de poule)" or any other known suitable method.

[0038] It should be noted that it is understood that the present invention is not limited to an air supply head 6 comprising only two air outlets 7, 8, in particular, the air supply head is rotatable relative to the handle 2 and the air outlets are only arranged at 180° relative to the second axis BB', although this assumption is retained in the preferred embodiment shown in the drawings. In fact, the air supply head 6 can completely include more air outlets separated from each other and having different geometric cross-sections (for example 3 or 4), which the user can select by rotating relative to the handle and blowing the head in different corresponding positions.

[0039] Preferably, the three or four (or more) air outlets are regularly distributed around the second rotation axis BB' in a sector of equal angles according to the number of the air outlets. Thus, for example, it is conceivable to provide three independent air outlets, and the three air outlets are separated from each other and have cross-sections of different geometric shapes, and the air outlets are provided so that the air supply head can be switched from a first position to a second position, and then from the second position to a third position, for example, corresponding to a manner in which the air supply head rotates 120° around the second axis BB'. For example, it is also conceivable to provide four independent air outlets, which are separated from each other in position and have cross-sections of different geometric shapes, so that the air supply head is switched from a certain position to another position, for example, corresponding to a manner in which the air supply head rotates 90° around the second axis BB'. In addition, the rotation of the air supply head around the second axis BB' to switch the air outlet from a given position to another position can obviously result in different rotation angles depending on the total number of positions / air outlets and the 360° ratio.

[0040] The air supply module 5 of the hairdressing device 1, 1' preferably comprises an electric fan unit 10, which itself comprises an electric motor 11. The electric fan unit 10 may comprise a conventional axial flow fan having a spiral shape. Alternatively, the electric fan unit 10 preferably comprises a spiral centrifugal or centrifugal fan. In an embodiment using such a spiral centrifugal or centrifugal fan, a higher internal pressure can be obtained with the same fan size, the air flow of which is substantially similar to that of a spiral fan, but such a fan has a lower rotation speed, so that the electric fan unit 10 generates less noise. 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 a brushless motor is generally more robust and lightweight than a conventional brushed motor. It is less noisy, more energy-efficient, and can also provide greater flexibility and higher precision when adjusting the rotation speed.

[0041] The air supply module 5 can be placed inside the handle 2 or inside the air supply head 6. However, more preferably, as shown in the embodiment in the figure, the air supply module 5 of the hairdressing device 1 is assembled on the first end 3 of the handle 2, and the air supply head 6 is rotatably mounted at the second end 4 of the handle 2 relative to the handle 2. In this way, the air supply head 6 extends from the second end 4 of the handle 2, and 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 of the handle 2, so that the air supply module 5 has no possibility of rotating relative to the handle 2. In addition, the air supply module 5 itself can lead out a power cord 9, for example Figures 6 to 10As shown. Therefore, the air supply module 5 of the hairdressing device 1, 1' is preferably far away from the air supply head 6 and the handle 2 for holding the hairdressing device 1, 1'. The size of the air supply module 5 can be determined accordingly so as to economically generate a large amount of air flow without affecting the overall size of the air supply head 6 and the handle 2. In addition, by distributing the mass on the other side of the handle 2, this arrangement of the air supply module 5 is conducive to better balancing the weight of the hairdressing device 1, which contributes to the comfort of use.

[0042] In the case where the air supply module 5 is arranged inside the handle 2 or assembled at the first end 3 of the handle 2, the handle 2 may preferably include a guide channel 12 for guiding the airflow generated by the air supply module 5 and transmitted in the direction of the air supply head. Preferably, the guide channel 12 guides the airflow through the handle 2, along the direction of the first end 3 of the handle 2 toward the second end 4. The hairdressing device 1, 1' may also preferably include a guide plate 13, which is designed and configured to guide the airflow generated by the air supply module 5 from the guide channel 12 of the handle 2 toward the first air outlet of the first handle when the air supply head 6 is in the first position. Vice versa, when the air supply head 6 is in the second position, it is guided toward the second air outlet 8.

[0043] exist Figures 1 to 5 In the first embodiment shown, the electric fan unit 10 preferably comprises a centrifugal fan 14, and the air supply module 5 comprises a working chamber 15 in the form of a volute, in which the electric fan unit 10 is placed. Figure 5 As shown, it can be defined by the inner walls of two half shells 16 and 17 assembled together (for example, fixed by bolts), and fixed on the first end 3 of the handle. The air supply module 5 has an air inlet 18, and the fan 14 draws ambient air into the working chamber 15 axially from the air inlet 18. At the same time, preferably, the air outlet is connected to the guide channel 12 of the handle 2, and the inhaled air is radially pressed into the guide channel 12 from outside the working chamber 15. The air supply module 5 also preferably includes a grille (removable and repositionable when necessary) for protecting the air inlet 18 of the working chamber 15. In particular, as Figure 5 As shown, the air intake module 5 is preferably designed and constructed so that the axis of the centrifugal fan 14 of the electric fan unit 10 is substantially orthogonal to the first axis A-A' in the extension direction of the handle 2. The air inlet 18 of the working chamber 15 is preferably arranged to suck in ambient air in a direction substantially parallel to the direction of the air flow blown out by the air supply head 6, and more preferably in the same direction. Of course, it is conceivable that, without departing from the scope of the present invention, the ambient air is sucked into the working chamber 15 along the secant direction (for example, substantially perpendicular to the average direction of the air flow blown out by the air supply head 6).

[0044] for Figures 6 to 10In the second embodiment shown, in which the hairdressing device 1 is formed as a hairbrush, the electric fan unit 10 preferably comprises a spiral fan 14. The air supply module 5 is connected to the first end 3 of the handle 2, and the air supply module 15 comprises a working chamber 15 with a substantially cylindrical inner wall, and the electric fan unit 10 is accommodated in the working chamber 15. The electric fan unit 10 is arranged so that the axis of the spiral fan 14 is parallel to, and preferably coincides with, the first axis A-A' extending in the longitudinal direction of the handle 2. The air supply module 5 is provided with an air inlet 18, which can be a grille, for example, and the fan 14 sucks ambient air into the working chamber 15 axially from the air inlet 18, and preferably, the air outlet is connected to the guide channel 12 of the handle 2, and the sucked air is radially pressed into the guide channel 12 from outside the working chamber 15. This arrangement is conducive to limiting the radial size of the hairdressing device 1' determined by the handle 2 and the air supply module 5.

[0045] Preferably, the air supply head 6 comprises a housing 20, which defines the shape and profile of the air supply head 6, and advantageously defines the shape and profile of the end of the hairdressing device 1, 1' extending from its handle 2. Preferably, the shape of the housing 20 is designed to allow the user to manually grasp it, so that the user can directly apply pressure to the housing 20 (i.e., the air supply head 6) by hand to rotate the air supply head 6 relative to the handle 2 around the second axis BB', so as to select one of the first air outlet 7 and the second air outlet 8 of the air supply head, and then select the corresponding operation mode of the hairdressing device 1, 1'.

[0046] Preferably, the air supply head 6 comprises a nozzle body 19, and the nozzle body 19 is used to direct the air blown out by the hairdressing device 1 toward 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 fairing), which can be formed, for example, by half shells fastened by snaps or assembled by screws. The housing 20 of the air supply head 6 is rotated by the user around the second axis BB', which causes the nozzle body 19 to also rotate around the second axis BB'. The housing 20 can be formed to give the air supply head 6 a special aesthetic appearance, for example Figures 1 to 5 The roughly cylindrical appearance shown.

[0047] Preferably, the housing 20 of the air supply head 6 extends longitudinally substantially along the third axis CC', which is orthogonal to the middle plane of the air supply head 6, and the air supply head 6 is arranged relative to the handle 2 so that the second rotation axis BB' of the air supply head 6 coincides with the first axis A-A' extending longitudinally along the handle 2, and so that the first axis A-A' and the second axis B-B' are located in the middle plane of the air supply head 6. In this way, the housing 20 preferably extends along the third axis CC', which is orthogonal to the first axis A-A' extending longitudinally along the handle and the second axis B-B' about which the air supply head 6 rotates, and has a substantially equal distance from the first A-A' axis and the second axis B-B'.

[0048] Apart from the symmetrical or quasi-symmetrical aesthetic effect that can be achieved thereby, this particular arrangement provides in particular a good overall balance and contributes to good maneuverability for the user.

[0049] In particular, if Figure 5 As shown in the cross-sectional view, the nozzle body 19 preferably extends as a whole along the third axis CC' extending 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 roughly 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 roughly elongated oblong opening in a direction perpendicular to the second axis BB').

[0050] In this specific first embodiment, the hairdressing device 1 further comprises a guide plate 13, which, as mentioned above, guides the airflow generated by the air supply 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 according to the position of the air supply head 6. Figure 5 As shown, the deflector 13 preferably includes an elbow 21, which is relatively fixedly mounted on the handle 3 and extends the guide channel 12 of the handle 2 in the direction of the first axis A-A' of the handle 2. Therefore, the air supply head 6 preferably rotates around the elbow 21 of the deflector 13 to transfer it between the first and second positions.

[0051] As a particularly preferred embodiment, the elbow 21 and the handle 2 form an integral structure ( Figure 5 ), which can significantly reduce the number of parts of the hairdressing device 1 and facilitate manufacturing.

[0052] like Figure 5As shown, the nozzle body 19 preferably includes an air inlet hole 22, which has a size that matches the elbow 21 of the guide plate, and with the help of the air inlet hole, the elbow 21 passes through the nozzle body 19 in the direction of the second axis BB' around which the air supply head 6 rotates. The elbow 21 and the nozzle body 19 are arranged according to each other as follows: when the air supply head 6 is in the first position, the elbow 21 guides the air flow in the nozzle body 19 to the first nozzle body end that constitutes the first air outlet 7 of the air supply head 6, and preferably prevents air from leaking from the direction of the second nozzle body end on the opposite side. Vice versa, the elbow 21 and the nozzle body 19 are arranged according to each other as follows: (after rotating the rotating air supply head 6 180° around the second axis BB') when the air supply head 6 is in the second position, the elbow 21 guides the air flow in the nozzle body 19 to the second nozzle body end that constitutes the second air outlet 8 of the air supply head 6, and preferably prevents air from leaking from the direction of the first nozzle body end on the opposite side ( Figure 5 As shown in the figure, the guide plate 13 (especially the elbow 21 thereof) and the nozzle body 19 are configured to guide the airflow in the guide channel 12 of the handle 2 in a manner of deflecting 90° toward the direction of either the first air outlet 7 or the second air outlet 8.

[0053] Obviously, it is foreseeable that the air supply head 6 of the hairdressing device 1 has different designs, for example Figures 6 to 10 The design shown relates to a second preferred embodiment of a hairdressing device 1 , 1 ′ according to the invention.

[0054] Figures 7 to 10 The hairdressing device 1' shown in the figure is formed as a hair-drying comb, and the air supply head 6 preferably has an appearance roughly similar to a conventional hair comb. In this case, the air supply head 6 extends along a fourth axis D-D', which is parallel to, and preferably coincides with, a second axis BB' along which the air supply head 6 rotates relative to the handle 2. In addition, as shown in the figure, the air supply head 6 is arranged relative to the handle 2 so that the second rotation axis BB' of the air supply head 6 coincides with the first axis AA' extending in the longitudinal direction of the handle 2.

[0055] If especially in Fig.10 As shown in , the air supply head 6 may include a nozzle body 19, which is not installed in the housing 20 of the air supply head 6 in the form of a separate component at this time, but the nozzle body 19 is directly defined by the inner wall of the housing 20. The housing 20 can be composed of a plurality of shell-shaped elements assembled together in a manner similar to the first embodiment (for example, fixed by snaps or screws). Then, the nozzle body 19 preferably extends along a fifth axis EE', which is orthogonal to the fourth longitudinal axis D-D' in the air supply head 6. On the one hand, the first nozzle body end constitutes the first air outlet 7 of the air supply head 6, and on the other hand, the second nozzle body end on the opposite side constitutes the second air outlet 8 of the air supply head 6.

[0056] According to another embodiment, the housing 20 may include at least one column (not shown) arranged at the edge of the housing 20, which is arranged to contact the hair during the hair styling operation. The column is preferably heatable, or at least capable of transferring the heat of the dry air flow flowing in the air supply head 6 to the hair. For example, the column can be made of a heat-conducting material, such as a metal material (steel, aluminum, etc.), and is in direct contact with the dry air flow flowing inside the nozzle body 19. For example, the column can pass through the entire housing 20, one side extending into the interior of the nozzle body 19 so as to contact the dry air flow, and the other side extending to the outside to contact the hair. The protruding edge of such a column can contact the hair during styling, preferably heating the edge, which gives the hair a ribbon-like effect. Through this protruding effect, a bunch of hair can be formed into a coordinated wave, just like the waves produced by rubbing a ribbon with a blade when we prepare exquisite gift packaging. Preferably, the housing includes two columns that are opposite to each other, substantially parallel, and arranged on either side of the fourth axis D-D', so that people with any experience in operating hairdressing equipment can achieve a ribbon-like (bolduc) hair effect.

[0057] The first air outlet 7 of the air supply head 6 has a substantially stretched elliptical opening, which is substantially parallel to the direction of the fourth axis DD' extending longitudinally of the air supply head 6 ( Figure 7 The second air outlet 8 of the air supply head 6 may be composed of a plurality of holes distributed between rows of combing hairs (or hair pins), and these holes are usually circular ( Figure 6 and 8 ).

[0058] In this second specific embodiment, the hairdressing device 1' also includes a deflector 13, which guides the airflow generated by the air supply 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 according to the position of the air supply head. Figure 5 As shown, the deflector 13 preferably includes an elbow 21, which is formed as a closed conical section, and its inner side wall is provided with an axial opening. The elbow 21 fixed relative to the handle 2 extends along the first axis AA' and extends the air guide channel 12 of the handle 2 and extends out of the second end 3.

[0059] like Figure 5 As shown, the nozzle body 19 preferably includes an air inlet hole, the size of which matches the size of the elbow 21 of the guide plate 13, and by means of the air inlet hole, the elbow 21 can pass through the nozzle body 19 along the second axis BB' around which the blowing head 6 rotates. Figures 6 to 10 The corresponding configuration and arrangement of the elbow pipe 21 and the nozzle body 19 in the second embodiment are the same as those according to Figures 1 to 5In the first embodiment, the configuration and arrangement of the elbow 21 and the nozzle body 19 are similar, or even identical, and can produce substantially the same effect.

[0060] 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 guide plates, more or less inclined and preferably fixedly mounted, so designed and configured to even out the velocity / flow distribution of the air flow profile blowing out of the air outlet when necessary. For example, in the embodiment shown in the drawings, the opening of the first air outlet 7 is provided with a wing guide plate 23, which, combined with the geometric shape of its opening, can be suitable for the use of the hairdressing device 1, 1' for drying / pre-drying purposes. Figures 1 to 5 In the first embodiment, the wing guide plate 23 is preferably formed integrally with the nozzle body 19. Alternatively, the wing guide plate 23 is a separate additional component, such as Figures 6 to 10 Preferably, the geometric shape of the opening of the second air outlet 8 is adapted to the use of the hairdressing device 1, 1' for the purpose of hair styling or auxiliary styling, which itself is not equipped with a wing guide plate.

[0061] Preferably, the hairdressing device 1, 1' further comprises a heating element 24 for heating the airflow generated by the air supply module 5. The heating element 24 embedded in the hairdressing device 1, 1' can be accommodated in the air supply head 6 or in the handle 2 (i.e., inside). Preferably, the heating element 24 is (at least partially) accommodated in the handle 2 (i.e., inside), and more preferably, as shown in the embodiment of the drawings, it is arranged in the guide channel of the handle 2 in a manner of being placed between the airflows generated by the air supply module 5. This configuration can significantly reduce the size and weight of the air supply head 6 while simplifying the design. The electric heating element is generally an element that works according to the Joule effect principle, and the power is preferably greater than 500W. Preferably, the heating element 24 comprises at least one heating resistor obtained by winding an insulating core with a conductive metal wire (e.g., a nickel-chromium alloy). In the preferred embodiment shown in the drawings, the heating element 24 is more precisely composed of a metal wire (not shown) wound around an insulating core 25 (e.g., made of mica) with a cross-shaped cross section, and fixed fins are provided at its ends. Preferably, the hairdressing device 1, 1' further comprises a heat insulator 26, for example a tubular component with a circular bottom surface, in which the heating element 24 is arranged, which protects the user from being burned by limiting the heating of the handle 2. As shown in the figure, the inner wall of the heat insulator 26 preferably constitutes all or part of the aforementioned guide channel 12.

[0062] Preferably, the hairdressing device 1, 1' further comprises an electronic module 27. This module does not require the user to operate or contact it, and the electronic module 27 is preferably designed to interact (directly or indirectly) with all or part of the components constituting the hairdressing device 1. It is usually a circuit board, an electronic circuit, a printed circuit ("PCB") or a set of electrical, electronic or electromechanical components inside the hairdressing device 1, 1'. The electronic module 27 is used to ensure a specific power supply mode (for example, with current filtering, conversion or rectification functions) to ensure the control, command or even regulation of one and / or another functional component of the hairdressing device 1, 1'. Optionally, the electronic module 27 may include components such as a battery, a display, one or more microcontrollers, etc. The electronic module 27 can also be optionally connected to a certain number of sensors and inductive elements distributed in the hairdressing device 1, 1', so as to measure and monitor physical parameters related to the functions of the hairdressing device 1, 1' (temperature, voltage and current, air flow rate / flow, rotation speed of the fan 14 of the air supply module 5, etc.), so as to better control the operation of various functional components of the hairdressing device 1, 1'.

[0063] In a more preferred embodiment, the electronic module 27 is designed as an electronic module for controlling the air supply module 5 and / or the heating element 24 of the hairdressing device 1, 1'. In fact, in order to control the air supply module 5 and / or the heating element 24 of the hairdressing device 1, 1' respectively according to the adopted technology, it is necessary to implement specific control on one (or more) electronic modules or electronic circuits.

[0064] For example, when the electronic module 27 is designed to control the heating element 24, the electronic module 27 may include an electrical supply and / or specific regulation (power, temperature, etc.) circuit for controlling the electronic module. As mentioned above, in the preferred case where the air supply module 2 includes a brushless motor 11, the 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 winding according to the position sensor data (such as Hall effect) (phase control), ensure autonomous regulation of the speed, etc.

[0065] Preferably, if Figures 1 to 5 In the first preferred embodiment shown, such an electronic module 27 is preferably arranged inside the air supply head 6, preferably outside the air flow inside the air supply head 6. Preferably, the air supply head 6 comprises a dedicated compartment 28 for accommodating said electronic module 27.

[0066] This arrangement helps to limit the overall size of the hairdressing device 1, 1', especially when the electronic module 27 is designed to control the air supply module 5 and / or the heating element 24, and the heating element is arranged outside the air supply head 6. As mentioned above, when the heating element 24 is arranged inside the handle 2 and / or the air supply module 5 is installed inside the handle 2 or at one end of the handle 2, the electronic module 27 is preferably arranged separately from the heating element 24 and / or the air supply module 5 controlled by it, which can minimize the overall size of the handle 2 and / or the air supply module 5 connected thereto.

[0067] However, considering the rotational characteristics of the air supply head 6, it may be difficult to ensure a simple and secure electrical connection when, on the one hand, the heating element 24 and / or the air supply module 5 are outside the air supply head 6 (or any other functional component of the hairdressing device 1, 1' that may be connected to the electronic module 27 and arranged outside the air supply head 6), and on the other hand, the electronic module is arranged inside the air supply head.

[0068] That's why in Figures 1 to 5 In the first preferred embodiment shown, the electronic module 27 is preferably installed inside the air supply head 6 so as to remain relatively stationary with the air supply module 5 and / or the heating element 24 outside the air supply head 6. In this case, Figure 5 As shown, the nozzle body 19 may be provided with an auxiliary hole 29, which is opposite to the air inlet hole, and the elbow 21 of the deflector 13 passes through the nozzle body 19 via the auxiliary hole 29. The height of the auxiliary hole 29 is flush with the nozzle body 19 or a part of it exceeds the nozzle body 19, so that the electronic module 27 can be directly or indirectly fixed on the elbow 21 through the support member 30. Obviously, other suitable installation methods can be foreseen. For example, according to the size, the electronic module 27 can be installed on the back of the elbow 21 of the deflector 13.

[0069] Thus, the electrical connection between the heating element 24 and / or the air supply module 5 and the electronic module 27 arranged in the air supply head 6 can be realized very simply using, for example, conventional conductive wires (not shown), i.e., there is no risk of damaging the wires due to twisting, and there is no need to use a complex mobile electrical connection device (e.g., a connector type of rotational connection). Therefore, the manufacturing cost of the hairdressing device 1 can be reduced and the reliability can be improved.

[0070] Although the electronic module 27 is arranged inside the air supply head 6, and preferably outside the air flow passing through the air supply head 6, the temperature of the electronic module 27 is likely to increase significantly if the air flow generated by the air supply module 5 is heated by the heating element 24 before being blown out of the device 1 by the air supply head 6. In addition, even if the heating element 24 is not started or the device is not equipped with such a heating element, the electronic module 27 is likely to heat itself under the action of the current under normal operation. 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 or even the entire device will increase in any case.

[0071] To this end, the hairdressing device 1, 1' may particularly preferably include a diverter channel 31, which is used to capture part of the airflow generated by the air supply module 5, thereby ensuring the cooling of the electronic module 27. In order to ensure forced cooling of the electronic module 27, this part of the airflow is guided and blown as close to the electronic module 5 as possible, so the diverter channel 31 is designed and constructed to collect and divert part of the forced airflow generated by the air supply module 5 before the heating element 24 heats the airflow when necessary.

[0072] When the air supply module 5 is arranged in the handle 2 or at the first end 3 of the handle 2, the diverter channel 31 preferably extends at least partially in the handle 2. Therefore, the diverter channel 31 is preferably integrated in the handle 2. As a more preferred embodiment, the hairdressing device 1, 1' can be arranged so that the guide channel 12 and the diverter channel 31 extend in parallel with each other in the handle, preferably along the first axis A-A' of the handle.

[0073] For example, in Figures 1 to 5 In the first preferred embodiment shown, on the one hand, the diversion channel 31 is opened at the air outlet of the working chamber 15 of the air supply module 5, so as to capture part of the air flow generated by the air supply module 5 (cold air, i.e., air that has not yet been heated by the heating element 24); on the other hand, it is directly adjacent to the electronic module 27 arranged in the air supply head 6.

[0074] like Figure 5 In the embodiment shown, the diverter channel 31 may occupy the free space formed between the inner wall of the handle 2 and the outer wall of the thermal insulator 26 in the longitudinal direction of the handle 2 in whole or in part. This arrangement also facilitates cooling of the handle 2, which improves the comfort of use of the hairdressing device 1, 1 '. The diverter channel 31 may also preferably extend between the double wall 32 formed by the back of the elbow 21 at the height of the air supply head 6, and then pass through the support 30, through which the electronic module 27 is fixed to the elbow 21 as described above.

[0075] Preferably, the hairdressing device 1, 1' may further include a circuit for re-ejecting a portion of the airflow captured in the (main) airflow blown out by the air supply head 6, so that the portion of the airflow captured by the diversion channel 31 and allocated to the electronic module 27 for cooling can be directly blown to the user's hair through the air outlets 7 and 8 on the air supply head. In this way, the cooling of the electronic module 27 will not substantially affect the flow rate of the airflow generated by the air supply module 5 and blown out from the air supply head 6. For example, the air nozzle body 19 of the air supply head 6 may be provided with a hole (not shown) for re-ejecting a portion of the airflow collected directly inside the air nozzle body 19, preferably arranged downstream of the elbow 21 of the guide plate 13.

[0076] Alternatively (or supplementally), the housing 20 of the air supply head 6 may be provided with air holes (or equivalent structures), through which all or part of the captured airflow can escape from the air supply head 6, that is, escape from the hairdressing device 1, 1 '. In this way, the part of the airflow used to cool the electronic module 27 is discharged from the hairdressing device 1, 1 ' without affecting (or at least not significantly affecting) the temperature of the (main) airflow that blows directly from the air supply head 6 to the user's hair.

[0077] Typically, the size of the diversion channel 31 is determined to allow the air flow therein to be 1 to 10 m / s. 3 / h of flow rate, so that the electronic module 27 is effectively cooled.

[0078] According to a variation of the embodiment shown in the drawings, the hairdressing device 1, 1' includes a manual adjustment device 33 for the user to operate, which is used to adjust the air supply module 5 and / or the heating element 24. The adjustment device involves a type of adjustment device such as a toggle switch, a key switch and / or a sliding switch or a knob switch, through which the user can directly operate to turn on / off the hairdressing device 1, 1' and adjust the rotation speed of the fan 14 of the air supply module 5, thereby adjusting the speed / flow rate of the air flow blown out by the air supply head 6 and / or the heating temperature of the heating element 24. The position of such a known manual adjustment device can be, for example, set on the handle 2 or on the air supply module 5. For the latter position, it can be assembled on the first end 3 of the air supply module as shown in the figure.

[0079] According to another variant (not shown), the hairdressing device 1, 1' may include an automatic adjustment device for adjusting the operation of the air supply module 5 and / or the heating element 24, which automatically controls the air supply module 5 and / or the heating element 24 according to 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 realized by the rotation of the air supply head 6 relative to the handle 2. Therefore, the automatic adjustment device (if necessary through the above-mentioned electronic module 27) cooperates with the air supply module 5 and the heating element 24, so as to automatically adjust the position of the air supply head 4 relative to the handle 2 according to the user.

[0080] Such an automatic adjustment device can also be obtained by any other known means using the automatic control function. For example, the automatic adjustment device can specifically include one or more switches or contactors (electrical, 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 supply head 6 relative to the handle 2. They are usually arranged at the interface between the air supply head 6 and the handle 2, and are electrically connected to the air supply module 5 and / or the heating element 24 (if necessary, through the aforementioned electronic module 27), and the automatic adjustment device can be started or stopped according to the position of the air supply head 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 be preferably preset according to the first and second positions of the air supply head 6, and preferably, the air supply module and / or the heating element correspond to different preset functions at the same time.

[0081] The automatic adjustment device may preferably be designed and configured so that the first position of the air supply head 6 corresponds to the first speed F1 and the first temperature T1 of the air flow 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 may preferably be designed and configured so that the second position of the air supply head 6 corresponds to the second speed F2 and the second temperature T2 of the air flow blown out by the air supply head 6 (i.e., through the second air outlet 8 of the air supply head 6).

[0082] In a more preferred embodiment, the first speed F1 and the second speed F2 of the airflow blown out by the air supply head 6 are different from each other, and the first temperature T1 and the second temperature T2 of the airflow blown out by the air supply head 6 may also be different from each other. However, it is foreseeable that the automatic adjustment device can be configured to cooperate with the air supply module 5 and the heating element 24, so that the airflow can be automatically blown out at the same speed or temperature regardless of the position of the air supply head 6, and thus regardless of the selected air outlet 7 or 8, and the opening shape of the air outlet 7 or 8.

[0083] In this way, any of the first and second positions of the air supply head 6 can be automatically paired with the speed-temperature of the blown air flow, and this pairing can preferably be preset and optimized according to the specific use of the hairdressing device 1, 1'. For the purpose of drying hair using the hairdressing device 1, the first speed F1 and the first temperature T1 of the air flow blown out of the air supply head 6 can preferably be preset and optimized. The first position of the air supply head 6 preferably corresponds to the so-called hair drying position. Similarly, for the purpose of styling hair using the hairdressing device 1, the second speed F2 and the second temperature T2 of the air flow blown out of the air supply head 6 can also preferably be preset and optimized. The second position of the air supply head 6 therefore preferably corresponds to the so-called hair styling (setting) position.

[0084] Here, illustratively and not restrictively, the first temperature T1 of the airflow blown out by the air supply head 6 is preferably between 64 and 104° C., more preferably equal to 84° C. The first speed F1 of the airflow blown out by the air supply head 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 blown out by the air supply head 6 is preferably between 60 and 100° C., more preferably equal to 80° C. The second speed F2 of the airflow blown out by the air supply head 6 is preferably between 78.1 km / h and 208.3 km / h, more preferably equal to 138.9 km / h.

[0085] Preferably, the automatic adjustment device can be designed and configured so that when the air supply head 6 is in the first position, it corresponds to the first power P1 of the heating element 24 and the first speed V1 of the fan 14. In order to achieve the purpose of drying hair with the hairdressing device 1, 1', the first power P1 and the first speed V1 can preferably be preset and optimized.

[0086] In this case, illustratively and not restrictively, the first power P1 of the heating element 24 is preferably between 1000 W and 2000 W, more preferably equal to 1500 W. The first rotation speed V1 of the fan 14 is preferably between 13000 rpm (revolutions / minute) and 17000 rpm, more preferably equal to 15000 rpm. According to the size of the air supply module 5, the first rotation speed V1 of the fan 14 corresponds to the flow rate Q1 of the first airflow blown by the air supply head 6, which is preferably 50 m 3 / h to 90m 3 / h, more preferably equal to 70m 3 / h.

[0087] Similarly, the automatic adjustment device can be designed and configured so that when the air supply head 6 is in the second position, it corresponds to the second power P2 of the heating element 24 and the second speed V2 of the fan 14 of the motor-fan unit 10. In order to achieve the purpose of using the hairdressing device 1 to assist in hair styling, the second power P2 and the second speed V2 can preferably be preset and optimized. In this case, illustratively and not restrictively, the second power P2 of the heating element 24 is preferably between 500W and 1500W, and more preferably equal to 1000W. The speed V2 of the fan 14 is preferably between 14000rpm and 18000rpm, and more preferably equal to 16000rpm. According to the size of the air supply module 5, this second speed V2 of the fan 14 corresponds to the flow rate Q2 of the second airflow blown by the air supply head 6, which is preferably 30m 3 / h to 70m 3 / h, more preferably equal to 50m 3 / h.

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

[0089] Thus, the hairdressing device according to the variant of the invention is simpler and more intuitive for the user, since the operation of the air supply module 5 and / or the heating element 24 can be preset 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 hairdressing device 1, 1', the hairdressing device 1, 1' is set in advance to the best adjustment operation according to the position of the air supply head 6. Therefore, regardless of the hair styling experience, the user of the hairdressing device 1, 1' can greatly optimize the hairdressing result.

[0090] Furthermore, advantageously, the hairdressing device 1, 1' can also be designed so that the air supply 6 can be located in a third position different from the first position and the second position relative to the handle 2, and in the third position, the automatic adjustment device for adjusting the operation of the air supply module 5 and / or the heating element 24 is designed to stop the operation of the hairdressing device 1, 1'. In this way, the operation of the hairdressing device 1, 1' can be stopped by allowing the user to rotate the air supply head 6 without directly acting on any common start / stop switch.

[0091] Preferably, the hairdressing device 1, 1' is designed and constructed so that the third position (or stop position) corresponds to a position of the air supply head 6 relative to the handle 2 between the first position and the second position. For example, in this case, the hairdressing device 1, 1' is designed to convert the air supply head 6 from the first position to the second position by rotating it 180° around the second axis BB', so that the conversion to the third position is very intuitive for the user, which corresponds to the air supply head 6 being rotated 90° around the second axis BB' from one and / or the other of the first and second positions to reach the third position.

[0092] Regardless of whether the device for adjusting the air supply module 5 and / or the heating element 24 is manual or automatic, in addition to the adjustment device, the hairdressing device 1, 1' preferably also includes a manual start / stop device for the heating element 24. In this way, regardless of the position of the air supply head 6 (i.e., whether the air outlet 7 or 8 is selected), and regardless of which operation adjustment mode of the air supply module 5 and / or the heating element 24 is selected, the user can stop the operation of the heating element 24 at any time, so that only cold air (i.e., air that has not been heated by the heating element 24) is blown to the hair.

[0093] For example, such a manual start / stop device of the heating element 24 may be constituted by a conventional electric switch, a rocker switch or a key switch provided at the handle 2 of the hairdressing device 1, 1', which connects the heating element 24 and its power supply circuit. Figures 1 to 5 As shown, the manual start / stop device of the heating element 24 includes a mechanical rocker switch 34, which protrudes from the handle 2 and is mechanically connected to a micro switch contained in the air supply module 5 using a pull rod (not shown) contained in the handle 2, and the micro switch 35 itself is assembled at the first end 3 of the handle. By moving a part of the manual start / stop device of the heating element 24 out in this way, it is possible to gain space inside the handle 2 mainly for arranging the heating element 24.

[0094] In the embodiments shown in the drawings and described above, the hairdressing device 1, 1' is preferably designed to allow the user to switch the air supply head 6 from one position to another position, the user holding the handle 2 of the hairdressing device 1, 1' with one hand and holding the air supply head 6 with the other hand, so as to rotate the air supply head 6 around the rotation axis BB' relative to the handle 2. However, according to variant forms not shown, it is entirely foreseeable that the rotation of the air supply head 6 can be motorized, for example, by means of an electric motor controlled by a switch provided on the handle 2, or simply mechanized, for example, by means of a trigger system and a cam. In this case, the user can rotate the air supply head 6 in a simplified manner while holding the handle 2 with one hand.

[0095] The functions and uses of the hairdressing device 1, 1' are as follows.

[0096] The air supply head 6 of the hairdressing device 1, 1' is initially in a first position relative to the handle 2, and the user grasps the handle 2 of the hairdressing device 1, 1' with one hand and prepares to position it: the first air outlet 7 of the air supply head 6 is directed in the direction of the wet hair. Then, the user activates the manual adjustment device 33 to adjust the operation of the air supply module, and preferably adjusts the heating element of the hairdressing device 1, 1' at the same time, so that the preferably hot air flow is forced to flow or blow through the first air outlet 7 of the air supply head 6 in the direction of the user's hair.

[0097] Then, after using the hairdressing device 1, 1' for a desired time, for example, after the hair reaches a certain degree of drying or pre-drying, the user grabs the air supply head 6 with the other hand and moves it rotationally relative to the handle 2 about the axis BB' so that the air supply head 6 is located in its second position. Then, the air flow is blown out through the second air outlet 8 of the air supply head 6. By operating the hairdressing device 1, 1' so that the second air outlet 8 of the air supply head 6 faces the user's hair, the user can now use the hairdressing device 1, 1' to perform operations such as styling on the hair.
