    HAIRDRESSING APPARATUS HAVING AN ELASTIC GUIDE DEVICE FOR A WICK
    Technical area
    The present invention relates to the field of hairdressing apparatus for achieving curling of the hair, of the “curler” type, and very particularly to such hairdressing apparatus equipped with a steam production system which comprises a liquid reservoir, a wick soaked in liquid and a heating element on which said wick comes into contact.
    In addition, such a hairdressing apparatus comprises a mandrel and a tile, these elements being articulated to form a clamp so as to allow the pinching of a lock of hair to wind it around the mandrel and thus curl it.
    State of the art
    It is known from patent applications WO0167915A2 and EP1894488A1 to use a wick to move the liquid contained in the reservoir of a hair curling device towards a heating element to produce steam. More specifically, the wick, in contact with the liquid contained in the tank, will soak up the liquid, by capillary action, thus allowing the transfer of the liquid from the tank to the heating element. This known solution makes it possible to produce steam, which has the effect of improving and facilitating the styling, the holding and the appearance of the hairstyle, and in particular the curls which can be produced from this type of device. .
    In particular, such an apparatus comprises a reservoir mounted at the end of the looping apparatus which is separated from a heating element by the wick. The wick and the reservoir are mounted movable relative to the heating element to allow the user to choose whether or not he wishes to produce steam during the use of the appliance. When the user wishes to produce steam, he exerts pressure on the tank which has the effect of displacing the latter as well as the wick towards the heating element. The wick is then in contact with the heating element, which has the effect of vaporizing the liquid which it contains at its end and consequently of producing vapor which is then rejected on the hair.
    Such devices generally give satisfaction to their users but nevertheless have certain drawbacks, in particular from the point of view of their durability and reliability. Indeed, as the wick moves, when the user presses on the tank, the wick comes into contact with the heating element. During this contact, the end of the latter, under the effect of the force exerted by the user, but also of the heat, will settle, that is to say deform locally. More specifically, the overall length of the wick will decrease while its diameter will locally increase. This then results, as and when used, poorer contact between the wick and the heating element and therefore poorer steam production. The effectiveness of the looping device is thereby reduced, to the point that steam production may even become impossible if the wick is too tightly packed, too deteriorated and no longer comes into contact with the heating element. This therefore results in a lack of reliability and limited durability of the hairdressing appliance.
    Another drawback of these known devices concerns their maintenance. Indeed, given the presence of heated liquid, which is generally water, tartar tends to form in the wick. The user must then dismantle the latter to descale it, for example by soaking it in an acid solution (vinegar for example). But given the flexibility of the wick, the operation of disassembling and reassembling the wick is particularly tedious and delicate, especially if the wick is worn, that is to say if it has been previously packed, since the latter will then have been deformed, as has been detailed previously. This results for the user, particularly when reassembling the wick after descaling, great difficulties, or even sometimes impossibility of reassembly if the wick is too deformed.
    Summary of the invention
    The present invention aims to overcome the aforementioned drawbacks.
    An objective of the invention is to propose a hairstyling device for curling the hair which is particularly reliable and robust, in particular by avoiding the packing of the wick as and when the curling device is used.
    Another objective of the invention is to propose a hairstyling device for curling the hair which offers the user easy maintenance.
    Another objective of the invention is to propose a hairstyling device for curling the hair, the construction of which is particularly simple, economical and reliable.
    Another objective of the invention is to propose a hairstyling device for curling the hair which produces steam quickly and continuously when the user so desires.
    Another objective of the invention is to propose a hairdressing device which is particularly ergonomic to use.
    Another objective of the invention is to propose a hairstyling device which is particularly simple and intuitive to use.
    The objectives are achieved using a hairstyling device for curling the hair comprising a mandrel, a liquid reservoir, a heating element integrated in the mandrel, a wick communicating with the reservoir so as to be soaked with liquid, said wick extending between a proximal end intended to come into contact with the heating element and a distal end supplied with liquid from the reservoir, and means for guiding the wick configured to allow its displacement from a passive position to a position active in which said wick is in contact with the heating element for creating steam, characterized in that said guiding means comprise an elastic guiding device in contact with the periphery of said wick at the proximal end.
    More specifically, the elastic guide device is designed to be able to deform elastically according to an axial deformation, said axial deformation corresponding substantially to the axis of the wick, that is to say to the direction in which the latter extends. Preferably, said direction corresponds to the axis along which the wick moves between its passive position and its active position. Thus, the elastic guide device maintains the peripheral surface of the wick in a direction perpendicular to the wick. In other words, the proximal end of the wick, which is intended to come into regular contact with the heating element to produce steam, is remarkably maintained and guided in a direction substantially perpendicular to the direction of movement of the wick which makes it possible to limit or even eliminate the phenomenon of tamping of the wick. On the other hand, given the elasticity of the guide device in the axial direction, the wick remains free to move axially, and to compress axially, which in particular makes it possible to optimize its contact with the heating element. In addition, the active position of the device, i.e. the position producing steam, is not constrained by the length of the wick.
    Preferably, electrical means make it possible to activate said heating element which advantageously comprises a vaporization plate against which the wick comes into contact in the active position. According to the hairstyling device which is the subject of the invention, it advantageously comprises a unit for controlling the temperature of the heating element. In addition, a detection system is configured to trigger the control unit when the bit enters the active position.
    Preferably, said elastic guide device is permeable to air in order to allow the reservoir to be vented, and this in order to compensate for the depression linked to the emptying of the liquid from the reservoir through the wick.
    Advantageously, said elastic guide device comprises a helical spring and said wick is arranged inside said spring, which makes it possible to propose a simple, robust and economical assembly.
    Advantageously, the diameter of the spring is between 2 mm and 8 mm and preferably between 4 mm and 6 mm. The length at rest of the spring is between 15 mm and 45 mm and preferably between 25 mm and 35 mm.
    In addition, said guide means comprise a wick holder inside which said helical spring is arranged. Such an arrangement makes it possible to have a particularly precise, robust and reliable guide device for the drill bit, while allowing air to pass, in particular between the turns of the spring, as will be detailed below.
    Advantageously, the wick holder comprises a channel for conveying air to the reservoir, in order to prevent the reservoir from finding itself in a vacuum as the liquid is drained.
    Preferably, said elastic guide device extends between said proximal and distal ends of the wick, in other words, extends over the entire length of the wick. In addition, said elastic guide device comprises a stop capable of coming into contact with said distal end, which advantageously makes it possible to block the movement of the drill bit in at least one direction of axial movement.
    According to a particular embodiment, and which may constitute an invention as such, the hairdressing apparatus for curling the hair comprises a mandrel, a liquid reservoir, a heating element integrated in the mandrel, a wick communicating with the reservoir so as to be soaked with liquid and means for guiding the wick configured to allow its displacement from a passive position to an active position in which said wick is in contact with the heating element for the creation of steam, said wick comprising a plurality of strands in contact with each other, said strands extending longitudinally. In other words, the wick is made up of several distinct wires or filaments, and the joining, juxtaposition and assembly of these make it possible to form the wick, for example in the manner of a cable. The wick is therefore not made of a continuous material but rather of an assembly of materials. Thus, the physical properties of each of the strands are different from the physical properties of the wick formed by the assembly of these strands. Advantageously, the wick is made up of different strands juxtaposed parallel to each other so as to form a cylinder comprising several strands.
    Still according to this embodiment, each strand is preferably a strand of glass fiber. This embodiment makes it possible to propose a wick made of a material which is particularly resistant to heat, which will give the latter, and therefore the hairdressing apparatus, great durability and great reliability.
    This specific construction notably allows power, depending on the number of strands that are available in the wick, to be able to vary the flow of liquid which is transferred from the reservoir to the heating element. Advantageously, the greater the number of strands the less the flow will be important, since there is very little free space in the wick. Conversely, the fewer the number of strands, the greater the flow. Preferably, the wick comprises 14 strands.
    In a particularly advantageous manner, each strand has a length of between 30 mm and 90 mm and preferably between 50 mm and 70 mm, each of said strands being folded back on itself so as to divide its length by two. Advantageously, the length of each of the strands is about 60 mm, which allows, by folding them back on themselves, to form a wick having a length of 30 mm. Preferably, the bending of the strands forms the distal end of the wick while the free end of the strands forms the proximal end.
    Alternatively, in a manner known as such, and without departing from the scope of the invention, the wick is made of a continuous and uniform material, sufficiently porous to allow the displacement of the liquid by capillarity.
    Preferably, the wick is integral with the reservoir, the guide means being configured to move the reservoir and the wick from the passive position to the active position. Preferably, the reservoir is positioned at the distal end of the mandrel, that is to say at the end furthest from the grip area of the device. Thus, when the user exerts pressure on the reservoir, this has the effect of moving the wick in the active position.
    Advantageously, the hairdressing apparatus comprises a locking / unlocking system configured to maintain the reservoir and the wick in the active position, which avoids the user having to maintain the reservoir and the wick in said active position during the whole looping operation. This advantageous embodiment allows, thanks to the possible axial deformation of said elastic guide device and the drill bit, not to have a hyperstatic system, insofar as neither the elastic guide device nor the drill bit can interfere with the locking / unlocking. Thus, the mechanical stop of the reservoir in the active position is produced only by the locking system and not by the wick since the latter and the elastic guide device can move and / or deform axially elastically.
    Advantageously, the hairdressing appliance further comprises a tile articulated on the appliance to form a clamp with the mandrel so as to move the tile between a position released from the mandrel allowing the positioning of a lock of hair, and a support position against the mandrel, allowing the hair strand to be pinched in order to then carry out the curling operation.
    In addition, the locking / unlocking system comprises a first locking element disposed on the tank and arranged to cooperate with a second locking element disposed at a distal end of the tile. These locking elements maintain the tank in position vis-à-vis the tile when said tile is in the support position against the mandrel and when said tank is moved to the active position. Preferably, according to this embodiment of the hairdressing apparatus, the first locking element and the second locking element are configured to snap into each other. One could however envisage variants of first and second locking elements, without departing from the scope of the invention. Preferably, the first locking element comprises an elastic U-shaped piece provided with a narrowing and the second locking element comprises a stud arranged on an internal face of the tile. The narrowing maintains the elastic part engaged on the stud. Preferably, the locking / unlocking system comprises means for returning the bit to said passive position. This ensures an automatic shutdown of the steam, without requiring additional manipulation of the hair styling device. Preferably, the return means of the locking / unlocking system comprise a spring, the latter being distinct from the spring of the guide means.
    According to a preferred embodiment of the hairstyling device that is the subject of the invention, the locking / unlocking system is configured to ensure that the reservoir and the wick are kept in the active position when the tile is in the support position against the mandrel. This allows you to start the curling and spraying operation, only after you have pinched the lock of hair. Conversely, the locking / unlocking system is configured to allow the reservoir and the wick to be released to its passive position when the tile is in the released position from the mandrel. However, alternative embodiments could be provided according to which the locking / unlocking system fulfills the abovementioned retaining and release functions, independently of the position of the tile with respect to the mandrel.
    According to a preferred variant of the invention, the hairstyling device comprises a unit for counting a duration, a system for detecting the active position of the lock configured to trigger the counting unit as soon as it enters the active position and a signaling system configured to send a signal to a user when the counting unit reaches a defined duration. Thus, the design of the hairdressing apparatus according to the invention makes it possible to initiate a counting of a duration as soon as the wick passes into the active position, which avoids the user having to count the duration of application of the steam and of having to activate an additional button to start said counting, all of these operations being launched automatically when the user manipulates the hairdressing apparatus to move the lock soaked in liquid in the active position. Advantageously, the detection system comprises means for detecting a temperature drop of said vaporization plate, said temperature drop being representative of the start of the vaporization step. Alternatively, the detection system comprises a switch arranged in the mandrel and means for connecting the switch to the counting unit and the hairdressing appliance is configured so that the passage into the active position allows the actuator to be actuated directly. light switch. Alternatively, the hairdressing apparatus comprises a body, the detection system comprising at least one rod extending inside the mandrel and a switch arranged in the body allowing the manipulation of said apparatus, the body being extended by the mandrel and the hairdressing appliance is configured so that the transition to the active position makes it possible to actuate the switch by means of the at least one rod.
    Preferably, the signaling system is configured to emit an audible signal. However, it is possible to envisage variants with a signaling system configured to emit any other type of signal identifiable by the user, such as for example a visual signal.

    detailed description
    As illustrated in FIG. 1, the hairdressing apparatus 1 comprises a body 2, a mandrel 3, a tile 4. The body 2 is configured to allow a user to handle said hairdressing apparatus 1 during its use. The mandrel 3 is cylindrical and extends the body 2 along a longitudinal axis X. The body 2 comprises an inlet 200 for a power cord, for example an electrical cord. In the present description, this arrival 200 advantageously constitutes the point of reference with respect to which the distal and proximal expressions refer: thus the expression "proximal end" refers to an end situated on the side of said arrival 200 while on the contrary the expression “distal end” refers to an end situated opposite said arrival 200.
    The tile 4 is of circular shape adapted (that is to say of complementary shape) to that of the mandrel 3. The proximal end 5 of the tile 4 is fixed to a manipulation finger 6 which is articulated opposite screw of the distal end of the body 2. A pressure on the rear part 8 of the manipulation finger 6 makes it possible to move the tile 4 towards a position released from the mandrel 3, to allow the introduction of a lock of hair between the mandrel 3 and the tile 4. A spring 9, arranged between the distal end 7 of the body 2 and the manipulation finger 6 along an axis substantially perpendicular to the axis X, makes it possible to move the tile 4 in the support position against the mandrel 3, as illustrated in FIG. 1, when one stops pressing on said manipulation finger 6, which allows the pinching of a lock of hair (not shown) positioned between said mandrel 3 and said tile 4 .
    As illustrated in FIGS. 1 to 3 and in FIG. 8, the hairdressing apparatus 1 comprises a reservoir 10 of liquid which has an opening 11 at its proximal end 12. This opening 11 makes it possible to fill in liquid from the reservoir 10. Preferably, the reservoir 10 is filled with water.
    The hairdressing appliance 1 further comprises a heating element 21 integrated in the mandrel 3, that is to say located inside the mandrel 3, as can be seen in FIG. 8. In particular, said element heater 21 comprises on the one hand a vaporization plate 17 and on the other hand a heating means such as for example a positive temperature coefficient thermistor (PTC), which makes it possible to heat said vaporization plate 17 by thermal conduction. Preferably, the vaporization plate 17 comprises a disc oriented perpendicular to the axis X and whose diameter corresponds substantially to the internal diameter of the mandrel 3. The heating element 21 also makes it possible to heat the mandrel 3, in a manner known as such.
    The hairdressing apparatus 1 also includes a wick 13 communicating with the opening 11 of the reservoir 10, which allows it to be soaked with liquid. More specifically, and as can be seen in the various figures, the wick 13 extends between a proximal end 16 intended to come into contact with the heating element 21, and in particular with the vaporization plate 17, and one end distal 20 supplied with liquid from the reservoir
    10, for example by being in contact with it and / or by penetrating inside the latter. In other words, the proximal end 16 is located on the side of the mandrel 3 while the distal end 20 is located on the side of the reservoir 10. Preferably, the wick 13 is a wick of cylindrical shape.
    The hairstyling apparatus 1 also comprises means for guiding the wick 13, and in particular a tubular piece 14 also called a wick 14, fixedly but removably mounted on the reservoir 10 and intended to receive (or support or maintain) the wick 13, as can be seen in FIGS. 2, 3 and 8. More particularly, the wick holder 14 comprises an internal bore 141 extending over the entire length of the wick holder 14 along the axis X and intended to receive especially wick 13.
    The guide means of the wick 13 are configured to allow its displacement from a passive position (position not allowing the production of steam) to an active position (position allowing the production of steam) in which said wick 13 is in contact with the vaporization plate 17 for the creation of steam, and vice versa.
    To this end, the reservoir 10 and the wick holder 14 are mounted in slide connection on the distal end 15 of the mandrel 3, which allows said elements and the wick 13 to be translated along the longitudinal axis X, opposite screw of said mandrel 3, so as to move the assembly (reservoir 10, wick holder 14 and wick 13) from an active position according to which the proximal end 16 of the wick 13 comes to bear against a vaporization plate 17, as illustrated in FIG. 8, position allowing the creation of steam, towards a passive position according to which the proximal end 16 of the wick 13 is released from said vaporization plate 17. Preferably, when the wick 13 is in the passive position, the proximal end 16 is distant from the heating element 21, in particular from the vaporization plate 17, by a distance of between 3 mm and 10 mm, which makes it possible to guarantee the total stopping of the production of steam. Preferably, the stroke separating the passive position and the active position is between 5 mm and 15 mm, and is advantageously substantially equal to 10 mm.
    The means for guiding the wick 13 further comprises an elastic guiding device, such as a preferably helical spring 18, which is in contact with the periphery of the wick 13, that is to say with the outer surface of the wick 13, at the level of the proximal end 16 of the wick 13. More precisely, as illustrated in FIGS. 3 and 8, the wick 13 is located inside the spring 18 so that the section of the latter is constrained by the section of the spring 18. According to this preferred embodiment, the spring 18 extends between the proximal and distal ends 16, 20 of the wick 13, that is to say that it extends over the entire length of the wick 13, thus achieving perfect guidance and maintenance of the latter. In other words, the elastic guide device, in this case the spring 18, is in contact with the periphery of the wick 13 over its entire length. Preferably, the length at rest of the spring is substantially equal to 30 mm, this length corresponding to the preferred length of the wick 13.
    According to the preferred embodiment described here, the wick 13 is of circular section and the internal diameter of the spring 18, which corresponds substantially to the diameter of the wick 13, is substantially equal to 5 mm. Thus, thanks to the spring 18 which envelops the wick 13, the latter is constrained in a volume whose section is fixed, then preventing it from packing and / or deforming, in the radial direction, that is to say - say in the direction perpendicular to the X axis.
    On the other hand, this volume in which the wick 13 is held is elastically deformable in the axial direction, that is to say in the direction of the axis X. In other words, this arrangement makes it possible to contain (c ' that is, to constrain) the wick 13 in a volume stable in diameter, said diameter being substantially equal to 5 mm, regardless of the position (passive position or active position) and the state (wet or dry ) of the wick 13. Indeed, even if the wick is soaked with liquid, which naturally tends to increase its diameter, and even after numerous contact with the vaporization plate 17 (which tends to pack it) , the diameter of the wick 13 remains constant over its entire length. In addition, the dimensional characteristics of the wick 13 remain constant over time, even after many uses, which does not interfere with the proper functioning of the device, either in terms of steam production by the vaporization plate or at the level of the locking system which will be detailed later.
    Advantageously the wick 13 is mounted clamped inside the spring 18, and is therefore immobilized inside the spring 18. Thus the disassembly of the device according to the sub-assemblies illustrated in FIG. 3 is facilitated and the maintenance of the device, and in particular the cleaning of the wick 13, is facilitated, as will be detailed later.
    As can be seen in Figures 3 and 8, said spring 18 comprises a stop 181 adapted to come into contact with the distal end 20 of the drill bit 13. In particular, said stop 181 consists of a turn of spring 18 which is folded so as to form a radius of the spring 18. Thus, the stop 181 prevents the movement of the wick 13 located inside the spring 18 so as to block a degree of freedom according to an axial translation of said wick 13 , and in particular in a direction 32. Thus the wick 13 is prevented by said abutment 181 from entering the tank when the wick 13 is in contact with the vaporization plate 17.
    As can be seen in Figure 8, the spring 18 and the wick 13 are both intended to be mounted inside the wick holder 14 and in particular inside its internal bore 141 along the axis X, for example according to the principle of a sliding connection or a sliding pivot connection.
    According to the preferred embodiment illustrated by the figures, the length of the wick holder 14, or more precisely the length of its internal bore 141 in which the spring 18 is located, is designed so that the spring is constrained (that is, ie compressed) by a few millimeters, preferably between 2 mm and 5 mm, when the hairdressing appliance 1 is in the active position. Consequently, and as mentioned above, the wick 13 is also constrained. In other words, the wick 13 and the spring 18 are both compressed by a few millimeters in the active position of the hairstyling device 1, which makes it possible to optimize the contact between the proximal end 16 of the wick 13 and the vaporization plate 17 and therefore improve the production of steam. Conversely, when the device evolves into a passive position, the wick and the spring are relaxed (to their rest position). In other words, the spring 18 and the wick 13 are caused to move along a translation of axis X inside the internal bore 141 of the wick holder 14. This compression of the wick 13 allows remarkably to give the hairstyling device 1 a pumping effect during the transition to the active position, making it possible to expel any air present in the wick holder 14, and consequently to improve the efficiency of the hairstyling device 1. Indeed, the air being quickly expelled by this pumping effect, the transfer of liquid takes place more quickly between the reservoir 10 and the vaporization plate 17 which makes it possible to produce steam more quickly and therefore to minimize user expectation and the necessary boot phenomenon with known prior art devices. In addition, the repeated translational movement of the wick 13 and the spring 18 in the wick holder 14 makes it possible to limit the formation of tartar since the latter will be eliminated as the wick 13 and spring 18 move.
    Such an assembly, namely the wick 13 arranged inside the spring 18, itself arranged inside the wick holder 14 ensures excellent guidance and maintenance of the wick 13 and the reservoir 10 during axial movement (when the user exerts pressure on the tank 10 to obtain steam), while allowing the tank 10 to be vented. In fact, to allow the liquid contained in the tank 10 to flow towards the heating element by means of the wick 13, it is essential that the latter is not in depression, in other words, it is essential to ensure a venting of the tank 10 so that the pressure does not drop not inside the latter as it empties of its liquid.
    The arrangement proposed by the invention, and in particular the presence of the spring 18 between the wick 13 and the wick holder 14 allows the air to circulate along the turns of the spring 18 and therefore to circulate between the wick 13 and the wick holder 14 as far as the interior of the reservoir, thus allowing good transfer of the liquid using the wick 13. Preferably, the internal bore 141 of the wick holder 14 comprises a channel 142 for conveying the air towards the reservoir, the latter advantageously being formed by one or more grooves peripheral to said internal bore 141 along the axis X, as can be seen in FIG. 8. Thanks to the spring 18 which contains the wick 13, said grooves cannot be obstructed by wick 13, even when the latter is soaked with liquid, thus guaranteeing good ventilation of the reservoir and consequently good flow of the liquid that it contains through wick 13.
    The assembly formed by reservoir 10, the wick holder 14, the wick 13 and the spring 18 is removable from the distal end 15 of the mandrel, which allows access to the opening 11 on said reservoir 10, to effect filling it with liquid. For this, the proximal end 12 of the reservoir 10 is removably assembled, in particular by a snap-fastening, with the bottom 19 of the wicket holder 14. Thus, it is possible for the user to easily disassemble the hairdressing apparatus 1 according to sub-assemblies visible in FIGS. 2 and 3. More specifically, the user can firstly extract the sub-assembly of FIG. 2 consisting of the reservoir 10, the wick holder 14, the wick 13 and the spring 18. Then in secondly, the user can remove the wick holder 14 and the elements it contains (wick 13 and spring 18) from the reservoir 10 in order to access the opening 11 to easily fill the reservoir 10.
    In addition, the handling and maintenance operations of the wick 13, and in particular its descaling, for example, according to a practice well known as such consisting in immersing the latter in vinegar, are greatly facilitated by the invention, in since the wick 13 is enveloped by a radially rigid body, in this case the spring 18. More specifically, the user can firmly grasp the spring 18 and wick 13 sub-assembly between his fingers without fear of damaging the wick 13 since the latter is protected by the spring 18. In addition, the rigidity of said sub-assembly 3060266 is increased, which greatly facilitates the disassembly operations and above all reassembly of said sub-assembly in the internal bore 141 of the wick holder 14.
    A locking / unlocking system 22 is arranged on the hairdressing apparatus 1 to maintain the reservoir 10, the wick holder 14 and the wick 13 in the above-mentioned active position. As illustrated in FIGS. 1 to 5, this locking / unlocking system 22 is implemented between the contour wall 23 of the reservoir 10 and the distal end 24 of the tile 4. The contour wall 23 comprises a groove 25 opening onto its proximal end 26, as illustrated in FIG. 4. This groove 25 receives an elastic part 27 in the shape of a U, said elastic part 27 comprising a narrowing 28, as illustrated in FIG. 4. This elastic part 27 constitutes a first locking element.
    As illustrated in FIG. 5, a stud 29 extends on the side of the internal face of the tile 4, at its distal end 24. The stud 29 constitutes a second locking element configured to be housed in the room elastic 27.
    As explained above, the spring 18 allows the wick 13 to compress along the axis X but without deforming radially, which makes it possible to remarkably improve the operation of the locking / unlocking system. In fact, given the axial displacement of the spring 18 and of the wick 13, the latter, once they are in contact with the vaporization plate 17, will be able to move and / or compress axially, even if the movement of the reservoir 10 continues slightly along the axis X. Thus, there can be no blocking effect linked to a wick which would possibly be too long compared to the stroke of the reservoir 10. Consequently, the handling of the hairdressing appliance 1, in particular when it is blocked in the active position, is thereby made easier for the user.
    When the tile 4 is in abutment against the mandrel 3, in the pinching position of a lock of hair, and the reservoir 10 is in the passive position, the stud 29 comes to be positioned in the groove 25 outside the elastic part 27 When then the reservoir 10 is moved into the active position, said elastic piece 27 engages on the pad 29 in a direction parallel to the axis X until the narrowing 28 exceeds said pad 29, thus allowing the snap-fastening of the elastic part 27 on the stud 29 or vice versa, which ensures that the reservoir 10 is kept in this active position and, consequently, that the wick 13 soaked in liquid is kept against the vaporization plate 17. The device therefore produces steam and remains automatically, that is to say without user action, in this position.
    As illustrated in FIG. 8, return means 31, such as a spring are arranged between the vaporization plate 17 and the wick holder 14, this spring making it possible to exert a force on the wick holder 14, in the direction an arrow representing the direction 32 corresponding to the passage from the active position to the passive position. These return means of the locking / unlocking system are independent and distinct from the spring 18.
    The latching of the stud 29 in the elastic piece 27 keeps the reservoir 10 in position with respect to the tile 4, despite this force exerted by said spring 31. On the contrary, when the tile 4 is moved into the position released vis-à-vis the mandrel 3 by the user, the stud 29 emerges from the elastic part 27 in a movement substantially perpendicular to the axis X, which allows the spring 31 to push the wick holder 14 and the tank 10 (and wick 13) in the passive position, stopping the production of steam. Thus, when the user raises the tile 4 to extract the lock of hair, this has the immediate effect of automatically passing the lock 13 into the passive position, and consequently of stopping the production of steam.
    Advantageously, the hairdressing apparatus 1 comprises a system for detecting the active position of the reservoir 10, the wick holder 14 and the wick 13, according to which steam is generated. This detection system comprises for example means 33 for detecting a drop in temperature of said vaporization plate 17, these detection means 33 themselves comprising a temperature sensor, preferably a thermistor with negative temperature coefficient (NTC) ). This temperature sensor is positioned in contact with the internal face 34 of the vaporization plate 17 (that is to say the face not in contact with the wick 13), as shown diagrammatically in FIG. 6. When the proximal end 16 of the wick 13 comes into contact with the external face 35 of the vaporization plate 17, said vaporization plate 17 undergoes a sudden drop in temperature, which is detected by the temperature sensor. The temperature sensor transmits the information on the temperature drop to an electronic control unit incorporating a counting unit which has a duration, for example of ten seconds, during which the creation of steam and the heating of the mandrel must be maintained. 3 once the lock of hair has been wrapped around said mandrel 3. This duration can be adjusted by the user according to indexed values of duration of exposure to steam, for example 5, 8 or 10 seconds, this adjustment being accessible from a user interface on the hairdressing device 1. Once the time has elapsed, the counting unit transmits the information to the electronic control unit which triggers an audible signal, for example a beep, or even a light signal, indicating to the user to release the tile 4 vis-à-vis the mandrel 3, in order to release the reservoir 10 and the wick 13 in the passive position and thus stop the creation of steam, before removing the lock of curly hair.
    FIG. 7 shows diagrammatically a second alternative embodiment of a system for detecting the active position of the reservoir 10, the wick holder 14 and the wick 13 in contact with the vaporization plate 17. According to this variant, the detection system comprises a switch 38 arranged at the distal end 15 inside the mandrel 3. This switch 38 is connected by connection means 39 such as a cable to the electronic control unit which integrates the counting unit and which is housed in the body 2 of the hairdressing apparatus 1, said cable passing through the mandrel 3 over its entire length. A part 40 of the reservoir 10 is configured to actuate a push button 41 of the switch 38 when the reservoir 10, the wick holder 14 and the wick 13 are moved to the active position, the switch then activating the counting (not shown) located in the electronic control unit.
    The foregoing description makes it possible to grasp the essence of the invention, without limiting its scope. Thus, other variants remain possible, in particular as regards the implementation and arrangement of the elastic guide device or even in the constitution of the wick itself.
    Other characteristics are possible without departing from the scope of the invention. One could for example provide a cover (not illustrated) allowing the distal end 37 of the reservoir 10 to be opened in order to fill it with liquid without having to disassemble said reservoir 10 with respect to the distal end 15 of the mandrel 3.
