Description

STEAM HAIR STYLING APPLIANCE WITH TANK PROVIDED WITH A REVERSIBLE ASSEMBLY AND FIXING SYSTEM OF SAID TANK

The present invention relates to the general technical field of hairdressing appliances, for example for domestic use, and more specifically to the field of hairdressing appliances equipped with a function of vaporizing liquid in the direction of hair, such as hairdressing appliances with steam.

The invention relates more precisely to a hairdressing device comprising a vaporization device for generating a flow of vaporized liquid, a removable reservoir of liquid for supplying said vaporization device, a main body, and a system for assembling and reversibly fixing the tank to said main body.

We already know of hairdressing devices equipped with a function of spraying liquid towards the hair. Indeed, it is known to spray a liquid towards the hair during a hairstyling operation in order to improve the efficiency of the hairstyling operation and the result of the latter. To ensure such a liquid vaporization function, known hairdressing devices are equipped with a reservoir for storing a certain quantity of liquid to be vaporized. As a general rule, this tank is removable, that is to say it is detachable from the rest of the device, so as to make it easier for the user to fill the tank, but also to ensure the safety of the device. user and the device, particularly with regard to electrical regulatory constraints. The user is thus frequently required, typically at least once before each hairstyling operation, to detach the reservoir from the device, to fill the reservoir with liquid, then to put the reservoir back in place in order to enable the function to operate. liquid vaporization of the device.

These hairdressing devices are generally satisfactory, particularly in terms of the hairdressing result obtained. On the other hand, they nevertheless present certain disadvantages or risks during their handling, and in particular during the assembly or disassembly operations of the removable tank.

Indeed, it is particularly important that the reservoir is assembled and attached to the rest of the device in a correct and robust manner, in order to avoid a risk of liquid leaks during use of the hairdressing device, as well as 'a risk of accidental detachment of the tank. These risks are particularly increased due to the fact that the hairdressing devices in question are generally intended to be handled by hand by the user and to undergo numerous movements linked to carrying out hairdressing operations. These leaks or detachment can cause inconvenience for the user, ranging from simple wetting of their clothes for example, to the risk of electrocution, the hairdressing appliances in question generally being electrical appliances. However, the fact remains that the assembly or disassembly operations of the removable tank must be able to be carried out simply and quickly by the user.

As such, different solutions for assembling and fixing the removable tank were considered. Some proposed solutions aim to make the fixing of the removable tank more reliable and more robust. On the other hand, these solutions generally make the design of the hairdressing appliance, and in particular its reservoir, more complex, which has a negative impact on both the simplicity and speed of carrying out the assembly or disassembly operations of the reservoir. by the user, as on the cost of manufacturing the hairdressing device. Other proposed solutions, on the contrary, seek to make the tank assembly and disassembly operations by the user simpler and faster, often to the detriment of the reliability and robustness of the tank fixing.

It should also be noted that, due to the removable nature of the tank and its frequent handling by the user, the tank is particularly susceptible to falls and shocks, which can lead to damage to certain parts of the tank ensuring the fixing of the tank. the latter, which therefore has detrimental consequences for the reliability and robustness of the tank fixing.

There is therefore a need to further improve existing hairdressing devices, in particular in terms of assembly and fixing, and conversely disassembly, of the removable reservoir.

The objects assigned to the invention therefore aim to provide a response to the above-mentioned needs and problems, and to propose in particular a new hairdressing device whose removable reservoir can be assembled and fixed in a particularly simple, rapid and reliable manner.

Another object of the invention aims to propose a new hairdressing device whose removable reservoir can also be detached and separated in a particularly simple, rapid and reliable manner.

Another object of the invention aims to propose a new hairdressing device with a removable reservoir which is particularly compact while still having a high liquid storage capacity.

Another object of the invention aims to propose a new hairdressing device with a removable reservoir which is of particularly simple and robust construction.

Another object of the invention aims to propose a new hairdressing device with a removable reservoir whose use is particularly intuitive and ergonomic.

Another object of the invention aims to propose a new hairdressing device with a removable reservoir which is particularly easy to manufacture.

Another object of the invention aims to propose a new hairdressing device with a removable reservoir whose repair and maintenance are particularly easy.

The objects assigned to the invention are achieved using a hairdressing apparatus comprising a vaporization device for generating a flow of vaporized liquid, a removable reservoir of liquid for supplying said vaporization device, a main body, and a system for reversibly assembling and fixing the tank to said main body, said apparatus being characterized in that the main body comprises a surface for receiving the tank, said reversible assembly and fixing system comprising:
– at least a first tenon which projects from said receiving surface and a first housing provided in one face of the reservoir to receive said first tenon and guide the reservoir in translation relative to the main body in a direction of translation between a first position and a second position and vice versa, said first tenon and first housing having respective complementary hooking portions which cooperate when the tank is in said second position to prevent any movement of the tank in a direction secant to said direction of translation, and
– an automatic locking device, comprising at least a first locking member carried by the main body and at least a second locking member carried by the tank which cooperate together when the tank is in said second position to oppose a translation from the tank towards said first position.

The invention relates to a hairdressing device 1, that is to say a device designed and configured to allow a user to carry out one or more hairdressing operations, for example to ensure hair shaping, and/or hair beautification and/or improvement of hair health, that is to say a treatment operation on the hair (or possibly hair, in the case of use on an animal for example). Preferably, the hairdressing device 1 is designed so that the user uses the hairdressing device 1 on himself, that is to say on his own hair. However, it is perfectly conceivable that the hairdressing appliance 1 is designed for use by the user on the hair of a third person (or other user). The hairdressing appliance 1 is preferably designed for use in a domestic setting, more preferably by a user lacking particular professional skills in hairdressing. The hairdressing appliance 1 is preferably portable, that is to say that at least part, and preferably all, of the appliance 1 is designed to be grasped and manipulated by hand. The hairdressing device 1 is preferably a portable electrical device intended to be connected to the electricity distribution network to be electrically powered. However, it is alternatively possible, without departing from the scope of the invention, for the hairdressing appliance 1 to carry electrical power batteries, possibly rechargeable. In the embodiment illustrated in the figures, the hairdressing appliance 1 constitutes a hairdressing brush, and more specifically a steam hairdressing brush. The invention is however not limited to a hairdressing device 1 forming a hairdressing brush, and the hairdressing device 1 can for example constitute a straightening brush, a detangling brush, a straightener or even a curler, without however that we go beyond the scope of the invention.

As illustrated in the figures, the hairdressing appliance 1 comprises a main body 2, a portion of which advantageously forms at least in part a handle 3 for manual gripping, which is intended to be grasped by hand, and advantageously gripped, by the user, to manipulate the hairdressing appliance 1. The handle 3 extends for example longitudinally, along a central longitudinal axis A-A', between a first end from which emerges for example an electrical power cable, and a second opposite end. The hairdressing appliance 1 advantageously comprises a head 4 for engaging the hair, for interacting with the hair, that is to say for preferably coming into contact with the hair in order to subject it to mechanical, thermal and/or fluidics. The head 4 is advantageously formed at least partially by a portion of the main body 2, and extends for example in a direction of average longitudinal extension, between a rear end secured to the second end of the handle 3, and a free front end . Preferably, as illustrated in the figures, the handle 3 has a substantially elongated shape which is extended by the head 4, which is advantageously wider than the handle 3 and has for example a generally substantially oblong shape.

Preferably, the head 4 extends between said rear end and said free front end along a central longitudinal axis which is substantially coincident with the central longitudinal axis A-A' of the handle 3. Thus, as in the embodiment illustrated in the figures , the main body 2 therefore extends an average longitudinal extension direction B-B', which is coincident with the (or at least parallel to) central longitudinal axis of the handle 3 and average longitudinal extension direction of the head 4. Alternatively, however, it could be envisaged that the central longitudinal axis A-A' of the handle 3 and the direction of average longitudinal extension of the head 4 are intersecting, so that the main body 2 would then have a bent shape. Preferably and as illustrated, the main body 2 forms a housing, for example made of plastic. The head 4 advantageously has a front face 4A which, as in the embodiment illustrated in the figures, is preferably provided with brushing pins 5 between and against which the hair is intended to be and to move, during use. of the hairdressing appliance 1.

It will be noted here that it is possible that, according to a variant not illustrated and depending on the type of hairdressing device 1 targeted, the device 1 comprises, in addition to said main body 2, a secondary body which could be mechanically connected to said main body 1. For example, the main body 1 and the secondary body could respectively form a first arm and a second arm, which could be connected together by a hinge so as to form a movable clamp between an open position and a closed position .

The hairdressing apparatus 1 according to the invention comprises a vaporization device for generating a flow of vaporized liquid, which flow of vaporized liquid is advantageously intended to be directed towards and on the hair to be treated as part of the production of a hair styling operation. Preferably, the vaporization device is carried by the main body 2 of the hairdressing appliance 1.

Preferably, the liquid concerned is water, for example distilled water or running tap water. However, the invention is not limited to such a particular liquid, and the liquid in question can therefore be any other liquid capable of being projected onto the hair as part of a hairdressing operation to contribute to a particular treatment. hair. For example, said liquid can be an aqueous, oily, or even alcoholic-based cosmetic product.

The term “vaporization” must be considered here in its broadest sense. Thus, according to a variant, the vaporization device can be designed and configured to disperse and project the liquid, typically at room temperature, in the form of a flow of fine droplets of liquid, for example in the manner of a mister, and this therefore without change in state of the liquid. According to another variant, implemented in the embodiment illustrated in the figures, the vaporization device is preferably designed to bring the liquid to a temperature higher than its vaporization temperature (boiling temperature) and thus generate a flow of vapor from said liquid, by a change of state of said liquid. In this preferential case, the term " vapor " must then also be taken in an extensive sense and can thus designate a substance (preferably water) in the gaseous state, or said substance (preferably water). water) in the liquid state in the form of a mist of droplets and/or microdroplets, or even a mixture of said substance (preferably water) in the gaseous state and of said substance (preferably water) in the liquid state in the form of a mist of droplets and/or microdroplets.

Thus, as in the embodiment illustrated in the figures, the vaporization device can advantageously comprise a vaporization chamber 6 provided with a liquid supply inlet, and at least one vapor outlet 7. Preferably and as illustrated, the vaporization device also comprises a heating device 8 (for example one or more heating elements, or thermistor(s), with a “Positive Temperature Coefficient” (PTC)) for heating the vaporization chamber 6 and bring the latter to a temperature higher than a vaporization temperature (boiling temperature) of the liquid, so as to transform, within the vaporization chamber 6, the liquid into vapor. The steam outlet 7 is advantageously in fluidic communication, preferably permanent, with the surrounding outside air, preferably via at least one steam ejection orifice 9, advantageously disposed on the side of the front face 4A of the head 4 of the hairdressing appliance 1. Preferably, said steam ejection orifice 9 is carried by at least one of the brushing pins 5, which then advantageously forms at least one steam pin 5A.

Advantageously, the hairdressing appliance 1 further comprises at least one heating element intended to come into contact with the hair, to transmit heat to it. As in the embodiment illustrated in the figures, the hairdressing appliance 1 can then be preferably designed so that the user's hair can be simultaneously in contact at least locally with the heating element, and subjected at least locally to a flow of vaporized liquid, during the styling operation, during which the head 4 engages the hair, for example to brush it, preferably by means of the aforementioned brushing pins 5. Advantageously, the heating element is carried by the head 4 of the hairdressing appliance 1, and preferably by the front face 4A of said head 4. For example, the heating element can include at least one of the pins of brushing 5, which then forms at least one heating pin 5B.

The hairdressing appliance 1 comprises a liquid reservoir 10, for storing a certain quantity of the liquid intended to be vaporized, and supplying the vaporization device with liquid. According to the invention, the tank 10 is removable, that is to say it is designed and configured to be assembled and attached to, and conversely to be detached and separated from, the rest of the device 1 (and in particular of the main body 2 of the latter) at will by the user, and this without damage to either the reservoir 10 or the main body 2, and advantageously without requiring particular tools or complex manipulations. In particular, the tank 10 can thus be in a so-called “attached” configuration, in which the tank 10 is assembled and fixed to the main body 2, so that it is therefore integral with the latter. In this attached configuration, illustrated as an example in Figures 1, 2, 9 and 10 in particular, the reservoir 10 is advantageously arranged in sealed fluid communication with the vaporization device, so that the liquid contained in the reservoir 10 can thus be delivered to the device vaporization with a view to being vaporized by the latter and diffused outside the hairdressing appliance 1, preferably towards and on the user's hair. Alternatively, the tank 10 can be in a so-called “detached” configuration, in which the tank 10 is disassembled and is no longer attached to the main body 2, so that it is therefore not attached to the latter, as illustrated. for example at the . Preferably, the reservoir 10 is then completely separated and independent from the main body 2 (no residual mechanical link therefore remaining between the reservoir 10 and the main body 2), so that the reservoir 10 can then be freely and easily manipulated by the user, for example to fill the tank 10, to clean it or even to replace it.

For example, the tank 10 may comprise two half-shells 11A, 11B, which are assembled to one another, in a sealed manner and advantageously not removable (for example by gluing or welding), so as to define between them a internal cavity 12 intended to receive and contain liquid. Preferably, the capacity of the reservoir 10 is between 0.005 liter and 0.5 liter, and more advantageously between 0.015 liter and 0.1 liter. Preferably, the reservoir 10 is (essentially) made of plastic. For example, each of said half-shells 11A, 11B is made of plastic material, preferably rigid. Advantageously, as illustrated in the figures, the reservoir 10 extends longitudinally along an axis C-C' of average extension, between a first end 13A and an opposite second end 13B. The reservoir 10 thus advantageously has a generally elongated shape, which is particularly adapted, in terms of size in particular, to a respective advantageously elongated shape of the main body 2, and also makes it possible to maximize the capacity of the reservoir 10.

Preferably, the reservoir 10 comprises a fluid connection device 14, visible in example at the in particular, intended to cooperate in a removable manner with a complementary fluidic connection device 15, visible in example at the in particular, with which the main body 2 of the hairdressing appliance 1 is respectively provided to ensure fluid communication, advantageously sealed, of the reservoir 10 with the vaporization device and allow the supply of the latter with liquid, when the reservoir 10 is in attached configuration. Advantageously, as in the embodiment illustrated in the figures, the fluid connection device 14 carried by the reservoir 15 is a male connection device, comprising for example a portion of tube which extends projecting from an external surface of the reservoir 10. Conversely, the complementary fluidic connection device 15 carried by the main body 2 is a female fluidic connection device, typically comprising an orifice intended to receive the tube portion. Alternatively, the fluidic connection device 14 could be a female connection device, and the complementary fluidic connection device 15 could be a male fluidic connection device. When the reservoir 10 is in attached configuration, the fluidic connection device 14 and the complementary fluidic connection device 15 cooperate, in an advantageously sealed manner, in order to allow the liquid contained in the reservoir 10 to supply the vaporization device. Advantageously, the female fluid connection device comprises a part of elastically deformable material, through which said orifice is formed, the internal diameter of which is (slightly) less than an external diameter of said tube portion. Thus, the cooperation of the tube portion with said orifice advantageously results in an elastic deformation of the wall of the orifice, so as to ensure the tightness of the fluid connection. Preferably, the male fluid connection device 14 is arranged at one of the (longitudinal) ends 13A of the reservoir 10, as can be seen in the , and extends longitudinally parallel to the axis CC' of average extension of the tank 10.

Advantageously, the reservoir 10 comprises a filling orifice 16 through which the user can fill the reservoir 10, for example using a funnel or a filling pipette, and a cap 17 intended to close sealing the filling port 16, once the reservoir 10 filled with liquid. Optionally, the tank 10 may comprise a venting orifice of the tank 10, having a diameter typically less than the diameter of the filling orifice, to ensure ventilation of the tank 10 during its filling and to facilitate thus the filling operation. The reservoir 10 can then include a cap intended to seal said vent port, once the reservoir 10 is filled with liquid. Preferably, the tank 10 further comprises a venting device 18 designed and configured on the one hand to prevent the liquid from flowing out of the tank 10, and on the other hand to maintain the tank 10 at a atmospheric pressure by automatically compensating with ambient air a volume of liquid taken from the tank 10 during use of the device 1. This avoids the creation of a depression within the tank 10, likely to hinder distribution of liquid by the tank 10 in operation of the device 1. For example, the venting device 10 comprises a valve provided with a head in the shape of an umbrella or mushroom, arranged inside the tank 10 , and a foot which extends said head. This shape allows, thanks to the weight of the liquid pressing on the cap or the head of the valve, to keep the valve pressed against an internal surface of the reservoir 10 and therefore to prevent the liquid from flowing out of the reservoir 10. On the other hand when the pressure decreases inside the tank 10, the external atmospheric pressure exerts a thrust on the foot of the valve against the weight of the liquid, which allows air to enter inside the tank 10 Once the pressure inside the tank 10 is balanced with the external (atmospheric) pressure, the valve returns to its initial position thanks to the weight of the liquid in accordance with the above.

As visible by example in Figures 8, 10 and 14, the tank 10 advantageously comprises a suction pipe 19, which is arranged inside the tank 10, and which is connected to the fluid connection device 14 in a sealed manner. Advantageously flexible, the suction pipe 19 preferably extends inside the tank 10 between one end connected to the connection device 15 and an opposite free suction end, which is preferably provided with a ballast 20. This allows the suction pipe 19 to be driven by gravity where the liquid is itself driven by gravity during the movements of the hairdressing appliance 1. This promotes good suction of the liquid inside the reservoir 10 and this regardless of the filling level and the position in space of the latter.

Preferably, as in the embodiment illustrated in the figures, the hairdressing appliance 1 comprises, included more generally in a liquid supply device of the vaporization device, a pump 21 and an electric motor 22 for actuating this last, to take liquid from the reservoir 10 and deliver it to the vaporization device, in order therefore to supply the latter with liquid. Preferably, the pump 21 is a peristaltic pump. The pump 21 and the electric motor 22 are preferably arranged in the main body 2, and for example in the portion of the main body 2 forming the handle 3. Advantageously, the pump 21 is connected on the one hand to the complementary connection device 15 mentioned above, and on the other hand to the vaporization device, and in particular to the liquid supply inlet of the vaporization chamber 6 of the latter.

The main body 2 of the hairdressing appliance 1 comprises a receiving surface 23 of the reservoir 10, that is to say a portion of surface intended to receive said reservoir 10. The receiving surface 23 defined by the main body 2 is advantageously oriented towards the outside of the main body 2. Preferably, as in the embodiment illustrated in the figures, the receiving surface 23 is defined by the portion of the main body 2 forming (at least partially) the handle 3, rather than by the portion of the main body 2 forming the head 4 of the device 1. When it is in attached configuration, the reservoir 10 is therefore preferentially carried by the portion of the main body 2 forming (at least partially) the handle 3. This makes it possible in particular to reduce the bulk and mass of the head 4 of the device 1. Advantageously, the reservoir 10 is then designed and configured so as to form a part of the handle 3, when the reservoir 10 is in configuration attached, the other part of the handle 3 therefore being formed by the main body 2. As illustrated by example in Figures 1, 2 and 9, the reservoir 10 is therefore advantageously shaped and dimensioned so that, in attached configuration, the reservoir 10 defines with the corresponding main body portion 2 a part of the device 1 which can be grasped with the user's full hand. This makes it possible in particular to reduce the general size of the device 1. This also makes it possible to reduce the risk of using the device 1 without a tank 10, potentially likely to cause degradation of the latter, for example by inattention of the user. Indeed, the absence of reservoir 10 assembled and fixed to the main body 2 then tends to hinder the good manual gripping of the device 1, or at the very least to make the gripping of the device 1 less pleasant, less natural. by the user, so that the latter's attention is drawn to the absence of the reservoir 10.

The hairdressing appliance 1 according to the invention comprises a reversible assembly and fixing system of the reservoir 10 to the main body 2 to therefore allow the reservoir 10 to be assembled and fixed to, and conversely to be detached and separated from, main body 2 of the device 1 by the user, and therefore to evolve from one to the other of said “attached” and “detached” configurations and vice versa. According to the invention, the reversible assembly and fixing system comprises at least on the one hand a first tenon 24 which projects from the main body 2, and more specifically from said receiving surface 23 defined by the latter, and on the other hand a first housing 25 which is provided in a face 26 of the reservoir 10 to receive said first tenon 24 and guide the reservoir 10 in translation relative to the main body 2 (and in particular relative to the receiving surface 23) according to a direction Δ of translation between a first position and a second position and vice versa. In other words, the main body 2 therefore carries a first guide element formed by the first tenon 24, which is carried by the main body 2, and which is designed and configured to be received, that is to say to be housed, in a first complementary guide element which respectively carries the reservoir 10 and which is formed by said first housing 25. The first tenon 24 and the first housing 25 are shaped and configured so that, when the first tenon 24 is received in the first housing 25, the cooperation of the latter with each other thus makes it possible to guide a movement of the reservoir 10 relative to the main body 2 in translation in said direction Δ of translation, and in this respect 'one towards the other of said first and second positions, and vice versa.

Said first tenon 24 and first housing 25 have respective complementary attachment portions 27, 28 which cooperate, typically by complementarity of shape, when the reservoir 10 is in said second position to prevent any movement of the reservoir 10 in a secant direction at said direction Δ of translation, and in particular in a direction normal to the receiving surface 23 defined by the main body 2. In other words, the main body 2 therefore carries a first attachment element formed by the portion of hooking 27 of the first tenon 24, which is designed and configured to cooperate with a first complementary hooking element carried by the tank 10 and which is formed by the respective hooking portion 28 of the first housing 25, so as to mechanically prohibit any possibility of moving the tank 10 in a direction secant to the direction Δ of translation, when the tank 10 is in said second position. Thus, once in the second position, the reservoir 10 can only be moved relative to the main body 2 by translation in the direction Δ of translation. Said face 26 of the reservoir 10 is therefore a fixing face of the reservoir 10, via which the reservoir 10 is therefore intended to be connected in translation in the direction Δ of translation between said first and second positions, and to be attached to the main body 2. Thus, as illustrated in the figures, the fixing face 26 is therefore arranged facing the receiving surface 23 when the reservoir 10 is in the second position. Advantageously, in the second position, the face 26 for fixing the reservoir 10 covers substantially the entirety of the receiving surface 23.

Advantageously, as in the embodiment illustrated in the figures, said first and second positions are positions in which the reservoir 10 is arranged in contact, at least locally, with the receiving surface 23 defined by the main body 2, by the intermediate of said face 26 of the tank 10 in which the first housing 25 is provided. Thus, the movement of the tank 10, by the user, in translation in the direction Δ of translation advantageously corresponds to a sliding of the tank 10 against the main body 2, and in particular on and against the receiving surface 23.

The reversible assembly and fixing system further comprises an automatic locking device, to automatically lock the reservoir 10 in said second position. More specifically, the automatic locking device comprises at least a first locking member 29 carried by the main body 2 and at least a second locking member 30 respectively carried by the reservoir 10, which cooperate together ( ie which are designed and configured to cooperate together) when the reservoir 10 is in said second position to oppose a translation of the reservoir 10, in said direction Δ of translation, in particular towards said first position. Thus, after the user has assembled the tank 10 to the main body 2 so as to position the tank 10 in the first position (Figures 7 and 8), then manually moved the tank 10 in translation following the direction Δ of translation of the first position to the second position (Figures 9 and 10), the first and second locking members 29, 30 cooperate with each other automatically, that is to say without particular manual action of the user against them, so as to immobilize the reservoir 10 relative to the main body 2 in the second position. Thus arranged and locked in position in the second position, the reservoir 10 is thus advantageously in attached configuration.

Thanks to the above-mentioned characteristics, it therefore becomes advantageously possible to obtain a hairdressing appliance whose removable reservoir 10 can be assembled and fixed in a particularly simple, rapid and reliable manner by the user. It also advantageously becomes possible to ensure, as in the embodiment illustrated in the figures, that the tank 10 is devoid of any element specifically designed to ensure attachment to the main body 2 which would project from the surface of the tank 10, and which would therefore be likely to be easily damaged in the event of a fall or impact of the tank 10 during its handling by the user. This thus results in greater robustness both of the reservoir 10 and of the reversible assembly and fixing system of the latter to the main body 2 of the hairdressing appliance 1. This ultimately contributes to conferring more generally to the hairdressing appliance 1 greater robustness.

In the case where, as in the embodiment illustrated in the figures, the receiving surface 23 is defined by a portion of the main body 2 forming (at least partially) the handle 3 of the hairdressing appliance 1, and that the latter extends longitudinally along a central longitudinal axis A-A' as envisaged previously, the direction Δ of translation of the reservoir 10 is advantageously defined parallel to said central longitudinal axis A-A', that is to say that the central longitudinal axis A-A 'extends in the direction Δ of translation. In the case, not illustrated, where the receiving surface 23 is defined by a portion of the main body 2 forming (at least partially) the head 4 of the hairdressing appliance 1, and that the latter extends in a direction d average longitudinal extension as envisaged previously, the direction Δ of translation of the tank 10 is advantageously defined parallel to the direction of average longitudinal extension. More generally, in the case where the main body 2 extends in an average longitudinal direction of extension B-B', said direction Δ of translation of the tank 10 is advantageously defined parallel to said direction of longitudinal extension B-B' . Such an orientation of the direction Δ of translation contributes in particular to the intuitive and ergonomic nature of the assembly and fixing, and reciprocally the disassembly and separation, of the tank 10.

Preferably, the reservoir 10 extends longitudinally along an axis C-C' of average extension of the reservoir 10, as mentioned previously, and the direction Δ of translation of the reservoir 10 is advantageously defined parallel to the axis C-C' of average extension of the reservoir 10. In other words, as in the embodiment illustrated in the figures, the reservoir 10 is intended to be received by the receiving surface 23 with its axis C-C' of average extension oriented in the direction Δ of translation .

Typically, the receiving surface 23 extends, in the direction Δ of translation, between two lateral edges 23A, 23B. Advantageously, as in the embodiment illustrated in the figures, the side edges 23A, 23B are free side edges. The main body 2 is therefore in particular devoid of wall(s) which would laterally delimit the receiving surface 23, and facing and against which the tank 10 would slide when it moves in translation between the first and second positions . The design of the hairdressing appliance 1 is thus advantageously simplified and lightened. The implementation of free side edges 23A, 23B advantageously also contributes to making the assembly and disassembly operations of the tank 10 by the user even easier, by facilitating access to the receiving surface 23 and to the tank. 10. This also makes it possible to maximize the dimensions of the tank 10 and therefore the capacity of the latter with regard to the respective dimensions of the main body 2. This advantageously also allows a more compact, more ergonomic and more harmonious integration of the tank 10 to the body main body 2. For example, as illustrated in the figures, the reservoir 10 can thus be shaped so as to present a transverse section in an arc of a circle, which completes a transverse section in an arc of a circle which respectively presents the part of the main body 2 which receives the reservoir 10, so as to locally give the device 1 equipped with the reservoir 10 an advantageously circular or ovoid transverse section. Advantageously, the receiving surface 23 has a (first) free end edge 23C which interconnects the two lateral edges 23A, 23B, which are therefore preferentially free, which advantageously provides the same advantages as those mentioned above. acting on the free character of the side edges 23A, 23B. Furthermore, the free character of the (first) free end edge 23C advantageously makes it possible to match the dimensions of the receiving surface 23 with the respective dimensions of the tank fixing face 26 10, so that the receiving surface 23 is completely covered by the face 26 for fixing the tank 10 when the latter is in the second position. The aforementioned characteristics thus advantageously contribute to enabling a particularly compact, ergonomic and aesthetic design of the device 1.

Advantageously, the first tenon 24 and the first corresponding housing 25 are designed and configured so that, in said first position, the hooking portion 27 of the first tenon 24 does not cooperate with the respective hooking portion 28 of the first housing 25 to prevent any movement of the tank 10 in a direction secant to said direction Δ of translation. Thus, the first position advantageously constitutes a position (or “docking position”) in which the tank 10 is attached to the main body 2, advantageously in contact against the latter, and in which it nevertheless remains advantageously possible for the user to move the reservoir 10 relative to the main body 2 in a direction secant to the direction Δ of translation, and advantageously in particular in a direction normal to the receiving surface 23 defined by the main body 2. This advantageously contributes to further facilitating the assembly of the tank 10 to the main body 1, as well as reciprocally the disassembly of the tank 10 from the main body 2.

As such, the first housing 25 advantageously comprises a guide portion 31, advantageously delimited by two side walls 31A, 31B, and which is designed and configured to receive the first tenon 24 when the reservoir 10 is in said first position (Figures 7 and 8), and to guide the first tenon 24 towards the hooking portion 28 of the first housing 25 when the reservoir 10 moves in translation, in the direction Δ of translation, towards said second position. When the first tenon 24 is received in the guide portion 31 of the first housing 25, the reservoir 10 thus retains a degree of freedom in translation relative to the main body 2 in a direction secant to the direction Δ of translation, and advantageously in a direction normal to the receiving surface 23. On the other hand, when the reservoir 10 reaches the second position, the hooking portion 27 of the first tenon 24 is then received by the respective hooking portion 28 complementary to the first housing 25, and the cooperation of the attachment portions 27, 28 then opposes any movement of the reservoir 10 in a direction secant to the direction Δ of translation (Figures 9, 10 and 11 in particular).

Advantageously, as can be seen in the example in the , the side walls 31A, 31B of the guide portion 31 are not arranged parallel to each other, but approach each other in the direction of the hooking portion 28 of the first housing 25. The first housing 25 therefore has a flared shape, the first housing 25 having a (transverse) passage section narrowing towards the hooking portion 28 of the first housing 25. This contributes in particular to further facilitating the assembly and fixing of tank 2 to the main body 1 by offering a certain angular tolerance to the relative arrangement of the tank 10 and the main body 2 when the tank 10 is in the first position, while ensuring increasingly precise guidance at as the tank 10 moves towards the second position.

As can also be seen in the example of , said first housing 25 advantageously has a bottom 32, and the guide portion 31 has an end wall 31C which interconnects the side walls 31A, 31B of the guide portion 31 and which forms a ramp inclined towards the bottom 32 and the attachment portion 28 of the first housing 25. The assembly and fixing of the tank 10 to the main body 1 are thus facilitated, said inclined ramp thus being able to advantageously come into contact with the first tenon 24 during the assembly of the tank 10 to the main body 2, so as to guide the reception of the first tenon 24 in the guide portion 31 of the first housing 25. The presence of such an inclined ramp also advantageously makes it easier to disassemble the tank 10, insofar as a movement of the tank 2 in the direction Δ of translation, in the direction of the first position towards the second position, advantageously results in a lifting, a spacing, of the tank 10 relative to the main body 2, by placing in contact with the first tenon 24 and the inclined ramp as illustrated in , which thus facilitates handling of the reservoir 10 by the user with a view to its removal.

Preferably, the second position of the reservoir 10 is a stop position, beyond which the reservoir 10 cannot move in translation in the direction Δ of translation. As such, as in the embodiment, the main body 2 advantageously has an abutment face 33, against which the reservoir 10 comes into contact, advantageously through its first longitudinal end 13A, when it reaches the second position. As in the embodiment illustrated in the figures, the abutment face 33 is advantageously arranged along another end edge 23D (second end edge) of the receiving surface 23, which connects the side edges 23A, 23B of this last, and which is arranged opposite the (first) end edge 23C advantageously free from the receiving surface 23 such as the latter was introduced previously. Advantageously, the stop face 33 carries the complementary connection device 15 mentioned above. Alternatively, or preferably in a complementary manner, the hooking portion 28 of the first housing 25 comprises a stop 28A against which the hooking portion 27 of the first tenon 24 comes into contact when the reservoir 10 reaches the second position (as visible as an example at ) to prevent translation of the tank 10 beyond the second position.

In particular in order to optimize the robustness and reliability of the attachment of the tank 10 to the main body 2 when the tank 10 occupies the second position, the first tenon 24 preferably has a part of "T" section (as illustrated in particular in the ) or of isosceles trapezoidal section, at least part of which forms said hooking portion 27 of the first tenon 24. In return, the hooking portion 28 of the first housing 25 carried by the tank 10 therefore has a section whose shape is advantageously complementary to the “T” section part (as illustrated in particular in ) or isosceles trapezoidal section of the first tenon 24. In the case of an isosceles trapezoidal section of the first tenon 24, the cooperation of the hooking portion 27 of the first tenon 24 with the hooking portion 28 of the first housing 25 corresponds therefore advantageously to a “dovetail” assembly of the tank 10 to the main body 2.

Preferably, the reversible assembly and fixing system comprises a second tenon 34 which projects from said receiving surface 23, the first and second tenons 24, 34 then being distinct and spaced apart from each other and being aligned following said direction Δ of translation. In other words, the first and second tenons 24, 34 are aligned along an axis which is parallel to, or coincides with, the direction Δ of translation. The reversible assembly and fixing system further preferably comprises a second housing 35, which is provided in said face 26 of the reservoir 10 (that is to say in the same face 26 as that on which the first housing is provided 25) to receive the second tenon 34 and guide the translation of the reservoir 10 in said direction Δ of translation. Advantageously, the second housing 35 is distinct and distant from the first housing 25. As illustrated by example in the figure, the first and second housings 25, 35 are therefore respectively aligned along an axis which is parallel to, or coincides with, said direction Δ translation when the tank 10 is arranged in the first position and when the tank 10 is arranged in the second position. The implementation of such additional corresponding second tenon 34 and second housing 35 advantageously contributes to facilitating and making the assembly, and conversely the disassembly, of the reservoir 10 in relation to the main body 2 of the hairdressing appliance 1 even more reliable.

According to a preferred variant, implemented in the embodiment illustrated in the figures, the second tenon 34 is devoid of a hooking portion to prevent any movement of the reservoir 10 in a direction intersecting said direction Δ of translation when the reservoir 10 is in the second position. According to this variant, the second tenon 34 and the second corresponding housing 35 therefore only ensure, by cooperation with one another, guiding the movement of the reservoir 10 in translation in the direction Δ of translation. As illustrated in the figures, the second tenon 34 is then advantageously devoid of a hooking portion to prevent movement of the reservoir 10 in a direction secant to the direction Δ of translation when the reservoir 10 is in the first position. This makes it possible in particular to simplify the design of the reversible assembly and fixing system and to further facilitate the assembly of the tank 10. In this case, the second housing 35 can then advantageously take the form of a groove formed in said face 26 of the tank 10 and opening, over its entire length, from said face 26 ( ).

Still in order to further facilitate the assembly by the user of the reservoir 10 to the main body 2, the second tenon 34 is preferably arranged downstream of the first tenon 24 in the direction Δ of translation and in the direction of translation from the first position towards the second position of the reservoir 10. For example, the second tenon 34 extends from at least the second end edge 23D of the receiving surface 23 towards the first tenon 24 and the first end edge 34C (advantageously free ) of the receiving surface 23. In this case, the second housing 35 opens preferentially from a corresponding end face 36 of the tank 10, so that when the tank 10 moves in translation from the first position to the second position, the second tenon 34 engages in the second housing 35 via said end face 36. In order to facilitate such engagement of the second tenon 34 by said end face 36 and to make the guidance at translation of the reservoir 10, the second tenon 34 advantageously has, in the direction of the direction Δ of translation and opposite the first tenon 24, a tapered leading end 34A, that is to say of a convergent shape, for example in a point formed by two inclined sides which meet along a sharp or rounded edge.

According to an alternative variant not illustrated, the second tenon 34 is provided on the contrary with a hooking portion to prevent any movement of the reservoir 10 in a direction intersecting the direction Δ of translation when the reservoir 10 is in the second position. The second housing 35, carried by the reservoir 10, advantageously has a complementary attachment portion, designed and configured to cooperate with said attachment portion of the second tenon 34 when the reservoir 10 is in the second position to prevent any movement of the tank 10 in a direction secant to the direction Δ of translation. Advantageously, the second tenon 34 and the corresponding second housing 25 are designed and configured so that, in said first position, the hooking portion of the second tenon 34 does not cooperate with the respective hooking portion of the second housing 35 to prohibit any movement of the reservoir 10 in a direction secant to said direction Δ of translation.

Advantageously, as visible in Figures 3 and 4 in particular, the second tenon 34 rises from the receiving surface 23 to an upper end portion 34B, which has, in the direction Δ of translation, a transverse section of convergent shape ( towards the outside of the main body 2), for example defined by at least two inclined sections which meet along a sharp or rounded edge aligned in the direction Δ of translation, as visible for example in Figures 3 and 4 in particular. Such a particular conformation of the upper end portion 34B of the second tenon 34 advantageously contributes in particular to facilitating the installation of the reservoir 10 in its first position by the user.

Advantageously, as in the embodiment illustrated in the figures, the surface of the reservoir 10 is devoid of any element or portion which projects from said surface in a direction secant to the direction Δ of translation, and which is specifically designed to ensure guiding and/or hooking of the tank 10 to the main body 2. In particular, the face 26 (fixing face) of the tank 10 in which the first housing 25 (and the second housing) is provided 35 where appropriate), is advantageously devoid of any element or portion for guiding and/or attaching the reservoir 10 to the main body 2 which projects from said face 26. Advantageously, the surface of the fixing face 26 of the tank 10 is substantially flat, as illustrated by example in Figures 5 and 6 in particular. Alternatively or preferably in a complementary manner, the main body 2 is for its part preferably devoid of any element or portion for guiding and/or attaching the reservoir 10 to the main body 2, apart from the first tenon 24 and the second tenon 34 if necessary, which projects (does) project from the receiving surface 24 defined by the main body 2. Advantageously, the receiving surface 23 is substantially flat, as illustrated by example in Figures 3, 4 and 6 in particular .

Advantageously, when the second tenon 34 does not have a hooking portion, the reversible assembly and fixing system can comprise first and second additional blocking means, which cooperate together when the reservoir 10 is in the second position to prevent any movement of the reservoir 10 in a direction secant to the direction Δ of translation, and in particular in a direction normal to the receiving surface 23. For example, as in the embodiment illustrated in the figures, said additional blocking means can be formed by the fluidic connection device 14 and the complementary fluidic connection device 15.

Preferably, as illustrated by example in the figures, the axis along which the first and second tenons 24, 34 are aligned, and which is parallel to, or coincides with, the direction Δ of translation of the reservoir 10, is centered relative to the receiving surface 23. In other words, said axis splits the receiving surface 23 into two portions of the same surface area which are arranged on either side of said axis. This helps to guarantee excellent stability of the translation guidance of the tank 10 attachment.

Advantageously, as in the embodiment illustrated in the figures, the automatic locking device is an automatic locking and unlocking device. This contributes to simplifying the design of the device and in particular of the reversible assembly and fixing system of the tank 10, but also to making the operation of disassembling the tank 10 by the user even easier and more ergonomic. Indeed, the reversible assembly and fixing system is then advantageously devoid of a manual control member, distinct from the reservoir 10, on which the user would have to act manually to control unlocking of the automatic locking device.

Preferably, one of said first and second locking members 29, 30 forms a male locking member, while the other of said first and second locking members 29, 30 forms a female locking member designed and configured to receive said male locking member when the reservoir 10 is in said second position, to oppose a translation of the reservoir 10 towards the first position in the direction Δ of translation, by cooperation between the male and female locking members. For example, the male locking member is formed by a bolt. For example, the female locking member is formed by a cavity carried by, or provided in, one face of the reservoir 10. Thus the automatic locking device is advantageously a device for mechanically locking the reservoir 10 in the second position, by a complementarity of mechanical form, of the male/female type. Alternatively, but less preferentially, the automatic locking device could for example be a magnetic automatic locking device, the first and second locking members then being able to be formed for example of permanent magnets of opposite polarities. More preferably, the first locking member 29, carried by the main body 2, forms a male locking member, while the second locking member 30, respectively carried the reservoir 10, forms a female locking member designed and configured to receive said male locking member, when the reservoir 10 is in the second position, and thus oppose a translation of the reservoir 10 towards the first position in the direction Δ of translation.

Advantageously, at least one of the first or second locking members 29, 30 is mounted movable relative to a respective surface of the main body 2 and/or the reservoir 10. Thus, the cooperation of the first or second locking members 29, 30 with each other when the reservoir 10 is in the second position advantageously results from a movement of the first locking member 29 relative to a surface of the main body 2 and/or a movement of the second locking member 30 relative to a surface of the tank 10.

Even more advantageously, the first locking member 29, carried by the main body 2, forms a male locking member which is mounted movable relative to a surface of the main body 2, while the second locking member 30 respectively carries the reservoir 10 forms a female locking member which is designed and configured to receive the male locking member and which is advantageously immobile relative to a surface of the reservoir 10 carrying the second locking member 30. Such a choice makes it possible in particular to simplify, lighten and make the tank 10 design more robust and more compact.

As such, as in the embodiment illustrated in the figures, the female locking member is advantageously formed by a cavity 37 formed in said face 26 (fixing face) of the reservoir 10. In return, said male locking member is advantageously formed by a bolt 38, which is mounted movable relative to a surface of the main body 2, and more precisely and more advantageously relative to the receiving surface 23 defined by the main body 2, enters at least one locking position, in which the bolt 38 projects from the receiving surface 23 so that the bolt 38 is received in said cavity 37 when the reservoir 10 is in the second position, and an unlocking position. Thus when the reservoir 10 is in the second position and the bolt 38 is in said locking position, the cooperation of the bolt 38 with the cavity 37 thus opposes a translation of the reservoir 10 from the second position towards the first position . Conversely, in said unlocking position, the bolt 38 authorizes a translation of the tank 10, in the direction Δ of translation from the second position towards the first position. The unlocking position therefore corresponds to a position of the bolt 38 in which the latter projects less from the receiving surface 23 than in the locking position, and in which in particular the bolt 38 does not project sufficiently from the receiving surface 23 to allow cooperation of the bolt 38 with the cavity 37. When it is in the unlocking position, the bolt 38 is therefore not capable of being received in (and of cooperating with), the cavity 37, and this same if the tank 10 is actually in said second position. Advantageously, as in the embodiment illustrated in the figures, the bolt 38 is movable, between at least said locking position and unlocking position, in a direction which is orthogonal to the direction Δ of translation of the tank 10 and which is normal to the reception surface 23.

The automatic locking device also comprises an elastic return member 39 exerting an automatic return force of the bolt 38 towards said locking position. For example, the elastic return member 39 can be a helical compression spring as illustrated by example in the figures, a leaf spring(s), or any other known and suitable elastic return member. Preferably, the surface of said face 26 of the reservoir 10 presses the bolt 37, therefore countering the automatic return force exerted by the elastic return member 39, to maintain it in said unlocking position when the reservoir 10 is in said first position then moves in translation towards said second position. In other words, the hairdressing appliance 1 is therefore advantageously designed and configured in such a way that, when the reservoir 10 is in the first position then when it moves in translation towards the second position, the bolt 38 is then arranged in contact with the surface of said face 26 of the reservoir 10 and is thus maintained in the unlocked position. Thus, the installation of the reservoir 10 by the user in the first position (while the reservoir 10 being previously separated from the main body 2) therefore advantageously leads to contact of the bolt 38 with the surface of the face 26 ( fixing face) of the tank 10, which causes a forced movement of the bolt 38 to its unlocking position. Then, while the user then manually moves the reservoir 10, in said direction Δ of translation, from the first position to the second position, the contact of the bolt 38 with the surface of the face 26 of the reservoir 10 maintains the bolt 38 in said unlocking position, the surface of the face 26 of the reservoir 10 sliding against the bolt 38. Finally, when the reservoir 10 reaches said second position, the bolt 10 is then automatically returned to the locking position by the elastic return member 39 and engages in the cavity 37 formed in the face 26 of the reservoir 10. When the reservoir 10 reaches the second position, the automatic engagement of the bolt 38 in the cavity 37 can advantageously generate a characteristic noise (typically under the effect of 'a coming into contact of the bolt 38 with a portion of the internal wall of the cavity 37, and for example with a bottom of the latter), which informs the user about the correct locking of the tank 10. The assembly and manufacture of the tank 10 are therefore particularly simple and intuitive for the user.

The locking force of the automatic locking device, that is to say the intensity of the effort which the latter exerts against the tank 10 to oppose a translation of the tank 10, in particular towards the first position, can thus be advantageously defined in particular by an adequate choice of the intensity of the automatic return force exerted by the elastic return member 39 (and for example by an adequate choice of stiffness constant in the case preferential where the latter is a spring as envisaged previously).

Preferably, as in the embodiment illustrated in the figures, the bolt 38 is rigid, that is to say substantially not elastically deformable (in normal use of the device 1). For example, the bolt 38 is made of rigid plastic material (for example polyoxymethylene (POM)). Such a rigid character of the bolt 38 contributes to reinforcing the robustness and reliability of the locking of the tank 10 in position relative to the main body 2. On the other hand, this rigid character also advantageously allows the generation of a particularly good characteristic noise. perceptible by the user when the reservoir 10 reaches the second position and the bolt 38 then engages in the cavity 37, being pushed back into said locking position under the effect of the force exerted by the return member elastic 39.

In order to allow advantageously automatic unlocking of the automatic locking device, as envisaged previously, the bolt 38 preferably has at least one face 38B which is designed and configured to cooperate with a portion of an internal wall and/an edge of the cavity 37 to cause a movement of the bolt 38 from the locking position to the unlocking position, against the automatic return force exerted by the elastic return member 39, under the effect of a force exerted by the user tending to move the reservoir 10 in translation from the second position to the first position. Advantageously, said face 38B of the bolt 38 is inclined obliquely with respect to the direction Δ of translation. Thus, the user can unlock the reservoir 10, easily and intuitively, by manually forcing the reservoir 10 to move from the second position to the first position, by applying a sufficient manual effort to counter the automatic return force exerted. by the elastic return member 39 and therefore allow release of the bolt 38 from the cavity 37. Alternatively, the bolt 37 could have for the same purposes an end portion of generally rounded shape, for example hemispherical.

As in the embodiment illustrated in the figures, and as visible in particular in Figures 5 and 13, said face 26 (fixing face) of the reservoir 10 is also advantageously provided with a protuberance 40, which is arranged along an edge of the cavity 37. Said protuberance 40 is designed and configured to come into contact with the bolt 38 and cause a movement of the latter against the automatic return force exerted by the elastic return member 39 when the reservoir 10 moves in translation from the first position to the second position. Thus, when the user manually moves the reservoir 10 in translation along said direction Δ of translation, from the first position towards the second position, and the reservoir 10 is about to reach said second position, the contacting of the bolt 38 with the protuberance 40 advantageously causes additional movement, depression, of the bolt 38 to a position which is located below said locking position, and advantageously to a position in which the bolt 38 is arranged at the level with the receiving surface 23. Thus, when the reservoir 10 actually reaches the second position, the distance which the bolt 38 then travels, when it is automatically returned to its locking position by the automatic return member, is thus more important, so that the return effect is more brutal, more rapid, than in the absence of the protuberance 40. This advantageously makes it possible in particular to facilitate and make the engagement of the bolt 38 in the cavity 37 easier and more reliable, and also advantageously contributes to increasing the noise generated by this engagement, in particular when the bolt 38 is rigid. What is more, the protuberance 40 contributes to making the attachment of the reservoir 10 to the main body 2 even more reliable by limiting the risk of involuntary disengagement of the bolt 38 from the cavity 37, for example under the effect of a shock caused by the user to the hairdressing appliance 1. As such, the bolt 38 preferably has at least one face 38A which is designed and configured to cooperate with the protuberance 40 to cause said movement of the bolt 38 against the automatic return force exerted by the elastic return member 39 when the reservoir 10 moves in translation from the first position towards the second position. To this end, said face 38A of the bolt 38 is advantageously inclined obliquely with respect to the direction Δ of translation.

According to a particularly advantageous variant, which is implemented in the embodiment illustrated in the figures and which combines the aforementioned advantages, the bolt 38 advantageously presents:
– a first face 38A, designed and configured to cooperate with the protuberance 40 to cause said movement of the bolt 38 against the automatic return force exerted by the elastic return member 39 when the tank 10 moves in translation from the first position to the second position, and
– a second face 38B, designed and configured to cooperate with a portion of an internal wall and/an edge of said cavity 37 to cause a movement of the bolt 38 from the locking position towards the unlocking position, at the therefore against the automatic return force exerted by the elastic return member 39, under the effect of a force, exerted by the user, tending to move the reservoir 10 in translation from the second position towards the first position .

According to this variant, said first and second faces 38A, 38B are advantageously inclined obliquely with respect to the direction Δ of translation. Even more advantageously, and as visible in example in the , the first face 38A is more inclined (obliquely relative to the direction Δ of translation) than the second face 38B. This thus advantageously makes it possible to facilitate the passage from the first position to the second position by overcoming the protuberance 40 and the automatic locking of the tank 10 in the second position, compared to the automatic unlocking and the passage of the tank 10 from the second position to the second position. first position.

According to this variant, and in application of the above, the second face 38B is also advantageously designed and configured to further cooperate with the protuberance 40 to cause additional movement of the bolt 38 below the unlocking position, at the against the automatic return force exerted by the elastic return member 39 when the tank 10 moves in translation from the second position towards the first position under the effect of the force exerted by the user tending to move the tank 10 to translate from the second position to the first position. This advantageously results, thanks to the protuberance 40, in the generation of a characteristic noise perceptible by the user not only during the automatic locking of the tank in the second position, but also during the automatic locking of the tank 10. In fact, the crossing of the protuberance 40 by the bolt 38 advantageously brings the bolt 38 into contact with the surface of the face 26 for fixing the reservoir 10, under the effect of the automatic return force exerted by the return member elastic 39, which thus generates a noise (which is all the more perceptible by the user as the bolt 38 is rigid, as explained previously).

As visible in example at , the bolt 38 is preferably provided with a stop 38C, which is designed and configured to come into contact with a portion of corresponding stop surface 41 of the main body 2, in order to define a maximum stroke of the movement of the bolt 38 in the direction from the unlocking position to the locking position, under the effect of the automatic return force exerted by the elastic return member 39. For example, the bolt 38 comprises a peripheral flange, which extends radially relative to in the direction of movement of the bolt 38, and which forms said stop 38C, as visible for example in Figures 16 and 17. Said corresponding stop surface portion 41 of the main body 2 is advantageously positioned inside the main body 2, facing the reception surface 23 defined by the latter, as visible at the .

In a particularly advantageous manner, as illustrated by example in , the bolt 38 is dimensioned and the stop 38C is arranged so that, when the reservoir 10 is in the second position and the bolt 38 is therefore received in the corresponding cavity 37, said stop 38C is positioned at a distance from said portion of abutment surface 41 (as visible in Figures 12 and 13). Such an advantageous configuration contributes in particular to making the operation of the reversible assembly and fixing system, and of the automatic locking device of the latter, even more reliable, by authorizing automatic compensation of possible dimensional tolerances during the manufacture of the hairdressing device. 1, but also automatic compensation for possible wear of the bolt 38 during the life of the hairdressing appliance 1. Such a configuration also advantageously has the consequence that, when the reservoir 10 leaves the second position, the elastic return member 39 tends to return the bolt 38 to a position in which the bolt 38 projects even more from the receiving surface 23 than when it is in the locking position. Thus, when the user manually moves the tank 10 from the second position to the first position during the operation of disassembly and separation of the tank 10, the automatic return of the bolt 38 advantageously causes a lifting, a spreading, of the tank 10 relative to the main body 2, which thus facilitates handling of the reservoir 10 by the user with a view to removing it.

Preferably, the automatic locking device comprises a plurality of first locking members 29 and a plurality of corresponding second locking members 30. It is thus possible to make the attachment of the reservoir 10 to the main body 2 even more reliable, or for example to design the automatic locking device so as to facilitate the integration into the main body 2 of certain internal components of the hairdressing appliance 1 This further advantageously makes it possible to increase the noise, mentioned above, generated during assembly and fixing, and/or during disassembly and separation, of the tank 10 relative to the main body 2.

For example, the automatic locking device advantageously comprises, as in the embodiment illustrated in the figures, a pair of first locking members 29 and a pair of corresponding second locking members 30. Said first locking members 29 then preferably form a pair of said bolts 38, as male locking members mounted movable relative to a surface of the main body 2. Respectively, said second locking members 30 then preferably form a pair of said cavities 37, as female locking members. The first locking members 29 are then advantageously arranged spaced apart from each other, and preferably in a secant direction, more preferably orthogonal, to the direction Δ of translation of the reservoir 10. Reciprocally, the second locking members 30 are also advantageously arranged spaced apart from each other, and preferably in a secant direction, more preferably orthogonal, to the direction Δ of translation of the reservoir 10.

The automatic locking device can then comprise a single elastic return member 39, which is therefore common to the two bolts 38. Alternatively, as in the embodiment illustrated in the figures, the automatic locking device can instead comprise two return members elastic 39 to each automatically return one of said bolts 38 to said locking position. To simplify the design of the automatic locking device, the bolts 38 are advantageously identical to each other, and said elastic return members 39 are identical to each other where appropriate (for example, two helical springs compression of the same dimensions and the same stiffness).

According to an alternative variant (not illustrated), less preferential in terms of robustness of the locking, the first male locking member(s) could be formed by an elastically deformable stud (for example made of material elastomer, and for example rubber) arranged projecting from the receiving surface 23. The female locking member(s) could then be formed by a cavity formed in said face 26 (fixing face ) of tank 10.

Preferably, the main body 2 of the device 1 comprises a first cover element 42 which defines said receiving surface 23 for the reservoir 10, that is to say a surface portion of which forms said receiving surface 23, and a second cover element 43 which is secured to said first cover element 42. The respective external faces of the first and second cover elements 42, 43 thus advantageously define at least part of a visible external envelope of the main body 2. By example, the first and second cover elements 42, 43 are made of plastic. Secured to one another, the first and second cover elements 42, 43 together define a housing within which is arranged the elastic return member 39 of the automatic locking device of the reversible assembly and fixing system of the tank 10 to the main body 2.

The hairdressing appliance 1 advantageously comprises a support part 44 against which the elastic return member 39 is arranged in abutment to exert said automatic return force of the bolt 38 towards said locking position. Said support piece 44 is distinct from said first cover element 42, and is secured to the latter, definitively or preferably in a detachable manner (for example, by screwing), to maintain the elastic return member 39 secured to the first cover element 42. On the other hand, the support part 44 is distinct and independent of the second cover element 43. The support part 44 is therefore neither formed by the second cover element 43, nor mechanically connected directly to the latter. The manufacture of the hairdressing appliance 1 is thus advantageously facilitated, to the extent that it is thus possible to install the elastic return member 39 in position relative to the first cover element 42 which defines said receiving surface 23, then to maintain the elastic return member 39 secured to the first cover element 42 by fixing the support piece 44 to the first cover element 42, before subsequently securing the second cover element 43 to the first cover element 42. thus avoids a risk of involuntary movement of the elastic return member 39 during the assembly and securing of the second cover element 43 to the first cover element 42.

Preferably, the first and second cover elements 42, 43 are secured to one another in a detachable manner, for example by screwing and/or by reversible elastic interlocking. In this case, the repair and/or maintenance of the hairdressing appliance 1 is facilitated to the extent that the second cover element 43 can then be separated from the first cover element 42 to access the interior of the housing, in which can be arranged, in addition to the elastic return member 39, a certain number of mechanical, electrical or even hydraulic components necessary for the operation of the hairdressing appliance 1 (as visible for example in Figures 8, 10, 14 and 15 ), and this without risking involuntary movement, a fall, or even loss, of the elastic return member 39.

In the scenario mentioned above where the automatic locking device comprises a pair of said elastic return members 39 (that is to say two elastic return members 39 each to automatically return a respective bolt 38 to said locking position ), the hairdressing appliance 1 then preferably comprises a single support piece 44, against which said elastic return members 39 are therefore both arranged in abutment to each exert an automatic return effort of the bolts 38 towards their position respective locking mechanism. This makes it possible to simplify the design and manufacture of the hairdressing device 1 by limiting the number of parts thereof.

For example, when the elastic return member is a helical compression spring, as in the embodiment in the figures and as illustrated in particular in Figures 12, 13, 16 and 17, the first cover element 42 can advantageously comprise a well 45, which projects from an internal face portion of the first cover element 42, which is opposite to an external face portion of the first cover element 42 defining said receiving surface 23. The helical compression spring is housed longitudinally in the well 45. The well 45 has a bottom, arranged opposite an opening of the well 45, and which is provided with a through hole via which the bolt 38 is slidably mounted to project from the receiving surface 23 in the manner mentioned above. The bolt 38 may have a coupling portion via which the bolt 38 is connected in contact with the helical compression spring, at a first end of the latter, said coupling portion being housed in the recess axial of the helical compression spring. As already mentioned previously, the bolt 38 is preferably provided with a stop 38C, which is designed and configured to come into contact with a portion of corresponding stop surface 41 of the main body 2, in order to define a maximum travel of the movement of the bolt 38 in the direction from the unlocked position to the locked position. For example, the bolt 38 comprises a peripheral flange, which extends radially relative to the direction of movement of the bolt 38, and which forms said stop 38C. Advantageously, the stop 38C of the bolt 38 is positioned in the well 45, and the corresponding portion of stop surface 41 is formed by a portion of the surface of the bottom of the well 45. The support piece 44 then advantageously forms a cover of closing the opening of the well 45, a second end of the helical compression spring then being arranged in contact against a face of the support part 44 oriented towards the inside of the well 45. A seal (not illustrated in figures) can advantageously be arranged between the support part 44 and the well 45, to prevent liquid which would infiltrate into the well 45 through the hole passing through the bottom of the well 45 from penetrating inside the housing through the opening of the well 45. The support part 44 can be provided with one or more fixing ears 44A, by means of which the support part 44 is secured in a detachable manner to the first cover element 42, by example using screws. For example, the support part 44 is made of plastic.

For example, when the automatic locking device comprises two bolts 38 and two elastic return members 39 which are helical compression springs, as in the embodiment in the figures and as visible in particular in Figures 12, 15, 16 and 17 , the first cover element 42 can advantageously comprise two distinct wells 45, each conforming to the above and receiving one of the helical compression springs. As envisaged previously, the support part 44 can advantageously constitute a single part, which forms covers for closing the opening of each of the wells 45.

This being explained, it should be noted that could constitute an invention in its own right, a hairdressing device comprising a vaporization device for generating a flow of vaporized liquid, a removable liquid reservoir for supplying said vaporization device, a main body, and a reversible assembly and fixing system for the tank to said main body,
said reversible assembly and fixing system comprising an automatic locking device to immobilize the tank relative to the main body,
said automatic locking device comprising:
– at least one male locking member carried by the main body and at least one female locking member carried by the tank, the male locking member being movably mounted at least between a locking position in which the male locking member is arranged in the female locking member, and an unlocking position in which the male locking member is arranged outside the female locking member,
– and an elastic return member to automatically return the male locking member to said locking position,
said main body comprising a first cover element intended to receive the tank, and a second cover element which is secured, preferably in a detachable manner, to said first cover element, said first and second cover elements together defining a housing within on which said elastic return member is arranged,
the device comprising a support part against which the elastic return member is arranged to abut to exert an automatic return force of the male locking member towards said locking position, said support part being distinct from said first hood element and being secured to the latter, preferably in a detachable manner, to maintain the elastic return member secured to the first hood element, said support part being distinct and independent of the second hood element.

We understand from the preceding description that such a hairdressing device has the advantage of being particularly easy to manufacture, and of also advantageously allowing it to be particularly easy to repair and maintain.

Such a hairdressing device could obviously also include all or part of the characteristics of the device previously described in detail in connection with the appended figures.
