Description

Technical area

The present invention relates to the field of hairdressing devices and preferably to the field of hairdressing devices vaporizing liquid towards a strand of hair, such as for example steam hairdressing devices.

More specifically, the invention relates to the field of hairdressing appliances comprising a vaporization device intended to diffuse vaporized liquid towards a strand of hair, a main body, a removable reservoir and intended to contain a liquid to be vaporized and to be assembled with the main body in order to be connected with the vaporization device to supply the latter with liquid to be vaporized.

The invention also relates to the field of reservoirs for hairdressing appliances, and more particularly to reservoirs intended to contain a liquid to be vaporized and to be assembled with a main body of a hairdressing appliance, said reservoir being intended to be connected with a vaporization device of the hairdressing appliance adapted to vaporize the liquid and diffuse it towards a strand of hair

Prior art

We know of many hairdressing devices having a function of vaporizing liquid towards the hair. Indeed, we know that spraying a liquid on a strand of hair during styling improves the effectiveness of the styling operation and the result.

In order to be able to carry out this vaporization, known hairdressing appliances are equipped with a reservoir to contain the liquid to be vaporized. This reservoir is generally removable from the main body of the hairdressing appliance in order to facilitate its filling operation. Thus, the user must frequently, generally at least once before each styling operation, remove the reservoir from the main body of the appliance, fill it with liquid (for example with water), then assemble the reservoir with the main body of the hairdressing appliance in order to supply the latter with liquid to be vaporized.

These hairdressing devices generally give satisfaction to their users, in particular with regard to 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 tank with the main body of the device.

Indeed, if the reservoir is not assembled correctly with the main body of the device, there may be liquid leaks during the styling operation. These risks are particularly increased due to the fact that the hairdressing devices in question are intended to be handled by hand by the user and to undergo numerous movements linked to hairstyling operations. Additionally, the reservoir may accidentally become detached from the styling appliance. These leaks or this detachment can cause inconvenience for the user ranging from simple wetting of their clothes for example, to the risk of electrocution, the hairdressing devices in question generally being electrical devices.

In order to limit this type of risk, different principles have been proposed for attaching the tank to the main body of the hairdressing appliance.

A first known solution consists, as can be seen for example on numerous marketed devices or as illustrated by the document WO2017008413 , to assemble the tank on the main body of the hairdressing appliance by sliding: the tank must then slide within the main body to be able to be assembled or disassembled. The holding of the reservoir is then partly ensured by friction according to the direction of sliding. However, this solution proves to be particularly restrictive for the user who, when he wishes to assemble or disassemble the reservoir of his hairdressing appliance, must firmly grasp the main body of the hairdressing appliance with one hand, and firmly grasp the tank with his second hand, then exert a significant relative movement between their elements to disassemble or assemble them. This operation therefore requires both hands of the user as well as a significant movement, both in terms of amplitude and force (to overcome the friction force). In addition, as assembly and disassembly operations progress, the parts in friction with each other will wear out, play will appear, and the reliability of the assembly will decrease over time, which risks causing accidental disassembly over time.

Another known solution consists of equipping the main body of the device with an element whose elastic deformation makes it possible to ensure the assembly or disassembly of the tank. It is therefore the elasticity of this element, generally a tab, which will allow both to ensure that the tank is maintained in the hooked position, but also to allow the user, by forcibly manipulating the tank, to deform elastically this tab during assembly or disassembly operations. This solution turns out to be particularly unreliable with regard to maintaining the tank and presents risks of accidental disassembly. In addition, this solution is not very durable over time since, as the assembly and disassembly operations progress, the tab will wear out and the assembly will become loose, which increases the risk of accidental disassembly. In addition, the risk of rupture due to fatigue of the tongue, due to deformation, is great, and therefore the tank can no longer be held by the main body. The reliability and durability of this solution therefore appears limited.

There is therefore a need to improve existing devices, particularly in terms of assembling the tank with the main body of the device.

Presentation of the invention

The present invention aims to overcome the aforementioned drawbacks.

An objective of the invention is to provide a reservoir for a hairdressing device which is particularly reliable and robust.

An objective of the invention is to propose a hairdressing device which is particularly intuitive to handle and ergonomic, in particular during operations of assembly or disassembly of the reservoir with the main body of the hairdressing device.

An objective of the invention is to provide a hairdressing device which is particularly compact and light.

These objectives are achieved using a reservoir intended to contain a liquid to be vaporized and to be assembled with a main body of a hairdressing device, said reservoir being intended to be connected with a vaporization device of the device hairdressing device designed to vaporize the liquid and diffuse it in the direction of a strand of hair, characterized in that the reservoir comprises a movable hooking device comprising at least one hooking means designed to correspond with at least one means of complementary hooking belonging to the main body so as to hook the tank with the main body, said mobile hooking device being movable between a first position ensuring the hooking of the tank with the main body and a second position allowing a user to assemble or disassemble the tank with the main body.

These objectives are also achieved using a hairdressing device comprising a vaporization device designed to vaporize the liquid and diffuse it towards a strand of hair, a main body, a removable reservoir and intended to contain a liquid to be vaporized and to be assembled with the main body in order to be connected with the vaporization device to supply the latter with liquid to be vaporized, characterized in that the reservoir conforms to the previous description.

The invention therefore concerns two distinct products, in this case a reservoir for a hairdressing device and a hairdressing device, having a link between them since the first is designed to be connected to the second.

Preferably the liquid is water. However, the invention is not limited to this particular liquid and the liquid can for example be oil, a cosmetic product, or any other liquid product which could be projected onto the hair in order to give it a treatment or in order to to improve the efficiency of the styling operation. The liquid may optionally be a mixture of water and another product, such as for example a cosmetic product.

The expression “vaporize” can be understood here in its broadest sense. Thus, it designates any type of liquid projection, whatever its nature, its shape or whatever its state. For example, the liquid can be vaporized by being dispersed in a multitude of fine droplets, preferably of microscopic size, for example like a mister.

Preferably, the expression “vaporize” can also be understood in its strict physical sense, that is to say, by an operation resulting in the transformation of a liquid into vapor. In other words, the expression vaporization can imply a change of state: the liquid goes from the liquid state to the gaseous state. For example, in the preferential case where the liquid is water, this transformation of state, that is to say this vaporization, takes place when the liquid reaches the temperature of 100°C under normal atmospheric pressure.

By tank designates any type of container capable of containing a liquid in a sealed manner, and preferably water. Preferably the capacity of the reservoir is between 5 mL and 500 mL, and advantageously between 15 mL and 100 mL. Preferably the tank is made of plastic. Advantageously, the tank comprises an upper casing and a lower casing assembled together in a non-removable manner (for example by gluing or welding).

The tank is removable, which means that it can be assembled or disassembled (or hooked and unhooked) at will from the main body of the hairdressing appliance without damage to either the tank or the main body.

In particular, the tank can occupy a hooked position. In this position, the reservoir is fixed to the main body of the hairdressing appliance: the reservoir is then integral with the main body, advantageously connected in a sealed manner with the main body. This hooked position allows the reservoir to deliver the liquid it contains to the hairdressing device so that the vaporization device vaporizes the liquid then diffuses it towards a strand of hair.

The tank can also occupy an unhooked position. In this position it is not attached to the main body. Preferably, the tank is independent of the main body and can then be freely and easily manipulated by the user, for example to fill the tank, to clean it, etc.

By mobile hanging device, we preferably mean any mobile device or means, that is to say movable in several positions, allowing, among other things, to hang (that is to say to fix) the reservoir with or on the main body of the hair styling appliance. To this end, the mobile hooking device of the invention comprises at least one hooking means designed to correspond with at least one complementary hooking means belonging to the main body so as to hook the tank with the main body. Thus, two complementary hooking means are used: on the one hand, a hooking means on board the mobile hooking device, preferably a male hooking means, and, on the other hand, a complementary hooking means embedded on the main body of the hairdressing appliance, preferably a female complementary hooking means. Said at least one hooking means of the mobile hooking device and at least one complementary hooking means of the main body will then cooperate with each other to ensure the hooking, that is to say the fixing, between the tank and the main body. Preferably, the mobile hooking device comprises two hooking means designed to correspond with two complementary hooking means belonging to the main body so as to hook the tank with the main body at two distinct points, which reinforces the mechanical resistance of the hooking.

The hooking device of the invention is movable between a first position ensuring the hooking of the tank with the main body and a second position allowing a user to assemble or disassemble the tank with the main body. In other words, the first position of the mobile hooking device corresponds to the hooked position of the tank as defined previously. The second position of the mobile attachment device corresponds to the unhooked position of the tank as defined previously. Thus, thanks to the mobile hooking device of the invention, it is possible for the user to easily and quickly control the passage of the tank from its hooked position to its unhooked position, or vice versa. In addition, the mobile attachment device is on board the tank which allows the user to be able to operate it with the same hand as the one gripping the tank. The mobile hooking device allows the tank to be moved from its hooked position to its unhooked position according to the user's wishes. It is thus possible for the user to hook or unhook the tank with one hand. In particular, only a voluntary action by the user on the mobile hooking device (he must move it between its two positions) makes it possible to move the tank from its hooked position to its unhooked position, which avoids any accidental unhooking of the reservoir of the main body of the hairdressing appliance. This significantly increases the comfort and safety of using the hairdressing device.

By hairdressing device, we mean any type of device allowing a user to carry out a hairdressing operation on hair (or possibly on hair in the case of animals for example). For example, the hairdressing device can be a straightener making it possible to straighten the hair, a curler (or "curler" according to the English term) making it possible to make curls or waves, or a versatile device making it possible to create several different formats.

According to one embodiment, the hairdressing appliance comprises a first arm connected to a second arm by a hinge so as to form a clamp movable between an open position and a closed position. The open position allows the user to insert a strand of hair inside the device, while the closed position allows the user to apply pressure to the hair, and preferably heat, to perform a shaping of the latter, generally a smoothing. Thus, the device forms a straightening pliers, a well-known device as such which will not be further detailed here. In particular, this type of device comprises in particular at least one heating treatment surface, and preferably two, arranged at the end of an arm (or each arm) and intended to come into contact with hair to transfer heat to it.

The main body preferably designates the part of the hairdressing appliance which is designed to receive the reservoir. According to one embodiment, the main body comprises the vaporization device, and advantageously the first and second arms. However, one could imagine an embodiment where the hairdressing device comprises a main body containing the removable reservoir and a secondary body comprising in particular the vaporization device, and advantageously the first and second arms. The main body and the secondary body would in this case be connected together by a cord designed to convey the liquid contained in the reservoir of the main body to the secondary body.

Advantageously, the main body comprises a recess of a shape complementary to at least part of the shape of the tank and designed to receive at least part of the tank when the latter is in the hooked position, said recess comprising said at least one means of additional hanging. Thus, the reservoir is at least partially located inside the main body of the hairdressing appliance which makes it possible, on the one hand to limit the overall size of the hairdressing appliance, and on the other hand to ensure excellent retention of the tank in its hooked position.

According to a preferred embodiment, the mobile hooking device comprises at least one button intended to be directly actuated by the user to move the mobile hooking device from its first position to its second position or vice versa. This makes the use of the mobile attachment device and therefore of the hairdressing appliance particularly simple and intuitive. Advantageously, the button is a push button designed to be actuable by a finger of the user's hand. Preferably, the mobile attachment device comprises two buttons, which makes it possible to distribute the efforts and therefore to improve the ergonomics of the reservoir and of the hairdressing appliance. Advantageously, the two buttons are coaxial and oriented in opposite directions so that they can be actuated by the user using a pinching movement between two fingers, for example between the thumb and the index finger. Indeed, it is a natural and intuitive movement for humans who seek to manipulate an object.

According to an advantageous embodiment, the mobile attachment device is movable in translation relative to the tank. In other words, the movement of the mobile attachment device will cause its translation relative to the tank which will remain fixed. This mode of movement of the mobile hanging device makes it possible to reconcile simplicity, robustness and ergonomics. Indeed, thanks to this embodiment, the user can place the reservoir in the palm of his hand while operating with one or more fingers of this hand the movable hooking device in translation.

Preferably, the tank extends longitudinally along a first axis, and said mobile attachment device is movable in translation relative to the tank along a second axis perpendicular to said first axis. The fact of having a translation movement perpendicular to the longitudinal axis of the tank makes it possible to obtain a particularly ergonomic tank to the extent that a minimum of effort is necessary to hold the tank in the hand. Indeed, the longitudinal axis of the tank is placed in the palm of the hand, giving the tank excellent support, and the translation movement of the mobile attachment device, perpendicular to the longitudinal axis, is then remarkably well oriented relative to a movement of the thumb and/or index finger of the hand holding the tank.

According to this advantageous embodiment, the mobile attachment device comprises a translation guide device, the reservoir comprises a complementary translation guide device, said translation guide device and complementary translation guide device cooperating with each other in a manner to guide the mobile attachment device in translation within the tank. Thus, the translation movement of the mobile attachment device is limited to a single translation which is guided by the tank itself. This guarantees easy movement, good ergonomics and intuitiveness for the user who cannot make any incorrect manipulations.

Still according to this advantageous embodiment, preferably the mobile attachment device comprises a first stopping device in the first position, the tank comprises a first complementary stopping device in the first position, said first stopping device in the first position and first complementary stopping device in the first position cooperating with each other so as to prevent the translation of the mobile attachment device beyond said first position. Thus, the translation movement of the mobile attachment device is limited by the tank itself so as not to exceed the first position. This guarantees easy movement, good ergonomics and intuitiveness for the user who cannot make any incorrect manipulations. Furthermore, advantageously, the mobile attachment device comprises a second stopping device in the first position, the tank comprises a second complementary stopping device in the first position, said second stopping device in the first position and second device complementary stop in the first position cooperating with each other so as to prevent the translation of the mobile attachment device beyond said first position. Thus, the translation movement of the mobile attachment device is doubly limited by the tank itself. This guarantees good mechanical resistance, with two stopping points and in particular eliminates any risk of accidental disassembly of the mobile attachment device in relation to the tank.

Still according to this advantageous embodiment, preferably the mobile attachment device comprises a stopping device in the second position, the reservoir comprises a complementary stopping device in the second position, said stopping device in the second position and complementary device d stopping in the second position cooperating with each other so as to prevent the translation of the mobile attachment device beyond said second position. Thus, the translation movement of the mobile attachment device is limited by the tank itself so as not to exceed the second position. This guarantees easy movement, good ergonomics and intuitiveness for the user who cannot make any incorrect manipulations. Finally, when the two preferred constructions above are combined within this advantageous embodiment, the movement of the mobile attachment device is completely limited by and within the tank to a translation movement between the first and second position. This guarantees easy movement, good ergonomics and intuitiveness for the user who cannot make any incorrect manipulations.

According to one embodiment, the first position of the mobile attachment device is a rest position. In other words, the mobile attachment device is naturally, or by default, kept stable in its first position, that is to say in the position which guarantees the attachment of the tank with the main body of the hairdressing device. This significantly improves the safety of use of the device since, without action on the part of the user, the tank remains firmly attached to the main body of the hairdressing device. To this end, preferably, the mobile attachment device comprises an elastic return device, said elastic return device preferably being a helical spring which guarantees reliability, robustness and low construction cost. However, one could of course imagine any other means suitable for making the first position a rest position, such as for example a ferromagnetic device. In the preferential case where the movable hooking device comprises two buttons, advantageously, the elastic return device is arranged between the two buttons so as to push back, to move apart, the latter. This makes it possible to obtain a simple, inexpensive, reliable and very efficient construction from a mechanical point of view. Preferably, the mobile attachment device comprises a housing designed to accommodate the elastic return device. This housing then makes it possible, on the one hand to limit the bulk of the mobile attachment device by integrating the elastic return device, and on the other hand to ensure the guidance and maintenance of said elastic return device during movements , which will improve overall reliability. Advantageously, when the mobile hooking device is in its second position, the two buttons are in contact which makes it possible to form another stopping device in the second position in order to absorb the forces applied by the user on the buttons. This reinforces the mechanical strength of the mobile attachment device and the reliability of the tank.

According to one embodiment, the tank comprises a fixed additional hooking device designed to cooperate with a complementary additional hooking means belonging to the main body when the tank is in the hooked position. Thus, two other complementary attachment means can be implemented to improve the attachment of the reservoir to the main body of the hairdressing appliance: on the one hand an additional fixed attachment device, i.e. say no mobile and no deformable, preferably a male hooking device, embedded on the tank, and on the other hand by an additional complementary hooking means embedded on the main body of the hairdressing appliance, preferably a complementary female hooking means. Said additional fixed hooking device and complementary additional hooking means will then cooperate with each other to ensure the hooking, that is to say the fixing, between the tank and the main body. Preferably, said fixed additional hooking device and complementary additional hooking means are arranged parallel to the longitudinal axis of the tank while said at least one hooking means and complementary hooking means are arranged perpendicular to the longitudinal axis of the tank. This makes it possible to properly distribute the attachment points between the tank and the main body and therefore to improve the mechanical resistance of the attachment.

According to one embodiment, the tank comprises at least one guide device designed to cooperate with at least one complementary guide device of the main body when the tank is in the hooked position. In other words, two complementary guiding devices are implemented to improve the attachment of the tank to the main body of the hairdressing appliance but also to facilitate the assembly and disassembly operations of the tank by guiding the movement of the latter: on the one hand, a guiding device, preferably female, embedded on the tank, and on the other hand a complementary guiding device, preferably male, embedded on the main body, and preferably included in the recess.

Description of embodiments

The embodiment of the invention illustrated by the different figures is an embodiment in which the hairdressing appliance which is the subject of the invention is a steam straightener. Consequently, tank 2, also the subject of the invention, is a tank for a steam straightener. However, one could perfectly imagine, without departing from the scope of the invention, other embodiments, such as for example a steam curler (or curler according to the common English expression).

As we can see in the figure 1 , the hairdressing appliance comprises a first arm 11 connected to a second arm 12 by a hinge 13 so as to form a clip movable between an open position and a closed position. The first and second arms 11, 12 constitute gripping means for the user's hand. To this end, they preferably form, at least over part of their length, a handle forming a gripping area. The hairdressing appliance is shown in the closed position in the figure 1 . The hinge 13 is then arranged substantially at the end of said first and second arms 11, 12. The architecture and operation of this type of hairdressing appliance are well known as such, so that they will not be more detailed here. We know for example that each of said first and second arms 11, 12 comprises a heating treatment surface intended to be in contact with the hair. These treatment surfaces are arranged at the end of each of said first and second arms 11, 12, opposite the hinge 13. The hinge 13 is generally an axis around which said first and second arms are mounted.

As illustrated by figure 1 and the figure 2 , the hairdressing appliance comprises a main body 1 designed to accommodate a reservoir 2 as will be detailed later. In other words, the tank 2 is intended to be assembled with the main body 1. According to the illustrated embodiment, the main body 1 comprises said first and second arms 11, 12. But one could also imagine another mode of alternative embodiment where the hairdressing appliance would comprise a secondary body distinct from the main body 1 which accommodates the reservoir 2. The secondary body could then comprise said first and second arms 11, 12 and said hinge 13. The main body 1 and the secondary body would then be connected together by a cord to convey the liquid from the reservoir 2 of the main body 1 to the secondary body, and more precisely to the first arm 11 for example.

As can be seen on the figure 2 , advantageously, the main body 1 comprises a recess 111, that is to say a space hollowed out within the main body 1, the shape of which is complementary to at least part of the shape of the reservoir 2. In d In other words, the recess 111 forms a hollow cavity for at least part of the tank 2. The recess 111 is thus designed to receive at least part of the tank 2 when it is in the hooked position, as will be detailed afterwards.

Preferably, the main body 1, or more precisely the recess 111, comprises at least one complementary guide device 114, and advantageously two complementary guide devices 114, as shown in figure 2 . Said at least one complementary guide device 114 can then take the form of a half circular pin.

The hairdressing appliance comprises a reservoir 2 intended to contain a liquid to be vaporized, such as preferably water. Tank 2 is removable, that is to say that tank 2 can be removed or disassembled from the hairdressing appliance, as can be seen in the figure 2 which illustrates the main body 1 of the hairdressing appliance once the tank 2 has been dismantled. The reservoir 2 is therefore intended to be assembled with the main body 1 of a hairdressing appliance.

Tank 2 can occupy a hooked position, as can be seen in the figure 1 , in which it is integrated into the main body 1 of the hairdressing appliance, precisely by being arranged at least partially inside the recess 111. This makes it possible to offer a particularly compact hairdressing appliance with the reservoir integrated into the first arm 11. The attached position of the reservoir 2 corresponds to an operating position of the hairdressing appliance.

Tank 2 can also occupy an unhooked position as can be seen on the figures 2 to 8 , in which it is dissociated and independent from the main body 1 of the hairdressing appliance. When the tank 2 is in the unhooked position, it is then possible, for a user, to fill the latter, in particular after having removed a filling cap 26 visible to the figures 5 And 6 . More precisely, as we can see in the Figure 4 , the filling cap 26 comprises a filling port cap 261, intended to sealingly seal a filling port of the tank 2, and a vent port cap 262 intended to sealtightly seal a tank vent port when filling. Indeed, in order to facilitate the filling operation, more precisely to guarantee that tank 2 is maintained at atmospheric pressure when filling, tank 2 is equipped with two orifices: one of larger diameter intended to receive the liquid, the other of smaller diameter intended to ensure ventilation even if the filling orifice is entirely obstructed by the liquid or by a funnel or any other filling pipette.

Advantageously, as can be seen in the Figure 3 , the reservoir extends longitudinally along a first axis XX', that is to say that the reservoir 2 generally has an elongated shape, like a substantially rectangular shape, the angles being rounded. Indeed, this longitudinal shape is particularly adapted to allow the insertion of the reservoir 2 into the main body 1 and more particularly into the first arm 11 as shown in figure 1 while maximizing the capacity of the tank 2. Preferably, the first arm 11 extends parallel to the first axis X-X'. Advantageously, the first arm 11 extends along the first axis X-X'. In this advantageous case, as illustrated, the tank 2 can then extend over more than half the length of the first arm 11 which makes it possible to maximize the capacity of the tank 2. The tank 2 is then entirely integrated into the first arm 11 and thus constitutes a gripping area for the user's hand.

The reservoir 2 also preferably comprises a connection device 25 visible on the Figure 5 intended to correspond with a complementary connection device 15 visible on the figure 2 and located in the main body 1, and more precisely in the recess 111. As can be seen in these figures, the connection device 25 is a male connection device, in this case a portion of tube projecting from the reservoir 2, while the complementary connection device 15 is a female connection device, in this case an orifice. When the tank 2 occupies its hooked position, said connection devices 25 and complementary connection device 15 cooperate in a sealed manner in order to allow the liquid contained in the tank 2 to supply the main body of the device 1, and more precisely a vaporization device as will be detailed later. Preferably, the connection device 25 is arranged at a longitudinal end of the tank 2, as can be seen in the figure 5 , and extends longitudinally parallel to the first axis X-X'.

As can be seen on the figure 4 , the reservoir 2 advantageously comprises a suction pipe 251 connected to the connection device 25 in a sealed manner. The suction pipe 251 extends freely inside the tank 2 and comprises at its free end a suction end 252 whose mass is greater than that of the suction pipe 251. This allows the pipe to aspiration 251 to be carried by gravity where the The liquid is itself carried by gravity during the movements of the hairdressing appliance. This guarantees good suction of the liquid inside tank 2, whatever its filling level and its position in space. The suction pipe 251 is free inside the tank 2, that is to say it is flexible and can move inside the tank 2. Associated with the suction end 252 weighted, this makes it possible to solve the problem of certain current tanks which do not allow the total suction of the liquid: in other words it is impossible to empty them, the suction becoming impossible for example when the quantity of water has halved. This would then result in a lack of autonomy of the device equipped with the tank.

The tank 2 also preferably comprises a ventilation device 27 visible at the figures 4 to 6 and designed to, on the one hand prevent the liquid from escaping from the tank 2, and on the other hand maintain the tank 2 at atmospheric pressure. This venting device 27 makes it possible to solve the following technical problem. When the liquid is sucked through the suction pipe 251, the amount of liquid inside the tank 2 decreases. However, tank 2 is sealed so that the quantity of liquid sucked cannot be replaced by air. This results in the creation of a depression inside the tank 2 as the liquid is suctioned. After a certain time, the depression is so great that it becomes impossible to suck out the liquid. It then becomes impossible to suck up all of the liquid contained in tank 2, which limits the autonomy of the hairdressing appliance equipped with the tank.

The venting device 27 makes it possible to counter this phenomenon by allowing air to penetrate inside the tank 2 as the quantity of liquid inside the tank 2 decreases while by preventing the liquid from leaving tank 2.

As can be seen on the Figure 4 , the venting device 27 comprises a valve in the shape of an umbrella or mushroom. 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 and therefore to prevent the liquid from escaping from tank 2. On the other hand, when the pressure decreases inside the tank 2, the external atmospheric pressure pushes the foot of the valve despite the weight of the liquid, which allows air to enter inside tank 2. Once the pressure inside tank 2 is balanced with the external (atmospheric) pressure, the valve returns to its initial position thanks to the weight of the liquid as explained previously.

As we can see in figures 3 And 4 , the tank 2 comprises an upper casing 21 and a lower casing 22 which are connected together in a watertight and advantageously definitive manner, that is to say cannot be dismantled, for example by gluing or welding. Such an assembly makes it possible to solve the problem of mounting the tank 2 by considerably facilitating, or even simply allowing, the installation of the various components inside the tank, and in particular the installation of the suction pipe 251 described previously .

As will be understood, the devices described above, and in particular the suction pipe 251 and the venting device 27 each make it possible to solve a particular technical problem and can in this respect constitute inventions in as such.

As can be seen on the figure 5 and in more detail on the Figure 7 , the tank 2 advantageously comprises a guide frame 23 which itself preferably comprises different bars making it possible to ensure different guiding and hooking functions as will be detailed later. The guide frame 23 is advantageously located at a longitudinal end of the tank 2, preferably opposite the connection device 25.

The hair styling apparatus includes a vaporization device designed to vaporize the liquid and diffuse it toward a strand of hair. The vaporization device can for example comprise a vaporization chamber in which, under the effect of heat, the liquid contained in the reservoir 2 is transformed into vapor. The steam is then diffused towards a strand of hair, for example via distribution orifices. Such a device is well known as such and will therefore not be detailed further here. Another vaporization device can for example be a misting system which will transform the liquid into fine droplets like a mister, without going through a change in state of the liquid.

Thus, the reservoir 2 is intended to be connected with the vaporization device of the hairdressing appliance designed to vaporize the liquid and diffuse it towards a lock of hair. Reservoir 2 will then supply the latter with liquid to be vaporized. Preferably the connection is waterproof and is in particular carried out by means of the connection device 25 and the complementary connection device 15. The hairdressing appliance, and more preferably, the main body 1 can also include a flow generation device, such as a pump for example, and preferably a peristaltic pump which makes it possible to suck up the liquid contained in the reservoir, thanks to the suction pipe 251 to convey the liquid to the vaporization device.

According to the invention, the tank 2 comprises a mobile attachment device 3 as can be seen on the figures 1 , 3 , 4 , 6 , 8 . In other words, the mobile hooking device 3 is on board the tank 2, that is to say that the mobile hooking device 3 is integral with the tank 2. This allows better ergonomics for the user of the reservoir 2, and therefore of the hairdressing appliance, to the extent that it is possible to simultaneously manipulate the reservoir 2 and the mobile attachment device 3 with one hand.

As can be seen on the Figure 10 , the mobile hooking device 3 comprises at least one hooking means 333. More precisely, the mobile hooking device 3 preferably comprises a foot 33 which itself has at its end a hook forming a rib which projects from the foot 33 and intended to hang with a complementary piece; said rib then forming the hooking means 333. In other words, the hooking means 333 is a male hooking means whose shape is substantially rectangular. Advantageously, as illustrated, the mobile attachment device 3 comprises two attachment means 333 which makes it possible to multiply the attachment points between the tank 2 and the main body 1 and therefore to reinforce the mechanical resistance of the attachment. The two attachment means 333 are advantageously symmetrical with respect to a median plane P perpendicular to the first axis XX' of the tank as can be seen in the Figure 10 .

Said at least one hooking means 333 is designed to allow the tank 2 to be hooked with the main body 1, that is to say to maintain the tank 2 in the hooked position. Preferably, the hooking means 333 is rigid, that is to say it cannot deform. This characteristic makes it possible to guarantee the mechanical resistance of the connection between the tank 2 and the main body 1 and thus to avoid any risk of accidental disconnection. Furthermore, unlike the currently known tank hooking techniques which operated on the basis of an elastic deformation of such a hooking device, the rigidity of the hooking means 333 of the invention makes it possible to guarantee the mechanical resistance of hanging over time, that is to say even after numerous uses. In fact, the risk of rupture of the attachment means 333 due to fatigue is eliminated. The reliability and longevity of the attachment means 333 and therefore of the reservoir 2 and therefore of the hairdressing appliance is thus increased.

As can be seen on the figure 2 , the main body 1, and more particularly the recess 111, comprises at least one complementary hooking means 112. The latter is designed to be complementary to the hooking means 333, that is to say to cooperate with this last so as to ensure the attachment of tank 2. As can be seen in the figure 2 , the complementary hooking means 112 is preferably a female hooking means, comprising for example a cavity of substantially rectangular shape. This complementary hooking means 112 will then receive the male hooking means 333 to ensure hooking. The preferably substantially rectangular shapes of said hooking means 333 and complementary hooking means 112 make it possible to distribute the mechanical forces over a certain length which improves the mechanical resistance, in particular to tearing, of the hooking of the tank 2 with the main body 1. Thus, said at least one hooking means 333 is designed to correspond with said at least one complementary hooking means 112 belonging to the main body 1 so as to hook the tank 2 with the main body 1. Preferably , said recess 111 comprises said at least one complementary hooking means 112 as can be seen in the figure 2 , advantageously near a corner. Preferably, the main body comprises two complementary attachment means 112 located on a second axis YY' perpendicular to the first axis X-X'.

The mobile hooking device 3 is movable between a first position ensuring the hooking of the tank 2 with the main body 1 and a second position allowing a user to assemble or disassemble the tank 3 with the main body 1. In d In other words, to be able to move the tank 2 from its hooked position to its unhooked position, the user must move the mobile hooking device 3.

More precisely, to bring or maintain the tank 2 in its hooked position, it is necessary to bring or maintain the mobile hooking device 3 in its first position. The first position of the mobile attachment device 3 therefore corresponds to the attached position of the reservoir 2 and therefore to an operating position of the hairdressing appliance. In order to secure the attachment of the tank 2 and to limit user intervention, advantageously, the first position of the mobile attachment device 3 is a rest position. In other words, without action on the part of the user, the mobile hooking device 3 is naturally in its first position, that is to say in the position ensuring the hooking of the tank 2 with the main body 1 of the hairdressing appliance.

Conversely, to bring the tank 2 into its unhooked position, it is necessary to bring the mobile attachment device 3 into its second position which will cause the unhooking of the tank 2 as will be detailed later.

In the different figures, the mobile attachment device 3 is precisely represented in this second position.

Preferably, as can be seen in the different figures, the mobile hooking device 3 comprises at least one button 31, and preferably two buttons 31. By button we mean any part intended to be directly activated by the user , preferably by the hand of the user and more particularly by at least one finger of the user. Preferably, button 31 is a push button designed to be actuated by a single finger of the user. Said at least one button 31 is connected, preferably rigidly, with the hooking means 333 so that when the user activates said at least one button 31, this will cause the hooking means 333 to move, more precisely to make remove the hooking means 333 from the complementary hooking means 112 (that is to say that said hooking means 333 from the complementary hooking means 112 no longer cooperate with each other) and therefore pass the device mobile attachment 3 from its first position to its second position or vice versa. In other words, the mobile attachment device 3 can then move between said first and second positions.

Advantageously, the mobile hooking device 3 is movable in translation relative to the tank 2, that is to say that the mobile hooking device 3 moves in a translational movement, and advantageously only a translational movement, opposite reservoir 2 which then constitutes a fixed frame of reference.

Preferably, as can be seen in the figure 8 , said mobile attachment device 3 is movable in translation relative to the tank 2 along a second axis YY' perpendicular to said first axis X-X'. In other words, the translation movement of the mobile hooking device 3 then takes place perpendicular to the longitudinal direction of the tank 2. In the preferential case where the mobile hooking device 3 comprises two buttons 31, this means that the two buttons 31 are movable in translation along the second axis Y-Y'. Such a configuration presents a quite remarkable improvement in ergonomics since it is then possible for the user to manipulate the tank 2 and its hooking system, namely the mobile hooking device 3 with one hand. . More precisely, the user can position the reservoir 2 in the palm of his hand, the first axis XX' substantially perpendicular to his arm. The mobile hooking device 3 and in particular the buttons 31 then find themselves in an ideal position to be able to be directly actuated by the thumb and index finger of the user's hand holding the tank.

As can be seen on the figures 9 And 10 , the mobile attachment device 3 comprises a plane of symmetry P perpendicular to the second axis Y-Y'. In other words, the plane P can include the first axis X-X'. The mobile attachment device 3 is thus perfectly symmetrical with respect to the plane P. The mobile attachment device comprises two subassemblies distributed on either side of the plane P and symmetrical with respect to the plane P. Consequently, in the following description, only one of the subsets will be described, the other being the symmetry of the first subset, like a mirror.

The foot 33 of the mobile attachment device is integral with said button 31. Preferably, the foot 33 is in material continuity with the button 31, that is to say it is made of the same material and can be made simultaneously with the button for example by a machining or molding operation. However, the foot 33 can also be assembled with the button 31 for example by welding. The foot 33 preferably has the shape of an inverted T. The vertical bar of the T is then secured to the button 31 while the horizontal bar of the T includes the hooking means 333.

Preferably, the mobile attachment device 3 comprises a translation guide device 331 advantageously formed by the vertical bar of the T of the foot 33. The reservoir 2 then comprises a complementary translation guide device 231 visible on the Figure 7 , advantageously formed by a bar of the guide frame 23. Said translation guide device 331 and complementary translation guide device 231 then cooperate with each other so as to guide the mobile attachment device 3 in translation within the tank 2, and more precisely within the guide frame 23.

Preferably, as can be seen in the figure 8 , the translation guidance is carried out by a slide connection advantageously formed by the vertical bar of the T moving inside a U-shaped space formed by the guide frame 23 as can be seen on the figures 7 And 8 , and by the horizontal bar of the T which rests on the U, the length of the horizontal bar of the T being greater than the opening of the U. Preferably, the U formed at within the guide frame 23 is open to the outside, and the second axis YY' is an axis of symmetry for the U-shaped space of the guide frame 23. In addition, the button 31 is also designed to rely on the U of the guide frame 23. Thus, the particular shape of the mobile attachment device 3, and in particular of its foot 33, combined with the complementary shape of the guide frame 23 makes it possible to produce a slide connection to guide the translation in translation mobile attachment device 3 within the guide frame 23 of the reservoir 2 of the hairdressing appliance. One could imagine, without departing from the scope of the invention, similar translation guidance which could be produced using a dovetail type device. Preferably the slide connection has a Y-Y' axis.

Preferably, the mobile attachment device 3 comprises a first stopping device in the first position 341 as can be seen in the Figure 9 Or 10 . More precisely, the button 31 presents, in top view, the shape of a T, the horizontal bar of the T constituting the portion that the user will operate with his finger, as can be seen on the Figure 9 . The button 31 advantageously comprises a first lug 34 which projects from the vertical bar of the T that the button 31 forms, in a direction similar to that of the foot 33. Preferably, the lug 34 and the foot 33 extend in directions parallel, and advantageously in the same direction. Advantageously, the first lug 34 comprises a substantially flat surface perpendicular to the vertical bar of the T formed by the button 31, said surface forming said first stopping device in the first position 341. said first stopping device in the first position 341 is thus advantageously parallel to the plane P.

Advantageously, the button 31 has reliefs making it possible to improve the quality of contact between the button 31 and the user's finger. These reliefs also make it possible to visually indicate to the user where to position their finger to release tank 2.

Preferably, the reservoir 2 comprises a first complementary stopping device in the first position 232, as can be seen in the Figure 7 . More precisely, said first complementary device for stopping in the first position 232 is included in the guide frame 23 which forms at this location a window of substantially rectangular shape. Said first complementary device for stopping in the first position 232 is then formed by a bar parallel to the first axis X-X'. Preferably said bar is of rectangular or square section so as to offer substantially flat lateral surfaces, and in particular a lateral surface substantially parallel to the first stopping device in first position 341.

Said first stopping device in the first position 341 and first complementary stopping device in the first position 232 then cooperate with each other so as to prevent the translation of the mobile hooking device 3 beyond said first position, in other words terms, so as to provide a first position stop for the mobile hooking device 3. As can be seen on the figures 7 to 10 , the cooperation in question is advantageously a cooperation of the plan-on-plan type. This provides good contact which distributes the forces well and therefore guarantees a reliable, robust and durable stop in first position over time. This makes it possible to limit the translation movement of the mobile attachment device 3 so that the latter cannot exceed its first position. Good stopping quality is all the more important since, as explained previously, the first position can correspond to a rest position, that is to say a position very frequently occupied by the mobile attachment device 3.

Preferably, the mobile attachment device 3 comprises a second stopping device in the first position 351 visible in particular on the figures 9 And 10 . More precisely, the button 31 advantageously comprises a second lug 35 which projects from the vertical bar of the T formed by the button 31, in a direction opposite but parallel to that of the foot 33. Preferably, the first lug 34 and the second lug 35 extend in directions parallel but opposite. In other words, said first and second lug 34, 35 extend on either side of the vertical bar of the T formed by the button 31 as can be seen on the Figure 9 . Preferably, the second lug 35 is parallel to the plane P.

Preferably, the reservoir 2 comprises a second complementary device for stopping in the first position 233 visible on the Figure 7 . The latter can then be formed by a wall of a notch made directly in the upper casing 21 of the tank 2. Preferably, the second complementary device for stopping in the first position 233 extends longitudinally parallel to the first axis X-X'.

Said second stopping device in the first position 351 and second complementary stopping device in the first position 233 then cooperate with each other so as to prevent the translation of the mobile attachment device 3 beyond said first position, in other words terms, the way of providing a first position stop to the mobile attachment device 3. Here too, the cooperation is advantageously a plan-on-plan type cooperation which therefore presents the same advantages as those previously cited. The fact that the mobile attachment device comprises two first position stopping devices 341, 351 each cooperating with two complementary first position stopping devices 232, 233 of the tank 2 therefore makes it possible to offer two first position stops to the mobile hooking device 3. This makes it possible to properly distribute the contact pressures between the two stops, and therefore to improve the strength, reliability and durability of the mobile hooking device 3. In addition, each of these stops allows to keep the button 31 secured to the tank and to avoid accidental disassembly of the mobile attachment device 3 from the tank 2.

Preferably, the mobile attachment device 3 comprises a second position stopping device 332 visible on the Figure 10 and advantageously formed by the foot 33. More precisely, said second position stopping device 332 is formed by a surface of the foot 33 which is substantially parallel to the first first position stopping device 341 and preferably parallel to the plane P. Thus , said stopping device in the second position 332 and first stopping device in the first position 341 form two parallel stops which limit the translation movement of the mobile attachment device 3.

Preferably, the reservoir 2 comprises a complementary device for stopping in the second position 234, visible on the Figure 7 . The complementary device for stopping in the second position 234 is then advantageously parallel to the first complementary device for stopping in the first position 232, for example by being arranged on an opposite face of the same bar of the guide frame 23.

Said second position stopping device 332 and complementary second position stopping device 234 then cooperate with each other so as to prevent the translation of the mobile hooking device 3 beyond said second position so as to form a stop of second position, in particular when the user exerts pressure on the button(s) 31.

Preferably, as mentioned previously, the plane P forms a plane of symmetry for the mobile attachment device. Thus, the movable hooking device comprises two buttons 31, two feet 33, two first lugs 34, two second lugs, two translation guide devices 331, two second position stopping devices 332, two hooking means 333 , two first stopping devices in the first position 341, two second stopping devices in the first position 351, each of them being distributed symmetrically on either side of the plane P as can be seen on the figures 9 And 10 .

Advantageously, the mobile attachment device 3 comprises an elastic return device 32, visible on the Figure 9 , designed to maintain the mobile attachment device 3 in its first position. The elastic return device 32 is preferably a helical spring, designed to keep the buttons 31 apart. However, one could, without departing from the scope of the invention, imagine other return devices which would make it possible to keep the buttons 31 apart, c that is to say, to maintain the mobile attachment device 3 in the first position. We could for example think of an electromagnetic device, the tank 2 being equipped with a magnet and each of the buttons 31 being made of magnetic material (or vice versa). Preferentially, as illustrated by Figure 9 , the elastic return device 32 is arranged between the two buttons 31, which makes it possible to benefit from a simple construction and allowing the elastic return device 32, in this case the helical spring, to transmit all its force to the buttons 31 and only to the buttons 31. Preferably, the mobile attachment device 3 comprises a housing 312 designed to accommodate the elastic return device 32 as can be seen in the Figure 9 . This ensures that the elastic return device 32 is maintained in position and guides the latter when it deforms. The housing 312 is advantageously formed by a groove starting from one end of the button 31, in this case the free end of the vertical bar of the T that the button 31 forms and extending partly towards the inside of the button 31, preferably along the second axis Y-Y'. Thus, when the mobile hooking device 3 is in its second position, the two buttons 31 are in contact, the bulk of the mobile hooking device is zero since it is entirely integrated into the housing 312, this is that is to say inside the buttons 31. This makes it possible to limit the bulk of the mobile hooking device 3. As can be seen in the Figure 9 , the elastic return device extends longitudinally along the second axis Y-Y'.

Advantageously, as can be seen in the Figure 9 , the second axis YY' forms an axis of symmetry for the mobile attachment device 3.

As can be seen on the figure 8 , the first axis XX' forms an axis of symmetry for the guide frame 23, the plane P preferably forms a plane of symmetry for the guide frame.

Preferably, the tank 2 comprises an additional fixed attachment device 221, that is to say non-movable and non-deformable, visible on the figures 5 And 6 , and advantageously comprising a tongue, of substantially rectangular shape, projecting from the reservoir in a direction parallel to the first axis X-X'. Preferably, the additional hooking device 221 is located at one longitudinal end of the tank 2 and advantageously opposite the mobile hooking device 3, itself located at another longitudinal end of the tank 2. This makes it possible to distance to the maximum the different attachment points of the tank 2 on the main body 1 which improves the stability and mechanical resistance of the attachment of the tank 2 relative to the main body 1. In addition, in the preferred case illustrated where the device mobile attachment 3 comprises two attachment means 333, this gives the tank 2 three attachment points on the main body 1, which corresponds to an isostatic assembly. In addition, the attachment points can remarkably be arranged in a triangle thanks to the arrangement of two attachment means 333 on the second axis YY' and the arrangement of the additional attachment device 221 on an axis parallel to the first axis -X', or possibly on the first axis X-X'. An arrangement of the attachment points of the tank 2 on the main body 1 in the shape of a triangle makes it possible to improve the stability and mechanical resistance of the connection between the tank 2 and the main body 1, and therefore the reliability of the hooking between the two elements.

The main body 1 then comprises an additional complementary hooking means 113 visible on the figure 2 . The complementary additional hooking means 113 comprises for example a groove of substantially rectangular shape made inside the main body 1 from the recess 111 in a direction parallel to the first axis X-X'.

Said additional hooking device 221 and complementary additional hooking means 113 are then designed to cooperate together when the tank 2 is in the hooked position, the additional hooking device 221 being preferably a male hooking device and the means of the complementary additional hooking 113 being preferably a complementary female hooking means. The illustrated embodiment uses at least one additional complementary hooking means 113 cooperating with at least one additional hooking device 221, but one could quite imagine the multiplication of these elements in order to reinforce the mechanical resistance of the hooking .

As shown in the figures 5 And 6 , the tank 2 comprises at least one guide device 24 designed to cooperate with at least the complementary guide device 114 of the main body 1 when the tank is in the hooked position. This makes it possible to provide at least one guide means between the hooking means 333 and the additional hooking device 221, which greatly facilitates the operation of hooking the tank 2 to the main body by offering the user guidance. intermediate. In addition, the guide devices 24 and complementary guide device 114 make it possible to reinforce the mechanical resistance of the attachment once the tank 2 is in the attached position, by blocking any translational movement of the reservoir 2 along the first axis X-X'. This makes it possible to relieve the attachment means 333 and the additional attachment device 221 which then only have to ensure anti-tearing attachment, along a third axis perpendicular to the first axis X-X'. The strength and durability of the tank is thus improved. The greater the length of tank 2, the greater the presence of this intermediate guide point. Preferably the guide device 24 is a female guide device, such as for example a hole or, as illustrated, a side notch in the shape of a half hole. The complementary guide device 114 is then a complementary male guide device which can take the form of a half (in a longitudinal direction) circular pin as can be seen in the figure 2 . Advantageously, the tank 2 comprises two guide devices 24 and the main body 1 comprises two complementary guide devices 114.
