Description

[Technical field]

[0001] The present invention relates to the field of hair styling devices, preferentially those that vaporize a liquid and diffuse it towards the hair, such as for example steam styling devices.

[0002] More specifically, the present invention relates to the field of hair styling devices, comprising a vaporizer designed to vaporize a liquid and disperse it towards the hair, a main body and a removable tank intended to contain the liquid to be vaporized and assembled to the main body in order to connect to the vaporizer and supply the liquid to be vaporized to the vaporizer.

[0003] The present invention also relates to the field of tanks for hair styling devices, more specifically tanks intended to contain the liquid to be vaporized and to be assembled in the body of the hair styling device, the tank being intended to be connected to a vaporizer of the hair styling device designed to vaporize the liquid and diffuse it towards the hair. [Background technology]

[0004] There are many hair styling devices that are used to vaporize a liquid and diffuse it towards the hair. Indeed, vaporizing a liquid onto the hair during styling is known to improve the effectiveness and results of the hair styling operation.

[0005] To carry out this vaporization, known hair styling devices are equipped with a tank for containing the liquid to be vaporized. This tank is usually removable from the body of the hair styling device to facilitate filling. Thus, the user must frequently, generally at least once before each hair styling operation, remove the tank from the body of the device, fill it with liquid (e.g. water), and then assemble the tank to the body of the hair styling device in order to supply the liquid to be vaporized to the hair styling device.

[0006] On the whole, users are satisfied with these hair styling devices, especially with regard to the styling results obtained. On the other hand, certain disadvantages or risks nevertheless exist when handling these devices, especially when assembling the tank to the device body or when removing it from the device body.

[0007] Indeed, if the tank is not correctly assembled to the device body, liquid may leak during the hair styling operation. These risks are greatly increased by the fact that the hair styling device in question is designed to be operated manually by the user and to undergo a large number of movements in connection with the hair styling operation. Furthermore, the tank may accidentally detach from the hair styling device. As the hair styling device in question is usually an electrical appliance, these leaks or this detachment may cause inconvenience to the user, ranging from simply wetting his / her clothes to the risk of, for example, electrocution.

[0008] In order to limit this type of risk, various principles have been proposed for attaching the reservoir to the body of the hair styling device.

[0009] For example, as found in many commercially available devices and as shown in the patent application WO 2005 / 023363, one known solution consists in sliding the tank into the body of the hair styling device to assemble it, which then has to be slid in the body in order to be assembled or detached. The tank is then partly held in place by friction depending on the sliding direction. However, this solution is particularly inconvenient for the user, who, when he / she wants to assemble the tank to his / her hair styling device and detach it from the hair styling device, has to grip the body of the hair styling device with one hand and firmly grip the tank with the other hand, and then exert a substantial relative movement between those parts in order to detach or assemble them. This operation therefore requires both the user's hands as well as a considerable effort, both in terms of amplitude and force (to overcome the frictional forces). Also, with repeated assembly and detachment operations, the parts that rub against each other wear and become loose, and the reliability of the assembly decreases over time, which could then lead to accidental detachment.

[0010] Another known solution is to equip the body of the device with an element whose elastic deformation ensures the assembly or removal of the tank. The elasticity of this element, usually a tab, thus not only ensures that the tank is held in the latched position, but also allows the user to elastically deform this tab during the assembly or removal operation by applying a force to the tank. This solution proves to be particularly unreliable in terms of holding the tank in place and offers the risk of accidental removal. Moreover, this solution is not very durable in the long term, since due to repeated assembly and removal operations the tab will wear and the assembly will come loose, which will increase the risk of accidental removal. Also, there is a high risk of fatigue failure of the tab after it has been repeatedly deformed, and the tank may no longer be held in the body. The reliability and durability of this solution therefore appears to be limited.

[0011] Thus, there is a need to improve upon existing devices, particularly with regard to the assembly of the tank with the body of the device. [Prior art documents] [Patent documents]

[0012] [Patent Document 1] International Publication No. 2017 / 008413 Summary of the Invention [Problem to be solved by the invention]

[0013] The present invention aims to remedy the aforementioned drawbacks.

[0014] One of the objects of the present invention is to provide a particularly reliable and robust reservoir for a hair styling device.

[0015] One object of the present invention is to provide a particularly durable reservoir for a hair styling device.

[0016] One object of the invention is to provide a reservoir for a hair styling device which is particularly easy to handle, in particular when assembling the reservoir to the hair styling device or when removing the reservoir from the hair styling device.

[0017] One of the objects of the present invention is to provide a reservoir for a hair styling device that is particularly intuitive and ergonomic to handle, in particular when assembling the reservoir to the hair styling device or when removing the reservoir from the hair styling device.

[0018] One of the objects of the present invention is to provide a reservoir for a hair styling device which is particularly compact and lightweight.

[0019] One of the aims of the present invention is to provide a hair styling device which is particularly reliable and robust.

[0020] One of the aims of the present invention is to provide a hair styling device which is particularly durable.

[0021] One of the objects of the invention is to provide a hair styling device that is particularly easy to handle, in particular when assembling the tank to the body of the hair styling device or when removing the tank from the hair styling device.

[0022] One of the objects of the present invention is to provide a hair styling device that is particularly intuitive and ergonomic to handle, especially when assembling the tank to the body of the hair styling device or when removing the tank from the hair styling device.

[0023] One of the aims of the present invention is, inter alia, to provide a hair styling device which is compact and lightweight. [Means for solving the problem]

[0024] These objects are achieved by a tank intended to contain a liquid to be vaporized and assembled to the body of the hair styling device, the tank being intended to be connected to a vaporizer of the hair styling device designed to vaporize the liquid and to diffuse it towards the hair, the tank having a movable latching device including at least one latching means designed to correspond to at least one complementary latching means belonging to the body, for latching the tank to the body, the movable latching device being movable between a first position providing latching between the tank and the body and a second position allowing the user to assemble the tank to the body or to remove the tank from the body.

[0025] These objects are also achieved by a hair styling device comprising a vaporizer designed to vaporize a liquid and to diffuse it towards the hair, a main body and a removable tank intended to contain the liquid to be vaporized and intended to be assembled to the main body in order to be connected to the vaporizer and to supply the liquid to be vaporized to the vaporizer, the tank being characterized in accordance with the above description.

[0026] The invention therefore relates to two separate products, in this case a tank for a hair styling device and a hair styling device, whereby there is a connection between them, since the tank is designed to be connected to the hair styling device.

[0027] Preferentially, the liquid is water. However, the invention is not limited to this particular liquid, and the liquid may be, for example, an oil, a cosmetic product, or any other liquid product that may be spread on the hair to treat the hair or to improve the effectiveness of a hair styling operation. The liquid may optionally be a mixture of water and another product, such as, for example, a cosmetic product.

[0028] In this case, the expression "vaporize" can be understood in the broadest sense. It therefore refers to the ejection of any type of liquid, regardless of its nature, form or state. Thus, for example, a liquid may be evaporated by being dispersed as a multitude of fine droplets, preferentially of microscopic size, e.g., as a mist.

[0029] Preferentially, "vaporize" can also be understood in its strict physical sense, ie as an operation which results in a liquid being converted into a vapor. In other words, "vaporization" can mean a change of state, where a liquid changes from a liquid state to a gaseous state. For example, in the preferential case where the liquid is water, this change of state, i.e., this vaporization, occurs when the liquid reaches a temperature of 100° C. under normal atmospheric pressure.

[0030] "Tank" refers to any type of watertight container capable of holding a liquid, preferentially water. Preferentially, the tank volume is between 5 mL and 500 mL, advantageously between 15 mL and 100 mL. Preferentially, the tank is made of plastic. Advantageously, the tank comprises an upper housing and a lower housing, which are assembled such that they cannot be separated (for example by joining or welding).

[0031] The reservoir is removable, which means that it can be assembled to and detached from (or hooked and removed from) the body of the hair styling device as required without deterioration of the reservoir or the body.

[0032] In particular, the reservoir may be in a latched position, in which it is attached to the body of the hair styling device and in which it is coupled to, and advantageously sealed to, the body, said latched position enabling the reservoir to deliver the liquid it contains to the hair styling device, so that the vaporizer can vaporize the liquid and then diffuse it towards the hair.

[0033] The tank may also be in an unlatched position, in which it is not coupled to the body. Preferentially, the tank is separated from the body and can then be freely and easily handled by the user, for example to fill it, clean it, etc.

[0034] "Mobile hanging device" is understood to mean, preferentially, any mobile device or means, i.e. which can be moved to several positions and which, inter alia, allows the tank to be hung (i.e. attached) to or on the body of the hair styling device. For this purpose, the mobile hanging device of the invention comprises at least one hanging means designed to correspond to at least one complementary hanging means belonging to the body, in order to hang the tank to the body. Thus, two hanging means are used which are complementary between them: on the one hand a hanging means integrated into the mobile hanging device, preferentially a male hanging means, and on the other hand a complementary hanging means integrated into the body of the hair styling device, preferentially a complementary female hanging means. And the at least one hanging means of the mobile hanging device and the at least one complementary hanging means of the body cooperate with each other to ensure the hanging, i.e. the attachment between the tank and the body. Preferentially, the movable latching device comprises two latching means designed to correspond to two complementary latching means belonging to the body in order to attach the tank to the body at two separate points, which enhances the mechanical strength of the latching.

[0035] The latching device of the present invention is movable between a first position, which ensures that the tank is latched to the body, and a second position, which allows the user to assemble the tank to the body or to remove the tank from the body. In other words, the first position of the movable latching device corresponds to the latched position of the tank as defined above. The second position of the movable latching device corresponds to the unlatched position of the tank as defined above. Thus, the movable latching device of the present invention allows the user to easily and quickly control the movement of the tank from its latched position to its unlatched position or vice versa. Also, since the movable latching device is incorporated on the tank, it allows it to be operated with the same hand that grips the tank. The movable latching device allows the tank to be moved from its latched position to its unlatched position according to the user's desire. Thus, the user can latch or unlatch the tank with one hand. In particular, only a deliberate action by the user on the movable latching device (the user has to move it between two positions) allows the reservoir to be moved from its latched position to its unlocked position, which avoids accidental removal of the reservoir from the body of the hair styling device, which significantly enhances the user comfort and safety of the hair styling device.

[0036] A "hair styling device" is any type of device that allows a user to perform a styling operation on hair (or optionally, for example, on the fur in the case of an animal). For example, a hair styling device can be a straightening iron for straightening hair, a hair iron for creating curls or waves, or a multi-purpose device for creating various types of hairstyles.

[0037] According to one embodiment, the hair styling device comprises a first arm connected by a hinge to a second arm so as to form a movable clip between an open position and a closed position. The open position allows the user to insert the hair into the device, and the closed position allows the user to apply pressure and preferentially heat the hair to shape it, usually to straighten it. The device thus forms a hair straightening iron, which is a device well known per se and will not be further detailed here. In particular, this type of device comprises in particular at least one, preferentially two, heat treatment surfaces arranged at the end of the arm (or each arm) and designed to contact the hair and transfer heat thereto.

[0038] "Body" refers preferentially to the part of the hair styling device designed to house the tank. According to one embodiment, the body comprises the vaporizer and advantageously the first and second arms. However, embodiments could be conceived in which the hair styling device comprises a body containing a removable tank and a second body, in particular comprising the vaporizer and advantageously the first and second arms. In this case, the body and the second body would be connected to each other by a cord designed to convey the liquid contained in the main tank to the second body.

[0039] Advantageously, the body comprises a recess that is complementary in shape to at least part of the shape of the reservoir and designed to accommodate at least part of the reservoir when the reservoir is in the latched position, the recess comprising at least one complementary latching means. The reservoir is thus at least partially arranged inside the body of the hair styling device, which on the one hand makes it possible to limit the overall footprint of the hair styling device and on the other hand ensures that the reservoir is firmly maintained in its latched position.

[0040] According to a preferential embodiment, the movable hanging device comprises at least one button intended to be directly actuated by the user in order to move the movable hanging device from its first position to its second position or vice versa. This makes the movable hanging device, and thus the hair styling device, particularly simple and intuitive to use. Advantageously, the button is a push button designed to be actuated by one finger of the user's hand. Preferentially, the movable hanging device comprises two buttons, which makes it possible to distribute the effort and thus improve the ergonomics of the tank and the hair styling device. Advantageously, the two buttons are coaxial and oriented in opposite directions, so that they can be actuated by the user using a pinching action between two fingers, for example between the thumb and index finger. In fact, this is a natural and intuitive movement for humans when handling objects.

[0041] According to one advantageous embodiment, the mobile latching device is translatable relative to the tank, in other words, a movement of the mobile latching device causes it to move relative to the tank, which will leave the tank stationary. This mode of movement of the movable latching device makes it possible to reconcile simplicity, robustness and ergonomics.Indeed, this embodiment allows the user to place the tank in the palm of his / her hand while translatingly actuating the movable latching device with one or more fingers of this hand.

[0042] Preferentially, the tank extends longitudinally along a first axis and the mobile latching device is translationally movable relative to the tank along a second axis perpendicular to the first axis. Having a translational movement perpendicular to the tank's longitudinal axis makes it possible to obtain a particularly ergonomic tank insofar as a minimum of effort is required to hold the tank with one hand. In fact, the tank's longitudinal axis is located in the palm of the hand, giving the tank an excellent support, and therefore the translational movement of the mobile latching device perpendicular to the longitudinal axis is significantly better oriented with respect to the movements of the thumb and / or index finger of the hand holding the tank.

[0043] According to this advantageous embodiment, the mobile latch device comprises a translational guide device and the tank comprises a complementary translational guide device, which translational guide device and the complementary translational guide device cooperate with each other to translationally guide the mobile latch device in the tank. The translational movement of the mobile latch device is thus limited to a single translational movement guided by the tank itself. This ensures easy movements, good ergonomics and intuitiveness for the user, so that the user cannot mishandle it.

[0044] Also according to this advantageous embodiment, the mobile latching device preferentially comprises a first stop device in the first position and the tank comprises a first complementary stop device in the first position, the first stop device in the first position and the first complementary stop device in the first position cooperating with each other in such a way as to prevent the translation of the mobile latching device beyond the first position. The translational movement of the mobile latching device is therefore limited by the tank itself so as not to exceed the first position. This ensures easy movements, good ergonomics and intuitiveness for the user, so that the user cannot mishandle. Also advantageously, the mobile latching device comprises a second stop device in the first position and the tank comprises a second complementary stop device in the first position, the second stop device in the first position and the second complementary stop device in the first position cooperating with each other in such a way as to prevent the translation of the mobile latching device beyond the first position. The translational movement of the mobile latching device is therefore doubly limited by the tank itself. This ensures, at the two restraints, good mechanical strength and in particular eliminates the risk of accidental removal of the mobile latching device from the tank.

[0045] Also according to this advantageous embodiment, the mobile latching device preferentially comprises a stop device in the second position and the tank comprises a complementary stop device in the second position, the stop device in the second position and the complementary stop device in the second position cooperating with each other in such a way as to prevent translation of the mobile latching device beyond the second position. The translational movement of the mobile latching device is thus limited by the tank itself not to exceed the second position. This ensures easy movement, good ergonomics and intuitiveness for the user, so that the user cannot mishandle it. Finally, when the above two preferential structures are combined in this advantageous embodiment, the movement of the mobile latching device is completely limited by and within the tank for translational movement between the first and second positions. This ensures easy movement, good ergonomics and intuitiveness for the user, so that the user cannot mishandle it.

[0046] According to one embodiment, the first position of the movable latching device is a rest position. In other words, the movable latching device is naturally or by default held stably in its first position, i.e. in a position that ensures that the reservoir is latched to the body of the hair styling device. This substantially improves the safe use of the device, since without any manipulation by the user, the reservoir remains firmly attached to the body of the hair styling device. For this purpose, the movable latching device preferentially comprises a resilient return device, which is preferentially a coil spring, which ensures reliability, robustness and low manufacturing costs. However, any other suitable means of making the first position a rest position may be considered, such as, for example, a ferromagnetic device. In the preferential case in which the movable latching device comprises two buttons, the resilient return device is advantageously arranged between the two buttons in order to press or release the buttons. This makes it possible to realize a simple, inexpensive, reliable and very effective construction from a mechanical point of view. Preferentially, the movable latching device comprises a housing designed to accommodate the resilient return device. This housing therefore makes it possible, on the one hand, to limit the footprint of the movable latching device by incorporating the elastic return device, and, on the other hand, to ensure the guidance and retention of the elastic return device during movement, which will improve the overall reliability. Advantageously, when the movable latching device is in the second position, the two buttons come into contact, which makes it possible to form another stop in the second position to withstand the efforts exerted on the buttons by the user. This enhances the mechanical strength of the movable latching device and the reliability of the tank.

[0047] According to one embodiment, the tank comprises an additional fixed latching device designed to cooperate with an additional complementary latching means belonging to the body when the tank is in the latched position. Thus, two other complementary latching means can be used to improve the latching of the tank to the body of the hair styling device: on the one hand, an additional fixed latching device, i.e. a non-movable and non-deformable, male latching device, preferentially integrated in the tank, and on the other hand, an additional complementary latching means, preferentially a complementary female latching means, integrated in the body of the hair styling device. The additional fixed latching device and the additional complementary latching means then cooperate with each other to ensure the latching, i.e. the attachment between the tank and the body. Preferentially, the additional fixed latching device and the additional complementary latching means are arranged parallel to the longitudinal axis of the tank, while at least one latching means and the complementary latching means are arranged perpendicular to the longitudinal axis of the tank. This allows for a proper distribution of the fastening points of the tank and the body and therefore improves the mechanical strength of the fastening.

[0048] According to one embodiment, the reservoir comprises at least one guiding device designed to cooperate with at least one complementary guiding device of the body when the reservoir is in the latched position. In other words, two complementary guiding devices are used to improve the latching of the reservoir on the body of the hair styling device as well as to facilitate the assembly and removal of the reservoir by guiding the movement of the reservoir, with, on the one hand, a guiding device, preferentially of the female type, integrated in the reservoir, and, on the other hand, a complementary guiding device, preferentially of the male type, integrated in the body and preferentially integrated in a recess.

[0050] The embodiment of the invention shown in the various figures is one in which the hair styling device that is the subject of the invention is a steam hair straightening iron. The tank 2, and therefore the subject of the invention, is a tank for a steam hair straightening iron. However, other embodiments are entirely conceivable without departing from the scope of the invention, such as, for example, a steam hair iron.

[0051] As can be seen in FIG. 1, the hair styling device comprises a first arm 11 connected to a second arm 12 by a hinge 13 so as to form a clip that can be moved between an open position and a closed position. The first and second arms 11, 12 are gripping means for the user's hands. For this purpose, they form a handle that preferentially forms a gripping area over at least a part of their length. The hair styling device is shown in the closed position in FIG. 1. The hinge 13 is thus substantially arranged at the ends of the first and second arms 11, 12. The structure and operation of this type of hair styling device are well known per se and therefore they will not be described in further detail here. For example, it is known that each of said first and second arms 11, 12 comprises a heat treatment surface intended to come into contact with the hair. These treatment surfaces are arranged at the respective ends of the first and second arms 11, 12, on opposite sides of the hinge 13. The hinge 13 is typically a shaft around which the first and second arms are attached.

[0052] As shown in Figures 1 and 2, the hair styling device comprises a body 1 designed to house a tank 2, as will be described in detail below. In other words, the tank 2 is intended to be assembled to the body 1. According to the illustrated embodiment, the body 1 comprises a first and a second arm 11, 12. It is also possible to envisage an alternative embodiment in which the hair styling device would comprise a second body, separate from the body 1, housing the tank 2. The second body would then comprise the first and second arms 11, 12, as well as the hinge 13. The body 1 and the second body would then be connected to each other by a cord for conveying liquid from the tank 2 of the body 1 to the second body, more specifically, for example, to the first arm 11.

[0053] 2, the body 1 advantageously includes a recess 111, i.e. a hollow space within the body 1, the shape of which is complementary to at least a part of the shape of the tank 2. In other words, the recess 111 forms a hollow recess for at least a part of the tank 2. The recess 111 is thus designed to accommodate at least a part of the tank 2 when the tank 2 is in a latched position, as will be described in more detail below.

[0054] Preferentially, the body 1, and more particularly the recess 111, comprises at least one, and advantageously two, complementary guiding devices 114, as shown in Figure 2, and the at least one complementary guiding device 114 may be in the form of a circular half pin.

[0055] The hair styling device comprises a tank 2 intended to contain the liquid to be vaporized, preferentially water. The tank 2 is removable, i.e. it is possible to remove and detach the tank 2 from the hair styling device, as can be seen in figure 2, which shows the body 1 of the hair styling device when the tank 2 is removed. The tank 2 is therefore intended to be assembled to the body 1 of the hair styling device.

[0056] The tank 2 can be in a latched position, as seen in FIG. 1, in which the tank 2 is incorporated into the body 1 of the hair styling device by being precisely located at least partially in the recess 111. This makes it possible to provide a particularly compact hair styling device in which the tank is incorporated into the first arm 11. The latched position of the tank 2 corresponds to the operating position of the hair styling device. The tank 2 can also be in an unlatched position, as seen in FIGS. 2 to 8, in which the tank 2 is separated and independent from the body 1 of the hair styling device. And when the tank 2 is in the unlatched position, it is possible for the user to fill it, in particular after removing the filling cap 26, as seen in FIGS. 5 and 6. More specifically, as seen in FIG. 4, the filling cap 26 comprises a filling orifice cap 261 intended to provide a watertight seal for the filling orifice of the tank 2, and a vent orifice cap 262 intended to provide an airtight seal for the vent orifice of the tank while the tank is being filled. In fact, to make the filling operation easier, or more precisely to ensure that the atmospheric pressure of the tank 2 is maintained during filling, the tank 2 is equipped with two orifices, one with a large diameter intended to receive the liquid, and another with a smaller diameter intended to ensure ventilation even if the filling orifice is completely blocked by the liquid or by a funnel or other filling pipette.

[0057] Advantageously, as seen in FIG. 3, the tank 2 extends longitudinally along a first axis XX', i.e. the tank 2 has an overall elongated shape, such as a substantially rectangular shape, with rounded corners. In fact, this longitudinal shape is particularly adapted to allow the tank 2 to be inserted into the body 1, and more particularly into the first arm 11, as shown in FIG. 1, while maximizing the capacity of the tank 2. Preferentially, the first arm 11 extends parallel to the first axis XX'. Advantageously, the first arm 11 extends along the first axis XX'. And in this advantageous case, as shown, the tank 2 may extend more than half the length of the first arm 11, which allows maximizing the capacity of the tank 2. And the tank 2 is completely integrated into the first arm, thus constituting a grip area for the user's hand.

[0058] The tank 2 also comprises a connection device 25, preferentially seen in FIG. 5, which is intended to correspond to a complementary connection device 15, seen in FIG. 2 and arranged in the body 1, more particularly in the recess 111. As seen in these figures, the connection device 25 is a male connection device, in this case a part of a tube protruding from the tank 2, and the complementary connection device 15 is a female connection device, in this case an orifice. When the tank 2 is in its latched position, the connection device 25 and the complementary connection device 15 cooperate in a watertight manner to allow the liquid contained in the tank 2 to be supplied to the body 1 of the device, more particularly to the vaporizer device, which will be explained in more detail below. Preferentially, the connection device 25 is arranged at a longitudinal end of the tank 2, as seen in FIG. 5, and extends longitudinally parallel to the first axis XX'.

[0059] As can be seen in FIG. 4, the tank 2 comprises a suction tube 251, advantageously connected in a sealed manner to the connection device 25. The suction tube 251 extends freely inside the tank 2 and comprises at its free end a suction end 252, the mass of which is greater than the mass of the suction tube 251. This allows the suction tube 251 to be moved by gravity when the liquid itself is moved by gravity during the movement of the hair styling device. This ensures good suction of the liquid in the tank 2, regardless of its filling level or spatial position. The suction tube 251 moves freely in the tank 2, i.e. it is flexible and can move around in the tank 2. Combined with the weighted suction end 252, this solves the problem of some currently available tanks that do not allow all of the liquid to be sucked in, in other words that they cannot be emptied, for example because the amount of water is half and suction is no longer possible. This would result in a lack of autonomy of the device with the tank.

[0060] The tank 2 also comprises a venting device 27, preferentially seen in figures 4 to 6, designed on the one hand to prevent the liquid from escaping from the tank 2 and on the other hand to keep the tank 2 at atmospheric pressure. This venting device 27 makes it possible to solve the following technical problem: When the liquid is sucked out by the suction tube 251, the amount of liquid in the tank 2 decreases. However, since the tank 2 is airtight, the amount of sucked out liquid cannot be replaced by air. This leads to the development of a negative pressure in the tank 2 when the liquid is sucked out. After a certain time, the reduced pressure becomes so great that the liquid can no longer be sucked out. It is then not possible to suck out all of the liquid contained in the tank 2, which limits the autonomy of the hair styling device equipped with the tank.

[0061] The vent 27 makes it possible to counter this phenomenon by allowing air to pass into the tank 2 as the amount of liquid in the tank 2 decreases, while at the same time preventing liquid from leaking out of the tank 2.

[0062] As seen in Fig. 4, the venting device 27 includes an umbrella or mushroom shaped valve. This device may keep the valve depressed by the weight of the liquid pushing against the valve cap or head, thus preventing liquid from leaking out of the tank 2. Meanwhile, when the pressure in the tank 2 drops, the outside atmospheric pressure pushes against the foot of the valve, despite the weight of the liquid, which allows air to be pumped into the tank 2. When the pressure inside the tank 2 balances with the outside pressure (atmospheric pressure), the valve will return to its initial position by the weight of the liquid, as explained before.

[0063] As can be seen in figures 3 and 4, the tank 2 comprises an upper housing 21 and a lower housing 22 which are firmly, advantageously deterministically joined together by gluing or welding, meaning that they cannot be separated. Such an assembly makes it possible to solve the problem of assembling the tank 2 by making it much easier, or even easier, to install the various components in the tank, and in particular to install the above-mentioned suction tube 251.

[0064] As can be seen, the above described devices, in particular the suction tube 251 and the ventilation device 27, each make it possible to solve a particular technical problem and in this respect may constitute an invention in their own right.

[0065] As can be seen in figure 5 and in more detail in figure 7, the tank 2 advantageously comprises a guide frame 23, which itself preferentially comprises different bars making it possible to provide various guiding and hooking functions, as will be explained in more detail below. The guide frame 23 is advantageously arranged at a longitudinal end of the tank 2, preferentially opposite the connection device 25.

[0066] The hair styling device comprises a vaporizer designed to vaporize a liquid and diffuse it towards the hair. The vaporizer may for example comprise a vaporization chamber in which the liquid contained in the tank 2 is converted into steam when heated. The steam is then diffused towards the hair, for example through a diffusion orifice. This type of system is well known per se and will therefore not be described in detail here. Another vaporizer may for example be an atomization system that converts the liquid into fine droplets, such as a mist, without changing the state of the liquid.

[0067] The tank 2 is therefore intended to be connected to a vaporizer of the hair styling device, designed to vaporize the liquid and to diffuse it towards the hair. The tank 2 therefore supplies the vaporizer with the liquid to be vaporized. Preferentially, the connection is airtight, in particular by means of a connection device 25 and a complementary connection device 15. The hair styling device, and more preferentially the body 1, may also comprise a flow generating device, such as for example a pump and, preferentially, a peristaltic pump, making it possible to aspirate the liquid contained in the tank, using a suction tube 251, in order to convey the liquid to the vaporizer.

[0068] According to the invention, the tank 2 comprises a movable hanging device 3, as can be seen in figures 1, 3, 4, 6 and 8. In other words, the movable hanging device 3 is installed on the tank 2, i.e. the movable hanging device 3 is integrated into the tank 2. This allows a more ergonomic use of the tank 2, and thus of the hair styling device, insofar as it allows the tank 2 and the movable hanging device 3 to be handled simultaneously with one hand.

[0069] As can be seen in Fig. 10, the mobile latching device 3 comprises at least one latching means 333. More specifically, the mobile latching device 3 preferentially comprises a foot 33, itself comprising a latching part forming a rib that projects from the foot 33 and is intended to be latched on a complementary part, the rib thus forming the latching means 333. In other words, the latching means 333 is a male type latching means, whose shape is substantially rectangular. Advantageously, as shown, the mobile latching device 3 comprises two latching means 333, which makes it possible to increase the number of latching points between the tank 2 and the body 1 and thus to strengthen the mechanical strength of the latch. As can be seen in Fig. 10, the two latching means 333 are advantageously symmetrical with respect to a median plane P perpendicular to the first axis XX' of the tank.

[0070] Said at least one fastening means 333 is designed to enable the tank 2 to be latched to the body 1, i.e. to maintain the tank 2 in a latched position. Preferentially, the fastening means 333 is rigid, i.e. it cannot be deformed. This property ensures the mechanical strength of the latch between the tank 2 and the body 1, thus avoiding any risk of accidental unlatching. Moreover, unlike currently known tank latching techniques, which operate on the basis of elastic deformation of such a latching device, the rigidity of the fastening means 333 of the present invention makes it possible to guarantee the mechanical strength of the latch over time, i.e. including after multiple uses. In fact, the risk of fatigue failure of the fastening means 333 is eliminated. The reliability and lifespan of the fastening means 333, and thus of the tank 2 and thus of the hair styling device, are increased accordingly.

[0071] As can be seen in FIG. 2, the body 1, more particularly the recess 111, comprises at least one complementary fastening means 112. The complementary fastening means 112 is designed to be complementary to the fastening means 333, i.e. to cooperate with the fastening means 333 in order to ensure the fastening of the tank 2. As can be seen in FIG. 2, the complementary fastening means 112 is preferentially a female fastening means, for example comprising a substantially rectangular cavity. This complementary fastening means 112 will then receive the male fastening means 333 in order to ensure the fastening. The preferentially substantially rectangular shape of the fastening means 333 and of the complementary fastening means 112 allows to distribute the mechanical forces over a certain length, which improves the mechanical strength of the fastening of the tank 2 to the body 1, in particular with regard to withdrawal. Thus, the at least one fastening means 333 is designed to correspond to the at least one complementary fastening means 112 belonging to the body 1 in order to fasten the tank 2 to the body 1. Preferentially, as can be seen in Figure 2, the recess 111 comprises at least one complementary latching means 112, advantageously near a corner. Preferentially, the body comprises two additional complementary latching means 112 arranged along a second axis Y-Y' perpendicular to the first axis X-X'.

[0072] The movable latching device 3 is movable between a first position, which ensures that the tank 2 is latched to the body 1, and a second position, which allows a user to assemble the tank 2 with the body 1 or to remove the tank 2 from the body 1. In other words, to move the tank 2 from its latched position to its unlatched position, the user must move the movable latching device 3.

[0073] More specifically, in order to move or maintain the tank 2 in its hanging position, the movable hanging device 3 must be moved or maintained in its first position. The first position of the movable hanging device 3 thus corresponds to the hanging position of the tank 2 and thus to the working position of the hair styling device. In order to secure the hanging of the tank 2 and to limit the user's intervention, the first position of the movable hanging device 3 is advantageously a rest position. In other words, without any operation by the user, the movable hanging device 3 is naturally in its first position, i.e. the position that ensures the hanging of the tank 2 with the body 1 of the hair styling device.

[0074] Conversely, to move the tank 2 to its unlocked position, the movable latching device 3 must be moved to its second position, which will unlock the tank 2, as will be described in more detail below.

[0075] In the various figures, the movable latching device 3 is indeed shown in this second position.

[0076] As can be seen in the different figures, preferentially the movable latching device 3 comprises at least one button 31, and preferentially two buttons 31. By "button" is meant any part intended to be directly operated by a user, preferentially by the user's hand and more preferentially by at least one of the user's fingers. Preferentially, the button 31 is a push button designed to be activated by only one of the user's fingers. The at least one button 31 is preferentially rigidly connected with the latching means 333, and when the user activates the at least one button 31, this will result in the latching means 333 moving, more specifically, it will disengage the latching means 333 from the complementary latching means 112 (i.e. the latching means 333 and the complementary latching means 112 will no longer cooperate with each other) and thus move the movable latching device 3 from its first position to its second position or vice versa. In other words, the movable latching device 3 can thus be moved between a first position and a second position.

[0077] Advantageously, the movable latching device 3 is translationally movable relative to the tank 2, i.e. it moves translationally, advantageously only translationally, relative to the tank 2, and this constitutes a fixed reference coordinate system.

[0078] Preferentially, as can be seen in FIG. 8, the mobile latching device 3 is translationally movable relative to the tank 2 along a second axis YY′ perpendicular to the first axis XX′. In other words, the translational movement of the mobile latching device 3 thus occurs perpendicular to the longitudinal direction of the tank 2. In the preferential case in which the mobile latching device 3 comprises two buttons 31, this means that the two buttons 31 are translationally movable along the second YY′ axis. Such an arrangement is thus a completely notable ergonomic improvement, since it is possible for the user to handle the tank 2 and its latching system, i.e. the mobile latching device 3, with one hand. More specifically, the user may place the tank 2 on the palm of his / her hand, with the first axis XX′ substantially perpendicular to his / her arm. The mobile latching device 3, and in particular the button 31, is then in an ideal position to be directly actuated by the thumb and index finger of the user's hand holding the tank.

[0079] As can be seen in Figures 9 and 10, the movable latch device 3 includes a plane of symmetry P perpendicular to the second YY' axis. In other words, the plane P may include the first axis XX'. Thus, the movable latch device 3 is completely symmetrical with respect to the plane P. The movable latch device includes two subassemblies arranged on either side of the plane P and symmetrically arranged with respect to the plane P. Thus, in the following description, only one of the subassemblies will be described, the other one being a mirror image of the first subassembly.

[0080] The foot 33 of the movable latching device is fixed to the button 31. Preferentially, the foot 33 is materially continuous with the button 31, which means that the foot 33 is made of the same material as the button and can be made at the same time, for example by machining or integral molding. However, the foot 33 can also be assembled with the button 31, for example by welding. The foot 33 is approximately in the shape of an inverted T. The vertical bar of the T is thus connected to the button 31, while the horizontal bar of the T comprises the latching means 333.

[0081] Preferentially, the mobile latching device 3 comprises a translational guide 331, advantageously formed by a vertical bar of the T-shape of the foot 33. The tank 2 therefore comprises a complementary translational guide 231, advantageously formed by a bar of the guide frame 23, as can be seen in figure 7. The translational guide 331 and the complementary translational guide 231 therefore cooperate with each other to translationally guide the mobile latching device 3 in the tank 2, and more particularly in the guide frame 23.

[0082] Preferentially, as seen in FIG. 8, the translational guidance is performed by a sliding link, advantageously formed by a vertical bar of a T-shape moving in the U-shaped space formed by the guide frame 23, as seen in FIGS. 7 and 8, and a horizontal bar of the T-shape on the U-shape, the length of the horizontal bar of the T-shape being longer than the opening of the U-shape. Preferentially, the U-shape formed in the guide frame 23 opens outwards, the second YY′ axis being the symmetry axis of the U-shape space of the guide frame 23. Furthermore, the button 31 is also designed to push against the U-shape of the guide frame 23. Thus, the particular shape of the movable hanging device 3, in particular its foot 33, combined with the complementary shape of the guide frame 23, makes it possible to generate a sliding link for guiding the movable hanging device 3 in the guide frame 23 of the tank 2 of the hair styling device. Similar translational guidance devices that can be created using dovetail devices can be conceived without departing from the context of the present invention. Preferentially, the sliding link is on the YY′ axis.

[0083] Preferentially, the movable latching device 3 comprises a first stop in the first position 341, as seen in Fig. 9 or Fig. 10. More specifically, the button 31 is in the shape of a letter T when viewed from above, the horizontal bar of the letter T being the part that the user will activate with his / her finger, as seen in Fig. 9. The button 31 advantageously comprises a first pin 34, which projects from the vertical bar of the letter T formed by the button 31 in a direction similar to that of the foot 33. Preferentially, the pin 34 and the foot 33 extend in parallel directions, and advantageously in the same direction. Advantageously, the first pin 34 comprises a substantially flat surface perpendicular to the vertical bar of the letter T formed by the button 31, which surface forms a first stop in the first position 341. The first stop in the first position 341 is therefore advantageously parallel to the plane P.

[0084] Advantageously, the buttons 31 have reliefs that improve the quality of contact between the buttons 31 and the fingers of a user. These reliefs also enable the user to see where to place his / her fingers to unlock the tank 2.

[0085] Preferentially, the tank 2 comprises a first complementary stop device in the first position 232, as can be seen in Fig. 7. More specifically, the first complementary stop device in the first position 232 is comprised in the guide frame 23 which forms in this part a substantially rectangular window. The first complementary stop device in the first position 232 is therefore formed by a bar parallel to the first XX' axis. Preferentially, the bar is rectangular or square in cross section in order to provide substantially flat sides, in particular sides substantially parallel to the first stop device in the first position 341.

[0086] Thus, the first stop device of the first position 341 and the first complementary stop device of the first position 232 cooperate with each other in such a way as to prevent the translation of the mobile latch device 3 beyond the first position, in other words to provide a first position stop for the mobile latch device 3. As can be seen in figures 7 to 10, the cooperation in question is advantageously of plane-to-plane type. This allows a good contact that distributes the effort well and therefore guarantees a reliable, robust and durable first stop position over time. This limits the translational movement of the mobile latch device 3, which cannot go beyond its first position. As explained above, good stopping properties are all the more important, since the first position may correspond to a rest position, i.e. a position occupied very frequently by the mobile latch device 3.

[0087] Preferentially, the movable latching device 3 includes a second stop device, in particular in a first position 351, as seen in Figures 9 and 10. More specifically, the button 31 advantageously includes a second pin 35, which protrudes from a vertical bar of a T-shape formed by the button 31 in a direction that is opposite but parallel to the direction of the foot 33. Preferentially, the first pin 34 and the second pin 35 extend in parallel but opposite directions. In other words, the first and second pins 34, 35 extend on either side of the vertical bar of the T-shape formed by the button 31, as seen in Figure 9. Preferentially, the second pin 35 is parallel to the plane P.

[0088] Preferentially, the tank 2 comprises a second complementary stop device in the first position 233, as can be seen in Fig. 7. The second complementary stop device may then be formed by one wall of a notch made directly in the upper housing 21 of the tank 2. Preferentially, the second complementary stop device in the first position 233 extends longitudinally, parallel to the first axis XX'.

[0089] Thus, the second stop device at the first position 351 and the second complementary stop device at the first position 233 cooperate with each other in such a way as to prevent the translation of the mobile latching device 3 beyond the first position, in other words provide the mobile latching device 3 with a first position stop. Again, the cooperation is advantageously a plane-to-plane based cooperation, thus providing the same advantages as previously enumerated. The fact that the mobile latching device comprises two stops at the first positions 341, 351, each cooperating with two complementary stops at the first positions 232, 233 of the tank 2, thus makes it possible to provide the mobile latching device 3 with two first position stops. This makes it possible to optimally distribute the contact pressure between the two stops and thus improve the strength, reliability and durability of the mobile latching device 3. Furthermore, each of these stops makes it possible to keep the button 31 connected to the tank and to avoid accidental detachment of the mobile latching device 3 from the tank 2.

[0090] Preferentially, the mobile latching device 3 comprises a stop in the second position 332, seen in Fig. 10 and advantageously formed by the foot 33. More specifically, the stop in the second position 332 is formed by a surface of the foot 33 that is substantially parallel to the first stop in the first position 341 and preferentially parallel to the plane P. The stop in the second position 332 and the first stop in the first position 341 thus form two parallel stops that limit the translational movement of the mobile latching device 3.

[0091] Preferentially, the tank 2 comprises a complementary stop device in the second position 234, as seen in Fig. 7. The complementary stop device in the second position 234 is thus advantageously parallel to the first complementary stop device in the first position 232, for example by being arranged on opposite sides of the same bar of the guide frame 23.

[0092] And the stop device at the second position 332 and the complementary stop device at the second position 234 cooperate with each other to prevent translation of the movable latch device 3 beyond the second position, particularly when the user applies pressure to one or more buttons 31, forming a second position stop.

[0093] Preferentially, as mentioned above, the plane P forms a plane of symmetry for the movable latching device, which therefore comprises two buttons 31, two feet 33, two first pins 34, two second pins, two translation guides 331, two stop devices at the second positions 332, two latching means 333, two first stop devices at the first positions 341 and two second stop devices at the first positions 351, each of which is symmetrically arranged on either side of the plane P, as can be seen in Figures 9 and 10.

[0094] Advantageously, the mobile latching device 3 includes a resilient return device 32, seen in FIG. 9, designed to keep the mobile latching device 3 in its first position. The resilient return device 32 is preferentially a coil spring designed to keep the button 31 apart. However, other return devices could be conceived that would keep the button 31 apart, i.e. keep the mobile latching device 3 in the first position, without departing from the scope of the invention. For example, an electromagnetic device could be envisaged, in which the tank 2 would be equipped with a magnet and each of the buttons 31 would be made of a magnetic material (or vice versa). Preferentially, as shown in FIG. 9, the resilient return device 32 would be placed between the two buttons 31, which helps to simplify the construction and allows the resilient return device 32, in this case a coil spring, to transmit all the forces to the buttons 31 and only to the buttons 31. Preferentially, the mobile latching device 3 includes a housing 312, seen in FIG. 9, designed to accommodate the resilient return device 32. This ensures that the elastic return device 32 is held in place and guided when it is deformed. The housing 312 is advantageously formed by a groove extending from one end of the button 31, in this case the free end of the vertical bar of the T-shape formed by the button 31, and extending partially towards the inside of the button 31, preferentially along the second axis YY'. Thus, when the mobile latching device 3 is in its second position, the two buttons 31 are in contact and the footprint of the mobile latching device is zero, since the mobile latching device is fully embedded in the housing 312, i.e. inside the button 31. This helps to limit the footprint of the mobile latching device 3. As can be seen in FIG. 9, the elastic return device extends longitudinally along the second axis YY'.

[0095] Advantageously, as can be seen in FIG. 9, the second YY′ axis forms an axis of symmetry of the movable latching device 3.

[0096] As can be seen in FIG. 8, the first axis XX' forms an axis of symmetry with respect to the guide frame 23 and the plane P preferentially forms a plane of symmetry with respect to the guide frame.

[0097] Preferentially, the tank 2 comprises a fixed additional latching device 221, i.e. a non-movable and non-deformable additional latching device 221, seen in figures 5 and 6 and advantageously comprising a substantially rectangular tab protruding from the tank in a direction parallel to the first axis XX'. Preferentially, the additional latching device 221 is arranged at a longitudinal end of the tank 2, advantageously opposite the mobile latching device 3, itself arranged at another longitudinal end of the tank 2. This makes it possible to arrange the various latching points of the tank 2 on the body 1 as far away from each other as possible, which improves the stability and mechanical strength of the latching of the tank 2 to the body 1. Moreover, in the preferentially shown case in which the mobile latching device 3 comprises two latching means 333, this gives the tank 2 three latching points on the body 1, which corresponds to an isostatic assembly. Furthermore, the arrangement of the two locking means 333 on the second YY' axis and the arrangement of the additional locking device 221 on an axis parallel to the first XX' axis or optionally on the first XX' axis allows in particular a triangular arrangement of the locking points. The triangular arrangement of the points at which the tank 2 is locked to the body 1 makes it possible to improve the stability and the mechanical strength of the locking between the tank 2 and the body 1 and therefore the reliability of the locking between the two elements.

[0098] The body 1 therefore comprises additional complementary latching means 113, which can be seen in Fig. 2. The additional complementary latching means 113 for example comprises a substantially rectangular groove extending from the recess 111 inside the body 1 in a direction parallel to the first axis XX'.

[0099] The additional latching device 221 and the additional complementary latching means 113 are therefore designed to cooperate together when the tank 2 is in the latched position, the additional latching device 221 being preferentially a male latching device and the additional complementary latching means 113 being preferentially a complementary female latching means. Although the illustrated embodiment uses at least one additional complementary latching means 113 cooperating with at least one additional latching device 221, it is entirely conceivable that these elements may be added in order to enhance the mechanical strength of the latch.

[0100] As shown in figures 5 and 6, the tank 2 comprises at least one guiding device 24 designed to cooperate with at least one complementary guiding device 114 of the body 1 when the tank is in the latched position. This makes it possible to provide at least one guiding device between the latching means 333 and the additional latching device 221, which makes it substantially easier to latch the tank 2 to the body while providing an intermediate guiding means for the user. Furthermore, the guiding device 24 and the complementary guiding device 114 make it possible to strengthen the mechanical strength of the latch when the tank 2 is in the latched position, by preventing a translational movement of the tank 2 along the first axis XX'. This makes it possible to release the latching means 333 and the additional latching device 221, after which they only have to ensure a pull-out resistant attachment along a third axis perpendicular to the first axis XX'. This improves the strength and durability of the tank. The longer the length of the tank 2, the more important this intermediate guiding point becomes. Preferentially, the guide 24 is a female guide, for example a hole or a transverse notch in the shape of a semicircular hole, as shown. The complementary guide 114 is thus a complementary male guide, which may take the form of a semicircular (in the longitudinal direction) pin, as can be seen in Fig. 2. Advantageously, the tank 2 comprises two guides 24 and the body 1 comprises two complementary guides 114.
