JP7607568B2 - Tank with hanging device for steam hair styling device - Google Patents

Description

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

More specifically, the invention relates to the field of hair styling devices, including 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.

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

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

To perform 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. The user must therefore frequently, typically 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.

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.

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, for example, the risk of electrocution.

To limit this type of risk, various principles have been proposed for attaching the tank to the body of the hair styling device.

For example, as found in many commercially available devices and as shown in the patent application WO 2005/023363, one known solution consists of 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 removed. 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 remove 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 hands of the user as well as a considerable effort, both in terms of amplitude and force (to overcome the frictional forces). Also, with repeated assembly and removal 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 removal.

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.

Therefore, there is a need to improve existing devices, particularly with regard to the assembly of the tank to the body of the device.

International Publication No. 2017/008413

The present invention aims to improve the above-mentioned shortcomings.

One of the objects of the present invention is to provide a particularly reliable and robust tank for a hair styling device.

One object of the present invention is to provide a particularly durable tank for a hair styling device.

One of the objects of the present invention is to provide a hair styling device that is particularly durable.

One of the objects of the present invention is to provide a hair styling device that is particularly easy to handle, especially when assembling the tank to the body of the hair styling device or removing the tank from the hair styling device.

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.

One of the objects of the present invention is to provide a hair styling device that is particularly compact and lightweight.

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 a latch 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.

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 to be connected to the vaporizer and assembled to the main body in order to supply the liquid to be vaporized to the vaporizer, the tank being characterized in accordance with the above description.

The invention therefore relates to two separate products, in this case a tank for a hair styling device and a hair styling device, where the tank is designed to be connected to the hair styling device, so that there is a connection between them.

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.

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.

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.

"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 (e.g. by joining or welding).

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

In particular, the tank may be in a latched position, in which the tank is attached to the body of the hair styling device and the tank is coupled to, and advantageously sealed to, the body. This latched position allows the tank 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.

The tank may also be in an unlatched position. In this position, the tank 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 the tank, clean the tank, etc.

"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 includes 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.

The latching device of the present invention is movable between a first position that ensures that the tank is latched to the body and a second position that allows the user to assemble the tank to the body or 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 must move it between two positions) allows the tank to be moved from its latched position to its unlocked position, which avoids accidental removal of the tank from the body of the hair styling device. This significantly enhances the user comfort and safety of the hair styling device.

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.

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 to the hair to shape it, usually to straighten it. The device thus forms a hair straightening iron, which is a well-known device in itself and will not be described in further detail 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.

"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 envisaged 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.

Advantageously, the body includes a recess that is complementary in shape to at least part of the shape of the tank and designed to accommodate at least part of the tank when the tank is in the latched position, the recess including at least one complementary latching means. The tank 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 tank is firmly maintained in its latched position.

According to a preferred 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.

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: in fact, 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.

Preferentially, the tank extends longitudinally along a first axis and the movable 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 longitudinal axis of the tank 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 longitudinal axis of the tank is located in the palm of the hand, giving the tank an excellent support, and therefore the translational movement of the movable 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.

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

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

Also, according to this advantageous embodiment, the movable latching device preferentially includes a stop device in the second position, and the tank includes a complementary stop device in the second position, and the stop device in the second position and the complementary stop device in the second position cooperate with each other in such a way as to prevent translation of the movable latching device beyond the second position. Thus, the translational movement of the movable latching device is 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 movable 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.

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 tank 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 tank remains firmly attached to the body of the hair styling device. For this purpose, the movable latching device preferentially includes 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 can be considered, such as, for example, a ferromagnetic device. In the preferential case in which the movable latching device includes 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 structure from a mechanical point of view. Preferentially, the movable latching device includes 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 effort exerted on the buttons by the user. This enhances the mechanical strength of the movable latching device and the reliability of the tank.

According to one embodiment, the tank includes 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 proper distribution of the attachment points between the tank and the main body, thus improving the mechanical strength of the attachment.

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

FIG. 2 is a perspective view of the top of the tank of the device of FIG. 1. FIG. 4 is a perspective view of the tank of FIG. 3 with the upper housing of the tank hidden. FIG. 4 is a perspective view of the underside of the tank of FIG. 3 with the movable latching device hidden; FIG. 4 is another perspective view of the underside of the tank of FIG. FIG. 6 is a detailed view of FIG. 5 . FIG. 8 is a view similar to FIG. 7, but with all parts present. FIG. 4 is a perspective view of a movable latching device of the tank of FIG. 10 is another perspective view of the movable latch device of FIG. 9 .

The embodiment of the invention shown in the various figures is one in which the hair styling device, which is the subject of the invention, is a steam hair straightening iron. The tank 2, which is also the subject of the invention, is therefore 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.

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 forms a gripping area, preferentially over at least a part of their length. The hair styling device is shown in FIG. 1 in a closed position. The hinge 13 is therefore 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 ends of the first and second arms 11, 12, respectively, on opposite sides of the hinge 13. The hinge 13 is typically a shaft around which the first and second arms are attached.

1 and 2, the hair styling device includes 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 includes a first and a second arm 11, 12. It is also possible to envisage an alternative embodiment in which the hair styling device would include a second body, separate from the body 1, which houses the tank 2. The second body would then include the first and second arms 11, 12, as well as a 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.

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 portion of the shape of the tank 2. In other words, the recess 111 forms a hollow recess for at least a portion of the tank 2. The recess 111 is thus designed to accommodate at least a portion of the tank 2 when the tank 2 is in a latched position, as will be described in more detail below.

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

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 dismantle the tank 2 from the hair styling device, as can be seen in FIG. 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.

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 positioned 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, the user can fill it, in particular after removing the fill cap 26, as seen in FIGS. 5 and 6. More specifically, as seen in FIG. 4, the fill cap 26 includes a fill orifice cap 261 intended to provide a watertight seal for the fill 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, and 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.

Advantageously, as seen in FIG. 3, the tank 2 extends longitudinally along a first axis X-X', 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, 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 X-X'. Advantageously, the first arm 11 extends along the first axis X-X'. And in this advantageous case, as shown, the tank 2 can extend more than half the length of the first arm 11, which makes it possible to maximize 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.

The tank 2 also includes a connection device 25, seen preferentially in FIG. 5, which is intended to correspond to the complementary connection device 15 seen in FIG. 2 and which is arranged in the body 1, more specifically 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 specifically to the vaporizer device, which will be explained in more detail below. Preferentially, the connection device 25 is arranged at the longitudinal end of the tank 2, as seen in FIG. 5, and extends longitudinally parallel to the first axis X-X'.

As can be seen in FIG. 4, the tank 2 comprises a suction tube 251, which is 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, which do not allow all of the liquid to be sucked in, in other words, 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.

The tank 2 also includes 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 creation 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.

The venting device 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.

As seen in FIG. 4, the venting device 27 includes an umbrella or mushroom shaped valve. This device allows the weight of the liquid pushing against the valve cap or head to keep the valve depressed, thus preventing liquid from leaking from the tank 2. On the other hand, 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 returns to its initial position due to the weight of the liquid, as explained before.

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 and definitively 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.

As will be appreciated, the above 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.

As can be seen in FIG. 5 and in more detail in FIG. 7, the tank 2 advantageously includes a guide frame 23, which itself preferentially includes different bars making it possible to provide various guiding and hooking functions, as will be described 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.

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. Systems of this kind are 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, like a mist, without changing the state of the liquid.

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 main body 1, may also include a flow generating device, 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.

According to the invention, the tank 2 includes 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 therefore 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.

10, the movable latching device 3 includes at least one latching means 333. More specifically, the movable latching device 3 includes preferentially a foot 33, which itself includes a latching portion that projects from the foot 33 and forms a rib intended to be latched on a complementary portion, the rib thus forming the latching means 333. In other words, the latching means 333 is a male type of latching means, whose shape is substantially rectangular. Advantageously, as shown, the movable latching device 3 includes 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 X-X' of the tank.

The at least one latching means 333 is designed to allow the tank 2 to be latched to the body 1, i.e. to maintain the tank 2 in the latched position. Preferentially, the latching 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 technologies, which operate on the basis of elastic deformation of such a latching device, the rigidity of the latching 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 latching means 333 is eliminated. The reliability and lifespan of the latching means 333, and thus of the tank 2, and thus of the hair styling device, are increased accordingly.

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

The movable latching device 3 is movable between a first position that ensures that the tank 2 is latched to the body 1 and a second position that allows a user to assemble the tank 2 with the body 1 or 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.

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

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 described in more detail below.

In the various figures, the movable latching device 3 is actually shown in this second position.

As can be seen in the different figures, preferentially, the movable latching device 3 includes 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 decouple 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), thus moving the movable latching device 3 from its first position to its second position or vice versa. In other words, the movable latch device 3 can therefore be moved between a first position and a second position.

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

Preferentially, as can be seen in FIG. 8, the movable latching device 3 is translationally movable relative to the tank 2 along a second axis Y-Y' perpendicular to the first axis X-X'. In other words, the translational movement of the movable latching device 3 thus occurs perpendicular to the longitudinal direction of the tank 2. In the preferential case in which the movable latching device 3 comprises two buttons 31, this means that the two buttons 31 are translationally movable along the second Y-Y' axis. Such an arrangement is thus a completely noteworthy ergonomic improvement, since it is possible for the user to handle the tank 2 and its latching system, i.e. the movable 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 X-X' substantially perpendicular to his/her arm. The movable 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.

As can be seen in Figures 9 and 10, the movable latching device 3 includes a plane of symmetry P perpendicular to the second Y-Y' axis. In other words, the plane P may include the first axis X-X'. Thus, the movable latching device 3 is completely symmetrical with respect to the plane P. The movable latching device includes two subassemblies disposed on either side of the plane P and symmetrically disposed 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.

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.

Preferentially, the movable latch device 3 includes a translation guide device 331, advantageously formed by a T-shaped vertical bar of the foot 33. The tank 2 therefore includes a complementary translation guide device 231, advantageously formed by a bar of the guide frame 23, as can be seen in FIG. 7. The translation guide device 331 and the complementary translation guide device 231 therefore cooperate with each other to translationally guide the movable latch device 3 in the tank 2, more specifically in the guide frame 23.

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, and the second Y-Y' axis is 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 guiding devices that can be created using dovetail devices can be conceived without departing from the context of the present invention. Preferentially, the slide link is on the Y-Y' axis.

Preferentially, the movable latching device 3 includes a first stop at 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, and the horizontal bar of the letter T is the part that the user will activate with his/her finger, as seen in FIG. 9. The button 31 advantageously includes a first pin 34 that protrudes 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 includes a substantially flat surface perpendicular to the vertical bar of the letter T formed by the button 31, which surface forms a first stop at the first position 341. The first stop at the first position 341 is therefore advantageously parallel to the plane P.

Advantageously, the button 31 has reliefs that improve the quality of contact between the button 31 and the user's fingers. These reliefs also allow the user to see where to place his/her fingers to unlock the tank 2.

Preferentially, the tank 2 includes a first complementary stop device at the first position 232, as can be seen in FIG. 7. More specifically, the first complementary stop device at the first position 232 is included in the guide frame 23 which forms a substantially rectangular window in this part. The first complementary stop device at the first position 232 is thus formed by a bar parallel to the first X-X' 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 at the first position 341.

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 movable latch device 3 beyond the first position, in other words to provide the movable latch device 3 with a first position stop. As can be seen in Figs. 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 movable 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 movable latch device 3.

Preferentially, the movable latching device 3 includes a second stop device, in particular in the first position 351, seen in Figs. 9 and 10. More specifically, the button 31 advantageously includes a second pin 35, which protrudes from the vertical bar of the T, formed by the button 31 in a direction 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, formed by the button 31, as seen in Fig. 9. Preferentially, the second pin 35 is parallel to the plane P.

Preferentially, the tank 2 includes a second complementary stop device at the first position 233, as 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 at the first position 233 extends longitudinally, parallel to the first axis X-X'.

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 movable latch device 3 beyond the first position, in other words provide the movable latch 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 movable latch device includes two stop devices at the first positions 341, 351, each of which cooperates with two complementary stop devices at the first positions 232, 233 of the tank 2, thus makes it possible to provide the movable latch 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 movable latch device 3. Furthermore, each of these restraints allows the button 31 to remain connected to the tank and avoids accidental detachment of the movable latching device 3 from the tank 2.

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

Preferentially, the tank 2 includes 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.

The stop device at the second position 332 and the complementary stop device at the second position 234 then 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.

Preferentially, as mentioned above, the plane P forms a plane of symmetry for the movable latching device. The movable latching device therefore includes 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 Figs. 9 and 10.

Advantageously, the movable latching device 3 includes a resilient return device 32, seen in FIG. 9, designed to keep the movable 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 movable 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 movable 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 Y-Y'. Thus, when the movable latch device 3 is in its second position, the two buttons 31 are in contact and the footprint of the movable latch device is zero, since the movable latch device is fully embedded in the housing 312, i.e. inside the button 31. This helps to limit the footprint of the movable latch device 3. As can be seen in FIG. 9, the elastic return device extends longitudinally along the second Y-Y' axis.

Advantageously, as can be seen in FIG. 9, the second Y-Y' axis forms an axis of symmetry for the movable latching device 3.

As can be seen in FIG. 8, the first axis X-X' 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.

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 Figs. 5 and 6 and advantageously comprising a substantially rectangular tab protruding from the tank in a direction parallel to the first axis X-X'. Preferentially, the additional latching device 221 is arranged at a longitudinal end of the tank 2, advantageously opposite the movable latching device 3, which is 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 movable 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 Y-Y' axis and the arrangement of the additional locking device 221 on an axis parallel to the first X-X' axis or optionally on the first X-X' axis, in particular allows the locking points to be arranged in a triangle. 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 mechanical strength of the lock between the tank 2 and the body 1 and therefore the reliability of the lock between the two elements.

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

Thus, the additional latching device 221 and the additional complementary latching means 113 are 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. The illustrated embodiment uses at least one additional complementary latching means 113 cooperating with at least one additional latching device 221, but it is entirely conceivable that these elements may be added in order to enhance the mechanical strength of the latch.

5 and 6, the tank 2 includes 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 X-X'. 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 X-X'. 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, as shown, a transverse notch in the form of a semicircular hole. 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 includes two guides 24 and the body 1 includes two complementary guides 114.
