Description

  The present invention relates to a hair styling device that can use steam and is designed to be styled through contact with hair, and more particularly to curl human hair in addition to straightening.

  Traditionally, there are two different types of hair styling devices for straight or curl, whether heated or unrolled, rollers, strainers or straight irons, and curlers or curl irons.

  Straight iron or curl iron type devices generally comprise two jaws that pivot relative to each other about a common axis, each jaw having an end that supports a treatment surface, At least one is heated and the other, in particular, contacts the hair to the first treatment surface by switching from an open position of the jaw that allows the insertion of the hair to a closed position where the hair contacts the heating section. Provided to let you.

  The strainer has two identical flat heating surfaces that sandwich the hair at the first end of the strainer jaw. In addition, the other end of the jaw forms two handles that act as a gripping region and allow switching from the open position to the closed position. The switching is done manually by pushing the two combined handles of the device towards each other in order to bring the treatment surface into contact with the hair. The hair strand is straightened by moving the device along the strand from the root toward the hair tip in a linear movement of the closed device.

  The curler has a surface formed by a cylindrical heating mandrel that is accompanied by a single flap that pinches the end of the tuft by swirling in the mandrel before wrapping the entire tuft around the mandrel. The hair strands are curled by wrapping the strands at least partially around the treatment surface and by applying heat primarily to set the curls statically.

  In each of these two devices, there is an option to also use steam applied to the hair. This makes it possible to improve hair styling, to last longer hair styling, to maintain moisture in the hair, to care for the hair, or to assist the penetration of cosmetics into the hair .

  There are already straight devices that work with steam, such as those described by the applicant in the patents, US Pat. The strainer of the second document mentioned is shown in FIG. The strainer has a straight iron with two identical flat straight plates facing each other and a vapor discharge hole. A steam strainer such as that described in US Pat. No. 6,057,056 and depicted in the present application is presented in FIG. The present application, which is currently available on the market, is completely satisfactory in terms of straightening and can produce sufficient vapor output to fully treat the hair fibers. Nevertheless, in order to produce excellent straightening and substantial steam output, this device is technically optimized but occupies a rather large space compared to conventional straight irons Accommodates many internal elements with configuration. In fact, the jaws that produce steam contain the steam generation chamber. Thus, the two housings or the two shells holding the plate and the steam generation chamber each have an outer cover having the same width or the same greater width when viewed in cross section. However, the two covers, in particular with regard to the function of the steam, delineate an asymmetrical and relatively flat external form, i.e. the steam cover and the deflector plate facing the hole are positioned in the outer cover.

  Thus, if the user wants to use this device to form a curl by wrapping a tuft around one or both of the covers, the user will form a well-rolled curl or be very regular The curl cannot be formed or cannot be slid in a regular manner as it flows through the device in order to restore the curl once formed.

  Another object of the present invention is a device that can style the hair by contact with the hair, use steam, is safe, and does not burn the user's scalp or hands.

  These objects are in accordance with the first aspect of the present invention a hair styling device for curling or straightening hair, wherein the first elongate jaw and the second are pivotably movable relative to each other. An elongate jaw, the first jaw having a first housing that supports a first inner planar treatment surface, and the second jaw being a second inner planar treatment. A first elongate jaw and a second elongate jaw and at least one inner treatment surface having a second housing for supporting the surface, the inner surface being designed to sandwich the lock of hair; And at least one heating element designed to heat the hair styling device. In this apparatus, the maximum width (l1) of the first casing is 90% or less of the maximum width (l2) of the second casing. This feature, unlike any conventional strainer specification that is expected to have the same housing width, makes it possible to provide different housings, so one housing or both housings in the closed position In both cases, the device is kept simple and not too bulky, while making it possible to create curls of different sizes around each other. The maximum width will be considered as a relevance for the size ratio between the two housings. In this device, at least one of the first casing or the second casing is asymmetric with respect to the median plane in the longitudinal section of the first casing or the second casing. . This feature makes it possible to obtain curls and the radius of the curl curve is not constant towards a more natural effect. According to the present invention, the second jaw comprises means for releasing vapor directed towards the first housing and adjacent to the second inner treatment surface. This makes it possible to provide steam treatment prior to straight processing in the recommended order through the strainer across the tuft. The technical components that make it possible to generate and extract steam are enclosed inside the larger jaw, which is the wider jaw. The means for generating steam comprises at least one fluid container in fluid communication with the steam generation chamber, the steam generation chamber being by heating means designed to also heat the treatment surface or dedicated to the steam generation chamber only It can be heated by a heating means.

  More specifically, according to the present invention, the maximum width (l1) of the first housing is between 75% and 85% of the maximum width (l2) of the second housing, preferably 80. %be equivalent to. This makes it possible to limit the overall external bulk of the two covers or two shells holding the hair treatment part while each housing contains all of the internal technical components To do.

  According to the present invention, when the jaw is in the closed position, the median plane (P1) in the longitudinal section of the first casing is parallel to the median plane (P2) in the longitudinal section of the second casing. And can be distinguished. This means that in a cross section perpendicular to the longitudinal axis of the strainer, the cross section is not symmetric at right angles to the straight plane (Pl). A straight plane (Pl) is defined in that it includes a flat straight region formed by two flat processing surfaces, one in contact with the other, in the closed position of the device. Each of the two housings is disposed on either side of the straight plane. Accordingly, in the processing area, the first housing is displaced from the second housing. This asymmetry or deviation allows the device to be provided and the use of the device is intuitive to the user in one particular direction. This configuration intuitively guides the user towards the most efficient method of use.

  More specifically, according to the present invention, the distance between the two median planes (P1, P2) is between 5% and 20% of the value of the maximum width (l2) of the second housing. , Preferably equal to 10%. This deviation is significant enough to guide the user ergonomically.

  According to the present invention, when the jaw is in the closed position, one of the two longitudinal edges of the first casing is the second casing disposed on the same side of the second casing. It is flush with the longitudinal edge. This is because, in the closed position, the two edges on the same side of the device (usually as in the strainer) face each other, more importantly, the two edges on the other side of the housing. Will be offset relative to each other. On the side where the edges are flush, the curve formed by the contours of the two shells or housings is relatively symmetric with respect to the straight plane (Pl). The straight plane (Pl) is a plane including a straight region formed by two surfaces in contact with each other. These two flush edges allow the tuft to be wrapped around the two housings in the closed position of the device to form a large curl. These two edges, which are flush with each other, make it possible to form loosely well-rounded, so-called regular curls, with undesired traces and with a device that is relatively small for the size of the curl obtained to enable.

  According to the invention, the inner processing surfaces are flat and identical and face each other in the closed position and are arranged in respective housings of the inner processing surface adjacent to the flush edge. By "adjacent", considering the limits of production and taking into account the presence of any small bars that may be between the housing and the processing surface, as close as possible or as close as possible Is meant. This means that straightening is performed on the side of the flush edge. While in use in the tuft being treated, these edges will be placed on the scalp side, a combination of the various treatments provided by the device (straightening, steaming, and combing or brushing) Among other things, the hair can be finally subjected to a straightening treatment, and the hair can be made to have a perfect finish to the hair style.

  More specifically, according to the present invention, each of the two longitudinal edges is mounted with at least one small rod that protrudes toward the interior of the housing and is made of the same material as the housing. Is done. This small bar protrudes against the contour of the housing and is oriented towards the interior of the housing. This small rod ideally forms two surfaces (and not chamfers) that are at right angles, one of which is parallel to the treatment surface or the surface of the adjacent straight plate . This small bar allows the tufts to be pulled and held when the device is closed, to allow the tufts to undergo a wrinkle effect, and to bend the tufts more easily. This effect, also known as “bolduc” (gift ribbon) in French, can be compared to the effect of sliding the heel blade across the “Bouldac” ribbon to form a curl. The small bars are identical and are placed at the same location in the jaws to create the same “boulder” effect, depending on the strainer's upward or downward slope. The small bar has a specific design and surface structure so that the hair can have a frictional force on the upper small bar relative to the frictional force on the outer surface of the jaw. The surface structure can be a rough coating.

  According to the invention, the width of each inner treatment surface is between 40% and 60% of the maximum width (l1) of the first housing, preferably between 40% and 50%, Preferably it is approximately equal to 45%. About half of the width of the housing is occupied to make the main processing step, which main processing step is necessary to straighten the tuft that can be curled later depending on the user's choice It is a step.

  More specifically, according to the present invention, the first casing is formed at the inner contour of the first casing, and generally faces the vapor discharge means of the second casing at the closed position. A deflecting plate is disposed. This deflector has several functions, i.e. it protects the scalp from any jet of steam that can burn the scalp, directs the steam towards the hair, the hair is passed more than twice, Therefore, a better process is received. The angle and arrangement of the deflection plates are such that the size of the deflection plates is minimized as compared to the closest prior art while maintaining the function of the polarizer.

  According to the present invention, the second housing comprises a comb or brush oriented toward the first housing and adjacent to the second inner processing surface. When the combing or brushing function is provided in addition to the straightening function, the order in which the hair is treated is as follows: combing or brushing and then straightening or steam is formed Is steamed, then combed or brushed and then straightened.

  More specifically, according to the present invention, the first housing is formed in the inner contour of the first housing which is arranged in the closed position and generally facing the comb or brush of the second housing. It has a groove. This is a device that, in the closed position, retains at least the free ends of the combs or at least the free ends of the rows of brush hairs while limiting the bulk as much as possible and in any case can damage the combs. It makes it possible to protect the end of an accessory (comb, brush, etc.) from any excessive pulling caused while passing along the tuft in the closed position. The comb should not contact the upper housing before contacting the heating plate.

  According to the invention, the first handle of the first jaw and the second handle of the second jaw each have a width (Lp) that is always smaller than the maximum width (l1) of the first housing. . This allows for easy gripping for any size hand. Thus, the handle extends along the longitudinal axis of the respective housing. The edges of the housing that are flush with each other are each arranged in particular (along a single straight line), in particular with the corresponding edges of the handle. The asymmetry of the device is also noticeable at the handle.

  According to the present invention, the outer surfaces of the first housing and the second housing that at least cover the processing region formed by the processing surface are essentially smooth. This is the case when the tuft is wrapped around one or both of the housings, such as Charmilles 0 or 3, and when the tuft needs to be released without affecting the shape of the curl from which it was made , You can slide the tuft as much as possible. The surface roughness (Ra) referred to as “essentially smooth” ranges between 0.2 μm and 2 μm, more specifically between 0.2 μm and 0.5 μm. At least one gripping region may be disposed on the outer surface of the housing. This gripping area is adapted to limit heat transfer to provide a different approach to handling heat transfer without the risk of burns by holding the jaws by the housing rather than by the handle. The For example, the surface of the gripping region may be made from a different material or may have a different surface structure than the rest of the outer surface of each housing.

  According to the invention, in the cross section, the line defined by the outer contours of the first housing and the second housing is a rounded curve with no bending position. According to certain aspects, the line is not visually flat. This makes it possible to provide a reduced bulk device that can form curls and has a generally rounded overall contour. For reasons of these bulks and the different deposition of the two housings, the outer contour is nevertheless not circular. According to the present invention, the apparatus comprises a fluid container, a steam generating means in fluid communication with the steam discharge means, and an actuator designed to control the steam generating means. This makes it possible to control the vapor separately from the heating of the treated or straight surface. The user has a choice through this actuator.

  According to the invention, the steam generating means comprises an electric pump and the actuator is designed to control the electric pump. This makes it possible to control the supply to the steam generation chamber independently of the heating of the treatment surface or straight surface. Thus, if the user wants to stop generating steam, the user presses an actuator or switch to stop the operation of the electric pump, but the heat in the steam generation chamber varies depending on the operation of the switch. Will remain unsuccessful and continue. When the user tries to use the steam again, the user activates the switch, which restarts the electric pump and keeps the steam generation chamber at the proper temperature while the pump was stopped Therefore, the steam will be operated immediately. The user has the choice between stopping the steam immediately and restarting the steam immediately through this actuator.

  It should not be construed as limiting in any way, and it will be easier to understand the present invention upon review of the embodiments illustrated herein.

  The same reference numbers are used to indicate the same or even similar components that are depicted in multiple figures.

  As depicted in all of the drawings, including FIG. 1, depicting the prior art, the hair styling device (1) comprises a first jaw (2) and a second jaw that are arranged facing each other. Part (3). Each jaw can be at least functionally disassembled into two parts: a housing that holds the hair treatment body and a handle for the user to grip the housing. Each housing is formed as a single piece. The housing and handle can also be a single article as an extension of each other. Thus, the first jaw (2) can be formed from the first housing (6) and the first handle (6 ′), and the second jaw (3) is the second housing (7) and It can be formed from a second handle (7 '). The first inner processing surface (4) is supported by the first jaw (2), more specifically by the first housing (6), and the second inner processing surface. (5) is supported by the second jaw (3), more specifically by the second housing (7). The two jaws (2, 3) are connected to switch between an open position and a closed position, in which the inner treatment surface (4, 5) sandwiches the hair strands. The first hair treatment surface (4) and the second hair treatment surface (5) are flat and complementary which move to fit generally together so as to sandwich the hair strand when the device is in the closed position. Surface, thus allowing the tufts to be straightened when they are slid through in a linear motion. The two processing surfaces are essentially symmetric with respect to the straight plane when the device is in the closed position. Similarly, the heating elements on each processing surface are essentially symmetric with respect to the straight plane when the device is in the closed position.

  The first jaw (2) and the second jaw (3) are connected by a hinged connection, the maximum opening angle (α) of the two jaws being between 5 ° and 60 ° Or even between 10 ° and 20 °, preferably approximately equal to 15 °. The device is still depicted in the “open” rest position here, but can also be in the “closed” rest position as depicted in US Pat. The device is assembled to pivot to the other end between an open position allowing insertion of the hair between the treatment surfaces and a closed position where the hair is in contact with the two treatment surfaces, and the device is integrated into the treatment surface. And a means for returning half of the handles to be pressed. Two jaw pivots that direct the treatment surface can be located at the jaw ends (as depicted here) or to provide a scissors-like connection to the device. It can be placed roughly in the middle.

  The material forming the treated surface (4, 5) is made from a metal and / or ceramic and / or glass and / or plastic material and / or fiber article. At least one of the first housing and the second housing has a single heating element designed to heat the corresponding treatment surface through contact and to heat the coating by radiation. . The treated surface can be raised to temperatures between 130 ° C and 230 ° C. The housing and the external handle are integrated to form a jaw. The material forming the external part of the housing, or even the external part of the handle, can be a plastic such as glass fiber reinforced PBT (polybutylene terephthalate). It is important that this material has a very smooth surface. The material forming the internal part of the housing, or even the internal part of the handle, can be a plastic such as glass fiber reinforced PET (polyethylene terephthalate).

  As depicted in FIG. 4, the device (1) comprises at least one heating means (41) for heating the first treatment surface (4). In certain embodiments, the apparatus (1) also comprises heating means (51) for heating the second treatment surface. The one or more heating means (41, 51) are located flat with respect to the treatment surface (4, 5) or are placed inside the element comprising the treatment surface (4, 5) (positive Temperature coefficient) Can be a heating element, which can be a thermistor or a ceramic element.

  As depicted in FIG. 4, the apparatus (1), in one embodiment, comprises a steam generation chamber (81) and heating means (or heating elements or heater elements) (82) for the steam generation chamber. Means (80) for generating steam from the fluid. The one or more steam generation chambers are made of aluminum and may comprise a vapor discharge means (31) that may be formed by one or more steam delivery holes, for example a row of holes. One or more steam generation chambers (81) may lie flat in direct or indirect contact with corresponding heating elements (82). Proper pressing of the heating element (82) and thereby proper operation of the heating element (82) is ensured, for example, by a spring-loaded strip (not depicted).

  A temperature sensor may preferably be placed above the fluid inlet to the chamber. The heating means (82) of the steam generation chamber is a PTC (positive temperature coefficient) thermistor or ceramic element that lies flat against one of the walls or is placed inside the element that forms the treatment surface. There may be at least one possible heating element, and the heating means (82) may be the same as or separate from the heating means of the treatment surface. The means (31) for delivering or releasing the vapor has a series of vapor discharge holes arranged laterally on the first treatment surface (4) and preferably installed shortly after the treatment surface (4). obtain. Alternatively or additionally, the vapor delivery means has a series of holes disposed in the treatment surface. The vapor discharge flow is between approximately 3 g / min and 4 g / min, and preferably equals approximately 2.5 g / min. The internal structure of the device, in particular the internal structure of the steam generating means, is described in full detail in the applicant's patent document 4.

  As depicted in FIGS. 2, 3 and 4, the hair styling device (1) for curling and straightening the hair is the outermost of the hair styling device (1) of the first housing (6). In large (l1), it is 90% or less of the maximum width (l2) of the second casing (7). More specifically, the maximum width (l1) of the first housing (6) is between 75% and 85% of the maximum width (l2) of the second housing (7), preferably 80. %be equivalent to. These maximum widths are essentially constant across the enclosure, except at the edge of each enclosure, which is why the range of values is indicated. Further, FIG. 4 is a cross-sectional view generally in the middle of the housing.

  In the closed position of the jaws (2, 3) as depicted in FIGS. 3 and 4, even the median or sagittal plane (P1) in the longitudinal section of the first housing (6) The casing (7) is parallel to the median plane (P2) in the longitudinal section and is separate from the median plane (P2). The distance between the two median or sagittal planes (P1, P2) is between 5% and 20% of the width of the maximum width (l2) of the second housing (7), preferably 10% be equivalent to. Therefore, the main bodies of the two housings are not symmetrical along the transverse longitudinal plane and are offset.

  The profile of the device is clearly asymmetric, thoughtful for both reducing the bulk of the internal elements and facilitating the process of using the strainer to form curls of different sizes. used. As depicted in FIGS. 3 and 4, when the jaws (2 and 3) are in the closed position, one of the two longitudinal edges (61) of the first housing (6) It is flush with the longitudinal edge (71) of the second housing (7) arranged on the same side of the housing (7). The transverse longitudinal plane P4 and the transverse longitudinal plane P5 are median planes of the inner treatment surface (4) and the inner treatment surface (5), respectively. In the cross section depicted in FIG. 4, this plane (P4) is parallel to the planes P1 and P2, and is shifted outward with respect to the planes P1 and P2. The planes P4, P1, and P2 are parallel to each other and are each perpendicular to the straight plane (Pl). Further, the first casing (6) and the second casing (7) of this example are also asymmetric with respect to the respective median planes (P1, P2) in the longitudinal section.

  As can be seen, the inner processing surfaces (4, 5) are flat, identical and facing each other in the closed position, and each housing is close to a flush edge (61, 71) on the side. Located on the body (6, 7). In FIG. 4, flush lines are shown, which extend tangent to the edges (61, 71) of the housing or cover that are flush with each other. This line is perpendicular to the straight plane (Pl). The curves of the contours (li6, li7) of each housing (6, 7) form an arc that is essentially continuous at the flush edges (61, 71), so that the value of the arc is It is approximately 15 mm.

  Each of the two longitudinal edges (61, 71) protrudes towards the inside of the device and is preferably a small bar (62, 72) made of the same material (such as PBT plastic) as the housing (6, 7). ) Is provided inside. These small bars are arranged in the same way in both housings, as depicted in FIG. The small bars make it possible to apply tension to the hair to give a “Boldac” ribbon effect that slides on one of these small bars during the straightening action. This is a first method of forming inward or outward curls, depending on which one of the small bars that are placed below and some above the strainer is used. It is.

  As depicted in FIGS. 2 and 4, the width (l) of each inner processing surface (4, 5) is between 40% and 60% of the maximum width (l1) of the first housing (6). %, Preferably between 40% and 50% and even approximately equal to 45%.

As shown in FIG. 4, a non-limiting example of the dimensions of the device according to the present invention is as follows.
l1: Maximum width of the first casing (6) = 45 mm
l2: Maximum width of the second casing (7) = 52 mm
h1: Maximum height of the first housing (6) = 23 mm
h2: Maximum height of the second casing (7) = 32 mm
l: Width of each inner treatment surface (4, 5) = 25 mm
r: radius of a curve defined by the lateral profile of each side of the first housing (6): about 14 mm

  The strainer according to the present invention comprises a second jaw (3) with vapor discharge means (31) oriented towards the first housing (6) adjacent to the second inner treatment surface (5). )have. To be precise, this is because the first jaw (2) comprises only one straight plate for hair treatment, while the second jaw is at least with the straight plate for hair treatment. It means having one additional hair styling function. At least one additional hairstyle feature is listed below: steaming, combing, brushing, ionizing, pulling with a small stick made from a silicone type material Or one or more functions selected from applying tension with a small movable rod that vibrates, for example. Thus, the present invention provides an additional hair styling function to the straightening function and the ability to form at least two different sized curls, or even at least three different sized curls. Provide to the device. To do this, additional hair styling functions are incorporated into the wider of the two housings. The present invention resides in the best reduction of the width of the jaw housing with only the function of straightening, without causing malfunction, in terms of either safety or effectiveness of the complete hair styling device. As a result, in addition to curl formation, the “release” of the curl also constitutes an additional limitation in the size and shape of the housing.

  When the steam function is incorporated into the second jaw (3), the first housing (6) is formed at the inner contour of the first housing (6) and in the closed position the second It may be important to have a deflecting plate (21) arranged generally facing the vapor discharge means (31) of the housing (7). This deflection plate makes it possible to protect the scalp from any unwanted jets of steam or condensed drops of hot water. This deflecting plate (21) makes it possible to direct the steam towards the hair and the hair will be passed twice by the steam. The deflecting plate in the prior art depicted in FIG. 1 was very wide and flat and covered the entire size of the jaw that the deflecting plate was facing. The sizing of the deflection plate (21) of the present invention depicted in FIG. 4 has been carefully selected by the inventor to retain this function, and the width dimension is the width dimension of the vapor discharge hole (31). Just as small as possible to cover. Furthermore, the shape of this deflecting plate has changed, the shape of the polarizing plate is no longer flat as depicted in FIG. 1, and the internal contour of the first housing (6) acts as a deflecting plate. So that it is tilted upwards.

  As depicted in FIG. 4, the second housing (7) is a comb or orientated facing the first housing (6) and adjacent to the second inner processing surface (5). A brush (32) is provided. In this case, the first housing (6) is formed at the inner contour of the first housing (6) and generally faces the comb or brush of the second housing (7) in the closed position. May have a groove (22) arranged in a row. In this way, the comb clearly separates the overall thickness of the tuft without the function of a combination that occupies excess space.

As depicted in FIGS. 2 and 3, the first handle (6 ′) of the first jaw (2) and the second handle (7 ′) of the second jaw (3) are: Each of the minimum widths of the two housings (6, 7) has a width (lp) that is always smaller than the maximum width (l1) of the first housing (6). As a result, the edges of the housings (6, 7) that are flush with each other, in these cases, handle to form a matching alignment line (L _ali ) as shown in FIG. Aligned with the same side edge. It can be seen that this alignment increases the ergonomics of the device and allows the device to be operated with any size hand.

  The outer surfaces of the first housing (6) and the second housing (7) are essentially smooth. The coefficient of friction was measured using a contour roughness measurement in an area designed to wind the curl as follows.

  a) Ra measurement at the “flat” upper part or the horizontally tangent part of the outer shell (6) depicted in FIG.

  In the longitudinal direction, they are 0.24 μm, 0.23 μm, and 0.22 μm, and the average is 0.23 μm.

  In the horizontal direction, they are 0.22 μm, 0.44 μm, and 0.27 μm, and the average is 0.31 μm.

  b) Ra measurements on the left and right sides of the outline (6) depicted in FIG.

  In the longitudinal direction, they are 0.24 μm, 0.23 μm, 0.43 μm, and 1.63 μm, and the average is 0.24 μm, and the local peak extends to 1.63 μm.

  The roughness meter used is from the brand of Mitutoyo number JP1010. The statistical criterion Ra is statistical, and the statistical criterion Ra is an average mathematical deviation from the average line.

  This allows curls to be easily wrapped and “released” without damaging the hair strands.

  In the cross-section as depicted in FIG. 4, the line defined by the outer contours of the first housing (6) and the second housing (7) is a rounded curve with no bending position It is. The main part of the work is established by the device, with the overall volume of the internal components, without the position of the bends at all, so that the most rounded and flowable possible contours of the housing so that it is the best possible It was to be determined according to safety and effectiveness measures. It should be noted that in the cross section there are no flat lines that are visually detectable by the naked eye. In the first housing, the first housing has an arc on a side smaller than an arc on the side of the second housing. The curved radius of each side of the first housing (6) is substantially the same. This makes it possible to form the most round possible curls. This also makes it possible to avoid having corners in devices that are brittle to impact. In cross section, the outer contour of the first housing (6) is a reduction of the outer contour in the cross section of the second housing (7) at a rate of approximately 0.8.

  According to the present invention, the apparatus is designed to control the fluid container (83), the steam generating means (80) in fluid communication with the steam releasing means (31), and the steam generating means (80). Actuator (85). More specifically, the steam generating means (80) comprises an electric pump (84) and the actuator (85) is designed to control the electric pump (84). This makes it possible to control the supply to the steam generation chamber (81) independently of heating the treated surface (4) or the straight (5) surface. The user has a choice with this actuator (85). If the user wants to make a curl with or without steam, the user pushes the actuator directly. The electric pump can be a peristaltic pump where the actuator (85) will control the motor.

  6 and 6a depict an alternative embodiment of the present invention. The device has a two-part configuration: a straight iron as described in the present invention presented above and a remote base. This configuration is described in the patent document 5 of the applicant. Thus, the device (1) designed for hair styling with a base (1000) comprises a (main) fluid container (83) and a handheld unit (100) comprising means (80) for generating vapor from the fluid. ), Means for delivering steam to the hair (31), and at least one designed to transport fluid and disposed between the main fluid container (83) and the steam generating means (80) A hand-held unit (100) comprising at least one first treatment surface (4) designed to contact the hair and from a fluid The means (80) for generating steam is exclusively provided in the handheld unit (100). The base is referred to as “remote” from the handheld unit and may be placed on the work surface. The base includes a receiving portion (1001) for holding the handheld unit or handpiece (100) when the handheld unit or handpiece (100) is not in use, and a cover (2030) for adding fluid It has. The cover (2030) may be fully movable to replace the demineralization means (2000) (cartridge) when needed. A portion of the base may be transparent so that the user can be visually warned that the ion exchange resin is no longer operational and is changing color. Part of the base is provided with demineralization means (2000) that make it possible to reduce the calcium component of the fluid added to the base. This demineralization means (2000) consists of an intermediate container that receives the "raw" fluid and a container (83) that contains the "purified" fluid intended for the hair styling device (1). Arranged between.

  As depicted in FIG. 6a, the base (1000) comprises demineralization means (2000) and a fluid container (83), where the fluid flows between a fluid tube (121 ′) and an electrical wire (121 ″). The means for carrying the fluid from the container at the base to the steam generation chamber of the handheld unit (100) comprises an electric pump (84), in this case a peristaltic pump. The motor (84 ′) of the electric pump (84) is here controlled by an actuator (85) located at the base (1000).

  Alternatively, the device can take the configuration depicted in FIG. 2 with a single device with an integrated fluid container and an integrated steam generation actuator (85).

DESCRIPTION OF THE INVENTION During Operation During operation, the user connects a power source to the device and a PTC or ceramic type heating element begins to heat the surface designed to come into contact with the hair. , When there is a steam function, another heating element (or the same heating element) starts to heat the steam generating means (80) and the user grabs the device by hand and receives the hair strand to be treated Apply the device to pinch.

  Because the two housings are asymmetric, the placement of the device in the chamber is important and the user must place and close the strainer so that the two flush sides are as close as possible to the scalp. The direction is depicted in FIG. Next, the user slides the hair along the tress in a linear fashion in the direction indicated by the arrows depicted in FIGS. 2 and 3 in the first housing (6). Conventional straightening steps can be implemented.

  When the user attempts to form a small sized curl, the user proceeds as follows. With the device (1) in the open position, the user wraps the lock of hair around the first housing (6), then closes the strainer as close as possible to the scalp and closes the device (1). Hold for a few seconds and then “release” the tuft by sliding the device (1) towards the free end of the tuft. This makes it possible to form small sized curls.

  When the user attempts to form a larger sized curl, the user proceeds as follows. Once the device is closed as close as possible to the scalp, the user slides the device along the entire length of the tuft, and at the end of the tuft, the user maintains the device in the closed position and in the closed position two housings ( In order to wrap the tuft around the scalp around 6,7), the device is rotated around itself and then after a few seconds the user unwinds the tuft. This makes it possible to form large sized curls that are smooth and glossy.

  Each static step can last for enough time, seconds, or even 1 minute or even 2 minutes to allow the curl to be properly formed. The stopping length will vary, in particular depending on the temperature of the device and the type of hair being treated.
