Definitions

• the present invention relates to a hairdressing apparatus using steam, intended for shaping by contact with the hair, in particular the smoothing, wrapping or embossing of a person's hair.
• Two types of hairdressing apparatus are traditionally known for smoothing or curling or embossing, the surfaces of which pinch the hair are flat or curved or uneven and are heated or heated.
• the devices of the type pliers to smooth or loop or emboss usually comprise two pivoting jaws each having an end supporting a treatment surface, at least one of the treatment surfaces being heated, the other being provided to bring the hair in contact with the first, in particular by passing from an opening position of the jaws allowing the insertion of the hair to a closed position for their contact with the heating part.
• the other end of the jaws form two half-handles acting as a gripping area and to move from the open position to the closing position.
• the passage is done manually by pressing the two half-handles articulated from the device towards each other to bring the treatment surfaces in contact with the hair.
• Smoothing a lock of hair is done by moving the device along the wick, from the root to the tip.
• the wrap of a lock of hair is made by at least partially winding the wick around the treatment surface (s) and applying heat to fix the loop mainly in static.
• US3702616 discloses a hairdressing apparatus with an internal reservoir and a means vaporization of the fluid contained in the reservoir.
• This reservoir can be associated with a pump controlled by manual actuation of the user who thus chooses its application of steam. Thus with manual control, it takes a few seconds for the pump to start, move the amount of fluid and vaporize it.
• WO2004002262 discloses a steam curling iron with an internal reservoir for storing the water to be sprayed, this reservoir is in contact with a flat porous element bringing the liquid of the reservoir into contact with the heating block to be sprayed and with a vapor path to outlet ports at the iron treatment plate.
• the reservoir is in the apparatus and the porous element aims to obtain a constant flow of steam.
• this apparatus has the disadvantage that the steam flow can not be stopped, unless there is no more liquid in the tank, or regulated properly.
• no hairdressing apparatus producing steam has compact means, robust, automatic, simple design, secure, able to operate in hot environments, can ensure a continuous or even constant flow of steam, and having a very high steam response fast.
• the object of the present invention is to remedy at least in part the aforementioned drawbacks and to provide a shaping device by contact with the hair using steam and having compact means, automatic, and can ensure a flow of steam also as continuous and responsive as possible.
• Another object of the invention is a steam hair shaping apparatus capable of controlling and reliably at least one of the operating parameters of the steam.
• Another object of the invention is to provide a shaping device for hair shaping that can ensure a constant flow of steam.
• Another object of the invention is to provide a hair-forming steam apparatus which is solid, robust in operation and ensures good aging with respect to mechanical deformations for example.
• Another object of the invention is to provide a hair-forming steam apparatus that is effective and / or rapid in operation.
• Another object of the invention is to provide a device for shaping by contact with the hair, steam and / or fluid distribution, and which is sealed in operation.

• the control unit at the end of countdown D1 without receiving the actuating signal, has means for automatically controlling the flow control means for a predetermined momentary duration d1 at least five times shorter than the predetermined counting time D1. This ratio makes it possible to avoid overloading the means for adjusting the fluid flow rate.
• the control unit has means for automatically controlling the flow control means on a first momentary duration "D1" at least five times shorter than the duration of the first count D1, and has means to then count down a second predetermined duration D2 at the end of which without receiving the actuating signal, the flow control means are controlled automatically on a second momentary duration d2 identical to the first momentary duration d1. Indeed if after the second count -certes shorter than the first count- the pump or equivalent was not solicited by the operation, the probabilities that the user does not use the device are high, and the pump is activated after a shorter wait.
• the compensation means temporally control the adjustment means as a function of: at least the heating temperature setpoint of the vaporization chamber, and / or at least the interior volume of the end of the vaporization chamber; pipeline for transporting the fluid arranged in the vaporization chamber.

• the compensation means of the control unit make it possible to control the fluid flow control means for a complete duration of between 2 and 4 minutes, preferably 3 minutes, as long as the control unit receives no actuation signal from the flow control means. After this elapsed time without receiving an actuation signal, the device exits the compensation cycle.
• the control unit receives from the actuating means an actuating signal of the flow control means, then it controls the resetting of the counter at the end of the actuation . And the cycle starts again from the beginning.

• the use of a peristaltic pump makes it possible to obtain a compact, watertight, effective starting device, of high endurance, for a rather low flow rate, a constant possible flow rate, insensitive to the positioning in the space according to the gestures of the user, simple, and providing great security.
• the peristaltic pump 6 is a pump used for a liquid contained in a flexible tube, it is driven by a clamping system pressing the tube inside the pump 6.
• the peristaltic pump is sealed and the only element in contact with the fluid is the flexible tube. The risks of leakage are thus limited, and the volume of liquid displaced is proportional to the speed of rotation of the pump.
• This pump is particularly suitable for dosing, thanks to its flexibility of use and its high accuracy.
• the pump provides a relatively continuous flow, and even relatively constant, of the order of 1 to 5 mL / min, or between 3 and 4 preferably equal to 3.5 mL / min.
• the pump is actuated by a motor preferably DC.

• the first chamber 7' has a substantially parallelepipedal volume having a section selected from one of the following sections: rectangular section, trapezoidal as illustrated in FIG. distribution 16 are arranged laterally to the vaporization means 7 and preferentially extend over substantially the entire length of the vaporization means 7.
• the chambers are made of aluminum.
• the complete vaporization chamber has an approximate dimension of 83 mm in length, a width of 18mm and a height of 5mm
• the first chamber 7 ' has a water inlet in the form of a water supply pipe 15 whose orifice is arranged at the first quarter of the length of the first chamber or alternatively at the center of the first chamber (not shown) and substantially in the middle of its width.
• the inner diameter of the inlet pipe measures 3mm and its length in the chamber is 17mm.
• the user grasps the device and applies it to pinch the lock of hair to be treated.
• the microcontroller 13 leaves the counter at 0. As soon as the pump is no longer activated (manually or by detecting closure of the straightener) then the microcontroller 13 controls the first incrementation of the counter. As soon as the counter reaches the first predetermined time of the first zero slot (28 here) then it sends the CPU a momentary actuation signal to the pump (over 2 seconds here). And this count starts again as long as the pump is not operated manually or by detecting closure of the straightener. The second incrementation then begins on a second predetermined duration of 10 seconds.
• the unit exits the compensation cycle. If the pump is not reactivated then the product shutdown is controlled. If the pump is reactivated, then the flow chart restarts at the beginning. This allows, in duration of non-activation of the pump (neither manually nor by detecting the closed position of the straightener) to supply momentarily and regularly the inlet pipe 15 of the chamber. Thus the chamber has an effective vaporization by its inlet pipe entering the interior while having a high reactivity to the actuation. No compromise between responsiveness and efficiency is done here.
• the apparatus comprises at least one component playing on at least one operating parameter of the apparatus and which can be controlled by the CPU on receipt of the signal representing the opening or closing of the hairdressing apparatus .
