Description

Hair clipping device equipped with a locking system for locking a water container and a wick in an evaporation position

Technical Field

The present invention relates to the field of hair-cutting devices of the "curler" type for achieving curly hair, and in particular to such hair-cutting devices equipped with a steam-generating system comprising a container of liquid, a core saturated with liquid and a heating element, said core being in contact with said heating element.

Furthermore, such a hairstyling device comprises a mandrel and a tile, these elements being hinged to form a clamp so as to allow the clamping of the lock of hair to wind it around the mandrel and thus to curl it.

Background

Patent applications WO0167915a2 and EP1894488a1 are known in connection with such hair clipping devices comprising the above-mentioned features, which allow the generation of steam during the realisation of the curling of the locks of hair.

A liquid container is disposed at an end of the mandrel, and a liquid-saturated wick is integral with and in communication with the container for saturation with the liquid. The heating element is disposed in the mandrel. A guide mechanism is disposed between the container and the mandrel to allow movement of the container and the wick between a non-working position and a working position in which the wick is in contact with the heating element to generate steam. The steam is generated while manually moving the container and the wick.

During the curling operation of the lock of hair, the user should grip the lock of hair, hold the container against after winding it around the mandrel, so that the wick saturated with liquid remains in contact with the heating element, in order to generate steam continuously. This makes the existing hair cutting devices with this feature less ergonomic.

Furthermore, the user should calculate himself the duration of the treatment of the lock of hair with steam, in order to carry out the treatment of the lock of hair with steam to form a curl, during a suitable duration, which should not be too short, or else the treatment is ineffective, nor too long, or else the hair will be damaged. This requires additional attention from the user during hair cutting. Furthermore, the time of applying the steam varies greatly according to the calculated speed of the user. The user should keep the wick pressed against the heating element for the entire defined duration.

Disclosure of Invention

The object of the present invention is to overcome the above drawbacks.

The main object of the present invention is to avoid that the user should keep the container permanently in the rest position for the generation of steam during the implementation of the hair curling operation.

The invention therefore relates to a hair cutting device for curling hair.

The hairstyling device comprises a spindle and a shoe hinged on the device to form a clamp with the spindle to move the shoe between a disengaged position disengaged from the spindle, which allows the positioning of a lock of hair, and an abutment position against the spindle, which allows the clamping of the lock of hair for the subsequent curling operation.

The hair cutting device further comprises a heating element and an electric mechanism allowing activation of the heating element.

Furthermore, the hair cutting device comprises a liquid container and a wick integral with the container and communicating with the container so as to be saturated with liquid. A guide mechanism is disposed between the container and the mandrel to allow movement of the container and the wick between a non-working position and a working position in which the wick is in contact with the heating element to generate steam.

Furthermore, the hair clipping device comprises a locking/unlocking system configured for ensuring that the container and the core are held in the working position, which avoids that the user should hold the container and the core in the working position during the entire hair curling operation

According to a preferred embodiment of the hair clipping device according to the invention, the locking/unlocking system is configured for ensuring that the container and the core are held in the working position when the tile is in the rest position against the core shaft. This allows to activate the curling and evaporating operations only after carrying out the clamping of the locks of hair. Conversely, when the tile is in a disengaged position disengaged from the mandrel, the locking/unlocking system is configured for allowing disengagement of the container and the core towards an inoperative position. However, some embodiment variants may be provided in which the locking/unlocking system satisfies the above-described retaining and releasing functions, but does not depend on the position of the shoe relative to the mandrel.

According to this preferred embodiment of the hair clipping device, the locking/unlocking system comprises a first locking element provided on the container and a second locking element provided at the distal end of the tile. The locking element is configured to cooperate and ensure that the position of the container relative to the tile is maintained when the tile is in an abutting position against the mandrel and the container and the core are in a working position.

According to this embodiment, the first and second locking elements are configured to snap into each other in order to ensure positional retention of the container relative to the tile. However, variations of the first and second locking elements are contemplated without departing from the scope of the invention.

Preferably, according to this embodiment, the first locking element comprises a U-shaped elastic part equipped with a narrowing and the second locking element comprises a contact arranged on the inner face of the tile. The narrow portion ensures that the resilient part remains engaged on the contact.

According to the haircutting device of the present invention, the locking/unlocking system comprises a return mechanism to return the container and the core towards the inactive position. This ensures an automatic stop of the steam without additional handling of the hairdressing apparatus.

According to the haircutting device of the present invention, said container comprises a filling opening, which allows to reuse the container once it is empty.

According to the hair cutting device of the present invention, said device comprises a detection system for detecting said operative position of said container and of said wick. This allows the start of the vaporisation operation to be detected while curling hair.

In a preferred embodiment of the hair cutting device, the heating element comprises an evaporation plate, the core in the working position being in abutting contact with the evaporation plate. Further, the detection system includes a detection mechanism that detects a drop in temperature of the evaporation plate when the wick saturated with the liquid comes into contact with the evaporation plate.

In the case of such a detection system of the operative position of the container and of the wick, the haircutting apparatus of the invention preferably comprises a computing unit, said detection system being configured for activating said computing unit when said container and said wick are moved from said inoperative position towards said operative position. This allows the user to avoid the need to calculate the holding time of the lock of hair wound around the mandrel during the evaporation operation.

Detailed Description

As shown in fig. 1 and 2, the hair cutting device 1 comprises a main body 2, a spindle 3, a tile 4. The main body 2 is configured for operating the hair cutting device 1 when using the hair cutting device 1. The mandrel 3 is cylindrical and extends the body 2 along a longitudinal axis X. The tile 4 is circular in shape adapted to the shape of the mandrel 3. The proximal end 5 of the tile 4 is fixed together with an operating finger 6, said operating finger 6 being hinged with respect to a distal end 7 of said body 2. Pressing on the rear portion 8 of the operating finger 6 allows moving the tile 4 towards the disengaged position with the mandrel 3, so as to allow the introduction of a lock of hair between the mandrel 3 and the tile 4. When the pressing of the operating finger 6 is stopped, such as shown in fig. 1, the spring 9 arranged between the distal end 7 of the main body 2 and the operating finger 6 allows to move the tile 4 into an abutment position against the mandrel 3, which allows to clamp a lock of hair (not shown) provided between the mandrel 3 and the tile 4.

As shown in fig. 1 to 3, the hair cutting device 1 comprises a container 10, said container 10 comprising an opening 11 at its proximal end 12. This opening 11 allows liquid filling of the container 10 to be carried out. The wick 13 is mounted in a tubular element 14, said tubular element 14 being fixed together with said container 10 at this proximal end 12, said wick 13 being in communication with said opening 11, which allows to saturate the wick 13. The container 10 and the tubular element 14 are mounted in sliding connection on a distal end 15 of the mandrel 3, which allows to translate said element and said core 13 along the longitudinal axis X with respect to the mandrel 3, so as to move the assembly (container 10, tubular element 14 and core 13) from a working position, in which the proximal end 16 of the core 13 abuts against an evaporation plate 17, such as shown in fig. 3, which allows to generate steam, towards a non-working position, in which the proximal end 16 of said core 13 is disengaged from said evaporation plate 17. A spring 18 is arranged in the bottom 19 of said tubular element 14, said spring 18 exerting a pressure against a distal end 20 of the wick 13 so as to hold the wick 13 properly in the working position against said evaporating plate 17. The evaporation plate 17 is in contact with the heating element 21, the heating element 21 being, for example, a thermistor (PTC) having a positive temperature coefficient, which allows the evaporation plate 17 to be heated by thermal conduction. The heating element 21 also allows heating of the mandrel 3.

A locking/unlocking system 22 is arranged on the hairstyling apparatus 1 to maintain the container 10, the tubular element 14 and the core 13 in the operating position described. As shown in fig. 1 to 5, this locking/unlocking system 22 is arranged between a peripheral wall 23 of the container 10 and a distal end 24 of the tile 4. The peripheral wall 23 includes a recess 25 opening onto its proximal end 26, as shown in fig. 4. This recess 25 receives a U-shaped resilient part 27, said resilient part 27 comprising a narrow section 28, such as shown in fig. 4. The elastic part 27 constitutes a first locking element. As shown in fig. 5, the contact 29 extends from the inner face 30 side of the shoe 4 at the distal end portion 24 thereof. The contact 29 constitutes a second locking element configured to be received in the elastic part 27. Said contact 29 is arranged in a recess 25 on the outside of said elastic element 27 when said tile 4 is in the clamping position against the mandrel 3, clamping the lock of hair, and when said container 10 is in the inactive position. Thereafter, when the container 10 is moved into the working position, said elastic element 27 engages on said contact 29 until the narrowing 28 exceeds said contact 29, thus allowing the locking of the elastic element 27 on the contact 29 or vice versa, which ensures the retention of the container 10 in the working position and therefore the retention of the wick 13 saturated with liquid against said evaporation plate 17.

As shown in fig. 3, a return mechanism 31, such as a spring, is arranged between the evaporating plate 17 and the tubular element 14, which spring allows to apply a force to the tubular element 14 in the direction of arrow 32. The locking of the contacts 29 in the elastic element 27 ensures the retention of the position of the container 10 with respect to the tile 4, despite the force exerted by said spring. Conversely, when the tile 4 is moved by the user into a disengaged position disengaged with respect to the mandrel 3, the contact 29 disengages from the elastic element 27, which allows the spring to push the tubular element 14 and the container 10 (and the wick 13) into the working position, stopping the production of steam.

Advantageously, the hairdressing apparatus 1 comprises a detection system which detects the working position of the container 10, the tubular element 14 and the core 13, in which steam is generated. The detection system comprises detection means 33 for detecting a decrease in temperature of the evaporation plate 17, these detection means 33 comprising a temperature sensor, preferably a thermistor with Negative Temperature Coefficient (NTC). The temperature sensor is placed in contact with the inner face 34 of the evaporation plate 17, such as shown in fig. 6. When the proximal end portion 16 of the wick 13 comes into contact with the outer face 35 of the evaporation plate 17, the temperature of the evaporation plate 17 abruptly decreases, and the temperature decrease is detected by the temperature sensor. Said temperature sensor transmits the information of the temperature decrease to the electronic control box 36, as shown in fig. 2, said electronic control box 36 integrating a calculation unit calculating the duration, for example 10 seconds, during which the steam generation and the heating of the mandrel 3 need to be maintained once the lock of hair is wound around said mandrel 3. This duration may be adjusted by the user, for example 5 or 8 or 10 seconds, according to an indication of the duration of exposure to steam, this adjustment being accessible on the user interface provided on the haircare device 1. Once this duration has ended, the calculation unit transmits a message to the electronic control box 36, said electronic control box 36 activating an acoustic signal, for example a beep or even a luminous signal, which prompts the user to disconnect the tile 4 from the spindle 3, in order to disengage the container 10 and the core 13 into the inactive position and thus stop the steam generation, after which the crimped lock is removed.

The container 10 is removable with respect to the distal end 15 of the mandrel, which allows access to the opening 11 on said container 10 in order to carry out the liquid filling of said container 10. For this purpose, the proximal portion 12 of the container 10 is assembled in a removable manner, in particular by snapping, with the bottom 19 of said tubular element 14.

The above description allows understanding the nature of the invention without limiting its scope. Therefore, other variants are conceivable, in particular the implementation of a locking/unlocking system for ensuring the retention of the container 10, the tubular element 14 and the core 13 in the working position. The locking/unlocking system can be designed, for example, between the container 10 or the tubular element 14 and the distal end 15 of the mandrel 3 independently of the position of the tile 4.

Other features may be considered without departing from the scope of the invention. A cover (not shown) may for example be provided, which allows opening the distal end 37 of the container 10 in order to carry out the filling thereof with liquid, without the container 10 having to be detached with respect to the distal end 15 of the mandrel 3.
