Definitions

  • the present invention relates to an accessory for curling strands of hair intended to be fixed on a blowing and heating device.
  • Hair curling devices are well known in the state of the art. They generally come in the form of a blowing brush or in the form of a hair dryer with a generally removable curling accessory.
  • the document KR1020190131892 discloses a hair shaping device having an air inlet and air outlet ports.
  • the air flow is guided by a conical-shaped internal deflector allowing uniform distribution of the air flow along the length of the accessory.
  • the document KR20220039371 discloses a sulking accessory for a hair dryer, having a cylindrical body having a series of orifices.
  • the cylindrical body has a larger diameter at the base of the accessory.
  • the internal surface of the cylindrical body includes shoulders which prevent the progression of the air flow.
  • the present invention aims to provide an accessory using less energy than those of the prior art while maintaining the same performance. Thanks to its annular slot, an external air flow acts as a protective air blade around the hair shaping mandrel, and helps limit heat loss from the accessory in contact with the ambient air. The operating temperature of the accessory can therefore be maintained using a power lower than that used by prior art accessories of the same type. Furthermore, thanks to its conical geometry and its internal deflector, the accessory of the present invention allows a studied distribution of the air flow.
  • Another aim of the invention is to offer a hair shaping accessory whose temperature necessary for curling is reached more quickly, thanks to the internal air flow deflected by the specific shape of the deflector located at the inside the hair shaping mandrel.
  • the deflector is of generally frustoconical shape and has on the surface structural obstacles making it possible to deflect an internal air flow radially towards the orifices of the mandrel (shoulders, protuberances, parallel or spiral staircases, etc.).
  • the present invention also offers an accessory making it possible to give more volume to the base of the user's locks of hair thanks to the inverted frustoconical shape of the mandrel.
  • inverted frustoconical shape it is understood that the diameter of the mandrel is smaller on the side of the attachment to the hot air source (proximal side). This results in a tighter curl being formed in the hair wound at the base of the mandrel. Curls are less tight and looser as the strand is wound toward the head of the accessory (distal side), providing more volume at the base of the hair strands.
  • the present invention also discloses a blowing brush comprising a handle on which the accessory is fixed, said brush comprising a blowing and heating device.
  • the blower brush may include a lock cooperating with the locking of the accessory on the brush, making the accessory removable.
  • the present invention discloses a hairdressing accessory 1 for shaping hair, and in particular the formation of curls.
  • An example of this accessory is shown on the figures 1 to 8 .
  • the accessory is shown in combination with a handle 11 comprising a blowing and heating device.
  • the accessory includes an external mandrel 3, on which the user winds his strands of hair to be curled.
  • This mandrel is frustoconical in shape and is connected to a cylindrical connector 2 which can be fixed on a blowing and heating device, in a removable or permanent manner.
  • the “head” of the mandrel 7 refers to the distal end thereof relative to the cylindrical connector, while the “base” of the mandrel 8 refers to the end proximal of it relative to the cylindrical connector.
  • the chuck includes a set of air outlet ports 13 distributed uniformly on its side surface, which allows hot air to be blown across its surface. As illustrated by the Figure 6 , an internal air flow 9 is generated by the heating and blowing device.
  • the mandrel is connected to the cylindrical connector by its smallest diameter, so as to have its inverted frustoconical shape starting from the connector of the accessory.
  • the ratio of the diameter of the distal side (“head”) of the mandrel to the diameter of the proximal side (“base”) of the mandrel is between 1.1 and 2, preferably between 1.3 and 1.7.
  • the mandrel is connected to the cylindrical connector by a star attachment 16, as shown in the figures 1 And 8 .
  • the cylindrical connector 2 of the accessory of the invention comprises an annular slot 6 which allows a second air flow 10, called "external flow" throughout the description of the invention, to be blown around the mandrel.
  • This external flow forms an air blade, like a protective sheath against heat loss around the mandrel, as shown on the figures 2 And 5 .
  • this protective air blade energy savings can be made because the power used is less for an identical air outlet temperature.
  • the annular slot is interrupted occasionally by the star-shaped fixing lugs 16 of the mandrel on the cylindrical connector.
  • the annular slot has a height of between 0.5 and 2 mm, preferably between 0.7 and 1.3 mm.
  • This frustoconical deflector comprises a surface structure with obstacles 5 making it possible to axially deflect the internal air flow towards the outside of the accessory, through the air outlet orifices provided on the surface of the mandrel.
  • the surface structure of the frustoconical deflector can be of any type of shape making it possible to create an obstacle deflecting the air little by little, and more homogeneously, through the mandrel.
  • the structure can for example be in the form of a spiral, with protuberances placed judiciously on the deflector ( Figure 12 ), in the form of a specific roughness, in the form of shoulders ( figures 6 and 7 ), etc.
  • the deflector of frustoconical shape comprises as air deflection obstacles on the surface shoulders 5 generated by an “assembly of cylinders 14 with interconnected increasing diameters”. These shoulders, similar to stair steps as illustrated on the figures 6 and 7 , obstruct the flow of air which is blown in a longitudinal direction inside the mandrel. In this way, the internal flow abuts against each shoulder and then exits radially from the mandrel via the air outlet orifices. The internal flow is then divided into a set of sub-flows, distributed uniformly over the entire length of the mandrel.
  • the shoulders are preferably perpendicular to the longitudinal axis of the deflector.
  • the deflector preferably comprises between 8 and 12 shoulders. The distance between the shoulders is preferably between 8 and 14 mm.
  • the diameters of the mandrel and the deflector are smaller at their base than at their head.
  • the conicity of the deflector is greater than that of the mandrel, with a ratio of the conicity of the deflector to the conicity of the mandrel of between 1.1 and 1.5, preferably between 1.2 and 1.3.
  • the slope of the truncated cone of the mandrel is between 1 and 5° and preferably between 2 and 3°, while that of the deflector is between 2 and 5°, preferably between 2.5 and 4° relative to the axis horizontal.
  • the combination of the two air flows, internal and external, allows on the one hand a rapid rise in temperature of the chuck and on the other hand a more uniform distribution of the flow over the entire length of the accessory.
  • the graph of the Figure 10 compares the evolution of the temperatures of the chuck of an example of accessory of the invention ( figures 1-9 ) with those of a similar accessory of the prior art ( Figure 11 ), for the same heating power. Measurements are taken using temperature sensors positioned on the surface of each chuck, at the base, center and head thereof.
  • the accessory of the prior art is illustrated by the Figure 11 .
  • This does not include an internal frustoconical deflector or a slot generating a protective air blade.
  • the mandrel is frustoconical in shape with a larger diameter on the proximal side than on the distal side, unlike the mandrel of the present invention.
  • the graph of the Figure 10 clearly illustrates a higher temperature for the accessory of the present invention at each point of comparison, for identical heating power and air flow. Furthermore, it also results in the accessory of the present invention being brought to a higher temperature more quickly.
  • the mandrel of the present invention is already at 89 degrees on the proximal side (47 degrees for the prior art mandrel), 93 degrees at its center (73 degrees for the prior art mandrel) and 38 degrees degrees on the distal side (26 degrees for the mandrel of the prior art).
  • the chuck of the accessory is generally made of conductive metal, preferably aluminum or copper, and preferably has a ceramic layer for more uniform heat distribution.
  • the mandrel comprises at its base an opening 15 allowing the passage of the internal hot air flow 9 (see figure 8 ).
  • the internal flow generated inside the mandrel is blown by the blowing device through this opening surface 15.
  • the ratio of the opening surface 15 feeding the deflector to the surface of the annular slot is between 2 and 5, and preferably between 2.5 and 3.5.
  • the open surface of the annular slot is preferably between 60 and 100 mm 2 , while the opening surface which feeds the deflector is preferably between 200 and 300 mm 2 .
  • the total surface area of all the air outlet orifices 13 distributed over the mandrel is preferably between 1200 mm 2 and 2000 mm 2 , preferably between 1500 mm 2 and 1700 mm 2 .
  • the ratio of the total surface area of all the air outlet orifices to the surface area of the annular slot is preferably between 15 and 25, preferably between 18 and 22.
  • the present invention is not limited to a hairdressing accessory, but can also extend to any type of blowing brush comprising the accessory as described above.
  • the accessory can be removably attached to the blower brush which then acts as a handle (see Figure 9 ).
  • the accessory can therefore be part of a set of various accessories capable of being attached to the same blowing brush to provide different shaping of the hair.
  • the accessory comprises locks 12 cooperating with locks provided on the brush (not shown), allowing reversible locking of the accessory on the brush.
  • the accessory can also be permanently attached to a blower brush, such as a fixed tip.
