Abstract

Provided is a hairstyling apparatus ( 1 ) including a portable treatment unit ( 2 ) provided with two arms ( 3, 4 ) arranged to form a clamp provided with two treatment surfaces ( 5, 6 ) disposed opposite one another and enabling a lock of hair to be clamped therebetween, the portable treatment unit including steam-diffusion means ( 7 ) arranged to diffuse steam from a first ( 5 ) of the two surfaces towards the second ( 6 ) of the two surfaces, one of the arms ( 3, 4 ) including a comb ( 19 ) disposed downstream or upstream of one of the surfaces ( 5, 6 ) of the arm ( 3, 4 ).

First claim

The invention claimed is:

1. Hairstyling apparatus comprising:
a handheld treatment unit powered electrically by an electrical cord and having two arms configured to form a clamp with two treatment surfaces that are flat and form two heating plates and which face each other and come into contact with each other when the clamp is closed, allowing a lock of hair to be clamped, wherein the handheld treatment unit comprises means of diffusing steam configured to diffuse steam from a first of the two treatment surfaces to the second of the two surfaces, and wherein one of the arms has a comb located upstream or downstream of one of the treatment surfaces of said arm,
a means of diffused steam confinement between the two treatment surfaces clamped against each other, the means of diffused steam confinement comprising a single confinement space defined by: (i) a groove located in a second of the two treatment surfaces; and (ii) a furrow located in the first of the two treatment surfaces and which faces the groove, wherein the furrow comprises the means of diffusing steam such that steam is diffused from a bottom surface of the furrow toward the groove when the clamp is closed, and
a steam blocking component positioned on only one arm of the handheld treatment unit, the steam blocking component projecting out from only the first arm that comprises the means of diffusing steam and which is configured to block steam escaping from the means of diffused steam confinement in a direction of a proximal part of the clamp which is configured for manipulating the handheld treatment unit, and
a means of steam generation comprising a steam generation chamber with a heating device, a temperature measurement device, and a reservoir of liquid, wherein the means of steam generation is located in the first arm below the treatment surface,
wherein the furrow and the groove form a cylindrical space when the clamp is in a closed position and a perforated roller is mounted to rotate inside of the cylindrical space.

2. Hairstyling apparatus as in claim 1 , in which the comb is a single comb on the apparatus and is located either upstream or downstream of one of the treatment surfaces.

3. Hairstyling apparatus as in claim 1 , in which the comb is spaced at a distance from an adjacent treatment surface such that the comb is not in contact with said treatment surface.

4. Hairstyling apparatus as in claim 3 , in which the comb is spaced at least 1 mm away from the adjacent treatment surface.

5. Hairstyling apparatus as in claim 1 , in which the comb is fastened to the adjacent treatment surface in such a way that it is in contact with said treatment surface.

6. Hairstyling apparatus as in claim 1 , in which the comb defines a series of teeth extending from a base and wherein the base is located in a plane of the treatment surface.

7. Hairstyling apparatus as in claim 1 , in which each of the arms has a distal portion, and in which the comb is mounted directly on the distal portion of the arm holding the comb.

8. Hairstyling apparatus as in claim 7 , in which the comb is located so that it extends from a lengthwise portion of the distal portion.

9. Hairstyling apparatus as in claim 7 , in which at least a free end of the teeth of the comb is brought to face a length of the distal portion of the arm that is not holding the comb when the apparatus is in closed position.

10. Hairstyling apparatus as in claim 1 , in which the comb is made of at least one of the following materials: thermosetting plastic, metal or aluminum alloy, or thermoplastic.

11. Hairstyling apparatus as in claim 1 , in which the comb has teeth with a pyramidal, conical, or cylindrical shape or a triangular section, or a combination of at least two of these shapes.

12. Hairstyling apparatus as in claim 1 , in which the comb has teeth with a regular gap of 1-8 mm between them.

13. Hairstyling apparatus as in claim 1 , in which the comb has teeth having a height of 3-25 mm.

14. Hairstyling apparatus as in claim 1 , in which the comb is attached permanently to the apparatus.

15. Hairstyling apparatus as in claim 1 , in which the comb is attached to the apparatus such that it can be detached.

16. Hairstyling apparatus as in claim 1 , in which the means of diffusing steam is configured so as to deliver a steam flow rate of 0.5-2 g/min.

17. Hairstyling apparatus as in claim 1 , in which the means of diffusing steam is configured so as to deliver a steam flow rate of 0.05-0.5 g/min.

18. Hairstyling apparatus as in claim 1 , in which the means of steam generation includes the reservoir for liquid to be converted to steam and, in the fluid connection to the steam generation chamber, a water pump designed to activate when the two surfaces are clamped together, to move the liquid from the reservoir to the steam generation chamber.

19. Hairstyling apparatus as in claim 1 , in which the means of steam generation includes the reservoir for liquid to be converted to steam and, in the fluid connection to the steam generation chamber, an air pump designed to activate when the two surfaces are clamped together, to move the liquid from the reservoir to the steam generation chamber.

20. Hairstyling apparatus as in claim 1 , in which the means of steam generation includes the liquid reservoir with a fluid connection to a piece of felt intended to come into contact with the heating device.

21. Hairstyling apparatus as in claim 1 , in which the treatment surfaces have a length (L 1 ) of 80-120 mm and a width (l 1 ) of 20-35 mm.
