Steam Hair-Styling Appliance

Abstract

The invention relates to a steam hair-styling appliance (1) for shaping the hair, comprising: —a first jaw (2) and a second jaw (3), arranged opposite one another and hinged together, a first treatment surface (4) being supported by the first jaw (2) and a second treatment surface being supported by the second jaw (3), the first and second treatment surfaces being configured to grip at least one lock of hair, and —a liquid reservoir, said first and / or second jaw (2, 3) additionally comprising: —a system for vapourising (7) the liquid to form steam, comprising at least one vaporisation chamber (71) which has an inner surface and is in communication via an injection tube (74) with the liquid reservoir, said injection tube (74) having a free end which forms a point for injecting the liquid into the vaporisation chamber (71), and —a system for dispensing (7) the steam from the vaporisation system (7), comprising at least one steam dispensing port (75) directed toward the at least one lock of hair, characterised in that the injection tube (74) comprises an opening extending substantially along the length of said injection tube (74) from the free end which forms the injection point, said opening being a shape that allows the liquid coming from the reservoir to run into the vaporisation chamber (71) in the event of accumulation and deposition of scale at the free end of the injection tube (74).

Description

FIELD OF THE INVENTION[0001]This invention relates to the field of hair-styling appliances, and more specifically to steam-generating hair-styling appliances.PRIOR ART[0002]Hair-styling appliances generally consist of two jaws which are hinged together and opposite each other, each having a treatment surface, at least one of which is heated, the other one enabling a lock of hair to be brought into contact with the heated surface. The hinged jaws generally comprise an area for holding the appliance at the end comprising the hinge in order to be able to manipulate the appliance and in particular to be able to make the jaws pivot to a closed position so as to grip a lock of hair.[0003]In a general operation mode, hair is shaped, for example straightened, by gripping a lock of hair at the roots and then sliding the hair-styling appliance along the length of the lock, from the roots of the hair to the ends.[0004]Variously-shaped treatment surfaces can be arranged on the jaws according to...

AI Technical Summary

Benefits of technology

The technical effect of this patent is to solve the problem of scaling in hair-styling appliances, which can reduce their useful life without making them less compact. It proposes a solution that minimizes the height of the vaporization chamber while keeping the appliance small in size.

Problems solved by technology

However, a rapid increase in the temperature of the liquid, which may contain minerals, in the vaporization chamber may lead to a gradual deposition of scale or limescale on the inside or at one end of the duct and to an eventual clogging thereof.

This phenomenon consequently causes the hair-styling appliance to malfunction and reduces the useful life of the hair-styling appliance.

However, reducing the volume of the vaporization chamber consequently reduces the useful life of the hair-styling appliance because scaling will occur faster, typically at the end of the duct where the liquid is injected into the vaporization chamber.

Unfortunately, such a solution is inconvenient for users and rarely applied in practice, meaning that the appliances remain at risk of scaling and that a technical solution rather than a use solution should be found.

However, such a device is complex and adversely affects the compactness of the hair-styling appliance.
