Hair Treatment Apparatus With Improved Sealing

Abstract

Hair treatment apparatus having: -first and second arms which are movable with respect to each other and can adopt a spaced-apart configuration, for introduction of a lock of hair between them, and a closed configuration for treatment of the lock of hair, first and second contact surfaces carried respectively by the first and second arms and arranged opposite each other, at least one of the contact surfaces providing heat, -at least one steam outlet carried by one of the arms at a distance from the contact surface situated on the same arm, in order to expose the hairs engaged between the arms to the steam, -at least the first arm having at least one first part supporting the first contact surface and at least one second part distinct from the first part and separated from the latter, -an elastically deformable sealing element having a proximal portion extending at least partially around the first contact surface between the latter and the first support part, and a distal portion extending in contact with the second part, the proximal portion and the distal portion being connected by an intermediate portion extending between the first and second parts and configured to form a screen to the steam.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a hair treatment device, and, more particularly, a device comprising a steam spraying device.STATE OF THE PRIOR ART[0002]It is known to straighten hair with a straightening clamp, such a device also being called a straightener. This clamp allows hair fibers to be smoothed at high temperature without pulling on the hair, unlike brushing. However, in order to obtain a good smooth appearance, it is necessary to make several passes of the clamp, which considerably lengthens the treatment time. Furthermore, the repeated application of the straightening clamp can sometimes cause the degradation of the hair fibers, due to the temperature to which the hair is exposed.[0003]It is known to use steam for the treatment of hair, for example, associated with a treatment with hot plates, the steam being sprayed or diffused on the hair. Such a method can be implemented by a hair treatment device and / or be associated with differe...

AI Technical Summary

Benefits of technology

The technical effects of the patent text are as follows: 1. The contact surface of the device is pivotally mounted on the arm, allowing it to move freely without being hindered by the sealing element. This improves the efficiency of heat treatment and ensures a perfect seal. 2. The device is designed to protect the PTC and NTC thermistors from possible condensate which could damage the device and shorten leak lines.

Problems solved by technology

However, in order to obtain a good smooth appearance, it is necessary to make several passes of the clamp, which considerably lengthens the treatment time.

Furthermore, the repeated application of the straightening clamp can sometimes cause the degradation of the hair fibers, due to the temperature to which the hair is exposed.

This results in different problems.

Indeed, the steam seeking to escape from this restricted volume will partly enter the device, and will condense either in contact with cold areas, or during the cooling of the device, thus risking damaging the device and causing malfunctions.

With these shells being cold, particularly at the start of treatment, the steam that condenses on these external surfaces creates condensation drips or drops, which can annoy the user.
