BRIEF SUMMARY
BACKGROUND OF INVENTION
A mouthpiece to curl and dry hairs is the subject matter of the present invention and more particularly a mouthpiece intended to be employed by combining it with a round brush such as those used by professional hairdressers, said axis being the longitudinal axis of a curling hair brush 6 employed by a hairdresser in conjunction with the hair dryer.
Numerous shapes for hairdryer mouthpieces are on the market. All these mouthpieces, nevertheless, have, in common, the fact that the flow of hot air produced by the hairdryer is directed in a more or less concentrated flow towards the roots of the hair, i.e. the scalp. Now, this flow of hot, dry air on the scalp has the effect of stimulating the glands and thus causing heavy secretion. Furthermore, the air flows towards the hair in the opposite direction of the cortex which is prejudicial to the hair. Besides, when the hairdresser is working with a round brush before the hairdryer, around which brush he rolls a lock of hair, he must be careful to direct the hairdryer so that the flow of air does not snatch the hair from the brush and, in order to do so, he must often hold the hairdryer in a difficult position.
The purpose of the present invention is to overcome these inconveniences and, in a positive manner, make sure that the flow of air is directed in a favourable direction.
With this in mind, the mouthpiece to curl and dry hairs according to the invention is distinguished by the fact that the surface of the extention is comprised by a round deflector (4) extended in a continous manner from the exit of the nozzle (3) till the front extremity is relative to the direction of the air flow (F) around an axis represented by a brush (6), hold by the user's hand, which is located ahead of the nozzle, the opening angle of the round deflector is of approximately 180.degree., the circular cylindrical surface is directed to the air flow (F).
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
The deflector has several favourable effects, simultaneously: it protects the scalp from the hot-air flow; it directs the flow of hot air in such a way that it flows from the roots towards the tips of the hair; it generates a vortex effect enhancing the rolling up of hair about a round brush placed before the nozzle.
The attached drawing shows as an example the use of the invention.
BRIEF DESCRIPTION OF DRAWING FIGURES
FIG. (1) is a hairdryer supplied with a mouthpiece to curl and dry hairs according to the invention and shows its use with a round brush.
FIG. (2) is a detailed, perspective view of the mouthpiece.
The removable mouthpiece (1) is slipped into the end of a hairdryer (2), of any sort. The mouthpiece 1 is fitted with a nozzle (3) extended along the under side by a deflector (4) comprised of a cylindrical surface extending approximately 180.degree. about an axis located 2 or 3 cms ahead of the nozzle (3). The mouthpiece may be made of injected synthetic material or of metal. In the example shown, the nozzle (3) has a relatively narrow rectangular opening concentrating the flow of hot air into the area limited by the deflector. The nozzle opening could nevertheless be of another shape, for instance, circular.
When the hairdryer is used with a round brush to shape the curls, the lock of hair (5) is rolled up in the usual way around the brush (6) and, simultaneously, the hairdryer (2) is positioned hear the head so that the extremity of the deflector (4) can go under the brush. The hairdryer (2) is held in the normal, convenient way, its axis being directed perceptibly perpendicularly to the head. You can see that in this position the scalp is protected from the flow of hot air (F) by the deflector (4). Moreover, this deflector gives the flow of air (F) a vortex effect round the brush, which enhances the rolling up and holds it in place. It is thus easy to obtain a perfect curl.
The invention is, naturally enough, not limited to shape of execution shown, but extends to any variant producing a cortex air effect.
