Definitions

  • the present invention relates to a diffuser that can be used with hair dryers.
  • the air flow emanating from a hair dryer is normally strong and not focused, so that wet hair can be dried quickly and effectively.
  • Some hair dryers offer the possibility of switching the speed of the air flow between fast and slow and the temperature of the air flow from cool to warm to hot. Not all hairstyles can be dried satisfactorily with this conventional hair dryer. Therefore devices such as nozzles have been created that can be placed on the air outlet of a hair dryer.
  • Another additional device is the diffuser, with which the air speed of the emerging air flow can be reduced.
  • a diffuser generally comprises a cup-like outer shell, the bottom of which has an opening which leads to a tubular adapter and facilitates attachment to the air outlet opening of a hair dryer.
  • the open end of the cup-like outer shell is surrounded by a further cup-like inner shell, which has a smaller radius than that of the outer shell, so that a closed interior is formed between the opposing palms of the inner and outer shells .
  • a multiplicity of, in particular, hollow and, in particular, ends which are open at the end extend from the outer surface of the inner shell, so that when in use the air from the hair dryer is blown out through the ends of the diffuser which are open at the end. ,;
  • the effect of a diffuser is to distribute the air flow from the air outlet opening of a hair dryer through a plurality of openings with a relatively small diameter. This causes both a reduction in speed and counter if necessary, cooling the air flow. This leads to much more gentle drying than would be the case with a hair dryer without a diffuser attached.
  • the air that blows out of the openings in the ends of the pins does not swirl the hair. This makes the diffuser particularly suitable for drying naturally curled and permanently waved and wavy hair.
  • Such a diffuser is known, for example, from EP 0439781 AI by the applicant.
  • This diffuser consists of a diffuser bell that widens outward in the shape of a funnel and a diffuser screen. Numerous spacer fingers are provided on the outside of the diffuser screen, which have outlet openings at the ends, as a result of which the escaping air can also reach the area of the hair roots and a better flow through the hair is achieved.
  • Conventional diffusers are not particularly well suited for handling curls or waves, especially in the case of naturally straight hair.
  • the present invention has for its object to provide a diffuser with which, in addition to drying, shaping of the hair, in particular the formation of curls or waves, is easily possible.
  • a diffuser for a hair dryer which comprises a diffuser body which can be fixed to an air outlet opening of the hair dryer and has a plurality of hair detection elements which extend away from the diffuser body, at least one of the Hair detection elements is movably arranged on the diffuser body.
  • the diffuser according to the present invention is used in a similar manner to the conventional diffuser. If the hair comes into the area of the hair detection elements while the diffuser is in use, these dip into the hair, so that the hair is arranged in separate strands between the hair detection elements.
  • the subsequent user-defined effective movement of at least one hair detection element, the respective strands of hair lying between the movable hair detection element and the adjacent immovable hair detection elements are deformed and exposed in the form of a curl, wave or other bend to the air stream emerging from the diffuser.
  • the strands of hair caught between the hair detection elements and deformed due to the displacement of at least one hair detection element are dried by means of the diffuser according to the invention and brought into a natural-looking curly or wavy shape.
  • the hair-capturing elements are advantageously moved relative to one another, as a result of which the strands of hair that come between the hair-capturing elements lie in several waves or curls between them. When the hair dries, a naturally acting wave or curl can then be formed in the hair.
  • a first group of hair detection elements is fixed on the diffuser body and a second group of hair detection elements is movable relative to the first group of hair detection elements.
  • This allows a larger range of hair, i.e. shape several strands of hair at the same time. If one group of hair detection elements is moved relative to the other group during the drying process, individual sections of the strands of hair are held in their position by the fixed hair detection elements, while they are placed in waves or curls accordingly and in this position by means of the hair detection elements which are movable for this purpose be dried. Depending on the size of the deflection, larger or smaller curls and waves are achieved.
  • all of the hair detection elements can be moved relative to one another, as a result of which the required size of the deflection of the hair detection elements is reduced relative to one another, and thus better handling of the diffuser is made possible.
  • the circular movement of at least one group of hair detection elements with respect to a central axis of the diffuser ensures a simple mechanical structure of the diffuser with favorable handling and very good hair styling results.
  • the diffuser body advantageously comprises an outer shell and an inner shell which is rotatably supported and secured within the outer shell. This gives a diffuser body a construction which is inexpensive to construct and inexpensive to manufacture.
  • the inner shell is connected to the outer shell by a middle piece, the inner shell being rotatable about the central axis of the diffuser and the middle piece being fastened to the outer shell by openings in the inner shell, in a structurally simple manner and secured the inner shell against falling out.
  • the outer shell, the inner shell and the center piece have an essentially circular circumferential line
  • the openings provided in the inner shell for fastening are designed as arc-shaped elongated slots and the rotation of the inner shell is limited by the dimensions of the openings.
  • the hair detection elements are preferably arranged in a ring on the diffuser body.
  • the hair detection elements arranged in a ring on this shell are displaced in relation to the hair detection elements arranged in a ring on the middle piece, as a result of which the simultaneous shaping of several strands of hair or a larger hair area takes place.
  • individual groups of hair detection elements can be moved in a circle around different axes of rotation assigned to each group.
  • smaller areas of the hair can each be independent shaped or curled from one another and special effects with regard to the hairstyle are generated.
  • the inner shell has depressions with openings in which disks with hair detection elements provided thereon are rotatably arranged.
  • This design of the inner shell serves to position the panes.
  • the arrangement of additional disks enables a more individual hair styling, the shape and density of the waves or curls of individual hair areas being able to be varied within wide limits by the number of hair detection elements arranged on the disks.
  • the disks preferably have an axis with a gearwheel, the axis being guided by cylinder connections which enclose the openings. With these cylinder ports, the disks are axially secured on the one hand, and the gear wheel, on the other hand, provides the conditions for driving the disks.
  • a rotating device with an angular, for example T-shaped or L-shaped cross section is arranged between an outer region of the shells, one leg being directed radially inwards and having internal teeth at its end which is arranged meshing with the gear inside the diffuser. If the user actuates this easy-to-use rotating device, the movement is transmitted to the gearwheel and from there to the disks, thereby driving them and thereby moving the hair detection elements relative to one another.
  • the disks Due to the fact that the disks have an edge with internal toothing through which the further disks provided with a toothed outer edge can be driven, an individual drive of the individual disks is achieved in a structurally simple manner.
  • some of the disks can be formed without a toothed outer edge, so that they remain unchanged in their position, while the disks with a toothed outer edge are driven by the inner toothing.
  • individual groups of hair detection elements can be moved in the radial direction with respect to the central axis of the diffuser.
  • a favorable possibility of individual shaping for the hair is achieved, which is completely different from the circular movements of the hair detection elements.
  • the diffuser body comprises an outer shell and an inner shell, and a disc with curved curved recesses which rise or fall towards the edge of the disc and an edge designed as an actuating ring is rotatably arranged between the shells. If the user rotates the actuating ring, the hair detection elements are moved in the radial direction via the curved recesses.
  • the inner shell has guides with openings in the radial direction, in which strips with hair detection elements are accommodated, rows of hair detection elements being fixed between the strips, individual areas of the hair are held in position by the fixedly arranged hair detection elements while other areas are brought into a different position with respect to the fixedly arranged hair detection elements by the hair detection elements arranged on the strips, as a result of which inevitably curling or curling of the hair occurs.
  • the guides serve to secure the slats laterally against twisting.
  • pins provided on the strips engage in the curved recesses and the strips can be displaced radially by means of the actuating ring. This structurally simple curve control enables the hair detection elements to move smoothly and, moreover, ensures that the strips are guided precisely during their radial movement.
  • individual groups of hair detection elements can be moved linearly and in opposite directions to one another, which results in other forms of waves or curls. This reduces the required size of the linear deflection, which at the same time achieves better handling of the diffuser.
  • the diffuser body advantageously has a substantially rectangular outer circumference, the inner shell being formed by individual strips equipped with hair detection elements and lateral guides. As a result, larger areas of hair, which are determined by the respective strip width, are shifted against one another and dried in this opposite position. The lateral displacement of the strips relative to one another determines the size of the waves or curls.
  • the strips are designed as toothed racks and are guided on an underside of the inner shell, the strips interposing with one another, but meshing at least with one gear, the linear movement of the strips and their displacement relative to one another is achieved in a simple manner.
  • the strips can be moved via an adjusting means arranged on the outer shell, which is coupled to one of the strips. If this adjusting means is moved linearly, this movement is transmitted to the bar and from there by means of a toothed rack via a toothed wheel to the other bars, as a result of which they move in opposite directions to the driven bar.
  • Another possibility of the drive consists in designing the adjusting means as a wheel and with one of the gearwheels arranged between the strips to couple. When the adjustment means is rotated, the gearwheel is then rotated and, due to the toothed rack design, the strips are simultaneously driven in opposite directions to one another.
  • the hair detection elements are advantageously designed as knobs, fingers, prongs, pins or the like.
  • the hair detection elements can take on special shapes depending on the individual wishes or requirements.
  • the hair-capturing elements are hollow on the inside and have at least one opening, which is preferably arranged on the side, at the upper end, the escaping air can reach the area of the hairline in order to loosen the hair more easily and to dry it from the inside.
  • the diffuser is connected in one piece to the hair dryer, thereby creating an independent new hair care device for special purposes.
