    CROSS REFERENCE ON RELATED REQUEST
    [001] This International Patent Application relates to and claims priority from United States Provisional Patent Application No. 61/69 3,136 entitled "Concentrator", filed on August 24, 2012, and in the United States Patent Application No. 12/673,706 entitled “Concentrator” filed on November 9, 2012, the contents of which are incorporated herein in their entirety by way of reference. BACKGROUND
    [002] Hairdrying devices distribute a stream of hot air to dry and style the hair into a desired style. A diffuser is generally used to disperse the air flow from a hair drying device, thereby creating curls, body and texture in hair without waving. Under certain circumstances, it is desirable to modify the design of a hair drying or styling device or its accessories in order to achieve a particular hair style.
    [003] Consumers often pay a very high price for their hair to be professionally dried in order to achieve a beauty salon look. Hairdressers work meticulously by drying and styling specific parts of hair at the same time. When drying the hair, the hairdresser uses a brush, selects a small section of hair, and repeatedly applies heat to the hair. By concentrating the heat on a particular section and simultaneously pulling the brush in a desired direction, the drying process shapes the hair, creating volume and shine at the same time. For example, when heated air from the dryer is applied, and the brush is pulled down towards the ends of the hair, a smooth finish is created.
    Modifications to hair drying devices to improve performance can be found in US Patent Nos. 3,563,250, 5,956,863, 3,939,850, 6,199,295, and 5,316,025. However, each of these modifications suffers from one or more disadvantages such as complexity, high cost, and limited effectiveness. For example, most hair dryer modifications have strange settings, making the drying process even more challenging for the user and can be tiring and frustrating.
    [005] Typically, hair dryers have a tubular body that houses a fan that defines an air inlet and an air outlet. An electric motor is provided to control an internal fan that draws in air from the environment into the air intake. Air is usually forced through a heating element towards the air outlet. Heated air flows through the air outlet and out of the body around the air outlet. The circular cross section dries and smooths the hair surface, while the hair underneath remains wet for a long period of time.
    [006] A conventional hair drying device without an attachment attached has a circular section flow pattern. Accessories can be fitted to the body around the hair dryer's air outlet. Heated air flows through the body and out of the air outlet and through the accessory that changes the air flow pattern. A variety of accessories are known to alter the airflow pattern of the hair dryer, such as those described in US Patent Nos. D426674, 4538362, 71521610, D440354, and French Patent No. 2888095. they suffer from one or more of the disadvantages of low efficiency, and inability to create volume and style hair with a smooth finish.
    [007] For the above reasons, there is a need towards a hair treatment device that overcomes the disadvantages of the above devices. SUMMARY
    [008] A hair treatment device with the features of the present invention meets the needs identified above. An exemplary device has a body and a fan supported by the body from which air is blown. A concentrator connected separately to the fan, or integral with the fan, comprises at least one gas flow conduit in gas flow communication with the fan. A nozzle is in gas flow communication with a distal portion of the conduit and is oriented so as to blow air from the distal portion of the first conduit back into the body.
    [009] Advantageously, the gas flow conduit has a longitudinal axis and the nozzle directs air from the distal portion of the gas flow conduit towards the body at an angle greater than one hundred degrees relative to the longitudinal axis to direct the air on the outer surface of the hair.
    [010] The body may comprise two such gas flow conduits, each having a nozzle in gas flow communication with the respective conduit, both nozzles being oriented to blow air from the distal portion of the respective conduit towards the body. Preferably, the longitudinal axes of the ducts are parallel to each other. The diameter of the nozzle outlets can be smaller than the diameter of the gas flow conduits for air concentration to increase its velocity.
    [011] The hair treatment device can optionally have a bar, which optionally has projecting bristles, positioned between the two gas flow conduits. The projecting bristle bar is positioned on the device so that the air exiting the nozzles intercepts the bristle portion of the device. The bristle portion can be used to wrap a user's hair. The bar can be permanently attached to the device or be insertable so that the user can remove the bar. Removable functionality allows bars of different sizes or bristle properties to be inserted into the hair care device. For example, the bristle portion may have more of a brush-like configuration or a comb-like configuration. The bar can be of solid construction so that no air flows through the bar, or the interior of the bar can be hollow to create an additional air flow path through the device. When the bar has a hollow configuration, it can optionally have openings so that air exits from both the bristle portion of the device as well as the nozzles.
    [012] The body may be cylindrical in shape, with the gas conduit portion positioned at one end of the body and a grip section provided to fit a user's hand at the other end. Alternatively, when there is a cylindrical shaped body, the device may have a gripping section positioned essentially perpendicular to that body, and a switch can be positioned on that gripping section.
    [013] In using the device, a user grips the hair treatment device and activates the fan whereby air is forced through an optional heating installation, and subsequently through one or more gas flow conduits and the one or more nozzles. The mouthpiece directs air to the body. The user places the hair in a location where the directed air, together with the bristle portion envelops the hair, thus drying and styling the hair.
    [014] When the concentrator is not integral with a fan, it can be used by (a) placing the inlet of the concentrator over the outlet of a hair appliance, b) placing the hair in a location where air is blown from the mouthpiece; and c) activating the hair appliance to blow heated air through the concentrator, before or after step (b).

    [024] The present invention is directed to a hair treatment device capable of drying and styling hair, and a method for doing so. In the description which follows, numerous specific details are set forth to provide a more detailed description of embodiments of the invention. It is evident, however, to one skilled in the art, that the embodiments of the present invention can be practiced without such specific details. In other cases, well-known features have not been described in detail so as not to make the invention less clear.
    [025] Referring to Figures 1A and 2A, a hair treatment device 20 comprises a body 22 having a main body section 22A and a concentrator section 22B and an internal cavity 24. A fan 26 supported by the body 22 is inside cavity 24. The concentrator section 22B comprises at least one and preferably two gas flow conduits 28, each having a proximal section 30 in gas flow communication with the ventilator 26 and a distal section 32 with at least a nozzle 34 in gas flow communication with its respective conduit 28. The nozzles 34 are oriented to direct air from the distal section 32 of the conduit 28 to the body 22. A switch 36 may be located in the main body section 22A or at another suitable location for controlling the heat and/or operating speeds of the hair treatment device 20. The exterior of the main body section 22A may be provided with gripping projections 38 to facilitate the use of the device. sitivo 20. An optional bar 40, optionally with projecting bristles 42, may be located on device 20 between conduits 28 to wrap the user's hair.
    [026] The gas conduit portion 28 is located at an axial end of the tubular body 22 which directs the forced air air flow to the desired pattern, while the gripping projections 38 for the user are located at the other axial end of the body 22.
    [027] The device 20 as shown in FIG. 1 illustrates a preferred embodiment with two parallel gas ducts 28, in a horseshoe-like configuration. They each have a parallel longitudinal axis. The two parallel gas flow conduits 28 work together to direct air towards a common point. By having more than one gas duct 28, the air exiting the nozzles 34 is concentrated at the common point. The distance between the two gas conduits 28 can be from about 2.54 cm (1 inch) to about 15.24 cm (6 inches).
    [028] Preferably, the nozzles 34 are oriented so that air is directed by the nozzles 34 towards the body 22 at an angle greater than one hundred degrees with respect to the longitudinal axis of the conduits 28. In a preferred embodiment, the diameters The interior of the nozzles 34 is smaller than the interior diameter of the gas flow conduits 28. The openings of the nozzle 34 may optionally be covered with a screen or mesh to prevent hair from being sucked into the openings.
    [029] The bar 40 may be located where the air exiting the nozzles 34 intersects the bristles 42. The bar 40 with projecting bristles 42 may be permanently attached to the body 22 of the device 20 or may be removable to allow bars 40 with different sizes and different bristle properties are used. The cross section of bar 40 can be square, rectangular, circular, or any shape that suits the configuration of the device. By having 40 bars with different sizes or bristle properties, the resulting hairstyle capability can be changed. The bristles 42 can be a type of hairbrush bristles including wild boar, nylon or other plastic bristles, or a combination of bristle types such as wild boar and plastic bristles. Boar and plastic bristles can have varying stiffness for different brushing applications, such as soft bristles for fine or delicate hair, and stiff bristles for thick or thick hair. Nylon or plastic bristles can have rounded or spherical ends to avoid irritating the scalp, and wild boar and plastic or nylon bristles can be combined into a brush for still other hair brushing applications. Other options can also be used for projections, such as tourmaline, silicone or silicone coated bristles, or other bristle coatings that reduce frizz and improve hair straightening and detangling. The bar 40 with projecting bristles 42 can be of solid construction or it can have a hollow internal cavity. Optionally, where bar 40 has a hollow internal cavity, bar 40 may have openings that allow air to exit bar 40 and flow through bristles 42.
    [030] Figure 1B illustrates another version of a hair care device that has an alternative configuration of body 22, which can accommodate an oversized bar 40 with projecting bristles 42. In this version, bar 40 with projecting bristles 42 is hollow, creating a flow path so that air forced from blower 26 enters distal gas flow conduit 28 and nozzle 34.
    [031] As shown in Figures 2A and 2B, ambient air is drawn into the internal cavity 24 of the main body section 22A in a gas communication path therethrough so that air is forced under pressure through of the body 22 of the device 20 by the fan 26.
    [032] As is typical with hair dryers, the main body section 22A houses the fan 26 and its components. The fan 26 generally comprises a motor for rotating a fan located within the body 22 that is electrically connected to a power source, such as AC power through a power cord 46. A heater is typically on the body 22 for heating the air flow moving therethrough. According to this version, a heated fan 50 is used, which includes a heater installation 52 and a fan installation 54. In an exemplary version, the heater installation 52 functions as a resistor to which current is fed through the cable. feeding 46 or by other means. Other examples of a hair styling tool with a heating element can be seen in US Patent Nos. 7,631,646; and 7,481,228, the full disclosure of which is incorporated herein by reference.
    [033] Referring now to Figure 3, instead of having a concentrator 60 integral with a hair blower 26, a concentrator 60 may be a self-contained unit which can be detachably connected to a hair appliance 70 having a blower 26 In a preferred embodiment, hair apparatus 70 is a hair dryer. Generally, a hair dryer air outlet 62 has a tubular or circular opening, and likewise an inlet portion 64 of the concentrator 60 is tubular and circular in cross section. The concentrator 60 can be placed in the hair apparatus 70 before or after the hair apparatus 70 is activated.
    [034] In this version, the body 22 of the concentrator 60 has a tapered intermediate section 66 and a discharge end 68, the tapered intermediate section 66 being between the inlet portion 64 and the discharge end 68 defining a gas flow path through them. In a preferred embodiment, the body 22 of the concentrator 60 defines two parallel gas conduits 28 in a horseshoe-like configuration. The body 22 can be made from a variety of materials conventionally used for hair appliances 70, hair dryers and hair dryer accessories, such as metal or plastic, notably polypropylene or combinations thereof.
    [035] As can be seen in Figure 4, the air flowing through the internal cavity 24 of the body 22 is diverted into the gas ducts 28, which are in gas flow communication with the body 22. The air then passes through the gas ducts 28 and subsequently through the nozzles 34 as shown in Figure 3 towards a common point. A bar 40 with projecting bristles 42 is located at the common point.
    [036] In Figure 5, a bottom plan view of the concentrator 60 illustrates the internal cavity 24 of the concentrator 60. Air is directed from the fan 26 into the gas flow conduits 28 and through the nozzles 34, as shown in Figure 3, thus concentrating the air. When the inside diameter of the nozzles 34 is smaller than the inside diameter of the gas flow conduits 28 the air is further concentrated before exiting the nozzles 34.
    [037] Figure 6 shows the concentrator 60 mounted on a hair appliance 70. In that figure, the concentrator 60 is configured as an accessory that can be detachably attached to the hair appliance 70. When the concentrator 60 is otherwise attached it non-conventional, the airflow of the hair appliance 70 is concentrated. In professional environments or in home use, it is often desirable to remove the concentrator 60 when it is configured as a detachable adapter when drying is complete. When concentrator 60 is removed, an alternative hair drying accessory can then be used with hair appliance 70.
    [038] Regardless of whether the features of the present invention are configured as an accessory with a hairdresser 70 or integral with a fan 26, the user only needs to hold the device 20 or hairdresser 70 with one hand, at the same time as selects the portion of hair to be treated. When the hair section is wrapped, the hair is pulled away from the wearer at the same time as concentrated air is applied.
    [039] When the device 20 is integral with the fan 26, the hair can be simultaneously heated and styled without the use of a hair dryer, which is very convenient for the user. Once device 20 is activated, bar 40 with projected bristles 42 can wrap a user's hair. The concentrated air in combination with the bar 40 with projecting bristles 42 envelops the user's hair, thus lifting the hair from the user's scalp. As a result, the wrapped section of hair is dried by the air exiting the one or more nozzles 34. As the user pulls the device 20 further away from their head, the hair is lifted and slides over the bristle portion 42 in a brush-like way. As a result, air moves through the hair, drying it evenly in a straightening mode. By drying the hair using this method, a smooth, voluminous finish is created.
    [040] When the concentrator 60 is used as an accessory for drying and styling hair, the user places the concentrator 60, as described above, in a hair appliance 70 having an outlet 62. The inlet portion 64 of the concentrator 60 is near the outlet 62 of the hair appliance 70 and the hair appliance 70 is activated to blow air normally heated through the concentrator 60.
    [041] Furthermore, it must be understood that aspects of the various modalities can be exchanged with each other, both in whole and in part. Furthermore, those skilled in the art will note that the foregoing description is by way of example only, and is not intended to be limiting of the invention, as further described in the appended claims.
