DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Turning to a first embodiment of the invention, as can be seen in FIGS. 1 to 4, there is provided an accessory generally designated as 2. The accessory 2 is in the form of an adapter for use with a hair dryer.

[0023] The accessory 2 comprises a body 4 generally formed of a housing 6 defining a cavity 8 therein (see FIG. 4). A rear opening 10 and a plurality of front openings 12 are provided in the housing whereby air may flow from the rear opening 10 to the front openings 12 via the cavity 8 of the housing 6. A retainer 14 is disposed at the center and in a front region of the body 4. A slot 16, which is circular in shape in this embodiment, is defined by the retainer 14 in which a substrate 18 may be retained. The retainer 14 comprises a circular collar 20 which is closed with a mesh 22 at its front end. A narrower neck region 24 having a number of lugs 26 is provided at a rear end of the retainer 14. The lugs 26 are resilient and can deform slightly when the substrate 18 is inserted to the slot 16 of the retainer 14. Once the substrate 18 is inserted in the slot 16, the lugs 26 will return to their normal position and the substrate 18 is securely held in the retainer 14.

[0024] The substrate 18 may be in the form of a tablet sized and shaped to fit tightly in the slot 16. The substrate 18 is made of a material adapted to absorb and be refilled with a scented medium, and preferably comprises cavities 27 for accommodating and retaining a suitable amount of the scented medium. Alternatively, the substrate 14 may be made with the scented medium. It is preferable that the substrate 14 can withstand repeated heating and cooling. One such suitable material of the substrate 14 is ceramic [i.e. Silicon oxide (Al2O3)] because it can withstand a high temperature although ocher suitable materials such as a sponge-type material may be used. The scented medium may preferably be aromatic oil (such as lemon or lavender aromatic oil) which is evaporable at an elevated temperature relative to an ambient temperature (i.e. room temperature]. The elevated temperature of heated air from a hair dryer is normally 45 C. or higher at which level an aromatic oil will usually evaporate. Yet another alternative is that the substrate 14 may be in the form of a disposable scented tablet which can be replaced when its aroma is exhausted.

[0025] At a rear end of the accessory 2, a connector 29 in the form of a number of slightly movable legs is provided. The connector 29 allows the accessory 2 to be connected with a front end of a hair dryer. In use, as the rear end of the accessory 2 is positioned in front of the hair dryer, the accessory 2 can be removably connected thereto by pushing towards the hair dryer as the legs deform slightly and clip to an inner rim of the front end of the hair dryer. Alternatively, other forms of connecting or retaining mechanisms may be provided to the accessory according to the invention. For example, the accessory may be adapted to be snap-fitted or screw-fitted to the hair dryer.

[0026] In use, a user before a hair drying/styling operation may add a suitable amount of a preferred scented medium to the substrate 18 in the retainer 14 of the accessory 2 which is then installed to the hair dyer. Once the hair dryer is turned on, air stream generated by a fan of the hair dryer will pass via a passageway defined by a housing of the hair dryer. On leaving the hair dryer, the air stream will enter the rear opening of the accessory 2 and leave the front openings of the accessory 2, passing through or around the substrate 18. In a situation where the scented medium is an aromatic oil and the operating mode of the hair dryer generates unheated air stream, minimal amount of the aromatic coil is evaporated because aromatic oils are usually evaporable only at an elevated temperature (i.e. usually 45 C. or above). In such case, the air stream leaving the front opening of the accessory 2 will have little or no scent of the aromatic oil. However, when the operating mode of the hair dryer generate heated air stream, heated air passing through or around the substrate will evaporate the aromatic oil and air flowing from the front openings of the accessory 2 will carry and is enhanced with the aroma of the oil. Hair blown, dried and styled by such air flowing will acquire the aroma as well. The use of the hair dryer with the accessory 2 according to the invention allows blow-drying and fragrance acquiring on the hair in one step. The emission of aroma by the substrate 18 is to be conveniently controlled by the heated or non-heated mode of the hair dryer as selected by the user. In an event that the substrate 18 is loaded with a scented medium which is evaporate but not dependent on temperature, scented air stream may be generated in whichever of the operation modes.

[0027]FIGS. 5 and 6 show a second embodiment of an accessory 32 also in the form of an adapter for use with a hair dryer. The accessory 32, similarly includes a retainer 34 for housing a substrate 36 and a connector 38 for connecting the accessory 32 with a hair dryer. The main difference between this embodiment and the first embodiment is that the accessory 32 is in the form of a concentrating adapter to confine air flowing from the hair dryer, while the accessory 2 shown in FIGS. 1 to 4 is in the form of an adapter for diverging air flowing from the hair dryer.

[0028]FIGS. 7 and 8 show a third embodiment of the invention in that an accessory 42 also in the form of an adapter which is similar to the accessories 2, 32 in the first and second embodiments. However, the necessary 42 is adapted to allow diffusing air flowing from a hair dryer. A substrate 44 is similarly situated in a retainer 46. It can also be seen that a rear portion 48 of the accessory 42 is sized and shaped to fit to an outer rim of a hair dryer.

[0029]FIG. 9 shows a substrate (18, 36 or 44) which may be used in any one of the accessories (2, 32 and 42). It can be seen that a plurality of the cavities 27 are provided for accommodating an aromatic oil.

[0030]FIG. 10 illustrates a fourth embodiment of the invention, and shows a cross section view of a hair dryer assembly 52 comprising a hair dryer incorporated with an adapter 54. The adapter 54 is generally similar to any one of the accessories (2, 32 and 42) in the first, second and third embodiments. The adapter 54 similarly comprises a retainer 56 having a substrate 58 therein and arranged in a front portion of the hair dryer. The adapter 54 also comprises a connector 60 for connecting to a front rim of the hair dryer.

[0031] It can be appreciated that the adapter 54, similar to the accessories in the other three embodiments, can be adapted to be removably and conveniently connected to the hair dryer. Alternatively, the hair dryer can be made integrally with the adapter 54. In the latter case, the retainer 56 can be designed such that the substrate 58 can be inserted therein from its front end

[0032] As clearly shown in FIG. 10, when the hair dryer assembly 52 is operational, air in drawn from its surroundings 62 into the rear end thereof, passing through a fan and a heater 64. Heated air will pass through or around the substrate 58 situated in the retainer 56. A scented medium received in the substrate 58, e.g. aromatic oil, on passing of the heat air, will evaporate and air leaving the adapter 54 will carry the aroma of the scented medium.
