Definitions

  • This invention relates to an accessory for a hair treatment device, such as a hair dryer or a diffuser, and a hair treatment device: incorporating such an accessory.
  • hair treatment devices such as hair dryers and curl diffusers, which are usually electrically operated.
  • Such hair treatment devices usually generate heated air flow to dry or heat up the hair of a user, e.g. for styling purposes.
  • Such conventional hair treatment devices usually have a handle: portion adjoining a barrel through which air exits the devices. The air (whether heated or not) exits the device in one direction only, usually along a longitudinal direction of the barrel. If the user would like to dry or heat up the hair of a larger area, he/she has to oscillate the device. In addition, if hot air is (e.g. inadvertently) only applied on a small portion of the hair of the user, that portion of the user's hair may be over-heated, thus damaging the hair.
  • US Patent Application Publication No. US 2005/0072019 A1 discloses an oscillating hair dryer nozzle assembly which attaches to a hand held electric hair dryer.
  • An oscillating nozzle is pivoted back and forth by forced air generated by an electric motorized fan within the hair dryer.
  • a propeller receives the forced air and rotates a propeller shaft which is coupled to a gear reduction assembly.
  • the gear reduction assembly converts the rotational motion of the propeller shaft into respective pivotal movement of the oscillating nozzle.
  • the oscillating nozzle automatically redirects the air flow in a plane.
  • the nozzle assembly is rotatably attached to the output barrel of a hair dryer body so that the oscillating nozzle can be rotated to pivot and redirect air flow in a different plane.
  • a hair treatment accessory in accordance with claim 1 and a hair treatment device incorporating said accessory.
  • Figs. 1 and 2 show a hair treatment device, being an electric hair dryer, and generally designated as 10, and an air deflector, being an accessory for a hair treatment device according to an embodiment of the present invention, and generally designated as 12.
  • the air deflector 12 is detached from the hair dryer 10; and in Fig. 2 , the air deflector 12 is releasably engaged with the hair dryer 10.
  • the hair dryer 10 and the air deflector 12 may collectively form a hair treatment device set, or part of a hair treatment device set including one or more other accessories which are selectively releasably engageable with the hair dryer 10.
  • the hair dryer 10 has an air entrance 14 and an air exit 16 defining an air passage therebetween.
  • An electrically operated air flow generator e.g. a fan
  • a heating element e.g. heating filaments
  • the heating element raises the temperature of the air entering the hair dryer 10 before exiting the hair dryer 10, e.g. for drying or heating up the hair of a user.
  • the hair dryer 10 has a number of buttons 18a, 18b, 18c for controlling, e.g. the on and off of the hair dryer 10, the speed of operation of the air flow generator (and in turn the rate of flow of air out from the hair dryer 10), and the temperature of the heating element (and in turn the temperature of air flow exiting the hair dryer 10).
  • the air deflector 12 has an air ingress 20 at one longitudinal end and an air egress 22 at an opposite longitudinal end.
  • the air ingress 20 and the air egress 22 define an air passageway (not shown) therebetween.
  • the longitudinal end of the air deflector 12 with the air ingress 20 is threaded, for releasable threaded engagement with the air exit 16 of the hair dryer 10.
  • air exiting the air exit 16 of the hair dryer 10 will enter the air ingress 20 of the air deflector 12. It is possible to have the air deflector 12 releasably engageable with the air exit 16 of the hair dryer 10 in other manners, e.g. by force fit or friction fit.
  • the air deflector 12 has a generally cylindrical housing 24 and a switch 26 the manner of operation and function of which will be discussed below.
  • a nozzle 28 is provided within the air deflector 12.
  • Figs. 7 to 12 show various views of the nozzle 28.
  • the nozzle 28 has an air inlet 30 at one longitudinal end and an air outlet 32 at an opposite longitudinal end, defining an air conduit 34 therebetween. It: should be noted that:
  • the nozzle 28 when the nozzle 28 is assembled within the air deflector 12, the nozzle 28 is freely hinged to the housing 24 for to-and-fro oscillation relative to the housing 24 about the axis of oscillation L-L within the confines of the housing 24, and within an angle of less than 180°.
  • the air deflector 12 includes a housing 24 comprising a front cover 42, a body 44 and an end piece 46, with a common ventral longitudinal axis M-M.
  • the nozzle 28 includes two diametrically opposite pins 48, 50.
  • the pin 48 is received within an upper hole 52 of the body 44 and the pin 50 is received within a lower hole 53 (see Fig. 16 ) of the body 44.
  • the nozzle 28 can thus freely oscillate: relative to the body 44 of the housing 24 about the axis L-L which joins the pins 48, 50.
  • the switch 26 is slidable to and fro along a slot 54 on an outer surface 56 of the body 44 in a direction along the bi-directional arrow G-G in Fig. 15 , which is parallel to the central longitudinal axis M-M of the housing 24.
  • the weight of the nozzle 28 is asymmetrically distributed about the longitudinal plane containing its central longitudinal axis A-A and its axis of oscillation L-L ensures that even when the nozzle 28 is at its centre position, the reaction force of air impinging on the inner surface of the nozzle 28 is not balanced, thus ensuring continuous oscillating movement of the nozzle 28. It is found in practice that the presence of the two rims 40 along the inner edge of the air outlet 32 of the nozzle 28 enhances the oscillating movement.
  • the end piece 46 includes an outer shell 64 and an inner funnel 66 which are integrally formed with each other.
  • An inner opening end 67 of the funnel 66 is received into the nozzle 28 through the air inlet 30 of the nozzle 28.
  • all air from the hair dryer 10 will enter the end piece 46 (and thus the housing 24 of the air deflector 12) through the funnel 66.
  • This also means that all air from the hair dryer 10 will enter the nozzle 28, to cause the nozzle 28 to oscillate. All such air will subsequently exit the air outlet 32 of the nozzle 28 and eventually the air egress 22 of the air deflector 32
  • the switch 26 is engaged with a wire spring 58 with a bent recess 60.
  • the switch 26 may be moved, e.g. manually by a user, to push the spring 58 so as to have the recess 60 engaged with a protrusion 62 extending upwardly from the nozzle 28, so as to prevent oscillation of the nozzle 28, thus locking the nozzle 28, even upon passing of air through the nozzle 28.
  • the user may subsequently move the switch 26 away from the protrusion 62 so as to disengage the wire spring 58 from the protrusion, thus unlocking the nozzle 28, allowing it to oscillate upon passing of air therethrough.
  • the air deflector 12 is discussed and shown as being engageable with the air exit 16 of the hair dryer 10 in a configuration in which the axis of oscillation L-L of the nozzle 28 is vertical (in the sense of Fig. 4 ), such that the nozzle 28 can oscillate horizontally (again in the sense of Fig. 4 ). It is envisaged that the air deflector 12 may be engaged with the air exit 16 of the hair dryer 10 in more than one configuration. In an alternative configuration, the air deflector 12 is engaged with the air exit 16 of the hair dryer 10 such that the axis of oscillation L-L of the nozzle 28 is rotated by 90°, and is thus horizontal (in the sense of Fig.
  • the nozzle 28 can oscillate up and down (again in the sense of Fig. 4 ).
  • the axis of oscillation L-L of the nozzle 28 may be slanted (in the sense of Fig. 4 ) such that the nozzle 28 can oscillate in a slanted manner (again in the sense of Fig. 4 ).
  • the air deflector 12, when engaged with the air exit 16 of the hair dryer 10 may be freely rotatable relative to the hair dryer 10 about an axis substantially parallel to the central longitudinal axis M-M of the air deflector 12, including the central longitudinal axis M-M of the air deflector 12, thus bringing about simultaneous corresponding rotation of the nozzle 28.
  • FIG. 17 to 26 A second exemplary air deflector, being an accessory for a hair treatment device according to another embodiment of the present invention, is shown Figs. 17 to 26 , generally designated as 12a.
  • the structure of the air deflector 12a is very similar to that of the air deflector 12 discussed above.
  • an air outlet 32a of a nozzle 28a hinged with and within the air deflector 12a for to-and-fro oscillation about an axis L a -L a relative to and within the confines of a housing 24a and within an angle of less than 180° is thicker on its left side 38a (in the sense of Fig. 20 ) than its right side 36a (again in the sense of Fig. 20 ).
  • a switch 26a engaged with the air deflector 12a has a locking plate 68a with a recess 70a facing a protrusion 62a of and fixed to the nozzle 28a.
  • Figs. 21 , 22 , 25 and 26 show the switch 26a. in an outer position in which the protrusion 62a of the nozzle 28a is clear of the recess 70a of the locking plate 68.
  • the nozzle 28a can oscillate within the housing 24a of the air deflector 12a and about its axis L a -L a upon passing of air therethrough.
  • the switch 26a is moved towards the nozzle 28a to its inner locking position, and when the nozzle 28a is in its centre position (as shown in Figs. 23 and 24 ), the protrusion 62a is received within the recess 70a. In such a scenario, the nozzle 28a cannot oscillate about the axis L a -L a relative to the housing 24a even upon passing of air therethrough.
  • the effect of the weight of the nozzle 28,28a being asymmetrically distributed about the longitudinal plane containing its central longitudinal axis A-A and its axis of oscillation L-L, L a -L a is brought about by having one side of the nozzle 28, 28a thicker than the other side. It is envisaged that such an effect can also be brought about in the following manners:
  • FIG. 27 is a cross sectional view of the air deflector 12, 12a, in which Fig. 27 shows the nozzle 28, 28a in a left-most position, Fig. 28 shows the nozzle 28, 28a in a centre position, and Fig. 29 shows the nozzle 28, 28a in a right-most position.
  • the nozzle 28, 28a will oscillate about the axis L a -L a and within the confines of the housing 24a so as to continuously change the direction in which the air exits the air deflector 12, 12a, as shown by the arrows T, S, R in Figs. 27, 28 and 29 respectively.
  • the air exiting the air deflector 12, 12a covers a wider area and a wider angle than in the absence of the air deflector 12, 12a.
  • the electric hair dryer has a High-Speed mode of operation and a Low-Speed mode of operation.
  • Frequency of Oscillation of Sample Air Deflector Mode of Operation Frequency of Oscillation High Speed 402 rounds per minute Low Speed 125 rounds per minute
  • the user Given the very high speed of oscillation of the air deflector, the user will not feel pulses of air flow from the hair dryer, but a continuous stream of air flow of an even temperature and of a wider area of coverage than with the hair dryer alone and without the air deflector.
  • the hair treatment device being an electric hair dryer. It is of course readily apparent to a person skilled in the art that the hair treatment device may be in other nature or forms, e.g. a diffuser.
  • the air deflector is disclosed as being releasably engageable with the air exit of the electric hair dryer. It is envisaged that the present invention also encompasses the arrangement in which a built-in air deflecting mechanism is provided in the air passageway way of an electric hair treatment device, such as a hair dryer or diffuser.
  • the hair treatment device e.g. a hair dryer or diffuser
  • the hair treatment device includes an air entrance and an air exit defining an air passageway therebetween, an air flow generator to draw air into the device through the air entrance and to drive the air out of the device through the air exit, and a nozzle in the air passageway downstream of the air flow generator.
  • the nozzle includes an air inlet and an air outlet, the air inlet being configured to receive all or at least part of the air flowing in the air passageway from the air flow generator, and thus from the air entrance, and the air outlet allows exit of the air received by the air inlet.
  • the nozzle is engaged with (e.g.
  • the hair treatment device for to-and-fro oscillation about an axis of oscillation and within an angle of less than 180° relative to and within the passageway to continuously change the direction of the air exiting the nozzle, and thus the hair treatment device.
  • the nozzle is preferably positioned close to the air exit of the hair treatment device. All other features of the air deflector discussed above (e.g. the locking/unlocking mechanism, the shapes and construction of the nozzle, and different possible orientations of the nozzle relative to the hair treatment device) may also be incorporated in this arrangement. It is also envisaged that the nozzle may be freely rotatable relative to the passageway about an axis substantially parallel to the central longitudinal axis A-A of the nozzle, including the central longitudinal axis A-A of the nozzle.
