DETAILED DESCRIPTION
[0030] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
[0031] Various exemplary attachments or accessories for use with a hair care appliance, such as a hair dryer, are provided herein. In one embodiment, an attachment in the form of a brush accessory is provided having bristles configured to engage with hair during brushing or styling. The brush attachment can also include outlets configured to divert air flowing from the outlet of the hair care appliance and into the brush attachment so as to provide air via outlets of the brush attachment. In certain embodiments, the air flow can be diverted evenly along the entire length of the brush attachment based on the shaped regions of a baffle provided within the brush attachment. In other aspects, a mating feature is provided to enable an attachment, such as a brush attachment, to rotate relative to the hair care appliance to which it is attached so that a user can rotate the attachment and air flow to apply a desired styling effect more easily.
[0032] Advantageously, these features can provide an enhanced styling experience, particularly for curling or brushing hair compared to other attachments for a hair care appliance. The provision of a uniform amount and velocity of air flow along an entire length of an attachment can enhance the performance of the attachment so that the entire length of the attachment can be used to style hair and a greater amount of hair can be styled at one time. Additionally, the rotating use of an attachment can allow a user to direct the air flow to desired portions of their hair more easily than non-rotating attachments, which may only have fixed outlet locations.
[0033]
[0034] The body 120 of the brush attachment 100 can having a variety of shapes and sizes, and can be formed from various components. In the illustrated embodiment, the body 120 includes a frame 210 having a cover 205 disposed there around, as shown in
[0035] The illustrated frame 210 has an elongate, hollow cylindrical shape with an inner lumen 215 extending there through and defining a fluid flow path F from the inlet 135 at the proximal end 105 of the attachment 100 to a plurality of outlets 140. The plurality of outlets 140 can be formed in the frame 210 at various locations and in various patterns. As shown in
[0036] The frame 210 can further include a plurality of bristles 130 positioned about a circumference and along the length of the frame 210 and extending radially away from the frame 210. As shown in
[0037] As indicated above, the body 120 can also include a cover 205 positioned over the frame 210. The cover 205 can thus have a size that substantially corresponds to a size of the frame 210 to form a close fit with the frame. As shown in
[0038] As further shown in
[0039] In some embodiments, the cover 205 can include a coating for retaining heat and distributing heat about the cover 205. The coating can be formed from any thermally conductive material, such a metal material. In other embodiments, the cover 205 can be eliminated and the frame can be coated.
[0040] As further shown in
[0041] As shown in
[0042] As further shown in
[0043] The distal region 815 can include a frustoconical housing 830 coupled to the support elements 825 of the intermediate region 815. The housing 830 can have a tapered profile including a smaller diameter adjacent to the intermediate region and larger diameter at the distal end of the baffle 220 (e.g., the distal end at which the plate 705 is located). The housing 830 can have a hollow interior 835 for weight reduction of the baffle. The tapered profile of the housing 830 can advantageously increase air pressure of fluid flowing along the fluid flow path F adjacent to the distal region of the baffle 210. As a result, fluid reaching the distal region 815 of the baffle 210 can be conveyed through the outlets 140 at the same velocity and volume as fluid exiting the outlets 140 arranged adjacent to the intermediate region 810 and the proximal region 805. This design can thus provide a consistent volume and velocity of fluid from the brush attachment 100 along its entire length.
[0044] In order to mount the baffle 220 to the frame 210, the baffle 220 can have a frame mounting plate 705 at a distal end thereof, as shown in
[0045] Referring back to
[0046] As previously indicated, a mating assembly for rotatably mating an attachment to a hair care appliance is also provided. While the mating assembly is disclosed in connection with brush attachment 100, the mating assembly can be utilized with any type of accessory.
[0047] In the exploded view of the brush attachment 100 shown in
[0048] In
[0049] The rotating portion 310 of the mating assembly 115 can be received within the appliance mating portion 305. For example, the proximal end 915 of the rotating portion can be received within the opening 935 and abut the protrusion 940 of the appliance mating portion 305. The proximal end can include a gasket 920, such as an o-ring or the like, configured to allow the rotating portion 310 to rotate within the appliance mating portion 305. The rotating portion 310 can couple to the frame 210 via one or more tabs 925 which can project away from the proximal end 915 of the rotating portion 310 and toward the frame 210. The tabs 925 can be received within slots 930 provided in the proximal end of the frame 210. The tabs 925 can include engagement features such as protrusions, detents, or angled face portions which, when received within the slots 930, can secure the rotating portion 310 to the frame 210. A variety of coupling or engagement mechanisms can be envisioned to join the rotating portion 310 and the frame 210 and is not limited to tabs and slots. In some embodiments, the coupling or engagement mechanisms of the rotating portion 310 and the frame 210 can include a friction fit, magnets, rivets, screws, protrusions, grooves, or the like. The coupling of the rotating portion 310 and the frame 210 can enable the attachment 100 to rotate freely when the proximal end 135 of the attachment 100 is coupled to a hair care attachment 100. The appliance mating portion 305 can be releasably secured to the outlet end of a hair care appliance and the attachment 100 can rotate freely relative to the hair care appliance when attached.
[0050] When fully assembled, the attachment mating assembly 115 can couple with the frame 210, as shown in
[0051] The outlet end of the hair care appliance can include an attachment mating portion 1100, as shown in
[0052] The attachment mating portion 1100 can also include at least one recession 1110 configured to receive a tab or protruding portion of an attachment actuator assembly of the hair care appliance. The recession 1110 can have a width 1115 corresponding to a width of the tab or protruding portion of the attachment actuator assembly. As the attachment 100 is mated with the attachment mating portion 1100, the protrusions 1105 can travel into the slots 1005 configured on the appliance mating portion 305 of the attachment. Once travel is complete the user can release a latch of the attachment actuator assembly so that the tab portion of the attachment actuator assembly travels into the recession 1110 locking the attachment in place to prevent rotation of the attachment 100 on the hair care appliance. The attachment mating portion 1100 can also include an opening 1120 along the circumference of the bottom portion of the attachment mating portion 1100. The opening 1120 can receive the attachment actuator assembly therein. The opening 1120 can have a width 1125 corresponding to a width of the attachment actuator assembly.
[0053] The attachment actuator assembly 1200 of the hair care appliance can be seen in more detail in
[0054] In
[0055] In use, the attachment 100 can be used to dry, brush, curl, or otherwise style hair by coupling the attachment 100 to a hair care appliance and engaging the attachment 100 with the user's hair. The hair care appliance can generate air flow that is received at the inlet 135 of the attachment 100 and directed through the outlets 140 in a uniform, consistent, and even flow along the entire length of the attachment 100. A user can hold the hair care appliance coupled with the attachment 100 attached thereto in one hand and can grasp the end cap 125 in the other hand. When applying a curling styling technique, the user can bring the attachment 100 into contact with their hair and can rotate the end cap 125 so as to rotate the attachment 100 relative to the hair care appliance such that the user's hair is wrapped around the attachment 100. The even, consistent air flow provided along the entire length of the attachment 100 can advantageously allow the user to effectively curl a larger amount of hair and create a more well-formed, circular or helix-shaped curl than other styling attachments. The user can leave their hair wrapped around the attachment 100 for a period of time to set a curl in the wrapped hair. At the end of a period of time, the user can rotate the end cap, and thus the attachment 100, in the opposite direction to release the hair from the attachment 100. When applying a brushing styling technique, the user can bring the attachment 100 into contact with their hair and can maintain the end cap 125 in a fixed position, thereby eliminating or reducing rotation of the attachment 100. The user can bring the attachment 100 into contact with their hair and pull down away from the top of their head so that the air flow provided along the length of the attachment 100 engages with their hair during each brush stroke. The user can repeatedly brush their hair in this manner to dry wet hair or brush wet or dry hair. Because the air flow is provided along the entire length of the attachment 100 in an even, consistent distribution, a greater amount of hair can be dried and the time to dry wet hair can be reduced compared to other attachments.
[0056] The improved brush attachments described herein and configured for use with a hair care appliance produce a number of advantages. For example, the rotating body of the brush attachment can rotate relative to the hair care appliance to which it is coupled thereby allowing a user to more efficiently curl a greater quantity of hair than non-rotating brush attachments. As a result, the time required to curl hair can be reduced and more defined, cylindrical shaped curls can be achieved. Additionally, the baffle within the brush attachment can deliver an even volume of air flow along the length of the curling attachment. For example, the proximal region of the baffle can intersect the fluid flow path received at the inlet of the brush attachment to direct the air flow radially toward the surface of the attachment. The tapered, frustoconical shape of the distal region of the baffle can increase air pressure of the fluid flow as it passes toward the distal end of the baffle to ensure air is uniformly directed toward the outlets at the distal end of the attachment. The distal region of the baffle can be hollow to provide an attachment of reduced weight that is easier for a user to handle.
[0057] As used herein, the term proximal can define a location of an element that is upstream of the fluid flow path F and thus closer in proximity to the outlet of a hair care appliance to which the attachment 100 can be coupled. The term proximal can also refer to a location that is closer to a handle of the hair care appliance at which the user may grasp the hair care appliance. The term distal can define a location of an element that is downstream of the fluid flow path F and thus further away from the outlet of the hair care appliance. A distal location will be opposite a proximal location and vice versa. The term distal can also refer to a location that is farther away from the handle of the hair care appliance.
