[0068] 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.
[0069] Various exemplary hair care appliances and accessories for use with a hair care appliance are provided herein. A hair care appliance can be a hair dryer or any other hair care appliance known in the art. In an exemplary embodiment, a hair care appliance is in the form of a hair dryer that has an air inlet, an air outlet, and various components that facilitate use and operation of the hair care appliance, such as a fan, a motor, and a heater. The hair care appliance is configured to releasably attach to a plurality of accessories (also referred to herein as “attachments, ” “hair care attachments, ” and “hair care accessories” ) . The hair care appliance is configured to releasably attach to only one of the accessories at a time to allow a user to select which accessory is appropriate for the particular hair care desired. The hair care appliances and accessories described herein may enhance the overall styling experience, regardless of user skill, and provide a modular styling device that can adapt to a variety of styling needs via a broad selection of attachments configured for use with the hair care appliance. Examples of accessories include a brush, a curler, and a concentrator.
[0070] In general, the hair care appliance and attachments described herein are configured to couple so that the hair care appliance and the attachment coupled to the hair care appliance are in electrical communication. The electrical connection is configured to allow power to be conveyed from the hair care appliance to the attachment coupled to the hair care appliance. Conventional hair care appliances and their attachments may not include the ability to transmit power to an attachment coupled to the hair care appliance. As a result, users may perform certain styling methods poorly and the resulting hair styling may be undesirable or unintended, causing a negative user experience. In contrast, the hair care appliances and attachments described herein may provide a more robust styling experience by conveying power from the hair care appliance to the attachment coupled to the hair care appliance. The power provided to the attachment from the hair care appliance is configured to provide power to one or more components of the attachment to be electrically powered components without the attachment needing on on-board power supply, which may reduce cost and / or weight of the attachment, and without the attachment needing to be independently connected to an external power supply. The attachment having reduced cost may reduce manufacturing cost and thus may reduce consumer purchase cost. The attachment having reduced weight may improve user experience since a lighter weight attachment at an end of the hair care appliance may make the hair care appliance with attached attachment easier for a user to hold and move around as hair is dried and / or styled. The attachment not needing to be independently connected to an external power supply may improve user experience by not requiring the user to take an action connecting the attachment to a power supply independent of any action that may be needed to connect the hair care appliance to a power supply such as by plugging a cord into an outlet.
[0071] The electrical connection is configured to allow data signals to be conveyed between the hair care appliance and an attachment coupled to the hair care appliance. Conventional hair care appliances and their attachments may not include the ability to transmit data signals to or from an attachment that is coupled to the hair care appliance. As a result, users may perform certain styling methods poorly and the resulting hair styling may be undesirable or unintended, causing a negative user experience. In contrast, the hair care appliances and attachments described herein may provide a more robust styling experience by allow data signals to be transmitted from the hair care appliance to the attachment coupled to the hair care appliance and / or from the attachment to the hair care appliance. For example, the attachment can include a sensor (e.g., an negative temperature coefficient (NTC) or other type of temperature sensor, a moisture sensor, etc. ) configured to be powered with power supplied to the attachment from the hair care appliance, which may enable automated operation of the hair care appliance to ensure the user is employing the hair care appliance in a manner that will generate the best results possible for a desired styling method, e.g., by a microcontroller or other electronic controller of the hair care appliance using a data signal indicative of data monitored by the sensor in controlling one or more settings of the hair care appliance, such as heat level and / or air flow level. For another example, using a data signal from the attachment indicative of a type of the attachment that is attached to the hair care appliance, a user can receive indications of feedback via a user interface of the attachment and / or a user interface of the hair care appliance indicating at least one setting (e.g., timing, temperature, etc. ) recommended to achieve optimal styling results for that particular type of attachment.
[0072] Various embodiments of hair care appliances and attachments configured to be releasably coupled to hair care appliances are further described, for example, in U.S. Pat. Pub. No. 2024 / 0245185 entitled “Hair Care Appliance With Powered Attachment” published on July 25, 2024, U.S. Pat. Pub. No. 2024 / 0245186 entitled “Hair Care Accessories” published on July 25, 2024, U.S. Pat. Pub. No. 2024 / 0245190 entitled “Identification Of Hair Care Appliance Attachments” published on July 25, 2024, and U.S. Pat. Pub. No. 2024 / 0245193 entitled “Hair Care Appliance With Powered Attachment” published on July 25, 2024, which are each hereby incorporated by reference in their entireties.
[0073] FIGS. 1 and 2 illustrate one exemplary embodiment of a hair care appliance 100. The illustrated hair care appliance 100 has straight and bent configurations, as respectively shown, however the hair care appliance 100 can have various other configurations. For example, in some embodiments, a hair care appliance can have only a straight configuration. For another example, in some embodiments, a hair care appliance can have only a bent configuration.
[0074] As in this illustrated embodiment, the hair care appliance 100 can generally include a handle 110 movably coupled to a body 120 by a rotational hinge joint 124. In the straight configuration, shown in FIG. 1, the hair care appliance 100 has a generally elongate cylindrical shape. The hair care appliance 100 has an inlet 112 at a first end of the hair care appliance 100 and an outlet 122 at a second end of the hair care appliance 100. The handle 110 has the inlet 112 at the first end of the hair care appliance 100, and the body 120 has the outlet 122 at the second end of the hair care appliance 100. A fluid flow path P (shown as a dashed line) is formed between the inlet 112 and the outlet 122. The rotational hinge joint 124 formed between the handle 110 and the body 120 is configured to articulate via user operation to alter the configuration of the hair care appliance 100 and the fluid flow path P from the straight configuration to the bent configuration (also referred to herein an as “angled configuration” ) . As shown in FIG. 2, in the angled configuration, the handle 110 and the body 120 are angled relative to one another as a result of articulation of the rotational hinge joint 124. As a result, as shown in FIG. 2, the fluid flow path P shown by a dashed line is angled between the handle 110 and the body 120. In FIG. 1, the fluid flow path P is substantially straight from the inlet 112 to the outlet 122.
[0075] A person skilled in the art will appreciate that the hair care appliance 100 can be operated while the rotational hinge joint 124 is unlatched, and / or while the rotational hinge joint 124 is rotated to any position that is between the position of the rotational hinge joint 124 in the straight configuration and the angled configuration. In other aspects, the hair care appliance 100 and the rotational hinge joint 124 can be configured to prevent over-rotation of the rotational hinge joint 124 beyond its position in the angled configuration. The hair care appliance 100 is configured to be selectively configured by a user in the straight configuration of FIG. 1, in the angled configuration of FIG. 2, or in a rotated configuration that is an angled configuration between those of the straight configuration of FIG. 1 and the angled configuration of FIG. 2. The hair care appliance 100 can be configured in a fully straight configuration, as shown in FIG. 1, in which the rotational hinge joint 124 locks the body 120 so as to be substantially longitudinally aligned with the handle 110. The hair care appliance 100 can be configured in a fully bent configuration, as shown in FIG. 2, in which the rotational hinge joint 124 locks the body 120 at an angle relative to the handle 110. The hair care appliance 100 can also be configured in the rotated configuration in which the rotational hinge joint 124 positions the body 120 relative to the handle 110 in a range of angled positions that are in between those of the fully straight configuration and the fully angled configuration. At any angled configuration, the fluid flow path P will be angled between the handle 110 and the body 120 and thus from the inlet 112 to the outlet 122.
[0076] The hair care appliance 100 includes various internal electrical components 126 configured for operating the hair care appliance 100. In general, as in this illustrated embodiment, the handle 110 can include the electrical components 126 that are configured to control operation of a fan assembly 128 disposed within the handle 110 and a heater assembly 132 disposed in the body 120. In an exemplary embodiment, as shown, the fan assembly 128 is placed downstream of the rotational hinge joint 124 and in proximity of the heater assembly 132, which is disposed upstream of the rotational hinge joint 124. This relative positioning of the fan assembly 128 and the heater assembly 132 may help improve fluid flow within the hair care appliance 100. The fan assembly 128 is configured to generate a fluid flow along the fluid flow path P such that air is drawn into the inlet 112, passes through the handle 110, and into the body 120 to be exhausted via the outlet 122. As the air passes through the body 120, the air is heated via the heater assembly 132.
[0077] The electrical components 126 are configured to couple to a power supply. FIG. 3 illustrates a power supply cord 130 extending from a proximal base of the handle 110. The power supply cord 130 has a terminal end (not shown) configured to couple to a power source, e.g., the terminal end can be configured to plug into an electrical outlet. The power supply cord 130 includes internal electrical wiring configured to deliver power to the electrical components 126 in the handle 110. The power supply cord 130 may be connected to an electronics housing containing the electrical components 126, which as in this illustrated embodiment can include at least one controller or printed circuit board (PCB) as shown in FIG. 4.
[0078] In some embodiments, instead of or in addition to being configured to couple to an external power supply as with the power supply cord 130 in the illustrated embodiment, a hair care appliance can have an on-board power supply, such as a battery or other power supply. Having an on-board power supply may allow for at least some functions of the hair care appliance to be provided without any externally provided power. For example, a light may be illuminated using an on-board power supply to indicate a condition of the hair care appliance. For another example, a user interface may display information to a user using an on-board power supply.
[0079] Referring again to FIG. 3, the proximal base of the handle 110 includes a filter assembly 116 configured to filter air drawn in through the inlet 112. In the illustrated embodiment, the filter assembly 116 extends around a proximal end portion of the handle 110 but is not formed in an end wall of the handle 110. Thus, fluid F is configured to drawn in circumferentially around the sidewalls of the handle 110. The illustrated filter assembly 116 includes an inlet housing 140 that is generally C-shaped and that is flexible for allowing the inlet housing 140 to be removed for cleaning. A user interface 138 intersects the inlet housing 140 in this illustrated embodiment. The inlet housing 140 has a plurality of holes through which the fluid F is configured to flow into the fluid flow path P. The holes can have any configuration and can be arranged in any pattern. The inlet housing 140 is configured to cover a filter 142 positioned behind the inlet housing 140, as shown in FIG. 4 in which the inlet housing 140 is omitted. The filter 142 can be a porous element, as shown, configured to block debris and hair that may have entered the inlet housing 140, thus preventing debris from entering the fluid flow path P. As further shown in FIG. 4, the electrical components 126 are positioned just downstream of the filter 142 and positioned upstream of the fan assembly 128, thus the fluid flow path P flows over and around the electrical components 126 as the fluid F is drawn toward and into the fan assembly 128 in operation. This relative positioning of the electrical components 126 and the fan assembly 128 may aid in cooling the electrical components 126.
[0080] The handle 110 also includes the user interface 138 configured to enable the user to provide inputs for operating the hair care appliance 100, as shown in FIG. 5. In particular, as in this illustrated embodiment, the user interface 138 can include one or more actuators (e.g., buttons, switches, etc. ) for powering the hair care appliance 100 on and off, adjusting a temperature setting of the heater assembly 132 (and thus adjusting a temperature of the fluid F heated by the heater assembly 132) , and adjusting a fan speed of the fan assembly 128 (and thus adjusting a velocity of the fluid F expelled via the outlet 122) . The user interface 138 also includes one or more actuators for powering or otherwise controlling an accessory attached to the hair care appliance 100, as will be discussed in more detail below. The user interface 138 also includes an actuator for disengaging the heating assembly 132 thus providing a cool, non-heated fluid from the outlet 122. In some embodiments, the user interface 138 can include one or more light emitting diodes (LEDs) , and / or other type of light, configured to provide a visual indication of an operating mode of the hair care appliance 100. In some embodiments, the user interface 138 can include one or more speakers configured to provide an audible indication of an operating mode of the hair care appliance 100. In some embodiments, the user interface 138 can include one or more haptic feedback mechanisms configured to provide a tactile indication, such as a vibration, of an operating mode of the hair care appliance 100.
[0081] While the user interface 138 can be positioned at various locations, in an exemplary embodiment, the user interface 138 extends longitudinally along at least a portion of the handle 110. As shown in FIG. 5, the user interface 138 in this illustrated embodiment extends along the base of the handle 110, intersects the filter assembly 116 as shown, and extends toward the rotational hinge joint 124, terminating a small distance from the rotational hinge joint 124. The user interface 138 is provided on a scalloped portion 136 of the handle 110 in this illustrated embodiment. The scalloped portion 136 includes raised edges along opposed lateral sides of the user interface 138 configured to facilitate gripping of the handle 110 by a user. The user interface 138 extends between a first handle housing 114a of the handle 110 and a second handle housing 114b of the handle 110 in this illustrated embodiment. In another embodiment, the user interface 138 can intersect the filter 142.
[0082] In an exemplary embodiment, electrical wiring coupling the user interface 138 to the electrical components 126 is routed to the sides of the user interface 138, and not directly under the user interface 138, to ensure that the fluid flow path P is not restricted or has limited fluid flow.
[0083] As indicated above, the user interface 138 can include one or more actuators configured to control operation of the hair care appliance 100 based on user inputs. For example, the user interface 138 can include a blow-out feature 144, which is shown as a button in this illustrated embodiment, as an actuator. Actuation of the blow-out feature 144 is configured to cause the heater assembly 132 to shut off so that only non-heated air is exhausted through the outlet 122. In some embodiments, the blow-out feature 144 can be located remotely from the user interface 138 or within the user interface 138 but remotely from other features of the user interface 138.
[0084] The user interface 138 can also include a fan setting feature 146, which is shown as a button in this illustrated embodiment, as an actuator. Actuation of the fan setting feature 146 is configured to control a speed of the fan assembly 128. The fan setting feature 146 is configured to be repeatedly selectable to generate high, medium, and low velocity fluid flow by the fan assembly 128, although other fan settings are possible.
[0085] The user interface 138 also includes a temperature setting feature 148, which is shown as a button in this illustrated embodiment, as an actuator. Actuation of the temperature setting feature 148 is configured to control a temperature of the heater assembly 132 and thus the fluid flow exiting the outlet 122 of the hair care appliance 100. The temperature setting feature 148 is configured to be repeatedly selectable to heat the fluid flow to very high, high, medium, or low temperatures. In some embodiments, the high temperature setting can cause the heater assembly 132 to heat the fluid flow to 100 degrees C.
[0086] As further shown in FIG. 5, the user interface 138 includes a power feature 150, which is shown as a button in this illustrated embodiment, as an actuator. Actuation of the power feature 150 is configured to control provision of power from the power supply to the electrical components 126 of the hair care appliance 100, and / or to electrical components of an accessory releasably coupled to the hair care appliance 100 as discussed further below. The user interface 138 also includes one or more tactile features 152, as indicated above. The tactile features 152 can, as in this illustrated embodiment, be raised edges or gripping features at an edge of the scalloped portion 136 that are configured to improve the user’s grip and manual dexterity when holding or operating the hair care appliance 100.
[0087] In some embodiments, the actuators (e.g., the blow-out, fan setting, temperature setting, and power features 144, 146, 148, 150) of the user interface 138 can be configured to avoid accidental engagement by the user. For example, one or more of the blow-out, fan setting, temperature setting, and power features 144, 146, 148, 150 of the user interface 138 can be recessed and require explicit engagement to trigger a particular user engagement feature. The low-profile or recessed design of the actuators of the user interface 138 is configured to enable a user to operate the hair care appliance 100 without mistakenly contacting an unintended actuator. In some embodiments, any of the actuators of the user interface 138 described herein can be configured with lighting or illuminated elements that can illuminate an actuator or surface of the user interface 138, such as an inner or under surface of the user interface 138. The arrangement and styling of the user interface features described herein can be provided in a variety of non-limiting configurations on the handle 110 of the hair care appliance 100 described herein.
[0088] The hair care appliances described herein, such as the hair care appliance 100 of FIGS. 1-5, include a variety of features configured to improve the ease of styling hair, heating hair, and the longevity of hair styles applied using the hair care appliance. For example, in one embodiment, the hair care appliance includes an attachment mating assembly configured to couple the hair care appliance to a selected one of various attachments, which can be powered attachments. The use of powered attachments may advantageously enhance hair styling by positioning one or more electronic components, e.g., a heating element, a sensor, etc., in the attachment and thus closer to the hair being styled than if the electronic components were in the hair care appliance. Powered attachments can also include a user interface, similar to the user interface 138 of FIGS. 3 and 5 discussed above, configured to provide a user with visual, audio, and / or haptic feedback about the styling process and / or operation of the hair care appliance to which the powered attachment is releasably coupled. A user’s styling experience may be enhanced using powered attachments that can be easily coupled to the hair care appliance via the attachment mating assembly configured to couple with an attachment mating mechanism of a selected powered attachment. Providing power and / or communications circuitry between the hair care appliance and a powered attachment via the attachment mating mechanism may expand the operation and function of the hair care appliance.
[0089] FIG. 6 illustrates one exemplary embodiment of a hair care appliance 200 having an attachment mating assembly 202 configured to couple an attachment 204 to the hair care appliance 200. In this embodiment, the attachment 204 is a curling attachment configured to curl hair. The curling attachment 204 in this illustrated embodiment has a generally elongate cylindrical configuration with a plurality of heating plates thereon. The illustrated curling attachment 204 further includes a user interface 206 at a distal end of the attachment 204. In some embodiments, as in this illustrated embodiment, the hair care appliance 200 can also include a user interface 208 at a distal end of the hair care appliance 200. In some embodiments, one or both of the user interfaces 206, 208 can include at least one LED and / or other type of light, at least one speaker, and / or at least one haptic feedback mechanism. Although FIG. 6 shows a curling attachment 204, to the hair care appliance 200 is configured to releasably attach to a variety of other types of attachments via the attachment mating assembly 202.
[0090] The attachment mating assembly 202 is provided at the distal end of the hair care appliance 200 and surrounds an outlet 210 of the hair care appliance 200. As shown in FIG. 7, the attachment mating assembly 202 is in the form of a ring-shaped body having mating features thereon. An attachment coupling 212 provided on an attachment (such as the curling attachment 204 or another attachment) is configured to be coupled to the attachment mating assembly 202. In the illustrated embodiment of FIG. 7, the attachment coupling 212 is likewise in the form of a ring-shaped body having mating features 234 thereon configured to mate with the corresponding mating features on the attachment mating assembly 202. The attachment coupling 212 includes an opening 218 through which, with the attachment that includes the attachment coupling 212 coupled to the hair care appliance 200, air flow exiting the outlet 210 of the hair care appliance 200 enters the attachment. The attachment coupling described herein, such as but not limited to the attachment coupling 212, is also referred to herein as an “attachment collar. ”
[0091] While various mating features can be utilized to mate the attachment coupling 212 to the attachment mating assembly 202, in the illustrated embodiment the attachment coupling 212 includes a plurality of projections 236, 238 (see FIG. 8B) configured to extend into corresponding slots 214, 242 (see FIGS. 7 and 9) formed in the attachment mating assembly 202. The attachment that includes the attachment coupling 212 is thus configured to be coupled to the attachment mating assembly 202 by aligning the projections 236, 238 with the slots 214, 242 of the attachment mating assembly 202 and applying a linear force substantially along a longitudinal axis of the attachment and the hair care appliance 200. The attachment mating assembly 202 further includes a rotatable release mechanism 220, such as a rotatable ring as shown (see FIG. 9) , configured to engage the projections 236, 238 within the slots 214, 242 to prevent removal thereof. The ring 220 is spring-biased to an engaged position. Thus, during insertion of the projections 236, 238 into the slots 214, 242, the projections 216 are configured to cause the ring 220 to rotate out of the way, e.g., to move out of the engaged position, thus allowing the projections 236, 238 to fully extend into the slots 214, 242. Once fully seated in the slots 214, 242, the spring-bias of the release mechanism 220 is configured to cause the rotatable ring to return to the initial, engaged position, thereby engaging the projections 236, 238 within the slots 214, 242 to retain the projections 236, 238 therein, thus retaining the attachment coupling 212 to the attachment mating assembly 202. The release mechanism 220 is configured to secure the attachment coupling 212 to the attachment mating assembly 202 so that the attachment that includes the attachment coupling 212 is securely fixed and immovable relative to the hair care appliance 200 until the release mechanism 220 is actuated, as discussed herein, to allow release of the attachment from the hair care appliance 200. Accordingly, the release mechanism 220 is configured as a lock. The release mechanism 220 is configured to be rotated by a user to disengage the release mechanism 220 from the attachment coupling 212, e.g., to unlock the attachment, to allow removal of the attachment from the hair care appliance 200.
[0092] As further shown in FIG. 7, the attachment coupling 212 includes a plurality of electrical connectors 222. The electrical connectors 222 are configured to mate with corresponding electrical connectors 224 provided in the attachment mating assembly 202. A variety of connector types can be used, such as male / female connectors, keyed connectors, locking connectors, pogo pins, crown spring connectors, crimp connectors, or blade connectors. In this illustrated embodiment, the attachment coupling’s electrical connectors 222 are male pins configured to be received within the corresponding attachment mating assembly’s electrical connectors 224 as female sockets. Additionally, the arrangement of the electrical connectors 222, 224 can vary. For example, in some embodiments, the attachment coupling 212 can include female connectors and the attachment mating assembly 202 can include male connectors, or vice versa. The location or arrangement of the electrical connectors 222, 224 on the attachment mating assembly 202 and the attachment coupling 212 can also vary. For example, as shown in FIG. 7, two sets of adjacent 4-pin connectors are shown in corresponding locations about circumferences of the attachment mating assembly 202 and the attachment coupling 212. In some embodiments, the sets of electrical connectors 222, 224 can be opposite to one another or positioned separately from one another around the circumferences of the attachment mating assembly 202 and the attachment coupling 212. In some embodiments, a set of connectors can include 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 connectors. The arrangement of the electrical connectors 222, 224 may provide the hair care appliance 200 with a small diameter body or housing, ease of wire routing, and can reduce airflow obstruction through the hair care appliance 200.
[0093] The electrical connectors 222 of the hair care appliance 200 and the electrical connectors 224 of the attachment, with the attachment coupled to the hair care appliance 200, are configured to be communicatively coupled via wiring to electrical components of the hair care appliance 200, e.g., any one or more of a PCB, a fan assembly, a motor, a user interface, a switch, etc. The electrical connectors 222, when mated to the electrical connectors 224, are configured to be communicatively coupled via wiring to electrical components of the attachment, e.g., any one or more of a heating element, a heating assembly, a sensor, a user interface, etc. The electrical connectors 222, 224, when connected, are configured to convey power signals and / or data signals between the hair care appliance 200 and the attachment.
[0094] For example, in one embodiment, a first set of the electrical connectors 222, 224 is configured to convey power between the hair care appliance 200 and the attachment coupled thereto, or vice versa. The first set can include first and second power pins, first and second neutral pins, and a local earth or ground pin. A second set of the electrical connectors 222, 224 is configured to convey data between the hair care appliance 200 and the attachment coupled thereto, or vice versa. The second set can include first and second user interface control pins, first and second sensor data pins, and a spare pin.
[0095] As indicated above, the attachment coupling 212 can be, as in this illustrated embodiment, include a ring-shaped structure having an opening 218 therein for air flow to pass from the outlet 210 of the hair care appliance 200 into the attachment coupled with the hair care appliance 200. The attachment coupling 212 includes a first, distal side, as shown in FIG. 8A, including housings 226 at which the electrical connectors 222 are configured to receive wires from the electrical components of the attachment that includes the attachment coupling 212. The first side also includes a collar 228 extending distally away from the first side. The collar 228 is configured to secure the attachment coupling 212 to the attachment.
[0096] An opposite, second, proximal side of the attachment coupling 212, shown in FIG. 8B, includes a plurality of pins 230 that extend proximally from the housings 226 on the first side of the attachment coupling 212 and are configured to be received by receiving portions of the electrical connectors 222 of the attachment mating assembly 202 of the hair care appliance 200. The second side also includes a second collar 232 extending proximally away from the second side. The second collar 232 includes engagement features 234 configured to align and secure the attachment coupling 212 within the attachment mating assembly 202. For example, as shown, the second collar 232 includes the protrusions 216 and the engagement features 234. The engagement features 234 include a pair of features configured to engage with the release mechanism 220 of the attachment mating assembly 202. A first element 236 of the pair of engagement features 234 can be, as shown, a protrusion extending radially away along their length from the second collar 232. The first element 236 is configured to be received through the slots 242 of attachment mating assembly’s lock ring 244 (see FIGS. 7 and 9) and seated within the slots 214 (see FIG. 9) of the housing of the hair care appliance 200. A second element 238 of the pair of engagement features 234 includes angle-faced protrusions co-located on the second collar 232 with the first engagement features 236 immediately adjacent to the second side. The angled faces of the second elements 238 are configured to be received through the slots 242 (see FIGS. 7 and 9) of the lock ring 244 and to engage corresponding angle-faced protrusions 240 on the release mechanism 220.
[0097] As indicated above, the attachment mating assembly 202 of the hair care appliance 200 includes a lock ring 244 configured to secure the release mechanism 220 and the electrical connectors 222 in place at the distal end of the hair care appliance 200. The lock ring 244 includes projecting tabs 246 extending proximally toward the hair care appliance 200 that pass through the release mechanism 220 and engage with the slots 214 provided on the inner surface of a hair care appliance body or housing 260. The projecting tabs 246 are configured to secure the lock ring 244 to the hair care appliance 200 and to maintain the release mechanism 220 in an operable position for rotation. The projecting tabs 246 also include the slots 242 into which engagement features 234 on the second collar 232 of the attachment coupling 212 are configured to be received as the attachment is mated with the hair care appliance 200. An additional set of protrusions 216 (see FIG. 8B) on the second collar 232 that are co-located with the pins 230 of the attachment coupling 212 are configured to be received within respective slots 248 formed on the surface of the electrical connectors 224 to provide additional stability when the attachment is secured to the hair care appliance 200.
[0098] The attachment mating assembly 202 also includes a compression spring 250 (see FIG. 9) or other force generating element provided in a channel 252 formed within the housing 260 of the hair care appliance 200. The compression spring 250 is configured to be compressed within the channel 252 as a user rotates the release mechanism 220 to detach the attachment coupling 212 (and thus the attachment that includes the attachment coupling 212) from the hair care appliance 200. The spring 250 is configured to engage the protrusion 240 of the release mechanism 220 at a first end of the spring 250 and a terminal end of the channel 252 at a second, opposite end of the spring 250. The compression spring 250 is configured to extend against the terminal end of the channel 252 and exert force against the release mechanism protrusion 240 responsive to a user releasing the release mechanism 220, thereby causing the release mechanism 220 to return or reset to a position ready for receiving an attachment, which can be either the same attachment as just released or a different attachment.
[0099] When an attachment is secured to the hair care appliance 200, the second element 238 of the pair of engagement features 234 on the second side of the attachment coupling 212 are configured to engage with the protrusions 240 on the release mechanism 220. For example, the angle-faced portions of the second features 238 are oriented in correspondence with the angled faces on the protrusions 240 of the release mechanism 220. The release mechanism 220 is configured to rotate slightly, by way of movement of the compression spring 250, to enable the corresponding angled faces of the second features 238 of the attachment coupling 212 to engage with the protrusions 240 of the release mechanism 220. The first features 236 of the pair of engagement features on the second side of the attachment coupling 212 are configured to engage with a non-angled face of the release mechanism protrusion 240 to prevent rotation of the attachment within the attachment mating assembly 202. In this way, the release mechanism 220 is configured to securely fix the attachment to the hair care appliance 200 by linearly connecting the attachment coupling 212 to the attachment mating assembly 202.
[0100] The attachment mating assembly 202 is configured to receive the attachment coupling 212 therein and bring the electrical connectors 224 of the attachment mating assembly 202 into contact with the corresponding electrical connectors 222 of the attachment coupling 212 as shown in the cross-sectional view of FIG. 10. As further shown in FIG. 10, the body 260 of the hair care appliance 200 includes a frame 254 therein. The frame 254 includes a lumen 256 therein extending along a length of the frame 254. A fluid flow path 258 (shown as a dotted line) extends through the lumen 256 of the frame 254.
[0101] FIG. 11 illustrates another exemplary embodiment of a hair care appliance 300 having an attachment mating assembly 302 configured to couple to an attachment such as a brush attachment, a curling attachment, a concentrator attachment, or other type of attachment. The hair care appliance 300 is generally configured and used similar to the hair care appliance 200 of FIGS. 6-10 and is thus not particularly described again, e.g., the hair care appliance 300 includes a housing 306 (also see FIG. 14) , an air outlet 308 (also see FIGS. 12, 14, and 15) , and other elements such an air inlet, a user interface, a motor, a handle, a fan assembly, etc. For clarity of illustration, only a distal portion of the hair care appliance 300 is shown in FIG. 11, and only an attachment coupling 304 of the attachment is shown in FIG. 11. FIGS. 11-13, 16, and 17 show the attachment coupling 304 and the hair care appliance 300 coupled together. FIG. 15 shows the attachment coupling 304 and the hair care appliance 300 decoupled but rotationally aligned with one another for releasable mating. FIG. 14 shows the hair care appliance 300 as a standalone element. FIGS. 18-20 show the attachment coupling 304 as a standalone element.
[0102] As discussed further below, the hair care appliance 300 is configured to couple to the attachment that includes the attachment coupling 304 so that the hair care appliance 300 and the attachment are in electrical communication. The attachment of the hair care appliance 300 and the attachment is configured to automatically establish an electrical connection between the hair care appliance 300 and the attachment and thus automatically allow electronic communication between the hair care appliance 300 and the attachment, which as discussed herein allows power to be provided from the hair care appliance 300 to the attachment and allows data signals to be conveyed between the hair care appliance 300 and the attachment. A user does not need to take any special action to establish the electrical connection between the hair care appliance 300 and the attachment beyond merely attaching the attachment to the hair care appliance 300, which the user must do in ordinary course to use the attachment with the hair care appliance 300. Similarly, user detachment of the attachment from the hair care appliance 300 is configured to automatically cease the electrical connection between the hair care appliance 300 and the attachment. A user thus does not need to take any special action to electrically decouple the hair care appliance 300 and the attachment beyond merely detaching the attachment from the hair care appliance 300, which the user must do in ordinary course to use another attachment with the hair care appliance 300.
[0103] The attachment mating assembly 302 is configured to be coupled to the attachment coupling 304 of the attachment. The attachment mating assembly 302 is provided at a distal end of the housing 306 of the hair care appliance 300 and surrounds the air outlet 308.
[0104] The attachment mating assembly 302 is in the form of a ring-shaped body having mating features thereon. While various mating features can be utilized to mate the attachment mating assembly 302 to the attachment coupling 304, in the illustrated embodiment the attachment mating assembly 302 includes a plurality of projections (obscured in the figures) extending distally. The plurality of projections are configured to each extend into one of a plurality of slots 310 formed in a proximal end of the attachment coupling 304. As shown in FIGS. 15, 18, and 20, the slots 310 in this illustrated embodiment are recessed grooves formed in an exterior sidewall of the attachment coupling 304 and are therefore visible to a user. The slots 310 being visible to a user allows the slots 310 to serve as a visual guide to the user for proper alignment of the attachment relative to the hair care appliance 300 when coupling together the attachment and the hair care appliance 300.
[0105] The plurality of projections extend from a sidewall of a channel that extends around a perimeter of the attachment mating assembly 302, which is a substantially circular circumference of the substantially circular-shaped attachment mating assembly 302 in this illustrated embodiment. The attachment coupling 304 is configured to be coupled to the attachment mating assembly 302 by aligning the projections with the slots 310 and applying a linear force along a longitudinal axis of the attachment and the hair care appliance 300. No rotational force is or needs to be applied to achieve the coupling of the attachment mating assembly 302 and the attachment coupling 304, which may help ensure that the coupling occurs since the coupling is not dependent on a user rotating the attachment and / or the hair care appliance 300 at least by a certain amount.
[0106] The projections are operatively coupled to a lock 312 of the hair care appliance 300, shown in FIG. 14. The lock 312 is configured to be actuated by a user to facilitate secure coupling of the attachment to the hair care appliance 300 (lock 312 in a locked position) and release of the attachment from the hair care appliance 300 (lock 312 in an unlocked position) .
[0107] In this illustrated embodiment, the lock 312 is in the form of a latch that is operatively coupled to the plurality of projections. The latch 312 is received and movable within a latch opening 314 that is formed through a sidewall of the housing 306 so as to allow a user to access the latch 312. The latch 312 is configured to translate in back and forth within the latch opening 314. The latch 312 is shown in FIG. 14 positioned in a first position at a first end of the latch opening 314. The latch 312 is configured to be moved from the first position to a second position at a second end of the latch opening 314, opposite the first end of the latch opening 314. The latch 312 is also configured to move from the second position, which in an unlocked position, to the first position, which is a locked position. The latch 312 is operatively coupled to a spring (obscured in FIG. 14) . The spring is configured to bias the latch 312 towards the first position. Thus, when the lock 312 moves from the first position to the second position, the spring is configured to automatically urge the lock 312 back to the first position and thus ready the hair care appliance 300 for attachment to an attachment, which can be either the same attachment that was last attached to the hair care appliance 300 or a different attachment.
[0108] The actuation of the lock 312 is configured to move the projections relative to the housing 306. The projections are configured to be moved from an extended configuration to a retracted configuration by moving the latch 312. In the extended configuration, which corresponds to the first position of the lock 312, the projections extend distally so as to allow the projections to engage the slots 310 of the attachment coupling 304. In the retracted configured, which corresponds to the second position of the lock 312, the projections are retracted proximally from their positions in the extended configuration so as to allow the projections to disengage the slots 310 of the attachment coupling 304. Thus, actuating the latch 312 with the attachment coupled to the hair care appliance 300, e.g., with the attachment mating assembly 302 coupled with the attachment coupling 304, is configured to disengage the projections from the slots 310 and thereby allow the attachment to be removed from the hair care appliance 300.
[0109] The slots 310 and projections are configured to cooperate to help ensure that the attachment and the hair care appliance 300 are locked together and thus help ensure the electrical connection is properly established between the attachment and the hair care appliance 300 when the attachment and the hair care appliance 300 are attached together. If the projections are not aligned with the slots 310, the attachment cannot be locked to the hair care appliance 300 since the projections will be unable to move from the retracted configuration (lock 312 in the second, unlocked position) to the extended configuration (lock 312 in the first, locked position) .
[0110] The slots 310 and projections are also configured to cooperate to help ensure that the electrical connection is properly established between the attachment and the hair care appliance 300 when the attachment and the hair care appliance 300 are attached together because with the slots 310 aligned with and seating the projections, a plurality of electrical connectors 316 of the attachment mating assembly 302 will be aligned with and electrically connected with a plurality of electrical connectors 318 of the attachment coupling 304. In an exemplary embodiment at least two pairs of electrical connectors 316, 318 are used. In other embodiments, the attachment mating assembly 302 can include a single electrical connector 316 and the attachment coupling 304 can include a single electrical connector 318.
[0111] As shown in FIGS. 12, 13, 15, and 17, the plurality of electrical connectors 316 of the attachment mating assembly 302 includes a first plurality of electrodes 316 in the form of conductive plates, e.g., copper plates or other metallic plates. As shown in FIGS. 12, 15, and 18-20, the plurality of electrical connectors 318 of the attachment coupling 304 includes a second plurality of electrodes 318 in the form of conductive springs. FIG. 21 shows one electrical connector 318 of the attachment coupling 304 as a standalone element. As discussed further below, the first plurality of electrodes 316 are configured to engage the second plurality of electrodes 318 with the attachment attached to the hair care appliance 300 and thus allow electrical communication between the attachment and the hair care appliance 300. The first and second plurality of electrodes 316, 318 are configured to automatically electrically couple in response to the attachment being attached to the hair care appliance 300. FIG. 16 illustrates electrical connections 320 between the first and second plurality of electrodes 316, 318 with the attachment coupling 304 coupled to the attachment mating assembly 302. As also shown in FIG. 16, there are five pairs of electrical connectors 316, 318 in this illustrated implementation, e.g., five first plurality of electrodes 316 and five second plurality of electrodes 318, but another number of electrical connectors can be used, as mentioned above.
[0112] In this illustrated embodiment, the attachment, e.g., the attachment coupling 304 of the attachment, includes a PCB 322 (see FIG. 12) operatively coupled to the second plurality of electrodes 318. The electrical communication between the attachment and the hair care appliance 300 allows the PCB 322 to be powered with power provided to the attachment from the hair care appliance 300, allows data signals to be transmitted from the PCB 322 to the hair care appliance 300 (e.g., to electrical components of the hair care appliance 300, such as a PCB of the hair care appliance 300) , and allows data signals to be transmitted from the hair care appliance 300 (e.g., from electrical components of the hair care appliance 300, such as a PCB of the hair care appliance 300) to the PCB 322. In some embodiments, data flow is bidirectional with the hair care appliance 300 being configured to transmit data signals to the attachment and the attachment being configured to transmit data signals to the hair care appliance 300. In other embodiments, data flow is unidirectional with the hair care appliance 300 being configured to transmit data signals to the attachment or with the attachment being configured to transmit data signals to the hair care appliance 300. Data signals may not need to be provided to the attachment, for example, if the attachment does not have an on-board PCB configured to control one or more aspects of the attachment. Data signals may not need to be provided to the hair care appliance 300, for example, if the attachment does not include any sensors monitoring any parameters.
[0113] The electrical connectors 316, 318 of the attachment mating assembly 302 and the attachment coupling 304 are generally configured and used similar to the electrical connectors 222, 224 of FIG. 7 discussed above. Similar to the description above with reference to the electrical connectors 222, 224 of FIG. 7, the electrical connectors 316 of the hair care appliance 300 and corresponding electrical connectors 318 of the attachment are configured to be communicatively coupled via wiring 324 (see FIGS. 11, 13, 15, and 17) of the hair care appliance 300 to electrical components of the hair care appliance 300, e.g., a PCB, a fan assembly, a motor, a user interface, a switch, etc.
[0114] The electrical connectors 318 of the attachment coupling 304 are springs, as mentioned above, and are thus configured as having elasticity and an ability to bend. The electrical connectors 318 being configured to bend allows the electrical connectors 318 to move in response to the attachment coupling 304 of the attachment being coupled to the attachment mating assembly 302 of the hair care appliance 300. The movement of the electrical connectors 318 may help establish interference touch between the electrical connectors 318 of the attachment coupling 304 and the electrical connectors 316 of the attachment mating assembly 302 and thus help establish tight electrical connections 320.
[0115] The electrical connectors 318 of the attachment coupling 304 are biased radially outwardly. The electrical connectors 316 of the attachment mating assembly 302 are located radially outwardly of the electrical connectors 318 of the attachment coupling 304 with the attachment coupling 304 coupled to the attachment mating assembly 302, as shown in FIG. 12. The electrical connectors 318 of the attachment coupling 304 are thus configured to flex dynamically in a radially outward direction D1 toward the electrical connectors 316 of the attachment mating assembly 302 to help establish the interference touch between the electrical connectors 316, 318.
[0116] As shown in FIG. 12, the radially outward direction D1 in which the electrical connectors 318 of the attachment coupling 304 are biased is substantially perpendicular to a longitudinal axis A1 of the hair care assembly including the hair care appliance 300 and the attachment releasably attached to the hair care appliance. In the view of FIG. 12, the radially outward direction D1 is a horizontal direction and the longitudinal axis A1 extends in a vertical direction. The longitudinal axis A1 of the hair care assembly is also the longitudinal axis of the hair care appliance 300 (at least distal to a rotational hinge joint in embodiments in which the hair care appliance 300 includes a rotational hinge joint about which the hair care appliance 300 can move between straight and angled configurations) and the longitudinal axis of the attachment releasably attached to the hair care appliance. As discussed above, the attachment coupling 304 is configured to be coupled to the attachment mating assembly 302 by applying a linear force along the longitudinal axis A1 of the attachment and the hair care appliance 300. The direction D1 of dynamic flexing of the electrical connectors 318 of the attachment coupling 304 is thus substantially perpendicular to a direction of the force applied to releasably attach the attachment and the hair care appliance 300. The force applied to releasably attach the attachment and the hair care appliance 300 will therefore not counteract the dynamic flexing of the electrical connectors 318 of the attachment coupling 304.
[0117] As shown in FIG. 12, the electrical connectors 316 of the hair care appliance 300 extend substantially parallel to the longitudinal axis A1. Thus, in the view of FIG. 12, the electrical connectors 316 of the hair care appliance 300 extend in the vertical direction. Since the force applied to releasably attach the attachment and the hair care appliance 300 is substantially perpendicular to the longitudinal axis A1, e.g., is applied in the vertical direction, the electrical connectors 318 of the attachment will slide along their respective ones of the electrical connectors 316 of the hair care appliance 300 substantially parallel to the longitudinal axis A1, e.g., slide vertically, as the attachment and the hair care appliance 300 are releasably attached together. The force applied to releasably attach the attachment and the hair care appliance 300 in the vertical direction will therefore not counteract the dynamic flexing of the electrical connectors 318 of the attachment coupling 304 in the horizontal direction.
[0118] As shown in FIGS. 18, 19, and 21, each of the electrical connectors 318 of the attachment coupling 304 includes a protruding portion 318a and a longitudinally extending portion 318b. The protruding portion 318a protrudes radially outward in the radially outward direction D1. The protruding portion 318a of the electrical connector 318 is the portion of the electrical connector 318 configured to contact the electrical connector 316 of the hair care appliance 300. The longitudinal extending portion 318b extends substantially along the longitudinal axis A1 and is located radially inward of the protruding portion 318a. The longitudinal extending portion 318b extends to and is connected to the PCB 322, as shown in FIGS. 12 and 19, to electrically connect the electrical connector 318 to the PCB 322.
[0119] The arrangement of the electrical connectors 316, 318 can vary. In this illustrated embodiment, the electrical connectors 318 of the attachment coupling 304 are positioned about a perimeter of the attachment coupling 304, which is around the circumference of the substantially circular-shaped attachment coupling 304 in this illustrated embodiment. The electrical connectors 318 of the attachment coupling 304 are positioned about a perimeter of the attachment coupling 304 in alignment with the PCB 322 so that the longitudinal extending portions 318b of the electrical connectors 318 each extend to the PCB 322. The electrical connectors 318 of the attachment coupling 304 are thus all in a same half of the perimeter of the attachment coupling 304 in this illustrated embodiment, as shown in FIG. 16. The electrical connectors 316 of the hair care appliance 300 are arranged similarly to the electrical connectors 318 of the attachment coupling 304 to allow for the electrical connections 320 to be established.
[0120] The attachment coupling 304 includes a body 326, a bracket 328, and a support 330. The body 326 is a ring-shaped structure, and the bracket 328 and the support 330 are each C-shaped structures, as shown in FIGS. 22-24. The bracket 328 and the support 330 are fixedly secured to the body 326 in this illustrated embodiment. The body 326, the bracket 328, and the support 330 being separate components that are fixed together during manufacturing, as in this illustrated embodiment, may simplify manufacturing as compared to the body 326, the bracket 328, and the support 330 each being a singular component. However, in some embodiments, two or more of the body 326, the bracket 328, and the support 330 are a singular, integral component.
[0121] The body 326 includes the exterior sidewall in which the slots 310 are formed, as shown in FIGS. 15, 18, and 20. The exterior sidewall of the body 326 includes a plurality of openings 332 through which the plurality of electrical connectors 318 of the attachment coupling 304 are configured to extend, as shown in FIG. 18. In particular, the protruding portions 318a of the electrical connectors 318 extend through the openings 332 formed in the body 326. The protruding portions 318a of the electrical connectors 318 are thus the portions of the electrical connectors 318 exposed to the electrical connectors 316 of the attachment mating assembly 302 for electrical connection with the electrical connectors 316 of the attachment mating assembly 302. The body 326 and the bracket 328 cooperate to separate a remainder of the electrical connectors 318 of the attachment coupling 304 from coming into contact with the electrical connectors 316 of the attachment mating assembly 302. Additionally, the body 326 and the bracket 328 cooperate to prevent rotation of the electrical connectors 318 of the attachment coupling 304 and to structurally limit the dynamic bending of the electrical connectors 318 of the attachment coupling 304, which may help ensure secure electrical connections 320.
[0122] The bracket 328 is fixedly secured to the PCB 322 and to the electrical connectors 318 of the attachment coupling 304. The bracket 328 may thus help ensure a secure electrical connection between the PCB 322 and the electrical connectors 318 of the attachment coupling 304.
[0123] The bracket 328 is also fixedly secured to the support 330 to help secure the bracket 328 in position relative to the body 326 and thus secure the electrical connectors 318 of the attachment coupling 304 in position relative to the body 326. The support 330 is also fixedly secured to a grate cover 334 at an air outlet 336 of the attachment coupling 304 that is configured to be positioned distal to the air outlet 308 of the hair care appliance 300 with the attachment coupling 304 coupled to the attachment mating assembly 302.
[0124] As shown in FIGS. 15 and 17, the electrical connectors 316 of the hair care appliance 300 are each attached at a distal end of the electrical connector 316 to a distal collar 338 of the attachment mating assembly 302 and at a proximal end of the electrical connector to a proximal collar 340 of the attachment mating assembly 302. The distal and proximal collars 338, 340 are each ring-shaped. With the attachment mating assembly 302 releasably attached to the attachment coupling 304, the distal collar 338 of the hair care appliance 300 is configured to abut the body 326 of the attachment. The first and second electrical connectors 316, 318 can thus be located in an interior of the hair care assembly that includes the hair care appliance and the attachment to help protect the first and second electrical connectors 316, 318.
[0125] FIGS. 25 and 26 illustrate another exemplary embodiment of a hair care appliance 400 having an attachment mating assembly 402 configured to couple to an attachment such as a brush attachment, a curling attachment, a concentrator attachment, or other type of attachment. The hair care appliance 400 is generally configured and used similar to the hair care appliance 200 of FIGS. 6-10 and is thus not particularly described again, e.g., the hair care appliance 400 includes a housing 406, an air outlet 408 (also see FIG. 27) , and other elements such an air inlet, a user interface, a motor, a handle, a fan assembly, etc. For clarity of illustration, the hair care appliance 400 is only partially shown in FIGS. 25-27, and only portions of an attachment coupling 404 of the attachment are shown in FIGS. 25-27. FIGS. 25-27 show the attachment coupling 404 and the hair care appliance 400 coupled together. FIGS. 28 and 29 show the attachment coupling 404 as a standalone element.
[0126] The attachment mating assembly 402 of the hair care appliance 400 is generally configured and used similar to the attachment mating assembly 302 of the hair care appliance 300 of FIG. 11 and is thus not particularly described again, e.g., the attachment mating assembly 402 includes a lock, a plurality of electrical connectors 416 in the form of metal plates, a plurality of protrusions, and wiring 424.
[0127] The attachment coupling 404 of the attachment is generally configured and used similar to the attachment coupling 304 of FIG. 11 and is thus not particularly described again, e.g., the attachment coupling 404 includes a plurality of slots 410 formed in a proximal end of the attachment coupling 404, a plurality of electrical connectors 418 in the form of springs, a PCB 422, a bracket 428, a support 430, a body 426 having a plurality of openings 432, and a grate cover 434 at an air outlet 436 of the attachment coupling 404. The slots 410 in this illustrated embodiment have a different shape than the slots 310 of the embodiment of FIG. 15.
[0128] In this illustrated embodiment the attachment mating assembly 402 includes five electrical connectors 416 and the attachment coupling 404 includes five electrical connectors 418. FIG. 26 illustrates electrical connections 420 between the first and second plurality of electrodes 416, 418 with the attachment coupling 404 coupled to the attachment mating assembly 402 and protruding portions 418a of the attachment coupling’s electrodes 418 touching respective ones of the electrodes 416 of the attachment mating assembly 402.
[0129] One exemplary embodiment of an attachment configured for use with a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and an attachment mating assembly (e.g., the attachment mating assembly 202 of FIG. 7, the attachment mating assembly 302 of FIG. 11, the attachment mating assembly 402 of FIG. 25, or other attachment mating assembly) described herein includes a curling attachment. One exemplary embodiment of a curling attachment is shown in FIG. 6 and is configured and used similar to another exemplary embodiment of a curling attachment 500 is shown in FIG. 30. The curling attachment 500 includes an elongate body 502 extending between an attachment end 504 and a distal end 506. The attachment end 504 is configured to mate or couple with a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) via an attachment coupling 514 (e.g., the attachment coupling 212 of FIGS. 7-10, the attachment coupling 304 of FIG. 11, the attachment coupling 404 of FIG. 25, or other attachment coupling) as described herein. The distal end 506 includes an end cap 508 having a cylindrical or other-shape protrusion extending away from an end plate 510 of the end cap 508 as shown in FIG. 31. The end plate 510 has a diameter that is greater than a diameter of the body 502 to protect a user’s fingers from the heated surfaces of the body 502 when grasping the curling attachment 500 at the distal end 506.
[0130] As also shown in FIGS. 31-34, the attachment 500 includes wiring 512 configured to mate a plurality of electrical connectors of the attachment coupling 514 with electrical components of the curling attachment 500, such as LEDs (and / or other types of lights) , sensors, haptic feedback mechanisms, PCB, etc. The LEDs (and / or other types of lights) , sensors, haptic feedback mechanisms, PCB, etc. in the attachment 500 are configured to provide user feedback regarding operation of the attachment 500. In some embodiments, the user feedback can be visual, audible, and / or tactile feedback. For example, a haptic feedback mechanism can be configured to generate vibrations which can be sensed by a user with accessibility requirements. In some embodiments, a motor of the hair care appliance to which the attachment 500 is coupled can be configured to generate haptic feedback. In some embodiments, the wiring 512 may be completely enclosed within the curling attachment 500. In some embodiments, the wiring 512 is omitted, such as in the attachment couplings 304, 404 of FIGS. 11 and 25 in which the plurality of electrical connectors 318, 418 directly connect to the PCB 322, 422.
[0131] The curling attachment 500 includes a plurality of longitudinally arranged plates 516 that are configured to be heated and form a curl in hair when the heated plates 516 are contacted with hair. Air flow is configured to be received from the hair care appliance to which the curling attachment 500 is attached via an inlet 518 of the curling attachment 500 and pass through the body 502 of the curling attachment 500. Air flow is configured to exit the curling attachment 500 via outlets 520 arranged longitudinally along the body 502 in between adjacent plates 516. Air flow exiting tangentially to the surface of the curling attachment 500 is configured to induce a Coanda effect. The Coanda effect allows hair to wrap around the external surface of the curling attachment 500 without a user directly manipulating hair onto the heated curling attachment 500.
[0132] The curling attachment 500 also includes a heater 522, as shown in FIGS. 31 and 32. The heater 522 in this illustrated embodiment is in the form of a cylindrical or rod-shaped heater, such as a cartridge heater, arranged within an inner lumen of a heater frame 524. The heater 522 extends along the lumen for the entire length of the body 502 or partially within the lumen at one or more portions of the body 502. The heater frame 524 includes a thermally conductive material, such as metal. In some embodiments the plates 516 can further include a coating on a surface of each plate 516 to aid heat retention and distribution. The end cap 508 is coupled to the heater frame 524. The combination of the airflow and the heater 522 configured within the curling attachment 200 allows a user to obtain the benefits of conductive thermal curling with auto-wrapping hair around a heated hair care appliance.
[0133] As shown in FIG. 33, the heater frame 524 includes a plurality of arms 526 that extend radially from a central longitudinal axis of the heater frame 524. As in this illustrated embodiment, a plate 516 can be integrally formed with each arm 526 and can have a curved profile forming a circumference of the curling attachment 500. The number of arms 526 and plates 516 can vary and may not be limited to the number of arms 526 and plates 516 shown in FIG. 33. The heater frame 524 can be formed via extrusion for efficient manufacturing.
[0134] The heater frame 524 also includes a plurality of flow path tunnels 528 formed between adjacent arms 526 of the heater frame 524 and bounded circumferentially by the plates 516. The flow path tunnels 528 extend longitudinally along the length of the body 502 and include a flow path lumen 530 therein. A conduit 532 is arranged within the flow path lumen 530 as shown in FIG. 34. The conduit 532 includes a heat resistant material. The conduit 532 is configured to guide air flow from the inlet 518 to the outlets 520 via vanes 534 formed on an inner surface of the conduit 532. The conduit 532 has longitudinal openings at which the outlets 520 of the curling attachment 500 are formed adjacent to longitudinal edges of respective plates 516 of the heater frame 524. For ease of manufacture, the conduit 532 can be inserted into the flow path tunnels 528 of the heater frame 524.
[0135] The curling attachment 500 also includes a moisture sensor 536 configured to detect an amount of moisture in hair of a user using the attachment 500. One moisture sensor 536 is shown in FIG. 34, but in some embodiments, the curling attachment 500 can include more than one moisture sensor 536. As shown in this illustrated embodiment of FIG. 34, the moisture sensor 536 can be positioned between the conduit 532 and the plate 516. In some embodiments, the moisture sensor 536 can extend the entire length of the body 502 or partially within the body 502. In some embodiments, the moisture sensor 536 can include a capacitive moisture sensor. The moisture sensor 536 is configured to be communicatively coupled, via the attachment coupling 514, to other electrical components of the hair care appliance to which the curling attachment 500 is attached. Sensed data obtained by the moisture sensor 536 is configured to be provided to a microprocessor or controller of the hair care appliance to which the curling attachment 500 is attached and is configured to be used by the microprocessor or controller of the hair care appliance to control operation of the hair care appliance. For example, in some embodiments, the hair care appliance can be configured to perform predetermined heating and / or drying (e.g., air flow) operations based on the amount of moisture determined from the sensor data obtained via the moisture sensor 536.
[0136] Another exemplary embodiment of an attachment configured for use with a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and an attachment mating assembly (e.g., the attachment mating assembly 202 of FIG. 7, the attachment mating assembly 302 of FIG. 11, the attachment mating assembly 402 of FIG. 25, or other attachment mating assembly) described herein includes a concentrator attachment. One exemplary embodiment of a concentrator attachment 600 is shown in FIG. 35 and includes a heating element 602. The heating element 602 is configured to be communicatively coupled to electrical components of the hair care appliance to which the concentrator attachment 600 is attached via electrical connectors of the concentrator attachment’s attachment coupling 604 (e.g., the attachment coupling 212 of FIGS. 7-10, the attachment coupling 304 of FIG. 11, the attachment coupling 404 of FIG. 25, or other attachment coupling) described herein. In this way, the heating element 602 is configured to provide additional heat to air flow output at an outlet 606 of the concentrator attachment 600 and in close proximity to the hair for improved styling effects.
[0137] In some embodiments, an attachment can include an ionizer therein. The ionizer can be positioned in the attachment to maximize the amount of ions received by the hair. The ionizer is configured to be communicatively coupled to electrical components of the hair care appliance to which the attachment is attached via electrical connectors of the attachment’s attachment coupling described herein. As shown in FIG. 35, the illustrated embodiment of the concentrator attachment 600 includes an ionizer 608 positioned within the outlet 606.
[0138] In some embodiments, an attachment can include one or more torque sensors therein. The torque sensors can be configured with respect to bristles, such as bristles 704 of a brush attachment 700, as shown in FIG. 36. The brush attachment 700 is another exemplary embodiment of an attachment configured for use with a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and an attachment mating assembly (e.g., the attachment mating assembly 202 of FIG. 7, the attachment mating assembly 302 of FIG. 11, the attachment mating assembly 402 of FIG. 25, or other attachment mating assembly) described herein. The torque sensors (e.g., torque sensors 702 of the brush attachment 700, or other torque sensors of another attachment) are configured to be coupled to electrical components of a hair care appliance to which an attachment including the torque sensors is attached via electrical connectors of the attachment’s attachment coupling described herein. The torque sensors are configured to generate sensor data associated with an amount of torque applied to at least one bristle or group of bristles as a user uses the attachment, e.g., brushes hair using the brush attachment 700. The amount of torque is associated with a condition of the hair and an operating parameter of the hair care appliance can thus be determined. For example, the torque sensor data can be used to determine whether the user has dry or tangled hair based on elevated torque values indicating more force is required to brush the dry or tangled hair. Lower torque values are associated with wet, oily, or fine hair indicating less force is required to brush the hair. The hair care appliance to which the attachment is attached as described herein can be configured to adjust one or more of a heating temperature or an air flow setting based on the sensed torque data.
[0139] Styling hair can require specific skills and hair treatments to achieve a desired style. Some users may lack particular skill necessary to utilize a hair care appliance to achieve their desired style. Thus, it can be desirable for a hair care appliance and / or attachment to provide user feedback and / or automated styling assistance. For example, Coanda curling is a particular method of curling hair that can be difficult to master. A user is required to use a curling attachment, e.g., the curling attachment 204 of FIG. 6, the curling attachment 500 of FIG. 30, or other curling attachment, that automatically wraps hair around a curler by creating an airflow that pulls hair into place around the heated plates of the curling attachment. After the hair is wrapped around a body of a curling attachment, the user then heats the hair for a set period of time, before cooling the hair for a set period of time to implement the curl in the hair. A user may not know where to contact the hair on the attachment, have difficulty performing the styling for the required time periods or lose track of time, or have difficulty performing the styling while looking at their reflection in a mirror.
[0140] The hair care appliance and powered attachments described herein can remedy these problems by acquiring data about the user’s hair and providing feedback to the user as they style their hair. The feedback can ensure best practices associated with a particular styling technique, are communicated to the user. The feedback can be provided via visual, audio, and / or haptic feedback mechanisms provided in the powered attachments described herein. The electrical coupling enabled between attachments and the hair care appliance herein can provide a robust array of feedback and operation modes to improve a user’s experience and produce improved, long-lasting styling effects.
[0141] For example, in one embodiment shown in FIG. 37, a user can operate a hair care appliance 800 (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and a powered curling attachment 802 (e.g., the curling attachment 204 of FIG. 6, the curling attachment 500 of FIG. 30, or other curling attachment) as described herein in a manual mode of operation. As shown in FIG. 37, a user can activate a manual actuator 804 (shown as a switch in this illustrated embodiment) of the hair care appliance 800, with the hair care appliance 800 attached to the powered curling attachment 802, to initiate a timed program for curling hair. The switch 804 is configured to be communicatively coupled via electrical connectors of the curling attachment’s attachment coupling to the curling attachment 802, which can include user interfaces such as an LED 806 and an audio output 808 as shown in this illustrated embodiment. The switch 804 is further configured to be communicatively coupled to electrical components of the hair care appliance 800, which can include user interfaces (e.g., an LED 810 and an audio output 812) as shown in this illustrated embodiment, heaters 814, a motor 816, a microprocessor and / or controller 818 coupled to a memory storing non-transitory computer-executable instructions associated with one or more operating parameters and / or modes of operation of the hair care appliance 800 (e.g., “software control” ) .
[0142] Activating the manual switch 804 is configured to turn on the hair care appliance 800, and a user can wrap their hair around the curling attachment 802 attached to the hair care appliance 800. A user can then manually actuate a timing actuator, e.g., press a timing starter of the hair care appliance’s user interface, to initiate a sequence of operational modes necessary to perform the curling. The software control is configured to generate control signals provided to various electrical components in the attachment 802 and the hair care appliance 800, such as the user interfaces 806, 808, 810, 812, heaters 814, or motor 816. The control signals are configured to initiate pre-determined timing cycles necessary to curl the hair. The control signals are further configured to cause one or more of the user interfaces 806, 808, 810, 812 to provide feedback to the user indicating a point at which the user should manually switch to the next stage of curling.
[0143] In some embodiments, a curling attachment is configured to provide sensor data from a moisture sensor of the curling attachment to control operation of the attachment and a hair care appliance to which the attachment is attached via software control of the hair care appliance. For example, as shown in FIG. 38, a user can turn on a hair care appliance 900 (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and wrap their hair around a curling attachment 902 attached to the hair care appliance 900. Moisture data determined from a moisture sensor 904 of the curling attachment 902 is configured to be used by software control 906 of the hair care appliance 900 to determine requirements for styling the moist hair. Based on detecting the moist hair wrapped around the curling attachment 902, the software control 906 is configured to initiate a timing program cycling through pre-determined timing cycles.

For example, as shown in one embodiment in FIG. 39, a user can turn on a hair care appliance 1000 (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and wrap their hair around a curling attachment 1002 releasably attached to the hair care appliance 1000. Moisture data determined from a moisture sensor 1004 of the curling attachment 1002 is configured to be used (e.g., by software control 1006 of the hair care appliance 1000) to determine requirements for styling the moist hair. Based on detecting the moist hair wrapped around the curling attachment 1002, the software control 1006 is configured to initiate a gradually progressive heating program. When the moisture data indicates a predetermined level of moisture, the software control 1006 is configured to generate control signals to cause a heater 1008 and a motor 1010 of the hair care appliance 1000 to generate a short blast of hotter air for a predetermined period. Continuing to sense the moist hair, the software control 1006 is configured to cause the heater 1008 and the motor 1010 to generate cool air for a subsequent predetermined period of time. Responsive to sensing the appropriate moisture level and completion of previous predetermined periods of treatment, the software control 1006 is configured to cause the hair care appliance 1000 to shut off. FIG. 20 also shows an LED 1012 of the attachment 1002, an audio output 1014 of the attachment 1002, an LED 1016 of the hair care appliance 1000, and an audio output 1018 of the hair care appliance 1000 configured to provide information to the user, as discussed herein.
[0145] In some embodiments, a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) and powered attachments (e.g., the attachment 204 of FIG. 6, the attachment 500 of FIG. 30, the attachment 600 of FIG. 35, the attachment 700 of FIG. 36, the attachment 802 of FIG. 37, the attachment 902 of FIG. 38, or other attachment) described herein is configured to perform pre-determined timing cycles associated a variety of styling methods and / or attachment usage. For example, as shown in FIG. 40, one embodiment of a plot of temperature settings and corresponding timing is provided that can be executed by software control configured in a hair care appliance (e.g., the hair care appliance 100 of FIGS. 1-5, the hair care appliance 200 of FIGS. 6-10, the hair care appliance 300 of FIG. 11, the hair care appliance 400 of FIG. 25, or other hair care appliance) in regard to curling hair via a curling attachment (e.g., the curling attachment 204 of FIG. 6, the curling attachment 500 of FIG. 30, the curling attachment 802 of FIG. 37, the curling attachment 902 of FIG. 38, or other curling attachment) . An initial stage 1 can be assumed to correspond to the hair care appliance being shut off. Responsive to a user activating a switch of the hair care appliance, stage 2 “Warm-up” starts and last for about 5 seconds. During stage 2, the temperature of the heating element in the frame of the attachment, which is attached to the hair care appliance, initiates heating to cause heated plates of the attachment to heat to about 100 ℃. A first feedback indication associated with stage 2 can be provided to the user via a user interface of the attachment and / or the hair care appliance. In some embodiments, the first feedback indication includes a first color (e.g., of a light, etc. ) , a first sound, or the like.
[0146] Following stage 2, the hair care appliance enters stage 3 associated with a “Ready” stage in which the heated plates of the attachment are about 100 ℃.

In some embodiments, the second feedback indication can include a second color (e.g., of a light, etc. ) , a second sound, or the like that is different than the first feedback indication.
[0147] Responsive to manual activation or sensed moisture data obtained from hair wrapped around the attachment by a moisture sensor of the attachment at point 4, stage 5 commences for drying hair. During the “hair drying” stage 5, the heater of the attachment causes the heated plates of the attachment to heat to about 140 ℃ for a period of about 5 seconds to dry the moist hair. Also during this stage, the motor is activated to generate heated air flow via the heating element of the hair care appliance. The generated heated air flow is provided through the outlets of the attachment for drying the hair. A third feedback indication can be provided to the user via a user interface of the attachment and / or the hair care appliance. In some embodiments, the third feedback indication can include a third color (e.g., of a light, etc. ) , a third sound, or the like that is different than the first feedback indication and the second feedback indication.
[0148] Following stage 5, the hair care appliance enters stage 6, associated with provision of a “Hot Shot” volume of heated air for about 5-10 seconds. The heater of the attachment causes the heated plates to heat from about 140 ℃ to about 185 ℃, and the motor is activated to increase the velocity of the air heated via a heating element of the hair care appliance. A fourth feedback indication can be provided to the user via a user interface of the attachment and / or the hair care appliance. In some embodiments, the fourth feedback indication can include a fourth color (e.g., of a light, etc. ) , a fourth sound, or the like that is different than the first feedback indication, the second feedback indication, and the third feedback indication.
[0149] After completion of stage 6, a “Cool Shot” stage 7 is started. During stage 7, a volume of lower temperature air is provided for a period of about 10 seconds to set the curl. During this stage, the heater of the attachment is powered off so that the temperature of the heated plates drops from about 185 ℃ to about 30 ℃. In addition, the motor is activated to provide a volume of air at a reduced or ambient temperature via the heating element of the hair care appliance. A fifth feedback indication can be provided to the user via a user interface of the attachment and / or the hair care appliance. In some embodiments, the fifth feedback indication can include a fifth color (e.g., of a light, etc. ) , a fifth sound, or the like that is different than the first feedback indication, the second feedback indication, the third feedback indication, and the fourth feedback indication.
[0150] Following stage 7, the hair care appliance is configured to automatically shut down or otherwise enter a stand-by mode awaiting a next usage or input from a user as shown in stage 8 “Auto Shutdown” . A sixth feedback indication can be provided to the user via a user interface of the attachment and / or the hair care appliance. In some embodiments, the sixth feedback indication can include a sixth color (e.g., of a light, etc. ) , a sixth sound, or the like that is different than the first feedback indication, the second feedback indication, the third feedback indication, the fourth feedback indication, and the fifth feedback indication.
