[0044] Certain example embodiments will now be described to provide an overall understanding of the principles of 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 example embodiments and that the scope of the present application is defined solely by the claims. The features illustrated or described in connection with one example embodiment can be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present application.

[0045] Various example hair care appliances and accessories for use with hair care appliances are provided herein. Generally, the hair care appliances in the example embodiments are in the form of a hair dryer having an air inlet and at least one air outlet, as well as various internal components such as a fan, a motor, and a heater that facilitate use and operation of the hair care appliance. Various accessories (also referred to herein as "attachments") for use with a hair care appliance, such as a hair dryer, or with any other hair care appliance known in the art are also provided. The configuration of the appliance varies based on the type of accessory that is mated with the hair care appliance.

[0046] The hair care appliances and accessories described herein are configured to be coupled in a manner that places the hair care appliance and the accessory coupled to the hair care appliance in electrical communication. Power can be transmitted between the hair care appliance and the accessory coupled to the hair care appliance. In some embodiments, data signals can be transmitted between the hair care appliance and the accessory coupled to the hair care appliance. Conventional hair care appliances and their accessories can not have the ability to transmit power to an accessory coupled to the hair care appliance or to exchange data signals between the hair care appliance and the accessory. As a result, users can perform certain styling methods poorly, and the resulting hair style can be undesirable or unintended, resulting in a negative user experience. In contrast, the hair care appliances and accessories described herein can provide a more reliable styling experience by transmitting power and / or data signals between the hair care appliance and the accessory coupled thereto, such as by way of sensors, user interfaces, and programmable styling routines as described herein. The hair care appliances and accessories described herein can enhance the overall styling experience regardless of user skill, and provide a modular styling apparatus that can be adapted to various styling needs via a wide selection of accessories configured to be used with the hair care appliance.

[0047] With the attachment coupled to the hair care appliance, the user can receive an indication from the user interface of the attachment indicating feedback of at least one setting (e.g., timing, temperature, etc.) required to achieve an optimal styling result. In some embodiments, a powered sensor disposed in the attachment can further enable automatic operation of the hair care appliance to ensure that the user is using the device in a manner that will yield the best possible result for the desired styling method.

[0048] FIG. 1 and FIG. 2 An example embodiment of a hair care appliance 100 is illustrated. As shown, the illustrated hair care appliance 100 has a straight and a bent configuration, however the hair care appliance 100 can have various other configurations. As in the illustrated embodiment, the hair care appliance 100 can generally include a handle 110 movably coupled to a main body 120 by a rotary articulation joint 124. In the illustrated embodiment, the handle 110 and the main body 120 are each generally cylindrical in shape. The handle 110 has an inlet 112 at a first end of the appliance 100, and the main body 120 has an outlet 122 at a second end of the appliance 100. A fluid flow path P (shown in dashed lines) is formed between the inlet 112 and the outlet 122. The rotary articulation joint 124 formed between the handle 110 and the main body 120 is configured to be articulated via user operation to change the configuration of the hair care appliance 100 and the fluid flow path P from a straight configuration to a bent configuration (also referred to herein as an "angled configuration"). FIG. 1 In the illustrated straight configuration, the appliance 100 has an overall elongated cylindrical shape. The handle 110 has the inlet 112 at a first end of the appliance 100, and the main body 120 has the outlet 122 at a second end of the appliance 100. A fluid flow path P (shown in dashed lines) is formed between the inlet 112 and the outlet 122. The rotary articulation joint 124 formed between the handle 110 and the main body 120 is configured to be articulated via user operation to change the configuration of the hair care appliance 100 and the fluid flow path P from a straight configuration to a bent configuration (also referred to herein as an "angled configuration"). FIG. 2 As shown in the angled configuration, the handle 110 and the main body 120 are angled relative to one another as a result of the articulation of the rotary articulation joint 124. As a result, as shown in the angled configuration, the fluid flow path P is angled between the handle 110 and the main body 120. FIG. 2 As shown in the angled configuration, the handle 110 and the main body 120 are angled relative to one another as a result of the articulation of the rotary articulation joint 124. As a result, as shown in the angled configuration, the fluid flow path P is angled between the handle 110 and the main body 120. FIG. 1 In the straight configuration, the fluid flow path P is substantially straight from the inlet 112 to the outlet 122.

[0049] It will be appreciated by those skilled in the art that the hair care appliance 100 can be operated with the rotary articulation joint 124 unlocked, and / or with the rotary articulation joint 124 rotated to any position between the positions of the rotary articulation joint 124 in the straight configuration and the angled configuration. In other aspects, the hair care appliance 100 and the rotary articulation joint 124 can be configured to prevent over-rotation of the rotary articulation joint 124 beyond its position in the angled configuration. As shown in the straight configuration, the hair care appliance 100 can be configured in a fully straight configuration in which the rotary articulation joint locks the main body 120 in a manner that is substantially longitudinally aligned with the handle 110. As shown in the angled configuration, the hair care appliance 100 can be configured in a fully angled configuration in which the rotary articulation joint locks the main body 120 in a manner that is substantially transversely aligned with the handle 110. FIG. 1 As shown in the angled configuration, the handle 110 and the main body 120 are angled relative to one another as a result of the articulation of the rotary articulation joint 124. As a result, as shown in the angled configuration, the fluid flow path P is angled between the handle 110 and the main body 120. FIG. 2As shown, the hair care appliance 100 can be configured in a fully folded configuration in which the rotary articulation joint 124 angularly locks the body 120 relative to the handle 110. The hair care appliance 100 can also be configured in a rotated configuration in which the rotary articulation joint 124 positions the body 120 relative to the handle 110 in an angular range of positions between the straight configuration and the folded configuration. In FIG. 2 A fully angled configuration of the hair care appliance 100 is illustrated in the middle. In 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.

[0050] The hair care appliance 100 includes various internal electrical components 126 configured for operating the appliance 100. Generally, as in the illustrated embodiment, the handle 110 can include electrical components 126 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 the example embodiment, as shown, the fan assembly 128 is placed downstream of the rotary articulation joint 124 and proximate to the heater assembly 132, which is disposed upstream of the rotary articulation joint 124. This can help improve fluid flow within the hair care appliance 100. The fan assembly 128 is configured to create fluid flow along the fluid flow path P such that air is drawn into the inlet 112, through the handle 110, and into the body 120 to be expelled via the outlet 122. As the air passes through the body 120, the air is heated via the heater assembly 132.

[0051] The electrical components 126 are configured to be coupled to a power supply. FIG. 3 A power cord 130 extending from a proximal base of the handle 110 is illustrated. The power cord 130 has a terminal end (not shown) configured to be coupled to a power source, for example, the terminal end can be configured to be plugged into an electrical outlet. The power cord 130 includes internal electrical wiring configured to deliver electrical power to the electrical components 126 in the handle 110. The power cord 130 can be connected to an electronics housing containing the electrical components 126, as in the illustrated embodiment, which can include at least one controller or printed circuit board (PCB), as FIG. 4 shown.

[0052] As FIG. 3As further shown, the proximal base of the handle 110 includes a filter assembly 116 that is configured to filter air drawn in through the inlet 112. In the illustrated embodiment, the filter assembly 116 extends around the proximal end of the handle 110 but is not formed in the end wall of the handle 110. Thus, the fluid F is configured to be drawn in circumferentially around the side wall of the handle 110. The illustrated filter assembly 116 includes an inlet housing 140 that is generally C-shaped and is flexible to allow the inlet housing 140 to be removed for cleaning. In the illustrated embodiment, the user interface 138 intersects the inlet housing 140. The inlet housing 140 has a plurality of holes through which the fluid F is configured to flow into the fluid flow path P, and 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. FIG. 4 As shown, the filter 142 may be a porous element configured to block debris and hair that may have entered the inlet housing 140, thereby preventing the debris from entering the fluid flow path P. FIG. 4 As further shown, the electrical components 126 are positioned immediately downstream of the filter 142, but upstream of the fan assembly 128, so that when the fluid F is drawn toward and into the operating fan assembly 128, the fluid flow path P flows over and around the electrical components 126. This can help cool the electrical components 126.

[0053] The handle 110 also includes a user interface 138 that is configured to enable a user to provide input to operate the appliance 100, such as FIG. 5. In particular, as in the illustrated embodiment, the user interface 138 may include one or more actuators (e.g., buttons, switches, etc.) for turning the hair care appliance 100 on and off, adjusting the temperature setting of the heater assembly 132 (and thus adjusting the temperature of the fluid F heated by the heater assembly 132), and adjusting the fan speed of the fan assembly 128 (and thus adjusting the speed of the fluid F discharged via the outlet 122). The user interface 138 also includes one or more actuators for powering or otherwise controlling accessories 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 heater assembly 132, thereby providing cold, unheated fluid from the outlet 122. In some embodiments, the user interface 138 may include one or more light emitting diodes (LEDs) and / or other types of lights configured to provide a visual indication of the operating mode of the hair care appliance 100. In some embodiments, the user interface 138 may include one or more speakers configured to provide an audible indication of the operating mode of the hair care appliance 100. In some embodiments, the user interface 138 can include one or more tactile feedback mechanisms configured to provide a tactile indication of the operating mode of the hair care appliance 100 , such as vibration.

[0054] While the user interface 138 can be positioned at a variety of locations, in an exemplary embodiment, the user interface 138 extends longitudinally along at least a portion of the handle 110. FIG. 5 As shown, in this illustrated embodiment, the user interface 138 extends along the base of the handle 110, intersecting the filter assembly 116 in the illustrated manner, and extending toward the rotating hinge joint 124, terminating at a short distance from the rotating hinge joint 124. In this illustrated embodiment, the user interface 138 is disposed on a hemmed portion 136 of the handle 110. The hemmed portion 136 includes raised edges along opposing lateral sides of the user interface 138, the raised edges being configured to facilitate a user's grip on the handle 110. In this illustrated embodiment, the user interface 138 extends between the first handle housing 114a of the handle 110 and the second handle housing 114b of the handle 110. In another embodiment, the user interface 138 may intersect the filter 142.

[0055] Wiring coupling the user interface 138 to the electrical components 126 is routed to the side of the user interface 138 and not directly underneath the user interface 138 to ensure that the fluid flow path P does not restrict or limit fluid flow.

[0056] As noted above, the user interface 138 can include one or more actuators configured to control operation of the hair care appliance 100 based on user input. For example, the user interface 138 can include a blowout feature 144, which is shown as a button in this illustrated embodiment. Actuation of the blowout feature 144 is designed to cause the heater assembly 132 to shut off so that only unheated air is expelled through the outlet 122. In some embodiments, the blowout feature 144 can be remote from the user interface 138, or located within the user interface 138 but remote from other features of the user interface 138.

[0057] The user interface 138 can also include a fan setting feature 146, which is shown as a button in this illustrated embodiment. Actuation of the fan setting feature 146 is designed to control the speed of the fan assembly 128. The fan setting feature 146 is configured to be repeatedly selectable to produce a high, medium, and low fluid flow through the fan assembly 128.

[0058] The user interface 138 also includes a temperature setting feature 148, which is shown as a button in this illustrated embodiment. Actuation of the temperature setting feature 148 is designed to control the 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 a very high, high, medium, or low temperature. In some embodiments, the high temperature setting can cause the heater assembly 132 to heat the fluid flow to 100°C.

[0059] As FIG. 5 As further shown in the middle, the user interface 138 includes a power feature 150, which is shown as a button in this illustrated embodiment. Actuation of the power feature 150 is designed to control the supply 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. As noted above, the user interface 138 also includes one or more tactile features 152. As in this illustrated embodiment, the tactile features 152 can be raised edges or grip features configured to improve the user’s grip and manual dexterity when holding or operating the hair care appliance 100.

[0060] In some embodiments, the actuators of the user interface 138 (e.g., features 144, 146, 148, 150) can be configured to avoid accidental engagement by a user. For example, one or more of the 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 are configured to enable a user to operate the hair care appliance 100 without inadvertently contacting unintended actuators. In some embodiments, any of the actuators of the user interface 138 described herein can be configured with a light emitting or illuminating element capable of illuminating the actuator or surface of the user interface 138, such as an interior or lower surface of the user interface 138. The configuration and styling of the user interface features described herein can be provided in various non-limiting configurations on the handle 110 of the hair care appliance 100 described herein.

[0061] The hair care appliances described herein, such as the hair care appliance 100 of FIG. 1 to FIG. 5 The hair care appliance 100 of the hair care appliance 100 described herein includes various features configured for improving ease of hair styling, hair heating, and the durability of the hair style applied using the appliance. For example, in one embodiment, the hair care appliance includes an accessory mating assembly configured to couple the appliance to a selected one of various accessories, also referred to as a fitting, which in some embodiments can be powered. The use of a powered accessory can advantageously enhance hair styling by positioning a heating element and / or sensor in the accessory and thus closer to the hair being styled than would be the case if the heating element and / or sensor were in the hair care appliance. The powered accessory can also include a user interface element configured to provide visual, audible, and / or tactile feedback to a user related to the styling process of the hair care appliance and / or operation of the powered accessory releasably coupled to the hair care appliance. The styling experience of a user can be enhanced using a powered accessory that can be easily coupled to the hair care appliance via the accessory mating assembly configured to couple with an accessory mating mechanism of the selected powered accessory. The provision of power and / or communication circuitry between the hair care appliance and the powered accessory via the accessory mating mechanism can extend the operation and functionality of the hair care appliance.

[0062] FIG. 6An example embodiment of a hair care appliance 200 is illustrated 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. In this illustrated embodiment, the curling attachment 204 has an overall elongated cylindrical configuration having a plurality of heating panels thereon, as discussed further below. The illustrated curling attachment 204 also includes a user interface 206 at a distal end of the attachment 204. In some embodiments, such 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 The curling attachment 204 is shown, but a variety of non-limiting attachments can be contemplated that can be configured to be coupled to the hair care appliance 200 via the attachment mating assembly 202 described herein. Other examples of attachments are discussed herein.

[0063] The attachment mating assembly 202 is disposed at a distal end of the hair care appliance 200 and surrounds an outlet 210 of the hair care appliance 200. As shown, the attachment mating assembly 202 is in the form of an annular body having mating features thereon.

In the illustrated embodiment, the attachment coupler 212 is likewise in the form of an annular body having mating features 234 thereon that are configured to mate with corresponding mating features on the attachment mating assembly 202. FIG. 7 FIG. 7 The attachment coupler 212 includes an opening 218 through which air flow exiting the outlet 210 of the hair care appliance 200 enters the attachment in the event that an attachment including the attachment coupler 212 is coupled to the hair care appliance 200. The attachment couplers described herein, such as but not limited to the attachment coupler 212, can be referred to as attachment collars.

[0064] While a variety of mating features can be utilized to mate the attachment coupler 212 to the attachment mating assembly 202, in the illustrated embodiment, the attachment coupler 212 includes a plurality of tabs 236, 238 (see FIG. 8B ), which are configured to extend into corresponding slots 214, 242 (see FIG. 7 and FIG. 9 ​). An accessory including the accessory coupler 212 is thus configured to be coupled to the accessory mating assembly 202 by aligning the protrusions 236, 238 with the slots 214, 242 of the accessory mating assembly 202 and applying a linear force along the longitudinal axis of the accessory and appliance 200. The accessory mating assembly 202 also includes a rotatable release mechanism 220, such as a rotatable ring as shown (see FIG. 9 ), the rotatable release mechanism 220 is configured to engage the protrusions 236, 238 within the slots 214, 242 to prevent removal thereof. The ring 220 is spring-biased into the engaged position. Thus, during insertion of the protrusions 236, 238 into the slots 214, 242, the protrusion 216 is configured to rotate the ring 220 away, e.g., out of the engaged position, thereby allowing the protrusions 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 return the rotatable ring to the initial engaged position, thereby engaging the protrusions 236, 238 within the slots 214, 242 to retain the protrusions 236, 238 therein, thereby retaining the accessory coupler 212 to the accessory mating assembly 202. The release mechanism 220 is configured to secure the accessory coupler 212 to the accessory mating assembly 202 such that the accessory, including the accessory coupler 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 the accessory to be released from the appliance 200. Thus, the release mechanism 220 can be referred to as a locking member. The release mechanism 220 is configured to be rotated by a user to disengage the release mechanism 220 from the accessory coupler 212, thereby allowing the accessory to be removed from the hair care appliance 200.

[0065] like FIG. 7 As further shown, the accessory coupler 212 includes a plurality of electrical connectors 222, such as male pins as shown. The male pins are configured to be received within corresponding female receptacles of electrical connectors 224, which are disposed in the accessory mating assembly 202. A variety of non-limiting connector types may be used, such as keyed connectors, locking connectors, spring pins, crown spring connectors, crimp connectors, or blade connectors. Additionally, the configuration of the electrical connectors 222, 224 may vary. For example, in some embodiments, the accessory coupler 212 may include female connectors and the accessory mating assembly 202 may include male connectors, or vice versa. The position or configuration of the electrical connectors 222, 224 on the accessory mating assembly 202 (and the corresponding position on the accessory coupler 212) may also vary. For example, as FIG. 7As shown, two sets of adjacent 4-pin connectors are shown in respective positions around the circumference of the accessory mating assembly 202 and the accessory coupler 212. In some embodiments, the sets of electrical connectors 222, 224 can be positioned opposite each other or spaced apart from each other around the circumference of the accessory mating assembly 202 and the accessory coupler 212. In some embodiments, a set of connectors can include 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 connectors. The configuration of the electrical connectors 222, 224 can be configured to provide a small diameter body or housing for the appliance 200, ease wiring, and can reduce airflow obstruction through the appliance 200.

[0066] With the accessory coupled to the appliance 200, the electrical connectors 222 of the appliance 200 and the electrical connectors 224 of the accessory are configured to communicatively couple to electrical components of the appliance 200, such as a PCB, a fan assembly, a motor, a user interface, a switch, or other components configured in the appliance 200 via the wiring. The electrical connectors 222 and the electrical connectors 224 connected thereto are also configured to communicatively couple to electrical components of the accessory, such as a heating element, a heating assembly, a sensor, or a user interface configured in the accessory via the wiring. The electrical connectors 222, 224, when connected, are configured to transfer power signals and / or data signals between the appliance 200 and the accessory.

[0067] For example, in one embodiment, a first set of electrical connectors 222, 224 is configured to transfer power between the appliance 200 and an accessory coupled thereto, or vice versa. The first set can include first and second power pins, first and second neutral pins, and a local ground pin or a local ground pin. A second set of electrical connectors 222, 224 is configured to transfer data between the appliance 200 and an accessory 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.

[0068] As described above, the accessory coupler 212 can include a ring structure with an opening 218 therein as in this illustrated embodiment to allow airflow from the outlet 210 of the appliance 200 into an accessory coupled to the appliance 200. The accessory coupler 212 includes a first distal side, as FIG. 8A As shown, the first side includes a housing 226 at which the electrical connectors 222 are configured to receive electrical wires from electrical components of an accessory including the accessory coupler 212. The first side also includes a ferrule 228 extending distally away from the first side. The ferrule 228 is configured to secure the accessory coupler 212 to an accessory. As FIG. 8BAs shown, the second, opposite proximal side of the accessory coupler 212 includes a plurality of prongs 230 that extend proximally from the housing 226 on the first side of the accessory coupler 212 and are configured to be received by a receptacle of the electrical connector 222 that is configured in the accessory mating assembly 202 of the implement 200. The second side also includes a second collar 232 that extends proximally away from the second side. The second collar 232 includes engagement features 234 that are configured to align and secure the accessory coupler 212 within the accessory 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 that are configured to engage with the release mechanism 220 of the accessory mating assembly 202. As shown, a first element 236 of the pair of engagement features 234 can be a protrusion that extends radially away from the second collar 232 along its length. The first element 236 is configured to be received by a slot 242 of a locking ring 244 (see FIG. 7 and FIG. 9 ) of the accessory mating assembly and seated within a slot 214 (see FIG. 9 ) of the housing of the implement 200. A second element 238 of the pair of engagement features 234 includes a protrusion with an angled face that is co-located on the second collar 232 with the first engagement feature 236 proximate the second side. The angled face of the second element 238 is configured to be received by a slot 242 of the locking ring 244 (see FIG. 7 and 9 ) and engage a corresponding protrusion 240 with an angled face on the release mechanism 220.

[0069] As described above, the accessory mating assembly 202 of the implement 200 includes a locking ring 244 that is configured to secure the release mechanism 220 and the electrical connector 222 in place at the distal end of the implement 200. The locking ring 244 includes a protruding tab 246 that extends proximally toward the implement 200, through the release mechanism 220 and into engagement with the slot 214 disposed on the inner surface of the implement body or housing 260. The protruding tab 246 is configured to secure the locking ring 244 to the implement 200 and maintain the release mechanism 220 in an operable position for rotation. The protruding tab 246 also includes a slot 242 that the engagement features 234 on the second collar 232 of the accessory coupler 212 are configured to be received in when the accessory is mated to the implement 200. A set of additional protrusions 216 (see FIG. 8B ) co-located on the second collar 232 with the prongs 230 of the accessory coupler 212 are configured to be received within corresponding slots 248 formed on the surface of the electrical connector 224 to provide additional stability when the accessory is secured to the implement 200.

[0070] The accessory mating assembly 202 also includes a compression spring 250 (see FIG. 9 ) or other force-generating element disposed in a channel 252 formed within the housing 260 of the implement 200. The compression spring 250 is configured to be compressed within the channel 252 when a user rotates the release mechanism 220 to decouple the accessory coupler 212 (and thus the accessory comprising the accessory coupler 212) from the implement 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 to engage an end of the channel 252 at a second, opposite end of the spring 250. The compression spring 250 is configured to extend against the end of the channel 252 and to exert a force against the release mechanism protrusion 240 in response to a user releasing the release mechanism 220, thereby returning or resetting the release mechanism 220 to a position in which it is ready to receive an accessory, which can be the same accessory that was just released or a different accessory.

[0071] When an accessory is secured to the implement 200, a second feature 238 of the pair of engagement features on the second side of the accessory coupler 212 is configured to engage the protrusion 240 on the release mechanism 220. For example, a portion of the second feature 238 having an angled face is oriented to correspond with an angled face on the protrusion 240 of the release mechanism 220. The release mechanism 220 is configured to rotate slightly by movement of the compression spring 250 to enable the corresponding angled face of the second feature 238 of the accessory coupler 212 to engage the protrusion 240 of the release mechanism 220. A first feature 236 of the pair of engagement features on the second side of the accessory coupler 212 is configured to engage a non-angled face of the release mechanism protrusion 240 to prevent rotation of the accessory within the accessory mating assembly 202. In this way, the release mechanism 220 is configured to securely secure the accessory to the implement 200 by linearly connecting the accessory coupler 212 to the accessory mating assembly 202.

[0072] The accessory mating assembly 202 is configured to receive the accessory coupler 212 therein and to bring the electrical connectors 224 of the accessory mating assembly 202 into contact with the corresponding electrical connectors 222 of the accessory coupler 212, as shown in the cross-sectional view of FIG. 10 . As further shown in FIG. 10 , the body 260 of the implement 200 includes a frame 254 therein. The frame 254 includes a cavity 256 extending along a length of the frame 254. A fluid flow path 258 (shown in dashed lines) extends through the cavity 256 of the frame 254.

[0073] FIG. 22A to FIG. 22C Another example embodiment of a hair care implement 1000 is illustrated, having an accessory mating assembly 1002 configured to couple an accessory, such as FIG. 6the attachment 204 of FIGS. 1-3, FIG. 11 the attachment 300 of FIGS. 4-6, FIG. 16 the attachment 400 of FIGS. 7-9, FIG. 17 the attachment 500 of FIGS. 10-12, FIG. 18 the attachment 602 of FIGS. 13-15, FIG. 19 the attachment 702 of FIGS. 16-18, or other attachments, are coupled to the hair care appliance 1000. The hair care appliance 1000 is generally configured and used in a manner similar to the hair care appliance 200 of FIGS. 1-3, for example, including a housing 1060, an air outlet 1008, and an air inlet 1010 that is obscured in FIG. 6 to FIG. 10 the elements that are obscured in FIG. 19 include the air inlet, the user interface, the motor, the handle, the fan assembly, etc., and are therefore not specifically illustrated. FIG. 22A to FIG. 22C

[0074] The attachment fitting assembly 1002 is disposed at a distal end of the housing 1060 of the blow dryer and surrounds the air outlet 1008 of the hair care appliance 1000. The attachment fitting assembly 1002 is in the form of an annular body having fitting features thereon. The attachment (such as the attachment 204 of FIGS. 1-3, FIG. 6 the attachment 300 of FIGS. 4-6, FIG. 11 the attachment 400 of FIGS. 7-9, FIG. 16 the attachment 500 of FIGS. 10-12, FIG. 17 the attachment 602 of FIGS. 13-15, FIG. 18 the attachment 702 of FIGS. 16-18, or other attachments, are coupled to the attachment fitting assembly 1002. FIG. 19

[0075] While various fitting features can be utilized to fit the attachment coupler 1004 to the attachment fitting assembly 1002, in the illustrated embodiment, the attachment fitting assembly 1002 includes a plurality of tabs 1036 that extend distally. The plurality of tabs are configured to each extend into a corresponding one of a plurality of slots 1006 formed in a proximal end of the attachment coupler 1004. The plurality of tabs 1036 extend from a sidewall of a channel 1040 that extends around a perimeter of the attachment fitting assembly 1002, which in this illustrated embodiment, extends around a circumference of the attachment fitting assembly 1002, which is substantially circular in shape. The attachment that includes the attachment coupler 1004 is configured to be coupled to the attachment fitting assembly 1002 by aligning the tabs 1036 with the slots 1006 of the attachment coupler 1002 and applying a linear force along the longitudinal axis of the attachment and the hair care appliance 1000. In some embodiments, in addition to the linear force, a rotational force can be applied to one or both of the attachment and the hair care appliance 1000 to fully engage the tabs 1036 within their respective slots 1006.

[0076] ​​The tabs 1036 are operably coupled to a lock 1010 of the hair care appliance 1000. The lock 1010 is configured to be actuated by a user to facilitate secure coupling and release of the accessory coupler 1004 to the hair care appliance 1000.

[0077] In the illustrated embodiment, the lock 1010 is in the form of a latch that is operably coupled to the plurality of tabs 1036. Actuation of the lock 1010 is configured to move the tabs 1036 relative to the housing 1060. The tabs 1036 are configured to move from an extended configuration to a retracted configuration by moving the latch 1010. In the FIG. 22A and 22C extended configuration, the tabs 1036 extend distally to allow the tabs 1036 to engage the slot 1006 of the accessory coupler 1004. In the retracted configuration, the tabs 1036 are retracted proximally from their position in the extended configuration to allow the tabs 1036 to disengage from the slot 1006 of the accessory coupler 1004. Thus, with the accessory coupled to the hair care appliance 1000, such as with the accessory mating assembly 1002 coupled to the accessory coupler 1004, actuation of the latch 1010 is designed to disengage the tabs 1036 from the slot 1006 and thereby allow the accessory to be removed from the hair care appliance 1000.

[0078] As FIG. 22B illustrated, the accessory mating assembly 1002 includes a plurality of electrical connectors 1024. The electrical connectors 1024 are configured to couple with at least one electrical connector of the accessory coupler 1004. In the illustrated embodiment, the plurality of electrical connectors 1024 of the accessory mating assembly include a plurality of male pins, and the at least one electrical connector of the accessory coupler includes at least one female receptacle. The plurality of electrical connectors 1024 of the accessory mating assembly are configured to be received in a respective one or more of one or more receptacles positioned on a bottom surface of the accessory coupler 1004.

[0079] The electrical connectors 1024 of the accessory mating assembly 1002 and the accessory coupler 1004 are generally configured and used in a manner similar to the electrical connectors 222, 224 discussed above. FIG. 7 FIG. 7 Similar to the above description of the electrical connectors 222, 224, the electrical connectors 1024 of the hair care appliance 1000 and the corresponding electrical connectors (e.g., metal pads or other electrical connectors) of the accessory are configured to communicatively couple to electrical components of the hair care appliance 1000, such as a PCB, a fan assembly, a motor, a user interface, a switch, or other components configured in the hair care appliance 1000 via wiring.

[0080] ​In the illustrated implementation, each of the electrical connectors 1024 of the accessory mating assembly is operably coupled to a spring (not shown). The spring is configured to allow the electrical connectors 1024 to move, e.g., retract, in response to being received in the receptacle(s) of the accessory coupler 1004. The spring biases the electrical connectors 1024 to the extended configuration. Thus, when the accessory is removed from the hair care appliance 1000, the spring is configured to move the electrical connectors 1024 from the retracted configuration to the extended configuration to prepare the accessory mating assembly 1002 for the next coupling with an accessory (the same accessory or a different accessory).

[0081] An electrical path is formed when the electrical connectors 1024 of the accessory mating assembly 1002 couple with the electrical connectors of the accessory coupler 1004. In the illustrated implementation, the coupling includes the electrical connectors 1024 of the accessory mating assembly 1002 being seated in the receptacle(s) of the accessory coupler 1004. The receptacle can have a variety of configurations, such as including one or more of a metal pad, a recess, a groove, a through-hole, and an opening. For example, the receptacle can be configured to receive more than one electrical connector 1024, or the receptacle can be configured to receive only one electrical connector 1024.

[0082] While pins and receptacles are used in the illustrated implementation, a variety of non-limiting connector types can be used as the electrical connectors 1024 of the accessory mating assembly 1002 and the accessory coupler 1004, such as keyed connectors, spade connectors, locking connectors, slip rings (e.g., flat slip rings, through-hole slip rings, or other slip rings), spring pins, crown spring connectors, crimp connectors, and / or blade connectors. For example, the accessory mating assembly 1002 can include a female portion of a spade connector, and the accessory coupler 1004 can include a male portion of the spade connector, or vice versa. In another example, the accessory mating assembly 1002 can include a male portion of a plug connector, and the accessory coupler 1004 can include a female portion of the plug connector, or vice versa. In yet another example, a custom type of connector can be used that is based on one or more electrical characteristics associated with the performance of the hair accessory described herein, such as current, voltage, power, or any other characteristic.

[0083] Any of the connectors described herein can include a lock, such as a movable arm, a fastener, a magnet, or a combination thereof, to prevent inadvertent disengagement of the connector.

[0084] In an exemplary embodiment, as described above, the accessory coupler 1004 is configured to be coupled to the accessory mating assembly 1002 by applying a linear force along the longitudinal axis of the accessory and the hair care appliance 1000. Thus, the electrical connector 1024 of the accessory mating assembly 1002 and the accessory coupler 1004 is configured as a plurality of male pins and female sockets to be coupled by applying a linear force. No rotational force is applied or required to achieve the coupling of the accessory mating assembly 1002 and the accessory coupler 1004, which can help ensure that the coupling occurs because the coupling does not rely on the user rotating the accessory and / or the hair care appliance 1000 by at least a certain amount. Other connector types are also configured to achieve coupling by applying a linear force without applying a rotational force, such as spade connectors, slip rings, and custom plugs and sockets. However, in some embodiments, coupling can be achieved by linear translation and / or rotation of one or more components (e.g., the male portion of the connector) so as to be coupled to one or more separate components (e.g., the female portion of the connector).

[0085] The configuration of the electrical connector 1024 can vary. For example, FIG. 22B As shown, a total of seven electrical connectors 1024 are shown as being positioned around the periphery of the accessory mating assembly 1002, which in the illustrated embodiment is around the circumference of the substantially circular-shaped accessory mating assembly 1002. In particular, the electrical connectors 1024 are positioned around the periphery of the air outlet 1008 and are positioned within the channel 1040. In some embodiments, the electrical connectors 1024 are positioned relative to each other or separately from each other around the periphery of the accessory mating assembly 1002 and similarly around the periphery of the accessory coupler 1004. In some embodiments, the number of electrical connectors can be between two and twenty connectors. The configuration of the electrical connectors 1024 of the hair care appliance 1000 can be configured to provide the hair care appliance 1000 with a small diameter body or housing, ease of wiring, and reduced airflow obstruction in the appliance 1000.

[0086] The accessory mating assembly 1002 includes one or more movable actuators. As in the illustrated embodiment, the one or more movable actuators of the accessory mating assembly 1002 can include a latch 1010 and a button 1014. The latch 1010 is received and movable within a latch opening 1012 formed through a side wall of the housing 1060 to allow a user to access the latch 1010. The latch 1010 is configured to translate back and forth within the latch opening 1012. FIG. 22A and FIG. 22CThe latch 1010 is shown in the first position positioned at a first end of the latch opening 1012. The latch 1010 is configured to move from the first position to a second position at a second end of the latch opening 1012, opposite the first end of the latch opening 1012. The latch 1010 is also configured to move from the second position to the first position. The latch 1010 is operably coupled to a spring 1016. The spring 1016 is configured to bias the latch 1010 toward the first position. Thus, when the latch 1010 is moved from the first position to the second position, the spring 1016 automatically urges the latch 1010 back to the first position, and thus, readies the hair care appliance 1000 for attachment to another accessory (the same accessory or a different accessory).

[0087] The button 1014 is configured to translate within the channel 1040. The button 1014 is in an extended configuration (e.g., the button 1014 protrudes into the channel 1040) shown in FIG. 10A, and is configured to move from the extended configuration to a retracted configuration (e.g., an outer surface of the button 1014 is flush with a bottom of the channel 1040). FIG. 22C

[0088] The latch 1010 and the button 1014 are mechanically connected in such a way that movement of the button 1014 from the extended configuration to the retracted configuration (e.g., by depressing the button 1014) is designed to move the latch 1010 from the first position of the latch to the second position of the latch. The spring 1016 is configured to return the latch 1010 to the first position, as described above, while the button 1014 remains in the retracted configuration. The button 1014 is configured to contact the accessory coupler 1004 if the accessory coupler 1004 is coupled to the accessory mating assembly 1002. Thus, coupling the accessory coupler 1004 to the accessory mating assembly 1002 includes depressing the button 1014, e.g., by linearly connecting the accessory coupler 1004 to the accessory mating assembly 1002, and thereby also moving the latch 1010 from the first position to the second position. In addition to being configured to move in response to movement of the button 1014, the latch 1010 is configured to be moved by a user. For example, the latch 1010 is configured to be moved from the first position to the second position by a user. Movement of the latch 1010 in response to user input does not affect the position of the button 1014. That is, the button 1014 will not move between the retracted configuration and the extended configuration in response to movement of the latch 1010.

[0089] ​The electrical connection between the hair care appliance 1000 and the accessory is configured to be controlled using one or more actuators. In the illustrated embodiment, each of the latch 1010 and the button 1014 is electrically coupled to a micro switch 1018. The micro switch 1018 is further electrically coupled to a plurality of electrical connectors 1024. The position of the latch 1010 determines the position of the micro switch 1018, which determines whether the micro switch 1018 allows or prevents an electrical signal to the electrical connectors 1024. The position of the micro switch 1018 thus corresponds to the position of the latch 1010. The micro switch 1018 is configured to transmit an electrical signal to the electrical connectors 1024 if the latch 1010 is in the first position, and is unable to transmit an electrical signal to the electrical connectors 1024 if the latch 1010 is in the second position. Similarly, the position of the button 1014 determines whether the micro switch 1018 can provide an electrical signal to the electrical connectors 1024. The micro switch 1018 is configured to transmit an electrical signal to the electrical connectors 1024 if the button 1014 is in the retracted position, and is unable to transmit an electrical signal to the electrical connectors 1024 if the button 1014 is in the extended position.

[0090] Preventing the electrical signal from being transmitted by the micro switch 1018 to the electrical connectors 1036 can avoid the risk of being associated with electrical arcs and / or sparks during use of the hair accessory described herein. For example, the electrical signal provided by the micro switch 1018 to the electrical connectors 1036 can be stopped prior to coupling the accessory coupler 1004 to the accessory mating assembly 1002 by moving the button 1014. In particular, the accessory coupler 1004 is configured to depress the button 1014 by linearly connecting the accessory coupler 1004 to the accessory mating assembly 1002, e.g., moving the button 1014 from the extended configuration to the retracted configuration. The depression of the button 1014 is designed to move the latch 1010 from the first position to the second position, and thus the micro switch 1018 to prevent the electrical signal from being provided to the electrical connectors 1036. In a similar manner, the electrical signal provided by the micro switch 1018 to the electrical connectors 1036 can be stopped prior to the user moving the latch 1010 to thereby decouple the accessory coupler 1004 from the accessory mating assembly 1002. In particular, the user moving the latch 1010 from the first position to the second position is designed to cause the micro switch 1018 to prevent the electrical signal from being provided to the electrical connectors 1036. Thus, the accessory coupler 1004 can be coupled and decoupled from the accessory mating assembly 1002 without any electrical arcs or sparks therebetween.

[0091] configured for use with a hair care appliance (e.g., FIG. 1 to FIG. 5 the hair care appliance 100 of FIG. 6 to FIG. 10 the hair care appliance 200 of FIG. 22A to FIG. 22C the hair care appliance 1000 of or other hair care appliances) and an accessory mating assembly (e.g.,FIG. 7 the accessory mating assembly 202 of the hair care appliance 100 of FIG. 22A to FIG. 22C One exemplary embodiment of an accessory for use with the accessory mating assembly 1002 of the hair care appliance 1000 of FIG. 6 One exemplary embodiment of a curling accessory is shown in FIG. 30, and is configured and used in a manner similar to the curling accessory 200 of FIG. 11 FIG. 28. The curling accessory 300 includes an elongated body 302 extending between an attachment end 304 and a distal end 306. The attachment end 304 is configured to mate with a hair care appliance (e.g., the hair care appliance 100 of FIG. 7 to FIG. 10 the accessory coupling 212 of the hair care appliance 200 of FIG. 1 to FIG. 5 the hair care appliance 100 of FIG. 6 to FIG. 10 the hair care appliance 200 of FIG. 22A to FIG. 22C the hair care appliance 1000 of or other hair care appliance) via an accessory coupling 314 (e.g., the accessory coupling 212 of the hair care appliance 200 of FIG. 12 FIG. 28). The distal end 306 includes an end cap 308 having a cylindrical or other shaped protrusion extending away from an end plate 310 of the end cap 308, as shown in FIG. 28. The end plate 310 has a diameter that is greater than a diameter of the body 302 to protect a user's fingers from the heated surface of the body 302 when the curling accessory 300 is grasped at the distal end 306.

[0092] As also shown in FIG. 12 to FIG. 15 FIG. 28, the accessory 300 includes wiring 312 configured to mate an electrical connector of the accessory coupling 314 with electrical components of the curling accessory 300, such as LEDs (and / or other types of lights), sensors, haptic feedback mechanisms, etc. The LEDs (and / or other types of lights), sensors, haptic feedback mechanisms, etc. in the accessory 300 are configured to provide user feedback regarding operation of the accessory 300. In some embodiments, the user feedback can be visual, audible, and / or haptic feedback. For example, the haptic feedback mechanisms can be configured to generate vibrations that can be sensed by a user having accessibility requirements. In some embodiments, a motor of the hair care appliance that is coupled by the accessory 300 can be configured to generate haptic feedback. In some embodiments, the wiring 312 can be entirely enclosed within the curling accessory 300.

[0093] The curling attachment 300 includes a plurality of longitudinally configured plates 316 configured to be heated and to form curls in hair when the heated plates 316 are brought into contact with the hair. An airflow is configured to be received from a hair care appliance to which the curling attachment 300 is attached via an inlet 318 of the curling attachment 300 and to pass through a body 302 of the curling attachment 300. The airflow is configured to exit the curling attachment 300 via outlets 320 that are arranged longitudinally along the body 302 between adjacent plates 316. The airflow tangentially exiting the surface of the curling attachment 300 is configured to induce a Coanda effect. The Coanda effect allows the hair to wrap around the outer surface of the curling attachment 300 without the user having to directly manipulate the hair onto the heated curling attachment 300.

[0094] The curling attachment 300 also includes a heater 322, as shown in FIG. 13 and FIG. 14 The heater 322 is in the form of a cylindrical or rod-shaped heater in this illustrated embodiment, such as a cartridge heater, configured within an inner cavity of a heater frame 324. The heater 322 extends along the cavity for the entire length of the body 302, or partially within the cavity at one or more portions of the body 302. The heater frame 324 includes a thermally conductive material, such as a metal. In some embodiments, the plates 316 can also include a coating on the surface of each plate 316 to assist with heat retention and distribution. An end cap 308 is coupled to the heater frame 324. The combination of the airflow and the heater 322 configured within the curling attachment 200 allows the user to obtain the benefits of a thermally conductive curl that automatically wraps the hair around the heated appliance.

[0095] As shown in FIG. 14 The heater frame 324 includes a plurality of arms 326 extending radially from a central longitudinal axis of the heater frame 324. The plates 316 can be integrally formed with each arm 326 as in this illustrated embodiment and can have a curved profile that forms a circumference of the curling attachment 300. The number of arms 326 and plates 316 can vary and can not be limited to the number of arms 326 and plates 316 shown in FIG. 14 The heater frame 324 can be formed via extrusion for efficient manufacturing.

[0096] The heater frame 324 also includes a plurality of flow tunnel 328 formed between adjacent arms 326 of the heater frame 324 and circumferentially bounded by the plates 316. The flow tunnel 328 extends longitudinally along the length of the body 302 and includes a flow cavity 330 therein. A conduit 332 is configured within the flow cavity 330, as shown in FIG. 15The conduit 332 comprises a heat resistant material. The conduit 332 is configured to direct airflow from the inlet 318 to the outlet 320 via vanes 334 formed on an inner surface of the conduit 332. The conduit 332 has a longitudinal opening at which the outlet 320 of the curling attachment 300 is formed adjacent to a longitudinal edge of the corresponding plate 316 of the heater frame 324. To facilitate manufacturing, the conduit 332 can be inserted into the flow path tunnel 328 of the heater frame 324.

[0097] The curling attachment 300 also includes a moisture sensor 336 configured to detect an amount of moisture in the hair of a user using the attachment 300. In FIG. 15 one moisture sensor 336 is shown, but in some embodiments, the curling attachment 300 can include more than one moisture sensor 336. As shown in FIG. 15 the illustrated embodiment, the moisture sensor 336 can be positioned between the conduit 332 and the plate 316. In some embodiments, the moisture sensor 336 can extend the entire length of the body 302 or partially within the body 302. In some embodiments, the moisture sensor 336 can comprise a capacitive moisture sensor. The moisture sensor 336 is configured to be communicatively coupled to other electrical components of a hair care appliance to which the curling attachment 300 is attached via the attachment coupler 314. Sensing data obtained by the moisture sensor 336 is configured to be provided to a microprocessor or controller of the hair care appliance to which the curling attachment 300 is attached and 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 a predetermined heating and / or drying (e.g., airflow) operation based on the amount of moisture determined from the sensor data obtained via the moisture sensor 336.

[0098] Another exemplary embodiment of an attachment configured to cooperate with a hair care appliance (e.g., FIG. 1 to FIG. 5 the hair care appliance 100 of FIG. 1, FIG. 6 to FIG. 10 the hair care appliance 200 of FIG. 2, FIG. 22A to FIG. 22C the hair care appliance 1000 of FIG. 10, or other hair care appliance) and an attachment mating assembly (e.g., FIG. 7 the attachment mating assembly 202 of FIG. 2, FIG. 22A to FIG. 22C the attachment mating assembly 1002 of FIG. 10, or other attachment mating assembly) includes a concentrator attachment. FIG. 16 One exemplary embodiment of a concentrator attachment 400 is shown and includes a heating element 402. The heating element 402 is configured to cooperate with an attachment coupler 404 of a concentrator attachment described herein (e.g., FIG. 7 to FIG. 10 the attachment coupler 212 of FIG. 2, FIG. 22AThe electrical connector of the accessory coupling 1004 or other accessory coupling of the concentrator attachment 400 is communicatively coupled to an electrical component of the hair care appliance to which the concentrator attachment 400 is attached. In this way, the heating element 402 is configured to provide additional heat to the airflow output at the outlet 406 of the concentrator attachment 400 and in close proximity to the hair for improved styling results.

[0099] In some implementations, an accessory can include an ion generator therein. The ion generator can be positioned in the accessory to maximize the amount of ions received by the hair. The ion generator is configured to be communicatively coupled to an electrical component of the hair care appliance to which the accessory is attached via the electrical connector of the accessory coupling of the accessory described herein. As FIG. 16 shown, the illustrated implementation of the concentrator attachment 400 includes an ion generator 408 positioned within the outlet 406.

[0100] In some implementations, an accessory can include one or more torque sensors therein. The torque sensors can be configured relative to bristles, such as the bristles 504 of the brush attachment 500, as FIG. 17 shown. The brush attachment 500 is another exemplary implementation of an accessory for use with a hair care appliance (e.g., the hair care appliance 100 of FIG. 1 to FIG. 5 the hair care appliance 100, FIG. 6 to FIG. 10 the hair care appliance 200, FIG. 22A to FIG. 22C the hair care appliance 1000 or other hair care appliance) and an accessory mating assembly (e.g., the accessory mating assembly 202 of FIG. 7 the accessory mating assembly 202, FIG. 22A to FIG. 22C the accessory mating assembly 1002 or other accessory mating assembly) described herein. The torque sensors (e.g., the torque sensors 502 of the brush attachment 500 or other torque sensors of another accessory) are configured to be coupled to an electrical component of the hair care appliance to which the accessory including the torque sensors is attached via the electrical connector of the accessory coupling of the accessory described herein. The torque sensors are configured to generate sensor data associated with an amount of torque applied to at least one bristle or brush set as a user uses the accessory (e.g., to comb the hair using the brush attachment 500). The amount of torque is associated with a condition of the hair and, thus, an operating parameter of the hair care appliance can be determined. For example, the torque sensor data can be used to determine whether the user has dry or tangled hair based on an elevated torque value that indicates that more force is required to comb the dry or tangled hair. A lower torque value is associated with wet, oily, or fine hair, indicating that less force is required to comb the hair. The hair care appliance with the attached accessory as described herein can be configured to adjust one or more of a heating temperature or an airflow setting based on the sensed torque data.

[0101] Styling hair may require specific skills and hair handling to achieve the desired style. Some users may lack the specific skills necessary to utilize a hair care appliance to achieve their desired style. Therefore, it may be desirable for the hair care appliance and / or accessories to provide user feedback and / or automatic styling assistance. For example, a Coanda curl is a specific method for curling unruly hair. The user may need to use a curling attachment, such as FIG. 6 Curl attachment 204, FIG. 11 The curling attachment 300 or other curling attachment automatically wraps hair around a curler by generating an airflow that pulls the hair into position around the heated plate of the curling attachment. After wrapping the hair around the body of the curling attachment, the user then heats the hair for a set period of time and then cools the hair for a set period of time to achieve the curl. The user may not know where to contact the hair on the attachment, have difficulty styling within the desired time period, lose track of time, or have difficulty styling while viewing their reflection in a mirror.

[0102] Hair care appliance as herein described and powered annex can remedy these problems by obtaining the data about the user's hair and providing feedback to the user when the user is styling their hair. Feedback can ensure that the best practices associated with a specific styling technique are communicated to the user. Feedback can be provided via the visual, auditory and / or tactile feedback mechanisms provided in powered annex as herein described. The electrical connection realized between annex and the hair care appliance herein can provide a series of robust feedback and operating modes, to improve the user's experience and produce improved lasting styling effects.

[0103] For example, in FIG. 18 In one embodiment shown, a user can operate a hair care appliance 600 as described herein in a manual mode of operation (e.g., FIG. 1 to FIG. 5 Hair care products 100, FIG. 6 to FIG. 10 Hair care products 200, FIG. 22A to FIG. 22C The hair care appliance 1000 or other hair care appliance) and the powered curling attachment 602 (e.g., FIG. 6 Curl attachment 204, FIG. 11 300 or other curling attachments). FIG. 16As shown, a user can activate the manual actuator 604 (shown as a switch in this illustrated embodiment) of the hair care appliance 600 with the appliance 600 attached to the powered curling attachment 602 to initiate a timed procedure for curling hair. The switch 604 is configured to communicatively couple to the curling attachment 602 via the electrical connector of the attachment coupler of the curling attachment, which can include a user interface such as the LEDs 606 and audible output 608, as shown in this illustrated embodiment. The switch 604 is also configured to communicatively couple to the electrical components of the hair care appliance 600, which can include a user interface (e.g., LEDs 610 and audible output 612), a heater 614, a motor 616, a microprocessor and / or controller 618 coupled to a memory storing non-transitory computer executable instructions (e.g., “software control”) associated with one or more operating parameters and / or operating modes of the hair care appliance 600, as shown in this illustrated embodiment.

[0104] Activating the manual switch 604 is designed to turn on the hair care appliance 600, and the user can wrap their hair around the curling attachment 602 attached to the hair care appliance 600. The user can then manually actuate the timed actuator, e.g., press the timed initiator of the user interface of the hair appliance, to initiate the series of operating modes required to perform the curl. The software control is configured to generate control signals provided to the various electrical components in the attachment 602 and the hair care appliance 600, such as the user interfaces 606, 608, 610, 612, the heater 614, or the motor 616. The control signals are configured to initiate the predetermined timed cycle required to curl the hair. The control signals are also configured to cause one or more of the user interfaces 606, 608, 610, 612 to provide feedback to the user to indicate the point at which the user should manually switch to the next stage of the curl.

[0105] In some embodiments, the curling attachment is configured to provide sensor data from a moisture sensor of the curling attachment to control the operation of the attachment and the hair care appliance to which the attachment is attached via the software control of the hair care appliance. For example, as shown in FIG. 1, the hair care appliance 100 includes a moisture sensor 102 of the curling attachment 104. The software control of the hair care appliance 100 is configured to receive sensor data from the moisture sensor 102 of the curling attachment 104 to control the operation of the attachment 104 and the hair care appliance 100 to which the attachment 104 is attached. FIG. 17 As shown, a user can turn on the hair care appliance 700 (e.g., the hair care appliance 100 of FIG. 1, the hair care appliance 200 of FIG. 2, the hair care appliance 300 of FIG. 3, or the hair care appliance 400 of FIG. 4) with the appliance 700 attached to the powered curling attachment 702 to initiate a timed procedure for curling hair. FIG. 18 the hair care appliance 100 of FIG. 1, FIG. 19 the hair care appliance 200 of FIG. 2, FIG. 20hair care appliance 700) and wraps their hair around the curling attachment 702 attached to the hair care appliance 700. Moisture data determined from the moisture sensor 704 of the curling attachment 702 is structured to be used by the software control 706 of the appliance 700 to determine the requirements for a wet hair style. Based on the detection of the wet hair wrapped around the curling attachment 702, the software control 706 is structured to initiate a timing program that cycles through a predetermined timing cycle. The software control 706 is structured to generate control signals provided to various electrical components in the attachment 702 and the hair care appliance 700, such as a user interface (e.g., the LED 708 of the attachment 702, the audible output 710 of the attachment 702, the LED 712 of the appliance 700, the audible output 714 of the appliance 700, etc.), a sensor (e.g., the moisture sensor 704, etc.), a heater 716, or a motor 718. The control signals are structured to initiate the predetermined timing cycle necessary to curl the hair based on the moisture data obtained via the moisture sensor 704. The control signals are further structured to cause one or more of the user interfaces of the hair care appliance and / or the attachment to provide feedback to the user to indicate the point at which the user should manually switch to the next stage of curling.

[0106] In some embodiments, a hair care appliance (e.g., FIG. 1 to FIG. 5 a hair care appliance 100 of the FIG. 6 to FIG. 10 a hair care appliance 200 of the FIG. 22A to FIG. 22C a hair care appliance 1000 of the or other hair care appliance) and a powered attachment that can be attached to the appliance (e.g., FIG. 20 an attachment 204 of the FIG. 1 to FIG. 5 an attachment 300 of the FIG. 6 to FIG. 10 an attachment 400 of the FIG. 22A to FIG. 22C an attachment 500 of the FIG. 6 an attachment 602 of the FIG. 11 an attachment 702 of the or other attachment) are structured to provide full automatic monitoring and control of the mode of operation of the hair care appliance and / or the attachment. For example, as shown in one embodiment of the FIG. 16 a hair care appliance 800 (e.g., FIG. 17 a hair care appliance 100 of the FIG. 18 a hair care appliance 200 of the FIG. 19A user (e.g., a hair care appliance 1000 or other hair care appliance) wraps their hair around a curling attachment 802 releasably attached to the appliance 800. Moisture data determined from a moisture sensor 804 of the curling attachment 802 is configured to be used (e.g., by a software control 806 of the appliance 800) to determine a desire for damp hair styling. Based on the detection of damp hair wrapped around the curling attachment 802, the software control 806 is configured to initiate a gradual heating program. When the moisture data indicates a predetermined level of moisture, the software control 806 is configured to generate a control signal to cause the heater 808 and motor 810 of the hair care appliance 800 to generate a short burst of relatively warm air for a predetermined period of time. As damp hair continues to be sensed, the software control 806 is configured to cause the heater 808 and motor 810 to generate cool air for subsequent predetermined periods of time. In response to sensing an appropriate moisture level and completion of a previously predetermined cycle of treatment, the software control 806 is configured to cause the hair care appliance 800 to shut down. FIG. 21 Also shown are LED 812 of accessory 802, audible output 814 of accessory 802, LED 816 of appliance 800, and audible output 818 of appliance 800, which are configured to provide information to a user, as discussed herein.

In some embodiments, the second feedback indication can comprise a second color (e.g., color of a light, etc.) different from the first feedback indication, a second sound, etc.

[0109] In response to a manual activation or sensed moisture data obtained at point 4 by a moisture sensor of the attachment from hair wrapped around the attachment, stage 5 begins for drying the hair. During the“hair drying” stage 5, the heater of the attachment heats the heated plate of the attachment to about 140°C for a period of about 5 seconds to dry the wet hair. Also during this stage, the motor is activated to generate a heated airflow via the heating element of the hair care appliance. The generated heated airflow is provided through the outlet 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 comprise a third color (e.g., color of a light, etc.) different from the first feedback indication and the second feedback indication, a third sound, etc.

[0110] After stage 5, the hair care appliance enters stage 6, which is associated with providing a“Hot Shot” volume of heated air for about 5 to 10 seconds.
