Description

BACKGROUND In a conventional air styling device, air is directed towards hair by an attachment or head of a haircare appliance. The attachment or head often comprises bristles onto which hair is wrapped or held for styling, and air is blown out of the attachment or head towards the hair. SUMMARY According to a first aspect, there is provided an attachment for a haircare appliance. The attachment comprises: a casing having an air inlet; first and second movable members movably connected to the casing, the first and second movable members each comprising first and second air outlets in fluid communication with the air inlet; and an auxiliary air outlet defined between the first movable member and the second movable member, the third air outlet in fluid communication with the air inlet. The attachment is operable between a first configuration and a second configuration. In the first configuration, the first and second movable members are in a first position and airflow is directed in a first direction from the respective first and second air outlets and from the auxiliary air outlet to an exterior of the casing. In the second configuration, the first and second movable members are in a second position, different to the first position, and airflow is directed in a second direction from the respective first and second air outlets and from the auxiliary air outlet to an exterior of the casing, the second direction being different to the first direction. In some known haircare appliance attachments, such as air styling brushes, airflow is forced between a gap between two separate moving bodies. There is a limit to how small this gap, which is essentially an outlet of the attachment, can be whilst ensuring that reliable performance across a range of tolerances and a desired airflow directionality is maintained. The moving bodies in such attachments must rotate past one another to change airflow direction around the attachment. If the gap between the moving bodies becomes too small, directionality is lost as the flow tends towards being directed normal to the surface of the attachment. Some attachments may also seek to regulate the size of or close a gap between the moving bodies in order to control the direction of airflow exiting the attachment. However, slight variations in manufacturing tolerances mean that it can be difficult to reliably control the size of such small gaps between the moving bodies. This can mean that the performance of the attachment is negatively affected. In the claimed attachment, the first and second air outlets are outlets in the movable members, rather than gaps between adjacent parts that are movable relative to one another. That is, a size of the first and second air outlets is unaffected by movement of the movable members relative to one another or relative to the casing. By forming the first and second air outlets in the respective first and second movable members, the air outlets can be made smaller because the size of the first and second air outlets is not dependent on the relative positions of adjacent movable members. In addition, the auxiliary air outlet between the movable members enable airflow to pass between the first and second movable members, meaning that the size of the gap between the movable members does not need to be tightly controlled. However, as the attachment is configured to direct airflow in different directions from the first and second air outlets and the auxiliary outlet in each of the two different configurations of the attachment, the directionality of airflow exiting the attachment can be reliably controlled, without requiring high precision manufacturing, reducing potential manufacturing costs. With the movable members in the first position, air may flow around the attachment in a first direction, and with the movable members in the second position, air may flow around the attachment in a second direction, opposite the first direction. For example, in the first position, air may flow in a clockwise direction about a longitudinal axis of the attachment, and in the second position, air may flow in an anti-clockwise direction about the longitudinal axis of the attachment. For example, the first direction and second directions may be orthogonal to the longitudinal axis of the attachment and across an external surface of the movable members. The attachment may further comprise a flow diverter disposed along an airflow path from the air inlet to an exterior of the casing. In the first configuration, the flow diverter may be configured to direct airflow from the auxiliary air outlet in the first direction. In the second configuration, the flow diverter may be configured to direct airflow from the auxiliary air outlet in the second direction. This may enable the attachment to easily control the direction of airflow through the auxiliary outlet between the first and second configurations. In the first configuration, the flow diverter may be configured to direct airflow from the second air outlet of the first movable member in the first direction. In the second configuration, the flow diverter may be configured to detect airflow from the first air outlet of the second movable member in the second direction. This may enable the attachment to control the direction of airflow through the first and second outlets between the first and second configurations. The flow diverter may comprise a first concave surface configured to receive airflow from the second air outlet of the first movable member and divert the received airflow towards the first direction. The first concave surface may enable the airflow to be turned and diverted towards the first direction. The flow diverter may comprise a second concave surface configured to receive airflow from the first air outlet of the second movable member and divert the received airflow towards the second direction. The concave surface may enable the airflow to be turned and diverted towards the second direction. The flow diverter may comprise a first flow diverting member and a second flow diverting member. The first flow diverting member may be disposed adjacent to the second flow diverting member. Having multiple flow diverting members may enable the airflow to be turned in different directions so as to direct the airflow to the required direction to the exterior of the casing. The first and second flow diverting members may be configured to move relative to one another to change the direction of airflow from the first and second air outlets and the auxiliary air outlet between the first and second directions, when the attachment is operated between the first and second configurations. By being able to move relative to one another, the flow diverting members may enable the direction of airflow to be changed between the first and second configurations in a simple manner, without requiring any modulation or regulation of an outlet size. The flow diverter may be integrally formed with the first movable member and / or the second movable member. This may help to reduce the size of the interior cavity required, and thereby reduce the size of the attachment. The first movable member may comprise the first flow diverting member and the second movable member may comprise the second flow diverting member. This can mean that the flow diverting members can move according to the movement of the first and second movable members, which may mean that a separate movement mechanism for the flow diverting members is not required. The first flow diverting member may comprise the first concave surface. The second flow diverting member may comprise the second concave surface. The concave surfaces may enable the airflow to be turned and diverted towards the first and second directions, depending on whether the attachment is in the first or the second configuration. The casing may have a first side edge and an opposing second side edge. The first and second side edges may extend in a direction along the longitudinal axis of the attachment. The movable members may be positioned between the first and second side edges. With the movable members in the first position, air may be emitted from the first and second outlets and the auxiliary outlet towards the first side edge and, with the movable members in the second position, air may be emitted from the first and second outlets and the auxiliary outlet towards the second side edge. The first and second movable members may each be rotatable about a respective first and second axis. The first and second axes may be parallel to one another. This may provide a relatively simple arrangement. The first and second directions may be orthogonal to the first and second axes. The first and second axes may be parallel to a longitudinal axis of the attachment. This may provide a space-efficient and ergonomic arrangement. The first and second movable members may be operably connected to move together between the first and second positions. This may help to ensure that air is directed in the same direction from the first and second movable members. The first and second movable members may each comprise a bristle bed and a plurality of bristles extending from the bristle bed, the bristles for engaging with hair. The attachment may thus be for use as a hair brush. In the first configuration, airflow may be directed from the first air outlet of the first movable member so as to attach to an outer surface of the first movable member. In the first configuration, airflow may be directed from the first air outlet of the second movable member, the second air outlet of the first movable member, and the third air outlet, so as to attach to an outer surface of the second movable member. In the first configuration, airflow may be directed from the second air outlet of the second movable member so as to attach to an outer surface of the casing. In this way, airflow exiting the air outlets can attach to the outer surfaces of the attachment, enabling the direction of airflow around the attachment to be controlled. In the second configuration, airflow may be directed from the first air outlet of the first movable member so as to attach to an outer surface of the casing. In the second configuration, airflow may be directed from the first air outlet of the second movable member, the second air outlet of the first movable member, and the third air outlet, so as to attach to an outer surface of the first movable member. In the second configuration, airflow may be directed from the second air outlet of the second movable member so as to attach to an outer surface of the second movable member. In this way, airflow exiting the air outlets can attach to the outer surfaces of the attachment, enabling the direction of airflow around the attachment to be controlled. An exterior surface of the movable members may comprise a convex curved surface, which may be a Coanda surface, that extends about the respective first or second axis. Similarly, an outer surface of the casing may also be a convex curved surface, which may be a Coanda surface. Accordingly, airflow may be directed in the first and second directions around the attachment, due to the Coanda effect, rather than tangentially to the attachment, which would occur if the exterior surface were flat or concave. The first and second air outlets may be defined in a support member, which supports the bristle bed. The support member may have a higher rigidity than the bristle bed and the bristles. The support member may have a stiffness that is greater than a stiffness of the bristle beds and the bristles. Accordingly, a size of the first and second air outlets may be unaffected by bending of the bristles during use of the attachment. The support member may be formed from aluminium or glass-filled Nylon. The movable members may be movable between the first and second positions in response to engagement of the attachment with hair, for example in response to hair tension at the bristles. Accordingly, the direction of airflow may switch depending on the direction in which the attachment is moved relative to the hair. The attachment may comprise a first edge air outlet defined between the first movable member and a first side of the casing. The attachment may comprise a second edge air outlet defined between the second movable member and a second side of the casing, the second side being opposite to the first side. The first and second movable members may be disposed between the first side and the second side of the casing. In the first configuration, airflow may be directed in the first direction from the first and second edge air outlets to an exterior of the casing. In the second configuration, airflow may be directed in the second direction from the first and second edge air outlets to an exterior of the casing. The first and second edge air outlets may provide additional airflow to an exterior of the casing, for example, to a user’s hair, thereby reducing hair styling time. The direction of airflow from the first and second edge air outlets can be controlled, such that the air flows in substantially the same direction as from the first and second outlets and the auxiliary outlet, in both the first and second configurations. Accordingly, air may be emitted in the same direction from all outlets of the attachment in each configuration. The attachment may further comprise a third flow diverting member and a fourth flow diverting member disposed along an airflow path from the air inlet to an exterior of the casing. The third and fourth flow diverting members may help to divert airflow from the first and second edge air outlets. The third and fourth flow diverting members may be configured to move relative to the casing, such that: in the first configuration, the third flow diverting member may be configured to direct airflow in the first direction from the first edge outlet and the fourth flow diverting member may be configured to direct airflow in the first direction from the second edge outlet; and in the second configuration, the third flow diverting member may be configured to direct airflow in the second direction from the first edge outlet and the fourth flow diverting member may be configured to direct airflow in the second direction from the second edge outlet. The movement of the third and fourth flow diverting members relative to the casing may help to direct airflow from the first and second edge outlets in the first and second directions to an exterior of the casing. The third and fourth flow diverting members may be formed integrally with the first and / or second movable members. This may help to reduce the size of the interior cavity required, and thereby reduce the size of the attachment. The first movable member may comprise the third flow diverting member and the second movable member may comprise the fourth flow diverting member. This can mean that the flow diverting members can move according to the movement of the first and second movable members, which may mean that a separate movement mechanism for the flow diverting members is not required. The third flow diverting member may comprise a third concave surface. The fourth flow diverting member may comprise a fourth concave surface. The concave surfaces may enable the airflow to be turned and diverted towards the first and second directions. The second edge air outlet may be configured, in use with the movable members in the first position, to redirect, towards the first side edge of the casing, air emitted from the second air outlet of the movable member closest to the second side edge of the casing. The first edge air outlet may be configured, in use with the movable members in the second position, to redirect, towards the second side edge of the casing, air emitted from the first air outlet of the movable member closest to the first side edge of the casing. This may increase an amount of airflow that passes across the exterior surface of the movable members, which may improve the haircare performance of the attachment. The first and second air outlets may have a length that is substantially equal to a length of the bristle bed of the respective movable member. Accordingly, a full width of han-contacted by the bristles may be subject to airflow emitted from the first and / or second air outlets. The length of the first and second air outlets may extend parallel to the longitudinal axis of the attachment and / or to the first and second axis. The first and second air outlets may comprise slots disposed on opposing edges of the respective movable member. Accordingly, air may be emitted in different directions from the respective movable member, depending on the position of the movable members. The first and second air outlets of the movable members may have the same length. This may help to ensure that the same width of hair interacts with air emitted from either the first or second air outlets. The first and second air outlets of the first movable member may have the same length as the respective first and second air outlets of the second movable member. This may help to provide more uniform airflow along the length of the movable members. The first air outlet of the first movable member may have a different cross-sectional area to the first air outlet of the second movable member, and / or the second air outlet of the first movable member may have a different cross-sectional area to the second air outlet of the second movable member. Accordingly, each slot may be manufactured to a bespoke cross-sectional area to provide a desired output air profile during use of the attachment. This may improve performance of the attachment compared to the first and / or second outlets of the first movable member having the same cross-sectional area as the respective first and / or second outlets of the second movable member. For example, the first outlet of the movable member closest to the first side edge of the casing may have a greater cross-sectional area than the first outlet of the movable member closest to the second side edge of the casing. This may further tailor the characteristics of airflow emitted from the attachments. A width of the first and second air outlets may be in a range from 0.3 mm to 0.8 mm. This may help to generate useful airflow velocities for hair styling, without resulting in excessive pressures within the attachment. The casing may define an interior cavity. Each of the first and second movable members may comprise a plenum in fluid communication with the interior cavity. The first and second air outlets may be in fluid communication with the respective plenum. By providing the plenum, a smoother transition from the relatively large interior cavity of the casing to the comparatively small first and second air outlets is provided. This can help to maintain air pressure provided at the air inlet, to increase the velocity of airflow emitted from the first and second air outlets. The plenum may be defined by walls that extend from the interior cavity to the first and second air outlets and which are free from protrusions and recesses. This can help to maintain air pressure provided at the air inlet, to increase the velocity of airflow emitted from the first and second air outlets. The attachment may comprise first and second channels extending from the plenum to the respective first and second air outlets, wherein the channels define a smooth reduction in cross-sectional area from an aperture defining the plenum to the respective first or second air outlet. The closer to the first and second air outlets that airflow is restricted to the cross-sectional areas of the first and second air outlets, the faster the airflow accelerates through the first and second air outlets. Providing the plenum may therefore help to generate higher velocity airflow at the first and second air outlets compared to a movable member without the plenum. The smooth reduction in cross-sectional area is free of any step changes in cross-sectional area from the area of the aperture defining the plenum and the cross-sectional area of the respective first or second air outlet. This may help to prevent eddying within the plenum and / or the first and second channels. An area of an aperture defining the plenum may be at least 20 times greater than a cross-sectional area of each first air outlet, and at least 20 times greater than a cross-sectional area of each second air outlet. The aperture may have a width, the width extending orthogonal to the longitudinal axis of the attachment, in the region of from 10 mm to 20 mm, for example around 15 mm. A width of the first and second edge air outlets may be in a range from 0.3 mm to 0.8 mm. This may help to generate useful airflow velocities for hair styling, without resulting in excessive pressures within the attachment. The attachment may comprise a third movable member. The third movable member may be movably connected to the casing and disposed on an opposite side of the second movable member to the first movable member. The third movable member may be movable between third and fourth positions and may comprise first and second air outlets in fluid communication with the air inlet. The attachment may comprise a second auxiliary air outlet defined between the second movable member and the third movable member, the second auxiliary air outlet in fluid communication with the air inlet. In the first configuration, the third movable member may be in the third position and airflow may be directed in the first direction from the first and second air outlets and the second auxiliary air outlet of the third movable member to an exterior of the casing. In the second configuration, the third movable member may be in the fourth position and airflow may be directed in the second direction from the first and second air outlets and the second auxiliary air outlet of the third movable member to an exterior of the casing. Provision of a third movable member permits provision of more first and second air outlets, which may provide better airflow directionality across the attachment. This may also provide better haircare performance by the attachment, for example by emitting air more regularly across the attachment. The third movable member may be configured to be in the third position when the first and second movable members are in the first position, and in the fourth position when the first and second movable members are in the second position. The third movable member may have any of the features described with reference to the first and second movable members. The attachment may comprise further movable members comprising respective first and second air outlets and movable relative to the casing between two positions in the same way as described for the first, second and third movable members. In a second aspect, there is provided a haircare appliance comprising a handle unit and an attachment according to the first aspect. The attachment may be releasably attachable to the handle unit. Thus, the handle unit may provide multifunctionality, being usable with multiple different attachments. The handle unit may comprise an airflow generator, for providing an airflow to the air inlet of the attachment. This may provide a self-contained haircare appliance.

DETAILED DESCRIPTION A haircare appliance according to an example, generally designated 10, is shown schematically in Figure 1. The haircare appliance 10 comprises a handle unit 12, and an attachment 100 removably attachable to the handle unit 12. The handle unit 12 comprises a housing 14, an airflow generator 16, a heater 18, and a control unit 20, as can be seen schematically in Figure 2. The housing 14 is tubular in shape, and comprises an air inlet 22 through which an airflow is drawn into the housing 14 by the airflow generator 16, and an air outlet 24 through which the airflow is discharged from the housing 14. The airflow generator 16 is housed within the housing 14, and comprises an impeller 26 driven by an electric motor 28. The heater 18 is also housed within the housing 14, and comprises heating elements 30 to optionally heat the airflow. The control unit 20 comprises electronic circuitry for a user interface 32 and a control module 34. The user interface 32 is provided on an outer surface of the housing 14, and is used to power on and off the haircare appliance 10, to select a flow rate (for example high, medium and low), and to select an airflow temperature (for example hot, medium or cold). In the example of Figure 1, the user interface comprises a plurality of sliding switches, but other forms of user interface 32, for example buttons, dials or touchscreens, are also envisaged. The control module 34 is responsible for controlling the airflow generator 16, and the heater 18 in response to inputs from the user interface 32. For example, in response to inputs from the user interface 32, the control module 34 may control the power or the speed of the airflow generator 16 in order to adjust the airflow rate of the airflow, and the power of the heater 18 in order to adjust the temperature of the airflow. Various views of the attachment 100 are shown in Figures 1 and 3 to 11. The attachment 100 is open at one end and closed at the other end. An open end serves as an air inlet 102 into the attachment 100, with the air inlet 102 receiving airflow from the air outlet 24 of the handle unit 12 when attached in use. The attachment 100 comprises a fixed body 104, a linkage mechanism 195, and first 130, second 150 and third 170 movable members (which are collectively referred to as the movable members 130, 150, 170 herein, for brevity) each rotatably mounted to the fixed body 104 by the linkage mechanism 195. The movable members 130, 150, 170 are bristle beds and each support a respective plurality of bristles 132,152,172. The fixed body 104 defines an interior cavity 106, which acts as a main airflow path through the attachment 100. The fixed body 104 has a connection portion 108 for connection to the handle unit 12, with the connection portion 108 having a number of projections 110 which are receivable within corresponding recesses (not shown) formed on the handle unit 12 to ensure correct connection and alignment between the handle unit 12 and the attachment 100. The fixed body 104 is elongate, having a central longitudinal axis 101. The fixed body 104 is generally ovular in cross-section, as viewed end-on, and as best shown in Figures 4 and 8 to 11. A front face 112 of the fixed body defines an aperture 114 that permits fluid communication between the interior cavity 106 and an exterior of the fixed body 104. A rear face 116, opposite the front face 112, is closed. The front face 112 is connected to the rear face 116 by a first side wall 118 and a second side wall 120, at opposing sides of the fixed body 104 to one another. The first and second side walls 118, 120 extend in a direction along the longitudinal axis 101 between a first longitudinal end 125 and a second longitudinal end 126. Figure 4 is a section through the attachment 100, in a direction orthogonal to the longitudinal axis 101, in which the movable members 130, 150, 170 have been omitted for clarity. The attachment 100 comprises an inner wall 122 disposed substantially within the fixed body 104. The inner wall 122 is fixed in position relative to the fixed body 104 within the interior cavity 106. The inner wall 122 is elongate, extending from one end of the fixed body 104 to an opposing end. The inner wall 122 also extends between the first side wall 118 and the second side wall 120. The inner wall 122 comprises a first end portion 121 proximate the first side wall 118 and second end portion 123 proximate the second side wall 120. The first and second end portions 121, 123 each comprise a respective convex or curved surface 127, 129 respectively. The curved surfaces 127, 129 face towards the aperture 114. The fixed body 104 also comprises a first edge surface 117 adjacent to the first side wall 118, and a second edge surface 119 adjacent to the second side wall 120. The first and second edge surfaces 117, 119 generally face in the same direction as the front face 112 of the fixed body 104. The first and second edge surfaces 117, 119 are convexly curved. The first and second edge surfaces 117, 119 extend in a direction along the longitudinal axis 101. The linkage mechanism 195 comprises a pair of fixed members 196 disposed in the interior cavity 106 at opposing ends of the fixed body 104. Only one of the pair of fixed members 196 is shown in Figures 8 to 11. Each fixed member 196 is rigidly connected to the fixed body 104. Each fixed member 196 comprises a plurality of slots 198, each slot 198 configured to receive a respective linking rod 131, 151, 171. Each linking rod 131, 151, 171 is coupled to a respective one of the first, second and third movable members 130, 150, 170. Each linking rod 131, 151, 171 is configured to move within the respective slot 198, such that the first, second and third movable members 131, 151, 171 are movable between a first position, as shown in Figures 8 and 10, and a second position, as shown in Figures 9 and 11. The movable members 130, 150, 170 are arranged within the fixed body 104 adjacent to one another, with the plurality of bristles 132, 152, 172 of each movable member 130, 150, 170 protruding from the fixed body 104 via the aperture 114, as shown in Figure 3. The first movable member 130 is positioned between the second and third movable members 150, 170. In this example, each plurality of bristles 132, 152, 172 comprises two rows of bristles, each row extending parallel to one another along a length of the fixed body 104. The second movable member 150 is shown in cross-section in Figure 5, and comprises: a bristle support 153 from which the plurality of bristles 152 extend, a main body 154 rigidly connected to the bristle support 153 on an opposite side of the bristle support 153 from which the plurality of bristles 152 extend, and a pair of lugs 165. A first row of the plurality of bristles 152 on a first side of the second movable member 150 are hookshaped, whereas a second row of the plurality of bristles 152 on a second side of the second movable member 150 are loop-shaped. However, in other examples, one of the rows of the plurality of bristles 152 may be standard, straight bristles. In further examples, all of the plurality of bristles 152 may have the same shape. In still further examples, the bristles 152 may have any suitable shape for engaging with hair. The main body 154 is formed from glass-filled Nylon. The bristle support 153 is formed from a thermoplastic elastomer. Each of the lugs 165 comprises a connection point configured to receive a linking rod 151. The main body 154 has a first edge 154a and a second edge 154b on an opposite side of the main body 154 to the first edge 154a. An outer surface 153a of the bristle support 153, facing away from the main body 154, forms a convex arc. The main body 154 defines a plenum 155, a first channel 156, a second channel 157, a first outlet 158, and a second outlet 159. The first outlet 158 is defined in the first edge 154a of the main body 154 and the second outlet 159 is defined in the second edge 154b of the main body 154. The plenum 155 is located between the first outlet 158 and the second outlet 159. The first channel 156 fluidly connects the plenum 155 to the first outlet 158. The second channel 157 fluidly connects the plenum 155 to the second outlet 159. The plenum 155, first channel 156, second channel 157, first outlet 158, and second outlet 159 each extend along a length of the main body 154, and each have the same length in a direction along the length of the main body 154. The second movable member 150 comprises a first flow diverting member 160a and a second flow diverting member 160b. The first flow diverting member 160a is disposed at a first end of the second movable member 150, adjacent to the first outlet 158. The second flow diverting member 160b is disposed at a second end of the second movable member 150, opposed to the first end, and adjacent to the second outlet 159. The first and second flow diverting members 160a, 160b are formed integrally with the main body 154 of the second movable member 150. The first flow diverting member 160a has a different shape to the second flow diverting member 160b. The first flow diverting member 160a comprises a first flow surface 161a and a second flow surface 162a. The first flow surface 161a is disposed on a first side of the first flow diverting member 160a and the second flow surface 162a is disposed on a second, opposing side of the first flow diverting member 160a. The second flow surface 162a faces towards the plenum 155 and the first channel 156. The first flow surface 161a is concave, whereas the second flow surface 162a is convex. The second flow diverting member 160b comprises a first flow surface 161b and a second flow surface 162b. The first flow surface 161b is disposed on a first side of the second flow diverting member 160b and the second flow surface 162a is disposed on a second, opposing side of the second flow diverting member 160b. The second flow surface 162b faces towards the plenum 155 and the second channel 156. The first flow surface 161b is concave, whereas the second flow surface 162b is convex. The first movable member 130 is shown in cross-section in Figure 6 and comprises: a bristle support 133 from which the plurality of bristles 132 extend, a main body 134 rigidly connected to the bristle support 133 on an opposite side of the bristle support 133 from which the plurality of bristles 132 extend, and a pair of lugs 145. The main body 134 of the first movable member 130 is symmetrical about a central plane 130a of the first movable member 130. The bristles 132 of both rows of the plurality of bristles 132 of the first movable member 130 are loop-shaped. However, in other examples, one or both of the rows of bristles 132 may have differently shaped bristles 132. In still further examples, the bristles 132 may have any suitable shape for engaging with hair. The main body 134 is formed from glass-filled Nylon. The bristle support 133 is formed from a thermoplastic elastomer. Each of the lugs 145 comprises a connection point configured to receive a linking rod 131. The main body 134 has a first edge 134a and a second edge 134b on an opposite side of the main body 134 to the first edge 134a. An outer surface 133a of the bristle support 133, facing away from the main body 134, forms a convex arc. The main body 134 defines a plenum 135, a first channel 136, a second channel 137, a first outlet 138, and a second outlet 139. The first outlet 138 is defined in the first edge 134a of the main body 134 and the second outlet 139 is defined in the second edge 134b of the main body 134. The plenum 135 is located between the first outlet 138 and the second outlet 139. The first channel 136 fluidly connects the plenum 135 to the first outlet 138. The second channel 137 fluidly connects the plenum 135 to the second outlet 139. The plenum 135, first channel 136, second channel 137, first outlet 138, and second outlet 139 each extend along a length of the main body 134, and each have the same length in a direction along the length of the main body 134. The first movable member 130 comprises a first flow diverting member 140a and a second flow diverting member 140b. The first flow diverting member 140a is disposed at a first end of the first movable member 130, adjacent to the first outlet 138. The second flow diverting member 140b is disposed at a second end of the first movable member 130, opposed to the first end, and adjacent to the second outlet 139. The first and second flow diverting members 140a, 140b are formed integrally with the main body 134 of the first movable member 130. The first flow diverting member 140a has the same shape as, and is a mirror image of, the second flow diverting member 140b, about the central plane 130a. The first flow diverting member 140a comprises a first flow surface 141a and a second flow surface 142a. The first flow surface 141a is disposed on a first side of the first flow diverting member 140a and the second flow surface 142a is disposed on a second, opposing side of the first flow diverting member 140a. The second flow surface 142a faces towards the plenum 135 and the first channel 136. The first flow surface 141a is concave, whereas the second flow surface 142a is convex. The second flow diverting member 140b comprises a first flow surface 141b and a second flow surface 142b. The first flow surface 141b is disposed on a first side of the second flow diverting member 140b and the second flow surface 142a is disposed on a second, opposing side of the second flow diverting member 140b. The second flow surface 142b faces towards the plenum 135 and the second channel 136. The first flow surface 141b is concave, whereas the second flow surface 142b is convex. Figure 7 shows a cross-section of the third movable member 170. The third movable member 170 is a mirror image of the second movable member 150, taken about a plane extending along the longitudinal axis 101 of the attachment 100. The third movable member 170 will therefore not be described in detail herein. Like features have the same reference number, but increased by 20 compared to the second movable member 150. The bristle support 133, 153, 173 and the main body 134, 154, 174 of each movable member 130, 150, 170 are elongate, as best shown in Figures 1 and 3. The pair of lugs of each movable member 130, 150, 170 extend from opposing ends of the respective main body 134, 154, 174, in an opposite direction to a direction in which the respective plurality of bristles 132, 152, 172 extend, and are rigidly attached to the respective main body 134, 154, 174. The attachment 100 is shown in cross-section in Figures 5 to 9. The movable members 130, 150, 170 are positioned within the fixed body 104 of the attachment 100 adjacent to one another such that the bristle supports 133, 153, 173 and the main bodies 134, 154, 174 extend in a direction along the length of the aperture 114. Each plenum 135, 155, 175 is open to the interior cavity 106 via a plenum aperture 135a, 155a, 175a. The first and second outlets 138, 158, 178, 139, 159, 179 each have a width of around 0.5mm in this example. It will be appreciated that in other examples, the first outlets 138, 158, 178 may have different widths to one another, and the second outlets 139, 159, 179 may have different widths to one another. In an example, the first outlet 158 of the second movable member 150 has a greater width than a width of the first and second outlets 138, 139 of the first movable member 130. It will be appreciated that the first and second outlets 138, 158, 178, 139, 159, 179 in one movable member 130, 150, 170 may have different widths to one another. In an example, the first outlet 158 of the second movable member 150 and the second outlet 179 of the third movable member 170 each have a width of 0.6mm, and the second outlet 159 of the second movable member 150 and the first outlet 178 of the third movable member 170 each have a width of 0.4mm. In this example, the plenum apertures 135a, 155a, 175a each have a width W of around 12mm. The first and second channels 136, 156, 176, 137, 157, 177 define a smooth transition in width from the plenum apertures 135a, 155a, 175a to the respective first and second outlets 138,158, 178,139,159,179, free of any step changes in width. The movable members 130, 150, 170 are arranged within the fixed body 104 so that the first edge 154a of the second movable member 150 is adjacent to the first side wall 118 of the fixed body 104, and the second edge 174b of the third movable member 170 is adjacent to the second side wall 120 of the fixed body 104. The second edge 154b of the second movable member 150 is adjacent to the first edge 134a of the first movable member 130. The second edge 134b of the first movable member 130 is adjacent to the first edge 174a of the third movable member 170. The attachment 100 further comprises auxiliary outlets 190,191, 192, 193 as a result of the arrangement of the movable members 130, 150, 170 within the fixed body 104. A first auxiliary outlet 190 is defined between the first side wall 118 of the fixed body 104 and the first edge 154a of the second movable member 150. A second auxiliary outlet 191 is defined between the second edge 154b of the second movable member 150 and the first edge 134a of the first movable member 130. A third auxiliary outlet 192 is defined between the second edge 134b of the first movable member 130 and the first edge 174a of the third movable member 170. A fourth auxiliary outlet 193 is defined between the second edge 174b of the third movable member 170 and the second side wall 120 of the fixed body 104. Each of the auxiliary outlets 190-193 are fluidly coupled to the interior cavity 106. The first flow diverting member 160a of the second movable member 150 is disposed adjacent to the first end portion 121 of the inner wall 122. A first auxiliary channel 220 is defined between the first end portion 121 and the first flow diverting member 160a of the second movable member 150. The first auxiliary channel 220 fluidly connects the interior cavity 106 to the first auxiliary outlet 190. The second flow diverting member 160b of the second movable member 150 is disposed adjacent to the first flow diverting member 140a of the first movable member 130. A second auxiliary channel 221 is defined between the second flow diverting member 160b of the second movable member 150 and the first flow diverting member 140a of the first movable member 130. The second auxiliary channel 221 fluidly connects the interior cavity to the second auxiliary outlet 191. The second flow diverting member 140b of the first movable member 130 is disposed adjacent to the first flow diverting member 180a of the third movable member 170. A third auxiliary channel 222 is defined between the second flow diverting member 140b of the first movable member 130 and the first flow diverting member 180a of the third movable member 170. The third auxiliary channel 222 fluidly connects the interior cavity to the third auxiliary outlet 192. The second flow diverting member 180b of the third movable member 170 is disposed adjacent to the second end portion 123 of the inner wall 122. A fourth auxiliary channel 223 is defined between the second flow diverting member 180b and the second end portion 123. The fourth auxiliary channel 223 fluidly connects the interior cavity 106 to the fourth auxiliary outlet 193. The respective pairs of lugs 145, 165, 185 are connected to the respective slot 198 of the fixed member 196 by a respective linking rod 131, 151, 171 such that the movable members 130, 150, 170 are rotatable and movable relative to the fixed body 104 between a first position, as shown in Figures 8 and 10, and a second position, as shown in Figures 9 and 11. In the first position, the movable members 130, 150, 170 are generally inclined towards the first side wall 118 of the fixed body 104. This causes the relative positions of the flow diverting members 140a, 140b, 160a, 160b, 180a, 180b, the respective first and second outlets 138, 139, 158, 159, 178, 179, and the first and second end portions 121, 123 to change. In the first position, the first outlet 158 of the second movable member 150 faces towards the concave surface 127 of the first end portion 121 of the inner wall 122. The second outlet 159 of the second movable member 150 faces generally towards an exterior of the fixed body 104. The first outlet 138 of the first movable member 130 faces towards the first flow surface 161b of the second flow diverting member 160b of the second movable member 150. The position of the first flow surface 141b of the first flow diverting member 140a of the first movable member 130 is offset below the position of the first flow surface 161b of the second flow diverting member 160b of the second movable member 150. The second outlet 139 of the first movable member 130 faces generally towards an exterior of the fixed body 104. The first outlet 178 of the third movable member 170 faces towards the first flow surface 141b of the second flow diverting member 140b of the first movable member 130. The position of the first flow surface 181b of the first flow diverting member 180a of the third movable member 170 is offset below the position of the first flow surface 141b of the second flow diverting member 140b of the first movable member 130. The second outlet 179 of the third movable member 170 faces generally towards an exterior of the fixed body 104. In this first position, the auxiliary outlets 190-193 remain open to create a direct airflow path from the interior cavity 106 to an exterior of the fixed body 104. In the second position, the movable members 130, 150, 170 are generally inclined towards the second side wall 120 of the fixed body 104. This causes the relative positions of the flow diverting members 140a, 140b, 160a, 160b, 180a, 180b, the respective first and second outlets 138, 139, 158, 159, 178, 179, and the first and second end portions 121, 123 to change. In this second position, the first outlet 158 of the second movable member 150 faces generally towards an exterior of the fixed body 104. The second outlet 159 of the second movable member 150 faces towards the first flow surface 141a of the first flow diverting member 140a of the first movable member 130. The first outlet 138 of the first movable member 130 faces generally towards an exterior of the fixed body 104. The position of the first flow surface 161b of the second flow diverting member 160b of the second movable member 150 is offset below the position of the first flow surface 141a of the first flow diverting member 140a of the first movable member 130. The second outlet 139 of the first movable member 130 faces towards the first flow surface 181a of the first flow diverting member 180a of the third movable member 170. The position of the first flow surface 141b of the second flow diverting member 140b of the first movable member 130 is offset below the position of the first flow surface 181a of the first flow diverting member 180a of the third movable member 170. The first outlet 178 of the third movable member 170 faces generally towards an exterior of the fixed body. The second outlet 179 of the third movable member 170 faces towards the concave surface 129 of the second end portion 123 of the inner wall 122. In this second position, the auxiliary outlets 190-193 remain open to create a direct airflow path from the interior cavity 106 to an exterior of the fixed body 104. Figures 10 and 11 show the movable members 130, 150, 170 in the respective first and second positions, with the haircare appliance 10 in use. With the haircare appliance 10 powered on at the user interface 32, the control module 34 causes the airflow generator 16 to generate airflow, which is drawn into the housing 14 via the air inlet 22 and expelled into the interior cavity 106 of the fixed body 104 of the attachment 100 via the air outlet 24 and the air inlet 102 of the attachment 100. As a user draws the pluralities of bristles 132, 152, 172 through hair, tension acting on the bristles 132, 152, 172 causes the movable members 130, 150, 170 to move to either the first position or the second position. If the tension acts in a direction towards the first side wall 118 of the fixed body 104, as denoted by the arrow T1 in Figure 10, the movable members 130, 150, 170 are moved to the first position, as shown in Figure 10. If the tension acts in a direction towards the second side wall 120 of the fixed body 104, as denoted by the arrow T2 in Figure 11, the movable members 130, 150, 170 are moved to the second position, as shown in Figure 11. In use, with the movable members 130, 150, 170 in the first position, the airflow exits the interior cavity 106 to an exterior of the fixed body 104 in a direction towards the second side wall 120 of the fixed body 104, and thus along the hair through which the pluralities of bristles 132, 152, 172 are being drawn. Air is emitted from the fixed body 104 via each of the respective first and second outlets 138, 139, 158, 159, 178, 179 of the movable members 130, 150, 170 and via each of the auxiliary outlets 190-193, as denoted by the solid arrows in Figure 10. Air flows along a first airflow path 201a directly from the interior cavity 106 and through the first auxiliary channel 220. In addition, air flows along a second airflow path 201b from the interior cavity 106, through the plenum 155 of the second movable member 150, through the first channel 156 and out of the first outlet 158 of the second movable member 150. Air exits the first outlet 158 of the second movable member 150 and is entrained by the air passing through the first auxiliary channel 220. The air passing through the first auxiliary channel 220 is turned by the concave surface 127 of the first end portion 121 of the inner wall 122, such that the airflow 201 emitted from the first auxiliary outlet 190 is directed over the outer surface 153a of the bristle support 153 of the second movable member 150. The arcuate shape of the outer surface 153a of the bristle support 153 of the second movable member 150 has a Coanda effect on the airflow 201, helping the airflow 201 to follow the outer surface 153a of the bristle support 153 of the second movable member 150. Air flows along a third airflow path 202a from the interior cavity 106, through the plenum 155 of the second movable member 150, through the second channel 157 and out of the second outlet 159 of the second movable member. The position of the second outlet 159 means that airflow exiting the second outlet 159 is directed towards the outer surface 133a of the bristle support 133 of the first movable member 130. Air flows along a fourth airflow path 202b from the interior cavity 106, through the second auxiliary channel 221 and out of the second auxiliary outlet 191. Along the fourth airflow path 202b, the air is turned first by the concave first airflow surface 141a of the first airflow diverting member 140a of the first movable member 130, and then turned by the concave first airflow surface 161b of the second airflow diverting member 160b of the second movable member 150, such that airflow exiting the second auxiliary outlet 191 is directed towards the outer surface 133a of the bristle support 133 of the first movable member 130. Air also flows along a fifth airflow path 202c from the interior cavity 106, through the first channel 136 of the first movable member 130, out of the first outlet 138 of the first movable member 130, and into the second auxiliary channel 221. Air exiting the first outlet 138 is entrained by the airflow passing through the second auxiliary channel 221 and is turned by the concave first airflow surface 161b of the second airflow diverting member 160b of the second movable member 150. Thus, airflow exiting the second outlet 159 of the second movable member 150 and airflow exiting the second auxiliary outlet 191 is entrained into a single airflow 202 emitted to the exterior of the fixed body 104 and across the outer surface 133a of the bristle support 133 of the first movable member 130. The arcuate shape of the outer surface 133a of the bristle support 133 of the first movable member 130 has a Coanda effect on the airflow 202, helping the airflow 202 to follow the outer surface 133a of the bristle support 133 of the first movable member 130. Air flows along a sixth airflow path 203a from the interior cavity 106, through the plenum 135 of the first movable member 130, through the second channel 137 and out of the second outlet 139 of the first movable member 130. The position of the second outlet 139 means that airflow exiting the second outlet 139 is directed towards the outer surface 173a of the bristle support 173 of the third movable member 170. Air flows along a seventh airflow path 203b from the interior cavity 106, through the third auxiliary channel 222 and out of the third auxiliary outlet 192. Along the seventh airflow path 203b, the air is turned first by the concave first airflow surface 181a of the first airflow diverting member 180a of the third movable member 170, and then turned by the concave first airflow surface 141b of the second airflow diverting member 140b of the first movable member 130, such that airflow exiting the third auxiliary outlet 192 is directed towards the outer surface 173a of the bristle support 173 of the third movable member 170. Air also flows along an eighth airflow path 203c from the interior cavity 106, through the first channel 176 of the third movable member 170, out of the first outlet 178 of the third movable member 170, and into the third auxiliary channel 222. Air exiting the first outlet 178 is entrained by the airflow passing through the third auxiliary channel 222 and is turned by the concave first airflow surface 141b of the second airflow diverting member 140b of the first movable member 130. Thus, airflow exiting the second outlet 139 of the first movable member 130 and airflow exiting the third auxiliary outlet 192 is entrained into a single airflow 203 emitted to the exterior of the fixed body 104 and across the outer surface 173a of the bristle support 173 of the third movable member 170. The arcuate shape of the outer surface 173a of the bristle support 173 of the third movable member 170 has a Coanda effect on the airflow 203, helping the airflow 203 to follow the outer surface 173a of the bristle support 173 of the third movable member 170. In addition, air flows along a ninth airflow path 204a from the interior cavity 106, through the plenum 175 of the third movable member 170, through the second channel 177 and out of the second outlet 179 of the third movable member 170. The position of the second outlet 179 means that airflow exiting the second outlet 179 is directed towards the second edge surface 119 of the fixed body 104. Air also flows along a tenth airflow path 204b from the interior cavity 106, through the fourth auxiliary channel 223, and out through the fourth auxiliary outlet 194. Airflow exiting the second outlet 179 of the third movable member 170 and airflow exiting the fourth auxiliary outlet 194 are entrained into a single airflow 204 emitted to the exterior of the fixed body 104 and across the second edge surface 119 of the fixed body 104. The curved shape of the second edge surface 119 has a Coanda effect on the airflow 204, helping the airflow 204 to follow the second edge surface 119 of the fixed body 104. In this way, the airflow exiting the fixed body 104 flows generally in the same direction (towards the second sidewall 120) to an exterior of the fixed body 104 when the movable members 130, 150, 170 are in the first position. In use, with the movable members 130, 150, 170 in the second position, the airflow exits the interior cavity 106 to an exterior of the fixed body 104 in a direction towards the first side wall 180 of the fixed body 104, and thus along the hair through which the pluralities of bristles 132, 152, 172 are being drawn. Air is emitted from the fixed body 104 via each of the respective first and second outlets 138, 139, 158, 159, 178, 179 of the movable members 130, 150, 170 and via each of the auxiliary outlets 190-193, as denoted by the solid arrows in Figure 11. Air flows along a first airflow path 211a directly from the interior cavity 106, through the first auxiliary channel 220 and out through the first auxiliary outlet 190. Air exiting the first auxiliary outlet 190 is directed towards the first edge surface 117. In addition, air flows along a second airflow path 211b from the interior cavity 106, through the plenum 155 of the second movable member 150, through the first channel 156 and out of the first outlet 158 of the second movable member 150. The position of the first outlet 158 means that airflow exiting the second outlet 158 is directed towards the first edge surface 117 of the fixed body 104. Airflow exiting the first outlet 158 of the second movable member 150 and airflow exiting the first auxiliary outlet 190 are entrained into a single airflow 211 emitted to the exterior of the fixed body 104 and across the first edge surface 117 of the fixed body 104. The curved shape of the first edge surface 117 has a Coanda effect on the airflow 211, helping the airflow 211 to follow the second edge surface 117 of the fixed body 104. Air flows along a third airflow path 212a from the interior cavity 106, through the plenum 155 of the second movable member 150, through the second channel 157, out of the second outlet 159 of the second movable member 150, and into the second auxiliary channel 221. Air flows along a fourth airflow path 212b from the interior cavity 106, through the second auxiliary channel 221 and out of the second auxiliary outlet 191. Along the fourth airflow path 212b, the air is turned first by the concave first airflow surface 161b of the second airflow diverting member 160b of the second movable member 150, and then turned by the concave first airflow surface 141a of the first airflow diverting member 140a of the first movable member 130, such that airflow exiting the second auxiliary outlet 191 is directed towards the outer surface 153a of the bristle support 153 of the second movable member 150. Air exiting the second outlet 159 of the second movable member 150 is entrained by the airflow passing through the second auxiliary channel 221 and is turned by the concave first airflow surface 141b of the first airflow diverting member 140a of the first movable member 130. Air also flows along a fifth airflow path 212c from the interior cavity 106 through the plenum 135 of the first movable member 130, through the first channel 136 and out of the first outlet 138 of the first movable member 130. The position of the first outlet 138 means that airflow exiting the first outlet 138 is directed towards the outer surface 153a of the bristle support 153 of the second movable member 150. Thus, airflow exiting the first outlet 138 of the first movable member 130 and airflow exiting the second auxiliary outlet 191 is entrained into a single airflow 212 emitted to the exterior of the fixed body 104 and across the outer surface 153a of the bristle support 153 of the second movable member 150. The arcuate shape of the outer surface 153a of the bristle support 143 of the second movable member 150 has a Coanda effect on the airflow 212, helping the airflow 212 to follow the outer surface 153a of the bristle support 153 of the second movable member 150. Air flows along a sixth airflow path 213a from the interior cavity 106, through the plenum 135 of the first movable member 130, through the second channel 137, out of the second outlet 139 of the first movable member 130, and into the third auxiliary channel 222. Air flows along a seventh airflow path 213b from the interior cavity 106, through the third auxiliary channel 222 and out of the third auxiliary outlet 192. Along the seventh airflow path 213b, the air is turned first by the concave first airflow surface 141b of the second airflow diverting member 140b of the first movable member 130, and then turned by the concave first airflow surface 181a of the first airflow diverting member 180a of the third movable member 170, such that airflow exiting the third auxiliary outlet 192 is directed towards the outer surface 133a of the bristle support 133 of the first movable member 130. Air exiting the second outlet 139 of the first movable member 130 is entrained by the airflow passing through the third auxiliary channel 222 and is turned by the concave first airflow surface 181b of the first airflow diverting member 180a of the third movable member 170. Air also flows along an eighth airflow path 213c from the interior cavity 106 through the plenum 175 of the third movable member 170, through the first channel 176 and out of the first outlet 178 of the third movable member 170. The position of the first outlet 178 means that airflow exiting the first outlet 178 is directed towards the outer surface 133a of the bristle support 133 of the first movable member 130. Thus, airflow exiting the first outlet 178 of the third movable member 170 and airflow exiting the third auxiliary outlet 192 is entrained into a single airflow 213 emitted to the exterior of the fixed body 104 and across the outer surface 133a of the bristle support 133 of the first movable member 130. The arcuate shape of the outer surface 133a of the bristle support 133 of the first movable member 130 has a Coanda effect on the airflow 213, helping the airflow 213 to follow the outer surface 133a of the bristle support 133 of the first movable member 130. Air flows along a ninth airflow path 214a from the interior cavity 106, through the plenum 175 of the third movable member 170, through the second channel 177, out of the second outlet 179 of the third movable member 170, and into the fourth auxiliary channel 223. In addition, air flows along a tenth airflow path 214b directly from the interior cavity 106 and through the fourth auxiliary channel 222. Air exiting the second outlet 179 of the third movable member 170 is entrained by the air passing through the fourth auxiliary channel 223. The air passing through the fourth auxiliary channel 223 is turned by the concave surface 129 of the second end portion 123 of the inner wall 122, such that the airflow 214 emitted from the fourth auxiliary outlet 193 is directed over the outer surface 173a of the bristle support 173 of the third movable member 170. The arcuate shape of the outer surface 173a of the bristle support 173 of the third movable member 180 has a Coanda effect on the airflow 214, helping the airflow 214 to follow the outer surface 173a of the bristle support 173 of the third movable member 170. In this way, the airflow exiting the fixed body 104 flows generally in the same direction (towards the first sidewall 118) to an exterior of the fixed body 104 when the movable members 130,150,170 are in the second position. Accordingly, in use, airflow is emitted from the attachment 100 in opposing directions, depending on the position of the movable members 130, 150, 170. This may assist a user in drying hair in different directions, for example hair on opposing sides of the head. By ensuring that the airflow attaches to an outer surface of the attachment 100 in the first and second directions, the air can flow substantially parallel to the hair as the user moves the attachment through the hair. This means that the airflow does not substantially disturb the user’s hair style, and a smooth finish can be achieved. Although the attachment 100 described herein comprises three movable members 130, 150, 170, it will be appreciated that attachments with two or more movable members fall within the scope of the application. For example, the first movable member could be omitted, and the second and third movable members could be arranged within the fixed body such that, in the first and second positions, airflow is emitted from the attachment in respective opposing directions. Although the attachment 100 described herein comprises a linkage mechanism 195 comprising a pair of fixed members 196 having a plurality of slots configured to received linking rods coupled to the first, second and third movable members 130, 150, 170, it will be appreciated that in other examples, any other linkage mechanism could be used which enables the movable members 130, 150, 170 to move between the first and second positions. For example, the linkage mechanism may comprise a pair of linkages which are movably connected to the fixed body such that the linkages are movable between a first position and a second position. In such an example, the movable members may be pivotable coupled to the linkages. Although the attachment 100 described herein comprises flow diverting members to divert airflow, with the flow diverting members formed as part of the movable members 130, 150, 170, it will be appreciated that in other examples, the flow diverting members may be formed separately from the movable members. For example, the flow diverting members may be formed as separate vanes or passages which are configured to direct airflow from the first and second outlets and the auxiliary outlets in the first and second directions when the movable members are in the first and second positions, respectively. Although in the forgoing description, elements of the apparatus may be referred to by numbering such as “first”, “second”, “third”, etc., it will be appreciated that this is only to provide a distinction between different elements and is not limiting. It will therefore be appreciated that elements can be referred to by different numbering. For example, the first movable member may be referred to as the second movable member, and the second movable member may be referred to as the first movable member. It will be understood that the invention is not limited to the embodiments above-described and various modifications and improvements can be made without departing from the concepts described herein. Except where mutually exclusive, any of the features may be employed separately or in combination with any other features and the disclosure extends to and includes all combinations and sub-combinations of one or more features described herein.
