Description

The present invention relates to an attachment for a hair care device and a hair care device including the attachment.

Hair care devices may include attachments for wrapping hair to create curls. Air may be released from the attachment to encourage hair to wrap around the attachment.

The present invention provides an attachment for a hair care device. The attachment includes an inlet for receiving the airflow, a plurality of outlets from which the airflow is emitted, and one or more members movable between a first position and a second position, the member being movable between a first position and a second position. When the member is in the first position, airflow is emitted from the outlet in a clockwise direction, and when the member is in the second position, airflow is emitted from the outlet in a counterclockwise direction.

The outlet may include a first outlet in which the airflow is emitted in a clockwise direction and a second outlet in which the airflow is emitted in a counterclockwise direction, and the member is in the first position. The airflow to the second outlet may be occluded when in the second position and the airflow to the first outlet may be occluded when in the second position.

Each of the members may rotate between a first position and a second position.

Each of the members may rotate about a different respective axis.

Each outlet may include a slot extending substantially along the length of the attachment.

The air flow may be emitted from each outlet substantially tangentially to the outer surface of the attachment.

The airflow emitted from each outlet may be drawn to the outer surface of the attachment.

The attachment may have a generally cylindrical shape.

The attachment may have a longitudinal axis and each outlet may include a slot extending parallel to the longitudinal axis.

The attachment may include an inner sleeve and an outer sleeve, the inner sleeve may include a plurality of openings, and the outer sleeve may include a plurality of first openings and a plurality of second openings. But that's fine. The member is then one of the inner and outer sleeves and rotates relative to the other of the inner and outer sleeves. When the member is in the first position, the opening in the inner sleeve is aligned with the first opening in the outer sleeve and airflow is emitted in a clockwise direction. When the member is in the second position, the opening in the inner sleeve is aligned with the second opening in the outer sleeve and airflow is emitted in a counterclockwise direction.

Each movable member may include a louver and the attachment may include multiple columns. Each louver then contacts a first column when in a first position and a different second column when in a second position.

Each louver may contact a first column along a first edge of the louver when in the first position, and a first outlet may be made along a second edge of the louver. It's okay. Each louver may additionally contact the second column along the second edge when in the second position, and a second outlet may be created along the first edge. Good too. Airflow is then emitted from the first outlet in a clockwise direction and airflow is emitted from the second outlet in a counterclockwise direction.

The attachment may include a user-operated selector for moving the member between a first position and a second position.

The selector may include a dial that rotates to move the member between a first position and a second position.

The selector may be latched and may have two stable positions corresponding to a first position and a second position of the member.

The invention further provides a hair care device. The hair care device includes a blower for generating an air flow, a plurality of outlets from which the air flow is emitted, and one or more members movable between a first position and a second position, the member being movable between a first position and a second position. When the member is in the first position, airflow is emitted from the outlet in a clockwise direction, and when the member is in the second position, airflow is emitted from the outlet in a counterclockwise direction.

Embodiments will now be described, by way of example only, with reference to the accompanying drawings.

The hair care device 10 of FIGS. 1 to 3 includes a handle unit 20 and an attachment 100 that is removably attachable to the handle unit 20.

The handle unit 20 includes a housing 30, a blower 40, a heater 50, and a control unit 60.

The housing 30 is tubular in shape and includes an inlet 31 through which airflow is drawn into the housing 30 by a blower 40 and an outlet 32 through which the airflow is discharged from the housing 30. The blower 40 is housed within the housing 30 and includes a fan 41 driven by an electric motor 42. A heater 50 is also housed within the housing 30 and includes a heating element 51 for optionally heating the air stream.

The control unit 60 includes a user control section 61 and a control module 62.

The user control unit 61 is provided on the surface of the housing 30 and is used to turn on/off the power of the hair care device 10, select a flow rate (e.g., high, medium, low), and select an air temperature (e.g., hot, hot, cold). used for. In this example, each of the user controls 61 includes a slide switch. However, other forms of user controls such as buttons, dials or touch screens may be used.

Control module 62 serves to control blower 40 and heater 50 in response to input from user control 61 . For example, in response to input from a user control, control module 62 controls the power or speed of blower 40 to adjust the flow rate of the airflow, and the power or speed of heater 50 to adjust the temperature of the airflow. Power may also be controlled.

Referring now to FIGS. 4-8, attachment 100 includes a barrel 110 and a dial 120. As shown in FIGS.

Barrel 110 is cylindrical in shape, open at one end and closed at the other end. The open end serves as the entrance 111 to the interior 112 of the barrel 110. A plurality of outlets 113 are formed around the sides of the barrel. Each outlet 113 includes a slot extending along the length of the barrel 110, and the outlets 113 are evenly spaced about the longitudinal axis 114 of the barrel 110.

Barrel 110 includes an inner sleeve 140, an outer sleeve 150, and a plurality of slats 160. Inner sleeve 140 and outer sleeve 150 each have a cylindrical shape. Inner sleeve 140 is received within outer sleeve 150 and includes a plurality of slots 141 extending along the length of inner sleeve 140 . In the particular example shown, inner sleeve 140 includes five slots 141.

Outer sleeve 150 includes a plurality of openings 151 arranged in columns extending along the length of outer sleeve 150. More specifically, the openings 151 are arranged in pairs of evenly spaced columns 152, 153 around the outer sleeve 150. Again, in the particular example shown, outer sleeve 150 comprises five pairs of columns 152, 153. Each pair of columns 152, 153 is separated by a spine 154.

Each of the slats 160 is attached to one of the spines 154 of the outer sleeve 150, such as by a snap fit. Each slat 160 extends on either side of the spine 154 and overlies each column of openings 152, 153. The edges of the slats 160 are radially spaced apart from the outer sleeve 150 to form two slots 113a, 113b extending along the length of the barrel 110 between the slats 160 and the outer sleeve 150. Each of the slots 113a, 113b defines an outlet 113 of the barrel 110.

Inner sleeve 140 is movable relative to outer sleeve 150. More specifically, inner sleeve 140 rotates relative to outer sleeve 150 about longitudinal axis 114 of barrel 110. Inner sleeve 140 is movable between a first position and a second position. In the first position shown in FIG. 7(a), each of the slots 141 of the inner sleeve 140 is aligned with the column 152 of the first opening of the outer sleeve 140. In the second position of FIG. 7(b), each of the slots 141 of the inner sleeve 140 is aligned with the column 153 of the second opening of the outer sleeve 140.

In use, when the attachment 100 is attached to the handle unit 20, the airflow generated by the handle unit 20 enters the interior 112 of the barrel 110 via the inlet 111. From there, the airflow travels radially outward through slots 141 in inner sleeve 140. The airflow then passes through opening 151 in outer sleeve 150. More specifically, the airflow passes through either the first opening column 152 or the second opening column 153 of the outer sleeve 150, depending on the position of the inner sleeve 140. When the inner sleeve 140 is in the first position (FIG. 7(a)), airflow passes through the columns 152 of each first opening. The airflow is then redirected by the slats 160 in a clockwise direction. As a result, airflow is emitted from the barrel 110 in a clockwise direction. When the inner sleeve 150 is in the second position (FIG. 7(b)), airflow passes through the columns 153 of each second opening. The airflow is then redirected in a counterclockwise direction by the slats 160 and the airflow is emitted from the barrel 110 in a counterclockwise direction. Therefore, by changing the position of the inner sleeve 150, the direction of airflow emitted from the barrel 110 can be changed from clockwise to counterclockwise.

A dial 120 is provided at the top of the barrel 110 and is attached to the inner sleeve 140 (by screws 170 in this example). Dial 120 can be used to move inner sleeve 140 between a first position and a second position. For example, as shown in FIG. 8, the user may squeeze and twist or rotate dial 120 to move the inner sleeve between two positions. As a result, the user can change the direction in which the airflow is emitted from the barrel 110. More specifically, the user can select whether the airflow is emitted in a clockwise or counterclockwise direction.

According to the hair care device 10 described above, the user can change the direction of the airflow emitted from the attachment 100. In particular, by rotating the dial 120 on the top of the attachment 100, the user can select either clockwise or counterclockwise airflow. Thus, the direction of airflow can be changed without switching or changing attachments.

The airflow emitted from the outlet 113 is attracted to the curved surface of the barrel 110 by the Coanda effect. As a result, hair presented to attachment 100 is drawn to and wrapped around barrel 110. Hair care device 10 can thus be used to curl hair, with the direction of the curl being determined by the direction of the airflow. By providing a single attachment 100 that can send both clockwise and counterclockwise airflow, users can quickly and conveniently change the direction in which curls are formed.

The change in airflow direction is effected by movement of the inner sleeve 140 relative to the outer sleeve 150. However, as explained below, changing the direction of the airflow may also be effected by other means.

9 to 11 show a further attachment 200, comprising a barrel 210 and a dial 220, similar to the attachment of FIGS. 4 to 7.

Barrel 210 is again generally cylindrical in shape, open at one end and closed at the other end. The open end serves as an inlet 211 to the interior 212 of the barrel 210, with a plurality of outlets 213 formed along the sides of the barrel 210. Each outlet 213 includes a slot, and the outlets 213 are evenly spaced about the longitudinal axis of the barrel 210.

Barrel 210 includes an inner sleeve 240, a plurality of louvers 250, and a knob 260.

The inner sleeve 240 has a generally cylindrical shape, and is open at the lower end and closed at the upper end. A plurality of slots 241 extend along the length of sleeve 240. Slot 241 is relatively wide, so inner sleeve 240 may be considered to have columns 242 extending upwardly from the bottom of sleeve 240 to the top. In the particular example shown, the inner sleeve includes five slots 241 and five columns 242.

Each of the louvers 250 covers a respective slot 241 in the inner sleeve 240. The upper end of each louver 250 is pivotally attached to the top of the inner sleeve 240. The lower end of each louver includes a pin or foot 251 that is received within a slot 221 of dial 220. Each of the louvers 250 pivots between a first position and a second position. The pivot point of each louver 250 is offset from the longitudinal axis 214 of barrel 210. This is perhaps best seen in FIG. 10, where it can be seen that each louver 250 is pivotally connected to the inner sleeve 240 at a center-offset location 243. As a result, each louver 250 contacts the first column 242a of the sleeve 240 along the first edge 250a of the louver 250 when in the first position, as shown in FIG. 11(a). A gap or slot 213a is then created between the louver 250 and the inner sleeve 240 along the second edge 250b of the louver 250. As shown in FIG. 11(b), when in the second position, each louver 250 contacts the second column 242b of the sleeve 240 along the second edge 250b of the louver 250, and A gap or slot 213b is created between the inner sleeve 240 and along the first edge 250a. Each of the slots 213a, 213b defines an outlet 213 of the barrel 210. As can be seen in FIG. 11, when the louver 250 is in the first position (FIG. 11(a)), airflow is emitted from the barrel 210 in a clockwise direction, and when the louver 250 is in the second position (FIG. 11(b) )), the airflow is emitted in a counterclockwise direction.

Each column 242 may include a sealing element that engages a first edge 250a of the louver 250 when the louver 250 is in the first position and when the louver 250 is in the second position. The second edge 250b of the louver 250 is engaged with the second edge 250b of the louver 250. As a result, leakage of airflow from between the edges 250a, 250b of the louver 250 and the column 242 is suppressed. The sealing element may include a compressible material, which allows the sealing element to deform and provide an effective seal between the column 242 and the louvers 250.

Each of the louvers 250 includes a vane 252 that extends circumferentially around the inner surface of the louver 250. As the airflow moves from the inlet 211 to each of the outlets 213 of the barrel 210, the vanes 252 direct the airflow from a generally vertical direction (i.e., parallel to the longitudinal axis of the barrel) to a generally horizontal direction (i.e., perpendicular to the longitudinal axis of the barrel). change direction. As a result, airflow is emitted from outlet 213 in a generally circumferential direction. This encourages the airflow to wrap better around the barrel 210.

Dial 220 resembles a star wheel surrounding the bottom of inner sleeve 240. Dial 220 includes a slot 221 in which leg 251 of louver 250 is received. Dial 220 is rotatable relative to inner sleeve 250. More specifically, dial 220 is rotatable about the longitudinal axis of barrel 210. Rotating dial 220 clockwise and counterclockwise pivots each of louvers 250 between a first position and a second position. As a result, dial 220 can be used to change the direction in which airflow is emitted from barrel 210.

Knob 260 is attached to the top of inner sleeve 240 and is isolated from the airflow moving within barrel 210. Thus, knob 260 provides a relatively cool area of barrel 210 that a user can grasp when operating hair care device 10.

The attachments 100, 200 described above change the direction of airflow in different ways. However, what each has in common is the presence of a member (e.g., inner sleeve 140 in FIGS. 4-7 or louver 250 in FIGS. 9-11) that moves between a first position and a second position. be. Airflow is then emitted from the attachment in a clockwise direction when the member is in the first position, and airflow is emitted in a counterclockwise direction when the member is in the second position. Each of the attachments 100, 200 also includes a first outlet 113a, 213a from which the airflow is emitted in a clockwise direction, and a second outlet 113b, 213b from which the airflow is emitted in a counterclockwise direction. It can be said that it has. The member 140, 250 then blocks airflow to the second outlet 113b, 213b when in the first position and blocks airflow to the first outlet 113a, 213a when in the second position. occlude. For example, in the attachment 100 of FIGS. 4-7, the barrel 110 can be said to have a first outlet 113a and a second outlet 113b formed between the slat 160 and the outer sleeve 150. The airflow is emitted through the first outlet 113a in a clockwise direction (FIG. 7(a)) and through the second outlet 113b in a counterclockwise direction (FIG. 7(b)). The inner sleeve 150 (i.e., the member) is configured such that from a first position (FIG. 7(a)) where the sleeve 150 blocks the path of air flow to the second outlet 113b, the sleeve 150 blocks the air flow path to the first outlet 113a. It is movable to a second position (FIG. 7(b)) in which the flow path is occluded.

Figures 12-15 show further configurations for changing the direction of airflow. FIG. 12 shows a third configuration of attachment 300 in which barrel 310 includes four segments 320. Each segment 320 pivots about an axis 325 that is offset from the longitudinal axis of barrel 310. Each segment 320 pivots between a first position (FIG. 12(a)) and a second position (FIG. 12(b)). In the first position, a first edge of an outer wall 321 of a segment abuts an inner wall 322 of an adjacent segment, and a second edge of the outer wall 321 is spaced radially beyond the outer wall of another adjacent segment. are doing. Thus, a seal is formed on one side of each segment 320 and an outlet is formed on the other side. The four segments 320 pivot in unison, creating an outlet on the same side of each segment 320 at the same time. When the segment 320 is in the first position (FIG. 12(a)), airflow is emitted from the first outlet 313a in a clockwise direction. Then, when the segment is in the second position (FIG. 12(b)), the airflow is emitted from the second outlet 313b in a counterclockwise direction.

FIG. 13 shows a fourth configuration of the attachment 400 in which the barrel 410 comprises four pairs of blades 421, 422. Each pair of blades 421, 422 pivots about an axis 423 located midway between the two blades. Each first blade 421 of a pair is connected along its edge to the edge of a second blade 422 of an adjacent pair by a resilient element 430 . The four pairs of blades pivot in unison between a first position (FIG. 13(a)) and a second position (FIG. 13(b)). When in the first position, the first blade 421 of each pair is on the outside and the second blade 422 of each pair is on the inside. Conversely, when in the second position, the first blade 421 is on the inside and the second blade 422 is on the outside. As seen in Figure 13, each pair of blades 421, 422 moves in a counterclockwise direction when moving from a first position (Figure 13(a)) to a second position (Figure 13(b)). Pivot. When in the first position, the elastic element 430 is stretched and pulled around the outside of the first blade 421 of each blade pair. Airflow is then emitted from the first outlet 413a in a clockwise direction through the channels 424 between each pair of blades. When moved to the second position, the resilient member 430 is instead stretched around the outside of the second blade 422 of each pair of blades. Air is then released from the second outlet 413b through channel 424 in a counterclockwise direction.

FIG. 14 shows a fifth configuration of attachment 500 in which barrel 510 includes an inner sleeve 520, an outer sleeve 530, and a plurality of columns 540. Each column 540 pivots or rotates about its respective center between a first position (FIG. 14(a)) and a second position (FIG. 14(b)). Inner sleeve 520 and outer sleeve 530 define a pair of channels 551, 552. When in the first position, each column 540 opens the first channel 551 and closes the second channel 552 of the pair of channels. The airflow is then emitted in a clockwise direction through the first outlet 513a (FIG. 14(a)). When in the second position, each column 540 closes a first channel 551 and opens a second channel 552. The airflow is then emitted in a counterclockwise direction through the second outlet 513b (FIG. 14(b)). All five columns 540 are arranged to move in unison, and the airflow is emitted in a clockwise or counterclockwise direction over the outer surface of the barrel 510. By providing the inner sleeve 520, the airflow is encouraged to travel circumferentially before being discharged from the outlet. This improves the attraction of the exiting airflow to the surface of the barrel 510, ie, the Coanda effect. Nevertheless, it is also conceivable to omit the inner sleeve 520.

FIG. 15 shows a sixth configuration of the attachment 600 in which the barrel 610 includes a plurality of columns 620 and a plurality of moving elements 630. Each moving element 630 is positioned between a pair of columns 620. The moving elements 630 collectively rotate about the longitudinal axis of the barrel between a first position (FIG. 15(a)) and a second position (FIG. 15(b)). Each moving element 630 is narrower than the circumferential gap between adjacent columns. As a result, an outlet is created between each moving element 630 and column 620. More specifically, when the moving element 630 is in the first position (FIG. 15(a)), a first outlet 613a is created and airflow is emitted in a clockwise direction through the first outlet 613a. . When the moving element 630 is in the second position (FIG. 15(b)), a second outlet 613b is created and airflow is emitted in a counterclockwise direction through the second outlet 613b.

In the example described above, each attachment has a first configuration in which the airflow is emitted in a clockwise direction and a second configuration in which the airflow is emitted in a counterclockwise direction. Within each configuration, airflow is emitted from the outlet substantially tangentially to the outer surface of the barrel. As a result, the airflow emitted from the outlet is attracted to the outer surface by the Coanda effect. This has the advantage that the hair presented on the attachment is drawn to the barrel and wraps around it. In other examples, the attachment may have an additional configuration in which the airflow is emitted from the outlet in a direction other than tangential to the outer surface of the barrel. For example, the attachment may have a third configuration in which the airflow is emitted from the outlet in a direction substantially perpendicular to the outer surface of the barrel. This provides the user with a choice of diffuser types and may be useful, for example, once the hair is wrapped and the user wishes to dry the hair.

The attachments described above each include a dial to select clockwise or counterclockwise airflow. Providing a dial that rotates about the longitudinal axis of the attachment allows the user to change the direction of airflow in a relatively intuitive manner. In particular, the user can rotate the tire clockwise and counterclockwise to select clockwise and counterclockwise airflow, respectively. Notwithstanding the foregoing advantages, the hair care device may include alternative types of selectors that may be actuated by the user to select clockwise or counterclockwise airflow.

The dial or other user actuated selector may be latched and may have two stable positions corresponding to the first and second positions of the movable member. This has the advantage that the dial, and thus the movable member, are less likely to be moved accidentally during use of the hair care device. Additionally, the dial automatically latches into place when rotated, increasing the likelihood that the movable member will be in the correct position. Therefore, the user does not need to precisely position the dial during use.

By way of example, the dial 120 of the attachment 100 of FIGS. 4-7 may be locked when in a first position and when in a second position. To move dial 120 between the first and second positions, dial 120 may be depressed to release dial 120 from the locked position. When dial 120 is depressed, the dial may rotate between a first position and a second position. Once in position, the dial 120 may be released and the dial 120 may be automatically guided back to the locked position, for example by a biasing spring and guide arrangement.

FIG. 16 shows a further example in which the dial 220 of the attachment 200 of FIGS. 9-11 includes a latching mechanism 1000. Latch mechanism 1000 includes a spring 1004 that slides over a U-shaped clip 1002. A first pin 1006a is located on the dial 220. A first pin 1006a is sandwiched between the U-shaped end 1002a of the clip 1002 and one end of the spring 1004. Another pin 1006b is located on the barrel 210. The two unconnected ends 1002b of the U-shaped clip 1002 slot around pin 1006b and the other end of the spring are biased against pin 1006b.

As dial 220 rotates clockwise, pins 1006a, 1006b move closer together. The spring is held between two pins 1006a, 1006b by a clip 1002. The spring is therefore forced to contract. When the spring is in the contracted state, the latching mechanism is in an unstable state due to the potential energy stored in the compression spring 1004. The elastic potential energy stored in the compression spring 1004 forces the latching mechanism back to one of its stable positions, ie, the spring's most relaxed position. The first stable position of the latch mechanism 1000 is to the right of line YY. From the right up along line YY, the latch mechanism 1000 urges the louver 250 (ie, the movable member) back toward a first stable position corresponding to the first position of the louver 250. Towards the left beyond line YY, latch mechanism 1000 biases louver 250 toward a second stable position. In this manner, attachment 200 is more likely to be in the correct position during use, as the latching mechanism automatically snaps louvers 250 into place upon rotation of dial 220.

Each of the attachments is removably attached to the handle unit. This has the advantage that the handle unit can be used with other types of attachments, such as styling brushes or hair dryer nozzles. Nevertheless, it is also conceivable that the hair care device comprises an attachment permanently attached to the handle unit.

Each slat is configured to engage a first edge of each blade when the blade is in the first configuration and a second edge of each blade when the blade is in the second configuration. It may also include a sealing element configured to. This further suppresses fluid leakage from the gap between the edge of the blade and the column.

The sealing element may include a compressible material. This allows the sealing element to deform to accommodate the edge of the blade, improving the seal.

The invention is not limited to the above detailed description. Variations will be apparent to those skilled in the art.
