Description

Technical Field

[0001] This invention relates to a hair care tool and an accessory for the hair care tool. Background Technology

[0002] Hair styling tools are typically used to treat or style hair, and some tools use airflow to do so. To provide versatility for treating and styling hair, some tools offer airflow at variable speeds. Summary of the Invention

[0003] According to a first aspect of the invention, an accessory for a hair care device is provided, the accessory including an air inlet for receiving airflow from an airflow generator and an air outlet for discharging airflow, wherein the accessory includes a fixed body defining the air outlet and a rotatable member rotatable relative to the fixed body, wherein the air outlet includes a first hole located on a first side of the fixed body and a second hole located on a second side of the fixed body opposite to the first side of the fixed body, the rotatable member being rotatable from a first configuration to a second configuration, wherein in the first configuration the rotatable member allows airflow through the first hole and blocks airflow through the second hole, and in the second configuration the rotatable member allows airflow through the second hole and blocks airflow through the first hole, the rotatable member being located inside the fixed member.

[0004] The appendix according to the first aspect of the invention may be advantageous because the rotatable member can be rotated from a first configuration to a second configuration, in which the rotatable member allows airflow through a first hole and blocks airflow through a second hole, and in the second configuration, the rotatable member allows airflow through the second hole and blocks airflow through the first hole. Specifically, this can provide an arrangement in which airflow passes through the first hole but not the second hole in the first configuration, and airflow passes through the second hole but not the first hole in the second configuration. In use, this can allow for a larger volume of airflow on one side of the hair styling tool relative to the other side, which can provide increased efficiency, such as less wasted airflow away from the direction of the hair, and can provide increased styling control by directing the airflow primarily in the desired direction, thereby reducing the risk of stray airflow affecting the styling process.

[0005] Using rotatable components can provide a more reliable arrangement than, for example, linearly movable components, because rotatable components experience less friction during use, thus reducing the risk of failure.

[0006] Positioning the rotatable component inside the fixed component reduces the risk of external objects, such as hair, dust, or debris, being caught during the movement of the rotatable component, and this also reduces the risk of rotatable component failure.

[0007] The accessories and the hair care tools attached to them may include a central axis, such as a central longitudinal axis, and the first and second sides of the fixing body may be located on opposite sides of the central axis. The first and second sides of the fixing body may be located on opposite sides of a plane containing the central axis.

[0008] The first and second holes can be positioned relative to each other, for example, substantially diametrically opposite to each other on the fixed body.

[0009] The rotatable component may be located radially inside the fixed body. The fixed body may define a cavity therein in which the rotatable component is housed.

[0010] The rotatable member may include a channel, which in a first configuration may be at least partially aligned with a first aperture, and in a second configuration may be at least partially aligned with a second aperture. This allows airflow to pass through the rotatable member to reach the first and second apertures in the respective first and second configurations.

[0011] The rotatable member may include a blocking surface, in which the second hole can be blocked by the blocking surface in a first configuration, and in the second configuration, the first hole can be blocked by the blocking surface. This prevents airflow from passing through the rotatable member to reach the second and first holes in the respective first and second configurations.

[0012] The first side of the rotatable member may include a blocking surface, and the second side of the rotatable member may include a channel. This allows for the selective opening and closing of first and second holes on the respective first and second sides of the fixed body.

[0013] The blocking surface may include a perimeter, the length of which substantially corresponds to half the perimeter of the stationary body. The stationary body may be generally cylindrical, and the blocking surface may be generally semi-cylindrical. The blocking surface may include a circumferential range substantially corresponding to half the circumferential range of the stationary body. This ensures that half of the stationary body is blocked by the blocking surface at any given time, thereby ensuring that airflow can only pass through one side of the stationary body at any given time.

[0014] The blocking surface can be essentially solid, for example, uninterrupted, in which virtually no holes are formed.

[0015] In a first configuration, the channel can be at least 50% aligned with a first hole, and in a second configuration, the channel can be at least 50% aligned with a second hole. In a first configuration, the channel can be fully aligned with a first hole, and in a second configuration, the channel can be fully aligned with a second hole.

[0016] In the first configuration, the first side of the rotatable member can be aligned with the second side of the fixed body, and in the second configuration, the second side of the rotatable member can be aligned with the first side of the fixed body.

[0017] The rotatable component can rotate about a central axis. This provides a simpler arrangement compared to a rotatable component that, for example, can rotate about an axis off-center from the central axis.

[0018] The rotatable component can rotate about an axis that is off-center from the central axis. This provides greater flexibility in positioning the rotatable component relative to the fixed component.

[0019] Rotatable components can include monolithic structures, such as single integral parts. Compared to using multiple or more rotatable components, this can reduce the number of parts and cost, and can reduce the risk of failure during use.

[0020] In the first configuration, no airflow can pass through the second side of the fixed body, and in the second configuration, no airflow can pass through the first side of the fixed body. In use, this allows for a larger volume of airflow on one side of the hair styling tool relative to the other side, which can provide increased efficiency, such as less wasted airflow away from the direction of the hair, and increased styling control by directing the airflow primarily in the desired direction, thereby reducing the risk of stray airflow affecting the styling process.

[0021] The first and second holes can be shaped such that airflow passes through them in a radial direction. In use, this can provide greater directionality of airflow from the hair care device, for example, compared to an arrangement where airflow passes through the first and second holes in a direction tangential to the fixing body.

[0022] The first and second holes can be shaped such that airflow passes through them tangentially. This allows for airflow along the length of the hair during use, providing increased styling control and reducing scattering during use.

[0023] The accessory may include a user-actuable turntable for rotating the rotatable component relative to the fixed body. This provides a simple mechanism for moving the rotatable component relative to the fixed body and offers increased user control and ease of use compared to hair care appliances, for example, those with accessories that allow the rotatable component to rotate automatically without user input.

[0024] The rotatable component can rotate relative to the fixed body under the influence of gravity. This provides automatic movement of the rotatable component in response to different orientations of the hair care appliance and accessories, and eliminates the need for the user to interact with the hair care appliance during use to modify the direction of airflow away from the appliance.

[0025] The rotatable component may include a counterweight such that when the hair care tool and accessories are held parallel to the surface the user is standing on, airflow is directed through one of the first and second holes facing that surface. The counterweight provides a simple mechanism to ensure the movement of the rotatable component under gravity. The counterweight may be located near the channel. This ensures that the channel aligns with the corresponding hole during use. A second side of the rotatable component may also include the counterweight.

[0026] The accessory may include a signal generator for generating a signal indicating that hair is in contact with the accessory, and a drive mechanism for driving a rotatable member to move in response to the signal indicating that hair is in contact with the accessory. This ensures that the rotatable member is in the correct configuration so that airflow can be provided to the hair to be styled and / or dried during use. When the signal indicates that hair is in contact with a first side of the accessory corresponding to a first side of the fixing body, the drive mechanism can drive the rotatable member to move to a first configuration. When the signal indicates that hair is in contact with a second side of the accessory corresponding to a second side of the fixing body, the drive mechanism can drive the rotatable member to move to a second configuration.

[0027] The signal can indicate physical contact between the hair and the accessory, or it can indicate potential contact between the hair and the accessory. The signal generator can be configured to generate a signal when the hair is no more than 1 cm, no more than 0.5 cm, or no more than 0.25 cm away from the accessory.

[0028] The accessory may include multiple bristles for contacting the hair, and a signal generator may be configured to generate a signal when the hair contacts the multiple bristles. Providing multiple bristles increases the flexibility of hair styling while also ensuring that the signal generator has a bristle-like engagement mechanism for triggering signal generation.

[0029] The signal generator may include a sensor for detecting the presence of hair, and the signal generator may be configured to generate a signal based on the sensor's output. Using a sensor (e.g., a digital sensor) to generate the signal output, upon which the output (i.e., a trigger) is based, can provide a system with fewer moving parts, and is therefore less prone to failure than a signal generator, for example, one whose trigger is provided by a mechanical mechanism. The sensor may include a proximity sensor, which can allow a signal to be generated when the hair is within a predetermined threshold distance of the attachment. The sensor may include a capacitive sensor, such as a capacitive touch sensor.

[0030] The accessory may include a switch that, when engaged by hair, opens or closes the circuit, and the change in the circuit state can cause a signal to be generated. Using such a switch ensures that a signal is generated only when the circuit state changes.

[0031] The switch may include a pressable switch that is pressed when the accessory engages with the hair. Such a pressable switch provides a relatively simple, inexpensive, and reliable engagement mechanism.

[0032] The switch may include a pair of spaced-apart electrical contacts and a conductive member configured to selectively bridge the pair of contacts when the accessory comes into contact with hair. This type of switch may require less physical space than, for example, a push-button switch, which could allow for a reduction in the size of at least a portion of the accessory.

[0033] The signal generator may include an image sensor and / or a light sensor to detect the presence of hair, and generate a signal when the image sensor and / or light sensor detect the presence of hair in use.

[0034] The air outlet may include a plurality of holes spaced apart around the periphery of the accessory, such that the holes are located on a first side of the fixed body and a plurality of holes are located on a second side of the fixed body, and a rotatable member is rotatable such that, in a first configuration, the rotatable member allows airflow through the plurality of holes on the first side of the fixed body and blocks airflow through the plurality of holes on the second side of the fixed body, and in a second configuration, the rotatable member allows airflow through the plurality of holes on the second side of the fixed body and blocks airflow through the plurality of holes on the first side of the fixed body. This can provide a more diffused airflow than, for example, a single large hole on either side of the accessory, which can increase user comfort.

[0035] The second side of the rotatable member may include multiple channels, each aligned with at least one hole in the first and second configurations. A blocking surface may block the multiple holes in the first and second configurations.

[0036] Hair care appliances may include a handle unit and an accessory. The handle unit contains an airflow generator, and the accessory includes an air outlet, which is detachably attached to the handle unit. Providing the aforementioned air outlet as part of a detachable accessory allows the user to selectively access the functions described herein.

[0037] According to another aspect of the present invention, a hair care appliance is provided, comprising an air inlet, an air outlet, an airflow generator for generating airflow from the air inlet to the air outlet, a fixed body defining the air outlet, and a rotatable member rotatable relative to the fixed body, wherein the air outlet includes a first hole located on a first side of the fixed body and a second hole located on a second side of the fixed body opposite to the first side of the fixed body, the rotatable member being rotatable from a first configuration to a second configuration, wherein in the first configuration the rotatable member allows airflow through the first hole and blocks airflow through the second hole, and in the second configuration the rotatable member allows airflow through the second hole and blocks airflow through the first hole, the rotatable member being located inside the fixed body.

[0038] According to a third aspect of the invention, a hair care appliance is provided, comprising an air inlet, an air outlet, an airflow generator for generating airflow from the air inlet to the air outlet, a fixed body defining the air outlet, and a rotatable member rotatable relative to the fixed body, wherein the air outlet includes a first hole located on a first side of the fixed body and a second hole located on a second side of the fixed body opposite to the first side of the fixed body, the rotatable member being rotatable from a first configuration to a second configuration, wherein in the first configuration the rotatable member allows airflow through the first hole and blocks airflow through the second hole, and in the second configuration the rotatable member allows airflow through the second hole and blocks airflow through the first hole, and the rotatable member is rotatable relative to the fixed member under the influence of gravity during use.

[0039] The hair care appliance according to a third aspect of the invention may be advantageous because the rotatable member can be rotated from a first configuration to a second configuration, in which the rotatable member allows airflow through a first hole and blocks airflow through a second hole, and in the second configuration, the rotatable member allows airflow through the second hole and blocks airflow through the first hole. Specifically, this can provide an arrangement in which airflow passes through the first hole but not the second hole in the first configuration, and airflow passes through the second hole but not the first hole in the second configuration. This allows for a larger volume of airflow to be provided on one side of the hair care appliance relative to the other side during use, which can provide increased efficiency, such as less wasted airflow away from the direction of the hair during use, and can provide increased styling control by directing the airflow primarily in the desired direction during use, thereby reducing the risk of stray airflow affecting the styling process.

[0040] Using rotatable components can provide a more reliable arrangement than, for example, linearly movable components, because rotatable components experience less friction during use, thus reducing the risk of failure.

[0041] By rotating the rotatable component relative to the fixed component under the influence of gravity during use, the switching between the first and second configurations can be achieved automatically, thereby reducing the need for user input and providing increased user convenience.

[0042] The rotatable component may include a counterweight such that when the hair care device is held parallel to the surface the user is standing on, airflow is directed through one of the first and second holes facing that surface. The counterweight can provide a simple mechanism to ensure the movement of the rotatable component under gravity.

[0043] The rotatable member may include a channel, which in a first configuration may be at least partially aligned with a first aperture, and in a second configuration may be at least partially aligned with a second aperture. This allows airflow to pass through the rotatable member to reach the first and second apertures in the respective first and second configurations. The channel may include a first channel portion and a second channel portion, in the first configuration where the first channel portion is at least partially aligned with the first aperture and the second channel portion is not aligned with the second aperture, and in the second configuration where the first channel portion is not aligned with the first aperture and the second channel portion is at least partially aligned with the second aperture.

[0044] The rotatable member may include a blocking surface, in which the second hole can be blocked by the blocking surface in a first configuration, and in the second configuration, the first hole can be blocked by the blocking surface. This prevents airflow from passing through the rotatable member to reach the second and first holes in the respective first and second configurations.

[0045] The rotatable component can be located inside the fixed component, for example, radially inside the fixed component within a hollow interior. This reduces the risk of external objects such as hair, dust, or debris being trapped during the movement of the rotatable component, and it also reduces the risk of failure of the rotatable component.

[0046] The rotatable component can be located outside the fixed component, for example, radially outward from the hollow interior of the fixed component. This allows the movable component to be removed from the flow path inside the fixed component, which can result in a larger cross-sectional area for the flow path and reduce turbulence inside the fixed component during use.

[0047] Hair care devices may include a central axis, such as a central longitudinal axis, and the first and second sides of the fixing body may be located on opposite sides of the central axis. The first and second sides of the fixing body may be located on opposite sides of a plane containing the central axis.

[0048] The first and second holes can be positioned relative to each other, for example, substantially diametrically opposite to each other on the fixed body.

[0049] Rotatable components can include monolithic structures, such as single integral parts. Compared to using multiple or more rotatable components, this can reduce the number of parts and cost, and can reduce the risk of failure during use.

[0050] In the first configuration, no airflow can pass through the second side of the fixed body, and in the second configuration, no airflow can pass through the first side of the fixed body. This allows for a larger volume of airflow on one side of the hair styling tool relative to the other side during use. This provides increased efficiency, such as less wasted airflow away from the direction of the hair during use, and provides increased styling control by directing the airflow primarily in the desired direction during use, thereby reducing the risk of stray airflow affecting the styling process.

[0051] Hair care appliances may include a handle unit and an accessory. The handle unit contains an airflow generator, and the accessory includes an air outlet, which is detachably attached to the handle unit. Providing the aforementioned air outlet as part of the detachable accessory allows the user to selectively access the functions described herein.

[0052] According to a fourth aspect of the invention, an accessory for a hair care device is provided, the accessory comprising an air inlet for receiving airflow and an air outlet for discharging airflow, wherein the accessory comprises a fixed body defining the air outlet and a rotatable member rotatable relative to the fixed body, wherein the air outlet comprises a first hole located on a first side of the fixed body and a second hole located on a second side of the fixed body opposite to the first side of the fixed body, the rotatable member being rotatable from a first configuration to a second configuration, wherein in the first configuration the rotatable member allows airflow through the first hole and blocks airflow through the second hole, and in the second configuration the rotatable member allows airflow through the second hole and blocks airflow through the first hole, and the rotatable member is rotatable relative to the fixed member under the influence of gravity during use.

[0063] exist Figure 1 The image schematically illustrates a hair care device according to the invention, typically designated 10.

[0064] The hair care device 10 includes a handle unit 12 and an accessory 100 removably attached to the handle unit 12.

[0065] like Figure 2 As schematically shown, the handle unit 12 includes a housing 14, an airflow generator 16, a heater 18, and a control unit 20.

[0066] The housing 14 is tubular and includes an air inlet 22 and an air outlet 24. Airflow is drawn into the housing 14 through the air inlet 22 by the airflow generator 16 and exits the housing 14 through the air outlet 24. The airflow generator 16 is housed within the housing 14 and includes an impeller 26 driven by an electric motor 28. A heater 18 is also housed within the housing 14 and includes a heating element 30 to optionally heat the airflow.

[0067] The control unit 20 includes electronic circuitry for a user interface 32 and a control module 34. The user interface 32 is located on the outer surface of the housing 14 and is used to turn the hair care appliance 10 on and off, select the flow rate (e.g., high, medium, and low), and select the airflow temperature (e.g., hot, medium, or cold). Figure 1 In the example, the user interface includes multiple sliding switches, but other forms of user interface 32 can also be envisioned, such as buttons, dials, or touch screens.

[0068] The control module 34 is responsible for controlling the airflow generator 16 and the heater 18 in response to input from the user interface 32. For example, in response to input from the user interface 32, the control module 34 can control the power or speed of the airflow generator 16 to regulate the airflow velocity, and control the power of the heater 18 to regulate the airflow temperature.

[0069] Annex 100 Figure 3 and 4 It is shown schematically in the diagram.

[0070] Annex 100 Figures 3 to 6 The diagram is shown schematically. Attachment 100 includes a fixed body 102 and a rotatable member 104 that is rotatable relative to the fixed body 102.

[0071] The fixing body 102 is typically cylindrical, open at one end and closed at the other. The open end serves as an inlet 106 for the fixing body 102. The fixing body 102 is typically hollow and has a recess within which the rotatable member 104 can rotate, as will be described below. The outer surface of the fixing body 102 includes an opening 108 through which bristles 110 extend and a plurality of holes 112 serving as air outlets for the attachment 100. The holes 112 and openings 108 are arranged in columns around the periphery of the outer surface of the attachment 100, with the openings 108 and holes 112 alternating in each column. The openings 108 and holes 112 are offset between adjacent columns such that an opening 108 in one column is substantially aligned with a hole 112 in an adjacent column in the same row.

[0072] The rotatable member 104 is a monolithic, single-piece structure, typically hollow, having a first side 114 and a second side 116. The first side 114 of the rotatable member 104 is substantially solid, such that it defines a blocking surface 115. The second side 116 of the rotatable member 104 includes a plurality of channels 118 through which airflow can pass during use.

[0073] The connecting portion 120 of the second side 116 of the rotatable member 104 extends radially inward toward the center of the rotatable member 104, and the rod 122 extends through the connecting portion 120 and is located within the recess of the fixed body 102, allowing the rotatable member 104 to rotate within the fixed body 102 during use. A counterweight 124 is embedded in the connecting portion 120 such that the counterweight 124 is located within the second side 116 of the rotatable member 104. This ensures that when the accessory 100 is held horizontally by the user, the second side 116 of the rotatable member 104, and therefore the channel 118, faces downward, for example, allowing airflow to be guided through the channel 118 in a generally downward direction.

[0074] from Figure 4It can be seen that the fixing body 102 can also be considered to have a first side 126 and a second side 128, which are located on both sides of the central longitudinal axis C of the attachment 100, and a hole is provided on each side of the first side 126 and the second side 128 of the fixing body 128. Figure 4 In the configuration shown, the first side 126 faces generally downwards, while the second side 128 faces generally upwards. Here, the second side 116 of the rotatable member 104 is aligned with the first side 126 of the fixed body 102, and the first side 114 of the rotatable member 104 is aligned with the second side 128 of the fixed body 102. Therefore, in Figure 4 In the configuration shown, the channel 118 of the rotatable member 104 is aligned with the hole 112 on the first side 126 of the fixed body 102, while Figure 4 In the configuration shown, the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102.

[0075] In this way, airflow can escape from the hole 112 on the first side 126 of the fixing body 102, while preventing airflow from escaping from the hole 112 on the second side 128 of the fixing body 102. This allows for a larger volume of airflow on one side of the attachment 100 relative to the other side of the attachment 100 during use, which can provide increased efficiency, such as less wasted airflow away from the direction of the hair during use, and can provide increased styling control by directing the airflow primarily in the desired direction during use, thereby reducing the risk of stray airflow affecting the styling process.

[0076] As previously described, the rotatable member 104 is rotatable relative to the fixed body 102, and the second side 116 of the rotatable member 104 includes a counterweight 124. If the user wants to rotate the hair care appliance 10, i.e., rotate the hair care appliance about the central longitudinal axis C, then, given the rotatable member 104 and its weight 124, the rotatable member will remain stationary. Figure 4 At the position shown, the first side 126 and the second side 128 of the fixed body 102 will be flipped. Figure 5 This configuration is shown in the image.

[0077] exist Figure 5 In this configuration, the first side 126 of the fixed body 102 faces generally upward, while the second side 128 of the fixed body 102 faces generally downward. Here, the second side 116 of the rotatable member 104 is aligned with the second side 128 of the fixed body 102, while the first side 114 of the rotatable member 104 is aligned with the first side 126 of the fixed body 102. Therefore, in Figure 5 In the configuration shown, the channel 118 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102, while Figure 4 In the configuration shown, the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the first side 126 of the fixed body 102.

[0078] In this way, airflow can escape from the hole 112 on the first side 126 of the fixing body 102, while preventing airflow from escaping from the hole 112 on the second side 128 of the fixing body 102. Therefore, airflow always passes through only one side of the accessory 100.

[0079] Figure 6 It shows the relationship with Figure 1 Another embodiment of the accessory 200 used together with the main body 12 of the hair care tool 10. Except that the counterweight 124 of the rotatable member 104 has been removed, Figure 6 Annex 200 is basically similar to Figures 3 to 5 Annex 100, and in place of, Figure 6 The accessory 300 includes a user-actuable turntable 202 protruding upward from the accessory. The user-actuable turntable 202 is mechanically connected to the rotatable member 104 in any suitable manner, such that rotation of the user-actuable turntable 302 causes rotation of the rotatable member 104 within the fixed body in a manner similar to... Figure 4 and 5 The configuration shown.

[0080] For example, the user-actuable turntable 202 can be used to move the rotatable member from a first configuration to a second configuration. In the first configuration, the channel 118 of the rotatable member 104 is aligned with the hole 112 on the first side 126 of the fixed body 102, while the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102. In the second configuration, the channel 118 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102, while the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the first side 126 of the fixed body 102. Therefore, airflow can be provided only through one side of the accessory 200 at a time, with the side allowing airflow selected by the user via the user-actuable turntable 202.

[0081] Figure 7 It shows the relationship with Figure 1 Another embodiment of the accessory 300 used together with the main body 12 of the hair care tool 10. Except that the counterweight 124 of the rotatable member 104 has been removed. Figure 7 Annex 300 is basically similar to Figures 3 to 5 Instead of Annex 100, there is... Figure 7The accessory 300 includes a signal generator 302 to generate a signal indicating that the hair is in contact with the accessory 300, and a drive motor 304 to drive the rotation of the rotatable member 104 in response to the signal provided by the signal generator 302.

[0082] The signal generator 302 can take any suitable form, including, for example, any of a proximity sensor, a capacitive sensor, a switch that opens or closes the circuit when a hair is engaged, an image sensor, and a light sensor.

[0083] In response to a signal generated by signal generator 302, drive motor 304 can drive the rotation of rotatable member 104 so that airflow is always directed towards the hair during use. For example, drive motor 304 can drive the rotation of rotatable member 104 within a fixed body to employ a similar... Figure 4 and 5 The configurations shown, although in Figure 7 Rotate 90 degrees. Given the different mechanisms used to move the rotatable component 104, it will be understood that... Figure 7 In this embodiment, the air passage 112 can be located in any rotational direction around the periphery of the attachment 300, and not just like... Figure 4 and 5 As shown in the embodiment, it is positioned in the downward direction.

[0084] For example, a signal generator 302 and a drive motor 304 can be used to move the rotatable member 104 from a first configuration to a second configuration, in which the channel 118 of the rotatable member 104 is aligned with a hole 112 on the first side 126 of the fixed body 102. Figure 7 (Left side of the central axis), while the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102. Figure 7 In the second configuration (on the right side of the central axis), the channel 118 of the rotatable member 104 is aligned with the hole 112 on the second side 128 of the fixed body 102, while the blocking surface 115 of the rotatable member 104 is aligned with the hole 112 on the first side 126 of the fixed body 102. Therefore, airflow can be provided only through one side of the accessory 300 at a time, and the side through which airflow is allowed is selected and determined by the signal generator 302 and the drive motor 304.

[0085] Figure 8 and 9 It shows the relationship with Figure 1 Another embodiment of the accessory 400 used together with the main body 12 of the hair care tool 10.

[0086] Figure 8The accessory 400 includes a fixed body 402 having a first hole 404 and a second hole 406, and a rotatable member 408 rotatable relative to the fixed body 402, such as... Figures 3 to 5 In this embodiment, rotation is achieved via a rod (not shown). Here, a rotatable member 408 is disposed radially outward of the fixed body 402, allowing the rotatable member 402 to rotate about an outward-facing surface of the fixed body 402. The rotatable member 408 has a single channel 410 formed therein, and a plurality of counterweights 412 embedded in the rotatable member 408 on either side of the channel 410. A plurality of bristles 414 extend outwardly from the rotatable member 408.

[0087] The first hole 404 is located on the first side 416 of the fixing body 402, and the second hole 406 is located on the second side 418 of the fixing body 402 opposite to the first side 416. The channel 410 is located on the first side 420 of the rotatable member 408, while the second side 422 of the rotatable member 408 is substantially solid, with no holes or openings formed therein except for holes or openings through which the bristles can extend.

[0088] Similar to Figures 3 to 5 Implementation examples, Figure 8 and 9 Annex 400 has such Figure 8 In the first configuration shown, the first side 420 of the rotatable member 408 is aligned with the first side 416 of the fixed body 402, such that the channel 410 is aligned with the first hole 404, and airflow can escape from the first side 416 of the fixed body 402. In the first configuration, airflow through the second hole 406 is blocked by the rotatable member 408.

[0089] Figure 8 and 9 Annex 400 has a second configuration, such as Figure 9 As shown, the first side 420 of the rotatable member 408 is aligned with the second side 418 of the fixed body 402, such that the channel 410 is aligned with the second hole 406, and airflow can escape from the second side 418 of the fixed body 402. In the second configuration, the airflow through the first hole 404 is blocked by the rotatable member 408.

[0090] These two configurations are achieved through multiple counterweights 412 embedded in the rotatable member 408, ensuring that airflow passes uniformly through only one side of the accessory 400. The multiple counterweights 412 allow the rotatable member 404 to rotate relative to the fixed body 402 under gravity during use, which provides automatic adjustment of airflow from different sides of the fixed body 402.

[0091] Although described as having only a first hole 404 and a second hole 406 and a single channel 410, it should be understood that multiple holes and channels can actually be provided, similar to Figures 3 to 5 An embodiment of Annex 100 shown.

[0092] Furthermore, despite Figure 8 and 9 Annex 400 is shown as a rotatable member 408 rotating about a central axis; however, it should be understood that embodiments in which the rotatable member 408 rotates within a fixed body about an axis offset from the central axis are also conceivable.

[0093] Some embodiments are also envisioned in which the hair care appliance 10 does not include a handle unit 12 and accessories 100, 200, 300, 400, but is a single unit, for example, in the form of a combined handle unit 12 and accessories 100, 200, 300, 400 as described above.
