[0017] In order that the present invention may be more readily understood, an embodiment thereof will now be described with reference to the accompanying drawings, in which: An example will be given.

[0018] Referring to the drawings, the hair styling device 10 has a reciprocating motion that moves toward and away from each other. The illustrated example includes a first arm 12 and a second arm 14 connected to each other for In the figure, the first arm 12 and the second arm 14 are held together by their respective hinges 17. The first arm 12 and the second arm 13 are pivotally mounted to a base in the form of a shoulder 16. The arm 14 is biased toward the open position by a spring (not shown), as shown in FIG. , which can be manually closed by the user against the bias of the spring.

[0019] Each of the first arm 12 and the second arm 14 is attached to a distal tip region 11 of the handle portion 16. Each of the first arm 12 and the second arm 14 has a tip end portion, in a plane, a tapered portion narrowing along the length of the first arm 12 and the second arm 14 toward the region 18 Includes 24 minutes.

[0020] The first arm 12 and the second arm 14 receive hair in an area in the form of a drying cavity 20. The drying cavity 20 is arranged to receive hair, as will be described in more detail below. A first arm 12 through which a hair strand 22 is captured when the styling device 10 is in use. and the second arm 14.

[0021] Each of the first arm 12 and the second arm 14 includes a leading edge 15 that, in use, guides hair. While being pulled through the hair styling device 10, the hair passes the leading edge 15 and dries. The first arm 12 and the second arm 14 each have a trailing edge 19. In use, while hair is being pulled through the hair styling device 10, passes the trailing edge 19 and leaves the dry cavity 20.

[0022] The portion of the handle portion 16 distal to the tip region 18 is generally hollow and is adapted for use with hair styling tools. It includes several exterior holes 26 through which air passes when the device 10 is in use. 28 filters the incoming air to prevent it from damaging downstream components or the user's hair. Removes dust and other particles that may be harmful.

[0023] After passing through the filter 28, the air passes through an impeller 30 driven by an electric motor 32. The motor 32 is powered by the mains power (supplied via a cable, depending on the implementation). The device may be powered by a power supply (not shown) and / or a battery (not shown).

[0024] Downstream of the motor 32, the air passes through a bellows 34. The bellows 34 is bifurcated. , the air is divided into a first duct 36 and a second duct 38. Each of the ducts 38 includes an offset in the form of an S-shaped portion 37 as shown in FIG. Alternatively, an offset such as an S-shaped section may be provided upstream of where the bellows diverges. In yet another alternative, a similar location where only a single plenum is provided may be used. An offset such as an S-shaped section may be provided in the airflow path of the device, thus No forks or, at least in some cases, bellows are required.

[0025] The first duct 36 is connected to a first planar air outlet in the first arm 12 via a first air inlet 42. The second duct 38 supplies air to the second arm 40 via a second air inlet 46. The bellows 34 supplies air to a second plenum 44 within the bellows 34. The bellows 34 is at least partially elastic. When the hair styling device is in the open position shown in FIG. This allows the first duct and the second duct to bend away from each other.

[0026] The first plenum 40 has an outlet in the form of a first slot 48 that opens into the dry cavity 20. Similarly, the second plenum 44 is in the form of a second slot 50 that opens into the dry cavity 20. The first slot 48 and the second slot 50 have respective first apertures. The first slot 48 and the second slot 49 extend along the inner surface of the arm 12 and the second arm 14. The slot 50 may take the form of a continuous opening in the hair styling device 10, but may alternatively be a form of one or more discontinuous and / or differently shaped openings disposed along the drying cavity 20; You can also take.

[0027] The first slot 48 and the second slot 50 are located closer to each other than the respective leading edges 15. is located near the trailing edge 19 of the

[0028] Each of the first plenum 40 and the second plenum 44 is configured to direct airflow through a respective first slot. longitudinally for heating the airflow before it is discharged from the first slot 48 and the second slot 50. The heater 66 includes an extending heater 66, which is described in more detail below with reference to Figures 13-15. explain.

[0029] As best shown in FIG. 12, each of the first plenum 40 and the second plenum 44 includes: tapering in a planar manner from where the corresponding ducts 36 / 38 join to the tip region 18 This reduction in the cross-sectional area of ​​the first plenum 40 and the second plenum 44 The S-shaped portion 37 compensates for the gradual decrease in air pressure with increasing distance from the rotor 32. The airflow is directed to a region of each plenum at a point distal from the slot 48 and the second slot 50. This allows for uniform pressure distribution over the length of the first plenum 40 and the second plenum 44. It helps to do so.

[0030] The sloped walls 51 within each plenum extend along most of the length of the plenum. The angle of the angled wall 51 relative to the slot 48 or slot 50 is such that the air flows from the plenum to the slot. 48 or 50. In the embodiment of FIGS. 1-6, the angle is approximately 6-10 degrees, more specifically approximately 8-9 degrees, and most specifically approximately Generally, an angle of 8.7 degrees has been found to be effective.

[0031] The first arm 12 includes a first air deflector 52 and the second arm 14 includes a second air deflector 54. The first air deflector 52 and the second air deflector 54 each include a first are disposed along the first arm 12 and the second arm 14, as will be described in more detail below. , so as to deflect at least a portion of the air flow away from the hair in the drying cavity 20. The first air deflector 52 and the second air deflector 54 are configured to deflect the air at their respective trailing edges. 19 is located closer to the leading edge 15 than the leading edge 19.

[0032] In the hair styling device 10, the first air deflector 52 partially deflects the first duct 56. The first duct 56 is also defined by a second air deflector 52 disposed on the opposite side of the first air deflector 52. The second air deflector 12 is partially defined by the first outer surface 58 of the arm 12. The air deflector 54 defines a second duct 60. The second duct 60 also defines a second air deflector. 54 is defined in part by a second outer surface 62 of the second arm 14 located opposite the do.

[0033] The first outer surface 58 and the second outer surface 62 are spaced apart from the dry cavity 20 in a cross section. The airflow 59 passing through the first duct 56 and the second duct 60 is smoothly curved. In addition to providing a suitable path for the airflow, the curvature of the first and second outer surfaces 58, 62 also facilitates proper flow of air. The airflow is directed towards the duct and is therefore restricted. The limit is reduced.

[0034] As best shown in FIGS. 3 and 6, the first duct 56 and the second duct 60 are The hairs are curved away from the drying cavity 20 along at least a portion of their length. In the styling device 10, the first duct 56 and the second duct 60 are 3 and 6, the airflow 59 is deflected from the hair in the drying cavity 20. This encourages people to move away from

[0035] The first duct 56 and the second duct 60 converge in a downstream direction in cross section. This causes the airflow 59 to accelerate as it leaves the first duct 56 and the second duct 60. This helps entrain the air, which in turn acts to lower the average temperature of the moving air. As the air temperature drops, it may become more This provides a better user experience.

[0036] The first duct 56 and the second duct 60 have their outer surfaces 58 and 62 and air deflection The air deflector 52 includes a plurality of vanes 64 disposed between the air deflector 52 and the air deflector 54. Each vane 64 includes a In use, the airflow exiting the first duct 56 and the second duct 60 is generally directed toward the hairstylist. The first arm 12 and the second arm 13 are biased toward the distal end region 18 of the ring device 10. The arm 14 is curved at an angle to the longitudinal axis of the arm 14. By orienting the hair styling device 10 in this way, the user's comfort can be improved depending on the orientation in which the hair styling device 10 is used. Specifically, the heated airflow may be directed away from the user's neck, head, or shoulders. This improves user comfort as the device is oriented in a more inviting direction.

[0037] In use, while the hair styling device 10 is in the open position shown in FIG. 5, the user presses the first A hair tuft 22 is placed in a drying cavity 20 between the arm 12 and the second arm 14. Typically, The hair styling device 10 is positioned with the trailing edge 19 close to the user's scalp. Other positions may be selected depending on the desired styling effect. First arm 12 and second arm 14 are squeezed together toward the closed position shown in FIG. Thus, the hair tufts 22 are trapped within the drying cavity 20 .

[0038] When driven by a motor 32, the impeller 30 forces air through the holes 26 and the filter 28. It draws in air and then forces it downstream through bellows 34, where it The airflow is divided between a first duct 36 and a second duct 38. The airflow is divided between the first duct 36 and the second duct 38. into a first plenum 40 and into a second plenum 44 through a second duct 38 .

[0039] The airflow passes through the first plenum 40 and the second plenum 44 to the respective heaters 6. The airflow is heated by heater 66 and then directed toward the first slot 68. The air exits the first plenum 40 and the second slot 50 and enters the dry cavity 20. The cross section of the plenum 44 of the second duct, as well as the S-shaped section 37, is tapered. The heated airflow passes from the first slot 48 and the second slot 50 to the first slot 4 8 and second slot 50 approximately evenly along the length thereof.

[0040] While the user pulls the hair styling device 10 away from the scalp, the heated airflow continues to dry the hair. The hair strands 22 within the cavity 20 are heated, dried, straightened, and smoothed. As the airflow leaves the tuft 22, most of it passes into the first duct 56 and the second duct 58. A small amount of air is directed through the gap between the inner edges of the first air deflector 52 and the second air deflector 54. The airflow passes through the first duct 56 and the second duct 57. 60 and directed away from the hair bundle 22, as explained in more detail above. The water is discharged at an angle.

[0041] The hair styling device 10 includes a first air intake duct having a plenum, an outlet, and an air deflector. Although both first arm 12 and second arm 14 are shown, other combinations of these configurations may be used. good.

[0042] In one embodiment, only one of the first arm 12 and the second arm 14 includes a plenum; Only one of the first arm 12 and the second arm 14 includes an air deflector. The arm with the air deflector need not be the same arm with the air deflector.

[0043] For example, FIG. 7 shows a cross section of a hair styling device 70, and The same reference numerals are used for the components common to the hair styling device 70. The first arm 14 does not include a plenum, and the first arm 12 does not include an air deflector. Therefore, all airflow leaving the drying cavity 20 passes through the duct 60.

[0044] FIG. 8 shows a cross section of a hair styling device 80, which is a cross section of the hair styling device 10 and the hair styling device 80. The same reference numerals are used for components common to the hair styling device 60. In vessel 80, second arm 14 includes plenum 44 and duct 60, while first arm 1 2 does not include a plenum or air deflector. Similar to the hair styling device 60, the drying cavity 2 All airflow exiting port 0 passes through duct 60, but in this case the airflow passes through second slot 50. into the drying cavity 20 via

[0045] In another embodiment, both the first arm 12 and the second arm 14 include plenums, but Only one of the first arm 12 and the second arm 14 includes an air deflector.

[0046] For example, FIG. 9 shows a cross section of a hair styling device 90, and 0, hair styling device 70, and hair styling device 80 are designated by the same reference numerals. In the hair styling device 90, the first arm 12 and the second arm 14 includes respective first and second plenums 40 and 44. 4 includes an air deflector 54, but the first arm 12 does not include an air deflector. All airflow leaving the drying cavity passes through the second duct 60 .

[0047] In another embodiment, only one of the first arm 12 and the second arm 14 includes a plenum. However, both the first arm 12 and the second arm 14 include air deflectors.

[0048] For example, FIG. 10 shows a cross section of a hair styling device 100. 10, hair styling device 70, hair styling device 80, and hair styling The same reference numerals are used for components common to the device 90. In the hair styling device 100, The first arm 12 includes a first plenum 40, while the second arm 14 does not include a plenum. Therefore, the airflow from the drying cavity 20 is directed to the hair styling device 10 of FIGS. The air passes through the first duct 56 and the second duct 60 in a manner similar to that described above, but In this case, airflow is supplied to the dry cavity 20 only through the first slot 48 .

[0049] Specific combinations of first and second arms, plenums, outlets, and air deflectors Although the above description is given with respect to a single component, any other combination of such components may be used depending on the desired implementation. It will be understood that by selecting a particular combination of these elements, Manufacturers can balance desired performance with manufacturing costs.

[0050] Additionally, although the use of a single motor 32 and impeller 30 has been described, a motor within each arm or It will be appreciated that a separate motor may be provided for each arm.

[0051] Additionally, all of the above-described hair styling devices use a base (such as the handle portion 16). However, those skilled in the art will appreciate that the arms may be directly connected to each other rather than through such a base. It will be understood that the motor 32 and impeller 30 may be mounted on one of the arms. or a separate motor and impeller may be mounted within each arm. It is possible.

[0052] First arm 12 and second arm 14 are generally symmetrical, but those skilled in the art will appreciate that It will be appreciated that this need not necessarily be the case. For example, one of the arms may be more flexible than the other. The volume may be large and may include, for example, the motor 32, the impeller 30, and the plenum, while The arm may not include these items. Air deflectors are used in this approach. It can be attached to either one.

[0053] Although the air deflectors described above take the form of linear elements defining longitudinal ducts, other embodiments are possible. In some embodiments, different forms of air deflectors may be used. For example, the air deflector may be a This may take the form of one or more openings formed through either or both. In this case, the air deflector is located at each opening where the air exiting the drying cavity 20 impinges and is redirected. Alternatively, the air deflector may be spaced apart from either or both of the arms. This may take the form of one or more longitudinal slats spaced apart.

[0054] The heater 66 may take any suitable form. Both plenums 40 and 44 contain heaters, but to avoid duplication, only the one in first plenum 40 is shown. Those skilled in the art will appreciate that in other implementations, only one of the plenums has a heater. It will be understood that if both plenums have heaters, they will be the same It doesn't have to be.

[0055] In the illustrated embodiment, as best seen in FIGS. 13-15, the heater 66 is mounted on a frame 7 The frame 71 comprises first frame elements 7 spaced apart in a direction generally perpendicular to the air flow. The frame elements 72 and 74 are a pair of frame elements 72 and 74. extend in a direction generally perpendicular to the flow and are generally, but not necessarily, parallel to one another The frame elements may be formed from mica, but any other suitable heat-resistant material. may be used.

[0056] Frame elements 72 and 74 are held apart by spacers 68. In this case, each spacer is cylindrical and made of mica, but may be made of any other material. Any suitable heat-resistant material may be used. Other materials may be used depending on the requirements of any particular implementation. The spacer 68 may have a cross-sectional shape of the frame element 72 and the frame element 73. 4 extending between the mutually opposing surfaces of the

[0057] In the illustrated embodiment, the air gaps are spaced apart in a direction parallel to the air flow by additional spacers 102. There is a second set of frame elements 172 and 174. The set of frame elements 172 and frame elements 174 is the first frame element 72 and the second frame element 74. 1. The set of elements 74 are spaced apart in an upstream direction.

[0058] As best shown in Figures 12 and 13, the spacer 68 and the additional spacer 102 are The offset 104 allows the flow direction to be , such that the spacer 68 and the further spacer 102 are directly aligned. The air disturbed by the spacer 102 is further disturbed by the downstream spacer 68. This results in a more uniform distribution of air and heat to the dry cavity 20.

[0059] Heaters used with hair styling appliances may include one or more heating elements. In the illustrated embodiment, a pair of frame elements 72 and 74 and a further frame The pair of frame elements 172 and 174 each have a heating element 96 extending over the heating area. The heating element 96 is wound around it so that it extends repeatedly. Body 96 takes the form of nichrome wire, although other types of materials and heating elements may be used. stomach.

[0060] In the illustrated implementation, the heating zones are repeated from frame element 172 to frame element 174. A first upstream heating region 98 defined by the repeatedly passing heating element 66 and a frame element The heating element 66 passes repeatedly from the element 174 to the frame element 172. 1. In this way, the frame element 172 and the frame element 17 4, the heating element 66 heats the hair styling device 10. Tightly cover areas where air flows during use.

[0061] In other implementations, the heating element is located in the space between frame element 172 and frame element 174. and a clamp, screw or any other suitable retaining means that can extend repeatedly over the entire Alternatively or additionally, the heating element may be held in place using a frame. It can be held in place by notches or holes in element 172 and frame element 174. The tension in the heating element optionally helps to hold the heating element in place.

[0062] The heating element may take any other suitable form, including resistive tape, traces, wires, etc. Optionally, the sheet may be corrugated, caster-finished, or otherwise molded to cover an increased area and improve heat transfer. This may include rations, undulations, fins, etc.

[0063] The frame elements 72 and 74 are similarly connected to the frame elements 172 and 174. In a similar manner as described for element 174, the a further upstream heating region 106 and a further downstream heating region 107 defined by a heating element passing through the element; The heating region includes a side region 108 .

[0065] The hair styling devices of Figures 16 to 19 each include a plurality of elements that are movable relative to one another. The plurality of elements includes a first arm 12 and a second arm 14.

[0066] In FIG. 16, the first arm 12 and the second arm 14 are arranged to pivot about a hinge 17. The first arm 12 and the second arm 14 are attached by a hinge 17. Further features related to the mechanism for allowing the hinges to pivot relative to one another about hinge axes defined by the There are no major elements.

[0067] In FIG. 17, a base 16 is provided as well as the first arm 12 and the second arm 14. In this case, the base 16 is nested between the first arm 12 and the second arm 14. When the first arm 12 and the second arm 14 are pressed together, the base 16 In other embodiments, the base 16 may be partially enclosed within the first adhesive layer. the first arm and the second arm, such as being outside one or both of the first arm and the second arm. may be arranged differently with respect to

[0068] In FIG. 18, the first arm 12 and the second arm 14 extend downward beyond the hinge 17. and form a scissors-type arrangement.

[0069] In FIG. 19, the base 16 is an integral part of the second arm 14, while the first arm 12 pivots relative to the second arm 14 and base 16 about the hinge axis of the hinge 17 .

[0070] Hair styling devices may take many other common forms and configurations. It will be appreciated that, for example, instead of a hinge, a flexible spring and / or a first arm and a second arm may be used. An articulated arrangement may be employed to allow relative movement between the arms.

[0071] Referring to Figures 20 to 23, the relative positions of at least two elements of the hair styling device are An embodiment of a hair styling device using a sensor arrangement that allows for movement sensing is shown. The relative movement may be, for example, the angle and / or distance between two such elements. The two elements whose relative movement, angle or distance is sensed are a first arm 12 and a second arm 13. 4, or one of the arms and another element of the hair styling device. For example, the base If 16 is employed, between the base 16 and one of the first arm 12 and the second arm 14 The relative movement, angle and / or distance of the two can be sensed.

At least a first sensor attached to at least one of the elements to enable detection A sensor arrangement comprising a sensor element is provided. When a single sensor element is used, The sensor component is attached to one element of the hair styling device and is connected to the hair styling device. Measure the relative movement, distance and / or angle between another element of the ring equipment.

[0073] Mechanical, electromechanical, electronic, capacitive, inductive, magnetic, acoustic, electromagnetic, or any other Any suitable sensor based on any technology may be used in such a sensor arrangement. Alternatively, the first sensor component 76 may be an ultrasonic transmitter that uses the same transducer for transmitting and receiving. It may also be a combined transceiver, such as a receiving unit.

[0074] In the embodiment of Figures 20-23, the sensor arrangement includes a first sensor element 76 and a second sensor element 77. The first sensor component 76 and the second sensor component 78 , mechanical, electromechanical, electronic, capacitive, inductive, magnetic, acoustic, electromagnetic, or any other The sensor may include any combination of sensors based on any technology. For example, the first sensor component The first sensor component 76 and the second sensor component 78 may take the form of complementary transmitters and receivers. For example, the second sensor component 78 may be an ultrasonic transmitter, a light emitter, or a sensor (such as a magnet). The first sensor component 76 may be a magnetic field generator, and the second sensor component 76 may be a complementary ultrasonic receiver, ( A second sensor configuration is an optical receiver (e.g., a light-dependent resistor) or a Hall effect sensor. Element 78 may alternatively or additionally take the form of a reflector such as a mirror or an acoustically reflective area. This may optionally be shaped to focus the reflected signal.

[0075] In another alternative, the first component 76 may be configured, configured, or configured differently from the second sensor component 78. may take the form of a receiver, sensor or scanner that interacts with the property. For example, The first component 76 may take the form of an image sensor, and the second sensor component 78 may be a distance A target, reticle, or other object that can be sensed by an image sensor to determine the distance or angle. It may take the form of a scale or other formation.

[0076] In yet another alternative, the first component 76 may take the form of a Hall Effect sensor. Alternatively, the second component 78 may take the form of a magnet. The angle or distance between the respective elements to which the second component 76 and the second component 78 are attached. The sensor is configured to sense the position and / or orientation of the magnet in response to the distance.

[0077] In yet another embodiment, either the first sensor component 76 or the second sensor component 78 Either or both can measure angles or distances, whether relative or absolute. It includes one or more mechanical elements, components, linkages and / or mechanisms that enable For example, the relative movement between the first arm 12 and the second arm 14 can be converted into a rotational movement. A mechanism for converting rotational motion can be provided, and this rotational motion can be sensed using a rotary encoder. Alternatively or additionally, the first sensor component 76 and / or the second sensor The component 78 may be one or more variable resistors, capacitors, inductors, switches, or the like. The first component and / or the second component may include a combination of Interaction with the above variable resistors, capacitors, inductors, switches or combinations thereof It may comprise interacting components that act on it.

[0078] The first sensor component 76 detects the first angle and / or distance based on the sensed angle and / or distance. The first arm 12 outputs a first signal indicative of the angle and / or distance between the first arm 12 and the second arm 14. In the specification, the term "indicating an angle and / or a distance" means that the signal indicates the angle and / or the distance. For example, the first signal may be a first It may indirectly or implicitly indicate the distance between the sensor component and the second sensor component. Therefore, the first signal is a function of the distance between the first arm 12 and the second arm 14 and the angle Although the signal implicitly "indicates" a distance or angle, this signal must be converted to an actual distance or angle. Instead, whatever value is carried by the first signal can be converted into any other form. can be used directly as input without

[0079] Similarly, the distances and angles between elements of the hair styling device may be described as alternatives to one another. Although it is stated that the distance and angle do not actually need to be explicitly sensed or determined. For example, the first sensor component 76 may be an ultrasonic receiver and the second sensor component 78 may be an ultrasonic If the first signal is an ultrasonic wave transmitter, the first signal is an ultrasonic signal generated by the second component 78. can represent the time it takes for the signal to reach the first sensor component 76. , which indicates the distance traversed by the ultrasound signal, but does not require converting time to distance and / or angle. .

[0080] Also, regardless of whether the threshold is converted to an actual distance or angle, the first sensor Whatever the value sensed by the sensor component 76, it determines that some threshold has been met. is sufficient.

[0081] The first signal is output to one or more processors, such as, for example, microprocessor 82. Microprocessor 82 may optionally adjust the first signal as needed. The signal is amplified, filtered or otherwise processed and then passed through a hair styling device 10. Alternatively, a processing circuit (not shown) and / or a The processor may form part of a sensor arrangement that generates the first signal.

[0082] Action may be taken based on the first signal. For example, the first signal may The angle and / or distance between the arm 12 and the second arm 14 falls below a first threshold angle. If the user indicates that the first arm 12 and the second arm 13 are in a locked position, the microprocessor 82 determines whether the user has It may be concluded that the hair bundle 22 was squeezed in the dry cavity 20 between the microphone 4. The air processor 82 directs the heated air from the first slot 48 and the second slot 52. Turn on the heater 66 and motor 32 to evacuate and dry the hair in the drying cavity 20. do.

[0083] The first signal indicates that the angle and / or distance between the first arm 12 and the second arm 14 is If the angle indicates an increase beyond the second threshold angle after It may be concluded that the user has released the tuft 22. Therefore, the microprocessor 82 The heated air is no longer exhausted from the first slot 48 and the second slot 52. Alternatively, after the second threshold angle is exceeded, the heater 66 and the motor 32 are turned off. Only the heater 66 is turned off, and the motor 32 is left running for at least some period of time. This may, for example, be distracting to the user and may cause components within the hair care device 10 to malfunction. Intermittent switching on and off of the fan motor 32, which can increase wear on the can be reduced.

[0084] Optionally or alternatively, the fan may be controlled based on the position of the arm. For example, in response to the second threshold being met, the motor 32 and / or the heater 66 may be turned off. Instead of increasing the speed, the motor power is reduced, slowing the airflow to save power and allow the hair tufts 22 to dry. The amount of air that exits the device when not throttled within cavity 20 may be reduced.

[0085] The first threshold angle and / or distance and the second threshold angle and / or distance are the same, Alternatively, the first threshold angle and / or distance may be greater than the second threshold angle and / or distance. A hysteresis function may be applied so that the When the user maintains the first and second arms very close to a common threshold point, a sudden Prevent switching from occurring.

[0086] Further thresholds may be employed, for example, a third threshold intermediate between the first and second thresholds. A threshold may be used, in which case the heater 66 is turned off while the motor 32 is turned on. If the second threshold is exceeded, both the heater 66 and the motor 32 are turned off.

[0087] Microprocessor 82 also controls the operation of a user operable switch (not shown). For example, the microprocessor 82 may receive user input such as a first Upon sensing that a threshold angle and / or distance has been exceeded, the motor 32 may be turned on. The heater 66, on the other hand, can only be turned on by the user pressing a switch. do.

[0088] Depending on the application, other combinations of thresholds, inputs and controls may be implemented.

[0089] The first signal indicates the status of the first arm 12 and the The first signal may indicate the angle and / or distance between the first arm 12 and the second arm 14. For example, the first signal may indicate a first voltage ( For example, 0V DC), and the first arm and the second arm are at a second threshold angle. A second voltage (e.g., 12V) may be exceeded when the switch is opened. Hysteresis is employed. When the first threshold angle and the second threshold angle are different, such as when Element 76 is a circuit ( Alternatively, the hysteresis may include a microcontroller based on the first signal. It may be implemented by a processor.

[0090] FIG. 20 shows a first component 76 attached to the first arm 12 and a second component 7 8 shows the arrangement attached to the second arm 14. The first arm 12 and the second arm 14 approach each other, the voltage between the first sensor component 76 and the second sensor component 78 The first sensor component 76 may be any suitable sensor, such as any of the techniques described above. The distance 81 between the first arm 12 and the second arm 14 is sensed using the technique. Then, the first sensor component 76 determines a first The arm outputs a first signal indicative of the angle and / or distance between the arm and the second arm.

[0091] FIG. 21 shows a first component 76 attached to the base 16 and a second component 78 attached to the second 14 of the arrangement shown in FIG. X5. The first signal itself is modified to take this into account. or the interpretation of the first signal by microprocessor 82 is adjusted accordingly. .

[0092] FIG. 22 shows a first component 76 and a second component 78 both attached to the first arm 12. The second component 78 is a transmitter, such as an ultrasonic transmitter or a light emitter. and the first component 76 is a complementary receiver such as an ultrasonic receiver or a light-dependent device. The signal output by the second component 78 is transmitted to the section of the second arm 14. 84 before being received by the first component 76. 81 is approximately twice the distance 81 in the arrangement of Figure X5. The first signal itself takes this into account. or the interpretation of the first signal by the first microprocessor 82. is adjusted accordingly. When both components are mounted on the same arm, If wiring is required for the components, the construction can be simplified.

[0093] 23 shows an arrangement in which a link mechanism 86 is provided. The link mechanism 86 is 12, and a first link 88 and a second arm 1 a second link 90 pivotally connected to the first link 88 and the second link 90; and a third link 92 connected to the joint between the first and second arms. As the arm 12 and the second arm 14 move apart together, they slide up and down relative to the base 16. 16. The base 16 is constrained by a complementary slot and tab arrangement (not shown) to The relative lengths and general arrangement of the linkage 86 are such that the first arm 12 and the second arm 14. , the sensitivity and / or reliability of detection may be improved. Any other suitable linkage mechanism may be used. It will be understood that you can get it.

[0094] In order to be able to estimate the distance or angle between the first arm 12 and the second arm 14, Any other arrangement or mechanism for this purpose may be used.

[0095] Additionally, the relative positions of the first sensor component 76 and the second sensor component 78 may cause Therefore, the distance or angle between the first arm 12 and the second arm 14 is measured. If not, the actual distance or angle between the first arm 12 and the second arm 14 is not specified. It may be sufficient to estimate the distance or angle without any transformation. In the hair styling device, a first sensor element 76 and a second sensor element 78 The distance measured between the first arm 12 and the second arm 14 is actually the distance between the corresponding portions of the first arm 12 and the second arm 14. The distance between the first sensor component 76 and the second sensor component 78 is approximately half the distance between the first sensor component 76 and the second sensor component 78. The measured distance is converted into the actual distance between the corresponding portions of the first arm 12 and the second arm 14. There is no need to explicitly convert the first arm 12 and the second arm 14. The distance or angle relationship between the corresponding portions is determined based on the known relationship therebetween and the first signal. It is inferred that

[0096] 24 to 27, upstream of slots 48 and 50, the first arc A tension plate arrangement 110 extends along the rear edge of the first arm 12 and the second arm 14. The tension plate arrangement 110 includes a first tension plate 112 and a second tension plate 113. The first tension plate 112 is a metal leaf spring. 116 is resiliently biased towards the second tension plate 114. The tension plate 112 acts against the tension of the spring 116 in the slot. in the slot of the first arm 12 so that it can move away from the plate 114 It is installed.

[0097] In the illustrated example, the first tension plate 112 has a first guide 118 at one end. and a second guide 120 at the other end, with a first contact surface 119 extending therebetween. The second tension plate 114 includes a third guide 122 at one end. , and a fourth guide 124 at the other end, with a second contact surface 123 extending therebetween. The first contact surface 119 and the second contact surface 123 are coated with a low-friction coating to reduce friction. Although the material is coated with a coating, any other suitable material may be employed.

[0098] In the illustrated implementation, a first guide 118, a second guide 120, and a third guide 122 and the fourth guide 124 is made of an elastomeric material such as silicone that allows the guide to bend. The first guide 118 and the third guide 122 are in the form of a tapered tongue-like projection. The second guide 120 and the fourth guide 124 are also aligned with each other. It is positioned at.

[0099] In use, the first arm 12 and the second arm 14 are pressed together to push the hair tuft 22 into a drying area. Once captured within the zone 20, the first guide 118 and the third guide 122, as well as the second guide The opposing tips of the guide 120 and the fourth guide 124 come into contact with each other, as shown in FIG. The contact between each pair of guides causes the tuft 22 to enter, for example, a drying region. The force of the air flow prevents the particles from leaving the drying area 20.

[0100] As the first and second arms move further toward each other, the first contact surface 119 and the second contact surface 123, the pressure on the bristle tuft 22 is applied by the spring 116. The user may be limited by the hair styling machine pulling the hair away from the scalp. When hair is drawn through the device 10, a friction is generated by the first contact surface 119 and the second contact surface 123. The pressure on the hair bundle 22 provides tactile feedback and indicates that the heated hair is drying the area 20. It helps smooth out the exit.

[0101] Optionally, the hair care device is used to dry hair like a conventional hair dryer. In such a mode (which may be automatically or manually selected), ducts 56 and 60 The airflow 59 exiting the hair dryer is used in the same way as when air from a conventional hair dryer is used. This option can be used to dry the user's hair by pointing the Useful for "dry drying" to reduce moisture levels before the appliance is used in subsequent styling operations. Reduce the bell.

[0102] Although several embodiments have been described with reference to the accompanying drawings, the present invention is not limited to these embodiments. It's not that.
