Generally, airless hair dryers are configured to dry a user's hair by generating alternating electric fields between each tooth of a plurality of teeth located on a body of the airless hair dryer. Each tooth of the plurality of teeth includes a positive electrode and a negative electrode. In some embodiments, the alternating electric fields are generated between a positive (or negative) electrode of one tooth and a negative (or positive) electrode of an adjacent tooth. The plurality of teeth can be arranged in many ways, including in a line or in a matrix.Depending on the arrangement of the positive and negative electrodes inside (or outside) each tooth, alternating electric fields can be generated between each column of teeth in the tooth matrix, each row of teeth in the tooth matrix, both columns and rows in the tooth matrix, or along each diagonal line of the tooth matrix. In some embodiments, the airless hair dryer includes one or more sensors, such as a temperature sensor, a proximity sensor, and / or a steam sensor. Each sensor can measure a quality (such as temperature, proximity, or dryness) of the hair or scalp. These measured qualities can be received by a processor on the airless hair dryer, configured to start, control, or stop the alternating electric field drying.In some embodiments, the airless hair dryer may include one or more alternative heating mechanisms, including heating plates, infrared light-emitting diodes (LEDs). IR), and similar technologies. These alternative heating mechanisms can be used before, during, after, or alternating with alternating electric fields.

[0037] Figure IA is an internal view of an example of an airless hair dryer 100, according to the present technology. In some embodiments, the airless hair dryer 100 is comb-shaped. In some embodiments, the airless hair dryer 100 includes a body 102, a plurality of teeth 105A, 105B, 105C... 105N, at least one temperature sensor 115, at least one steam sensor 120, at least one proximity sensor 125, a processor 130, a current source 135 and a power supply 140.

[0038] In some embodiments, each tooth 105 of the plurality of teeth 105A, 105B, 105C includes a positive electrode HOA-i, 11OA-ii and a negative electrode HOB-i, 11OB-ii. In some embodiments, the positive electrodes 110A-i, 11OA-ii and the negative electrodes 11OB-i, 11OB-ii are alternated within each tooth 105. In this way, a negative electrode (such as the negative electrode 11OB-i) of a tooth (such as tooth 105A) is adjacent to a positive electrode (such as the positive electrode 11OA-ii) of an adjacent tooth (such as tooth 105B). In some embodiments, a first tooth and a last tooth on the airless hair dryer 100 may only include a negative electrode 110B or a positive electrode HOA-i, HOA-ii, respectively. In some embodiments, the plurality of teeth 105A, 105B, 105C... 105N are arranged in a line along the body 102 of the airless hair dryer 100.Although the positive electrodes 1 lOA-i, 1 lOA-ii are illustrated as being on the left side of each tooth of the plurality of teeth 105A, 105B, 105C... 105N and the negative electrodes 1 lOB-i, 1 lOB-ii are illustrated as being on the right side of each tooth of the plurality of teeth 105A, 105B, 105C... 105N, a person skilled in the art will understand that the positive electrodes 1 lOA-i, 1 lOA-ii could be located on the right side and the negative electrodes 1 lOB-i, 1 lOB-ii could be located on the left side.

[0039] In some embodiments, the airless hair dryer 100 includes at least one temperature sensor 115. In some embodiments, the at least one temperature sensor 115 is located in at least one tooth 105 of the plurality of teeth 105A, 105B, 105C... 105N. In some embodiments, the temperature sensor 115 is configured to detect the temperature of a user's scalp.

[0040] In some embodiments, the airless hair dryer 100 includes at least one steam sensor 120 (also referred to herein as "the steam sensor" 120). In some embodiments, the steam sensor 120 is located in the body 102 of the airless hair dryer 100. In some embodiments, the steam sensor 120 is configured to detect the level of dryness of the hair. In some embodiments In terms of implementation, the 120 vapor sensor is a capacitance sensor that converts capacitance into a humidity (or dryness level) reading.

[0041] In some embodiments, the airless hair dryer 100 includes at least one proximity sensor 125. In some embodiments, the proximity sensor 125 is located in at least one tooth 105 of the plurality of teeth 105A, 105B, 105C... 105N. In some embodiments, the proximity sensor 115 is configured to detect the distance between the plurality of teeth 105A, 105B, 105C... 105N and a user's scalp. In some embodiments, the proximity sensor 115 is a contact sensor, configured to detect the user's scalp when the proximity sensor 115 touches the user's scalp.

[0042] The processor 130 can be located inside the body 102 of the airless hair dryer 100. In some embodiments, the processor 130 is coupled in communication with the temperature sensor 115, the steam sensor 120 and / or the proximity sensor 125. In some embodiments, the processor 130 is coupled in communication with the current source 135, the power supply 140, or both.

[0043] In some embodiments, the airless hair dryer 100 includes a current source 135. In some embodiments, the current source 135 is configured to generate alternating electric fields between a negative electrode (such as the negative electrode HOB-i) of a tooth 105 and a positive electrode (such as the positive electrode 11OA-ii) of an adjacent tooth 105, as shown and described in Figures 2A and 2B. In some embodiments, the current source is a radio frequency (RF) generator.

[0044] In some embodiments, the airless hair dryer 100 includes a power source 140. In some embodiments, the power source 140 may be a battery. In some embodiments, the power source 140 may be a rechargeable battery or a disposable battery. In some embodiments, the power source 140 is removable from the body 102 of the airless hair dryer 100. In some embodiments, the power source 140 may include a wired connection (as shown in Figure 3A).

[0045] In operation, the current source 135 generates an alternating electric field between each tooth 105 of the plurality of teeth 105A, 105B, 105C... 105N. Specifically, alternating electric fields are generated between each tooth, between a negative electrode 110A-110 of one tooth 105A and a positive electrode 110A-110 of another tooth 105B, as shown in [Fig. 2A]. Because the positive electrodes 110A and the negative electrodes 110B alternate in the plurality of teeth 105A, 105B, 105C... 105N, alternating electric fields can be generated between each tooth. In some embodiments, the electric fields Alternating fields have frequencies from 1 to 300 MHz. These alternating electric fields can be radio frequency (RF) fields. In some embodiments, the alternating electric fields are configured to dry hair, as illustrated and described in Figures 2A and 2B.

[0046] In some embodiments, the processor 130 is configured to give commands to the temperature sensor 115, the steam sensor 120 and / or the proximity sensor 125. In some embodiments, the temperature sensor 115 measures a user's scalp temperature.

[0047] In some embodiments, the measured temperature is transmitted to the processor 130. In some embodiments, the processor 130 is configured to receive the measured temperature and determine whether the measured temperature reaches or exceeds a temperature threshold. In some embodiments, if the measured temperature reaches or exceeds the temperature threshold, the processor 130 is configured to switch off the airless hair dryer 100.

[0048] In some embodiments, the steam sensor 120 is configured to measure the dryness of the user's hair. In some embodiments, the measured dryness is transmitted to the processor 130. The processor 130 can compare the measured dryness to a dryness threshold. If the measured dryness reaches or exceeds the dryness threshold, the processor 130 can shut off the hairdryer without air.

[0049] In some embodiments, the proximity sensor 125 is configured to determine that the plurality of teeth 105A, 105B, 105C... 105N are in close proximity to the user's hair and / or scalp. In some embodiments, the proximity sensor 125 transmits a measured proximity to the user's hair and / or scalp. In some embodiments, the processor 130 determines whether the measured proximity reaches or exceeds a proximity threshold. If the measured proximity reaches or exceeds the proximity threshold, the processor 130 instructs the current source 135 to generate the alternating electric field. If the measured proximity is below the proximity threshold, the processor 130 may instruct the current source 135 not to generate the alternating electric field and / or to stop generating the alternating electric field.In some embodiments, the processor 130 may alert or otherwise instruct the user to move the airless hair dryer 100 closer to the hair or scalp.

[0050] Figure [Fig. IB] is another internal view of an example of an airless hair dryer 100, according to the present technology. In some embodiments, the airless hair dryer 100 includes a body 102, a plurality of teeth 105A, 105B, 105C... 105N, a plurality of vapor sensors 120A, 120B, 120C...120N, at least one proximity sensor 125 located in the body 102, a processor 130, a current source 135 and a power supply 140.

[0051] In some embodiments, the plurality of vapor sensors 120A, 120B, 120C... 120N may be located within the plurality of teeth 105A, 105B, 105C... 105N. In some embodiments, each tooth 105 of the plurality of teeth 105A, 105B, 105C... 105N includes a vapor sensor 120A, 120B, 120C... 120N. In some embodiments, one or more teeth 105 may not include a vapor sensor. In some embodiments, each vapor sensor of the plurality of vapor sensors 120A, 120B, 120C... 120N is located at the base of each tooth of the plurality of teeth 105A, 105B, 105C... 105N. This allows each steam sensor of the plurality of steam sensors 120A, 120B, 120C...120N to measure the dryness of the hair when combed or brushed by the plurality of teeth 105A, 105B, 105C... 105N.

[0052] During operation, when the airless hair dryer 100 is moved through the hair, each vapor sensor of the plurality of vapor sensors 120A, 120B, 120C...120N can independently measure the hair's dryness level. In some embodiments, the plurality of vapor sensors 120A, 120B, 120C...120N is a plurality of capacitance sensors that convert the capacitance into a moisture (or dryness level) reading. In such embodiments, when a dryness measured from any steam sensor of the plurality of steam sensors 120A, 120B, 120C...120N reaches or exceeds the dryness threshold, the processor 130 can order the current source to stop supplying current to the tooth of the plurality of teeth 105A, 105B, 105C...105N, including the steam sensor that measured the dryness level which reaches or exceeds the dryness level threshold.In this way, an alternating electric field will not be generated between the tooth and an adjacent tooth of the plurality of teeth 105A, 105B, 105C... 105N but will always be generated between all the other teeth of the plurality of teeth 105A, 105B, 105C. In some embodiments, when even a vapor sensor of the plurality of vapor sensors 120A, 120B, 120C...120N reaches or exceeds the dryness level threshold, the current source 135 stops generating alternating electric fields towards all the teeth of the plurality of teeth 105A, 105B, 105C... 105N, that is, stops supplying current to the plurality of teeth 105A, 105B, 105C... 105N.

[0053] Figure 2A is a close-up view of two teeth 205A, 205B respectively from a plurality of teeth, according to the present technology. The teeth 205A, 205B can be single teeth within a plurality of teeth, as shown in Figures IA and IB. Tooth 205A can be referred to here as "a tooth". A person skilled in the art should understand that any tooth in the plurality of teeth described herein can be "a tooth". Similarly, tooth 205B can be referred to here as an "adjacent tooth". A person skilled in the art should understand that any tooth directly next to another tooth can be an "adjacent tooth". The adjacent tooth 205B can The tooth 205B can be arranged in any direction from tooth 205A. In some embodiments, such as when the plurality of teeth is arranged in a line along the body (such as body 102, 302) of the airless hair dryer (such as airless hair dryer 100, 300), the adjacent tooth 205B can be the next tooth in the line. In some embodiments, such as when the plurality of teeth is arranged in a matrix (as shown in Figures 3C to 3D and 4A to 5C), the adjacent tooth 205B can be one or all of the teeth directly next to tooth 205B. In such embodiments, the adjacent tooth 205B can be the tooth in any of the eight cardinal directions from tooth 205A. In some embodiments, a tooth 205A may have multiple adjacent teeth 205B.When the plurality of teeth are arranged according to a matrix, the adjacent tooth 205B can be a tooth in the same row of the matrix, the same column of the matrix, the same diagonal row of the matrix, or a combination of these.

[0054] In some embodiments, the teeth 205A, 205B each include a positive electrode HOA-i, 11OA-ii and a negative electrode HOB-i, 11OB-ii. In some embodiments, the positive electrodes HOA-i, 11OA-ii are alternated with the negative electrodes HOB-i, 11OB-ii. In some embodiments, the orientation of the positive electrodes HOA-i, 11OA-ii and the negative electrodes 110B-i, 11OB-ii determines which tooth is the adjacent tooth when the plurality of teeth are arranged in a matrix. For example, if the positive electrodes HOA-i, 1 lOA-ii and the negative electrodes HOB-i, 1 lOB-ii are arranged along a diagonal line from southwest to northeast inside (or on) each tooth of the plurality of teeth, the adjacent teeth 205B are the tooth directly southwest of tooth 205A and the tooth directly northeast of tooth 205A.In some embodiments, a current source (such as the current source 135 in Figures IA and IB) is configured to supply a current to each electrode 11OA-i, 11OA-ii, 11OB-i, 110B-ii of the plurality of teeth to generate an alternating electric field EF between one electrode (such as the negative electrode 11OB-i) in tooth 205A and a second electrode (such as the positive electrode 11OA-ii) in the adjacent tooth 205B. Although the alternating electric field EF is illustrated as being generated between the negative electrode 11OB-i of tooth 205A and the positive electrode 11OA-ii of the adjacent tooth 205B, it should be understood that the alternating electric field could be between the positive electrode 11OA-i of tooth 205A and the negative electrode 11OB-ii of the adjacent tooth 205B depending on the orientation of electrodes HOA-i, 11OA-ii, 110B-i, 11OB-ii and / or the orientation of tooth 205A and the adjacent tooth 205B.

[0055] In certain embodiments, the electrodes HOA-i, HOA-ii, OB-i, and OB-ii are located inside each tooth of the plurality of teeth. In certain embodiments, the electrodes HOA-i, HOA-ii, OB-i, and OB-ii are located on the surface of each tooth. In some embodiments, the electrodes HOA-i, 1 lOA-ii, 1 lOB-i, 1 lOB-ii are contacts, such as copper contacts.

[0056] In some embodiments, tooth 205A and the adjacent tooth 205B are separated by a distance D. In some embodiments, each tooth in the plurality of teeth is separated by a distance D. In some embodiments, the distance D is the maximum distance the teeth can be separated while still generating the alternating electric field EF. In other embodiments, the distance D is any spacing distance that generates the alternating electric field EF. In some embodiments, the alternating electric field EF has a frequency of 1 to 300 MHz. In some embodiments, the alternating electric field EF is a radio frequency (RF) field.

[0057] Figure 2B is a close-up view of a positive electrode 11OA-i of a tooth (such as tooth 205A) and a negative electrode 11OB-ii of an adjacent tooth (such as the adjacent tooth 205B), according to the present technology. In some embodiments, the distance D may be substantially equal to the distance between the positive electrode 11OA-i of one tooth and the negative electrode 11OB-ii of another tooth (adjacent tooth), such as when the electrodes 11OA-i, 11OB-ii are located outside each tooth.

[0058] In some embodiments, the alternating electric field EF is generated between the positive electrode 11OA-i of a tooth and the negative electrode 11OB-ii of an adjacent electrode. In some embodiments, the alternating electric field EF has a frequency between 1 and 300 MHz.

[0059] During operation, the current source 235 supplies a current to the electrodes 1 lOA-i, 1 lOB-ii. Electrodes 1 lOA-i, 1 lOB-ii can generate an alternating electric field EF between them. The alternating energy of the alternating electric field EF can cause the continuous reorientation of polar molecules in the water so that they face opposite poles, in the same way that magnets move in an alternating magnetic field. In this way, the strands of hair (illustrated as having positive (plus sign) and negative (minus sign) poles) can orient themselves towards electrodes 1 lOA-i, 1 lOB-ii. This movement of polar molecules in the water causes friction, which allows the water in the strands of hair to evaporate rapidly through them, effectively drying the hair.

[0060] Figures 3A to 3D are perspective views of examples of airless hair dryers 300, according to the present technology. In some embodiments, the airless hair dryer 300 includes a body 302, a handle 303 and a plurality of teeth 305A, 305B, 305C... 305N. In some embodiments, the handle 303 may be an integral part of the body 302, as shown in Figures 3A. and 3B. In some embodiments, the handle 303 may be a separate component of the body 302, as shown in Figures 3C and 3D. Those skilled in the art should recognize that any handle configuration can be incorporated into any form factor of the airless hair dryer 300, including a single body / handle component 302, 303, a separate handle 303, a handle 303 removable from the body 302, or the like. The handle 303 may have any shape, including two-dimensional, three-dimensional, cylindrical, rectangular, organic, or the like.

[0061] In some embodiments, the plurality of teeth 305A, 305B, 305C... 305N are arranged in a line along all or a portion of the body 302, as shown in Figures 3A and 3B. In some embodiments, the airless hair dryer 300 includes a plurality of infrared (IR) light-emitting diodes (LEDs) 350A, 350B, 350C.

[0062] In operation, the IR LEDs 350A, 350B, and 350C are configured to emit or transfer IR energy to the hair. In some embodiments, the IR energy has a wavelength between 0.78 and 1000 pm. In some embodiments, the IR energy is shortwave IR (approximately 0.78 to 2 pm), mediumwave IR (approximately 2 to 4 pm), and / or longwave IR (approximately 4 to 1000 pm). In some embodiments, the IR LEDs 350A, 350B, and 350C are configured to dry the hair while alternating electric fields are generated between the plurality of teeth (as described in Figures 2A and 2B). In some embodiments, the 350A, 350B, 350C IR LEDs are configured to dry hair independently of alternating electric fields, such as before the generation of alternating electric fields, after the generation of alternating electric fields, or both.In some embodiments, the alternating electric fields and the IR LEDs 350A, 350B, 350C alternate when a user moves the airless hair dryer 300 through their hair. In some embodiments, a steam sensor (such as the steam sensor 120) detects a hair dryness level, and when the dryness level reaches or exceeds a specified level, the alternating electric fields are switched off and the IR LEDs 350A, 350B, 350C are switched on.

[0063] Figure 3A is an airless hair dryer 300 having a "comb with handle" form factor. In some embodiments, the airless hair dryer 300 includes a power connector 345 configured to facilitate a wired connection (not shown) to an external power outlet or power source.

Method 700 can be carried out by any of the airless hair dryers (100, 200, 300, 400, 500, 600) described herein. In some embodiments, the airless hair dryer includes a body (such as body 102, 302, 402, 502, 602) and at least one plurality of teeth (such as the plurality of teeth 105A, 105B, 105C...105N, 205A, 205B, 305A, 305B, 305C, 405A, 405B, 405C, 505A, 505B, 505C, 605A, 605B, 605C). In some embodiments, the airless hair dryer also includes a processor (such as processor 130), a current source (such as current source 135, 235), and / or a power supply (such as power supply 140).In some embodiments, the airless hair dryer also includes one or more temperature sensors (such as temperature sensor 115), one or more proximity sensors (such as proximity sensor 125), one or more steam sensors (such as steam sensor 120 and / or the plurality of steam sensors 120A, 120B, 120C...120N), and / or one or more infrared light-emitting diodes (IR LEDs) (such as the plurality of IR LEDs 350A, 350B, 350C).

[0085] In block 705, the plurality of teeth is displaced into the hair (or hair strands, such as hair strands 2000). In some embodiments, the plurality of teeth is located on the body of the airless hair dryer. The body may have a first face (such as the first face 402A, 502A, 602A) and / or a second face (such as the second face 402B, 502B, 602B). In some embodiments, the plurality of teeth may be located on the first face and / or the second face, and on one or more sides (such as a front side of the first face FS1, a front side of the second face FS2, a first side S1 and / or a second side S2) of the first face and / or the second face.

[0086] Optionally, in block 710, the first face and the second face are clamped together (as shown in Figures 4B, 5B and 6B). In some embodiments, the plurality of teeth on the first face interlock or alternate with the plurality of teeth on the second face.

[0087] At block 715, electric fields (also referred to herein as alternating electric fields) are generated between positive electrodes (such as positive electrodes 110A, 11OA-i, 11OA-ii) of one tooth in the plurality of teeth and negative electrodes (such as negative electrodes 110B, HOB-i, 11OB-ii) of an adjacent tooth in the plurality of teeth. As described herein, an adjacent tooth may refer to one or more teeth in the plurality of teeth directly next to another tooth of The plurality of teeth. When the plurality of teeth is arranged in a line (as shown in Figures IA and IB, 3A and 3B, 5A to 5C and 6A to 6C), the adjacent tooth is one or more teeth located directly on either side of a tooth in the plurality of teeth. When the plurality of teeth is arranged in a matrix (as shown in Figures 3C and 3D, 4A to 4C and 5A to 5C), the adjacent tooth can be one or more teeth in any cardinal direction, along any line, such as within the same column or row, or diagonally. When the airless hair dryer includes more than one plurality of teeth (as shown in Figures 4A to 4C, 5A to 5C and 6A to 6C), the adjacent tooth can be a tooth of the same plurality of teeth as the tooth, or a tooth of a different plurality of teeth than the tooth.

[0088] At block 720, the hair is dried. In some embodiments, the current source supplies a current to the electrodes. The electrodes can generate alternating electric fields between them. The alternating energy of the electric fields causes a continuous reorientation of the polar molecules in the water so that they face opposite poles, in the same way that magnets move in an alternating magnetic field. In this way, the hair strands, having positive and negative poles, can be oriented towards the electrodes. The movement of the polar molecules in the water thus causes friction, which allows the water in the hair strands to evaporate rapidly, effectively drying the hair.

[0103] Figure 10 is an example of method 1000 for using an airless hair dryer with an infrared light-emitting diode, according to the present technology. Method 1000 can be carried out by any of the airless hair dryers (100, 200, 300, 400, 500, 600) described herein. In some embodiments, the airless hair dryer includes a body (such as body 102, 302, 402, 502, 602) and at least one plurality of teeth (such as the plurality of teeth 105A, 105B, 105C...105N, 205A, 205B, 305A, 305B, 305C, 405A, 405B, 405C, 505A, 505B, 505C, 605A, 605B, 605C). In some embodiments, the airless hair dryer also includes a processor (such as processor 130), a current source (such as current source 135, 235), and / or a power supply (such as power supply 140).In some embodiments, the airless hair dryer also includes one or more temperature sensors (such as temperature sensor 115), one or more proximity sensors (such as proximity sensor 125), one or more steam sensors (such as steam sensor 120 and / or the plurality of steam sensors 120A, 120B, 120C...120N), and / or one or more. several infrared light-emitting diodes (IR LEDs) (such as the plurality of IR LEDs 350A, 350B, 350C).

[0104] In block 1005, the plurality of teeth is displaced into the hair (or hair strands, such as hair strands 2000). In some embodiments, the plurality of teeth is located on the body of the airless hair dryer. The body may have a first face (such as the first face 402A, 502A, 602A) and / or a second face (such as the second face 402B, 502B, 602B). In some embodiments, the plurality of teeth may be located on the first face and / or the second face, and on one or more sides (such as a front side of the first face FS1, a front side of the second face FS2, a first side S1 and / or a second side S2) of the first face and / or the second face.

[0105] Optionally, in block 1010, the first face and the second face are clamped together (as shown in Figures 4B, 5B and 6B). In some embodiments, the plurality of teeth on the first face interlock or alternate with the plurality of teeth on the second face.

[0106] At block 1015, electric fields (also referred to herein as alternating electric fields) are generated between positive electrodes (such as positive electrodes 110A, 11OA-i, 11OA-ii) of one tooth in the plurality of teeth and negative electrodes (such as negative electrodes 110B, HOB-i, 11OB-ii) of an adjacent tooth in the plurality of teeth. As described herein, an adjacent tooth can refer to one or more teeth in the plurality of teeth directly next to another tooth in the plurality of teeth. When the plurality of teeth is arranged in a line (as shown in Figures IA and IB, 3A and 3B, 5A to 5C and 6A to 6C), the adjacent tooth is one or more teeth located directly on either side of a tooth in the plurality of teeth.When the plurality of teeth is arranged in a matrix (as shown in Figures 3C and 3D, 4A to 4C, and 5A to 5C), the adjacent tooth can be one or more teeth in any cardinal direction, along any line, such as within the same column or row, or diagonally.

[0107] In block 1020, the hair is dried with alternating electric fields. In some embodiments, the current source supplies a current to the electrodes. The electrodes can generate alternating electric fields between them. The alternating energy of the alternating electric fields causes a continuous reorientation of the polar molecules in the water so that they face opposite poles, in the same way that magnets move in an alternating magnetic field. In this way, strands of hair having positive and negative poles can be oriented towards the electrodes. In this way, the movement of polar molecules in the water causes friction, which allows the water in the hair strands to evaporate rapidly through the hair strands, effectively drying the hair.

[0108] In block 1025, the hair is dried with one or more IR LEDs. In some embodiments, the IR LEDs emit or transfer IR energy to the hair. In some embodiments, the IR energy has a wavelength between 0.78 and 1000 pm. In some embodiments, the IR energy is shortwave IR (approximately 0.78 to 2 pm), mediumwave IR (approximately 2 to 4 pm), and / or longwave IR (approximately 4 to 1000 pm). In some embodiments, block 1020 and block 1025 occur simultaneously, i.e., the IR LEDs dry the hair while alternating electric fields are generated between the plurality of teeth. In some embodiments, block 1020 and block 1025 occur consecutively.In some embodiments, the IR LEDs are configured to dry hair independently of alternating electric fields, such as before the generation of alternating electric fields, after the generation of alternating electric fields, or both. In some embodiments, blocks 1020 and 1025 are alternated; that is, the alternating electric fields and the IR LEDs 350A, 350B, 350C are alternated when a user moves the airless hairdryer 300 through the hair.

In some embodiments, the airless hair dryer includes a body (such as body 102, 302, 402, 502, 602) and at least one plurality of teeth (such as the plurality of teeth 105A, 105B, 105C...105N, 205A, 205B, 305A, 305B, 305C, 405A, 405B, 405C, 505A, 505B, 505C, 605A, 605B, 605C). In some embodiments, the airless hair dryer also includes a processor (such as processor 130), a current source (such as current source 135, 235), and / or a power supply (such as power supply 140).In some embodiments, the airless hair dryer also includes one or more temperature sensors (such as temperature sensor 115), one or more proximity sensors (such as proximity sensor 125), one or more steam sensors (such as steam sensor 120 and / or the plurality of steam sensors 120A, 120B, 120C...120N), and / or one or more infrared light-emitting diodes (IR LEDs) (such as the plurality of IR LEDs 350A, 350B, 350C).

In some embodiments, the plurality of teeth is located on the body of the airless hair dryer. The body may have a first face (such as the first face 402A, 502A, 602A) and / or a second face (such as the second face 402B, 502B, 602B). In some embodiments, the plurality of teeth may be located on the first face and / or the second face, and on one or more sides (such as a front side of the first face FS1, a front side of the second face FS2, a first side S1 and / or a second side S2) of the first face and / or the second face.

[0111] At block 1110, electric fields (also referred to herein as alternating electric fields) are generated between positive electrodes (such as positive electrodes 110A, 11OA-i, 11OA-ii) of one tooth in the plurality of teeth and negative electrodes (such as negative electrodes 110B, 11OB-i, 11OB-ii) of an adjacent tooth in the plurality of teeth. As described herein, an adjacent tooth can refer to one or more teeth in the plurality of teeth directly next to another tooth in the plurality of teeth. When the plurality of teeth is arranged in a line (as shown in Figures IA and IB, 3A and 3B, 5A to 5C and 6A to 6C), the adjacent tooth is one or more teeth located directly on either side of a tooth in the plurality of teeth.When the plurality of teeth is arranged in a matrix (as shown in Figures 3C and 3D, 4A to 4C, and 5A to 5C), the adjacent tooth can be one or more teeth in any cardinal direction, along any line, such as within the same column or row, or diagonally. When the airless hair dryer includes more than one plurality of teeth (as shown in Figures 4A to 4C, 5A to 5C, and 6A to 6C), the adjacent tooth can be a tooth from the same plurality of teeth as the tooth in question, or a tooth from a different plurality of teeth.

[0112] In block 1115, the dryness (or level of dryness) of the hair is detected. In some embodiments, the level of dryness can be measured by the steam sensor. In some embodiments, the steam sensor can be located in the body of the airless hair dryer, or in one or more teeth of the plurality of teeth. In some embodiments, the steam sensor can be located at the base of one or more teeth of the plurality of teeth. In some embodiments, there can be a steam sensor in each tooth of the plurality of teeth.

[0113] In decision block 1120, it is determined whether the measured dryness level reaches or exceeds a dryness threshold. If the dryness level reaches or exceeds the dryness threshold, process 1100 proceeds to block 1125.

[0114] At block 1125, the electric fields are turned off or otherwise deactivated. In some embodiments, the current source stops emitting a current. In In some embodiments, the power source stops transmitting power.

[0115] At block 1130, the hair is dried with one or more IR LEDs. In some embodiments, the IR LEDs emit or transfer IR energy to the hair. In some embodiments, the IR energy has a wavelength between 0.78 and 1000 pm. In some embodiments, the IR energy is shortwave IR (approximately 0.78 to 2 pm), mediumwave IR (approximately 2 to 4 pm), and / or longwave IR (approximately 4 to 1000 pm). In some embodiments, block 1020 and block 1025 occur simultaneously, i.e., the IR LEDs dry the hair while alternating electric fields are generated between the plurality of teeth. In some embodiments, block 1020 and block 1025 occur consecutively.In some embodiments, the IR LEDs are configured to dry hair independently of alternating electric fields, such as before the generation of alternating electric fields, after the generation of alternating electric fields, or both. In some embodiments, blocks 1020 and 1025 are alternated; that is, the alternating electric fields and the IR LEDs 350A, 350B, 350C are alternated when a user moves the airless hairdryer 300 through the hair.

[0116] In decision block 1135, it is determined whether the measured dryness level reaches or exceeds a second dryness threshold. In some embodiments, the second dryness threshold is a higher (drier) dryness level than the first dryness threshold. If the dryness level reaches or exceeds the second dryness threshold, process 1100 proceeds to block 1125.

[0117] At block 1140, one or more IR LEDs are turned off or otherwise disabled. In some embodiments, the power supply stops supplying power. In some embodiments, the processor commands one or more IR LEDs to turn off.

[0118] Returning to decision block 1135, if the dryness level does not reach or exceed the second dryness threshold, process 1100 returns to block 1130.
