Description

Hair care method and hair care device

The present invention relates to a hair care method and a hair care device for hair styling using a hair care device including a charged particle generation device that generates charged particles.

Conventionally, when styling hair, a hair dryer that sends warm air to the hair while combing the hair and a hair care device that sends warm air containing negative ions to the hair while combing the hair are used. Documents disclosing such hair dryers and hair care devices include Japanese Patent Application Laid-Open No. 2007-229316 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2011-183221 (Patent Document 2).

The hair dryer disclosed in Patent Document 1 includes a casing of a cylindrical portion provided with a discharge port, a heating device and a blower that are arranged in the case and send warm air from the discharge port. Animal hair (high-density brush hair) and resin hair (single-wire brush hair) are arranged in a line along the axial direction of the housing on the planting surface provided in the housing. Only the resin hairs are arranged in the outermost row in the direction perpendicular to the axial direction, and the resin hairs and animal hairs are arranged inside the outermost row.

When hair is set with such a hair dryer, warm air is blown onto the hair group while applying a tensile force to the hair (hair group) with animal hair. Thereby, the fiber of hair can be tightened and hair quality, such as gloss of hair, can be improved.

The hair care device disclosed in Patent Document 2 includes a brush frame body in which a blow outlet, an ion outlet, and a group of single-line brush hairs are provided on the front surface and tension combs are provided on both side surfaces, and a main body portion connected to the brush frame body And a blower, a heater, and a discharge body, which are arranged in the main body and for sending warm air containing negative ions from the blowout port and the ion outlet.

When hair is set using such a hair care device, for example, when curling is performed, the hair group is combed while supplementing the hair with a tension comb while rotating the hair care device in the circumferential direction. Thereby, since a tensile force can be made to act on a hair group reliably, a curling process can be performed effectively.

A hair care device provided with a hot air generator in a hair brush disclosed in Japanese Patent No. 3870617 (Patent Document 3) includes a columnar gripping portion gripped by a user and a brush portion that is detachably connected in the axial direction of the gripping portion. And. On the peripheral surface of the brush portion, a large number of brush hairs are erected in a plurality of rows in a range of about a half circumference excluding a part in the circumferential direction. Between the rows of brush bristles, air outlets for blowing warm air are provided in a row.

The grip part has a suction opening at one end and an air passage is formed inside. A blower and a heating device are arranged in the air passage. The air passage is open at the tip of the air passage at the end on the brush portion side and sends out airflow in the direction of the brush portion.

In the hair care device configured as described above, the user performs hair shaping by holding the holding portion and sliding the brush hair on the hair. At this time, when the blower and the heating device are driven, outside air flows into the air passage from the suction port, and the heated airflow is sent out from the blowout port. Thereby, warm air is given to the hair which contacts a brush hair. Further, Patent Document 1 discloses a hair care device that is provided with high-density brush hair that catches hair and applies a pulling force inside one row inside the outermost row of brush hairs, and can shape the heated hair. The

Further, Japanese Patent No. 4232695 (Patent Document 4) discloses a hair dryer that further includes an ion generator on a hairbrush provided with a warm air generator, and moistens the hair by blowing ions onto the hair along with the hair. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following embodiments, the same or common parts are denoted by the same reference numerals in the drawings, and description thereof will not be repeated.

<First Embodiment>
FIG. 1 is an external perspective view of the hair care device of the present embodiment. 2 and 3 are a side sectional view and a top sectional view of the hair care device of the present embodiment. A hair care device 1 according to the present embodiment will be described with reference to FIGS. 1 to 3.

The hair care device 1 constitutes a hair dryer with a brush, and includes a columnar gripping portion 10 gripped by a user and a brush portion 30 that is detachably connected in the axial direction of the gripping portion 10. A large number of brush hairs 31 are erected in a line in a range of about a half circumference excluding a part of the brush portion 30 in the circumferential direction.

The brush unit 30 includes a large number of air outlets 33 provided around the bristles 31. The blower outlet 33 includes a blower outlet 33a composed of a small hole and a blower outlet 33b provided on the side surface of the brush portion 30. The blower outlets 33 a are provided in a row between the rows of brush bristles 31. The blower outlets 33b are provided in a row on both side surfaces of the brush part 30 so as to sandwich the planting region of the brush hair 31 in the circumferential direction of the brush part 30.

The power cord 17 is led out from one end of the grip portion 10 in the axial direction. The grip 10 has a suction port 15 formed of a large number of small holes provided around the power cord 17. As shown in FIG. 2, an operation unit 12 having operation switches 18 and 19 is provided at the end of the grip unit 10 on the brush unit 30 side. The operation switch 18 switches on / off of the blower 3 and the charged particle generator 20 described later. The operation switch 19 switches on / off of the heater 4 as a heating device described later.

Further, the grip portion 10 is provided with a reduced diameter portion 11 adjacent to the operation portion 12. The reduced diameter portion 11 has an outer peripheral surface formed in a conical surface, and reduces the outer diameter of the grip portion 10 from the suction port 15 side toward the operation portion 12. The user can easily perform the movement operation of the hair care device 1 and the switching operation of the operation switches 18 and 19 by gripping the reduced diameter portion 11 having a small outer diameter adjacent to the operation portion 12.

At the other end of the grip portion 10 in the axial direction, a connecting portion 16 that fits the brush portion 30 is provided. A connection port 16 a opens at the end surface of the connection portion 16. The connection port 16a is protected by a mesh or a grid formed in a continuous hexagonal shape in order to prevent foreign matter from entering.

The cavity portion 25 is provided inside the grip portion 10, and the cavity portion 36 is provided inside the brush portion 30. The hollow portion 25 and the hollow portion 36 form an air passage 24 that communicates with the inside of the grip portion 10 and the brush portion 30. The hollow portion 36 is formed so as to be biased to one side with respect to the center of the connection port 16a, and the blowout port 34 is provided at a shift portion from the connection port 16a. A connecting portion is provided at one end of the brush portion 30 and is connected so as to be engaged with the connecting portion 16. The bristles 31 are arranged toward the tip of the brush portion 30 when viewed from the blower outlet 34.

The blower 3 is arranged in the hollow portion 25 so as to face the suction port 15. The blower 3 includes an axial fan driven by a blower motor 3a. The blower 3 may be formed by a centrifugal fan. When the blower 3 is driven, an air flow is guided from the suction port 15 to the outlet 33 and the outlet 34 by the air passage 24. The blower outlet 33 includes a blower outlet 33a arranged between the brush bristle rows and a 33b arranged outside the region of the brush bristle rows.

The drive circuit 5 is disposed adjacent to the downstream of the blower 3 in the hollow portion 25. The blower 3, the heater 4 and the charged particle generator 20 are driven by the drive circuit 5. By disposing the drive circuit 5 in the air passage 24, the blower motor 3a and the drive circuit 5 can be cooled by the airflow flowing through the air passage 24.

In the hollow portion 25, a throttle portion 26 is provided that inclines the inner wall surface downstream of the blower 3 to narrow the flow path. The outer peripheral surface of the reduced diameter portion 11 is formed along the throttle portion 26, and the outer diameter of the reduced diameter portion 11 can be easily reduced. A coil-shaped heater 4 is disposed in the throttle unit 26 to raise the temperature of the airflow. An ion mixing unit 27 is provided downstream of the throttle unit 26.

The ion mixing part 27 has a flow area substantially equal to the inlet 26 a at the downstream end of the throttle part 26. Since the airflow flowing through the restrictor 26 is restricted in the flow path, the flow velocity is increased and guided toward the center of the flow path. For this reason, the airflow heated by the heater 4 flows through the central portion of the ion mixing unit 27. The channel area of the ion mixing unit 27 may be wider than the inlet 26a.

A flat mounting surface 27a exposed on the outer surface of the operation unit 12 is formed on the peripheral surface of the ion mixing unit 27, and the charged particle generator 20 having a rectangular shape in plan view is detachably disposed on the mounting surface 27a. A contact point (not shown) is exposed on the wall surface adjacent to the reduced diameter portion 11 of the operation unit 12 and is connected to the drive circuit 5. A terminal 51 to which power is supplied via a contact is provided on the end face of the charged particle generator 20. The outer peripheral surface of the charged particle generator 20 is covered with a cover 23 that is attached to and detached from the operation unit 12.

FIG. 4 is a schematic external view of a charged particle generator mounted on the hair care device of the present embodiment. The charged particle generator 20 will be described with reference to FIG. In the present embodiment, an ion generator that generates positive and negative ions will be described as an example of the charged particle generator.

The charged particle generator 20 has a pair of needle-like discharge electrodes 21. The charged particle generator 20 faces the air passage 24 through an opening 27b that opens on the mounting surface 27a. The discharge electrode 21 is disposed at one end of the air passage 24 that is the front portion of the charged particle generator 20 in the air flow direction. Thus, one end of the charged particle generator 20 is arranged facing the opening 27b. A circuit board 50 is housed at the other end, which is the rear part of the charged particle generator 20 away from the discharge electrode 21, and a terminal 51 is provided at the rear end surface.

The charged particle generator 20 is provided with a cover portion 22 that covers the discharge electrode 21. The cover portion 22 has a through hole 22a that the discharge electrode 21 faces. When the charged particle generator 20 is attached and detached by the cover portion 22, the discharge electrode 21 is protected by preventing contact between the user's finger and the discharge electrode 21.

The charged particle generator 20 generates high-voltage electricity with a built-in circuit board 50. A positive high voltage pulse is applied to one discharge electrode 21, and a negative high voltage pulse is applied to the other discharge electrode 21. Thereby, corona discharge is generated at the tip of the discharge electrode 21. Corona discharge of the discharge electrode 21 to which a positive voltage is applied ionizes water molecules in the air and generates hydrogen ions. This hydrogen ion is clustered with water molecules in the air by solvation energy. As a result, air ions (positive ions) composed of H ⁺ (H ₂ O) _m (m is an arbitrary natural number) are generated as positively charged particles and mixed with the airflow.

In addition, oxygen molecules or water molecules in the air are ionized by corona discharge of the discharge electrode 21 to which a negative voltage is applied, and oxygen ions are generated. This oxygen ion is clustered with water molecules in the air by solvation energy. As a result, air ions (negative ions) composed of O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated as negatively charged particles, and are mixed into the air stream.

At this time, the pair of discharge electrodes 21 are arranged in the circumferential direction of the ion mixing unit 27 with a predetermined amount away from each other in the circumferential direction of the ion mixing unit 27. In addition, an air flow whose flow velocity is increased by the throttle portion 26 upstream of the ion mixing portion 27 flows through the central portion of the ion mixing portion 27. For this reason, both positive and negative ions generated at the discharge electrode 21 in the peripheral portion are attracted and mixed by the negative pressure in the airflow flowing through the central portion of the ion mixing portion 27.

When the airflow flows through the periphery of the ion mixing unit 27, ions that collide with the inner wall of the air passage 24 and disappear are increased by the airflow. For this reason, it is possible to reduce the disappearance of ions by flowing the central portion of the ion mixing unit 27 in the airflow that has passed through the throttle unit 26 and sucking and mixing positive and negative ions generated at the discharge electrode 21. Further, if the discharge electrode 21 is arranged at the center of the ion mixing unit 27, the pressure loss of the air passage 24 becomes large. For this reason, ventilation efficiency can be improved by arrange | positioning the discharge electrode 21 in the surrounding part of the ion mixing part 27. FIG.

In addition, as shown in FIG. 2, a cavity 36 is disposed on the same side as the discharge electrode 21 with respect to the axial center of the throttle portion 26, and the brush bristle is on the opposite side of the discharge electrode 21 with respect to the axial center of the throttle portion 26. 31 is arranged. Thereby, ions generated at the discharge electrode 21 are smoothly guided to the cavity 36. Therefore, a large number of positive and negative ions can be delivered from the air outlet 33a between the bristles 31 and the air outlet 33b on the side of the brush portion 30.

In this case, the concentration of either positive ions or negative ions in the air passage 24 from the charged particle generator 20 to the

outlets

34, 33a, 33b is greater than 5000 / cm ³ and 50000000. It is preferably less than / cm ³ .

When the concentration of either positive ions or negative ions is 5000 / cm ³ or less, the high-density brush hair 31b and the hair (hair group) 38 (FIG. 7, FIG. 8) may not be able to be sufficiently removed. As a result, the effect of improving gloss, the effect of suppressing the damage of the cuticle, the effect of suppressing the occurrence of split ends and broken hairs, etc. may not be sufficiently exhibited.

When the concentration of either positive ions or negative ions is 50000000 / cm ³ or more, both positive and negative air ions disappear due to collision between positive ions and negative ions. . As a result, a sufficient amount of both positive ions and negative ions cannot be supplied to the hair 38, and the effect of improving gloss, the effect of suppressing cuticle damage, the effect of suppressing the occurrence of split ends and cut hairs, etc. May not be fully demonstrated.

The cover 23 is formed of a resin molded product, and opens and closes by sliding in the axial direction of the operation unit 12. Locking claws 23a are provided on both sides of the cover 23 on the brush part 30 side, and locking claws 23b are provided on both sides of the reduced diameter part 11 side. A pressing rib 23 d is provided on the end surface of the cover 23 on the brush portion 30 side.

Also, the cover 23 can be slid and removed from the terminal side to the discharge electrode 21 side, the charged particle generator 20 can be attached and detached, and the discharge electrode 21 can be cleaned and the charged particle generator 20 can be replaced.

A grid-like shielding rib 23 c close to the outer peripheral surface of the charged particle generator 20 is provided on the inner surface of the cover 23. The shielding rib 23 c shields between the front part and the rear part of the charged particle generator 20 inside the cover 23. In the charged particle generator 20, the terminal 51 disposed on the rear end surface may come into contact with the contact point, and a high-temperature air flow may leak from the gap between the opening 27 b and the front end surface of the charged particle generator 20. At this time, the airflow is shielded by the shielding ribs 23c, and the temperature rise of the circuit board 50 disposed at the rear of the charged particle generator 20 can be prevented.

FIG. 5 is an axial sectional view showing the internal structure of the brush portion of the hair care device of the present embodiment, and is a sectional view along the axis of the brush portion 30. FIG. 6 is a cross-sectional view in a direction perpendicular to the axis showing the internal structure of the brush portion of the hair care device of the present embodiment, and is a cross-sectional view taken along the line AA in FIG. With reference to FIG. 5 and FIG. 6, the structure of the brush part 30 is demonstrated.

As shown in FIGS. 5 and 6, the plurality of brush hairs 31 constitute a plurality of single-line brush hair rows 32 to be described later and two high-density brush hair rows (not shown) to be described later.

The single-line brush bristle row 32 is formed by arranging a single bristle bristles (single-line brush bristles) 31 a having a rounded tip along the axial direction of the brush part 30. The single-line brush bristle rows 32 are arranged in parallel at predetermined intervals in a range (circumferential surface) of about a half circumference excluding a part of the brush portion 30 in the circumferential direction.

A single wire (single hair) single wire brush hair 31a constituting the single wire brush hair row 32 is a single hair having a thickness of about 1 mm and a length of several tens of millimeters made of a resin such as polyacetal, and is made of rubber or the like. It is planted on the base material 35.

The high-density brush hair row is formed by arranging high-density brush hairs 31b in which a plurality of thin hairs are bundled along the axial direction of the brush portion 30. The two high-density brush bristles are spaced apart from each other in the circumferential direction of the brush portion 30. The two high-density brush hair rows are arranged so as to sandwich a plurality of single-wire brush hair rows 32 in the circumferential direction intersecting the axial direction of the brush portion 30.

The high-density brush hair 31b is specifically a unit of several to dozens of animal hairs such as pigs and wild boars. The animal hair is thinner and shorter than the single-line brush hair 31a. The animal hair is preferably one that hardly generates static electricity. Further, by bundling several animal hairs, it is possible to capture the hair 38 in the gap and generate appropriate friction. For this reason, when combing hair with the high-density brush bristles 31b, a larger tensile force can be applied to the hair 38 than when combing with the single-wire brush bristles 31a.

For example, when the hair care device 1 is moved at a speed of 100 mm / sec from the root side of the hair group to the hair tip side with respect to a hair group having a weight of 15 g and a length of 500 mm, the hair care device 1 is greater than 0.5N and 10 It is preferable that the tensile force acts on the hair group in a range smaller than 0.0N.

When the tensile force is 0.5 N or less, the hairs and swells of the hair 38 may not be sufficiently improved. On the other hand, if the tensile force is 10.0 N or more, the hair may come off or break.

A small range of tensile force can be applied to the hair 38 by combing the hair 38 with the single-line brush hair 31a. For example, in the single wire bristles 31a, a tensile force can be applied in a range larger than 0.5N and smaller than 3.0N, and it is preferable to apply a tensile force of about 1.5N.

A large range of tensile force can be applied to the hair 38 by combing the hair 38 with the high-density brush bristles 31b. For example, in the high-density brush bristles 31b, a tensile force can be applied in a range of 3.0N or more and smaller than 10.0N, and it is preferable to apply a tensile force of about 5.0N.

In addition to the animal hair, resin hair or the like can be used for the fine hair constituting the high-density brush hair 31b. In this case, it is preferable to use resin hair capable of forming appropriate gaps between the appropriate flexibility and the hair, and capable of capturing the hair 38 and generating appropriate friction.

The blower outlet 33 is provided in the base material 35, and the blower outlet 33a arranged in each between the adjacent single line | wire brush bristle rows 32, and the brush row | line | column of the high-density brush bristle 31b provided in the both ends outermost row of the circumferential direction And an outlet 33b provided on both side surfaces of the brush portion 30.

A hollow portion 36 is formed in the brush portion 30 in the direction of the single-line brush hair row 32, and air containing charged particles is supplied in the axial direction of the hollow portion 36 by the blower 3. In order to change the direction of the air flow toward the blower outlet 33a and the blower outlet 33b that open in the brush portion 30, a rectifying rib 37 is provided so as to intersect the airflow traveling direction. The rectifying ribs 37 are arranged in order from the windward side of the first ribs 37a, the second ribs 37b, and the third ribs 37c, and the protruding lengths downward in the order of the first ribs, the second ribs, and the third ribs become longer. ing.

The air supplied by the blower 3 advances toward the tip of the cavity 36 and is ejected in the radial direction of the brush part 30 from the blower outlet 33a and the blower outlet 33b, so that the volume gradually decreases as it approaches the tip. By adopting such a shape and arrangement of the rectifying rib 37, the collision surface of the airflow is gradually increased, and even if the volume of the airflow is reduced, the airflow can be efficiently ejected from the air outlet 33a and the air outlet 33b.

In the hair care device 1 having the above-described configuration, an operation description when performing hair styling will be described. When the user grips the grip portion 10 and operates the operation switches 18 and 19, the blower 3, the heater 4, and the charged particle generator 20 are driven. As a result, outside air flows into the air passage 24 through the suction port 15. The air flowing through the air passage 24 is heated by the heater 4 at the throttle unit 26 and flows into the ion mixing unit 27 through the inlet 26a.

The airflow that has flowed into the ion mixing unit 27 flows through the central portion of the ion mixing unit 27 at a high speed, and the ions generated from the discharge electrode 21 of the charged particle generator 20 are sucked and mixed by a negative pressure. A part of the air flow including ions passes through the connection port 16a and is partially sent out from the air outlet 34 between the bristles 31 in the axial direction.

Further, the air stream containing ions flows through the hollow portion 36 and is sent out from the gap between the single-wire brush bristles 31a in the radial direction by the blowout port 33a and simultaneously from the blowout port 33b in the side surface direction of the brush portion 30. When the user holds the grip portion 10 and moves it along the hair 38, the single-line brush hair 31a slides on the hair 38 and is brushed. At this time, the hair 38 is dried by the high-temperature air current sent out from the air outlet 33 and the air outlet 34, and the hair is adjusted by the single-line brush hair 31a.

In addition, since an air flow including ions is sent between the single-wire brush hairs 31a in parallel from the air outlet 33 and the air outlet 34, ions that reach and adhere to the hair 38 can be increased. The ions moisturize the hair 38 and static electricity generated in the hair 38 due to sliding with the single-wire brush hair 31a is removed. As a result, the hair 38 can be moisturized and the hair can be prevented from spreading due to static electricity, and good hair styling can be performed.

Referring to FIGS. 7 and 8, a hair care method using hair care device 1 according to the present embodiment will be described. Although not shown, it is assumed in both FIGS. 7 and 8 that there is a human head on the left side of the hair 38, and that the upper end of the hair 38 is on the head side and is connected to the human head.

The hair care method using the hair care device 1 according to the present embodiment includes a method for combing hair using the single-line brush hair 31a and a method for combing hair using the high-density brush hair 31b. including. It should be noted that the hair styling method using the single-wire brush hair 31a and the hair styling method using the high-density brush hair 31b can be switched.

FIG. 7 is a diagram illustrating an example of a hair care method using the hair care device of the present embodiment. As shown in FIG. 7, in the method of combing hair with the single-line brush hair 31 a, the single-line brush hair 31 a is inserted into the hair 38, and the hair care device 1 is moved from the root side to the tip side of the hair 38. Move to. As a result, the single-wire brush hair 31a is slid in contact with the hair 38. At this time, both hot air and positive and negative ions are ejected from the air outlet 33a of the brush portion 30 and sprayed onto the hair 38 and the single-line brush hair 31a.

Thus, positive static electricity charged to the hair 38 and negative static electricity charged to the single-wire brush hair 31a can be removed due to friction between the single-wire brush hair 31a and the hair 38. As a result, static electricity generated during brushing can be significantly suppressed, and hair damage due to static electricity can be suppressed.

In addition, the hair 38 is moisturized while the hair 38 is moistened by blowing warm air containing both positive and negative ions in a state where the hair 38 is captured by the single-line brush hair 31a and a tensile force is applied, and the hair 38 is moistened while being crushed and swollen. Can improve the hair quality. In addition, the gloss of the hair can be improved.

FIG. 8 is a diagram showing another example of a hair care method using the hair care device of the present embodiment. As shown in FIG. 8, in the method of combing the hair group with the high-density brush hair 31 b, the brush hair 31 is inserted into the hair 38 so that the high-density brush hair 31 b is inserted into the hair 38. . In this state, the hair care device 1 is moved from the root side of the hair 38 to the hair end side.

When switching the hair care method from the hair styling method using the single-wire brush hair 31a to the hair styling method using the high-density brush hair 31b, the user twists the hand holding the grip portion 10 at an appropriate position by about 90 degrees. The high-density brush bristles 31b rotate the brush portion 30 in the direction in which the hair 38 is captured. Thereby, the high-density brush hair 31b is inserted into the hair 38. In addition, only the hair-styling method using the high-density brush hair 31b may be implemented.

Here, since the high-density brush hair 31b is configured by bundling several animal hairs, the hair 38 can be captured by the hair 38 entering the gaps between the animal hairs. For this reason, the high-density brush bristles 31b are configured such that the friction with the hair is greater than that of the single-wire brush bristles 31a. Thus, by combing the hair 38 with the high-density brush bristles 31b, a larger tensile force can be applied to the hair 38 than when combing with the single-line brush bristles 31a.

Further, in the region 38a located on the rear side in the traveling direction of the high-density brush bristles 31b (the direction in which the hair is combed) as viewed from the high-density brush bristles 31b, the region 38a is located outside the high-density brush bristles 31b on the side surface of the brush portion 30. Hot air containing both positive and negative ions is blown from the outlet 33b located. Further, warm air containing both positive and negative ions is blown to the high-density brush bristles 31b from the air outlet 33a located inside the high-density brush bristles 31b.

Thus, the positive static electricity charged on the hair 38 and the negative static electricity charged on the high-density brush hair 31b, which are generated by friction between the high-density brush hair 31b and the hair 38, can be removed. As a result, static electricity generated during brushing can be significantly suppressed, and hair damage due to static electricity can be suppressed.

Further, by blowing warm air containing both positive and negative ions to the hair 38 in a state where a larger tensile force is applied than when only the single-wire brush hair 31a is used, the hair 38 is moisturized, and the hairs, swells, etc. Can effectively improve the hair quality. As a result, the gloss of the hair can be effectively improved.

Note that the blower 3 and the charged particle generator 20 can be driven with the heater 4 turned off by switching the operation switch 19. In this case, cold air containing positive and negative ions is sent out from the air outlet 34, so that the heat of the head is taken in a hot time and the hair 38 is moisturized by the ions to remove static electricity during hair styling. Can do.

Thus, the air flow sent out from the outlet 33 may be hot air or cold air. In this case, when the ambient temperature is 30 ° C., for example, the temperature of the air flow sent out from the outlet 33 is preferably 30 ° C. or more and 200 ° C. or less near the tip of the

bristles

31, and 50 ° C. or more. More preferably, it is 120 ° C. or lower.

When the temperature of the airflow is lower than 30 ° C. in the vicinity of the tip of the brush hair 31, the effect of improving the hair and swell due to heat becomes low. On the other hand, when the temperature of the airflow is higher than 120 ° C. in the vicinity of the tip of the brush bristles 31, there is a risk of damaging the hair even with a short blow. Further, when the temperature of the airflow is 50 ° C. or higher and 120 ° C. or lower in the vicinity of the tip of the brush hair 31, comb hair and swell can be further improved by a moderate heat effect.

As described above, according to the present embodiment, the air outlet 33 of the air passage 24 communicating with the grip portion 10 and the brush portion 30 opens between the brush hairs 31, and the discharge electrode 21 faces the air passage 24. The For this reason, the airflow which contains both positive and negative ions from the blower outlet 33 between the bristle 31 can be sent, and the ion which reaches | attains hair can be increased.

Further, since the discharge electrode 21 is disposed on the peripheral portion of the air passage 24 downstream from the throttle portion 26, it is possible to increase the number of ions that reach the hair while suppressing the disappearance of ions. Therefore, the hair 38 can be sufficiently moisturized and neutralized, and good hair styling can be performed.

In addition, the charged particle generator 20 is detachably attached to the grip portion 10, and the discharge electrode 21 is arranged facing the air passage 24 through an opening portion 27 b that opens to the peripheral surface of the air passage 24. Thereby, the charged particle generator 20 can be removed and the discharge electrode 21 can be easily cleaned, and the charged particle generator 20 in which the circuit board 50 and the discharge electrode 21 are integrated can be easily replaced. Further, since the discharge electrode 21 is disposed in the peripheral portion of the air passage 24, the charged particle generator 20 can be configured to be detachable with a simpler structure than that in the central portion.

Further, the cover 23 has a shielding rib 23 c that is close to the peripheral surface of the charged particle generator 20 and shields between the front part and the rear part of the charged particle generator 20. Thereby, the temperature rise of the circuit board 50 by the high temperature airflow which leaks from the clearance gap between the opening part 27b and the charged particle generator 20 can be prevented, and the reliability of the hair care apparatus 1 can be improved.

Further, a hollow portion 36 is formed on the same side as the discharge electrode 21 with respect to the axial center of the throttle portion 26, and the brush bristles 31 are disposed on the opposite side of the discharge electrode 21 with respect to the axial center of the throttle portion 26. As a result, ions generated at the discharge electrode 21 are smoothly guided to the cavity 36, and high-concentration ions can be sent out from the outlet 33.

Further, the single wire brush bristles 31 a are provided in a predetermined range excluding a part in the circumferential direction of the brush portion 30, and the air outlet 33 a is provided between the single wire brush bristles 32. Furthermore, the brush row | line | column of the high-density brush bristles 31b is distribute | arranged to the both ends of the circumferential direction of the brush part 30, and the blower outlet 33b is provided in the side surface of the brush part 30 on the outer side. Thereby, static electricity generated when the single-wire brush hair 31a and the high-density brush hair 31b are separated from the hair 38 can be efficiently eliminated.

Since the blower outlets 33a have a large number of rows and the total sum of the blower outlet areas, the balance between the two can be changed by making each opening area of the blower outlets 33a smaller than the opening area of the blower outlet 33b. By increasing the amount of the air flow from the blowout port 33b, the effect of contributing to the scalping of the hair 38 can be increased.

Also, instead of changing the opening area of the air outlet 33a or the air outlet 33b, the balance between the two can be changed by changing the number of air outlets.

In addition, since the outer peripheral surface of the reduced diameter portion 11 of the grip portion 10 is formed along the narrowed portion 26, the outer diameter of the reduced diameter portion 11 can be easily reduced, and the user can easily hold it. That is, the reduced diameter portion 11 is formed with a conical surface on the outer peripheral surface, and reduces the outer diameter of the grip portion 10 toward the operation portion 12 with respect to the suction port 15 side. For this reason, the user can grip the reduced diameter portion 11 having a small outer diameter adjacent to the operation portion 12.

Further, the charged particle generator 20 is arranged on the downstream side of the reduced diameter portion 11, and the operation switches 18 and 19 are provided in the operation unit 12 provided at a location where the volume is increased by storing the charged particle generator 20. Thereby, the movement operation of the hair care device 1 and the switching operation of the operation switches 18 and 19 during the hair styling operation can be easily performed.

Further, using the hair care method according to the present embodiment, the hair group in which the tensile force acts on the air flow including both positive and negative ions while acting the tensile force on the hair group, and the single-line brush hair 31a or the high-density brush hair By spraying on 31b and styling, hair damage can be suppressed and the hair quality can be improved.

Second Embodiment
Next, FIG. 9 is a perspective view of a hair care device according to a second embodiment of the present invention. FIG. 10 is a cross-sectional view in a direction perpendicular to the axis showing the internal structure of the brush portion of the hair care device of the present embodiment, and is a cross-sectional view of the brush portion 30 as viewed from the direction of the arrow BB in FIG. It is. For convenience of explanation, the same reference numerals are given to the same parts as those of the first embodiment shown in FIGS. In this embodiment, the bristle 31 is provided on the entire circumference of the brush part 30 in the circumferential direction. Other parts are the same as those in the first embodiment.

In the present embodiment, in the brush portion 30, single-line brush bristle rows 32 in which a plurality of brush hairs 31 are arranged in the axial direction are arranged in 24 rows at equal intervals over the entire circumference in the circumferential direction. Similar to the first embodiment, the brush bristles 31 include single-line bristles 31a made of a single line of synthetic resin, and high-density bristles 31b in which short animal hairs are bundled.

The high-density brush bristles 31b are arranged in rows at positions that divide the circumference of the brush portion 30 into three equal parts. That is, the high-density brush bristles are provided at positions that divide the circumference of the brush portion 30 into three equal parts. A plurality of single-line brush bristles 32 in which single-line brush bristles 31a are arranged are arranged in parallel between high-density brush bristles arranged at intervals in the circumferential direction.

Between the adjacent single-line brush bristle rows 32 and between the adjacent high-density brush bristle rows and single-line brush bristle rows 32, air outlets 33 composed of a large number of small holes are provided. In this embodiment, the blower outlet provided between the single line | wire brush hair row 32 is called the blower outlet 33a, and the blower outlet provided in the both sides of the high-density brush hair row in the circumferential direction of the brush part 30 is blower outlet 33b. Call.

In this embodiment, unlike the first embodiment, the hollow portion 36 provided in the brush portion 30 is formed concentrically with the connection port 16a and smaller in diameter than the connection port 16a. Since the diameter of the cavity portion 36 is smaller than that of the connection port 16 a, a gap is generated in the radial direction, and this gap constitutes the air outlet 34. Thereby, the airflow containing ions is sent out from the blower outlet 34 toward the brush hair 31 between the brush rows.

The air stream containing both positive and negative ions that have entered the hollow portion 36 is ejected in the radial direction from the air outlet 33 provided on the circumference of the brush portion 30. As a result, positive and negative ions adhere to the hair 38 and moisturize along with the hair styling of the hair 38, and static electricity generated by friction between the brush hair 31 and the hair 38 can be removed. By sending an air flow containing positive and negative ions from the

air outlets

33 and 34, many ions can reach the hair 38.

A rectifying rib 37 is provided inside the hollow portion 36 as in the first embodiment, but the rectifying rib, which has a substantially semicircular shape in the first embodiment, is a concentric circular shape that is structurally indispensable. Formed. The first rib 37a, the second rib 37b, and the third rib 37c are arranged in this order from the front as viewed from the connection port 16a, and the protruding length of the ribs is long in the order of the first rib 37a, the second rib 37b, and the third rib 37c. The formation is the same as in the first embodiment.

In the first embodiment and the second embodiment, the number of single-line brush bristle rows 32 and the number of high-density brush bristle rows and the area of the arrangement portion are different, but they are arranged with the same idea, and the same effect as the first embodiment is obtained. be able to. In addition, both positive and negative ions are discharged from the outlet 33b while capturing the head hair 38 and applying a tensile force by using at least one of the high-density brush hairs 31b arranged at three locations on the circumference of the brush portion 30 or the single-wire brush hair 31a. By spraying hot air containing the hair group on which the tensile force acts and the high-density brush hair row, hair damage can be suppressed and the hair quality can be improved.

Further, since ions are ejected from the air outlets 33 provided between the single-wire brush rows 32 and between the high-density brush rows and the single-wire brush rows 32, brushing is performed at any position in the circumferential direction of the brush portion 30. In addition, static electricity generated when the brush hair 31 is separated from the hair can be efficiently eliminated.

FIG. 11 is a diagram illustrating an example of a hair care method using the hair care device of the present embodiment. A hair care method according to the present embodiment will be described with reference to FIG. FIG. 11 shows an example of a hair styling method using high-density brush bristles 31b.

In the hair care method according to the present embodiment, the user inserts at least one of the high-density brush hairs 31b arranged at three locations on the peripheral surface of the brush portion 30 into the hair 38, and this In this state, the brush unit 30 is moved from the root side of the hair 38 to the hair tip side.

Specifically, the high-density brush bristles 31b and the single-line brush bristles 31a are captured while the hair 38 is captured by the high-density brush bristles 31b at the bottom of the brush portion 30 in the drawing and a tensile force is applied to the hair 38. Both are combing their hair 38.

Hot air containing both positive and negative ions is blown from the air outlet 33b on both sides of the high-density brush bristles 31b supplementing the hair 38 to the area 38a that is the peripheral area of the high-density brush bristles 31b. Thereby, it is possible to remove positive static electricity charged in the hair group and negative static electricity charged in the high-density brush hair 31b due to friction between the high-density brush hair 31b and the hair group. As a result, static electricity generated during brushing can be significantly suppressed, and hair damage due to static electricity can be suppressed.

Further, by blowing warm air containing both positive and negative ions on the hair 38 in a state where a tensile force is applied, the hair quality such as comb hair and swell can be effectively improved while moisturizing the hair 38. . As a result, the gloss of the hair can be effectively improved.

At the same time, as shown in the upper left in the figure, the brush portion 30 is positioned behind the high-density brush bristles 31b supplementing the hair group in the direction of travel (direction of combing the hair), and the other high-density brush bristles 31b Warm air containing both positive and negative ions is blown also to the region 38b located in the vicinity from the air outlet 33b on both sides of the other high-density brush bristles 31b.

Tensile force is also acting on the hair group located in the vicinity of the other high-density brush bristles 31b (located in the region 38b) by the high-density brush bristles 31b at the bottom of the brush portion 30 in the figure. For this reason, in the hair group located in the vicinity of the other high-density brush hairs 31b, the hair quality such as hair and swell can be improved while moisturizing the hair 38.

When the user slightly rotates the gripping portion 10 held counterclockwise in the figure, the other high-density brush hairs 31b on the upper left in the figure can also capture the hair 38, so that the tensile force is further increased. Can be hung. Even in this case, for the same reason as described above, static electricity generated during brushing can be significantly suppressed, and hair damage due to static electricity can be suppressed. In addition, the hair quality such as comb hair and swell can be effectively improved while moisturizing the hair 38.

Thus, since the hair quality can be improved while suppressing damage to the hair at a plurality of locations, the hair styling time can also be shortened. In addition, since the hair 38 is combed using the high-density brush bristles 31b while using the single wire bristles 31a, the hair quality such as comb hair and swell can be improved more effectively in this respect, Hair styling time can be shortened.

<Third Embodiment>
In the second embodiment, the high-density brush bristles 31b are arranged in rows at positions that divide the entire circumference of the brush portion 30 into three equal parts, but may be arranged at positions that divide the entire circumference into two equal parts. It may be arranged at a position that divides up to 6 equal parts.

In this case, the hairs and swells can be further improved by supplementing the hair with more high-density brush hair rows as compared with the first embodiment. In addition, the hair styling time can be shortened.

However, if the number of rows of high-density brush hairs increases, friction is increased during hair styling, which not only increases the burden on the user's arm, but can also hurt the hair. It is preferable that the number of rows and the number of rows are appropriately arranged depending on the material and the planting density of the high-density brush bristles 31b.

Since the main user of a hair care device such as the present invention is considered to be a woman, it is necessary to consider the burden on the arm due to weak arm strength and wrist strength and the burden on the neck due to long hair, It is important that there are few and easy to handle.

<Fourth embodiment>
In the first to third embodiments, the high-density brush bristles 31b are arranged in one row at each position, but may be in a plurality of rows. In this case, too much installation increases friction during hair styling, which not only increases the burden on the user's arm strength and physical strength, but also hurts the head hair. Appropriate placement should be sought depending on the planting density. In this case, it is possible to further improve comb hair and swell as compared with the first embodiment. In addition, the hair styling time can be shortened.

<Fifth Embodiment>
In the above embodiment, the hair care apparatus 1 may be a hair dryer that omits the heater 4 and sends out cold air. In the case where hot air is not used, the wrinkle is gently removed by moistening with ions. Even in this case, static electricity generated by friction between the high-density brush hair 31b and the hair group can be removed by both positive and negative ions. For this reason, also in 5th Embodiment, the substantially equivalent effect as 1st Embodiment is acquired.

<Sixth Embodiment>
The charged particle generator 20 used in the present invention generates air ions, but is not limited thereto. For example, the charged particle generator 20 may be configured by an electrostatic atomizer. In the electrostatic atomizer, condensed water is generated on the surface of the discharge electrode 21 by cooling the discharge electrode 21 with a Peltier element. When a negative high voltage is applied to the discharge electrode 21, charged fine particle water containing negative ions is generated from the dew condensation water. Further, when a positive high voltage is applied to the discharge electrode 21, charged fine particle water containing positive ions is generated from the dew condensation water. As a result, positive and negative charged particles made of charged fine particle water can be sent to moisturize and neutralize the hair.

For this reason, even in the hair care method according to the present embodiment, substantially the same effect as the hair care method according to the first embodiment can be obtained.

Further, by disposing the discharge electrode 21 on the peripheral portion of the air passage 24 and providing the throttle portion 26 on the upstream side, the charged fine particle water disappears due to evaporation of the charged fine particle water by direct contact of the air flow with the charged fine particle water. Can be prevented.

(Verification experiment 1)
FIG. 12 is a diagram showing the conditions and results of verification experiment 1 performed to verify the effects of the present invention. FIG. 13 is a diagram showing numerical results of the verification experiment 1 shown in FIG. With reference to FIG. 12 and FIG. 13, the verification experiment 1 performed in order to verify the effect of this invention is demonstrated.

As shown in FIG. 12 and FIG. 13, in the verification experiment 1, the gloss of the hair when hair was set using the hair care method in Examples 1 and 2 and Comparative Examples 1 to 3 was evaluated. As a hair care method in Example 1, warm air containing both positive and negative ions was blown to the hair group while whisking the hair group with the high-density brush bristles 31b. As a hair care method in Example 2, warm air containing both positive and negative ions was blown to the hair group while whisking the hair group with the single-line brush hair 31a.

As a hair care method in Comparative Example 1, warm hair that does not contain both positive and negative ions was blown while the hair was combed with the high-density brush bristles 31b. As a hair care method in Comparative Example 2, warm air that does not contain both positive and negative ions was blown to the hair group while whispering the hair group with the single-line brush hair 31a. As a hair care method in Comparative Example 3, warm air containing only negative ions was blown to the hair group while combing the hair group with the single-line brush hair 31a.

When evaluating the gloss of the hair, the state before and after the blow by the hair care device was photographed from the top of the head to the back of the head using a camera in a dark room. The camera used was EOS Kiss X5 (Canon). Blowing was performed three times for each block with the top and back of the head divided into 6 blocks.

As shown in FIG. 12, in the image shown in Example 1, compared to Comparative Examples 1 to 3, there are straight annular bright portions (so-called angelic rings) that shine by reflecting light. . Thereby, when the hair care method in Example 1 is implemented, it can be confirmed that the most beautiful gloss is obtained.

Further, the gloss value was calculated from an image taken using image processing software (product name: “Photoshop (registered trademark)”, Adobe System Inc).

The gloss value was calculated by the average luminance of the portion with the highest luminance (annular bright portion that looks like an angel's ring in FIG. 12) / average luminance of the dark portion. Here, the dark portion is a portion that is located around a circular bright portion that looks like an angel's ring in FIG. 12 and that is a predetermined distance downward from the bright portion.

The gloss value (initial value) in the initial state before blowing is compared with the gloss value in the state after blowing, and the relative value when the initial value is 100 in each of Examples 1 and 2 and Comparative Examples 1 to 3 is Calculated. FIG. 13 shows the relationship between Examples 1 and 2 and Comparative Examples 1 to 3 and relative values.

As shown in FIG. 13, in Example 1, when the initial value is 100, the relative value after blow is 143, and the gloss value is increased by 43%. On the other hand, in Comparative Example 1 and Example 2, the relative values after blowing are 122 and 113, and it can be confirmed that the gloss value is improved although it does not reach Example 1. In Comparative Examples 2 and 3, the relative values after blowing were both 105, and there was almost no change in the gloss value.

The results of Examples 1 and 2 are compared with the results of Comparative Examples 2 and 3, and it can be confirmed that the gloss is improved by spraying both positive and negative ions on the hair group. Moreover, while comparing the result of Example 1 with the result of Example 2, and the result of Comparative Example 1 with the result of Comparative Example 2, while applying a tensile force to the hair group using the high-density brush hair 31b, It can be confirmed that the gloss is further improved by combing the hair group.

Furthermore, by comparing the result of Example 1 with the result of Comparative Example 2 and spraying both positive and negative ions while applying a tensile force to the hair group using the high-density brush hair 31b, the gloss value is greatly reduced. It can be confirmed that it can be improved.

(Verification experiment 2)
FIG. 14 is a diagram showing conditions and results of a verification experiment 2 performed to verify the effect of the present invention. With reference to FIG. 14, the verification experiment 2 performed in order to verify the effect of this invention is demonstrated.

As shown in FIG. 14, in the verification experiment 2, the potential difference between the hair group and the brush unit 30 when the hair was shaped using the hair care method in Example 1, Comparative Example 1, and Comparative Example 3 was measured. The hair care method in Example 1 and Comparative Examples 1 and 3 is the same method as the hair care method in Verification Experiment 1.

In the measurement of the potential difference, the charge amount of the hair group and the brush after blowing was measured with a surface potentiometer FMX-003 (manufactured by Simco), and the potential difference between the two was compared. The charge amount was measured three times for each test hair group described later, and an average value was calculated. The friction between the high-density brush bristles 31b and the hair group charges the hair group side to positive polarity, and the brush side charges to negative polarity.

When preparing the hair group to be blown, the hair group of 15 g was used as a test hair group. A predetermined number of these test hair groups were prepared, and the average value of the potential difference in each test hair group was calculated.

In Example 1 and Comparative Example 1, the blowing was performed by supplementing the hair group with the high-density brush bristles 31b and moving the brush part 30 from one end side to the other end side of the hair group. Further, the amount of charge was measured after blowing five times. In Comparative Example 3, the blowing was performed by inserting the single-line brush hair 31a into the hair group and moving the brush portion 30 from one end side to the other end side of the hair group. Further, the amount of charge was measured after blowing five times.

The potential difference in Example 1 is sufficiently smaller than the potential difference in Comparative Example 1 and Comparative Example 3. The potential difference in Comparative Example 1 was almost the same value as the potential difference in Comparative Example 3.

From these results, in Example 1, positive static electricity charged on the hair group side and negative polarity charged on the brush portion side by blowing warm air containing both positive and negative ions to the hair group on which the tensile force acts. Thus, it can be said that the potential difference can be reduced.

On the other hand, comparing the result of Comparative Example 1 with the result of Comparative Example 3, the following is considered. By spraying negative ions onto the hair group, positive static electricity charged on the hair group side can be removed, but negative static electricity charged on the brush portion 30 side cannot be removed. For this reason, it is considered that the hair group is scooped by the brush portion 30 that is negatively charged, the generation of static electricity cannot be suppressed, and the potential difference between the brush portion 30 side and the hair group side cannot be improved.

(Verification experiment 3)
FIG. 15 is a diagram showing conditions and results of a verification experiment 3 performed to verify the effect of the present invention. With reference to FIG. 15, a verification experiment 3 performed to verify the effect of the present invention will be described.

As shown in FIG. 15, in the verification experiment 3, the number of split ends and cut hairs in the hair group after hair styling using the hair care method in Example 1, Comparative Example 1 and Comparative Example 3 was measured. The hair care methods in Example 1 and Comparative Examples 1 and 3 are the same as the hair care methods in Verification Experiment 2.

When preparing the hair group to be blown, the black hair was bundled by dividing it into 5 g (1500 pieces) and then trimmed to a length of 40 cm to create a hair bundle. This hair bundle was trimmed to 30 cm with hair scissors to remove split ends and cut hairs to obtain a test hair group.

In Example 1 and Comparative Example 1, the blowing was performed by supplementing the hair group with the high-density brush bristles 31b and moving the brush part 30 from one end side to the other end side of the hair group. After repeating this 300 times continuously, the number of split ends and cut hairs was measured in the hair group. In Comparative Example 3, the hair group was combed 300 times using the single-line brush hair 31a.

In Example 1, the number of split ends and cut hairs was smaller than in Comparative Examples 1 and 3. Thereby, using the hair care method in Example 1, hair damage is caused by blowing warm air containing both positive and negative ions to the hair group on which the tensile force acts while applying the tensile force to the hair group, and then adjusting the hair. It was confirmed that it can be suppressed.

Further, from the result of Comparative Example 1, it was confirmed that hair damage could not be sufficiently suppressed when hot air containing both positive and negative ions was not blown. Furthermore, from the results of Comparative Example 3, it was confirmed that hair damage could not be sufficiently suppressed even when only negative ions were sprayed onto the hair group.

By spraying negative ions onto the hair group, positive static electricity charged on the hair group side can be removed. However, since the negative static electricity charged on the brush portion 30 side cannot be removed, the potential difference between the brush portion 30 side and the hair group side cannot be improved. As a result, it is considered that static electricity due to friction between the high-density brush bristles 31b and the hair group could not be suppressed, and the hair was easily damaged.

(Verification experiment 4)
FIG. 16 is a diagram showing conditions and results of a verification experiment 4 performed to verify the effect of the present invention. With reference to FIG. 16, the verification experiment 4 performed in order to verify the effect of this invention is demonstrated.

As shown in FIG. 16, in the verification experiment 4, the surface state of the hair group after styling using the hair care method in Example 1, Comparative Example 1 and Comparative Example 3 was observed. The hair care methods in Example 1 and Comparative Examples 1 and 3 are the same as the hair care methods in Verification Experiment 3.

Further, the same hair group as in the verification experiment 3 was used as a test hair group, and the hair was blown continuously 300 times under the same conditions. The hair contained in the hair group after repeatedly blowing 300 times continuously was observed with an ultra-deep multi-angle lens microscope VHX-500 (manufactured by Keyence Corporation). During the observation, the hair was ligated at a position of about 15 cm, which is the center, and the vicinity of the knot was observed.

In Example 1, almost no peeling or lifting of the cuticle was observed. On the other hand, in Comparative Examples 1 and 3, peeling and lifting of the cuticle were observed, and the hair was damaged.

Also from such a result, using the hair care method in Example 1, hot air containing both positive and negative ions is blown to the hair group on which the tensile force acts and the high-density brush hair 31b while applying the tensile force to the hair group. It can be said that it was confirmed that hair damage can be suppressed by styling the hair.

(Verification experiment 5)
FIG. 17 is a diagram showing conditions and results of a verification experiment 5 performed to verify the effect of the present invention. With reference to FIG. 17, the verification experiment 5 performed in order to verify the effect of this invention is demonstrated.

As shown in FIG. 17, in the verification experiment 5, the rate of change in the length of the hair before and after hair styling was evaluated when hair styling was performed using the hair care method in Examples 1 and 2 and Comparative Examples 1 to 3. The hair care methods in Examples 1 and 2 and Comparative Examples 1 to 3 are the same as the hair care method in Verification Experiment 1.

In the evaluation of the rate of change in hair length, hair groups having comb hairs and undulations were prepared, and the length of the hair group before blowing and the length of the hair group after blowing were measured.

When preparing hair groups having comb hairs and undulations, first, hair groups having a total weight of 15 g were prepared. Next, this hair group was immersed in water for 5 minutes or more and wound around a test tube having a diameter of 24 mm. In this state, the hair group was naturally dried for 24 hours or more and allowed to stand. By removing the hair group from the test tube, a hair group having comb hairs and undulations was prepared.

In measuring the rate of change, first, the length of the hair group in a state removed from the test tube was measured as the length of the hair group before blowing. In this case, the length before blowing was about 20 cm to 23 cm. Subsequently, when the high-density brush hair 31b is used, the hair group is captured by the high-density brush hair 31b. When the single-wire brush hair 31a is used, the single-wire brush hair 31a is inserted into the hair group, and the brush portion Blowing was performed by moving 30 from one end side of the hair group to the other end side. Blowing was performed 5 times.

The length of the hair group after 5 blows (after the blow treatment) was measured and compared with the length of the hair group before blowing. At this time, a value obtained by dividing the difference between the length of the hair group after the blow treatment and the length of the hair group before the blow treatment by the length of the hair group before the blow treatment was defined as the rate of change.

In Example 1, the rate of change was the largest, and the hair and swell could be improved most. In Example 2, the rate of change was larger than that in Example 1, and it was possible to improve comb hair and swell.

In Example 2, the rate of change is larger than in Comparative Example 2. By comparing the results of Example 2 and the results of Comparative Example 2 and blowing warm air containing both positive and negative ions to the hair group, it can be confirmed that the hair / undulation is improved.

Further, the change rate of Comparative Example 1 is slightly larger than that of Comparative Example 2. Comparing the results of Comparative Example 1 with the results of Comparative Example 2, it can be confirmed that the hair group is supplemented with the high-density brush hair 31b and a tensile force is applied to the hair group to improve the hair and swell. .

Thus, each of blowing hot air containing both positive and negative ions to the hair group and applying a tensile force to the hair group contributes to the improvement of comb hair and swell. For this reason, when the hair care method in Examples 1 and 2 including both of these operations was used, the rate of change increased as described above, and it was possible to improve comb hair and swell. Furthermore, by using the high-density brush bristles 31b and applying a greater tensile force to the hair group than the single-line brush bristles 31a, the hairs and swells could be improved.

As described above, it can be said from the results of the verification experiments 1 to 5 that it was confirmed that the hair damage can be suppressed and the hair quality can be improved by using the hair care method according to the present embodiment.
