  Many women have various problems regarding beauty, and one typical example is the problem of hair damage. Hair damage is mainly caused by hair drying. Drying of the hair not only causes a feeling of rustling, but also causes problems such as easy generation of static electricity, loss of cohesion of the entire hair, and easy attachment of dust and dust.

Cosmetics such as hair conditioners have been sold for a long time as a means of hair care. The basic function of these cosmetics is to smooth the surface of the hair. By doing so, the frictional force between the hairs is reduced and the hair is felt soft, the light reflection efficiency is improved, and gloss (gloss) is obtained on the hair.
The hair conditioner has a cationic surfactant as a main component. This is because the cationic surfactant is easily adsorbed to negatively charged hair. Using this property, the hair is covered with a surfactant to smooth the surface.
The method of using cosmetics as described above has a problem that the effect is temporary, such as not being sustained in a dry environment, in addition to the troublesome treatment.

On the other hand, in recent years, beauty equipment that allows easy hair care at home has been commercialized. For example, Patent Documents 1 and 2 disclose and commercialize beauty devices such as hair dryers and hair irons that generate ions. These devices are said to improve the hair condition by negatively charged ions. However, in the case of wet or damaged hair, since it is negatively charged, even if negative ions are generated, the adsorption efficiency to the hair is low.
On the other hand, in the case of dry hair, especially when it is dried while brushing, the hair is positively charged due to friction between the hair and the brush. Get higher.

  Patent Document 3 discloses a hair dryer that generates both positive ions and negative ions. Similar to those disclosed in Patent Documents 1 and 2, the hair dryer eliminates the charging phenomenon of hair. It is intended to improve the hurt.

(Embodiment 1)
FIG. 1 is a perspective view showing an appearance of a beauty device as an embodiment of a hair humidification and damage reduction method and hair humidification and damage reduction device according to the present invention. FIG. 2 is an internal configuration of the beauty device. FIG.
This beauty device has a substantially cylindrical shape in which an air flow path 3 is formed. A discharge port 1 for discharging air is formed on the downstream side of the air flow path 3, and air is provided on the upstream side. Is formed. The air flow path 3 is a flow path from the suction port 2 to the discharge port 1. In the air flow path 3, a sirocco fan and a blower mechanism 4 having a motor for driving the sirocco fan are provided. The suction port is the suction port 2.

The air blowing mechanism 4 sucks air from the suction port 2 and introduces it into the air flow path 3, and allows air to flow downstream of the air flow path 3. A heating section 5 for heating the air flowing through the air flow path 3 is provided in a portion of the air flow path 3 on the downstream side of the air blowing mechanism 4. The heating unit 5 includes an insulating plate and a heater wire wound around the outside of the insulating plate.
In addition, two branch channels 3 a and 3 b are branched from a portion of the air channel 3 downstream of the air blowing mechanism 4 and upstream of the heating unit 5. The branch channels 3a and 3b are formed inside cylindrical projecting cylinders 7a and 7b that are continuously provided outward from the side surface of the air channel 3, and the air channels 3 of the main body at the inlets of the branch channels 3a and 3b. Communicated with.

In the two branch channels 3a and 3b, there are respectively provided ion generators 10a and 10b for generating positive ions and negative ions, respectively. The positive ions and negative ions generated by the ion generators 10a and 10b are individually Sent to the hair along with the wind.
A handle 21 is provided on the suction passage 2 side of the air flow path 3 in a direction substantially perpendicular to the longitudinal direction of the air flow path 3, and an operation switch 6 is provided at a portion gripped by the user of the handle 21. Inside the handle 21 is housed a body case 14 of an ion generator including the ion generators 10a and 10b.

FIG. 3 is a perspective view showing an example of the external appearance of the ion generator 10.
The ion generator 10 includes a main body case 14 that houses the circuit portion, and an ion generator 10a.
, 10b. The ion generators 10a and 10b have a substantially hemispherical shape, and ion discharge holes 14a and 14b formed in, for example, a circular shape with a diameter of about 8 mm are opened in the flat part of the hemisphere, and the top of the hemisphere has a high pressure. It is connected to the main body case 14 by an electric wire.
At substantially the center in the discharge holes 14a and 14b, needle-shaped discharge electrodes 11a and 11b are arranged in such a manner as to penetrate the discharge hole surface in a perpendicular direction. Further, around the discharge electrodes 11a and 11b, annular counter electrodes 12a and 12b are arranged to face each other along the discharge holes 14a and 14b.

FIG. 4 is a circuit diagram illustrating a configuration example of the ion generator 10.
In the ion generator 10, the counter electrodes 12 a and 12 b and the discharge electrodes 11 a and 11 b are connected to a high-voltage power supply unit 13 housed in a main body case 14.
The high-voltage power supply unit 13 is connected to the AC100V power supply 15 through an outlet, the anode of the diode D1 is connected to one plug of the outlet, the cathode of the diode D1 is connected to one terminal of the capacitor C1 through the resistor R1, and The anode of the two-terminal thyristor D2 is connected. The other terminal of the capacitor C1 is connected to the other plug of the outlet, and a primary coil of the transformer 16 is connected between the cathode of the two-terminal thyristor D2 and the other plug of the outlet.

One terminal of the secondary coil of the transformer 16 is connected to the cathode of the diode D3 of the ion generator 10a, and the anode of the diode D3 is connected to the discharge electrode 11a. One terminal of the secondary coil of the transformer 16 is also connected to the anode of the diode D4 of the ion generator 10b, and the cathode of the diode D4 is connected to the discharge electrode 11b.
The other terminal of the secondary coil of the transformer 16 is connected to the counter electrodes 12a and 12b.

The high-voltage power supply unit 13 connected to the one discharge electrode 11a generates a negative high-voltage pulse voltage (for example, a frequency of 60 Hz and a peak voltage of about −2 kV). The high-voltage power supply unit 13 connected to the other discharge electrode 11b generates a positive high-voltage pulse voltage (for example, a frequency of 60 Hz and a peak voltage of about 2 kV). As a result, discharge occurs between the distal ends of the discharge electrodes 11a and 11b and the counter electrodes 12a and 12b, and plasma is generated. Molecules such as oxygen (O ²⁻ ) and water (H ₂ O) in the air receive energy by the generated plasma.

When the voltage applied to the discharge electrode is a positive voltage, water molecules in the air are ionized to generate hydrogen ions (H ⁺ ). The hydrogen ions are clustered with water molecules in the air (grouped together), and positive ions composed mainly of H ⁺ (H ₂ O) m (m is an arbitrary natural number) are mainly generated. Then, positive ions are discharged from the discharge hole 14b provided with the discharge electrode 11b.

When the voltage applied to the discharge electrode is a negative voltage, oxygen molecules or water molecules in the air are ionized to generate oxygen ions O ²⁻ . The oxygen ions are clustered with water molecules in the air, and negative ions composed mainly of O ²⁻ (H ₂ O) n (n is an arbitrary natural number) are mainly generated. Then, negative ions are released from the discharge hole 14a provided with the discharge electrode 11a.

In the first embodiment, the positive ion generation unit and the negative ion generation unit are arranged so as to be opposite to each other with respect to the air flow path 3 and the air outlet 1. The negative ion generation part is not limited to the ions generated by each of the negative polarity ions being combined and extinguished. You may be closer to each other.
According to the inventors' confirmation, if the positive ion generation part and the negative ion generation part are separated by about 20 mm in a direction perpendicular to the air flow sending direction, the effect of ions is exhibited.

  Furthermore, even if the positive ion generation part and the negative ion generation part are brought closer to each other and arranged so as to be in contact with each other, it is inevitable that a part of the ions disappear due to the coupling, but only the ion delivery amount decreases, The effect itself is not lost. The positive ion generation unit and the negative ion generation unit are preferably arranged so that positive ions and negative ions are carried by the airflow sent from the outlet 1.

Below, operation | movement of the beauty apparatus of such a structure is demonstrated.
In this beauty device, when the operation switch 6 is turned on, the blower mechanism 4 and the ion generator 10 are activated. At this time, the air blowing mechanism 4 blows air at a wind speed of 15 m / s or less at the position of the object.
The air blowing mechanism 4 sends out air sucked from the suction port 2 from the discharge port 1. During the “drying operation” in which hot air used for drying hair is generated, the heating unit 5 operates.
In addition, negative ions and positive ions are released individually from the ion generators 10a and 10b, respectively. The generated ions are released forward by the air that has flowed in through the branch flow paths 3a and 3b, and are radiated to the user's hair by riding on the airflow sent from the discharge port 1.

The cosmetic device according to the first embodiment is configured such that a moisturizing operation and a drying operation can be selected, and the air blowing mechanism 4 and the ion generator 10 are operated during the moisturizing operation. Further, during the drying operation, the air blowing mechanism 4 and the heating unit 5 are operated.
The water generated by the combination of positive ions H ⁺ (H ₂ O) m and negative ions O ²⁻ (H ₂ O) n and the water clustered into both ions are different from generally recognized water, It is considered that the amount of water is directly increased by penetrating into the inside regardless of the surface structure of the hair because of the molecular level.

In general, various types of ions can be generated in an ion generator by discharge. However, considering the effect on hair, it is preferable that the generation of nitrogen oxides be small.
Also, water generated by ion reaction and adsorbed on hair, or water adsorbed on hair after clustering into ions is activated by molecular movement due to heating, and diffusion into the air occurs. It is preferable that the heating unit 5 is not activated.
On the contrary, during the drying operation, the generated both ions simply act as charges, so that ions having a polarity opposite to the charge of the hair are mainly adsorbed to the hair to eliminate the charge. Generally, since hair is easily charged to the positive electrode, the sent negative ions are adsorbed to the hair and the positive ions are repelled.

As described above, a moisturizing effect is not expected during the drying operation, but since a static elimination effect is obtained, it is preferable that the ion generator 10 be configured to always operate.
Accordingly, the “drying operation” mode is provided to operate the air blowing mechanism 4, the heating unit 5, and the ion generating device, and the “moisturizing operation” mode is provided to operate only the air blowing mechanism 4 and the ion generating device 10. This will improve convenience for the user.

  In addition, it is possible that the user can select everything instead of automatic driving. The air volume of the blower mechanism 4 can be selected from “strong”, “weak”, and “stop”, and “operation” and “stop” of the ion generator 10 and “operation” and “stop” of the heating unit 5 can be selected. Preferably it is configured. In general, the operation switch 6 is a multi-circuit switch, or a switch that is turned on / off for each functional unit is provided separately.

(Embodiment 2)
Since the charging of the hair changes depending on the season and the quality of the hair, in addition to the first embodiment, the ion generator 10 is preferably configured to allow the user to change the ion generation amount.
Similarly, it is more convenient for the user to change the air flow rate of the air blowing mechanism 4, but in this case as well, the ion concentration can be maintained even if the air flow rate is large. It is preferable to increase the ion generation amount of the generator 10.

  In general, the amount of ions generated by the ion generator 10 naturally increases as the amount of air passing through the ion generators 10a and 10b increases without changing the voltage applied to the discharge electrodes 11a and 11b. . However, since the ion concentration is not always expected, it is preferable to change the pulse applied to the discharge electrodes 11a and 11b.

FIG. 7 is a circuit diagram showing a configuration example of an ion generator of a beauty device according to the second embodiment of the present invention.
This ion generator 10c is an example in which a switching element that conducts under computer control is added to the configuration of the ion generator 10 shown in FIG.

This switching element is an NPN transistor TR, the base is connected to the output terminal of the microcomputer through the resistor R3, and the collector is connected to the cathode of the light emitting diode D5 of the photocoupler 17 through the resistor R2. A resistor R4 is connected between the base and emitter of the transistor TR, and the negative pole of a 12V battery 19 is connected to the emitter. The positive electrode of the battery 19 is connected to the anode of the light emitting diode D5.
The light receiving side (output side) of the photocoupler 17 is a photo bidirectional diode T, and the photo bidirectional diode T is connected between the other terminal of the AC 100V power source and the other terminal of the capacitor C1.

It is also possible to incorporate the switching element TR into the main body circuit of the ion generator 10c. The switching element TR is housed in the main body of the ion generator 10c, and a pulse applied to the ion generators 10a and 10b by turning on / off the power supplied to the ion generator 10c at an arbitrary timing by a microcomputer. The number of can be changed.
In general, when the number of pulses increases, the amount of ion generation increases, and when the number of pulses decreases, the amount of ion generation decreases. In order to improve the convenience of the user, the body of the beauty device is provided with a means to specify the ion increase and decrease in a uniform manner, that is, the “increase / decrease” switch, “increase” button, “decrease” button, etc. It is common to leave.

In addition, a perforated disk-shaped partition plate 205 that partitions between the blower 202 and the heating device 203 forms a space 206 into which the user's head is placed. Each opening 207 is provided with a humidifying part 208 having a water retaining function sponge or the like for humidifying the sucked air.

Is provided. The positive ion generator 204a and the negative ion generator 204b are needle-like discharge electrodes, respectively, and ions are generated by applying a high voltage between the induction electrode 204c.

In the commercial hair dryer 20, the required functions are not particularly different from those in the first and second embodiments, and the “hot air drying mode” in which the hair is dried by heating the air and the air is heated. It is equipped with a “cold-air drying mode” that dries hair without using it.
As in the cases of the first and second embodiments, the “warm air drying mode” is expected to make it easier to bundle hair by removing the charge of the hair.
Accordingly, even in the “warm air drying mode”, the blower 202, the heating device 203, and the ion generation device 204 operate.

In the “cold air drying mode”, an effect of supplying moisture to hair and improving hair quality is expected, and the blower 202 and the ion generator 204 are activated.
Further, in order to adjust drying conditions that vary depending on the season and hair quality, it is preferable to provide ion amount adjusting means for changing the amount of ions, as in the cases of the first and second embodiments.

The treated hair bundles were observed, and the generated split ends and cut hairs were counted.

FIG. 11 shows the result of counting the damaged hair generated in the hair sample in this way. The graph shown in FIG. 11 represents the number of split ends and broken hairs generated in the hair applied with air containing positive and negative ions and the hair applied with air containing only ions.
According to this graph, the hair irradiated with positive and negative ions had about 1/2 the number of split ends and broken hairs compared with the hair applied with only air not containing ions. As a result, damage to the hair irradiated with ions was suppressed as compared with the hair not irradiated with ions.
The above results show that the hair humidification and damage reduction method according to the present invention provides moisture to the hair and improves the strength of the hair, as well as generating both positive and negative ions. This is the result that both the brushes to be removed can be neutralized, and the friction during brushing can be reduced.

  The hair humidification and damage reduction method and the hair humidification and damage reduction apparatus according to the present invention are applied to a commercial hair dryer used in a hand dryer, a beauty salon, etc., thereby using drugs and steam. Therefore, it is possible to safely and easily perform moisturizing care of hair and reduce injuries during brushing.
