Description

  The present invention relates to an electric hair comb, and more particularly, to an electric hair comb used for a treatment that allows a drug to penetrate into hair, such as hair treatment, pretreatment, perm, and color.

  In general, hair is often damaged externally or internally by applying permanents, coloring, or external stimuli such as the heat of a dryer or ultraviolet rays. In such a case, it is known that the hair is repaired and improved by treating the hair. This treatment involves repairing and improving the exterior of the hair (specifically, attaching silicon or PPT (a protein that is said to be close to hair components) to the surface of the hair) and repairing the interior of the hair. However, in the case of the former method, it can be roughly divided by external stimuli such as a dryer or shampoo. The latter method is preferable because the substance adhering to the hair easily peels off and there is a possibility that the weak hair tissue may peel off together. When the treatment solution is to penetrate into the hair using this latter method, first wet the hair by shampooing it, open the hair epidermis (cuticle) covering the hair, and then attach the treatment solution to the hair. Usually, combing is performed using a comb and the treatment liquid is applied to the hair.

By the way, in this treatment, the moisture inside the hair is fully saturated when the hair is wet and the hair epidermis is opened, and the moisture that has penetrated into the hair with a comb from this state Since the treatment liquid penetrates into the hair while discharging the hair, this combing technique requires a high level of skill, and a considerable skill (skill level) is also required for a beauty technician such as a hairdresser. For this reason, the development of a combing instrument that can alleviate this technique has been awaited in the past. Recently, this type of instrument has been proposed as a treatment apparatus and disclosed in Patent Document 1. The treatment device described in Document 1 includes an apparatus main body having an operation mechanism unit and a comb unit. The operation mechanism unit includes a power supply unit, a motor, a gear, a gear, a cam unit, a rod, and a shaft unit. Is configured to reciprocate in the longitudinal direction of the comb portion. In this case, one pitch of the comb teeth of the comb portion is selected from a range of 1.5 mm to 2.5 mm, and the amplitude of the comb portion is set to 2.0 mm to 8.0 mm, preferably 4.0 mm. Is set to a range of 1000 to 5000 times per second. In this way, the comb portion is reciprocated to vibrate the hair from the comb portion.
JP 2006-304988 A

  However, in the conventional treatment apparatus, as described above, the amplitude of the reciprocating motion of the comb portion is set to 2.0 mm to 8.0 mm, preferably 4.0 mm, and the number of vibrations of the reciprocating motion is set to 1000 to 5000 times / second. The comb part is reciprocated, but the comb part movement by the combination of the amplitude and the number of amplitudes in this range causes the treatment liquid to penetrate into the hair, but the vibration at this time is excessive pressure against the hair. There is a problem that the hair is damaged (externally or internally). In addition, this treatment apparatus has the same problems even when applied to various treatments for penetrating a drug into hair such as pretreatment, perm, color, etc. in addition to treatment for hair treatment.

  The present invention solves such a conventional problem, and damages the hair externally or internally in various treatments for penetrating the drug into the hair, such as hair treatment, pretreatment, perm, and color. The object is to provide an electric hair comb that can sufficiently penetrate the inside of the hair.

  In order to achieve the above object, the present inventor has eagerly studied the relationship between the comb tooth pitch of the comb and the amplitude and the number of vibrations when the comb is reciprocated. Even in various treatments that penetrate the hair into the hair, such as perms, collars, etc., the movement of the comb that is necessary to penetrate the hair sufficiently into the hair and that does not damage the hair externally or internally The present invention has been found and has led to the creation of the present invention. The electric hair comb of the present invention comprises a comb having a plurality of comb teeth and a grip, and one end of the comb is attached to the grip end, and is operatively connected to an electric drive mechanism built in the grip. In the electric hair comb in which the comb is reciprocated in the arrangement direction of the comb teeth, a predetermined length suitable for combing hair to one pitch of the comb teeth of the comb is selected, and the amplitude of the comb reciprocation is set. The gist is that the number of reciprocating motions is set in a range of 40 to 50 times per second for one pitch of substantially comb teeth.

  The electric hair comb of the present invention has the above-described configuration, by reciprocating the comb portion with the amplitude of the reciprocating motion of the comb being approximately one pitch of the comb teeth and the frequency of reciprocating vibration of 40 to 50 times / second, Optimum pressure can be applied to the hair, without damaging the hair externally or internally in various treatments such as hair treatment, pretreatment, perm, color, etc. There exists an effect that a chemical | medical agent can fully osmose | permeate the inside of hair.

The

  In this way, the grip 4 is assembled. As shown in FIG. 1, the comb 2 is attached to the end of the grip 4 and is operatively connected to the electric drive mechanism 3 incorporated in the grip 4. In this case, the comb 2 is detachably attached to the grip 4 (the drive shaft 37 of the electric drive mechanism 3) by connecting the connecting member 24 fixed to the attachment shaft 23 at one end to the drive shaft 37 at the end of the grip 4. It is done. And by the structure of this electric drive mechanism 3 as a whole, the amplitude of the reciprocating motion of the comb 2 is set to approximately one pitch of the comb teeth 21, and the number of vibrations of the reciprocating motion is set to 40 to 50 times / second. Accordingly, by operating the operation button 5 of the grip 4, the motor 32 (gear 33) is rotated, the gear 34 is rotated, and the cam 35 is rotated around the rotation shaft portion 342. The drive shaft 37 reciprocates in the length direction of the grip 4 on the opening 43 at the tip of the grip 4 through the rod 36 connected to the cam 35 (see FIG. 3), and is connected to the drive shaft 37. The comb 2 vibrates in the arrangement direction of the comb teeth 21 by a reciprocating motion with an amplitude of approximately one pitch of the comb teeth 21 and a vibration frequency of 40 to 50 times per second.

  When performing treatment using this electric hair comb 1, first, the hair epidermis (cuticle) covering the hair is opened by shampooing the hair to wet it or using a steamer to wet and warm the hair. . In this state, moisture is sufficiently swollen inside the hair and saturated. From this state, the electric hair comb 1 is used to perform treatment. First, the treatment liquid is attached to the hair. Next, as shown in FIG. 4, the grip 4 of the electric hair comb 1 is firmly held by hand, and the operation button 5 is operated with the thumb to vibrate the comb 2 (reciprocating motion). Then, as shown in FIG. 5, the treatment liquid is blended in while combing the hair with the comb 2. In this case, an appropriate amount is sliced, the comb 2 is inserted from below the portion where the treatment liquid penetration is to be promoted and gently pushed up, and gradually combed toward the hair tip, and this operation is repeated several times. In this combing, the comb 2 vibrates (reciprocates, the amplitude of the comb 2 is approximately one pitch of the comb teeth 21 and the frequency of vibration is 40 to 50 times per second, so that a suitable pressure is applied to the hair. The vibration of the comb 2 effectively drains moisture that has been saturated inside the hair, opens the hair epidermis, and drains moisture inside the hair. The treatment liquid can effectively penetrate into the hair, allowing the treatment liquid to penetrate into the hair by an allowable amount, and the reciprocating motion adopted in the comb 2, that is, the amplitude is approximately one pitch of the comb teeth 21 and vibrates. The vibration of 40-50 times per second does not damage the hair externally or internally, it is the optimal pressure for the hair, and does not damage the hair externally or internally. Treatment treatment The same process is repeated for each panel, and when slicing or blocking, press the pause button to pause and work. Press to stop the operation of the electric hair comb 1.

  As described above, in this electric hair comb 1, the amplitude of the reciprocating motion of the comb 2 is set to approximately one pitch of the comb teeth 21, and the number of vibrations is set to 40 to 50 times per second so that the comb 2 is vibrated. As a result, optimal pressure can be applied to the hair, and the treatment liquid can sufficiently penetrate into the hair without damaging the hair externally or internally during the treatment of the hair. Can do.

  Conventional treatment device (comb reciprocating motion with a comb reciprocating amplitude of 2.0 mm to 8.0 mm, preferably 4.0 mm, reciprocating vibration frequency set to 1000 to 5000 times / second) When this electric hair comb 1 was used for the actual treatment and its performance experiment was conducted, the conventional treatment device was able to sufficiently penetrate the treatment liquid into the inside of the hair, but external to the hair. It was confirmed that the comb vibration was excessive pressure (impact) against the hair. On the other hand, in the case of the electric hair comb 1, the treatment liquid can be sufficiently penetrated into the inside of the hair, and the hair is not damaged externally or internally, and the effects as described above are achieved. I was able to confirm.

  In the above-described embodiment, the case where the electric hair comb 1 is used for hair treatment is exemplified. However, in addition to the hair treatment, in various treatments such as pretreatment of hair, perm, color, etc. that penetrate the drug into the hair. Can be applied in the same manner, and the drug can be sufficiently penetrated into the hair without damaging the hair externally or internally.

  In the above embodiment, the electric drive mechanism 3 is constituted by the power supply unit 31, the motor 32, the gear 33, the gear 34, the cam 35, the rod 36, the drive shaft 37, and the like. 2 may be adopted as long as it can vibrate (reciprocate) in the arrangement direction of the comb teeth 21. In any case, the amplitude of the reciprocating motion of the comb 2 is approximately equal to that of the comb teeth 21. By setting the number of reciprocating motions within a range of 40 to 50 times per second for one pitch, the same effect as described above can be obtained.
