Description

  The present invention relates to an ultrasonic hair treatment apparatus that sandwiches hair between a vibration part and a receiving part, and transmits ultrasonic vibrations of a vibrator provided in the vibration part to the hair. Specifically, after applying a treatment agent, the vibration part And an ultrasonic hair treatment apparatus used as a treatment agent permeation apparatus that sandwiches the hair at a receiving portion and promotes the penetration of the treatment agent into the hair by ultrasonic vibration.

  The conventional hair styling device includes a vibrator that converts electrical signals into mechanical vibrations, and applies ultrasonic vibration generated by the vibrator to the hair and the treatment agent to promote penetration of the treatment agent into the hair. There is an ultrasonic hair treatment apparatus (see, for example, Patent Document 1).

  Further, in this ultrasonic hair treatment apparatus, a treatment agent applied to hair and hair while providing a vibrator in a hair treatment apparatus in which the ends of a pair of sandwiching members are rotatably connected to each other and sandwiched by the sandwiching member Is provided with ultrasonic vibration to promote penetration of the treatment agent into the hair, and this is used for, for example, a straight permanent.

  In this hair treatment apparatus, there is one in which a vibrating part having a disk-shaped vibrator is provided on one of the opposed surfaces of a pair of sandwiching members, and a receiving part facing the vibrating part is provided on the other. By rotating the pinching member, the hair bundle to which the treatment agent is applied is sandwiched between the vibrating portion and the receiving portion, and in this state, ultrasonic vibration in the thickness direction of the disk-shaped vibrator is applied to the hair bundle and the treatment agent by the vibration portion. By transmitting and radiating to the hair, penetration of the treatment agent into the hair is promoted, and the hair bundle is slid in the length direction (stretching direction) while sandwiching the hair bundle between the vibrating part and the receiving part. By applying ultrasonic vibration to the hair bundle from the disk-shaped vibrator, the treatment agent can be penetrated over the entire length of the hair bundle.

By the way, since the vibrator in the ultrasonic hair treatment apparatus has a disk shape, the amplitude in the thickness direction is the largest at the center and the amplitude is smaller toward the outer side in the radial direction. That is, since the resonance point (maximum amplitude point at which the amplitude in the thickness direction is maximum) of this disk-shaped vibrator is only one point at the center, the hair and the treatment agent are vibrated in the central portion of the disk-shaped vibrator. Although it can be vibrated at the periphery, the treatment agent cannot be uniformly permeated over the entire width of the hair bundle, and the periphery of the disk-shaped vibrator In particular, a sufficient amount of the treatment agent cannot be permeated at both ends in the width direction orthogonal to the length direction of the hair bundle, so that the treatment time becomes long.

Therefore, the treatment agent can be uniformly and surely permeated throughout the entire hair bundle, and in this case, the treatment time can be shortened and the power consumption can be reduced.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 1 shows an ultrasonic hair treatment apparatus 1 as an example of the present embodiment, and FIGS. 2 and 3 show usage forms of the ultrasonic hair treatment apparatus 1.

  As shown in FIG. 1, the ultrasonic hair treatment apparatus 1 connects a pair of long pinching members 2 a, 2 b that can be overlapped so as to be substantially overlapped with each other via a hinge portion 3. The turning member 2a, 2b has a rotational axis direction parallel to the short direction (width direction) of the long holding members 2a, 2b indicated by an arrow A.

  The ultrasonic hair treatment apparatus 1 rotates one of the pinching members 2a (lower side in FIG. 1) with respect to the other pinching member 2a (upper side in FIG. 1), so that both pinching members 2a, The facing surfaces 4a and 4b at the end opposite to the hinge portion 3 of 2b can be in a sandwiched state where the facing surfaces 4a and 4b are opposed to each other, or the facing surfaces 4a and 4b are separated from each other. It has become. In this example, a large number of bristle 9 is provided in the longitudinal direction B of the sandwiching members 2a, 2b on both sides of the opposing surfaces 4a, 4b of the sandwiching members 2a, 2b (more specifically, both sides of a vibrating portion 5 and a receiving portion 6 described later). Yes.

  A vibration part 5 is provided on the facing surface 4b of the sandwiching member 2b. The vibration part 5 is composed of a vibrator 7 that generates ultrasonic vibrations and a head 8 that is built in the state where the vibrator 7 is in contact. is there.

  The head 8 has a rectangular plate shape (specifically, a rectangular plate shape) and is made of, for example, a hard material (mainly aluminum). A rectangular concave portion 10 is formed on a surface facing the opposing surface 4a of the sandwiching member 2a.

  As shown in FIG. 4, the vibrator 7 has a rectangular plate shape (specifically, a rectangular plate shape), is fixed in a state of being fitted in the recess 10 of the head 8, and is sandwiched in the sandwiched state of FIG. It is parallel to the opposing surfaces 4a and 4b of 2b. One surface in the thickness direction (c) of the vibrator 7 is exposed to the sandwiching member 2a side, and one surface in the exposed thickness direction (c) is the vibration surface 7a.

The vibrator 7 is supplied with power from a power supply unit (not shown), and is electrically connected to a drive circuit 11 built in the sandwiching member 2b. The drive circuit 11 is further electrically connected to the control circuit 12. The output is controlled by the control circuit 12 by being connected. That is, by controlling the drive circuit 11 with the control circuit 12, an ultrasonic vibration can be generated by passing a current through the vibrator 7. Note that this ultrasonic vibration is generated under conditions of, for example, 500 kHz to 10 MHz and 0.1 to 5 W / cm ² .

  Here, the vibrator 7 utilizes a vibration mode in the thickness direction of the piezoelectric longitudinal effect. That is, when an electric current is passed through the vibrator 7, as shown in FIG. 4A, the vibrator 7 vibrates (expands and contracts) in the vertical direction (d) and the horizontal direction (e) in a plane orthogonal to the thickness direction (c). The vibrations in the vertical direction (d) and the horizontal direction (c) interfere with each other to generate vibrations in the thickness direction (c). As shown in FIG. 4B, the resonance point A (maximum amplitude point in the thickness direction (c)) vibrates so as to be positioned at multiple points in the form of lattice points.

  The opposing surface 4a of the sandwiching member 2a is provided with a receiving portion 6 facing the sandwiching member 2a side of the head 8 and the vibration surface 7a of the vibrator 7 that is flush with the same surface. The surface of the receiving portion 6 on the vibrating portion 5 side is a flat surface. The material of the receiving part 6 is preferably a hard material, like the vibration part 5, if it is desired to enhance the deformation effect of the hair such as a permanent, and if it is desired to enhance the effect of promoting the penetration of the treatment agent into the hair, it is a soft material. Is preferred. Further, in this example, the surface on the side of the sandwiching member 2a of the head 8 and the vibration surface 7a of the vibrator 7 which is flush with the same surface and the surface of the receiving portion 6 opposite to the surface are flat surfaces. For example, it may be arcuate so that it can be curled.

  Thus, for example, a treatment agent comprising a permanent agent, a hair dyeing agent, a treatment agent or the like is applied to the hair, and thereafter, the both sandwiching members 2a and 2b are sandwiched as shown in FIG. 2 in the longitudinal direction (b) Is arranged so as to be substantially orthogonal to the length direction (extending direction) of the hair bundle H, and is rotated so that the opposing surfaces 4a and 4b overlap each other as shown in FIG. 7 is sandwiched between the vibrating surface 7a) and the receiving portion 6, and in this state, the vibrator 7 is ultrasonically vibrated as described above, whereby the ultrasonic vibration of the vibrator 7 is changed to the hair bundle H and the treatment agent. Thus, the penetration of the treatment agent into the hair can be promoted.

  In the present application, as described above, the vibrator 7 vibrates so that the resonance point A is positioned at a plurality of lattice points as seen from the thickness direction (c) as shown in FIG. Therefore, the vibration surface 7a of the vibrator 7 can be vibrated uniformly over substantially the whole, and the treatment agent can be uniformly and surely permeated throughout the width direction of the hair bundle H. The treatment agent can be uniformly and surely permeated throughout the entire hair bundle H, the treatment time can be shortened, and the power consumption can be reduced. In addition, since the vibrator 7 of the present application uses the thickness direction vibration mode of the piezoelectric longitudinal effect, the vibrator 7 vibrates in the thickness direction (c) when a current is passed. (Elongation and contraction) and a mode in which vibration in the thickness direction (c) is obtained) can be improved in energy efficiency of ultrasonic vibration and power consumption can be reduced.

  Here, the vibrator 7 may have one side 7b of the vibration surface 7a parallel to the longitudinal direction (b) of the sandwiching member 2b as shown in FIG. 1, but one side 7b of the vibration surface 7a as shown in FIG. Is preferably inclined with respect to the longitudinal direction (b) of the sandwiching member 2b. An example in this case is shown below. In the following description, the same components as those in the above embodiment are given the same numbers, and redundant descriptions are omitted.

  In the example of FIG. 5, one side (for example, the long side) of one surface in the thickness direction of the rectangular plate-shaped head 8 is inclined with respect to the longitudinal direction (b) of the sandwiching members 2a and 2b. One side (for example, the long side 7b) of the vibration surface 7a of the built-in rectangular plate-like vibrator 7 is inclined with respect to the longitudinal direction (b) of the sandwiching member 2b.

  As described above, the vibrator 7 is disposed with the one side 7b of the vibration surface 7a inclined with respect to the longitudinal direction (b) of the sandwiching member 2b (that is, the length direction of the hair bundle H), whereby the longitudinal direction of the sandwiching member 2b. The number of resonance points A existing per unit length in the direction (b) (in the width direction of the hair bundle H) can be increased, thereby giving sufficient ultrasonic vibration to the hair bundle H and the treatment agent. In particular, the ultrasonic hair treatment device 1 can be moved in the length direction (extending direction) of the hair bundle H while the hair bundle H is sandwiched between the vibrating portion 5 and the receiving portion 6. This is effective when used by sliding from the proximal side to the distal side.

  The “inclination” of one side 7b of the vibration surface 7a of the vibrator 7 means that the inner angle between the one side 7b of the vibration surface 7a and the longitudinal direction (b) of the sandwiching member is less than 90 °, and 90 ° or more. Shall not be included. Further, the head 8 of this example is inclined with respect to the longitudinal direction (b) of the sandwiching member 2b like the vibrator 7, but the head 8 sandwiches one side as shown by the broken line in FIG. Although not shown in the drawings, the planar shape of the head 8 may be a shape other than a rectangle (for example, a disk shape).

  Next, another example of the ultrasonic hair treatment apparatus is shown in FIG. In this example, a plurality of sets of vibrating portions 5 and receiving portions 6 each having a rectangular plate-like vibrator 7 are arranged in parallel so that adjacent vibrating portions 5 are not in contact with each other, and at least one set of vibrating portions 5 is provided. And the positional relationship between the receiving part 6 and the other group is different, and the same components as those in the embodiment of FIG.

  As shown in FIG. 6, the vibrating part 5 and the receiving part 6 are in contact with a pair of the vibrating part 5 and the receiving part 6 in the short direction (i) of the sandwiching members 2 b and 2 a (that is, the length direction of the hair bundle H). 2 sets are arranged side by side, and in one set 13 (the set on the left side in the figure), the vibrating portion 5 is provided on the opposing surface 4b of the sandwiching member 2b and the receiving portion 6 is provided on the opposing surface of the sandwiching member 2a. In the other group 14 (the group on the right side in the figure) provided on 2a, the vibrating part 5 is provided on the opposing surface 4a of the sandwiching member 2a and the opposing surface 4b of the receiving part 6 is provided on the sandwiching member 2b. As a result, the positional relationship between the vibrating portion 5 and the receiving portion 6 of one set 13 is reversed from that of the other set 14. The arrow in FIG. 6 indicates the sliding movement of the hair bundle H when the hair bundle H is slid from the proximal end side to the distal end side in the length direction (extending direction) of the hair bundle H while the hair bundle H is sandwiched between the vibrating portion 5 and the receiving portion 6. Direction.

  Further, each vibration part 5 of this example includes a rectangular plate-like vibrator 7 provided on the sandwiching member 2b (or 2a) and a plate-like head 8 provided so that one surface is in contact with the vibration surface 7a of the vibrator 7. The surface of the head 8 opposite to the vibrator 7 is a radiation surface 15, which is a hair bundle formed by the radiation surface 15 of the head 8 and the receiving portion 6 facing the radiation surface 15. In the state where H is sandwiched, the vibration of the vibrator 7 is transmitted from the radiation surface 15 to the hair bundle H and the treatment agent by the head 8 and radiated to vibrate the hair bundle H and the treatment agent. In other words, in this example, when the vibrator 7 is ultrasonically vibrated, the radiating surface 15 of the head 8 is located at multiple points in the form of lattice points like the vibrating surface 7 a of the vibrator 7. It will vibrate.

  The vibrating units 5 are electrically connected to the corresponding driving circuits 11 a and 11 b, and the driving circuits 11 a and 11 b are connected to the control circuit 12. The control circuit 12 sets both the operation time and the stop time of the drive circuits 11a and 11b as T1 and T2 as shown in the time chart showing the outputs of the drive circuits 11a and 11b in FIG. 7, and the operation time T1 and the stop time T2 are The relationship is T1 ≧ T2, so that when the drive circuit 11a is operated (output is set to Hi) and the vibrator 7 of one set 13 is driven (vibrated), the drive circuit 11b is stopped. (The output is set to Lo), the vibration of the vibrator 7 of the other set 14 is stopped, and conversely, the drive circuit 11b is operated (the output is set to Hi). When driving (vibrating), the driving circuit 11a is stopped (the output is set to Lo), and control is performed so as to stop the vibration of the vibrator 7 of one set 13, and both the driving circuits 11a, 11b and Do not drive both vibrators 7 at the same time That. That is, in this example, the control circuit 12 and the drive circuits 11a and 11b are control units that alternately oscillate the vibrators 7 of the vibration units 5 of the sets 13 and 14.

  In this way, a plurality of sets 13 and 14 are arranged in parallel so that the adjacent vibrating section 5 is not in contact with the vibrating section 5 and the receiving section 6 having the rectangular plate-shaped vibrator 7, and at least one set of the vibrating sections 13 is provided. By reversing the positional relationship between 5 and the receiving portion 6 with respect to the other group 14, ultrasonic vibrations of the vibrator 7 can be applied from both the front and back sides of the hair bundle H, and the treatment agent can further penetrate into the hair. Can promote. In this case, the vibrating portions 5 of the different sets 13 and 14 are disposed so as not to face each other by shifting in the short direction (A) of the sandwiching members 2b and 2a. The generated ultrasonic vibrations do not cancel each other, and this point is also acceptable. Further, in this example, the vibrators 7 of the vibrating portions 5 of the two sets 13 and 14 are alternately oscillated, so that the supplied power can be suppressed to be equivalent to one vibrator or less, and the burden on the power source can be reduced. In addition, each vibrator | oscillator 7 of this example shall incline with respect to the longitudinal direction (b) of the pinching member 2b on one side 7b of the vibration surface 7a similarly to the Example of FIG.

  Further, the vibrating portion 5 in any of the above embodiments is not limited to the above-described one, and the hair bundle H is sandwiched between the vibrating surface 7a of the vibrator 7 and the receiving portion 6 as in the embodiment of FIG. The vibration unit 5 that directly transmits and radiates the vibration of the vibrator 7 to H and the treatment agent, or the hair bundle H is sandwiched between the head 8 and the receiving unit 6 as shown in FIG. Any of the vibrating sections 5 that transmit and radiate the vibration of the vibrator 7 to the agent via the head 8 may be used.

  In each of the above-described embodiments, as shown in FIG. 8, the opposing surface 4a of one of the sandwiching members 2a is disposed at two locations spaced in the longitudinal direction (b) of the sandwiching member 2a on the opposing surface 4b side of the other sandwiching member 2b. Protruding guide convex portions 16 are provided, and each guide convex portion 16 is provided at two positions in the longitudinal direction (b) of the sandwiching member 2b of the opposing surface 4b of the other sandwiching member 2b as shown in FIG. The fitting recesses 17 that can be fitted may be provided.

  In the illustrated example, the guide convex portions 16 of the one opposing surface 4a are provided in two places with a distance in the longitudinal direction (b) of both end portions in the short direction (A) of the sandwiching member 2b, a total of four places, The fitting recesses 17 of the other facing surface 4a are provided at a total of four places, two places at intervals in the longitudinal direction (b) of both end portions in the short direction (A) of the sandwiching member 2a. Although not shown in the drawings, the guide convex portions 16 and the fitting concave portions 17 are slightly more than the both end portions or both end portions of the vibrator 7 or the receiving portion 6 in the longitudinal direction (b) of the sandwiching members 2a and 2b. It is assumed that it is provided at a position that overlaps with the part separated outward.

  As a result, each guide convex portion 16 is fitted into the corresponding fitting concave portion 17, and the hair bundle H is sandwiched between the vibrating portion 5 and the receiving portion 6. In this state, the ultrasonic waves of the vibrator 7 are applied to the hair bundle H and the treatment agent. The hair bundle H can be passed between the guide convex portions 16 provided at intervals in the longitudinal direction (b) of the sandwiching member 2b, and the length of the hair bundle H can be increased by both guide convex portions 16. The ultrasonic hair treatment apparatus 1 can be guided so as to move smoothly along the vertical direction. In particular, in this case, the hair bundle H is vibrated by the guide convex portion 16 so that the vibration surface 7a of the vibrator 7 (that is, the region on which ultrasonic vibration acts). ) From outside.

  In this example, the guide convex portion 16 is provided on the opposing surface 4a of the sandwiching member 2a, and the recessed portion 17 is provided on the opposing surface 4b of the sandwiching member 2b. However, the guide convex portion 16 is provided on the opposing surface 4b of the sandwiching member 2b, A fitting recess 17 may be provided on the facing surface 4a of the sandwiching member 2a. The guide convex portion 16 and the fitting concave portion 17 may be provided in the head 8 or the receiving portion 6 of the vibrating body.

  In any of the above embodiments, it is preferable to provide a plurality of rectangular plate-like vibrators 7 in the thickness direction (c) on the vibrating portion 5. In the example of FIG. 10, the vibrator 5 includes two vibrators 7 superposed in the thickness direction (c), and a plate-like head 8 provided so that one face is in contact with the vibration face 7 a of the vibrator 7. Each vibrator 7 and the head 8 are fastened with bolts 18. Thus, by providing a plurality of rectangular plate-like vibrators 7 in the thickness direction (c) on the vibrating portion 5, the upper limit of the generated ultrasonic output can be increased. In this case, depending on the number of vibrators 7, The upper limit of ultrasonic output can be adjusted.
