Description

  The present invention relates to a body hair treatment tool used for treatment of unwanted hair such as bikini lines, heels, legs and arms, and hair conditioning.

  For example, when using a blade such as a razor or a razor to treat unwanted hair, such as before wearing a high-leg swimsuit or leotard, the trimmed hair tip is sharp due to shearing by the blade, and the sharp tip easily pierces the fabric. There are times when you peek outside and the touch becomes pleasing.

  Therefore, the present inventor has invented and put to practical use a heat-cutting device that burns off body hair with a heating wire (electric heating wire) as a hair treatment tool that can cut and trim the hair by rounding the hair tip ( For example, see Patent Documents 1 to 10).

  This is arranged between the two comb teeth plate portions arranged in parallel at an interval of about 5 to 10 mm, and the comb teeth of the comb tooth plate portion disposed between the two comb tooth plate portions. It has a basic structure of a heating wire, specifically a nichrome wire, that burns away the contact hair by contacting with the hair and energizing it.

  Hair is easily burned out when it comes into contact with red-hot nichrome wire. Unlike the case where the cut ends of the burned body hair are sheared with a blade, the hair ends are not sharp and rounded, and there is no problem as with the blade.

It is also effective as a hairdressing instrument for hairdressing and cosmetology. That is, the nichrome wire portion is contacted and slid on the hair end portion that has been conditioned and processed into a burned-out state, whereby the hair end can be rounded, subtlely curved or curled, and the hair can be given a unique texture.

Be drunk.

  In a state where the rotary head portion 9 is incorporated in the rotary head accommodating pocket portion 7 so as to be rotatable around the longitudinal axis portions 33 and 35, the O-rings 37 on the upper surface side and the lower surface side of the rotary head portion 9 are respectively the rotary heads. The inner pocket 7 is brought into frictional contact with the inner surface. Due to the frictional contact of the O-ring 37, the rotary head portion 9 is stably held at any rotation angle position within the rotation angle range (FIG. 6). As described above, the rotation head portion 9 including the comb tooth portion 3 can be rotated with respect to the body hair treatment tool base 8 to adjust the direction of the comb tooth portion, thereby improving the usability of the body hair treatment tool.

  FIG. 15 is a block diagram of an electric circuit system. Reference numeral 100 denotes a commercial AC power source. As described above, the AC-DC converted power supplied to the electric circuit of the hair treatment tool 1 is lowered to a predetermined voltage from the commercial AC power source through the power adapter 101, the output cord 102, the output plug 103, and the power receiving socket 13. Is made.

  Reference numerals 51, 52, 53, and 54 denote a control circuit, a heating wire driving circuit, an illumination lamp driving circuit, and a vibro motor driving circuit provided on the electric circuit board built in the hair treatment tool 1. The control circuit 51 is configured such that at least one of the pair of left and right switch push buttons 6 and 6 is pressed and the corresponding micro switch 14 is turned on, so that the heating wire drive circuit 52, the illumination lamp drive circuit 53, and the vibro motor drive circuit 54 is turned on. The timer function unit of the control circuit 51 starts to operate.

  When the heating wire driving circuit 52 is turned on, the heating wire 27 is energized, and the heating wire 27 becomes red. When the illumination lamp driving circuit 53 is turned on, the illumination lamp 17 is turned on. Further, when the vibrator motor drive circuit 54 is turned on, the vibrator motor 15 is driven.

  When the illumination lamp 17 is turned on, the light passes through the inside of the rotary head 9 and brightly illuminates the interiors of the two upper and lower comb tooth plate portions 24 and 23 of the comb tooth portion 3. Further, light is emitted from the upper and lower two comb-tooth plate portions 24 and 23 to the outside of the rotary head 9. In FIG. 3, L indicates illumination light emitted from the upper and lower two comb-tooth plate portions 24, 23 to the outside of the rotary head 9.

  For this reason, while the body hairs are arranged at the comb teeth 3, the operation of bringing the heated and heated portions of the comb teeth 3 in contact between the comb teeth into contact with the heated red wire is performed under bright illumination. it can. In the current situation, the inside of the comb teeth is dark, and the room lighting is often shielded by its own shadow when cutting, so it was difficult to perform the cutting operation. By providing the illumination lamp 17 to be used, usability can be improved.

  The illumination lamp 17 also serves as a pilot lamp. When the illumination lamp 17 is turned on, the inside and outside of the comb tooth portion 3 are brightly illuminated, so that it can be recognized that the heating wire 27 is energized.

  In addition, the hair treatment tool 1 is vibrated by driving the vibro motor 54. In the case of the current hair treatment tool, when cutting hair, the majority of users pull the hair with their fingers and apply a heating wire while applying tension. In this case, the cut ends tend to be poorly rounded. Ideally, it is desirable to burn off without applying tension to the hair, that is, only by applying a heating wire. By giving vibration to the hair treatment tool 1 as in this embodiment, fine vibration is given to the hair arranged in the comb teeth portion 3 to reduce the tension and make the cut surface of the hair as round as possible. be able to. Further, the hair of the comb teeth 3 vibrates due to the vibration of the comb teeth portion 3 so that the body hair is easily aligned at the comb teeth portion 3. As a result of the test, the vibration applied to the hair treatment tool 1 is sufficient to be about the vibration of a mobile phone.

  Moreover, the hair treatment tool 1 of the present embodiment is configured such that the energization circuit for the heating wire 27 is turned on when the switch is turned on and the switch-on state is maintained, but after the predetermined timer time has elapsed since the switch-on, It has a timer function that cuts off the power to the heating wire. That is, after the timer function unit starts timing operation when the micro switch 14 is turned on, the control circuit 51 continues to turn on the micro switch 14 and when the timer function unit clocks the timer time of about 30 seconds in this embodiment, Even if the switch 14 is still on, the driving of the heating wire driving circuit 52, the illumination lamp driving circuit 53, and the vibro motor driving circuit 54 is once turned off. Thereby, the overheating trouble by energizing the heating wire 27 continuously is avoided. When the illumination lamp 17 is turned off and the vibration due to the driving of the vibro motor 15 is stopped, the timer function is recognized. When the switch push button 6 is pressed again to turn on the micro switch 14, the timer function unit is reset and the heating wire driving circuit 52, the illumination lamp driving circuit 53, and the vibro motor driving circuit 54 are turned on again.

  As the heating wire 27, a nicolec wire can be used. In the present embodiment, a relatively thick material (for example, φ0.2 to 0.32 mm) having a small thermal expansion tarmi in a red hot state (400 ° C.) is used. By using a thicker one, the problem of disconnection can be eliminated.

  When the heating wire 27 is energized and heated, if the length is the same, the expansion will be the same, and even if the wire diameter is large, tarmi will occur. In this embodiment, the stem 30 is provided on the heating wire 27 as described above (FIGS. 8 and 10) in order to remove the thermal deformation of the comb teeth due to the approach of the tarmi. The stem 30 is made of stainless steel plate press, while the piano wire 32 is used together to provide springiness, and even if it occurs, it is pushed forward so that it does not come into contact with the inside of the comb teeth even if it occurs. The distance from the lower comb teeth is maintained. In this way, a relatively thick heating wire 27 is used, and a stem is provided in the middle to minimize tarmi and, as a result, the addition of a self-tensioning mechanism that automatically applies tension is fixed. , Streamline production lines and reduce costs.

  Further, in the hair treatment tool 1 of this embodiment, the lower comb tooth plate portion 23 of the rotary head portion 9 is on the lower surface side of the lower housing 21 of the rotary head portion 9 for cleaning internal and external cutting waste of the comb tooth portion 3.

In this example, illumination lamps (for example, high-intensity white LEDs) 17 and 17 are disposed inside the rotary head portion 9 and on both sides of the comb-tooth portion 3, respectively. As the illumination lamps 17 and 17 are turned on, the insides of the upper and lower two comb-tooth plate portions 24 and 23 of the comb-tooth portion 3 are illuminated brightly. In addition, light is emitted to the outside of the rotary head 9 from between the upper and lower two comb-tooth plate portions 24 and 23. The upper housing 22 of the rotary head portion 9 is provided with small window portions 22b and 22b on both sides of the comb tooth plate portion 24 so as to correspond to the front surfaces of the illumination lamps 17 and 17, respectively. Light is emitted from the rotating head 9 also from 22b and 22b. Accordingly, the inside and the front of the comb tooth portion 3 of the hair processing tool 1 are illuminated. L indicates the front illumination light. In FIG. 21, reference numeral 40 denotes a printed circuit board having the illumination lamps 17 and 17 described above. The substrate 40 is assembled to the lower housing 21 of the rotary head unit 9. In the assembled state, the electrical contacts 40a, 40a on the substrate 40 side elastically contact the contacts 26b, 26b provided on the heating wire supporting electrode plates 26, 26, and the substrate 40 is used for supporting the heating wire. The electrode plates 26 and 26 are electrically connected. Thereby, when the heating wire 27 is energized as described above, the illumination lamps 17 and 17 are also energized.

  Alternatively, the upper surface of the upper housing 22 of the rotary head unit 9 may be configured to be externally arranged so as to illuminate the inside and the front of the comb-tooth portion 3.
