The brush bristles 44b have a function of grabbing hair, have a length shorter than that of the bristles 44a, and are wider than the bristles 44a. In this way, by combining the brush hairs 44a and 44b of different materials, it is possible to comb the hair with a smooth feel.

  As shown in FIGS. 3 and 7, the heating unit 5 is fixed by a brush base unit 43 so as to cover the curved reflecting plate 42a, and generates heat by energization from a battery 61 described later. As shown in FIG. 8, the heating unit 5 is obtained by integrally molding a sheet heater 52 (heater) on the sheet holding unit 51, for example, by integrally molding by double molding. The planar heater 52 is in close contact with the back side of the sheet holding unit 51.

  The sheet holding unit 51 is a sheet-like member that holds heat, and is made of a rubber material such as silicone, which is a material having low thermal conductivity and difficult to escape heat. The sheet holding portion 51 is formed with a large number of insertion holes 51a through which the bristles 43a and 43b are inserted, and a vertically long slot 51b is also formed so as to avoid the formation positions of the planar heater 52 and the insertion holes 51a. Yes. The long hole 51b is formed in such a size that the brush bristle assembly 44 can be inserted.

  The planar heater 52 is, for example, a film heater insulated with polyetherimide, and generates heat when energized from a battery 61 described later. The planar heater 52 is formed by dividing a thin linear conductive path having a thickness of, for example, about 0.3 mm and a width of 1.0 mm to 2.0 mm into an outer peripheral region and a central region of the sheet holding unit 51. It is. The planar heater 52 is provided with a linear conductive path having a small thickness and a small width, thereby reducing the power to be supplied to the planar heater 52 as much as possible, so that the heating unit 5 can be used even in the battery 61 described later with a small battery capacity. Can be raised to 160 ° C. The planar heater 52 is bendable and has excellent durability with excellent pulling, bending and wear.

  The planar heater 52 is integrally molded with a temperature detection unit (temperature detection means) 53 that detects the heat generation temperature of the planar heater 52. The temperature detection unit 53 detects the temperature by using a decrease in resistance value accompanying a temperature increase, such as an NTC thermistor.

  As shown in FIG. 8, the planar heater 52 includes an outer peripheral surface heater 52 a (heater) arranged in the outer peripheral region of the sheet holding unit 51 and a central surface arranged only in the central region of the sheet holding unit 51. And a heater 52b (heater). The central planar heater 52b is controlled to generate heat at a temperature higher than that of the outer peripheral planar heater 52a, and gradually decreases the temperature from the center of the heating unit 5 toward the outer periphery to give heat to the hair. It is designed to make your hair easier to curl and wave.

  In the case where the outer peripheral surface heater 52a and the central surface heater 52b are configured, the temperature detection unit 53 may be integrally formed only on the central surface heater 52b. Since the central planar heater 52b is controlled at a higher heat generation temperature than the outer peripheral surface heater 52a, if only the high heat generation temperature of the central planar heater 52b is detected, the heat generation surface of the planar heater 52 is more than necessary. It is possible to prevent the hair from being damaged. Further, with this configuration, it is not necessary to provide the temperature detection unit 53 in each of the outer peripheral surface heater 52a and the central surface heater 52b, so that the manufacturing cost for manufacturing the heating unit 5 can also be reduced.

  As shown in FIGS. 3, 4, and 6, the grip portion 6 is made of, for example, a resin material and is formed in a substantially cylindrical shape so that the practitioner can easily grip it. The gripping unit 6 includes a battery 61 and a storage unit 62 that stores the battery 61. In addition, the grasping unit 6 includes a display unit 63 that displays the operation state of the heating unit 5, an operation unit 64 (temperature setting unit) that receives an operation input of the practitioner and sets the heat generation temperature of the heating unit 5, and an operation unit And a control unit 65 that controls the heat generation temperature of the heating unit 5 and the display state of the display unit 63 according to the set temperature of 64 and the temperature detected by the temperature detection unit 53.

  On the back surface side of the gripping portion 6, a lid portion 62 a that can be removed to allow the battery 61 to be housed in the housing portion 62 is formed.

  The battery 61 is, for example, a livestock battery such as a lithium ion battery, a nickel / cadmium battery, a nickel hydride battery, or a lead battery, or a battery such as an alkaline battery, a manganese battery, or a nickel battery. The battery 61 has at least a battery capacity of 3.6 V and 2900 mAh.

  The display unit 63 is formed on the front side of the grip unit 6 and is, for example, an LED or a panel LED. The display unit 63 is formed to light up during the operation of the heating unit 5. For example, the lighting of the display unit 63 may be changed according to the set temperature set by the operation unit 64.

  The operation unit 64 is formed on the front side of the gripping unit 6 and is configured so that the set temperature of the heating unit 5 can be set in multiple stages (for example, 90 ° C., 140 ° C., 160 ° C.). The operation unit 64 sets a set temperature based on an operation input from the practitioner, and transmits this set temperature information to the control unit 65. In addition, the operation unit 64 transmits power on / off information to the control unit 65 based on the operation input of the practitioner.

  As shown in FIG. 6, the control unit 65 is, for example, a control board on which a CPU (Central Processing Unit) or the like is mounted, and is electrically connected to the heating unit 5, the battery 61, the display unit 63, the operation unit 64, and the like. ing. The control unit 65 controls the lighting of the display unit 63 and the energization operation from the battery 61 to the heating unit 5 according to the set temperature of the operation unit 64 and the detected temperature of the temperature detection unit 53.

  Here, the control unit 65 may perform an energization operation from the battery 61 to the heating unit 5 by pulse control. That is, the control unit 65 sets the energization operation from the battery 61 to the heating unit 5 (the outer peripheral surface heater 52a and the central surface heater 52b) to 1 millisecond as shown in FIG. 9A, for example. It is preferable to perform the pulse control at the same timing to turn on and off the current of 5.8 A with the duty ratio per cycle being 50%.

  Next, the effect of this pulse control will be described. In order to prove this effect, the applicant conducted an operation time confirmation test and an exothermic temperature confirmation test. The battery 61 used in these confirmation tests was a fully charged lithium battery for portable equipment having a battery capacity of 3.6 V and 2,900 mAh.

<Operation time confirmation test>
In the confirmation test of the operating time, when the discharge time of the fully charged battery 61 is constantly discharged with a current of 2.9 A (always discharging), the discharge repeatedly turns on and off the current of 5.8 A per millisecond. Measurement was performed in the case of pulse control (pulse control). The results are shown in Table 1.

Table 1 Confirmation test results of operation time

  As can be seen from Table 1, when the pulse control was performed (pulse control), it was confirmed that the discharge time of the battery 61 was increased by about 1.2 times compared to the case of the constant discharge.

<Confirmation test of heat generation temperature>
In the exothermic temperature confirmation test, in the hair iron brush 2 of the present embodiment, when the energization is always performed (always energization) and in the case of pulse control in which energization is repeated on and off for 1 millisecond (pulse control), the heating unit The maximum exothermic temperature and operating time of 5 were measured. The results are shown in Table 2.

Table 2 Results of heat generation temperature confirmation test

  As can be seen from Table 2, the maximum heat generation temperature of the heating unit 5 rose to 160 ° C. to 200 ° C. in both cases of constant energization and pulse control. However, it was confirmed that the operation time of the heating unit 5 was 20 minutes when the current was always applied, but extended to 35 minutes when the pulse control was performed.

  That is, when the pulse control is performed, the operating time of the heating unit 5 is 1.75 when the energization is always performed, even though the heat generation temperature of the heating unit 5 can be increased to almost the same temperature as when the energization is always performed. It was confirmed that it could be up to twice as long.

  As is clear from the results of the confirmation test, the control unit 65 performs energization from the battery 61 to the heating unit 5 by pulse control, thereby suppressing a decrease in battery capacity and operating time compared to a case where energization is always performed. Can be made longer.

  Further, when the control unit 65 performs an energization operation from the battery 61 to the heating unit 5, the pulse control of the outer peripheral surface heater 52a and the central surface heater 52b may be performed with a phase shift.

  Specifically, as shown in FIG. 9B, the control unit 65 applies a current of 5.8 A per cycle for the energization operation from the battery 61 to the outer peripheral surface heater 52a and the central surface heater 52b. It is preferable to perform pulse control that is turned on and off in milliseconds, and to shift the pulse control phases of the outer peripheral surface heater 52a and the central surface heater 52b. That is, the controller 65 sets the energization operation from the battery 61 to the outer peripheral sheet heater 52a at the timing shown in the upper part of FIG. 9B, and the energization operation from the battery 61 to the central sheet heater 52b in FIG. It is good to set it as the timing as shown in the lower stage of b) (the timing which the phase shifted from the outer peripheral surface heater 52a).

  In this way, the energization of the outer peripheral surface heater 52a and the central surface heater 52b from the battery 61 is performed by pulse control with the phase shifted, thereby preventing the amount of heat supplied to the sheet holding unit 51 from being excessive, Power consumption can be suppressed and the capacity of the battery 61 can be reduced.

  Further, the sheet holding unit 51 can be held at a sufficient temperature for curling or waving the hair, with a sufficient amount of heat applied to the sheet holding unit 51.

  The hair iron brush 2 of the present embodiment generates heat in the sheet heater 52 formed by a thin conductive path, and the area of the sheet holding portion 51 serving as a heat generation surface by the long hole 51b is set to the minimum necessary size. Thus, even when energizing from the battery 61 having a small battery capacity, the heat generation temperature of the heating unit 5 can be increased to 160 ° C.

  Thereby, since the hair iron brush 2 of the present embodiment can secure a sufficient heat generation temperature of the heating unit 5 even if the battery capacity of the battery 61 is reduced, the size of the battery 61 is made compact, and the battery 61 The weight of can also be reduced. That is, the hair iron brush 2 of the present embodiment can make the battery 61 compact and lightweight, so that the entire hair iron brush 2 can be made compact and lightweight, and the portability of the hair iron brush 2 can be improved.

  The hair iron brush 2 of the present embodiment distributes the outer peripheral surface heater 52a and the central surface heater 52b in a plurality of places to the sheet holding unit 51 so that heat from the heating unit 5 is not evenly distributed to the hair. The hair curl and wave intended by the practitioner can be formed.

  The hair iron brush 2 of the present embodiment can extend the operating time to 30 minutes or more by pulse control even with the battery 61 having a small battery capacity, so that it is generally a time required for curling hair to be 15 minutes. Can be secured sufficiently.

  The hair iron brush 2 of the present embodiment is different from the base cover portion 42 in which a large number of brush hairs 42b are erected on both side ends and the brush base portion 43 in which a large number of brush hairs 43a and 43b are erected. The brush hairs 44a, 44b are combined together, and the brush hairs 44a, 44b are integrally combined, so that the brush hairs stand up in a range of about 180 ° or more, and the brush hairs 42b, 43a, 43b, 44a, The hair can be combed smoothly at 44b.

  Moreover, the hair iron brush 1 with a cover of the present embodiment covers and protects a large number of brush hairs 43 a and 43 b and the heating unit 5 by inserting the cover part 7 into the brush base 4, and the pressing protrusion 71 By operating the cut-off switch 41a, malfunction of the heating unit 5 can be prevented.

  Further, in this embodiment, the cutoff switch 41a uses a mechanical switch that directly shuts off the circuit, but is not limited to this, and the controller 65 indirectly shuts off the circuit. For example, it may be a method of blocking after adding judgment by an MCU.

  Next, an assembling operation of the hair iron brush 2 of the present embodiment will be described. As an initial condition, it is assumed that the battery 61 is accommodated in the accommodating portion 62 and the curved reflecting plate 42 a is fixed to the base cover portion 42. In addition, a large number of brush hairs 43 a and 43 b are provided on the brush base portion 43, and a plurality of types of brush hairs 44 a and 44 b are combined with the brush hair assembly 44.

  FIG. 10 is an operation flowchart showing an assembling operation of the hair iron brush 2 shown in FIG.

  As shown in FIG. 10, the operator fixes the brush base portion 43 to the front side of the base cover portion 42 (STEPs 11 and 12). When the base cover part 42 and the brush base part 43 are fixed, the operator inserts the heating part 5 into the brush base part while inserting a large number of brush hairs 43a, 43b erected on the brush base part 43 into the insertion hole 51a. It fixes so that the surface of 43 may be covered (STEP13).

  After fixing the heating unit 5 to the brush base unit 43, the operator inserts the brush bristle assembly 44 into the long holes 43c and 51b and fixes the brush bristle assembly 44 to the base cover unit 42 (STEP 14). ).

  Then, the operator fixes the brush bristle assembly 44, the heating unit 5 and the brush base unit 43 so as to cover the depression of the brush base body 41 with the base cover unit 42 integrally fixed (STEP 15). Then, the assembling work of the hair iron brush 2 is finished (STEP 16).

  At this time, the outer peripheral edge of the sheet holding unit 51 in the heating unit 5 is fitted into the brush base body 41 and fixed. By fixing in this way, it is possible to prevent the sheet holding portion 51 located on the front side of the brush portion 3 from floating when the practitioner combs the hair.

  The hair iron brush 2 of the present embodiment is composed of only five components as the brush portion 3, the brush bristle assembly 44, the heating portion 5, the brush base portion 43, the base cover portion 42 and the brush base body 41. As a result, the assembly work can be simplified.

  The hair iron brush 2 of the present embodiment can prevent excessive heat from being applied to the hair by positioning the sheet holding unit 51 having low thermal conductivity on the front side of the heating unit 5.

  In the hair iron brush 2 of the present embodiment, a sheet heater 52 is integrally formed as a heating section 5 on a sheet holding section 51 excellent in heat retention, and the sheet heater 52 is sandwiched between the sheet holding section 51 and the curved reflector 42a. By positioning in this manner, the amount of heat generated from the planar heater 52 is efficiently stored in the sheet holding unit 51, and the amount of current flowing from the battery 61 to the heating unit 5 is reduced, thereby reducing the battery capacity and reducing the weight. Thus, the size can be made compact.

  In particular, the heating part 5 is formed by double molding of a film heater and silicone, so that the heating temperature of the heating part 5 can be up to 160 ° C. even when the battery 61 is a single AA battery with a capacity of 3.6 V and 2900 mAh. Can be raised.

  Moreover, the hair iron brush 2 of a present Example is radiated | emitted to the back surface side of the curved reflector 42a by forming the heat insulation means (not shown) which has the space or the heat insulation function in the back surface side of the curved reflector 42a.

The control unit 65 also acquires detected temperature information from the temperature detecting unit 53 (STEP 25), and determines whether or not the detected temperature is equal to or higher than a set temperature (STEP 26).

  When there is no operation of the operation unit 64 by the practitioner, the control unit 65 determines that there is no power-on information (STEP 22 NO), and determines again whether there is power-on information (STEP 22).

  When the control unit 65 determines that the detected temperature is lower than the set temperature (NO in STEP 26), the battery 61 energizes the heating unit 5 (planar heater 52) (STEP 27). The control unit 65 acquires the detected temperature information of the temperature detecting unit 53 again (STEP 25), and determines again whether or not the detected temperature is equal to or higher than the set temperature (STEP 26).

  When the control unit 65 determines that the detected temperature is equal to or higher than the set temperature (STEP 26 YES), the control unit 65 stops energization from the battery 61 to the heating unit 5 (STEP 28), and the power is turned off from the operation unit 64. It is determined whether or not information has been acquired (STEP 29). When the practitioner continues to use the hair iron brush 2, since the power-off information is not acquired from the operation unit 64, the control unit 65 determines that the power-off input has not been made by the operation unit 64. (STEP 29 NO), the temperature detection unit 53 again acquires the detected temperature information, and determines whether or not the detected temperature is equal to or higher than the set temperature (STEPs 25 and 26).

  When the practitioner operates the operation unit 64 to turn off the power, the control unit 65 acquires power-off information from the operation unit 64 (STEP 30 YES), turns off the display unit 63, and performs the heat generation operation of the hair iron brush 2. The process ends (STEPs 30 and 31).
