Tip respective-1b spine plate portion of the inner surface side respectively disposed with left and right electrode plates 6a-6b having spring elasticity (7-10 view), side plates 3 _9.3 heater cartridge 30
Electrode plate 6a is the conductive pattern layer ₃₅ of the rear substrate _{3 2} relative to cutout window hole ₃ 18 - _{3 19} provided on the _tenth surface, the electrode plate 6
b is in the state of being electrically connected to pressure contact with the front substrate 3 _first conductive pattern layer 3 _3, also distribution in the cartridge mounting portion below the between the comb tooth plates 1a · 1b of the left and right comb teeth 1 tip of the spring plate 7 which is set is in contact with the front end side of the lower edge of the rear substrate 3 ₂ (8, 11 view), nichrome fine wire around the 11th diagram pin 3 ₁₅ against rear substrate 3 ₂ A counterclockwise rotational biasing force is applied against the tension of 3.

In the state where the heater cartridge 30 is attached to the comb tooth portion 1 (FIGS. 3 and 8), the nichrome thin wire 3 serving as an electric heating wire is placed within the gap w between the two comb tooth plates 1a and 1b. It is located near the base and stretched in the front-rear direction.

With the above heater cartridge mounted, the handle portion 2
When holding the switch and pressing the switch 5a or 5b, or both, the energizing circuit 8 (Fig. 9) is turned on, and the current of the power supply battery B changes from the electrode plate 6a to the conductive pattern layer 3 _{5 to the} nichrome thin wire 3 to the conductive pattern. Layer 3 ₃ → Flows in the path of the electrode plate 6b.

As a result, the nichrome thin wire 3 is instantly in a heat generating state over substantially the entire length. When the switch 5a or / and 5b is released, the circuit opens and the current is cut off.
Stops generating heat and has a small heat capacity, so the temperature drops rapidly.

Then, while combing the hair with the comb tooth portion 1, the nichrome thin wire 3 portion is brought into contact with an appropriate length portion of the hair and the switch 5
When a or / and 5b is pressed, the nichrome thin wire 3 becomes red hot, and the hair portion in contact with the nichrome thin wire 3 is easily burnt off. Unlike the case of shearing with a knife, the tips of the burnt-out body hair are not sharp and have roundness. Therefore, the above-mentioned inconvenience as in the case of using a blade does not occur.

Since the nichrome thin wire 3 is located between the left and right comb tooth plates 1a and 1b and is guarded, the nichrome thin wire 3 does not directly contact the skin.

Rear substrate and the protruding portions _{3 7} of the front base portion _{3 1} of the cartridge 30 3
Although nichrome fine wire 3 which is stretched between the _second protruding portions 3 ₈ causing extend linear expansion in the heat generated by energization, the centered pin 3 ₁₅ by the substrate 3 ₂ spring plate 7 after due to its extended 1
The spacing between the projections 3 ₇ and the protrusion 3 ₈ strung nichrome fine wire 3 rotates in the counterclockwise direction as shown in Figure 2 extends content of nichrome fine wire 3 is absorbed open, nichrome fine wire 3 I'm always in tension.

Therefore, the extension of the nichrome thin wire 3 may cause the nichrome thin wire to be too close to the inner surfaces of the left and right comb tooth plates 1a and 1b, or may come into direct contact with the inner surfaces of the comb tooth plates 1a and 1b to cause heat loss. To be prevented.

When the power supply to the nichrome thin wire 3 is cut off, the nichrome thin wire shrinks as it cools, and the shrinkage force causes the rear substrate 3 ₂
Spring plate returns around the pin 3 ₁₅ against the 7 from the state of Figure 12 rotated in a clockwise direction to the state of FIG. 11, the nichrome fine wire 3 with the projecting portion 3 ₇ and the protrusion 3 ₈ The tension is kept in the meantime. That is, the nichrome thin wire 3 is always maintained in a tensioned state without slack when energized or de-energized.

Further, in the case of this embodiment, even if the switch 5a or / and 5b is continuously pressed, a predetermined timer time (for example, 3
The energizing circuit 8 is provided with a timer function so that the energization of the nichrome thin wire 3 is automatically cut off after a lapse of 0 to 60 seconds). As a result, it is possible to prevent overheating and the like due to continuous energization of the nichrome thin wire 3, which is safe. The timer function is reset every time the switch 5a or 5b is pressed. After the timer is activated to turn off the energization, the switch 5a or / and 5b is pressed again to re-energize the nichrome thin wire.

Figure 14 is a lower edge of the rear substrate 3 _2, examples in which the plate spring 7 is notched 3 ₂₁ having a depth of about 0.3mm to abutting portions, 15
The drawing shows an example in which the notch 3 ₂₁ is further deepened and a notch 3 ₂₂ is also formed in the lower edge of the left and right side plates 3 ₉ 3 ₁₀ corresponding to the notch 3 ₂₁ .

With click feeling when completely mounted in the cartridge 30 by placing such a notch is obtained, the mounting state is stably maintained, also earn wide rotational angle range centered on pin 3 ₁₅ of the rear substrate 3 ₂ be able to.

The means for absorbing the linear expansion and extension of the nichrome thin wire 3 as the energized heat generating wire during the energized heat generation and maintaining the stretched state is not limited to the above example, but other means, for example, the end portion of the nichrome thin wire is directly pulled by a spring material. It is good to let it be in a state.

Reference numeral 9 is an energization pilot lamp (LED, green lamp, and red lamp) such as a light emitting diode provided on the tip side of the comb tooth portion 1. The lamp 9 is controlled by the energizing circuit 8, and when the switch 5a or / and 5b is pressed, the green lamp lights to indicate that the energization is being performed. At the time when the battery B is exhausted and needs to be replaced, the switch 5a
Or / and when 5b is pressed, the red lamp blinks and lights to indicate that.

When the nichrome thin wire 3 is broken, the lever 10 (Figs. 3-6 to 8) provided on the connecting portion of the comb tooth portion 1 and the grip portion 2 so as to be rotatable around the shaft 10a is shown in FIG. When turning operation in the counter-clockwise direction by a fingertip as a point mirror line shows, mounted knob portion of the rear substrate 3 _{and second} rear side leading end side of which the heater cartridge 30 by being pressed by the lever 10 3 ₂₃ a comb The tooth portion 1 projects outward from the tip end side.

Where it is the outer knob portion 3 which projects ₂₃ and upon mounting the cartridge by pinching with fingers replaced with a new heater cartridge 30 removed Remove the cartridge from between the left and right comb plate 1a · 1b by pulling in opposite directions use.

In this way, the energization heating wire (nichrome thin wire) 3 is of the detachable cartridge type, which improves the economy.

When not in use, the cap 4 of the battery box of the handle portion 2 is rotated counterclockwise by about 45 ° from the state where the marks 4a and 4c in FIG. 2 coincide with each other until the mark 4c coincides with the mark 4b. The switch 11 (FIG. 9) interlocking with the lid 4 is opened to open the battery circuit. In this state, even if the switch 5a or / and 5b is pressed, the nichrome thin wire 3 is not energized and it is safe. From this state, when the lid 4 is turned back in the opposite direction by about 45 ° and rotated to bring the marks 4a and 4c into the same state, the switch 11 is closed and the battery circuit is opened.

When the stopper lid 4 is rotated about 90 ° counterclockwise from the state where the marks 4a and 4c in FIG. 2 are aligned, the stopper lid 4 is detached from the handle portion 2 and the battery B can be taken in and out.

By storing the power supply battery S in the handle portion 2, it becomes cordless and easy to handle.

However, a configuration is provided in which a rear end portion of the handle portion 2 or the like is provided with a power receiving outlet, and a plug that can be freely inserted / removed is inserted into the outlet to supply power from a battery holder separate from the hair treatment tool through a cord. Alternatively, in this case, the weight of the hair treatment tool is light and easy to handle.

The hair treatment tool and a battery holder separate from the hair treatment tool may be directly connected to each other by an electric cord without an outlet / plug.

It is also possible to use a commercial power source and connect it to the hair treatment tool by a cord via a voltage drop device to energize the energization heating wire.

Since the hair treatment tool of the present invention has the above structure, it has the following effects.

a. Unlike the case where the hair is cut with a knife, it is used for treating unwanted hair on the arms, legs, and bikini line, and for hairdressing, etc. The tip creates a smooth flow and gives a natural feel. For the maintenance of split ends and broken hair, the rounded tips after cutting are easy to fit into the cut and are easy to organize, which makes the desired hairstyle last longer.

b. When the energization heating wire 3 is broken, it is enough to simply remove and replace the heater cartridge 30 with a new one with respect to the device body, and the device body is disassembled by removing the screws and the like, and there is no troublesome trouble of reassembling. The user can deal with it easily.
