2. Description of the Related Art For example, when a blade such as scissors or a razor is used to treat waste hair before wearing a high-leg swimsuit or a leotard, the trimmed hair tips are sharp due to shearing by the blade,
The pointed hairs may easily penetrate the fabric and look outwards, or the texture may be tedious.

Therefore, the applicant of the present invention has devised and put into practical use a heat-cutting device having a heat-cutting structure in which an electric heating element (such as a nichrome wire) burns down the hair as a hair-removing tool capable of rounding and trimming the hair tips. Registered (utility model registration No. 196724
No. 7 (Executive Examination No. 4-37521), No. 2046882 (Exact Examination No. 6-14649), No. 3006125 (Registered Utility Model Publication No. 3006125), Design Registration No. 857135).

This is basically an electric heating element which comes into contact with the comb teeth and the body hair inserted between the comb teeth of the comb teeth and is energized to generate heat (red heat) to burn off the contact body hair. The hair is made to have a structure, and by combing the hairs together with the comb teeth and bringing the portion of the heating element that has been energized and heated into contact with the hair, the portion of the hair that is in contact with the heating element is easily burnt off. The tip of the burned-out body hair is not sharp unlike the case of being sheared by a knife, and is rounded, so that there is no problem as in the case of a knife.

[0005] It is also effective as a hairdressing tool for hairdressing and cosmetology. That is, by applying an electric heating element portion to the sliding end of the hair to slide it to treat it in a burned-out state, the tip of the hair may be rounded, delicately curved or curled to give the hair a unique texture.

A practical product of the above invention has a handle portion (apparatus body) and a head portion on the tip end side of the handle portion, and a comb tooth portion and a comb tooth of the comb tooth portion are inserted into the head portion. In addition, it is provided with an electric heating element that comes into contact with the body hair and is energized to generate heat to burn off the contact body hair. Handle part

The power consumption of the energization heating element is about 4 W, and the dry batteries housed in the handle portion are single 2 type 3 series. The electric heating element is a heater cartridge that can be attached to and detached from the comb teeth of the head.

[0007]

[Problems to be solved by the invention] Sometimes you want to cut the hair from the hairline,
The above-mentioned practically used product of the above invention has a feature that the hair tip can be rounded to cut the hair, but it cannot cut the hair from the hairline.

[0008] Therefore, it is an object of the present invention to be able to deal with the cutting process of hair from the hairline.

[0009] Further, in the practical use product of the above-mentioned invention, since the inside of the handle portion is used as a battery storage portion for accommodating three AA type dry batteries in series, the handle portion becomes relatively long, and as a result, a head having the handle portion and the comb tooth portion is provided. The total length of the device including the parts is about 210 m / m, which is not necessarily convenient for carrying.

Therefore, the present invention has an object to further improve the portability of this device.

[0011] The practical product of the above-mentioned invention is a heater cartridge which is detachable and replaceable on the comb tooth portion of the head of the appliance for the energization heating element, so that the energization heating element can be prevented from being contaminated or damaged (disconnection). Although it is done by replacing the heater cartridge, there is no countermeasure against contamination or damage to the comb teeth.

That is, since the electronic circuit board and the energizing circuit for the energizing heating element are built in the instrument head in which the comb tooth portion is integrally provided in series, the comb tooth portion is internally and externally washed with a cleaning solution or a disinfectant solution. However, it is impossible to completely wash or disinfect the whole body, and it is necessary to wipe the outer surface of the comb tooth. Even if the comb teeth are broken or broken, the outer shells of the comb teeth, the head and the handle of the device cannot be dealt with because they are a single molded product. If it is violent, it is uneconomical to discard the entire device.

Therefore, an object of the present invention is to make it possible to sufficiently deal with the contamination and damage of the comb teeth.

Generally, a shaver for shaving is composed of a fixed blade fixed to the instrument body and a movable blade which reciprocates or rotates relative to the instrument body, and is provided on the fixed blade. The hair (whisker) that entered the open hole was cut with a movable blade. In addition, the shaver used for the fir tree also has a U-shaped opening with one end open instead of a hole with a closed periphery, but it is completely different in that it has a fixed blade and a movable blade. Considered the same.

On the other hand, when it comes to body hair, "beard"
With the upright bristles seen in etc., it is possible to easily enter even an open part with a closed periphery, so even if it is one equipped with such fixed blades and movable blades, it does not matter at all. Rather, on the other hand, it seems that this was the preferred method.

However, the body hair other than the whiskers is generally long and bent or shortly bent, depending on the part, and such a body hair has an opening portion whose periphery is closed. Can't be reached in the middle, thus causing disconnection problems. In this case, the one having an open hole at one end for the fir tree can enter, but the sharpness of the blade for securing the strength of the fixed blade cannot be made sharp, so that the sharpness is sharp. It wasn't good, except for the beard.

In the case of the shaver head B of the present example, such troubles concerning hair cutting can be drastically improved. That is, as already mentioned, the root cause of the problem is that the fixed blade and the movable blade are clearly separated from the main body, and secondly, the relative movement is reciprocating or unidirectional. You are choosing one of the rotational movements.
In this example, these two points are first of all modified, first of all, two blade plates 6
The a and 6b are movable blades that move equally in the opposite directions with respect to the main body, and secondly, the movement is fan-shaped vibration that has both reciprocating and rotating characteristics. . Furthermore, the movable blade is provided with a U-shaped opening with one end open to facilitate the entry of bent body hair. As a result, the mechanism of this example has a large number of minute scissors arranged in a row. It will behave as if they were operated at the same time,
It has become possible to drastically eliminate the conventional problems associated with cutting bent body hair.

(G) Others 1) The structure for attaching / detaching the heater head B and the shaver head C to / from the grip portion A, and the structure for attaching / detaching the comb teeth 3 and 5 to the head body of the heater head B and the shaver head C are shown in the illustrated example. Not limited to the screw type, the elastic hook-shaped leg type, and the pin insertion type, other arbitrary means configurations can be used.

2) The comb tooth plate of the comb tooth portion 3 of the heater head B may be configured to have only one comb tooth plate.

3) The energization heating element 2a of the heater head B, including the power supply electrode members 2b and 2c on both ends thereof, can be constructed as a heater cartridge which is detachable from the heater head body.

It is better to have it on the side.

4) The energization heating element 2a is the power feeding electrode member 2
a linear body or a rod-shaped body extending between b and 2c, and the linear body or the rod-shaped body includes an energization heating element electrically connected between the power feeding electrode members and the energization heating element. It is heated by the heat of the energization heating element to indirectly generate heat, and the energization heating element pulling means is constituted by an insulating shell that does not substantially expand or loose between the power feeding electrode members due to linear expansion due to the heat. There is no need to dispose and arrange, and the structure of the device can be simplified.

FIG. 19 is a structural schematic diagram of an example of such an electric heating element 2a. The energization heating element 2a of this example uses a nichrome thin wire of 0.1 to 0.14 m / mφ as a core wire (energization heating wire) a, and a cylindrical body c having an inner surface provided with an insulator b such as alumina. (For example, drawing material such as nickel)
It is a rigid, thin rod-shaped body that is inserted into or accommodated in. d and d are lead portions of the nichrome thin wire a exposed from both ends of the cylindrical bodies b and c. The thickness of the insulating sheath b / c is 0.2 to 0.4 m including the tubular body c and the inner surface insulator b.
/ M.

5) The built-in power source of the handle portion may be a rechargeable battery instead of a dry battery. A charging device for the rechargeable battery can be set as a set.

The power supply to the energization heating element 2a of the heater head B and the drive unit (motor) of the shaver head C may be DC or AC, or may be an external power supply such as a commercial power supply.

In this case, a connector portion for connecting to an external power source or a converter for converting a voltage and / or a current input from the external power source can be built in the handle portion A side. It is possible to support both the method of supplying power to the electric heating element 2a with a built-in battery and the method of using an external power source. The converter may be provided separately from the device.

In the example of FIG. 20, a connector 4 for inserting an output plug (not shown) from an AC adapter (not shown) of an external power source is provided inside the handle cylinder cover 1c instead of the conductive coil spring 1f. It is a thing. By electrically connecting one electrode of the connector 4 to the tube lid 1c and electrically connecting the other electrode to the electrode body 1e by an appropriate method, it is possible to supply power to the energization heating element 2a by an external power supply method. Since the handle portion A does not need a space for accommodating the battery, the length thereof can be shortened to further reduce the size of the device. Also one
One cylindrical lid 1c is provided with both the conductive coil spring 1f for the battery and the connector 4 for the external power source, and an appropriate method, for example, a pseudo battery provided only with the center electrode body is used together, and the internal battery method and the external method are used. It can also be compatible with both power supply systems.

6) Needless to say, the electric blade mechanism as the blade means of the shaver head C is not limited to the structure of the illustrated example, and even if it is composed of a fixed blade and a movable blade, the movable blade is a straight line. It may be reciprocally driven.

The drive unit (motor) of the electric blade mechanism may be provided on the grip portion A (apparatus body) side.

The comb tooth portion 5 may not be provided. The blade means may be a fixed razor blade.

7) It is also possible to construct a shaver single-function hair treatment tool provided with the comb tooth portion and the electric hair cutting mechanism as in the above example, which cuts the hair combed into the comb tooth portion.

Also in this case, the comb tooth portion is detachable from the body treatment tool body for portability and cleaning and replacement of the comb tooth portion.
