Description

Electric hair treatment device

The present invention relates to an electric hair treatment device, and particularly to an electric hair treatment device suitable for treating pubic hair and the like.

It is not preferable to use a knife such as scissors or a razor for the treatment of body hair, especially pubic hair, because the tip of the hair is cut off by the knife and becomes sharp, and when it touches the tip, it receives irritation such as tingling. For this reason, as an electric body hair treatment device used for treating waste hair such as pubic hair, a type that burns off by heat using an energizing heating element such as a nichrome wire has been conventionally proposed (for example, Patent Documents). See 1, Patent Document 2.)

In the electric hair treatment device of the type that uses an energizing heating element such as nichrome wire and burns off unwanted hair such as pubic hair with heat as described above, the tip of the cut hair is different from the case where it is cut with a knife. It does not become sharp and does not receive irritation such as tingling when it touches the tip of the hair.

Hereinafter, the electric hair treatment device according to the embodiment will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the overall configuration of the electric hair treatment device 100 according to the embodiment, FIG. 2 is a plan view of the electric hair treatment device 100, and FIG. 3 is a side view of the electric hair treatment device 100. As shown in these figures, the electric hair treatment device 100 houses an electronic circuit (not shown) inside, and has a case portion 101 used as a grip portion when the outer shell is held and operated by hand. It is equipped. The case portion 101 is made of resin and has a size that can be gripped with one hand. In the example of the present embodiment, as shown in FIG. 2, the length A in the longitudinal direction is about 110 mm and the length B in the lateral direction is B. It is about 50 mm, and as shown in FIG. 3, the thickness D is about 20 mm.

As the electronic circuit, a circuit for supplying electric power to the heating element 105, which will be described later, a circuit for lighting an LED lamp 111 or the like indicating a usage state, and a circuit for automatically stopping the power supply when the usage state continues for a certain period of time. There are circuits for doing this, batteries for supplying power, and so on. Reference numeral 110 shown in FIG. 2 and the like is a main switch, and 112 is a rotation of the first comb tooth 103 and the second comb tooth 104 of the hair burn-off portion 102, which will be described later, as shown by the arrows in FIG. It is an open / close button for opening.

A body hair burn-off portion 102 is provided at the tip portion (upper end portion in FIG. 2) in the longitudinal direction of the case portion 101. The body hair burn-off portion 102 is provided with a plurality of first comb teeth 103 extending linearly from the first side surface (lower side surface) 101a of the case portion 101 toward the tip end direction (upper direction in FIG. 2). There is.

Further, the body hair burn-off portion 102 has a first side surface (upper side surface) 101b facing the first side surface 101a of the case portion 101 toward the tip end direction (upper side in FIG. 2) and first. A plurality of second comb teeth 104 that are curved and extend outward toward the comb teeth 103 so as to be convex (rake-shaped) are provided.

As shown in FIG. 4, the distance between the first comb teeth 103 and the distance between the second comb teeth 104 is set wider than the distance between the second comb teeth 104. As for the number of comb teeth, the number of the second comb teeth 104 is set to be smaller than the number of the first comb teeth 103. In the present embodiment, the number of the first comb teeth 103 is 14, and the number of the second comb teeth 104 is 10. The distance between the first comb teeth 103 is 1 mm, and the distance between the second comb teeth 104 is 2 mm.

As shown in FIG. 4, when the hair-burning portion 102 is viewed from the tip side, a gap 106 is provided between the first comb tooth 103 and the second comb tooth 104, and the depth of this gap is provided. A linear heating element 105 made of a nichrome wire or the like is provided on the side.

FIG. 5 schematically shows a case where the positional relationship between the first comb tooth 103, the second comb tooth 104, the heating element 105, and the interval 106 is viewed from the side. As shown in FIG. 5, the first comb tooth 103 is linear, and the second comb tooth 104 is convex (bearer-shaped) outward in the direction of the first comb tooth 103. Due to the curved shape, the above-mentioned interval 106 is formed at a position closer to the first comb tooth 103 side from the middle between the first comb tooth 103 and the second comb tooth 104. Therefore, the heating element 105 is also provided at a position closer to the first comb tooth 103 side from the middle between the first comb tooth 103 and the second comb tooth 104. The width d1 of the interval 106 shown in FIG. 5 is about 5 mm.

The first comb tooth 103 and the second comb tooth 104 are integrally formed with a resin member constituting the outer shell of the hair burn-off portion 102, and the left portion in FIG. 2 is the left portion with respect to the case portion 101. It is rotatably locked. Then, by pressing the open / close button 112 of the case portion 101, the resin member including the first comb tooth 103 and the second comb tooth 104 is opened as shown by the arrow in FIG. 2 (indicated by the dotted line in FIG. 2). , The heating element 105 disposed inside can be exposed and the surrounding area can be cleaned.

As a basic usage mode of the electric hair treatment device 100, by moving the first comb tooth 103 along the skin, body hair such as pubic hair is raised, and the raised body hair is moved to the second comb tooth 104. It is supported between them and burned off by a linear heating element provided between the first comb tooth 103 and the second comb tooth 104. Therefore, it is possible to efficiently perform hair treatment by holding the electric hair treatment device 100 with one hand without using both hands, and it can be suitably used even when a man treats waste hair such as pubic hair. can. In the case of pubic hair and the like, there are many curly hairs instead of straight hairs, and it is necessary to efficiently burn off these curly hairs. Further, since the heating element 105 is used, it is necessary to ensure the safety against heat so that the heating element 105 and the skin do not come too close to each other to prevent burns.

The electric hair treatment device 100 can also be used by holding the tip side of the hair with one hand and holding the electric hair treatment device 100 with the other hand and applying it to the hair for treatment. It is also possible to apply the electric hair treatment device 100 to the skin from the vertical direction and slide the tip side of the second comb tooth 104 along the skin to treat the hair.

The reason why the number and spacing of the first comb teeth 103 and the number and spacing of the second comb teeth 104 are as described above will be described below. As described above, as a basic usage mode of the electric hair treatment device 100, the first comb tooth 103 is moved along the skin to cause hair such as pubic hair. The distance between the comb teeth 103 of 1 needs to be sufficient to ensure safety against heat, and from this viewpoint, it is preferably about 1 mm to 1.1 mm. In this case, in the present embodiment, the number of the first comb teeth 103 is preferably 14 or 13. In the present embodiment, as described above, the distance between the first comb teeth 103 is 1 mm and the number of the first comb teeth 103 is 14.

In order to find out the optimum number and spacing of the second comb teeth 104 with respect to the number and spacing of the first comb teeth 103, the number and spacing of the second comb teeth 104 are 14 and the spacing is 1 mm (first). (Same as the comb teeth 103), 12 hairs with an interval of 1.4 mm, 10 teeth with an interval of 2 mm, and 8 teeth with an interval of 2.9 mm. Two points of safety against heat were investigated.

Table 1 shows the results of the above survey. The evaluations in Table 1 indicate that the evaluations are highest in the order of ×, Δ, and ◯.

As shown in Table 1, when the number and spacing of the second comb teeth 104 are 14 which are the same as those of the first comb teeth 103 and the spacing is 1 mm, the spacing between the second comb teeth 104 is narrow. The body hair raised by the comb tooth 103 of 1 interferes with the second comb tooth 104, making it difficult to enter between the second comb teeth 104, and the evaluation of the ease of plucking and raising the body hair is low. became. In this case, the safety against heat was good.

As shown in Table 1, when the number and spacing of the second comb teeth 104 are 12, 1.4 mm, the hair is easier to plow and start up than when the above 14 teeth and spacing are 1 mm. There was an improvement in ease, but not enough. The heat safety was good.

As shown in Table 1, when the number and spacing of the second comb teeth 104 were 10 and 2 mm, the ease of plucking and raising the body hair was better than in the above two cases. In addition, the safety against heat was also good.

As shown in Table 1, when the number and spacing of the second comb teeth 104 are 8 and 2.9 mm, the ease of plucking and raising the body hair is better than that of the first two cases described above. Met. However, since the distance between the second comb teeth 104 is wide, the soft or loose parts of the skin tend to bite between the comb teeth, and the person may feel heat, and the safety against heat is evaluated as Δ. rice field.

As described above, when the number and spacing of the second comb teeth 104 are the same as those of the first comb teeth 103, the spacing between the second comb teeth 104 is narrow, so the first comb teeth 103 are used for starting up. The body hair interfered with the second comb tooth 104, making it difficult for the body hair to enter between the second comb teeth 104, resulting in poor ease of plucking and rising of the body hair. On the other hand, if the number of the second comb teeth 104 is reduced and the interval is widened too much, a particularly soft part of the skin tends to bite between the comb teeth, and heat may be felt, which is preferable in terms of heat safety. The result was that there was no such thing.

Therefore, in the present embodiment, the number and spacing of the second comb teeth 104 are set to 10 and 2 mm. As a result, the hair is easy to plow and start up, and safety against heat can be ensured. Further, in the present embodiment, as shown in FIG. 5, the heating element 105 is also provided at a position closer to the first comb tooth 103 side from the middle between the first comb tooth 103 and the second comb tooth 104. ing. That is, since the comb teeth are arranged more densely and the heating element 105 is arranged closer to the side where the distance between the comb teeth is narrower, the safety against heat can be ensured more reliably. When the number of the first comb teeth 103 was set to 13 and the interval was set to 1.1 mm, the same result as in the case where the number of the first comb teeth 103 was set to 14 was obtained. That is, also in this case, it is preferable that the number of the second comb teeth 104 is 10 and the interval is 2 mm. The ratio of the interval between the second comb teeth 104 to the interval between the first comb teeth 103 is preferably about 1.8 to 2.0 times.
