FIG. 3B shows a perspective view 910 of the hairbrush. FIG. 4 shows a six-view view of the hairbrush according to the first embodiment. FIGS. 4A to 4F show a front view, a rear view, a plan view, a bottom view, a left side view, and a right side view, respectively. FIG. 5 is a diagram for explaining a method of fitting the head portion 70 and the grip portion 72 in the hairbrush according to the first embodiment. FIG. 6 is a perspective view 920 schematically showing the head portion 70 and the grip portion 72 in the hairbrush according to the first embodiment.

The hairbrush according to the first embodiment includes a grip portion 72 as a portion to be gripped by a user, and a head portion 70 connected to a predetermined end portion 73 in the longitudinal direction of the grip portion 72. Here, it is preferable that the heat transfer body 40 is arranged in the head portion 70, and the grip portion 72 and the head portion 70 have a substantially linear appearance at the time of use. Further, the grip portion 72 and the head portion 70 may exhibit an appearance of being connected at a predetermined angle. The head portion 70 includes a heat transfer body 40 that transfers heat to the hair, and the heat transfer body 40 has a plurality of rising pin shapes (bristle 41, 32, 42). Further, the head portion 70 includes a straightening vane (guide rib) 71. As shown in FIGS. 2 and 3, it is preferable that a plurality of straightening vanes 71 are arranged over a surface other than the heat transfer body 40 of the elliptical columnar head portion 70. It is preferable that the straightening plate 71 can adjust the traveling direction of the hair. The heat transfer body 40 is preferably equipped with a heater (not shown) inside. The material of the heat transfer body may be any material as long as it has good thermal conductivity, and is preferably a metal such as stainless steel and an aluminum alloy. The heat transfer body can be formed of other metals, and the heat transfer body is not limited to the above metal materials.

A power cord 91 is connected to another end of the grip 72 that faces a predetermined end 73. It is preferable that there is a heater (not shown) inside the head portion 70. Further, the grip portion 72 may be configured to include the heater, and it is preferable that the heat transfer body 40 is equipped with the heater inside. The material of the heat transfer body may be any material as long as it has good thermal conductivity. The shape of the brush surface is preferably a flat surface in the xy plane. The shape of the brush surface may be convex or concave in the xz plane.

Further, as shown in FIG. 4A, the grip portion 72 preferably includes a switch 110 and an operation portion 120. As a result, the switch 110 provided on the grip portion 72 can be pressed after inserting the plug (not shown) provided at the tip of the power cord 91 into the outlet. Further, the temperature can be set to a desired temperature by the operation unit 120. The set temperature of the operation unit 120 is not particularly limited, but it is preferable that the operation unit 120 is configured so that the temperature of the heater (not shown) can be selected from a combination of a plurality of set temperatures. As an example, the operating unit 120 is preferably configured so that the temperature of the heater can be selected from 100 ° C, 120 ° C, 140 ° C, 160 ° C, 180 ° C, and 200 ° C.

As a result, after the heater reaches a desired temperature, the grip portion 72 can be held by hand and the head portion 70 can be applied to the hair. As a result, the heat transfer pin comes into contact with the hair, and heat is suitably transferred to the hair. Hair setting is completed when the hair cools naturally.

When the hairbrush iron according to the first embodiment is used in a state where the hair is wet, it is possible to set the hair while drying it with a heated heat transfer pin. After the operation is completed, when the switch 110 is turned off and the energization is turned off, the heat generation of the heater is stopped, and when left unattended, the head portion 70 is dissipated to room temperature.

Next, a method of fitting (assembling method) between the head portion 70 and the grip portion 72 in the hairbrush according to the first embodiment will be described with reference to FIG. As shown in FIG. 5, here, a case where the head portion 70 and the grip portion 72 are separate bodies will be described.

First, as shown in FIG. 5A, the longitudinal direction of the head portion 70 is directed toward the predetermined end portion 73 in the longitudinal direction of the grip portion 72 facing the predetermined end portion 77 in the longitudinal direction of the head portion 70. The predetermined end portion 77 in the above is brought closer.

Next, as shown in FIG. 5B, the insertion portion 75 of the head portion 70 is inserted into the fitting portion 74 of the grip portion 72.

Next, as shown in FIG. 5 (c), the insertion portion 75 of the head portion 70 is inserted (incorporated) to the depth of the fitting portion 74 of the grip portion 72. As a result, the first gap portion 76 is provided between the predetermined end portion 77 of the head portion 70 and the predetermined end portion 73 of the grip portion 72. In this case, the fitting portion 74 may include an adjusting portion (not shown) such as a positioning rib. Thereby, the gap width of the first gap portion 76 can be suitably adjusted.

Further, it is preferable that the head portion 70 and the grip portion 72 are fixed by the fixing portion 78 after the insertion portion 75 of the head portion 70 is inserted to the depth of the fitting portion 74 of the grip portion 72. The head portion 70 and the grip portion 72 are fixed by the fixing portion 78 by, for example, screwing into the inside of the grip portion 72 from a screw hole provided on the surface of the grip portion 72 toward the lateral side of the grip portion 72. This is done by inserting a fixing portion 78 such as. In this case, after tightening the screws by deepening the screw holes, as shown in FIG. 5 (c), the fixing portion 78 such as a screw is inserted into the grip portion 72, whereby the fixing portion 78 is inserted into the fixing portion 78. It becomes difficult to touch the fingertips. As a result, even if the fixed portion 78 becomes hot due to the influence of the heater provided on the head portion 70, it becomes difficult for the fingertip to touch the hot fixed portion 78.

The gap width of the first gap portion 76 provided between the predetermined end portion 77 of the head portion 70 and the predetermined end portion 73 of the grip portion 72 in the hairbrush according to the first embodiment is 0.2 mm or more.

Here, in a conventional hairbrush, a separate component is provided between a predetermined end portion in the longitudinal direction of the head portion and a predetermined end portion in the longitudinal direction of the grip portion facing the predetermined end portion in the longitudinal direction of the head portion. Was provided. Then, the predetermined end portion of the head portion and the predetermined end portion in the longitudinal direction of another component facing the predetermined end portion of the head portion were screwed and tightly tightened along the longitudinal direction of the hairbrush. As a result, it becomes difficult for hair to enter a gap between the head portion and the grip portion in the longitudinal direction, and when the hair enters and gets caught, the hair does not easily come off from between the head portion and the grip portion, or it becomes difficult to come off. I was preventing it from happening. However, when another component is provided between the predetermined end of the head portion and the predetermined end of the grip portion, the separate component is provided between the predetermined end of the head portion and the predetermined end of the grip portion. There is a problem that the configuration of the hairbrush becomes complicated because another part is provided. Further, since the separate parts are provided, there is a problem that the manufacturing process of the hairbrush is increased and the production efficiency of the hairbrush is lowered.

On the other hand, in the hairbrush according to the first embodiment, as shown in the six views of FIG. 4, the outer peripheral surface of the head portion 70 and the outer peripheral surface of the grip portion 72 substantially coincide with each other. Therefore, if a separate component is not provided, the predetermined end portion 77 of the head portion 70 and the predetermined end portion 73 of the grip portion 72 cannot be screwed along the longitudinal direction of the hairbrush. Further, as described above, the fixing portion 78 such as a screw is inserted into the grip portion 72 from the screw hole provided on the surface of the grip portion 72 toward the lateral side of the grip portion 72. When the head portion 70 and the grip portion 72 are fixed, the fixing force does not work along the longitudinal direction of the hairbrush. Therefore, it is difficult to fix the hairbrush tightly in the longitudinal direction, and a gap is created.

Therefore, in the hairbrush according to the first embodiment, the gap width of the first gap portion 76 is set to 0.2 mm or more so that the gap width is not too narrow. As a result, when the hair is set by the hairbrush iron, the hair may get stuck in the first gap 76 and get caught, so that the hair may not come out of the first gap 76 or may be difficult to come out. Can be reduced. In addition, it is possible to prevent the usability of the hairbrush from being reduced. In other words, the usability of the hairbrush can be improved.

Further, since it is only necessary to provide the first gap portion 76 having a predetermined gap width between the predetermined end portion 77 of the head portion 70 and the predetermined end portion 73 of the grip portion 72, another component is provided. There is no need. Therefore, according to the hairbrush according to the first embodiment, damage to the hair can be reduced by a simple configuration. Further, since the hairbrush has a simple structure and does not need to be provided with a separate part, the production efficiency of the hairbrush can be improved. In particular, when the first gap portion 76 is provided by directly connecting (fitting) the predetermined end portion 77 of the head portion 70 and the predetermined end portion 73 of the grip portion 72, the production efficiency of the hairbrush is improved. be able to.

Further, the gap width of the first gap portion 76 is preferably 0.7 mm or less. When the gap width of the first gap portion 76 is 0.7 mm or less, the first gap portion 76 is not too conspicuous, and it is possible to prevent the aesthetic appearance from being impaired.

Further, the gap width of the first gap portion 76 is preferably 0.5 mm or more. When the gap width of the first gap 76 is 0.5 mm or more, even if the hair enters the first gap 76, the hair can be more easily pulled out from the first gap 76, so that the hair can be removed. Damage can be further reduced.

Next, the head portion 70 and the grip portion 72 in the hairbrush according to the first embodiment will be described in more detail with reference to FIG. As shown in FIG. 6, a case where the hairbrush has a cylindrical shape will be described here.

As shown in FIG. 6, the outer peripheral surface of the head portion 70 and the outer peripheral surface of the grip portion 72 substantially coincide with each other, and the first gap portion 76 is provided, for example, over the entire circumference of the hairbrush cylinder. .. Here, the head portion 70 and the grip portion 72 are provided so that the first gap portion 76 having a gap width of 0.2 mm or more is provided over the entire circumference of the connection portion between the head portion 70 and the grip portion 72. Is connected and fixed. As a result, even if the hair enters any position of the connection portion between the head portion 70 and the grip portion 72, the connection portion is the first gap portion 76 having a gap width of 0.2 mm or more. It is possible to further reduce the possibility that the hair will not come out from the gap portion 76 of 1. As a result, damage to the hair can be further reduced.

Further, the heat transfer body 40 may be made of a metal material, and the grip portion 72 may be made of a resin material. For example, in FIG. 6, the heat transfer body 40 is made of a metal material, and the portion of the head portion 70 excluding the heat transfer body 40 and the grip portion 72 are made of a resin material. In this case, a predetermined end portion 77 made of a metal material in the longitudinal direction (y-axis direction) of the heat transfer body 40 and a predetermined end portion 77 made of a resin material in the longitudinal direction (y-axis direction) of the grip portion 72. Will be connected to the end 73 of the.

Here, the predetermined end portion 77 in the longitudinal direction of the portion of the head portion 70 excluding the heat transfer body 40 and the predetermined end portion 73 on the first surface 72a side in the longitudinal direction of the grip portion 72 are both. It is a resin material. Therefore, for example, by forming these ends from the same resin material, these ends can be connected without a gap.

However, in the heat transfer body 40, the predetermined end portion 77 made of a metal material and the predetermined end portion 73 made of a resin material on the second surface 72b side of the grip portion 72 are not compatible with each other. It is composed of different materials. Therefore, it is not easy to connect these ends without a gap. Here, for example, it is assumed that there is a gap having a minute gap width of less than 0.2 mm between these ends, and hair has entered the gap. In this case, there is a possibility that the hair may be damaged, for example, the hair may be cut due to the hair getting caught in the gap or being stuck in the gap.

On the other hand, in the present embodiment, there is a gap width of 0.2 mm or more between the predetermined end portion 77 of the heat transfer body 40 and the predetermined end portion 73 on the side of at least the second surface 72b of the grip portion 72. A first gap 76 is provided. As a result, even when the hair enters the first gap portion 76, the hair can be easily pulled out from the first gap portion 76, so that damage to the hair can be reduced.

[Embodiment 2]
In the hairbrush according to the first embodiment, the head portion 70 and the grip portion 72 are completely separate bodies. However, like the hairbrush according to the second embodiment, the head portion 170 and the grip portion 172 may be integrated on the back surface of the hairbrush, and only the heat transfer body 140 may be a separate body.

Hereinafter, the hairbrush according to the second embodiment will be described with reference to FIG. 7. For convenience of explanation, the same reference numerals are given to the members having the same functions as the members described in the first embodiment, and the description thereof will be omitted.

FIG. 7 is a perspective view 930 schematically showing the hairbrush according to the second embodiment. In the hairbrush according to the second embodiment, the head portion 170 and the grip portion 172 are integrated (integrally molded) on the back surface (first surface 910a) of the hairbrush, and only the heat transfer body 140 is a separate body. It has become. Further, the heat transfer body 140 is provided on the front surface of the head portion 170 (the second surface 910b opposite to the first surface 910a). As described above, the hairbrush is more aesthetically pleasing because only the heat transfer body 140 is a separate body.

Here, there is a gap of 0.2 mm or more between the predetermined end 177 in the longitudinal direction of the heat transfer body 140 and the predetermined end 173 in the longitudinal direction of the grip portion 172 facing the predetermined end 177. A second gap 176 having a width is provided. As described above, the gap width of the second gap portion 176 is not too narrow. Therefore, when the hair is set by the hairbrush iron, the hair may get stuck in the second gap 176 and get caught, so that the hair may not come off from between the head part and the grip part, or it may be difficult to come off. The sex can be reduced. In addition, it is possible to prevent the usability of the hairbrush from being reduced. In other words, the usability of the hairbrush can be improved.

Further, the gap width of the second gap portion 176 is preferably 0.7 mm or less. When the gap width of the second gap portion 176 is 0.7 mm or less, the second gap portion 176 is not too conspicuous, and it is possible to prevent the aesthetic appearance from being impaired.

Further, the gap width of the second gap portion 176 is preferably 0.5 mm or more. Since the gap width of the second gap 176 is 0.5 mm or more, even if the hair enters the second gap 176, the hair can be more easily pulled out from the second gap 176, so that the hair can be removed. Damage can be further reduced.
