However, in the prior art as described above, for example, although a hair brush can set a hairstyle once, there is a problem that heat is not easily transmitted to the hair when the hair cannot be grasped well. On the other hand, when the number of needles of the brush is excessively increased, there is a problem that the hair is tangled and does not fall off, thereby causing great damage to the hair.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to realize that hair is efficiently grasped by the bristles and that the setting force of the hair is improved.

In order to solve the above technical problem, the hair brush of the present invention includes a head portion, and a setting portion made of a thermally conductive body that transmits heat to hair is disposed on a first surface of the head portion, and the setting portion includes A plurality of bristles whose vertical cross-section in the height direction is an elliptical shape having a long axis and a short axis, and the short axis is arranged to have an angle that rotates in one direction with respect to an axis in the longitudinal direction of the setting portion. The center of the cross section of the bristles in the first surface is geometrically disposed in the first surface, and the geometrical configuration is a configuration in which an arrangement along a part of the spiral in the first surface is arranged.

According to the present invention, based on the above-mentioned configuration, the use of a region having a large curvature of the ellipse has the effect of being able to bend the hair.

According to one aspect of the present invention, the hair can be efficiently grasped by the bristles, and the setting force of the hair can be improved.

FIG. 1 is a schematic view showing the arrangement schemes 100 and 110 of bristles of a conventional brush. In FIG. 1, the appearance of the brush is not shown, and the arrangement of the bristles viewed from the direction facing the brush surface (xy plane) (z-axis direction perpendicular to the xy plane) is schematically shown. As shown in FIG. 1 (a), in a general brush, the bristles 10 are arranged in a grid shape. In this configuration, hair friction is generated in a certain direction 101 in the xy plane. In other prior art, as shown in FIG. 1 (b), the bristles 11 are arranged to be different from each other (Patent Document 1).

Patent Document 1 (Public Application No. 3206808) proposes a combination of a brush and an ion clip. The brush of Patent Document 1 has the convenience of combing the hair without having to comb it once. The bristles (needle) are arranged in series in the xy plane opposite to the y axis (FIG. 3 (a)). Although this invention is used in a straight line, when such an array structure is used, the hair is rubbed in a certain direction 111 in the xy plane. Therefore, it is necessary to increase the number of bristles or to set the size of each bristle to be large. In Patent Document 1, there is almost no gap between the bristles and the bristles (FIG. 3 (a)), and the hair is considered to be damaged by strong friction.

Furthermore, Patent Document 2 proposes bristles that conform to the curvature of a human head, and it is also conceivable to design bristles based on this shape. However, although it is considered to have a suitable feeling for the head, for example, the part with long hair and separated from the head may feel worse in use. Although Patent Document 3 proposes a hair dryer that improves grip by animal hair, it cannot uniformly and efficiently transfer heat.

The need for a setting brush that increases the grip of the hair and efficiently transmits heat to the hair in a short time is expected.

[First embodiment]
Hereinafter, one embodiment of the present invention will be described in detail.

The hair brush of the present invention has a head for combing hair, and the head has a setting part for setting the hair. In a preferred embodiment, the setting portion is disposed on one side of the head. The head is composed of a thermal conductor that transfers heat to the hair, and has a plurality of needle shapes (bristles) standing upright (z-axis direction) with respect to the surface (xy plane) (bristle surface) of the setting portion.

FIG. 2 is a schematic view showing a geometrical arrangement of bristles of a bristle brush of the present invention. Figures 2 (a) to (c) do not show the appearance of the brush, but only schematically show the geometry of the bristles 20, 21, and 22 seen from the face of the brush (in the z-axis direction perpendicular to the xy plane).地 Configuration.

In a preferred embodiment of the present invention, the center of each of the xy planes of the needle-shaped bristles 20, 21, and 22 (see FIG. 3 (b) (i)) is arranged in a fixed geometric shape. . The preferred geometric shape is a two-dimensional curve, and more preferably a spiral (vortex). In a preferred embodiment of the present invention, it is characterized in that the bristles are arranged as part of a spiral along the xy plane.

Here, "a part of a spiral" refers to a part of a spiral included in a region constituting a setting portion in a conceptually expanded xy plane. It is preferable that a plurality of trajectories configured as a spiral are generated in a spiral having a pitch of an xy plane constituting the setting portion. For example, in FIG. 2 (a), it can be confirmed that at least 11 trajectories 202 of the spiral are generated in the xy plane coordinates constituting the setting section. In FIG. 2 (b), it can be confirmed that at least 11 helical trajectories 212 are generated in the xy plane coordinates constituting the setting section. In FIG. 2 (c), it can be confirmed that at least 12 spiral trajectories 222 are generated in the xy-plane coordinates constituting the setting section, and it can be confirmed that at least 16 spiral trajectories 223 are generated. The arrangement in which the bristles are arranged along a part of a spiral spiral in the xy plane is called a "spiral arrangement" or "spiral arrangement". The scheme of the spiral is not limited to an algebraic spiral such as the Archimedes spiral, and a logarithmic spiral can be used. In a preferred embodiment, a Fibonacci spiral can be used. Various parameters such as the initial radius and pitch of the spiral can be arbitrarily set.

In a preferred embodiment, an Archimedean spiral (algebraic spiral) that can be described with polar coordinates r = aθ can be used. For example, in the trajectory 223 of FIG. 2 (c), when the parameter a is 0.017 and θ = t × 360, 16 trajectories with t of 20 to 35 are generated. In the trajectory 223 of FIG. 2 (c), when the parameter a is 0.02 and θ = −t × 360, twelve trajectories of 36 to 47 are generated.

In the configuration of the present invention in which the xy plane bristles 20, 21, and 22 are arranged in a spiral shape, the metal needles (bristles) 20, 21, and 22 are evenly arranged. Thereby, the metal needles (bristles) 20, 21, 22 make sure contact with the hair to be rubbed independently of the position or direction 201, 211 of the hair entering (refer to FIG. 2 (a), (b)). As a result, the hair is caught by the metal needles (bristles) 20, 21, and 22, and the setting force of the hair can be improved.

As shown in FIGS. 2 (a) and 2 (b), the direction of the spiral may be the direction of the trajectory 202 or the direction of the trajectory 212. As shown in FIG. 2 (c), it is preferable to arrange the bristles 22 at the intersection of the combination of the trajectories 222 and 223 based on the spirals in two directions. Because the hair brush is used for the entire hair, it is assumed that the user of the right-handed person and the user of the left-handed person cannot determine the direction of the hair according to the use situation. With the configuration shown in FIG. 2 (c), hair entering from any direction will be caught by the bristles 22, and the setting force of the hair can be increased. The plurality of needles are configured to follow a first trajectory in one spiral, and other plurality of needles may also be configured to follow a second trajectory in the spiral (the second trajectory is adjacent to the first trajectory).

In other preferred embodiments, the brush is composed of a grip and a head, and the head may be an elliptical columnar shape having a height in the long axis direction of the brush. When an elliptical columnar head is used, it is preferable that the head be disposed on the surface of the elliptical column.

As shown in FIG. 3, the cross-sectional shape in the xy plane of the bristles is preferably an elliptical shape (see FIG. 3 (b) (i)). In Fig. 3 (b) (i), an axis parallel to the x-axis passing through the center is a long axis, and an axis parallel to the y-axis passing through the center is a short axis. When the long axis and the short axis are equal (see FIG. 3 (b) (ii)), the cross-sectional shape of the bristles is circular. In the present specification, a circular shape is an aspect of an elliptical shape.

When bristling with a brush, the hair passes through the gap as much as possible. For example, in Patent Document 1 and the like, when the brush is moved in a specific direction (a direction opposite to 111), most of the hair may be wiped. In this case, the bristles 11 of the brush cannot grasp the hair, and because the hair interposed between the bristles 11 cannot transfer heat, the hair cannot be set to a desired shape. In Patent Document 1 for suppressing the brushing of hair, a method of increasing the density of the bristles 11 by a method of setting the thickness of the heat transfer needles to be thick, increasing the number of heat transfer needles, and the like is implemented. However, when the density of the metal bristles is increased indiscriminately, the gap in the y-axis direction between the bristles becomes narrower. As a result, the friction with the hair becomes stronger, the hair is damaged, and it becomes difficult for the hair to enter the needles.

In contrast, the gap in the y-axis direction between the bristles arranged spirally in the present invention does not become narrower than the gap in Patent Document 1. With this configuration, the hair can be set reliably while reducing the damage to the hair as compared with the conventional bristles.
