Description

The present invention relates to a brush attachment specialized for adding volume, firmness, and shine to hair, and a hair dryer equipped with the brush attachment.

A hairbrush, which has a brush section made of flexible plastic or rubber material and has multiple bristles connected to a handle, can be placed against the roots of the hair and rotated in the same position to raise the roots, making it easy to style hair. After the roots have been raised, it is often used together with a hair dryer to dry the hair while combing it. When using both a hairbrush and a hair dryer, the hairbrush needs to be rotated many times, and women with long hair in particular have to move the hairbrush over a wide area, which puts a lot of strain on both hands. For this reason, a hairbrush has been devised that allows one to easily style their hair with one hand while drying it with a hair dryer.

For example, the invention in Patent Document 1 discloses an "improved hairbrush structure that includes a hairbrush handle connected to a tubular body containing a plurality of bristles, the tubular body being perforated to allow hot air generated by a hair dryer to pass therethrough, thereby facilitating the action of styling and drying hair."

The invention in Patent Document 2 discloses a hairbrush that "has a grip (1) for gripping the main body and a brush section (2) at the end of the grip, the brush section (2) having a metal tubular body (3) with numerous ventilation holes (5) formed therein, with numerous bristles (4) protruding from the outer periphery of the tubular body (3), and a connection port for a hair dryer formed at the tip of the tubular body (3)."

These hair brushes with hair dryers have a tubular body (brush section) in which hair strands are attached, and hot air from the dryer connected to the brush section is sprayed out from inside the brush section, making it easy to style your hair with one hand while drying it.

However, with these conventional hair brushes with hair dryers, the brush part had to be switched depending on the purpose, such as lifting the roots of the hair (hereinafter also referred to as "root lifting"), combing the hair by placing a strand of hair between the hair (hereinafter also referred to as "combing"), or smoothing the surface of the hair (hereinafter also referred to as "styling"). In addition, the hot air from the hair dryer was emitted in a wide range of directions, which dispersed the direction of the hot air, making it inefficient for brushing and causing problems such as heat building up around the scalp and damaging the hair.

The brush attachment of the present invention allows you to lift the roots, comb, and style your hair with a single brush, so you can give your hair volume, firmness, and shine without having to switch brush parts depending on the purpose. In addition, by limiting the direction of the air from the dryer, the hot air hits the scalp and hair you are brushing at a pinpoint, which reduces damage to the hair caused by heat building up in other parts of the scalp and hair, and allows for efficient brushing.

Specifically, the brush attachment of the present invention has a triangular brush section and three types of brushes with different purposes are installed on one side, so that it is possible to sequentially accomplish purposes such as "root lifting" by lifting the roots of the hair, "combing" by putting strands of hair between the hair and combing it, and "styling" by smoothing the surface of the hair. In other words, by using the three types of brushes in sequence within the rotation of the wrist, these purposes can be efficiently achieved all at once using only the brush attachment of the present invention.

By setting the airflow angle at 25-35°C and limiting the airflow direction so that the hot air hits the scalp and hair at a pinpoint while being brushed, it is possible to efficiently impart shine to the hair while minimizing damage to the hair. Furthermore, by optimizing the shape and angle of the hot air airflow direction adjustment piece, it is possible to minimize the burden on the hair and effectively impart volume, firmness, shine, etc. to the hair.

In addition, a hair dryer equipped with the brush attachment of the present invention uses a spring at the connection between the brush attachment and the dryer, which allows uniform tension to be applied to the hair, reducing the strain on the hair. In other words, the use of a spring eliminates excessive force and allows uniform tension to be applied to the hair.

Below, we will explain the embodiment and examples of the brush attachment according to the present invention and the hair dryer in which the brush attachment is attached to the hair dryer, with reference to the drawings. Note that the same reference numerals will be used for the same components throughout the drawings.

The brush attachment 3 according to the present invention is shown in Figures 5(a) and (b). The brush attachment 3 is connected to the attachment port 102 of a dryer 100 having an attachment port 102 at its tip, forming a hair dryer 1 according to the present invention (see Figures 1(a) and (b)). However, the hair dryer 1 shown in Figures 1(a) and (b) is equipped with a different type of brush attachment 3 than the brush attachment 3 shown in Figures 5(a) and (b).

The brush attachment 3 according to the present invention (see Figs. 5(a) and (b)) is composed of a brush section 20 and an attachment section 30 having a brush connection section 32 and a dryer connection section 36 connected to the rear end of the brush section 20.

[Brush section]
As shown in FIG. 2(a), the brush section 20 has a tubular body 10 having a front end and a rear end, and on its surface, an air vent 15 (see FIG. 3(a)) through which air can be blown from inside the tubular body 10, and a bristle band P (11P, 12P), and has a brush band B (11B, 12B) with a plurality of bristle bundles 22 planted in the bristle band P.

[Attachment part]
As described above, the attachment part 30 (see Figures 5(a) and (b)) has the brush connection part 32 and the dryer connection part 36, and the dryer connection part 36 is connected to the mounting port 102 of the dryer 100 to form the hair dryer 1 (see Figures 1(a) and 1(b)).

[Tubular body]
As shown in Fig. 3(b), the tubular body 10 constituting the brush part 20 has a cross section in the shape of an approximately isosceles triangle, and is composed of a first surface 11 and a second surface 12 that form opposing equilateral sides, and a third surface 13 that connects them. The first surface 11 and the second surface 12 are preferably curved surfaces that form a gentle curve in cross section, and the third surface 13 is preferably a substantially flat surface. As will be described in detail later, the first surface 11 and the second surface 12 of the tubular body 10 are preferably connected by a boundary surface 14 that forms a straight line or a gentle curve in cross section.

In this tubular body 10, as shown in FIG. 3(a), a vent band 150 and a flock band P (11P, 12P) in which one or more vents 15 are arranged from the tip to the rear end of the tubular body 10 are provided on the surfaces of the first surface 11 and the second surface 12, respectively. A wind direction adjustment piece 151 that adjusts the direction of the wind blown through the vents 15 is provided on the upper edge along the vent band 150 (see FIG. 2(a)). As described above, the first surface 11 and the second surface 12 are curved surfaces that draw a gentle curve in cross section, so a certain angle is created between the flat wind direction adjustment piece 151 attached to the upper edge of the vent band 150 and the first surface 11 or the second surface 12.

[Wind direction adjustment piece]
2(a), the attachment with a brush 3 according to the present invention is characterized in that the airflow direction adjustment piece 151 provided on the first surface 11 and the second surface 12 can be adjusted so that the angle between the first surface 11 and the second surface 12 is 25 degrees to 35 degrees with respect to the direction of the third surface 13. Alternatively, the airflow direction adjustment piece 151 may be fixed so that the angle between the first surface 11 and the second surface 12 is 25 degrees to 35 degrees with respect to the direction of the third surface 13. In other words, it is preferable that the constant angle between the airflow direction adjustment piece 151 and the first surface 11 or the second surface 12 is 25 degrees to 35 degrees.

As described above, it is effective to first bring the boundary surface 14 into contact with the head, then pass the brush band B (11B or 12B) over the hair and rotate it in approximately the same position to lift the roots, comb and/or style the hair in that order (see Fig. 5(a) and Fig. 1(a)). As described above, the brush attachment 3 of the present invention adjusts the air direction from inside the tubular body 10 with the air direction adjustment piece 151, so that the hot air sent from the dryer 100 can be directed precisely at the scalp and hair being brushed. This reduces damage to the hair caused by heat building up in other parts of the scalp and hair not being brushed.

In other words, by adjusting the angle of the airflow to 25-35 degrees and limiting the airflow direction so that it hits the scalp and hair as it is being brushed in a pinpoint manner, damage to the hair can be suppressed, and by optimizing the shape and angle of the airflow adjustment piece, the burden that the hot air places on the hair can be reduced to a minimum. At the same time, because the hot air can be directed in a pinpoint manner to the scalp and hair as it is being brushed, it is possible to efficiently give the hair volume, firmness, luster, etc.

[Hair transplant belt]
A plurality of ventilation hole bands 150 may be provided in the brush part 20. Accordingly, as shown in Fig. 4, a plurality of air direction adjustment pieces 151 covering the plurality of ventilation hole bands 150 may be attached to each of the first surface 11 and the second surface 12. Then, the same or different types of bristle bundles 22 may be planted in each bristle planting band P provided below and along each ventilation hole band 150 to form a plurality of brush bands B (11B, 11B, 12B, 12B).

[Hair base heat conduction band]
In addition, the first surface 11 and the second surface 12 of the tubular body 10 are preferably connected by an interface 14 that is straight or gently curved in cross section as shown in Fig. 3(b) and Fig. 2(b). It is preferable that an air vent band 150 is provided on the interface 14, which is disposed from the tip to the rear end of the tubular body 10, and a hair base heat conduction band 230 is provided covering the air vent band 150 and having a metal band 231 and a hair base heat conduction piece 23 made of a plastic or rubber material attached thereto (see Fig. 4 and Fig. 1(a)).

That is, the brush attachment 3 according to the present invention is characterized in that the hair base heat conductive piece 23 is heated via the metal band 231 by hot air blown through the ventilation band 150 provided on the boundary surface 14, as shown in FIG. 4.

As described above, it is preferable to first bring the boundary surface 14 into contact with the head, pass the brush band B (11B or 12B) over the hair, and rotate it in approximately the same position to sequentially raise the roots, comb and/or style the hair. When brushing with the brush attachment 3 according to the present invention, the hair roots can be raised by first bringing the hair base heat conductive piece 23 into contact with the head to heat the roots, and then the hair can be combed by inserting the hair bundles 22 between the hair using the brush bands 11B, 11B or brush bands 12B, 12B formed on the first surface 11 or second surface 12 of the tubular body 10 (see Fig. 5(a) and Fig. 2(a)).

As shown in FIG. 4, the brush attachment 3 of the present invention has a plurality of ventilation bands 150 arranged from the front end to the rear end of the tubular body 10 on the surfaces of the first surface 11 and the second surface 12 of the tubular body 10, and a hair planting band P is provided below each ventilation band 150 along the ventilation band 150. In FIG. 4, the brush bands 11B, 11B and the brush bands 12B, 12B, each having the same type of hair bundles 22 planted thereon, are attached to the first surface 11 and the second surface 12. For example, the brush band 11B has hair bundles 22 planted for hair styling, and the brush band 12B has hair bundles 22 planted for combing. In addition, the hair base heat conductive piece 23 of the hair base heat conductive band 230 provided on the boundary surface 14 exerts the function of raising the roots as described above.

The brush attachment 3 of the present invention can first perform a root raising process to raise the roots of the hair using the hair base heat conductive piece 23, then a combing process to comb the hair using the brush band 12B on the second surface 12, and finally a hair styling process to style the hair using the brush band 11B on the first surface 11. In other words, a series of processes can be performed with a single brush to reproduce volume, firmness, and shine without switching brush parts depending on the purpose of root raising, combing, and hair styling. In addition, the air direction from the dryer is limited so that it hits the scalp and hair being brushed in a pinpoint manner, which reduces damage to the hair caused by heat being trapped in other parts of the scalp and hair, and efficiently gives the hair volume, firmness, shine, etc.

In addition, the brush bands 11B, 11B' or brush bands 12B, 12B' may be formed with different types of bristles 22 planted on the bristles 11P, 11P or bristles 12P, 12P provided on each of the first and second surfaces 11 and 12 (see Fig. 8 and Fig. 6(a)). That is, the bristles 22 for combing and the bristles 22 for hair styling may be planted on the bristles 11P, 11P' in order from the boundary surface 14 side, and the bristles 22 for combing and the bristles 22 for hair styling may be planted on the bristles 12P, 12P' in order from the boundary surface 14 side. The brush attachment 3 of this invention will be described in detail in the following examples.

[Attachment part]
As shown in Fig. 6(a), in the brush attachment 3 of the present invention, the attachment part 30 is composed of a brush connection part 32 connected to the rear end of the tubular body 10, a dryer connection part 36 connected to the mounting port 52 of the dryer 50, and an elastic part 34 that fits into the brush connection part 32 and the dryer connection part 36 to connect them. As shown in Fig. 6(b), a perspective view of the back side of the brush attachment 3, the third surface 13 is preferably flat so that it is convenient to place it on a shelf or a table, and a placement part 361 that is flush with the third surface 13 is preferably provided on the third surface 13 side of the dryer connection part 36 to match the position of this flat surface.

[Hair dryer]
The hair dryer 1 according to the present invention can be configured by connecting the dryer connection part 36 of the brush attachment 3 described above to the attachment port 102 of a dryer 100 having an attachment port 102 at its tip (see Figs. 1(a) and 1(b)). The hair dryer 1 according to the present invention may be configured so that the dryer connection part 36 is selected and attached so as to fit the attachment port 102 of an existing dryer 100.

In the hair dryer 1 of the present invention, it is preferable to use, for example, a spring for the elastic part 34. The hair dryer 1 equipped with the brush attachment 3 of the present invention uses a spring for the elastic part 34, which gives the hair a uniform firmness and elasticity, thereby reducing the burden on the hair. In other words, the use of a spring eliminates excessive force and allows the hair to receive a uniform tension.

As shown in Figures 6(a) and (b), the brush attachment 3 of this embodiment includes a brush part 20 having a brush band B, and an attachment part 30 having a dryer connection part 36. The dryer connection part 36 is then connected to the mounting port 102 of the dryer 100 to obtain the hair dryer 1 of this embodiment shown in Figures 1(a) and 1(b).

Figure 8 is an exploded perspective view of the brush attachment 3 of this embodiment (see Figure 6 (a)). The brush attachment 3 is broadly composed of a brush part 20 and an attachment part 30.

As shown in Figure 8, the main body of the brush part 20 is composed of a tubular body 10 and a lid part 18 that fits onto its tip. On the surface of the tubular body 10, a plurality of ventilation bands 150 in which ventilation holes 15 are arranged, and tufted bands P, P' are provided. In Figure 8, the brush part 20 is shown in a perspective view from the second surface 12 side, and the ventilation bands 150 are provided on the upper and middle stages of the second surface 12 and the boundary surface 14, respectively. In addition, as tufted bands P, P', tufted bands 12P, 12P' are provided below (on the third surface 13) the ventilation bands 150 provided on the upper and middle stages of the second surface 12, respectively.

The second surface brush bands 12B, 12B' with bristles 22 planted thereon are attached to the bristle planting bands 12P, 12P', respectively. In addition, air direction adjustment pieces 151 are attached to the two ventilation bands 150 provided on the second surface 12, respectively, and a bristle base heat conduction band 230 with a bristle base heat conduction piece 23 arranged thereon is attached to the ventilation band 150 provided on the boundary surface 14, sandwiching a metal band 231 between them.

On the other hand, the attachment part 30 is configured with an elastic part 34 sandwiched between the brush connection part 32 and the dryer connection part 36.

The attachment unit 30 of this embodiment is described in more detail below.

[Brush part 20]
7A is a perspective view of the tubular body 10 of this embodiment as seen from the first surface 11 side. As described above, the tubular body 10 has a front end and a rear end, and its cross section is a substantially isosceles triangle. That is, the tubular body 10 is composed of a first surface 11 and a second surface 12 that form opposing equilateral sides, and a third surface 13 that connects these surfaces, and at least the first surface 11 and the second surface 12 are connected by a boundary surface 14 that is a straight line or a gentle curve in cross section. Here, the first surface 11 and the second surface 12 are curved surfaces that are gentle curves in cross section, and the third surface 13 is a flat surface.

In the tubular body 10, the upper and middle sections of the surface of the first face 11 are provided with vent bands 150 in which vents 15 are arranged from the front end to the rear end of the tubular body 10. A similar vent band 150 is also provided on the boundary surface 14, but in FIG. 7(a), the vent band 150 is covered with a metal band 231 made of a metal piece. At both ends of this metal band 231, holes are provided for attaching the hair base heat conduction band 230, and between the holes at both ends, vents 15 of the same shape are arranged to match each vent 15 of the vent band 150 (see FIG. 8).

(First surface 11 and second surface 12)
As shown in Fig. 7(b), flocked bands 11P and 11P' are provided along each vent band 150 on the lower (third surface 13) side of each vent band 150 provided in the upper and middle sections of the surface of the first surface 11. A wind direction adjusting piece 151 is attached to the upper edge of the vent band 150 provided in the middle section so as to form an angle of 25 to 35 degrees with the vent band 150 (see Fig. 8).

As shown in FIG. 8, brush bands 11B and 11B', each having different types of bristle bundles 22 planted therein, are attached to bristle bands 11P and 11P'. The same is true for the second surface 12, where bristle bands 12P and 12P' are provided on the surface, and brush bands 12B and 12B' are attached thereto.

The brush band 12B and brush band 12B' on the second surface 12 are respectively planted with bristles 22 for combing and bristles 22 for styling (see FIG. 8). Similarly, the brush band 11B and brush band 11B' on the first surface 11 are respectively planted with bristles 22 for combing and bristles 22 for styling.

(Interface 14)
7(a), a metal band 231 is provided above the vent band 150 provided on the boundary surface 14. As shown in FIG. 8, the metal band 231 is composed of a fixing portion 231a located directly above the boundary surface 14 and two airflow direction adjustment pieces 151 extending toward the third surface 13 so as to cover the vent bands 150 provided on the upper levels of the first surface 11 and the second surface 12, respectively.

Referring to FIG. 7(a) or FIG. 8, the elongated hole provided in the fixing portion 231a of the metal band 231 has the same shape as the ventilation hole 15 of the ventilation hole band 150 as described above, and is provided at a position that coincides with the ventilation hole 15 of the ventilation hole band 150 provided at the boundary surface 14 as described above, and is capable of communicating with the inside of the tubular body 10 through the ventilation hole 15. A hair base thermal conduction band 230 with a hair base thermal conduction piece 23 arranged thereon can be attached to the circular holes provided at both ends of the fixing portion 231a.

The two airflow direction adjustment pieces 151 constituting the metal band 231 extend in the direction of the third surface 13 so as to cover the vent bands 150 provided on the upper levels of the first surface 11 and the second surface 12, as described above, and are designed to form an angle of 25 degrees to 35 degrees with the vent bands 150 on the upper levels of the first surface 11 and the second surface 12, respectively. The two airflow direction adjustment pieces 151 constituting this metal band 231 are optimally angled at 30 degrees with the vent bands 150 on the first surface 11 and the second surface 12, but may be movable so that the angle can be adjusted within the range of 25 degrees to 35 degrees. If they are movable, the direction of the hot air sent from the dryer 100 and blown from inside the tubular body 10 can be appropriately adjusted.

(Effect of the brush part)
Hereinafter, a description will be given with reference to Fig. 6(a), Fig. 8, or Fig. 1. First, the hair base heat conductive band 230 provided on the boundary surface 14 receives heat from the metal band 231 heated by hot air sent from the dryer 100 into the inside of the tubular body 10, and conducts the heat to the hair base heat conductive piece 23. The heated hair base heat conductive piece 23 comes into contact with the scalp and the roots of the hair, warming the roots and making the hair soft and easy to style, thus exerting the so-called "root raising" function.

In addition, the airflow direction adjustment pieces 151 provided on the upper stages of the first surface 11 and the second surface 12 supply the warm air sent into the inside of the tubular body 10 to the brush bands 11B and 12B located directly below them on the third surface 13 side. As described above, the brush bands 11B and 12B are sparsely planted with stiff bristle bundles 22, and the brush bands 11B and 12B perform the so-called "combing" function.

In addition, the airflow direction adjustment pieces 151 provided in the middle of the first surface 11 and the second surface 12 supply the warm air sent into the inside of the tubular body 10 to the brush bands 11B' and 12B' located directly below it on the third surface 13 side. The brush bands 11B' and 12B' are densely planted with soft bristle bundles 22, and the brush bands 11B' and 12B' perform the so-called "hair styling" function.

In this embodiment, the brush attachment 3 is used to dry and style the hair by first placing the hair base heat conductive band 230 against the scalp and the roots of the hair, then combing the hair with the upper to middle brush bands B (brush band 11B or brush band 12B) of the first surface 11 or second surface 12 close to the hair base heat conductive band 230, and finally styling the hair with the middle to lower brush bands B' (brush band 11B' or brush band 12B'). In this way, by using the hair base heat conductive piece 23, brush band B (brush band 11B or brush band 12B), and brush band B' (brush band 11B' or brush band 12B') in this order, the functions of "root lifting," "combing," and "hair styling" can be performed all at once by simply passing one surface (first surface 11 or second surface 12) of the brush attachment 3 over the hair. In other words, you can use a single brush to perform a series of steps, such as root lifting, combing, and styling, without having to switch brush parts depending on the purpose, and to recreate volume, firmness, and shine. Also, by limiting the direction of the air from the dryer so that it hits the scalp and hair being brushed in a pinpoint manner, you can effectively perform the series of brushing steps mentioned above (root lifting, combing, and styling) while minimizing damage to the hair caused by heat being trapped in other parts of the scalp and hair.

(Attachment part 30)
As described above, the brush attachment 3 of this embodiment is configured by connecting the dryer connecting portion 36 of the attachment part 30 to the mounting port 102 of the existing dryer 100 to form the hair dryer 1 of this embodiment.

As described above, the attachment part 30 is composed of the brush connection part 32 that is connected to the rear end of the tubular body 10, the dryer connection part 36 that is connected to the mounting port 52 of the dryer 100, and the elastic part 34 that connects these two parts (see Figures 6(a), 6(b), and 8). The dryer connection part 36 may be replaceable so that it fits the mounting port 102 of an existing dryer 100.

In addition, in the attachment part 30 of this embodiment, the elastic part 34 is a spring. By using a spring for the elastic part 34, the hair dryer 1 of this embodiment can apply uniform tension to the hair, reducing the burden on the hair and providing uniform tension to the hair without excessive force.

In addition, in the brush attachment 3 of this embodiment, the third surface 13 is a flat surface that is a straight line in a cross-sectional view, so that it can be placed on a shelf, desk, or table with the third surface 13 facing down, as shown in Figure 6 (b). In response to this, a placement portion 361 that is flush with the third surface 13 is provided on the third surface 13 side of the dryer connection portion 36.

The hair dryer 1 of this embodiment may be made portable by joining the attachment part 30 and the dryer 100 in a foldable manner, as shown in FIG. 9.
