Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, identical parts are designated by the same symbols. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[Embodiment 1]
Hereinafter, an embodiment of the present invention will be described in detail. In this embodiment, the configuration of a hair dryer will be described first, and then the configuration of a hair dryer equipped with a head stimulating device will be described.
(Overall structure of the hair dryer)
Fig. 1 is a perspective view showing the external configuration of a hair dryer 10 according to this embodiment. For convenience in describing the shapes and positional relationships of the components of the hair dryer 10, the hair dryer 10 will be defined by three coordinate axes, namely, the X (X1-X2) direction (left-right direction), the Y (Y1-Y2) direction (up-down direction), and the Z (Z1-Z2) direction (front-rear direction) as shown in Fig. 1.

Figure 2 shows the appearance of the hair dryer 10 shown in Figure 1 when viewed from the side (X2 side). Figure 3 shows a cross section of the hair dryer 10 shown in Figure 1 when viewed from the side (X2 side).

As shown in FIG. 1, the hair dryer 10 is primarily composed of a main body 11 and a handle 20. The main body 11 has an air outlet 12 on the front side (Z1 side) of the front portion 11a for blowing out air, and an air inlet 23 on the rear side (Z2 side) for drawing in air. Furthermore, the main body 11 has an internal air blowing mechanism (such as the air blower 150 (FIG. 3)) and an air outlet path (air blowing path). This allows the main body 11 to blow air drawn in through the air inlet 23 out of the air outlet 12 (specifically, the first air outlet 12a and the second air outlet 12b). In addition to blowing hot and cold air, the hair dryer 10 may also generate charged particles (ions) and blow them onto the head.

As shown in Figure 3, the blower unit 150 has at least a centrifugal fan 151, a motor 153, and a motor fixing part 152. By driving the motor 153 and rotating the centrifugal fan 151, air is drawn in through the intake port 23 of the main body 11, heated or cooled inside, and then blown out from the outlet 12.

The air outlet 12 is composed of two air outlets, a first air outlet 12a and a second air outlet 12b, formed at the left and right (X1-X2) ends of the front portion 11a. That is, the first air outlet 12a and the second air outlet 12b are formed on the left and right (X1-X2) outer edge sides of the front portion 11a of the main body 11.

The first air outlet 12a is formed in the vertical direction (Y direction) along the left (X1 side) edge of the front portion 11a when viewed from the front. The second air outlet 12b is formed in the vertical direction (Y direction) along the right (X2 side) edge of the front portion 11a when viewed from the front.

The first and second air outlets 12a, 12b have openings that are elongated (vertically long) in the vertical direction (Y direction). More specifically, the first and second air outlets 12a, 12b are formed in an arc shape along part of the outer periphery of the generally circular front portion 11a. Because the openings of the first and second air outlets 12a, 12b have such shapes, when drying hair using the hair dryer 10, the longitudinal direction of each opening can be aligned with the growth direction of the hair at the treatment area.
The front surface 11a is provided with a display unit 30 and an irradiation unit 50 (first irradiation unit 50a, second irradiation unit 50b) formed inside the first air outlet 12a and the second air outlet 12b. Details of the display unit 30, the first irradiation unit 50a, and the second irradiation unit 50b will be described later.

The grip portion 20 is located below the main body 11. The grip portion 20 is the part that the user holds when using the hair dryer 10. As shown in Figure 2, when the hair dryer 10 is viewed from the side (e.g., the X2 side), the grip portion 20 extends downward (towards the Y2 side) from approximately the center of the main body 11 in the front-to-rear direction (Z direction).

The Z1 side of the grip part 20 forms the front part 20a. The front part 20a of the grip part 20 is provided with the operation part 40. When using the hair dryer 10, the user operates the operation part 40 (specifically, the power switch 42) to start or stop the operation of the hair dryer 10. In addition, by operating the operation part 40 (specifically, the operation button 41), the type of air (hot air/cold air) and air volume blown out from the air outlet 12 can be adjusted. In addition, by operating the operation part 40 (specifically, the operation button 41), the operating mode of the hair dryer 10 can be switched.

A power cord 22 is attached to the lower part of the grip portion 20. In another aspect of the present invention, the hair dryer 10 may be a cordless type. In this case, for example, a primary or secondary battery is provided inside the main body 11 or the grip portion 20.

(About the external shape of the hair dryer)
Next, the external shape of the hair dryer 10 will be described.

As shown in Figure 2, the hair dryer 10 has a generally T-shape when viewed from the side. Also, as shown in Figure 1, the front side (Z1 side) of the hair dryer 10 is composed of a generally circular front portion 11a, a generally rectangular front portion 20a that is narrower than the front portion 11a, and an inclined surface 20b whose width gradually narrows from the front portion 11a toward the front portion 20a.

The display unit 30, first irradiation unit 50a, second irradiation unit 50b, and operation unit 40 are all located on the front side (Z1 side) of the hair dryer 10. Furthermore, at least one of the multiple operation buttons 41 that make up the operation unit 40 is located on the inclined surface 20b.

As shown in Figure 1, the approximately circular front portion 11a has a left end portion 13a located on the leftmost side when viewed from the Z1 side, a right end portion 13b located on the rightmost side, an upper end portion 14a located on the uppermost side, and a lower end portion 14b located on the lowermost side.

As shown in FIG. 1 and other figures, the front portion 11a has a curved, concave shape. Furthermore, in this curved, concave front portion 11a, the left-right (X-direction) ends (i.e., the left end 13a and the right end 13b) are located closer to the front (Z1 side) than the up-down (Y-direction) ends (i.e., the upper end 14a and the lower end 14b) in side and top (or bottom) views. In other words, the up-down (Y-direction) ends of the main body 11 are recessed further upstream (Z2 side) in the airflow than the left-right (X-direction) ends of the main body 11. Furthermore, in the concave front portion 11a, the lower end 14b is recessed further upstream (Z2 side) in the airflow than the upper end 14a in bottom view.

The display unit 30 is located near the center of the front surface 11a, recessed from the left-right (X-direction) ends 13a and 13b where the first and second air outlets 12a and 12b are located. The display unit 30 is also located on the lower end 14b side of the front surface 11a, which does not protrude forward (toward the Z1 side) from the upper end 14a.

This allows the user to view the contents of the display unit 30 when looking at the front portion 11a of the hair dryer 10 from diagonally forward, as shown in Figure 1. If the front portion 11a is flat, it may be difficult to view the information on the display unit 30, which is located between the first and second air outlets 12a and 12b, due to factors such as light reflection. In contrast, in this embodiment, the display unit 30 is located in a recessed portion of the front portion 11a, which has a curved, concave shape. This reduces the effects of light reflection, making it easier to view the display unit 30. This configuration also makes it possible to view the display unit 30 from a wider range of directions (e.g., from a steeply inclined oblique direction).

(Configuration of the front part of the hair dryer)
Next, the configuration of the front portion of the hair dryer 10 will be described with reference to Figure 4. The front portion of the hair dryer 10 is mainly composed of a front portion 11a of the main body 11, a front portion 20a of the grip portion 20, and an inclined surface 20b.

A first air outlet 12a is provided on the left side of the front portion 11a when viewed from the Z1 side, running along the outer periphery of the front portion 11a. A second air outlet 12b is provided on the right side of the front portion 11a when viewed from the Z1 side, running along the outer periphery of the front portion 11a. The first air outlet 12a extends vertically around the left end 13a. The second air outlet 12b extends vertically around the right end 13b.

The front portion 11a has a concave shape between the first air outlet 12a and the second air outlet 12b. That is, the center portion of the front portion 11a (where the distance sensor 60 is formed) is recessed furthest to the rear (upstream in the airflow direction). In this embodiment, the center portion has a substantially flat shape.

A first irradiation unit 50a is provided between the first air outlet 12a and the central portion, and a second irradiation unit 50b is provided between the second air outlet 12b and the central portion. In other words, the first irradiation unit 50a and the second irradiation unit 50b are formed further inward than the positions of the first air outlet 12a and the second air outlet 12b, respectively, on the front surface 11a of the main body 11.

Furthermore, on the front portion 11a of the main body portion 11, a display portion 30 that displays the operating status of the hair dryer 10 is provided inside the first irradiation portion 50a and the second irradiation portion 50b.

Below the center of the front portion 11a and on the outer periphery of the center portion are operation mode display portions 31 (31a-31f) that display the operation mode, which constitute part of the display portion 30, and above the center portion is a temperature display portion 32. As such, the display portion 30 is positioned in a recessed position upstream of the air outlet 12, which is located at the downstream end of the air outlet path. In other words, the display portion 30 is positioned in a recessed position in the front portion 11a.

Furthermore, a distance sensor 60 is formed in the center of the front portion 11a. This distance sensor 60 measures the distance from the hair dryer 10 to the user (head) of the hair dryer 10. The measurement value by the distance sensor 60 is used to control various operations of the hair dryer 10.

An operating unit 40 is provided on the inclined surface 20b located below the front surface 11a and on the front surface 20a of the grip portion 20. The operating unit 40 has multiple operating buttons 41 and a power switch 42.

(Regarding the display)
Next, we will explain the specific configuration of the display unit 30. The display unit 30 is located at the downstream end of the airflow path (i.e., the front surface 11 a). The display unit 30 is composed of an operation mode display unit 31 and a temperature display unit 32.

The operation mode display unit 31 is a display unit for displaying the various operation modes of the hair dryer 10, such as normal mode, quick dry mode, styling mode, and hair care mode (ion blow mode). In this embodiment, the operation mode display unit 31 is composed of six LED lamps 31a to 31f.

As shown in Figure 4, the multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f that make up the operation mode display unit 31 are arranged in a vertical row (Y direction) below the front part 11a. The user of the hair dryer 10 switches the operation mode of the hair dryer 10 by operating the operation button 41 of the operation unit 40. Then, the LED lamp among the multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f that corresponds to the selected current operation mode lights up.

In one example, when the operating mode of the hair dryer 10 is normal mode, only the topmost LED lamp 31a lights up. When the operating mode of the hair dryer 10 is quick dry mode, only the second-highest LED lamp 31b lights up. When the operating mode of the hair dryer 10 is styling mode, only the third-highest LED lamp 31c lights up. When the operating mode of the hair dryer 10 is hair care mode, only the bottommost LED lamp 31d lights up. When the operating mode of the hair dryer 10 is scalp care mode (1), only LED lamp 31e lights up. When the operating mode of the hair dryer 10 is scalp care mode (2), only LED lamp 31f lights up.

The multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f that make up the operation mode display unit 31 are aligned vertically in the approximate center of the left-right direction (X direction) of the front portion 11a, located between the first and second air outlets 12a and 12b. Each LED lamp 31a, 31b, 31c, 31d, 31e, and 31f is also located on an extension of a center line that passes through the approximate center of the front portion 20a. This makes it easier for users to check which of the multiple LED lamps 31a, 31b, 31c, 31d, 31e, and 31f is lit. Therefore, users can easily check the current operation mode while using the hair dryer 10.

The temperature display unit 32 indicates the temperature of the air blown out from the air outlet 12, such as hot air or cold air. The temperature display unit 32 displays the air temperature, for example, by color. Specifically, when hot air is blown out, the temperature display unit 32 turns red, and when cold air is blown out, the temperature display unit 32 turns blue.

In this case, the temperature display unit 32 is composed of a red LED lamp, a blue LED lamp, etc. When warm air is blown out from the air outlet 12, the red LED lamp lights up and emits a color. When cool air is blown out from the air outlet 12, the blue LED lamp lights up and emits a color. This allows the user to easily distinguish whether the air being blown out is warm air or cool air.

(Irradiation unit)
As shown in Fig. 4, the first irradiation unit 50a and the second irradiation unit 50b each include two red LEDs 51a (red light irradiation units) that irradiate red light and two blue LEDs 51b (blue light irradiation units) that irradiate blue light. In the first irradiation unit 50a and the second irradiation unit 50b, the red LEDs 51a and the blue LEDs 51b are arranged around the periphery of the display unit 30. In this embodiment, as shown in Fig. 4, the red LEDs 51a and the blue LEDs 51b are arranged to sandwich the display unit 30 from the left and right (X1-X2) directions, but the arrangement is not limited to this.

The red LEDs 51a and blue LEDs 51b of the first irradiation unit 50a are arranged along the first air outlet 12a. Here, from the Y1 side to the Y2 side, the red LEDs 51a, blue LEDs 51b, blue LEDs 51b, red LEDs 51a are arranged in a row at approximately equal intervals. That is, the two blue LEDs 51b are arranged adjacent to each other, and the two red LEDs 51a are arranged with two adjacent blue LEDs 51b in between. Note that the red LEDs 51a and blue LEDs 51b may be arranged so that the centers of the LEDs are located on a straight line, or so that the centers of the LEDs are located on an arc-shaped imaginary line that follows the arc-shaped first air outlet 12a.

Similarly, the red LEDs 51a and blue LEDs 51b of the second irradiation unit 50b are arranged along the second air outlet 12b. Here, as an example, they are arranged at approximately equal intervals from the Y1 side to the Y2 side in the order of red LED 51a, blue LED 51b, blue LED 51b, red LED 51a. That is, two blue LEDs 51b are arranged adjacent to each other, and two red LEDs 51a are arranged with two adjacent blue LEDs 51b in between. Note that these red LEDs 51a and blue LEDs 51b may be arranged so that the centers of each LED are located on a straight line, or so that the centers of each LED are located on an arc-shaped imaginary line that follows the arc-shaped second air outlet 12b.

The first irradiation unit 50a and the second irradiation unit 50b are configured to irradiate LED light in the same direction as the air blowing out from the first air outlet 12a and the second air outlet 12b. This allows the LED light irradiated from the first irradiation unit 50a and the second irradiation unit 50b to be irradiated onto the scalp together with the air blowing out from the first air outlet 12a and the second air outlet 12b.

The red LED light emitted from the red LED 51a has a wavelength range of 618 nm to 635 nm, and the blue LED light emitted from the blue LED 51b has a wavelength range of 405 nm to 415 nm. Irradiating the scalp with either type of LED light is expected to improve the scalp environment.
In addition to irradiating the scalp with LED light, direct stimulation of the head can also improve the scalp environment. Below, we will explain an example in which a head stimulator that directly stimulates the head is attached to the hair dryer 10 shown in Figure 1.

(Overview of head stimulators)
Fig. 5 is a perspective view of the external configuration of the head stimulation unit 70 as seen from the front side (Z1 side). Fig. 6 is a side view of the head stimulation unit 70 as seen from the side side (X2 side).

The head stimulator 70 includes a first rod-shaped body portion (stimulator) 71, a second rod-shaped body portion (stimulator) 72, a main body portion 73 to which the first rod-shaped body portion 71 and the second rod-shaped body portion 72 are attached, and an attachment portion 74 used when attaching the main body portion 73 to the hair dryer 10, and is detachably attached to the hair dryer 10. The first rod-shaped body portion (stimulator) 71 and the second rod-shaped body portion (stimulator) 72 can hold the head from both sides.
The main body 73 has a generally cylindrical shape with an inner diameter slightly larger than the outer diameter of the air outlet 12 of the hair dryer 10, and has the first rod-shaped body 71 and the second rod-shaped body 72 attached to its front end 73a (Z1 side), and a rear end 73b (Z2 side) that fits onto the outer periphery of the air outlet 12 of the hair dryer 10. The main body 73 also has engaging members 75 that engage with the upper and lower ends of each air outlet (first air outlet 12a, second air outlet 12b). The engagement of the main body 73 with the air outlet 12 by the engaging members 75 will be described in detail below.

The first rod-shaped body portion 71 is provided on the left side (X1 side) when viewing the main body portion 73 from the front side (Z1 side), and the second rod-shaped body portion 72 is provided on the right side (X2 side) when viewing the main body portion 73 from the front side (Z1 side). The first rod-shaped body portion 71 and the second rod-shaped body portion 72 are made of flexible material.

The first rod-shaped body portion 71 has multiple rod-shaped bodies 71a resembling fingers that extend in the same direction (from Z2 to Z1) as the air blowing out from the air outlet 12 of the hair dryer 10. The multiple rod-shaped bodies 71a are flexible and are designed so that their tips can bend smoothly inward (towards X2).

Like the first rod-shaped body 71, the second rod-shaped body 72 also has multiple rod-shaped bodies 72a resembling fingers that extend in the same direction (from Z2 to Z1) as the air blowing out from the air outlet 12 of the hair dryer 10. The multiple rod-shaped bodies 72a are flexible and are designed so that their tips can bend smoothly inward (towards X1).

As described above, the first rod-shaped body 71 and the second rod-shaped body 72 are made of flexible materials. Therefore, when the head is inserted between the first rod-shaped body 71 and the second rod-shaped body 72, the first rod-shaped body 71 bends to the left (X1 side), and the second rod-shaped body 72 bends to the right (X2 side). This allows the head stimulation device 70 to be repeatedly moved toward and away from the head (reciprocating movement), thereby stimulating the head with the first rod-shaped body 71 and the second rod-shaped body 72. In other words, the rod-shaped body 71a of the first rod-shaped body 71 and the rod-shaped body 72a of the second rod-shaped body 72 of the head stimulation device 70 part the hair on the head, their respective tips contacting the scalp and stimulating the scalp. Furthermore, the head stimulation device 70 can be moved reciprocatingly relative to the head to part the hair. In other words, the head stimulating member 70 makes it possible to comb the hair while stimulating the user's head.

Next, we will explain the hair dryer 10 equipped with the head stimulator 70.

(Hair dryer with head stimulator attached)
Fig. 7 is a perspective view showing the external appearance of the hair dryer 10 equipped with the head stimulator 70 when viewed from the front side (Z1 side). Fig. 8 is a side view of the hair dryer 10 equipped with the head stimulator 70 when viewed from the side side (X2 side). Fig. 9 is a front view of the hair dryer 10 equipped with the head stimulator 70 when viewed from the front side (Z1 side).

As shown in Figure 9, the attachment positions of the first rod-shaped body portion 71 and the second rod-shaped body portion 72 that make up the head stimulation unit 70 are symmetrical with respect to an imaginary line X that extends from the grip portion 20 to the main body portion 11 of the hair dryer 10 when viewed from the front of the main body portion 11. However, this is not limited to this.

When attaching the head stimulator 70 to the hair dryer 10, the attachment portion 74 and engagement member 75 are used to prevent it from detaching from the front end 73a of the main body 73. The attachment portion 74 has a first attachment portion 74a that attaches to the upper end of the front end 73a of the main body 73, and a second attachment portion 74b that attaches to the lower end of the front end 73b of the main body 73. The engagement member 75, supported by the first attachment portion 74a and the second attachment portion 74b, engages with the air outlet 12 of the hair dryer 10, thereby attaching the head stimulator 70 to the hair dryer 10. The engagement member 75 is an elastic plate-shaped member that extends in the vertical direction (Y direction). The engagement member 75 has engagement portions 75a formed at its four corners, and each engagement portion 75a is shaped to engage with the upper and lower ends of the first air outlet 12a and the second air outlet 12b that constitute the air outlet 12 of the hair dryer 10. The engaging member 75 is shaped so as not to block the left and right sides (X1-X2) of the main body 73 when the head stimulation device 70 is attached to the hair dryer 10. That is, the engaging member 75 is shaped so as not to block the first air outlet 12a and the second air outlet 12b formed at the left and right ends (X1-X2) of the front part 11a of the main body 11 of the hair dryer 10 when the head stimulation device 70 is attached to the hair dryer 10. Furthermore, the attachment part 74 is shaped so as not to block the irradiation part 50 (first irradiation part 50a, second irradiation part 50b) formed inside the first air outlet 12a and second air outlet 12b formed on the front part 11a.

9, when the head stimulation unit 70 is attached to the hair dryer 10, the first rod-shaped body 71 and the second rod-shaped body 72 constituting the head stimulation unit 70 are attached to the main body 73 so as not to block the first air outlet 12a and the second air outlet 12b when viewed from the front side (Z1 side). In other words, the attachment positions of the first rod-shaped body 71 and the second rod-shaped body 72 are such that the first rod-shaped body 71 and the second rod-shaped body 72 do not overlap the first air outlet 12a and the second air outlet 12b when viewed from the front of the main body 11.
The first rod-shaped body portion 71 and the second rod-shaped body portion 72 need only be attached so as not to block at least the wind (main stream wind) blowing from the first air outlet 12a and the second air outlet 12b from the front of the main body portion 11 toward the object (head) facing the front.
Furthermore, the attachment positions of the first rod-shaped body portion 71 and the second rod-shaped body portion 72 are such that, when viewed from the front of the main body portion 11, the first rod-shaped body portion 71 and the second rod-shaped body portion 72 do not overlap with the irradiation portion 50 (first irradiation portion 50a, second irradiation portion 50b).
The mounting positions of the first rod-shaped body portion 71 and the second rod-shaped body portion 72 need only be such that they do not block the optical axis of the LED light irradiated from the irradiation portion 50 (first irradiation portion 50a, second irradiation portion 50b) by at least the first rod-shaped body portion 71 and the second rod-shaped body portion 72.
(effect)
FIG. 10 is a diagram showing an example of a user 101 using the hair dryer 10 equipped with the head stimulating device 70. As shown in FIG.

The user 101 applies the first rod-shaped body portion 71 and the second rod-shaped body portion 72 of the head stimulator 70 to their head while massaging their scalp with the rod-shaped body 71a of the first rod-shaped body portion 71 and the rod-shaped body 72a of the second rod-shaped body portion 72. The first rod-shaped body portion 71 and the second rod-shaped body portion 72 are attached in positions that do not block the optical axis of the LED light emitted from the irradiation unit 50 of the hair dryer 10, and do not block the mainstream air blown out from the air outlet 12 of the hair dryer 10. This allows the head stimulator 70 to stimulate the user's 101's head while combing their hair, effectively applying the mainstream air and LED light from the hair dryer 10 to the scalp while massaging the scalp. This provides the effect of effectively providing scalp care for the user 101 by using the hair dryer 10 equipped with the head stimulator 70. 10, the hair dryer 10 equipped with the head stimulating member 70 is used to hold the head from above, but this is not limited to this. For example, the hair dryer 10 equipped with the head stimulating member 70 may be used to hold the sides of the head from the front and back, or may be used to hold the head from any direction.

In order to provide more effective scalp care for the user 101, it is conceivable to use a separate head stimulation attachment 80 in addition to the hair dryer 10 equipped with the head stimulation body 70.
[Embodiment 2]
Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

In this embodiment, we will describe an example in which a hair dryer 10 equipped with the head stimulation body 70 in embodiment 1 is further equipped with another head stimulation attachment.

(Attachment Overview)
Fig. 11 shows the external configuration of the attachment 80, as viewed from the front (Z1 side). Fig. 12 shows the external configuration of the head stimulation unit 70 with the attachment 80 attached, as viewed from the front (Z1 side). Fig. 13 is a side view of the head stimulation unit 70 with the attachment 80 attached, as viewed from the side (X2 side).

The attachment 80 includes a base portion 81, a first mounting portion 82 and a second mounting portion 83 for mounting the base portion 81 to the head stimulation unit 70, and a plurality of first protrusions 84 and second protrusions 85 protruding from the surface 81a of the base portion 81. Here, the surface 81a of the base portion 81 refers to the surface opposite the back surface that faces the head stimulation unit 70 when attached to the head stimulation unit 70.

The base portion 81 is made of a substantially circular plate-shaped member, and predetermined areas on both ends (X1-X2 sides) are translucent. The outer diameter of the base portion 81 is set to a size that does not block the air outlets 12 (first air outlet 12a, second air outlet 12b) of the hair dryer 10 when the base portion 81 is attached to the head stimulation device 70.

The first attachment portion 82 is provided on the upper end side (Y1 side) of the base portion 81, and has an engagement portion 82a that engages with the upper end portion 74a of the attachment portion 74 of the head stimulation body 70 when the attachment 80 is attached to the head stimulation body 70.

The second attachment portion 83 is provided on the lower end side (Y2 side) of the base portion 81, and has an engagement portion 83a that engages with the lower end portion 74b of the attachment portion 74 of the head stimulation body 70 when the attachment 80 is attached to the head stimulation body 70.

Four first protrusions 84 are provided along the translucent region on each end of both sides (X1-X2 sides) of the surface 81a of the base portion 81. Each first protrusion 84 has a translucent central portion 84a extending from the base portion 81 side to its tip, and a non-translucent peripheral portion 84b provided on the outer periphery of the central portion 84a. Specifically, the peripheral portion 84b is cone-shaped and contains a non-translucent material, and the central portion 84a is formed by a through-hole that extends from the base portion 81 side of the first protrusion 84 to its tip, narrowing the outer periphery 84b. In other words, the outer periphery 84b corresponds to a cone-shaped body located on the outer periphery of the central portion 84a, which is a through-hole. The through-hole, which is the central portion 84a, is provided at the center of the cone-shaped body along the protruding direction of the peripheral portion 84b.

As a result of the translucent central portion 84a being surrounded on its outer periphery by the outer peripheral portion 84b containing a non-translucent material, light entering from the base portion 81 side of the central portion 84a does not enter the outer peripheral portion 84b. This reduces the attenuation of light entering from the base portion 81 side of the central portion 84a. This allows light entering from the base portion 81 side of the central portion 84a to be efficiently guided to the tip of the first protrusion 84 (central portion 84a), and light can be emitted from the tip along the protrusion direction of the first protrusion 84.

The second protrusions 85 consist of small protrusions 85a provided adjacent to the first protrusions 84 at both ends (X1-X2 sides) of the surface 81a of the base 81, and a large protrusion 85b provided in the center of the surface 81a of the base 81. Both the small protrusions 85a and the large protrusions 85b are cone-shaped bodies containing a non-translucent material. Note that the small protrusions 85a and the large protrusions 85b may be translucent.

The first protrusion 84 and the second protrusion 85 both have a convexly curved surface at the tip. The first protrusion 84 and the second protrusion 85 only need to be long enough to stimulate the center of the head when the attachment 80 is attached to the head stimulation device 70 and the first rod-shaped body 71 and the second rod-shaped body 72 are stimulating both sides of the head. In this way, the head stimulation device 70 with the attachment 80 attached can provide more stimulation to the user's head.

Next, we will explain the hair dryer 10 equipped with a head stimulator 70 to which an attachment 80 is attached.

(Hair dryer with head stimulator attached)
Fig. 14 is a perspective view showing the external appearance of the hair dryer 10 equipped with the head stimulator 70 to which the attachment 80 is attached, as viewed from the front side (Z1 side). Fig. 15 is a side view of the hair dryer 10 equipped with the head stimulator 70 to which the attachment 80 is attached, as viewed from the side side (X2 side). Fig. 16 is a front view of the hair dryer 10 equipped with the head stimulator 70 to which the attachment 80 is attached, as viewed from the front side (Z1 side).

To attach the attachment 80 to the head stimulation unit 70, first, while facing the back of the base part 81 of the attachment 80 toward the main body part 73 of the head stimulation unit 70, engage the first attachment part 82 and the second attachment part 83 with the engagement parts provided on the main body part 73. This allows the attachment 80 to be attached to the head stimulation unit 70 without coming off.

Here, the base 81 of the attachment 80 is shaped so as not to block the left and right sides (X1-X2) of the main body 73 when the head stimulation unit 70 with the attachment 80 attached is attached to the hair dryer 10. In other words, the base 81 is shaped so as not to block the first air outlet 12a and the second air outlet 12b formed at the left and right ends (X1-X2) of the front part 11a of the main body 11 of the hair dryer 10 when the head stimulation unit 70 with the attachment 80 attached is attached to the hair dryer 10.

The base portion 81 of the attachment 80 is shaped to block the irradiation portion 50 (first irradiation portion 50a, second irradiation portion 50b) formed inside the first air outlet 12a and second air outlet 12b formed on the front portion 11a. However, the first protrusion portion 84 formed on the base portion 81 is formed on the base portion 81 facing the first irradiation portion 50a and second irradiation portion 50b when the head stimulation device 70 is attached to the hair dryer 10. This allows light emitted from the first irradiation portion 50a and second irradiation portion 50b to be emitted from the tip of the first protrusion portion 84.

The first protrusion 84 is provided to correspond to the red LED 51a and blue LED 51b included in the first irradiation unit 50a and second irradiation unit 50b, respectively. Therefore, red LED light or blue LED light is emitted from the tip of the first protrusion 84. This makes it possible to irradiate the scalp with red LED light or blue LED light from a close distance, allowing for more effective scalp care using LED light.

(effect)
With the hair dryer 10 equipped with the head stimulator 70 to which the attachment 80 is attached, the first rod-shaped body portion 71 and the second rod-shaped body portion 72 of the head stimulator 70 grip the user's head to stimulate it, while the first protrusion portion 84 and the second protrusion portion 85 of the attachment 80 further stimulate the scalp. Moreover, since the first protrusion portion 84 can irradiate the scalp with red and blue LED lights at close range, scalp care using the LED light can be performed more effectively.

In the above embodiments, the number of red LEDs 51a and blue LEDs 51b included in the first irradiation unit 50a and the second irradiation unit 50b is two each, but this is not limited to this. Furthermore, the arrangement of the red LEDs 51a and blue LEDs 51b is not limited to the order of red LED 51a, blue LED 51b, blue LED 51b, red LED 51a.

For example, the first irradiation unit 50a may include one red LED 51a and one blue LED 51b, and the second irradiation unit 50b may also include one red LED 51a and one blue LED 51b. Alternatively, the first irradiation unit 50a and the second irradiation unit 50b may only include LEDs of the same color. For example, the first irradiation unit 50a may include two or more red LEDs 51a (or blue LEDs 51b), and the second irradiation unit 50b may also include two or more red LEDs 51a (or blue LEDs 51b).
