This application is based upon and claims the benefit of priority from Japan Patent Application No. 2015-143490, filed on Jul. 17, 2015, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELDThe embodiment of the present disclosure relates to a photoirradiation hair dyeing device used to dye hair by using light.
RELATED ARTConventionally, as a hair dyeing method, a photoirradiation hair dyeing technology, which is a hair dyeing by using light, has been developed. This photoirradiation hair dyeing technology dyes hair, first by applying a photoirradiation hair dyeing agent including specific substance which colors when reacting with light (for example, a silver salt) is applied to hair, and then by exposing the hair to sunlight or fluorescent lamps (see, for example, JP 2008-069131A) to color the photoirradiation hair dyeing agent. This photoirradiation hair dyeing technology can easily be used in home to dye hair simply, since there is no need to take time or wash the dye away after applying the dye.
However, when exposed to sunlight or fluorescent lamps, a condition of light irradiation does not stabilize as it is difficult for one who is to photoirradiation hair dye to control an intensity of light and a direction of light irradiation thereto.
Therefore, a brush form photoirradiation hair dyeing device having a light emission mechanism is suggested as a technology to provide the photoirradiation hair dyeing device capable of photoirradiation hair dyeing, regardless of a condition of illumination such as sunlight or the fluorescent lamps (see, for example, JP 2012-055370A).
With a device of JP 2012-055370A, a user must keep a brush fixed until the hair dyeing on brushed parts are completed. The user's hand will be occupied for a long time while performing the photoirradiation hair dyeing, losing the original easiness of the photoirradiation hair dyeing rather increasing the user's load.
SUMMARYThe present disclosure is suggested to solve the problems above, and the present disclosure provides the photoirradiation hair dyeing device that has little load to the user.
The photoirradiation hair dyeing device of the present disclosure dyes hair by light irradiation after applying the photoirradiation hair dye agent to the hair. The photoirradiation hair dyeing device includes: a hood, having an opening portion through which a user's head is inserted and an internal surface; a supporting portion, holding the hood in midair; and a light emitting component, arranged in the internal surface of the hood.
The supporting portion may have: a base to be placed on a floor; and a pillar standing on the base.
The hood is a substantially truncated pyramid shape, a substantially truncated cone shape, or a substantially hemispherical shape and the light emitting components are arranged on an entire of the internal surface at equal intervals.
A light diffuse reflecting component which diffuses light of the light emitting components may be arranged on the internal surface of the hood at equal intervals.
The light diffuse reflecting components may be arranged around the opening portion of the hood, and the light emitting components may be arranged around an apex portion of the hood.
The photoirradiation hair dyeing device may have: an angle adjusting mechanism, adjusting an angle of the opening portion of the hood against the floor.
The photoirradiation hair dyeing device may have: a height adjusting mechanism, adjusting a height of the supporting portion.
The photoirradiation hair dyeing device may have: a dimmer, adjusting an intensity of light, an irradiation angle, or an irradiation range of the light emitting components.
The user does not need to hold the photoirradiation hair dyeing device during the irradiation, because the photoirradiation hair dyeing device is held in midair by the supporting portion. Therefore, the user can use the photoirradiation hair dyeing device without any specific operation. Therefore, the user's load when using the photoirradiation hair dyeing device will be reduced, and the photoirradiation hair dyeing can be done easily.
Some embodiments of the photoirradiation hair dyeing device are specifically explained below with reference to
(Constitution)
As shown in
The supporting portion 2 is a portion for holding the hood 1 in midair. In the present embodiment, the supporting portion 2 includes a pillar 21 and a base 22 for supporting the pillar 21. The pillar 21 supports the hood 1 on an upper side.
The base 22 is placed on the floor and is a portion for supporting the pillar 21. The base 22 has optional shapes such as, though not limited to, cylinder or cuboid which can be placed on the floor, and holds the pillar 21 at stand position on the upper side thereof.
The pillar 21 is a member which supports the hood 1 on the upper side, and the pillar 21 stands up from the base 22 towards a top. For example, the pillar 21 includes two pipes, i.e., a lower pipe 21a and an upper pipe 21b. The lower pipe 21a is placed on an upper surface of the base 22 and connected to the base 22 by welding, such that a longitudinal direction of the lower pipe 21a is along with a vertical direction.
A tightening nut 3 is a height adjusting mechanism as well as a fixture of the upper pipe 21b and the lower pipe 21a. The height adjusting mechanism is a mechanism to make the supporting portion 2 extensible in a height direction that is the vertical direction.
As shown in
The hood 1 is held by the supporting portion 2, such that the opening portion 1a faces against the floor. Furthermore, one point of the periphery portion or the apex portion 1c of the hood 1 is attached to the upper side of the pillar 21 via the angle adjusting mechanism 4.
The angle adjusting mechanism 4 is a joint component which enables an angle of the hood 1 to change at optional angle. The angle of the hood 1 is an angle between the opening portion 1a and the floor, when regarding the opening portion 1a of the hood 1 as a surface. A known angle adjusting metal fitting and the like can be applied as the angle adjusting mechanism 4.
The light emitting components 5 are components arranged to the internal surface 1b to irradiate light to hair. The light emitting components 5 include components emitting light having a wavelength that enables photoirradiation hair dye. For example, the fluorescent lumps or LED and the like can be used.
The light emitting components 5 are arranged to the internal surface 1b of the hood 1 at equal intervals. The light emitting component 5 is horizontally stripe pattern parallel to the opening portion 1a of the hood 1, in other words, placed concentrically to the apex of the hood 1 as a center.
Although not illustrated, a body of the photoirradiation hair dyeing device 10 has a switch to turn on or off the photoirradiation hair dyeing device 10. A power is on when turning on the switch and the light irradiation from the light emitting components 5 starts. A power is off when turning off the switch and the light irradiation from the light emitting components 5 stops.
The body of the photoirradiation hair dyeing device 10 includes the dimmer 7 that can adjust the intensity of light, the irradiation angle, or the irradiation range of the light emitting components 5. The dimmer 7 includes: a first dial 7a for adjusting the intensity of light, and the second dial 7b for adjusting the irradiation angle and the irradiation range of light according to a length of hair.
The first dial 7a adjusts the intensity of light. By increasing a number of the first dial 7a of the dimmer 7, the intensity of light irradiated from the light emitting components 5 increases, and an amount of light irradiated increases. By decreasing the number of the first dial 7a of the dimmer 7, the intensity of light irradiated from the light emitting components 5 decreases, and an amount of light irradiated decreases.
The second dial 7b adjusts the irradiation angle and range according to the length of hair. Here, there are two types of settings, “SHORT” for short hair and “LONG” for long hair. When the second dial 7b is set to “LONG”, all the light emitting components 5 irradiates light. Furthermore, the irradiation angle of the light emitting components 5 around the opening portion 1a is directed towards the floor. When the second dial 7b is set to “SHORT”, the light emitting components 5 around the opening portion 1a do not irradiate light.
Although not illustrated, the hood 1 includes a heat vent. The heat vent is provided by arranging holes on optional position of the hood 1. The number and size of the holes is not limited. By arranging the heat vent, a heat of the light emitting components 5 can be exhausted to the outside of the hood 1.
(Function)
A function of the photoirradiation hair dyeing device 10 of the present embodiment, with a behavior of the user, is explained below.
In advance, the user applies known photoirradiation hair dyeing agent to hair. The agent may be applied to the desired portion of hair, and it may be the entire hair or only a part of a hair root.
The user adjusts the height and the angle of the hood 1, so that the user's head is placed in a center of the space S surrounded by the internal surface 1b of the hood 1. For example, when the user uses the photoirradiation hair dyeing device 10 while sitting on a chair, the user first checks the height position of the user's head. Then, the height of the supporting portion 2 is adjusted so that the height of the hood 1 will be as same as the height checked by the height adjusting mechanism. When the tightening nut 3 is loosened, the height of the supporting portion 2 can be adjusted by moving the upper pipe 21b in the vertical direction. Also, when the tightening nut 3 is tightened, the upper pipe 21b will be fixed, and the height of the supporting portion 2 will be fixed. Therefore, the hood 1 arranged on the upper side of the supporting portion 2 can be adjusted and fixed. In addition, the user can move the angle of the hood 1, so that the edge of the opening portion 1a of the hood 1 will not hit the head while sitting.
The user switches the photoirradiation hair dyeing device 10 on. The photoirradiation hair dyeing device 10 starts, and light will be irradiated from the light emitting components 5. The hair will be exposed to the light irradiated, and photoirradiation hair dyeing will proceed. As a result, a color of the hair gradually changes by the time, and the hair will be dyed.
After the photoirradiation hair dyeing device 10 is switched on, the user adjusts the amount of light using the first dial 7a of the dimmer 7. A speed of the photoirradiation hair dyeing differs in accordance with the amount of light irradiated. Therefore, the user adjusts the amount of light depending on a color or timing of dyeing desired. For example, if the white hair should be dyed slowly, the dyeing is performed with less amount of light. Conversely, if hair dye should be performed quickly, the dyeing is performed with more amount of light.
If the dyeing proceeds too slowly or too quickly, the user can control the amount of light from the light emitting components 5 by the first dial 7a during the irradiation.
The user sets the length of hair by the second dial 7b of the dimmer 7. It will be set “LONG” if the hair is long, and set “SHORT” if the hair is short. The irradiation range and angle of the light emitting components 5 are determined in accordance with the set length of hair.
(Effects)
(1) The photoirradiation hair dyeing device 10 of the present embodiment dyes hair by irradiating light to hair to which the hair dyeing agent is applied. The photoirradiation hair dyeing device 10 comprises: the hood 1, having the opening portion 1a through which a user's head is inserted and the internal surface 1b; the supporting portion 2, holding the hood 1 in midair; the light emitting components 5 arranged on the internal surface 1b of the hood 1.
According to the photoirradiation hair dyeing device 10 of the present embodiment, the user has no need to held the photoirradiation hair dyeing device 10 during the irradiation, because the hood 1 is held in midair. Therefore, the user's load will be reduced since the user's hands will not be occupied by the photoirradiation hair device 10 while using it. The user can photoirradiation hair dye easily without the load.
(2) The supporting portion 2 includes: the base 22 to be placed on the floor, and the pillar 21 standing on the base 22. By this structure, the photoirradiation hair dyeing device 10 is a stand type, and self-standing on the floor. The user can move the photoirradiation hair dyeing device 10 to any position. The user can use the photoirradiation hair dyeing device 10 at desired place indoor.
(3) The hood 1 is substantially truncated pyramid shape, substantially truncated cone shape, or substantially hemispherical shape, and the light emitting components 5 are arranged on the entire of the internal surface 1b at equal intervals.
The hood 1 has substantially truncated pyramid shape, substantially truncated cone shape, or substantially hemispherical shape that is a similar shape to the user's head, so that a perimeter of the head surrounded by the hood 1 has equal distance from the internal surface 1b of the hood 1. In addition, the light emitting components 5 are arranged on the entire internal surface 1b at equal intervals, so that the head has equal distance from the light emitting components 5. Therefore, in the present embodiment, uniform light is irradiated simultaneously to the entire head.
The light can be irradiated to a broad range simultaneously according to the present embodiment. In comparison, in the case of the brush shaped photoirradiation hair device, because an area of the brush is limited, there is a need to change a position of irradiation plural times according to the irradiation area of the brush so as to dye the entire hair. Quite a long time will be needed to dye the entire hair. Also, the irradiation time would vary in each part, thereby causing uneven dyeing. In contrast, according to the present embodiment, the dyeing time will be shortened significantly for there is no need to dye each part in turn like the brush shaped device.
Furthermore, by irradiating to broad range simultaneously, a variation of the irradiation time for each part would be suppressed, an irregularity will decrease. The irregularity will also decrease because light is irradiated equivalently to each parts simultaneously. In particular, the entire hair will be surrounded by the hood 1 when the hair of the user, for example men, is short. Therefore, equivalent light will be irradiated simultaneously to the entire hair. The photoirradiation hair dyeing can be performed with much less irregularity.
(4) The angle adjusting mechanism 4 adjusting the angle of the opening portion 1a of the hood 1 against the floor is provided. The user can set the hood 1 at desired angle position by adjusting the angle. For example, when setting the angle of the hood 1 such that the opening portion 1a is parallel to the floor, the user can use the photoirradiation hair dyeing device 10 by inserting his/her head with his/her upper body standing straight. By setting the angle of the hood 1 such that the opening portion 1a is tilted against the floor, the user can use the photoirradiation hair dyeing device 10 by inserting his/her head in a reclining position such as when leaning on a backrest of a chair. The user can use the photoirradiation hair dyeing device 10 indoor at free pose without any special operation.
The user's head can be positioned to be placed at the center of the space S surrounded by the internal surface 1b of the hood 1. The light emitting components 5 arranged on the internal surface 1b of the hood 1 are at equal distance and not in contact with any of the hair. For example, in the case where the photoirradiation hair dyeing device is brush shaped or comb shaped, when the undried photoirradiation hair dyeing agent contacts directly to pins, the photoirradiation hair dyeing agent applied to the hair would be removed, causing the irregularity. Also, if the photoirradiation hair dyeing agent adheres to the photoirradiation hair dyeing device, it might cause the photoirradiation hair dyeing device malfunction. To prevent these problems, the user have to wait until the photoirradiation hair dyeing agent dries, causing an excessive waiting time losing the simplicity of the photoirradiation hair dyeing agent. However, in the present embodiment, there is no need to wait the photoirradiation hair dyeing agent to dry, and the excessive waiting time will not occur.
The tightening nut 3 as the height adjusting mechanism to adjust the height of the supporting portion 2 is provided. The user can adjust the height of the hood 1 of the photoirradiation hair dyeing device 10 at desired position by adjusting the height of the supporting portion 2. The user can use the photoirradiation hair dyeing device 10 indoor at free pose, regardless of a height of the chair or the user without any special operation.
(6) The dimmer 7 adjusting the intensity of light, irradiation angle and range of by the light emitting components 5 is provided. The user can control a processing speed of the hair dyeing by adjusting the intensity of light irradiated. The user can adjust the color and the end timing of the dyeing personally. The user can control a part of the hair to be irradiated by adjusting the angle or range of light irradiated. The user can adjust the parts to be dyed personally.
(7) The pillar 21 includes the upper pipe 21b bent in the middle. By this structure, an angle moving range of the opening portion 1a of the hood 1 against the floor is broader. For example, by bending the upper pipe 21, the hood 1 will not abut the supporting portion 2 even when the opening portion 1a is set parallel to the floor.
(8) The light emitting components 5 can be compact by using LED, and thus whole size of the photoirradiation hair dyeing device 10 can also be compact.
(9) When the second dial 7b is set “LONG”, all light emitting components 5 will irradiate light to the entire head. Light reaches to the lower part since the irradiation angle of the light emitting components 5 around the opening portion 1a is directed towards the floor. Thus, in a case when one having long hair uses the photoirradiation hair dyeing device 10, a tip of the hair sticking out from the space S inside the hood 1 can be irradiated. When the second dial 7b is set “SHORT”, the light emitting components 5 around the opening portion 1a will not irradiate light, and light will be irradiated mainly on the top of the head. This prevents the user's neck, where the hair does not grow and are not to be irradiated, from irradiation, thus the user's discomfort due to light and heat can be reduced.
(10) The heat vent is provided to release the heat of the light emitting components 5 outside. This prevents an excessive increase of temperature of the hood 1 caused by the heat of the light emitting components 5, and prevents the user from accidents such as burn when contacted with the hood 1.
(11) By the structure mentioned above, the photoirradiation hair dyeing device 10 of the present embodiment can photoirradiation dye hair easily in a short time when the user wants to dye hair, even in bad weather such as rainy day or cloudy day. The photoirradiation hair dyeing will proceed fast by sunlight in a sunny day, but will take several days in a bad weather. The photoirradiation hair dyeing device 10 of the present embodiment enables to photoirradiation hair dye gradually by natural light, after proceeding hair dyeing using the photoirradiation hair dyeing device 10 for a short time before going outside even in a bad weather.
Second Embodiment(Structure)
The second embodiment has a same basic structure as the first embodiment. As illustrated in
The light diffuse reflecting components 6 are sheets to diffuse reflect light. As example of such sheet, a blind sheet such as optically transparent substrates having microscopic irregularities on surface thereof can be employed. A known light diffusion sheet can also be employed.
The light emitting components 5 are arranged on the internal surface 1b of the hood 1 at equal intervals, and the light diffuse reflecting components 6 are arranged on the remaining parts of the internal surface 1b of the hood 1 at equal intervals. As illustrated in
(Effect)
(1) The light diffuse reflecting components 6, which diffuse light of the light emitting components 5, are arranged on the internal surface 1b of the hood 1 at equal intervals. Light of the light emitting components 5 will diffuse and be reflected, so that equivalent light is irradiated to the entire hair even when reducing the number of the light emitting components 5. By reducing the number of the LEDs, cost for manufacturing the photoirradiation hair dyeing device 10′ will be cut down. Also, the amount electric power used will be reduced, and cost for using photoirradiation hair dyeing device 10′ will be cut down.
By diffusing and reflecting the direct light of LED or fluorescent lumps, the light becomes like natural light. It will reduce a glare, resulting in an increase of comfort when using the photoirradiation hair dyeing device 10′.
(2) The light diffuse reflecting components 6 are arranged around the opening portion 1a of the hood 1, and the light emitting components 5 are arranged around the apex portion 1c of the hood 1. By arranging the light emitting components 5 around the apex portion 1c of the hood 1, the light reflecting components 6 reflects and diffuses light effectively. cl Other Embodiments
The embodiment of the present disclosure is explained above, but various omissions, replacements, and modifications can be made thereto without departing from the broadest scope of the present disclosure. In addition, such embodiments and examples thereof should be within the scope of the present disclosure, and also within the scope of the disclosure as recited in appended claims and the equivalent range thereto.
In addition to above mentioned embodiments, a bottom of the base 22 may have a caster. It will be easy to move the photoirradiation hair dyeing device 10 and 10′.
In the above embodiment, the upper pipe 21b is bent in the middle, however it is not limited to the structure. For example, the pillar 21 may stand straight from the base 22, and the lower pipe 21a may be bent in the middle.
In the above embodiment, the tightening nut 3 functions as the height adjusting mechanism as well as the fixture, however it is not limited to the structure. For example, the height adjusting mechanism and the fixture may be on different elements.
In the above embodiment, the hood 1 is substantially truncated cone shaped, however it is not limited to the structure. For example, the hood 1 may be a shape similar to the user's head such as substantially truncated pyramid shape, or substantially hemispherical shape.
In the above embodiment, the light emitting components 5 are arranged on the entire internal surface 1b of the hood 1 concentrically to the apex as a center, however it is not limited to the structure. For example, the light emitting components 5 may cover entire internal surface 1b, be in checker pattern, be in spiral pattern with the apex of the hood 1 as a center, be in horizontal stripe pattern parallel to an edge of the opening portion 1a, or be in vertical stripe pattern vertical to the edge of the opening portion 1a. If the components are arranged in these patterns, the light emitting components 5 can be arranged equivalently to the whole surface at the same time reducing the number of the light emitting components 5.
In the above embodiment, the supporting portion 2 comprises the pillar 21 and the base 22 for holding the pillar 21, wherein the pillar 21 holds the hood 1 on the upper side, however it is not limited to the structure. For example, the supporting portion 2 may be a pillar or cable suspended from a ceiling and extended towards the floor, and suspends the hood 1 in midair.
In the above embodiment, the dimmer 7 includes: the first dial 7a for adjusting the intensity of light; and the second dial 7b for adjusting the irradiation range and angle of light in accordance with the length of hair, however the dimmer 7 may include only either one of the dials.
In the above embodiment, the second dial 7b adjusts the irradiation range and angle of light in accordance with the two types of the length of hair “SHORT” and “LONG”, however it is not limited to the structure. For example, it can be set adjustable by dividing the length of hair into five types. Furthermore, the users may set each irradiation range and angle individually. In this case, when the user wants to dye only the top of the hair, he will adjust the dimmer 7 so that only the light emitting components 5 around the apex portion 1c of the hood 1 irradiates light.
In the second embodiment above, the light emitting components 5 are set around the apex portion 1c of the hood 1 concentrically to the apex of the hood 1 as a center, and the light diffuse reflecting components 6 around the opening portion 1a concentrically to the apex of the hood 1 as a center, however it is not limited to the structure. For example, the light emitting components 5 and the light diffuse reflecting components 6 can be in checker pattern, be in horizontally stripe pattern alternately parallel to the opening portion 1a, or vertically stripe pattern alternately.
