Detailed Description

Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed descriptions of well-known matters or repeated descriptions of substantially the same structure may be omitted.

Furthermore, the figures and the following description are provided to enable those skilled in the art to fully understand the present invention and are not intended to limit the subject matter recited in the claims.

(Embodiment)

As shown in fig. 1,2, and 3, in the beauty device 1 of the present embodiment, a control circuit unit 10, a cooling unit 8, and a capacitor 9 for emitting light from a xenon tube 130 (see fig. 5) are disposed inside two divided cases 4a and 4b of a main body 1a. The irradiation unit 12 is provided inside the fitting 160 attached to the upper part of the cases 4a and 4 b. The fitting 160 is detachably attached to the main body 1a.

The portion of the main body 1a on the opposite side to the portion on which the fitting 160 is mounted is a grip portion gripped by a user, and the power cable 7 is led out from the protruding end portion of the grip portion.

Next, a schematic structure of the illumination unit 12 and the cooling unit 8 will be described with reference to fig. 3, 4, and 5.

In the irradiation unit 12, a reflection plate 131 through which a xenon tube 130 as a light source for emitting light is inserted is disposed inside a lamp housing 124 shown in fig. 5. The outer peripheral surface 130a of the xenon tube 130 is biased by the light source holding members 133 engaged with both end portions of the xenon tube 130 so as to be always in contact with the curved surface portion 131b of the reflection plate 131. The conductive tape 132 disposed between the xenon tube 130 and the reflection plate 131 and the light source holding member 133 is a trigger portion for causing the xenon tube 130 to emit light.

The upper surface of the xenon tube 130 is covered with a UV filter, i.e., a filter 122 that shields ultraviolet rays, and the filter 122 is positioned between the elastic member 123 of the central opening and the lamp housing 124 at the outer peripheral portion.

The transparent member 121 made of glass is held on the upper surface by the glass case 125, and the lower surface of the transparent member 121 is elastically contacted with the filter 122 by the elastic member 123. By bringing the transparent member 121 and the filter 122 into contact with each other via the elastic member 123, dew condensation caused by a temperature difference generated between the transparent member 121 and the filter 122 can be suppressed. The glass envelope 125 is fixed to the lamp housing 124 by the screw 14.

Next, the cooling unit 8 is described in detail. In the cooling unit 8, the radiator 83 is disposed inside a case composed of 3 members, i.e., the 1 st duct case 140, the 2 nd duct case 141, and the 3 rd duct case 142. The 2 nd air path casing 141 is fixed to the 1 st air path casing 140 by the screw 22, and is fixed to the 3 rd air path casing 142 by the screw 33. The heat pipe 81 is integrally fixed to the radiator 83.

A radiator 83 is provided on the upper surface of the fan 150 held by the 2 nd and 3 rd duct cases 141 and 142, and the radiator 83 is held by the 2 nd and 1 st duct cases 141 and 140. The heat pipe 81 is exposed to the outside of the case formed by the duct cases 140, 141, and 142, and is in contact with a peltier element 80 described later via the heat radiation plate 82.

The lamp housing 124 is fixed so as to sandwich the 1 st air path case 140 and the 2 nd air path case 141, and the heat radiation plate 82 integrally fixed to the heat pipe 81 is fixed to the glass case 125 by the screw 55. Thereby, the irradiation unit 12 and the cooling unit 8 are integrated.

A hole 1251 is opened at one side of the glass case 125, the transparent member 121 is exposed through the hole 1251, and the peltier element 80 is in contact with the exposed portion of the transparent member 121. For heat dissipation of the peltier element 80, the heat dissipation plate 82 is brought into contact with the surface of the peltier element 80 on the opposite side to the surface with which the transparent member 121 is in contact. Further, a lubricant or a sheet having thermal conductivity may be interposed between the peltier element 80 and the transparent member 121 and between the peltier element 80 and the heat sink 82.

Next, cooling of the filter 122 is detailed. As shown in fig. 7, wind from the fan 150 is blown to the reflection plate 131 through the 1 st wind path 143, and is divided into the 2 nd wind path 144 and the 3 rd wind path 145. The 2 nd air duct 144 passes through a gap between the filter 122 and the concave portion 131a (see fig. 15 to 17) provided at the upper portion of the reflection plate 131, and passes to the 4 th air duct 146 side, and merges with the 3 rd air duct 145. On the other hand, the 3 rd air passage 145 merges with the 2 nd air passage 144 through the lower portion of the reflection plate 131. The xenon tube 130 in contact with the curved surface portion 131b of the reflecting plate 131 is also cooled by cooling the reflecting plate 131 by the air flowing through the 2 nd air passage 144 and the 3 rd air passage 145 provided around the reflecting plate 131, and the filter 122 is also cooled. The 1 st air passage 143, the 2 nd air passage 144, the 3 rd air passage 145, and the 4 th air passage 146 constitute an air circulation air passage through which air circulates.

As shown in fig. 2 and 3, the air intake 5 leading to the 1 st air path 143 introduces air from a gap provided between the 1 st casing 4a and the 2 nd casing 4 b. The 2 nd housing 4b is fixed to the 3 rd housing 4c having a frame-like portion by a screw 11, and the 3 rd housing 4c is fixed to the 1 st housing 4a using a hook 13.

Then, air is introduced into the 1 st air passage 143 in the case constituted by the housings 4a, 4b, and 4c through the air inlet 5 (the gap provided between the 1 st housing 4a and the 2 nd housing 4 b) from the plurality of air inlet holes 44 provided in the 3 rd housing 4 c. On the other hand, the air in the 4 th duct 146 inside the case constituted by the cases 4a, 4b, and 4c is discharged from the plurality of exhaust holes 6 provided in the 1 st case 4 a. In addition, a dust collecting filter or a deodorizing filter may be provided in a case constituted by the housings 4a, 4b, and 4c, and the dust collecting filter or the deodorizing filter may clean air when the air is sucked in from the air inlet 5 (a gap provided between the 1 st housing 4a and the 2 nd housing 4 b).

As for the optical path of the light, the light emitted from the xenon tube 130 passes through the filter 122, and UV (ultraviolet) light which stimulates the skin is shielded and irradiated to the skin through the transparent member 121. As described above, the peltier element 80 is in contact with the side surface of the transparent member 121, and the transparent member 121 is cooled by the peltier element 80, so that the skin, which is the portion to be irradiated, is also cooled at the same time, and light can be irradiated while suppressing stimulation of light.

In addition, the temperature of the surface of the peltier element 80 on the opposite side to the surface with which the transparent member 121 is in contact increases, and therefore the surface on the opposite side is brought into contact with the heat dissipation plate 82. Thereby, the peltier element 80 is cooled by the heat pipe 81 connected to the heat sink 83.

The fitting 160 is detachably attached to the main body 1a, and the fitting 160 protects the skin from the corners of the transparent member 121.

As shown in fig. 8, a light guide plate 170 fixed to the main body 1a is provided on the same plane as the skin contact surface 160b of the fitting 160. The light guide plate 170 is provided on the LED cover 180. The LED cover 180 covers an LED 182 as a light emitting element for detecting skin color and a light receiving element 181 for confirming skin contact, which are provided on the substrate 183. Therefore, the fitting 160 is formed with a transmission portion 160c, and the transmission portion 160c transmits light from the LED 182, so that the close contact of the skin surface with the skin contact surface 160b provided to the fitting 160 is detected.

The light receiving element 181 detects brightness of the use environment when the power of the main body 1a is turned on, and detects darkness when the skin contact surface 160b of the accessory 160 contacts the skin surface. When the light receiving element 181 detects darkness when the skin contact surface 160b of the accessory 160 contacts the skin surface, the LED 182 emits light, and the light receiving element 181 detects skin color based on the amount of reflected light. After recognizing whether or not the skin color is a skin color that can be irradiated, light is irradiated from the LED 182 to the skin surface. In this way, by detecting skin contact and skin color by the LED 182 and the light receiving element 181, the extra area of the skin contact surface 160b of the accessory 160 can be reduced.

Fig. 9, 10 and 11 are embodiments of the fitting 160. In this embodiment, as described above, the light guide plate 170 fixed to the main body 1a is provided on the same plane as the skin contact surface 160b of the attachment 160.

Fig. 12, 13 and 14 show an example of the fitting 161 having different areas of the irradiation parts. In this embodiment, the fitting 161 is higher in height than the fitting 160 shown in fig. 9 to 11, and the transparent member 121 is also located away from the skin contact surface 161 b. As shown in fig. 14, the area of the irradiation port 161a is also larger than the area of the irradiation port 160a of the fitting 160 shown in fig. 11. Thus, even in a region or the like where the density of hair is small and the irritation is relatively small, the irritation does not need to be suppressed by cooling, and therefore, the cosmetic behavior can be performed by using less irradiation in accordance with a large area of the irradiation portion. The fitting 161 is formed with a transmission portion 161c, and the transmission portion 161c transmits light from the LED 182, so that the close contact of the skin surface with the skin contact surface 161b provided on the fitting 161 is detected. Further, since the light guide rod 171 is fixed to the attachment 161 and is in contact with the light guide plate 170 fixed to the main body 1a, skin contact and skin color detection can be performed in the same manner as the attachment 160 shown in fig. 9 to 11. The LED 182 may be used to determine any one or more of the skin contact degree, the skin contact area, and the skin condition, or any one or more of the skin color, the skin texture, the skin age, the skin moisturization degree, and the skin fat degree.

Although not shown, a plurality of detection switches are provided in the main body 1a, and protrusions are provided in the fittings 160 and 161 of different types, respectively, so that at least one of the plurality of detection switches is pressed. The number and arrangement positions of the protrusions are different depending on the type of each fitting 160, 161. Therefore, when the fittings 160 and 161 are attached to the main body 1a, the above-described protruding portions press the detection switch, and thus the types of the attached fittings 160 and 161 can be detected based on the pressed detection switch.

The reflecting plate 131 is described in detail below with reference to fig. 15, 16, and 17.

As shown in fig. 15 to 17, the irradiation port 160a side (upper side in the drawing) of the concave space 135 of the reflection plate 131 is opened. In addition, a concave curved surface of the reflecting plate 131 forming the concave space 135 becomes a reflecting surface 136. The reflecting plate 131 further includes a pair of wall portions 137 and 137 covering both sides of the concave space 135. The inner surfaces of the pair of wall portions 137, 137 may be reflective surfaces. A pair of wall portions 137, 137 are provided with through holes 138 through which both end portions of the xenon tube 130 serving as a tubular light source are inserted.

In the reflection plate 131, the xenon tube 130 is housed in the concave space 135 in a state where both ends protrude from the concave space 135 via the through-holes 138. Thus, a part of the light emitted from the xenon tube 130 is directed toward the irradiation port 160a from the upper opening of the concave space 135, and the other light is directed toward the irradiation port 160a via the upper opening of the concave space 135 after being reflected by the reflecting surface 136.

As shown in fig. 17, the reflection plate 131 is formed in a concave shape when viewed in the axial direction of the xenon tube 130. Specifically, the reflection plate 131 is formed in a shape protruding to the side opposite to the irradiation port 160a side. Thus, a curved surface portion 131b is formed at an end portion of the reflecting plate 131 on the side opposite to the irradiation port 160a side, and the curved surface portion 131b is in surface contact with the outer peripheral surface 130a of the xenon tube 130.

As shown in fig. 15 to 17, the concave portions 131a are provided in the upper portions of the pair of wall portions 137 and 137, respectively, so that a part of the air passage around the reflecting plate 131 (the 2 nd air passage 144) is formed.
