  As shown in FIG. 1, the beauty device according to the present embodiment includes a beauty device body 1 and a light irradiation device 2 that irradiates a user's skin with pulsed light (light whose intensity is alternately switched). Yes.

  The beauty device main body 1 extends in the height direction and is configured to stand on its own. A support column 11 that can be moved back and forth in the height direction is attached to the upper part of the beauty device main body 1. The light irradiation device 2 is attached to the upper end portion of the column 11. Therefore, the height position of the light irradiation device 2 can be adjusted by moving the support column 11 back and forth in the height direction.

  A power cord 12 is connected to the beauty apparatus main body 1. When the power cord 12 is connected to an external power source, electric power for driving the light irradiation device 2 is supplied.

  FIG. 2 is a cross-sectional view of the light irradiation device 2. FIG. 3 is a longitudinal sectional view of the light irradiation device 2.

  As shown in FIGS. 2 and 3, the light irradiation device 2 includes a housing 3, a light source 4, and an optical deflector 5.

  An irradiation port 31 for irradiating light from the light source 4 is provided on one surface of the housing 3. The irradiation port 31 is provided so as to extend in the longitudinal direction X of the housing 3. In the present embodiment, the irradiation port 31 is covered with a filter 32. Thereby, it is suppressed that a foreign material penetrates into the inside of the housing 3. The filter 32 is made of, for example, polycarbonate.

  In the present embodiment, the filter 32 is configured to block light having a wavelength of 380 nm or less. Thereby, it is suppressed that a user's skin is irradiated with an ultraviolet-ray. Note that the filter 32 may be configured to reduce the transmittance of visible light. Thereby, the glare of the light irradiated from the irradiation port 31 can be suppressed.

  A plurality of air supply / exhaust holes 33 are provided at both ends in the longitudinal direction X of the housing 3. In addition, a fan 6 which is an example of a blower is provided inside the housing 3. The fan 6 is accommodated in a fan case 7 disposed on one end side in the longitudinal direction X of the housing 3. The fan 6 is driven by being supplied with power through the power cord 12. By driving the fan 6, the air inside the housing 3 is exhausted through the plurality of air supply / exhaust holes 33 and the outside air is sucked into the housing 3. As a result, the air inside the housing 3 is ventilated, and the temperature of the device is prevented from rising excessively.

  A holder 34 is attached inside the housing 3 so as to extend in the longitudinal direction X of the housing 3. As shown in FIG. 3, the holder 34 has a U-shaped cross section. A reflection plate 8 is attached to the inside of the holder 34. As shown in FIG. 3, the reflecting plate 8 is formed in a U-shaped cross section, and is attached so as to face the inner surface of the holder 34 with a gap. The reflector 8 reflects at least a part of the light generated from the light source 4 to an optical deflector 52 described later. In the present embodiment, the reflecting plate 8 constitutes the inner surface of the housing 3.

  The light source 4 is arranged inside the reflecting plate 8 and is configured to irradiate light toward the irradiation port 31. In the present embodiment, the light source 4 is configured to irradiate diffused light toward the irradiation port 31. The light source 4 is, for example, an infrared lamp heater.

  The light deflector 5 is disposed in the housing 3 at a position closer to the irradiation port 31 than the light source 4. The optical deflector 5 is configured to refract the light generated from the light source 4 and change the emission direction of the light emitted from the irradiation port 31 with time.

  In the present embodiment, the optical deflector 5 includes a rotation shaft 51, an optical deflector 52, and a rotation motor 53 that is an example of a rotation drive source.

  The rotating shaft 51 is arranged so that the axial direction is parallel or substantially parallel to the extending direction of the light source 4. In the present embodiment, a pair of rotating shafts 51 are attached to both ends of the light deflector 52. One rotary shaft 51 is pivotally supported by the fan case 7 so as to be rotatable about the axis. The other rotating shaft 51 is connected to the output shaft of the rotating motor 53. In the present embodiment, the other rotary shaft 51 and the output shaft of the rotary motor 53 are integrated. The rotating shaft 51 is made of, for example, a stainless steel round bar.

  The light deflector 52 is attached to the rotating shaft 51 so as to extend in the axial direction. The light deflector 52 is configured to refract light generated from the light source 4. In the present embodiment, the light deflector 52 is formed of a triangular prism, as shown in FIG.

  The rotation motor 53 is disposed on the other end side in the longitudinal direction X of the housing 3. That is, the rotary motor 53 and the fan 6 are arranged at positions facing each other with the light deflector 52 interposed therebetween. The rotary motor 53 is driven by power supplied through the power cord 12. When the rotary motor 53 is driven, the rotary shaft 51 is rotated around the axis. Thereby, the light deflector 52 attached to the rotating shaft 51 is rotated around the axis, and the direction in which the light generated from the light source 4 is refracted changes with time. As a result, the emission direction of the light emitted from the irradiation port 31 changes with time.

  FIGS. 5A to 5D and FIGS. 6A to 6D are schematic diagrams illustrating how the emission direction of light emitted from the light irradiation device 2 changes with time. As shown in FIGS. 5A to 5D, the direction in which the light generated from the light source 4 is refracted by the light deflector 52 changes with time as the light deflector 52 rotates about the rotation shaft 51. Thereby, the emission direction (illuminance peak) of the light emitted from the light irradiation device 2 changes so as to reciprocate between the upper part and the lower part of the user's face, as shown in FIGS. As a result, a specific part of the user's face (for example, the side cheek of the user about 15 cm away from the light irradiation device 2) is irradiated with pulsed light in which strength is alternately switched as shown in FIG. Will be.

  The cosmetic device according to the present embodiment includes the light deflector 5 that refracts the light generated from the light source 4 and changes the emission direction of the light emitted from the irradiation port 31 with time.

Can do.

  Further, according to the beauty device according to the present embodiment, it is possible to irradiate the user's skin with pulsed light without changing the intensity of light generated from the light source 4. That is, it is possible to irradiate the user's skin with pulsed light simply by driving the light source 4 continuously, and there is no need to switch the light source 4 on / off.

  Further, according to the beauty device according to the present embodiment, the light deflector 52 is configured by a triangular prism. According to this configuration, the width of the intensity of the pulsed light applied to a specific part of the user can be increased with a simpler configuration.

  Further, according to the beauty device according to the present embodiment, the reflecting plate 8 constituting the inner surface of the housing 3 is configured to reflect at least part of the light generated from the light source 4 to the light deflector 52. Yes. According to this structure, it can suppress further that the energy of light stays in an apparatus, and can suppress further the temperature rise of an apparatus.

  The light deflector 5 may be configured to periodically change the emission direction of the light emitted from the irradiation port 31. For example, the rotation of the rotation motor 53 may be constant, and the optical deflector 52 may be configured to rotate at a constant speed. In this case, the user's skin can be irradiated with pulsed light whose intensity changes periodically.

  Further, the rotary motor 53 may be configured to be driven by reversing the direction of rotation of the rotary shaft 51 in the forward and reverse directions. That is, the light deflector 52 is not limited to being rotated in one direction (forward rotation direction), and may be configured to reciprocate by rotating in the forward rotation direction and the reverse rotation direction. Even in this case, the light generated from the light source 4 can be refracted, and the emission direction of the light emitted from the irradiation port 31 can be changed with time.

  In addition, it is preferable that the entire light deflector 52 is disposed inside the housing 3. According to this configuration, the light that has passed through the light deflector 52 can be focused on the irradiation port 31 by the reflecting plate 34 positioned between the light deflector 52 and the irradiation port 31, and is emitted from the irradiation port 31. It is possible to suppress excessive diffusion of light.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, in the above description, the filter 32 is provided so as to cover the irradiation port 31, but the present invention is not limited to this. The filter 32 is not necessarily provided, and the irradiation port 31 may remain open.

  In the above description, the light source 4 is configured to irradiate diffused light toward the irradiation port 31, but the present invention is not limited to this. For example, the light source 4 may be configured to irradiate a light beam toward the irradiation port 31. Even with this configuration, the user's skin can be irradiated with pulsed light.

  In the above description, the reflecting plate 8 is attached as a separate component inside the housing 3 and the reflecting plate 8 constitutes the inner surface of the housing 3. However, the present invention is not limited to this. For example, the housing 3 and the reflecting plate 8 may be integrally configured by the same member. Further, for example, at least a part of the light generated from the light source 4 may be reflected to the light deflector 52 by mirror-finishing the inner surface of the housing 3.

  In the above description, as shown in FIG. 4, the light deflector 52 is formed of a triangular prism. However, the present invention is not limited to this. For example, the light deflector 52 may be formed of a prism having a prismatic shape such as a quadrangular prism or a pentagonal prism. Further, the corners of the polygonal prism may be chamfered into an R shape, for example. Further, for example, as shown in FIG. 8, the light deflector 52 may be formed of an elliptic cylinder having light transparency. Also with these configurations, by rotating the light deflector 52 around the axis, the light generated from the light source 4 can be refracted, and the emission direction of the light emitted from the irradiation port 31 can be changed with time.

  Further, as shown in FIG. 9, the light deflector 52 may be formed of a light-transmitting gear-like member formed so that a plurality of teeth extend in the longitudinal direction on the outer peripheral surface of the cylinder. . According to this configuration, the light emitted from the light source 4 can be refracted and the emission direction of the light emitted from the irradiation port 31 can be changed with time by rotating the light deflector 52 by a smaller amount of rotation. .

  Further, as shown in FIG. 10, the light deflector 52 may be formed of a belt-like film member having a light transmission property wound spirally. Also with this configuration, by rotating the light deflector 52 around the axis, the light generated from the light source 4 can be refracted, and the emission direction of the light emitted from the irradiation port 31 can be changed with time.

  In the above description, the optical deflector 5 is composed of the rotary shaft 51, the optical deflector 52, and the rotary motor 53. However, the present invention is not limited to this. For example, the optical deflector 5 may include a vibration motor (not shown) that is an example of a vibration source that vibrates at least a part of the optical deflector 52 instead of the rotation shaft 51 and the rotation motor 53. Also with this configuration, the light deflector 52 is vibrated by the vibration motor, whereby the light generated from the light source 4 can be refracted and the emission direction of the light emitted from the irradiation port 31 can be changed with time. As a result, the user's skin can be irradiated with pulsed light.

  Further, as shown in FIG. 11, the light deflector 52 may be configured by bending a belt-like film member into a wave shape. According to this configuration, for example, the light deflector 52 is vibrated so that the top of the wave is displaced in the direction of the wave, so that the light generated from the light source 4 is refracted and the light emitted from the irradiation port 31 is reflected. The emission direction can be changed with time.

  Further, the light deflector 52 is not limited to a solid structure, and may have a hollow structure. Note that the amount of change that refracts the light generated from the light source 4 can usually be increased when the light deflector 52 has a solid structure.

  Further, as shown in FIG. 12A or 12B, the light deflector 52 has a liquid 52A and an internal space S1 larger than the volume of the liquid 52B, and a liquid container 52B that stores the liquid 52A in the internal space S1. May be provided. According to this configuration, for example, the liquid container 52B is vibrated by a vibration source to shake the surface of the liquid 52A, thereby refracting the light generated from the light source 4 and changing the emission direction of the light emitted from the irradiation port 31. Can change over time. The liquid container 52B may be formed of a hollow cylindrical body as shown in FIG. 12A or FIG.
