DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photo epilation device,
More particularly, the present invention relates to an optical hair removal device that performs hair removal by condensing light near a hair root.

[0002]

2. Description of the Related Art A conventional photo-epilation device includes a photo-epilation device that collects one laser beam near the hair root and removes hair, and a light that collects light emitted from one incandescent lamp near the hair root and removes hair. There is a hair removal device.

[0003] However, the conventional photo-epilation device has a single light-emitting source, and performs hair removal by condensing light emitted from the light-emitting source and applying the light to the vicinity of the hair root.

[0004]

For this reason, hair removal is performed only at one point where light is collected, and it is not efficient when hair removal is required over a wide area, and it takes time for hair removal. There was a point.

[0005] It is an object of the present invention to provide a photo-epilation device that facilitates hair removal over a wide area using light emitted from a plurality of light-emitting sources.

[0006]

According to the present invention, there is provided a photo-epilation device having a slit formed at a distal end thereof, and a probe for bringing a surface of a predetermined range including the slit into contact with skin, and a probe in the probe. Opposite to the slit, and a cylindrical lens provided at a predetermined distance from the slit, each having a filament formed in a linear shape and having a plurality of incandescent lamps with hemispherical lenses having a hemispherical lens at the tip A plurality of incandescent lamps with hemispherical lenses are provided in the probe such that the filaments of the incandescent lamps with a plurality of hemispherical lenses are located on a straight line, and the filaments located in a straight line face the slits with the cylindrical lens interposed therebetween. A light source is provided at an interval, and a power supply device for supplying power to the light source is provided.

According to the photo-epilation device according to the present invention, the light from each of the incandescent lamps with a hemispheric lens constituting the light source is condensed almost elliptically by the hemispheric lens, Furthermore, since each filament of the incandescent lamp with a plurality of hemispheric lenses is arranged in a straight line, the light from the incandescent lamp with a plurality of hemispheric lenses has an elliptical major axis based on the light from the adjacent incandescent lamp with a hemispheric lens. Partly overlaps in the direction to form a long ellipse with a long diameter,
The light that is linearly imaged by the cylindrical lens and is linearly imaged by the cylindrical lens is condensed from the skin through the slit, for example, to the position of the hair root that has entered about 5 mm, and the hair root is heated and the slit is formed. Is performed over the area of the hair.

Accordingly, the hair can be efficiently removed over a wide range by sequentially moving the probe.

In the photo-epilation apparatus according to the present invention, the temperature near the incandescent lamp with a hemispheric lens is detected, and when the temperature near the incandescent lamp with a hemispheric lens reaches a predetermined temperature or higher, power is supplied to the incandescent lamp with a hemispheric lens. May be provided with a temperature switch for shutting off.

In the photo-epilation device according to the present invention, since the power supply is cut off when the temperature inside the probe exceeds a predetermined temperature due to the provision of the temperature switch, the plurality of incandescent lamps with hemispherical lenses emit light intermittently. That is, the temperature in the probe is suppressed to a predetermined temperature, and the light emission is intermittent, so that overheating at the position of the hair root can be prevented.

In the photo-epilation device according to the present invention, duty ratio setting means for selectively setting the duty ratio of power supply to the incandescent lamp with a hemispheric lens may be provided.

[0012] In the photo-epilation device according to the present invention, the duty ratio setting means is provided, so that the duty ratio can be selected according to individual differences. It can be conveniently applied to persons.
