Description

  The present invention relates to a handpiece for an optical beauty device, and more specifically, a plurality of convex lens elements each having a flat surface on one side and a convex surface on the other surface are arranged in a vertical and horizontal plane, and each of the convex lenses is passed through each of them. The present invention relates to a hand piece of an optical beauty device that can obtain a high hair removal effect in a short period of time even by low output by irradiating light.

  2. Description of the Related Art Conventionally, hair removal beauty equipment is one that transmits body hair by an electrical method, one that dissolves body hair by a chemical method, and one that cleans body hair by an optical method (hereinafter referred to as an optical beauty device). ) Etc. are well known. The optical beauty device is a device that emits light from a light source and irradiates the hair removal portion with light to instantaneously clean the hair (see, for example, Patent Document 1). In this respect, it is also effective for anti-stain and freckles and other beautiful face.

  The optical beauty device is roughly divided into an apparatus main body that performs control of causing a light source to emit light at predetermined intervals, and a handpiece that directly irradiates light on a hair removal part and a face part. And the filter which permeate | transmits the irradiation light of a predetermined wavelength is arrange | positioned in front of the light source, and transmission of unnecessary irradiation light is restrict | limited. There are various types of filters depending on the cosmetic use. For example, a red filter is used for hair removal and a yellow filter is used for a beautiful face. Therefore, it is necessary to replace the filter according to the cosmetic use.

  This filter replacement operation affects the safety of the optical beauty device depending on the skill level of the operator and the attention at that time. For example, there is a problem in that there is a distinction between the front and back of the filter, but it is difficult to distinguish the filter, and it is difficult to confirm whether the filter is firmly fitted in the groove when the filter is attached. For this reason, if the operator installs the filter incorrectly, there is a problem that causes leakage of irradiated light and leads to burns for customers. In addition, the filter is a consumable item, and the softening / solubilization of the filter due to the heat generated when the handpiece is used, and the abrasion due to wear / removal wear. And the irradiation light leakage which generate | occur | produces by the factor had the problem which leads to a customer's burn.

  Furthermore, the optical beauty device is classified into a professional beauty device used by a specialist and a home beauty device that is easily used at home. Professional beauty equipment needs to perform hair removal treatment over a wide area at high speed, and a method using a laser beam is generally used. However, the state of the skin surface is detected by an image sensor, and image processing is performed on the image. After recognizing the position of the body hair, the laser beam angle is changed to align each body hair and irradiate, so the treatment time for hair removal becomes longer, and the laser beam is Irradiation may lead to burns and other accidents (see, for example, Patent Document 2).

  Photo epilation means that light such as strobolite is applied to a special glass filter that does not allow light shorter than a certain wavelength to pass through, and light centered on a wavelength (400 to 1200 nm) that is easily absorbed by melanin. In this method, permanent hair removal is achieved by irradiating the hair root with the light and destroying the regenerated tissue around the hair follicle. A medical laser is a light beam having the same wavelength and the same phase and having a high degree of straightness, but the light used for photohair removal is a composite wavelength in which light having a plurality of wavelengths is mixed, and is diffused light. Due to its diffusibility, if it is too close to the skin, it may cause burns and other troubles.
