Abstract
A hair cutting device of the present disclosure comprises an optical waveguide and a holding member that holds the optical waveguide. The optical waveguide comprises a light irradiator. The light irradiator irradiates hair protruding from skin with light to cut the hair. The holding member holds the optical waveguide in such a way that the light irradiator is exposed from at least one surface. As a result, even when the hair or the skin comes in contact with the light irradiator, misalignment or the like of the optical waveguide hardly occurs. This results in the improved hair cutting device being provided.
Claims14
A hair cutting device, comprising:
- an optical waveguide;
- and
- a holding member which holds the optical waveguide,
- wherein:
- the optical waveguide comprises a light irradiator configured to irradiate hair protruding from a skin with light to cut the hair,
- the holding member holds the optical waveguide in such a way that light irradiator is exposed from at least one face of the holding member,
- the holding member comprises a base and an adhesive member that bonds the optical waveguide to the base,
- a refractive index of the adhesive member is lower than a refractive index of the light irradiator,
- the adhesive member directly and physically contacts the light irradiator and restricts an amount of light leakage from the light irradiator, and
- the holding member holds the optical waveguide in such a manner that the light irradiator is exposed from at least one face of the holding member by exposing a part of optical waveguide from the adhesive member.
