Abstract
The invention relates to a shaving apparatus which is characterized in that a laser beam (13) serves as the cutting means, and to a method of removing body hairs by means of such a shaving apparatus. The shaving apparatus comprises a shear plate (11) with an entry slot (24). The laser beam (13) is generated by a device (12), severs the hair in the proximity of the entry slot, and is preferably reflected from the shear plate and detected by a photo-cell (18). The shaving apparatus in accordance with the invention enables body hairs to be severed without irritating the skin.
Claims10
A shaving apparatus comprising a housing (10) and a shear plate (11) with a hair entry slot (24) wherein inside the housing (10) there is provided a device (12) for generating a laser beam (13) which acts as a cutting means and which impinges on the inner side of the shear plate (11) in the proximity of the entry slot (24) where it acts upon and severs the hair, said laser beam (13) impinging on said shear plate (11) and being reflected along the entry slot (24) in a reflecting zone of incidence (23) on the shear plate (11).
A shaving apparatus comprising a housing (10) and a shear plate (11) with a hair entry slot (24) wherein inside the housing (10) there is provided a device (12) for generating a laser beam (13) which acts as a cutting means and which impinges on the inner side of the shear plate (11) in the proximity of the entry slot (24) where it acts upon and severs the hair, there being an angle of incidence .alpha. between the laser beam (13) and the shear plate (11) of between 50.degree. and 85.degree..
A shaving apparatus comprising a housing (10) and having upper and lower housing sections and a shear plate (11) with a hair entry slot (24) wherein inside the housing (10) there is provided a device (12) for generating a laser beam (13) which acts as a cutting means and which impinges on the inner side of the shear plate (11) in the proximity of the entry slot (24) where it acts upon and severs the hair, said upper housing section (14) engaging over said lower housing section and the lower housing section being guided in the upper housing section so as to be axially movable against the force of a spring (15).
A shaving apparatus comprising a housing (1) and a shear plate (11) with a hair entry slot (24) wherein inside the housing (1) there is provided a device (12) for generating a laser beam (13) which acts as a cutting means and which impinges on and is reflected along the inner side of the shear plate (11) in the proximity of the entry slot (24) where it acts upon and severs the hair, a fan (16) being arranged in the housing.
A shaving apparatus comprising a housing (10) and a shear plate (11) with a hair entry slot (24) wherein inside the housing (10) there is provided a device (12) for generating a laser beam (13) which acts as a cutting means and which impinges on the inner side of the shear plate (11) in the proximity of the entry slot (24) where it acts upon and severs the hair, the generated laser beam (13) being planar and impinging on the shear plate (11) and is reflected along a line parallel to the edge of the entry slot (24).
