Problems solved by technology

If the pressing force is high, the skin bends more, resulting in a very smooth skin surface, but the high contact force between the blade and the skin surface can also make the skin feel uncomfortable

Embodiment Construction

[0020] Such as figure 1 The illustrated embodiment of the shaver of the present invention is a wet shaver, and includes a shaving head 1 that is detachably connected to a handle 3 by a connecting mechanism not shown in the figure. The shaving head 1 is equipped with three mutually parallel blades 5, and each blade has a cutting edge 7 extending perpendicular to the shaving direction X of the shaving head. Such as figure 1 As shown in and 2, the blade 5 is fixed on the sub-frame 9 of the shaving head 1. The two skin support members 11 and 13 are also fixed on the sub-frame 9. Seen from the shaving direction X, the skin support members also extend perpendicular to the shaving direction X and are respectively arranged at the front and rear of the blade 5. The skin supports 11, 13 each include a skin support surface 15 extending substantially within an imaginary contact surface 17, wherein the shaving head 1 contacts the skin surface to be shaved during operation. The shaving head 1...

Abstract

The invention relates to a shaving device which comprises a shaving head (1) having at least one cutting blade (5) and two skin-supporting members (11, 13), said cutting blade comprising a cutting edge (7) extending perpendicularly to a shaving direction of the shaving head, and said skin-supporting members, viewed in the shaving direction, being arranged, respectively, in front of and behind said cutting blade, and defining a contact surface between the shaving head and a skin surface (53) to be treated. The cutting blade and the skin-supporting members are mounted to a sub-frame (9), which is coupled to a main frame (19) and can be displaced with respect to said main frame against a spring force (FS). According to the invention, the main frame comprises two further skin-supporting members (21, 23) which, viewed in the shaving direction, are arranged, respectively, in front of and behind the sub-frame and extend substantially in said contact surface. As a result, a contact force (FC) between the skin surface and the skin-supporting members of the sub-frame and hence a skin curvature (w2) between the skin-supporting members of the sub-frame, i.e. at the location of the cutting member, is mainly determined by the value of said spring force and, accordingly, substantially independent of a pressure force (FP) exerted by a user to press the shaving head against the skin surface.

Description

Technical field [0001] The invention relates to a razor with a shaving head. The shaving head includes at least one blade and two skin support members. The blade has a cutting edge perpendicular to the shaving direction of the shaving head. From the shaving direction, the skin The supports are arranged at the front and the back of the blade and extend substantially within the contact surface. When in use, the shaving head contacts the surface of the skin to be shaved, and the blade and the skin support are fixed on the sub-frame. It is connected to the main frame and is displaced relative to the main frame against spring force. [0002] The invention also relates to a shaving head which can be applied to the shaver of the invention. Background technique [0003] A shaver of the type mentioned in the first paragraph is disclosed in WO-A-97 / 26119. The shaving head of this known razor includes two mutually parallel blades, which are arranged between two skin supports when viewed fro...
