Embodiment Construction

[0049] figure 1 The first cutter assembly for dry razors known from US-B1-6,560,875 is shown. The assembly is used to oscillate along axis A-A and has a plurality of arcuate cutter elements 101. Therefore, the arcuate cutter elements 101 are spaced apart along the length of the carrier 201 and arranged parallel to each other. A gap is provided between each adjacent pair of cutters, and the hair can extend into the gap during use so as to pass through the carrier 201 and thereby cut the hair by the oscillatory movement of the cutter element 101. It is also possible to provide a metal foil screen (not shown) between the user's skin and the cutter 101, which has holes large enough for hair to pass through, for being cut by the cutter 101, while protecting the user's skin.

[0050] figure 1 The assembly is machined from a single piece of metal, which results in high manufacturing costs. In addition, without further increasing the manufacturing cost, the cutting angle of each cutte...

Abstract

A cutter assembly for a dry shaver, the cutter assembly including an elongated carrier member (221) and a cutter element (1210) having a plurality of turns forming a spiral, each turn being The rings each have an arcuate cutting portion (1211) and an arcuate fixing portion sequentially along the helical direction; the carrier member is disposed generally parallel to the axis (D-D) of the cutter element; and the carrier member contacts and supports The cross-section of the helical coil of the cutter element (1210) is triangular or rhombus-shaped, and the cutting portion becomes a free-spanning arch.

Description

Technical field [0001] The present invention relates to a cutter assembly for an electric shaving device and a method of manufacturing such an assembly. Background technique [0002] Traditionally, shaving devices are divided into wet razors and dry razors. Wet razors usually involve dragging one or more razor-sharp blades across the surface to be shaved along a route at right angles to the edge of the blade itself in the presence of lubricating foam or fluid. On the other hand, a dry razor usually includes many cutting elements that are moved at high speed by an actuating mechanism (usually an electric motor) in a rotary or linear reciprocating motion relative to the surface to be shaved. This type of dry razor is complicated and costly, and it is difficult to achieve the shaving performance of a wet razor. [0003] Various assemblies for reciprocating along an axis at right angles to the shaving direction and including a plurality of cutting edges extending substantially parall...
