Embodiment 1

[0036] Such as figure 1 , figure 2 , Figure 5 As shown, the inner cutter of the razor in this embodiment includes a knife seat 100 and a knife body 200 connected with the knife seat 100. At least one group of radial arms 300 protrude from the outer periphery of the knife body 200, and the vertical direction of the radial arm 300 There is at least one set of knife arms 400 standing upright in the direction, and the knife arms 400 have at least one acute cutting edge 401 on them, and are radially arranged along the knife body 200 . The knife arm is arranged vertically along the radial arm, and is arranged radially along the knife body. When the inner knife and the outer knife cooperate to shave, the inner surface of the inner knife and the outer knife are more compact, and the inner surface of the inner knife and the outer knife are always parallel , to achieve a better shaving effect.

[0037] In this embodiment, multiple groups of radial arms 300 protrude from the outer p...

Embodiment 2

[0041] The main difference between this embodiment and Embodiment 1 is that a transverse arm is arranged on the radial arm. Such as image 3 , Figure 4 , Figure 5 As shown, the inner cutter of the razor in this embodiment includes a knife seat 100, and a knife body 200 connected to the knife seat 100. At least one group of radial arms 300 protrude from the periphery of the knife body 200, and the sides of the radial arms 300 Stretch transverse arm 500, radial arm 300 and transverse arm 500 all upright knife arm 400 in vertical direction; 500 erects the knife arm 400 in the vertical direction.

[0042] In this embodiment, multiple groups of radial arms 300 protrude from the outer periphery of the cutter body 200, and the radial arms 300 may be two groups, three groups, four groups, five groups or even more. 200, the vertical direction of each group of radial arms 300 is erected with two groups of knife arms 400, and the knife arms 400 extend vertically from the surface of...

Embodiment 3

[0046] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the structure of the acute cutting edge on the knife arm has changed. Such as Figure 6As shown, there are acute-angled cutting edges 401' on the opposite sides of the knife arm 400' along the radial direction, thereby forming a double-sided acute-angled cutting edge. A knife surface 402' is formed between the two acute-angled cutting edges 401', and the knife surface 402' faces The inner slope forms a relief groove 403', and the upper part of the knife arm 400' supporting the knife surface and the relief groove forms a knife neck 404', and the range of the acute angle β is between 20° and 45°. The advantage of the acute-angle cutting edge in this embodiment is that the cut beard can slide down from the knife relief groove formed inwardly on the knife face, so as to avoid accumulation on the knife face and affect shaving.

[0047] The knife arm in this embodiment can be applied to Embodime...

Abstract

The invention relates to the field of shavers, in particular to an inner clipper of a shaver, and aims to achieve good shaving effect during matching of the inner clipper and an outer clipper. The technical scheme includes that the inner clipper of the shaver comprises a clipper base and a clipper body connected with the clipper base; at least one group of axial arms extends out of the periphery of the clipper body; at least one group of clipper arms is erected in the vertical direction of the radial arms; at least one acute-angular clipping blade is arranged on each clipper arm, and the clipper arms are in radial arrangement along the clipper body. Compared with the prior art, the inner clipper has the advantages that the clipper arms are vertically arranged and are in radial arrangement along the clipper body to enable the inner clipper to be always parallel to the inner surface of the outer clipper, compact adhesion is realized, beard clipping efficiency is improved, and good shaving effect is achieved; at least one acute-angular clipping blade is arranged on each clipper arm, and the inner clipper rotates along different directions to enable the clipping blades to work alternately, so that abrasion of single clipping blades is reduced, and service life of the inner clipper is prolonged.

Description

technical field [0001] The invention relates to the field of razors, in particular to inner cutters of razors. Background technique [0002] The existing rotary electric shaver includes an outer knife, an inner knife and a transmission mechanism. The outer knife is provided with a beard inlet, and the inner knife is arranged close to the inner surface of the outer knife. The transmission mechanism drives the inner knife to rotate and cooperate with the outer knife to cut the beard. During the working process, the inner knife is worn due to friction with the beard and the inner surface of the outer knife, which will affect its service life, and the inner knife of the existing rotary electric shaver, its knife arm is basically inclined, and its When shaving with the inner surface of the outer knife, the fit is not very compact, and it cannot be guaranteed that the inner knife is always parallel to the inner surface of the outer knife, which will affect the shaving effect.
