Problems solved by technology

[0002] The blades of the existing rotary double-ring shaving heads are mostly formed by bottom-up multi-channel bending. It is difficult to guarantee the coaxiality accuracy of multiple knives distributed on the same ring structure on the blade, which easily leads to the discrepancy between the blade and the knife net. Poor fit, the sharpness and sound quality of the razor are not good, and the cutting edge is also easy to wear, which reduces the service life of the shaving head
However, the existing blade structure is obtained by bending downwards and upwards in multiple ways, which consumes more raw materials, lower material utilization rate, and serious material waste, which is not conducive to energy saving and environmental protection, and the existing The blade cutter is a single-ply cutter that leaves residue after shaving
[0003] In addition, the inner ring knife net and the outer ring knife net of the existing rotary double-ring shaver are usually composed of rectangular beard inlet holes. Due to the single structure of the inner ring knife net and the outer ring knife net, the beard will enter the knife net Slow, single entry angle, affecting the speed of beard entry, resulting in low shaving efficiency

Embodiment Construction

[0026] The present invention will be further explained below in conjunction with specific embodiments.

[0027] Such as Figure 1-2 A rotary electric razor blade shown as shown includes a main blade base 1. Two sets of coaxial inner ring cutters 2 and outer ring cutters 5 are arranged on the main blade base 1. The main blade base An auxiliary blade is arranged at the bottom of 1 and an elastic auxiliary cutter 4 is arranged on the periphery of the auxiliary blade; the auxiliary cutter 4 is arranged at the front end of the working part when the outer ring cutter 5 rotates, and the auxiliary cutter 4 forms an angle with the outer ring cutter 5 of the main blade. The lower part of the auxiliary cutter 4 is integrally connected with the negative film 3, the negative film 3 is arranged obliquely downward, and the auxiliary cutter 4 is arranged obliquely relative to the outer ring cutter 5. The outer ring cutter 5 and the main blade base 1 are connected by a bending arm 6, a bayonet is...

Abstract

The invention relates to a shaving head device of a rotary type electric shaver. The shaving head device comprises a shaving head blade and a blade net, and is characterized in that the shaving head blade comprises inner circle knives and outer circle knives, the inner circle knives and the outer circle knives are concentrically arranged on a main blade base, auxiliary blades are arranged at the bottom of the main blade base, and elastic auxiliary knives are arranged on the peripheries of the auxiliary blades; the auxiliary knives are arranged at the front ends of the working portions of the outer circle knives of a main blade when the outer circle knives rotate, included angles are formed between the auxiliary knives and the outer circle knives of the main blade, and the auxiliary knives rebound after being in contact with beards to be then in contact with the outer circle knives to be lifted upwards. According to the structure of the shaving head device, the strength of a base body can be effectively improved through the inner circle knives, it is guaranteed that the coincidence of running tracks of the knives in working is high, the service life of the knives is prolonged, the matching degree of the blade and the blade net is improved, the sharpness is high, and the sound coincidence is high. The beards can conveniently enter the blade net at multiple angles through the design of the M-shaped blade net, and the shaving efficiency is improved.

Description

Technical field [0001] The invention relates to a shaving head device of a rotary electric shaver. Background technique [0002] The blades of the existing rotary double-ring shaving heads are mostly formed by bottom-up multi-track bending. The coaxiality accuracy of the multiple cutters distributed on the same ring structure on the blades is difficult to ensure, which easily causes the blade and the knife net. Poor coordination makes the sharpness and sound quality of the shaver poor, and the cutting edge of the cutter is also easier to wear, which reduces the service life of the shaving head. However, because the existing blade structure is formed by bending the tool downward and upward in multiple passes, it needs more raw materials, the utilization rate of materials is low, and the material waste is serious, which is not conducive to energy saving and environmental protection. The blade cutter is a single-layer cutter, and there will be residues after shaving. [0003] In add...
