Abstract

The utility model relates to a rotation-type electric shaver tool bit component, which comprises an inner movable cutter component and an outer static cutter component, wherein the inner movable cutter component comprises a driving shaft, a rotation disc and a plurality of uni-wafer movable cutting tips, wherein a plurality of movable cutting tip seats with the quantity being consistent with that of the uni-wafer movable cutting tips is uniformly arranged on the rotation disc, and the rotation disc is also provided with a round sheet, and the round sheet is arranged below the movable cutting tip seats, and a plurality of spring strips with the quantity being consistent with that of the uni-wafer movable cutting tips is uniformly arranged on the round sheet, and the uni-wafer movable cutting tips can be movably plugged on the movable cutting tip seats in the vertical direction, and the lower part of the cutting tips can be contacted with the spring strips, and a spring is arranged between the driving shaft and the rotation disc, and the spring is arranged on the driving shaft and is contacted with the bottom part of the rotation disc, and the outer static cutter is a net foil which is made of a metal sheet. With the structure, the rotating shaft can make elastic relative motion corresponding to the driving shaft; moreover, the spring strips on the rotation disc can control each uni-wafer movable cutting tip to make up-down elastic motion; and because being applied to the face area with complicated curved surface, the outer static cutter and the arrived uni-wafer movable cutting tips can vary along with the fluctuation of the face, thereby having a good shaving effect.

Description

Rotary electric shaver cutter head assembly

Technical field

The utility model relates to a kind of rotary electric shaver, relates in particular to the wherein improvement of cutter head assembly structure.

Background technology

Rotary electric shaver cutter head assembly comprises circumscribed quiet knife assembly and inscribe moving knife assembly, and it is several cutting blade to distribute on the inscribe moving knife assembly, can driven inscribe moving knife and circumscribed quiet cutter be fulcrum with the center of circle, make the rotation cutting movement around fulcrum.Because distribute on each circumscribed quiet cutter and the inscribe moving knife several the cutting blade that every handle is distributed on the inscribe moving knife can not effectively excise the beard that enters circumscribed quiet cutter uneven stressed property between the cutting blade, the effect that directly causes shaving descends.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of rotary electric shaver cutter head assembly, to improve the effect that shaves of existing rotary electric shaver.

For solving the problems of the technologies described above, rotary electric shaver cutter head assembly provided by the utility model, comprise inscribe moving knife assembly and circumscribed quiet knife assembly, described inscribe moving knife assembly comprises driving shaft, rolling disc and some the one chip cutting blade, evenly be provided with the moving knife bar consistent on the rolling disc with one chip cutting blade quantity, described rolling disc also is provided with a thin rounded flakes and described thin rounded flakes is positioned at moving knife bar below, be evenly distributed with on the described thin rounded flakes and the consistent spring leaf of one chip cutting blade quantity, described one chip cutting blade vertical direction can be interted on the moving knife bar up and downly and its underpart contacts with corresponding spring leaf, be provided with spring between driving shaft and the rolling disc, spring places on the driving shaft and with the rolling disc bottom and contacts.

Described circumscribed quiet cutter is the net paper tinsel of being made by sheet metal.

The beneficial effects of the utility model are: adopt the rotary electric shaver cutter head assembly of said structure can make the relative motion of elasticity between rolling disc and the driving shaft, and the spring leaf on the rolling disc, can control every elastic movement about the one chip cutting blade work, make every the one chip cutting blade elastic pressure its pressure to circumscribed quiet cutter is provided and circumscribed quiet cutter to be the net paper tinsel made has bigger crooked deformability, when being used to complex-curved facial zone is arranged, this circumscribed quiet cutter and the one chip cutting blade that is arrived can provide the good effect that shaves thereupon floating variation.

Below in conjunction with drawings and Examples technology contents of the present utility model is described further.
