Description

Rotary shaver head and cutter mesh thereof

[ technical field ] A method for producing a semiconductor device

The utility model relates to a rotatory razor tool bit, the utility model discloses still relate to a sword net of rotatory razor tool bit.

[ background of the invention ]

The rotary shaver is not easy to hurt skin and cause bleeding, and is characterized in that a cutter mesh is used as a protective cover, hair inlet grooves or pores with small width are formed in the cutter mesh, and the hair inlet grooves or the pores can be generally used for allowing hairs to enter and can prevent the skin from being squeezed into the cutter mesh to be prevented from being cut by a rotating movable cutter. Like the technical solution disclosed in the utility model with publication number CN2892408Y, the present rotary shaver in the market generally comprises a body and a head, and the head comprises a bracket and a shaver set, wherein the shaver set comprises a knife net (i.e. an outer cutter) and a movable knife (i.e. an inner cutter) which can be driven to rotate, and the knife net is installed on the inner side of the bracket, only the upper end of the knife net is exposed on the bracket, when shaving, the upper end surfaces of the bracket and the knife net move along with the skin, and hairs enter the knife net from hair inlet grooves or hair inlet holes to be cut.

At present, the existing rotary shaver has the following defects:

1. because the width of the hair inlet groove is smaller, short beards can enter easily, but long beards can be pressed down and inclined easily when the hair-cutting net moves along the skin, only a small part of long beards can enter when the hair-cutting net happens to be opposite to the hair inlet groove, most of long beards are difficult to enter the hair-cutting net from the hair inlet groove, and the long beards need to move repeatedly for many times to promote the beards which do not enter the hair-cutting net to enter the hair inlet groove to be cut, so that the shaving efficiency is lower.

2. Because the top of the knife net is usually flush with or slightly protruded from the top of the bracket, and the knife net is usually arranged on the bracket in a way of floating up and down through the elastic sheets, when the knife net moves along the skin, the knife net is usually compressed by the skin, so that the top surfaces of the bracket and the knife net move along the skin; regardless of the direction of movement, the bracket is positioned at the front side of the knife net, and the knife net presses the hairs one by one, thereby further increasing the difficulty that the long beard enters the knife net through the hair inlet groove.

The present invention has been made in view of this object.
