CZ2017204A3 - A chain shaving head of the razor - Google Patents

Abstract

The razor head comprises at least two sprockets (2) with a vertical axis of rotation with respect to the axis of the body (1) of which at least one is driven and which serves to guide and drive the chain, at least some of the links (4) of which are the top of the blade (5). Further, the shaving head includes a cap (9) that can have a groove (8) that guides the chain. In this cap (9) there are openings (6) through which whiskers penetrate when the clipper is used, which cut off the blades (5) on the chain links (4). In addition, a pressure washer (10) may be provided as part of the razor head, which presses the springs (7) on the underside of the chain from the underside, thereby pressing the chain with the blades (5) onto the underside of the cap (9).

Description

The shavers currently used have a shaving head either with a vibrating bar mechanism that cuts off the beard that penetrates the aperture cap or does not form a rotating disc, or discs with blades that also cover the aperture cap. There are also solutions (G ^ 19492, CN202684946U) with a belt with a blade which orbits two wheels, one of which is driven, the wheels having a horizontal axis of rotation with respect to the body of the clipper. The solution described below has the advantage over machines with a vibrating bar in the absence of vibration and a possible higher speed of the cutting edges, because there is no reciprocating movement of the bar with the blades. In machines with rotary discs under the caps, the radial arrangement of the apertures in the caps is disadvantageous, and thus has limited engagement when moving the machine in one direction during shaving, and this drawback removes the described solution. Compared to a belt with a blade orbiting a wheel with a horizontal axis of rotation, the described solution is structurally simpler, especially for the drive of the wheel that drives the belt or chain, which in the solution described below is made directly by the shaft from the motor. the solution described below is also smaller in size.

2. Summary of the Invention

The principle of the invention is that the razor head comprises at least two sprockets having a parallel axis of rotation to the axis of the body of the movement, at least one of which is driven to drive and drive a chain of which at least some of the links have cutting edges. The shaving head further comprises a cap which may have a groove which guides the chain and which bears against the edges of the chain. This cap has openings through which the beard penetrates during use, which cuts off the edges of the chain links. Furthermore, the shaving head may comprise a thrust washer which presses the springs from the underside onto the underside of the chain, thereby pressing the chain with the blades to the underside of the cover.

DETAILED DESCRIPTION OF THE INVENTION

The chain razor head shown in Figures 1 to 5 consisting of two sprockets 2 with a vertical axis of rotation relative to the axis of the body 1 of the razor mounted on the shafts 3, wherein at least one sprocket 2 is driven. The chain wheels 2 are fitted with a chain whose at least some links 4 have upwardly directed blades 5 and which cover the cover 9 with the guide groove 8 and the openings 6.

The chain is pressed against the cover 9 with the openings 6 by the washer 10 spring-loaded with the springs 7, and in the washer 10 there is an opening 11, which serves for the falling of the cut beard.
