SU755554A1 - Electric shaver cutting head - Google Patents

Description

The invention relates to household appliances and relates to an electric razor.

The famous cutting head of an electric razor with a rotating movement of movable knives and a net cutting head consisting of a fixed net knife of a cylindrical shape, is gently curved around the trellis holder, inside of which there are rotating movable knives. Movable knives are a set of plates, the cutting edges of which in the process of rotation make cutting the hair that falls into the holes of the fixed mesh knife [1].

The disadvantage of the famous razor is that its cutting head does not provide high-quality shaving in hard-to-reach places and shaving relatively high hair, the size of more than one-day growth.

Closest to the invention to the technical essence and the achieved result is the cutting head of the electric shaver, which contains an external mesh knife mounted in the housing and an internal cylindrical drive knife connected to the drive knife of the end cutting unit.

2

The ends of the mesh knife are shearing elements [2].

The disadvantage of this head is that the movable knife of the block is made on the end of a cylindrical knife, i.e. rigidly soy _{5 is} dinen with it, while the cutting block is intended only for cutting and trimming high hair and is not suitable

for shaving

The purpose of the invention is to improve the quality of shaving inaccessible skin.

10 The above object is achieved in that the drive shaft of the mechanical cutting blade unit is located at an angle to the shaft of the cylindrical knife, wherein the shafts are interconnected by a spring-loaded leash socket cutting unit has a ^circuit-ώ ents, wherein the end cutting block

made of disc type.

FIG. 1 shows an electric shaver,

lengthwise cut; in fig. 2 - the same, front view.

20 The shaver consists of an electric motor 1, connected through a gearbox 2 to a shaft 3 of an internal cylindrical driving knife 4, in contact with an external mesh knife 5. Shaft 3 is connected by an intermediary3

four

The spring loaded leash 6 with the power knife 7 of the face cutting unit 8, wherein the shaft of the power knife of the face cutting unit is angled to the shaft of the cylindrical knife. The stationary knife 9 dish-shaped type mechanical cutting unit 8 is installed in the cage 10 of the head 11 of the electric razor. The face cutting unit has a switch 12. The shaver head 11 with the mechanisms installed on it is placed in the housing 13 and covered with a casing 14.

Shaver works as follows.

The rotation of the motor 1 through the gearbox 2 is transmitted to the shaft 3 of the drive knife 4, in contact with the mesh knife 5. In turn, the shaft 3 through the lead 6 transmits the rotation of the drive knife 7 of the face cutting unit 8, which is turned on and off as needed via a switch 12.

The implementation of the proposed electric shaver with two cutting units allows for high-quality shaving in hard-to-reach parts of the face (in some parts of the neck, near the ears and under the nose), as well as high-hair shaving.

The presence of the switch of the face cutting unit allows to significantly reduce the overall noise level of the electric razor when shaving, reduce the wear of the cutting elements of this unit and provide additional 6

comfort when using an electric razor.

The use of the shaft of the drive knife of the mesh knife block as a drive for the end block allows the design of the shaver to be significantly simplified.
