Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of an inner cutter that connects a large number of blades via ribs and is arranged in parallel and reciprocates in the direction in which the blades are parallel; an outer cutter that the inner cutter slides into; and a motor. This relates to a reciprocating electric shaver consisting of a driver that converts rotational motion into reciprocating motion, and its purpose is to reliably remove accumulated matte, soapy water, etc. between the blades.

Since the inner blades of reciprocating electric shavers have narrow blade spacing, it is easy for matte and skin oils to accumulate between the blades (
There was a drawback that a decrease in cutting performance was a problem. In particular, when shaving with soapy water applied to the skin, the soapy water tends to accumulate between the blades and cause matting.

The present invention was devised in view of these drawbacks, and the following are the first points.
The present invention will be explained according to the embodiment shown in FIGS.

In the figure, (1) is a housing, (2) is housed in the housing (1), and the output shaft (2m) and (2'b) are located above and below.
), (3) is an eccentric shaft attached to the upper output shaft (2) of the rotary motor (2), and (4) is a balancer attached to the eccentric shaft (3). (5)
is a driver that converts motor rotational motion into reciprocating motion,
Thin parts (51), (51) corresponding to the chains of the swing, supported between the thin parts (531) and a thick inner part (5b) corresponding to the seat part number of the swing, and the thick part 11 (5b). Deformation direction of the thin walled portion (51) whose root is fixed (X shown)
It consists of an elastic piece part (5C) that can be elastically deformed in a direction perpendicular to (perpendicular to the plane of the drawing). And elastic piece part (5c)
A hole (6) is provided in which the eccentric shaft (3) is loosely fitted with a small gap. (7) is a waterproof sheet that protects the live parts. (8) is an inner cutter, and a large number of fan-shaped blades (811), (8+1), . . . are connected through ribs (8b) and arranged in parallel.

(9) is a joint that detachably connects the inner cutter (8) to the drive element (5). Reference numeral 10 denotes an outer blade having a large number of hair introduction holes and being curved into a substantially U-shape, and the blade (81) of the inner blade 2 slides into contact with the blade to contribute to cutting the hair.

Reference numeral (11) is an outer cutter frame that is close to the outer cutter (10) and forms a beard storage chamber, which is opened to allow removal of beards. (
12) is the lower output shaft (2b) of the rotary motor (1)
It is the first bevel gear attached to the rotating motor (1).
A lower output shaft is attached to a shaft (15) that meshes with a second bevel gear (14) that is rotatably supported by a bearing plate (13) attached to the lower surface of the shaft and that passes through the second bevel gear (14). (2b
) transmits a rotational force in the orthogonal direction. (16), (1
Reference numeral 6) denotes eccentric weights attached to both ends of the shaft (15), which rotate to forcibly vibrate the housing (1).

This vibration is transmitted from the housing (1) to the inner cutter (8), causing the blade (8 gourds) to vibrate in the illustrated Y direction, that is, in a direction substantially perpendicular to the parallel direction of the blades. Further, the shaft (15) is provided with a ring-shaped protrusion (17), which is engaged with the switching handle (18).
is moved in the left-right direction in Figure 3, and the second bevel gear (14)
can be freely meshed with the first bevel gear (12), and forced vibration force is applied only when removing noodle scraps, but such a configuration is a preferred embodiment of the present invention.

In the figure, (19) is a storage battery, (2o) is a charging connection pin, (21) is a printed board, and (22) is a power switch handle.

With such a reciprocating electric shaver, normal shaving can be performed as before, and by vibrating the inner blade in a direction substantially perpendicular to the direction of reciprocation, the matte that has accumulated between the blades can be removed. Also, if the inner blade is immersed in water and vibrated, the removal of matte will be particularly promoted.

In the reciprocating electric shaver of the present invention, an eccentric weight is attached to the motor's output rotating shaft to forcibly vibrate the razor housing, and the vibrations are transmitted to the inner blades to move the blades in a direction approximately perpendicular to the parallel direction of the blades. Since it is characterized by being configured to vibrate, it has become possible to reliably remove matte stuck between the blades.

Claims (1)

[Claims] (1) An inner blade that connects a large number of blades via ribs and is arranged in parallel and reciprocates in the blade parallel direction, an outer blade that the inner blade slides into contact with, and converts the rotational motion of the motor into reciprocating motion. In a reciprocating electric shaver consisting of a driver, an eccentric weight is attached to the output shaft of the motor to forcibly vibrate the razor/Using, and the vibration is transmitted to the inner blade, causing the blade to vibrate in a direction approximately perpendicular to the parallel direction of the blades. A reciprocating electric shaver characterized in that it is configured to force the user to move.
