Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reciprocating electric shaver comprising a plurality of blades connected through ribs, an inner cutter arranged in parallel and reciprocating, and an outer cutter in sliding contact with the inner cutter. Its purpose is to ensure that beard shavings, soapy water, etc. that have accumulated between the blades fall off.

The inner blade of a reciprocating electric shaver has the disadvantage that the spacing between the blades is narrow, so that beard debris and skin oils tend to accumulate between the blades, resulting in a reduction in cutting performance. In particular, when shaving with soapy water applied to the skin, the soapy water tends to accumulate between the blades and accumulate beard debris.

The present invention has been made in view of such drawbacks, and the following
The present invention will be explained according to the embodiments shown in FIGS.

In the figure, (1) is a housing, (2) is a rotating motor housed in the housing (1), (3) is an eccentric shaft attached to the output shaft of the rotating motor (2), (4) is a balancer attached to the eccentric shaft (3). (5) is a drive element that converts the rotational motion of the motor into reciprocating motion, and is supported between the thin-walled parts (5m) and (53) corresponding to the chains of the swing, and is attached to the seat part of the swing. A corresponding thick interior (5b) and an elastic member whose base is fixed to the thick interior (5b) and is elastically deformable in a direction perpendicular to the deformation direction (X in the drawing) of the thin wall portion (5 turtle) (in a direction perpendicular to the plane of the drawing). It consists of a piece (5C). The elastic piece (5C) is provided with a hole (6) into which the eccentric shaft (3) is loosely fitted with a small gap. (7) is a waterproof sheet that protects the live parts. (8) is the inner blade, which has many fan-shaped blades (8 m
), (8@)... as the center rib (8b) and the end rib (81
, (8C), and the central rib (8b) and end rib (8C) have blades (8 turtles) near each end.
They are connected by sector pieces (8d), (8d) of smaller radius. (9) is a noodle waste removing body, and the blade (81)
The blade (8m) is placed between the blades (8m long) and the vertical beams (
9m), (9m)..., horizontal bars 11 (9b) that penetrate near both ends of the vertical bars (9 turtles) and are fixed to the blades (8 tatami) by caulking to maintain the blade (81A) spacing. (
9b). The horizontal beams (9b) and (9b) are inserted through the blade (8 pins), end rib (8C), fan-shaped piece (8d), end rib (8C), and window (8C) forming a "t" shadow. The horizontal bar (9b) is caught on the lower surface of the blade (83) to prevent it from floating, and the vertical bar (91) is attached to the outer blade (described later).
11) Prevent touching. Note that the horizontal bar (9b) is prevented from falling by the fan-shaped piece (8d).

(10) is a joint that detachably connects the inner cutter (8) to the drive element (5). Reference numeral (11) denotes an outer blade having a large number of hair introduction holes and being curved in a substantially U-shape, and the blade (8) of the inner blade (8) slides into contact therewith, thereby contributing to cutting the hair. (12
) is an outer cutter frame that is close to the external force (11) and forms a beard storage chamber, which can be opened to remove beards.

In such a reciprocating electric shaver, during normal shaving and when washing the inner blade (8) by soaking it in water, the noodle waste removing body (9) moves between the blades (8). The ring (9) generates a water flow to scrape off the noodle crumbs that tend to accumulate between the blades (8) downward, and when washing the inner blade (8) by immersing it in water and moving it back and forth, the ring (9) generates a water flow that pushes the blade (8) away. 81) Scrape off the noodle crumbs in between.

FIG. 4 and FIG. 5 show a second embodiment of the present invention, in which the noodle waste removing body (9) is formed by drilling a large number of slots 71-(9C) in parallel in a U-shaped metal sheet, and between the vertical bars ( 9a) and a horizontal bar (9b) is formed at the end thereof, and a projecting end (8f) in which the fan-shaped end of the blade (8 turtle) projects outward from the end rib (8c). The inner cutter (8) shown in FIG.

This noodle waste removing body (9) has its υ-shaped frontage part cut into a blade (
When moved along the outer peripheral end surface of the blade (8a), it elastically deforms and expands, and when it passes the end of the blade (8&), it forms a slit (9C).
) has a protruding longitudinal end of the blade (8 turtles), an end (8 turtles)
f) Insert the blade (8) into the slit (9C) caught on the bottom
&) is inserted.

In this embodiment, even if the horizontal bar portion (9b) is provided integrally with the vertical bar portion (91), the inner cutter (8) k is formed using elastic deformation.
This is a preferred embodiment in that it can be attached.

FIG. 6 shows a third embodiment of the present invention in which a weight (13) is attached from below to the noodle waste removing body (9) of the second embodiment. In such an embodiment, the noodle waste removing body (9
This is a preferred embodiment in that the weight of the blade (81) is large, so that when the blade (81) reciprocates, it collides and the noodle scraps are likely to fall.

As described above, the reciprocating electric shaver of the present invention has a large number of vertical bars disposed between the blades, and a horizontal bar that connects both ends of the vertical bars to maintain the blade spacing, and that catches on the lower surface of the blades to prevent them from floating. The feature is that a noodle waste removing body consisting of a crosspiece is attached to the inner blade,
The noodle waste remover is attached to the inner blade and can reciprocate together with the inner blade, so there is no major structure or change compared to conventional reciprocating electric shavers (in some cases, it can be used in place of the conventional inner blade), and it can be used reliably. Noodle scraps can now be removed.

Claims (1)

[Claims] (11) In a reciprocating electric shaver consisting of an inner cutter that connects a large number of blades via ribs and moves in parallel and reciprocates, and an outer cutter that the inner cutter makes sliding contact with, a large number of blades are arranged between the blades. The blade is characterized in that a beard debris removing body is attached to the inner blade, which comprises a horizontal bar that connects the vertical bar and the vicinity of both ends of the vertical bar so as to maintain the spacing between the blades, and that is caught on the lower surface of the blade to prevent it from floating up.
