Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an inner blade of a reciprocating electric shaver.

[Background technology]

Shaving with an electric razor generally shaves off skin fat together with beard shavings, and there is a problem in that the highly adhesive skin fat accumulates on the sides of the inner blade, particularly on the tip edge of the inner blade.
Therefore, there was a drawback that the deposits were difficult to remove even after cleaning with water.

[Purpose of the invention]

An object of the present invention is to provide an inner cutter body of a reciprocating electric shaver that allows deposits on the inner cutter blade to be easily removed by washing with water.

[Disclosure of the invention]

The inner cutter body of the reciprocating electric shaver of the present invention includes an inner cutter base that reciprocates, and an inner cutter base that is arranged side by side in the reciprocating direction of the inner cutter base and viewed from an end of the inner cutter base in the reciprocating direction. The device includes a plurality of inner blades each having a hollow portion formed therein, and a turbulence generating member disposed between the inner blades and within the hollow portion when viewed from the end in the reciprocating direction.

According to the configuration of the present invention, since the turbulence generating member is provided between the inner blades having hollow portions, the turbulent flow during washing can quickly and reliably remove the deposits on the inner blades.

A first embodiment of the invention is shown in FIGS. 1 to 4. That is, the inner cutter body 4 of this reciprocating electric shaver mainly includes inner cutter bases 6a to 6d that reciprocate, and inner cutter bases 6a to 6d that are arranged side by side in the reciprocating direction of the inner cutter bases 6a to 6d, as shown in FIG. At the same time, the inner cutter base 6
Hollow part 7a viewed from the end in the reciprocating direction of a to 6d
A turbulence generating member 8 is provided between the inner blades 7 and within the hollow portion 7a when viewed from the end in the reciprocating direction.

A reciprocating electric shaver to which this inner cutter body 4 is applied has a motor and a reciprocating conversion mechanism built into the case 2, an outer cutter frame 3 is attached to the protruding portion of the drive rod 1, and a net is attached to the outer cutter frame 3. A shaped outer cutter 3a is attached, and an inner cutter body 4 is attached to the drive rod 1, and the inner cutter blades 7 are in contact with the inner surface of the outer cutter 3a. The inner cutter body 4 is connected to the drive rod 1 via a joint stand 5, and the three inner cutter bases 6a to 6c are connected to the joint stand 5.
and is connected by reinforcing members 9 at both ends. Also, the inner blade 7
. . . has a semicircular shape, and both end portions and the center portion are embedded in the inner cutter bases 6a to 6c by simultaneous molding. Further, a turbulence generating member 8 is installed on the inner cutter bases 6a, 6c between each inner cutter blade 7, and this member 8 is an arcuate ring-shaped thin plate having a smaller diameter and arc length than the inner cutter blade 7. Only both ends are supported by inner cutter bases 6a and 6c at both ends. The hollow portion 8a of this turbulence generating member 8 and the hollow portion 7a of the inner cutter blade 7 are communicated with each other in the longitudinal direction of the bases 6a to 6c.

In a reciprocating electric shaver, when the drive rod 1 reciprocates due to the operation of the motor, the inner blade body 4 makes the same movement, and the cutting edge of the inner blade 7 reciprocates with the cutting edge in elastic contact with the inner surface of the outer cutter 3a. The hair introduced through the blade hole of the blade 3a is cut. Also, washing with water is case 2.
This is done by immersing the outer cutter 3a in water with the outer cutter 3a facing down and operating the motor to drive the inner cutter 4. At this time, outer blade 3
Conventionally, the path through which water flows inside a is almost laminar due to the reciprocating movement of the inner blade 4, but the turbulence generating member 8 is an extremely thin plate that reduces water resistance. As a result, the water oscillates as shown by arrow P in FIG. 3, and the flow of water changes as shown by arrow Q, creating turbulent flow. As a result, highly adhesive skin fat and beard debris can be removed more easily than before due to the turbulence effect.

A second embodiment of the invention is shown in FIGS. 5-8. That is, in the inner cutter body 4 of this reciprocating electric shaver, the turbulence generating member 10... has a protrusion as an example, and the inner cutter body 4 has a protrusion between the inner cutter blades 7... so as to face the hollow portion 7a. Provided integrally with the reinforcing member 9 of the blade bases 6a to 6c or the inner blade bases 6a to 6c,
Furthermore, as shown in FIGS. 6 and 7, the inner cutter base 6a
The turbulence generating members 10 arranged in the reciprocating direction of ~6d are shifted from each other in the lateral direction of the inner cutter bases 6a~6c, and the number thereof is also different.

With this configuration, the inner blade body 4 is removed when washing with water.
The protrusion 10 vibrates back and forth as shown by the arrow.
This becomes an obstacle to the water flow and causes turbulent flow Q', which has the same effect as the first embodiment.

A third embodiment of this invention is shown in FIGS. 9 and 10.
As shown in the figure. That is, the inner cutter body 4 of the reciprocating electric shaver has a tongue piece 11 protruding from the edge toward the hollow part 7'a side of the inner cutter blade 7', and inner cutter bases 6a to 6.
A plurality of protruding turbulence generating members 12 are formed between the inner blades 7' of c, facing the hollow portion 7'a, and some of the turbulence generating members 12a are opposed to the tongue piece 11. That's what I do. Note that 13 is a push-up spring, 14 is an outer cutter frame attachment projection, 15 is a motor, 16 is an eccentric shaft, and 17 is a reciprocating transducer.

In the operation of the inner cutter body 4 of this reciprocating electric shaver, since the inner cutter blade 7' is a thin plate, it deforms greatly due to the reciprocating motion of the inner cutter body 4 under a constant load. 11, the amount of deformation of the blade 7' can be kept approximately constant, and the thinner blade 7' produces a pleasant shaving sound and enhances the image of shaving. Moreover, with this configuration, the width N (FIG. 10) of the inner cutter blade 7' can be made even thinner, for example, N=0.3.
~0.8mm, and the blade thickness can be made thinner in some areas to increase the comfortable shaving sound. Other effects are the same as those of the first embodiment.

Furthermore, since the outer cutter frame 3 and the inner cutter body 4 of this reciprocating electric shaver can be removed from the case 2, they can also be disassembled and washed with water.

〔Effect of the invention〕

According to the inner cutter body of the reciprocating electric shaver of the present invention, since the turbulence generating member is provided between the inner cutter blades having a hollow portion, the turbulent flow during washing quickly and reliably removes deposits on the inner cutter blades. There is an effect that it can be done.
