Therefore, the annular recess 20 of the outer cutter base 18 is formed below the inner cutter assembly 35 with respect to the outer cutter 29, and functions as a whisker storage space (see FIG. 1).

As shown in FIG. 4, the cap 12 has an annular peripheral wall 42 having a lower stepped surface 41 on one end side and a circular plate 43 for closing the other end side of the annular peripheral wall 42. It is formed of a transparent bottomed cylindrical body formed to have a larger diameter than the outer diameter of the outer cutter base 18.

At the diametrical position of the annular peripheral wall 42, at the time of cleaning, two rectangular openings, an upper cap opening 44 located at the top and a lower cap opening 45 located at the bottom, and upper and lower cap openings. Two locking projections 46, which are arranged in parallel with each other (downward in the drawing) on the stepped surface portion 41 and project from the annular peripheral wall 42, are formed.
A box-shaped water level confirmation part 49 having a cap communication port 47 (detergent injection port) formed on the peripheral edge of the circular plate 43 on the lower cap opening 45 side and having an opening 48 only on the upper cap opening 44 side is formed. Has been done. The water level confirmation unit 49 can confirm the amount of the liquid detergent S during injection and during washing.

Further, the cap 12 has a stepped surface portion 41 sandwiched from the lower end side in a fitted state, and when the cap 12 is mounted on the main body case 11, a cap seal packing for ensuring airtightness between the cap 12 and the razor portion 14. 50 and a cap opening / closing ring 52 that slides in close contact with the outer periphery of the annular peripheral wall 42 with a rectangular cap opening O-ring 51 attached to the upper and lower cap openings 44 and 45 interposed. (See Figure 4).

The cap seal packing 50 has an opening 5 through which both the locking projections 46 project when the step seal 41 is fitted.
3 and an annular groove 54 into which the step surface portion 41 is inserted, and a water leakage prevention wall 55 that is in close contact with the outer surface 14a of the razor portion 14. The outer peripheral surface of the cap seal packing 50 has an annular peripheral wall 42 when fitted to the step surface portion 41.
And become flush.

The cap opening / closing ring 52 is an annular peripheral wall 42.
Has a size to cover the upper and lower cap openings 4
It has a total of three ring openings, that is, two ring openings 56 corresponding to 4, 45 and one ring opening 56 located in the middle of these two ring openings 56.

At the inner lower end portion of the cap opening / closing ring 52, two groove portions 5 into which the both locking protrusions 46 are fitted, respectively.
7, when the cap opening / closing ring 52 slides on the annular peripheral wall 42, only the upper cap opening 44 has the ring opening 56.
And the upper and lower cap opening 4
Both 4, 45 communicate with the ring opening 56 and are formed at such positions that they are simultaneously opened.

For this reason, by rotating the cap opening / closing ring 52, the upper cap opening 44 is formed, if necessary.
It is possible to switch between a state in which only the top is opened (see FIGS. 6A and 6B) and a state in which the upper and lower cap openings 44 and 45 are simultaneously opened (see FIG. 6C).

Then, as shown in FIG.
Is attached to the razor portion 14 of the main body case 11 in a state of covering the outer blade 29, thereby including the outer blade base opening 21 and forming a gap D outside the outer blade 29. The closed space that forms the detergent circulation path R that passes through the gap D and the annular recess 20 (beard collecting space) via the blade base opening 21 and the outer blade 29 is the outer edge of the outer blade 29 that is the outer periphery of the opening of the razor portion 14. Formed around. (See FIG. 1) Next, the operation of the electric shaver having the above configuration will be described.

First, hold the handle portion 13 of the electric razor 10 in the hand, attach the cap 12 to the razor portion 14 to form a detergent circulation path R with the main body case 11, and rotate the cap opening / closing ring 52. Upper cap opening 4
Only 4 is opened.

In this state, as shown in FIG. 6 (a), the grip portion 13 is directed upward, the razor portion 14 is positioned downward, and the liquid detergent S is injected from the opening 48, whereby the cap communicating port 47 is formed. The detergent circulation path R is filled with the liquid detergent S via.

An appropriate amount of the liquid detergent S to be used can be easily confirmed by the water level confirmation section 49.

Then, the inner blade 37 is rotated. Inner blade 37
When the liquid detergent S in the detergent circulation path R is agitated by the rotation of, the liquid detergent S escapes from the outer surface of the outer blade 29 in the gap D to the back surface of the outer blade 29, passes through the annular recess 20, and further the outer blade opening portion. 21 circulates to the outer surface side of the outer blade 29 of the gap D through the outer side of the outer cutter base 18 of the gap D. At this time, the bubble B generated recirculates between the gap D and the annular recess 20. The whiskers and the like stuck to the annular recess 20 and the inner blade 37 can be washed away (see FIG. 1).

That is, the rotation of the inner blade assembly 35 causes the inclined portion 38 formed on the inner blade base 36 and the inclination of the blade edges of the inner blade 37 to act, so that the liquid detergent S and the air injected into the gap D are caused. Together, they will pass through the innumerable small holes 30 of the outer blade 29 and be drawn to the back surface side of the outer blade 29, and when they pass through the innumerable small holes 30, they will be expanded and the volume will increase. The inner blade 29 and the inner recess of the annular recess 20 can be completely filled. In addition, the bubbles B repeatedly pass through the fine holes 30 of the outer blade 29, and become finer particles with the lapse of time, so that the cleaning power is increased.

Then, as shown in FIG. 6 (b), the bubbles B generated in excess of the volume of the closed space formed inside the cap 12 go out of the cap 12 through the upper cap opening 44 together with the whiskers. The liquid detergent S is reduced in accordance with the discharge. The degree of decrease of the liquid detergent S can be confirmed by the water level confirmation unit 49. The bubbles B are continuously generated during the rotation of the inner blade 37 until the liquid detergent S runs out.

After the generation of the air bubbles B is stopped and the cleaning is completed, as shown in FIG.
Is rotated to open both the upper and lower cap openings 44 and 45, and tap water W, for example, is poured from the upper cap opening 44 to wash away the remaining bubbles B.

By the way, during washing and when washing away the bubbles B, the cap seal packing 50 and the cap opening O-ring 51 or the shaft seal packing 33.
The outer detergent O-ring 23 prevents the liquid detergent S from leaking from the cap 12, and the liquid detergent S does not penetrate into the motor 16 and the razor portion 14.

As described above, even a beard that has sticked to the inner blade 37 or the outer blade 29 due to the fat content of the skin surface contained in the shaved beard is peeled off by the bubbles B of the liquid detergent S. It is possible to wash it away and wash it thoroughly. Also, by injecting the liquid detergent S and forming bubbles B,
In addition to the fact that the detergent can be easily injected, the inner blade 37 and the annular recess 20 can be evenly and appropriately filled, and further, it is possible to easily wash with water after washing.
The bubbles B can be easily discharged.

The cap 12 of the above embodiment may also be used as a stand.

The holder / cap 60 shown in FIG. 7 is a box having a storage portion 61 for holding the razor portion 14 in a fixed manner and for holding the electric razor 10 in the same posture as during cleaning shown in the above embodiment. It is formed by the body.

The upper opening 62 of the accommodating portion 61 has a handle portion 13
Is covered by an opening / closing lid 65 that is openably / closably held by a shaft support 64. The opening / closing lid 65 has a tubular portion 66 having the same function as the upper cap opening 44. Are formed. 67 is a razor section 14
Is a locking protrusion for fixing and holding.

When using the pedestal / cap 60, the pedestal / cap 60 is placed on a table, for example, and the opening / closing lid 65 is opened to fill the storage section 61 with the liquid detergent S and then the opening / closing lid 65 is closed. Other than that, the same cleaning effect can be obtained by the same operation as the cap 12.

In particular, in the case of cleaning with the cap 12, the electric razor 10 must be held by hand during cleaning, but in the case of the cradle and cap 60, this is not necessary.

Further, the cap 12 of the above embodiment may be of the liquid detergent S injection type at any time.

The cap 70 shown in FIG.
Instead of 9, a bottom surface 71 is formed in the center of the outer surface to form a concave injection port 72 in which the outer blade 29 abuts, and the bottom surface 71 is formed in a mesh shape to form a mesh opening 73 corresponding to the cap communication port 47. The cap 12 has the same structure as that of the cap 12 except that the cap is formed.

When using the cap 70, as shown in FIG.
As shown in FIG. 1, the inner blade 37 is dropped while the liquid detergent S is dropped from the detergent container A directly into the inlet 72 with the surface of the inner blade 37 facing upward.
By rotating (see (a)) and stopping the dropping of the liquid detergent S (see (b)) when the air bubbles B overflow from the inlet 72 (see (b)). It is possible to inject a small amount of the liquid detergent S while checking the generation state of the bubbles B without injecting it into the inside, and it is possible to reliably use an appropriate amount of the liquid detergent S. Then, after washing, it is washed off with tap water W or the like (see (c)).

Other functions and effects are similar to those of the cap 12.
