Description

  The present invention relates to an electric razor that can automatically apply oil to an outer blade by attaching a cap to the head of the electric razor, and a cap for the electric razor.

The electric razor is a tool that has a small hole group, and the inner blade provided inside the outer blade slides or reciprocates or rotates in contact with the outer blade so that the rod fitted into the hole of the outer blade is inserted. Since it is a mowing type, application of oil is recommended to reduce friction on the sliding surface and extend the life of the cutting edge.
This is a cloth impregnated with oil and requires only a simple operation of wiping the outer surface of the outer blade. The oil flows from the hole group of the outer blade to the sliding contact surface with the inner blade.
However, it is easy to forget to perform the above oil application work regularly, and there is no time for the application work before going to work in the morning, and it is troublesome to apply oil to the outer blade. It becomes. Some users are ignorant about the need to apply oil to the outer blade.

The present invention solves the problem of forgetting to apply oil to the outer blade of an electric razor, lack of time for oil application, or troublesomeness of oil application.
After using an electric razor, pay attention to the fact that it is normal practice to put a cap on the head including the outer blade to protect the outer blade. The technical problem was that it could be applied.
As a result of investigating known examples, it was not possible to find literature on automatic supply of oil to the outer blade or inner blade of an electric razor.

The cap for an electric razor according to claim 1 comprises a cap body (5) in a cap (4) detachably covering a head portion (3) having an outer blade (32) and an inner blade (33) of the electric razor. And a flexible member (6) such as a non-woven fabric that is attached to the main body and impregnated with oil. When the cap (4) covers the head portion (3), the flexible member (6) is an outer blade ( in contact with the 32),
The cap body (5) is formed with a flexible member accommodating chamber (8). The flexible member accommodated in the accommodating chamber (8) is detachably accommodated on the outer blade side bottom surface of the flexible member accommodating chamber (8). There is a hole (81) for contact between (6) and outer blade (32),
The flexible member housing chamber (8) is provided with a lid (7) that is recessed on the outer blade side and opens on the opposite side, and is opened and closed by a hinge (71). The lid (7) includes the lid (7). A convex part (74) is formed which presses the flexible member (6) and forcibly protrudes from the hole (81) of the storage chamber (8) when the body is closed .

Claim 2 is the cap for an electric shaver according to claim 1 , wherein the lid (7) impregnates the flexible member (6) by pressing the outer periphery of the flexible member (6) when the lid is closed. It has a ridge (75) which prevents the oozed oil from seeping out.

According to a third aspect of the present invention, the cap (4) according to the first or second aspect is detachably placed on the head portion (3) including the outer blade (32) and the outer blade (32).

When the cap (4) is placed on the head (3) of the electric razor, the flexible member (6) impregnated with oil hits the outer blade (32) and the oil is automatically applied. In particular, it can be applied to the outer cutters (32) and (32).
It is easy to put the cap (4) on the head part (3) of the electric shaver after use even during busy hours before going to work or before going to school, and most people should be doing so. Therefore, the oil application to the outer blade (32) can be realized without performing the operation of applying the oil to the outer blade (32).
The oil applied to the outer blades (32) and (32) goes around the sliding contact surface with the inner blades (33) and (33), reduces friction on the sliding contact surface, and extends the life of the cutting blade. In addition, noise due to friction can be reduced.

Further , since the flexible member (6) is removably accommodated in the flexible member accommodating chamber (8) of the cap (4), if the flexible member (6) becomes dirty, it is removed from the flexible member accommodating chamber (8) and cleaned. It is convenient to wash or replace.

Further, when the lid (7) is closed, the convex portion (74) on the lid (7) presses the flexible member (6) and is flexible from the hole (81) at the bottom of the flexible member accommodating chamber (8). Since a part of the member (6) protrudes and is forcedly pressed against the outer blade (32), oil is reliably applied to the outer blade (32).
Further, when the flexible member (6) is pressed against the outer blade (32), the oil oozes out from the flexible member (6), so that the oil can be more smoothly applied to the outer blades (32) and (32). Done effectively.

Electric shaver dexterity cap of claim 2, prevents by pressing the outer peripheral portion of the flexible member (6) when closing the lid (7), the oil impregnated into the flexible member comes penetrates to the outside of the flexible member Therefore, it is possible to prevent oil from leaking to the outside of the flexible member housing chamber (8) and contaminating the periphery of the electric razor.

The movement shafts (37) and (37) for reciprocally moving the shaft in the lateral direction protrude, and the movement shafts (37) and (37) are connected to the motor (15) via a reciprocating drive mechanism (35). .

The head portion (3) is detachably attached to the upper end of the handle portion (1) and has a substantially rectangular peripheral wall-like head portion case (31) having an upper surface and a lower surface opened, and the head portion case (31). The two outer blades (32) and (32) that protrude from the upper surface opening of the case and are detachably disposed on the case (31), and the shave blade (34) and the slit blade when sandwiching the outer blades (32) and (32) (38) and an inner blade (33) that is detachably attached to the moving shafts (37) and (37) and slides in sliding contact with the outer blades (32) and (32) inside the outer blades (32) and (32). (33) and a cutting blade (34) and a blade inside each of the slit blades.
Both the outer blades (32) and (32) and the inner blades (33) and (33) are obtained by bending a thin metal plate having a large number of holes into an inverted U shape and supporting it on a holder.
Projections (36) and (36) having a low height for softly locking a cap (4) to be described later are formed on the front and back of the head case (31).

As shown in FIGS. 4 to 10, the cap (4) is detachably covered on the top of the head case (31) so as to cover the outer blades (32) and (32) and the sharpening blade (34). It comprises a cap body (5) and a flexible member (6) attached to the cap body and impregnated with oil.
The flexible member (6) of the embodiment is a non-woven fabric (60) having a thickness of about 1 mm, and covers the shaving blade (34) and the slit blade (38) when sandwiching the outer blades (32) and (32). Is formed.
In the central portion of the nonwoven fabric (60), positioning holes (61) (61) are formed on both ends in the longitudinal direction.

The ceiling portion of the cap body (5) is formed with a substantially rectangular flexible member accommodation chamber (8) that is shallowly recessed on the outer blade side and extends in a direction along the outer blade (32). One or more holes (not shown) in which the nonwoven fabric (60) accommodated in the accommodation chamber (8) can partially protrude to the outer blades (32) (32) side on the bottom surface of the flexible member accommodation chamber (8). 81) (81) has been established. The number of holes (81) in the embodiment is two, and is a long hole that is long in the direction along the outer blades (32) and (32).
Short protrusions (82) and (82) are formed on the bottom of the flexible member housing chamber (8) to fit in the holes (61) and (61) of the nonwoven fabric (60) and prevent the nonwoven fabric (60) from being displaced. ing.

At one opening edge along the outer blade (32) of the flexible member housing chamber (8), there is provided a lid (7) supported by hinges (71) (71) and rotated up and down. On the inner surface of the lid (7), a convex portion (74) (74) that presses the flexible member (6) and forcibly protrudes from the hole (81) of the storage chamber (8) when the lid is closed. Is formed.
The convex portions (74) and (74) are such that the pressing force does not directly act on the outer blades (32) and (32) or deforms the outer blades (32) and (32) through the nonwoven fabric (60). The protrusion height and the outer blades (32) and (32) are formed so as not to act strongly.
Further, on the outer peripheral portion of the inner surface of the lid (7), the ridges (75), (75), (75) that press the outer peripheral portion of the flexible member (6) against the bottom of the flexible member accommodating chamber (8) when the lid is closed. ) Is formed.
On both sides of the free end of the lid body (7), locking pieces (72) and (72) for softly locking the lid body (7) in the closed state project, and the locking pieces (72) (72) On the outer surface, projections (73) and (73) are formed to engage and disengage from the recesses (83) and (83) (only one recess is visible in FIG. 8) formed in the wall surface of the flexible member housing chamber (8). Yes.

However, as shown in FIG. 4, with respect to the electric razor in the storage state with the head (3) covered with the cap (4), the fingernail of the cap (4) is put on the free end and lifted upward. The projection (73) of (72) and the recess (83) of the cap body (5) are disengaged to open the cap (4). The nonwoven fabric (60) soaked with oil is stored and set in the flexible member storage chamber (8).
As shown in FIG. 10, in a state where the lid (7) of the cap (4) is opened, the flexible member (6) remains in the flexible member accommodating chamber (8) in a flat plate state, and the flexible member (6) Does not contact the outer blades (32), (32), the sharpening blade (34), and the slit blade (38).

As shown in FIG. 9, when the lid (7) is closed, the projections (74) and (74) on the lid (7) press the nonwoven fabric (60), and the bottom of the flexible member accommodating chamber (8) is pressed. A part of the nonwoven fabric (60) protrudes from the hole (81) and is forcedly pressed against the outer blades (32), (32), the sharpening blade (34), and the slit blade (38). For this reason, the oil is reliably applied to these.
In addition, when the flexible member (6) is pressed against the outer blades (32) and (32), the oil seepage is improved, and the outer blades (32) and (32), the sharpening blade (34) and the slit blade ( The oil is applied more smoothly and effectively to 38).

  When the lid (7) is closed, the protrusions (75) (75) (75) on the outer peripheral edge of the lid (7) press the outer peripheral portion of the nonwoven fabric (60) to the nonwoven fabric (60). Since the impregnated oil is prevented from seeping out from the nonwoven fabric (60), the oil can be prevented from leaking to the outside of the flexible member housing chamber (8) and contaminating the periphery of the electric razor.

  The lid (7) is held closed by the locking pieces (72) and (72), that is, pressed against the nonwoven fabric (60). Use the electric razor with the cap (4) removed. After use, simply attach the cap (4) to the head part (3) again, and the non-woven fabric (60) infiltrated with oil hits the outer blades (32) (32). The oil is automatically applied to the shave blade (34) and the slit blade (38).

The oil applied to the outer blades (32) and (32) goes around the sliding contact surface with the inner blades (33) and (33), reduces friction on the sliding contact surface, and extends the life of the cutting blade. In addition, noise due to friction can be reduced.
As in the embodiment, the convex portion (74) on the inner surface of the lid (7) that presses the nonwoven fabric (60) is such that the pressing force of the convex portion (74) acts directly on the outer blades (32) and (32). If the outer blades 32 and 32 are deformed through the non-woven fabric 60, the caps 4 Even if the power switch (13) is turned on without removing the), the friction between the outer blades (32) and (32) and the inner blades (33) and (33) becomes too large. The trouble of biting the nonwoven fabric (60) between the inner blades (33) and (33) can be prevented.
When the cap (4) is put on the head (3), a switch (not shown) for turning off the power of the motor (15) is provided separately from the power switch (13) on the handle (1). If deployed, it is possible to reliably prevent the inner cutters (33) and (33) from reciprocating with the cap (4) covered.

  In the electric shaver according to the embodiment, since the gap between the inner surface of the main case (11) and the motor (15) is filled with the buffer piece (22), vibration and rotation noise of the motor (15) are reduced. .

As an electric razor aiming at the above-described mitigation effect, it is known to adhesively bond a rubber cushion piece (22) to the inner surface of the main case (11). In this case, the application of the buffer piece (22) is a manual operation, which is troublesome and causes variations in product quality. There is a possibility that the buffer piece (22) may be peeled off or forgotten to be attached.
Depending on the position of the buffer piece (22), it cannot be pasted.

As another example aimed at reducing the vibration and rotation noise of the motor (15), a large hole is opened in the part of the main case (11) corresponding to the motor (15), so that the outside of the main case (11). A push portion (not shown) that can close the motor (15) can be formed by filling the hole from the cover (2) covering the surface.
However, in this case, when the pressing portion hits the motor, the cover (2) bulges outward and the appearance is impaired. Also, when the palm hits the cover (5), the part corresponding to the motor feels hard and the user feels uncomfortable.

In the case of this embodiment, the cover (2) and the buffer piece (22) are continuous, and are integrally formed with the main case (11) by two-color molding or insert molding, so the buffer piece (22) is bonded. There is no need for joining, and the problem of peeling off or forgetting to stick the buffer piece (22) does not occur.
Furthermore, the wall of the main case (11) exists between the cover (2) and the buffer piece (22), and the buffer piece (22) and the cover are covered by a connecting portion (21) that fills a small hole in the wall. Since (2) is only connected, even if the buffer piece (22) is pushed by the motor, the cover (2) does not swell outward and does not impair the beauty.

  The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope described in the claims.

For example, the flexible member (6) of the embodiment is a non-woven fabric (60), but is not limited to this, and a flexible member (such as a cloth sheet, a sponge sheet, etc.) that has good oil penetration and is soft ( The material of 6) does not matter.
Moreover, a fragrance | flavor is apply | coated or impregnated to a flexible member (6), and the unpleasant odor from a head part, such as an outer blade (32), can be suppressed.

When the lid (7) is closed, the cap (4) of the embodiment presses the non-woven fabric (60) with the convex portion (74) on the lid (7), and the flexible member accommodating chamber (8) A part of the non-woven fabric (60) is projected from the hole (81) at the bottom and is put on the outer blades (32) and (32). When covered, the outer blades (32), (32) may enter the holes (81), (81) of the flexible member housing chamber (8) and hit the nonwoven fabric (60).
Alternatively, the flexible member housing chamber (8) may be omitted, and the flexible member (6) such as the nonwoven fabric (60) may be attached to the inner surface of the ceiling of the cap (4) with an attachment means such as adhesion, so that the oil is soaked.
