Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocating electric shaver, and more particularly to a mounting structure for a protective cap for protecting an outer blade.

[Prior art]

The protective cap 9 is provided to prevent the outer cutter 2 from being damaged by an external force, and is conventionally engaged with the outer cutter frame 23 or the electric shaver main body 1 as shown in FIG. It was attached by engaging the part 95.

[Problems to be solved by the invention]

In this case, the outer blade is not protected at the time of cleaning or repair, and the outer blade may be damaged or damaged. The present invention has been made in view of such a point, and its purpose is to always protect the outer blade except during use and when replacing the outer blade, and the outer blade may be damaged. It is an object of the present invention to provide a reciprocating electric shaver which has a very low risk of being damaged.

[Means for Solving the Problems]

Thus, the reciprocating electric razor according to the present invention includes a cartridge type outer blade having an outer blade body attached to an outer blade frame, and the outer blade is detachably mounted on an outer blade frame which is detachably mounted on the razor body. It is characterized in that a protective cap for protecting the outer blade is detachable from the outer blade frame. [Operation] According to the present invention, even when the outer cutter is removed from the outer cutter frame, the outer cutter can be protected by the protective cap. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. As shown in FIG. 6, a main body 1 of the electric shaver is provided with casings 11 and 12 formed of front and rear halves. The outer shell is constituted by a back panel 13 formed of a rubber-based member and arranged on the back of the casing 12 for
Inside this outer shell, a motor 41 and a pair of rechargeable batteries 40, 40 are arranged via a mounting base 15. A handle plate 50 is slidably mounted on the front surface of the casing 11, and a trimmer block 48 is rotatably mounted on the upper portion. This trimmer block 48
The handle plate 50 rotates in accordance with the vertical sliding operation. In the figure, reference numeral 51 denotes a lock handle. A driver 43 is housed in the upper part of the main body 1 as shown in FIGS. The driver 43 is connected to the motor 41
An elastic arm 43a engaged and coupled to an eccentric shaft 42 with an eccentric balancer mounted on the output shaft, and a pair of elastic legs 43b,
A boss 43c protruding from the upper surface side of the main body 1 and a fixing piece 43d located at the tip of each elastic leg 43b are integrally formed. The fixing piece 43d is fixed to the casings 11 and 12 by being fixed. Supported, the rotation of the eccentric shaft 42 is converted into a reciprocating motion by the bending of the elastic arm 43a and the elastic leg 43b. The inner blade 45 is attached to the boss 43c of the driver 43 via a push-up spring 44. Trimmer block 48 above
The driving force is transmitted from the driver 43 through the trimmer driver 49. Since the boss 43c reciprocates, dust on the upper surface of the main body 1 is protected by a dust protector 46 made of a rubber material. The ring-shaped dustproof body 46 has an inner peripheral edge covered with the boss 43c and an outer peripheral edge on the upper surface of the main body 1.
7, the boss 43c on the upper surface of the main body 1 is fixed.
Dust-proofing of the insertion opening. A cartridge type outer blade 2 is attached to an upper portion of the main body 1 via an outer blade frame 23. As is apparent from FIG. 4, the outer blade 2 in which the inner blade 45 slides on the inner surface includes an outer blade body 20 made of a thin metal plate, an outer blade frame 21, and a pair of holding plates 22, 2.
The outer blade main body 20 in a curved state is mounted so that the mounting projections 21c of the outer blade frame 21 enter into a plurality of holes 20a provided at both ends of the outer blade main body 20. Two
Both ends of 0 are fixed by a holding plate 22 having hooks 22b that engage with the outer blade frame 21. The cartridge-type outer cutter 2 is configured such that hooks 21 b formed on both side ends of the outer cutter frame 21 are attached to the outer cutter frame 23.
Protrusion 23b in slit 23a formed at the upper part of both ends
Is attached to the outer cutter frame 23 by engaging with the outer blade frame 23. The outer cutter frame 23 is attached to the main body 1 by a detachable button 18 that is engaged with the inner surface of the outer cutter frame 23 under the bias of a spring 19. The protective cap 9 which covers the outer cutter 2 and protects the outer cutter 2 is provided with a locking rib 90 at the lower portion of the inner surface thereof and with protrusions 91 and 91 serving as knobs at the upper ends at both ends. Pressing plate with locking rib 90 attached to outer blade frame 21 when covered
It is attached to the outer blade frame 21 by being locked to the lower side of the protrusion 22a protruding from the outer surface of each of 23 and 23. When the protective cap 9 is attached to the outer cutter 2 mounted on the outer cutter frame 23, both ends of the locking rib 90 on the inner surface of the protective cap 9 are indicated by 23c in FIG. The inner surface of the side portion is brought into contact with the inner surface of the side portion.
It does not move in the direction indicated by B in the figure. The protective cap 9 can be removed by pulling it up as shown in FIG. 7 by pinching the projections 91 at both ends. Since the protection cap 9 bends and the engagement between the locking rib 90 and the ridge 22a is released, the protection cap 9 can be removed. In addition to removing the outer blade 2 together with the outer blade frame 23 for cleaning the inner blade 45, etc., the protective cap 9 keeps the outer blade 2 even when removing the outer blade 2 from the outer blade frame 23.
Since the outer blade 2 is attached to the outer blade frame 21, the outer cap 2 can be kept protected by the protective cap 9. The operation of removing the outer blade 2 from the outer blade frame 23 is performed by pushing the operation portions 21a provided integrally at both ends of the outer blade frame 21 to flex the hook 21b, as shown in FIGS. No, it is carried out by pulling it up with it removed from the protrusion 23b. As shown in FIG. 11, the protective cap 9 may be one having both ends closed, but when both ends are open, the protective cap 9 is removed from the outer cutter 2 removed from the outer cutter frame 23. When it is necessary to remove the protective cap 9, it can be removed by laterally shifting the protective cap 9, as shown in FIG. The possibility of damaging the outer cutter 2 is significantly reduced as compared with the case where the protective cap 9 is removed by pulling up. By utilizing the fact that the protective cap 9 is attached to the cartridge type outer blade 2 as described above, here, as shown in FIG. The rear panel 13 made of a material is extended to the position of the outer cutter frame 23 so that slip can be reliably prevented. If the rear cover 13 is extended to both side surfaces, or if a concave groove corresponding to the finger shape is provided obliquely instead of the uneven stripe pattern, slipping can be performed more reliably.

【The invention's effect】

As described above, in the present invention, since the protection cap for protecting the outer blade is detachable with respect to the outer blade frame of the outer blade formed as the outer blade main body attached to the outer blade frame, The outer cap can be protected by the protective cap not only when the outer cutter is removed from the razor body, but also when the outer cutter is removed from the outer cutter frame. The outer blade can always be protected with a protective cap except when replacing the
There is very little risk of damaging the outer blade.
