Description

[Detailed description of the invention] This invention relates to a vibrating electric shaver, and the purpose of this invention is to make it extremely compact and convenient to carry by effectively arranging the various parts that are housed in the case without using batteries as the power source. It is something to do.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an electric shaver body, and the upper part of the body case 2 has an outer cutter 3 made of a thin metal plate with a number of holes for introducing hairs into an S-arch shape. The outer cutter frame 4, which is held in shape, is removable, and a vibration drive blade 5 that slides against the inner surface of the outer cutter is disposed within the outer cutter frame.

The main body case 2 has a partition wall 6 formed on its upper surface to separate it from the inside of the outer cutter frame 4.

On one side of the main body case 2, dry batteries 7, 7 are arranged with a small gap S between them and the partition wall 6, and on the other side, the dry batteries 7, 7 are arranged with a height smaller than that of the dry batteries 7, 7. An electric motor 8 is disposed with a large gap S' between it and the partition wall 6.

In the gap 9 formed across the small gap S and the large gap S', a vibrator 1 converts the rotational driving force of the electric motor 8 into a reciprocating driving force and transmits the force to the vibrating drive blade 5.
0 is set.

The vibrator 10 is made of a molded synthetic resin material, and has a mounting base 13 formed at one end thereof, which overlaps the head portion 11 of the electric motor 8 and is fixed with a screw 12 or the like. electric motor 8
A thin vertical support piece 15 is formed vertically along the rotating shaft 14, and a cam play part 17 is provided on the upper side of the thin vertical supporting piece 15, which is loosely engaged with the eccentric cam shaft 16 fitted on the rotating shaft 14. A sliding piece 19 that extends along the small gap S and slides back and forth within the small gap is formed on the other side opposite to the small gap S, and the eccentric cam When the shaft 16 rotates, the cam play portion 17 of the vibrator 10 moves against the vertical support piece 1.
5 to smoothly follow the reciprocating motion without being pulled upward, and the sliding piece 19 formed at the other end can be smoothly slid within the small gap S.

Reference numeral 23 denotes a vibrator support fitting provided corresponding to the electrode portion 18 of the dry battery 7 and within the small gap S, so as to come into sliding contact with the sliding piece 19 of the vibrator 10.

That is, it functions to reduce the frictional resistance during sliding movement of the vibrator 10.

20 is a substantially central portion of the vibrator 10, that is, the cam play portion 1;
A drive shaft is integrally formed between the sliding piece 7 and the sliding piece 19 and extends upwardly, and passes through a through hole 21 bored in the partition wall 6. The drive shaft is engaged with the vibration drive blade 5, and the drive shaft is The vibration drive blade 5 is driven by a coil spring 22 wound around the outer periphery.
is one that effectively slides into pressure contact with the outer cutter 3.

In the above embodiment, two dry batteries 7 are arranged side by side, but only one battery may be used, and it goes without saying that in that case, the width dimension can be further reduced.

As described above, the electric shaver according to the present invention makes effective use of the remaining space for each component arranged inside the main body case, so that the electric shaver has a small external shape and is suitable for carrying.

Claims (1)

[Scope of utility model registration request] In an electric shaver, a removable outer cutter frame is formed on a partition wall soil formed above the main body case, and a vibration drive blade is disposed within the outer cutter frame, and the partition wall is located on the lower side of the partition wall. A dry battery is placed in a small gap with the partition wall, and a DC motor is placed in parallel with a large gap formed with the partition wall on the other side. Therefore, a vibrator driven by the electric motor is disposed, and the vibrator has a cam play part formed at one end to play with an eccentric cam shaft fitted to the rotating shaft of the electric motor, and a cam play part formed at the other end to play with an eccentric cam shaft fitted to the rotating shaft of the electric motor. An electric shaver comprising a sliding piece that slides in a gap, and a drive shaft that passes through a hole bored in the partition wall between the sliding pieces and engages with the vibrating drive blade.
