Description

DETAILED DESCRIPTION OF THE INVENTION C. Technical Field of the Invention The present invention relates to a reciprocating electric shaver equipped with a cutting blade formed by a flexible plate-shaped outer cutter stretched over an outer cutter case.

[Conventional technology]

A conventional reciprocating electric shaver has a structure as shown in FIG. That is, 1 is a main body case with a built-in motor 2, and 3 is an outer cutter case detachably attached to this main body case, and the upper part is open.

Reference numeral 4 denotes a flexible plate-shaped outer cutter, which is inserted into the outer cutter case 3 from the inside so that the cutter surface is exposed from the opening in an arch shape.

5 is a vibrator that is engaged with the rotating shaft 6 of the motor 2 via a connecting shaft 8 having an eccentric shaft 7; 9 is an inner blade having an arcuate blade surface fixed to this vibrator; The inner surface of the outer cutter 4 is elastically pressed.

By the way, the outer cutter 4 is a plate-shaped piece bent into an arch shape at the center as shown in Fig. 1, and is mounted inside the outer cutter case 3. Due to the sliding contact of the blades, the outer blade 4 will wear down and the cutting edge will fall off.
It is necessary to replace the outer blade 4 with a new one at an appropriate time.

That is, according to such a conventional structure, when the outer cutter wears out, only the outer cutter must be replaced each time, which forces the user to bear extra costs.

[Summary of the invention]

This invention eliminates the above-mentioned drawbacks by mounting the outer cutter in such a way that its arched portion consists of half of one side of the blade surface, so that when the outer cutter wears out, the remaining portion can be used. The arch-shaped part can be replaced and configured, allowing one outer blade to be used twice, and the main body case located on the opposite side of the blade storage section stores the unused half of the blade. It is an object of the present invention to provide a reciprocating electric shaver having a shaving blade storage section in the upper part of one side.

[Embodiments of the invention]

The present invention will be described below with reference to an embodiment shown in FIGS. 2 to 4. Reference numeral 11 denotes a main body case, and a motor 13 is screwed to a mounting plate 12 by screws 14. Reference numeral 15 denotes a connecting shaft fixed to the rotating shaft 16 of the motor 13, and a broken shaft 17 is provided at the upper end of the connecting shaft 15 at a predetermined distance from the axis.

Reference numeral 18 denotes a vibrating body that converts the rotational output of the motor 13 into reciprocating motion.
At the same time, a vibration shaft 2o integrally provided at the center of the upper surface of the main body case 11 is made to protrude to the outside through a through hole 21 provided on the upper surface of the main body case 11.

Reference numeral 22 denotes an outer blade case that is detachably attached to the head of the main body case 11 and has an open top.

Reference numeral 23 denotes a locking tool for the outer cutter case 22 that is provided on the side surface of the main body case 11 so as to be freely retractable, and is pressed in the locking direction by a compression spring 24. Reference numeral 25 denotes an outer cutter inserted into the inner side of the outer cutter case 22 from the lower part and arranged so that the blade surface is exposed in an arch shape from the opening on the upper surface, and this has flexibility as shown in Fig. 3. By bending the plate-shaped material at a position biased to one side, an arch-shaped portion is formed on approximately half of one side of the blade surface and is exposed to the outside.

26 is a blade holder movably attached to the vibration shaft 20 of the vibrating body 18, 27 is a C ring for preventing the blade holder 26 from being removed, and 28 is an inner blade fixed to the blade holder 26, which has an arc-shaped blade. It is composed of multiple blades with faces. 29 is a coil spring that presses the inner cutter 28 against the inner surface of the outer cutter 25; 30 is a sealing plate that covers the upper surface through hole 21 of the main body case 11 to prevent hair chips from entering;
Reference numeral 1 denotes a blade surface storage portion formed on the inner side of the outer cutter case 22 and stores the half of the blade surface that is not exposed. 32 is provided in the upper part of one side of the main body case 11 so as to be freely retractable. 20 for reciprocating motion to trim the rice ridges, and is provided on the opposite side of the blade storage section 31. Reference numeral 33 denotes a scraping blade storage portion that stores the scraping blade 32.

In the above configuration, when the motor 13 is driven, the vibrating body 18 reciprocates via the flawed shaft 17 of the connecting shaft 15, so the inner cutter 28 reciprocates while being in contact with the inner surface of the outer cutter 25, thereby cutting the beard. disconnect. If the blade surface of the outer cutter 25 wears out, remove the outer cutter case 22 from the main case 11, pull out the outer cutter 25 from inside, and then change the orientation to remove the blade surface that is not yet used. One side of the blade is bent into an arch shape and reattached so as to be exposed from the opening of the outer blade case 22, and the worn blade surface is positioned in the blade storage part 31. Here, according to the embodiment of the present invention, the blade surface storage portion 31 provided on one side of the outer blade case 22
Scrape blade 32 on the opposite side where the outer blade 25 does not touch.
Since the cutting blade storage section 33 is provided to store the blade, the space of the main body case 11 and the outer blade case 22 can be effectively utilized, which can greatly contribute to the miniaturization of the product.

〔Effect of the invention〕

As described above, this invention has a configuration in which a blade storage section for storing one half of the outer cutter is provided on one side of the outer cutter case, and a cutter is installed on the opposite side of this blade storage section.
A single outer cutter can be used for a long period of time by replacing the blade surface, space can be used more effectively, and the product can be made smaller.
