Description

[Detailed Description of the Invention] The present invention relates to the inner blade of a reciprocating electric shaver, and its purpose is to facilitate the removal of shavings adhering to the inner blade, and particularly to effectively remove shavings from a water-washable type. .

A reciprocating electric shaver to which a first embodiment of the present invention is applied is shown in FIGS. 1 to 5. In other words, 1 is the razor body, 2 is the motor, 3 is the storage battery, 4 is the charging terminal pin, 5 is the charging electrical component,
6 is an eccentric shaft, 7 is a reciprocating conversion driver, 8 is a waterproof rubber, 9 is a joint, 10 is a connecting pin, 11 is an inner blade body,
12 is an outer blade frame, 13 is an outer blade frame attachment button, 14 is an outer blade, 15 is a switch handle, 1
6 is a trimmer handle, and 17 is a lead wire. When the motor 2 is activated by operating the switch handle 15, the driver 7 reciprocates via the eccentric shaft 6, and the inner blade 11 reciprocates. For this reason, outer blade 1
Cut off the hair that entered through the blade hole in step 4.

Now, the inner cutter body 11 has a cleaning body 18, and as shown in FIG.
The central portion of the tube is integrally connected by a central connecting body 20, and both ends are integrally connected by end connecting bodies 21 and 22, respectively, by simultaneous molding. In particular, the edge edges 19a at both ends of the inner blade 19 are prevented from protruding from the end connectors 21, 22. The connecting bodies 20 to 22 are connected to each other by a reinforcing circular arc bridge 23 of the inner blade 19 at a predetermined distance from the inner circular edge of the inner blade 19, and the end connecting bodies 21,
22 is attached to the joint 9. Further, the cleaning body 18 has an arcuate comb piece 24 having a width smaller than the gap width of the inner blade 19 and an arcuate length smaller than the arcuate interval between the central connector 20 and the end connectors 21 and 22;
A connecting rod 25 that arranges the comb pieces 24 at the same pitch as the inner blade 19 and connects them together.
and two sets of such configurations are included in the inner blade body 1.
1 from the longitudinal direction (arrow H) through the gap space between the bridge 23 and the inner blade 19, position each comb piece 24 between the inner blades 19, and connect the engaging portions 27 at both ends of the U-shaped connector 26. Connected to the connecting rod 25,
Make it one. The cleaning body 18 has the ends of the comb pieces 24 supported on the upper surface of the central connector 20, but may be supported by the end connectors. In this way, the cleaning body 18 can freely move up and down, left and right, and back and forth.

Even if the inner cutter body 11 starts reciprocating motion due to the operation of the motor 2, the cleaning body 18 is free with respect to the inner cutter body 11, so the inner cutter blade 19 moves toward the cleaning body 18.
The comb piece 24 collides with the comb piece 24, and receives an impact from the comb piece 24 every time it reciprocates. Therefore, shaving debris is less likely to adhere to the surface of the inner cutter blade 19 due to cutting the whiskers, and even if it does adhere, it can be easily removed. Furthermore, since there is a water flow effect when washing with water, it can be removed even more reliably.

With this structure, the inner blade of this reciprocating electric shaver has the following effects. That is, (1) Since the cleaning body 18 is freely disposed between the inner blades 19 and collides with the cleaning body 18 by the reciprocating movement of the inner blades 19, warping debris does not adhere to the inner blades 19. less difficult and easier to clean. In the case of the water-washing type, the inner blade 19 can be reliably cleaned and automatic cleaning is facilitated.

(2) Since the cleaning body 18 was supported by the connecting body 20,
There are differences in the following points compared to those supported by the razor body. That is, when the support base is disposed on the razor body, the cleaning body 18 needs to be raised between the inner blades 19 from both ends of the inner blades 19.
It becomes necessary to make both ends of the inner cutter blade 9 protrude outward, and the outer cutter is damaged at the end corner edge 19a of the inner cutter blade 19. However, in the case of the embodiment, the edge 19
There is no need for a to protrude from the connecting bodies 21 and 22.

(3) Since the comb piece 24 of the cleaning body 18 is made into an arc along the shape of the inner blade 19, the inner blade 1
9 can be collided with almost the entire part, and the removal of warp debris becomes more reliable.

A second embodiment of the invention is shown in FIGS. 6-9. This is because the arc length of the comb piece 24a of the cleaning body 18a is within the distance between the end connecting bodies 21 and 22, and the comb piece 24a of the cleaning body 18a is
4a are connected to each other by a connecting part 28 which is integrally provided on the outside during molding, and on the other hand, a communicating hole 29 is formed on the same straight line inside, and this communicating hole 29 is located on both sides of the central connecting body 20. I have to. This comb piece 24a is inserted into the gap between the bridge 23 of the inner cutter body 11 and the inner cutter blade 19, and the connecting rod 30 is press-fitted into the communication hole 29 from the lateral direction inside the inner cutter blade 19, or is glued or welded through the connecting rod 30. do. Next, cleaning body 1
When the comb pieces 8a are set with a jig and the connecting portions 28 are cut and removed using a lathe or grinder, each comb piece 24a is removed.
is supported by the central connector 20. In addition to the effects of the first embodiment, this embodiment has the advantage of easy assembly.

A third embodiment of the invention is shown in FIGS. 10 to 1.
Shown in Figure 2. In this case, the cleaning body 18b has an integral structure as shown in FIG. That is, the base 3
Reference numeral 1 is U-shaped and corresponds to the length of the inner blade body 11, and has a concave space into which the central connecting body 20 is loosely fitted. In addition, each comb piece 24b extends from the upper edge of the base 31 on both sides by an arc of about 1/4, and the comb piece 24b is connected to a connecting portion 32 for preventing deformation.
The ends of 4b are connected. This cleaning body 18b passes through the central connecting body 20 from the bottom side of the inner cutter body 11 while narrowing both sides of the base 31 inward, and positions both ends of the comb piece 24b from inside the end connecting bodies 21 and 22 to the top surface thereof. and supported on its upper surface (10th
figure). This embodiment is even easier to install than the second embodiment.

As described above, in the inner blade of the reciprocating electric shaver according to the present invention, the cleaning body is arranged in the gap between the inner blades and between the end connecting bodies, and the cleaning body is collided with the cleaning body by the reciprocating movement of the inner blade. As a result, the swarf adhering to the inner blade is removed, so the swarf adhering to the inner blade can be automatically removed, and there is no need to make the outer corners of both ends of the inner blade protrude. .
