Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a structure in which the left and right reciprocating electric inner blades of an electric razor for men and a waste shaving machine for women can be rotated, and is further supported by two cylindrical rotary whetstones.
The present invention relates to a razor device equipped with a debris removing brush between elliptical inner blades and a foam soap injection hole with a check valve.

[0002]

2. Description of the Related Art The inner blade of a conventional waterproof electric razor is roughly classified into a circular rotary type and a left and right reciprocating type.

[0003]

The inner blade of the conventional waterproof electric razor has no structure of reciprocating left and right while rotating against a grindstone, and the edges of the blade are rounded.
There was a drawback that the hair was pinched and pulled. In addition, there is a drawback in that the gap between the blades is clogged with debris and it is difficult to clean, and thus the tips of the hairs are not sufficiently inserted.

It is an object of the present invention to provide a waterproof electric razor which is easy to clean and does not deteriorate in sharpness even after being used for a long period of time, has less irritation to the skin and hair roots, does not scatter hairs.

[0005]

In order to achieve the above object, in the waterproof electric razor of the present invention, two cushion springs are housed in a seesaw that changes the rotation of the motor into reciprocating motion, and two cushion springs are mounted on the seesaw. The support frame was placed via the frame support pins, and a hair removing brush, a cylindrical rotary grindstone, and a roller-interlocking rotary inner blade supported in contact with them were attached to the support frame. In addition, a hole with a check valve for pouring foamy soap from a cylinder equipped with a nozzle was provided in the box holding the outer blade.

The mechanism of the above-mentioned roller-interlocking rotary inner blade is
Ball bearings are in contact with the four sides of the square pillar-shaped mandrel of the roller that rolls against the skin along with the outer blade, and this ball bearing is placed between the groove and the support frame arranged in crosses on both sides of the cylindrical fixing material of the rotating inner blade. The inner blade can be rotated forward and backward at any time while reciprocating left and right. It should be noted that it is effective to provide V-shaped grooves on the four surfaces of the mandrel in order to reliably transmit the rotation of the roller and to smoothly reciprocate the left and right inner blades.

Further, in order to smooth the rotation of the roller and prevent the rotating inner blade from being excessively abraded, it is preferable to support the rotating inner blade so that both of the cylindrical ceramic grindstones can rotate on the support frame.

Further, in order to prevent local abrasion of the rotary grindstone, it is preferable to mount the rotary inner blade parallel to the surface perpendicular to the mandrel of the roller at a certain angle, so that the rotary inner blade does not have a circular center. Instead of an ellipse.

Further, hair debris accumulated between the blades of the rotating inner blade is removed, and foamy soap is made to flow into it to make the tips of the hairs slip easily. Furthermore, the hair debris and foamy soap are mixed to the outside. It is advisable to attach a hair removing brush to the support frame in order to prevent the hair from scattering and to facilitate cleaning of the hair.

In order to keep the balance of the support frame when only one of the rollers is rolled against the skin, a seesaw in which two frame support pins are supported by two cushion springs is attached to the motor drive shaft cam. It is good to attach.

[0011]

[Function] When the foam-like soap is injected into the soap injection hole of the waterproof electric razor configured as described above, the motor is driven and the outer blade and the roller are moved while touching the skin. The rotating inner blade reciprocates left and right while rolling on the surface of the skin. When the waste hair enters there, the hair is pressed against the edge of the outer blade by the edge of the rotating inner blade and is cut while being twisted.

Then, the shaved hair dust is mixed with the foamy soap flowing between the blades of the rotary inner blade and is scraped out by the hair dust removing brush attached to the lower portion of the support frame.

Further, as the inner blade rotates in conjunction with the roller, it is a portion supported by two cylindrical rotating grindstones attached to the support frame, and the surface of the rotating grindstone is between the edges of the inner blade. And the crushed edges grow naturally.

[0014]

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, the cam 1 is attached to the motor 11 of the waterproof electric razor.
0 is fixed, the crankshaft of the cam 10 is inserted into the crank portion of the lateral swing seesaw 9 hung at two fulcrums, and two cushion springs 17 are provided in the polyethylene frame provided at the upper portion of the seesaw 9 in FIG. The lid is covered with the spring cover 16 and the holding plate 18, and a notch for attaching and detaching the frame support pin 15 is provided on the frame edge. Two frame support pins 15 are fixed to the lower part of the support frame 7, and the rotary grindstone 6 is inserted into shaft holes formed on the left and right side surfaces of the support frame 7 so that both can be rotated. The debris removing brush 13 is attached to the central portion of the support frame 7 with a length of a certain degree. Then, with the tip of the hair removing brush 13 evenly inserted between the blades of the rotary inner blade 3, the rotary inner blade 3 is placed on the two rotary grindstones 6 to fix the rotary inner blade 3 in a cylindrical shape. The ball bearings are housed between the grooves arranged in the cross shape on both sides of the material and the support frame 7, and the square pole-shaped mandrel of the roller is passed through so that the four sides contact the ball bearings, and the rollers are fixed to both ends of the mandrel.

In FIG. 4, the outer blade 2 is an outer blade box 14
Has been hooked to play. The upper part of the outer cutter box 14 is cut out so that rollers can be rotated on both the left and right sides of the outer cutter 2. In addition, a hole with a check valve for pouring foamy soap from a cylinder with a nozzle was provided in the central portion of the outer blade box 14.

[0016]

Since the present invention is constructed as described above, it has the following effects.

Since the inner blade is shaved while shaving wasteful hair, the sharpness is not deteriorated, and the inner blade presses the hair and twists it, so that the sharpness is good.

Since the inner blade is partitioned by the outer blade and reciprocates left and right while rolling on the surface of the skin, irritation to pores and skin is reduced.

With the rotation of the inner blade, hair scraps are scraped out between the inner blades by the tip of the brush and mixed with the foamy soap, so that scattering of the hair scraps to the outside can be prevented. Moreover, washing with water becomes easy.
