Description

[Detailed description of the invention] This invention relates to an electric shaver.

The outer blades of reciprocating electric shavers have a larger surface area than regular rotary shavers, making them easier to shave, but the disadvantage is that the inner blades move back and forth, causing large vibrations that cause discomfort during use. In addition, when washing with water, the vibration of the inner cutter causes a water flow unlike the rotating type, which has the disadvantage that the water washing effect is less.Therefore, the object of the present invention is to reduce the area of the outer cutter to the same level as that of the reciprocating type. The purpose of the present invention is to provide an electric shaver that can reduce vibrations, suppress vibrations, and have an excellent flushing effect when applied to a flushable type.

An embodiment of the invention is shown in FIGS. 1 to 4.

That is, this electric shaver consists of a razor body 1 and a blade part 2, and the razor body 1' is in the shape of a raised cylinder. Protrudes from the hole. A waterproof ring 6 is attached to this hole and is in liquid-tight contact with the motor shaft 4. A battery 7 is loaded into the remaining space of the razor main body 1 from the lower end opening □, a cap 8 is screwed onto the bottom closure of the main body 1, and the battery 7 is pressed and fixed by a battery spring 9 provided on its inner surface. At this time, the anode of the battery 7 is supported by the anode plate 1.
0 is electrically connected to one terminal of the motor 3. Further, the cathode of the battery 7 contacts a connecting metal 11 laid on the inner surface of the razor body 1 via a battery spring 9, and a switch metal 012 is attached to the tip thereof, while the other terminal of the motor 3 is connected to a lead wire 13. The contact plate 14 is connected to a fixed contact plate 14 erected at the front end of the motor 3 through the mower 3, and the fixed contact plate 14 faces the end of the connecting fitting 11. The switch 12' is the switch 1
2 protrudes from the loading portion of the motor 3 of the main body 1 to the outside through a waterproof cover 15. Razor body 1
A mounting tube 16 having a mounting screw is provided around the husband wall 5, and the blade portion 2 is detachably attached to this mounting tube 16.

This blade part 2 consists of a cylindrical outer blade holder 17 having the same outer diameter as the razor body 1 and a helical (or screw-shaped) inner blade 8. A cylindrical closed opening 19 is formed, and a silk-like outer blade 20 that is stretched and bent into a semi-cylindrical shape using elasticity is attached to the opening 19, and its both ends are engaged with the inner edge of the opening row 9 by spring action. Also, one end of the outer blade holder 17 forms a female threaded cylinder 21 for mounting the main body and a bearing 22, and the end part forms a bearing 23 and a closing part 24 for removing whisker debris, and the outer blade shoulder reservoir cylinder 25 is extended.The inner cutter 18 has shafts 27, 27' protruding from both ends of the cylindrical body 26, and the torsion direction due to rotation in the same direction as the motor shaft 4 is on the side of the closed part 24 on the circumferential surface of the cylindrical body 26. "forming a spiral-shaped blade 28 with a feeding action in the direction of the axis 27';
Furthermore, a coupling 29 is attached to the shaft 27, and the inner cutter 18 is inserted into the outer cutter holder 17 from the opening row 9, and the shaft 27
' is inserted into the bearing 23, the shaft 27 is inserted into the bearing 22, the cutting edge of the blade is inscribed in the outer cutter 20, and the coupling 29 is attached. When the blade portion 2 is attached to the razor body 1 in this manner, the motor shaft 4 and the coupling 29 are connected. Further, the tip of the outer blade holder 17 attaches a cap 30 to the shoulder reservoir tube 25. The operation of this electric shaver is as follows.

That is, when the switch button 12 is pushed in, its contact portion is closed, the motor 3 is powered by the battery and operates, and the motor shaft 4
Due to this rotation, the inner cutter 18 rotates through the coupling 29. When the surface of the outer cutter 20 is placed on the chin of a human body and the beard is introduced through the cutter hole, the beard is cut by the cooperation of the inner cutter 18 and the outer cutter 20. The cut beard shoulder is sent out toward the tip by the rotation of the inner cutter 18, and is collected into the beard shoulder reservoir cylinder 25 through the opening □19. When cleaning, use cap 3
All you have to do is remove 0 and clean the beard stocking tube 25. When washing further with water, as shown in Fig. 2, when the blade part 2 is immersed in water A and the inner cutter 18 is operated, water is sucked through the cutter hole of the outer cutter 20 by the pump action of the inner cutter 18 and protrudes from the opening □24. A water stream is formed, thereby completely removing the beard shoulder attached to the inner cutter and the beard debris accumulated in the beard shoulder reservoir cylinder 25. With this structure, "this electric shaver can have the area of the outer cutter 20 the same as that of a reciprocating type, and since the inner cutter 18 does not vibrate back and forth, the main body 1 does not vibrate, and the inner cutter 18 has an axial direction feeding action, so that it is easy to remove the whiskers.

Furthermore, since the razor body 1' is completely waterproofed by the waterproof ring 6 on the motor shaft and the waterproof cover 15 on the switch, there is no problem with washing with water.

In some cases, the tube of the beard waste storage tube 25 is opened at the same time, and the beard shoulder is discharged by aligning this with the hole of the cap 30. As mentioned above, the electric shaver of this invention is
A helical inner cutter is provided on the inner surface of the reticulated outer cutter, and the rotation of this inner cutter cuts the beard, and the feed action of the inner cutter removes beard debris from the tip of the outer cutter holder, making it easy to shave. It is effective in that it has good elasticity, no vibration, is easy to clean, and can be washed with water.
