Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a rotary electric shaver, and is for the convenience of cleaning the rotary inner blade.

[Conventional technology]

The rotary electric shaver is known, for example, from Japanese Utility Model Publication No. 48-42304 and Japanese Patent Publication No. 56-104689. There, the rotary inner blade can be removed from the main body case and cleaned.

[Problems to be solved by the device]

However, it is desired that the rotary inner blade can be cleaned with a brush or the like even when it is attached to the main body case in order to simplify the cleaning. In this case, when the rotary inner blade is attached to the main body case, only the upper part of its circumference is exposed from the main body case.To clean the entire circumference, touch the rotary inner blade directly with your fingers to add points. It is necessary to clean while doing. However, in this case, there is a risk of injuring the fingers with the inner blade edge, and it may cause rust due to sweat or fat on the inner blade.

The present invention has been made to solve these problems, and an object thereof is to ensure the safety of cleaning the rotary inner blade.

[Means for Solving the Problems]

In the rotary electric shaver of the present invention, for example, as shown in FIG. 1, a rotary knob 20 is provided on the main body case 1 at a position outside the bearing portion supporting both ends of the rotary inner blade 13, and the rotary knob 20 The rotary inner blade 13 can be manually rotated.

[Action]

At this time, the rotary inner blade 13 can also be rotated by the rotary knob 20 while cleaning the entire circumference thereof with a brush or the like, and can be cleaned without directly touching the rotary inner blade 13 with a finger.

[Effect of device]

According to the rotary electric shaver of the present invention configured as described above, it is possible to clean the entire circumference of the rotary inner blade 13 while rotating the inner blade 13 without directly touching it, so that it is extremely safe to clean. Further, it is possible to prevent sweat and oil from adhering to the inner blade 13 of the rotary.

〔Example〕

An embodiment of a rotary type electric shaver according to the present invention
A description will be given with reference to FIGS.

1 and 2, a fixed socket in which a circuit board 2 and a rechargeable battery 3 are incorporated in a lower half portion of a main body case 1 of the main body case 1, and power can be supplied to a bottom of the case via a power cord. 4 and a movable plug 5 for charging, which can be inserted into a wall outlet or the like, are selectively mounted so as to be usable.

A mesh-shaped outer blade 6 is mounted on the upper portion of the main body case 1 via a holder 7 of the outer blade 6 so as to be curved in an arch shape. The left and right wall portions of the holder 7 of the outer blade 6 are engaged and supported by the knob-attached locking claws 9 which are removably mounted on the left and right upper ends of the main body case 1 via springs 8, respectively. Therefore, when the left and right knob-fitting claws 9 are pushed against the spring 8, the holder 7
Can be removed from the main body case 1 together with the outer blade 6.

In the upper half of the body case 1, left and right support frames 10 ・ 10
Is vertically movably incorporated so that its upper end portion 10a, 10a projects upward from the slit 12 of the upper wall 11 of the main body case 1,
Between the upper end portions 10a and 10a, a cylindrical rotary inner blade 13 that is in sliding contact with the inner surface of the outer blade 6 is horizontally supported. In addition, a motor 15 is attached to the same frame 10 in the main body case 1,
Also, a gear transmission type drive transmission means 16 for transmitting the rotation of the motor 15 to the rotary inner blade 13 is mounted.

The shafts 17 at the left and right ends of the rotary inner blade 13 are at the left and right support frames 10.
The upper end portion 10a of 10 is rotatably supported via bearings 18 and 19. The shaft 17 protruding from the bearing 19 at the right end is transmission-coupled to the drive transmission means 16 provided on the right support frame 10.
A rotary knob 20 is inserted at the end of the shaft 17 protruding outward from the bearing 18 at the left end, and the rotary inner blade 13 can be manually rotated by grasping the rotary knob 20 with a finger.

It is preferable to provide a non-slip means such as a knurl on the peripheral surface of the rotary knob 20. Further, as shown in FIG. 2, it is more preferable to provide a groove 23 on the end face of the rotary knob 20 so that the handle 22 of the cleaning brush 21 or the tip of a screwdriver or the like can be inserted and rotated.

Now, in order to clean the rotary inner blade 13, the drive of the motor 15 is stopped, the outer blade 6 is removed together with the holder 7 from the upper part of the main body case 1, and then the rotary inner blade 13 is cleaned with a cleaning brush 21.
Etc. clean it. At this time, the rotary knob 20 may be rotated with a finger as shown in FIG. 3, or the cleaning brush 21 as shown in FIG.
Since it is possible to clean while rotating the rotary inner blade 13 by rotating it with the tip of the handle 22 or the like, the entire circumference can be cleaned without directly touching the rotary inner blade 13 with a finger. Therefore, it is possible to safely clean the entire circumference without danger of cutting a finger with the cutting edge.

As shown in FIG. 1, a transparent window 25 may be provided on the side wall of the outer blade holder 7 so as to correspond to the rotary knob 20 so that the rotary knob 20 can be seen from the outside. In this case the rotary knob
If you color 20, you can see the rotation well.

[Another embodiment]

As shown in FIG. 4, the rotary knob 20 and the end of the shaft 17 may be transmission-coupled by a gear 24. In this case, if the rotary knob is formed as large as possible, the rotary inner blade 13 can be smoothly rotated with a light force.

The present invention can be similarly applied to a rotary inner blade 13 and left and right bearings 18 and 19 which are integrally combined into a unit and which is detachably attached to the support frame 10.
