Description

[Detailed Description of the Invention] The present invention relates to an electric shaver that allows the user to easily and safely adjust the blade pressure between the outer cutter and the inner cutter.

The blade pressure between the outer and inner blades of conventional electric razors is set at the time of design and adjusted by the manufacturer, and as a result, the user uses it and hair particles adhere to the inner blades, which increases the load. If the blade pressure fluctuates due to aging or aging, the user will not be able to adjust the blade pressure, and as a result, excessive current will flow to the motor that drives the inner blade, shortening the battery usage time. There were drawbacks.

The present invention relates to an electric shaver that eliminates the above-mentioned drawbacks.

An embodiment of the electric shaver of the present invention will be described below with reference to the drawings.

The electric shaver of the present invention includes a motor 2 disposed within a main body 1, and a mounting portion 5 having a flat abutment portion 4 on a part thereof as shown in FIG. provided, the rotating shaft 3
A mounting hole 8 in which a flat contact part 4 is formed to contact the flat contact part 4 of the mounting part 5 of the rotating shaft 3 is provided in the inner cutter stand shaft 6 which is mounted to the mounting part 5 of the rotating shaft 3. The above-mentioned inner cutter stand shaft 6 is attached to the attachment part 5 of the shaft 3.
The mounting hole 8 is connected to the flat contact portion 4 of the mounting portion 5.
The inner cutter stand shaft 6 can be slid on the rotating shaft 3 in the axial direction (vertical direction in FIG. 1) and in the rotational direction. The inner cutter stand 10 is attached to the inner cutter stand shaft 6 so as to be removable and rotated by the inner cutter stand shaft 6.
The inner cutter 11 is connected to the outer cutter 12 by a spring (not shown).
The outer cutter 12 is placed with a biasing force applied in the direction of the outer cutter frame 1.
3, a threaded portion 14 is formed on the outer peripheral surface of the outer cutter frame 13, and a threaded portion 15 that is screwed into the threaded portion 14 of the outer cutter frame 13 is formed on the blade holder 16. The threaded part 14 of the outer cutter frame 13 is screwed into the threaded part 15 of the outer cutter frame 16 and detachably attached, and the U of one end of the lever 18 is inserted into the recessed part 17 formed on the circumferential surface of the inner cutter base shaft 6. The inner cutter base shaft 6 is rotatably held by a lever 18 by loosely fitting a letter-shaped holding portion 19 thereinto, and a pivot 20 is provided at the center of the lever 18, and the pivot 20 is connected to the partition wall of the main body 1. The lever 18 is pivoted to a pivot holding portion 22 formed in the
A holding protrusion 2 that allows the pivot support 22 to hold the pivot support 20 of the
3, and a sliding groove 25 is provided on the inner surface of the heir 26 which is inclined within a predetermined range in which the actuating part 24 at the other end of the lever 18 is fitted and the actuating part 24 is moved in the vertical direction in FIG.
A sliding hole 27 for sliding the legitimate child 26 within a predetermined range is provided across the main body 1 and the blade holder 16, and a sliding holding portion 28 for slidingly holding one of the legitimate children 26 is provided in the blade holder. 16 bottom 2
A sliding holding part 30 is provided on the dividing wall 21 of the main body 1, and the second child 26 is slidably held by the respective sliding holding parts 28 and 30. The blade holder 16 is arranged to be slidable in the sliding hole 27, and the blade holder 16 is detachably attached to the main body 1.

In the above configuration, the vertical movement state of the holding part 19 of the lever 18 with respect to the movement of the legitimate child 26 is as shown in FIGS. 5a to 5C, and FIG.
In this case, the holding part 19 of the lever 18 is located on the same line as the actuating part 24 of the lever 18, and as shown in FIG. slides the heir 26 and places the lever 18 at the highest position of the sliding hole 25 of the heir 26 (a position higher than the pivot point 20 by the Y dimension).
In this case, the lever 18 is
The holding part 19 of the lever 18 moves downward around the pivot part 20 of the lever 18, and the holding part 19 of the lever 18 is located at the lowest position (a position lower than the pivot part 20 by the Y dimension).
Figure C shows a case where the eldest child 26 is slid and the actuating part 24 of the lever 18 is positioned at the lowest position of the sliding hole 25 of the eldest child 26 (a position lower than the pivot part 20 by the Y dimension); in this case, the lever The holding part 19 of the lever 18 moves upward around the pivot part 20 of the lever 18, and the holding part 19 of the lever 18 is located at the highest position (a position higher than the pivot part 20 by the Y dimension). In this way, the holding part 19 of the lever 18 is moved up and down by the heir 26, and the inner cutter shaft 6 is moved in the vertical direction (axial direction) with respect to the rotating shaft 3, and the inner cutter attached to and detached from the inner cutter shaft 6 is moved. The blade pressure of the outer cutter 11 and the inner cutter 12 provided on the inner cutter stand 10 is adjusted by moving the stand 10 up and down.

Further, in FIG. 4, reference numeral 32 denotes a shielding plate disposed between the main body 1, the inner receiving stand 16, and the eldest child 26 to prevent the inside from being seen from the outside.

In the electric shaver configured as described above, the motor 2 is energized, the motor 2 rotates the inner cutter base 10, and the inner cutter 11 and the outer cutter 12 of the inner cutter base 10 cut hair, etc. It is something to do.

If hair particles adhere to the inner blade 11 etc. during use and the blade pressure of the inner blade 11 fluctuates and the load on the motor 2 increases, or if the blade pressure of the inner blade 11 fluctuates due to aging, legitimate child 26
The blade pressure of the inner cutter 11 and the outer cutter 12 can be adjusted to the predetermined optimum blade pressure by operating the blade.

Since the electric shaver of the present invention has the above configuration,
The blade pressure between the outer blade and the inner blade can be easily and safely adjusted by the user as appropriate, and the blade pressure can be easily and reliably adjusted each time to suit the type of beard, etc. of the user. It can reliably cut hairs, etc., and the user can easily prevent excessive current from flowing to the motor that drives the outer blade, extending battery usage time (life). .
