Description

[Detailed Description of the Invention] This invention relates to an electric shaver having a unique 9 mechanism.

This type of razor has a structure in which a blade block for sharpening is rotatably supported on the inner wall of a window formed in the head of the case body, and this blade block can be moved in and out through the window. There is something I did.

By the way, the blade block and the inner wall surface of the window are covered with hairs scattered during sharp cutting, so if you do not clean them frequently using a special brush, the hairs will fall on the blade block drive mechanism side inside the case body. This may cause the mechanism to malfunction.

However, in the above configuration, the blade block is pivotally supported by fitting support shafts protruding from both sides of the blade block into shaft holes formed in the window, and this blade block is attached to the window. Since the hair cannot be separated from the blade block or the inner wall of the window, it is impossible to clean the details 1 of the blade block and the inner wall of the window, and the lint is forced to remain.

Therefore, in this invention, a cutting edge block, which is arranged so as to be able to enter and exit through a window formed in the head of the case body, is removably fitted into the head of the case body. By holding the outer blade holder in a removable manner, if the outer blade holder is removed from the case body, the blade block itself can be removed from the case body, and this blade block and the inner wall surface of the window section can be removed. To provide an electric razor that can easily remove hair without leaving behind hair.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a case body, and a motor 3 fixed to a base 2 and a battery (not shown) are housed inside.

4 is an eccentric cam fixed to the rotating shaft 5 of the motor 2;
One end of a vibrating lever 7 is connected to the eccentric shaft portion 6 protruding from the eccentric cam 4, and the other end of the lever 7 is connected to a vibrator 8 disposed on the base 2. ing.

9, 9 are elastic arm pieces formed on both left and right sides of the base 2, and engaging portions 10 formed at the tips of each of these elastic arm pieces 9, 9 are connected to the side wall of the head 11 of the case body 10. exposed to the outside.

Reference numeral 12 denotes an outer cutter holder for holding a thin plate-shaped outer cutter 13 in tension;
Retaining parts 14 that are removably engaged with the retaining part 10 are formed on the left and right inner surfaces of the outer cutter 12, and when these engaging parts 10 and 14 are engaged, the outer cutter A holder 12 is detachably attached to the head 11 of the case body 10.

15 is an inner cutter body inscribed in the outer cutter 13, and this inner cutter body 1
The inner cutter holder 15 of No. 5 is connected to the tip of a drive rod 17 which is protruded from the upper surface of the vibrator 8, so that the inner cutter 15 reciprocates in the left-right direction (direction of arrow a). It has become.

18 is a compression spring for the inner blade body 15.

Reference numeral 19 denotes a window formed on the front surface of the head 11 of the case body 1, through which the edge cutting blade block 20 is inserted and removed.

The blade block 20 includes a holder 21, a fixed blade 22 held by the holder 21, a movable blade 24 pressed against the fixed blade 22 by a pressure spring 23, a spring receiving member 25, and the like.

As shown in FIGS. 3 and 4, the blade block 20 has support shafts 26 protruding from both the left and right sides, and the support shafts 26 are provided inside the window portion 19 on both left and right sides in correspondence with these support shafts 26. A shaft hole 27 is formed in the wall surface, and a notch 28 is formed in each shaft hole 27, which opens at the front surface 11a1 of the head 11 of the case body 1.
6 can be removed from the shaft hole 27.

The support shaft 26 fitted into each of the shaft holes 2T is inserted into the inner surface of the front wall 12a corresponding to the outer edge of the window 19 of the outer blade holder 12 fitted into the head 11 of the case body 1. The blade block 20 is prevented from coming off the hole 27, so that the blade block 20 is rotatably pivoted to the left and right inner wall surfaces of the protrusion 19.

29 is an operation button mounted on the front surface of the case body 1;
0 is a connecting member that is driven by the operation button 29 and constitutes a part of the drive mechanism 31 of the blade block 20, and elastic arm portions 33 are formed at both left and right ends of this connecting member 30, respectively.
A U-shaped engagement piece 35 is formed at each tip of the holder 21 to engage with engagement protrusions 34 formed at both left and right ends of the holder 21. By pushing up the operation button 29, the blade block 20 can be operated. It is configured to be stored in the position shown in FIG. 5, and to be projected to the position shown in FIG. 6 by pressing down the operation button 29.

In this way, when the outer cutter holder 12 is fitted into the head 11 of the case 1, the holder 12 prevents the support shaft 26 fitted into the shaft hole 27 from coming off, so the operation button 29 cannot be operated. Then, the edge cutting blade block 20 is rotated about the support shaft 26 and set at the protruding position, thereby being used for edge cutting.

If hair debris adheres to the inner wall surface of the blade block 20 or the window 19, remove the outer blade holder 12 from the head 11 of the case 1.
When the blade block 20 is removed from the case body 1, the support shaft 26 of the blade block 20 is removed from the shaft hole 27 through the notch 28 as shown in FIG. 7, and the blade block 20 can be removed from the case body 1.
This blade block 20 and window portion 19 can be thoroughly wiped with hair debris.

Furthermore, since the blade block 20 is configured to be detachable from the case body 1 side, the movable blade 24 and the like can be easily replaced.

In addition, when the blade block 20 is rotated and displaced as in this embodiment, by holding the support shaft 26 of the blade block 20 between the head 11 of the case body 1 and the outer blade holder 12, The mold structure of the bearing part is simplified.

In the above embodiment, the blade block 20 is rotatably displaced so as to be able to go in and out through the window 19. However, the structure is not limited to this, and the blade block 2
The present invention can also be applied to a configuration in which 0 is moved in and out of the window by sliding displacement.

As described above, this invention removes hair debris attached to the blade block by removably holding the edge cutting blade block that can be taken in and out from the case body between the outer blade holder and the main body. This can be achieved by providing an electric shaver that can be used easily.
