Description

[Detailed Description of the Invention] This invention provides a razor head + TB having inner and outer blades that can be tilted in the front and rear direction.
This invention relates to an improvement in an electric shaver that is easy to apply and convenient to use.

In addition to the first battery that is normally used, this type of electric shaver has a second built-in battery as a backup power source.
Providing a switch for selectively switching between the battery and the second battery provides the following secondary advantages. However, when using a rechargeable battery as the first battery for normal use, if the battery capacity of that battery decreases due to use, a spare second battery can be used by operating the selector switch. , without waiting for the time required to charge the first battery.
There is the convenience of being able to use this razor immediately even after the capacity of the first battery decreases.

However, in this case, if the changeover switch is operated by one shared operation knob, the operation knob will be moved to switch between two positions: the first battery drive position and the second battery drive position. According to this, sometimes the vehicle accidentally moves to the second battery drive position when it should have stopped at the first battery drive position.

If you use it without noticing this, the capacity of the second battery will decrease unexpectedly, and you will have to use the spare second battery when you want to use it.

In addition, if a single selector switch operation knob is used to drive both the 1st battery and the 2nd battery, the frequency of use of the shared operation knob will increase, and the operation knob may be damaged or malfunction at an early stage. This can easily lead to the worst case scenario where both the first battery and the second battery cannot be driven.

Focusing on this fact, this invention has developed the first
Assuming that a battery and a spare second battery are built-in, by making it possible to open and close the power supply to the load of each battery independently using a dedicated switch operation knob, the "dual battery" The first purpose is to prevent erroneous operations such as the conventional case in which the load is driven by the second battery when it should be driven by the first battery.

A second purpose is to minimize damage and failure of the operating knob of the first battery 1 used during the suspension.

Furthermore, in an electric razor whose head part can be tilted back and forth, when using the gi, 1 part of the spatula is 1111 car (if used with a handrail, 1 part of (L-[j (i, l1 song) +iii of the main case with the front side facing you
＋'itif! When using it, hold it in a grasping position with both thumbs hanging, and then tilt the throat part backwards to use it. You will use it in a gripping position where your thumb hangs over the rear side of the main case. In other words, when using the main unit, hold the main case with your thumb or the tip of the throat.
It can be changed so that it can be hung on the front or back of the main case depending on the direction of the item. This invention focuses on the above, and by arranging the first switch operation knob and the second switch operation knob on different surfaces of the front and rear surfaces of the main body case, which are arranged in the direction of inclination of the head part, one vehicle The third purpose is to make the edge knob easier to use, to prevent misidentification and confusion in its operation, and to improve usability.

The details will be explained below based on the drawings.

1 to 3 show an embodiment of an electric shaver according to the present invention, the main body case 1 of which has a throat portion 2 that extends in the front-rear direction (for example) at its upper part.
- The throat portion 2 includes an external force 3 and an inner cutter 4 that slides into contact with the inner surface of the external force 3. A・GJ in body case 1,
and a motor 5 that drives the inner cutter 4.

A first battery 6 for normal use and a second battery 7 for backup are built in to supply power to the motor 5. The first battery 6 and the second battery 7 may be either storage batteries or dry batteries, and it does not matter whether they are rechargeable or not. For example, the first battery 6 is a single-ball type Nisokerka F Mium storage battery, and the second battery 6 is a Nisokerka F-Mium storage battery. The xT uses single-cell type dry batteries with different battery capacities.

The first switch operating knob 8 opens and closes the energizing circuit of the motor 5-1 of the second Kameike 6, and the second switch (7) Eisaku knob opens and closes the energizing circuit of the second battery 7 to the motor 5. 9 are attached 4J to the front and rear surfaces 1a and 1b of the main body case 1 having a rectangular cylindrical shape, respectively. Both the first switch operating knob 8 and the second switch operating knob 9 have a bush type operation mode, and the knobs 8 and 9 are connected via an operating rod 10 protruding from the knob 8 side. The operating rod 10 is the operating piece 1
1 and interposed in the drive circuit of the first battery 6 as shown in FIG. and the contact 1 between the books inserted in the circuit that drives the second battery 7.
4, on the contrary, it is disposed on the side in the moving direction of the actuating piece 11 which is moved by the button operation of the second switch operating knob 9.

In such cases, when using this razor,
7 (a) and press the first switch operation knob 8 on the tilted side with the thumb of the gripping hand.
), the contact 13 is closed, the motor 5 and the first battery 6 are connected, and the motor 5 is driven. Next, the first
If the capacity of the battery 6 decreases or continues to be used without noticing this decrease in capacity, the motor 5 will not be driven and will become unusable even if the first switch FM switch 8 is turned on. . Therefore, at this time, the second battery 7 is used, but at this time, the head part 2 is tilted backward, and the thumb of the gripping hand is placed on the rear surface of the main body case 1.
] If you switch your hand so that it is facing up and operate the second switch operation knob 9 on the rear surface 1bl with your thumb, the second battery 7 will be placed on the contact 14 side or the closed motor 5 as shown in FIG. 7(b). The battery 7 drives the motor 5.

In addition, in FIG. 3, the second switch operation knob 9 should be careful not to be pressed accidentally in this state.

Slide lock tool 15 at the bottom of the first switch operation knob 8
When the slide locking tool 15 is connected to the first switch operation knob 8, the second switch operation knob 9 can be pressed.

The second switch operating knob 9 can be pressed by disengaging and tightening the slide locking tool 15.

Incidentally, according to the switch operation mechanism shown in FIG. 3, even if the slide locking tool 15 is removed.

Even if both knobs 8 and 9 are operated at the same time, both switches will not be turned on.

In addition, contrary to the above embodiment, the first switch operation knob 8 may be arranged on the rear side of the main body case 1, and the second switch operation knob 9 may be arranged on the front side of the main body case 1. Further, the motor 5 may be replaced with an electromagnet. Further, as long as the electric shaver has an internal and external force and allows the shaver section 2 to be tilted in the front-rear direction, it may be of a vibrating type or a rotating type.

FIGS. 4 and 5 both show other modified embodiments of the lock flat stage of the switch operating knob, in which the locking means of the switch operating knob can be moved to the second switch by manual operation of the slide locking tool 15 alone.・In contrast, in these modified embodiments, the first switch operation knob 8 and the first switch operation knob 9 are not operated in conjunction with the tilt operation of the razor head 2 (de 1 operation). This makes one of the two-switch operation knobs 9 inoperable.

That is, in the modified embodiment shown in FIG.
Inside, above the first switch operating knob 8 and the second switch operating knob 9, slide locking devices 15 and 15 are respectively provided so as to be movable up and down so as to engage and disengage from each knob 8 and 9, and each spring 16 Just press the slide locking tool 15 on the top f! I) bias in the direction. Each slide locking tool 15 has a pressed portion 15a and a knob engaging/disengaging portion 15b at upper and lower sides θ1jA, and the pressed portion 15a is urged to protrude from the upper wall IC of the main body case 1 by the spring 16. In this case, when the razor head section 2 is tilted forward, the slide locking tool 15 on the first switch operation knob side is pressed against the pressed section 15a by the head section 2, and the upper outer side Q of the first switch operation knob 8 is pressed. At this time, the first
The switch operation knob 8 can be operated by a button, but the second
Button operation of switch operation knob 9 becomes impossible, and the second
Erroneous operation of the switch operation knob 9 can be prevented. On the other hand, if you tilt the first razor head part 2 backward, the second switch will open.

Since the slide port 15 on the side of the switch operation knob 9 engages with the upper outer side of the second switch Ii operation knob 9, at this time, even if the second switch operation knob 9 can be operated, the first switch operation knob 8 cannot be operated.

In the modified embodiment shown in FIG. 5, the lock arm 17 is integrally formed to extend downward from the razor head 2, and the razor 671 is tilted back and forth.

The engaging/disengaging portion 17a attached to the lower end of the arm 17 or the operating rod 1
The recesses 18 and 19 formed on the left and right sides of the lower surface of the 0 are alternately engaged with and disengaged from each other. When scolded.

When the razor head part 2 is tilted forward, the engaging/disengaging part 17a of the first arm 17 is connected to the right end in the right recessed part 19. Can't you?

The first switch operation knob 8 can be operated by a button. The bushing operation movable amount of the first switch operating knob 8 is within the range until the right end in the right recessed part 19 comes into contact with the engaging/disengaging part 17a. On the other hand, when the razor head part 2 is tilted backwards, the engaging/disengaging part 17a of the lock arm 17 engages with the left end in the left recessed part 18, so in this case, push the second switch operation knob 9. Is it possible to cultivate trenches? 1)
The inch operation knob 8 cannot be operated by a bushing.

As explained above, according to the present invention, an electric shaver having -
In addition to the first switch operating knob 8 that opens and closes the energizing circuit to the load 5 of the second battery 7, a second switch operating knob 9 that opens and closes the energizing circuit to the load 5 of the second battery 7 is provided. The battery 7 can be operated separately using dedicated operation knobs 8 and 9. Therefore, three users can easily use the first battery 6 and the second battery 7 properly.

Drive of the first battery 6 and the second battery 7 (one common use of Kuwasaku 1)
This eliminates the erroneous operation of driving the second battery 7 when the second battery 6 should be driven, as is the case when using the Eisaku knob. 'iN power supply function can be fulfilled.In addition, since the drive operation of the second power supply/+!!7 is performed with the dedicated operation knob 9, there is a knob on the common masterpiece knob of the second battery 6 and the second battery. This has the advantage that the frequency of use of the double-edged knobs 8, 9 is reduced, and the durability of the double-edged knobs 8, 9 can be improved accordingly.

In particular, in this invention, the first switch operation knob 8 and the second switch operation knob 9 are disposed on different surfaces 1a and 1b of the main body case 1 corresponding to the direction in which the throat section 2 is tilted. There are 2 Ryoengaku knobs 8.
