Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in an electric shaver in which a razor head having an inner shaving cutter and an outer cutter is tiltably attached to a main body case.

This type of electric shaver is convenient to use because the razor head can be easily brought into contact with the skin by tilting the razor head forward or backward from the neutral position with respect to the main body case. However, when using this method, in addition to tilting the razor head forward or backward, it is necessary to slide or push a switch knob located on a part of the outer surface of the main body case to turn on the power switch, which is cumbersome. was.

This invention focuses on this fact and attempts to provide an electric shaver that can simplify operability by allowing the power switch to operate in conjunction with tilting of the razor head. It is something.

The details will be explained below based on the drawings. The drawing illustrates an electric shaver according to this invention.
The main body case 1 of this device has a razor head portion 2 attached thereto which can be tilted forward and backward. The razor head 2 includes an outer shaving cutter 3 and a vibrating inner cutter 4 that slides on the inner surface of the outer cutter 3. The main body case 1 is equipped with a cutting blade 6 that can move in and out of the upper opening of the front wall 5, and a drive mechanism (not shown) for driving the inner cutter 4 and the cutting blade 6, and a power source for the drive mechanism. Built-in switch 7 for opening and closing, front wall 5 and side wall 8
A slide knob 9 for moving the sharpening blade 6 in and out is provided at the ridge corner where the edges intersect.

In the electric shaver having such a structure, this invention is characterized in that means for operating the power switch 7 in conjunction with the tilting operation of the razor head portion 2 is provided on the main body case 1 side.

That is, to explain one specific example of the means in FIG. 2, an E-shaped operating rod 10 is disposed horizontally above the power switch 7 in the main body case 1 when viewed from the side. It has front and rear elongated holes 11, 12 and a central elongated hole 13, into which the front and rear shafts 14, 15 and the central shaft 16 fixed to the main body case 1 side are loosely fitted, respectively. They shall support their freedom of movement.
Further, the operating rod 10 has switch opening/closing actuators 17, 17 projecting upwardly above the front and rear elongated holes 11, 12, and a pressing protrusion 18 projecting downwardly below the central elongated hole 13. Then, the operating rod 10 connects the pressing protrusion 18 to the actuator 1 of the power switch 7.
The actuator 10 is brought into contact with the top of the actuator 9, and the entire actuating rod 10 is pushed upward in a horizontal position by the spring action of the actuator 19 or a return spring (not shown). Under this push-up biased state, the front and rear switch opening/closing actuators 17, 17 of the operating rod 10 open into the front part 20 which slopes low toward the front of the upper wall of the main body case 1, and the rear part 21 which slopes low toward the rear, respectively. It projects upward from the holes 22, 22. Switch opening/closing actuator 17,
The front part 20 and the rear part 21 of the razor head part 2 projecting from the head part 17 are opposed to each other so that the front part 23 and the rear part 24 of the lower surface of the razor head part 2 alternately come into contact with and separate from each other when the razor head part 2 is tilted forward or backward. It's a positional relationship.

In such a case, as shown in FIGS. 2 and 3, the razor head 2 may be aligned with the axis Y of the main body case 1
When held in the upper neutral position, the razor head 2 has a front part 23 and a rear part 2 of this underside.
4 are in a state of floating away from the front part 20 and rear part 21 of the upper wall of the main body case 1, respectively, and the front and rear switch opening/closing actuators 17, 17 both protrude to turn off the power switch 7. Now, if you tilt the razor head 2 forward as shown in Figure 4,
The lower front portion 23 of the head portion 2 presses the front switch opening/closing actuator 17 into the hole 22, and the operating rod 10 is attached to the collar 1 of the rear switch opening/closing actuator 17.
7a is brought into contact with the inner surface of the upper wall rear part 21 of the main body case 1, and is pushed down into a forward tilted position under the guidance of the front and rear shafts 14, 15 and the central shaft 16, and the actuator 19 is pressed by the pressing protrusion 18. With this, the power switch 7 is turned on, and the electric shaver is ready for use.

In addition, the razor head 2 is moved from the neutral position to the fifth position.
When the head unit 2 is tilted backward as shown in the figure,
The rear portion 24 of the underside of the actuator 10 presses against the rear actuator 17, and the actuator rod 10 is pushed down into a rearward tilted position under the guidance of the front, rear and central shafts 14, 15 and 16 with the flange 17a of the front actuator 17 abutting against the inner surface of the front portion 20 of the upper wall of the main body case 1. As in the forward tilted position, the pressing protrusion 18 presses against the actuator 19, the power switch 7 is turned on and the actuator is ready for use.

When the razor head 2 is returned to the neutral position from the forward or backward tilted state, the entire operating rod 10 is pushed up to its original position by the spring action of the actuator 19 of the power switch 7 or by a separate return spring (not shown). ,
The front and rear actuators 17, 17 protrude from the front and rear parts 20, 21 to turn off the power switch 7.

After that, the cap 27 shown in FIG.
As shown in the figure, the cap 27 is fitted into the razor head 2 from above, and the front and rear lower ends 27a, 27b of the cap 27 are
The off state of the power switch 7 is maintained by keeping the razor head 2 in the neutral position by bringing the razor head 2 into contact with the front and rear walls 5, 28 of the main body case 1 and the front and rear walls 2a, 2b of the razor head 2, respectively. This prevents the power switch 7 from malfunctioning due to back and forth tilting of the razor head 2 when carried. Also,
As shown in the illustration, the front and rear lower ends 27a of the cap 27,
Elastic locking claws 29, 29 on each inner surface of 27b
When the cap 27 is fitted, the locking claws 29, 29 are locked to the front and rear portions 23, 24 of the lower surface of the razor head 2. This prevents the cap 27 from coming off unexpectedly and prevents the power source from being removed. Malfunction of the switch 7 can be prevented more reliably.

The cap 27 also has a hinge 3 at the top of one side of the storage case 30, as shown in FIG.
Even if the shaver head 2 is rotatably attached through the razor head 2, by placing it over the razor head 2, it is possible to prevent the head 2 from tilting back and forth unexpectedly and to prevent the power switch 7 from malfunctioning.

According to the above specific example, one operating rod 10 and one power switch 7 are sufficient, but the present invention is not limited to this. For example, as shown in FIG. 6, two left and right actuating rods 10, 10 are arranged above the power switch 7 so as to intersect in an X-shape, and the lower end of each actuating rod 10 is vertically swung around the shaft 25. The switch opening/closing actuator 17 at the upper end of each actuating rod 10 may be freely pivoted and protrude from the front and rear portions 20 and 21 of the upper wall. Further, as shown in FIG. 7, power switches 7, 7 are arranged close to each other on the inner surfaces of the front part 20 and rear part 21 of the upper wall of the main body case 1, and the plunger 26 or actuator of each switch 7 is connected to the front part of the upper wall. 20 and the rear portion 21, respectively. At this time, plunger 2
6 or actuator is switch opening/closing actuator 17
becomes.

The razor head 2 may be tilted only forward or backward from the neutral position.

As explained above, this idea is based on the main body case 1.
When the razor head 2 is in the neutral position, turn off the power switch 7 and turn off the razor head 2.
When the switch 7 is tilted, switch 7 is activated in conjunction with this tilting operation.
Since it is equipped with a switch opening/closing actuator 17 that turns on the razor head 2, the operating state can be obtained at the same time as the razor head 2 is tilted, and the conventional switch on/off operation can be omitted, making handling extremely simple. becomes. Further, by placing the razor head part 2 in a straight neutral position with respect to the main body case 1, a switch-off state is achieved, and there is no problem in storing the battery built-in electric shaver in the storage case after use.
