Conventionally, electric razors have an inner cutter that is fixed to a drive shaft and comes into contact with the inner cutter, covering the entire inner cutter, regardless of the drive method, for example, whether the inner cutter is rotated or vibrates back and forth. Most of them consist of an outer blade fixed to the main body, and the inner blade is driven to cut the hair that is introduced through the hole or groove provided in the outer blade. Beard debris collects inside the outer blade. However, in this case, when cleaning the beard debris, the outer blade is removed from the main body, leaving the inner blade on the main body side, so if the switch is turned on in that state, the inner blade will not be activated. There is a risk of danger such as cutting your fingers. In particular, rotary drive razors are preferred because of their portability and low vibration and noise, but compared to reciprocating and vibrating razors, the inner blades rotate at a higher speed. The risks mentioned above are much greater.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional electric shaver, and its operation is performed when the outer blade is removed from the electric shaver body for hair removal, cleaning, blade inspection, and blade replacement. Then switch the inner blade drive motor or electromagnetic vibrator.
Even if it is turned on, it will not drive, and will only operate when the outer blade is securely fixed to the electric shaver body.

Next, a detailed explanation of the present invention will be given based on examples. FIGS. 1a and 1b are perspective views of an electric shaver embodying the present invention, in which an inner cutter 2 fitted with a drive force transmission shaft from the electric motor is provided in the upper opening of an electric shaver main body 1 containing a built-in electric motor. A groove 5 is provided around the lower part of the outer cutter frame 4 that holds the net-like outer cutter 3 that is inscribed in the inner cutter 2, and an elastic member that fits into the groove 5 and locks the outer cutter frame is provided. It is composed of a pair of opening/closing tools 6 having the following functions. Note that the perspective view shown in FIG.
Fig. 1 b
An opening/closing tool 6 is provided inside the upper opening 7 of the electric shaver main body 1 in which the inner cutter is disposed, and is adapted to fit and lock into the groove 5 surrounding the lower inner circumference of the outer cutter frame 4. In both cases, the outer surface of the main body 1 is equipped with an electric motor drive.
It has a switch 8 that controls ON and OFF.
As shown in the figure, when the outer cutter frame 4 is removed, the electric motor will not be driven even if the switch 8 is turned on, and therefore the inner cutter 2 fitted to the drive force transmission shaft from the electric motor will also be driven. Not done. Therefore, the inner blade is driven when cleaning and disposing of the beard debris that has collected inside the upper opening 7 of the main body 1, when the blade is in a dangerous condition, or when the blade is to be replaced after a certain period of use. There is no risk of cutting your fingers due to the risk of injury. That is, in order to provide such a safety mechanism, the present invention aims to provide the groove 5 that fits the opening/closing tool of the outer cutter frame 4 shown in FIG.
The entire part is made of a conductive material such as aluminum or copper alloy, and a part of the power supply line for driving the conductive machine, for example, a power supply line in series with switch 8, is connected to the opening/closing tool, and the outer cutter frame is connected to the switch 8. The power supply line is closed by the conductive member of the outer cutter frame only when it is fitted into the opening/closing tool, and the electric motor can be driven.
Since the above description is an overview of the present invention, the internal structure of an embodiment of the present invention will be described in detail below.

電動機は駆動せず内刃も駆動しないものである。 In Figure 2, as in Figure 1, 1 is the electric shaver body, 2 is the inner cutter, 3 is the outer cutter, 4 is the outer cutter frame holding the outer cutter 3, and 5 is the inner circumference of the lower part of the outer cutter frame. Groove provided,
Reference numeral 6 denotes an opening/closing tool for locking the outer cutter frame 4 to the main body 1 by fitting into a groove 5 provided around the lower inner circumference of the outer cutter frame 4. Further, an electric motor 9 is disposed inside the main body 1, and the drive shaft of this motor extends outside from the upper opening of the main body, and transmits its driving force to the inner cutter 2 through a driving force transmission shaft 10. Input terminals 11 and 12 are arranged at the bottom of this motor, and input terminal 11 has a battery 13.
Connect the poles of the power source from the battery 13 to the input terminal 12.
is configured to connect the poles of the power supply from the However, as is clear from Figure 2, battery 1
The pole No. 3 is not directly connected to the pole terminal 11 of the motor 9, but follows the following path. That is, a battery spring 14 made of an elastic copper alloy, such as phosphor bronze for springs, which also serves to hold the battery 13, is in contact with the battery pole, and this spring 14 is made of a conductive material, such as aluminum whose exterior is anodized. It is in contact with the battery case 15 constructed by the above. This battery case 15 is fixed by screwing with a screw provided on the outer periphery of the lower part of the main body 1, and further comes into contact with a switch contact A16, which is a component of a switch configured inside the main body. This switch contact A
16 is a switch contact short circuit piece 18 fixed to a switch button 17 protruding from the outer circumferential surface of the main body 1, and a switch contact B is connected when the switch is ON.
Connected to 19. The switch contact B19 contacts the switch 6 via a switch spring 20 made of an elastic conductor such as phosphor bronze for a spring, piano wire, etc., and the switch 6 made of aluminum or the like is made of a conductive material such as aluminum. It fits into a groove 5 provided in a part or all of the outer cutter frame, which is connected via another switch spring 20 to a pole terminal on the bottom of the motor. As can be seen from the above-described connection path of the poles, when the outer cutter frame or the power supply line is open, the motor does not drive and the inner cutter does not drive either.

As mentioned above, the present invention has a simple structure and does not require the addition of any particularly large parts, and the outer cutter frame is made of a conductive material instead of the conventional outer cutter frame opening/closing tool, and the outer cutter frame is made of a metal such as aluminum instead of the conventional material. This is an electric shaver with a safety mechanism that allows you to safely clean beard debris, inspect the blades, and replace the blades without worrying that the inner blades that remain in the main body will never rotate even when the switch is turned on when the outer blades are removed. It is possible to provide the following. Note that the explanation based on the embodiment described above is an example based on the present invention, and a wide range of applications can be considered without being limited to the scope of this embodiment.
