Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary electric shaver, and includes a razor body 1.
At the tip of the razor body 1, there is an outer cutter 2 and an inner cutter 3 which is driven to slide and rotate on the inner surface of the outer cutter 2 by a motor 8. In the electric shaver provided with a sink waste storage chamber 5, a sink waste discharge hole 7 is bored in the enclosure cylinder piece 4, and a rotary ring 16 is fitted on the outer periphery of the enclosure cylinder piece 4 so as to be freely rotatable in the circumferential direction. An outer hole 17 is bored in the rotary ring 16 to open and close the sink waste discharge hole 7 by rotating the rotary ring 16.
The present invention relates to an electric shaver characterized in that a switch 19 is built into the razor body 1 to turn the motor 8 on and off in response to the rotational operation of the electric shaver 6.

BACKGROUND OF THE INVENTION Conventionally, a brush or the like has been used to clean and remove sink debris accumulated in the sink debris storage chamber of an electric razor.

However, this has various inconveniences, such as requiring time and effort to clean the sink debris and requiring a special brush.

The present invention has been made in view of the above points, and it is possible to discharge sink debris by utilizing the rotation of the inner blade without using a brush, and moreover, it is possible to discharge sink debris by using the sink debris discharge port of the sink debris storage chamber. The object of the present invention is to provide an electric shaver in which the motor can be turned on and off using a rotating ring that opens and closes.

The present invention will be explained in detail below with reference to Examples.

Fig. 1 shows the external appearance of an electric shaver.The razor body 1 is formed by a grip part 1a at the base and a protrusion part 1b extending toward the front side of the tip part. 2
is installed.

By driving the inner cutter 3 in sliding contact with the inner surface of the outer cutter 2 by a motor 8 housed in the razor body 1, the outer cutter 2 and the inner cutter 3 perform shaving.

In the figure, 10 is a trimmer.

Figure 2 is an enlarged cross-sectional view of the main parts, showing the output shaft 1 of the motor 8.
A rotating shaft 12 is attached to the razor body 1, and the inner cutter 3 is rotatably driven by this rotating shaft 12. Furthermore, a blade mount 13 is attached to the tip surface of the protrusion 1b of the razor body 1, and the blade mount 13 is The outer cutter 2 is attached by screwing the ν base of the outer cutter 2 into a threaded portion 14 provided on the inner periphery of the surrounding cylinder piece 4.

A sink waste storage chamber 5 is provided in the blade mounting base 13 on the inner circumference of the enclosure cylinder piece 4.
The sink debris scraped by the outer cutter 2 and the inner cutter 3 is stored in the sink debris storage chamber 5.

Further, a partition wall 6 extends radially from the central cylinder 1 portion 15 surrounding the rotating shaft 2 at the bottom of the sink waste storage chamber 5, and this partition wall 6
The waste storage room 5 is partitioned off.

Furthermore, a sink waste discharge hole 7 is bored in the enclosure cylinder piece 4 at the tip of the partition wall 6 as shown in FIG.

Reference numeral 16 denotes a rotating ring, which is attached to the outer periphery of the enclosing cylinder piece 4 of the blade mount 13 so as to be rotatable in the circumferential direction.
is perforated.

The rotating ring 16 is held on the outer periphery of the surrounding cylinder piece 4 by the locking flange piece 18 of the surrounding cylinder piece 4, and by turning the rotating ring 16 and aligning the outer hole 17 with the sink waste discharge hole I. The sink debris discharge hole 7 is opened outward, and the sink debris discharge hole 7 and the outer hole 17 are disengaged from each other, thereby closing the outward opening of the sink debris discharge hole I.

20 is a waterproof 01J ring.

Further, the switch 19 is composed of a pair of reed switches 21 and 22 and a pair of magnets 23 and 24, and the pair of reed switches 21 and 22 are extended to a battery cover 25 installed inside the razor body 1 as shown in FIG. Installed mounting stand 26
The reed switches 21 and 2 are installed on different levels under the ground.
Terminals 27 of 2 are connected to a current-carrying metal fitting 28, and connected to a motor 8 and a battery installed in the razor body 1 through a wiring circuit as shown in FIG.

The magnets 23 and 24 are mounted on a mounting plate 29 extending from the rotating ring 16 by being buried therein.
3 is attached to one reed switch 21, and the other magnet 24 is attached at a position corresponding to the other reed switch 22 in two stages, upper and lower.

When shaving with the electric shaver formed as described above, the sink waste discharge hole 7 is closed with the rotary ring 16.

That is, in FIG. 5a, the magnet 23 does not correspond to the center of the reed switch 21 and the motor 8 is not driven to rotate.
When the rotating ring 16 is turned in the direction of the arrow as shown in FIG. In this way, the inner cutter 3 is rotationally driven to perform shaving.

The operation shown in FIG. 5 ayb is repeated to determine whether or not to use it when shaving.

Furthermore, when shaving, the rotation of the inner blade 3 causes the sink debris to be sent inside with the flow of wind, and the sink debris is sent to the sink debris storage chamber 5.
It is stored in

At this time, since the partition wall 6 is provided upright in the sink debris storage chamber 5, the sink debris is prevented from scattering by the partition wall 6.

Next, when discharging sink debris from the sink debris storage chamber 5, turn the rotary ring 16 to connect the sink debris discharge hole 7 to the outer hole 17.
to open the sink waste discharge hole 7.

To explain this operation, first, as shown in Figure 5C,
Turn the rotary ring 16 one more step from the state shown in the figure to open the sink waste discharge hole 7.

At this time, the magnets 23 and 24 do not correspond to the central parts of the reed switches 21 and 220, the switch 19 is in the off state, the motor 8 is not driven, and even if the beard waste discharge hole 7 is opened, the inner blade 3 There is no risk of the sink rotating and scattering debris.

In this state, the outer cutter 2 is immersed in water, and the rotating ring 16 is further rotated one step as shown in FIG. 5d.

Then, the magnet 24 is placed in the center of the reed switch 22, the reed switch 22 is turned on, the switch 19 is turned on, and the motor 8 is activated to rotate the inner cutter 3.

When the inner cutter 3 rotates with the sinkage waste discharge hole 7 open in this way, water is sucked in as the inner cutter 3 rotates, and the inside of the sinkage waste storage chamber 5 is washed with water, and the sinkage waste is removed by water. It is washed away and discharged from the sink debris discharge hole 7.

By cleaning the sink debris in this way, you do not need a brush or the like, and you can also remove the outer blade 2 and inner blade 3 from the razor body.
This means that you can clean it without having to remove it.

As described above, in the present invention, the motor can be turned on and off by using the rotational operation of the rotary ring that opens and closes the sink waste discharge hole, and there is no need to provide a separate switch button. Since the opening/closing of the sink debris discharge hole and the on/off of the switch can be linked, there is no risk of sink debris scattering from the sink debris discharge hole due to a mistake in opening/closing the sink debris discharge hole or turning on/off the switch. It is.
