Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to an electric shaver, and particularly to a waterproof electric shaver that can be washed with water.

[Background technology]

Waterproof electric razors are equipped with an outlet that communicates with the beard debris storage chamber so that the beard debris that accumulates inside can be flushed away when washing with water, and an outlet that communicates with the beard debris chamber to prevent the beard debris from scattering during normal use. It has a door that opens and closes. In order to facilitate the operation of opening and closing the door, a ring is provided around the outer circumference of the body of the electric shaver, and by providing the above-mentioned door on this ring, the door can be opened and closed by turning the ring with the finger that grips the body. We provide what you can do. Here, the rotation plane of the ring in a conventional electric shaver of this type is perpendicular to the axial direction of the electric shaver body, but the trajectory of the finger when rotating the ring by moving the finger gripping the body. Since is not perpendicular to the axial direction of the main body,
The problem is that it is difficult to rotate the ring.

[Purpose of the invention]

The present invention has been made in view of these points, and its object is to provide an electric shaver in which the outlet door can be easily opened and closed using the fingers gripping the main body.

[Disclosure of the invention]

Therefore, the present invention has a cylindrical main body equipped with a beard waste storage chamber and a discharge port communicating with the beard waste storage chamber, and a door for opening and closing the discharge port, which is rotatably disposed on the outer surface of the main body. In an electric shaver equipped with a ring,
A ring mounting part on which a ring with an inner diameter of a perfect circle is rotatably mounted is formed obliquely on the outer surface of the main body, and the rotating surface of the ring is inclined with respect to the axial direction of the main body. A feature is that a finger hook is provided on the outer surface of the ring at a position approximately midway between the ring and the lower end, so that the operating direction of the ring follows the trajectory of the finger gripping the main body. This is what I did. The present invention will be described in detail below based on illustrated embodiments. This electric shaver is of a rotary type, and
The main body 1 with the outer cutter 7 disposed at its upper end includes a blade frame 11 holding the outer cutter 7, a cylindrical main body housing 10 in which a motor 15 is disposed, and an upper end of the main body housing 10. An auxiliary housing 12 located between the blade frame 11, a cylindrical base 14 disposed inside the main body housing 10 and whose lower end protrudes from the lower opening of the main housing 10, and a lower end opening of the base 14. The battery cover 13 closes the battery cover 13, and the inside of the lower part is a battery storage chamber. In the figure, 16 is a protective case for protecting the outer cutter 7, and 5 is a switch handle. The inner cutter of the inner cutter block attached to the output shaft of the motor 15 comes into sliding contact with the inner surface of the outer cutter 7 to shave the beard. The main body 1 of this electric shaver is formed so that the cross section perpendicular to the axial direction thereof is a perfect circle.
The main body housing 10 has a shape in which the upper and lower ends are respectively cut diagonally, and the base 14 is fixed within the main body housing 10 by locking the hooks 17 to the inner surface of the main body housing 10. The battery cover 13 is attached to the base 14 by being screwed to the outer peripheral surface of the lower end of the base 14. At this time, the O-ring 18 disposed on the outer peripheral surface of the base 14 and compressed between the base 14 and the battery cover 13 comes into contact with the inner peripheral surface of the lower end of the main body housing 10. The lower part of the main body 1 is waterproofed. The upper part of the main body 1 is waterproofed by a packing 19 through which the output shaft of the motor 15 is inserted. The beard waste storage chamber 3 is surrounded by an auxiliary housing 12, and the main body 1 is supplied through an outlet 30 formed by cutting out a part of the outer peripheral wall of the auxiliary housing 12. It is said to be able to communicate freely with the outside world. The door 20 for opening and closing the discharge port 30 is formed so as to protrude integrally from a ring 2 attached to the outer surface of the main body 1 along the diagonally cut edge of the upper end of the main body housing 10. By rotating the door 20, the auxiliary housing 1
2 to open and close the discharge port 30. Here, since the main body 1 has a perfect circular cross section perpendicular to its axial direction, the ring 2 has an outer shape as shown in FIGS. 8 and 9.
By forming the ring 2 into an elliptical shape with a long axis L and a short axis S, the outer shape of the ring 2 becomes a perfect circle with a diameter D as shown in FIG. 2 when the ring 2 is viewed from the axial direction of the main body 1. I am trying to make it so that And this ring 2
In order to rotate the ring 2, the inner diameter of the ring 2 is a perfect circle with a diameter d, and the main body housing 1 of the main body 1 is
The ring mounting portion formed along the upper edge of the ring 2 is also a perfect circle, and the rotating surface of the ring 2 is inclined at an angle θ with respect to the axial direction of the main body 1. In the figure, 21 is a finger rest provided on the outer peripheral surface of the ring 2, and 22 is a projection for regulating the rotation range of the ring 2 and receiving a click. In this electric razor, when washing out the beard debris accumulated in the beard debris storage chamber 3 with water, as shown in FIG. The ring 2 is rotated to open the door 20, and in this state, water is allowed to flow into the beard waste storage chamber 3 through the outer cutter 7 and discharged from the discharge port 30. As is clear from the figure, the movement of the finger when turning the ring 2 coincides with the direction of rotation of the ring 2, which is attached diagonally to the main body 1. It can be easily operated without changing the grip or the like. The lower edge of the main body housing 10 is also cut diagonally in order to highlight the design feature of this electric shaver, in which the ring 2 is arranged diagonally.As shown in FIG. The lower edge of the main body housing 10 also serves as a grip for fingers when gripping the main body 1, and has a non-slip function, so that it can be held securely.

【Effect of the invention】

As described above, in the present invention, the ring mounting part on which the ring with the inner shape of a perfect circle is rotatably mounted is formed obliquely on the outer surface of the main body, so that the rotating surface of the ring is tilted with respect to the axial direction of the main body. A finger rest part was provided on the outer surface of the ring at a position approximately midway between the upper and lower ends of the ring attachment part, so that the finger rest part, on which the finger rests when rotating the ring, is aligned with the axis of the main body of the ring. It is formed at the part that intersects diagonally with the ring, and when you put your finger on the finger rest and turn the ring, you have to rotate the finger rest so that it moves diagonally upward, and the finger that grips the main body When turning the ring, the movement of the finger matches the direction of rotation of the ring, and the ring can be easily rotated without changing the grip on the main body. Although the rotating surface is oblique with respect to the axial direction, the inner shape of the ring is a perfect circle, so the ring itself rotates smoothly.
