Description

[Detailed description of the invention] This invention relates to a water-washable electric shaver that uses the rotation of the inner blade to stir water that has flowed into the inner blade storage chamber through the outer blade, thereby washing away the hair that has accumulated in the inner blade storage chamber. To improve the opening/closing lid that freely opens and closes the discharge port formed on the outer circumferential side wall of the blade storage chamber, so that the lid can be opened and closed with a small stroke, and hair debris does not fall out from the discharge port. With the goal.

In other words, in this type of water-washable electric shaver,
Conventionally, the discharge port formed on the outer peripheral side wall of the inner blade storage chamber was opened and closed by a lid that slid along the outer peripheral side wall.

However, when the lid slides, it is necessary to form rails and guide grooves on the razor head to guide the lid along the outer circumferential wall, which complicates the structure and increases the molding time. Hairs and the like tend to form, and when the lid is closed, there is a risk that hair will fall out from the small gap between the outlet and the lid caused by such hairs or other molding errors.

Further, hair particles get caught in the sliding surface of the lid, obstructing the sliding operation, which is also unhygienic.

This invention focuses on this fact, and when covering the discharge port formed on the outer peripheral side wall of the inner blade storage chamber, it not only covers only the discharge port so that it can be opened and closed, but also covers the bottom wall corresponding to the discharge port. The above-mentioned drawbacks have been solved by covering the receiver from below in a dish-like manner.

Hereinafter, a specific example thereof will be explained based on the drawings.

In FIG. 1, reference numeral 1 denotes a razor body with a built-in motor, and a razor blade block 2 is connected to the upper end of the razor body in a replaceable manner.

The sled blade block 2 has a circular outer peripheral side wall 3 when viewed in cross section.
A holder 6 that supports the inner cutter 5 is housed in the inner cutter accommodating chamber 4, and this inner cutter holder 6 is connected to a vertical drive shaft 7 to drive the inner cutter. The blade 5 rotates.

A holder 10 of the outer cutter 9 is screwed onto the outer periphery of the outer peripheral side wall 3 from above, and the outer cutter 9 comes into sliding contact with the inner cutter 5.

A discharge port 11 is provided at one location on the outer circumference side wall 3, and the water flowing into the inner cutter storage chamber 4 through the outer cutter flows along the inner surface of the outer circumference side wall 3 due to the rotation of the inner cutter 5, and the hair waste in the storage chamber is removed. The basic structure is such that the water flows out from the discharge port 11 which is opened at the same time.

Note that 14 is a removable cap that covers the outer periphery of the outer cutter 9.

Here, the discharge port 11 is covered by an opening/closing lid 13 whose rear end is swingably supported in the vertical direction on the bottom wall 12 of the inner blade storage chamber 4 so as to be openable and closable.

As shown in FIG.
3a and a lid piece 13b that is continuously formed upright from the front end of the bottom wall covering piece 13a, and is located on the lower surface of the bottom wall corresponding to the discharge port 11 and from the outer surface of the outer peripheral side wall 3. By pivoting the rear end of the opening/closing lid 13 on the inner diameter side, the bottom wall covering piece 13a can be opened in the closed state.
covers the bottom wall corresponding to the discharge port 11 from below in a close state, and at the same time covers the discharge port 11 with the lid piece 13b.

In addition, a cylindrical post 15 is installed in the center of the bottom wall 12 of the inner blade storage chamber 4.
is erected, and the drive shaft 7 is passed through the boss 15 via an oilless metal 16.

It is assumed that the inner bottom surface 12a of the inner blade storage chamber 4 is formed into a mortar shape having a deep annular water reservoir 17 around a central boss.

Furthermore, a rectifying plate 19 is disposed in the circumferential middle of the discharge port 11 and extends radially.
It is designed to slightly protrude inward from the inner surface 3a of the.

Therefore, when washing with water, move the opening/closing lid 13 to open the discharge port 11, and rotate the inner cutter 5' while pouring water into the inner cutter storage chamber 4 through the outer cutter 9. The water will flow to the center of the inner bottom surface 12a. The water accumulated in the puddle 17 is circulated and gathered toward the outer circumference, and as shown in FIG.
Flows along the inner surface 3a as shown by the arrow a, and the discharge port 11
This corresponds to the current plate 19.

As a result, the flow of water is regulated from the direction of the arrow a to the radial direction, and at the same time the flow velocity is reduced and the water is smoothly discharged from the discharge port 11 without splashing around.

Furthermore, when the opening/closing lid 13 is closed, that is, during normal use, the lid piece 13b constituting the opening/closing lid 13 closes the discharge port 1, as described above.
In addition to directly covering the outlet 11, the bottom wall 12 corresponding to the outlet 11 is protected from below by the bottom wall covering piece 13a in a dish-like manner. 1
It is designed to reliably catch the hair that falls from the small gap between the hair and the hair 3b.

Further, since the opening/closing lid 13 is opened/closed by swinging up and down using its rear end as a fulcrum, the stroke required for opening/closing can be small.

The outer peripheral side wall 3 of the inner cutter housing chamber 4 is preferably perfectly circular in cross-sectional view, but may be oval.

As explained above, this invention is a water-washable electric shaver equipped with a rotary inner cutter 5, in which a hair waste outlet 11 is opened in a part of the outer peripheral side wall 3 of the inner cutter storage chamber 4, and the hair waste outlet 11
An opening/closing lid 13 consisting of a bottom wall covering piece 13a and a lid piece 13b formed continuously upright from the front end of the bottom wall covering piece 13a on the lower surface of the bottom wall corresponding to and on the inner diameter side of the outer surface of the outer peripheral side wall 3. The rear end is pivoted so that it can be opened and closed in the vertical direction, and in the closed state, the bottom wall cover piece 13a covers the bottom wall corresponding to the discharge port 11 from below in close proximity, and at the same time, the cover piece 13a closes the bottom wall corresponding to the discharge port 11. It is designed to cover exit 11,
To provide a water-washable electric shaver that has a small opening/closing stroke of a lid and can reliably prevent hair waste from spilling out from an outlet when the lid is closed.
