Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electric shaver that can discharge beard shavings to the outside without removing the outer cutter body.

[Technical background of the invention]

As a prior art, a reciprocating electric shaver is known in which an opening/closing lid is provided on each of the left and right end walls of an outer blade attached to a main body case, and the opening/closing lid is biased by a metal spring. There is.

[Problems with background technology]

For this reason, there is a problem that the number of parts is large and the structure and assembly are complicated, and the closing force of the opening/closing lid cannot be maintained for a long period of time due to rusting of the springs and the like.

[Purpose of invention]

Therefore, an object of the present invention is to provide an electric shaver that can eliminate the various problems of the prior art described above.

[Summary of the idea]

The electric shaver according to the present invention has a body case that includes:
A space is formed between the main case and the case to accommodate the inner blade body, and the outer blade body is removably attached thereto, and a discharge port communicating with the space is provided at the rear of the outer blade body in the main body case, and The outlet cover for opening and closing the outlet is rotatably attached to the outer surface of the main body case.
Further, a lid operating body made of an elastically deformable resin material and configured to rotate the discharge port cover is reciprocally attached to the outer surface of the main body case, and the lid operating body uses its own elastic force to discharge the discharge port. It is characterized by being integrally equipped with an arm portion that constantly biases the roof of the mouth.

According to this electric shaver, since the discharge port lid is always closed by the biasing force, the discharge port can be reliably closed and the discharge of beard shavings during use can be reliably prevented. The ejection port cover is biased by the elastic force of the arm of the resin lid operating body, and unlike the prior art, metal springs are not used, reducing the number of parts and simplifying the structure and assembly. In addition, since there is no rust in the biasing member, the closing force of the outlet cover can be maintained for a long period of time.

[Example of idea]

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 8.

In the figure, reference numeral 1 denotes a main body case made of resin, which includes a front case 2 and a rear case 3, for example. A locking portion 4 protrudes from the upper front surface of the case 1, and a locking clamp convex portion 5 is provided. The locking clamp convex portion 5 is elastically deformable and has an operating portion 6 that protrudes outside the main body case 1 . The outer blade body 7 is attached to the main body case 1 by being removably engaged with the locking portion 4 and the locking clamp 5.

The main body case 1 includes a motor 8, an inner cutter reciprocating drive mechanism 9 operated by this motor 8, and this mechanism 9.
A reciprocating inner cutter body 10 supported by the inner cutter body 10 and slidingly in contact with the inner surface of the blade plate of the outer cutter body 7, and a battery (not shown) are built-in. Note that 11 is a PC board, 12 is a seal packing, and 13 is a rubber drive mechanism seal.

A cavity 14 is formed between the main body case 1 and the outer blade 7 to accommodate the inner blade 10. The bottom surface of this space 14 is inclined rearward toward the upper surface of the main body case 1, for example. Further, a shavings reservoir 15 is formed in the main body case 1 in communication with the lowest position of the bottom surface of the cavity 14. The opening on the side opposite to the opening on the space 14 side of this hair scraps reservoir 15 serves as a discharge port 16 and is opened on the upper surface of the main body case 1 at the rear of the outer cutter body 7. In addition, 17 in the figure is an introduction guide surface to the beard debris reservoir 15.

The discharge port 16 is opened and closed by a hard resin discharge port cover 18 provided on the outer surface of the main body case 1. The mounting portion 19 of the outlet cover 18 has a pair of slits 20 and a shaft 21, and the cover 18 is rotatably mounted by fitting the shaft 21 into a bearing hole 22 provided on the outer surface of the main body case 1. The discharge port 16 is opened and closed by its rotation. Note that the slit 20 is attached to the mounting portion 19.
This makes it possible to elastically deform the discharge port cover 18 and facilitate attachment and detachment of the discharge port cover 18 to the main body case 1. and,
The attachment portion 19 is integrally provided with, for example, a protruding engagement portion 23 . Furthermore, an operating body guide 24 consisting of a pair of opposing long grooves is provided on the outer surface of the main body case 1, and a lid operating body 25 is attached to the guide 24 to be guided in a reciprocating manner. The lid operating body 25 is made of an elastically deformable resin material, and integrally includes an arm portion 27 having an engaging claw 26 at the tip, and a thin wall on the side opposite to the protruding side of the arm portion 27. A buffer section 28 is integrally provided. In addition, 29
is an escape groove for allowing the buffer portion 28 to deform.
The arm portion 27 is elastically deformable, and its engaging claw 26 is engaged with the engaging portion 23 to constantly urge the discharge port cover 18. Note that 29 is a recessed groove provided on the outer surface of the main body case 1, and has a stopper surface 30 on which the buffer portion 28 approaches and separates.

This electric shaver is in the state shown in FIG. 1 when in use and when not in use, and the outlet 16 is pushed from the outside by the elasticity of the arm 27 of the lid operating body 25 to be discharged. The outlet 16 is reliably closed. Therefore, the beard debris in the beard debris reservoir 15 can be prevented from leaking out from the discharge port 16.

Then, to clean the blade etc. by washing with water, for example,
First, the discharge port cover 18 is opened by moving the cover operating body 25 in the direction of arrow A in FIG. In this case, as shown in FIGS. 6 to 8, the arm portion 27 further elastically deforms and moves the discharge port cover 18 approximately 90 degrees around the shaft 21 through the engagement between the engaging claw 26 and the engaging portion 23. Rotate it once to open the discharge port 16. In this lid opening operation, since the moving direction of the lid operating body 25 and the opening direction of the discharge port lid 18 are the same, there are fewer mistakes in the operation. The open state of the lid 18 is shown in FIG. In this open state, the arm portion 27 serves as a stopper, so that rotation of the discharge port cover 18 is reliably prevented even if a small amount of force is applied. During this lid opening operation, as the engaging claw 26 crosses the line B--B in the figure due to the elastic deformation of the arm 27 shown in FIGS. 2 to 8, the arm 27 quickly returns to its original position. You can feel a sense of motion. Furthermore, the lid operating body 25 is moved by the concave groove 18 and the stopper surface 3 due to the articulated movement during the lid opening operation.
However, since this contact is made via the buffer portion 28, the shock at the time of the contact can be softened without using a special buffer material. After that, water is poured from the direction of the second middle arrow C. Then, the water passes through the blade plate of the outer blade body 7, flows along the surface of the inner blade of the inner blade body 10, flows along the bottom surface of the cavity 14, and flows into the shavings reservoir 15, and then flows through the discharge port 16.
It flows out along with beard debris. Furthermore, the drained water is received by the discharge port cover 18 as shown by the arrow D in FIG. will be guided to. By washing with water as described above, the outer blade body 7, the inner blade body 10, and the space 14 can be cleaned. Further, after washing with water, the discharge port 16 may be closed by pushing up the lid operating body 25 and rotating the discharge port cover 18, and in this case as well, the elastic deformation of the arm portion 27 provides a sense of motion.

Note that although the above embodiment is configured as described above,
The present invention can also be applied to electric shavers that cannot be washed with water and rotary electric shavers. others,
In carrying out the present invention, unless it is contrary to the gist of the invention, specific structures such as the main body case, outer blade body, cavity, inner blade body, discharge port, discharge port cover, lid operating body, arm portion, etc. Of course, the shape, position, material, etc. are not limited to the one embodiment described above, and can be configured and implemented in various ways.

[Effect of idea]

Since the present invention described above has the structure described in the above-mentioned utility model registration claim, the arm part of the lid operating body also serves as the spring for biasing the discharge port lid, and no special spring is required. Compared to the prior art, the number of parts is reduced, simplifying the structure and assembly, and since no metal springs are used, it is possible to prevent the closing force of the outlet cover from decreasing due to rust, etc.
It is possible to keep beard debris from leaking from the ejection palate for a long period of time.
