Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Industrial Application Field) The present invention relates to an electric razor that cuts beards using a reciprocating inner cutter and an outer cutter that slides into contact with the inner cutter.

(Prior Art) A conventional electric shaver is shown in FIG. Reference numeral 1 denotes an outer cutter case which is removably provided on a main body (not shown), and an outer cutter 3 having a number of small holes 2 formed on its surface is removably attached.

Reference numeral 4 denotes an inner blade which is linked to a motor (not shown) provided within the main body via a drive member 5 to reciprocate (in the left and right directions in the figure).

This inner cutter body 4 has an inner cutter support member 6, and the inner cutters are supported so that a large number of inner cutters 7 sliding in contact with the inner side of the outer cutter 3 are parallel to each other.
They are connected by a material 6. and small hole 2 of outer blade 3
The hair that has gotten into the hair is cut off by an outer cutter 3 and an inner cutter 7 that reciprocates.

(Problems to be Solved by the Invention) The electric razor with the above configuration has a problem in that when cutting beard, sebum gets stuck on the inner blade and beard debris adheres thereon, reducing the cutting quality. . SUMMARY OF THE INVENTION An object of the present invention is to provide a reciprocating electric shaver which prevents beard debris from adhering to the inner blade and prevents the sharpness from deteriorating.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an inner cutter body having an inner cutter support member that supports a large number of inner cutters that reciprocate and slide on the inner surface of the outer cutter. In the inner cutter supporting member, hair dust removing bodies are respectively disposed between the inner cutters and the inner cutters so as to be movable along the reciprocating direction of the inner cutter supporting member.

(Function) To shave the beard, the inner cutter body having a large number of inner cutters is reciprocated, and the inner cutters and outer cutters cut the beard introduced into the small hole of the outer cutter. At this time, as the inner cutter moves back and forth, the hair removal body moves along the inner cutter support member, collides with the inner cutter, and then moves in the opposite direction along the inner cutter support member and separates. It hits the inner blade of the blade. This movement of the hair removal body is repeated while the inner blade is reciprocating. Therefore, when the whisker debris removing body hits the inner cutter, the inner cutter is vibrated by the whisker debris removing body, so that the whisker debris attached to the inner cutter is removed. Furthermore, when the whisker is cut, the whisker debris removed from the inner blade support member is moved by moving over the inner blade support member, so that the whisker debris attached to the inner blade support member is also removed. Incidentally, since vibration is applied to the whisker debris removing body due to impact with the inner blade, whisker debris is not deposited on the body.

(Example) An example of a reciprocating electric shaver according to the present invention will be described based on the drawings. Reference numeral 11 denotes an electric shaver body which houses a motor (not shown) as a drive source, and an outer cutter case 12 serving as an outer cutter body is removably fitted therein. The outer cutter case 12 removably holds an outer cutter 14 having a large number of small holes 13. Reference numeral 15 denotes an inner blade which is interlocked with the motor via a drive member 16, and the rotational motion by the motor is converted into a linear motion by the drive member 16 for reciprocating motion (in the left-right direction in FIG. 3). The inner cutter body 15 has a large number of inner cutters 17 arranged in parallel in the reciprocating direction.The inner cutters 17 are in sliding contact with the outer cutter 14 and supported by an inner cutter support member 18. End plates 19 are provided integrally with the inner cutter support member 18 at both ends in the reciprocating direction. A sliding contact portion with the outer cutter 14 is formed on the arcuate outer periphery of the inner cutter 17, and the inside of this sliding contact portion of the inner cutter 17 is the main cutting portion, and the inner cutter 17 actually cuts small holes when cutting beards. This is the part that the whiskers introduced in 13 come into contact with.

One of the inner cutter support members 18, 18a, is provided at the main cutting part, and this inner cutter support member 18a has an iron plate formed in a C shape larger than the diameter of the inner cutter support member 18a. A hair removal body 20 is loosely fitted and movable along the inner cutter support member 18a. Moreover, this beard waste removal body 2
The distance X that can be moved perpendicularly to the inner cutter support member 18a of 0, that is, the vertical direction in FIG. It is.

The operation of the electric shaver with the above configuration will be explained. To cut the beard, the motor is powered on and the outer blade 14 is brought into contact with the skin. Then, the beard is introduced through the small hole 13 of the outer cutter 14, and the beard is cut by the inner cutter 17 and the outer cutter 14, which reciprocate in conjunction with the motor. The beard scraps cut at this time are removed by the inner blade 17. However, since the beard debris remover 20 moves up and down at the same time as it moves along the inner blade support member 18a, it removes the beard debris attached to the inner blade support member 18a and further removes the beard debris. Due to the contact between the body 20 and the inner cutter 17, the beard debris removal body 20 comes into contact with the inner cutter 17, and by giving vibration to the inner cutter 17, the beard debris attached to the inner cutter 17 is removed and separated from the main body 11 and the outer cutter. It is stored in a beard waste reservoir formed between the blade cases 12. For beard scraps, use the inner blade 17. If it adheres to the inner blade support member 18a over time, it will become stuck and difficult to remove, but according to the present invention, the hair chips are removed at the same time as the hair is being cut, so it is possible to easily prevent the hair chips from adhering. .

Further, as described above, since the relationship of X<Y exists, even if the hair removal body 20 moves up and down while the motor is driving, it does not directly contact the outer cutter 14, and therefore does not damage the outer cutter I4. Since the inner cutter support members 18 other than 18a are not located in the main cutting part, hardly any hair chips adhere to them. In general, the part most often used when shaving is the top part of the inner cutter 17 in FIG. 1 among the main cutting parts, and this is where the beard debris mainly adheres. Since the beard debris removing body 20 comes into contact with the vicinity of this top portion, the beard debris can be removed effectively. Since the hair chips adhering to the inner cutter 17 are removed as described above, the area of the mixed layer removing body 20 that contacts the main cutting part is determined as shown in FIG. 4, for example.
If the size is increased as shown in FIG. 5, the mixed layer adhering to the inner cutter 17 can be removed more effectively. The material of the mixed layer removing body 20 may be plastic resin, rubber, or the like.

The mixed layer removing body 20 shown in FIG. 6 shows another embodiment, and has brush bristles 21 planted around the periphery.By configuring it in this way, the inner blade 17 can be rubbed to effectively remove the mixed layer. This can also lead to noise reduction. Alternatively, a connecting rod that does not directly support the inner cutter 17 may be provided on the inner cutter support member 18, and the mixed layer removing body 20 may be provided on this connecting rod.

〔Effect of the invention〕

As explained above, according to the reciprocating electric shaver of the present invention, the mixed layer that adheres to the inner blade due to the reciprocating movement of the inner blade can be easily removed, thereby preventing deterioration in sharpness. It is something that can be done. Further, the mixed layer removing body can be constructed simply by attaching it to the inner cutter support member, and the assembly is easy and the structure can be simplified.
