Description

  The present invention relates to an electric shaver which is suitable for removing hair chips, sebum and the like adhering to an inner blade.

  A rotary electric razor has an outer blade formed by bending a thin metal plate with a large number of scissors-introducing holes bent into a curved shape, and a plurality of cutter blades held by the inner blade are pressed against the inner surface of the outer blade by a spring. Has been. The rotary electric razor shaves by rotating the inner blade by a motor (not shown) built in the main body case and rotating the cutter blade in sliding contact with the inner surface of the outer blade.

  By the way, in the rotary electric razor having the above-described configuration, the crest and trough are formed by the cutter blade of the inner blade formed in a spiral shape. In particular, in the valley portion, the hair chips and sebum accumulate. In particular, if hair chips, sebum, or the like accumulates in the valleys formed by the cutter blade, the sharpness of the rotary electric razor is remarkably lowered, and the hygiene is adversely affected.

  For this reason, the electric razor which can remove the shavings, sebum, etc. which have adhered to the inner blade is proposed conventionally.

For example, a cleaning tool in which a brush for cleaning an inner blade is arranged on the inner surface of a cap that is replaced with an outer blade holder has been proposed (see, for example, Patent Documents 1 and 2). However, such a cleaning tool described in Patent Documents 1 and 2 must be discontinued each time cleaning is performed, and the outer blade holder and cap must be replaced, which is excessive for the user. It was supposed to force the burden.

  Accordingly, the present invention has been devised in view of the above-mentioned problems, and the object of the present invention is to automatically clean off the shavings and sebum adhering to the inner blade each time the electric razor is used up. An object of the present invention is to provide an electric shaver capable of maintaining the sharpness over a long period of time by omitting the removal work and making it possible to always remove them even during actual use of the electric shaver.

  In order to solve the above-described problems, an electric razor according to the present invention is an electric razor having a blade head portion and a grip portion connected to a lower portion of the blade head portion for gripping by a user. Is an outer blade formed by bending a metal thin plate having a large number of rivet introduction holes bent into a curved shape, an inner blade formed in a spiral shape and slidably contacting the inner surface of the outer blade, and at least the tip Includes a brush body circumscribing the bottom of the valley portion of the inner blade, and a motor for rotating the inner blade based on a user-designated operation is mounted in the grip portion, and is rotated by the motor. The brush body removes at least the shavings and sebum adhering to the valleys of the driven inner blade.

  With the electric shaver to which the present invention is applied, it is possible to always remove freckle, sebum and the like even during actual use, and in particular, to prevent the accumulation of fouling and sebum in the valley portion of the cutter blade. Can do. For this reason, in the electric shaver to which the present invention is applied, the sharpness can be constantly improved, and an excellent structure can be obtained in terms of hygiene. Further, in the present invention, since the inner blade can be cleaned simultaneously with the use of the electric razor, the use is not stopped every time the cleaning is performed, and further, the user's work burden associated with the cleaning can be reduced. It is also useful in terms.

  Hereinafter, as the best mode for carrying out the present invention, an electric razor that removes shavings and sebum adhering to an inner blade even during actual use will be described in detail with reference to the drawings.

  An electric razor 1 to which the present invention is applied has, for example, as shown in FIG. 1, a blade head portion 3 and a grip portion 4 that is connected to the lower portion of the blade head portion 3 and is gripped by a user. The grip portion 4 is formed with at least a switch button 2 for the user to operate the electric razor 1. Incidentally, a motor (not shown) is mounted in the grip portion 4, and the motor rotates based on the pressing input of the switch button 2.

  FIG. 2 is an exploded perspective view of the blade head portion 3. The blade head part 3 is roughly divided and includes an outer blade 11, an inner blade 12, and a brush body 13. Incidentally, FIG. 3 shows a cross-sectional configuration diagram of the blade head portion 3.

  The outer blade 11 is mounted on the outer blade holder 21. The outer blade 11 is configured by bending a thin metal plate having a large number of punch introduction holes into a curved shape.

  The inner blade 12 is formed by spirally forming a cutter blade. In other words, the inner blade 12 has a crest and a trough formed by the spirally formed cutter blade. Two inner blades 12 are arranged so as to be rotatable in the inner blade holder 22. The inner blade 12 is fixed so as to be in sliding contact with the inner surface of the outer blade 11 as shown in FIG. The inner blade 12 is rotationally driven by the motor (not shown).

  The brush body 13 is fixed to the brush holder 23. The brush holders 23 are fixed in two rows so that the brush bodies 13 can be circumscribed with respect to each of the two inner blades 12. The brush holder 23 may be provided with a mechanism that is detachable from the inner blade holder 22. That is, by making the brush body 13 detachable, it is possible to remove and clean only the brush body 13.

  FIG. 4 shows a side view of the brush holder 23 attached to the inner blade holder 22. The tip of the brush body 13 in the brush holder 23 is fixed so as to circumscribe at least the bottom of the valley portion of the inner blade 12 by the cutter blade.

  Next, the operation of the electric shaver 1 to which the present invention is applied will be described.

  First, when the switch button 2 is pressed and inputted by the user, based on this, a motor (not shown) rotates and the inner blade 12 is rotationally driven. The user can introduce a wrinkle into the wrinkle introduction hole of the outer blade by pressing the jaw or cheek against the outer surface of the outer blade 11, and these are shaved by the inner blade 12 and the outer blade 11 that are driven to rotate. It will be.

  Further, since the inner cutter 12 is in a state in which the brush body 13 is always circumscribed even during the rotational drive, at least the shavings and sebum adhering to the valleys of the cutter blade are removed by the brush body 13. It becomes possible to do.

  FIG. 5 is a diagram for explaining the function and effect of the present invention. When the brush body 13 is not always circumscribed with respect to the inner blade 12, as shown in FIG. 5 (a), when the outer blade 11 is pressed against the jaw 41 and the heel is introduced into the heel introduction hole, In the valley portion of the blade 12, the fluff 42 and the like accumulate, and the sharpness deteriorates. On the other hand, when the brush body 13 is always circumscribed with respect to the inner blade 12 as in the present invention, the outer blade 11 is pressed against the jaw 41 as shown in FIG. Even if the wrinkles are introduced, the fluff 42 does not accumulate in the valleys of the inner blade 12, and the sharpness is not deteriorated.

  That is, in the electric shaver 1 to which the present invention is applied, it is possible to always remove hair chips and sebum even during actual use. In particular, the hair chips and sebum accumulate in the valleys of the cutter blade. Can be prevented. For this reason, in the electric shaver 1, the sharpness can be constantly improved, and an excellent hygiene configuration can be obtained. In the present invention, since the inner blade 12 can be cleaned at the same time as the use of the electric razor 1, the use is not stopped every time the cleaning is performed, and further, the work burden on the user accompanying the cleaning is reduced. It is also useful in that it can.
