In the following, the head portion is disposed such that the direction in which the plurality of outer blades are juxtaposed is the front-rear direction (shaving direction) X, the direction in which each outer blade extends is the left-right direction Y, and the outer blades face upward. The vertical direction in the state is described as the vertical direction Z. Moreover, the side in which the switch part of the electric shaver is provided is demonstrated as front-back direction X front.

The electric razor 1 concerning this embodiment is provided with the holding part 2 hold | gripped by hand, and the head part 3 supported by the holding part 2, as shown in FIG.

The grip portion 2 includes a grip portion main body 21 made of synthetic resin, and in the grip portion main body 21 is formed a switch portion 22 which turns on / off driving of the rotary motor 110 (see FIG. 2) of the drive mechanism 100. It is done. Further, in the front view of the electric shaver 1 (in the state where the electric shaver 1 is viewed from the side provided with the switch), contact terminals 23 are provided in a projecting manner at both ends of the grip portion main body 21. The contact terminal 23 is electrically connected to the rechargeable battery 120 built in the inside of the grip portion body 21 through the lead wire 23a. Then, the electric shaver 1 is placed on a charging stand (not shown), and charging can be performed by bringing the contact terminals 23 into contact with the contact portions of the charging stand. Moreover, the trimmer unit 4 is formed in the electric razor 1 according to the present embodiment, and the trimmer handle is provided on the back side of the grip portion body 21 (rear side: the side opposite to the surface on which the switch portion 22 is formed). 41 is mounted slidably in the vertical direction. A trimmer blade 41a is formed at the upper end of the trimmer handle 41, and the trimmer handle 41 is held by a holding frame 42 (see FIG. 2). The trimmer unit 4 may not be provided.

The grip portion main body 21 forming the outer wall of the electric razor 1 is configured by joining a plurality of divided bodies. The plurality of divided bodies can be joined together by using a screw 84 or by fitting the divided bodies together. A cavity is formed in the inside of the grip portion body 21. Various electrical components are accommodated in the cavity.

In this embodiment, as shown in FIG. 2, the rotary motor 110, the rechargeable battery 120, etc. are housed in a sealed space formed by joining the front housing 25 and the rear housing 26 via the O-ring 26a. ing.

The rechargeable battery 120 is attached to the battery base 121 so as to abut on the battery anode fitting 122 and the battery cathode fitting 123, and the battery anode fitting 122 and the battery cathode fitting 123 are electrically connected to the circuit board 124. .

second driving elements

130 and 140.

The rotary motor 110 is housed in the grip portion main body 21 below the head case 71 in a state where the rotary shaft 111 is projected into the drive mechanism housing portion 72.

Further, as the conversion mechanism 180, a known one can be used. For example, the rotational motion of the rotary motor 110 can be converted into reciprocating motion by eccentrically providing the eccentric shaft from the rotary shaft 111 of the rotary motor 110. it can. At this time, if two eccentric shafts are provided with a phase difference of 180 ° around the rotation shaft 111 of the rotation motor 110, the rotational motion of the rotation motor 110 is opposite to the opposite phase of the first driving element 130 and the second driving element 140. Can be converted to the reciprocating motion of

The first and

second driving elements

130 and 140 are provided with inner

blade attachment portions

131 and 141 to which the inner blade 54 is detachably attached.

Reference numerals

131a and 141a in FIG. 2 denote springs for urging the inner blade 54 upward, and 131b and 141b denote stoppers for holding the

springs

131a and 141a in a state of urging them upward.

In the present embodiment, in the drive mechanism 100, a portion other than the mounting portion to which the rotary motor 110, the inner blade 54 and the trimmer blade 41a are attached is housed in the drive mechanism housing portion 72.

Thus, the space S can be cleaned more efficiently.

Further, according to the present embodiment, the non-slip portion 24 is provided at the central portion 1 b of the front surface 1 a of the electric razor 1. Thus, by providing the non-slip portion 24 in the central portion 1 b of the front surface 1 a of the electric razor 1, it is possible to prevent the thumb placed when the user grips the grip portion 2 from slipping. It is possible to suppress erroneous operation of the operating element 203 for opening and closing the opening window 210 more reliably.

Further, according to the present embodiment, since the non-slip portion 24 is provided below the operation element 203, the thumb placed when the user grips the grip portion 2 is temporarily shifted to the left and right. Even in the event of a drop, since there is no operating element 203 in the shifted portion, it is possible to further suppress erroneous operation of the operating element 203 for opening and closing the opening window 210.

Further, according to the present embodiment, the edge 54 d of the inner blade 54 and the opening window 210 overlap in the vertical direction in the front view of the electric razor 1. As described above, by forming the opening window 210 in the vicinity of the edge 54 d of the inner blade 54 where body hair tends to be accumulated, body hair can be more smoothly discharged from the opening window 210.

Further, according to the present embodiment, the edge 54 d of the inner blade 54 in the front view of the electric razor 1 overlaps the opening window 210 in the vertical direction regardless of the state of reciprocation relative to the outer blade 51. It is like that. In this way, the hair can be discharged from the opening window 210 more smoothly.

Further, according to the present embodiment, the inner

blade mounting portions

131 and 141 do not overlap the opening window 210 in the vertical direction in the front view of the electric razor 1. In this way, it is possible to suppress that the water introduced from the opening window 210 can not reach the inner side (back side) by hitting the inner

blade mounting portions

131, 141, and the cleaning performance in the space S is further improved. Will be able to

Further, according to the present embodiment, the head case cover 81, which is the lower surface portion defining the space portion S, is formed with the inclined portion 81c that is inclined toward the opening window 210 from the central portion in front view of the electric razor 1. ing. By so doing, the water in the central portion of the head case cover 81 can easily flow along the inclined portion 81 c and toward the opening window 210, so that the space S can be cleaned more efficiently. In the present embodiment, the upper surface of the head case cover 81 is inclined forward and downward in a state where the electric razor 1 is erected (the state shown in FIG. 4: the grasping portion 2 is substantially vertical). I have to. That is, the side where the opening window 210 is provided is inclined downward. Therefore, there is also an advantage that drying in the space S can be performed more efficiently with the electric razor 1 standing.

Further, according to the present embodiment, it is possible to open and close the plurality of opening windows 210 by one operation element 203. As described above, since the plurality of opening windows 210 can be opened and closed by one operation element 203, the plurality of opening windows can be opened and closed in one operation, so that the opening windows 210 can be opened and closed easily. Will be able to

Further, by providing the operating element 203 in any one of the plurality of opening windows 210, the degree of freedom in installing the operating element is improved, and the design can be improved.

As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible.

For example, in the above embodiment, the inner blade may be reciprocated using a rotary motor and a conversion mechanism.

According to the present invention, it is possible to obtain an electric shaver capable of suppressing erroneous operation of the operating element for opening and closing the opening during use.
