2. Description of the Related Art Reciprocating electric shavers usually have only one blade head, and as a result, vibrations in the direction of the reciprocating motion are transmitted to the hand that grips the main body case, causing discomfort. To solve this problem, there are two blade heads, and a pair of movable blades arranged parallel to each other in each blade head are reciprocated in opposite phases, so that the vibrations in the reciprocating direction are canceled out by each other. There is something I did.

In this case, it is necessary to provide a plurality of drive elements to cause the movable blade in each blade head to reciprocate, and to cause these drive elements to perform reciprocating motion with different phases. The device disclosed in Japanese Patent No. 47-13139 uses an eccentric cam and a slot that engages with the eccentric cam. In addition, there is also a device in which a pair of reciprocally movable drivers having elastic legs at both ends and a pair of eccentric shafts that rotate are connected by links.

In addition to the high sliding noise of the engaging part, the point of transmitting force to the driving member moves, so the frictional force generated in the engaging part in a direction perpendicular to the direction of reciprocating motion causes the driving member to vibrate. It has the following drawbacks.

36, the pair of drive elements 41,
42 performs reciprocating motion in opposite phase, but since the pair of drivers 41 and 42 are arranged in parallel, the line connecting the connecting points of each driver 41 and 42 with the links 35 and 36 is , intersects with the reciprocating direction X of the drivers 41 and 42, and as a result, as shown in FIG. Moreover, the reciprocating stroke becomes shorter than twice the amount of eccentricity of the eccentric shafts 32 and 34, resulting in a load loss of the motor 3.

A pin 47 protruding from the drive element 42 is connected to the motor 3 by the motor 3.
When 34 rotates, links 35 and 36 are attached to the mounting base 20.
The driving elements 41 and 42, which are fixed at both ends with screws 39 and are easily flexible in one direction due to the presence of elastic leg pieces 410 and 420, are caused to reciprocate.

At this time, each eccentric shaft 32, 34 is connected to the motor 3.
The pins 47 of one drive element 42 are provided at symmetrical positions sandwiching the rotation center O, that is, at positions shifted by 180 degrees, and as is clear from FIG. By protruding from the piece 421 that has sunk under the driver element 41, the driver element 41
The pin 46 protruding from directly below, the rotation center O, and the pin 47 are aligned on a straight line parallel to the reciprocating direction X of both the drivers 41, 42. As a result, both drive elements 4
1 and 42 move in opposite directions, that is, both drive elements 41,
The phases of the reciprocating motions of the drive elements 41 and 42 differ by 180 degrees so that the vibrations cancel each other out, and vibrations in the direction Y perpendicular to the reciprocating direction X do not occur in both drive elements 41 and 42, and furthermore, the eccentric The reciprocating stroke of the drivers 41, 42 is twice the eccentricity of the shafts 32, 34. The links 35 and 36 may be formed integrally with the drivers 41 and 42 to have elasticity.

Note that the flat portions 310, 330 provided on the side surfaces of the bases 31, 33 make the directionality of both the bases 310, 330 clear, making it easier to improve accuracy during assembly. Base 31
The stepped portion 311 provided at the base 31 can be used as a pressing surface when attaching the blocks of the bases 31, 32 and the link 35 to the output shaft of the motor 3 by press fitting, and press fitting can be performed without pressing the base 33. That's what I do. The link 36 is attached to the pin 47 side and the tip of the pin 47 is heat-sealed to prevent it from coming off, thereby improving assembly efficiency.

Furthermore, the reason why the piece 411 is provided on the drive element 41 side to cover above the piece 421 is to increase the creepage distance from the upper surface opening of the main body 2 through which the connecting tubes 43, 43 pass through to the eccentric shaft 34. , prevents the packing 70 from falling toward the drive elements 41 and 42 when cleaning lint, and also prevents the link 3
It also prevents the sound generated by the 5 and 36 from leaking to the outside. Wall 4 hanging from each drive element 41, 42
12,422 is also for preventing this sound leakage. Furthermore, wall 4
A window 413 provided at 12 is a viewing window for convenience during assembly.

Furthermore, the screw 3 in each drive element 41, 42
Both ends clamped and fixed between the mounting base 20 and the inner surface of the main body 2 by the 9 are not only partially overlapped vertically, but also so that the protrusions 416, 426 and the recesses 417, 427 engage with each other. In addition, the protrusions 201 and 2 protruding from the mounting base 20 are
02 is a recess 417, 428 in each drive element 41, 42
Since the drive elements 41 and 42 are engaged with each other and the direction of engagement matches the direction in which the drive elements 41 and 42 are assembled to the mounting base 20, it is easy to position and fix the drive elements 41 and 42 when installing them. It has become.

In addition, when the motor 3 is mounted on the mounting base 20, a vibration isolator 80 made of an elastic material is fixedly placed on the surface of the motor 3 as shown in FIG. As shown in FIG.
An elastic body 303 made of rubber or the like is interposed between the
Even if the rotating shaft 300 receives a lateral load, the deflection is caused by the elastic body 30.
3, so that the motor 3 itself also has a soundproofing effect. As mentioned above, the drive elements 41, 4
Since the vibrations associated with the reciprocating drive of motor 2 are canceled out, it is no longer necessary to firmly fix the motor 3, which makes it difficult for the sound and vibrations generated by the motor 3 itself to be transmitted to the main body 2. That's how I do it.

As shown in FIGS. 10 and 11, the joint 45 connecting the driver 41 and the trimmer driver 62 has thin blades 450 integrally protruding from both sides in the reciprocating direction. This is provided so that the joint 45 itself covers the gap between the main body 2 and the cover 63, which is the space in which the joint 45 can move, and prevents beard debris from falling into the interior. The wing pieces 450 are assembled so as to be in contact with the upper surface of the holding plate 71. Compared to the case of disposing a dustproof member using maltplane or the like, it has the advantage that there is less frictional resistance and the load due to sliding can be reduced, and that it does not turn over when cleaning beard debris.

FIGS. 17 and 18 show another embodiment of the present invention, in which the base 31 is provided with a biasing portion 315 as a balance weight. That is, link 3
If F1 is the driving force of the drive element 41 caused by the link 36, F2 is the driving force of the drive element 42 caused by the link 36, and F3 is the centrifugal force caused by the biasing portion 315, then by making F1=F2+F3, this bias can also be reduced. By providing the volume portion 315 on the side closer to the motor 3, stable rotation and vibration reduction are achieved.

As described above, since the present invention includes a pair of drivers that reciprocate in opposite phases, the vibrations in the reciprocating direction of the drivers cancel each other out. Moreover, the pair of eccentric shafts are arranged symmetrically at positions sandwiching the center of rotation, and the connecting points of the links connecting these eccentric shafts and each driver with the driver are parallel to the reciprocating direction of the driver. In addition, since it is provided on a straight line passing through the rotation center, there is no vibration in any of the drivers in a direction perpendicular to the direction of reciprocating motion, and the vibration is small and there is no discomfort. Moreover, since the reciprocating strokes of both drive elements have a maximum value twice the eccentricity of the eccentric shaft, the efficiency of power is good.
