[Means to solve the problem]

Therefore, the present invention provides a trimmer support plate, a trimmer blade block supported by the trimmer support plate, a trimmer drive element pivotally supported by the trimmer support plate, and a drive element that converts rotational motion of a motor into reciprocating motion. In an electric shaver trimmer device in which the movable blade and the drive element in the trimmer blade block are connected by the trimmer drive element, the trimmer drive element is connected to the rear side of the trimmer support plate on which the trimmer blade block is arranged on the front side. The trimmer drive element is pivotally supported and is characterized in that a dustproof member is disposed between the trimmer drive element and the main body of the electric shaver located behind the trimmer drive element. According to the present invention, since the trimmer drive element is pivotally supported on the back side of the trimmer support plate, the opening that must be formed in the trimmer support plate in order to insert the trimmer drive element is formed by the trimmer blade. It is located on the upper side that supports the block, making it difficult for beard shavings to enter the opening, and also between the trimmer driver and the main body located behind it. The dustproof member placed in the opening can prevent beard shavings from entering the inside of the main body. [Embodiment] The present invention will be described in detail below based on the illustrated embodiment. As shown in FIG. A trimmer blade block 2 is attached to a trimmer support plate 3 that is integrally formed on the upper part of a switch handle 30. As shown in FIGS. 3 and 5, the main body 1 consists of a housing 11 and 12 divided into front and rear halves, and a cover housing 13 that covers the back side, both side surfaces, and the bottom. As shown in FIGS. , a motor 6 and a storage battery 62 are placed above it.
A drive element 4 that converts the rotation of an eccentric shaft 61 attached to the output shaft of the motor 6 into reciprocating motion is disposed in the upper part, and a main blade 5 is disposed at the upper end. An outer cutter 52 and an inner cutter 51 are arranged, and the inner cutter 51 is connected to the upper end of the drive element 4. In the figure, 50 is the outer blade frame;
14 is the outer blade frame attachment/detachment, 15 is the driver dustproof rubber, 1
6 is a dustproof rubber presser plate, and 53 is a blade protection cap. Further, Ilb and 60a in FIGS. 7 and 8 are portions for fixing the housing 11 and the mounting base 60. The switch handle 30 disposed on one side of the main body 1 is integrally equipped with the trimmer support plate 3 on the upper part as described above, and is equipped with a lock handle 31 and a switch equipped with a contact spring 33. A plate 32 is connected. And in the upper part of the trimmer support plate 3,
The trimmer blade block 2 is rotatably supported by a pair of shafts 34°34. Further, a push-up lever 45 and a trimmer driver 41 for rotating the trimmer blade block 2 are attached to the trimmer support plate 3. The trimmer blade block 2 includes a base plate 20, a fixed blade 21 and a movable blade 22 attached to the base plate 20, a guide plate 23 attached to the movable blade 22, and a movable blade 22 connected to the fixed blade 2.
1, and the tip of an arm 45b protruding from a push-up lever 45 near the shaft 34 is connected to the push-up lever 45. The push-up lever 45 is rotatably supported on the back side of the switch handle 30 and has an engaging portion 45a that engages with the outer surface of the main body 1. The push-up lever 45 presses the lock handle 31 and engages the hook portion 31a with the housing 11. The protrusion 11a
When the switch handle 30 is operated upward with the switch handle 30 removed from the switch, the arm 45b is caused to move up and down with a stroke larger than the stroke of the switch handle 30.
The trimmer blade block 2 is pushed up to cause the tip of the trimmer blade block 2 to protrude laterally as shown in FIG. Further, due to the upward movement of the switch handle 30, the contact spring 33 of the switch plate 32 short-circuits the conductive parts provided in the circuit block 7, and energizes the motor 6. The trimmer driver 41 is supported by the trimmer support plate 3 so as to be able to swing freely at its center in the vertical direction.
When the switch handle 30 is operated upward to cause the tip of the trimmer blade block 2 to protrude laterally, the upper end engaging portion 4
1b is connected to the movable blade 32 via the guide plate 33, and the lower end engaging portion 41a engages with a connector 42 protruding from the driver 4 to transmit the movement of the driver 4 to the movable blade 22. However, the trimmer driver 41 is attached to the trimmer support plate 3 as follows. That is, as is clear from FIG. 1, a shaft 35 is provided on the back side of the trimmer support plate 3 on which the trimmer blade block 2 is mounted on the front side, and the trimmer driver 41 is supported swingably by this shaft 35. The upper end engaging portion 41b of the trimmer driver 41 is guided to the front side of the trimmer support plate 3 through an opening 39 provided at the upper part of the trimmer support plate 3. A dustproof cover 47 to which a trimmer dustproof plate 48 is adhered is disposed on the rear side of the trimmer driver 41, that is, on the main body 1 side. In other words, the opening 39 formed in the trimmer support plate 3 in order to insert the trimmer drive element 41 that connects the movable blade 22 in the trimmer blade block 2 and the drive element 4,
It is formed at the upper part near the pivoted base end of the trimmer blade block 2, and is located above where the blade is located when the trimmer blade block 2 is folded and stored on the front surface of the trimmer support plate 1. Because of this position, the hair scraps cut by the trimmer blade block 2 hardly ever reach the opening 39, and therefore the absolute amount of hair debris that tries to get around to the rear side of the trimmer support plate 3 through the opening 39 is extremely small. Even if beard shavings enter the opening 39, they are prevented from entering the interior of the main body 1 by the dustproof cover 47 and the trimmer dustproof plate 48. Note that the dust cover 47 is attached to the trimmer drive element 41.
Since the trimmer dustproof plate 48 is in contact with the trimmer driver 41 near the shaft support of the trimmer driver 41, the load resistance given to the trimmer driver 41 is small. In the figure, reference numeral 49 denotes a dustproof plate that is disposed on the upper front surface of the main body 1 and slides into contact with the back surface of the dustproof cover 47 when the trimmer support plate 3 moves up and down.

【Effect of the invention】

As described above, in the present invention, since the trimmer drive element is pivotally supported on the back side of the trimmer support plate, it is possible to connect the movable blade of the trimmer blade block supported by the trimmer support plate and the trimmer drive element. The opening formed in the trimmer support plate will be provided at the top of the trimmer support plate, which makes it difficult for beard shavings to enter the opening.Moreover, even if beard shavings do get into the opening, This is because a dustproof member placed on the rear side of the trimmer driver prevents beard shavings from entering the main body.
