Description

DETAILED DESCRIPTION OF THE INVENTION This Jl@ki reciprocating electromagnetic cell drive device is <11゛ゝ゛゛voice-)O.

The conventional drive device, which is an external column type (as shown in FIG. 1) and has a 1W electric power source, has a - degree as shown in FIGS. 92 and 3. That is, the eccentric pin 3 is attached to the mower I shaft 3 of the mower 11, the driver 4 is engaged with it, and the main blade SO inner cutter frame 6 and the movable blade drive protrusion 8 of the trimmer 7 are engaged with the driver 4. .

The drive element 4 is integrally formed from plastic and has a thin OS.
The reciprocating I! is mainly composed of the Sumimo algae 10 supported by the S plates 9, 9' and the lever part 11 whose one end is integrally connected to the lower surface of the reciprocating part 10. 110 is the rocking plate 9, 9
') Only reciprocating movement of arrow X is possible, m), v bar 1
111#i Arrow 1ily perpendicular to arrow X.

It is configured to be able to swing. This driver 4
■Hand 1 for the main blade for the reciprocating 1110! and) V-layer joint 13
In addition, an eccentric pin engagement hole 14 is formed in the lever part 11#i. When the motor I operates and the I-shaft 2 rotates, the eccentric pin 3 rotates and transmits the rotation to the lever part 11. During the rotation of the lever part 11 eccentric bottle 30, it is lifted by the arrow YO and the acid component is transmitted to the reciprocating part 10.

Reciprocating part 106 reciprocating operation, each connection speed is 1! , 1m is reciprocating, the main blade inner cutter frame is reciprocating, and)
Ifff said that he had performed the 9-ma operation (arrow 2),
8 engages with joint 3 from the loose state shown in Fig. 3)
An l-r operation is performed.

However, in the drive device of this reciprocating electric shaver, since the main blade 5 operates when the F reamer is driven, the noise and slow motion are large, and the load applied to the motor 1 is also large, which greatly reduces the life of the 1L battery. It had the disadvantage of being engraved.

Therefore, it is an object of the present invention to provide a drive device for a reciprocating electric shaver b that can eliminate negative 11f movement and slow movement σ.

An embodiment of the present invention is shown in FIGS. 4 to 6, that is, the drive system f#i of this reciprocating electric oven includes an ICX drive shaft 17 parallel to the shaft 11 of the motor 15. Il
Connect the shafts 16 to 18 with ears 19 to 21, and attach eccentric beams 22 and 23 to each shaft 17 and 11. These eccentric bins 22゜13K) 1-ma drive element 24 and main blade circumferential drive element 25 are engaged, and each drive element 24.2
5) When the g arm 26 and the main blade 27 are engaged, the switching lever 28 controls the engagement of the drive element 24, 25 and the eccentric pins 22 and 23. Each drive element 24.25 has the above-mentioned 11
Like the figures 2 and ga, it is made of depth stick and is supported by thin slow moving plates 29 and 29'.

31 and a shield 111 provided on the lower surface of the reciprocating part 30.31
32, 13, the slow movement 1 [29, 29' are connected to a common fixed plate 34, 35, respectively, and the two movers 24.
25 are arranged in parallel, and attached to the main body 36 with screws etc.)
Fixed. The lever part 32.33 hangs from the opposite waste side over the longitudinal direction of the reciprocating part 30.31.
It is parallel to the longitudinal direction and extends toward the summer goods, lever part 32,
Conical holes 37 and 38 are formed at the tip of 33, and a bottle engaging hole 39 is formed at the tip. Reciprocating part 30.31
) Forms 30 islands for the blade and a joint 311 for the main blade.

The switching lever 28Fi and the rotary rod 40 enter into the gap 41 between the reciprocating portions 30°31 and the lower portions of the shiso bar portions 32 and 33, and the control rod 42 is integrally formed at right angles to the tip of the rotary rod 40, and each of the control rods 42 Ahead! 1IIF! It is located in the middle of the lever part 32,33. Further, the other end S of the rotary rod 40 is exposed (to the razor body 3) and connected to the shaft 4mK.

Turn the switching lever 280 and turn 43 to the trimmer side (arrow &) [1
1, the tip of the control rod 42 pushes up the main blade side lever 1133, which disengages the engagement hole 39 from the eccentric pin z3 and separates them from each other. On the other hand, the engagement hole 39 engages with the eccentric pin 22 through the conical hole 37 due to its elasticity and the restoring action of the tensioner side lever portion 32.
Ru. When the motor 15 is operated and the motor I shaft 16 is rotated, the drive shaft 17.18 is rotated through the gears 19 to 21, and each eccentric bin 22.23 is rotated.
Since K is engaged with the lever part 32, it drives the lever part 32, and from this, the reciprocating part 30 moves reciprocally in the same way as the operation shown in FIG. 2, and drives the trimmer. In this state, move the knob 43 of the switching lever 28 to the main blade side (arrow b)
c When switched, the trimmer side lever 1132 is activated as shown in Fig. 5.
is pushed up and the engagement between the eccentric pin 22 and its retaining hole 39 is released, while the lever portion 33 is restored and the engagement hole 39 engages with the eccentric pin 23 through the conical hole 37, thus driving the main blade. will be held.

As a result, only one side is always driven by the switching operation of the switching lever 28.

As described above, the drive device for a reciprocating electric cutter according to the present invention uses a switching lever to switch the rotational power input to the main blade drive element and the trimmer drive element, so that they can be operated individually, unlike conventional This has the effect of reducing load and vibration, improving battery life, etc., and eliminating the fear of accidentally cutting hair with the main blade when using the trimmer.
