Description

[Detailed explanation of the idea] The present invention relates to an electric razor with a trimmer mechanism.

In this type of electric razor with a trimmer mechanism, the trimmer mechanism performs the edge shaving function, and the trimmer mechanism is movable toward the net blade, allowing the trimmer mechanism to cut curly hair and long hair while cutting the net blade. Preferably, the shaver is configured to be shaved by.

However, in conventional electric razors with a trimmer mechanism, when the trimmer mechanism is brought close to the net blade after being used alone, the trimmer mechanism must be moved upward after returning to its original position. It was time consuming and complicated.

Further, if the trimmer mechanism is forcibly moved upward while it is rotated and protruded, there is a risk of malfunction.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and to provide an electric razor with a trimmer mechanism that is configured to be movable upward even when the trimmer mechanism is in a protruding state, thereby improving usability and preventing the occurrence of malfunctions. shall be.

In Figures 1 to 6, 1 indicates a storage battery 2 and a motor 3.
The body has a built-in blade, and an external force frame 5 holding an outer blade, that is, a net blade 4, is attached.

Reference numeral 6 denotes an inner blade that is slidably installed inside the net blade 4, and as is well known, is pressed against the net blade 4 by a push-up spring 7, and receives the output of the motor 3 in the body 1 to act as an eccentric cam 8. It is also provided so that it can reciprocate via a drive arm 9.

10 is a net 4 as a whole on one side of the outer cutter frame 5.
A trimmer mechanism attached obliquely to a pair of guide frames 11, 11. A moving plate 12 and a trimmer base 13 are included.

The guide plate 11.11 has a curved surface 15.15 that faces the curved surface 14.14 of the outer cutter frame 5 and defines an arcuate channel, and is formed at the curved surface 14.14. A fixing pin 18.19 protrudes and can be inserted into the fixing hole 16.17.

On the other hand, the movable plate 12 has a concave-shaped large cutout 20, and the bottom surface of the large cutout 20 is formed as a tapered surface 21 that slopes inward.

Further, on both sides 22.22, a curved surface 14.14 of the outer cutter frame 5 and a curved surface 15.1 of the guide frame 11.11.
Curved tabs 23, 23 extend slidably within the arcuate channel formed by the tabs 15 and 15.

Further, a recess 25 is provided on the lower surface of one end in which the operating lever 24 can be accommodated, and a relief groove 27 is provided on the end surface of the lug 23 for guiding a hook spring 26 fixed to the operating lever 24 and extending in an arc shape. is formed.

The operating lever 24 is pivotally supported within the recess 25 via a pin 28 so as to be slightly rotatable, and is normally fixed within the recess 25 under the spring force of a leaf spring 29.

In addition, the hook portion 30 at the upper end of the hook spring 26 has one ear piece 2.
It is located so that it slightly protrudes inward from 3.

Further, the trimmer base 13 is attached to the side portion 22 of the movable plate 12.
, 22, the lower surface of which is provided as a tapered surface 32 that can rub against the tapered surface 21 of the moving plate 12.

Further, a rotating shaft 34.34 is horizontally protruded from the lower part 31 and is pivotally supported in a shaft hole 33.33 provided in the side part 22.22.

Moreover, one end of the one rotating shaft 34 is connected to the movable plate 1.
2, a torsion spring 3 whose other end is locked to the trimmer base 13;
5 is wound around the movable plate 12, and a trimmer base 13 is provided so as to rotate and protrude from the movable plate 12.

Further, a recess 36 into which the hook portion 30 of the hook spring 26 is inserted is formed at one end of the trimmer base 13.

In addition, a fixed blade 37 having an L-shaped blade part with fresh oil at the tip is fixedly installed on the trimmer base 13, and a gap between the trimmer base 13 body and the fixed blade 37 is fixed to the fixed blade 37. The drive rod 38 of the drive body 9 is slidably provided in the drive rod 38 of the drive body 9.
It includes a movable blade 40 driven by a trimmer drive element 39 that can be locked with the trimmer drive element 39 .

Reference numeral 41.41 is a return spring whose one end is locked to the guide plate 11.11 and whose other end is locked to the upper edge of the ears 23, 23 of the movable plate 12, and functions to always push the movable plate 12 downward.

42 is a switch plate slidably attached to the body 1;
It is provided so that the moving plate 12 can be pushed up,
Further, as is well known, it is provided so as to be held in the upward movement position by a lock button 43 during upward movement, and the electric circuit to the motor 3 is closed.

Furthermore, the operation of the present invention will be explained in detail.

Now, in the state shown in FIG. 2, the switch plate 42 is in the downward movement position, the movable plate 12 is not moved upward, and the trimmer drive element 39 engaged with the movable blade 40 is not engaged with the drive rod 38 of the drive body 9. Therefore, the trimmer mechanism 10 is not driven.

On the other hand, if the operating lever 24 is slightly rotated clockwise against the spring force of the leaf spring 29 from the state shown in FIG. 36, the trimmer base 13 is rotated by the spring force of the torsion spring 41 about the rotating shaft 34, 34 as a fulcrum,
made to stand out.

At the same time, the l-IJ motor driver 39 is locked to the drive rod 38 of the drive body 9, and the movable blade 40 is slid against the fixed blade 37, so the trimmer mechanism can be used alone to perform the edge shaving operation. I can make you do it.

Furthermore, if the switch plate 42 is pushed up from the state shown in FIG. 4 as shown in FIG.
．． Since the trimmer drive element 39 moves obliquely upward and along an arc-shaped trajectory within the channel defined by the curved surfaces 15 and 15 of the drive body 9, the movable plate 12, As a result, the entire trimmer mechanism 10 moves upward toward one side of the net blade 4, and when the switch plate 42 is further moved upward, the trimmer mechanism 10 approaches the net blade 4 as shown in FIG.

At this time, the movable plate 12 of the trimmer mechanism 10 moves upward while coming into contact with the tapered surface 32 formed on the base 31 of the trimmer base 13 via the tapered surface 21. .34 as a fulcrum, and when the trimmer mechanism 10 is in a position close to the net blade 4 as shown in FIG. 6, the hook portion 30 of the hook spring 26
is engaged in the recess 36 to bring the trimmer board 13 into the retracted state.

In addition, if the switch plate 42 is pulled down from the state shown in FIG.
The movable plate 12 and the trimmer base 13 are moved downward by the spring force of the return spring 41, allowing the trimmer mechanism 10 to return to the non-use state shown in FIG. 2.

According to the electric razor with a trimmer mechanism of the present invention configured as described above, even if the trimmer mechanism is in the protruding state, it can be immediately moved up to form a net blade, and the usability can be significantly improved. Realize the effect.
