Description

[Detailed description of the invention] 【Technical field】

The present invention includes a main blade consisting of an outer cutter provided with a large number of cutter holes and an inner cutter that slides on the inner surface of the outer cutter, and a trimmer blade that is formed of a fixed cutter and a movable cutter that slides into contact with the fixed cutter. This is related to the electric shaver that is provided.

[Background technology]

The main blade consisting of the outer cutter and inner cutter cuts the hair introduced through the outer cutter hole between the inner cutter and the edge of the outer cutter hole, and cuts the hair short (shaved). However, the disadvantage is that long hair is not introduced efficiently into the blade hole.On the other hand, trimmer blades are effective in cutting long hair, but they have the disadvantage that they cannot shorten the shave. For this reason, when cutting long hair, you can get good results by first shaving roughly with the trimmer blade and then finishing with the main blade. As an electric shaver equipped with a main blade and a trimmer blade, for example, the one shown in FIG. 10 has already been provided. In FIG. 20 and a movable blade 21. Since this electric shaver is equipped with the trimmer blade 2 and the main blade 1, it is possible to perform the above-mentioned rough shaving and finishing shaving. However, because the trimmer blade 2 is attached to a part of the outer wall surface of the blade frame 4 by the presser cover 22, the distance K between the top of the outer blade 10 and the cutting edge of the trimmer blade 2 is long and they are separated. Therefore, when applying the trimmer blade 2 to 1S to cut long hair H, the main blade 1 separates from the skin S.
For this purpose, after rough shaving with the trimmer blade 2, the main blade 1
As shown in the figure, it is not possible to perform a finishing shave continuously, and as shown in the figure, it is necessary to first perform a rough shave, and then change the way it is applied to the skin S and perform a finishing shave. Ta. That is, in conventional electric razors, the main purpose of the trimmer blade 2 was to cut sideburns, and for this reason, the trimmer blade 2 was used as a pre-treatment before cutting long hair with the main blade 1. There was a lack of thought to use it.

[Purpose of the invention]

The present invention has been developed in view of these points, and its purpose is to enable rough shaving using the trimmer blade and subsequent finishing shaving using the main blade to be performed as a continuous operation. The purpose of the present invention is to provide an electric shaver that can be operated reliably.

[Disclosure of the invention]

Therefore, the present invention has a main blade formed of an outer cutter having a large number of cutter holes, an inner cutter that slides on the inner surface of the outer cutter, a fixed cutter, and a movable cutter that slides on the fixed cutter. In this reciprocating electric shaver, the outer cutter is held within an outer cutter frame formed as a rectangular frame, and the inner wall surface of the outer cutter frame and the outer cutter are held close to each other. The main blade and the trimmer blade are both located within the outer blade frame, so both blades can be placed close to each other. For this purpose, the main blade and the trimmer blade can be applied to the skin at the same time.The present invention will be described in detail below based on an embodiment of the reciprocating electric shaver shown in the drawings. , Figures 2 and 1, 3
As shown in the figure, the main body 5 is equipped with a motor (not shown).
An outer cutter 10 of the main cutter 1 and a pair of trimmer blades 2, 2 are attached to the upper end via a blade frame 4, and each trimmer blade 2 is a blade attached to the inner wall surface of the blade frame 4. A fixed blade 20, a movable blade 21, and a presser spring 23 for pressing the movable blade 21 against the fixed blade 20 are sequentially disposed on the upper surface of the base 24, and by covering the presser cover 22, the above-mentioned members 20, 21, and 23 are pressed against the blade. It is configured by being attached to a base 24. The outer cutter 10 of the main cutter 1 is made of a thin metal plate, and has a pair of locking holes 16 at both ends, and is located inside the blade frame 4, which is formed as a rectangular frame. The knife is attached to the blade frame 4 by locking a plurality of seven hooks 41, 41 protruding from the wall surface into each locking hole 16. As shown in FIGS. 2 and 1 and 3, the blade base 24 of the trimmer blade 2 has a pair of mounting pieces 25 extending downward from both ends.
．． 25 is integrally provided in a protruding manner, and a trimmer driver 26 is integrally provided in the center, and each pair of connecting pieces 28 and 7 pieces 29 are directed downward from between each mounting piece 25 and the trimmer driver 26 and integrated. The mounting piece 25 and the connecting piece 28 are connected to the mounting groove 42 formed on the inner wall surface of the blade frame 4.
43, and the hooks 29 are engaged with the click grooves 44, thereby being attached to the inside of the blade frame 4. At this time, the holding cover 22 covers both sides of the outer cutter 10 so that only the center part of the outer cutter 10 faces the upper opening of the blade frame 4. Further, the cutting edge of each trimmer blade 2 is oriented in a direction away from the main blade 1 and slightly upward. The attachment m42 in the blade frame 4 is formed between a rib 45 protruding from the blade frame 4 and the inner wall surface of the blade frame 4, and the attachment groove 43 is formed between the pair of ribs 46, 46 and the outer blade 10 for attachment. 7 Tsuku 41
Further, a click groove 44 is formed on one surface of the lip 46. The trimmer driver 26 in the blade base 24 is connected to the blade base 24.
It is integrally formed with a pair of thin elastic pieces 27 and 27 between the main blade 1, and its lower end is connected to an engaging pin 60 that protrudes from a driver 〇 that reciprocates the inner cutter 11 of the main blade 1. At the same time, the upper end, which penetrates the blade base 24 and projects upward, engages with the movable blade 21. For this reason, when the driver 6 for reciprocating the inner cutter 11, which constitutes the main cutter 1 together with the outer cutter 10, performs reciprocating vibration, the movable blade 21 also performs reciprocating vibration via the trimmer driver 26. . Since the trimmer driver 26 is integrated with the blade base 24, no special member is required for power transmission, and the number of parts is small, resulting in excellent assembly. Now, as is clear from the above description, the outer cutter 10 and the pair of trimmer blades 2, 2 are both attached to the inside of the blade frame 4, and each trimmer blade 2 is attached to the inner wall surface of the blade frame 4 and to the outside. It is located between the blade 10 and the blade 10. For this reason, the separation K from the top of the outer cutter 10 to the cutting edge of the trimmer blade 2 is shorter than when the trimmer blade 2 is attached to the outside of the blade frame 4, as shown in Figure @7. As shown, when the top portion of the outer cutter 10 is exposed to the skin Sll, both trimmer blades 2, 2 also come into contact with the skin Sll. Furthermore, due to the presence of the wind contact gamma id 47 formed at the opening edge of the blade frame 4, the tops of both trimmer blades 2, 2 and the outer blade 10 come into contact with the skin S at the same time, and the hair H is removed by any of the blades. A state in which cutting can be performed can be achieved reliably and easily. In this state, when the electric razor is moved in the direction shown by the arrow in Fig. 7, the long hair H is first cut and shortened by the trimmer blade 2, and then further cut by the main blade 1, giving a short shave once. You can get it. This allows you to perform a rough shave and a final shave at the same time. Incidentally, since the pair of trimmer blades 2.degree. 2 are located symmetrically on both sides of the main blade 1, rough shaving and finishing shaving can be performed at the same time even when moving in the opposite direction. The purpose of setting the cutting edge direction of each trimmer blade 2 in the direction away from the main blade 1 is to introduce the long hair H into the comb-shaped cutting edge of the fixed blade 20 and cut it between it and the movable blade 21. This is because the rough shaving is made to be smooth and the cutting efficiency for rough shaving is high. As shown in FIG. 6, the trimmer blade 2 configured as described above has a width W that is approximately the same as that of the main blade 1, which increases the effect of simultaneous use of the trimmer blade 2 and the main blade 1. It is preferable. By the way, in this electric shaver, even if you try to apply only the trimmer blade 2 to the skin S, the basic state is such that the trimmer blade 2 and the main blade 1 are in contact with the skin S at the same time as described above. , Wind hit id 47 gets in the way. However, it is also conceivable to use the trimmer blade 2 alone, as when it is desired to cut off any length of hair H on the legs, for example, 3oII11. For this purpose, one of the pair of trimmer blades 2 attached to the blade frame 4 is made to be able to slide freely along the inner surface of the blade frame 4, and a slider is arranged on the outer surface of the blade frame 4. A bottle 48.48 protruding from the button 40 is connected to a connecting piece 28.28 of the blade base 24. If the slide button 40, which can be slid freely by locking the seven hooks 49 to the rim of the opening provided in the blade frame 4, is moved upward, one of the two buttons will open as shown in FIG. The trimmer blade 2 is thick (protruding), as shown in Figure 9.
The trimmer blade 2 can be used alone. In addition, as shown in FIG. 5, the seven hooks 29 provided on the slidable trimmer blade 2 are formed on one side of the lip 46 by 2 m! according to the vertical sliding thereof. The trimmer blade 2 is locked in the click grooves 44 and 44 at the locations, and the trimmer blade 2 is prevented from being inadvertently retracted. The outer cutter is held in an outer cutter frame formed as a frame, and a trimmer blade is disposed between the inner wall surface of the outer cutter frame and the outer cutter, and the main blade and the trimmer blade are Since both of the two blades are located within the outer cutter frame, both blades can be placed close to each other, and this allows the main blade and the trimmer blade to touch the breast at the same time. Not only can you perform a rough shave with the trimmer blade and a final shave with the main blade at the same time, but also because the rough shave with the trimmer blade is performed immediately before the final shave with the main blade, even for long hair that cannot be cut with the main blade. With just one operation, you can get a satisfactory shave.
