化かつ薄型化としうる効果を有する。 DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electric razors, particularly small electric razors. In general, electric razors, regardless of whether they are rechargeable rotary blades or dry cell rotary blades, are comprised of three main functions: a battery section, a motor section, and an inner cutter outer cutter cutter section. However, it still has the drawback of not being sufficiently miniaturized. The present invention aims to improve the above-mentioned drawbacks and provide a smaller and thinner electric razor that integrates an electric razor and a drive motor using a flat motor whose permanent magnet magnetization direction is in the rotor axis direction. The razor of the present invention has a flat rotor and a permanent magnet arranged in parallel in a motor yoke, only the motor rotor is arranged below the rotating blade of the electric razor, and a permanent magnet and a permanent magnet are arranged in the grip of the electric razor. It is characterized by configuring the dry batteries in the same motor yoke. Next, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a sectional view of the present invention, in which 1 is the outer blade of the razor, 2 is the inner blade of the razor, and 3 is the outer blade of the razor.
4 is an outer cutter frame, 4 is a waste collection, 5 is an outer cutter housing, 6 is a first motor case, and 7 is a permanent magnet constituting the motor, which is composed of first and second permanent magnets 23 and 23' as described later. ing. Further, 8 is a second yoke member, 9 is a flat rotor, 10 is a bearing stand, 11 is a bearing, 12 is a flat plate brush, 13 is a flat plate commutator, and 14 is a shaft. FIG. 2 mainly shows an exploded perspective view of the flat motor, and the same members as in FIG. 1 are designated by the same symbols.
Reference numeral 21 denotes a motor case (corresponding to 6 in Fig. 1), which is composed of a single iron plate, and includes U-shaped main bodies 21b, 21b', and a connecting part 21c.
A stepped portion is formed in the extension of each main body 21b, 21b' and bent upward to form magnetic pieces 21d, 21d', and permanent magnets 23, 23' are housed in the lower portions of the magnetic pieces. 21a indicates a groove between the main bodies 21b and 21b'. 22 is the motor case (corresponds to 8 in Figure 1)
Similarly, the U-shaped main bodies 22d, 22d, which are made of one iron plate, and the connecting part 22b at the base thereof,
A groove portion 22e for attaching the brush stand 39 is formed near the connecting portion 22b, and squeezed portions 22c for fitting the brush stand 39 are formed on both sides of this groove portion. Also, the shaft 1 of the rotor 9 is located in the middle of the groove 22c.
A receiving portion 22a for receiving 4 is formed, and a bearing 11 is provided in the receiving portion. Reference numeral 32 denotes a dry battery mounting stand made of an insulating material.Holders 32a and 32b for fixing the batteries are provided at both ends of the stand, and electrodes for contacting the batteries (not shown) are provided inside the holders 32a and 32b. Also, the electrodes are each brush 1.
2 and 12 are connected. Reference numeral 39 denotes a brush stand formed in the shape of a frame, and brushes 12, 12' are provided on both sides. 31 is an insulating cover made of non-magnetic material, and the height of this insulating cover is equal to that of the first and second permanent magnets 2.
3 and 23', and an extension 31a is formed from the cover 31.
has a hole 36 into which the rotor shaft bearing can be press-fitted.
is provided. Further, the height of this extension is the same as that of the main bodies 21b, 21b' of the motor case 21 . Further, the brush stand 36 and the dry battery mounting stand 32 are connected to the groove 22e of the yoke and the main body 22 of the yoke 22, respectively.
It is press-fitted and fixed in the space between d and 22d'. This state is shown in FIG. 3B. FIG. 3A shows a perspective view of the motor part, B shows a perspective view when the yoke and dry cell mount are assembled, and FIG. 4 shows a side view. When assembling, the brush stand 39 and the dry battery case 32 are respectively attached to the yoke 22 , and the magnetic pieces 21d, 21 of the motor case 21 are
Permanent magnets 23', 23 are housed between d' and the bodies 22d, 22d' of the yoke 22 , and the shaft 14 of the rotor 9 is
One is attached to the bearing 11 of the yoke 22 , and the other is attached to the hole 36 of the extension part 31a of the insulating cover 31 via a bearing. The brushes 12, 12' are also brought into contact with a commutator (not shown) provided on the lower surface of the rotor 9. Furthermore, the outer blade housing 5 is a motor case 21.
It is attached to the upper surface of the main body 21b, 21b'.
An electric razor can be constructed by attaching the outer cutter 1 of the electric razor to the outer cutter housing 5 via the frame 3 and attaching the inner cutter 2 to the rotor shaft 14 in advance. As described above, the present invention has a flat rotor and a permanent magnet arranged to match the shape of the electric razor body, so the thickness of the rotating blade of the electric razor is reduced.
In addition, by arranging the permanent magnet and the dry battery in the motor yoke in the grip portion, it is possible to make the electric razor smaller and thinner.
