Description

[Detailed description of the invention] The present invention relates to the structure of an electric razor.

Generally, conventional electric razors equipped with a trimmer are equipped with a trimmer base fixed to the main body or tilted, or equipped with a trimmer tilted around the lower edge of the base.

However, the former uses only the trimmer base,
Alternatively, the main blade must be used alone, and the protruding portion of the cutting blade on the trimmer base may get in the way when only the main blade is used, which is inconvenient.

In addition, the latter method has the disadvantage that the structure for mounting the trimmer base on the main body is complicated, so that beard debris may enter the main body during assembly and use.

The present invention has been made in view of the above-mentioned conventional problems, and is intended to improve these drawbacks.
An object of the present invention is to improve the main blade.

The object of the present invention is to bring the main blade and the cutting blade of the trimmer close to each other to assist the main blade's action, and to equip the main body with a device so that the trimmer can be used alone or only the main blade can be used alone. The company provides an electric razor with

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a main body housing a motor 2 and a power supply section in its inner space, a main blade section A is mounted on its upper edge, and a trimmer B is rotatably mounted on its abdomen.

The main blade part A has an outer cutter 3 having a plurality of hair introduction holes formed in a substantially semi-cylindrical shape, and an inner cutter 4 that is in sliding contact with the inner surface of the outer cutter 3, and the inner cutter 4 is mounted on the base 10. has been done. This base 10 is connected to a driver 6, and an eccentric cam 7 mounted on the shaft 2a of the motor 2 is engaged with the driver 6. 8 is a bevel gear mounted on the lower part of the shaft 2a, and 9 is a bevel gear mounted to mesh with the bevel gear 8 and supported by a bearing on the side of the motor 2.

The trimmer base 5 has a flat plate-like enclosure, and is attached by a hollow rod 16 protruding from the inner surface thereof being rotatably inserted into and connected to a shaft hole 19 in the main body region.

The trimmer driver 11 is disposed inside the trimmer base 5 and equipped with an eccentric cam 13 at its lower end.The eccentric cam 13 is connected to the shaft 17 of the bevel gear 9 via a hollow rod 16. The intermediate portion is pivotally supported by a pin 18 protruding from the inside of the trimmer base 5. When the eccentric cam 13 is swung by the shaft 17, the trimmer driver 1 is rotated about the pin 18 as a fulcrum.
The cutting blade 12 at the upper end of the cutting blade 1 is swung.

The trimmer base 5 is connected to the abdomen of the main body via a hollow rod 16, so it is rotatable around the hollow rod 16, and the trimmer driver 1
1 is also supported on this trimmer base 5 by a pin 18, and the eccentric cam 1 is mounted at the center of the hollow rod 16.
6 and shaft 17 are connected, trimmer base 5
Rotates according to the rotation of.

This trimmer base 5 is fixedly supported at a predetermined position by engagement between a latch pin 14 provided on the abdomen of the main body and a latch recess 15 provided on the inner surface of the trimmer base 5.

It is desirable to provide the holding devices, which are made up of the latch pin 14 and the latch recess 15, at four locations on the upper and lower sides and on the left and right sides of the abdomen of the main body in order to stably support the trimmer base 5 at four predetermined positions as exemplified below.

In this way, as shown in FIGS. 2 to 5, the main blade of the trimmer B can be placed in a position dedicated to short beards with the main blade facing downward, and the cutting blade 12 of the trimmer B can be directed to either side. The trimmer base 5 is fixedly supported in two positions: a position dedicated to shaving long hair with the trimmer B, and a position where the cutting blade 12 of the trimmer B faces upward and is close to the main blade to assist the main blade in shaving. .

Now, when the motor 2 is rotated, the eccentric cam 7
rotates and the driver 6 is reciprocated, and the driver 6
The base 10 engaged with the blade is reciprocated, the blade surface of the inner cutter 4 comes into sliding contact with the inner surface of the outer cutter 3, and the beard inserted through the beard introduction hole is shaved.

Also, the bevel gear 9 meshed with the bevel gear 8 also rotates.
By the action of the eccentric cam 13, the trimmer driver 1
1 swings and the cutting blade 12 of the trimmer B reciprocates to shave long or curly hair.

In this manner, in order to shave long hair or curly hair with a trimmer, the cutting blade 12 is directed toward the side of the main body and protrudes from the main body.

When only the main blade 3 is used, as shown in Fig. 4, rotate the trimmer so that the cutting blade 12 faces downward and closes to the abdominal surface of the main body so that it does not interfere with the use of the main blade 3. Securely support it so that it does not become damaged.

Furthermore, by rotating the trimmer and equipping the main blade 3 with the cutting blade 12 in close proximity, the two blades can assist each other and work together to shave short and long hair.

As described above, the electric razor of the present invention has a box-shaped main body equipped with a main blade for shaving short beards on the upper edge thereof, and a trimmer base equipped with a cutting blade for shaving long beards on one end edge thereof. Since it is equipped to be rotatable within the plane of the main body and can be fixed and supported at a predetermined position within the plane of the abdomen of the main body, the mounting structure to the main body can be simplified, and when shaving short and long beards, Since it is sufficient to simply rotate the trimmer base, there is an effect that handling can be performed easily.

Furthermore, if the trimmer base can be fixed and supported at a predetermined position within the plane of the abdomen of the main body, the main blade can be used exclusively for shaving short hair, or the cutting blade can be used alone. If the blade is placed close to the blade, the two blades will work together to shave effectively.
