Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reciprocating electric shaver in which a comb-shaped movable blade reciprocates against a comb-shaped fixed blade to shave unwanted hair.

In the conventional reciprocating electric shaver for shaving unwanted hair, a blade holder 1' is integrally attached to the upper part of the electric shaver body, and a trimmer blade consisting of a fixed blade and a movable blade is attached from the outer circumference of the blade holder 1'. It had a protruding tip. In such a follow-up example, when shaving armpit hair, it is necessary to tilt at an angle of a〇, as shown in Figure 1a, and when shaving leg hair, as shown in Figure 1b, it is necessary to tilt at an angle of bo. There is a drawback that the electric razor body A' hits the body when shaving armpit hair as shown in Figure 1a, making it even more difficult to use. In the figure, A is the hand, the mouth is the armpit, and C is the leg. This invention has been made in view of the description of the present invention, and an object of the present invention is to convert the cutting edge angle of a trimmer blade consisting of a fixed blade and a movable blade by rotating the blade holder. To provide an easy-to-use reciprocating electric shaver capable of converting the angle of a cutting edge of a trimmer blade to an angle that facilitates shaving unwanted hair from hands, chest, armpits, etc.

The present invention will be explained in detail below with reference to Examples.

Reference numeral A denotes the electric shaver main body, which has a motor 3 serving as a driving source, a power supply block 4 consisting of a battery, etc. inside a housing 2, and a lower cover 5 screwed onto the lower end of the housing 2. There is. The motor 3 is driven by a power source from a power supply block 4, and a drive shaft 6 of the motor 3 projects upward, and a packing 7 is provided around the drive shaft 6 to protect the motor 3 from dust. It is installed. This motor 3
is held on a motor mounting base 8 to constitute a drive block B. Here, 9 is an anode metal fitting, and the power supply block 4
The electric power of the motor 3 is combined with the electric power of the motor 3. It is a switch to the I river, and turns on/off the power supply to the motor 3.
Reference numeral 11 denotes a blade mount, which is attached to the upper end of the housing 2 and has a female thread 12 provided on its inner periphery.

C is a cutting blade block, which includes a blade holder 1 consisting of a base 14 and a rotary plate 15 fixed to the base 14, a knotted mounting base 26 to which the rotary plate 15 is rotatably attached, and a comb-shaped fixed blade. 1
6. A comb-shaped movable blade 17, an eccentric shaft 18 that transmits driving force to the movable blade 17, a drive rod 19, a cover 20 that holds the eccentric shaft 18, and a joint spring 2 that prevents vibration of the eccentric shaft 18.
1st prize. A male thread 28 provided on the lower outer periphery of the cylindrical mount 26 is screwed into a female thread 12 of the blade mount 11. The trimmer blade consisting of the fixed blade 16 and the movable blade 17 is pushed up by the spring 2.
The base 1 is connected to the locking hole 22a of the base 14 with the locking hole 22a of the base 14.
It is held at 4. The eccentric shaft 18 is iron-coupled to a joint 23 attached to the drive shaft 6, and the amount of eccentricity of the eccentric shaft portion 18a applies rotational force to the drive shaft 19, which is swingably fixed to the boss 15a of the rotating plate 15 with a press-fit pin 24. is transmitted and converted into a reciprocating motion by the driving rod 19, and the leg portion 2 is inserted into the notch 19a of the driving rod 19.
The movable blade 17 is transmitted to the driver 25 that hooks the blade 5a, and the movable blade 17 is reciprocated by the driver 25. The joint spring 21 is the press-fit claw part 2
The cover 2 is fixed by 1a, and biased by the spring part 21b.
It is in pressure contact with the rib surface 18b of the shaft 18. The rotating plate 15 is fixed by ironing the recess 14a of the base 14 at the locking part 15b, and the hook part 15c of the rotating plate 15 is ironed with the hook fixing part 26a of the cylindrical mounting base 26, and the base A blade holder 1 having a rotating plate 14 and a rotating plate 15 is rotatably mounted on a cylindrical mounting base 26. Here, 29 is a rotating knob for rotating the blade holder 1. An elastic spring piece 15d is provided on the mounting base rotation part of the rotating plate 15.
has a click portion 15e that engages with a convex super 26b provided on the striped mounting base 26, and has a function of generating a click when the blade holder 1 is rotated. The rear surface 27 of the cylindrical mount 26 and the blade holder 1 is a sloped surface that is inclined at a certain angle with respect to the upper surface of the blade mount 11. By rotating the blade holder 1, the cylindrical mount 26 The angle between the outer surface of the fixed blade 16 and the trimmer blade of the movable blade 17 can be freely adjusted within the range of Qo to 8o. Click part 15e
When it crosses one of the protrusions 26b of the pair of protrusions 26b at different 180o positions, it is Qo and the other protrusion 2
6b is 80, and in this state, the blade holder 1 is held stationary by a small external force.
Further, when the click part 15e does not engage with the protrusion 26b, the blade holder 1 rotates with a small external force, but in this state, the Qo
The angle of the trimmer blade can be adjusted freely between ~3o. The blade holder 1 is then rotated to adjust the angle of the cutting edge of the trimmer blade of the movable blade 17, which is composed of a fixed blade 16 and a movable blade 17, depending on the purpose of use. That is, the 10th
The angle of the trimmer blade can be adjusted so that the electric shaver body A can be easily used when shaving armpit hair as shown in Figure a or when shaving leg hair as shown in Figure 10B. Further, when cleaning, the male thread 28 and the female thread 12 are unscrewed and the cutting blade block C is removed. As described above, the present invention includes a comb-shaped fixed blade and a comb-shaped movable blade that reciprocates with the fixed blade and protrudes from the outer peripheral edge of a substantially cylindrical blade holder, and has a drive source inside for driving the movable blade. There is a sloped surface between the electric shaver body and the blade holder that are in sliding contact with each other, and the blade holder is attached to the electric shaver body so as to be rotatable around the center of the electric shaver body, so that the blade holder can be rotated. By moving the trimmer blade, the angle of the cutting edge of the trimmer blade consisting of a fixed blade and a movable blade can be changed, and the angle of the trimmer blade can be changed to an angle that is convenient for shaving the hands, legs, armpits, etc.
