Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric razor for a shaving head that has arched outer blades arranged side by side and that floats up and down.

[0002]

2. Description of the Related Art Conventionally, shaving heads for electric razors having arch-shaped outer blades arranged side by side are those that move up and down independently, one that moves up and down around a point, and one that moves up and down by a link mechanism. There is a case where the shaving head rotates in one direction, and one in which the shaving head is raised with one point as a fulcrum by the skin pressure of the one shaving head is devised.

[0003]

The electric razor required is early shaving, deep shaving, comfort, ease of use, skin-friendly, etc. In order to satisfy these conditions, the two-head system is generally used. It is necessary to apply the head to the skin at a certain angle in order to efficiently capture the skin, and it may be difficult to shave because the person applies the head differently.
Conventionally, in order to solve it, there are one in which a head is independently lifted up and down, one in which a head is moved up and down by a link mechanism around one point, and one in which a head is rotated around an axis.
In the case where the head rises and falls independently, when shaking the body against the skin or tilting or shaving the inclined skin,
In some cases, strong pressure was applied to the inner head, making smooth shaving impossible. Further, when shaving slanted skin, there is a problem that the outer head adheres slowly and one head easily separates, and one head moves up and down around one point and one head rotates around one point. Since one head is raised by using one point as a fulcrum due to the skin pressure of the head, there is a problem that it cannot move independently and lacks agility. The present invention has been made in view of the above problems, and an object of the present invention is to quickly sense the skin pressure applied to one head so that one head floats above the skin pressure amount. Makes the skin stick to the skin at an appropriate angle, so that you can shave quickly to wastelessly shave, and you can shave deeply by stretching your skin. It is to provide an electric razor that can efficiently and smoothly shave against the skin.

[0004]

[Means for Solving the Problems] In order to achieve the purpose,
In the electric shaver of the present invention, the housing (10)

a, 2a) with one or more head levitation stops (4, 5) on the upper and lower straight track lines (7 ', 8'), and one or more balance plates on the outer holder (11) or inner holder (12). (3) One or more balance plate levitation stoppers (6) allow the shaving heads (A, B) to freely swing vertically by the action of the levitation energy (E) so that the shaving heads (A, B) can float up and down. Head levitation stoppers (4) and (5) are provided at a position intermediate between the head levitation stop (4) and the limit levitation point by horizontally controlling the levitation by the balance arms (3a, 3b) of the balance plate (3). ) And (5) or the balance plate levitation stop (6) are separable from the balance plate (3), and the balance plate (3) is connected to the balance arms (3a) and (3).
The surface (3c, 3d) for suppressing the flying of the head floating stoppers (4) and (5) by b) is formed in a slidable V in a straight line or an arc shape, and is provided at both ends of the shaving head (A, B), Outer blade frames (1a, 2a) are formed in an arc shape, are supported by an inner holder (12) so that they can float in an arc, and head levitation stoppers (4, 5) are provided on arc track lines (7 ", 8"). By doing so, the adhesion of the head to the skin can be further improved.

[0005]

Since the above-mentioned measures are taken, the balance plate 3 accumulating the levitation energy E of the shaving heads A and B keeps the heads balanced on average, and the skin pressure applied to one head is quickly detected. The balance is broken and the V-cut surfaces 3c and 3d of the balance plate 3 raise one head above the skin pressure amount, and the head is brought into close contact with the skin at an appropriate angle on average, thereby quickly shaving to wastelessly shave However, by stretching the skin, a deep shave can be made, and if a certain amount of skin pressure is applied to both heads, the head levitation stopper separates from the balance plate and floats independently.
