Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shaver equipped with an inner cutter rotated by a motor and an outer cutter with which the inner cutter comes into sliding contact. The purpose is to achieve thinner electric shavers by forming

In conventional electric shavers, an inner blade support is attached to the rotating shaft protruding from the center of the motor, an inner blade is attached to the inner blade support, and an inner blade is attached to the outer blade, which is curved into a dish shape, to maintain strength. Generally, the blades are in sliding contact. In such conventional electric shavers, only the peripheral edge of the outer blade is fixed to the housing and is curved into a dish shape to maintain strength, so the electric shaver is thick as a whole due to the dish shape and is portable. There were some inconvenient drawbacks.

The present invention has been made in view of these drawbacks.
The present invention will be described below with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a disc-shaped stator fixed via a housing 2, and is composed of a permanent magnet. A shaft 12 passes through the center of the stator 1 and is fixed thereto. Reference numeral 3 designates a yoke plate consisting of a top plate portion 3a and a circumferential body portion 3b, and is pivotally connected to the shaft 2 via a bearing 4 fixed to the center of the top plate portion 3a for rotation. A rotor 5 is fixed to the circumferential body portion 3b of the yoke plate 3 and is formed of a coil, and is arranged so as to surround the stator 1 inwardly. Reference numeral 6 denotes a top plate commutator fixed to the surface of the top plate portion 3a, with which brushes 7, 7 fixed via the stator 1 are in sliding contact. Reference numerals 8, 8, . . . are inner cutters attached to the upper surface of the top plate portion 3a of the yoke plate 3, and are preferably able to float via a spring.
Reference numeral 9 denotes an outer cutter having a circular plate-like surface that touches the skin and has a large number of hair introduction holes, the central part of which is supported by the shaft 12, and the peripheral part of which is detachably attached to the housing 2 via a threaded tube 10. Fixed. The blades 8, 8 are in sliding contact with the outer blade 9. A battery 11 is housed in the housing 2 and serves as a power source for driving the motor.

As described above, in the electric shaver of the present invention, the motor is configured as a so-called outer rotor and the shaft is fixed, so that it can be configured to support the center of the outer cutter, and therefore, even if the outer cutter is formed into a flat plate shape, it does not touch the skin. It has become possible to maintain sufficient strength to withstand force, and the electric shaver has been made thinner, making it possible to provide an electric shaver that is convenient for carrying.
