Abstract

An engaging structure of an electric shaver and an electric charger is provided wherein the electric charger at least serving to charge the electric shaver is mounted thereat. The engaging structure includes a magnet provided at one of the electric shaver or the electric charger; and an attracting member provided at the other thereof, the attracting member being made of a material magnetically attracted to the magnet. Further, a contact portions for electrically connecting the electric shaver and the electric charger are provided between a weight center of the electric shaver and the magnet disposed above the contact point at an opposite side of a mounting direction of the electric shaver.

Claims

1. An engaging structure of an electric shaver and an electric charger, the electric charger at least serving to charge the electric shaver mounted thereat, comprising:

a magnet provided at one of the electric shaver or and the electric charger; and

an attracting member provided at the other of the electric shaver and the electric charger, the attracting member being made of a material magnetically attracted to the magnet,

wherein contact portions for electrically connecting the electric shaver and the electric charger are provided between a weight center of the electric shaver and the magnet disposed above the contact portions at an opposite side of a mounting direction of the electric shaver.

2. The engaging structure of an electric shaver and an electric charger of claim 1, wherein the magnet is provided at the electric charger and a central position of the attracting member is deviated, slightly above a central position of the magnet, in a direction allowing the electric shaver to be attached along the mounting direction in the electric charger.

3. The engaging structure of an electric shaver and an electric charger of claim 1, wherein among the contact portions, a contact portion of a contact metal strip provided at the electric charger has a hemispherical shape.

4. The engaging structure of an electric shaver and an electric charger of claim 1, further comprising a multi-point bender for varying a reaction force acting at the contact portions in two or more steps.

5. The engaging structure of an electric shaver and an electric charger of claim 3, further comprising a detector unit provided separately from the contact metal strip provided at the electric charger, the detector unit detecting the electric shaver when the electric shaver is mounted in the electric charger.

6. The engaging structure of an electric shaver and an electric charger of claim 1, wherein the magnet is provided at the electric shaver and a central position of the attracting member is deviated with respect to a central position of the magnet, in a direction allowing the electric shaver to be attached along the mounting direction in the electric charger.

7. The engaging structure of an electric shaver and an electric charger of claim 5, wherein the detector unit has a shaver detection switch that is switched on by being pressed by the electric shaver when the electric shaver is mounted in the electric charger.

8. The engaging structure of an electric shaver and an electric charger of claim 6, wherein the magnet is provided at the electric shaver and a central position of the attracting member is deviated slightly above a central position of the magnet, in a direction allowing the electric shaver to be attached along the mounting direction in the electric charger.

9. The engaging structure of an electric shaver and an electric charger of claim 6, wherein the magnet is provided at the electric shaver and a central position of the attracting member is deviated slightly below a central position of the magnet, in a direction allowing the electric shaver to be attached along the mounting direction in the electric charger.
