It consists of a case B having a bottomed cylindrical shape that is screwed and constitutes a lower part, and a cylindrical transparent case C that is fitted above the case B and constitutes an upper part. Reference numeral 11 denotes a storage portion formed on the upper surface of the case B, which stores and holds a plurality of electric toothbrushes 1 together with the case C. Reference numeral 12 denotes a mountain-shaped protrusion formed in the substantially central portion of the storage portion 11, and 13
Is a ring-shaped 1 provided so as to surround the storage portion 11.
The secondary charging coil, 14 is arranged below the storage unit 11,
An inverter circuit for driving the secondary charging coil 13 at a high frequency,
Reference numeral 15 is an AC cord that is connected to a commercial power source and supplies power to the inverter circuit 14.

この充電電流によって二次電池６が充電される。The charging operation of the electric toothbrush 1 according to the present invention will be described below with reference to FIGS. 3 and 4. AC
When the cord 15 is connected to a commercial power source and the inverter circuit 14 is started, the inverter circuit 14 is connected to the primary side charging coil 1
3 is driven at high frequency. Along with this, a high-frequency magnetic field is generated around the primary-side charging coil 13 as shown by magnetic force lines in FIG. In this state, the electric toothbrush 1 becomes the charging stand 1
When the secondary charging coil 5 is inserted into the storage unit 11 and is housed in the storage unit 11, the secondary charging coil 5 is positioned within the area of the high frequency magnetic field generated by the primary charging coil 13 and the primary charging coil 13 To generate a charging current in the secondary charging coil 5.
The secondary battery 6 is charged by this charging current.

は十分な充電電流を発生する。Here, as shown in FIG. 3, the magnetic flux density of the high frequency magnetic field generated around the primary side charging coil 13 is very weak in the substantially central portion of the accommodating portion 11, so that the secondary battery 6 can be stored sufficiently. There is a possibility that the charging current required to fully charge the secondary side charging coil 5 may not be generated. Therefore, in the present invention, as described above, the mountain-shaped protrusion 12 is formed substantially in the center of the storage portion 11. Therefore, the bottom portion of the electric toothbrush 1 inserted in the charging stand 1 is positioned around the storage portion 11 so as to be guided by the mountain-shaped protrusion 12. In other words, the secondary charging coil 5 of the electric toothbrush 1 is located in the vicinity of the primary charging coil 13, that is, in the region where the magnetic flux density of the high frequency magnetic field generated in the primary charging coil 13 is sufficiently strong. This means that the secondary charging coil 5
Generates sufficient charging current.
