Abstract

The utility model relates to the charging mechanism of an electric toothbrush, comprising an electric toothbrush part and a charging seat part. The electric toothbrush part also comprises a second coil 8. The charging part comprises a charging seat 16 and a first coil 15 which is arranged in the inner cavity of the charging seat 16. The second coil 8 and the first coil 15 are coaxially arranged when the electric toothbrush part and the charging seat part are positioned in the state of charge. After the first coil is powered on, the second coil can have induction current, therefore, the charging seat part and the electric toothbrush part can totally be better sealed, and the electrical apparatus elements in the inner cavity of the electric toothbrush can be furthest protected.

Description

The charging mechanism of electric toothbrush

Technical field

The utility model relates to the charging mechanism of a kind of electric toothbrush, particularly toothbrush.

Background technology

In the prior art, the charging device of electric toothbrush comprises electric toothbrush part and cradle part, and described electric toothbrush partly comprises brush holder at least, be arranged at motor in the described brush holder inner chamber, be arranged at the rechargeable battery in the brush holder inner chamber; Rechargeable battery provides electric power for motor, makes motor rotate.Existing rechargeable battery is the method that adopts the contact charging, promptly the plug by electric toothbrush charges to rechargeable battery with the method that the socket of cradle electrically contacts mutually, because the operational environment of toothbrush is relatively poor, toothbrush often is immersed in water, thus plug, socket to electrically contact the place often fragile.

Summary of the invention

The purpose of this utility model is to provide a kind of charging mechanism of electric toothbrush, and during charging, electric toothbrush part and cradle partly are not electrically connected.

The technical solution of the utility model is: a kind of charging mechanism of electric toothbrush, comprise electric toothbrush part and cradle part, described electric toothbrush partly comprises brush holder at least, be arranged at motor in the described brush holder inner chamber, be arranged at the rechargeable battery in the brush holder inner chamber; Described electric toothbrush part also comprises second coil, described cradle partly comprises cradle, be arranged at first coil in the inner chamber of described cradle, partly be under the charged state in electric toothbrush part and cradle, described second coil, the coaxial setting of first coil, and one of them coil is inserted in another coil.

The utility model compared with prior art has following advantage:

After second coil, the coaxial coincidence of first coil, charging is carried out automatically; After two coils separated, charging stopped automatically, and the effect of two coils is as transformer.Pass to the medium-high frequency alternating current in first coil after, produce the medium-high frequency induced current on second coil, this electric current offers the rechargeable battery charging through handling.Two medium-high frequency induction coil designs that can separate fully make cradle part and electric toothbrush part to seal preferably, can protect motor and circuit in the electric toothbrush inner chamber to damage because of making moist to greatest extent.
