Abstract

An electrically driven toothbrush is provided, comprising a hollow handle having a first end provided with a tooth brushing portion and a second end provided with an opening. An electrical assembly module is inserted into the hollow handle through the opening and provides power to turn on the toothbrush. A conductive elastic piece is fitted with the electrical assembly module and contacts with an electrical fixture. A cap member is removably attached to the hollow handle for encapsulation. At least one trigger portion is provided on one side of the cap member. When the trigger portion contacts with the conductive elastic piece, the conductive elastic piece deforms and touches with the electrical fixture to form an electrical loop with the electrical assembly module to generate power for turning on the proposed toothbrush. By designing above, it successfully achieves purposes of improving and enhancing the conveniences of use for users.
