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.

Abstract: The present invention provides an electrically driven toothbrush, which comprises a hollow handle, an electrical assembly module in electrical connection with a pair of spring and a cap member. The hollow handle includes a first end provided with a tooth brushing portion and a second end provided with an opening. The electrical assembly module in electrical connection with the spring is inserted into the hollow handle through the opening. The cap member is removably attached to the hollow handle through and closes the opening. By bending the cap member, two spring coils of the pair of spring make contact with each other so as to conduct an electrical path to the electrical assembly module for turning on the electrically driven toothbrush structure. By designing the proposed structure of the present invention, it successfully achieves the purpose of improving and enhancing the conveniences of use for users.

Abstract: A swing-triggered flashing toothbrush comprises a hollow brush handle having a movement space; a transparent patterned layer formed on the surface of the hollow brush handle and having a press button and an operable grip coupled to the press button; a control circuit board arranged inside the hollow brush handle, and a metallic ball arranged inside the operable grip. The press button controls the operable grip to hold the metallic ball or release the metallic ball to the movement space. Once the metallic ball is released, a swing movement drives the metallic ball to hit the interior of an electric-connection chute of the control circuit board. Thus, the control circuit board is triggered to control a battery assembly to power light emitting elements. Thereby, the light emitting elements project light outwards through the transparent patterned layer.
