Replaceable head electric toothbrush and connection structure therefor

An electric toothbrush includes a head having a moving portion, a handle, and shaft between the head and the handle. A body portion is hollow and further includes a motor operative to generate motion for driving the moving portion. A battery is located within the hollow section for powering the motor. A first switch, operatively connected to the motor provides momentary operation of the toothbrush. Optionally, a second switch provides for continuous operation of the toothbrush. The first switch can be operated while the toothbrush is in a toothbrush package, such as, for example, a plastic blister pack. A consumer can momentarily observe the operation of the toothbrush before purchasing the toothbrush. The consumer cannot operate the second switch and is thereby prevented from leaving the toothbrush in a battery draining operational mode for extended periods of time.

The first aperture extends from the top section first end along a length of the top section within the top section. The second aperture is located along a top surface of the top section, a bottom section having a first end and a second end. The first end includes a tabbed portion which matingly engages with the notched portion of the top section first end. The bottom section further includes an extension having a first end and a second end and a protrusion adjacent the extension first end wherein the extension is connected to the bottom section first end. The protrusion selectively cooperates with the second aperture in the top section to selectively lock and unlock the top and bottom sections. The extension is inserted into the first aperture of the top section. The extension can include a first section and a second section. The protrusion extends from the first section.
