An electrically operated assembly includes a handle housing and a connector for repeatably attaching and detaching a head to and from the assembly. The connector is in direct proximity to a motor having an eccentric weight. The connector is made from a material having an e-modulus that is higher than an e-modulus of the material from which the handle housing is made. A ratio of an overall length extension of the handle housing extending along a longitudinal housing axis to an overall length extension of the connector extending along a longitudinal connector axis is from about 2.5 to about 4.5, and preferably from about 3.0 to about 3.5.

The present invention relates to an electric or motorized toothbrush. The toothbrush contains a brush head having bristles that rotate in either a clockwise or counterclockwise direction in a non-oscillating manner. An elongated handle contains a motor, rechargeable batteries and a rotatable shaft to rotate the bristles in a desired direction. The bristles are rotated using manual control buttons disposed on the handle. Typically, a clockwise rotation is performed for cleaning top teeth and a counterclockwise rotation is performed for cleaning bottom teeth. The toothbrush enables users to change the brush direction for top and bottom teeth without having to switch hands.

A photosensitive pressure alarm device for electric cleaning care appliances comprises at least one light source, at least one photosensitive unit, a light reflecting surface, a detection circuit, and an alarm portion. The light source and the photosensitive unit are provided on a movable component or a movable component on a same side, and the light reflecting surface is provided on a stationary component or the movable component. Under the combined action of an external force (F.sub.1) and an elastic force (F.sub.2), the light reflecting surface or the light source and the photosensitive unit provided on the movable component can move with the movable component, and the incident angle and the reflection angle of the light on the light reflecting surface change, causing that the light receiving area of the photosensitive unit changes, and in turn resulting in change of the electrical performance of the photosensitive unit.
