The subject of the present disclosure is an electric toothbrush having a head part with a rotating working element and equipped with technical means to drive the working element and to change the direction of its rotating movement.

An electric toothbrush includes a body part provided with an electric toothbrush head, and a cover part detachably coupled to the electric toothbrush head to sterilize the electric toothbrush head, and the body part is provided with contact type power output terminals to supply a power to the cover part. By including the cover part for sterilization configured to receive a power from a body part of the electric toothbrush with being coupled to the body part of the electric toothbrush, the electric toothbrush allows a user to perform sterilization treatment on the electric toothbrush by coupling the cover part to the body part after use of the electric toothbrush without a need to purchase a separate device for sterilization and carry the same, as well as allowing the user to easily perform hygiene management of the electric.

A saliva collection and testing system comprising an electric toothbrush (1) suitable for taking a user's saliva by way of taking means (15), and a test unit (21) for testing the taken saliva, said test unit (21) including a seat (22) for the electric toothbrush (1) comprising means (25, 33) for taking the saliva collected by the toothbrush, said test unit (21) cleaning-up the saliva taking means (15) of the electric toothbrush (1) after saliva is taken so as to prepare said electric toothbrush (1) to a subsequent use. A digital tooth fingerprint sensor is present on the toothbrush and allows to recognize the user. Advantageously the test results are sent to a remote unit via a wireless system and in an encrypted mode for their subsequent processing by one or several Machine Learning algorithms which exploit an Artificial Intelligence.

The present invention is concerned with an electric utility brush having a flexible drive shaft, and in particular an electric toothbrush having a substantially spherical head mounted on the flexible drive shaft and which can be driven rotationally in at least two different orientations in order to provide comprehensive brushing capabilities.

The present invention is concerned with an electric utility brush having a flexible drive shaft, and in particular an electric toothbrush having a substantially spherical head mounted on the flexible drive shaft and which can be driven rotationally in at least two different orientations in order to provide comprehensive brushing capabilities.

An electric utility brush with a dynamic brush head which has a rotatable head which is capable of undergoing rotation about two separate axes in order to effect multiple modes of brushing.

An electric toothbrush of the present invention includes: a case having first and second drive shafts exposed therefrom, the first and second drive shafts being rotated in opposite directions and moved forward and backward respectively by a drive unit which is driven by a motor; first and second toothbrush bodies coupled to the first and second drive shafts by first and second coupling units respectively, so as to transmit the rotational force and forward and backward motions of the first and second drive shafts; a brush installed at the ends of the first and second toothbrush bodies so as to clean teeth by the rotational force and forward and backward motions transmitted to the first and second toothbrush bodies; and a third toothbrush body having an auxiliary brush, which is coupled to a third drive shaft of the drive unit installed in the case.
