An electric toothbrush includes a toothbrush body. The toothbrush body includes a toothbrush head. The toothbrush head includes a handle part, a first platy body disposed below the handle part, and a first brushing sheet and a second brushing sheet disposed side by side and below the first platy body. The lower surface of the first platy body is provided with a first brush bristle, the rear side surface of the first brushing sheet is provided with a second brush bristle, and the front side surface of the second brushing sheet is provided with a third brush bristle.

Embodiments of the present invention comprise a powered toothbrush comprising a bristle head, an outer gear, and a plurality of bristles. Both the bristle head and the outer gear may comprise a distal end, a proximal end, and a center. The distal end of the bristle head may mate with the proximal end of the outer gear. The outer gear may rotate about a first axis of rotation. The mating between the bristle head and the outer gear may cause the bristle head to orbit the first axis of rotation via one or more bristle paths while simultaneously completing one or more rotary movements about a second axis of rotation, which may move along the bristle paths with the bristle head.

A device for cleaning interdental spaces includes a housing that forms a handle. The device also includes a brush holder for holding an interdental brush, and a drive device which is configured to generate rotational and translational movement of the brush holder and/or of an interdental brush held in the brush holder.

The utility model discloses a U-shaped electric toothbrush. The U-shaped electric toothbrush includes a handle and a U-shaped brush head. The U-shaped brush head includes an inner brush piece and an outer brush piece separated from each other. Bristles are provided on opposite surfaces of the inner brush piece and the outer brush piece. A driving device configured to drive the inner brush piece and the outer brush piece to move in a reciprocating and alternating manner is provided on the handle. The driving device includes a motor, a connecting rod, a connecting sleeve sheathed on the connecting rod, and a gear set. The motor drives, through the gear set, the connecting rod and the connecting sleeve to move in a reciprocating and alternating manner in a radial direction of the connecting rod. The outer brush piece is connected to an upper end of the connecting sleeve and is drivable to move by the connecting sleeve. An upper end of the connecting rod passes through the connecting sleeve and protrudes upward. The inner brush piece is connected to the upper end of the connecting rod and is drivable to move by the connecting rod. According to the utility model, the inner brush piece and the outer brush piece are drivable to move in a reciprocating and alternating manner in upward and downward directions in an oral cavity to clean teeth with the bristles. Therefore, the amplitude of motion of the bristles is increased, cleaning efficiency is improved, and the time spent by a user on tooth brushing is shortened.

A toothbrush apparatus and system and associated method. The apparatus includes a sensing module that performs at least one of the following: detect at least one time period associated with use of the toothbrush apparatus, detect one or more movements of the toothbrush apparatus, and any combination thereof. The apparatus's one or more processors communicatively coupled to the sensing module determine one or more measurements based on at least one of: the detected time periods, the detected movements, and any combination thereof, and store the determined measurements in one or more memory locations communicatively coupled to the processors. The apparatus also includes one or more feedback modules that receive the stored measurements and encode the measurements into corresponding feedback signals. One or more data transfer modules transmit the feedback signals.

The invention relates to an electric toothbrush provided with longitudinal, also called axial, oscillating movement that occurs at the active end of the bristle plumes, or nylon filaments, without the end or tip of the brush causing potentially traumatic blows, which represent an undesired risk, as still occurs according to the existing prior art.

A toothbrush (10) includes a brush assembly (16) with at least three bristle arrangements (12), each having opposing inwardly-directed bristles (122, 124, 126) for simultaneously contacting facial and lingual surfaces (52, 54), and preferably also occlusal surfaces (56) of the teeth (50). Flexible linkages (14), interconnecting the bristle arrangements (12), maintain a relative spacing between the bristle arrangements (12) while allowing variation of an effective curvature of the brush assembly (16) such that the bristle arrangements (12) can ride along, and conform to a non-uniform curvature of, the arch of teeth. The toothbrush (IO) preferably also includes an actuation mechanism (22) for generating to-and-fro motion of the brush assembly (16) along the arch of teeth, most preferably combined with a more rapid small-amplitude oscillatory motion.

A three-way mechanical toothbrush includes an angular mechanical toothbrush having a plurality of switches and a charging port disposed on a first end and a toothbrush head disposed on a second end. The toothbrush head provides for three (3) discrete areas of brush bristles with each area capable of multiple directional brushing action.

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.

A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.
