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.

An actuator (52) for a personal care appliance (50) comprises a housing (54), a spindle (64), a tangential actuator portion (70), and an axial actuator portion (72). The tangential actuator portion (70) includes first and second magnet and pole assemblies (76,78) that define a tangential spring function of the tangential actuator portion. The axial actuator portion (72) includes third and fourth magnet and pole assemblies (90,92) that define an axial spring function of the axial actuator portion. At least one of (i) the first and second magnet and pole assemblies (76,78) of the tangential actuator portion (70) and (ii) third and fourth magnet and pole assemblies (90,92) of the axial actuator portion are configured to enhance a corresponding spring function of the axial actuator portion or tangential actuator portion, respectively.

A powered toothbrush head that, in one embodiment, includes a head portion including a first movable tuft block configured for holding tooth cleaning elements. The first movable tuft block is operably connected to a motor-driven drift shaft for movement. An eccentric cam formed on the shaft drives the first movable tuft block via engagement with a slot formed in the body of the first movable tuft block. The first movable tuft block is movable in a combination oscillating motion comprising vertical motion and lateral pivoting or tilting motion upon rotation of the drive shaft. A related method for oscillating the first movable tuft block is disclosed.

A power toothbrush apparatus may include a body having a cavity and an opening leading to the cavity. An electric motor may be situated within the cavity and may include first and second biasing members; a stator casing situated between, and linearly biased by, the first and second biasing members, the stator casing may further include at least one opening and at least one electromagnet to generate a magnetic field; and a rotor which may have opposed ends and which may extend through the at least one opening of the stator casing, the rotor may further include an output shaft. The power toothbrush may further include a workpiece having a brush head coupled thereto and which may be coupled to one of the opposed ends of the output shaft.

An interdental cleaning member includes a brush having a plurality of bristles, each of the plurality of bristles comprising a bristle shaft, the bristle shaft extending from a shaft base to a shaft tip, and formed to have a thickness and resiliency configured to clean interdental areas and areas interposing a tooth and gum tissue surrounding the tooth.

Actuator for a personal care appliance comprising a housing, a spindle, a tangential actuator portion, an axial actuator portion, and a controller. The tangential actuator portion comprises a first magnet and pole assembly having a first sequence of individual grouped magnet segments spaced apart within the housing in a first radial orientation and polarity order, and a first pole assembly of pole members in a first radial configuration about the spindle, a second magnet and pole assembly having a second sequence of individual grouped magnet segments spaced apart within the housing in a second radial orientation and polarity order, and a second pole assembly of pole members in a second radial configuration about the spindle, and an electromagnetic coil disposed about the spindle in-between the first and second magnet and pole assemblies. The tangential actuator portion rotationally displaces the spindle with respect to the housing about a principal axis.

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.

An interdental cleaning member includes a brush having a plurality of bristles, each of the plurality of bristles comprising a bristle shaft, the bristle shaft extending from a shaft base to a shaft tip, and formed to have a thickness and resiliency configured to clean interdental areas and areas interposing a tooth and gum tissue surrounding the tooth.

The present invention relates to a fingertip toothbrush for a pet, and more particularly, to a fingertip toothbrush for a pet that is configured to allow bristles to vibrate and reciprocally slide up and down, so that toothbrushing can be carefully and precisely achieved, which is effective in improving the teeth health of the pet.

This invention provides a toothbrush device comprising: a plurality of bristle tuft assemblies, every the bristle tuft assembly comprises a support member and a bristle tuft, the bottom of which is flexibly configured within the support member; a base, a plurality of assembly holes are configured on the base, support members of the plurality of bristle tuft assemblies are flexibly configured in the plurality of assembly holes respectively; a supportive rotating axis, fixedly connecting with an axis hole in the back of the base and driving the base rotate back and forth; a back shell, a housing chamber matching in size with and accommodating the base is configured on the back shell, the supportive rotating axis is rotationally connected with the back shell. The toothbrush device can more effectively and easily clean the teeth, and different bristle tufts can move independently in different directions in accordance with the irregular surface shapes of teeth so that teeth surface and seams can be much more thoroughly and efficiently cleaned.
