A visual tooth cleaning, grinding and polishing instrument includes a host, an oral observation instrument and a cleaning and polishing tool. The host can drive the cleaning and polishing tool and supply a power source and a control system for an illuminating system, an observation system and the oral observation instrument. A picture shot by a camera of the observation system can be transmitted to a display of the observation system in time, so as to achieve the purposes of cleaning the teeth while observing a process of cleaning the dental calculus, dental plaque and pigmentation on the surface of the teeth with the cleaning and polishing tool and the cleaning effect instantly on a mobile phone, thereby effectively cleaning, grinding and polishing the teeth. A flusher or an electric toothbrush head or other interdental cleaning tools may also be mounted on the host or the oral observation instrument.

Disclosed herein is an oral information management system using a smart toothbrush, the oral information management system including: a smart toothbrush configured to include a camera and at least one sensor; and a user terminal configured to acquire information collected from the smart toothbrush; wherein the user terminal determines the oral health state of a user based on the information collected from the smart toothbrush.

An attachment brush part for an electrical body care brush, in particular an electrical toothbrush, wherein the attachment brush part is designed in a multi-part manner. The attachment brush part includes an attachment brush housing, a drive rod for driving a brush head, with a brush-head-side end section, on which a first toothing is arranged, and with a hand-part-side end section, and furthermore a brush head with a bristle carrier and care bristles which are arranged on this, wherein the bristle carrier includes a second toothing. The attachment brush housing further includes a securing element for the rotatable mounting of the hand-part-side end section of the drive rod. The first and second toothing form a drive toothing for the driving of the brush head by the drive rod.

A toothbrush head, including at least one two-component cleaning element and at least one bristle tuft element, is produced by injection molding. To achieve high design flexibility regarding the arrangement of the two-component cleaning elements and regarding the material choice, the two-component cleaning elements are manufactured separately or in an upstream molding step. Then the two-component cleaning elements, together with the bristle tufts, are over-molded with plastic material, to form the brush head or a part thereof.

The present disclosure relates to an electric toothbrush, and more particularly, to an electric toothbrush including: a main body which includes an outer case; a cleaning body which is coupled to the main body and has a cleaning head formed at one end thereof; a vibration transmission unit which couples the main body and the cleaning body, has a vibration generator mounted thereon to generate vibration, and transmits the vibration to the cleaning body; and a vibration damping unit which is provided between the outer case and the vibration transmission unit, thereby maintaining cleaning performance of the electric toothbrush, reducing magnitude of vibration to be transmitted to a user, and improving convenience for the user.

This document also discloses a member for mounting a toothbrush head to an electric toothbrush. The member includes a base having an opening for receiving a drive shaft of an electric toothbrush. The member also includes a coupling section that includes a cylindrical sidewall that surrounds a cavity for receiving the drive shaft. The member includes a spring in the coupling section. The spring is positioned to transfer vibration from the drive shaft to the toothbrush head when operated.

A connector-housing assembly for an electrically operated personal-care implement comprises a housing defining an inner cavity and a connector for repeatably attaching and detaching a head to and from the assembly. The connector has an overall length extension (Lc) extending along a longitudinal connector axis (Xc), the overall length extension (Lc) being composed of a sub-length (Li) extending within the inner cavity of the housing, and a sub-length (Lo) extending outside of the housing, wherein a ratio (Rc) of the length (Li) extending within the inner cavity of the housing to the length (Lo) extending outside of the housing is from about 1.0 to 1.7, preferably from about 1.0 to about 1.5.

Embodiments presented provide for an oral hygiene apparatus and method of cleaning such that a consumer may effectively clean dental apparatus with a water based solution to prevent recontamination of the oral cavity.

An oral care process which includes initiating a first operational sequence which includes generating an electric potential between a first sacrificial electrode and a second sacrificial electrode, the electric potential in the first operational sequence beginning with one of a first polarity and a second polarity, stopping the first operational sequence, and commencing a second operational sequence which includes generating the electric potential between the first sacrificial electrode and the second sacrificial electrode. The electric potential in the second operational sequence may begin with the other of the first polarity and the second polarity. The electric potential may be alternated between the first polarity and the second polarity at predetermined intervals during at least one of the first operational sequence and the second operational sequence.

A handle for an electrically operated personal-care implement includes a housing having a proximal end and a distal end opposite the proximal end, and an inner cavity. A connector for repeatably attaching and detaching a head to and from the handle is partially accommodated within the inner cavity at the proximal end thereof. A motor, located in the housing's inner cavity, has an eccentric weight. The connector includes a recess accommodating the motor with the eccentric weight.
