A handle for an oral-care implement, the handle comprises an electrical motor arranged to drive an output element structured and configured to couple the handle and a head attachable to and detachable from the handle; and a microcontroller for controlling the motor and to cause the output element to vibrate in (a) at least one oral-hygiene mode during which the oral-care implement is being used for an oral-hygiene routine, wherein the output element is vibrating at a substantially constant frequency, and (b) a disinfection mode during which the handle is being disinfected, before or after being used for the oral-hygiene routine, wherein the output element is continuously vibrating at a modulated frequency alternating within a frequency range of between about 140 Hz and about 250 Hz, for a duration of the disinfection mode.

Handle for oral-care implement for safe and hygienic use by multiple users and method of disinfecting the same

A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

A refill for an electric toothbrush comprises a generally tubular structure formed by refill walls defining an interior space for accepting thereinto a coupling stem of a toothbrush handle. The refill includes a motion transmitter functionally connected to the brush head for driving it. The refill has a coupling device including a pair of mutually opposite and resiliently deformable cantilevered arms disposed in the interior space of the refill and adjacent to the refill walls and extending from respective roots in a circular or semi-circular manner around, and in a plane substantially perpendicular to, the refill's longitudinal axis. Each of the arms is resiliently deformable and terminates with a coupling surface for engaging a coupling pin extending from the handle's coupling stem for secure and disengageable connection therewith.

Refill for electric toothbrush

An electric toothbrush, including a refill connectable to a handle via a coupling device. The handle has a drive mechanism, and the refill has a brush head and a motion transmitter functionally connected to the brush head for driving it. The handle has a coupling stem terminating with a free end and including a coupling pin extending from the stem. The refill includes a generally tubular portion formed by refill walls defining an interior space for accepting the coupling stem of the handle. The coupling device comprises a pair of mutually opposite and resiliently deformable cantilevered arms disposed adjacent to the refill walls in the interior space of the refill. Each of the cantilevered arms terminates with a coupling surface for engaging the stem's coupling pin for secure and disengageable connection between the handle and the refill.

An oral hygiene implement has a neck section extending along a longitudinal direction and a head section having a through hole therein extending through the head section along a through hole direction having an angle with respect to the longitudinal direction and having a head section housing surrounding the through hole. The neck section has a neck section housing surrounding a neck section cavity. The through hole defines a first and a second opening in the head section housing. A cap element, separately made from the head section housing, is connected with the head section housing to essentially cover the first opening. A carrier element, separately made from the head section housing, is arranged to cover the second opening. Between an edge of the first opening and an edge of the cap there is a circumferential gap that allows water, saliva, or toothpaste to escape an interior of the head section during use.
