An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

An oral hygiene device in the form of a toothbrush 10 comprises a handle section 12, a cartridge 14 containing a cleaning composition held under gas pressure, an actuating mechanism 16 and a head section 18. The cartridge has a discharge opening at a front end thereof, which includes a control valve 26 comprising a valve stem 27. The actuating mechanism 16 includes a plunger 40 and a lever formation 38 which acts on the plunger. The lever formation is acted upon by a hand-operated actuating button 58 for dispensing the plunger rearwardly for depressing the valve stem 27 for releasing cleaning composition from the cartridge causing the cleaning composition to be conveyed under gas pressure along passage 48 of the valve stem and into passages 46, 32, 37 and 29 where it is discharged via opening 31 at a distal end of the head section 18 onto bristles 28.

A dental cleaning system (2) comprising a holder (12) for dental floss (18), which includes two mutually spaced brackets (19) and dental floss (18) held between the two brackets (19), and an, in particular U-shaped or annular, base body (1) to be slid onto a finger, which includes a recess (4) situated in the longitudinal direction (3) of the base body (1) for accommodating a fingertip. Essentially, the brackets (19) extend transversely to the longitudinal direction (3) of the base body (1). A first grip surface (9) is situated at least on each of the two sides of the base body (1), which is provided for controlling the movement of dental floss (18) in the mouth with the aid of the fingers adjacent to the base body (1). An appropriate base body (1) comprises, at least on each of the two sides of the base body (1), a first grip surface (9), which is provided for controlling the movement of dental cleaning elements, in particular dental floss (18), in the mouth with the aid of the fingers adjacent to the base body (1). An appropriate holder (12) for dental floss (18) comprises a second part (20) of a form-locking and/or force-locked fastening system (14) to be accommodated in a base body

An interdental instrument may include a handling section (handle) for manual gripping of the interdental instrument, a carrier held by the handling section, on which an interdental part (e.g. a flossette or an abrasive element) is arranged, a joint device for pivotally holding the carrier on the handling section, so that the carrier can be pivoted relative to the handling section about a pivot axis between at least two mutually angularly offset holding positions. The joint device may include two mutually opposite sliding guide surfaces which are formed on the carrier side and/or handling section side, where the pivot axis crosses the sliding guide surfaces and may be being perpendicular to the two sliding guide surfaces.

A dental floss insertion device for inserting an end of a length of dental floss into an enclosed oral space. The device may include a body and a tip attached to the body and cooperating with the body to define a floss guide path. A first roller may be positioned on a first side of the guide path and a second roller may be positioned on a second side of the guide path. The second roller may be moveable toward and away from the first roller to open and close a nip that receives the length of floss, thereby allowing a user to apply a compressive force on a piece of floss located between the first and second rollers while simultaneously rolling the second roller to advancing the end of the length of floss along the guide path, through the distal orifice, and into an enclosed oral space.

An oral hygiene system including a head with a base portion with arms extending to support a gum sweep and flossing filament. The system may include removeable heads with different configurations directed to different oral environments and uses.

An adjustable flossing tool includes a tool body having a major tool axis and a headstock. At least one string positioner having first and second positioner arms is positioned on the headstock. A floss string extends from the first positioner arm to the second positioner arm of each string positioner. Adjustment can be made to position the first string in a first string position in parallel to or at an angle to the major tool axis. Adjustment can also be made to position the first string to a second string position, the second string position being different from the first string position relative to the major tool axis.

The present disclosure relates to a multifunctional visual oral cleaning instrument that includes multiple functions of: a visual dental floss, and/or visual oral forceps, and/or a visual oral irrigator, and/or a visual toothbrush, and/or a detachable visual interdental brush. The dental floss, and/or oral forceps, and/or oral irrigator, and/or toothbrush, and/or interdental brush are/is connected with an oral viewer through a connecting mechanism. In one aspect, a visual oral irrigator includes an oral irrigator, an oral viewer, and a connecting mechanism. The oral irrigator is mounted on the oral viewer through the connecting mechanism. The oral viewer further includes a housing, a power supply system, a lighting system, a viewing system, a circuit system, and a switch.

The present disclosure relates to a multifunctional visual oral cleaning instrument which includes multiple functions of a visual dental floss, and/or visual oral forceps, and/or a visual oral irrigator, and/or a visual toothbrush, and/or a detachable visual interdental brush, and the like. The dental floss, and/or oral forceps, and/or oral irrigator, and/or toothbrush, and/or interdental brush are/is connected with an oral viewer through a connecting mechanism. By using a smartphone or tablet computer, the dental floss, oral forceps, oral irrigator, toothbrush or interdental brush and the gap between teeth can be clearly seen, so that the tooth gaps can be conveniently cleaned and treated under direct vision during use, and the cleaning effect of the tooth gaps can be viewed and recorded in real time.

Luminous dental floss of the present application includes dental floss, an illumination system, and a handle. The dental floss is detachably connected to the handle. The illumination system includes a light source system, a circuit system, a switch, and a power supply system. The light source system is connected to the power supply system through the circuit system. The circuit system and the power supply system are mounted in the handle, and the switch is mounted on the handle. Illumination light emitted by the light source system can illuminate an oral cavity, and especially an observation window is designed on the luminous dental floss of the present application. During use, under the illumination of the illumination system, a process of the dental floss entering a gap between teeth can be directly observed, thereby facilitating cleaning and effectively avoiding accidental injury to gingivae.
