A visual oral scraping spoon of the present application includes an oral scraping spoon, an oral observation instrument and a connecting mechanism. The oral scraping spoon is detachably connected to the oral observation instrument through the connecting mechanism, and under the action of an observation system of the oral observation instrument, the oral scraping spoon can be used to scrape and clean the teeth or the tongue under direct vision, and the cleaning effect can be observed in real time, and the cleaning process can be shot and photographed. Furthermore, the oral observation instrument may also be provided with a flusher, the flusher is used in conjunction with the oral scraping spoon to thoroughly flush the removed dental calculus, dental plaque, coated tongue and the like in time, and the using process is more comfortable, convenient and efficient.

An oral care device such as an oral care implement or a toothbrush. The oral care device may include a handle and a head. The head may have a plurality of cleaning elements extending therefrom. The head may comprise a channel and a plurality of electrodes may be located within the channel. The electrodes may be coupled to a power source. The electrodes may be used to generate a chemical agent via the application of an electrical potential across the electrodes when in communication with an electrolyte. The chemical agents may include ozone, hydrogen peroxide, peroxide, chlorine hypochlorite, ions, peroxides, and/or other chemical agents.

Attachment assemblies for oral hygiene devices and, in particular, attachment assemblies having improved designs to more effectively clean an individual's tongue or other inter-oral surface are described herein. These improved attachment assembly correspond, amongst other aspects, to improved fluid chamber configurations, improved fluid channel configurations, improved fluid exit hole configurations, improved air inlet hole configuration, and air channel features. Furthermore, these improvements to attachment assemblies are capable of being implemented separately from, or in combination with, one another.

An oral care implement having a head with a soft tissue cleanser thereon. In one aspect, the invention can be an oral care implement including a handle and a head coupled to the handle, the head comprising a front surface; a rear surface opposite the front surface; a peripheral surface extending between the rear surface and the front surface; a first elastomeric soft tissue cleanser comprising a bumper portion that extends along the peripheral surface, the bumper portion comprising an undulating upper edge that includes a plurality of high points protruding above the rear surface and a plurality of low points located at or below the rear surface; and a plurality of tooth cleaning elements extending from the front surface.

A tongue brush includes bristles that emanate from a front surface of the head of the tongue brush and a tongue scraper that emanates from the opposing rear surface of the head of the tongue brush. These bristles can include tongue brush bristles as well as tufted bristles. The tongue brush bristles may be arranged in a first region of the front surface separately from the tufted bristles. The tongue scraper can extend in an opposite direction and from an opposing surface from the bristles.

An ergonomic handle to be used in conjunction with a hand-operated personal use tool. A unique feature of the ergonomic handle is a series of concave-shaped grooves and convex-shaped protrusions on the top surface and one concave-shaped groove and two convex-shaped protrusions on the bottom surface. The ergonomic handle has an arcuate shape to facilitate a secure grasping of the handle by the fingers of one handle.

An oral cleaning device for a baby is disclosed herein. The oral cleaning device includes a head portion, the head portion including one of: (i) at least one plurality of bristles for brushing gums and/or teeth of a baby, or (ii) at least one protrusion for scraping food particles and other matter from a tongue of the baby; and a body portion connected to the head portion, the body portion having a first end that is distal from the head portion and a second end that is proximal to the head portion, the first end being oppositely disposed relative to the second end, the body portion including a tapered finger recess for accommodating varying finger sizes of different users, the tapered finger recess having a cross-sectional area that gradually decreases in size from the first end to the second end.

A personal hygiene device has a resonant motor and a motor control unit for applying a periodic voltage signal with a driving frequency at the resonant motor for driving the resonant motor into an oscillating motion with an oscillating frequency equal to the driving frequency. The motor control unit comprises a synthesizer circuit for digitally synthesizing the periodic voltage signal from voltage pulses of variable length provided with a pulse frequency higher than the driving frequency such that at least two voltage pulses are applied at least in one of two half cycles of each period of the periodic voltage signal.
