A cartridge and a base unit for use in an oral care appliance are disclosed. The cartridge includes a connection interface configured to form a detachable connection. The base unit is also configured to engage operatively with the cartridge to facilitate flow of an oral care composition from the cartridge into the oral care appliance.

The invention relates to shaving systems containing a handle and replaceable cartridges and allowing a liquid to be supplied to the skin of the user during use. A shaving system comprises a handle (1) having an internal channel (2) for passing liquid; an adapter head (3) on the proximal end of the handle (1), having a slot-type channel (4) which communicates with the channel (2) of the handle (1); a cartridge holder (5) in the form of a floating arm which has an internal slot-type channel (6) and is disposed on the proximal end of the head (3), said slot-type channel communicating with the slot-type channel (4) of the head (3); a replaceable cartridge (7) and an adapter (8) connected to a liquid supply and having an internal channel (9) for passing liquid. The connections between adapter (8) and handle (1), handle (1) and head (3), and head (3) and cartridge holder (5) are made detachable by means of a pin/plug connection. The result is an improved quality of shaving and rinsing of the shaver, as well as reduced design complexity.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. The fluid reservoir includes a fluid port from which fluid is dispensed from the fluid reservoir, and through which the fluid reservoir is replenished. The fluid reservoir is moveable between a first position in which the fluid port is connected to the fluid delivery system, and a second position in which the fluid port is exposed to allow the fluid reservoir to be replenished. Magnetic forces urge the fluid reservoir towards its first position.

A portable toothbrush having an internal water source that allows a user to brush his or her teeth while away from a bathroom or other external water source. The portable toothbrush has an internal water source for dispensing water into a user's mouth and a storage receptable for suctioning waste or rinse water from the user's mouth back into the storage receptacle for disposal after use. The toothbrush may have the toothpaste impregnated on the toothbrush head or the toothpaste may be contained in refillable receptacle as a part of the toothbrush head. The toothbrush of the present invention can be automatic (electric motor or pump) or manual. The toothbrush can be a one-time use toothbrush or multiple-use.

The invention relates to a dentifrice dispenser for dispensing a dentifrice onto a J-shaped or U-shaped mouthpiece configured for simultaneously encompassing and cleaning a plurality of dental positions with the dispensed dentifrice and with cleaning elements provided on or in the mouthpiece. The dispenser comprises a dispenser duct work having an inlet and a manifold. The manifold comprises a multiple of outlet openings configured for dispensing dentifrice. The duct work is configured for passing dentifrice from the inlet to the outlet openings. The outlet openings are distributed along a J-shaped or U-shaped curvature and debouch towards and/or along the curvature, which matches at least part of a dental arch such that the outlet openings can dispense dentifrice simultaneously on a multiple of locations along the curvature, the multiple of locations corresponding to the multiple of outlet openings.

Methods, systems, and products monitor a person's regimen for medicinal and dietary restrictions. When the person's regimen requires a liquid medication or supplement, an oral instrument is commanded to dispense a dosage of fluid. The oral instrument stores a reservoir of the fluid. If the oral instrument is a spoon, for example, the spoon may automatically dispense cough syrup or other medicine. A toothbrush, likewise, may automatically dispense mouthwash. A sensor may confirm presence of the oral instrument in the person's mouth, thus ensuring the dosage of fluid is ingested.

An electric toothbrush that detects plaque on the teeth, ensures accurate plaque detection, and performs cleaning of plaque. The electric toothbrush may include a body having a gripping part and a stem with a brush unit detachably coupled to the body. The electric toothbrush may include a light emitting element for emitting light onto the tooth and a light receiving element for receiving light that reflects off of the tooth. A controller may be included to determine an amount of plaque on the tooth based on the amount of reflected light detected. The electric toothbrush may also include a fluid dispensing system that dispenses fluid based on the amount of reflected light detected. In some aspects, the electric toothbrush may operate in multiple oscillation modes, and it may only dispense fluid in some of the modes but not all of the modes.

A toothbrush with fluid directing drive assembly is provided. The toothbrush may include a handle including an end surface, a brush shaft extending from the end surface of the handle, a drive assembly positioned within the handle and causing the brush shaft to oscillate upon actuation of a motor, a brush tip removably coupled to the brush shaft and positioned adjacent to the end surface of the handle, and a fluid passage defined within the drive assembly within the handle. The brush tip may include a fluid conduit therein. Oscillation of the brush shaft may cause the entire brush tip to oscillate correspondingly. Fluid may be transported through the drive assembly and to the fluid conduit of the brush tip by the fluid passage.

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

In one aspect, the present invention relates to an oral health dental product dispensing toothbrush configured to selectively spray an oral health dental product directly into a user's mouth during use of the toothbrush and configured to selectively spray the oral health dental product directly onto bristles of a brush head in order to disinfect and/or sanitize the bristles. The oral health dental product is sprayed into the user's mouth and onto the brush bristles in a controlled manner and in the form of a fine, gentle, dispersed mist. In another aspect, the present invention relates to an oral health system including one or more of the toothbrushes according to the first aspect and one or more oral health dental products for use with the one or more toothbrushes.
