A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. Magnets, connected respectively to the piston and the drive, enable the drive to couple to the piston and move it within the fluid chamber to draw fluid into the fluid chamber. A stop prevents the piston from being pulled beyond a stop position so that through continued actuation of the drive the magnets separate to allow a spring to push the piston away from the stop position to urge a burst of fluid from the fluid chamber.

A capsule integrated with a nail polish applying element for usage by a nail polish application apparatus comprising a capsule compartment and a pressure applying element, the capsule comprising a container defining a reservoir containing nail polish fluid, the container comprising an upper face with an opening sealed with a sliding gasket and a bottom face, wherein a volume of the reservoir is reduced and an internal pressure is built in the reservoir when pressure application slides the sliding gasket towards the bottom face, and a container housing comprising a body portion shaped to receive and accommodate the container, one or more conveying tunnels having a proximal end mechanically fixated to a bottom side of the body portion and a nail polish applying element mounted to receive the nail polish fluid from a distal end of the conveying tunnel(s) for applying the nail polish fluid on a nail surface.

A mathematical calculator, and a method of using the same, is disclosed which can help people, particularly children, to easily learn and master multiplication operations. The mathematical calculator comprises a substantially cylindrical platform, and in accordance with a first embodiment, the multiplicands and multipliers are located within a plurality of columns and rows defined upon a plurality of adjacent wheels which are rotatable around a longitudinal axis of the platform, whereas in accordance with a second embodiment, the multiplicands and multipliers are located within a plurality of columns and rows which are defined upon a solid block.

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

A flow-modulating toothbrush device and relative processes for conserving potable water are introduced. It comprises a brush-head member and neck portion, connecting with a body-handle member for maneuvering the device in the process of brushing the teeth. An insertable reservoir facility provides a water source. An ancillary conduction tube facility having alternative means for channeling water directly from a sink faucet into the device. Water in the reservoir facility is pressurized for means of subsequent flows through conduction tube members. A flow activation technique urges the water from the containment facility to the brush-head member. Due to flow modulation, and known, predetermined, water-volume requirements in brushing one's teeth, only a modicum of potable water is withdrawn in the process; this is the minus withdrawal allotment factor of the device. Being generally employed, the device would conserve vast volumes of potable water globally, affecting electrical energy, drought conditions, hydrology, and climate.

The present invention provides a reusable toothbrush with a replaceable toothpaste cartridge, which allows the replacement of the cartridge (3) after the entire quantity of the toothpaste has been exhausted, so that the toothbrush does not need to be disposed of. Additionally, its bristle (20) is protected from contamination before usage by means of a cap (4), while the hardening of toothpaste is prevented. The present invention has two distinct functions, namely the extraction of fluid from the replaceable toothpaste cartridge (3) and resetting the device before the replacement of the replaceable toothpaste cartridge (3). The toothbrush comprises a toothbrush handle (1) intended to carry said bristle (20) and membrane (21), the latter being removably attached to a hollow shank (19), and which houses the replaceable toothpaste cartridge (3) and the mechanism for extracting toothpaste from the replaceable cartridge (3), which can be reset in order to replace the replaceable cartridge (3).

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.

Disclosed is an oral care device that includes a body and a base connected to the body. The oral care device includes a mouthpiece extending from the base and an oral care product reservoir in communication with the mouthpiece. A plurality of brushing walls extend from the base about the mouthpiece.

Disclosed is a device which combines makeup product reservoirs and makeup brushes into one tool.
