This invention relates to novel oral care devices that are based upon alternated magnetic polarity magnetic elements built into oral care devices, which provide very effective removal oral plaque, tooth tartar and oral bacteria.

A skincare device having energy regenerating end effector is presented. In one embodiment, an end effector includes an inner end effector structure configured to oscillate about a first axis. The inner end effector structure includes at least one magnet and a plurality of contacting elements configured to contact skin of a user. The end effector also includes an outer end effector structure comprising at least one induction coil. The at least one magnet and the at least one induction coil cooperate to generate electrical current in the at least one induction coil when the end effector structure oscillates about an axis.

A vibration reduction assembly (200) including: (i) a shaft (240); (ii) a first component (210) positioned along the shaft and having a first face (212) comprising a plurality of magnets (230) positioned to alternate between a magnet having a first magnetic pole (232) at the first face and a magnet having the opposite magnetic pole (234) at the first face; and (iii) a second component (220) positioned along the shaft and having a first face (222) comprising a plurality of ferromagnetic extensions (260), wherein the first face of the first component is separated from the first face of the second component by a gap (280) having an adjustable first distance, and wherein a pair of the plurality of magnets interact via magnetic force with a respective one of the ferromagnetic extensions to reduce vibrations from a drivetrain to a housing portion of the personal care device.

The present invention provides personalized experience based on the skin condition of each user. A cosmetic device according to the embodiments of the present application includes: a detachable component including a magnetic portion, a magnetic sensor for outputting a signal depending on magnetism of the magnetic portion, and a control circuit for driving the component by controlling a motor depending on the signal.

Disclosed herein is an accommodation case for an electric toothbrush, as an accommodation case for an electric toothbrush for storing an electric toothbrush having an electric body and a brush head detachably coupled to the electric body, including a first housing and a second housing connected to each other and configured to accommodate the electric toothbrush, wherein the first and second housings are formed to have a length for accommodating at least a portion of the brush head and only a portion of the electric body and exposing the rest of the electric body, and the first housing includes a counteracting portion generating a counter moment against a rotational moment generated by the rest of the electric body, while the electric toothbrush is accommodated in the first housing.

The disclosures herein relate to the design of one or more battery monitoring or maintenance devices in some embodiments including guidance for autonomous vehicles for recharging, service or replacement of batteries or related devices. These devices may include but are not limited to devices that monitor and/or maintain the health of batteries or related devices that monitor and/or maintain the health of assets. The devices include batteries for vehicles, oral cleaning devices, smart-clothing with integrated batteries and sensors and charging pads which may monitor the health or assets being charged. Sensors may be integrated in these devices including but not limited to IMUs, thermocouples or oral cleaning devices, IMUs in clothing like shoes or wrist bands, or timers or charging sensors in magnetic surfaces which may cause one or more objects and/or other magnetic surfaces to float when a desired function is achieved.

A detachable hair brush apparatus is disclosed. The hair brush apparatus may comprise a handle with elongated metal extension rods at one end and at least one hollow brush head for insertion around the metal extension rods. In a locked position, the metal extension rods extend substantially through a base of the brush head. At least one button may be located on said handle for releasing the mechanical locking engagement. Torque provided by a user of the hair brush apparatus is absorbed by the metal extension rods of the hair brush handle. In this way, functional separation of two distinct systems is provided for, namely the function of attaching and the function of absorbing torque. This will make for increased robustness of each system. In a preferred embodiment, neither the handle nor the at least one hollow brush head comprises a magnet for coupling.

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 brush with magnetic filaments is described. The brush may be used, for example, as a brush for applying a cosmetic material. The filaments of the brush may, in one example, be made of a synthetic material infused with magnetic material.
