An electric toothbrush device having bristle movement in three dimensions includes an elongate body comprising a neck extending between a handle and a head. A drive shaft engaged to a motor in the handle extends into the head. A plate is engaged to a transfer shaft, which extends perpendicularly from the drive shaft through a planar face of the head and which is operationally engaged to the drive shaft. The plate is external to the head and parallel to the planar face. Bristles are engaged to a second face of the plate. First and second protuberances are engaged to the planar face and the plate, respectively. Movement of the plate parallel to the planar face induced by the transfer shaft brings the second protuberance into contact with the first protuberance to induce repetitive movement of the plate and the bristles in a direction perpendicular to the planar face.

An electric toothbrush, in combination with a universal base for receiving and wirelessly charging the toothbrush, the base to be coupled with the electric toothbrush for wireless communication therebetween. The base comprises a magnetic element for forming a magnetic connection with the electric toothbrush when the latter is received by the base for charging. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

The present invention relates to an electric toothbrush base protector. The protector is in the form of a cover or liner that can be placed on a sink on top of a toothbrush charging unit. The cover eliminates contact of a base of the electric toothbrush with the sink surface and with the top of the charging unit. The material of the cover can be a plastic, a cotton or other material. The cover features a continuous opening that enables the electric toothbrush to be placed on the top surface of the charging base. The cover prevents contamination and enables users to quickly secure and store the toothbrush immediately after use.

A control device for a noncontact power supply device includes a power transmission coil for outputting an alternating magnetic flux upon receiving alternating electric power, and a power transmission control unit for controlling alternating electric power to be supplied to the power transmission coil. The power transmission control unit includes a first mode and a second mode. The first mode controls the alternating electric power to be supplied to the power transmission coil in order to transmit electric power, to be supplied to a load of a power reception device, to a power reception coil, and the second mode controls the alternating electric power for supplying electric power less than the electric power transmitted by the first mode to the power transmission coil. After being activated, the power transmission control unit selects initially the first mode.

The general field of the disclosure herein relates to the design of one or more health related monitoring or maintenance devices. These devices may include but are not limited to devices that monitor and/or maintain the health of users or devices that monitor and/or maintain the health of assets. The devices include oral cleaning devices for maintaining and monitoring the oral health of users, clothing for monitoring the health and fitness of users 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.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system does not include an external on/off switch or any remote on/off switching mechanism. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

A brush includes a head with bristles, an actuator that expands and contracts in accordance with an electric signal, a connection member that transmits vibration of the actuator to the head, and a body including a housing that houses the actuator. The direction of reciprocal vibration of the head is at a predetermined angle relative to the direction of extension of the housing.

An electric toothbrush includes a gyro sensor inside a main body. The gyro sensor detects an angular velocity of the main body and the main body includes a head portion, a neck portion, and a grip portion in a longitudinal axis direction. An angle formed by a longitudinal axis of the main body in a state that brush bristles of the head portion contact with a brushing site in a dentition with respect to the longitudinal axis of the main body in a state that the brush bristles of the head portion contact with a reference position in the dentition is obtained, based on an output from the gyro sensor. A corresponding point corresponding to the brushing site on an approximate curve that curves corresponding to the dentition is obtained based on the angle, and coordinates of the corresponding point are used as a translational position of the brushing site.

The present application discloses an electric toothbrush, which relates to the technical field of toiletries, and specifically comprises a body and a toothbrush head, wherein two through holes are integrally formed at an end of an end cover at the front of the body, and two groups of lamp beads are installed on the inner side of the end cover near the top through the lamp control circuit board. The toothbrush head is composed of a sleeve, a central main rod and a vibrator docking unit as a whole, wherein the central main rod and the vibrator docking unit are all made of PMMA high light-transmitting plastic by integral injection molding. The present application improves the design on the basic structure of the existing split-type electric toothbrush, so that it can realize the disinfection and sterilization of each dead corner of the toothbrush head.

Provided are a washing device, a control method thereof and a smart home apparatus. The washing device includes a support plate, a charging cup, a liquid feeder and a power supply management system. A top surface of the support plate is provided with a first charging stand. The heating member can be electrically connected to the first charging stand. The liquid feeder is provided with a fluid inlet, a fluid outlet and an on-off switch. The power supply management system is connected to and controls the first charging stand and the on-off switch, the power supply management system receives a start-up instruction, controls the on-off switch to be turned on according to the start-up instruction to supply liquid to the charging cup, and controls the first charging stand to be electrified according to the start-up instruction to heat the liquid in the charging cup through the heating member.
