An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

A system and method for providing variable power is disclosed. The system includes a power supply which provides power to at least one instrument. A pedal comprises a variable resistor that is configured to produce a resistance value within a predetermined range based on an amount of pressure which is being applied to the pedal. The voltage being supplied to the instrument is varied in accordance with the resistance value produced at the pedal.

Disclosed is a portable teeth cleaning apparatus, which implements, through a pump in a teeth cleaner, a function of supplementing a teeth cleaning liquid from a connecting seat connected to the teeth cleaner. Therefore, it is no longer necessary to connect the teeth cleaner to a teeth cleaning liquid source through a connecting hose during teeth cleaning, and liquid leakage is avoided during liquid supplement. Further, a seating/unseating status and whether a liquid reservoir is filled up are detected automatically, and a controller controls on/off and switching of a series of valves, thereby implementing automatic liquid supplement of the teeth cleaner.

A method and apparatus permitting arbitrary, relative motions of a distal end of a toothbrush or flosser with respect to a handle with real-time selectable motions. The toothbrush has a handle and a post, with a mechanism mechanically coupling the handle to the post permitting relative translational movement of the post with respect to the handle.

The present invention relates to an electric or motorized toothbrush. The toothbrush contains a brush head having bristles that rotate in either a clockwise or counterclockwise direction in a non-oscillating manner. An elongated handle contains a motor, rechargeable batteries and a rotatable shaft to rotate the bristles in a desired direction. The bristles are rotated using manual control buttons disposed on the handle. Typically, a clockwise rotation is performed for cleaning top teeth and a counterclockwise rotation is performed for cleaning bottom teeth. The toothbrush enables users to change the brush direction for top and bottom teeth without having to switch hands.

An oral cavity cleaning device, which comprises a body, a water jet tip, a first motor, a second motor, a brush, and a water suction assembly. A rotating shaft extends out of an upper end surface of the body. The first motor drives the rotating shaft to vibrate to drive the brush to vibrate. The upper end surface of the body further comprises a water outlet, and the water jet tip is disposed on the upper end surface of the body and is in communication with the water outlet. Further, the water jet tip is disposed on a side of the brush facing a user, and the water jet tip is disposed below bristles of the brush. The second motor drives the water suction assembly to pump water from a built-in or external container, and water from a water passage disposed in the body sprays out of the water outlet and the water jet tip.

In one embodiment, a charging connector for charging devices, such as oral health devices, is disclosed. The charging connector may include a cable configured to connect to a power source and a plug in electrical communication with the cable and configured to connect to a device. The plug includes a plug body, a first conductive contact in electrical communication with the cable, a second conductive contact in electrical communication with the cable, a first magnetic element aligned with the first conductive contact and having a first polarity, and a second magnetic element aligned with the second conductive contact and having a second polarity that is different from the first polarity.

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.

A charger for charging a rechargeable energy source of a personal care device has a housing having a charging region for positioning the personal care device, a circuit for performing a charging procedure of the rechargeable energy source of the personal care device, a motion sensor for detecting a motion of at least a portion of the charger, preferably wherein the charger comprises a motion enhancer, a controller coupled with the charging circuit and the motion sensor. The controller is arranged to activate the charging circuit when the controller receives a motion signal from the motion sensor indicating a placement of the personal care device in the charging region and/or to deactivate the charging circuit when the controller receives a motion signal from the motion sensor indicating a removal of the personal care device from the charging region.
