摘要： A toothbrush provides a head with bristles, a neck and a handle. An eccentrically rotational weight is engaged for rotation with a motor. The motor and weight are disposed within the handle. The handle, neck and head each have a different intensity of vibration. The toothbrush houses an electrical circuit, which includes a processor and at least two LEDs (light emitting diodes) at least one of which illuminates the neck and optionally also the head and the ends of the bristles attached to the head. At least two of the LEDs in the circuit are capable of emitting different colored light with respect to each other. The at least two LEDs are switched on for a predetermined time in a predetermined sequence under the control of the processor.

摘要： A mouth-containing toothbrush includes a housing, a first tooth-brushing module assembly and a rotary drive assembly. The housing has a groove for containing teeth. The groove has a first inner groove face, a second inner groove face, and a bottom face connected between the first inner groove face and the second inner groove face. The first tooth-brushing component is used for cleaning surfaces of the teeth, and the first tooth-brushing component includes a brush body shaft and bristles arranged on an outer circumference of the brush body shaft. The brush body shaft is rotatably arranged between at least one of the first inner groove face and the second inner groove face and the teeth, and the brush body shaft extends along an extension direction of the groove. The rotary drive assembly is used to drive rotation of the brush body shaft.

摘要： 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.

摘要： A personal hygiene device includes a vibrator housed in a handle. A shaft is coupled to the vibrator and extends from the vibrator to a brush head. The shaft is electrically conducting and includes one or more proximal electrical contacts in electrical contact with an electrical source and one or more distal electrical contacts in electrical contact with one or more electrical elements located in the brush head. The shaft is configured to transfer vibrational energy created by the vibrator to the brush head to vibrate the brush head.

摘要： An oral care system for a defined oral care cleaning cycle comprising a base module 100, a head module 150 comprising a toothbrush-bristle brush 165 disposed on a bristle-retaining surface of the head module, and a tail module 151. A multi-input/multi-display counter 149 is disposed on a base-module main body 110 of the main body 100. The multi-input/multi-display counter 149 independently displays first and second count-states, and includes first and second independently-operable user inputs that are respectively associated with the first and second count-states such that: (a) in response to user engagement of the first user input, the first count state is incremented or decremented; and (b) in response to user engagement of the second user input, the second count state is incremented or decremented.

摘要： An oral care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having a transverse through hole defined by an upper surface and a lower surface. A first electrode and a second electrode are located on the head and operably coupled to a power source to have opposite electrical charges. At least one of the first and second electrodes may be located on one of the upper and lower surfaces of the transverse through hole. In some embodiments, the first electrode is located on the upper surface of the transverse through hole and the second electrode is located on the lower surface of the transverse through hole.

摘要： A personal hygiene device has a resonant motor and a motor control unit for applying a periodic voltage signal with a driving frequency at the resonant motor for driving the resonant motor into an oscillating motion with an oscillating frequency equal to the driving frequency. The motor control unit comprises a synthesizer circuit for digitally synthesizing the periodic voltage signal from voltage pulses of variable length provided with a pulse frequency higher than the driving frequency such that at least two voltage pulses are applied at least in one of two half cycles of each period of the periodic voltage signal.

摘要： A head module capable of reciprocal rotation for an electric cleaning apparatus comprises cleaning elements, a housing and a driven rod disposed in a hollow inner cavity of the housing, wherein the rod is provided with a hollow cavity body for accommodating a drive shaft; at least one gap is provided in a region surrounding the hollow cavity body; at least one inner side notch is distributed on a side wall of the inner cavity, for accommodating a protrusion; the rod further comprises a partially cylindrical or conical cavity body region. When the drive shaft is not yet inserted into the rod, there is a gap between the notch and the protrusion in a direction perpendicular to the rotation axis (L1) of the drive shaft. The length of the gap is greater than or equal to the amount of single-side interference between the rod and the drive shaft.
