According to the oral care device of the present disclosure, a flushing flow path can be reasonably arranged, an overall volume of the oral care device is reduced, it is convenient for a user to operate, and use comfort of the user is improved.

The present application provides an integrated oral care apparatus, including: an uneven housing, a composite member, a medium supply unit, a vector generation unit and a medium delivery member, where the uneven housing has a main extension line and oppositely arranged first end and second end, the main extension line extends from the first end of the uneven housing to the second end of the uneven housing, the vector generation unit connects with the composite member through a vector transmission rod, the vector transmission rod has a medium conveying channel, and the first end of the medium conveying channel is communicated with the composite member; the medium delivery member is configured to bridge between the vector generation unit and the medium supply unit, and has a communication channel, and the communication channel is hermetically coupled between the second end of the medium conveying channel and the medium supply unit.

The present disclosure provides an oral care device. The oral care device includes a handle part and a care head part; the handle part includes: a sonic motor including a motor body and a power output shaft, a fluid mechanism provided with a fluid inlet and a fluid outlet, and a housing including a machine mounting part and a water storage cavity. By using the oral care device provided by the present disclosure, the reasonable layout of a rinsing flow path can be achieved, the overall size of the oral care device can be reduced, it is convenient for a user to perform an operation, and the comfort level provided for a user during use can be improved.

A power toothbrush having a vibration compensation system, the toothbrush including a toothbrush housing (72), and an actuator which includes a stator (74) having a first moment of inertia and a rotor (76) having a second moment of inertia, at the end of said rotor is mounted a bristle member. A first spring element (86) having a first spring constant connects the stator to the housing, while a second spring element (88) having a second spring constant connects the rotor to the housing, wherein the ratio of the first and second spring constants is substantially the same as the ratio of the first and second moments of inertia.

An oral device for checking a time to go to a dentist. The oral device includes a pH sensor configured to measure pH within an oral cavity, a housing on which the pH sensor is mounted, a processor configured to analyze measured pH from the pH sensor, and a wireless communication unit functionally connected to the processor and configured to perform communication with an external device. The oral device is useful for a patient who needs continuous management such as an implant surgery patient by allowing the patient to visually and easily check a time to go to a dentist and an individual oral condition of the patient. Further, by allowing the user to simply check the condition of the oral cavity at home, it is possible to more effectively manage the condition of the teeth and to save medical expenses.

A personal hygiene device has a drive unit, an energy storage, such as a rechargeable battery, a determination unit for repeatedly or constantly determining an energy storage level of the energy storage, and a control unit arranged for providing energy from the energy storage at the drive unit during an on state of the device and for gradually reducing the energy level from a nominal energy level to a first reduced energy level during a first energy level reduction time period when the determined energy storage level has fallen below a first energy storage level threshold but is above a second energy storage level threshold and for continuing provision of the first reduced energy level while the device stays in an on state and the determined energy storage level stays above the second energy storage level threshold.

According to one aspect, an electric toothbrush may include a handle, a brush head, a rechargeable battery, an electric motor, and a pair of electrical contacts. The handle may have a first end region and a second end region defining a longitudinal axis therebetween, the handle defining a volume from the first end region to the second end region. The brush head may include bristles, the brush head releasably securable to the first end region of the handle. The rechargeable battery may be in the volume. The electric motor may be at least partially disposed in the volume, the electric motor in electrical communication with the rechargeable battery, the electric motor in mechanical communication with the brush head. The pair of electrical contacts may be in electrical communication with the rechargeable battery, and the pair of electrical contacts axially and radially spaced from one another, relative to the longitudinal axis.

A vibrating toothbrush is provided with vibration-isolating zones that substantially isolate vibrations in the head and reduce vibrations transmitted to the handle without sacrificing structural integrity around the vibration-isolation zones. Such zones may generally comprise neck material that is reduced in cross-section, thinned, replaced by dampening material, or removed altogether to create transmission-inhibiting voids. The vibration-isolating zones may be further supported by the housing of the vibratory element to maintain the structural integrity around the zones and to thereby alleviate weakness conditions that might subject the toothbrush to fatigue and breakage.
