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.

A drivetrain assembly (100) for a personal care device (10), the drivetrain assembly including a primary resonator (110); a secondary resonator (140) configured to reduce vibrations transmitted from the motor to a body (12) of the personal care device; a fixed point (130) positioned between the primary resonator and the secondary resonator; a first spring member (120) connected at a first end to the primary resonator and at a second end to the fixed point; a second spring member (150) connected at a first end to the secondary resonator and at a second end to the fixed point; a coupling spring (160) connected at a first end to the primary resonator and at a second end to the secondary resonator; and an actuator (170) configured to exert force on at least one of the primary resonator and the secondary resonator.

An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin eccentrically connected to the drive shaft, and a driven shaft having a second rotary axis and mounted in the housing for a pivoting movement. The driven shaft is coupled to the drive pin by a gear mechanism converting a rotary motion of the drive shaft into the reciprocating pivoting of the driven shaft. The gear mechanism has first and second transmission stages, the former including a cross slider, and the latter an elastically deformable transmission member. The cross slider has a sliding support extending perpendicular to the first rotary axis and receiving the drive pin. The cross slider is axially guided in the housing to move in an axial direction perpendicular to the first rotary axis and perpendicular to the extension of the sliding support. A link, offset relative to the second rotary axis, connects the cross slider to the elastically deformable transmission member.

A drive train assembly (22) for an oral care device (10) having a housing (12), comprising: a plurality of elongated leaf springs (50) symmetrically disposed around the circumference of the drive train assembly, each of the plurality of elongated leaf springs secured at both ends; and a ring (46) encircling the plurality of elongated leaf springs, wherein the ring is fixedly connected to each of the plurality of elongated leaf spring assemblies and fixedly connected to the housing of the oral care device.

A dental device includes a mouthpiece configured to sit against occlusal surfaces of a patient's teeth and a motor connected to the mouthpiece. The motor is configured to vibrate the mouthpiece at a frequency between 60 and 120 Hz and an acceleration between 0.03G and 0.06G such that the mouthpiece places an axial vibratory force on the occlusal surfaces.

Provided is a cleaning device for personal cleaning and care, comprising a cleaning device housing detachably connected to a handle housing, a bracket for supporting the cleaning device, a cleaning element carrier and cleaning elements distributed on the cleaning element carrier, a passive assembly, and a cleaning device transducer. The cleaning device transducer comprises at least two transducer elastic elements; one end of each transducer elastic element is fixedly connected to a corresponding transducer elastic element retainer, and the other end of each transducer elastic element is fixedly connected to an transmission arm of the transducer bracket coupling elastic element; wherein a cleaning device having a natural vibration frequency f.sub.natural is constituted utilizing the bending strain of an elastic material, such that the natural frequency f.sub.natural of the cleaning device is in the range of 100 Hz to 400 Hz, and the relationship between the natural frequency f.sub.natural and the frequency f.sub.0 of the electromagnetic force produced by the drive coil in the handle satisfies: 0.85f.sub.0<f.sub.natural<1.05f.sub.0. The present cleaning device has a compact structure and an aesthetically pleasing shape, rotates steadily, and produces little noise.

A toothbrush, including a head portion, a handle portion, a locking mechanism configured to lock said head portion to said handle portion, a capsule including a motor assembly and power supply, the capsule being configured to be received within said handle portion, and at least one communication connection configured to enable said toothbrush to communicate with one or more external computing devices.

A multi-purpose molar lift oral insertion and double level panorama form designed bristle brush tilter provides a thorough oral cleaning for dental and gums. The new invention is a small mechanism apparatus designed for a person with health challenges and advanced pace everyday life.

This new invention designed to help and evolve it's usage for hospital bound, preoperational, concrete operational, formal operational stages. This present invention is also designed to prevent over waste plastics going in marine ocean animals and landfills. The new invention's waste is its replaceable disposable double level panorama form designed bristle brush.

The new invention's main feature part is called the molar gap tilt lift platform. This main feature on the new invention sets in the area where a person's molar lies in the mouth. A typical oral dental jaw anatomy has its molar area in the jaw pattern. The 2nd molar are label as 2, 15, 31, 18 set and the last 3rd molar are label as 1, 16, 32, 17 which also call the wisdom teeth. This present new invention will not perform and work without the designed feature call the molar gap tilt lift platform.

The molar gap tilt lift platform feature is the main important designed to cause a gap or space between to upper and bottom jaw. Then new invention's molar gap tilt lift platform is set in its area between the upper, lower molar. And last the whole oral insertion fully enclosed in mouth. The pivot axle part along with its attached double level bristle brush can parallel on its swivel from the rotate shaft pin by oscillate or maneuver left side to right side or up and down just a touch of the fingertip.
