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 attachment brush part for an electrical body care brush, in particular an electrical toothbrush, wherein the attachment brush part is designed in a multi-part manner. The attachment brush part includes an attachment brush housing, a drive rod for driving a brush head, with a brush-head-side end section, on which a first toothing is arranged, and with a hand-part-side end section, and furthermore a brush head with a bristle carrier and care bristles which are arranged on this, wherein the bristle carrier includes a second toothing. The attachment brush housing further includes a securing element for the rotatable mounting of the hand-part-side end section of the drive rod. The first and second toothing form a drive toothing for the driving of the brush head by the drive rod.

For many years people have been great need of an oral cleaning device that cleans thoroughly, quickly, and efficiently. In designing my Teethsweep-T electric toothbrush all of these factors and more were addressed and remitted. This hand held cleaning device reduces the average brushing time by more than fifty percent. My Unique Sequential Alignment of Gears, found in no other electric toothbush, allows for the individual three hundred sixty (360) rotation of four individual circular sets of bristles. Other electric oral cleaning devices uses sonic motion or pulse with bristles moving up and down; and side to side when in operation. While dentists recommended brushing in a circular motion, My Teethsweep-T electric toothbrush uses circular motion for thorough cleaning when in operation.

The present invention discloses a system and method related to the field of dentistry, specifically dental appliances such as retainers, dentures, grills and athletic mouth-wear and is proposed to provide advanced assembly in providing assistance in cleaning the appliances through improved measures. Currently, there are cleaning methods for retainers and dentures, however they only include liquid solution methods without automatic moving bristles. As per the present art, users soak their retainers or dentures in the solution and then are required to use a toothbrush to scrub off excess liquid solution or built-up plaque that was not dissolved by the solution, making the process too repetitive and time consuming. Additionally, the toothbrush does not provide automatic circular motion, which is preferred in order to produce retainers or dentures that are plaque-free and completely transparent. Finally, appliances can be damaged and break when using a handheld technique with a toothbrush due to lack of support and stability for the appliance. This cleaning device takes into consideration these deficiencies and corrects them to make the process more effective and convenient for all users in any environment.

An angled-head rotary cleaning device for dental purposes includes a plastic housing having an elongated neck portion that defines a sleeve with a wall. The neck portion includes a first end and a second end. The plastic housing has a head portion coupled to the first end of the neck portion and angled relative to the neck portion. The cleaning device also includes an elongated light guiding element having a light entry portion to receive light, and a light exit portion to emit light. At least a portion of the light guiding element is accommodated within the wall of the neck portion.

A brush head is provided on the front surface at a distal-end-side part of a neck of a replaceable brush. A fitting shaft portion is provided on a planting base of the brush head so as to protrude rearward and penetrate through a support wall portion of the neck. A shaft hole is formed at a rotation center of a brush head body of the brush head so as to extend frontward from a rear surface of the brush head body. The neck has ahead support shaft mounted to the shaft hole so as to rotatably support the brush head. A front end of the head support shaft is located frontward of a rear surface of the planting base, and power from the driving portion is transmitted to a rear part of the fitting shaft portion.

An electric toothbrush is disclosed herein. The electric toothbrush may include an elongated body portion with opposed first and second ends and a longitudinal axis extending therebetween; a brush head section arrangeable toward the first end and including: a first bristle support member rotatable in a first direction, and a second bristle support member coupled to the first bristle support member and rotatable in a second direction about a centrally defined axis, the second direction being opposite the first direction; and a drive rod coupled to at least the first bristle support member and having an axis oriented so as to extend coincident with, or substantially parallel to, the longitudinal axis of the electric toothbrush, the drive rod being arranged to linearly move along the axis so as to rotate the first bristle support member in the first direction and rotate the second bristle support member in the second direction.

An oral care system comprising: a. an electrical motor b. a base assembly comprising: i. an elongated base-assembly main body defining an elongate axis; and/or ii. a battery or a battery compartment optionally including electrical contacts for a battery, the battery and/or the battery compartment being electrically wired to the electrical motor; and c. a head assembly is disclosed herein. Methods and kits are also disclosed.

A head structure of a brush appliance comprises a frame movably connected with a head driving shaft, driving bristle retainers connected with and driven by the head driving shaft, and driven bristle retainers which and the driving bristle retainers are alternatively arranged with each other. In the head structure, the driven bristle retainers are driven by the driving bristle retainers from the frame in a constrained mode and move around a respective motion axis. The driving bristle retainers have protrusions. The driven bristle retainers have bevel surfaces which correspondingly cooperate with the protrusions. At least one driven point on at least one of bevel surfaces is closer to the driving bristle retainers than a contact point or a contact line or a contact surface of the at least bevel surface and the corresponding protrusions. Thereby the driven bristle retainers are driven by the driving bristle retainers in the moving process.

A linear motor is disclosed. The linear motor includes an armature mounted for driven linear oscillation substantially along a longitudinal direction; a secondary mass mounted for linear oscillation substantially along the longitudinal direction; and a coupling unit for coupling the armature and the secondary mass. The coupling unit includes at least two coupling spring assemblies and at least a coupling element, the coupling spring assemblies being arranged in planes perpendicular to the longitudinal direction and being spaced apart from each other, and the coupling element being fixedly connected with the coupling spring assemblies.
