A toothbrush apparatus and system and associated method. The apparatus includes a sensing module that performs at least one of the following: detect at least one time period associated with use of the toothbrush apparatus, detect one or more movements of the toothbrush apparatus, and any combination thereof. The apparatus's one or more processors communicatively coupled to the sensing module determine one or more measurements based on at least one of: the detected time periods, the detected movements, and any combination thereof, and store the determined measurements in one or more memory locations communicatively coupled to the processors. The apparatus also includes one or more feedback modules that receive the stored measurements and encode the measurements into corresponding feedback signals. One or more data transfer modules transmit the feedback signals.

Automatic toothbrushes are disclosed herein. A toothbrush configured in accordance with embodiments of the present technology can include, for example, a handle and a mouthguard coupled to the handle. The mouthguard can be configured to be positioned within a mouth of a user over multiple teeth of the user. A brush assembly having a plurality of bristles can be removably positioned within the mouthguard for engaging and cleaning the teeth of the user. A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

An electrical toothbrush system, device, method and kit are disclosed herein. In some embodiments, the system or device or kit include a suction lumen. In some embodiments, a display-control circuitry is provided, the circuitry configured to cause the display assembly to operate in the first or second display modes according to an elapsed-time-since-most-recent-operation, as measured by the timing circuitry.

A customizable cleaning brush, including a main body, a plurality of head members removably connected to at least a portion of the main body to brush, scrub, and massage a body of a user, a plurality of operation controls disposed on at least a portion of a first side of the main body to perform at least one of a rotation, oscillation, and vibration of the plurality of head members, and a plurality of pressure controls disposed on at least a portion of a second side of the main body to perform at least one of a speed control and a pressure control of the plurality of head members.

There is provided a light guiding unit (10) for use in an oral cleaning device. The light guiding unit is configured to be coupled to a light source (50), and the light guiding unit comprises a homogenizing component (110) having a length along which light from the light source is guided. The homogenizing component is further configured such that at least one of an amount of refraction of the guided light and an amount of internal reflection of the guided light varies along the length to homogenize, along the length of the homogenizing component, an amount of light transmitting out of the homogenizing component.

The present disclosure provides an electric toothbrush including a driving module, a connection shaft, a battery supporter, a support cover, a print circuit board and a switch. The driving module includes a driving element, a driving element supporter, a reset elastic element and a stress element. The connection shaft passes through the driving element supporter and the battery supporter. The driving element is used to drive the driving module to rotate from a starting position to a triggering position and make the reset elastic element generate elastic deformation. In the starting position, the driving element supporter is separated from the switch, and the switch is in an OFF state. In the triggering position, the driving element supporter contacts the switch and the switch is in an ON state, and the driving module rotates to the starting position with a reset force of the elastic deformation of the elastic element.

A personal care device has a hollow housing having at least a first transparent or translucent portion extending between the housing's outer and inner surfaces, a carrier fixed inside the housing, at least a first light source mounted on the carrier, and a light barrier mounted on the carrier. The light barrier has at least a first spring arranged to bias a light barrier plate of the light barrier against the housing's inner surface. The light barrier plate has at least a first light transmission portion that is aligned with the first light source and the first transparent or translucent portion of the housing, so that light emitted by the first light source is visible at the outer surface of the first transparent or translucent portion.

A new and improved helical band actuator (HBA) is provided with a closed conduit upon a radially innermost edge portion of its first elongated fastening band that can accommodate electrical power wiring, as well as fiber optic cables, such that electrical power and computer control data can be transmitted from an electrical power source (EPS) and a central processing unit (CPU) to a powered component supported upon a load-bearing platform being elevated or raised by the new and improved helical band actuator (HBA).

A toothbrush can include a handle and a head. At least one bristle can be attached to the head. The toothbrush can also have an illumination member, an illumination circuit and an activation device. A pliant base on the handle can be used to activate the activation device to initiate the illumination circuit.

A personal care appliance having a brush head assembly, the brush head assembly including a neck having a first end and a second end, a brush head arranged proximate the first end of the neck. The brush head including a first face fixedly secured to a plurality of bristles, the plurality of bristles arranged to extend from the first face in a first direction, and a second face arranged to create a first frictional force between the second face and an oral environment in a second direction, and create a second frictional force between the second face and the oral environment in a third direction.
