A dental cleaning appliance includes a fluid reservoir for storing working fluid, a nozzle for delivering working fluid to the teeth of a user, a light source for illuminating the fluid reservoir and a control circuit for activating the light source to generate an alert which is conveyed to the user through the illumination of the fluid reservoir.

A skincare device includes a brushhead including a marking disposed on a surface of the brushhead, the marking including a shape and a color; a body including a motor assembly configured to oscillate the brushhead; and a first optical encoder configured to detect the marking and determine an identity of the brushhead.

A method includes determining a position of a skincare device with respect to a body part of a user via one or more sensors on the skincare device, the skincare device configured to apply a treatment to the user's body part; obtaining a location of a target area on the body part having a condition for application of the treatment; adjusting a parameter of the skincare device according to the location of the target area and based on the condition.

A skincare device includes a brushhead; a body including a motor assembly configured to oscillate the brushhead and an inertial measuring unit (IMU) configured to determine kinematic measurements of the device; a first optical encoder including a light source and an optical sensor configured to capture images; and processing circuitry configured to determine a location of the brushhead with respect to a body part of the user based on a combination of data measured from the IMU and the first optical encoder.

An interdental brush device comprising an interdental brush including a working part and a connector; a delivery component including a guide head, a sliding mechanism including a sliding block and an interdental brush connecting mechanism, and a housing; the interdental brush comprises a working part with fiber or a protrusion and a connector; the interdental brush is positioned within a bended tube, and the connector of the interdental brush is detachably coupled to the interdental brush connecting mechanism such that lateral movement of the sliding mechanism drives the working part of the interdental brush to slide within the bended tube, the protrusion is made of elastic polymer material, and the connector and the protrusion are formed into a whole; and the sliding mechanism is configured to make the working part of the interdental brush extend from the outlet of the bended tube at the end of the guide head.

An apparatus for removing blackheads and providing skin care treatments comprising a funnel body that comprises a compartment, a first opening and a second opening that are bended about 45 degrees from an axial axis. The first opening further comprises a vacuum tip that is detachable and the second opening further comprises a massage metal plate. The apparatus further comprises a vacuum pump, a CPU, and a PCB. The vacuum tip further comprises a vacuum filter. The funnel body further comprises a smart switch disposed on the outside wall thereof. The apparatus further comprises a lithium battery. The funnel body further comprises vent pores. The apparatus further comprises a status light made of LED.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irradiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.

An electric toothbrush includes a grip portion, a brush portion on which a replaceable toothbrush is mounted, and an illumination ring between the grip portion and the brush portion. The illumination ring is provided around the toothbrush as an annular structure so that a user can view the illumination ring no matter what angle he/she is holding the toothbrush.

An oral care system includes an oral care implement and a smart device removably retained in a cavity of the oral care implement. The smart device may have a plurality of sensors for sensing conditions of the oral cavity and/or for sensing various parameters associated with the movement of the oral care implement within the oral cavity during use. The smart device may also include a transmitter for transmitting data/information obtained by the sensors to an electronic device, such as a smart phone.

Oral hygiene monitoring system is disclosed to track motion and orientation of an oral hygiene device. The control system may process data output from a motion sensor to determine position and orientation of an oral hygiene device with respect to a user's mouth. In some examples, the system may use machine learning techniques to identify position and orientation, brush stroke type, and other specific actions.
