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.

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.

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.

An applicator device for applying a fluid to an object has a hollow body, an applicator, a sensor, and a notification system. The hollow body stores the fluid therein. The applicator discharges the fluid. The sensor is configured to detect a fluid surface of the fluid. The notification system is configured to generate a notification signal based on a detection signal from the sensor.

A smart electric toothbrush showing the results of brushing by determining the brushing posture, which includes a brush handle and a brush head mounted on the brush handle, a motor in the brush head driving the brush head to work, and a controlling component electrically connected to the motor. A posture detection unit is located in the brush head electrically connected to the controlling component, and the posture detection unit includes a three-axis gyroscope and a three-axis accelerometer. Roll and pitch angles of the smart electric toothbrush are detected by the posture detection unit, and a brushing section is determined by the controlling component by detecting a posture of brushing after complementary filtering the roll angle and the pitch angle. By matching the determined position to the 16 sections, the user can be alarmed that which section is missing or over-brushing.

A pressure feedback system continuously monitors the level of pressure or force on a brush head and is programmed to provide a feedback signal to a user based on the amount of pressure. The pressure level is monitored as a function of the change in the speed of the drive shaft. The system includes a housing, a motor, a drive shaft for attachment to a brush head, a feedback device, a sensor capable of detecting a change in the rotational speed of the drive shaft, and a microprocessor. The microprocessor is programmed activate the feedback device as a function of the measured change in rotational speed. The sensor may be a Hall effect sensor, or another sensor that is responsive to a magnetic field. A magnet may be positioned on the drive shaft, or another portion of the system that moves as a function of the drive shaft.

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.

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.

An oral care appliance having a housing, the housing having a first end, a second end that is at least partially transparent, and a cavity. The cavity having a light source and a light-diffusing fiber optically coupled to the light source and arranged within the second end of the housing wherein the light-diffusing fiber is arranged to produce a first light visible through the second end of the housing.

A toothbrush device is disclosed comprising a motion sensor for sensing motion of the device to produce motion data and a signal analysis unit for analysing the motion data to produce brushing data. A light communication module is arranged to transmit the brushing data to an external device using a light source. This can allow the brushing data to be transmitted without the need to provide a radio frequency transmission module and/or using a light source which also provides visual feedback to the user. The external device may comprise a camera arranged to produce image data, and a processor arranged to process an image of the light source to obtain the brushing data.
