A touch-control flashing toothbrush comprises a hollow brush handle and a control circuit board. The hollow brush handle has a brush head at one end and a light-permeable handle member at another end. The control circuit board is arranged inside the hollow brush handle and includes a control circuit electrically connected with a light emitting element, two electric-conduction contacts, and a battery assembly. The battery assembly supplies power to the other elements. The electric-conduction contacts are exposed on the surface of the hollow brush handle. Once two electric-conduction contacts are touched simultaneously, voltage of the battery assembly is conducted to the control circuit. Then, the control circuit controls the light emitting element to emit light projecting to exterior through the light-permeable handle member. The touch-control flashing toothbrush is triggered to emit light by touch, interesting children and encouraging them to keep oral health.

A power toothbrush includes a handle having a driving system therein. The driving system is responsive to two drive signals. One drive signal produces a clinically effective cleansing action for the teeth, while the other drive signal is arranged to produce audible sounds from the toothbrush which are cognitively stimulating or relaxing.

The present invention comprises systems and methods for using a specialized styling device, such as a smart hairbrush, smart comb, or accessories, which allow for the collection of data from the devices, and for users to interact over a wireless network. The devices may including a wireless radio frequency modem connected to the internet and a battery to power components, including lights, speakers, cameras, microphones, and sensors. A smart brush may allow for computations through processors, memory, system-on-a-chip, applications, batteries, operating systems, and wired or wireless communication interfaces. It is also possible for the smart brush to connect with other electronic devices, including phones, tablets, and cameras in order to share electrical power and communicate over one or more interfaces. A smart brush may operate as an independent mobile device or within a smart home or other system with multiple computing devices, appliances, and sensors connected together within a network.

A specialized brushing device capable of tracking a user's routine living activities includes an enclosure body comprising a detachable handle with an on/off button, a brush head with a plurality of bristles, and a printed circuit board. The printed circuit board comprises at least one processor, wireless module, memory, graphic content displayed on a screen, haptic vibration module, motion module including at least one accelerometer, antenna, power module, notification indicator, and battery. The memory stores instructions executable by the processor to receive motion sensor detections, store sensor data, analyze the data to generate metadata including time of use, duration of use, and directional information, and generate a report indicating whether usage frequency is below that of a data model. An alert signal is sent to the notification indicator, which activates by light or vibration based on the report. The notification indicator comprises an indicator light, digital display, or haptic vibration module.
