Cleaning devices are provided that have a surface with areas that provide different cleaning states. The areas of different cleaning states are connected to one another by a deflection member that provides tactile and/or audible feedback to the user when transitioning between the different cleaning states.

A personal care device that is capable of two-way communication is provided. In some embodiments, the personal care device operates in a first mode and a second mode depending on whether a signal has been received from a networked computing device, thus allowing a single human-machine interface (HMI) device to both control the personal care device and to cause signals to be sent to the networked computing device. In some embodiments, the personal care device is configured to present media streamed from the networked computing device, and/or to stream audio detected by the personal care device to the networked computing device.

A personal care device (10) configured to generate a feedback signal in response to excessive pressure applied by a user includes: a body portion (12) comprising a first interacting portion (40); a shaft (24) comprising a second interacting portion (42), wherein the shaft and the second interacting portion are moveable, in response to a force applied by the user, from a first position in which the first interacting portion does not physically interact with the second interacting portion, to a second position in which the first interacting portion physically interacts with the second interacting portion; and a sensor (70) configured to detect the physical interaction between the first interacting portion and the second interacting portion, and further configured to activate a feedback signal, in response to the detection of the physical interaction, to the user that excessive pressure is being applied.

Systems and methods for measuring and indicating brush head life are disclosed. In one embodiment, the system includes a brush head that moves with respect to a brush handle; an energy harvester that generates electrical signals based on movements of the brush head; a controller in electrical communication with the energy harvester; and an indicator in electrical communication with the controller. The indicator is energized based on a signal from the controller.

Cleaning devices are provided that have a surface with areas that provide different cleaning states. The areas of different cleaning states are connected to one another by a deflection member that provides tactile and/or audible feedback to the user when transitioning between the different cleaning states.

A comb with a laser function includes a main body, a laser irradiation portion, a vibration portion and a controlling portion. The laser irradiation portion, the vibration portion and the controlling portion are disposed on the main body. The controlling portion is connected to the laser irradiation portion and the vibration portion. The main body includes a brush portion and a handle portion. The brush portion includes a comb tooth portion, and the comb tooth portion includes multiple comb teeth. The laser irradiation portion is adjacent to the comb tooth portion and irradiates a laser beam to a scalp according to the control of the controlling portion. The vibration portion is disposed on the brush portion to generate a vibration according to the control of the controlling portion. The comb with the laser function is capable of irradiating the laser beam to the scalp and massaging the scalp.

An oral care product dispensing system includes a container and a plurality of individually packaged items arranged in an organized fashion according to a predetermined treatment plan. At least one of the individually packaged items, or the packages in which it is contained, may be identified with a predetermined time for use. The plurality of individually packaged items may be arranged sequentially according to the predetermined time for use, such as meals, times of day, days, or intervals.

The invention provides a method for providing a user with feedback on their technique when using an oral care device. The method includes recording one or more previous oral care sessions and identifying one or more oral care habits based on the recorded one or more previous oral care sessions. Feedback is generated for encouraging the user to adjust an oral care habit of the one or more oral care habits and the user is provided with the feedback during a subsequent oral care session.

The present invention relates to a vibrating toothbrush, and more particularly to a vibrating toothbrush enabled to perform toothbrushing for a running time, periodically output an alarm signal in a multisensory way to guide change of a region subject to toothbrushing, and supply driving power in the form of pulses according to a period, thereby reducing power consumption and rapid driving stress of a motor.

A voice-activated electric toothbrush system including an electric toothbrush, a charging station such as an inductive charging station that provides power to the electric toothbrush, and a voice-assistant application that may be included in the electric toothbrush or the charging station. The device that includes the voice-assistant application may also include one or more microphones for receiving voice input, such as a microphone array, and one or more speakers for providing voice output, such as a speaker array. The toothbrush and the charging station may communicate with each other via a short-range communication linkand may also communicate with a client computing device of the user via short-range communication. The electric toothbrush may include one or more sensors for detecting sensor data during a brushing session which may be used when generating the voice output.
