A fluid dispensing brush for applying a fluid to hair includes a plurality of bristles that is coupled to and extends from a housing. The bristles are tubular and are in fluidic communication with an interior space defined by the housing. Each of a plurality of holes is positioned in a respective bristle. A handle extends from a first end of the housing. A channel extends through the handle to the housing. A pump is positioned in the channel proximate to the housing and is in fluidic communication with the interior space. A reservoir is selectively insertable into the channel so that a nozzle of the reservoir sealably couples to an inlet of the pump. The pump is configured to selectively pump a fluid that is positioned in the reservoir through the interior space and the bristles to exit through the holes to apply the fluid to the hair.

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.

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.

The present invention relates to an improved brush, in particular a brush for facial care, with several carriers including cleaning elements and each connected to a shaft, and a casing that pivotably mounts said carriers and that supports a common drive shaft for said carriers and which is drive-coupled to said shafts.

A body cleaning device is disclosed. The body cleaning device comprises a body cleaning assembly, a head massage assembly, and a facial cleaning assembly. The facial cleaning assembly can accommodate in an accommodating space which is formed by the body cleaning assembly and the head massage assembly. The body cleaning assembly is provided with a plurality of silicon brushes over a helmet thereon. The head massage assembly is provided with a plurality of protruding cylinders on a upper cover thereon. The facial cleaning assembly is provided with a plurality of facial silicon brushes over its surface. The body cleaning device can deep clean a body and a face by vibrating.

An oral care system may include: an oral care device including: at least one teeth cleaning element; and at least one sensor configured to detect motion of the oral care device during a brushing routine of a user and to generate sensor data corresponding to the detected motion; and a programmable processor configured to: receive the sensor data generated by the at least one sensor; and determine a target brushing time based on the sensor data.

Skin brush heads configured for use with a motorized personal appliance include a body having an inner surface and an outer surface, and a treatment applicator coupled to the outer surface of the body. The treatment applicator includes a plurality of cleansing agent-infused bristles extending away from the outer surface of the body, the plurality of cleansing agent-infused bristles being configured to remove particles from a skin portion by adsorption.

The present disclosure is concerned with a personal care device having a head portion having a driven treatment head, a handle portion having a drive unit for providing a motion having a motion direction, and a drive train extending between the drive unit and the driven treatment head for transmitting the motion from the drive unit to the driven treatment head, the drive train having a separable coupling. The separable coupling has a first coupling part having a first coupling element, a second coupling part having a second coupling element, the first and the second coupling elements being separably engaged with each other, and a resilient element biasing the first coupling element and the second coupling element against each other so that the first and second coupling elements are engaged in a gap-free manner along the motion direction.

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.

Personal care devices (or apparatuses) are described to deliver/activate a bioactive compound/botanical compound/biologically active molecule (including a regulatory protein/growth factor) or a mixture of bioactive compounds/botanical compounds/biologically active molecules (including regulatory proteins/growth factors) for growth and protection of hair or rejuvenation and protection of skin, which utilizes nanoencapsulation/nanoemulsion and/or activation/photoactivation. Such devices (or apparatuses) utilize a light low intensity module/x-ray and nanooptical elements/three-dimensionally (3-D) printed micro/nanostructures. Furthermore, the personal care devices (or apparatuses) can be enhanced with an artificial intelligence (AI) algorithm and/or augmented reality (AR) application (app).
