A combination electric toothbrush and water irrigation device that combines a battery powered water irrigation device with a vibrating electric toothbrush, both of which are housed in a self-contained compact hand-held device. The pump for the water irrigation device and the DC motor with an off-center weight are contained within the handle of the toothbrush. A slide out water reservoir allows the user to fill the extended handle portion with water. A flexible water inlet tube is capable of compressing when the water reservoir is in the storage position. A weight fixed to the end of the inlet tube causes the tube to bend via gravity enabling it to be in constant contact with water while the handle is held at various angles. An LED at the underside of the pump housing illuminates the water contained within the transparent water housing.

A toothbrush assembly comprises an elongated handle portion, a head portion at one end and having toothbrush bristles thereon, and an opposite end within which an indicator, comprising a timer mechanism and a light, is provided for providing the user with a predeterminedly defined timed period for brushing one's teeth. The entire assembly is made as a one-piece assembly such that various components do not become separated from each other, the assembly is fabricated from a thermoplastic material which is transparent such that inner components are visible, and the toothbrush assembly is also adapted to accommodate a three-month supply of toothpaste after the depletion of which the entire assembly can be discarded. A timer is provided for defining the predeterminedly defined timed period, and one or more lights, preferably LEDs, can be illuminated at the end of the timed period or can flash throughout the timed period and then be extinguished at the conclusion of the timed period. Having the lights constantly flash throughout the timed period permits users, particularly children, to brush their teeth in a dark environment, a feature that they may find fun and interesting, and therefore serve as an inducement for them to regularly brush their teeth.

End effectors and systems including end effectors configured to provide colorimetric indicia of a wear state of the end effector are described. In one embodiment, the end effector includes: a base portion coupleable to a motor; a chamber including an optically translucent window and a chamber interior; and a flowable material disposed in the chamber interior and having a color. The end effector is configured to provide colorimetric indicia of a wear state of the end effector based at least in part on mixing of the flowable material.

A brush has a hollow body having a working surface, a reservoir for a fluid inside the body, a valve to dispense fluid contained in the reservoir through a nozzle onto a surface to be engaged by the working surface of the brush and an activation mechanism for the valve, further comprising on a side of the body opposite the working surface, an opening or window through which a fluid level in the reservoir can be observed.

A conditioning and styling reactivated hair device is an apparatus which can be used to spray formulations to condition, style, reactivate, and/or refresh hair, stimulate the scalp, and help detangle hair. The apparatus includes a handheld grip, a detachable panel, a nebulizing mechanism, a vibration mechanism, and a control system. The handheld grip serves as the base for the apparatus which can be ergonomically held by one hand. Further, the handheld grip includes a palm-bearing surface and an interfacing surface. The detachable panel covers the internal structure of the handheld grip and supports external hair styling aids. The detachable panel further comprises a back plate and a flow guide. The nebulizing mechanism dispenses spray formulations stored within the handheld grip. The vibration mechanism generates physical vibrations for stimulating purposes as well as to aid in dispensing spray formulations. The control system enables the semi-automatic operation of the apparatus by users.

A toothpaste dispensing toothbrush has a longitudinal, hollow, cylindrical housing, an open distal end, and an open proximal end. The distal end is tapered to a blunt, open extremity. The proximal end has a predetermined inside diameter. The cylindrical housing also has a transparent longitudinal window located along its outer surface. A toothbrush head is removably affixed to the distal end of the housing. A hollow, cylindrical toothbrush cartridge chamber has an open proximal end and an outside diameter smaller than the inside diameter of the housing proximal end, to facilitate insertion of the cartridge chamber into the proximal end of the housing. A movable piston is disposed in the cartridge chamber and a slidable button is located on the housing and connected to the movable piston. A dome cap is removably affixed to the proximal end of the cartridge chamber to retain toothpaste introduced into it. A dental floss container can be removably attached to the toothbrush and an LED light can be added to illuminate areas of the mouth being brushed.

A toothbrush comprising a brush head and neck, a hollow toothpaste storage chamber, and a plunger, in which the brush head has bristles and one or more apertures, and the neck is hollow. A portion of the plunger sits inside of the hollow storage chamber, and a spring sits inside of the hollow plunger. Alternatively, the plunger has a rod that has teeth on one side and a groove on the other side, to lock or unlock the plunger.

A method of providing a visual indication of depletion of an oral care fluid. In one aspect, the method provides a visual indication of depletion of an oral care fluid contained within a reservoir of an oral care implement having a delivery member formed of a capillary material. The method includes: a) providing an indicator fluid in the reservoir with the oral care fluid, the oral care fluid being a different color than the indicator fluid and immiscible with respect to the indicator fluid; and b) upon depletion of the oral care fluid from the reservoir, delivering the indicator fluid to a visible portion of the deliver member.

A disposable toothpaste dispensing toothbrush system and method includes a device that combines a toothbrush with a changeable head assembly connected to a body assembly that is filled with toothpaste for single or multi use. The disposable toothpaste dispensing toothbrush system and method is useful for improving the convenience of brushing teeth at home or while away from home by offering the convenience of a tooth brush filled with toothpaste with advantages for venting while filling and sealing toothpaste from hardening or drying out.

A dental cleaning appliance includes a nozzle having a fluid chamber, a fluid outlet and a channel extending between the fluid chamber and the fluid outlet. A water reservoir provides water to a pump for generating a burst of pressurized water, which is supplied to the nozzle by a fluid conduit. Following the delivery of the burst of water to the teeth of the user, a valve draws water back into the fluid chamber from the channel to prevent that water from dripping from the fluid outlet before the next water burst is generated by the pump. Simultaneously, air may be drawn into the fluid chamber, for example, through the fluid outlet, for mixing with the next water burst to generate a fluid burst for delivery to the user's teeth.
