The apparatus for bodily care, in particular for massaging the gums and cleaning the teeth, by means of a jet of liquid pulsed by a piston pump, comprises a working chamber (4) connected to an outlet conduit (5), in which chamber the piston (6) is driven with reciprocating movements by an electric motor, an admission chamber (2) connected to an admission conduit (3) and an admission valve (9) arranged in the communication opening between the admission (2) and working (4) chambers, and a reservoir of liquid (12) connected to the admission conduit for feeding a spraying nozzle (17) connected to the outlet conduit (5). The movable part (9a, 9b) of the admission valve (9) is accommodated freely and easily movable without any stress.

A toothbrush connectable to a pressurized source of water for expelling a stream of pulsating water from the brush head thereof is provided. The toothbrush, includes: a body having a conduit therein in fluid communication between a water inlet and a plurality of holes formed in the brush head of the body, a flexible hose having a first end connected to the water inlet and a second end connectable to a pressurized source of water and a pulsatile mechanism in operational connection with the conduit for transforming the flow of water therethrough the conduit into a pulsating stream of water expelled from the holes.

A dental prophylaxis and water conservation device for in-home use. The device includes a tank coupled to the household water supply line and adapted to receive water which causes air contained within the tank to be pressurized. The water and air from within the tank are connected by lines to a handpiece which discharges both mediums simultaneously. Water leaving the tank passes through a container having an abrasive material which is picked up by the water and also discharged. The tank is further coupled to a plumbing fixture, such as a shower head. This enables the tank to be used as a water conservation device by allowing cold water to be purged from a hot water line into the tank, and subsequently used to provide water to the plumbing fixture. To recycle the purged water, the present invention entrains the water from within the tank as water from the supply line is being provided to the plumbing fixture.

An apparatus designed to clean surfaces and to recycle the cleaning solution including a hand-holdable housing, a tube having a lumen through which cleaning solution may be impelled, a pump for both impelling and urging solution back through a return path. Piston-based, in particular a ganged pump using a stepped piston, as well as membrane-based pumps are disclosed. Methods of cleaning surfaces using such apparatuses as well as a system for periodically cleaning a plurality of surfaces are disclosed as additional embodiments.

An apparatus designed to clean surfaces and to recycle a cleaning fluid. The apparatus has a hand-holdable housing that includes a head with a distal end through which cleaning solution may be impelled. The apparatus further has a pump for both impelling and urging cleaning fluid back through a return path. The pump has a flexible membrane and a pump drive mechanism in which two pistons drive the flexible membrane. The cleaning fluid includes a foaming-resistant composition that has an abrasive agent; a shear thinning fluid matrix, and a non-foaming means.
