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.
Cette invention concerne une installation d'hygiène dentaire et de conservation de l'eau pour applications domestiques. L'installation comprend un réservoir alimenté par un tuyau d'amenée d'eau et adapté pour que l'air y contenu soit comprimé à mesure qu'il se remplit. Un instrument d'hygiène dentaire raccordé au réservoir par des flexibles est alimenté en eau et en air sous pression simultanément, l'eau ainsi puisée passant d'abord dans une cartouche renfermant des matières abrasives pour entraîner celles-ci vers ledit instrument. Le réservoir est également raccordé à un appareil sanitaire tel que pomme de douche pour servir à la conservation de l'eau. Ce raccordement permet de soutirer l'eau qui s'est refroidie dans le tuyau d'alimentation en eau chaude et la réutiliser plus tard. Selon l'invention, l'eau de recyclage est réaspirée vers l'appareil sanitaire lorsque celui-ci est ouvert.
