Abstract
This invention relates to a device for whitening teeth, including both a tank (16) for at least part of the whitening product in solid or semi-solid form, and a tank (17) of a product in liquid form and means designed to mix the products in powder form and in liquid form before they come out of a nozzle (14), the device also includes a duct (18) leading to the nozzle (14) and operatively connected to a pressurized energy source (219) from which, on command, a flow of gas extends; operatively connected in an intermediate position of a first stretch (18A) of the duct (18) there being the tank (16) of at least part of the whitening product; operatively connected in an intermediate position of a second stretch (18B) of the duct (18) there being the tank (17) of product in liquid form.
Claims4
A device for whitening teeth, comprising a dispenser (11) equipped with a zone to be gripped (13) by the user and a nozzle (14) for ejecting a flow of whitening product, characterised in that the device comprises a first tank (16) comprising at least part of the whitening product in a powder form or a liquid mixture, fixed to said dispenser (11) in such a way as to move together with said dispenser during movements of a hand of the user, and a pressure energy source (19, 119) comprising a compressor;
- said device comprising a second tank (17) comprising a product in liquid form;
- said device comprising a means for mixing said at least part of the whitening product and said product in liquid form, the mixing means comprising a duct (18) leading to said nozzle (14) and operatively connected to said pressurised energy source (19, 119) from which, on command, a flow of gas extends;
- said duct (18) comprising a first stretch (18A) and a second stretch (18B);
- said first tank (16) being connected to an intermediate portion of the first stretch (18A) so that the passage of the flow of gas through said intermediate portion of said first stretch (18A) causes the suction and intake into the duct of said at least part of the whitening product by Venturi effect;
- said second tank (17) being connected to an intermediate portion of the second stretch (18B) so that the passage of the flow of gas through said intermediate portion of said second stretch (18B) causes the suction and intake into the duct (18) of said product in liquid form by Venturi effect;
- said at least part of the whitening product and said product in liquid form mixing before corning out of the nozzle (14).
