A FAUCET MOUNTED LIQUID FORTIFICANT DOSING DEVICE AND DISPENSION METHOD

摘要

Disclosed is a liquid fortificant dosing device that can be fitted to a faucet of a water storage chamber and particularly fitted to a faucet of a storage chamber of water purification devices which provide purified potable water and at the same time provide beneficial amounts of fortificants e.g. 10to 20% RDA/Litre of water are made available in every unit of water that is dispensed. The disclosed device has a dispensing unit which is suitable for comprising fortificant stock solution having viscosity in the range of 50 to 2000 cP, said unit having an opening (2) to the atmosphere positioned above the level of said solution; a differential pressure unit (3),comprising an inlet port (4) connectable to said faucet (8), and an outlet port (5) to dispense fortified water; a dosing tube (7) having a diameter in the range of 0.5 to 3 mm connected at one end to the point of minimum pressure(6) of said differential pressure unit (3) while the other end of the dosing tube (7) dips into said solution; wherein a vent (10) is provided to the atmosphere upstream of said point of minimum pressure (6) in said differential pressure unit (3) and wherein flow rate of water through said faucet (8) is controlled to a substantially constant rate by a mechanical flow control element (11) that is positioned upstream of the differential pressure unit (3).
