Abstract:
An apparatus for supplying deozonized ozone sterilized water, comprising:a water supplying conduit adapted for water stream flow, said conduit including a water feeding inlet which is adapted to be in fluid communication with a water source, an outlet for delivering the deozonized ozone sterilized water and disposed downstream of said water feeding inlet, and an intermediate treatment section which is disposed upstream of said outlet and downstream of said water feeding inlet, and which has at least a first transmissible portion that is made from an ultraviolet radiation permeable material; an ozone-containing gas generating member including a feeding end for entry of oxygen-containing gas, a gas removing end disposed downstream of said feeding end, and an ozone-containing gas generating section disposed upstream of said gas removing end and downstream of said feeding end; a first ultraviolet lamp unit disposed to irradiate the oxygen-containing gas flowing through said ozone-containing gas generating section to produce an ozone-containing gas; a cooling system disposed to cool said ozone-containing gas generating section when the oxygen-containing gas flowing therein is irradiated by said first ultraviolet lamp unit; a gas introducing valve including a proximate end disposed to be in fluid communication with said water supplying conduit at a position which is downstream of said water feeding inlet and upstream of said intermediate treatment section, and a distal end disposed to be in fluid communication with said gas removing end so as to entrain the ozone-containing gas in the water stream; and a second ultraviolet lamp unit disposed adjacent to said first transmissible portion of said intermediate treatment section to irradiate said intermediate treatment section to break down the ozone entrained in the water stream flowing therethrough, thereby delivering the deozonized ozone sterilized water out of said outlet.
