Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
248 words
An apparatus for the production of sterilized calcium-ion water comprising: a housing structure; an electrolytic cell having a plurality of positive and negative terminals and electrode means respectively disposed therein installed in said housing structure for performing electrolysis operations and producing the desired calcium-ion water through said electrode means; an electromagnetic water-intake valve installed at a water-intake pipe in said housing structure and communicatively connected to said electrolytic cell for being activated to supply water thereto; an electromagnetic water-drain valve provided at a water-drain pipe in said housing structure and communicatively connected to said electrolytic cell for being activated to drain water from said electrolytic cell; a setting switch provided at said housing structure and electrically coupled with said electrolytic cell for being operated to adjust the current intensity of the electrolysis thereof; a hydraulic-pressure switch provided at a water-pressure pipe in said housing structure and communicatively connected to said electrolytic cell for being actuated to detect the water level therein and control water intake through said electromagnetic water-intake valve; an ultraviolet sterilizing tank having an ultraviolet lamp electrically disposed therein installed at an outlet pipe communicatively connected to said electrolytic cell for sterilizing desired water produced therefrom before draining out for drinking purpose; and a control circuit electrically coupled with said electrolytic cell, said electromagnetic water-intake and water-drain valves, said setting switch, said hydraulic-pressure switch and said ultraviolet sterilizing tank for effecting control operations therewith; whereby, calcium-ion water can be effectively produced and sterilized for drinking purposes.
Claim 2
Independent Claim
248 words
An apparatus for the production of sterilized calcium-ion water comprising: a housing structure; an electrolytic cell having a plurality of positive and negative terminals and electrode means respectively disposed therein installed in said housing structure for performing electrolysis operations and producing the desired calcium-ion water through said electrode means; an electromagnetic water-intake valve installed at a water-intake pipe in said housing structure and communicatively connected to said electrolytic cell for being activated to supply water thereto; an electromagnetic water-drain valve provided at a water-drain pipe in said housing structure and communicatively connected to said electrolytic cell for being activated to drain water from said electrolytic cell; a setting switch provided at said housing structure and electrically coupled with said electrolytic cell for being operated to adjust the current intensity of the electrolysis thereof; a hydraulic-pressure switch provided at a water-pressure pipe in said housing structure and communicatively connected to said electrolytic cell for being actuated to detect the water level therein and control water intake through said electromagnetic water-intake valve; an ultraviolet sterilizing tank having an ultraviolet lamp electrically disposed therein installed at an outlet pipe communicatively connected to said electrolytic cell for sterilizing desired water produced therefrom before draining out for drinking purpose; and a control circuit electrically coupled with said electrolytic cell, said electromagnetic water-intake and water-drain valves, said setting switch, said hydraulic-pressure switch and said ultraviolet sterilizing tank for effecting control operations therewith; whereby, calcium-ion water can be effectively produced and sterilized for drinking purposes.
Claim 3
Dependent Claim
75 words
An apparatus according to claim 1 wherein said electrode means comprises three electrode plates parallel installed in said electrolytic cell wherein one intermediate electrode plate is connected to the positive terminals of said electrolytic cell while other two electrode plates are connected to the negative terminals of said electrolytic cell so that, by an interrelated action of one positive polarity and two negative polarities of said electrode plates, weak-alkaline calcium-ion water can be produced therefrom.
Claim 4
Dependent Claim
27 words
An apparatus according to claim 2 wherein said electrolytic cell further comprises a plurality of net-type filtering troughs parallel positioned between said electrode plates for filtering purposes.
Claim 5
Dependent Claim
79 words
An apparatus according to claim 2 wherein said electrolytic cell further comprises an alkaline-water outlet provided therein in line with said positively terminated intermediate electrode plate, leading to said ultraviolet sterilizing tank, and a pair of acidic-water outlets located therein respectively in line with said negatively terminated electrode plates, leading into said water-drain pipe; whereby, alkaline water and acidic water, produced in said electrolytic cell after electrolysis, can flow respectively out of said alkaline-water outlet and said acidic-water outlets.
