Apparatus for the production of sterilized calcium-ion water

An apparatus for the production of sterilized and calcium-ion water includes: a housing structure; an electrolytic cell with electrical terminals and electrodes installed in the housing structure; a plurality of electromagnetic valves separately provided at a water-intake pipe and a water-drain pipe in communication with the electrolytic cell; a setting switch disposed in the housing structure and electrically coupled with the electrolytic cell for adjusting the current intensity of electrolysis therewith; a hydraulic-pressure switch provided at a water pressure pipe for the control of the water-level in the electrolytic cell; an ultraviolet sterilizing tank connected to the electrolytic cell for sterilizing the electrolyzed water; and a control circuit respectively coupled with the electrolytic cell, the electromagnetic valves and the setting and hydraulic switches; whereby, calcium-ion water can be effectively produced for drinking purposes.

BACKGROUND OF THE INVENTION 
This invention relates to an apparatus for the production of sterilized 
calcium-ion water, and particularly to a kind of apparatus by which a weak 
alkaline calcium-ion water can be produced via the interrelated action of 
a positively charged electrode and negatively charged electrodes of an 
electrolytic cell, and sterilized through an ultraviolet tank associated 
with said electrolytic cell so as to produce healthy drinking water 
therewith. 
A calcium deficiency in the human body can lead to such serious health 
problems as rickets or osteoporosis. To make up for this deficiency, 
calcium supplements are usually administered. However, it has been found 
that an accumulation of negatively charged high-level acidic toxins in the 
human body can greatly reduce the transmission of positively charged 
calcium ions hindering the reduction of a calcium deficiency. In light of 
this, a healthy alkaline medium is needed to provide a calcium-ion 
supplement to the human body. 
SUMMARY OF THE INVENTION 
It is accordingly a primary object of the present invention to help prevent 
health problems associated with a calcium deficiency by providing an 
apparatus which produces sterilized alkaline drinking water supplemented 
with calcium-ions. 
This and other objects of the present invention are achieved by the 
provision of an apparatus for the production of a sterilized calcium-ion 
water, which apparatus comprises: a housing structure; an electrolytic 
cell having a plurality of terminals and electrode plates disposed therein 
installed in said housing structure for performing electrolysis therewith; 
a plurality of electromagnetic valves respectively provided at a 
water-intake pipe and a water-drain pipe in said housing structure and 
communicatively connected to said electrolytic cell for being actuated to 
control the intake and drain of water therefrom; a setting switch 
electrically installed therein in conjunction with said electrolytic cell 
for adjusting the current intensity of the electrolysis thereof; a 
hydraulic pressure switch disposed therein in communication with said 
electrolytic cell for controlling the water level thereof; an ultraviolet 
sterilizing means communicatively connected to said electrolytic cell for 
sterilizing the calcium-ion water produced therefrom; and a control 
circuit means electrically coupled with said electrolytic cell, said 
electromagnetic valves, said setting switch, and said hydraulic pressure 
switch for effecting electrical control operations therewith; whereby, 
calcium-ion water can be effectively produced and sterilized for drinking 
purposes. 
Other advantages and characteristics of the present invention will become 
clear from the following detailed description of a preferred embodiment 
when read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, the production process of the preferred embodiment of 
an apparatus for the production of sterilized calcium-ion water according 
to the present invention is as follows: 
Water from a water source 10 is supplied to an electrolytic cell 12 under 
the control of an activated electromagnetic water-intake valve 11 for 
performing electrolysis operations; an electrolyte-intensity setting 
switch 13, which is electrically coupled with said electrolytic cell 12, 
is adjusted to set the current intensity of electrolysis thereof. After 
the electrolysis is completed, the electrolyzed water from said 
electrolytic cell 12 is divided into alkaline water 101 and acidic water 
102 wherein said acidic water 102 is directly drained out, since it cannot 
be used for drinking, while said alkaline water flows into an ultraviolet 
sterilizing tank 15 to be sterilized therein before flowing out therefrom 
to be used for drinking purposes. In addition, the water level in said 
electrolytic cell 12 is under the control of a hydraulic pressure switch 
14. When the water level in said electrolytic cell 12 has reached a given 
level, a signal from said hydraulic pressure switch 14 will be transmitted 
to a control circuit device 18 which in turn is energized to shut off said 
electromagnetic water-intake valve 11 so that the water from said water 
source 10 no longer flows into said electrolytic cell 13. On the other 
hand, if the preferred embodiment of the calcium-ion water production 
apparatus is not going to be used for a certain length of time, the water 
in said electrolytic cell 12 can be drained out by opening an 
electromagnetic water-drain valve 16. 
Referring to FIGS. 2, 3 and 4, the embodiment of the apparatus for the 
production of calcium-ion water according to the present invention 
comprises: a housing structure (not shown); an electrolytic cell 12 with a 
plurality of terminals 121 and a plurality of electrode plates 122 which 
are respectively disposed in said electrolytic cell 12 and electrically 
coupled with said terminals, (as shown in FIG. 4), installed in said 
housing structure (not shown) for performing electrolysis operations; an 
electromagnetic water-intake valve 11 installed at a water intake pipe 110 
and an electromagnetic water-drain valve 16 installed at a water drain 
pipe 160 separately provided in said housing structure (not shown) and 
communicatively connected to said electrolytic cell 12 for separately 
effecting water intake and drain operations therewith; an 
electrolyte-intensity setting switch 13 provided on said housing structure 
and electrically coupled with said electrolytic cell 12 for adjusting the 
current intensity of the electrolysis thereof; a hydraulic pressure switch 
14 disposed at a water pressure pipe 140 in said housing structure and 
communicatively connected to said electrolytic cell 12 for controlling the 
water level therein; an ultraviolet tank 15 having an ultraviolet 
sterilizing lamp 151 installed at an outlet pipe in said housing structure 
and communicatively connected to said electrolytic cell 12 for sterilizing 
the electrolyzed water thereof and draining the sterilized water therefrom 
for drinking purposes; and a control circuit device 18 having a plurality 
of electrical elements disposed therein electrically coupled with the 
terminals 121 of said electrolytic cell 12, said electromagnetic 
water-intake and water-drain valves 11, 16, said setting switch 13, said 
hydraulic pressure switch 14 and the ultraviolet sterilizing lamp 151 of 
said ultraviolet sterilizing tank 15 for controlling and effecting 
calcium-ion water production operations. 
As shown in FIGS. 2 and 3, when the water in said electrolytic cell 12 
lowers to a certain level which is detected by said hydraulic-pressure 
switch 14, said control circuit device 18 will energize said 
electromagnetic water-intake valve 11 to open said water intake pipe 110 
and allow water to flow therefrom into said electrolytic cell 12, and, in 
the meantime, said setting switch 13 is adjusted to set the electrolysis 
intensity of said electrolytic cell 12. After the water level in said 
electrolytic cell 12 has reached a given level, said hydraulic-pressure 
switch 14 will open and said control circuit device 18 will be again 
actuated to de-energize said electromagnetic water-intake valve 11 so as 
to shut off the water-intake pipe 110 thereat. After electrolysis, the 
electrolyzed water in said electrolytic cell 12 is divided into alkaline 
water 101 and acidic water 102. Since said acidic water 102 cannot be used 
for drinking, it is directly drained from said electrolytic cell 12 
through said water-drain pipe 160. However, said alkaline water 101 will 
flow into said ultraviolet sterilizing tank 15 and be sterilized therein 
before being drained therefrom for drinking purposes. 
As shown in FIG. 4, said electrolytic cell 12 includes three electrode 
plates 122 separately disposed therein and a plurality of net-type 
filtering troughs 123 parallel positioned between said electrode plates 
122 for filtering purposes. Of the three electrode plates 122, the middle 
plate is connected to the positive terminals of the electrolytic cell 12 
while the other two at both sides thereof are connected to the negative 
terminals of the electrolytic cell 12. During electrolysis, the water 
which is electrolyzed through said positive electrode plate 122 will 
become alkaline water 101 while the water which is electrolyzed through 
said negative electrode plates 122 will become acidic water 102 in said 
electrolytic cell 12. In order to drain said alkaline water and said 
acidic water from said electrolytic cell 12, an alkaline-water outlet 124 
is provided thereat in line with said positive electrode plate 122, 
leading into said ultraviolet sterilizing tank 15, and two acidic-water 
outlets 125 are separately provided thereat in line with said two negative 
electrode plates 122, leading out of said housing structure through said 
water-drain pipe 160. In this way, the alkaline water 101 and the acidic 
water 102, produced in said electrolytic cell 12 after electrolysis, will 
flow out of respective outlets 124, 125. Furthermore, when said control 
circuit device 18 is actuated to energize said electromagnetic 
water-intake valve 16, the positive and negative polarities of the 
terminals 121 on said electrolytic cell 12 will be simultaneously changed. 
Following this polarity-change method and the instantaneous change of 
positive and negative polarities of said electrode plates 122, the soiled 
matter originally accumulated on said electrode plates 122 will be cleared 
from said electrode plates 122 so as to prevent the same from being 
etched, thereby maintaining a prolonged electrolytic life expectancy. 
Another salient feature of the present invention is the provision of said 
ultraviolet sterilizing tank 15 installed at the outlet of said alkaline 
water 101. With the ultraviolet lamp 151 being disposed in said 
ultraviolet tank 15 and operated by said control circuit device 18, said 
alkaline water 101 can be sterilized before being drained from said 
ultraviolet tank 15 for drinking purposes so as to ensure the quality 
thereof. 
The foregoing is considered as illustrative only of the principle of the 
present invention. Further, since numerous modifications and changes will 
readily occur to those skilled in the art, it is not desired to limit the 
present invention to the exact construction and operation shown and 
described, and accordingly all suitable modifications and equivalents 
which may be resorted to, fall within the scope of the present invention 
as defined in the appended claims.
